Description

Technical Field

[0001] This application relates to, but is not limited to, the field of communications, and particularly to a frequency domain resource allocation method, a first terminal, a computer-readable storage medium, and a computer program product. Background Technology

[0002] Currently, in subband non-overlapping full duplex (SBFD) systems, the bandwidth available for uplink / downlink transmission differs between SBFD time slots / symbols and non-SBFD time slots / symbols. Figure 1 As shown, slots #0 and #4 are non-SBFD slots / symbols, while slots #1, #2, and #3 are SBFD slots / symbols. Assuming the carrier bandwidth is 100MHz, then the bandwidth available for uplink transmission in slot #4 is 100MHz, and the bandwidth available for downlink transmission in slot #0 is 100MHz. Assuming the bandwidth of the uplink subband (UL subband) configured on the SBFD slots is 20MHz, and the bandwidth of the downlink subband (DL subband) configured on the SBFD slots is 80MHz, then the bandwidth available for uplink transmission in slots #1, #2, and #3 is the middle 20MHz.

[0003] Since the bandwidth available for uplink / downlink transmission differs between SBFD symbols and non-SBFD symbols, the frequency domain resource allocation method employed in related technologies may result in overlapping allocated resources with unavailable resources. Summary of the Invention

[0004] This application provides a frequency domain resource allocation method, a first terminal, a computer-readable storage medium, and a computer program product, such that during multi-slot transmission, the frequency domain resources allocated in the SBFD symbol fall within the range of available frequency domain resources.

[0005] Firstly, a frequency domain resource allocation method is provided, applied to a first terminal, including:

[0006] Receive downlink control information sent by a first device; wherein the downlink control information is used to schedule a physical uplink shared channel;

[0007] Obtain the physical uplink shared channel frequency domain indication information;

[0008] Based on the time-domain resources occupied by the physical uplink shared channel and the frequency-domain indication information, the frequency-domain resource location of the physical uplink shared channel is determined.

[0009] Secondly, a first terminal is provided, the first terminal comprising:

[0010] A receiving module is configured to receive downlink control information sent by a first device; wherein the downlink control information is used to schedule a physical uplink shared channel;

[0012] The processing module is used to determine the frequency domain resource location of the physical uplink shared channel based on the time domain resources occupied by the physical uplink shared channel and the frequency domain indication information.

[0013] Thirdly, a first terminal, the first terminal comprising:

[0014] Memory, used to store executable instructions;

[0015] The processor, when executing executable instructions stored in the memory, implements the frequency domain resource allocation method described above.

[0017] Fifthly, embodiments of this application provide a computer program product, including a computer program, which, when executed by a processor, implements the frequency domain resource allocation method described above.

[0018] Through the above technical solution, when uplink transmission spans SBFD symbols and non-SBFD symbols, the terminal determines the location of frequency domain resources in SBFD symbols and non-SBFD symbols, so that the allocated frequency domain resources fall within the range of usable frequency domain resources, thus ensuring UE transmission performance.

[0040] To facilitate understanding of the technical solutions of the embodiments of this application, the relevant technologies of the embodiments of this application are described below. The following relevant technologies are optional solutions and can be combined with the technical solutions of the embodiments of this application in any way, and they all fall within the protection scope of the embodiments of this application.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0042] Before explaining this application, the frequency domain resource allocation scheme in the related art is described below:

[0043] In a Time Division Duplex (TDD) system, on a single symbol within a carrier, both the base station and the terminal can only perform uplink or downlink transmission, not both simultaneously. As a result, the uplink / downlink transmission conversion delay in a TDD system is relatively large, and the uplink capacity and coverage are limited. To reduce the transmission delay and improve uplink coverage and capacity in a TDD system, SBFD technology divides the carrier bandwidth into several subbands that occupy different frequency resources, allowing the base station to perform uplink and downlink transmissions simultaneously on a single symbol.

[0044] NR supports two frequency domain resource allocation types: Resource Allocation (RA) Type 0 and RA Type 1. RA Type 0 is a resource allocation mechanism based on Resource Block Groups (RBGs). Specifically, it uses the starting frequency domain position of the Bandwidth Part (BWP) as the starting point and divides all PRBs in the BWP into N groups with RBG granularity. RBG In DCI, the FDRA field carries an RBG of length N. RBG The bitmap represents the network's allocation mechanism. Each bit corresponds to an RBG (Resource Block Group). A bit value of 1 indicates that the corresponding RBG has been allocated to the User Equipment (UE). Through RA Type 0, the network can allocate non-contiguous frequency domain resources to the terminal. RA Type 1 is a resource allocation mechanism based on Resource Indicator Value (RIV), used to allocate a set of contiguous Virtual Resource Blocks (VRBs) to the terminal. Specifically, the FDRA field in the DCI carries a Resource Indicator Value (RIV), and the starting VRB and the number of RBs can be calculated from the RIV.

[0045] It should be noted that, with Figure 1Taking the SBFD symbols and non-SBFD symbols available for uplink / downlink transmission as an example, when the base station schedules / configures the terminal to perform uplink transmissions on multiple time slots, such as PUSCH repetition, TBoMS, configured grant, etc., the PUSCH transmission may span SBFD symbols and non-SBFD symbols. In this case, if the frequency domain resource allocation method in related technologies is used, multiple repetitions / transmissions will be allocated the same frequency domain resource location, which may lead to the overlap of frequency domain resources allocated on SBFD symbols with unavailable resources, such as... Figure 3 As shown, in the SBFD symbol, the frequency domain resource (PUSCH Rep#0) corresponding to PUSCH falls in the DL subband of Slot#3, and PUSCH transmission cannot be performed normally.

[0046] Figure 4 This is a flowchart illustrating a frequency domain resource allocation method provided in an embodiment of this application, as shown below. Figure 4 As shown, this method is applied to Figure 2 The terminal device 110 in the wireless communication system 100 shown includes the following method:

[0047] Step 401: Receive downlink control information sent by the first device.

[0048] Downlink control information is used to schedule the physical uplink shared channel.

[0049] In this embodiment of the application, the first terminal, namely Figure 2 Terminal device 110 in the middle receives the first device, that is Figure 2 The first message sent by network device 120 in the middle; wherein the first message includes DCI.

[0050] In some embodiments, the DCI includes scheduling information for the data channel, which may include transmission parameters for the data channel. Based on these transmission parameters, network devices and terminal devices transmit data through the data channel.

[0051] In some embodiments, the first message may be a radio resource control (RRC) message, a broadcast message, a system message, or a medium access control (MAC) control element (CE) message.

[0052] Step 402: Obtain the physical uplink shared channel frequency domain indication information.

[0053] In some embodiments, the frequency domain indication information includes first information and second information;

[0054] The first information is used to indicate the resource allocation of the physical uplink shared channel of the reference first frequency domain resource, or the RB index; the second information is used to indicate the frequency domain resource interval index allocated on the second time domain resource; here, the frequency domain resource allocation is the size of the reference first frequency domain resource, and the frequency domain resource allocation interval is the bandwidth size of the reference first frequency domain resource and the second frequency domain resource.

[0055] Here, the first frequency domain resource includes the UL frequency domain resource of the first time domain resource, such as the UL usable PRB or SBFD uplink subband, and the size of the first frequency domain resource is X1. The first time domain resource includes time domain resources configured as downlink or flexible symbols in the time division duplex cycle, that is, time domain resources configured as DL slots / symbols and / or flexible slots / symbols in the TDD cycle, and configured with uplink resources (SBFD uplink subband), which are SBFD symbols.

[0056] Here, the second frequency domain resource includes the UL frequency domain resource of the second time domain resource, such as UL BWP, and the size of the second frequency domain resource is X2. The second time domain resource includes time domain resources configured as uplink symbols in the time division duplex cycle and configured as UL slots / symbols in the TDD cycle, that is, non-SBFD symbols.

[0057] It should be noted that the network side determines the bit length of the physical shared channel frequency domain indication information based on the bandwidth of the second frequency domain resources, such as the bit size of the frequency domain resource allocation field in DCI.

[0058] In some embodiments, the second frequency domain resource includes M frequency domain resource intervals; wherein M is a positive integer, that is, M bits of second information are used to indicate the M frequency domain resource intervals divided by the second frequency domain resource.

[0059] Step 403: Based on the time-domain resources and frequency-domain indication information occupied by the physical uplink shared channel, determine the frequency-domain resource location of the physical uplink shared channel.

[0060] This application discloses a frequency domain resource allocation method applied to a first terminal. The method includes: receiving downlink control information sent by a first device; wherein the downlink control information is used to schedule a physical uplink shared channel; obtaining frequency domain indication information of the physical uplink shared channel; and determining the frequency domain resource location of the physical uplink shared channel based on the time domain resources occupied by the physical uplink shared channel and the frequency domain indication information. In other words, in the case of uplink transmission across SBFD symbols and non-SBFD symbols, the terminal determines the frequency domain resource location among the SBFD symbols and non-SBFD symbols, ensuring that the allocated frequency domain resources fall within the usable frequency domain resource range, thereby guaranteeing UE transmission performance.

[0061] In some embodiments, step 403, determining the frequency domain resource location of the physical uplink shared channel based on the time domain resources and frequency domain indication information occupied by the physical uplink shared channel, can be achieved through steps A1 and A2, or through step A3:

[0062] Step A1: If the time domain resources of the physical uplink shared channel are located in the second time domain resources, determine the frequency domain resource range based on the second information.

[0063] Step A2: Based on the first information, determine the location of the physical uplink shared channel frequency domain resources within the frequency domain resource interval.

[0064] Step A3: If the time domain resource of the physical uplink shared channel is located in the first time domain resource, determine the location of the physical uplink shared channel frequency domain resource within the first frequency domain resource based on the first information.

[0065] In some embodiments, determining the frequency domain resource interval based on the second information in step A1 can be achieved through step B1, or step B2, or step B3, or step B4, or step B5, or step B7, or step B8:

[0066] Step B1: If M is greater than N and m equals 0, determine the physical resource block index of the frequency domain resource interval with index m as the index from the first physical resource block (PRB) index (PRB 0) of the second frequency domain resource to the first PRB index of the second frequency domain resource plus the size of the first frequency domain resource minus 1.

[0067] in, X2 represents the size of the second frequency domain resource, and X1 represents the size of the first frequency domain resource. The function represents the downward divisibility function, where m is the index of the frequency domain resource interval.

[0068] Step B2: If M is greater than N, m is greater than 0 and less than M, determine the physical resource block index of the frequency domain resource interval with index m as the index from the first physical resource block index of the second frequency domain resource + X1*m + L*m to the first physical resource block index of the second frequency domain resource + X1*(m+1) + L*m-1.

[0069] in,

[0070] Here, L is the distance between two adjacent frequency domain resource intervals, for example, ... Figure 5 The distances between M0 and M1, and between M2 and M1 are shown.

[0071] For example, with Figure 1 Taking the SBFD symbols and non-SBFD symbols available for uplink / downlink transmission as an example, in the uplink transmission scenario, the two repeated transmissions of PUSCH are located in the SBFD symbols and non-SBFD symbols respectively. Using the frequency domain resource allocation method of this application, the first information from the network side allocates PUSCH resources within the X1 bandwidth range according to the first frequency domain resource indication; that is, as shown... Figure 5 As shown, the frequency domain resource (PUSCH Rep#0) corresponding to PUSCH falls within the middle UL subband of Slot#3. The second information on the network side indicates that the second frequency domain resource interval index is 0. Therefore, the PUSCH resource allocation on the second time domain resource is the PUSCH resource allocation within the frequency domain resource interval index 0, corresponding to the X1 bandwidth indicated by the first information, i.e., as shown... Figure 5 As shown, the frequency domain resource (PUSCH Rep#1) corresponding to PUSCH falls within the frequency domain resource range corresponding to M0 of Slot#4, so that PUSCH transmission can proceed normally.

[0072] Step B3: If M equals N, X2 divides X1, and m is 0, determine the PRB index of the frequency domain resource interval with index m as the range from the first PRB index of the second frequency domain resource to the first PRB index of the second frequency domain resource + X1-1.

[0073] Step B4: If M equals N, X2 divides X1, and m is greater than 0 and less than M, determine the PRB index of the frequency domain resource interval with index m as the range from the first PRB index of the second frequency domain resource + X1*m to the first PRB index of the second frequency domain resource + X1*(m+1).

[0074] It should be noted that if the first frequency domain resource is divisible by the second frequency domain resource, it is divided into M frequency domain resource intervals according to the PRB index of the second frequency domain resource in ascending or descending order. The size of each frequency domain resource interval is equal to the size of the first frequency domain resource, and the M frequency domain resource intervals do not overlap. In this case, all the second frequency domain resource PRBs are allocated into the M frequency domain resource intervals.

[0075] For example, if X2 is divisible by X1, then the carrier bandwidth corresponding to Slot#4 symbol / time slot is allocated as follows: Figure 6 The four consecutive frequency domain resource intervals shown are... Figure 6 M0, M1, M2, and M3.

[0076] For example, with Figure 1 Taking the SBFD symbols and non-SBFD symbols available for uplink / downlink transmission as an example, in the uplink transmission scenario, the two repeated transmissions of PUSCH are located in the SBFD symbols and non-SBFD symbols respectively. Using the frequency domain resource allocation method of this application, the first information from the network side allocates PUSCH resources within the X1 bandwidth range according to the first frequency domain resource indication; that is, as shown... Figure 6 As shown, the frequency domain resource (PUSCH Rep#0) corresponding to PUSCH falls within the middle UL subband of Slot#3. The second information on the network side indicates that the second frequency domain resource interval index is 0. Therefore, the PUSCH resource allocation on the second time domain resource is the PUSCH resource allocation within the frequency domain resource interval index 0, corresponding to the X1 bandwidth indicated by the first information, i.e., as shown... Figure 6 As shown, the frequency domain resource (PUSCH Rep#1) corresponding to PUSCH falls within the frequency domain resource range corresponding to M0 of Slot#4, so that PUSCH transmission can proceed normally.

[0077] Step B5: If M equals N, X2 cannot divide X1, and m is 0, determine the PRB index of the frequency domain resource interval with index m as the range from the first PRB index of the second frequency domain resource to the first PRB index of the second frequency domain resource + X1-1.

[0078] Step B6: If M equals N, X2 cannot divide X1, and m is greater than 0 and less than M, determine the PRB index of the frequency domain resource interval with index m as the range from the first PRB index of the second frequency domain resource + X1*m to the first PRB index of the second frequency domain resource + X1*(m+1).

[0079] It should be noted that if the first frequency domain resource is not divisible by the second frequency domain resource, it is divided into M frequency domain resource intervals according to the PRB index of the second frequency domain resource in ascending or descending order. The size of each frequency domain resource interval is equal to the size of the first frequency domain resource, and the M frequency domain resource intervals do not overlap. In this case, some PRBs of the second frequency domain resource are not included in the M frequency domain resource intervals.

[0080] For example, if X2 is not divisible by X1, then the carrier bandwidth corresponding to Slot#4 symbol / time slot is allocated as follows: Figure 7 The four consecutive frequency domain resource intervals shown are... Figure 7 M0, M1, M2, and M3; meanwhile, some PRBs in the carrier bandwidth corresponding to Slot#4 symbol / time slot were not allocated into the M frequency domain resource intervals, that is, some PRBs above M3.

[0081] For example, with Figure 1 Taking the SBFD symbols and non-SBFD symbols available for uplink / downlink transmission as an example, in the uplink transmission scenario, the two repeated transmissions of PUSCH are located in the SBFD symbols and non-SBFD symbols respectively. Using the frequency domain resource allocation method of this application, the first information from the network side allocates PUSCH resources within the X1 bandwidth range according to the first frequency domain resource indication; that is, as shown... Figure 7 As shown, the frequency domain resource (PUSCH Rep#0) corresponding to PUSCH falls within the middle UL subband of Slot#3. The second information on the network side indicates that the second frequency domain resource interval index is 0. Therefore, the PUSCH resource allocation on the second time domain resource is the PUSCH resource allocation within the frequency domain resource interval index 0, corresponding to the X1 bandwidth indicated by the first information, i.e., as shown... Figure 7 As shown, the frequency domain resource (PUSCH Rep#1) corresponding to PUSCH falls within the frequency domain resource range corresponding to M0 of Slot#4, so that PUSCH transmission can proceed normally.

[0082] Step B7: If M is less than N and m is 0, determine the PRB index of the frequency domain resource interval with index m as the range from the first PRB index of the second frequency domain resource to the first PRB index of the second frequency domain resource + X1-1; where X1 represents the size of the first frequency domain resource.

[0083] Step B8: If M is less than N, and m is greater than 0 and less than M, determine the PRB index of the frequency domain resource interval with index m as from the first PRB index of the second frequency domain resource + X1*mL*m to the first PRB index of the second frequency domain resource + X1*(m+1)-L*m-1.

[0084] in, It represents an upward divisibility function.

[0085] Here, L is the overlap distance between two adjacent frequency domain resource intervals, for example, as Figure 8 The overlapping distances between M0 and M1, M1 and M2, M2 and M3, and M3 and M4 are shown.

[0086] For example, with Figure 1 Taking the SBFD symbols and non-SBFD symbols available for uplink / downlink transmission as an example, in the uplink transmission scenario, the two repeated transmissions of PUSCH are located in the SBFD symbols and non-SBFD symbols respectively. Using the frequency domain resource allocation method of this application, the first information from the network side allocates PUSCH resources within the X1 bandwidth range according to the first frequency domain resource indication; that is, as shown... Figure 8 As shown, the frequency domain resource (PUSCH Rep#0) corresponding to PUSCH falls within the middle UL subband of Slot#3. The second information on the network side indicates that the second frequency domain resource interval index is 0. Therefore, the PUSCH resource allocation on the second time domain resource is the PUSCH resource allocation within the frequency domain resource interval index 0, corresponding to the X1 bandwidth indicated by the first information, i.e., as shown... Figure 8 As shown, the frequency domain resource (PUSCH Rep#1) corresponding to PUSCH falls within the frequency domain resource range corresponding to M0 of Slot#4, so that PUSCH transmission can proceed normally.

[0097] In other embodiments of this application, the processing module 903 is configured to determine, if M equals N, X2 divides X1, and m is 0, the physical resource block index of the frequency domain resource interval with index m is from the first physical resource block index of the second frequency domain resource to the first physical resource block index of the second frequency domain resource + X1-1; wherein... X2 represents the size of the second frequency domain resource, and X1 represents the size of the first frequency domain resource.
