technical field

The present application relates to the technical field of communication, and in particular to a signal transmission method and a communication device.

Background technique

The radar communication integration technology can realize the functions of radar detection and data transmission at the same time. That is, the network device can not only send a radar detection signal to realize the radar detection function, but also send a synchronization signal block (synchronization signal block, SSB) signal to synchronize between the terminal device and the network device to realize the data transmission function.

Contents of the invention

Embodiments of the present application provide a signal transmission method and a communication device, which can avoid interference between a first signal (such as a radar detection signal) and a synchronization signal block SSB signal, and improve system communication efficiency.

In order to achieve the above purpose, the embodiment of the present application adopts the following technical solutions:

In the first aspect, the embodiment of the present application provides a signal transmission method, and the execution subject of the method may be a network device, or may be a chip applied in the network device. The following description is made by taking the execution subject as an example of a network device. The method includes: the network device determines the first resource, wherein the first resource and the second resource do not overlap in the time domain, the second resource is used to send a synchronization signal block SSB signal, and there is a corresponding relationship between the first resource and the second resource. Then, the network device transmits at least one first signal on the first resource, where the first signal is used to detect the attribute of the target. Wherein, there is a corresponding relationship between the first resource and the second resource, which means that there is a corresponding relationship between the first resource and the second resource in terms of resource positions.

That is to say, the first resource determined by the network device is a resource that does not overlap with the second resource in the time domain, and there is a corresponding relationship between the two resources in terms of resource positions. In this way, the sending time of the first signal and the SSB signal are different, so that the first signal and the SSB signal do not collide and interfere with each other, thereby improving the communication efficiency of the system.

In a possible design, within the target duration, the first resource does not include the resource overlapping with the candidate position of the SSB signal in the third resource. Wherein, the target duration is constituted by at least one time slot where the second resource is located, and the third resource is determined based on the transmission period of the first signal.

That is to say, the first resource is the third resource except the resource overlapping with the candidate position of the SSB signal, so the network device does not transmit the first signal and the SSB signal at the same time, thereby avoiding the collision between the first signal and the SSB signal, so as to improve System communication efficiency.

In a possible design, when some resources in the third resource overlap with the candidate positions of the SSB signal, the first resource at least includes: advancing or delaying the resources overlapping with the candidate positions of the SSB signal among the third resources by at least one Resources following the time domain notation.

That is to say, in the case that part of the resources in the third resource overlap with the candidate positions of the SSB signal, move (for example, advance or delay) the resources overlapping with the candidate positions of the SSB signal, so as to prevent the network device from transmitting the first signal and the candidate position of the SSB signal at the same time. SSB signal.

In a possible design, within the target duration, the first resource is composed of resources among the third resources that do not overlap with candidate positions of the SSB signal.

That is to say, none of the resources constituting the first resource overlap with the candidate positions of the SSB signal, thereby preventing the network device from simultaneously transmitting the first signal and the SSB signal.

In a possible design, the first resource is determined based on the second resource. That is to say, the first resource is adjusted based on the second resource, so that the first resource and the second resource do not overlap in the time domain.

In one possible design, the first spacing is different from the second spacing. Wherein, the first interval is an interval between two adjacent first signals in the at least one first signal within the target duration. The second interval is an interval between two adjacent first signals in the at least one first signal outside the target duration. The target duration is formed by at least one time slot where the second resource is located.

That is to say, the time interval between two adjacent first signals within the target duration is different from the time interval between two adjacent first signals outside the target duration.

In a possible design, there are multiple first intervals, and the time lengths of the multiple first intervals are the same. Wherein, there are multiple first intervals, which means that the network device transmits multiple first signals within the target duration, and there is a first interval between every two adjacent first signals. Thus, the number of first intervals is plural. In other words, the first signal is still transmitted at equal intervals within the target duration.

In a possible design, within the target duration, the first resource includes a time-domain resource unit whose index value is a first preset value.

In a possible design, the time-domain resource unit is a time-domain symbol, and the first preset value includes one of the following: 0, 1, 12, or 13.

That is to say, when the subcarrier interval for transmitting SSB signals is 120kHz, with a single time slot as the granularity, the time-domain symbol indexes that the second resource does not occupy are as follows: 0, 1, 12, and 13, so, the first A resource occupies one of symbols 0, 1, 12, or 13 in a time slot within the target duration, and does not overlap with the second resource in the time domain, thereby avoiding collision between the first signal and the SSB signal.

That is to say, there are at least three first resources in every two consecutive time slots. In other words, at least three first signals are transmitted in every two time slots, which improves the time-domain density of the first signals and is beneficial to improving radar detection accuracy. Moreover, the difference between any two items in the second preset value is greater than or equal to the third preset value, which makes the first resource discontinuous in the time domain, thereby ensuring the first signal to a certain extent Evenly distributed.

In the process of N traversing 28 integers (from 0 to 27), the time-domain symbol index carrying the SSB signal is not equal to the time-domain symbol index of the first resource, so as to avoid the overlap between the first resource and the second resource in the time domain .

Wherein, M represents the fourth preset value, and the value of N includes at least two of the following: 0, 1, 2, 7, 8, 9, 14, 15, 16, 21, 22, or 23.

In this embodiment of the application, "transmitting" may include "sending" or "receiving", depending on the specific circumstances, and may also include sending and receiving.

First, introduce the technical terms involved in this application:

1. Synchronization signal block (SSB) signal

In new radio (new radio, NR), network equipment periodically sends SSB signals. An SSB signal includes a synchronization signal (synchronization signal, SS) and a physical broadcast channel (physical broadcast channel, PBCH). Wherein, the SS includes a primary synchronization signal (primary synchronization signal, PSS) and a secondary synchronization signal (secondary synchronization signal, SSS). The terminal equipment identifies the cell and synchronizes with the cell through the PSS and SSS. The terminal equipment obtains the most basic system information through the PBCH, such as the system frame number, timing information within the frame, and so on. The successful reception of the SSB signal by the terminal equipment is the prerequisite for it to access the cell.

As shown in FIG. 1 , in the time domain, one SSB signal occupies 4 time domain symbols, for example, the 4 time domain symbols numbered 0 to 3 in FIG. 1 . In the frequency domain, an SSB signal occupies 20 resource blocks (resource block, RB), that is, 240 subcarriers, and within the 20 RBs, subcarriers are numbered from 0 to 239. The PSS is located on the middle 127 subcarriers of time domain symbol 0, and the SSS is located on the middle 127 subcarriers of time domain symbol 2. In order to protect the PSS and SSS, different guard subcarriers are set to 0 respectively, that is, the guard subcarriers are not used to carry signals, and 8 subcarriers and 9 subcarriers are reserved on both sides of the SSS as guard band subcarriers, such as The blank areas on both sides of the SSS in FIG. 1 are guard subcarriers. PBCH occupies all the subcarriers of time-domain symbol 1 and time-domain symbol 3, and occupies all subcarriers of time-domain symbol 2 except for the subcarriers occupied by SSS. subcarriers except the guard subcarriers).

An SSB signal is associated with an index to identify the SSB signal. In a half frame, when the index of an SSB signal is 0, the SSB signal identified by the index is the first SSB signal in the half frame; when the index of an SSB signal is 1, the SSB signal identified by the index is the first SSB signal in the half frame. The second SSB signal in the frame, others can be deduced by analogy. Exemplarily, in FIG. 2 a , the SSB signal identified by index 0 is the first SSB signal in a field, and the indices of symbols in the time domain occupied are 4 to 7. The SSB signal identified by index 1 is the second SSB signal in the field, and the indices of the symbols in the time domain occupied are 8 to 11. The SSB signal identified by index 2 is the third SSB signal in the half-frame, and the indices of the occupied time domain symbols are 16 to 19. The SSB signal identified by index 3 is the fourth SSB signal in the half-frame, and the indices of symbols in the time domain occupied are 20 to 23. In Figure 2b, the SSB signal identified by index 0 is the first SSB signal in the half-frame, and the indices of the occupied time domain symbols are 4 to 7, and the SSB signal identified by index 1 is the second SSB signal in the half-frame, The indices of the occupied time domain symbols are 16 to 19. Two SSB signals that are consecutive in index may be continuous in time domain, such as the SSB signal identified by index 0 and the SSB signal identified by index 1 in FIG. 2 a . The two SSB signals that are continuous in the index may also be discontinuous in the time domain, such as the SSB signal identified by index 0 and the SSB signal identified by index 1 in FIG. 2 b .

It should be noted that if the subcarrier spacing (subcarrier spacing, SCS) for transmitting the SSB signal is different, the candidate positions of the SSB signal are also different. Below, based on different subcarrier spacings, five cases (cases) are used to introduce the candidate positions of the SSB signal:

Case A, when the SCS is 15kHz, the time-domain symbol index of the SSB signal satisfies:

{2, 8}+14*n formula (1)

In the case of no shared spectrum channel access, if the carrier frequency is less than or equal to 3GHz, then n=0,1; if the frequency range (frequency range) is greater than 3GHz, then n=0,1,2,3. In the case of shared spectrum channel access, n=0, 1, 2, 3, 4.

Exemplarily, in the case of shared spectrum channel access, there are at most 10 candidate positions for the SSB signal. In the case of n=0, it corresponds to the candidate positions of two SSB signals. Wherein, the first time-domain symbol index of the first candidate position is 2, and the first time-domain symbol index of the second candidate position is 8.

Case B, when the SCS is 30kHz, the time-domain symbol index of the SSB signal satisfies:

{4, 8, 16, 20}+28*n formula (2)

Wherein, if the carrier frequency is less than or equal to 3GHz, then n=0, and if the frequency range is greater than 3GHz, then n=0,1.

In case C, when the SCS is 30kHz, the time-domain symbol index of the SSB signal satisfies:

{2, 8}+14*n formula (3)

Wherein, in the case of no shared spectrum channel access, for the paired spectrum, if the carrier frequency is less than or equal to 3GHz, then n=0,1, if the frequency range is greater than 3GHz, then n=0,1,2, 3. For spectrum without pairing, if the carrier frequency is less than 1.88GHz, then n=0,1; if the frequency range is greater than or equal to 1.88GHz, then n=0,1,2,3. In the case of shared spectrum channel access, n=0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

Case D, when the SCS is 120kHz, the time-domain symbol index of the SSB signal satisfies:

{4, 8, 16, 20}+28*n formula (4)

Wherein, if the carrier frequency band belongs to frequency range 2 (frequency range 2, FR2), then n=0, 1, 2, 3, 5, 6, 7, 8, 10, 11, 12, 13, 15, 16, 17, 18.

Case E, when the SCS is 240kHz, the time-domain symbol index of the SSB signal satisfies:

{8, 12, 16, 20, 32, 36, 40, 44}+56*n formula (5)

Wherein, if the carrier frequency band belongs to FR2, then n=0, 1, 2, 3, 5, 6, 7, 8.

It should be noted that during the synchronization process between the terminal device and the network device, the terminal device receives the SSB signal from the network device at the candidate position of the SSB signal according to the agreement, and the network device does not need to indicate the SSB signal for the terminal device candidate positions. The above formulas (1) to (5) all indicate the index of the first time-domain symbol of the candidate position of the SSB signal.

2. Frequency range

In the 3rd Generation Partnership Project 3GPP agreement, the overall spectrum resource of the 5th generation mobile communication technology (the 5th generation mobile communication technology, 5G) network can be divided into the following two frequency ranges, as shown in Table 1 below:

Table 1

frequency range name Frequency Range FR1 410MHz–7125MHz FR2 24250MHz–52600MHz

It should be understood that the names of FR1 and FR2 above shall not constitute any limitation to the present application. This application does not exclude the possibility of defining other names in future agreements to represent the same or similar meanings.

FR1: Sub 6G frequency band, in other words, low-frequency frequency band, is the main frequency band of 5G network. In FR1, the frequency below 3GHz can be called Sub 3G, and the rest of the band can be called C-band. It should be understood that the frequency range corresponding to FR1 may correspond to 410MHz-7125MHz as shown in Table 1, but is not limited thereto, and this application does not exclude the possibility of defining other ranges in future agreements to represent the same or similar meanings.

FR2: Millimeter waves above 6G, in other words, high-frequency frequency bands, which are extended frequency bands for 5G networks, with rich spectrum resources. It should be understood that the frequency range corresponding to FR2 may correspond to 24250MHz-52600MHz as shown in Table 1, but is not limited thereto, and this application does not exclude the possibility of defining other ranges in future agreements to represent the same or similar meanings.

3. Radar detection

The radar device emits a radar detection signal, and the radar detection signal encounters a target object and is diffusely reflected to form an echo signal. The radar device receives the echo signal reflected by the target object, and realizes the detection of the target object based on the radar detection signal and the echo signal, such as determining the distance, orientation, height, speed, attitude, shape and other characteristic quantities of the target object. Wherein, the radar device may also be referred to as radar, detector, or radar detection device.

Radar detection, which can also be described as radar perception, is mostly used in scenarios such as traffic detection and weather monitoring. However, if the radar is used alone to detect a wide range, there will be a higher cost. Therefore, integrating the rich spectrum resources of wireless communication with radar detection can support large-scale requirements such as continuous networking.

4. Radar communication integration

The integration of radar communication refers to the simultaneous realization of radar detection and data transmission by sharing hardware equipment. After the radar detection function is integrated into the network device, the network device not only sends the radar detection signal to realize the radar detection function, but also sends the SSB signal to synchronize the terminal device and the network device to transmit data.

However, when the transmission resources of the radar detection signal overlap with the transmission resources of the SSB signal, that is, the network equipment transmits the radar detection signal and the SSB signal at the same time, interference between different signals is likely to occur, affecting the normal transmission of the radar detection signal and the SSB signal , the system communication efficiency is low.

In view of this, an embodiment of the present application provides a signal transmission method, and the signal transmission method of the embodiment of the present application is applicable to various communication systems. The signal transmission method provided in the embodiment of the present application may be applied to a long term evolution (long termevolution, LTE) system, or a 5G network, or other similar networks, or other networks in the future. FIG. 3 is a schematic structural diagram of a communication system applicable to the signal transmission method of the embodiment of the present application. The communication system includes a network device 301 and terminal devices 302-307. Figure 3 shows only one network device and six terminal devices. FIG. 3 is only a schematic diagram, and does not constitute a limitation on applicable scenarios of the signal transmission method in the embodiment of the present application.

Wherein, the terminal equipment may also be called user equipment (user equipment, UE), terminal, access terminal, subscriber unit, subscriber station, mobile station, remote station, remote terminal, mobile equipment, user terminal, wireless communication device, user agent or user device, etc. The terminal device can be a wireless terminal or a wired terminal. A wireless terminal can refer to a device with wireless transceiver functions, which can be deployed on land, including indoor or outdoor, hand-held or vehicle-mounted; it can also be deployed on water (such as ships, etc.); it can also be deployed in the air (such as aircraft, balloons and satellites, etc.).

The terminal device may also be a terminal in a next-generation communication system, for example, a terminal in a 5G communication system or a terminal in a future evolved public land mobile network (public land mobile network, PLMN), etc., which is not limited in this embodiment of the present application . Exemplarily, in FIG. 3 , the terminal device may be a high-speed rail communication device 302, a smart air conditioner 303, a smart fuel dispenser 304, a mobile phone 305, a smart teacup 306, a printer 307, etc., which are not limited in this embodiment of the present application.

The multiple physical entities can be deployed at the same location or at different locations. The multiple physical entities are used to jointly realize the functions of the network entity .

The communication system and business scenarios described in the embodiments of the present application are for more clearly illustrating the technical solutions of the embodiments of the present application, and do not constitute limitations on the technical solutions provided by the embodiments of the present application. Those skilled in the art know that with the evolution of the network architecture and the emergence of new service scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

In the following, the signal transmission method provided by the embodiment of the present application will be described in detail. The technical idea of the signal transmission method in the embodiment of the present application is as follows: the network device determines the first resource, wherein the first resource and the second resource do not overlap in the time domain, the second resource is used to send the synchronization signal block SSB signal, and the first resource There is a corresponding relationship with the second resource. Then, the network device transmits at least one first signal on the first resource, where the first signal is used to detect the attribute of the target. That is to say, the first resource determined by the network device is a resource that does not overlap with the second resource in the time domain, and there is a corresponding relationship between the two resources in terms of resource positions. In this way, the transmission times of the first signal and the SSB signal are different, so that the first signal and the SSB signal do not collide and interfere with each other, thereby improving system communication efficiency. Exemplarily, the first signal may be a radar detection signal, or may be an echo signal of the radar detection signal. There is a corresponding relationship between the first resource and the second resource. For specific description, please refer to the following introduction, which will not be repeated here.

As an implementation manner, the first resource is determined based on the second resource. That is to say, when the resource position of the second resource remains unchanged, the resource position of the first signal is adjusted to obtain the first resource, so that the first resource and the second resource do not overlap in the time domain. Wherein, the second resource is a resource for sending the SSB signal determined from the candidate positions of the SSB signal. In the embodiment of the present application, the candidate positions of the SSB signal are the candidate positions stipulated in 3GPP protocol technical specification (technical specification, TS) 38.213. For details, refer to the introduction of the above five situations.

As another implementation manner, the second resource is determined based on the first resource. That is to say, when the transmission period of the first signal remains unchanged, the candidate positions of the SSB signal are adjusted to obtain the second resource, so that the first resource and the second resource do not overlap in time domain.

The embodiments of the present application will be described below with reference to specific examples. The name of the message between network elements or the name of each parameter in the message in the following embodiments is just an example, and other names may also be used in specific implementations. In the embodiment of the present application, when a single time slot is used as the granularity, and the prefix of the time domain symbol is a normal cyclic prefix (normal cyclic prefix, NCP), the index value range of the time domain symbol is [0, 13]. When two consecutive time slots are used as the granularity, the index value range of the time domain symbol is [0, 27]. The first resource is used to transmit at least one first signal. The second resource is used to transmit at least one SSB signal. The third resource is a resource determined based on the transmission period of the first signal, that is, the resource where the first signal resides without considering the interference with the SSB. There is a corresponding relationship between the first resource and the second resource, which may mean that in the preset number of time domain resource units, there is a corresponding relationship between the first resource and the second resource in resource positions, such as one first resource and multiple second resources. Each second resource among the two resources has a corresponding relationship in resource position, or each first resource among the plurality of first resources has a corresponding relationship with each second resource among the plurality of second resources. . For example, with a single time slot as the granularity, in the same time slot, there is one first resource, which occupies the time-domain symbol with index 13. The number of the second resources is two, and the occupied time-domain symbol indices include: 4, 5, 6, 7, 8, 9, 10, and 11. There is a corresponding relationship between one first resource and two second resources in the time slot in the time domain symbols. For example, the first resource and the first second resource are separated by 9 time domain symbols in the time domain. The second second resources are separated by 5 time domain symbols in the time domain. For another example, with a single time slot as the granularity, in the same time slot, there are two first resources, and the occupied time domain symbol indexes include 3 and 13. The quantity of the second resource is two, and the occupied time domain symbol indexes include: 4 to 11. In this time slot, there is a corresponding relationship between each first resource and each second resource in the time domain symbol, for example, the first first resource and the first second resource are continuous in the time domain, and the first first resource The interval between the second first resource and the first second resource is 5 time domain symbols in the time domain, the interval between the second first resource and the first second resource is 9 time domain symbols in the time domain, the second first resource and the second The second resources are separated by 4 time domain symbols in the time domain. For another example, taking two consecutive time slots as a granularity, in the two consecutive time slots, the number of first resources is three, and the occupied time-domain symbol indexes include 3, 13, and 24. The number of the second resources is four, and the occupied time domain symbol indexes include: 4 to 11, and 16 to 23. In this time slot, there is a corresponding relationship between each first resource and each second resource in the time domain symbols. For example, the positional relationship between the first first resource and the four second resources in the time domain is as follows: The domains are continuous, the interval is 5 time domain symbols, the interval is 13 time domain symbols, and the interval is 20 time domain symbols. The positional relationship between the second first resource and the four second resources in the time domain is as follows: Domain symbols, intervals of 5 time domain symbols, intervals of 3 time domain symbols, intervals of 7 time domain symbols, the positional relationship between the third first resource and the four second resources in the time domain is as follows: interval 20 hours Domain symbols, intervals of 16 time domain symbols, intervals of 8 time domain symbols, time domain continuous. In this embodiment of the present application, the interval between two resources refers to a difference determined based on the indexes of the two resources. For example, in the same time slot, the index of the time domain symbol occupied by resource 1 is 1, and the index of the time domain symbol occupied by resource 2 is 6, then the interval between resource 1 and resource 2 is 5 time domain symbols. It should be understood that the interval between two resources may also be equivalently replaced by the number of time-domain resource units located between the two resources, but the value differs by 1. Still taking resource 1 and resource 2 as an example, the number of time-domain symbols located between resource 1 and resource 2 is four. In addition, the above at least one first signal may also be described as a first signal as a whole. There is at least one first resource, and each first resource in the at least one first resource carries a signal, and the signal carried on each first resource is described as a sub-signal. That is, the first signal includes at least one sub-signal. For convenience of description, in this embodiment of the application, the network device is the network device 301 and the terminal device is the terminal device 305 as an example for introduction. The description is unified here, and will not be described in detail below.

An embodiment of the present application provides a signal transmission method 400, and the signal transmission method 400 is applied in a signal transmission process of radar communication integration. Referring to Fig. 4, this method comprises the steps:

S401. The network device 301 determines a first resource.

Wherein, the first resource and the second resource do not overlap in the time domain. There are one or more first resources, and any two adjacent first resources among the multiple first resources may or may not be continuous in the time domain. Each first resource may be a time domain symbol. Specifically, the network device 301 may determine one or more first resources. It can be understood that the first resource and the second resource do not overlap in the time domain. When the number of the first resource and the number of the second resource are both multiple, any one of the multiple first resources and multiple Any second resource among the second resources does not overlap in the time domain.

Wherein, each second resource may be four consecutive time domain symbols in the time domain, and refer to the related description of FIG. 1 for details. The number of second resources can be multiple. Among the multiple second resources, any two adjacent second resources can be continuous in the time domain, as shown in the time domain resource and index occupied by the SSB with index 0 in Figure 2a The time domain resources occupied by the SSB with index 1 are continuous, and the time domain resources occupied by the SSB with index 2 and the time domain resources occupied by the SSB with index 3 are continuous. Any two second resources may also be discontinuous, as shown in Figure 2a, the time domain resource occupied by the SSB with index 1 and the time domain resource occupied by the SSB with index 2 are discontinuous, and as shown in Figure 2b, the index is The time domain resource occupied by the SSB with index 0 and the time domain resource occupied by the SSB with index 1 are discontinuous.

Wherein, the specific implementation manners of S401 include the following two types:

As a first implementation manner, the first resource is determined based on the second resource. That is to say, when the resource position of the second resource remains unchanged, the resource position of the first signal is adjusted to obtain the first resource, so that the first resource and the second resource do not overlap in the time domain. Wherein, the second resource is a resource for sending the SSB signal determined from the candidate positions of the SSB signal. Exemplarily, when the third resource overlaps with the candidate position of the SSB signal, the first resource does not include the resource overlapping with the candidate position of the SSB signal in the third resource. Below, three examples are introduced:

As an example 1 of the first implementation manner, in a case where the resource location density of the second resource is high, the first signal is still transmitted at equal intervals within the target duration. Wherein, the target duration is formed by at least one time slot where the second resource is located. Taking the second resource belonging to the resource location specified in 3GPP TS 38.213 as an example, the target duration is one half frame, which is 5ms. The resource location density of the second resource is relatively high, which may mean that the number of SSB signals is less than or equal to 64, that is, it may be understood that the number of SSB signals included in one SSB burst (burst) is less than or equal to 64. For example, in the protocol 3GPP TS 38.213, when the subcarrier spacing of the subcarriers transmitting the SSB signal is 120kHz, the maximum number of candidate positions for the SSB signal can be 64, that is, in the formula (4), the number of n values reaches the maximum , for 16. When the candidate positions of the SSB signals are full, the number of SSB signals is 64, that is, 64 SSB signals are sent within 5 ms.

That is to say, within the target duration, the intervals between any two adjacent first signals are the same. In other words, within the target duration, when the interval between two adjacent first signals in the above-mentioned at least one first signal is recorded as the first interval, there are multiple first intervals, and the time of multiple first intervals same length. Wherein, there are multiple first intervals, which means that the network device 301 transmits multiple first signals within the target duration, and there is a first interval between every two adjacent first signals. Thus, the number of first intervals is plural.

Exemplarily, within the target duration, the first resource includes a time-domain resource unit whose index value is a first preset value. Taking the time-domain resource unit as the time-domain symbol as an example, when the subcarrier interval for transmitting the SSB signal is 120kHz, with a single time slot as the granularity, the indexes of the time-domain symbols that are not occupied by the second resource are as follows: 0, 1, 12, and 13. Therefore, the first preset value includes one of the following: 0, 1, 12, or 13. That is, the first resource occupies one of the time-domain symbols 0, 1, 12, or 13 in the time slot within the target duration, and does not overlap with the second resource in the time domain, thereby avoiding collisions between the first signal and the SSB signal. Specifically, the first preset value can be one of 0, 1, 12, 13, {0, 1}, {12, 13}, where {0, 1} means that the time-domain symbol 0 and the time-domain symbol are occupied at the same time domain symbol 1. It should be understood that, taking the subcarrier spacing of the SSB signal as 120kHz as an example, within the target duration (5ms), when the network device 301 transmits the first signal on the time domain symbol 12 in each time slot, there are 40 One interval, and each first interval is 1 time slot (that is, 14 symbols). Within the target duration (5 ms), when the network device 301 transmits the first signal on time-domain symbol 0 and time-domain symbol 1 in each time slot, there are 40 first intervals, and each first interval is are 13 time-domain symbols.

For example, refer to Fig. 5a, which shows a schematic diagram of resource distribution. The resource location of the second resource is determined based on condition D of 3GPP TS 38.213. When the number of SSB signals is 64, that is, the SSB signals occupy all the candidate positions of SSB in the field. In the half frame, the time-domain symbol index of the first resource is 13, that is, there are multiple first resources, and the time-domain symbol with index 13 on each time slot in the first 5 ms. That is to say, the network device 301 transmits the first signal on time-domain symbols 13 in each time slot within 5 ms. Taking two consecutive time slots as the granularity, the time-domain symbol indexes that the second resource always occupies are as follows: 4, 5, 6, 7, 8, 9, 10, 11, 16, 17, 18, 19, 20, 21, 22, 23. In this way, any one of the multiple first resources does not overlap with any one of the multiple second resources in the time domain. Moreover, when there is a first interval between every two adjacent first signals, the time length of each first interval is the same.

It should be understood that still taking the time-domain resource unit as the time-domain symbol as an example, in the case that the subcarrier interval for transmitting the SSB signal is 120kHz, if two adjacent time slots are used as the granularity, the resource position of the second resource is always different. The occupied time-domain symbol indices are as follows: 0, 1, 2, 3, 12, 13, 14, 15, 24, 25, 26, 27. Therefore, in every two first preset values, one first preset value includes one of the following: 0, 1, 2, 3, 12, 13, and the other first preset value includes one of the following: 14, 15, 24, 25, 26, 27. In this way, any first resource among the plurality of first resources does not overlap with any second resource among the plurality of second resources in the time domain, thereby avoiding collision between the first signal and the SSB signal. In the case of two adjacent time slots as the granularity, the first signal can be transmitted at equal intervals within the target duration, for example, the two first preset values are 0 and 14, 1 and 15, 12 and 26, and 13 and 27, {0 and 1, 14 and 15}, {12 and 13, 26 and 27}, the first interval between two adjacent first signals is 1 time slot. The first signal may not be transmitted at equal intervals within the target duration, for example, the two first preset values are 0 and 15, 1 and 14, 12 and 27, 13 and 26, {0 and 1, 24 and 25} , {12 and 13, 25 and 26}, the first interval between two adjacent first signals is not the same, that is, the transmission of the first signal is not at equal intervals, but the network device 301 in One first signal can be transmitted in each time slot without colliding with the SSB signal.

As an example 2 of the first implementation manner, in a case where the resource location density of the second resource is high, the first signal can still maintain a high time-domain density within the target duration. Wherein, the introduction of the target duration can refer to the relevant description of the first example above, and will not be repeated here.

In this case, within the target duration, the intervals between two adjacent first signals are not all the same, that is, there are at least "the interval between two adjacent first signals" and "the interval between the other two adjacent first signals" The interval between the first signals" is different. In other words, within the target duration, there are multiple first intervals, and time lengths of at least two first intervals among the multiple first intervals are different. Wherein, "the first interval is multiple" can refer to the relevant description of the above example 1, which will not be repeated here. For example, with two time slots as the granularity, within the target duration (5 ms), when the network device 301 respectively transmits the first signal on the time domain symbols 3, 13 and 24, there are three first intervals of length, namely The first interval between domain symbol 3 and time domain symbol 13 is 10 time domain symbols, the first interval between time domain symbol 13 and time domain symbol 24 is 11 time domain symbols, time domain symbol 24 and the next The first interval between time domain symbols 3 in a slot is 7 time domain symbols.

Exemplarily, within the target duration, the first resource includes a time-domain resource unit whose index value is a second preset value. Taking the time-domain resource unit as a time-domain symbol as an example, in the case that the subcarrier interval for transmitting SSB signals is 120kHz, and taking two consecutive time slots as the granularity, the resource position of the second resource is always not occupied by the time-domain symbol index as follows : 0, 1, 2, 3, 12, 13, 14, 15, 24, 25, 26, and 27. Based on this, the value of the second preset value includes the following two possible designs:

In a first possible design, the second preset value includes at least three of the following: 0, 1, 2, 3, 12, 13, 14, 15, 24, 25, 26, or 27. Wherein, the difference between any two items in the second preset value is greater than or equal to the third preset value. Exemplarily, the value of the third preset value may be 6. In this case, the value of the second preset value may refer to the second possible design, so that there is at least one first The resource, that is, the network device 301 transmits at least one first signal in each time slot. Moreover, the difference between any two items in the second preset value is greater than or equal to the third preset value, which also makes the first resource non-continuous in the time domain, and ensures that the first resource is not continuous in the time domain to a certain extent. The distribution over the domain is uniform. The value of the second preset value is at least three items, that is, there are at least three first resources in every two time slots, so that the network device 301 transmits at least three first signals in every two time slots. In the half frame of Example 1, there is one first resource in each time slot, that is, one first signal is transmitted in each time slot. Compared with Example 1, Example 2 increases the time-domain density of the first signal, which is beneficial to improving radar detection accuracy. Of course, the value of the third preset value can also be other values, for example, the value of the third preset value can be 1, and the second preset value can be {0, 2, 14}, {0, 2, 15 }, {0, 3, 24}, {0, 3, 27}, {12, 15, 25}, {12, 15, 27}, {12, 24, 27}, {15, 24, 27} of an item. That is to say, the network device 301 may transmit the two first signals on the resource between the two SSB signals, or the network device 301 may not transmit the first signal on the resource between the two SSB signals. However, the network device 301 can always transmit three first signals in two time slots, so as to increase the time-domain density of the first signals.

In a second possible design, the number of second preset values is three. Wherein, the three second preset values satisfy:

The first second preset value includes one of the following: 0, 1, 2, or 3.

The second second preset value includes one of the following: 12, 13, 14, or 15.

The third second preset value includes one of the following: 24, 25, 26, or 27.

In other words, on two adjacent time slots, the network device 301 transmits one first signal on resources between two SSB signals, and the network device 301 can always transmit three first signals on two time slots. Exemplarily, the second preset value may be one of the following: {0, 12, 24}, {1, 13, 25}, {2, 14, 26}, {3, 15, 27}, {0 , 13, 24}, {1, 13, 24}, {2, 14, 24}, {3, 13, 27}, {0, 15, 24}, {1, 15, 24}, {2, 15 , 24}, or {3, 15, 27}. Taking the second preset value including {0, 12, 24} as an example, the network device 301 respectively transmits the first signal on symbols 0, 12 and 24 in the time domain.

That is to say, the difference between the second preset values is relatively uniform. Correspondingly, the distribution of the time-domain symbols indexed by the second preset value on the time slot is relatively uniform, so that the first signal is transmitted as uniformly as possible in the time domain, which not only ensures the timing of the first signal The domain density avoids collision with SSB signal.

Alternatively, the method provided in Example 2 of the first implementation method can also be understood as: when some resources in the third resource overlap with candidate positions of the SSB signal, the first resource includes at least: combining the third resource with the SSB signal The overlapping resources of the candidate positions of the signals advance or delay the resources after at least one time-domain symbol, so as to prevent the network device 301 from transmitting the first signal and the SSB signal at the same time, and at the same time ensure that the first resources are evenly distributed as much as possible to ensure that the radar Detection accuracy. For example, taking Fig. 5b as an example, according to the transmission period of the first signal, the third resource includes time domain symbol 6. But the time domain symbol 6 is used to carry the SSB signal, so the third resource "time domain symbol 6" is moved forward, as shown by the time domain symbol 3 in Figure 5b, and the time domain symbol 3 is used to transmit the first signal . For another example, still taking FIG. 5b as an example, according to the transmission period of the first signal, the third resource includes a time-domain symbol 20 . However, the time domain symbol 20 still bears the SSB signal, so the third resource "time domain symbol 20" is shifted backward, as shown by the time domain symbol 24 in Figure 5b, and the time domain symbol 24 is used to transmit the first signal . It should be understood that in the scenario shown in FIG. 5 b , the third resource includes time domain symbols 27 . However, after the forward and backward shifts are performed, both the time-domain symbol 3 and the time-domain symbol 24 are used to transmit the first signal, and the time-domain symbol 27 can no longer be used to transmit the first signal, so as to avoid frequent transmission of the first signal and save transmission resources, and close to the original transmission period of the first signal. Certainly, the time-domain symbol 27 may also be used to transmit the first signal, so as to reduce the computation load of the network device, which is not limited in this embodiment of the present application.

For example, refer to Fig. 5b, which shows a schematic diagram of resource distribution. The resource location of the second resource is determined based on condition D of 3GPP TS 38.213. In the case where the number of SSB signals is 64, within a half frame, the time-domain symbol indexes of the first resource include 3, 13, and 24, which neither collides with the SSB signal nor ensures that the first signal is transmitted as uniformly as possible .

As an example 3 of the first implementation manner, in a case where the resource location density of the second resource is low, the SSB signal only occupies part of the candidate locations. In the case where the subcarrier spacing of the transmitted SSB signal is 120kHz, the time-domain symbol index of the SSB signal satisfies:

{4, 16}+28*n formula (6)

Wherein, n=0, 1, 2, 3, 5, 6, 7, 8, 10, 11, 12, 13, 15, 16, 17, 18.

Wherein, the resource location density of the second resource is low, which may mean that the number of SSB signals is less than or equal to 32, that is, it can be understood that the number of SSB signals included in one SSB burst is less than or equal to 32, that is, candidates for SSB signals A maximum of 32 positions can be supported, that is, in formula (6), the maximum number of values of n is 16. When the candidate positions of the SSB signals are full, the number of SSB signals is 32, that is, 32 SSB signals are sent within 5 ms.

In this case, within the target duration, the intervals between two adjacent first signals are not all the same. For details, refer to the description of the above-mentioned example 2, which will not be repeated here. Exemplarily, within the target duration, the first resource includes a time-domain resource unit whose index value is a second preset value. Taking the time-domain resource unit as the time-domain symbol as an example, and taking two consecutive time slots as the granularity, the second preset value satisfies the following formula:

K＝7*k-1 formula (7)

Wherein, K represents the second preset value, and K=2, 3, 4. That is, the values of the second preset value include 13, 20, and 27. Combining formula (6) and formula (7), it can be known that with two adjacent time slots as the granularity, the time domain symbol indexes of the second resource are: 4, 5, 6, 7, 16, 17, 18, 19. The time domain symbol indexes of the first resource are: 13, 20, 27. That is, according to the transmission period of the first signal, the time-domain symbol 6 is used to transmit the first signal. However, time domain symbol 6 is used to transmit the SSB signal, so time domain symbol 6 is no longer used to transmit the first signal. That is to say, within the target duration, the third resource that conflicts with the second resource is no longer used to transmit the first signal. In other words, within the target duration, the first resource is composed of resources that do not overlap with candidate positions of the SSB signal among the third resources.

For example, refer to FIG. 5c, which shows a schematic diagram of resource distribution. The resource location of the second resource is determined based on the above formula (6). In the case that the number of SSB signals is less than or equal to 32, within a half frame, the time-domain symbol indexes of the first resource include 13, 20, and 27 at the granularity of two consecutive time slots.

That is to say, taking the transmission period of the first signal as an example of 7 time-domain symbols, when the transmission position of the first signal overlaps with the transmission position of the SSB signal (that is, the second resource), the first signal is discarded, The network device 301 does not transmit the first signal, that is, the value of the second preset value does not include 6, so as to avoid collision between the first signal and the SSB signal, and ensure the time domain density of the first signal.

It should be noted that, outside the target duration of the first implementation manner, the SSB signal is not sent any more. In other words, there is no secondary resource other than the target duration. The first signal may maintain an original transmission period. That is to say, the time interval between two adjacent first signals within the target duration is different from the time interval between two adjacent first signals outside the target duration. In addition to the target duration, when the interval between two adjacent first signals in the above-mentioned at least one first signal is recorded as the second interval, there are multiple second intervals, and the time lengths of the multiple second intervals are the same , but is different from the time length of the first interval, and when there are multiple first intervals, the second interval is different from at least one of the first intervals. Wherein, there are multiple second intervals, which means that the network device 301 transmits multiple first signals outside the target duration, and there is a second interval between every two adjacent first signals. Thus, the number of second intervals is plural. Outside the target duration, the first resource includes a time-domain resource unit whose index value is a preset value of 1. In the case that the time-domain resource unit is a time-domain symbol, the value of the preset value 1 may include: 6, 13, as shown in Fig. 5a, Fig. 5b and Fig. 5c for details.

It should be understood that in this embodiment of the present application, the transmission period of the first signal is 7 symbols as an example. In the case that the transmission period of the first signal is other time lengths, the first resource The resource locations may also be designed according to other intervals to meet the transmission requirements of the first signal in different scenarios, which is not limited in this embodiment of the present application.

As a second implementation manner, the second resource is determined based on the first resource. That is to say, when the transmission period of the first signal remains unchanged, the candidate positions of the SSB signal are adjusted to obtain the second resource, so that the first resource and the second resource do not overlap in time domain. Below, two examples are introduced:

As an example 1 of the second implementation manner, in a case where the resource location density of the second resource is low, the SSB signal only occupies part of the candidate locations. In the case that the subcarrier interval for transmitting SSB signals is 120kHz, the second resource is introduced through two possible designs:

In a first possible design, within the target duration, the second resource includes a time-domain resource unit whose index value is a fourth preset value, and the fourth preset value satisfies the following formula:

Wherein, M represents the fourth preset value, N is an integer, and 0≤N≤27, and k is a positive integer.

It can be seen from the formula (8) that when the transmission period of the first signal is 7 time-domain symbols, the time-domain symbol index of the first resource satisfies: 7*k-1. In the process of N traversing 28 integers (from 0 to 27), the time-domain symbol index carrying the SSB signal is not equal to the time-domain symbol index of the first resource, so as to avoid the overlap between the first resource and the second resource in the time domain .

Exemplarily, with two adjacent time slots as the granularity, the time-domain symbol indexes of the first resource include: 6, 13, 20, and 27. For example, in the case of N=0, the time-domain symbol indexes of the second resource include: 0, 1, 2, 3, none of which are equal to the time-domain symbol indexes of the first resource, so the time-domain symbols {0, 1, 2, 3} may be used as the second resource for sending the SSB signal. For another example, in the case of N=3, the time-domain symbol indexes of the second resource include: 3, 4, 5, and 6. In this case, there is a value "6" in the time-domain symbol index of the second resource that is equal to the time-domain symbol index of the first resource, so the time-domain symbols {3, 4, 5, 6} cannot be used as the second resource , not used to send SSB signals.

It should be understood that in the first possible design, only the transmission period of the first signal is 7 time-domain symbols as an example for introduction. The transmission period of is T time-domain symbols, the above formula (8) can be replaced by:

Wherein, M represents the fourth preset value, T is the transmission period of the first signal, N is an integer, and 0≤N≤27, and k is a positive integer. That is to say, when the transmission period of the first signal is T time-domain symbols, the time-domain symbol index of the first resource satisfies: T*k-1. During the process of N traversing 28 integers (ie from 0 to 27), the time-domain symbol index carrying the SSB signal is not equal to the time-domain symbol index of the first resource, that is, the time-domain symbol index of the second resource (ie, the second resource The value of the time-domain symbol index M, M+1, M+2, M+3) is not equal to the value of the time-domain symbol index of the first resource, so as to avoid overlapping of the first resource and the second resource in the time domain.

Exemplarily, taking two adjacent time slots as a granularity, taking T=8 as an example, the time-domain symbol indexes of the first resource include: 7, 15, and 23. For example, in the case of N=0, the time-domain symbol indexes of the second resource include: 0, 1, 2, 3, none of which are equal to the time-domain symbol indexes of the first resource, so the time-domain symbols {0, 1, 2, 3} may be used as the second resource for sending the SSB signal. For another example, in the case of N=4, the time-domain symbol indexes of the second resource include: 4, 5, 6, and 7. In this case, there is a value "7" in the time-domain symbol index of the second resource that is equal to the time-domain symbol index of the first resource, so the time-domain symbols {4, 5, 6, 7} cannot be used as the second resource , not used to send SSB signals.

In the second possible design, within the target duration, the second resource includes a time-domain resource unit whose index value is a fourth preset value, and the fourth preset value satisfies the following formula:

Wherein, M represents the fourth preset value, and N includes at least two of the following values: 0, 1, 2, 7, 8, 9, 14, 15, 16, 21, 22, or 23. It can be seen from the introduction of FIG. 1 that one SSB signal occupies four symbols in the time domain. Therefore, the difference between any two items in the fourth preset value is greater than 4, so as to avoid overlapping resources occupied by SSB signals. Exemplarily, the fourth preset value may be one of the following: {0, 7}, {0, 8}, {0, 9}, {0, 22}, {1, 7}, {1, 8} , {1, 9}, {1, 22}, {1, 23}, {1, 8, 16}, or {2, 9, 16}. It should be understood that, in the case where the difference between any two items in the fourth preset value is greater than 4, the value of the fourth preset value only needs to be taken from the above-mentioned values (ie 0, 1, 2, 7, 8, 9, 14, 15, 16, 21, 22, or 23) will suffice.

For example, refer to Fig. 5d, which shows a schematic diagram of resource distribution. Taking two time slots as the granularity, when N includes 8 and 16, the resource position of the second resource (that is, the position carrying the SSB signal) includes time domain symbols 8, 9, 10, 11, 16, 17, 18, 19, as shown in FIG. 5d , neither overlaps with any resource in the first resource. In this way, the first signal transmitted by the network device 301 does not collide with the SSB signal.

As an example 2 of the second implementation manner, in a case where the resource position density of the second resource is high, the SSB signal occupies all candidate positions in the field. In the case where the subcarrier spacing of the transmitted SSB signal is 120kHz, the time-domain symbol index of the SSB signal satisfies:

{2, 8, 16, 22}+28*n formula (11)

Wherein, n=0, 1, 2, 3, 5, 6, 7, 8, 10, 11, 12, 13, 15, 16, 17, 18.

Exemplarily, in FIG. 5e , in the case of n=0, the SSB signal identified by the index 0 is the first SSB signal in the field, and the indices of the occupied time domain symbols are 2 to 5. The SSB signal identified by index 1 is the second SSB signal in the field, and the indices of the symbols in the time domain occupied are 8 to 11. The SSB signal identified by index 2 is the third SSB signal in the half-frame, and the indices of the occupied time domain symbols are 16 to 19. The SSB signal identified by index 3 is the fourth SSB signal in the field, and the indices of the symbols in the time domain occupied are 22 to 25.

That is to say, with two adjacent time slots as the granularity, when the transmission period of the first signal is 7 time-domain symbols, the time-domain symbol indexes of the first resource include: 6, 13, 20, and 27. For example, combined with formula (4), in the case that the first time domain symbol index is 4, the time domain symbol index of the second resource includes: 4, 5, 6, 7, that is, the values in the time domain symbol index of the second resource "6" is equal to the time-domain symbol index of the first resource, that is, it overlaps with the first resource, so "4" is adjusted to "2", as shown in formula (11), so, the first time-domain symbol index 2 The second resource includes: time-domain symbol 2, time-domain symbol 3, time-domain symbol 4, and time-domain symbol 5, and does not overlap with the first resource. For another example, in combination with formula (4), in the case where the first time-domain symbol index is 20, the time-domain symbol indexes of the second resource include: 20, 21, 22, 23, that is, in the time-domain symbol indexes of the second resource The value "20" is equal to the time-domain symbol index of the first resource, that is, it overlaps with the first resource, so adjust "20" to "22", as shown in formula (11), so that the first time-domain symbol index 22 The second resource includes: time-domain symbol 22, time-domain symbol 23, time-domain symbol 24, and time-domain symbol 25, which do not overlap with the first resource.

It should be noted that, in the second implementation manner, no matter within the target duration or outside the target duration, the first signal maintains the original transmission period, that is, the time length of the first interval is the same as that of the second interval. When the number of the first interval and the second interval is plural, each of the plurality of second intervals is the same as each of the plurality of first intervals. Wherein, the target duration is constituted by at least one time slot where the candidate position of the SSB signal is located. For the first interval and the second interval, reference may be made to the introduction of the first implementation manner, and details are not repeated here. In the second implementation manner, the first resource includes a time-domain resource unit whose index value is a preset value of 1. In the case that the time-domain resource unit is a time-domain symbol, the value of the preset value 1 may include: 6, 13, as shown in FIG. 5d.

S402. The network device 301 transmits at least one first signal on the first resource.

Wherein, the network device 301 has a sensing function, and the first signal is used to detect the attribute of the target. The attribute of the target includes at least one of the following: moving speed, position, or shape and size. Exemplarily, if the terminal device 305 is in the detection area of the first signal, and the radar cross-section (radar cross-section, RCS) is greater than the threshold, the target detected by the first signal includes the terminal device 305, and the network device 301 can receive The echo signal reflected by the terminal device 305 is received, so as to perceive attributes such as the position of the terminal device 305 . Conversely, if the terminal device 305 is outside the detection area of the first signal, or the RCS is less than or equal to the threshold, the network device 301 cannot receive the echo signal reflected by the terminal device 305, that is, the sensing object of the network device 301 does not include the terminal device 305, it is impossible to detect attributes such as the location of the terminal device 305. Of course, in addition to the above-mentioned terminal device 305, the target can also be other objects that reflect the echo signal, and the network device 301 can perceive the attribute of the target after receiving the echo signal.

Wherein, the first resource in S402 is the first resource in S401. The first resource in S402 can be determined based on the second resource, refer to the introduction of the first implementation in S401, the first resource in S402 can also be used to determine the second resource, refer to the second implementation in S402 introduction, and will not be repeated here. Each first resource carries a first signal. In a case where there is one first resource, the network device 301 transmits one first signal on the first resource. In a case where there are multiple first resources, the network device 301 transmits a first signal on each first resource of the multiple first resources.

Exemplarily, the specific implementation process of S402 includes:

Example 1, the network device 301 sends at least one first signal on the first resource, for example, in the case of one first resource, the network device 301 sends one first signal on the first resource. In a case where there are multiple first resources, the network device 301 sends a first signal on each first resource of the multiple first resources. In this case, the first signal can be implemented as a radar detection signal.

Example 2, the network device 301 receives at least one first signal on the first resource, for example, in the case of one first resource, the network device 301 receives one first signal on the first resource. In a case where there are multiple first resources, the network device 301 receives a first signal on each first resource of the multiple first resources. In this case, the first signal can be implemented as an echo signal of the radar detection signal.

Example 3, the network device 301 sends and receives the first signal on the first resource, for example, in the case of one first resource, the network device 301 sends and receives the first signal on the first resource. In the case that there are multiple first resources, the network device 301 sends and receives the first signal on each first resource of the multiple first resources. In this case, the transmitted first signal may be implemented as a radar detection signal, and the received first signal may be implemented as an echo signal of the radar detection signal.

Example 4, when there are multiple first resources, divide the multiple first resources into two parts, and the network device executes one of the above three examples (Example 1-Example 3) on a part of the first resources, The network device executes another one of the above three examples (Example 1 to Example 3) on another part of the first resource. Alternatively, the multiple first resources are divided into three parts, and the network device executes one of the above three examples (Example 1 to Example 3) on each part of the first resources.

Exemplarily, S402 is introduced in two situations:

As a first case, the first signal carries communication information. Referring to Figure 6a, before executing S402, the network device 301 executes S403:

S403. The network device 301 sends the first indication information to the terminal device 305. Correspondingly, the terminal device 305 receives the first indication information from the network device 301 .

Wherein, the first indication information indicates the index value of the first resource.

Exemplarily, the first indication information may carry an index value of the first resource. For example, in the case of a granularity of a single time slot, the first indication information may be an index value indicating the first resource by using 4 bits. For another example, in the case where two time slots are used as the granularity, the first indication information may indicate the index value of the first resource by using 5 bits. For the index value of the first resource, reference may be made to the related introduction of S401, which will not be repeated here.

Alternatively, the first indication information may also indicate an offset between the first resource and the second resource. Wherein, the unit of the offset is a time-domain symbol, and the value of the offset indicates the number of time-domain symbols separated between the first resource and the second resource. The offset can be represented by a preset number of bits. For example, if the offset is small, such as less than 8 time-domain symbols, the first indication information may use 3 bits to indicate the offset. For another example, if the offset is relatively large, for example, more than 8 time-domain symbols, the first indication information may use 4 or 5 bits to indicate the offset.

Exemplarily, the first indication information may be high-layer signaling, such as radio resource control (radio resource control, RRC) signaling, or the first indication information may also be physical layer signaling, such as downlink control information (downlink control information, DCI).

When S403 is executed, S402 is specifically implemented as S402a:

S402a. The network device 301 sends communication information to the terminal device 305 on the first resource. Correspondingly, the terminal device 305 receives the communication information from the network device 301 on the first resource.

Wherein, the communication information is carried in the first signal. The communication information includes but is not limited to: a physical downlink shared channel (physical downlink shared channel, PDSCH) and the like. The terminal device 305 obtains the communication information from the first signal through processing such as demodulation and decoding.

As a second case, no communication information is carried on the first signal. In this case, the network device 301 does not need to execute S403 before executing S402. That is, it is enough for the network device 301 to transmit the first signal according to the resource location of the first resource.

For the network device 301, the network device 301 can also send the SSB signal, as shown in the steps shown in Figure 6b:

S404. The network device 301 sends at least one SSB signal to the terminal device 305 on the second resource. Correspondingly, the terminal device 305 may receive at least one SSB signal from the network device 301 on the second resource.

Wherein, the second resource in S404 is the second resource in S401. The second resource in S404 can be used to determine the first resource, refer to the introduction of the first implementation in S401, the second resource in S404 can also be determined based on the first resource, refer to the second implementation in S402 introduction, and will not be repeated here. Each second resource carries one SSB signal. In the case that there is one second resource, the network device 301 sends one SSB signal on the second resource. In a case where there are multiple second resources, the network device 301 sends one SSB signal on each second resource of the multiple second resources.

Exemplarily, S404 is introduced in two situations:

As the first case, the second resource is determined based on the first resource. For details, refer to the introduction of the second implementation manner in S401. Referring to Figure 6b, before executing S404, the network device 301 executes S405:

S405. The network device 301 sends the second indication information to the terminal device 305. Correspondingly, the terminal device 305 receives the second indication information from the network device 301 .

Wherein, the second indication information indicates the index value of the second resource.

Exemplarily, the second indication information may carry an index value of the second resource. For example, in the case of a granularity of a single time slot, the second indication information may be an index value indicating the second resource by using 4 bits. For another example, in the case of using two time slots as the granularity, the second indication information may indicate the index value of the second resource by using 5 bits. For the index value of the second resource, refer to the relevant introduction of S401, and details will not be repeated here.

Alternatively, the second indication information may also indicate an offset between the second resource and the candidate position of the SSB signal. Wherein, the unit of the offset is a time-domain symbol, and the value of the offset indicates the number of time-domain symbols separated between the second resource and the candidate position of the SSB signal. The offset can be represented by a preset number of bits. For example, if the offset is small, such as less than 8 time-domain symbols, the second indication information may use 3 bits to indicate the offset. For another example, if the offset is large, for example, more than 8 time-domain symbols, the second indication information may use 4 or 5 bits to indicate the offset.

Exemplarily, the second indication information may be high-layer signaling, such as signaling, or the second indication information may also be physical layer signaling, such as DCI.

That is to say, when the resource location of the first resource remains unchanged and the second resource is determined based on the first resource, the network device 301 first indicates the index value of the second resource to the terminal device 305 so that the terminal device 305 The SSB signal is received at the resource position indicated by the second indication information.

It should be noted that the network device 301 sends the SSB signal to the terminal device 305 on a known resource within a preset time period (for example, n seconds) before the terminal device 305 executes S405. Correspondingly, the terminal device 305 receives the SSB signal from the network device 301 on known resources. Wherein, the known resources are resources specified based on existing protocols (such as 3GPP TS 38.213). In this way, the terminal device 305 realizes synchronization with the network device 301 through the SSB signal within the preset duration, and then the terminal device 305 executes S405. In addition, the network device 301 may not perform S405. In this case, the terminal device 305 performs blind detection, that is, scans each time-domain symbol. If the SSB signal is transmitted on some time-domain symbols, the terminal device 305 can detect the SSB signal from the network device 301 .

As the second case, the second resource is used to determine the first resource. For details, refer to the introduction of the first implementation manner in S401. In this case, the network device 301 does not need to execute S405 before executing S404.

It should be noted that after the network device 301 sends the indication information (such as the first indication information and the second indication information) to the terminal device 305, if the terminal device 305 receives the indication information, the terminal device 305 may send the indication information to the network device 301. Acknowledgment (ACK). On the contrary, if the terminal device 305 does not receive the indication information, the terminal device 305 sends a negative acknowledgment (negative acknowledgment, NACK) to the network device 301 . In addition, in the half frame in which the SSB signal is transmitted, the distribution status of the first resource is consistent. Even in the half-frame where the SSB signal is transmitted, some time slots include candidate positions of SSB signals, and other part of time slots do not include candidate positions of SSB signals, the distribution status of the first resource in the two time slots is still consistent , the network device 301 always transmits the first signal in a fixed pattern, avoiding frequent changes of resource locations of the first signal, and also simplifying the complexity of determining the first resource by the network device 301 .

It can be understood that the methods shown in FIG. 6a and FIG. 6b can be implemented individually or in combination. This application is not limited to this.

All of the above are introduced by taking the example that the first resource and the second resource do not overlap in the time domain, so as to avoid mutual interference between signals. Certainly, in the case that the first resource and the second resource overlap in the time domain, mutual interference between signals can also be avoided if the first resource and the second resource do not overlap in the frequency domain. The embodiment of the present application also provides another signal transmission method. The technical idea of the signal transmission method is as follows: the network device determines the first resource. Wherein, the first resource and the second resource overlap in the time domain and do not overlap in the frequency domain, and the second resource is used for sending communication signals. There is a corresponding relationship between the first resource and the second resource. Then, the network device transmits at least one first signal on the first resource. In this way, the first signal and the communication signal are transmitted by means of frequency division multiplexing, so that the first signal and the communication signal do not collide and interfere with each other, thereby improving the communication efficiency of the system.

Wherein, there is a corresponding relationship between the first resource and the second resource, which may mean that, in the preset number of frequency domain resource units, there is a corresponding relationship between the first resource and the second resource in resource positions, for example, the first resource and the second resource The two resources have the same quantity and correspond one-to-one. Or, the quantity of the first resource is different from the quantity of the second resource, and one first resource among the multiple first resources corresponds to one second resource among the multiple second resources. For example, taking the frequency domain resource unit as an RB as an example, in the same system bandwidth, there are multiple first resources, and each first resource occupies _an RB whose index is x1. There are multiple second resources, and each second resource occupies _an RB whose index is a1. Among them, x ₁ <a ₁ . x ₁ is the index of X RBs with the smallest frequency in the system bandwidth, and X is a positive integer. Taking the communication signal as an SSB signal as an example, it can be seen from FIG. 1 that one SSB signal occupies 20 RBs. x ₁ <a ₁ , it can be understood that the RB index corresponding to the first resource is smaller than the index of each RB in the 20 RBs corresponding to the second resource. For another example, still taking the frequency domain resource unit as an RB as an example, in the same system bandwidth, there are multiple first resources, and each first resource occupies an RB whose index is _y1 . There are multiple second resources, and each second resource occupies _an RB whose index is a1. Among them, a ₁ <y ₁ . y ₁ is the index of Y RBs with the highest frequency in the system bandwidth, and Y is a positive integer. Taking the communication signal as an SSB signal as an example, it can be seen from FIG. 1 that one SSB signal occupies 20 RBs. a ₁ <y ₁ , it can be understood that the RB index corresponding to the first resource is greater than the index of each RB in the 20 RBs corresponding to the second resource. For the description of the first signal, reference may be made to the introduction of the signal transmission method 400, and details are not repeated here.

As shown in FIG. 7 , an embodiment of the present application provides a signal transmission method 700 , and the signal transmission method 700 is applied in a signal transmission process of radar communication integration. Referring to Fig. 7, this method comprises the steps:

S701. The network device 301 determines a first resource.

Wherein, the first resource and the second resource overlap in the time domain, but do not overlap in the frequency domain. There are one or more first resources, and any two adjacent first resources among the multiple first resources may be continuous or discontinuous in the frequency domain, as shown in FIG. 8a . Each first resource may occupy one or more frequency domain resource units in the frequency domain. Specifically, the network device 301 may determine one or more first resources. It can be understood that the first resource and the second resource overlap in the time domain but do not overlap in the frequency domain. When the number of the first resource and the number of the second resource are multiple, the multiple first resources One first resource and one second resource among the plurality of second resources overlap in time domain and do not overlap in frequency domain. Wherein, the quantity of the first resource and the quantity of the second resource may be the same, and the first resource of the plurality of first resources corresponds to the second resource of the plurality of second resources one-to-one, that is, the number of the plurality of first resources One first resource and one second resource among the plurality of second resources overlap in time domain and do not overlap in frequency domain. Alternatively, the quantity of the first resource and the quantity of the second resource may be different, for example, at least two first resources among the plurality of first resources correspond to one second resource among the plurality of second resources, for example, the plurality of first resources The two first resources and one second resource among the plurality of second resources overlap in the time domain, and the two first resources and the one second resource do not overlap in the frequency domain.

Wherein, each second resource may be 20 consecutive RBs in the frequency domain, and refer to the relevant description in FIG. 1 for details. The number of second resources may be multiple. Among the multiple second resources, any two adjacent second resources may occupy RBs with the same index in the frequency domain, or may occupy RBs with different indexes. In the embodiment of the present application There is no limit to this. In this embodiment of the present application, an introduction is made by taking RBs with the same index that any two adjacent second resources may occupy in the frequency domain as an example.

Exemplarily, the first resource includes frequency domain resource units indicated by the first index value, and the second resource includes frequency domain resource units indicated by the second index value. In the case that the frequency domain resource unit is realized as RB, the system bandwidth includes 90 RBs, and the index value is 0-89. Exemplarily, the value of the first index value includes one of the following: 45, 46, 47, {48, 49}, or {50, 51, 52} and so on. Wherein, {48, 49} indicates that the first resource includes an RB with an index of 48 and an RB with an index of 49. Taking the communication signal implemented as an SSB signal as an example, the value of the second index value includes one of the following: {0 to 19}, {1 to 20}, {2 to 21}, or {3 to 22} and so on. Wherein, {0 to 19} indicates that the second resource includes RBs with indexes 0 to 19. It should be understood that as long as any value in the first index value is different from all values in the second index value, the first index value and the second index value may also have other values, which are not limited in this embodiment of the present application . Below, the first index value and the second index value are introduced through two implementation methods:

As a first implementation manner, the first index value is smaller than the second index value. That is, each value in the first index value is smaller than all the values in the second index value.

Exemplarily, referring to FIG. 8a , taking the system bandwidth of 60 RBs as an example, one frequency domain resource unit may include one RB. The first resource occupies 20 RBs, the value of the first index value ranges from 0 to 19, and the first index value may be recorded as {0 to 19}. That is, the first index value indicates the 20 RBs with the smallest frequency in the system bandwidth. In the case that the communication signal is implemented as an SSB signal, the number of RBs occupied by the second resource is 20, for example, the value of the second index value includes 30 to 49, and the second index value may be recorded as {30 to 49}.

Alternatively, one frequency domain resource unit may include 20 RBs, that is, every 20 RBs is recorded as one frequency domain resource unit. In this case, taking the system bandwidth including 10 frequency domain resource units (that is, the system bandwidth including 200 RBs) as an example, the indices of the frequency domain resource units are 0-9. The first resource occupies one frequency domain resource unit (that is, the first resource occupies 20 RBs), and the frequency domain resource unit occupied by the first resource is located in one or more frequency domain resources in the first N frequency domain resource units of the system bandwidth Unit, N is a positive integer. For example, the value of the first index value is 0, and the value of N may be 3. That is to say, the first resource includes one frequency domain resource unit in the first three frequency domain resource units of the system bandwidth. Among them, the first N frequency domain resource units of the system bandwidth can be understood as that all frequency domain resource units in the system bandwidth are arranged in order of frequency from low to high. In this case, the first N frequency domain resource units of the system bandwidth , may refer to the N frequency domain resource units with the smallest frequencies in the system bandwidth. In other words, the first resource occupies X frequency domain resource units with the smallest frequency in the system bandwidth, where X is a positive integer, and X≤N. In the case that the communication signal is implemented as an SSB signal, the second resource occupies one frequency domain resource unit (that is, the second resource occupies 20 RBs), for example, the value of the second index value may include 7. It should be understood that a frequency domain resource unit may also include other numbers of RBs, such as 10 RBs, and the embodiment of the present application does not limit the number of RBs in the frequency domain resource unit.

As a second implementation manner, the first index value is greater than the second index value. That is, each value in the first index value is greater than all the values in the second index value.

Exemplarily, referring to FIG. 8 b , still taking the system bandwidth of 60 RBs as an example, one frequency domain resource unit may include one RB. The first resource occupies 20 RBs, the value of the first index value includes 40 to 59, and the first index value may be recorded as {40 to 59}. That is, the first index value indicates the 20 RBs with the highest frequency in the system bandwidth. In the case that the communication signal is implemented as an SSB signal, the number of RBs occupied by the second resource is 20, the value of the second index value includes 0 to 19, and the second index value may be recorded as {0 to 19}.

Alternatively, one frequency domain resource unit may include 20 RBs. In this case, taking the system bandwidth including 10 frequency domain resource units (that is, the system bandwidth including 200 RBs) as an example, the indices of the frequency domain resource units are 0-9. The first resource occupies one frequency domain resource unit, and the frequency domain resource unit occupied by the first resource is located in one or more of the N frequency domain resource units at the end of the system bandwidth, where N is a positive integer. For example, the value of the first index value is 9, and the value of N may be 3. That is to say, the first resource includes one frequency domain resource unit in the last three frequency domain resource units of the system bandwidth. Among them, the end N frequency domain resource units of the system bandwidth can be understood as that all frequency domain resource units in the system bandwidth are arranged in order of frequency from low to high. In this case, the end N frequency domain resource units of the system bandwidth , may refer to the N frequency domain resource units with the highest frequencies in the system bandwidth. In other words, the first resource occupies Y frequency domain resource units with the highest frequency in the system bandwidth, Y is a positive integer, and Y≤N. In the case that the communication signal is implemented as an SSB signal, the second resource occupies one frequency-domain resource unit, the value of the second index value includes 9, and the second index value may be recorded as 9.

It should be understood that, in the case where the first signal and the communication signal are transmitted by means of frequency division multiplexing, the number of frequency domain resource units occupied by the first signal may be one or multiple, and this embodiment of the present application does not make any limited. Fig. 8a and Fig. 8b are only introduced by taking 20 RBs occupied by the first resource as an example, and the number of frequency domain resource units occupied by the first resource may have other values, which is not limited in this embodiment of the present application. The first signal may be transmitted at equal intervals in the time domain, or may be transmitted at non-equal intervals, which is not limited in this embodiment of the present application. In the case where the communication signal is implemented as an SSB signal, the distribution of the SSB signal in the time domain can be referred to the introduction of the five cases (such as case A, case B, case C, case D, and case E) shown in the explanation of terms , which will not be repeated here.

Optionally, the bandwidth of the first signal is introduced as follows: as a case, the sum of the bandwidth of the first signal and the bandwidth of the communication signal is less than or equal to the system bandwidth. For example, the system bandwidth is 60 RBs. The bandwidth of the communication signal is 20 RB. In this case, the bandwidth of the first signal may be 40 RBs or 35 RBs. Of course, the bandwidth of the first signal may also have other values, such as 20 RBs, which is not limited in this embodiment of the present application. That is, the bandwidth of the first signal is determined based on the system bandwidth and the bandwidth of the communication signal. In this way, the first signal and the communication signal respectively occupy different frequency domain resource units in the system bandwidth. Therefore, even if the network device transmits the first signal and the communication signal at the same time, since the two are transmitted in a frequency division multiplexing manner, there is no difference between the signals. will interfere. Alternatively, the bandwidth of the first signal is equal to the system bandwidth. For example, the system bandwidth is 60 RBs. In this case, the bandwidth of the first signal may be 60 RBs. Certainly, the system bandwidth may also have other values, such as 100 RBs. Correspondingly, the bandwidth of the first signal is 100 RBs, and this embodiment of the present application does not limit the size of the system bandwidth.

S702. The network device 301 transmits at least one first signal on the first resource.

Wherein, for the implementation process of S702, refer to the introduction of S402, which will not be repeated here.

In the signal transmission method 700 of the embodiment of the present application, the first resource determined by the network device is a resource that overlaps with the second resource in the time domain but does not overlap with the second resource in the frequency domain, and there is a resource position between the two. Correspondence. In this way, the first signal and the communication signal are sent through different frequency domain resources, so that the first signal and the communication signal do not collide and interfere with each other, thereby improving system communication efficiency.

In some embodiments, the first signal may or may not carry communication information. Below, two situations are introduced:

As a first case, the first signal carries communication information. Referring to Figure 9a, before executing S702, the network device 301 executes S703:

S703. The network device 301 sends indication information 1 to the terminal device 305. Correspondingly, the terminal device 305 receives the indication information 1 from the network device 301 .

Wherein, the indication information 1 indicates the resource location of the first resource, such as the resource location of the first resource in the frequency domain.

Exemplarily, the indication information 1 may carry the index value of the first resource, that is, the first index value. For example, the indication information 1 may use a preset number of bits to indicate the first index value. Wherein, for the first index value, reference may be made to the related introduction of S701, which will not be repeated here.

Alternatively, the indication information 1 may also indicate an offset between the first resource and the second resource. Wherein, the unit of the offset is a frequency-domain resource unit, such as RB, and the value of the offset indicates the number of frequency-domain resource units spaced between the first resource and the second resource. The offset can be represented by a preset number of bits. For example, when the offset is small, such as less than 8 RBs, the indication information 1 may use 3 bits to indicate the offset. For another example, if the offset is large, such as greater than 8 RBs, the indication information 1 may use 4 or 5 bits to indicate the offset.

Optionally, the indication information 1 also indicates the resource location of the fourth resource, such as the resource location of the fourth resource in the frequency domain. Wherein, the fourth resource and the second resource do not overlap in time domain, and the fourth resource is also used to transmit the first signal.

Exemplarily, the indication information 1 may carry an index value of the fourth resource. In the case that the system bandwidth is 60 RBs, one frequency domain resource unit includes one RB. For example, the index value corresponding to the frequency domain resource unit occupied by the fourth resource may include 0 to 59. That is to say, when the first signal does not collide with the communication signal, the bandwidth of the first signal is equal to the system bandwidth. Exemplarily, the indication information 1 also indicates that the index value of the fourth resource includes 0 to 59. For another example, the index value corresponding to the frequency domain resource unit occupied by the fourth resource may include 0 to 35. That is to say, if the first signal does not collide with the communication signal, the first signal occupies a part of the system bandwidth. Exemplarily, the indication information 1 also indicates that the index value of the fourth resource includes 0 to 35. In the case that the system bandwidth is 100 RBs, one frequency domain resource unit includes 20 RBs. For example, the index value corresponding to the frequency domain resource unit occupied by the fourth resource may include 0-4. That is to say, when the first signal does not collide with the communication signal, the bandwidth of the first signal is equal to the system bandwidth. Exemplarily, the indication information 1 also indicates that the index value of the fourth resource includes 0-4. For another example, the index value corresponding to the frequency domain resource unit occupied by the fourth resource may include 0-3. That is to say, if the first signal does not collide with the communication signal, the first signal occupies a part of the system bandwidth. Exemplarily, the indication information 1 also indicates that the index value of the fourth resource includes 0 to 3.

In the case that the first signal carries communication information, referring to FIG. 9b, before performing S702, the network device 301 may also perform S704:

S704. The network device 301 sends the indication information 2 to the terminal device 305. Correspondingly, the terminal device 305 receives the indication information 2 from the network device 301 .

Wherein, the indication information 2 at least indicates the bandwidth. Below, two examples are introduced:

Example 1, instruction information 2 indicates the following two items:

In the first item, the sum of the first bandwidth and the bandwidth of the communication signal is less than or equal to the system bandwidth. Wherein, the first bandwidth is a bandwidth when the first signal and the communication signal overlap in time domain. Exemplarily, the system bandwidth is still 60 RBs. The bandwidth of the communication signal is 20 RB. In this case, the first bandwidth may be 40 RBs or 35 RBs. Certainly, the first bandwidth may also have other values, such as 20 RBs, which is not limited in this embodiment of the present application. That is to say, when the bandwidth of the first signal is the system bandwidth, the network device indicates to the terminal device the first bandwidth when the first signal overlaps with the communication signal. Correspondingly, the terminal device receives the first signal based on the first bandwidth indicated by the indication information 2 .

The second term, the second bandwidth is equal to the system bandwidth. Wherein, the second bandwidth is a bandwidth when the first signal and the communication signal do not overlap in time domain. Exemplarily, the system bandwidth is still 60 RBs. In this case, the second bandwidth may be 60 RBs. Certainly, the system bandwidth may also have other values, such as 100 RBs. Correspondingly, the second bandwidth is 100 RBs, and this embodiment of the present application does not limit the size of the system bandwidth. That is to say, when the bandwidth configured by the first signal is the system bandwidth, the network device indicates to the terminal device the second bandwidth when the first signal does not overlap with the communication signal. Correspondingly, the terminal device receives the first signal based on the second bandwidth indicated by the indication information 2.

Example 2, instruction information 2 indicates the following two items:

In the first term, the bandwidth of the first signal is equal to the system bandwidth. Exemplarily, the system bandwidth is still 60 RBs. In this case, the bandwidth of the first signal may be 60 RBs. Certainly, the system bandwidth may also have other values, such as 100 RBs. Correspondingly, the bandwidth of the first signal is 100 RBs, and this embodiment of the present application does not limit the size of the system bandwidth.

The second item is that the network device does not send the first signal on the second resource. In this case, if the first signal and the communication signal overlap in the time domain, the first resource includes frequency domain resource units in the system bandwidth except the second resource. Exemplarily, the system bandwidth is still 60 RBs, and the communication signal bandwidth is 20 RBs. In this case, the first resource includes 40 RBs. Certainly, the system bandwidth may also have other values, such as 100 RBs. Correspondingly, the first resource includes 80 RBs, and this embodiment of the present application does not limit the size of the system bandwidth. The second resource carrying the communication signal is used to send the communication signal instead of the first signal. That is, when the first signal and the communication signal overlap in the time domain, the network device 301 does not send the first signal on the second resource, but sends the first signal to the terminal device 305 on the first resource. Correspondingly, the terminal device 305 does not receive the first signal on the second resource, but receives the first signal from the network device 301 on the first resource. If the first signal and the communication signal do not overlap in the time domain, the first signal occupies all resources of the system bandwidth. That is to say, in the case that the first signal and the communication signal do not overlap in the time domain, the network device 301 sends the first signal to the terminal device 305 on the full bandwidth of the system bandwidth. Correspondingly, the terminal device 305 receives the first signal from the network device 301 on the full bandwidth of the system bandwidth.

Exemplarily, the indication information (such as the indication information 1 in S703 above, or the indication information 2 in S704) may be high layer signaling, such as RRC signaling, or the indication information may also be physical layer signaling, such as DCI.

It should be understood that the network device 301 executes S703, but does not execute S704, and correspondingly, the terminal device 305 executes S703, but does not execute S704. Alternatively, the network device 301 executes S704 instead of S703, and correspondingly, the terminal device 305 executes S704 instead of S703. In this way, the terminal device 305 can receive at least one first signal based on the indication information 1 or the indication information 2 . Wherein, when the terminal device 305 executes S704, since the terminal device 305 can determine the resource location of the second resource, the terminal device 305 determines the resource location of the first resource based on the system bandwidth and the resource location of the second resource, or The location range where the first resource is located. Afterwards, the terminal device 305 receives the first signal based on the resource location of the first resource, or the location range where the first resource is located.

In the case that S703 or S704 is executed, for the specific implementation process of S702, refer to the introduction of S402a, which will not be repeated here.

It should be noted that after the network device 301 sends the indication information to the terminal device 305 (such as the indication information 1 in S703 above, or the indication information 2 in S704), if the terminal device 305 receives the indication information, the terminal device 305 can Send ACK or NACK to the network device 301 , for details, refer to the introduction in the signal transmission method 400 .

As a second case, no communication information is carried on the first signal. In this case, the network device 301 does not need to execute S703 and S704 before executing S702. That is, it is enough for the network device 301 to transmit the first signal according to the resource location of the first resource.

For the network device 301, the network device 301 can also send a communication signal, that is, the network device 301 sends at least one communication signal to the terminal device 305 on the second resource. Correspondingly, the terminal device 305 may receive at least one communication signal from the network device 301 on the second resource. Implicitly, the network device 301 does not send the first signal to the terminal device 305 on the second resource. Correspondingly, the terminal device 305 does not receive the first signal from the network device 301 on the second resource.

That is to say, the network device transmits the first signal and the communication signal in a frequency division multiplexing manner.

It should be understood that, in the signal transmission method 400 and the signal transmission method 700 in the embodiments of the present application, only the subcarrier spacing for transmitting SSB signals is 120 kHz as an example for introduction. Of course, the subcarrier spacing can also be replaced by other values, and the core idea of the signal transmission method in the embodiment of the present application is also applicable. In the signal transmission method 400 and the signal transmission method 700 of the embodiments of the present application, the system bandwidth may refer to the bandwidth supported by one carrier in the NR system. For example, the carrier bandwidth of the NR system may be one of 10 MHz, 15 MHz, 20 MHz, 50 MHz, 100 MHz, and 400 MHz. Wherein, one carrier may be configured with multiple partial bandwidths (bandwidth part, BWP). Of course, the system bandwidth may also refer to the bandwidth supported by a serving cell in the LTE system, which is not limited in this embodiment of the present application.

The foregoing mainly introduces the solution provided by the embodiment of the present application from the perspective of interaction between various network elements. Correspondingly, the embodiment of the present application further provides a communication device, and the communication device may be the network element in the foregoing method embodiment, or a device including the foregoing network element, or may be a component applicable to the network element. It can be understood that, in order to realize the above functions, the communication device includes hardware structures and/or software modules corresponding to each function. Those skilled in the art should easily realize that the present application can be implemented in the form of hardware or a combination of hardware and computer software in combination with the units and algorithm steps of each example described in the embodiments disclosed herein.
