FIG. 1 is a system architecture diagram to which the embodiments of the present application are applied. As shown in the figure, the mobile communication system includes a core network device 140, a radio access network device 130, and at least one terminal device (such as the terminal device 120 and the terminal device in FIG. 1). device 110). The terminal device is connected to the wireless access network device by wireless, and the wireless access network device is connected to the core network device by wireless or wired. The core network device and the radio access network device can be independent and different physical devices, or the functions of the core network device and the logical functions of the radio access network device can be integrated on the same physical device, or they can be one physical device. It integrates the functions of some core network equipment and some functions of the wireless access network equipment. Terminal devices can be either fixed or mobile. Fig. 1 is only a schematic diagram, the communication system may also include other network devices, such as wireless relay devices and wireless backhaul devices, which are not shown in Fig. 1 . The embodiments of the present application do not limit the number of core network devices, wireless access network devices, and terminal devices included in the mobile communication system.

At present, if the information transmission of the terminal equipment is limited to the bandwidth part or the range of the channel bandwidth supported by the terminal equipment, and the BWP or the channel bandwidth is narrow, the information transmission cannot better obtain the frequency diversity gain. Also, if too many users transmit in the same BWP, the network will be congested, and the time delay for users to transmit information will increase. Therefore, the network device can schedule resources beyond the frequency range supported by the BWP or the terminal device, and perform information transmission with the terminal device, which can effectively avoid interference or achieve load balancing.

Usually, when the terminal device wants to transmit information, if the frequency range of the subsequent information transmission and the frequency range of the current information transmission exceed the maximum channel bandwidth of the terminal device (for example, exceed the BWP supported by the terminal device), the terminal device needs to pass the frequency Tune into new frequency domain resources to transmit information. In this specification, for simplicity, the following frequency tuning is simply referred to as tuning.

BWP can be understood as a kind of bandwidth resource, and it can also be understood as a kind of resource. The network device configures at least one BWP resource for the end user, and each BWP resource has a corresponding BWP identification ID. The network device can configure relevant parameters for each BWP separately. For example, the BWP-related parameters include at least one of BWP starting position, BWP size, subcarrier spacing, control channel resource set, data transmission configuration, DMRS configuration, and the like. For example, for different BWPs or different BWPIDs, the network may configure different BWP IDs and BWP-related parameters.

As described above, each BWP corresponds to an identity, and each BWP is configured with respective radio resource control (radio resource control, RRC) parameters related to transmission. If the information is transmitted on the new BWP, the parameters associated with the new BWP need to be applied on the terminal device. This will bring a large handover delay, and because information transmission cannot be performed during the handover period, it will cause problems such as transmission interruption and increased data transmission delay.

Therefore, how the network device instructs the information transmission mode of the terminal device according to the service requirements of the terminal device has become a technical problem that needs to be solved at present.

The present application provides a communication method, in which the network device can flexibly instruct the terminal device's information transmission method according to the service requirements of the terminal device, and can obtain frequency domain diversity gain and load balance, improve the reliability of information transmission and reduce the transmission delay.

In this application, the bandwidth supported by the terminal device may be the channel bandwidth supported by the terminal device, or the maximum channel bandwidth supported by the terminal device, or the number of resource blocks supported by the terminal device, or the maximum resource block (resource block) supported by the terminal device. , RB) number.

The embodiments of the present application can be applied to downlink signal transmission, uplink signal transmission, and device to device (device to device, D2D) signal transmission. For downlink signal transmission, the sending device is a wireless access network device, and the corresponding receiving device is a terminal device. For uplink signal transmission, the sending device is a terminal device, and the corresponding receiving device is a wireless access network device. For D2D signal transmission, the sending device is a terminal device, and the corresponding receiving device is also a terminal device. The embodiment of the present application does not limit the transmission direction of the signal. It should be understood that "information transmission" herein can be sending information or receiving information.

In this application, the position may be a starting position, or a starting resource block (RB), or a sequence number of a starting resource, or a sequence number of a starting resource block, or a starting position and length. It should be noted that the locations in this application may include default locations and/or additional locations. That is, the BWP in this application may be configured to include one or more locations. When BWP configures a location, that location is the default location. The default location is configured in the same way as in the existing protocol. The configuration of the default location is determined by configuring the starting resource location of the BWP and the number of frequency domain resources included in the BWP. The default location described in this application can be understood as the sequence number of the starting RB of the only BWP configured for the BWP in the existing protocol. When BWP configures n locations, one default location and (n-1) additional locations are included. Among them, the first position is the default position, or the position with serial number 0 is the default position. Positions other than the first position are additional positions, or positions with a sequence number other than 0 are additional positions. The additional location information may be the sequence number of the additional location, or the starting resource location of the additional location, or the sequence number of the starting resource location of the additional location. where n is an integer greater than 1.

In this application, the frequency range of the BWP is the bandwidth of the BWP, or the number of RBs included in the BWP, or the channel bandwidth supported by the terminal device, or is composed of one or more RBs. The frequency range of the BWP includes the default frequency range and/or the additional frequency range. The default frequency range is the frequency range determined by the default position and BWP length. The default frequency range is configured in the same way as in existing protocols. The additional frequency range is the frequency range determined by the additional position as the starting position and the BWP length. In this application, the size of BWP can also be understood as the frequency range of BWP.

In this application, the tuning time may be predefined, or the tuning time may be configured or indicated by the base station. For example, the tuning time can be predefined. The tuning time is 140 μs, or 210 μs, or 280 μs. For example, the tuning time may also be determined according to UE capabilities. When the shortest supported tuning time reported by the UE is 140 μs, the tuning time should be greater than or equal to 140 μs. For another example, the tuning time is configured or indicated by the base station. For example, the tuning time indicated by the base station may be any one of 70 μs, 140 μs, 210 μs, 280 μs, and 560 μs.

In this application, the processing duration may also be understood as processing delay, or processing time. For example, handover duration and handover time, handover delay can be interchanged.

In this application, the first BWP is the BWP activated by the terminal device, or the initial BWP of the terminal device, or the BWP currently applied by the terminal device, or the BWP where the terminal device receives the first signaling. The second BWP is a candidate BWP of the terminal device, or an inactive BWP, or a target BWP of the terminal device, or a BWP after the terminal device performs frequency domain resource switching, or a BWP different from the first BWP. The new BWP is a different BWP from the first BWP.

For the convenience of distinction and description, the three information transmission modes involved in this application are distinguished by "mode 1", "mode 2", and "mode 3".

Way 1:

Mode 1 in this application is frequency hopping, and the frequency hopping transmission requires frequency tuning. For example, mode 1 is frequency hopping outside BWP (outside BWP FH), or frequency hopping between BWPs, or at least one hop in multiple frequency hopping transmissions is outside BWP, or at least two frequency hopping transmissions in multiple frequency hopping transmissions. The frequency offset between hops is greater than the bandwidth supported by the end device. When the terminal equipment uses Mode 1 for information transmission, at least two frequency tunings are required. The frequency tuning time of mode 1 may be referred to as the first processing duration or the first interruption duration. For mode 1, the terminal device determines the second frequency domain resource and/or the frequency hopping offset for information transmission, and determines the first frequency domain resource according to the second frequency domain resource and the frequency hopping offset. After the terminal device tunes from the second frequency domain resource to the first frequency domain resource for information transmission, the terminal device needs to tune back to the first frequency domain resource again. For example, the second frequency domain resource is within the frequency range of the BWP, or all the resources in the first frequency domain resource are within the frequency domain range of the BWP. The first frequency domain resource is outside the frequency range of the BWP, or at least some of the first frequency domain resources are outside the frequency domain range of the first BWP. For example, the information in this application is the information carried by the physical uplink shared channel, or the information carried by the physical uplink control channel, or the information carried by the physical downlink shared channel.

As shown in (a) of Fig. 2, when the terminal device uses Mode 1 to transmit information, two tunings are required, that is, there are two tuning times. The terminal device tunes from the first resource to the second resource for information transmission, and after the information transmission, the terminal device tunes back to the first resource again. For example, when the terminal device uses Mode 1 to transmit information, all RRC parameters related to the BWP ID remain unchanged. For example, when the terminal device uses Mode 1 to transmit information, at least other parameters other than the first characteristic parameter are not updated in the RRC parameters related to the BWP ID. The first characteristic parameter includes one or more of parameters of BWP ID parameter, BWP location and BWP size, and subcarrier spacing. Other parameters other than the first characteristic parameter include one or more of bandwidth, subcarrier spacing, control channel resource set, and DMRS configuration.

In the present application, the method for indicating the frequency hopping offset in Mode 1 may be at least one of the following: 1) It may be indicated by a second offset value, and the BWP ID and BWP position remain unchanged. 2) The BWP ID remains unchanged and is determined according to the location of the BWP. 3) Determined according to BWP ID information. The specific instruction method will be described in detail in the following embodiments.

Way 2:

Mode 2 in this application refers to the transmission of information according to the location of the BWP. When a new BWP location is indicated to the terminal device, the terminal device determines the BWP resource according to the new BWP location, tunes the frequency to the new BWP resource, and transmits information on the BWP resource. For mode 2, after the terminal device performs information transmission on the BWP resource determined by the new BWP location, it continues to perform downlink reception or uplink transmission of other information on the BWP resource. As shown in (b) of Figure 2, when the terminal device uses Mode 2 to transmit information, one tuning is required. When the terminal device uses Mode 2 to transmit information, at least other parameters except the first characteristic parameter in the RRC parameters related to the BWP ID are not updated. For example, the first characteristic parameter includes one or more of a BWP ID parameter, a parameter indicating a BWP start, and a BWP size. Therefore, when the second tuning mode is applied, the processing time required by the terminal device is also the first processing duration or the first interruption duration. In the existing BWP handover, the BWP handover delay required by the terminal device is called the second processing duration. The first processing duration is shorter than the second processing duration. Therefore, the service interruption time of Mode 2 is shorter, and the impact on the service is smaller. And when the terminal device uses Mode 2 for transmission, the terminal device can determine the location of the BWP resource according to the additional location of the BWP.

In this application, the location of the terminal device BWP can be indicated by at least one of the following methods: 1) The BWP ID information remains unchanged, indicating the location of the BWP. 2) Indicate the BWP ID information, only the location information corresponding to the BWP ID is applied, and the RRC parameters related to the BWP are not applied. 3) The BWP ID information remains unchanged, indicating the offset information of the BWP location. The specific instruction method will be described in detail in the following examples.

Way 3:

Mode 3 in this application is BWP handover. When the terminal device is indicated with new BWP ID information, the terminal device determines the BWP resource according to the new BWP ID, tunes the frequency to the new BWP resource, and transmits information on the BWP resource. When the terminal device uses Mode 3 to transmit information, the BWP location adopts the default location (default). When the BWP is switched, the second processing duration is relatively long, such as 1 time slot (slot) or 3 time slots. When the information transmission is performed in the way of BWP handover, the terminal device applies (or updates, or loads) all the parameter information related to the new BWP ID.

For example, when the terminal device uses Mode 3 to transmit information, the BWP ID information may be indicated by the difference between the first BWP ID and the second BWP ID. The BWP ID indication may be the difference between the second BWP ID and the first BWP ID. And take the modulo of the difference according to the configured maximum number of BWP IDs. For example, the maximum number of BWP IDs is 4, the ID of the first BWP is 1, and the ID of the second BWP is 2. Then the BWPID is indicated as mod(2-1,4)=1. For example, the BWP ID information may be the sequence number after excluding the first BWPID according to the order of the configured BWP IDs. For example, the maximum number of BWP IDs is 4, the ID of the first BWP is 1, and the ID of the second BWP is 2. The order of the configured BWP IDs is 0, 1, 2, 3; the order after excluding the first BWP ID is 0, 2, 3; the second BWP ID is 2, which is the second ID in the new order. The sequence number is 1. The BWP ID is indicated as 1. Of course, as mentioned above, when the terminal device adopts other transmission modes, the BWP ID or BWP ID information may also be used to indicate the BWP location information or frequency hopping location information, and the method described here is also applicable.

In this application, the offset of the frequency hopping within the BWP may be the first offset value.

It should be noted that, in the present application, a mode of performing frequency hopping transmission in the BWP when the BWP location of the terminal device changes may also be supported. That is, the terminal device transmits information according to Mode 2, and frequency hopping within the BWP. For example, the terminal device can determine the BWP resource according to the additional location of the BWP, and can perform frequency hopping within the BWP resource.

It should be noted that, in the present application, a manner in which the terminal device performs frequency hopping transmission after BWP handover can also be supported. That is, the terminal device performs information transmission according to Mode 3 and frequency hopping within the BWP. For example, the terminal device can determine the BWP resource according to the new BWP ID information, and can perform frequency hopping within the new BWP resource.

In this application, in order to obtain frequency diversity gain, one data transmission can be divided into multiple frequency hopping transmissions or repeated transmissions in time. The frequency domain resources corresponding to each segment or each transmission are not exactly the same. Each segment or transmission is a one-hop transmission in a frequency-hopping transmission. Any hop refers to any one transmission or any segment of transmission among multiple frequency hopping transmissions included in one data transmission. The corresponding resources refer to the resources occupied or used by data transmission. The per-hop resources for frequency hopping transmissions may be resources that are all within the BWP. The frequency hopping transmission may also have at least one hop outside the BWP. If a frequency hopping transmission is outside the BWP, frequency tuning needs to be performed, and the frequency domain resource is mode 1.

In the present application, during frequency hopping, the frequency offset between two hops is the difference between the positions of the two hops, or the number of RBs that differ between the starting positions of the two hops. For example, the frequency domain resources of the first hop are the 10th to 19th RBs, and the frequency offset between the two hops is 50 RBs. The frequency domain resources of the second hop are 10~19RB+50RB=60~69RB, the frequency domain resources of the third hop are 10~19RB+50RB*2=110~119RB, and the frequency domain resources of the fourth hop are 10~19RB +50RB*3=160～169RB. The schematic diagrams of frequency hopping are shown in Figure 2(c) and Figure 2(d). Wherein, (c) in FIG. 2 is a schematic diagram of frequency hopping within the BWP. Taking the PUCCH in (c) of Fig. 2 as an example, the frequency offset 1 between PUCCH1 and PUCCH2 is the frequency offset between two hops. The frequency domain resources of the two hops are all within the BWP. (d) in FIG. 2 is a schematic diagram of BWP external frequency hopping. Taking the PUCCH in (d) of Fig. 2 as an example, the frequency offset 2 between PUCCH1 and PUCCH2 is the frequency offset between two hops. Because the frequency domain resources of the second hop (PUCCH2) are outside the BWP, the frequency hopping is outside the BWP.

As mentioned above, this application can be applied to D2D scenarios. That is, the originating device may be a network device or a terminal device. It should be noted that, in the following embodiments, only a network device is used as an example for description, and this application does not make any limitation on the originating device.

Fig. 3 is a schematic block diagram of a communication method 300 of the present application, and the method shown in Fig. 3 includes S301 to S302. Each step is described in detail below.

Step S301, the network device sends the first signaling to the terminal device.

In this application, the first signaling may be downlink control information (DCI), radio resource control (Radio Resource Control, RRC) signaling, or a media access control entity (media access control control entity). element, MAC CE) signaling. The first signaling may be a field, or part of bits in a field, or an information element, or control information, or indication information.

Step S302, the terminal device receives the first signaling within the frequency range of the first BWP, and determines the information transmission mode.

The description of the method is as described above, and will not be repeated here.

Further, the terminal device may communicate according to the indication of the first signaling. Specifically, the terminal device may receive the first signaling within the frequency range of the first BWP, determine the information transmission mode, and communicate according to the determined transmission mode.

In a possible implementation manner, the first signaling indicates the second frequency offset information or the offset value used when the BWP is out-hopped or the position when the BWP is out-hopped. The terminal equipment transmits information according to Mode 1. For example, the terminal device determines the first frequency domain resource according to the second frequency offset information and/or the second frequency domain resource. And at least some of the resources in the first frequency domain are outside the frequency range of the first BWP. The terminal device performs communication in the first frequency domain resource by frequency tuning. That is, the first signaling may instruct the terminal device to perform frequency hopping transmission outside the first BWP by frequency tuning. The terminal device performs information transmission on the first frequency domain resource according to Mode 1. All parameters corresponding to the first BWP of the terminal device remain unchanged.

In this application, "the first BWP" does not change, it can be understood that the ID of the first BWP does not change, or that only the first parameter set in the related parameters of the first BWP, at least other parameters except the first characteristic parameter are not updated. . It can also be understood that the BWP used by the terminal device before and after information transmission or when the UE communicates is the first BWP.

For example, the second frequency offset information is one or more offset values. This offset value is used for frequency hopping outside the BWP. For example, the offset value of the frequency hopping outside the BWP is the offset value of the frequency domain resources of two hops in the frequency hopping transmission, or the frequency offset value of the position of the two hops in the frequency hopping transmission, or the two hops in the frequency hopping transmission. The frequency offset value between . For example, the unit of the offset value is RB, or Hz, or MHz, or kHz, or a resource block group (resource block group, RBG), or a resource unit composed of multiple RBs. For example, when the bandwidth of the BWP is 20 MHz, the BWP outer frequency hopping offset value is at least one of 20 MHz, 40 MHz, 60 MHz, and 80 MHz. For example, when the number of RBs included in the BWP is 106, the offset value of the frequency hopping outside the BWP is at least one of 100, 150, 200, and 250.

For example, when the terminal device performs frequency hopping transmission according to Mode 1, the used offset value is obtained from the second frequency offset information. For example, the second offset information may be pre-specified or indicated by the network device. For example, the network device may configure N1 candidate offset values for the terminal device. Among them, N1 is a positive integer. For example, N1=4. For example, N1=2. When the terminal equipment performs frequency hopping transmission according to Mode 1, the first signaling indicates which offset value in N1 to use.

For example, when the terminal device performs frequency hopping transmission according to Mode 1, the used offset value is obtained from the information corresponding to the BWP ID. For example, the offset value is the position corresponding to the BWP ID, or the length corresponding to the BWP ID. For example, the position corresponding to the BWPID indicated by the first signaling is the 100th RB, and the offset value is 100 RBs. For example, the length corresponding to the BWP ID indicated by the first signaling is 106 RBs, and the offset value is 106 RBs. For example, the network device may be configured with N3 BWPs for the terminal device. Among them, N3 is a positive integer. For example, N3=4. For example, N3=2.

For example, when the terminal device performs frequency hopping transmission according to Mode 1, the used offset value is obtained from the location information of the BWP. For example, the offset value is a value corresponding to the position of the BWP. For example, the BWP location indicated by the first signaling is the default location, the default location of the BWP is the 100th RB, and the offset value is 100 RBs. For example, the BWP position indicated by the first signaling is the second additional position, and the position is the 250th RB, and the offset value is 250 RBs.

For example, when the terminal device performs frequency hopping transmission according to Mode 1, the location of the frequency hopping transmission outside the BWP is obtained through the information corresponding to the BWPID. For example, the location of the frequency hopping transmission is the location corresponding to the BWP ID, or the length corresponding to the BWP ID. For example, the position corresponding to the BWP ID indicated by the first signaling is the 100th RB, and the starting position of the frequency hopping transmission is the 100th RB. For example, the length corresponding to the BWP ID indicated by the first signaling is 106 RBs, and the starting position of the frequency hopping transmission is the 106th RB. For example, the network device may configure N3 BWPs for the terminal device. Among them, N3 is a positive integer. For example, N3=4. For example, N3=2.

For example, when the terminal device performs frequency hopping transmission according to Mode 1, the location of the frequency hopping transmission outside the BWP is obtained through the location information of the BWP. For example, the location of the frequency hopping transmission is a value corresponding to the location of the BWP. For example, the BWP location indicated by the first signaling is the default location, the default location of the BWP is the 100th RB, and the location of the frequency hopping transmission is the 100th RB. For example, the BWP position indicated by the first signaling is the second additional position, and the position is the 250th RB, then the position of the frequency hopping transmission is the 250th RB.

In the present application, when the terminal equipment performs frequency hopping transmission that needs to be tuned, it can perform information transmission in a larger range of frequency domain resources, and can obtain better diversity gain. Also, no change of BWP position or switching of BWP is required to obtain diversity gain. At this time, the BWP ID remains unchanged, so the RRC parameters related to the BWP ID remain unchanged, or at least other parameters in the RRC parameters except the first characteristic parameter are not updated. Therefore, only the frequency tuning time is required. Compared with the BWP handover, the interruption time of the user information transmission is shorter and the impact is smaller.

In a possible implementation manner, the first signaling indicates location information of the first BWP. The terminal device determines the BWP resource according to the location information of the first BWP. The terminal device transmits information according to Mode 2.

For example, when the first BWP location configured by the network device for the terminal device includes an additional location, the terminal device determines the additional frequency range according to the additional location information indicated by the first signaling. Tune into the additional frequency range of the first BWP for information transmission.

For example, when the network device configures multiple locations for the first BWP of the terminal device, the first signaling indicates location information of the BWP. The plurality of locations includes a default location and at least one additional location. For example, the frequency range corresponding to the default position is the default frequency range. The frequency range corresponding to the first additional position is the first additional frequency range. The frequency range corresponding to the second additional position is the second additional frequency range. For example, when the first signaling indicates the first additional location, the terminal device can tune from the default frequency range to the first additional frequency range, or the terminal device can tune from the second additional frequency range to the first additional frequency range. For example, when the first signaling indicates the default location, the terminal device can tune from the first additional frequency range to the default frequency range, or the terminal device can tune from the second additional frequency range to the default frequency range.

For example, the location information of the BWP is obtained based on the BWP ID. For example, the first signaling indicates BWP ID information, and the location information of the BWP is the location corresponding to the BWP ID, or the length corresponding to the BWP ID. For example, if the starting position corresponding to the BWP ID indicated by the first signaling is the 100th RB, the starting position of the BWP is the 100th RB. For example, the length corresponding to the BWP ID indicated by the first signaling is 106 RBs, and the starting position of the BWP is the 106th RB.

For example, the location information of the BWP is acquired according to the BWP offset information. For example, the BWP offset information is the second offset information. The terminal device determines the location of the first BWP according to the second offset information. For example, the first signaling indicates the second offset information, and the terminal device determines the new location of the first BWP according to the second offset information and the location of the first BWP. For example, the second offset information indicated by the first signaling is 100 RBs, and the default position of the first BWP is the 100th RB. Then the position of the first BWP is changed to (100+100)=200th RB.

When the first signaling indicates the location information of the BWP, the terminal device does not expect a frequency hopping indication beyond the frequency range of the first BWP. For example, when the terminal device transmits information according to Mode 2, it will not perform BWP out-of-frequency hopping transmission at the same time. That is to say, in this application, the terminal device does not support Mode 1 and Mode 2 at the same time.

In this application, when a large number of services need to be transmitted within the range of the first BWP location, which leads to resource shortage and network congestion, the method of changing the location of the first BWP can be used to allocate different users to different resources to achieve load balanced. Moreover, at this time, the BWP ID does not change, so in the RRC parameters related to the BWP ID, at least other parameters except the first characteristic parameter are not updated. Therefore, the change time of the resource location is short, if only the tuning time is required, the interruption time of the user information transmission is shorter than that of the BWP handover, and the impact is smaller.

In a possible implementation manner, when the first signaling indicates the identification ID information of the second BWP, the terminal device determines the BWP resource according to the first BWP ID. Information transmission is performed on the BWP resource according to Mode 3.

When the first signaling indicates the second BWP ID information, the terminal device does not expect a frequency hopping indication beyond the frequency range of the second BWP. For example, when the terminal device transmits information according to Mode 3, it will not perform BWP out-of-frequency hopping transmission at the same time. That is to say, in this application, the terminal device does not support Mode 1 and Mode 3 at the same time.

It should be noted that a situation of "unexpected by the terminal device" here can be understood as the terminal device does not support this situation, or the terminal device does not do any processing after encountering this situation, or does not perform information transmission after the terminal device encounters this situation. , or because the terminal device decides how to deal with it after encountering the situation (the network device does not impose restrictions or regulations), or because the terminal device thinks that the scheduling of the network device will not occur, or the scheduling of the network device cannot occur in this situation.

In this application, the network device may configure multiple BWPs for the terminal device, and each BWP is configured with a corresponding BWP ID and BWP location. The network device can indicate whether the BWP of the terminal device is changed by means of signaling indication. If the BWP ID indicated by the network device is the same as the BWP ID currently applied by the terminal device, the terminal device does not need to update the BWP location and BWP configuration. If the BWP ID indicated by the network device is different from the BWP ID currently applied by the terminal device, the terminal device applies the new BWP ID, applies the new BWP location, and applies the new BWP configuration.

It should be understood that the BWP handover can not only change the position of the BWP, but also change the relevant configuration parameters of the BWP, which is suitable for the change of the user's business requirements. For example, from upstream service-based to downstream service-based, for example, the requirement for data rate is reduced or increased. For information transmission in this case, there is no need to obtain a greater frequency diversity gain than within the BWP bandwidth, so there is no need to support frequency hopping transmission outside the BWP at this time.

For example, when the first signaling indicates the additional location of the first BWP, the BWP resource is determined according to the additional location of the first BWP. Information transmission is performed on the BWP resource according to Mode 2. The resources of the first BWP may be changed from the default frequency range to the additional frequency range, or may be changed from the first additional frequency range to the second additional frequency range.

For example, when the first signaling indicates the default location of the first BWP, the terminal device determines the BWP resource according to the additional location of the first BWP. The information is transmitted according to 2 on the BWP resource. The resources of the first BWP may be changed from the additional frequency range to the default frequency range, or may be unchanged within the default frequency range.

For example, the first signaling indicates the second frequency offset of the frequency hopping communication, and the terminal device determines the first frequency domain resource according to the second frequency offset. And when at least some of the resources in the first frequency domain are outside the frequency range of the first BWP, the terminal device performs information transmission in the first frequency domain resource according to Mode 1.

For example, when the first signaling indicates the ID of the second BWP, the terminal device determines the BWP resource according to the location information corresponding to the BWP ID. Information transmission is performed according to mode 3 on the BWP (second BWP) resource. The resources of the second BWP are determined according to the default location of the second BWP.

According to the communication method provided by the present application, the network device can flexibly instruct the information transmission mode of the terminal device according to the service requirements of the terminal device, and can obtain frequency domain diversity gain and load balance to ensure the reliability of information transmission.

In this application, the terminal device can transmit in different ways according to the resource determined by the first signaling, which will be described in detail below.

As an example, it is assumed that the number of BWP IDs configured by the network device is N1, that is, the number of candidate IDs that can be configured in mode 3 is N1. The number of candidate positions in Mode 1 is N2. The number of candidate positions in Mode 2 is N3. The number of offset values for frequency hopping within the BWP is N4. Wherein, N1, N2, N3 and N4 are all integers greater than 0.

In a possible implementation manner, the first signaling can indicate at least one of the following: {location information of the first BWP and frequency hopping disabled}; {ID information of the second BWP and frequency hopping disabled}; {Location information and first frequency offset information of the first BWP}; {ID information and first frequency offset information of the second BWP}; Second frequency offset information.

In a possible implementation manner, because no frequency hopping does not need to additionally indicate the frequency hopping offset in the BWP, or it can be considered that the frequency hopping offset value is 0, the content that can be indicated by the first signaling can be simplified. The first signaling can indicate at least one of the following: {location information of the first BWP}; {ID information of the second BWP}; {location information and first frequency offset information of the first BWP}; {the location information of the second BWP} ID information and first frequency offset information}; second frequency offset information.

For example, when the first signaling indicates the location information of the first BWP and frequency hopping is disabled, the BWP resource is determined according to the location information of the first BWP. Information transmission is performed on the BWP resource according to Mode 2.

The offset value of the frequency hopping in the BWP is determined according to the first frequency offset information. Information transmission is performed on BWP resources according to mode 3, and frequency hopping is performed within the BWP.

For example, when the first signaling indicates the second frequency offset information, the BWP outer frequency hopping offset value is determined according to the second frequency offset information. The frequency hopping resource used for transmission is determined according to the second frequency offset information. Information transmission is performed on the frequency hopping resource according to Mode 1.

In a possible implementation manner, the first signaling can indicate at least one of the following: {location information of the first BWP}; {ID information of the second BWP}; first frequency offset information; second frequency offset information.

In a possible implementation manner, the terminal device receives sixth information, where the sixth information is used to indicate a manner of information transmission. The terminal device determines the content of the indication of the first signaling according to the sixth information. The content indicated by the first signaling corresponds to the transmission mode indicated by the sixth information, or the first signaling indicates frequency domain resource switching information corresponding to the transmission mode. The terminal device determines the frequency domain resources for information transmission according to the indicated transmission mode and the frequency domain resource switching information corresponding to the mode. And transmit information on the resource according to the indicated transmission mode. For example, the transmission modes that can be indicated by the sixth information may be the aforementioned mode 1, mode 2, mode 3, {mode 2 and intra-BWP frequency hopping}, {mode 3 and intra-BWP frequency hopping}, intra-BWP frequency hopping, no At least one of frequency hopping and frequency tuning. The non-frequency tuning may be frequency hopping in the BWP, or no frequency hopping. For example, the frequency domain resource switching information includes at least one of BWP ID information, BWP location information, BWP outer frequency hopping offset information, BWP inner frequency hopping offset information, and non-frequency hopping.

For example, the transmission mode that can be indicated by the sixth information is at least one of mode 1, mode 2, mode 3, {mode 2 and intra-BWP frequency hopping}, {mode 3 and intra-BWP frequency hopping} and intra-BWP frequency hopping . For example, if the sixth information indicates that the transmission mode is {mode 2 and intra-BWP frequency hopping}, the first signaling indicates {the location information of the first BWP and the first frequency offset information}. The terminal device determines the BWP resource according to the location information of the first BWP. The offset value of the frequency hopping within the BWP is determined according to the first frequency offset information. Information transmission is performed on BWP resources according to Mode 2, and frequency hopping is performed within the BWP. For example, if the sixth information indicates that the transmission mode is mode 3, the first signaling indicates the ID information of the second BWP. The terminal device determines the BWP resource according to the ID information of the second BWP. Information transmission is performed on the BWP resource according to Mode 3.

The terminal device determines the BWP resource according to the ID of the second BWP. Information transmission is performed on the BWP resource according to Mode 3.

For example, the sixth information indicates mode 1. The first signaling indicates the offset value used when the BWP hops out. The indication content of the first information may be the second offset value, or may be BWP ID information, or may be the location of the BWP. The specific method for determining resources according to the first signaling is as described above, and details are not repeated here.

For example, the sixth information indicates mode 2, or mode 2 without frequency hopping. The first information indicates location information of the first BWP. The indication content of the first signaling may be the location offset information of the BWP, may also be the BWP ID information, or may be the location information of the BWP. The specific method for determining the resource according to the first signaling is as described above, and details are not repeated here.

For example, the sixth information indicates mode 3, or mode 3 without frequency hopping. The first information indicates identification ID information of the BWP.

For example, the sixth information indicates mode 3 and frequency hopping within the BWP. The first information indicates ID information and first frequency offset information of the second BWP.

For example, the sixth information indicates no frequency hopping. The first signaling does not exist, or the first information field is used to indicate other information. For example, the other information is frequency domain resource allocation information.

For example, the sixth information indicates that the transmission mode is not frequency tuning. Then the first information can indicate at least one of frequency hopping offset and non-frequency hopping in the BWP. For example, K1 bit states or K1 indices of the first information correspond to intra-BWP frequency hopping offset values. For example, 1 bit state or 1 index of the first information corresponds to no frequency hopping. For example, the first information includes 2 bits, and the sixth information indicates that the transmission mode is not frequency tuning. The three bit states of the first information correspond to three frequency hopping offset values during frequency hopping in the BWP. One bit state of the first signaling corresponds to no frequency hopping.

For example, the sixth information indicates that the transmission mode is mode 1. Then, the first signaling can indicate at least one of frequency hopping offset and no frequency hopping outside the BWP. For example, K1 bit states or K1 indices of the first information correspond to BWP out-of-hop frequency offset values. For example, 1 bit state or 1 index of the first information corresponds to no frequency hopping. For example, the first information includes 2 bits, and the sixth information indicates that the transmission mode is not frequency tuning. The three bit states of the first information correspond to the three frequency hopping offset values when the frequency is hopping outside the BWP. One bit state of the first signaling corresponds to no frequency hopping.

In the embodiment of the present application, the sixth information indicates transmission mode information, and the first signaling indicates frequency domain resource switching information. The frequency domain resource switching information corresponding to different transmission modes may be the same or different. That is, the interpretation of the first signaling may be regarded as indicating the same offset parameter, or may correspond to different offset parameters. That is to say, in this application, when the sixth information indicates that the transmission mode is Mode 1, Mode 2, or Mode 3, the first signaling can use {second offset information, BWP location information, BWP ID} to correspond to these three types respectively. The first signaling can also use {BWP location information, BWP location information, BWP ID} to correspond to these three ways, and the first signaling can also use {BWP ID, BWP location information, BWP ID} to indicate these three ways respectively. The first signaling can also indicate these three ways through {BWP ID, BWP ID, BWP ID} respectively. The following describes each case separately.

Case 1: In different transmission modes, the second signaling indicates different offset parameters.

In a possible implementation manner, when the terminal device uses Mode 1 to transmit information, the corresponding offset information is the second offset information. The second offset information may be pre-configured by the network device. The second offset information is frequency hopping offset information, and when the terminal device applies the frequency hopping offset information, it needs to be tuned. The frequency hopping offset information is the number of frequency offset RBs between two hops. The frequency hopping offset information includes at most X1 candidate offset values, or at most X1 candidate offset RB numbers. Among them, X1 is a positive integer. For example, X1=4. For example, X1=2.

When the terminal device uses Mode 2 to transmit information, the corresponding offset information is BWP location information. The BWP location information may be pre-configured by the network device. The BWP position information is the starting position of the BWP after tuning. The BWP location information may include at most X2 candidate starting locations of the BWP, or at most X2 candidate starting RB sequence numbers of the BWP. Among them, X2 is a positive integer. For example, X2=4. For example, X2=2.

When the terminal device uses Mode 3 to transmit information, the corresponding offset information is the BWP ID. The BWP ID may be pre-configured by the network device. Network devices can configure up to X3 BWPs for end devices. Each BWP is configured with a corresponding BWP ID, BWP starting position, subcarrier spacing, bandwidth, and the like. The configuration parameters of different BWPs can be the same or different. Different BWPs are identified by different BWP IDs. When the terminal device applies the BWP corresponding to the new BWP ID, all RRC parameters of the BWP need to be updated. Among them, X3 is a positive integer. For example, X3=4. For example, X3=2.

Case 2: In different transmission modes, the second signaling indicates the same offset parameter.

In this implementation, it is assumed that all the second signaling indicates the BWP ID. At this time, the first signaling indicates that the transmission mode is mode 1, and the corresponding offset information is information corresponding to the BWP ID. The first signaling indicates that the transmission mode is mode 2, and the corresponding offset information is information corresponding to the BWP ID. The first signaling indicates that the transmission mode is the third transmission mode, and the corresponding offset information is information corresponding to the BWPID. The information corresponding to the BWP ID is the location information of the BWP corresponding to the BWP ID, or the location information of the BWP, or the default location information of the BWP, or the additional location information of the BWP.

However, the difference lies in that, when the terminal device uses Mode 1 to transmit information, the terminal device uses the BWP position corresponding to the BWP ID as the frequency offset. For example, the BWP starting RB sequence number corresponding to the BWP ID is 100, and the frequency offset of the fnth hop relative to the previous hop when the terminal equipment hops is 100 RB. where fn is a positive integer. fn can be configured by a network device.

When the terminal device uses Mode 2 to transmit information, the terminal device only updates the BWP location corresponding to the BWP ID. Other parameters corresponding to the BWP ID are not updated. Other parameters include at least one of subcarrier spacing, bandwidth, and DMRS bits.

When the terminal device uses Mode 3 to transmit information, the terminal device updates the BWP location corresponding to the BWP ID. At the same time, all parameters corresponding to the BWP ID are updated.

Case 3: In different transmission modes, some of the offset parameters indicated by the second signaling are the same, and some are different.

For example, the network device configures the second offset information and at least one BWP.

When the terminal device uses Mode 1 to transmit information, the corresponding offset information may be the second offset information. The second offset information may be pre-configured by the network device. The second offset information is frequency hopping offset information, and when the terminal device applies the frequency hopping offset information, it needs to tune. The frequency hopping offset information is the number of frequency offset RBs between two hops. The frequency hopping offset information includes at most X1 candidate offset values, or at most X1 candidate offset RB numbers. Among them, X1 is a positive integer. For example, X1=4. For example, X1=2.

When the terminal device uses Mode 2 to transmit information, the corresponding BWP location information may be information corresponding to the BWP ID. At this time, the terminal device may only update the BWP location corresponding to the BWP ID. Other parameters corresponding to BWP ID are not updated. Other parameters include at least one of subcarrier spacing, bandwidth, and DMRS bits. The network device can configure up to X3 BWPs for the terminal device. Among them, X3 is a positive integer. For example, X3=4. For example, X3=2.

When the terminal device uses Mode 3 to transmit information, the corresponding offset information may also be the BWP ID. At this time, the terminal device updates the BWP location corresponding to the BWP ID. At the same time, all parameters corresponding to the BWP ID are updated. For example, a network device can configure a maximum of X3 BWPs for an end device. When the terminal device applies the BWP corresponding to the new BWP ID, all RRC parameters of the BWP need to be updated. Among them, X3 is a positive integer. For example, X3=4. For example, X3=2.

For example, the network device is configured with at least one BWP, and each BWP is configured with at least one location.

When the terminal device uses Mode 1 to transmit information, the corresponding offset information may be information corresponding to the BWP ID. For example, the terminal device uses the BWP position corresponding to the BWP ID as the frequency offset. For example, the BWP starting RB sequence number corresponding to the BWP ID is 100, and the frequency offset of the fnth hop relative to the previous hop when the terminal equipment hops is 100 RB. where fn is a positive integer. fn can be configured by a network device.

When the terminal device uses Mode 2 to transmit information, the corresponding offset information is BWP location information. The BWP location information may be pre-configured by the network device. The BWP position information is the starting position of the BWP after tuning. The BWP location information may include at most X2 candidate starting locations of the BWP, or at most X2 candidate starting RB sequence numbers of the BWP. Among them, X2 is a positive integer. For example, X2=4. For example, X2=2.

When the terminal device uses Mode 3 to transmit information, the corresponding offset information is the BWP ID. The BWP ID may be pre-configured by the network device. Network devices can configure up to X3 BWPs for end devices. When the terminal device applies the BWP corresponding to the new BWP ID, it needs to update all the RRC parameters of the BWP. Among them, X3 is a positive integer. For example, X3=4. For example, X3=2.

For example, the network device is configured with at least one BWP, and each BWP is configured with at least one location.

When the terminal device uses Mode 1 to transmit information, the corresponding offset information may be BWP location information. For example, the terminal device applies BWP location information as frequency offset information. For example, the RB sequence number of the first additional location of the BWP is 100, and the frequency offset of the fnth hop relative to the previous hop when the terminal equipment hops is 100 RB. where fn is a positive integer.

When the terminal device uses Mode 2 to transmit information, the corresponding offset information is BWP location information. The BWP location information may be pre-configured by the network device. The BWP position information is the starting position of the BWP after tuning. The BWP location information may include at most X2 candidate starting locations of the BWP, or at most X2 candidate starting RB sequence numbers of the BWP. Among them, X2 is a positive integer. For example, X2=4. For example, X2=2.

When the terminal device uses Mode 3 to transmit information, the corresponding offset information is the BWP ID. The BWP ID may be pre-configured by the network device. Network devices can configure up to X3 BWPs for end devices. When the terminal device applies the BWP corresponding to the new BWP ID, it needs to update all the RRC parameters of the BWP. Among them, X3 is a positive integer. For example, X3=4. For example, X3=2.

In this application, the first signaling indicates the manner of information transmission, and the first signaling may also indicate frequency domain resource switching information. At this time, a joint indication can be implemented, that is, a joint indication of the mode to be transmitted and the frequency domain resource switching information corresponding to each transmission mode.

In a possible implementation manner, the first signaling can indicate at least one of the following: mode 1 and second frequency offset information; mode 2 and location information of the first BWP; mode 3 and ID information of the second BWP; Mode 2 and intra-BWP frequency hopping and {location information and first frequency offset information of the first BWP}; Mode 3 and intra-BWP frequency hopping and {ID information and first frequency offset information of the second BWP}; BWP Internal frequency hopping and first frequency offset information; no frequency hopping; no tuning.

For example, the network device configuration parameters include: N BWP start positions, M BWP IDs, X first frequency hopping offset values (FH offsets) for frequency hopping within BWP, and Y for frequency hopping outside BWP The second frequency hopping offset. For example, the first signaling indicates that Y second frequency hopping offsets in mode 1 require Y bit states. The first signaling indicates that the N BWP starting positions of Mode 2 require N states or (N-1) bit states. Among them, N is the number of BWP locations configured by the base station, and (N-1) is the number of BWP locations that can be changed (new). The first signaling indicates that the BWP ID information of Mode 3 requires (M-1) states or M bit states. Among them, M is the number of BWP IDs configured by the base station, and (M-1) is the number of changeable (new) BWP IDs. As mentioned above, in this application, the terminal device can also support mode 2 and frequency hopping, and the indication of the first signaling requires X*N bit states or X*(N-1) bit states. In this application, the terminal device may also support mode 3 and frequency hopping at the same time, and the indication of the first signaling requires X*(M-1) bit states or X*M bit states. The first signaling indicates that no frequency hopping requires 1 bit state. For example, N=3, X=4, M=4, Y=2. Therefore, as shown in Table 1, 5 bits can be used to indicate various transmission modes indicated by the first signaling in the embodiment of the present application and their corresponding frequency domain resource switching parameters.

Table 1. Different status bits indicate different meanings

It should be noted that each status bit in Table 1 and its corresponding indication content are only illustrative and not limited.

For example, the parameters configured by the network device include: N BWP starting positions, M BWP IDs, and X first frequency hopping offset values (FH offset) for frequency hopping within the BWP. For example, the first signaling indicates that N BWP starting positions of Mode 2 require N states or (N-1) bit states. The first signaling indicates that the BWP ID of Mode 3 requires (M-1) states or M bit states. When the terminal device uses Mode 1 for information transmission, the corresponding offset information may be BWP location information. Then, the first signaling indicates that the frequency hopping offset outside the N BWPs in mode 1 requires N bit states. As mentioned above, the terminal device in this application may also support mode 2 and frequency hopping, and the indication of the first signaling requires X*N bit states or X*(N-1) bit states. In this application, the terminal device can also support mode 3 and frequency hopping at the same time, and the indication of the first signaling requires X*(M-1) bit states or X*M bit states. The first signaling indicates that no frequency hopping requires 1 bit state. As mentioned above, the terminal device in this application may also support mode 2 and frequency hopping, and the indication of the first signaling requires X*N bit states or X*(N-1) bit states. In this application, the terminal device can also support mode 3 and frequency hopping at the same time, and the indication of the first signaling requires X*(M-1) bit states or X*M bit states. The first signaling indicates that no frequency hopping requires 1 bit status. For example, assuming N=2, X=4, M=4, a total of 2+2+3+4*3+4*2+1=28 is required. Therefore, as shown in Table 2, 5 bits may be used to indicate various transmission modes indicated by the first signaling in the embodiment of the present application and their corresponding offset parameters. Among them, the transmission mode corresponding to the state "11110" and the state "11111" is mode 1, and the frequency hopping offset is determined by the BWP position.

Table 2. Different status bits indicate different meanings

It should be noted that, the status bits in Table 2 and their corresponding indication contents are only illustrative and not limited.

For example, the network device configuration parameters include: M BWP IDs, X first frequency hopping offsets (FH offsets) for frequency hopping within the BWP, and Y second frequency hopping offsets for frequency hopping outside the BWP. For example, the first signaling indicates that Y second frequency hopping offsets in Mode 1 require Y bit states. The first signaling indicates that the BWP ID of mode 3 requires (M-1) states or M bit states. When the terminal device uses Mode 2 to transmit information, the corresponding BWP location may be the information corresponding to the BWP ID. Then the first signaling indicates that the M BWP positions of Mode 2 require M bit states. As mentioned above, the terminal device in this application may also support mode 2 and frequency hopping, and the indication of the first signaling requires X*M bit states or X*(M-1) bit states. In this application, the terminal device can also support mode 3 and frequency hopping at the same time, and the indication of the first signaling requires X*(M-1) bit states or X*M bit states. The first signaling indicates that no frequency hopping requires 1 bit state. For example, assuming X=4, M=4, Y=2, a total of 2+3+3+4*3+4*3=32 is required. Therefore, as shown in Table 3, 5 bits may be used to indicate various transmission modes and corresponding offset parameters indicated by the first signaling in the embodiment of the present application. Among them, the transmission mode corresponding to the state "00010" is mode 2, and the BWP position is determined according to the position corresponding to the BWP ID.

Table 3. Different status bits indicate different meanings

It should be noted that, each status bit in Table 3 and its corresponding indication content are only illustrative and not limited.

According to the communication method provided by the embodiment of the present application, the network device can flexibly indicate in multiple transmission change modes, so as to obtain frequency domain diversity gain and network load balance. Further, according to the indication method designed in this application, signaling overhead can be saved.

FIG. 4 is a schematic block diagram of the communication method 400 of the present application, and the method shown in FIG. 4 includes S401 to S403. Each step is described in detail below.

For example, the number of BWP IDs configured on the network device is N1. The number of candidate positions in Mode 1 is N2. The number of candidate positions in Mode 2 is N3. The number of offset values for frequency hopping in the BWP is N4. Among them, N1, N2, N3 and N4 are all integers greater than 0.

Step S401, the terminal device acquires frequency hopping identification information.

For example, the frequency hopping identification information may be indicated in the DCI. The frequency hopping identification information may be a field in the DCI. For example, the frequency hopping identification information may be indicated in RRC signaling. The frequency hopping identification information may be a field in the RRC signaling. The frequency hopping identification information indicates whether frequency hopping is enabled. For example, enable; disable/disable.

For example, the frequency hopping identification information may be 1 bit or 2 bits. The signaling design is described below for these two cases respectively.

Case 1: The frequency hopping identification information is 1 bit. For example, a bit status of "1" may indicate that the terminal equipment performs frequency hopping transmission, and a bit status of "0" may indicate that the terminal equipment does not perform frequency hopping transmission. When the frequency hopping identification information indicates that frequency hopping is enabled, it may indicate to enable at least one of intra-BWP frequency hopping, inter-BWP frequency hopping (or outside BWP frequency hopping), intra-slot frequency hopping or inter-slot frequency hopping.

Step S402, the network device sends the first signaling to the terminal device.

Step S403, the terminal device receives the first signaling within the frequency range of the first BWP, and determines the transmission mode information.

Further, the terminal device may communicate according to the indication of the first signaling.

It should be noted that the above steps may be performed separately or together. That is, the frequency hopping identification information and the manner of transmitting the information may be in one message, such as DCI, or may be in different messages.

The terminal device may receive the first signaling within the frequency range of the first BWP, determine the transmission mode, and communicate according to the determined transmission mode.

In a possible implementation manner, when the frequency hopping identification information indicates that frequency hopping is not enabled:

For example, the first signaling can indicate at least one of the following: {location information of the first BWP}; {ID information of the second BWP}; no frequency hopping. For example, when the first signaling indicates the location information of the first BWP, the BWP resource is determined according to the location information of the first BWP. Information transmission is performed on the BWP resource according to Mode 2. For example, when the first signaling indicates the ID information of the second BWP, the BWP resource is determined according to the ID information of the second BWP. The information is transmitted according to Mode 3 on the BWP resource. For example, the first signaling indicates no frequency hopping, and the terminal device performs information transmission in the first BWP.

In a possible implementation manner, when the frequency hopping identification information indicates that frequency hopping is enabled:

The first signaling can indicate at least one of the following: {location information of the first BWP}; {ID information of the second BWP}; {location information and first frequency offset information of the first BWP}; {the location information of the second BWP} ID information and first frequency offset information}; second frequency offset information. The terminal device determines the resource switching position according to the first signaling, and performs information transmission. The information transmission mode may be indicated by the sixth information, or may be indicated by the first signaling. As described in the previous example, it will not be repeated here.

Example 1, the network device pre-configures information corresponding to each transmission mode. For example, BWP ID list information, BWP location information, first offset information, and second offset information are configured.

For example, N2 candidate positions of Mode 1 are determined according to the second offset information. For example, N3 candidate positions in mode 2 are determined according to the position information of the BWP. For example, N4 offset values for frequency hopping within the BWP are determined according to the first offset information. For example, (N1-1) second BWPs, or N1 second BWPs, are determined according to the BWP ID list information. For example, the number of BWPIDs configured by the network device is N1, and the number of second BWP IDs is (N1-1). Because if the indicated BWP ID is the same as the currently used BWP ID, it is considered that it is not the second BWP (new BWP), and no BWP switching is required.

For example, when the frequency hopping identification information does not enable frequency hopping, the states that can be indicated by the first signaling include at least one of the following: N1 pieces of BWP ID information, N3 pieces of BWP location information, and at least one reserved state. Alternatively, the states that can be indicated by the first signaling include at least one of the following: (N1-1) pieces of BWP ID information, N3 pieces of BWP location information, and at least one reserved state. Alternatively, the states that can be indicated by the first signaling include at least one of the following: N1 pieces of BWP ID information, N3-1) pieces of BWP location information, and at least one reserved state.

For example, when the indication state of the first signaling corresponds to one of N1 or (N1-1) pieces of BWP ID information, the terminal device determines the BWP resource according to the ID information of the BWP indicated by the first signaling. The information is transmitted according to Mode 3 on the BWP resource.

For example, when the indication state of the first signaling corresponds to one of N3 or (N3-1) pieces of BWP location information, the terminal device determines the BWP resource according to the BWP location information indicated by the first signaling. Information is transmitted on the BWP resource according to Mode 2.

For example, when the frequency hopping identification information indicates that frequency hopping is enabled, the states that can be indicated by the first signaling include at least one of the following: a combination of M1 BWP ID information and the first offset information, M2 BWP location information and the first offset information The combination of shift information, M3 pieces of second offset value information for frequency hopping outside the BWP, and M4 pieces of first offset information for frequency hopping within the BWP. M1, M2, M3, and M4 are all integers greater than 0. Wherein, M1=(N1-1)*N4 or M1=N1*N4. M2=N2*N4 or M2=(N2-1)*N4. M3=N2. M3=N4. For example, N1=4. For example, N2=4. For example, N3=4. For example, N4=4.

For example, when the indication state of the first signaling corresponds to one of the M1 first-type states, the terminal device determines the BWP resource according to the ID information of the BWP indicated by the first signaling. The terminal device determines the offset value of frequency hopping within the BWP according to the first frequency offset information. Information transmission is performed on BWP resources according to mode 3, and frequency hopping is performed within the BWP. For example, the first type of state is a combination of BWP ID information and first offset information.

For example, when the indication state of the first signaling corresponds to one of M2 second type states, the terminal device determines the BWP resource according to the BWP location information indicated by the first signaling. The terminal device determines the offset value of frequency hopping within the BWP according to the first frequency offset information. Information transmission is performed on BWP resources according to Mode 2, and frequency hopping is performed within the BWP. For example, the second type of state is a combination of BWP location information and first offset information.

For example, when the indication state of the first signaling corresponds to one of the M3 BWP outer frequency hopping offset information states, the terminal device performs frequency hopping transmission on the frequency domain resource determined according to the offset information.

For example, when the indication state of the first signaling corresponds to one of the M4 intra-BWP frequency hopping offset information states, the terminal device performs frequency hopping transmission on the frequency domain resource determined according to the offset information.

Specifically, for example, when the frequency hopping identification information indicates that frequency hopping is not enabled, the first signaling requires 3 bits. Wherein, N1-1=3 states are required to indicate the new BWP ID. N3=4 states indicate the BWP position. 1 state is reserved state.

Specifically, for example, when the frequency hopping identification information indicates that frequency hopping is enabled, the first signaling requires 5 bits. Wherein, M3=N2=4 states indicate frequency hopping to the second offset information outside the BWP. M1=(N1-1)*N4=3*4=12 states indicate a combination of BWPID information and first offset information. M2=N2*N4=4*4=16 states indicate a combination of BWP location information and first offset information. The first signaling may indicate 4+12+16=32 states, including various combinations of frequency hopping transmission. The BWP location information includes the current BWP location and the changed BWP location, so the BWP location information is frequency hopping within the BWP, including the case where the BWP location remains unchanged and the frequency is hopping within the BWP.

For example, when the frequency hopping identifier indicates that frequency hopping is not enabled, the first signaling may occupy 3 bits a1, a2, and a3, and the frequency domain resource allocation field occupies A bits. When the frequency hopping identifier indicates that frequency hopping is enabled, the first signaling may occupy 5 bits, and the frequency domain resource allocation field occupies (A-2) bits. The 5 bits occupied by the first information include a1, a2, and a3, and may also include the 2 most significant bits (most significant bits, MSBs) in the frequency domain resource allocation field. In this way, it can be ensured that regardless of the value of the frequency hopping identifier indication, the total number of bits included in the control information where the first signaling is located remains unchanged. In addition, when frequency hopping is not used, it is not necessary to occupy the bits of frequency domain resource allocation resources, which ensures the flexibility of frequency domain resource allocation. During frequency hopping, the frequency resource allocation field is occupied. Although it has a certain impact on the flexibility of frequency domain resource allocation, it can obtain a wider range of resource scheduling flexibility.

Example 2, if the network device is configured with BWP ID information corresponding to BWP handover, configured with BWP location information used for BWP location change, and configured with first offset information used for intra-BWP frequency hopping. And the second offset information of the frequency hopping outside the BWP is obtained through the BWP location information. That is, the terminal device applies the BWP location information as the frequency offset information for frequency hopping outside the BWP. Then in this example, N2=N3.

Example 3, if the network device is configured with BWP ID information corresponding to BWP handover, the first offset information used for intra-BWP frequency hopping is configured. The second offset information of the frequency hopping outside the BWP is obtained through information corresponding to the BWP ID information. The BWP location information is obtained through the information corresponding to the BWP ID. Then in this example, N2=N1, N3=N1.

Similarly, in Example 4, if the network device is configured with BWP ID information corresponding to BWP handover, configured with BWP location information used for BWP location change, and configured with first offset information used for intra-BWP frequency hopping. The second offset information of the frequency hopping outside the BWP is obtained through the BWP ID information. Then in this example, N2=N1.

Case 2: When the frequency hopping identification information is multiple bits, the frequency hopping identification can indicate at least one of the following: BWP handover and frequency hopping within BWP, mode 2 and frequency hopping within BWP, BWP handover and no frequency hopping within BWP, mode 2 and no frequency hopping within the BWP, frequency hopping outside the BWP, frequency hopping within the BWP, and no frequency hopping.

For example, the states that can be indicated by the first signaling include at least one of the following: M1 combinations of BWP ID information and first offset information, M2 combinations of BWP location information and first offset information, and M3 combinations of BWP ID information and first offset information. The second offset value information of frequency hopping, M4 pieces of first offset information for intra-BWP frequency hopping, M5 pieces of information for non-frequency hopping, N1 pieces of BWP ID information, and N3 pieces of BWP location information. M1, M2, M3, and M4 are all integers greater than 0. For example, M1=(N1-1)*N4 or M1=N1*N4. M2=N2*N4 or M2=(N2-1)*N4. M3=N2. M3=N4. M5=N1+N3 or M5=N1+N3-1. For example, assume N1=4. N2=4. N3=4. N4=4.

For example, the frequency hopping identification information may include 2 bits. Table 4 shows the contents of the 4-bit state indication corresponding to 2 bits.

Table 4. Different Status Bits Indicate Different Content

bit status Instruction content 00 BWP handover and frequency hopping within BWP 01 Mode 2 and frequency hopping within BWP 10 Mode 1 (or frequency hopping outside BWP) 11 no frequency hopping

For example, the frequency hopping identification information includes 3 bits. The contents of the 8-bit state indication corresponding to 3 bits are shown in Table 5.

It should be noted that, the status bits in Table 4 and Table 5 and their corresponding indication contents are only illustrative and not limited.

Example 1, the network device configures information corresponding to each transmission mode. For example, {BWP ID information and first offset information} corresponding to {BWP handover and intra-BWP frequency hopping} are configured, and {BWP location information and first offset information} corresponding to {mode 2 and intra-BWP frequency hopping} are configured }, second offset information for frequency hopping outside the BWP is configured.

For example, the frequency hopping identification information includes 2 bits, which can indicate: BWP handover and frequency hopping within BWP, mode 2 and frequency hopping within BWP, frequency hopping outside BWP, and no frequency hopping.

For example, N1=4, N3=4, N2=4. N4=4. The network device is configured with 4 BWPs, each BWP is configured with 4 BWP positions, and 4 BWP external frequency hopping offsets are configured. Four intra-BWP frequency hopping offsets are configured. Then M1=12, M2=16, M3=4, M4=7. The first signaling uses 6 bits to indicate 39 states.

According to the communication method provided by the embodiment of the present application, the terminal device can obtain the frequency hopping identification information, the network device can flexibly instruct the information transmission mode of the terminal device according to the service requirements of the terminal device, and can obtain the frequency domain diversity gain and load balance, ensuring that Information transmission reliability.

Fig. 5 is a schematic block diagram of a communication method 500 of the present application, and the method shown in Fig. 5 includes S501 to S503. Each step is described in detail below.

Step S501, the terminal device acquires frequency hopping identification information.

As mentioned above, in this application, the frequency hopping identification information may be indicated in the DCI. The frequency hopping identification information can also be indicated in RRC signaling. The frequency hopping identification information may be a field in the DCI. The frequency hopping identification information may be a field in the RRC signaling. The frequency hopping identification information indicates whether frequency hopping is enabled. For example, enable; disable/disable. For example, the frequency hopping identification information may be 1 bit.

When the frequency hopping identification information indicates that frequency hopping transmission is enabled, in step S502, the network device sends first information to the terminal equipment, where the first information indicates the frequency hopping transmission mode of the terminal equipment.

The frequency hopping transmission manner in this application includes a first frequency hopping transmission manner and a second frequency hopping transmission manner. For example, the first frequency hopping mode is intra-BWP frequency hopping, and the second frequency hopping mode is inter-BWP frequency hopping (or external BWP frequency hopping). For example, the first frequency hopping mode is intra-slot frequency hopping, and the second frequency hopping mode is inter-slot frequency hopping. For example, the first frequency hopping method is intra-slot frequency hopping and intra-BWP frequency hopping, and the second frequency hopping method is inter-slot frequency hopping and inter-BWP frequency hopping (or outside BWP frequency hopping).

Step S503, the network device sends second information to the terminal device, where the second information indicates frequency offset information of frequency hopping transmission.

For example, the first frequency hopping mode is BWP internal frequency hopping, and the second frequency hopping mode is BWP external frequency hopping. The first information indicates that when the terminal equipment transmits in the first frequency hopping manner, the second information indicates the first frequency offset information. When the first information indicates that the terminal device transmits in the second frequency hopping manner, the second information indicates second frequency offset information.

For example, the first frequency hopping manner is intra-slot frequency hopping, and the second frequency hopping manner is inter-slot frequency hopping. The first information indicates that when the terminal equipment transmits in the first frequency hopping manner, the second information indicates the offset information of the frequency hopping in the time slot. The first information indicates that when the terminal equipment transmits in the second frequency hopping mode, the second information indicates offset information of frequency hopping between time slots.

For example, the first frequency hopping manner is intra-slot frequency hopping and BWP intra-BWP frequency hopping, and the second frequency hopping manner is inter-time slot and frequency hopping frequency hopping outside the BWP. The first information indicates that when the terminal device transmits in the first frequency hopping manner, the second information indicates the offset information of frequency hopping within the time slot and frequency hopping within the BWP. The first information indicates that when the terminal equipment transmits in the second frequency hopping mode, the second information indicates the offset information of frequency hopping outside the BWP between time slot frequency hopping.

Step S504, the terminal device receives the second information, and communicates according to the first information and the instructions of the second information.

The terminal device may receive the first information and the second information within the frequency range of the first BWP, determine the transmission mode, and perform communication according to the determined transmission mode.

It should be noted that the above steps may be performed separately or together. For example, the frequency hopping identification information and/or the first information and/or the second information may be transmitted in the same DCI, or may be transmitted in different DCIs.

FIG. 6 is a schematic block diagram of a communication method 600 of the present application, and the method shown in FIG. 6 includes S601 to S603. Each step is described in detail below.

Step S601, the terminal device acquires type information.

In this application, the type may be the method used for information transmission, or the change type of the BWP location, or the processing time indicating the location change of the BWP, or the number of changes in the related parameters of the BWP, or the type of BWP configuration information. The following are respectively explained:

Type can be the way in which the information is transmitted. For example, the first type is Mode 2 of information transmission. The second type is the way information is transmitted3.

The type may be a change type of BWP location. For example, the first type is BWP tuning, and/or frequency tuning, and/or only changing BWP position, and/or unchanged BWP ID. The second type is BWP handover, and/or BWP ID change.

The type can be the processing time required to change the position of the BWP. For example, if the type is the first type, when the terminal equipment information is transmitted, the time duration required for the frequency resource switching is T1. For example, if the type is the second type, the duration T2 required for frequency resource switching when terminal equipment information is transmitted. For example, T1<T2. For example, T1=T2.

The type can be the relevant parameter change amount of the BWP. For example, the first type only changes related parameters of N BWPs including BWP ID and BWP location, and the second type is to change related parameters of M BWPs including BWP ID and BWP location. where N and M are both positive integers. N is less than M. For example, N equals 2. For example, M is equal to 20.

The type can be a BWP configuration information type. The first type only changes the BWP ID and BWP location. For example, when the type is the first type, in the RRC parameters related to the BWP ID, at least other parameters except the first characteristic parameter are not updated. The first characteristic parameter includes one or more of parameters of BWP ID parameter, BWP location information and BWP size. The second type is to change not only the BWP ID and BWP location, but also the BWP width, subcarrier spacing, DMRS location, time domain resource allocation, power control information, and the like. For example, when the type is the second type, all RRC parameters related to the BWP ID are updated.

In this application, the type may be indicated in the DCI. Type information can be a field in the DCI. For example, the terminal device can obtain the type information according to the indication in the DCI. Type information can also be indicated in RRC signaling. Type information may be a field in RRC signaling. For example, the terminal device can obtain the type information according to the indication in the RRC.

Step S602, the network device sends third information to the terminal device, where the third information indicates the location information of the BWP or the ID information of the BWP.

Step S603, the terminal device receives the type information and the third information within the frequency range of the first BWP, and determines the BWP resource. The type information and the third information may be transmitted in the same signaling, or may be transmitted in different signaling. For example, the type information and the third information are different fields or different bits in the same piece of DCI.

Further, the terminal device can communicate on the determined BWP resource.

For example, if the type information indicates the first type and the third information indicates the location information of the first BWP, the terminal device determines the BWP resource according to the location information of the first BWP. The information is transmitted according to Mode 2 on the BWP resource.

For example, if the type information indicates the second type and the third information indicates the ID information of the second BWP, the terminal device determines the second BWP resource according to the ID information of the second BWP, and the terminal device applies All parameter configurations corresponding to the second BWP ID. Information transmission is performed on the BWP resource according to Mode 3.

It should be noted that the above steps may be performed separately or together. For example, the type information and the third information may be transmitted in the same DCI, or may be transmitted in different DCIs.

For example, when the terminal device determines the first BWP resource according to the first type, the terminal device only applies the location of the first BWP. For example, when the terminal device determines the second BWP resource according to the second type, the terminal device applies all parameter configurations corresponding to the second BWP.

FIG. 7 is a schematic block diagram of a communication method 700 of the present application, and the method shown in FIG. 7 includes S701 to S703. Each step is described in detail below.

Step S701, the terminal device acquires type information.

In this step, the type information obtained by the terminal device and the manner thereof may be similar to step S601 of the method 600, and will not be repeated.

Step S702, the network device sends fourth information to the terminal device, where the fourth information indicates the ID information of the BWP.

For example, the ID information of the BWP may include the ID information of the first BWP and/or the ID information of the second BWP.

Step S703, the terminal device receives the type information and the fourth information in the frequency range of the first BWP, and determines the BWP resource.

In a possible implementation manner, for example, if the type information indicates the first type, the terminal device determines the resources of the BWP according to the ID information of the BWP and the location information of the BWP. The location information of the BWP is the default location of the BWP. If the type information indicates the second type, the terminal device determines the second BWP resource according to the ID information of the BWP, and the terminal device applies all associated parameter configurations.

For example, if the type information indicates the first type, the terminal device only applies the location of the BWP corresponding to the second BWP ID. No other parameters related to this BWP apply. If the type information indicates the second type, the terminal device applies all parameter configurations associated with the new BWPID.

In another possible implementation manner, when the type information indicates the first type, the terminal device needs the first processing duration; when the type information indicates the second type, the terminal device needs the second processing duration; wherein the first processing duration Less than or equal to the second processing duration.

It should be noted that the processing duration in this application is the duration between the first time and the second time. The first time is the time when the terminal device receives the fourth indication information, or the time when the fourth indication information ends, or the time when the last symbol of the fourth indication information ends. The second time is when the terminal device applies the new BWP, or when the terminal device can send and/or receive information on the new BWP resource, or when the terminal device completes frequency tuning. The first processing duration includes frequency tuning time, and/or signaling analysis time. The second processing duration includes frequency tuning time, and/or signaling analysis time, and/or BWP-related parameter update time, and/or BWP-related parameter loading and application time. For example, the first processing duration is shorter than the second processing duration. For example, the first processing duration is equal to the second processing duration. The first processing duration and the second processing duration are the time difference between the time when the terminal device receives the downlink control information and the time when the new BWP resource is applied.

After the terminal device determines the BWP resource, it can communicate on the BWP.

Fig. 8 is a schematic block diagram of a communication method 800 of the present application, and the method shown in Fig. 8 includes S801 to S802. Each step is described in detail below.

Step S801, the network device sends fifth information to the terminal device, where the fifth information indicates BWP ID information.

Step S802, the terminal device receives the fifth information within the frequency range of the first BWP, and determines the BWP resource.

In a possible implementation manner, the fifth information can indicate N pieces of BWP ID information, and when the fifth information is that the BWP ID information indicated by the terminal device belongs to the N BWP IDs, the terminal device only applies the indicated BWP ID information and the default location of the BWP, where N is a positive integer.

In a possible implementation manner, the fifth information can indicate M pieces of BWP ID information, and when the fifth information is that the BWP ID information indicated by the terminal device belongs to M pieces of BWP ID information, the terminal device applies all BWP ID information associated with the indicated BWP ID. Parameter configuration, where M is a positive integer.

For example, the network device is configured with N first-type BWPs, and the configuration of each BWP only includes corresponding BWP ID information and BWP location information. Among them, N is a positive integer. The network device is configured with M BWPs of the second type, and the configuration information of each BWP in the M BWPs includes at least one of ID information, location information, bandwidth information, subcarrier spacing, control channel resource set, data channel configuration, and DMRS configuration. kind. Among them, M is a positive integer.

其中，

为上取整运算。例如， K1个比特状态中前N个比特状态或前N个索引对应N个第一类型BWP ID信息。K1个 比特状态中后M个比特状态或前M个索引对应M个第二类型BWP ID信息。For example, the fifth information can be used to indicate ID information of (N+M) BWPs. For example, the fifth information may indicate K1 bit states, where K1=log2(N+M) or

in,

It is a round-up operation. For example, the first N bit states or the first N indices in the K1 bit states correspond to N pieces of BWP ID information of the first type. Among the K1 bit states, the last M bit states or the first M indices correspond to M pieces of BWP ID information of the second type.

For another example, the fifth information includes 1 bit to indicate whether to select from N BWPs or M BWPs, and the fifth information includes K2 bits to indicate corresponding BWP ID information. in,

For example, N equals M. For example, N=4, M=4. For example, the fifth information includes 3 bits, indicating 8 states, and each state corresponds to BWP ID information of one BWP among N+M=8 BWPs. For example, the status of bits 0 to 3 of the fifth information are respectively used to indicate four BWPs that only include the BWP ID and the location of the BWP. For example, the 4-7 bit states of the fifth information are respectively used to indicate 4 BWPs including all relevant configurations of the BWP.

Because, the terminal device first determines whether the BWP type is the first type BWP or the second type BWP, and then determines the BWP ID information according to the indication of the fifth information. N values required

In the embodiment of the present application, N=M, and the number of bits required for the fifth information is the same, which can avoid the situation that the number of bits is different in different situations, resulting in different DCIs. Or because the number of bits occupied by the DCI is adjusted in different situations, zero-padding is performed on a field with a small number of bits, which leads to a waste of resources.

After the terminal device determines the BWP resource, it can communicate on the BWP.
