technical field

The present application relates to the field of communication technologies, and in particular, to a resource configuration method and apparatus.

Background technique

A reference signal (RS), which can also be referred to as a "pilot" signal, is a known signal provided by the transmitter to the receiver and used for channel estimation or channel sounding. Taking the reference signal as the sounding reference signal (SRS) as an example, the SRS can be used to estimate the uplink channel quality and channel selection, calculate the signal to interference plus noise ratio (SINR) of the uplink channel, and also It can be used to obtain uplink channel coefficients; in the TDD scenario, the uplink and downlink channels are mutually exclusive, and SRS can also be used to obtain downlink channel coefficients.

In the existing protocol, the base station configures the SRS resource for the terminal through radio resource control (radio resource control, RRC) signaling, so that the terminal can send the SRS on the SRS resource. Currently, one SRS resource configured by the base station for the terminal must occupy a continuous frequency band in the frequency domain. As a result, the frequency domain resources of SRS may not be suitable for some special scenarios. For example, when there is narrowband interference, a continuous frequency band occupied by SRS resources cannot flexibly avoid the interference bandwidth. It can be seen that the existing configuration of the frequency domain resources of the SRS needs to be improved.

detailed description

In the description of this application, unless otherwise stated, "/" means "or", for example, A/B can mean A or B. In this article, "and/or" is only an association relationship to describe the associated objects, which means that there can be three kinds of relationships, for example, A and/or B, which can mean that A exists alone, A and B exist at the same time, and B exists alone these three situations. Further, "at least one" means one or more, and "plurality" means two or more. In this application, the words "exemplary" or "such as" are used to mean serving as an example, illustration, or illustration. Any embodiment or design described in this application as "exemplary" or "such as" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present the related concepts in a specific manner.

Currently, the base station configures SRS resources for the terminal through radio resource control (radio resource control, RRC) signaling. The RRC signaling may be used to indicate information such as the number of ports occupied by the SRS resource, frequency domain resources, time domain resources, period, comb tooth, cyclic shift value, sequence identifier (Identity, ID).

The frequency domain resources occupied by the SRS resources may be determined by a set of frequency domain parameters in the RRC signaling. For convenience of description, the frequency domain resources occupied by the SRS resources may be referred to as configuration bandwidth or SRS frequency domain resources for short.

Specifically, this group of frequency domain parameters includes: n _RRC , n _shift , B _SRS , C _SRS and b _hop .

Wherein, the starting position of the SRS resource in the frequency domain may be determined according to n _RRC and n _shift .

The number of resource blocks (resource blocks, RBs) m _SRS,b' occupied by the SRS resources can be determined according to b _hop , C _SRS and Table 1. where b ′ in m _SRS,b′ ^is equal to b _hop . For example, assuming b _hop =0 and C _SRS =9, by looking up Table 1, m _SRS,b' =32 can be determined.

The number of resource blocks m _{SRS , b} occupied by the SRS resources in one time domain symbol can be determined according to B _SRS , C _SRS and Table 1. where b in m _SRS,b is equal to B _SRS . For example, assuming B _SRS =2 and C _SRS =9, by looking up Table 1, m _SRS,b =8 can be determined.

Table 1

When b _hop ≥B _SRS , the terminal does not enable frequency hopping. That is, the terminal transmits the SRS in a non-frequency hopping manner. It should be understood that in the case of adopting the non-frequency hopping manner, the SRS sent by the terminal at one time covers the configured bandwidth of the entire SRS resource.

When b _hop < B _SRS , the terminal enables frequency hopping. That is, the terminal transmits the SRS in a frequency hopping manner. It should be understood that in the case of frequency hopping, the SRS sent by the terminal each time only covers a part of the configured bandwidth of the SRS resources, and the terminal sends the SRS multiple times in one frequency hopping period to cover the entire configured bandwidth of the SRS resources.

Take FIG. 1 as an example for illustration. In Figure 1, a block represents 4 RBs in the frequency domain, so the configuration bandwidth of the SRS resource includes 48 RBs, and the number of RBs occupied by the SRS in one time domain symbol is 12, so the terminal can perform frequency hopping in the 4 time domains. The SRS is sent on the symbol, and the bandwidth of each time-domain symbol is a quarter of the overall configured bandwidth. In Fig. 1, the small black squares represent the 4 RBs that carry the SRS.

In this embodiment of the present application, the number of frequency hopping in one frequency hopping period is equal to the number of times the terminal needs to send SRS in one frequency hopping period. Exemplarily, the number of frequency hopping in FIG. 1 is 4.

Optionally, the number of hops is equal to

Wherein, N _b is determined according to _CSRS and Table 1.

For example, assuming b _hop =0, _{CSRS =9, and B SRS} ₌ 2, the number of frequency hopping is equal to 2×2=4.

Currently, the SRS resources configured for the terminal by the network device occupy a continuous frequency band in the frequency domain. In this way, as shown in FIG. 2 , when there is narrowband interference, the frequency band occupied by the SRS resources cannot flexibly avoid the interference bandwidth. When the interference bandwidth overlaps with the frequency band occupied by the SRS resources, if the terminal transmits the SRS on the interference bandwidth, the transmission power will be wasted, and the channel estimation performance of the SRS by the network equipment is poor due to the influence of the interference. In addition, when the interference bandwidth overlaps with the frequency band occupied by the SRS resources, if the base station only estimates the channel of the non-interference bandwidth during channel estimation, the orthogonality between the code division users may be destroyed, and the channel estimation performance may be degraded.

Therefore, how to configure the frequency domain resources of the SRS more flexibly so that the frequency domain resources of the SRS can be applied to more scenarios (eg, a scenario with interference bandwidth) is an urgent technical problem to be solved.

In order to solve the above technical problems, embodiments of the present application provide a resource configuration method and apparatus. The technical solutions provided in the embodiments of the present application can be applied to various communication systems, for example, a Long Term Evolution (LTE) communication system, a new radio (NR) using the fifth generation (5th generation, 5G) communication technology ) communication system, future evolution system or multiple communication fusion systems, etc. The technical solutions provided in this application can be applied to various application scenarios, such as machine to machine (M2M), macro-micro communication, enhanced mobile broadband (eMBB), ultra-reliable and ultra-low latency Communication (ultra-reliable & low latency communication, uRLLC) and massive IoT communication (massive machine type communication, mMTC) and other scenarios. These scenarios may include but are not limited to: a communication scenario between a communication device and a communication device, a communication scenario between a network device and a network device, a communication scenario between a network device and a communication device, and the like.

As shown in FIG. 3 , an architecture diagram of a communication system provided by an embodiment of the present application, the communication system architecture may include one or more network devices (only one is shown in FIG. 3 ) and one or more network devices connected to each network device. multiple terminals.

The network device may be a base station or a base station controller for wireless communication. For example, the base station may include various types of base stations, such as a micro base station (also referred to as a small cell), a macro base station, a relay station, an access point, etc., which are not specifically limited in this embodiment of the present application. In the embodiment of the present application, the base station may be an evolutional node B (evolutional node B, eNB or e-NodeB) in long term evolution (long term evolution, LTE), an internet of things (internet of things, IoT) or a narrowband thing The eNB in the Internet of Things (narrow band-internet of things, NB-IoT), the base station in the future 5G mobile communication network or the future evolution of the public land mobile network (public land mobile network, PLMN), the embodiment of this application does not make any limit. In this embodiment of the present application, the apparatus for implementing the function of the network device may be the network device, or may be an apparatus capable of supporting the network device to implement the function, such as a chip system. In the embodiments of the present application, the technical solutions provided by the embodiments of the present application are described by taking the device for realizing the function of the network device being a network device as an example.

The network equipment mentioned in this application, such as a base station, generally includes a baseband unit (baseband unit, BBU), a remote radio unit (remote radio unit, RRU), an antenna, and a feeder for connecting the RRU and the antenna. Among them, the BBU is used for signal modulation. The RRU is responsible for radio frequency processing. The antenna is responsible for the conversion between the guided traveling waves on the cable and the space waves in the air. On the one hand, the distributed base station greatly shortens the length of the feeder between the RRU and the antenna, which can reduce the signal loss and the cost of the feeder. On the other hand, the RRU plus antenna is relatively small and can be installed anywhere, making network planning more flexible. In addition to the remote RRU, all BBUs can also be centralized and placed in the central office (CO). Through this centralized method, the number of base station computer rooms can be greatly reduced, and supporting equipment, especially air conditioners, can be reduced. Energy consumption can reduce a lot of carbon emissions. In addition, after the scattered BBUs are integrated into a BBU baseband pool, they can be managed and scheduled in a unified manner, and resource allocation is more flexible. In this mode, all physical base stations have evolved into virtual base stations. All virtual base stations share the user's data transmission and reception, channel quality and other information in the BBU baseband pool, and cooperate with each other to realize joint scheduling.

In some deployments, a base station may include a centralized unit (CU) and a distributed unit (DU). The base station may also include an active antenna unit (AAU). The CU implements some functions of the base station, and the DU implements some functions of the base station. For example, the CU is responsible for processing non-real-time protocols and services, and implementing functions of radio resource control (RRC) and packet data convergence protocol (PDCP) layers. The DU is responsible for processing physical layer protocols and real-time services, and implementing functions of the radio link control (RLC), media access control (MAC), and physical (PHY) layers. AAU implements some physical layer processing functions, radio frequency processing and related functions of active antennas. Since the information of the RRC layer will eventually become the information of the PHY layer, or be transformed from the information of the PHY layer, therefore, under this architecture, higher-layer signaling, such as RRC layer signaling or PDCP layer signaling, can also It is considered to be sent by DU, or, sent by DU+AAU. It can be understood that the network device may be a device including one or more of a CU node, a DU node, and an AAU node. In addition, the CU can be divided into network devices in the RAN, and the CU can also be divided into network devices in the core network (core network, CN), which is not limited here.

A terminal is a device with wireless transceiver function. Terminals can be deployed on land, including indoor or outdoor, handheld or vehicle; can also be deployed on water (such as ships, etc.); can also be deployed in the air (such as aircraft, balloons and satellites, etc.). The terminal equipment may be user equipment (user equipment, UE). Wherein, the UE includes a handheld device, a vehicle-mounted device, a wearable device or a computing device with a wireless communication function. Exemplarily, the UE may be a mobile phone, a tablet computer, or a computer with a wireless transceiver function. The terminal device may also be a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in telemedicine, intelligent Wireless terminals in power grids, wireless terminals in smart cities, wireless terminals in smart homes, and so on. In this embodiment of the present application, the device for implementing the function of the terminal may be a terminal, or may be a device capable of supporting the terminal to implement the function, such as a chip system. In this embodiment of the present application, the chip system may be composed of chips, or may include chips and other discrete devices. In the embodiments of the present application, the technical solutions provided by the embodiments of the present application are described by taking the device for realizing the functions of the terminal as the terminal as an example.

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

As shown in FIG. 5, a resource configuration method provided by an embodiment of the present application includes the following steps:

S101. The network device generates SRS resource configuration information.

The SRS resource configuration information may be used to configure one SRS resource.

In this embodiment of the present application, the SRS resource configuration information includes N groups of frequency domain parameters, where N is a positive integer greater than 1.

It should be understood that in different communication systems, a set of frequency domain parameters in the SRS resource configuration information may include different parameters. This embodiment of the present application does not limit the specific parameters included in a set of frequency domain parameters.

Exemplarily, taking the embodiment of the present application applied to an NR system as an example, a set of frequency domain parameters may include: frequency domain location parameters, frequency domain offset parameters, symbol bandwidth parameters, bandwidth set parameters, and configuration bandwidth parameters. Wherein, the frequency domain position parameter can be n _RRC mentioned above, the frequency domain offset parameter can be n _shift mentioned above, the symbol bandwidth parameter can be _BSRS mentioned above, and the bandwidth set parameter can be the above For the _CSRS mentioned in the text, the configuration bandwidth parameter may be the b _hop mentioned above. The functions of n _RRC , n _shift , B _SRS , C _SRS and b _hop may refer to the introduction in the prior art, and will not be repeated here.

In an optional embodiment, the configuration information may include one or more of the following: freqDomainPosition - configuration n _RRC , freqDomainShift parameter - configuration n _shift , freqHopping parameter - configuration B _SRS , C _SRS or one or more of b _hop parameters indivual.

It should be understood that the names of the above-mentioned frequency domain position parameters, frequency domain offset parameters, symbol bandwidth parameters, bandwidth set parameters, and configuration bandwidth parameters are only examples. In different communication systems, the above frequency domain parameters may have different names.

In this embodiment of the present application, a set of frequency domain parameters is used to determine a frequency domain sub-resource of the SRS resource in the frequency domain. A frequency domain sub-resource is a part of the frequency domain resources occupied by the SRS resource. The frequency domain sub-resources may have other names, such as sub-bands, etc., which are not limited in this embodiment of the present application.

One frequency domain sub-resource occupies one or more frequency domain units in the frequency domain. The number of frequency-domain units occupied by a frequency-domain sub-resource in the frequency domain may be determined by a set of frequency-domain parameters corresponding to the frequency-domain sub-resource. Further, in the NR system, the number of frequency-domain units occupied by a frequency-domain sub-resource in the frequency domain is determined according to the _CSRS and b _hop in a set of frequency-domain parameters corresponding to the frequency-domain sub-resource.

Optionally, the above frequency domain unit refers to a resource block (resource block, RB). One resource block may consist of multiple subcarriers. For example, when the subcarrier spacing is 15 kHz, one RB may include 12 subcarriers.

The N groups of frequency domain parameters are in one-to-one correspondence with the N frequency domain sub-resources. It should be understood that the frequency domain resources occupied by the SRS resources may be composed of the N frequency domain sub-resources. Therefore, the bandwidth of the frequency domain resource occupied by the SRS resource is the sum of the bandwidths of the N frequency domain sub-resources.

In this embodiment of the present application, the N frequency domain sub-resources do not overlap and are not continuous in the frequency domain.

It should be understood that the N frequency domain sub-resources are non-overlapping and discontinuous in the frequency domain, specifically, any two frequency-domain sub-resources in the N frequency domain sub-resources are non-overlapping and discontinuous in the frequency domain.

For any two frequency-domain sub-resources in the N frequency-domain sub-resources, the two frequency-domain sub-resources do not overlap in the frequency domain, which means that the two frequency-domain sub-resources do not occupy the same frequency-domain unit in the frequency domain .

For example, it is assumed that frequency-domain sub-resource #1 occupies RB#1-RB#5, and frequency-domain subresource #2 occupies RB#4-RB#10. Since both the frequency-domain sub-resource #1 and the frequency-domain sub-resource #2 occupy RB#4 and RB#5, it can be determined that the frequency-domain sub-resource #1 and the frequency-domain sub-resource #2 partially overlap in the frequency domain.

For another example, it is assumed that frequency domain sub-resource #1 occupies RB#1-RB#5, and frequency-domain subresource #2 occupies RB#6-RB#10. Since the frequency domain subresource #1 and the frequency domain subresource #2 do not occupy the same RB, the frequency domain subresource #1 and the frequency domain subresource #2 do not overlap in the frequency domain.

For any two frequency-domain sub-resources in the N frequency-domain sub-resources, the two frequency-domain sub-resources are discontinuous in the frequency domain, which refers to the last frequency-domain unit occupied by one frequency-domain sub-resource in the frequency domain It is not adjacent to the first frequency domain unit occupied by another frequency domain sub-resource in the frequency domain.

For example, it is assumed that frequency-domain sub-resource #1 occupies RB#1-RB#5, and frequency-domain subresource #2 occupies RB#6-RB#10. The last RB occupied by the frequency domain subresource #1 is RB#5, and the first RB occupied by the frequency domain subresource #2 is RB#6. Since RB#5 and RB#6 are adjacent, the frequency domain subresource #1 and the frequency domain subresource #2 are contiguous in the frequency domain.

For another example, it is assumed that frequency domain sub-resource #1 occupies RB#1-RB#5, and frequency-domain subresource #2 occupies RB#7-RB#10. The last RB occupied by the frequency domain subresource #1 is RB#5, and the first RB occupied by the frequency domain subresource #2 is RB#7. Since RB#5 and RB#7 are not adjacent, frequency domain subresource #1 and frequency domain subresource #2 are not contiguous.

Optionally, the frequency domain units occupied by the frequency domain sub-resources may be sorted in order from low frequency to high frequency. In this case, the first frequency-domain unit in the frequency-domain subresource is the frequency-domain unit with the lowest frequency in the frequency-domain subresource, and the last frequency-domain unit in the frequency-domain subresource is the frequency in the frequency-domain subresource. The highest frequency domain unit.

Optionally, the frequency domain units occupied by the frequency domain sub-resources may be sorted in order from high frequency to low frequency. In this case, the first frequency-domain unit in the frequency-domain subresource is the frequency-domain unit with the highest frequency in the frequency-domain subresource, and the last frequency-domain unit in the frequency-domain subresource is the frequency in the frequency-domain subresource. lowest frequency domain unit.

Optionally, in order to avoid the interference of the interference bandwidth, the above-mentioned N frequency domain sub-resources do not overlap with the interference bandwidth. That is, for any frequency-domain sub-resource in the N frequency-domain sub-resources, the frequency-domain sub-resource and the interference bandwidth do not occupy the same frequency-domain unit in the frequency domain.

It should be understood that the network device may first determine the positions of the N frequency-domain sub-resources in the frequency domain; then, for any frequency-domain sub-resource in the N frequency-domain sub-resources, the network device may determine the location of the frequency-domain sub-resources in the frequency domain according to the position, and determine a set of frequency domain parameters corresponding to the frequency domain sub-resources.

Optionally, the SRS resource configuration information may include other configuration parameters in addition to the N groups of frequency domain parameters. For example, the SRS resource configuration information may further include time domain parameters, code domain parameters, and the like.

S102. The network device sends SRS resource configuration information to the terminal. Correspondingly, the terminal receives the SRS resource configuration information sent by the network device.

Optionally, the SRS resource configuration information may be carried in RRC signaling.

S103. The terminal determines the SRS resource according to the SRS resource configuration information.

As a possible implementation manner, the terminal determines N frequency domain sub-resources of the SRS resource in the frequency domain according to N groups of frequency domain parameters in the SRS resource configuration information.

Based on the technical solution shown in FIG. 5 , compared with the prior art that the SRS resources configured by the SRS resource configuration information can only occupy a continuous frequency band in the frequency domain, the SRS resource configuration information provided by the embodiment of the present application includes N groups of frequency domain parameters, so that the SRS resources occupy N frequency domain sub-resources in the frequency domain, and the N frequency domain sub-resources are non-overlapping and discontinuous, so that the SRS resources can be more flexible in the frequency domain to adapt to different application scenarios (such as Scenarios where there is interference bandwidth).

Optionally, based on the embodiment shown in FIG. 5, as shown in FIG. 6, the resource configuration method further includes steps S104-S105.

S104, the terminal sends the SRS to the network device on the SRS resource.

It should be noted that the SRS time-domain transmission modes include: periodic transmission, semi-persistent transmission, and aperiodic transmission.

When the time domain transmission mode configured by the SRS resource configuration information is periodic transmission, after receiving the SRS resource configuration information, the terminal periodically transmits the SRS on the SRS resource.

When the time-domain transmission mode configured in the SRS resource configuration information is semi-persistent transmission, the terminal periodically transmits the SRS on the SRS resource after receiving the MAC layer signaling for activating the semi-persistent transmission.

When the time domain transmission mode configured in the SRS resource configuration information is aperiodic transmission, the terminal transmits the SRS on the SRS resource after receiving the DCI signaling for activating the aperiodic transmission.

In this embodiment of the present application, the terminal may send the SRS on the SRS resource in a frequency hopping manner. Alternatively, the terminal may send the SRS on the SRS resource in a non-frequency hopping manner.

Optionally, whether the terminal uses frequency hopping to send the SRS depends on whether there is at least one set of frequency domain parameters in the N sets of frequency domain parameters that meets the preset condition. That is, when at least one set of frequency domain parameters in the N sets of frequency domain parameters meets the preset condition, the terminal transmits the SRS in a frequency hopping manner. Alternatively, when none of the N groups of frequency domain parameters meet the preset conditions, the terminal transmits the SRS in a non-frequency hopping manner.

Optionally, for a set of frequency domain parameters, the preset condition is: b _hop is less than B _SRS .

Optionally, when the terminal transmits the SRS in a frequency hopping manner on the SRS resource, the frequency hopping times of the SRS in one frequency hopping period is equal to the sum of the frequency hopping times determined by each group of frequency domain parameters in the N groups of frequency domain parameters.

Exemplarily, the number of frequency hopping of the SRS in one frequency hopping period is equal to

It should be understood that

Frequency hopping times determined for the nth group of frequency domain parameters.

Among them, n is a positive integer greater than or equal to 1 and less than or equal to N. B _SRS,n is the symbol bandwidth parameter in the nth group of frequency domain parameters in the SRS resource configuration information, and b _hop,n is the configured bandwidth parameter in the nth group of frequency domain parameters in the SRS resource configuration information. N _{b,n is} determined according to _CSRS,n and b by looking up Table 1. C _SRS,n is the bandwidth set parameter in the nth group of frequency domain parameters in the SRS resource configuration information.

For example, the SRS resource configuration information includes 2 sets of frequency domain parameters. Wherein, in the first group of frequency domain parameters, C _SRS =9, B _SRS =2, and b _hop =1. Therefore, based on Table 1, the number of frequency hopping determined by the first set of frequency domain parameters is equal to two. In the second group of frequency domain parameters, C _SRS =9, B _SRS =2, and b _hop =0. Therefore, based on Table 1, the number of frequency hopping determined by the second set of frequency domain parameters is equal to four. Therefore, the number of frequency hopping of the SRS in one frequency hopping period is equal to 6.

Optionally, the terminal transmits the SRS in a frequency hopping manner on the SRS resource, and the following manner 1 or manner 2 may be used. Among them, the first mode may also be referred to as an individual frequency hopping mode, and the second mode may also be referred to as an overall frequency hopping mode.

Manner 1: The terminal determines the arrangement order of the N frequency domain sub-resources. Afterwards, the terminal transmits the SRS in a frequency hopping manner on the N frequency domain sub-resources in sequence according to the arrangement order of the N frequency-domain sub-resources.

Exemplarily, according to the arrangement order of the N frequency-domain sub-resources, the terminal transmits the SRS on the N frequency-domain sub-resources in a frequency-hopping manner in sequence, which may include the following steps S10-S13.

S10, set i=0.

S11. The terminal sends the SRS on the ith frequency domain sub-resource in a frequency hopping manner.

Based on step S11, the SRS may cover the entire i-th frequency domain sub-resource.

S12, set i=i+1.

S13. When i≤N, execute step S11; when i>N, execute step S10.

Exemplarily, referring to FIG. 7 , the SRS resource configuration information includes two sets of frequency domain parameters, the first set of frequency domain parameters corresponds to frequency domain sub-resource #1, and the second set of frequency domain sub-resources corresponds to frequency domain sub-resource #2. In one frequency hopping period, the terminal first transmits the SRS in the frequency hopping manner on the frequency domain sub-resource #1. After that, the terminal transmits the SRS on the frequency domain sub-resource #2 in a frequency hopping manner.

Optionally, the terminal determines the arrangement order of the N frequency domain sub-resources, and can adopt any one of the following methods:

(1) When the SRS resource configuration information further includes the index of each group of frequency domain parameters in the N groups of frequency domain parameters, the terminal determines N frequency domain parameters according to the index of each group of frequency domain parameters in the N groups of frequency domain parameters The order in which the subresources are sorted.

In a possible design, the terminal arranges the N groups of frequency domain parameters in ascending order of indexes, and determines the arrangement order of the N groups of frequency domain parameters. Since the N groups of frequency domain parameters are in one-to-one correspondence with the N frequency domain sub-resources, the terminal can determine the arrangement order of the N frequency domain sub-resources according to the arrangement order of the N groups of frequency domain parameters.

Based on this design, the sequence numbers of the frequency domain sub-resources corresponding to a set of frequency domain parameters with a smaller index are smaller in the arrangement order.

For example, the SRS resource configuration information includes three sets of frequency domain parameters, the first set of frequency domain parameters corresponds to frequency domain sub-resource #1, the second set of frequency domain parameters corresponds to frequency domain sub-resource #2, and the third set of frequency domain parameters corresponds to Frequency domain sub-resource #3. The index corresponding to the first set of frequency domain parameters is 2, the index corresponding to the second set of frequency domain parameters is 3, and the index corresponding to the third set of frequency domain parameters is 1. Therefore, the three sets of frequency domain parameters are arranged in order from small to large. , specifically: the third group of frequency domain parameters, the first group of frequency domain parameters, and the second group of frequency domain parameters. Based on this, the arrangement order of the three frequency-domain sub-resources is: frequency-domain sub-resource #3, frequency-domain sub-resource #1, and frequency-domain sub-resource #2. That is, the sequence number of frequency domain subresource #3 is 1 in the arrangement order, the sequence number of frequency domain subresource #1 is 2 in the arrangement order, and the sequence number of frequency domain subresource #2 is 3 in the arrangement order.

In another possible design, the terminal arranges the N groups of frequency domain parameters in descending order of indexes, and determines the arrangement order of the N groups of frequency domain parameters. Since the N groups of frequency domain parameters are in one-to-one correspondence with the N frequency domain sub-resources, the terminal can determine the arrangement order of the N frequency domain sub-resources according to the arrangement order of the N groups of frequency domain parameters.

Based on this design, the sequence number of the frequency domain sub-resources corresponding to a group of frequency domain parameters with a larger index is smaller in the arrangement order.

(2) The terminal determines the arrangement order of the N frequency-domain sub-resources according to the frequencies of the N frequency-domain sub-resources.

In a possible design, the terminal arranges the N frequency domain sub-resources in order of frequency from high to low, and determines the arrangement order of the N frequency-domain sub-resources.

Based on this design, the frequency sub-resources with higher frequencies have lower serial numbers in the arrangement order.

For example, the SRS resource configuration information includes three sets of frequency domain parameters, the first set of frequency domain parameters corresponds to frequency domain sub-resource #1, the second set of frequency domain parameters corresponds to frequency domain sub-resource #2, and the third set of frequency domain parameters corresponds to Frequency domain sub-resource #3. The three frequency sub-resources are arranged in order of frequency from high to low: frequency-domain sub-resource #3, frequency-domain sub-resource #1, and frequency-domain sub-resource #2. That is, the sequence number of the frequency domain subresource #3 in the arrangement order is 1, the sequence number of the frequency domain subresource #1 in the arrangement order is 2, and the sequence number of the frequency domain subresource #2 in the arrangement order is 3.

In another possible design, the terminal arranges the N frequency domain sub-resources in order of frequency from low to high, and determines the arrangement order of the N frequency domain sub-resources.

Based on this design, the frequency sub-resources with higher frequencies have higher serial numbers in the arrangement order.

Manner 2: The terminal determines the frequency hopping pattern according to N groups of frequency domain parameters. After that, the terminal transmits the SRS on the SRS resource in a frequency hopping manner according to the frequency hopping pattern.

Optionally, the frequency hopping pattern may be determined according to the following manner: for the i-th frequency-domain sub-resource in the N frequency-domain sub-resources, the terminal determines the hopping frequency corresponding to the i-th frequency-domain sub-resource according to the i-th group of frequency domain parameters. frequency number P _i ; after that, the terminal divides the ith frequency domain sub-resource into P _i subbands according to the frequency hopping number P _i corresponding to the ith frequency domain sub-resource. In this way, N frequency domain sub-resources can be divided into P sub-bands,

After that, the terminal generates a frequency hopping pattern according to the P subbands.

In a possible design, when the frequency hopping times corresponding to the N frequency domain sub-resources are all the same, the terminal may arrange the P sub-bands in a tree structure to generate a frequency hopping pattern.

Exemplarily, referring to FIG. 8(a), the SRS resource configuration information includes two sets of frequency domain parameters, the first set of frequency domain parameters corresponds to frequency domain sub-resource #1, and the second set of frequency domain sub-resources corresponds to frequency domain sub-resource #2. . The number of frequency hopping determined by the first group of frequency domain parameters is 2, and the number of frequency hopping determined by the second group of frequency domain parameters is 2. The frequency domain subresource #1 may be divided into subband #1 and subband #2, and the frequency domain subresource #2 may be divided into subband #3 and subband #4. Subbands #1 to #4 are arranged in a tree structure. Therefore, at the first transmission occasion, the terminal transmits the SRS on subband #1. At the second transmission occasion, the terminal transmits the SRS on subband #3. At the third transmission occasion, the terminal transmits SRS on subband #2. At the fourth transmission occasion, the terminal transmits the SRS on subband #4.

In one frequency hopping period, one sending opportunity is the time domain resource used by the terminal to send the SRS once by frequency hopping. Exemplarily, the time domain unit may be an orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbol or a time slot.

It should be understood that the number of transmission opportunities in one frequency hopping period is equal to the number of frequency hopping in one frequency hopping period. In one frequency hopping period, SRSs sent at different transmission occasions occupy different subbands.

In another possible design, when the frequency hopping times corresponding to the N frequency domain sub-resources are different, the terminal may arrange the P sub-bands according to a preset rule to generate a frequency hopping pattern. The preset rule is used to make the P subbands discretely distributed.

Optionally, the above preset rules may be pre-configured in terminals and network devices. The above-mentioned preset rules may be specified by a communication protocol. Alternatively, the above-mentioned preset rule may be determined by mutual negotiation between the terminal and the network device.

Exemplarily, referring to FIG. 8(b), the SRS resource configuration information includes two sets of frequency domain parameters, the first set of frequency domain parameters corresponds to frequency domain sub-resource #1, and the second set of frequency domain sub-resources corresponds to frequency domain sub-resource #2. . The number of frequency hopping determined by the first group of frequency domain parameters is 2, and the number of frequency hopping determined by the second group of frequency domain parameters is 4. The frequency domain sub-resource #1 can be divided into sub-band # 1-1 and sub-band # 1-2, and the frequency-domain sub-resource # 2 can be divided into sub-band # 2-1, sub-band 2-2, sub-band # 2-1 2-3, and subband #2-4. The above-mentioned subbands are arranged according to preset rules to generate a frequency hopping pattern. Therefore, at the first sending occasion, the terminal sends SRS on subband #1-1; at the second sending occasion, the terminal sends SRS on subband #2-1; at the third sending occasion, the terminal sends SRS on subband #2-1 #1-2 sends SRS; at the fourth sending occasion, the terminal sends SRS at subband #2-2; at the fifth sending occasion, the terminal sends SRS at subband #2-3; at the sixth sending occasion, The terminal transmits SRS in subbands #2-4.

Based on the second mode, there are L groups of transmission opportunities within a frequency hopping period that meet a preset condition, and any group of transmission opportunities in the L groups of transmission opportunities includes two adjacent transmission opportunities, and the preset condition is: adjacent The subbands occupied by the SRS sent on the two sending occasions belong to different frequency domain subresources in the N frequency domain subresources, and L is a positive integer greater than or equal to N.

Taking Figure 8(a) as an example, in a frequency hopping period, the SRS sent at the first transmission opportunity occupies subband #1, and the SRS sent at the second transmission opportunity occupies subband #2. Band #2 respectively belongs to different frequency domain sub-resources, therefore, the first sending occasion and the second sending occasion constitute a group of sending occasions that satisfy the preset condition.

In FIG. 8( a ), there are 3 groups of sending timings within one frequency hopping period that meet the preset conditions. The three sets of transmission timings are respectively {first transmission timing, second transmission timing}, {second transmission timing, third transmission timing}, and {third transmission timing, fourth transmission timing}.

It should be understood that using the frequency hopping method of the second method can ensure that the network device can quickly obtain channel information in a wide range in the frequency domain, which is beneficial for the network device to quickly obtain the channel information of the full bandwidth. Taking Figure 8(a) as an example, the network device obtains the channel information of subband #1 and subband #3 after two frequency hopping, and the distribution of subband #1 and subband #3 is relatively scattered over the entire bandwidth, which is beneficial to the network device. The channel information of the full bandwidth is estimated by means of interpolation or extrapolation.

S105, the network device receives the SRS sent by the terminal on the SRS resource.

It should be understood that when the terminal sends the SRS on the SRS resource in a frequency hopping manner, the network device receives the SRS on the SRS resource in a frequency hopping manner. Alternatively, when the terminal sends the SRS on the SRS resource in a non-frequency hopping manner, the network device receives the SRS on the SRS resource in a non-frequency hopping manner.

Optionally, for the network device to receive the SRS on the SRS resource in a non-frequency hopping manner, the following manner 1 or manner 2 may be adopted.

Manner 1: The network device determines the arrangement order of the N frequency domain sub-resources. After that, the network device sends the SRS in a frequency-hopping manner on the N frequency-domain sub-resources in sequence according to the arrangement order of the N frequency-domain sub-resources.

Manner 2: The network device determines the frequency hopping pattern according to N groups of frequency domain parameters. After that, the network device sends the SRS in a frequency hopping manner on the SRS resource according to the frequency hopping pattern.

For the specific details of the above-mentioned manners 1 and 2, reference may be made to the relevant description in step S104, and details are not described herein again.

Based on the technical solution shown in FIG. 6 , in the case that one SRS resource occupies N frequency domain sub-resources in the frequency domain, the terminal can send the SRS on the N frequency domain sub-resources, so that the network device can respond to the N frequency domain sub-resources. domain sub-resources for channel estimation.

As shown in FIG. 9, a resource configuration method provided by an embodiment of the present application includes the following steps:

S201. The network device generates M pieces of SRS resource configuration information.

In this embodiment of the present application, the SRS resource configuration information is used to configure one SRS resource. Therefore, the M pieces of SRS resource configuration information are in one-to-one correspondence with the M pieces of SRS resources. M is a positive integer greater than 1.

For any SRS resource configuration information in the M pieces of SRS resource configuration information, one SRS resource configuration information includes a set of frequency domain parameters, and a set of frequency domain parameters is used to determine the frequency domain resources occupied by the SRS resources in the frequency domain.

In an optional embodiment, a set of frequency domain parameters may include one or more of the following: freqDomainPosition—configure n _RRC , freqDomainShift parameter—configure n _shift , freqHopping parameter—configure B _SRS , C _SRS or b _hop parameter one or more.

In the embodiment of the present application, the above-mentioned M SRS resources do not overlap and are not consecutive in the frequency domain.

It should be understood that the M SRS resources are non-overlapping and discontinuous in the frequency domain, which specifically means that any two SRS resources in the M SRS resources are non-overlapping and discontinuous in the frequency domain.

For any two SRS resources in the M SRS resources, the two SRS resources do not overlap in the frequency domain, specifically, the two SRS resources do not occupy the same frequency domain unit in the frequency domain.

For example, it is assumed that SRS resource #1 occupies RB#1-RB#5, and SRS resource #2 occupies RB#4-RB#10. Since SRS resource #1 and SRS resource #2 both occupy RB#4 and RB#5, it can be determined that SRS resource #1 and SRS resource #2 partially overlap in the frequency domain.

For another example, it is assumed that SRS resource #1 occupies RB#1-RB#5, and SRS resource #2 occupies RB#6-RB#10. Since SRS resource #1 and SRS resource #2 do not occupy the same RB, SRS resource #1 and SRS resource #2 do not overlap in the frequency domain.

For any two SRS resources in the M SRS resources, the two SRS resources are discontinuous in the frequency domain, which specifically means that the last frequency domain unit occupied by one SRS resource in the frequency domain is in the same range as the other SRS resource. The first frequency domain unit occupied on the frequency domain is not adjacent.

For example, it is assumed that SRS resource #1 occupies RB#1-RB#5, and SRS resource #2 occupies RB#6-RB#10. The last RB occupied by SRS resource #1 is RB#5, and the first RB occupied by SRS resource #2 is RB#6. Since RB#5 and RB#6 are adjacent, SRS resource #1 and SRS resource #2 are contiguous in the frequency domain.

For another example, it is assumed that SRS resource #1 occupies RB#1-RB#5, and SRS resource #2 occupies RB#7-RB#10. The last RB occupied by SRS resource #1 is RB#5, and the first RB occupied by SRS resource #2 is RB#7. Since RB#5 and RB#7 are not adjacent, SRS resource #1 and SRS resource #2 are not contiguous.

Optionally, the frequency domain units occupied by the SRS resources may be sorted in order from low frequency to high frequency. In this case, the first frequency domain unit in the SRS resource is the frequency domain unit with the lowest frequency in the SRS resource, and the last frequency domain unit in the SRS resource is the frequency domain unit with the highest frequency in the SRS resource.

Optionally, the frequency domain units occupied by the SRS resources may be sorted in order from high frequency to low frequency. In this case, the first frequency domain unit in the SRS resource is the frequency domain unit with the highest frequency in the SRS resource, and the last frequency domain unit in the SRS resource is the frequency domain unit in the SRS resource with the lowest frequency.

Optionally, in order to avoid the influence of the interference bandwidth, the above-mentioned M SRS resources do not overlap the interference bandwidth in the frequency domain. That is, any SRS resource in the M SRS resources does not occupy the same frequency domain unit as the interference bandwidth in the frequency domain.

In this embodiment of the present application, the M SRS resources are associated with the same antenna port. It should be understood that the above-mentioned antenna ports are SRS ports. Since the M SRS resources are associated with the same antenna port, the channel parameters of the M SRS resources can be shared, so that the SRS transmitted on the M SRS resources can jointly perform channel estimation. The above-mentioned channel references can be large-scale coefficients, delay spreads, beam directions, etc.

In a possible design, the network device uses an implicit manner to indicate to the terminal that the M SRS resources are associated with the same antenna port.

In another possible design, the network device uses an explicit manner to indicate to the terminal that the M SRS resources are associated with the same antenna port. For example, the network device sends indication information to the terminal, where the indication information is used to indicate that the M SRS resources are associated with the same antenna port. It should be understood that the above indication information may be sent together with the M pieces of SRS resource configuration information. Alternatively, the above-mentioned indication information can also be sent independently.

Optionally, the above-mentioned M pieces of SRS resource configuration information include the same time domain parameters. The time domain parameter may be a period and/or a time domain offset value.

Optionally, the comb teeth, cyclic shift values and/or sequence IDs used by the M SRS resources may be the same or different, which is not limited in this embodiment of the present application.

S202: The network device sends M pieces of SRS resource configuration information to the terminal. Correspondingly, the terminal receives M pieces of SRS resource configuration information sent by the network device.

Optionally, the M pieces of SRS resource configuration information may be carried in RRC signaling.

It should be understood that the M pieces of SRS resource configuration information may be sent simultaneously or separately.

It should be understood that the M pieces of SRS resource configuration information may be encapsulated in the same signaling, or may be encapsulated in different signaling.

S203. The terminal determines M SRS resources according to the M SRS resource configuration information.

Based on the embodiment shown in FIG. 9 , the network device sends M pieces of SRS resource configuration information to the terminal to configure the M pieces of SRS resources. Since the M SRS resources are associated with the same antenna port, the SRS transmitted on the M SRS resources can jointly perform channel estimation. However, the M SRS resources do not overlap and are discontinuous in the frequency domain, thereby realizing more flexible configuration of the SRS frequency domain resources to adapt to different application scenarios (eg, scenarios with interference bandwidth).

Optionally, based on the embodiment shown in FIG. 9, as shown in FIG. 10, the resource configuration method further includes steps S204-S205.

S204, the terminal sends the SRS on the M SRS resources.

When the time domain sending mode of the M SRS resources is periodic sending, after receiving the M SRS resource configuration information, the terminal periodically sends the SRS on the M SRS resources.

When the time domain transmission mode of the M SRS resources is semi-persistent transmission, after receiving the MAC layer signaling for activating the semi-persistent transmission, the terminal periodically transmits the SRS on the M SRS resources.

When the time domain transmission mode of the M SRS resources is aperiodic transmission, after receiving the DCI signaling for activating the aperiodic transmission, the terminal sends the SRS on the M SRS resources.

In the embodiment of the present application, the terminal may send the SRS in the frequency hopping manner on the M SRS resources. Alternatively, the terminal may send the SRS on the M SRS resources in a non-frequency hopping manner.

Optionally, whether the terminal transmits the SRS in a frequency hopping manner depends on whether there is at least one SRS resource configuration information in the M pieces of SRS resource configuration information that satisfies a preset condition. That is, when at least one SRS resource configuration information of the M pieces of SRS resource configuration information satisfies the preset condition, the terminal sends the SRS in a frequency hopping manner. Alternatively, when none of the M pieces of SRS resource configuration information meets the preset condition, the terminal uses a non-frequency hopping manner to send the SRS.

Exemplarily, in the NR system, for one SRS resource configuration information, the preset condition is: b _hop is smaller than B _SRS .

Optionally, when the terminal transmits the SRS in a frequency hopping manner on the M SRS resources, the frequency hopping times of the SRS in one frequency hopping period is equal to the sum of the respective frequency hopping times corresponding to the M SRS resources. It should be understood that the frequency hopping times corresponding to one SRS resource is determined according to the SRS resource configuration information corresponding to the SRS resource.

It should be understood that

Frequency hopping times determined for the mth SRS resource configuration information.

Among them, m is a positive integer greater than or equal to 1 and less than or equal to M. B _SRS,m is the symbol bandwidth parameter in the mth SRS resource configuration information, and b _hop,m is the configuration bandwidth parameter in the mth SRS resource configuration information. N _b,m is determined according to _CSRS,m and b lookup Table 1. C _SRS,m is the bandwidth set parameter in the mth SRS resource configuration information.

For example, the network device sends 2 pieces of SRS resource configuration information to the terminal. Wherein, in the first SRS resource configuration information, C _SRS =9, B _SRS =2, and b _hop =1. Therefore, based on Table 1, the number of frequency hopping determined by the first SRS resource configuration information is equal to 2. In the second SRS resource configuration information, C _SRS =9, B _SRS =2, and b _hop =0. Therefore, based on Table 1, the number of frequency hopping determined by the second SRS resource configuration information is equal to four. Therefore, the number of frequency hopping of the SRS in one frequency hopping period is equal to 6.

Optionally, the terminal sends the SRS on the M SRS resources in a frequency hopping manner, and the following manner 1 or manner 2 may be adopted. Among them, the first mode can also be called an independent frequency hopping mode. The second method can also be called the overall frequency hopping method.

Manner 1: The terminal determines the arrangement order of the M SRS resources. Afterwards, the terminal transmits the SRS on the M SRS resources in a frequency hopping manner according to the arrangement order of the M SRS resources.

Exemplarily, the terminal sends the SRS on the M SRS resources in a frequency hopping manner according to the arrangement order of the M SRS resources, including the following steps S20-S23.

S20, set i=0.

S21. The terminal sends the SRS on the i-th SRS resource in a frequency hopping manner.

Based on step S21, the SRS may cover the entire frequency domain resource occupied by the i-th SRS resource.

S22, set i=i+1.

S23. When i≤N, execute step S21; when i>N, execute step S20.

Exemplarily, referring to FIG. 11 , the network device sends SRS resource configuration information #1 and SRS resource configuration information #2 to the terminal, where SRS resource configuration information #1 is used to determine SRS resource #1, and SRS resource configuration information #2 is used to determine SRS resource #2. In a frequency hopping cycle, the terminal first transmits the SRS on the SRS resource #1 in a frequency hopping manner. After that, the terminal transmits the SRS on the SRS resource #2 in a frequency hopping manner.

Optionally, the terminal determines the arrangement order of the M SRS resources, and can adopt any one of the following methods:

(1) When the SRS resource configuration information further includes an index of the SRS resource, the terminal determines the arrangement order of the M SRS resources according to the index of each SRS resource in the M SRS resources.

In a possible design, the terminal arranges the M SRS resources in ascending order according to the indices of the SRS resources, and determines the arrangement order of the M SRS resources.

Based on this design, the smaller the index, the smaller the sequence number of the SRS resource in the arrangement order.

In another possible design, the terminal arranges the M SRS resources in descending order according to the indexes of the SRS resources, and determines the arrangement order of the M SRS resources.

Based on this design, the smaller the index, the larger the sequence number of the SRS resource in the arrangement order.

(2) The terminal determines the arrangement order of the M SRS resources according to the frequencies of the M SRS resources.

It should be understood that the frequency of the SRS resource is the frequency of the frequency domain resource occupied by the SRS resource in the frequency domain.

In a possible design, the terminal arranges the M SRS resources in order of frequency from low to high, and determines the order of the M SRS resources.

Based on this design, SRS resources with lower frequencies have lower sequence numbers in the arrangement order.

In another possible design, the terminal arranges the M SRS resources in descending order of frequency, and determines the arrangement order of the M SRS resources.

Based on this design, the SRS resource with higher frequency has a smaller sequence number in the arrangement order.

Manner 2: The terminal determines the frequency hopping pattern according to the M pieces of SRS resource configuration information. After that, the terminal transmits the SRS in a frequency hopping manner on the M SRS resources according to the frequency hopping pattern.

Optionally, the frequency hopping pattern may be determined according to the following manner: for the ith SRS resource in the M SRS resources, the terminal determines the frequency hopping number P _i corresponding to the ith SRS resource according to the configuration information of the ith SRS resource. ; Then, the terminal divides the frequency domain resources occupied by the ith SRS resource into P _i subbands according to the frequency hopping times P _i corresponding to the ith SRS resource. In this way, the terminal can determine P subbands,

In a possible design, when the frequency hopping times corresponding to the M SRS resources are all the same, the terminal may arrange the P subbands in a tree structure to generate a frequency hopping pattern.

Exemplarily, referring to FIG. 12( a ), the network device sends SRS resource configuration information #1 and SRS resource configuration information #2 to the terminal. SRS resource configuration information #1 is used to determine SRS resource #1, and SRS resource configuration information #2 is used to determine SRS resource #2. The frequency hopping times determined by the SRS resource configuration information #1 and the SRS resource configuration information #2 are both 2. Therefore, SRS resource #1 may be divided into subband #1 and subband #2 in the frequency domain, and SRS resource #2 may be divided into subband #3 and subband #4 in the frequency domain. Subbands #1 to #4 are arranged in a tree structure. Therefore, at the first transmission occasion, the terminal transmits the SRS on subband #1. At the second transmission occasion, the terminal transmits the SRS on subband #3. At the third transmission occasion, the terminal transmits SRS on subband #2. At the fourth transmission occasion, the terminal transmits the SRS on subband #4.

For the related concept of the sending timing, reference may be made to the above description, and details are not repeated here.

In another possible design, when the frequency hopping times corresponding to the M SRS resources are different, the terminal may arrange the P subbands according to a preset rule to generate a frequency hopping pattern. The preset rule is used to make the P subbands discretely distributed.

Exemplarily, referring to FIG. 12(b), the network device sends SRS resource configuration information #1 and SRS resource configuration information #2 to the terminal. SRS resource configuration information #1 is used to determine SRS resource #1, and SRS resource configuration information #2 is used to determine SRS resource #2. The frequency hopping times determined by the SRS resource configuration information #1 are both 2. The frequency hopping times determined by the SRS resource configuration information #2 are all four. SRS resource #1 can be divided into subband #1-1 and subband #1-2 in the frequency domain, and SRS resource #2 can be divided into subband #2-1, subband 2-2, Subband 2-3, and Subband #2-4. The above-mentioned subbands are arranged according to preset rules to generate a frequency hopping pattern. Therefore, at the first sending occasion, the terminal sends SRS on subband #1-1; at the second sending occasion, the terminal sends SRS on subband #2-1; at the third sending occasion, the terminal sends SRS on subband #2-1 #1-2 sends SRS; at the fourth sending occasion, the terminal sends SRS at subband #2-2; at the fifth sending occasion, the terminal sends SRS at subband #2-3; at the sixth sending occasion, The terminal transmits SRS in subbands #2-4.

Based on the second method, there are K groups of sending opportunities in a frequency hopping period that meet a preset condition, and any group of sending opportunities in the K groups of sending opportunities includes two adjacent sending opportunities, and the preset condition is: adjacent The subbands occupied by the SRS sent on the two sending occasions respectively belong to different SRS resources in the M SRS resources in the frequency domain, and K is a positive integer greater than or equal to M.

Taking Figure 12(b) as an example, in a frequency hopping period, the SRS sent at the first sending occasion occupies subband #1-1, and the SRS sent at the second sending occasion occupies subband #2-1. Band #1-1 and subband #2-1 respectively belong to different SRS resources in the frequency domain. Therefore, the first transmission occasion and the second transmission occasion constitute a group of transmission occasions that satisfy the preset condition.

Taking Fig. 12(b) as an example, there are 3 groups of sending timings within one frequency hopping period that meet the preset conditions. The three sets of transmission timings are respectively {first transmission timing, second transmission timing}, {second transmission timing, third transmission timing}, and {third transmission timing, fourth transmission timing}.

It should be understood that using the frequency hopping method of the second method can ensure that the network device can quickly obtain channel information in a wide range in the frequency domain, which is beneficial for the network device to quickly obtain the channel information of the full bandwidth. Taking Figure 12(b) as an example, the network device obtains the channel information of subband #1-1 and subband #2-1 after two frequency hopping, and subband #1-1 and subband #2-1 are on the entire bandwidth. The distribution is relatively scattered, which is beneficial for the network device to estimate the channel information of the full bandwidth by means of interpolation or extrapolation.

S205, the network device receives the SRS sent by the terminal on the M SRS resources.

Optionally, when the terminal sends the SRS in the frequency hopping manner on the M SRS resources, the network device receives the SRS sent by the terminal in the frequency hopping manner on the M SRS resources. Alternatively, when the terminal transmits the SRS in the non-frequency hopping manner on the M SRS resources, the network device receives the SRS transmitted by the terminal in the non-frequency hopping manner on the M SRS resources.

Optionally, for the network device to receive the SRS sent by the terminal in a non-frequency hopping manner on the M SRS resources, the following manner 1 or manner 2 may be adopted.

Manner 1: The network device determines the arrangement order of the M SRS resources. After that, the network device sequentially receives the SRS sent by the terminal in the frequency hopping manner on the M SRS resources according to the arrangement order of the M SRS resources.

Manner 2: The network device determines the frequency hopping pattern according to the M pieces of SRS resource configuration information. After that, the network device receives the SRS sent by the terminal in the frequency hopping manner on the M SRS resources according to the frequency hopping pattern.
