Description

Transport block size determination method and communication device

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on January 31, 2024, with application number 202410138229.5 and application name “Transmission Block Size Determination Method and Communication Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a method for determining a transmission block size and a communication device. Background Art

[0003] A transport block is a block of information used to transfer data between the Media Access Control (MAC) layer and the Physical Layer (PHY). To communicate, a terminal device needs to determine the transport block size. For example, before attempting to decode data, the terminal device needs to determine the transport block size (TBS) received on the Physical Downlink Shared Channel (PDSCH).

[0004] In a time-division duplex (TDD) system, the frequency domain resources corresponding to each time unit have the same transmission direction (either uplink or downlink). This allows the frequency domain resources corresponding to each time unit to be used for uplink or downlink transmission. Terminal devices can determine the TBS based on the scheduled transmission resources configured by network equipment. However, in a TDD time-domain configuration, the number of downlink transmission time units is much higher than the number of uplink transmission time units. To meet the need for increased uplink capacity, a network-side subband full-duplex (SBFD) solution has been proposed. This solution divides non-overlapping uplink and downlink subbands within a single carrier, allowing the network to perform uplink reception and downlink transmission in the uplink and downlink subbands corresponding to the same time unit, respectively. This achieves full-duplex operation on the network side. In this case, the time unit is called an SBFD time unit. Within a scheduling session, the network can schedule resources in either SBFD time units or in both SBFD time units and non-SBFD time units. In the case where the transmission resources configured on the network side include SBFD time units in the time domain, further research is needed on how to effectively determine the transmission block size to ensure communication quality in SBFD scenarios. Summary of the Invention

[0005] The embodiments of the present application provide a method for determining the transmission block size and a communication device, which can effectively determine the transmission block size and improve the communication quality of the sub-band full-duplex communication scenario when the transmission resources configured on the network side include sub-band full-duplex time units in the time domain.

[0006] In a first aspect, an embodiment of the present application provides a method for determining a transmission block size, which can be executed by a terminal device or by a device matched with the terminal device, such as a processor, chip, or chip module. The method may include: receiving resource scheduling information, where the resource scheduling information is used to configure uplink or downlink transmission resources, where the transmission resources include sub-band full-duplex time units and non-sub-band full-duplex time units in the time domain; the transmission block size is determined based on the number of transmission resources in the sub-band full-duplex time units and / or the number of transmission resources in the non-sub-band full-duplex time units; wherein the number of uplink transmission resources in the sub-band full-duplex time units includes: the number of frequency domain resources that overlap with the uplink sub-band corresponding to the sub-band full-duplex time units, or the number of downlink transmission resources in the sub-band full-duplex time units includes: the number of frequency domain resources that overlap with the downlink sub-band corresponding to the sub-band full-duplex time units.

[0007] Among them, the terminal device receives resource scheduling information from the network device, which is conducive to determining the transmission block size according to the number of transmission resources configured in the sub-band full-duplex time unit and / or non-sub-band full-duplex resources according to the resource scheduling information; wherein, the number of resources in the sub-band full-duplex time unit used to determine the transmission block size includes the number of frequency domain resources overlapping between the uplink transmission resources and the uplink sub-band, or the number of frequency domain resources overlapping between the downlink transmission resources and the downlink sub-band, and the overlapping frequency domain resources are frequency domain resources that can be used for uplink or downlink, ensuring that the transmission block size can be effectively applied to the resource scheduling across sub-band full-duplex time units and non-sub-band full-duplex time units, thereby improving the communication quality of the sub-band full-duplex communication scenario.

[0008] In one possible implementation, the number of uplink transmission resources in a sub-band full-duplex time unit also includes: the number of time-domain symbols of the uplink transmission resources in the sub-band full-duplex time unit; or, the number of downlink transmission resources in a sub-band full-duplex time unit also includes: the number of time-domain symbols of the downlink transmission resources in the sub-band full-duplex time unit. In other words, the uplink transmission block size is determined based on the number of time-domain symbols of the uplink transmission resources in the sub-band full-duplex time unit and the number of frequency-domain resources that the uplink transmission resources overlap with the uplink sub-band, or, the downlink transmission block size is determined based on the number of time-domain symbols of the downlink transmission resources in the sub-band full-duplex time unit and the number of frequency-domain resources that the downlink transmission resources overlap with the downlink sub-band, ensuring that the transmission block size can adapt to the sub-band full-duplex uplink and downlink time slot ratio and the resource configuration of the network equipment, thereby improving the communication quality of the sub-band full-duplex communication scenario.

[0009] In one possible implementation, the number of transmission resources in a non-subband full-duplex time unit includes: the number of frequency-domain resources corresponding to the transmission resource in the non-subband full-duplex time unit and the number of time-domain symbols of the transmission resource in the non-subband full-duplex time unit. In other words, the transport block size can also be determined based on the number of time-frequency resources of the transmission resource in the non-subband full-duplex time unit to accommodate resource scheduling across subband full-duplex time units and non-subband full-duplex time units, thereby improving communication quality in subband full-duplex communication scenarios.

[0010] In one possible implementation, the transmission block size is determined based on the number of resources of the transmission resource in the sub-band full-duplex time unit and / or the number of resources of the transmission resource in the non-sub-band full-duplex time unit, including: in response to the first time unit in the transmission resource being a sub-band full-duplex time unit, the transmission block size is determined based on the number of resources of the transmission resource in the sub-band full-duplex time unit; or, in response to the first time unit in the transmission resource being a non-sub-band full-duplex time unit, the transmission block size is determined based on the number of resources of the transmission resource in the non-sub-band full-duplex time unit; or, in response to the last time unit in the transmission resource being a sub-band full-duplex time unit, the transmission block size is determined based on the number of resources of the transmission resource in the sub-band full-duplex time unit; or, in response to the last time unit in the transmission resource being a non-sub-band full-duplex time unit, the transmission block size is determined based on the number of resources of the transmission resource in the non-sub-band full-duplex time unit. That is, the transport block size may be determined based on the number of sub-band full-duplex time units or non-sub-band full-duplex time units according to the sub-band full-duplex type of the first or last time unit in the transmission resources configured by the network device.

[0011] In one possible implementation, the transport block size is determined based on the number of transmission resources in a sub-band full-duplex time unit and / or the number of transmission resources in a non-sub-band full-duplex time unit, including: based on a configuration in first configuration information or an indication of a first default value, the transport block size is determined based on the number of transmission resources in a sub-band full-duplex time unit or the number of transmission resources in a non-sub-band full-duplex time unit. Optionally, the first configuration information or the first default value is sent by a network device to a terminal device or is predefined on the terminal device. Based on the configuration in the first configuration information or the indication of the first default value, the type of resource quantity used to determine the transport block size can be conveniently determined.

[0012] In one possible implementation, the transport block size is determined based on the number of transmission resources in sub-band full-duplex time units and / or the number of transmission resources in non-sub-band full-duplex time units. This includes: in response to the number of sub-band full-duplex time units occupied being greater than the number of non-sub-band full-duplex time units occupied in the transmission resource, the transport block size is determined based on the number of transmission resources in sub-band full-duplex time units; or in response to the number of non-sub-band full-duplex time units occupied being greater than the number of sub-band full-duplex time units occupied in the transmission resource, the transport block size is determined based on the number of transmission resources in non-sub-band full-duplex time units. In other words, the transport block size may be determined based on the number of resources in the transmission resource that occupies the largest number of time units.

[0013] In one possible implementation, transmission resources are used for repeated transmissions, and a transmission block size applies to both transmission opportunities corresponding to sub-band full-duplex time units and transmission opportunities corresponding to non-sub-band full-duplex time units. A network device configures transmission resources for repeated transmissions, and a transmission block size determined by a terminal device can be applied to both sub-band full-duplex time units and non-sub-band full-duplex time units.

[0014] In one possible implementation, a transmission block is transmitted over multiple time slots; the transmission block size is determined based on the number of resources of the transmission resources in the sub-band full-duplex time unit and / or the number of resources of the transmission resources in the non-sub-band full-duplex time unit, including: the transmission block size is determined based on the number of resources of the transmission resources in the sub-band full-duplex time unit and first indication information, the first indication information is carried by the resource scheduling information, and the first indication information is used to indicate the number of time slots occupied by the transmission block; or, the transmission block size is determined based on the number of resources of the transmission resources in the non-sub-band full-duplex time unit and the first indication information; or, the transmission block size is determined based on the number of resources of the transmission resources in the sub-band full-duplex time unit and the number of resources of the transmission resources in the non-sub-band full-duplex time unit. That is, when supporting a transmission block processing mechanism across multiple time slots, the transmission block size can be determined based on the number of resources of the transmission resources in the sub-band full-duplex time unit and the first indication information, or the number of resources of the transmission resources in the non-sub-band full-duplex time unit and the first indication information, or the number of resources of the transmission resources in the sub-band full-duplex time unit and the number of resources in the non-sub-band full-duplex time unit.

[0015] In a second aspect, embodiments of the present application provide a method for determining a transport block size, which can be executed by a terminal device, or by a device compatible with the terminal device, such as a processor, chip, or chip module. The method may include: receiving resource scheduling information, where the resource scheduling information is used to configure uplink or downlink transmission resources, where the transmission resources include sub-band full-duplex time units in the time domain; wherein the uplink transport block size is determined based on the number of frequency domain resources overlapping between the uplink transmission resource and the uplink sub-band corresponding to the sub-band full-duplex time unit, or the downlink transport block size is determined based on the number of frequency domain resources overlapping between the downlink transmission resource and the downlink sub-band corresponding to the sub-band full-duplex time unit.

[0016] Among them, the terminal device receives resource scheduling information from the network device, which is conducive to determining the transmission block size according to the number of resources of the transmission resources configured by the resource scheduling information in the sub-band full-duplex time unit; wherein, the uplink transmission block size is determined based on the number of frequency domain resources overlapping between the uplink transmission resources and the uplink sub-band corresponding to the sub-band full-duplex time unit, or the downlink transmission block size is determined based on the number of frequency domain resources overlapping between the downlink transmission resources and the downlink sub-band corresponding to the sub-band full-duplex time unit, ensuring that the transmission block size can be effectively applied to the resource scheduling situation of the sub-band full-duplex time unit, thereby improving the communication quality of the sub-band full-duplex communication scenario.

[0017] In one possible implementation, the downlink transmission block size is determined based on the number of frequency domain resources that overlap the downlink transmission resource and the downlink sub-band corresponding to the sub-band full-duplex time unit, including: the downlink transmission block size is determined based on the number of partial frequency domain resources that overlap the transmission resource and the downlink sub-band; wherein the partial frequency domain resources are determined based on the second configuration information, predefined information or the second default value. For example, for a terminal device that cannot support non-continuous downlink transmission across the uplink sub-band under the resources corresponding to the sub-band full-duplex time unit, partial frequency domain resources of a sub-band in the above-mentioned overlapping frequency domain resources can be selected based on the second configuration information, predefined information or the second default value to determine the transmission block size. Optionally, the second configuration information or the second default value is sent by the network device to the terminal device, or is predefined on the terminal device.

[0018] In a third aspect, an embodiment of the present application provides a method for determining a transmission block size, which can be executed by a network device or by a device compatible with the network device, such as a processor, chip, or chip module. The method may include: sending resource scheduling information, where the resource scheduling information is used to configure uplink or downlink transmission resources, where the transmission resources include sub-band full-duplex time units and non-sub-band full-duplex time units in the time domain; the transmission block size is determined based on the number of transmission resources in the sub-band full-duplex time units and / or the number of transmission resources in the non-sub-band full-duplex time units; wherein the number of uplink transmission resources in the sub-band full-duplex time units includes: the number of frequency domain resources that overlap with the uplink sub-band corresponding to the sub-band full-duplex time unit, or the number of downlink transmission resources in the sub-band full-duplex time units includes: the number of frequency domain resources that overlap with the downlink sub-band corresponding to the sub-band full-duplex time unit.

[0019] Among them, the network device sends resource scheduling information to the terminal device, which is beneficial for the terminal device to determine the transmission block size according to the number of transmission resources in the sub-band full-duplex time unit and / or non-sub-band full-duplex time unit configured by the resource scheduling information; wherein, the number of resources in the sub-band full-duplex time unit used to determine the transmission block size includes the number of frequency domain resources overlapping between the uplink transmission resources and the uplink sub-band, or the number of frequency domain resources overlapping between the downlink transmission resources and the downlink sub-band, and the overlapping frequency domain resources are frequency domain resources that can be used for uplink or downlink, ensuring that the transmission block size can be effectively applied to the resource scheduling across sub-band full-duplex time units and non-sub-band full-duplex time units, thereby improving the communication quality of the sub-band full-duplex communication scenario.

[0020] In one possible implementation, the number of uplink transmission resources in a sub-band full-duplex time unit also includes: the number of time-domain symbols of the uplink transmission resources in the sub-band full-duplex time unit; or, the number of downlink transmission resources in a sub-band full-duplex time unit also includes: the number of time-domain symbols of the downlink transmission resources in the sub-band full-duplex time unit. In other words, the uplink transmission block size is determined based on the number of time-domain symbols of the uplink transmission resources in the sub-band full-duplex time unit and the number of frequency-domain resources that the uplink transmission resources overlap with the uplink sub-band, or, the downlink transmission block size is determined based on the number of time-domain symbols of the downlink transmission resources in the sub-band full-duplex time unit and the number of frequency-domain resources that the downlink transmission resources overlap with the downlink sub-band, ensuring that the transmission block size can adapt to the sub-band full-duplex uplink and downlink time slot ratio and the resource configuration of the network equipment, thereby improving the communication quality of the sub-band full-duplex communication scenario.

[0021] In one possible implementation, the number of transmission resources in a non-subband full-duplex time unit includes: the number of frequency-domain resources corresponding to the transmission resource in the non-subband full-duplex time unit and the number of time-domain symbols of the transmission resource in the non-subband full-duplex time unit. In other words, the transport block size can also be determined based on the number of time-frequency resources of the transmission resource in the non-subband full-duplex time unit to accommodate resource scheduling across subband full-duplex time units and non-subband full-duplex time units, thereby improving communication quality in subband full-duplex communication scenarios.

[0022] In one possible implementation, the transmission block size is determined based on the number of resources of the transmission resource in the sub-band full-duplex time unit and / or the number of resources of the transmission resource in the non-sub-band full-duplex time unit, including: in response to the first time unit in the transmission resource being a sub-band full-duplex time unit, the transmission block size is determined based on the number of resources of the transmission resource in the sub-band full-duplex time unit; or, in response to the first time unit in the transmission resource being a non-sub-band full-duplex time unit, the transmission block size is determined based on the number of resources of the transmission resource in the non-sub-band full-duplex time unit; or, in response to the last time unit in the transmission resource being a sub-band full-duplex time unit, the transmission block size is determined based on the number of resources of the transmission resource in the sub-band full-duplex time unit; or, in response to the last time unit in the transmission resource being a non-sub-band full-duplex time unit, the transmission block size is determined based on the number of resources of the transmission resource in the non-sub-band full-duplex time unit. That is, the transport block size may be determined based on the number of sub-band full-duplex time units or non-sub-band full-duplex time units according to the sub-band full-duplex type of the first or last time unit in the transmission resources configured by the network device.

[0023] In one possible implementation, the transport block size is determined based on the number of transmission resources in a sub-band full-duplex time unit and / or the number of transmission resources in a non-sub-band full-duplex time unit, including: based on a configuration in first configuration information or an indication of a first default value, the transport block size is determined based on the number of transmission resources in a sub-band full-duplex time unit or the number of transmission resources in a non-sub-band full-duplex time unit. Optionally, the first configuration information or the first default value is sent by a network device to a terminal device or is predefined on the terminal device. Based on the configuration in the first configuration information or the indication of the first default value, the type of resource quantity used to determine the transport block size can be conveniently determined.

[0024] In one possible implementation, the transport block size is determined based on the number of transmission resources in sub-band full-duplex time units and / or the number of transmission resources in non-sub-band full-duplex time units. This includes: in response to the number of sub-band full-duplex time units occupied being greater than the number of non-sub-band full-duplex time units occupied in the transmission resource, the transport block size is determined based on the number of transmission resources in sub-band full-duplex time units; or in response to the number of non-sub-band full-duplex time units occupied being greater than the number of sub-band full-duplex time units occupied in the transmission resource, the transport block size is determined based on the number of transmission resources in non-sub-band full-duplex time units. In other words, the transport block size may be determined based on the number of resources in the transmission resource that occupies the largest number of time units.

[0025] In one possible implementation, transmission resources are used for repeated transmissions, and a transmission block size applies to both transmission opportunities corresponding to sub-band full-duplex time units and transmission opportunities corresponding to non-sub-band full-duplex time units. A network device configures transmission resources for repeated transmissions, and a transmission block size determined by a terminal device can be applied to both sub-band full-duplex time units and non-sub-band full-duplex time units.

[0026] In one possible implementation, a transmission block is transmitted over multiple time slots; the transmission block size is determined based on the number of resources of the transmission resources in the sub-band full-duplex time unit and / or the number of resources of the transmission resources in the non-sub-band full-duplex time unit, including: the transmission block size is determined based on the number of resources of the transmission resources in the sub-band full-duplex time unit and first indication information, the first indication information is carried by the resource scheduling information, and the first indication information is used to indicate the number of time slots occupied by the transmission block; or, the transmission block size is determined based on the number of resources of the transmission resources in the non-sub-band full-duplex time unit and the first indication information; or, the transmission block size is determined based on the number of resources of the transmission resources in the sub-band full-duplex time unit and the number of resources of the transmission resources in the non-sub-band full-duplex time unit. That is, when supporting a transmission block processing mechanism across multiple time slots, the transmission block size can be determined based on the number of resources of the transmission resources in the sub-band full-duplex time unit and the first indication information, or the number of resources of the transmission resources in the non-sub-band full-duplex time unit and the first indication information, or the number of resources of the transmission resources in the sub-band full-duplex time unit and the number of resources in the non-sub-band full-duplex time unit.

[0069] Secondly, the relevant concepts involved in the embodiments of this application are explained.

[0070] 1. Subband Full Duplex (SBFD) time unit and non-Subband Full Duplex (non-SBFD) time unit

[0071] In a time division duplex (TDD) system, the frequency domain resources corresponding to each time unit have the same transmission direction, that is, both uplink and downlink, so that the frequency domain resources corresponding to each time unit can be effectively used for uplink transmission or downlink transmission, that is, for transmission in one transmission direction. However, in the TDD time domain configuration, the number of downlink transmission time units is much higher than the number of uplink transmission time units. In order to meet the demand for uplink capacity enhancement, a network-side SBFD solution is proposed. That is, the network side divides non-overlapping uplink subbands (UL subbands) and downlink subbands (DL subbands) in the frequency domain within a single carrier, so that the network side performs uplink reception and downlink transmission respectively in the uplink subband and downlink subband corresponding to the same time unit, thereby achieving full duplex on the network side. In this case, the time unit can be called an SBFD time unit; for the terminal side, it still supports only uplink transmission in the uplink subband or downlink reception in the downlink subband in one time unit. Optionally, the time unit can be a symbol, a time slot or a subframe. Accordingly, the SBFD time unit can be called an SBFD symbol, an SBFD time slot or an SBFD subframe. This document uses the time slot as an example for illustration. Please refer to Figure 2, which shows a schematic diagram of the uplink and downlink TDD configuration of time-frequency resources provided in an embodiment of the present application. In Figure 2, the horizontal axis represents the time domain, represented by t, and the vertical axis represents the frequency domain, represented by f. The gNB divides the carrier corresponding to slot n into uplink and downlink subbands, with U representing the uplink subband and D representing the downlink subband. Therefore, slot n is an SBFD time unit.

[0072] Correspondingly, the frequency domain resources corresponding to a time unit can only support transmission in one direction, that is, the time unit has no uplink subband, and the time unit can be called a non-SBFD time unit. Optionally, the non-SBFD time unit can be called a non-SBFD symbol, a non-SBFD time slot, or a non-SBFD subframe. Please refer to Figure 3, which is a schematic diagram of the uplink and downlink TDD configuration of another time-frequency resource provided in an embodiment of the present application. In Figure 3, the horizontal axis is the time domain, represented by t, and the vertical axis is the frequency domain, represented by f. The carriers corresponding to slot 0-slot 3 include uplink subbands and downlink subbands, that is, slot 0-slot 3 are SBFD time units, and the frequency domain resources corresponding to slot 4 can only be used for uplink transmission, that is, slot 4 is a non-SBFD time unit. In the frequency domain resources corresponding to the non-SBFD time unit, U indicates that all frequency domain resources corresponding to the time unit can only be used for uplink transmission. In the frequency domain resources corresponding to the SBFD time unit, D indicates the downlink subband, and U indicates the uplink subband.

[0073] Optionally, a frequency domain guard band may be configured between the uplink subband and the downlink subband in Figures 2 and 3. The frequency domain guard band is provided to suppress inter-subband cross-link interference from the downlink subband to the uplink subband, and the frequency domain guard band is not used for uplink or downlink transmission.

[0074] 2. Transport Block (TB) and Transport Block Size (TBS)

[0075] A TB is an information block used to transfer data between the Media Access Control (MAC) layer and the Physical (PHY) layer. TBS, also known as transport block size, refers to the size of this information block. For example, it can refer to the number of bits of information contained in the information block.

[0076] In order to communicate, the terminal device needs to determine the transport block size. For example, before attempting to decode data, the terminal device needs to determine the transport block size TBS received on the physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH). The terminal device first determines the number of resource elements (REs) allocated for PDSCH or PUSCH in a physical resource block (PRB) within a time slot using formula (1): RE :

[0077] in, is the number of subcarriers in a PRB and is equal to 12, is the number of time domain symbols allocated for PDSCH or PUSCH in each time slot, is the number of demodulation reference signal (DM-RS) REs per PRB during the scheduling duration, including the overhead of the DM-RS CDM group without data. The overhead configured by the higher-level parameter xOverhead, for example, the overhead configured by the higher-level parameter xOverhead in PDSCH-ServingCellConfig (PDSCH serving cell configuration) or PUSCH-ServingCellConfig (PUSCH serving cell configuration). The higher-level parameter xOverhead can be selected from 0, 6, 12 or 18. If the higher-level parameter xOverhead is not configured, then Can be set to 0. If PDSCH is scheduled by a Physical Downlink Control Channel (PDCCH) with a CRC (Cyclic Redundancy Check) scrambled by SI-RNTI (System Information Radio Network Temporary Identifier), RA-RNTI (Radio Access Radio Network Temporary Identifier), MsgB-RNTI (Message B Radio Network Temporary Identifier), or P-RNTI (Physical Radio Network Temporary Identifier), then Can be assumed to be 0. For uplink message 3 (Msg3) transmission, Can be set to 0.

[0078] The terminal device determines the total number N of REs allocated for PDSCH or PUSCH in a time slot using formula (2): RE : N RE =min(156,N' RE )·n PRB (2)

[0079] Among them, n PRB is the total number of PRBs allocated to the terminal device.

[0080] The total number of REs N allocated to PDSCH or PUSCH by the terminal device is calculated by formula (3): RE Converted to the number of non-quantized information bits N info : N info =N RE *R*Q m *v (3)

[0081] Among them, R is the target code rate, Q m is the modulation order, and v is the number of transmission layers.

[0082] The terminal device will use the number of non-quantized information bits N info Quantify the number of information bits N' transmitted for PDSCH or PUSCH info , thus according to N' info Get TBS.

[0083] Among them, in repetition, for a terminal device configured with the high-level parameter repetitionScheme and repetitionScheme set to "fdmSchemeB", when the code point of the "Transmission Configuration Indication" field of the DCI indicates two transmission configuration indication (TCI) states and the "Antenna Port" field of the DCI indicates a DM-RS in a CDM (Code Division Multiplexing) group, N is determined by the number of allocated PRBs corresponding to the first TCI. RE , that is, N RE =min(DI,N' RE )·n PRB n in PRB The TBS of the PDSCH or PUSCH transmission opportunity associated with the first TCI state, determined based on the number of allocated PRBs corresponding to the first TCI, is also applicable to the PDSCH or PUSCH transmission opportunity associated with the second TCI.

[0084] In repetition, for a terminal device configured with the high-level parameter repetitionScheme and repetitionScheme set to "tdmSchemeA", when the code point of the "Transmission Configuration Indication" field of the DCI indicates two TCI states and the "Antenna Port" field of the DCI indicates a DM-RS in one CDM group, N' is determined by the number of symbols allocated for PDSCH or PUSCH in the time slot corresponding to the first TCI state. RE ,Right now in The TBS of the PDSCH or PUSCH transmission opportunity associated with the first TCI state, determined based on the number of symbols allocated to the PDSCH in the time slot corresponding to the first TCI state, is also applicable to the PDSCH or PUSCH transmission opportunity associated with the second TCI.

[0085] For TB processing over multi-slot (TBoMS), the total number of REs allocated for PUSCH is determined by formula (4): RE : N RE =N*min(156,N' RE )·n PRB (4)

[0086] Where N is the number of time slots occupied by the transport block indicated by the parameter numberOfSlotsTBoMS.

[0087] The above formula for determining the TBS size includes the number of time domain symbols in each time slot configured for the terminal device. and the total number of PRBs n PRB .

[0088] In a time division duplex (TDD) system, the frequency domain resources of a TDD carrier must have the same transmission direction in the same time unit, that is, both uplink and downlink, so that the uplink resources configured for the terminal device by the network side can be effectively used for uplink transmission, and the configured downlink resources can be effectively used for downlink transmission. That is, the number of time domain symbols and the total number of PRBs in each time slot configured by the network side for the terminal device are the number of scheduling resources used to determine the TBS. and n PRB .

[0089] After the SBFD solution is proposed, the primary scheduling resources configured by network devices for terminal devices may fall into the following two situations:

[0090] In case 1, the scheduled PDSCH resource overlaps with the uplink subband and frequency domain guard band in the resources corresponding to the SBFD time unit, or the scheduled PUSCH resource overlaps with the downlink subband and frequency domain guard band in the resources corresponding to the SBFD time unit.

[0091] Please refer to Figure 4, which is a schematic diagram of a network device scheduling PDSCH according to an embodiment of the present application. As shown in Figure 4, the PDSCH configured by the network device for the terminal device overlaps with the uplink subband and frequency domain guard band corresponding to the SBFD time unit. In the frequency domain resources corresponding to the SBFD time unit, D represents the downlink subband, U represents the uplink subband, and the frequency domain interval between the downlink subband and the uplink subband is the frequency domain guard band.

[0092] Please refer to Figure 5, which is a schematic diagram of a network device scheduling PUSCH according to an embodiment of the present application. As shown in Figure 5, the PUSCH configured by the network device for the terminal device overlaps with the downlink subband and frequency domain guard band corresponding to the SBFD time unit. In the frequency domain resources corresponding to the SBFD time unit, D represents the downlink subband, U represents the uplink subband, and the frequency domain interval between the downlink subband and the uplink subband is the frequency domain guard band.

[0093] In case 2, the scheduled PDSCH is transmitted in the SBFD time unit and the non-SBFD time unit, or the scheduled PUSCH is transmitted in the SBFD time unit and the non-SBFD time unit.

[0094] Please refer to Figure 6, which is a schematic diagram of another network device scheduling PDSCH provided in an embodiment of the present application. As shown in Figure 6, the PDSCH configured by the network device for the terminal device is transmitted in SBFD time units and non-SBFD time units. In the frequency domain resources corresponding to the non-SBFD time unit, D indicates that all frequency domain resources corresponding to the time unit can only be used for downlink transmission, and U indicates that all frequency domain resources corresponding to the time unit can only be used for uplink transmission. In the frequency domain resources corresponding to the SBFD time unit, D represents the downlink subband, and U represents the uplink subband.

[0095] Please refer to Figure 7, which is a schematic diagram of another network device scheduling PUSCH provided in an embodiment of the present application. As shown in Figure 7, the PUSCH configured by the network device for the terminal device is transmitted in SBFD time units and non-SBFD time units. In the frequency domain resources corresponding to the non-SBFD time unit, D indicates that all frequency domain resources corresponding to the time unit can only be used for downlink transmission, and U indicates that all frequency domain resources corresponding to the time unit can only be used for uplink transmission. In the frequency domain resources corresponding to the SBFD time unit, D represents the downlink subband, and U represents the uplink subband.

[0096] In case 2, for repetition and TBoMS, it is necessary to calculate the TBS applicable to the transmission opportunities corresponding to the SBFD time unit and the non-SBFD time unit.

[0097] In Cases 1 and 2, not all scheduled PDSCH resources can be effectively used for downlink transmission due to potential overlap with uplink subbands and frequency domain guard bands. Similarly, not all scheduled PUSCH resources can be effectively used for uplink transmission due to potential overlap with downlink subbands and frequency domain guard bands. The number of resources configured by the network device for uplink or downlink transmission of a terminal device cannot be directly applied to the aforementioned formula to effectively calculate TBS. Further research is needed to determine the effective transport block size to ensure communication quality in SBFD scenarios, especially when the transmission resources configured by the network device include SBFD time units in the time domain.

[0098] In view of this, a TBS determination method is proposed, which can effectively determine the transport block size when the transmission resources configured on the network side include SBFD time units in the time domain, thereby improving the communication quality in sub-band full-duplex communication scenarios.

[0099] The following is a detailed description of the resource determination method provided in an embodiment of the present application based on the system architecture shown in Figure 1. The execution subjects in the embodiments of the present application can be terminal devices and network devices. Alternatively, the execution subjects in the embodiments of the present application can be devices that match the terminal devices, such as processors, chips, or chip modules, and devices that match the network devices, such as processors, chips, or chip modules. The following description uses terminal devices and network devices as examples.

[0100] Please refer to FIG8 , which is a flowchart of a TBS determination method provided in an embodiment of the present application. The method may include but is not limited to the following steps:

[0101] 801. A network device sends resource scheduling information to a terminal device. The resource scheduling information is used to configure uplink or downlink transmission resources. The transmission resources include SBFD time units and non-SBFD time units in the time domain. Correspondingly, the terminal device receives the resource scheduling information from the network device.

[0102] Optionally, in the case of dynamic resource scheduling, resource scheduling information can be carried in the scheduling DCI. In the case of semi-static resource scheduling, resource scheduling information can be carried in higher-layer signaling, such as in Radio Resource Control (RRC) signaling. Resource scheduling information can also be carried in corresponding control information or signaling according to other resource scheduling methods, which are not limited here.

[0103] Optionally, the uplink transmission resource may be a PUSCH, and the downlink transmission resource may be a PDSCH.

[0104] Optionally, the method may further include the following steps:

[0105] 802. The terminal device determines a TBS based on the number of transmission resources in the SBFD time unit and / or the number of transmission resources in the non-SBFD time unit.

[0106] The terminal device can determine the TBS in the following ways:

[0107] In the first method, the terminal device determines the TBS based on the number of transmission resources in the SBFD time unit;

[0108] In the second method, the terminal device determines the TBS based on the number of transmission resources in the non-SBFD time unit;

[0109] In a third manner, the terminal device determines the TBS based on the number of transmission resources in the SBFD time unit and the number of transmission resources in the non-SBFD time unit.

[0110] For the first and third methods, the number of resources used to determine the TBS includes the number of resources of the transmission resources in the SBFD time unit. In the case where the resource scheduling information configures the uplink transmission resources, the number of resources of the transmission resources in the SBFD time unit includes: the number of frequency domain resources of the uplink transmission resources overlapping with the uplink sub-band corresponding to the SBFD time unit; optionally, the number of resources of the transmission resources in the SBFD time unit also includes: the number of time domain symbols of the uplink transmission resources within the SBFD time unit. Optionally, the number of frequency domain resources of the uplink transmission resources overlapping with the uplink sub-band corresponding to the SBFD time unit may refer to: the number of frequency domain resources of the uplink transmission resources overlapping with the uplink sub-band corresponding to one SBFD time unit; the number of time domain symbols of the uplink transmission resources within the SBFD time unit may refer to: the number of symbols of the uplink transmission resources within one SBFD time unit.

[0111] When resource scheduling information configures downlink transmission resources, the number of transmission resources in an SBFD time unit includes: the number of frequency domain resources overlapping with the downlink subband corresponding to the SBFD time unit; optionally, the number of transmission resources in an SBFD time unit also includes: the number of time domain symbols of the downlink transmission resources within the SBFD time unit. Optionally, the number of frequency domain resources overlapping with the downlink subband corresponding to the SBFD time unit may refer to: the number of frequency domain resources overlapping with the downlink subband corresponding to one SBFD time unit; the number of time domain symbols of the downlink transmission resources within an SBFD time unit may refer to: the number of symbols of the downlink transmission resources within one SBFD time unit.

[0112] For the second and third methods, the number of resources used to determine the TBS includes the number of resources of the transmission resources in the non-SBFD time unit. In the case where the resource scheduling information configures uplink or downlink transmission resources, the number of resources of the transmission resources in the non-SBFD time unit includes: the number of frequency domain resources corresponding to the transmission resources in the non-SBFD time unit and the number of time domain symbols (symbols) of the transmission resources in the non-SBFD time unit. Optionally, the number of frequency domain resources corresponding to the transmission resources in the non-SBFD time unit may refer to: the number of frequency domain resources corresponding to the transmission resources in one non-SBFD time unit; the number of time domain symbols (symbols) of the transmission resources in the non-SBFD time unit may refer to: the number of time domain symbols (symbols) of the transmission resources in one non-SBFD time unit.

[0113] The number of frequency domain resources refers to the number of PRBs.

[0114] The terminal device can determine whether to use the first or second method to determine the TBS in the following ways:

[0115] Mode 1: The terminal device determines the TBS using the first or second mode described above in response to the type of the first or last time unit in the transmission resource configured by the resource scheduling information.

[0116] Optionally, in response to the first time unit in the transmission resource being a SBFD time unit, the terminal device determines the TBS based on the number of resources of the transmission resource in the SBFD duplex time unit, that is, determines the TBS by the first method mentioned above.

[0117] Optionally, in response to the first time unit in the transmission resource being a non-SBFD duplex time unit, the terminal device determines the TBS based on the number of resources of the transmission resource in the non-SBFD duplex time unit, that is, determines the TBS by the second method mentioned above.

[0118] Optionally, in response to the last time unit in the transmission resource being a SBFD time unit, the terminal device determines the TBS based on the number of resources of the transmission resource in the SBFD time unit, that is, determines the TBS through the first method mentioned above.

[0119] Optionally, in response to the last time unit in the transmission resource being a non-SBFD duplex time unit, the terminal device determines the TBS based on the number of resources of the transmission resource in the non-SBFD duplex time unit, that is, determines the TBS by the second method mentioned above.

[0120] Mode 2: The terminal device determines the TBS according to the number of transmission resources in the SBFD time unit or the number of transmission resources in the non-SBFD time unit based on the configuration of the first configuration information or the indication of the first default value.

[0121] Optionally, the first configuration information or the first default value is sent by the network device to the terminal device, or is predefined on the terminal device.

[0122] For example, the first configuration information includes bit information, where the bit information is 1, which configures or indicates that the TBS is determined based on the number of transmission resources in the SBFD time unit; and the bit information is 0, which configures or indicates that the TBS is determined based on the number of transmission resources in the non-SBFD time unit. 0 and 1 can also be interchanged for indication or configuration. For another example, the first default value is 1, which indicates that the TBS is determined based on the number of transmission resources in the SBFD time unit; and the bit information is 0, which indicates that the TBS is determined based on the number of transmission resources in the non-SBFD time unit. 0 and 1 can also be interchanged for indication.

[0123] In mode 3, the terminal device determines the TBS based on the number of transmission resources in SBFD time units or the number of transmission resources in non-SBFD time units, based on the time unit type that occupies the largest number of transmission resources. Time unit types include SBFD time units and non-SBFD time units.

[0124] Optionally, in response to the number of occupied SBFD time units in the transmission resource being greater than the number of occupied non-SBFD time units, the terminal device determines the TBS based on the number of resources of the transmission resource in the SBFD time units. For example, the transmission resource includes 10 time units, of which 6 are SBFD time units and 4 are non-SBFD time units, and the number of occupied SBFD time units is greater than the number of occupied non-SBFD time units. The TBS is determined based on the number of resources of the transmission resource in the SBFD time units.

[0125] Optionally, in response to the number of occupied non-SBFD time units in the transmission resource being greater than the number of occupied SBFD time units, the terminal device determines the transport block size based on the number of resources of the transmission resource in the non-SBFD time units. For example, the transmission resource includes 10 time units, of which 4 are SBFD time units and 6 are non-SBFD time units, and the number of occupied non-SBFD time units is greater than the number of occupied SBFD time units. The TBS is determined based on the number of resources of the transmission resource in the non-SBFD time units.

[0126] In mode 4, the terminal device randomly selects the number of transmission resources in the SBFD time unit or the number of transmission resources in the non-SBFD time unit to determine the TBS.

[0127] The transmission resources configured by the resource scheduling information include both SBFD time units and non-SBFD time units in the time domain. This means that the network device schedules resources across both SBFD time units and non-SBFD time units, which includes the aforementioned cases 1 and 2. Specifically, there are two cases in which the network device schedules resources across both SBFD time units and non-SBFD time units:

[0128] In the first case, the transmission resources configured by the resource scheduling information are used for repeated transmissions. The repeated transmissions include uplink repeated transmissions or downlink repeated transmissions. The TBSs determined using the first, second, and third methods can be applied to both the transmission timing corresponding to the SBFD time unit and the transmission timing corresponding to the non-SBFD time unit.

[0129] Optionally, the TBS is determined in the first manner. For example, when the TBS is determined in the first manner according to any one of the manners 1 to 4, the symbol number of the uplink transmission resource in the SBFD time unit can be used as Substitute into formula (1), and take the number of PRBs in the frequency domain resources where the uplink transmission resource overlaps with the uplink subband corresponding to the SBFD time unit as n PRB Substitute into formula (2) to calculate the uplink TBS. For another example, the number of symbols of downlink transmission resources in the SBFD time unit can be used as Substitute into formula (1), and take the number of PRBs in the frequency domain resources where the downlink transmission resource overlaps with the downlink subband corresponding to the SBFD time unit as n PRB Substitute into formula (2) to calculate the downlink TBS. The TBS applicable to the transmission opportunity corresponding to the SBFD time unit, determined based on the number of transmission resources in the SBFD time unit, is also applicable to the transmission opportunity corresponding to the non-SBFD time unit.

[0130] Optionally, the TBS is determined in the second manner. For example, when the TBS is determined in the second manner according to any one of the manners 1 to 4, the number of symbols of the transmission resource in the non-SBFD time unit can be used as Substitute into formula (1) and take the number of PRBs of transmission resources in the non-SBFD time unit as n PRBSubstitute into formula (2) to calculate the uplink or downlink TBS. The TBS applicable to the transmission opportunity corresponding to the non-SBFD time unit, determined based on the number of transmission resources in the non-SBFD time unit, also applies to the transmission opportunity corresponding to the SBFD time unit.

[0131] Optionally, the TBS can be determined in a third way, where the number of symbols of uplink transmission resources in the SBFD time unit is used as Substitute into formula (1), and take the number of PRBs in the frequency domain resources where the uplink transmission resource overlaps with the uplink subband corresponding to the SBFD time unit as n PRB Substitute into formula (2) to calculate the uplink TBS corresponding to the SBFD time unit; and the number of symbols of transmission resources in the non-SBFD time unit can be used as Substitute into formula (1) and take the number of PRBs of transmission resources in the non-SBFD time unit as n PRB Substitute into formula (2) to calculate the uplink TBS corresponding to the non-SBFD time unit. Then, take the average of the sum of the uplink TBS corresponding to the SBFD time unit and the uplink TBS corresponding to the non-SBFD time unit to obtain the uplink TBS applicable to the transmission opportunities corresponding to the non-SBFD time unit and the transmission opportunities corresponding to the SBFD time unit.

[0132] Optionally, the TBS can be determined in a third way, where the symbol number of the uplink transmission resource is used as Substitute into formula (1), and take the number of PRBs in the frequency domain resources where the uplink transmission resource overlaps with the uplink subband corresponding to the SBFD time unit as n PRB Substitute into formula (2) to calculate the uplink TBS corresponding to the SBFD time unit; and the symbol number of the uplink transmission resource can be used as Substitute into formula (1) and take the number of PRBs of transmission resources in the non-SBFD time unit as n PRB Substitute into formula (2) to calculate the uplink TBS corresponding to the non-SBFD time unit. Then, take the average of the sum of the uplink TBS corresponding to the SBFD time unit and the uplink TBS corresponding to the non-SBFD time unit to obtain the uplink TBS applicable to the transmission opportunities corresponding to the non-SBFD time unit and the transmission opportunities corresponding to the SBFD time unit.

Then, take the average of the sum of the downlink TBS corresponding to the SBFD time unit and the downlink TBS corresponding to the non-SBFD time unit to obtain the downlink TBS applicable to the transmission timing corresponding to the non-SBFD time unit and the transmission timing corresponding to the SBFD time unit.

[0134] Optionally, the TBS can be determined in a third way, where the number of symbols of downlink transmission resources can be used as Substitute into formula (1), and take the number of PRBs in the frequency domain resources where the downlink transmission resource overlaps with the downlink subband corresponding to the SBFD time unit as n PRB Substitute into formula (2) to calculate the downlink TBS corresponding to the SBFD time unit; and use the number of symbols of downlink transmission resources as Substitute into formula (1) and take the number of PRBs of transmission resources in the non-SBFD time unit as n PRB Substitute into formula (2) to calculate the downlink TBS corresponding to the non-SBFD time unit. Then, take the average of the sum of the downlink TBS corresponding to the SBFD time unit and the downlink TBS corresponding to the non-SBFD time unit to obtain the downlink TBS applicable to the transmission timing corresponding to the non-SBFD time unit and the transmission timing corresponding to the SBFD time unit.

[0135] Optionally, the TBS can be determined in a third way by taking the average of the sum of the number of symbols of the uplink transmission resources in the SBFD time unit and the number of symbols of the uplink transmission resources in the non-SBFD time unit, as Substitute into formula (1), and take the average of the sum of the number of PRBs in the frequency domain resources where the uplink transmission resources overlap with the uplink subband corresponding to the SBFD time unit and the number of PRBs in the uplink transmission resources in the non-SBFD time unit, as n PRB Substitute into formula (2) to calculate the uplink TBS.

[0136] Optionally, the TBS can be determined in a third way, where the symbol number of the uplink transmission resource is used as Substitute into formula (1), and take the average of the sum of the number of PRBs in the frequency domain resources where the uplink transmission resources overlap with the uplink subband corresponding to the SBFD time unit and the number of PRBs in the uplink transmission resources in the non-SBFD time unit, as n PRB Substitute into formula (2) to calculate the uplink TBS.

[0137] Optionally, the TBS can be determined in a third way by taking the average of the sum of the number of symbols of the downlink transmission resources in the SBFD time unit and the number of symbols of the downlink transmission resources in the non-SBFD time unit, as Substitute into formula (1), and take the average of the sum of the number of PRBs in the frequency domain resources where the downlink transmission resources overlap with the downlink subband corresponding to the SBFD time unit and the number of PRBs in the downlink transmission resources in the non-SBFD time unit, as n PRB Substitute into formula (2) to calculate the downlink TBS.

[0138] Optionally, the TBS can be determined in a third way, where the number of symbols of downlink transmission resources can be used as Substitute into formula (1), and take the average of the sum of the number of PRBs in the frequency domain resources where the downlink transmission resources overlap with the downlink subband corresponding to the SBFD time unit and the number of PRBs in the downlink transmission resources in the non-SBFD time unit, as n PRB Substitute into formula (2) to calculate the downlink TBS.

[0139] In the second case, the TB is transmitted in multiple time slots, that is, the transmission resources configured by the resource scheduling information support TBoMS.

[0140] In one implementation, the TBS is determined in a first manner, for example, according to any one of manners 1 to 4. The first manner may include: the terminal device determines the TBS based on the number of transmission resources in the SBFD time unit and first indication information. The first indication information is carried by resource scheduling information, and the first indication information is used to indicate the number of time slots occupied by the transport block. For example, the first indication information is the parameter numberOfSlotsTBoMS carried in the resource scheduling information.

[0141] For example, the number of symbols of uplink transmission resources in the SBFD time unit can be used as Substitute into formula (1), and take the number of PRBs in the frequency domain resources where the uplink transmission resource overlaps with the uplink subband corresponding to the SBFD time unit as nPRB And the number of time slots occupied by the transport block indicated by the first indication information is substituted as N into formula (4), thereby obtaining the uplink TBS.

[0142] In another implementation, the TBS is determined in a second manner, for example, according to any one of Methods 1 to 4. The second manner may include: the terminal device determining the TBS based on the number of transmission resources in the non-SBFD time unit and the first indication information. The details of the first indication information are described above and are not repeated here.

[0143] For example, the number of symbols of uplink transmission resources in non-SBFD time units can be used as Substitute into formula (1) and take the number of PRBs in the frequency domain resources corresponding to the uplink transmission resources in the non-SBFD time unit as n PRB And the number of time slots occupied by the transport block indicated by the first indication information is substituted as N into formula (4), thereby obtaining the uplink TBS.

[0144] In another implementation, the TBS is determined in a third manner. The terminal device can use the symbol number of the uplink transmission resource in the SBFD time unit as Substitute into formula (1), and take the number of PRBs in the frequency domain resources where the uplink transmission resource overlaps with the uplink subband corresponding to the SBFD time unit as n PRB Substitute into formula (2) to obtain the uplink TBS corresponding to the SBFD time unit; and the number of symbols that can transmit resources in the non-SBFD time unit is used as Substitute into formula (1) and take the number of PRBs of uplink transmission resources in the non-SBFD time unit as n PRB Substitute into formula (2) to calculate the uplink TBS corresponding to the non-SBFD time unit, and add the uplink TBS corresponding to the SBFD time unit and the uplink TBS corresponding to the non-SBFD time unit to obtain the uplink TBS.

[0145] Optionally, when a transmission includes multiple SBFD time units and multiple non-SBFD time units in the time domain, the TBS is determined in a third way. For each SBFD time unit, the number of symbols of the uplink transmission resource in the SBFD time unit can be used as Substitute into formula (1), and take the number of PRBs in the frequency domain resources where the uplink transmission resource overlaps with the uplink subband corresponding to the SBFD time unit as n PRBSubstitute into formula (2) to obtain the uplink TBS corresponding to the SBFD time unit; and for each non-SBFD time unit, the number of symbols of the transmission resource in the non-SBFD time unit can be used as Substitute into formula (1) and take the number of PRBs of uplink transmission resources in the non-SBFD time unit as n PRB Substitute into formula (2) to calculate the uplink TBS corresponding to the non-SBFD time unit. Furthermore, the uplink TBSs corresponding to the multiple SBFD time units are added to the uplink TBSs corresponding to the multiple non-SBFD time units to obtain the uplink TBS. For example, when the transmission resource includes two SBFD time units and three non-SBFD time units in the time domain, the uplink TBS corresponding to each SBFD time unit and the uplink TBS corresponding to each non-SBFD time unit can be calculated separately. The uplink TBSs corresponding to the five time units are then added to obtain a TBS applicable to TBoMS.

[0146] Optionally, the TBS can be determined in a third way by taking the sum of the number of symbols of the uplink transmission resource in the SBFD time unit and the number of symbols of the uplink transmission resource in the non-SBFD time unit as the TBS. Substitute into formula (1), and take the sum of the number of PRBs in the frequency domain resources where the uplink transmission resources overlap with the uplink subband corresponding to the SBFD time unit and the number of PRBs in the uplink transmission resources in the non-SBFD time unit as n PRB Substitute into formula (2) to calculate the uplink TBS.

[0147] Optionally, the TBS can be determined in a third way by taking the average of the sum of the number of symbols of the uplink transmission resources in the SBFD time unit and the number of symbols of the uplink transmission resources in the non-SBFD time unit, as Substitute into formula (1); take the average of the sum of the number of PRBs in the frequency domain resources where the uplink transmission resources overlap with the uplink subband corresponding to the SBFD time unit and the number of PRBs in the uplink transmission resources in the non-SBFD time unit as n PRB , and the number of time slots occupied by the transport block indicated by the first indication information is substituted as N into formula (4), thereby obtaining the uplink TBS.

[0148] In the embodiment of the present application shown in Figure 8, the terminal device receives resource scheduling information from the network device, which is conducive to determining the transmission block size based on the number of transmission resources in the sub-band full-duplex time unit and / or non-sub-band full-duplex time unit configured according to the resource scheduling information; wherein, the number of resources in the sub-band full-duplex time unit used to determine the transmission block size includes the number of frequency domain resources overlapping with the uplink transmission resource and the uplink sub-band, or the number of frequency domain resources overlapping with the downlink transmission resource and the downlink sub-band. The overlapping frequency domain resources are frequency domain resources that can be used for uplink or downlink, ensuring that the transmission block size can be effectively applied to the resource scheduling across sub-band full-duplex time units and non-sub-band full-duplex time units, thereby improving the communication quality of the sub-band full-duplex communication scenario.

[0149] Please refer to FIG9 , which is a flowchart of another TBS determination method provided in an embodiment of the present application. The method may include but is not limited to the following steps:

[0150] 901. The network device sends resource scheduling information to the terminal device. The resource scheduling information is used to configure uplink or downlink transmission resources. The transmission resources include SBFD time units in the time domain. Correspondingly, the terminal device receives the resource scheduling information from the network device.

[0151] Optionally, in the case of dynamic resource scheduling, resource scheduling information can be carried in the scheduling DCI. In the case of semi-static resource scheduling, resource scheduling information can be carried in higher-layer signaling, such as RRC signaling. Resource scheduling information can also be carried in corresponding control information or signaling according to other resource scheduling methods, which are not limited here.

[0152] Optionally, the uplink transmission resource may be a PUSCH, and the downlink transmission resource may be a PDSCH.

[0153] Optionally, the method may further include the following steps:

[0154] 902a, the terminal device determines the uplink TBS based on the number of frequency domain resources overlapping between the uplink transmission resources and the uplink subband corresponding to the SBFD time unit, or determines the downlink TBS based on the number of frequency domain resources overlapping between the downlink transmission resources and the downlink subband corresponding to the SBFD time unit.

[0155] The transmission resources configured by the resource scheduling information include SBFD time units in the time domain, which means that the network device performs resource scheduling in the SBFD time unit at that time, and the aforementioned situation 1 exists.

[0156] Optionally, the number of frequency domain resources in which uplink transmission resources overlap with the uplink subband corresponding to the SBFD time unit may refer to the number of frequency domain resources in which uplink transmission resources overlap with the uplink subband corresponding to one SBFD time unit. The number of frequency domain resources in which downlink transmission resources overlap with the downlink subband corresponding to the SBFD time unit may refer to the number of frequency domain resources in which downlink transmission resources overlap with the downlink subband corresponding to one SBFD time unit. The number of frequency domain resources refers to the number of PRBs.

[0157] In the case where the resource scheduling information configures the uplink transmission resources, the terminal device determines the uplink TBS based on the number of frequency domain resources overlapping the uplink transmission resources and the uplink subband corresponding to the SBFD time unit, that is, the uplink TBS is determined based on the number of frequency domain resources excluding the uplink subband and frequency domain guard band corresponding to the SBFD time unit in the uplink transmission resources. For example, the number of PRBs in the frequency domain resources overlapping the uplink transmission resources and the uplink subband corresponding to the SBFD time unit is taken as n PRB Substitute into formula (2) to obtain the uplink TBS.

[0158] Please refer to Figure 10, which is a schematic diagram of another network device scheduling PUSCH provided by an embodiment of the present application. As shown in Figure 10, the PUSCH configured by the network device for the terminal device overlaps with the downlink subband and frequency domain protection band corresponding to the SBFD time unit. In the resources corresponding to the non-SBFD time unit, D indicates that all frequency domain resources corresponding to the time unit can only be used for downlink transmission, and U indicates that all frequency domain resources corresponding to the time unit can only be used for uplink transmission. In the frequency domain resources corresponding to the SBFD time unit, D represents the downlink subband, and U represents the uplink subband. The frequency domain interval between the downlink subband and the uplink subband is the frequency domain protection band. The overlapped part of the PUSCH configured by the network device for the terminal device with the downlink subband and frequency domain protection band corresponding to the SBFD time unit is indicated by a blank bar marked with PUSCH, and the overlapped part of the PUSCH configured by the network device for the terminal device with the uplink subband corresponding to the SBFD time unit is indicated by a gray bar marked with PUSCH.

[0159] When the resource scheduling information configures the downlink transmission resources, the terminal device determines the downlink TBS based on the number of frequency domain resources overlapping between the downlink transmission resources and the downlink sub-band corresponding to the SBFD time unit, that is, the downlink TBS is determined based on the number of frequency domain resources in the uplink transmission resources excluding at least the uplink sub-band and frequency domain protection band corresponding to the SBFD time unit.

[0160] Please refer to Figure 11, which is a schematic diagram of another network device scheduling PDSCH provided by an embodiment of the present application. As shown in Figure 11, the PDSCH configured by the network device for the terminal device overlaps with the uplink subband and frequency domain protection band corresponding to the SBFD time unit. In the resources corresponding to the non-SBFD time unit, D indicates that all frequency domain resources corresponding to the time unit can only be used for downlink transmission, and U indicates that all frequency domain resources corresponding to the time unit can only be used for uplink transmission. In the frequency domain resources corresponding to the SBFD time unit, D represents the downlink subband, and U represents the uplink subband. The frequency domain interval between the downlink subband and the uplink subband is the frequency domain protection band. In slot 1 and slot 2, the PDSCH configured by the network device for the terminal device overlaps with the uplink subband and frequency domain protection band corresponding to the SBFD time unit, which is indicated by a blank bar marking PDSCH. The PDSCH configured by the network device for the terminal device overlaps with the downlink subband corresponding to the SBFD time unit, which is indicated by a gray bar marking PDSCH. In slot 3. The overlapping portion of the PDSCH configured by the network device for the terminal device with the uplink subband and frequency domain guard band corresponding to the SBFD time unit, and the overlapping portion with a downlink subband corresponding to the SBFD time unit are represented by a blank bar marked with PDSCH. The overlapping portion of the PDSCH configured by the network device for the terminal device with another downlink subband corresponding to the SBFD time unit is represented by a gray bar marked with PDSCH.

[0161] Optionally, the terminal device may determine the downlink TBS based on the number of frequency domain resources overlapping between the downlink transmission resources and the downlink subband corresponding to the SBFD time unit in the following two ways:

[0162] Method 1: The terminal device determines the downlink TBS based on the total number of frequency domain resources that overlap with the downlink subband corresponding to the SBFD time unit, that is, the downlink TBS is determined based on the number of resources in the downlink transmission resources excluding the uplink subband and frequency domain guard band corresponding to the SBFD time unit. For example, the number of PRBs of the total frequency domain resources that overlap with the downlink transmission resources and the downlink subband corresponding to the SBFD time unit is taken as n PRB Substitute into formula (2) to obtain the downlink TBS.

[0163] Method 2: The terminal device determines the downlink TBS based on the number of frequency domain resources that overlap with the downlink subband corresponding to the SBFD time unit, that is, the downlink transmission resource excludes the uplink subband, frequency domain guard band, and downlink subband corresponding to the SBFD time unit from the downlink transmission resource. For example, the number of PRBs of the frequency domain resources that overlap with the downlink subband corresponding to the SBFD time unit is taken as n PRBSubstitute into formula (2) to obtain the downlink TBS.

[0164] Among them, method one can be applicable to the case where the terminal device supports non-continuous downlink transmission across uplink sub-bands under SBFD resource configuration, and method two can be applicable to the case where the terminal device does not support non-continuous downlink transmission across uplink sub-bands under SBFD resource configuration. For method two, part of the frequency domain resources are determined according to the second configuration information, predefined information or the second default value. Optionally, the second configuration information or the second default value is sent by the network device to the terminal device, or is predefined on the terminal device. For example, the second configuration information can be configured, the predefined information can be defined, or the second default value can indicate: the downlink TBS is determined according to the frequency domain resources where the downlink sub-band with a higher or lower frequency domain position overlaps with the transmission resource.

[0165] As shown in Figure 11, slot 1 to slot 3 are SBFD time units; in the frequency domain resources corresponding to slot 1, the PDSCH configured by the network device overlaps with a downlink sub-band, and the terminal device can adopt method 1, that is, according to the number of frequency domain resources where the PDSCH configured by the network device overlaps with the downlink sub-band, the downlink TBS is determined; in the frequency domain resources corresponding to slot 2, the PDSCH configured by the network device overlaps with two downlink sub-bands across the uplink sub-band, and the terminal device can adopt method 1, that is, according to the number of frequency domain resources where the PDSCH configured by the network device overlaps with the two downlink sub-bands across the uplink sub-band, the downlink TBS is determined; in slot 3 In the frequency domain resources corresponding to the PDSCH configured by the network device, there is overlap with the two downlink subbands that span the uplink subband. The terminal device can adopt method 2, that is, it is determined according to the number of frequency domain resources that overlap with the PDSCH configured by the network device and one of the downlink subbands. The downlink subband is determined as the downlink subband with a higher frequency domain position in the two downlink subbands according to the second configuration information, predefined information or the second default value.

[0166] Optionally, after executing step 901, the method further includes:

[0167] 902b, the terminal device determines the TBS based on the resource quantity of the transmission resource.

[0168] The number of transmission resources includes the number of symbols in each time slot configured for uplink or downlink transmission, and the number of PRBs configured for uplink or downlink transmission. Substitute into formula (1) and use the number of PRBs as n PRB Substitute into formula (2) to obtain the uplink or downlink TBS.

[0169] It should be noted that either step 902a or step 902b can be performed.

[0170] In the embodiment of the present application shown in Figure 9, the terminal device receives resource scheduling information from the network device, which is conducive to determining the transmission block size based on the number of resources of the transmission resources configured according to the resource scheduling information in the sub-band full-duplex time unit; wherein, the uplink transmission block size is determined based on the number of frequency domain resources overlapping between the uplink transmission resources and the uplink sub-band corresponding to the sub-band full-duplex time unit, or the downlink transmission block size is determined based on the number of frequency domain resources overlapping between the downlink transmission resources and the downlink sub-band corresponding to the sub-band full-duplex time unit, ensuring that the transmission block size can be effectively applied to the resource scheduling situation of the sub-band full-duplex time unit, thereby improving the communication quality of the sub-band full-duplex communication scenario.
