[0025] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in detail below with reference to the drawings. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other as long as there is no conflict.

[0026] In order to improve the UL coverage of a Time Division Duplexing (TDD) system, reduce the latency of UL transmission, and increase the capacity of UL transmission, a sub-band full duplex (SBFD) technology is proposed for a Radio Resource Control (RRC) connected state User Equipment (UE).

[0027] In the related art, an UL sub-band can be configured in some or all of DL symbols or F symbols, but cannot be configured in UL symbols. For example, an UL sub-band is configured in a DL symbol, and at the same time, a DL sub-band is also configured in the DL symbol. That is, the UL sub-band and the DL sub-band (also referred to as an SBFD sub-band) are simultaneously configured in the DL symbol or the F symbol. The symbol configured with the SBFD sub-band is referred to as an SBFD symbol, and the symbol not configured with the SBFD sub-band is referred to as a non-SBFD symbol. However, the UL sub-band and the DL sub-band are prohibited from being configured in the UL symbol. In this case, the UL BWP is used for UL transmission in the UL symbol, and the UL sub-band is used for uplink transmission in the SBFD symbol. However, the interference in the UL BWP and the UL sub-band is different, and therefore the corresponding UL transmission is required to provide corresponding transmission parameters and configuration parameters to adapt to the UL transmission in the UL BWP and the UL sub-band, respectively. This will lead to the complexity of the design of the UL transmission in the system.

[0028] To further improve system efficiency, full duplex technology is studied, for example, in-band full duplex (IBFD) operation, that is, a time-frequency resource is configured in the carrier bandwidth of a carrier, and in the time-frequency resource, the base station can perform simultaneous transmission and reception at the same frequency. For example, consecutive resource blocks (RBs) are configured as IBFD subbands in the carrier bandwidth, and the IBFD subband is configured in all or part of the symbols, thereby forming an IBFD operation resource. However, in future systems, how to configure / update the above-mentioned SBFD subband and the configuration of the IBFD subband is provided below.

[0029] The UL subband and the DL subband are also referred to as SBFD subbands, that is, an SBFD subband is configured in the DL BWP in the DL symbol / slot, and the SBFD subband generally includes at least one DL subband and one UL subband.

[0030] For example, in a 100MHz TDD carrier, 20 consecutive RBs are configured as the UL subband in the DL BWP in the DL symbol / slot, and the remaining frequency domain resources of the DL BWP are the DL subband (the gap can not be configured), or a DL subband is also configured in the DL BWP in the DL symbol / slot. In this way, in the DL symbol / slot, the UL subband can be used for UL transmission, and the DL subband can be used for DL transmission. FIG. 1 provides a schematic diagram of an SBFD subband, which includes an UL subband and two DL subbands. This frequency domain pattern is generally referred to as “DUD” (based on frequency domain structure), wherein the horizontal axis represents the time domain direction, and the vertical axis represents the frequency domain direction. FIG. 2 provides a schematic diagram of another SBFD subband, which includes an UL subband and a DL subband, and the UL subband is located below the DL subband. This frequency domain pattern is generally referred to as “DU” (based on frequency domain structure), wherein the horizontal axis represents the time domain direction, and the vertical axis represents the frequency domain direction.

[0031] At the current stage, the subband full duplex technology includes the following features:

[0032] The base station has the capability to simultaneously perform reception (in the UL subband) and transmission (in the DL subband) in the same time domain. The UE does not have the capability to simultaneously perform reception (in the DL subband) and transmission (in the UL subband) in the same time domain. Here, the UL subband and the DL subband are configured in the same OFDM symbol / slot and are frequency-division.

[0033] For the convenience of description, some technical terms are as follows:

[0034] A symbol configured with SBFD subbands is referred to as a SBFD symbol. A slot containing SBFD symbols is referred to as a SBFD slot. A symbol not configured with SBFD subbands is referred to as a non-SBFD symbol (i.e., a regular symbol). A slot not containing SBFD symbols is referred to as a non-SBFD slot.

[0035] The SBFD subband operation described above is performed within a pair of DL BWP and UL BWP, and the pair of DL BWP and UL BWP is center frequency aligned.

[0036] FIG. 3a provides a schematic diagram of an IBFD subband, the whole carrier bandwidth of a carrier is configured with IBFD subbands, and the IBFD is configured in all symbols, wherein the horizontal axis represents the time domain direction, and the vertical axis represents the frequency domain direction; FIG. 3b provides a schematic diagram of another IBFD subband, part of the carrier bandwidth of a carrier is configured with IBFD subbands, and the IBFD is configured in part of the symbols. Wherein the horizontal axis represents the time domain direction, and the vertical axis represents the frequency domain direction.

[0037] A symbol configured with IBFD subbands is referred to as an IBFD symbol. A slot containing IBFD symbols is referred to as an IBFD slot. A symbol not configured with IBFD subbands is referred to as a non-IBFD symbol (i.e., a regular symbol). A slot not containing IBFD symbols is referred to as a non-IBFD slot.

[0038] The following scheme describes SBFD subbands, which is also used for IBFD subbands, only adaptive modification is needed, for example, replacing SBFD with IBFD.

[0039] The data transmission method provided by the embodiments of the present application can be executed by a communication node, which can be a base station, a user equipment, etc.

[0040] FIG. 4 is a flowchart of a data transmission method provided by an embodiment, as shown in FIG. 4, the method comprises S110-S120:

[0041] S110, in the case that the configuration mode is a first configuration mode and no data is actually transmitted in the first data transmission, determining the type of symbol associated with the transmission according to information associated with the data transmission.

[0042] The configuration mode can be understood as a mode describing in which type of symbol the data transmission is performed, and can be pre-configured; the first configuration mode is one of different configuration modes. The information associated with the transmission can be related resources of the transmission, configuration messages, etc.

[0043] The configuration mode of the communication node can be self-configured or configured by another communication node. In the case of the first configuration mode, it is determined whether data is actually transmitted in the first data transmission. The first data transmission can be predefined, for example, the first data transmission can be the first data transmission after the data transmission is activated, and the first data transmission can also be the first transmission opportunity in the data transmission process. If no data is actually transmitted, i.e., no actual data transmission occurs, the information associated with the data transmission is determined. The type of information associated with the data transmission can be pre-set, and the corresponding information can be directly obtained according to the set information type in the actual application process. Based on this part of information, the symbol type is determined. Different types of information can be used to determine the symbol type in different ways.

[0044] For example, in the case of a user equipment as a communication node, the user equipment can receive a configuration message, determine the configuration mode according to the configuration message, and determine the symbol type in the case of the first configuration mode and no actual data transmission in the first data transmission. The user equipment performs downlink reception according to the symbol type.

[0045] For example, in the case of a base station as a communication node, the base station can determine the configuration mode, and determine the symbol type in the case of the first configuration mode and no actual data transmission in the first data transmission. The base station performs uplink transmission according to the symbol type.

[0046] In the process of communication between different communication nodes, for example, in the process of communication between a base station and a user equipment, the configuration mode is usually configured. The embodiment of the present application can determine the symbol type in the case of the configuration mode being pre-configured.

[0047] S120, transmitting data according to the symbol type.

[0048] After the communication node determines the symbol type, it determines which type of symbol is used to transmit the data, and then transmits the data using the corresponding type of symbol when transmitting the data. The transmission can be at least one of uplink transmission and downlink transmission.

[0049] The data transmission method provided by the embodiment of the present application solves the problem that the symbol type cannot be determined in the case that no actual data transmission occurs in the first data transmission by determining the symbol type associated with the transmission according to the information associated with the transmission in the case that the configuration mode is the first configuration mode and no actual data transmission occurs in the first data transmission, and then transmitting the data according to the symbol type, thereby avoiding the case that the data cannot be normally transmitted. The embodiment of the present application provides a determination manner of the symbol type in the case that no actual data transmission occurs in the first data transmission, determines the symbol type associated with the transmission according to the information associated with the transmission, and improves the accuracy and effectiveness of data transmission.

[0098] The first configuration mode is that data transmission is only using SBFD symbols or data transmission is only using non-SBFD symbols; for example, data transmission is only using non-SBFD symbols in different slots, then all transmissions (including repeated transmissions, periodic transmissions) can only be in non-SBFD symbols.

[0099] The data transmission includes at least one of UL transmission and DL transmission, and the first configuration mode means that the UL transmission / DL transmission is limited to only in SBFD symbols or only in non-SBFD symbols in different slots. For example, the UL transmission / DL transmission is limited to only in SBFD symbols in different slots, then all transmissions (including repeated transmissions, periodic transmissions) of the UL transmission / DL transmission can only be in SBFD symbols.

[0103] For different data transmissions, the first transmission occasion can be different. Embodiments of the present application further provide the first transmission occasion in the case of different data transmissions.

[0104] In some embodiments, when the data transmission satisfies a first condition and there is no corresponding active downlink control information, the first transmission occasion is a first transmission occasion based on configuration relative to a system frame number equal to 0.

[0105] The first condition can be understood as a pre-set condition, which can be set according to the type of data transmission, downlink control information, etc. When the data transmission satisfies the first condition, it is determined whether the data transmission has corresponding active downlink control information.

[0118] In some embodiments, the first condition is that the data transmission is a periodic data transmission with N4 repetitions, and in the case that the data transmission satisfies the first condition and has corresponding activated downlink control information, the first repetition of the N repetitions corresponding to the first data transmission is determined based on the first transmission occasion configured to be equal to 0 relative to the system frame number.

[0119] In some embodiments, the first condition is that the data transmission is a periodic multi-slot data transmission across N5 transmissions without repetition, and in the case that the data transmission satisfies the first condition and has no corresponding activated downlink control information, the first transmission of the N5 transmissions corresponding to the first transmission occasion is determined based on the first transmission occasion configured to be equal to 0 relative to the system frame number.

[0121] In some embodiments, the first condition is that the data transmission is a periodic multi-slot data transmission across N6 transmissions with M2 repetitions, and in the case that the data transmission satisfies the first condition and has no corresponding activated downlink control information, the first transmission of the N6 transmissions corresponding to the first repetition of the M2 repetitions corresponding to the first transmission occasion is determined based on the first transmission occasion configured to be equal to 0 relative to the system frame number.

[0122] In some embodiments, the first condition is that the data transmission is a periodic multi-slot data transmission across N6 transmissions with M2 repetitions, and in the case that the data transmission satisfies the first condition and has corresponding activated downlink control information, the first transmission of the N6 transmissions corresponding to the first repetition of the M2 repetitions corresponding to the first data transmission is determined based on the first transmission occasion configured to be equal to 0 relative to the system frame number.

[0123] In some embodiments, determining the symbol type associated with the transmission according to the information associated with the data transmission comprises at least one of:

[0124] determining the symbol type associated based on the symbol type corresponding to the resources corresponding to the first transmission occasion;

[0125] determining the associated symbol type based on the symbol type corresponding to the resource corresponding to the first data transmission;

[0126] determining the associated symbol type based on the symbol type corresponding to the resource corresponding to the first actually occurring transmission occasion;

[0127] determining the associated symbol type based on the parameter of the configured grant configuration message.

[0128] For example, in the case that the configuration mode is the first configuration mode and no data is actually transmitted in the first data transmission, the symbol type corresponding to the resource corresponding to the first transmission occasion is determined as the associated symbol type, and data transmission is performed based on the symbol type.

[0129] For example, in the case that the configuration mode is the first configuration mode and no data is actually transmitted in the first data transmission, the symbol type corresponding to the resource corresponding to the first data transmission is determined as the associated symbol type, and data transmission is performed based on the symbol type.

[0130] For example, in the case that the configuration mode is the first configuration mode and no data is actually transmitted in the first data transmission, a first actually occurring transmission occasion is waited for, the symbol type corresponding to the resource corresponding to the first actually occurring transmission occasion is determined, the symbol type is determined as the associated symbol type, and data transmission is performed based on the symbol type.

[0131] For example, in the case that the configuration mode is the first configuration mode and no data is actually transmitted in the first data transmission, a configured grant configuration message is parsed, the message contains a parameter for indicating a symbol type, and the associated symbol type is determined based on the indication of the parameter.

[0132] The data transmission method provided by the embodiment of the present application provides multiple determination modes of symbol types, further refines the first data transmission, the first data transmission can be the first transmission occasion of data transmission, and the first transmission occasion corresponding to data transmission in different cases is explained, the first symbol type is quickly and effectively determined, data transmission is performed according to the symbol type, and the situation that data cannot be normally transmitted is avoided; the embodiment of the present application provides a determination mode of the symbol type in the case that no data is actually transmitted in the first data transmission, the symbol type associated with transmission is determined through information associated with transmission, and the accuracy and effectiveness of data transmission are improved.

[0133] FIG. 5 is a flowchart of a transmission block size determination method provided by an embodiment, as shown in FIG. 5, the method includes S210-S230:

[0134] S210, in a case where the configuration mode is the second configuration mode and the channel information satisfies the second condition, determining a quantity determination manner according to the channel information.

[0135] The second configuration mode is one of different configuration modes, and the second configuration mode can be different from the first configuration mode. The second condition can be understood as a condition for judging different types of channel information, and the second condition can be pre-set. The quantity determination manner can be understood as a manner adopted for determining the quantity of physical resource blocks (PRBs).

[0136] In a case where the configuration mode is the second configuration mode, the channel information is determined, and it is judged whether the channel information satisfies the second condition. If yes, the channel information is analyzed, and the quantity determination manner is determined according to the type of the channel information, the corresponding symbol type, the indication parameter, and the like. Different quantity determination manners can be pre-set, and one of the pre-set different quantity determination manners is selected as the final quantity determination manner used by analyzing the signal information.

[0137] For example, in a case where the communication node is a user equipment, the user equipment can receive a configuration message, determine the configuration mode according to the configuration message, and in a case where the configuration mode is the second configuration mode and the channel information satisfies the second condition, determine the quantity determination manner according to the channel information.

[0138] For example, in a case where the communication node is a base station, the base station can determine the configuration mode, and in a case where the configuration mode is the second configuration mode and the channel information satisfies the second condition, determine the quantity determination manner according to the channel information.

[0241] If the above-mentioned UL transmission is a HARQ-ACK PUCCH transmission (with repetition or without repetition) corresponding to a SPS PDSCH, the symbol type associated with the HARQ-ACK PUCCH transmission is determined based on the symbol type of the symbol where the first HARQ-ACK PUCCH repetition is located. If the HARQ-ACK PUCCH transmission is without repetition, the symbol type associated with the HARQ-ACK PUCCH transmission is determined based on the symbol type of the symbol where the HARQ-ACK PUCCH transmission is located.

[0242] If the semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) is configured to support delayed hybrid automatic repeat request-acknowledgement (HARQ-ACK), the symbol type associated with the HARQ-ACK PUCCH is determined based on the symbol type of the symbol where the first HARQ-ACK PUCCH repetition is located. If the first HARQ-ACK PUCCH repetition is delayed to be transmitted in another slot, the symbol type is still determined based on the symbol type of the symbol where the original first HARQ-ACK PUCCH repetition is originally scheduled to be located. Further, the delayed HARQ-ACK PUCCH can only be transmitted in the symbol corresponding to the symbol type that has been determined, that is, all repetitions of the HARQ-ACK PUCCH can only be transmitted in the symbol corresponding to the symbol type that has been determined.

[0243] If the SPS PDSCH is configured to support delayed HARQ-ACK, the symbol type of the associated HARQ-ACK PUCCH is determined based on the symbol type of the first HARQ-ACK PUCCH repetition actually transmitted. If the first HARQ-ACK PUCCH repetition is delayed to be transmitted in other slot, the symbol type is determined based on the symbol of the first HARQ-ACK PUCCH repetition actually transmitted after the delay. Further, the delayed HARQ-ACK PUCCH can determine a symbol type for the first HARQ-ACK PUCCH repetition among the two types of symbols, and the subsequent HARQ-ACK PUCCH repetitions use the determined symbol type.

[0244] If the HARQ-ACK PUCCH is not with repetition, the above processing of the first HARQ-ACK PUCCH repetition applies to the HARQ-ACK PUCCH without repetition.

[0245] The following is the explanation of the first occasion in different cases:

[0246] For a periodic data transmission (e.g., UL transmission and / or DL transmission) without corresponding activated DCI, the first occasion is determined based on the configured first occasion relative to SFN=0. For example, a periodic UL transmission or DL transmission is configured with a periodicity size and an offset relative to a predefined (or indicated) location, the first occasion is defined as the occasion corresponding to the offset. For example, according to TS 38.331, for a periodic type 1CG PUSCH without corresponding activated DCI, the parameter timeDomainOffset is used to configure the offset of the type 1CG PUSCH periodicity, e.g., the offset relative to a predefined location (indicated by timeReferenceSFN), so the first occasion for the type 1CG PUSCH is the occasion corresponding to the parameter timeDomainOffset.

[0247] For periodic data transmission (e.g., UL transmission and / or DL transmission) without repetition and with corresponding activation DCI, the first occasion refers to: the first occasion is determined based on the configured first occasion relative to SFN=0. For example, a periodic UL transmission or DL transmission is configured with a periodicity size and an offset relative to a predefined (or indicated) position, then the first occasion is defined as the occasion corresponding to the offset. Alternatively, the first occasion refers to the first UL transmission / DL transmission after the periodic UL transmission / DL transmission is activated by the activation DCI.

[0248] For periodic data transmission (e.g., UL transmission and / or DL transmission) with N repetitions and without corresponding activation DCI, the first occasion refers to: the first occasion is determined based on the configured first occasion relative to SFN=0. For example, a periodic UL transmission or DL transmission is configured with a periodicity size and an offset relative to a predefined (or indicated) position, then the first occasion is defined as the occasion corresponding to the offset. In particular, since the first occasion corresponds to the N repetitions of the UL transmission / DL transmission, the first occasion is the first repetition of the N repetitions corresponding to the first occasion.

[0249] For periodic data transmission (e.g., UL transmission and / or DL transmission) with N repetitions and with corresponding activation DCI, the first occasion refers to: the first occasion is determined based on the configured first occasion relative to SFN=0. For example, a periodic UL transmission or DL transmission is configured with a periodicity size and an offset relative to a predefined (or indicated) position, then the first occasion is defined as the occasion corresponding to the offset. In particular, since the first occasion corresponds to the N4 repetitions of the UL transmission / DL transmission, the first occasion is the first repetition of the N repetitions corresponding to the first occasion. Alternatively, the first occasion refers to the first UL transmission / DL transmission after the periodic UL transmission / DL transmission is activated by the activation DCI. In particular, since the first UL transmission / DL transmission corresponds to the N repetitions of the UL transmission / DL transmission, the first occasion is the first repetition of the N repetitions corresponding to the first UL transmission / DL transmission.

[0250] wherein, for a data transmission (e.g., UL transmission and / or DL transmission) with N repetitions, and aperiodic, and with corresponding DCI, the first occasion refers to: the first occasion refers to the first repetition of the N repetitions of the UL transmission / DL transmission.

[0251] wherein, for a multi-slot data transmission TBoMS across N transmissions without repetition, and periodic, and without corresponding activation DCI, the first occasion refers to: the first occasion is determined based on a configured first occasion relative to SFN=0. For example, a periodic UL transmission or DL transmission is configured with a periodicity size and an offset relative to a predefined (or indicated) position, then the first occasion is defined as the occasion corresponding to the offset. In particular, since the first occasion corresponds to the N transmissions of the TBoMS, the first occasion is the first transmission of the N transmissions corresponding to the first occasion.

[0252] wherein, for a TBoMS across N transmissions without repetition, and periodic, and with corresponding activation DCI, the first occasion refers to: the first occasion is determined based on a configured first occasion relative to SFN=0. For example, a periodic UL transmission or DL transmission is configured with a periodicity size and an offset relative to a predefined (or indicated) position, then the first occasion is defined as the occasion corresponding to the offset. In particular, since the first occasion corresponds to the N transmissions of the UL transmission / DL transmission, the first occasion is the first transmission of the N transmissions corresponding to the first occasion. Alternatively, the first occasion refers to the first UL transmission / DL transmission after the periodic UL transmission / DL transmission is activated by the activation DCI. In particular, since the first UL transmission / DL transmission corresponds to the N transmissions of the UL transmission / DL transmission, the first occasion is the first transmission of the N transmissions corresponding to the first UL transmission / DL transmission.

[0253] where, for a TBoMS with M repetitions across N transmissions (and aperiodic, assuming M=2, N=4, i.e., 1st repetition of 1st transmission, then 1st repetition of 2nd transmission, then 1st repetition of 3rd transmission, then 1st repetition of 4th transmission, then 2nd repetition of 1st transmission, then 2nd repetition of 2nd transmission, then 2nd repetition of 3rd transmission, then 2nd repetition of 4th transmission,...), and with corresponding DCI, the 1st occasion refers to: the 1st occasion refers to the 1st repetition of the M repetitions of the UL / DL transmission. Specifically, since the 1st repetition corresponds to the N transmissions of the UL / DL transmission, the 1st occasion is the 1st transmission of the N transmissions corresponding to the 1st repetition.

[0254] where, for a TBoMS with M repetitions across N transmissions (and aperiodic, i.e., 1st transmission is repeated M times, then 2nd transmission starts and is also repeated M times,...), and with corresponding DCI, the 1st occasion refers to: the 1st occasion refers to the 1st of the N transmissions. Specifically, since the 1st transmission corresponds to the M repetitions of the UL / DL transmission, the 1st occasion is the 1st repetition of the M repetitions corresponding to the 1st transmission.

[0255] where, for a TBoMS with M repetitions across N transmissions, and periodic, and without corresponding activating DCI, the 1st occasion refers to: the 1st occasion is determined based on a configured 1st occasion relative to SFN=0. For example, a periodic UL / DL transmission is configured with a periodicity size and an offset relative to a predefined (or indicated) position, then the 1st occasion is defined as the occasion corresponding to the offset. Specifically, since the 1st occasion corresponds to the M repetitions of the UL / DL transmission, and one repetition corresponds to N transmissions, the 1st occasion is the 1st transmission of the N transmissions corresponding to the 1st repetition of the 1st occasion.

[0256] For a TBoMS with M repetitions across N transmissions, and periodic, and with a corresponding activation DCI, the first occasion refers to: the first occasion is determined based on a configured first occasion relative to SFN=0. For example, a periodic UL transmission or DL transmission is configured with a periodicity size and an offset relative to a predefined (or indicated) position, then the first occasion is defined as the occasion corresponding to the offset. In particular, since the first occasion corresponds to the M repetitions of the UL transmission / DL transmission, and one repetition corresponds to N transmissions, the first occasion is the first transmission of the first repetition of the M repetitions corresponding to the first occasion. Alternatively, the first occasion refers to the first UL transmission / DL transmission after the periodic UL transmission / DL transmission is activated by the activation DCI. In particular, since the first UL transmission / DL transmission corresponds to the M repetitions of the UL transmission / DL transmission, and one repetition corresponds to N transmissions, the first occasion is the first transmission of the first repetition of the M repetitions corresponding to the first UL transmission / DL transmission.

[0257] For a single DCI scheduling N PDSCHs, the first occasion refers to: the first occasion is the first PDSCH of the N PDSCHs. Wherein the first PDSCH is determined based on the order of scheduling PDSCHs in the DCI, or the first PDSCH is determined based on the earliest PDSCH of the PDSCHs, if multiple PDSCHs have the same earliest starting symbol, then determine the PDSCH with more number of symbols from the multiple PDSCHs as the first PDSCH.

[0258] For example, a single DCI schedules 2 PDSCHs, denoted as PDSCH1 and PDSCH2, PDSCH1 is scheduled in symbol 3~symbol 8 of slot n, PDSCH2 is scheduled in symbol 3~symbol 8 of slot n+1. And according to the configuration of SBFD resource, symbol 3~symbol 8 of slot n is configured as SBFD symbol, symbol 3~symbol 8 of slot n+1 is not configured as SBFD symbol (i.e. non-SBFD symbol), so PDSCH1 is transmitted based on the related rules and requirements in SBFD symbol. PDSCH2 is transmitted based on the related rules and requirements in non-SBFD symbol.

[0259] The base station and the UE can agree that if the resource corresponding to the first occasion (or the first UL / DL transmission) contains SBFD symbols and non-SBFD symbols, the symbol type corresponding to the UL / DL transmission is determined based on the symbol type of the first symbol in the symbols corresponding to the first occasion (or the first UL / DL transmission).

[0260] The base station and the UE can agree that if the resource corresponding to the first occasion (or the first UL / DL transmission) of the UL transmission consists of DL non-SBFD symbols, the symbol type corresponding to the UL / DL transmission is non-SBFD symbol type.

[0261] The base station and the UE can agree that if the resource corresponding to the first occasion (or the first DL transmission) of the DL transmission consists of UL non-SBFD symbols, the symbol type corresponding to the DL reception is non-SBFD symbol type.

[0262] The base station and the UE can agree that for a type 1 CG PUSCH (i.e. periodic but without corresponding activation DCI), if the first configuration mode is provided for the type 1 CG PUSCH for the UE, the UE determines the symbol type associated with the type 1 CG PUSCH based on a new parameter 1 in the ConfiguredGrantConfig message. Specifically, the parameter 1 is used to indicate the symbol type associated with one type 1 CG PUSCH configured by the ConfiguredGrantConfig is SBFD symbol or non-SBFD symbol. The parameter 1 is applied to all type 1 CG PUSCHs configured by the ConfiguredGrantConfig. If the parameter 1 is not provided in the ConfiguredGrantConfig, the symbol type associated with the type 1 CG PUSCH is non-SBFD symbol (or SBFD symbol) by default. The ConfiguredGrantConfig message refers to TS 38.331.

[0263] The base station and the UE can agree that for a type 1 CG PUSCH (i.e. periodic but without corresponding activation DCI), if the first configuration mode is provided for the type 1 CG PUSCH for the UE, the UE determines the symbol type associated with the type 1 CG PUSCH based on a parameter 1 in the rrc-ConfiguredUplinkGrant message. Specifically, the parameter 1 is used to indicate the symbol type associated with one type 1 CG PUSCH configured by the ConfiguredGrantConfig is SBFD symbol or non-SBFD symbol. The parameter 1 is applied to type 1 CG PUSCHs configured by the rrc-ConfiguredGrantConfig. If the parameter 1 is not provided in the rrc-ConfiguredUplinkGrant, the symbol type associated with the type 1 CG PUSCH is non-SBFD symbol (or SBFD symbol) by default. The rrc-ConfiguredUplinkGrant message refers to TS 38.331.

[0264] The transport block size determination procedure is illustrated by the following embodiments:

[0265] Embodiment 2

[0266] The communication nodes are taken as examples of the base station and the UE respectively to illustrate the transport block size determination procedure.

[0267] If a DCI in a UE specific Search Space (USS) schedules a PDSCH in a single slot based on frequency domain resource allocation type 1, and the precoding resource block group (PRG) is determined to be one of {2, 4}, then the number of PRBs used to determine the TBS corresponding to the PDSCH is based on the number of PRBs among the PRBs allocated by the type 1 frequency domain resource allocation and located in the DL available PRBs. Where the DL available PRBs refer to the intersection PRBs of the DL subband in the SBFD symbol and the DL BWP in the frequency domain.

[0268] In related art, if a DCI schedules a PDSCH or PUSCH (without repetition or not TBoMS) in a single slot based on frequency domain resource allocation type 0, and one or more resource block groups (RBGs) allocated for the PDSCH or PUSCH have RBGs overlapping with the DL subband or UL subband boundary, then the number of PRBs used to determine the TBS corresponding to the PDSCH is based on the number of PRBs among the PRBs allocated by the type 0 frequency domain resource allocation and located in the DL available PRBs, or the number of PRBs used to determine the TBS corresponding to the PUSCH is based on the number of PRBs among the PRBs allocated by the type 0 frequency domain resource allocation and located in the UL available PRBs. Where the DL available PRBs refer to the intersection PRBs of the DL subband in the SBFD symbol and the DL BWP in the frequency domain, and the UL available PRBs refer to the intersection PRBs of the UL subband in the SBFD symbol and the UL BWP in the frequency domain. One RBG contains multiple PRBs.

[0269] For PDSCH / PUSCH (without repetition), the number of PRBs used to determine the TBS can be determined according to one of the following ways (hereinafter referred to as way 1 and way 2):

[0270] Number determination way 1: based on the number of PRBs allocated for the PDSCH / PUSCH;

[0271] Number determination way 2: based on the number of PRBs among the PRBs allocated for the PDSCH / PUSCH and located in the DL / UL available PRBs.

[0272] However, for a periodic PDSCH / PUSCH or PDSCH / PUSCH with repetition or PDSCH / PUSCH scheduled by single DCI, it can correspond to different time-frequency resources, so how to select a method (from method 1 and method 2) for determining the number of PRBs corresponding to the TBS of a PDSCH / PUSCH becomes a problem to be solved. Embodiments of the present application provide the following schemes.

[0273] The base station and the UE agree that if the data transmission (for example, DL transmission and / or UL transmission) is configured as the second configuration mode for the UE, the number of PRBs used to determine the TBS corresponding to the SPS PDSCH / CG PUSCH is determined based on the following method for an SPS PDSCH configuration without repetition or a CG PUSCH configuration without repetition. Note that it is assumed here that one occasion of an SPS PDSCH / CG PUSCH configuration transmits one SPS PDSCH / CG PUSCH without repetition, that is, one occasion corresponds to one SPS PDSCH / CG PUSCH without repetition. Some concepts can be explained with reference to Embodiment 1.

[0274] The specific method includes at least one of the following options:

[0275] Option 1:

[0276] The way of determining the number of PRBs for TBS determination for a SPS PDSCH / CG PUSCH occasion is based on the symbol type (SBFD symbol or non-SBFD symbol) of the symbol where the occasion is located. For example, for a SPS PDSCH / CG PUSCH (without repetition) configuration, the number of PRBs for TBS determination for a SPS PDSCH / CG PUSCH occasion is determined based on the symbol type of the symbol where the occasion is located. Thus, the way of determining the number of PRBs for TBS determination for a SPS PDSCH / CG PUSCH occasion can be different. For example, if a SPS PDSCH / CG PUSCH occasion is located in a SBFD symbol, the number of PRBs for TBS determination for the occasion is determined based on way 2; otherwise, the number of PRBs for TBS determination for the occasion is determined based on way 1. That is, the base station and the UE respectively determine the symbol type of the symbol where each SPS PDSCH / CG PUSCH occasion is located, and then respectively determine the way of determining the number of PRBs for TBS determination for each SPS PDSCH / CG PUSCH occasion from way 1 and way 2. The SPS PDSCH / CG PUSCH transmission (for the base station) or reception (for the UE) is performed based on the determined TBS in the occasion.

[0277] Option 1 can fully combine the characteristics of SBFD symbols and non-SBFD symbols to determine the best TBS and improve the transmission efficiency of each occasion.

[0278] Option 2:

[0279] The SPS PDSCH / CG PUSCH configuration's frequency domain resource determines the way of SPS PDSCH / CG PUSCH corresponding to all occasions of the SPS PDSCH / CG PUSCH configuration for determining the number of PRBs for TBS. For example, if the frequency domain resource of a SPS PDSCH / CG PUSCH configuration (i.e. the frequency domain resource corresponding to all occasions, which are the same) is in the DL / UL available PRBs (of SBFD symbols), the SPS PDSCH / CG PUSCH corresponding to all occasions of the SPS PDSCH / CG PUSCH configuration for determining the number of PRBs for TBS is determined based on way 1, that is, the way of SPS PDSCH / CG PUSCH corresponding to the SPS PDSCH / CG PUSCH configuration for determining the number of PRBs for TBS is uniformly based on way 1; otherwise, that is, if part or all of the frequency domain resource of the SPS PDSCH / CG PUSCH configuration is outside the DL available PRBs of SBFD symbols, the SPS PDSCH / CG PUSCH corresponding to all occasions of the SPS PDSCH / CG PUSCH configuration for determining the number of PRBs for TBS is determined based on way 2, that is, the way of SPS PDSCH / CG PUSCH corresponding to the SPS PDSCH / CG PUSCH configuration for determining the number of PRBs for TBS is uniformly based on way 2.

[0280] Option 2 is simple and can maintain uniform processing for all occasions.

[0281] Option 3:

[0282] The way of determining the number of PRBs for TBS determination for SPS PDSCH / CG PUSCH corresponding to all occasions of a SPS PDSCH / CG PUSCH configuration is determined based on the symbol type of the symbol corresponding to the time domain resource of the first occasion (or the first SPS PDSCH / CG PUSCH after activation) of the SPS PDSCH / CG PUSCH configuration. For example, if all time domain resources (i.e. the time domain resources corresponding to all occasions, which are the same) of a SPS PDSCH / CG PUSCH configuration are SBFD symbols, the way of determining the number of PRBs for TBS determination for SPS PDSCH / CG PUSCH corresponding to all occasions of the SPS PDSCH / CG PUSCH configuration is determined based on way 2, i.e. the way of determining the number of PRBs for TBS determination for SPS PDSCH / CG PUSCH corresponding to all occasions of the SPS PDSCH / CG PUSCH configuration is unified based on way 2; otherwise, i.e. if all time domain resources of the SPS PDSCH / CG PUSCH configuration are non-SBFD symbols, the way of determining the number of PRBs for TBS determination for SPS PDSCH / CG PUSCH corresponding to all occasions of the SPS PDSCH / CG PUSCH configuration is determined based on way 1, i.e. the way of determining the number of PRBs for TBS determination for SPS PDSCH / CG PUSCH corresponding to all occasions of the SPS PDSCH / CG PUSCH configuration is unified based on way 1. Wherein, the explanation of the first occasion here refers to the explanation of the first occasion in scheme 1.

[0283] Option 3 is simple and can keep all occasions with unified processing.

[0284] Option 4:

[0285] The SPS PDSCH configuration's frequency domain resource determines the way the SPS PDSCH corresponding to all occasions of the SPS PDSCH configuration is used to determine the number of PRBs for TBS. For example, if the SPS PDSCH configuration's frequency domain resource (i.e., the frequency domain resource corresponding to all occasions, which are the same) is across 2 DL subbands (of SBFD symbols), the SPS PDSCH corresponding to all occasions of the SPS PDSCH configuration is used to determine the number of PRBs for TBS is determined based on way 2, that is, the way the SPS PDSCH corresponding to all occasions of the SPS PDSCH configuration is used to determine the number of PRBs for TBS is uniformly based on way 2; otherwise, that is, if the SPS PDSCH configuration's frequency domain resource is not across 2 DL subbands (of SBFD symbols), the SPS PDSCH corresponding to all occasions of the SPS PDSCH configuration is used to determine the number of PRBs for TBS is determined based on way 1, that is, the way the SPS PDSCH corresponding to all occasions of the SPS PDSCH configuration is used to determine the number of PRBs for TBS is uniformly based on way 1.

[0286] Option 4 is simple and can keep all occasions have uniform processing.

[0287] Option 5:

[0288] The way of determining the number of PRBs for TBS determination for the SPS PDSCH / CG PUSCH corresponding to all occasions of the SPS PDSCH / CG PUSCH configuration is based on the periodicity size of the SPS PDSCH / CG PUSCH configuration. For example, if the periodicity of one SPS PDSCH / CG PUSCH configuration is larger than or equal to a threshold value, the way of determining the number of PRBs for TBS determination for the SPS PDSCH / CG PUSCH corresponding to all occasions of the SPS PDSCH / CG PUSCH configuration is determined based on way 1, that is, the way of determining the number of PRBs for TBS determination for the SPS PDSCH / CG PUSCH corresponding to all occasions of the SPS PDSCH / CG PUSCH configuration is unified based on way 1; otherwise, that is, if the periodicity of one SPS PDSCH / CG PUSCH configuration is smaller than the threshold value, the way of determining the number of PRBs for TBS determination for the SPS PDSCH / CG PUSCH corresponding to all occasions of the SPS PDSCH / CG PUSCH configuration is determined based on way 2, that is, the way of determining the number of PRBs for TBS determination for the SPS PDSCH / CG PUSCH corresponding to all occasions of the SPS PDSCH / CG PUSCH configuration is unified based on way 2. The threshold value can be predefined or signaled. For example, the threshold value is predefined as 2 slots or 3 slots or 4 slots.

[0289] Option 5 is simple and can keep all occasions with unified processing.

[0290] Option 6:

[0291] The type of frequency domain resource allocation of the SPS PDSCH / CG PUSCH configuration and / or the frequency domain resources of the SPS PDSCH / CG PUSCH configuration is used to determine the way the occasion(s) of the SPS PDSCH / CG PUSCH configuration correspond to SPS PDSCH / CG PUSCH for determining the number of PRBs for TBS. For example, for a SPS PDSCH / CG PUSCH configuration activated by DCI, and if the DCI allocates frequency domain resources for the SPS PDSCH / CG PUSCH based on frequency domain resource allocation Type 0, and part or all of the frequency domain resources (e.g., RBGs) of the occasion(s) of the SPS PDSCH / CG PUSCH configuration correspond to DL available PRBs outside of the SBFD symbols, then the SPS PDSCH / CG PUSCH of the occasion(s) corresponds to SPS PDSCH / CG PUSCH for determining the number of PRBs for TBS is determined based on way 2; otherwise, based on way 1.

[0292] Option 7:

[0293] The type of frequency domain resource allocation of the SPS PDSCH / CG PUSCH configuration and / or the frequency domain resources of the SPS PDSCH / CG PUSCH configuration and / or the PRG size is used to determine the way the occasion(s) of the SPS PDSCH / CG PUSCH configuration correspond to SPS PDSCH / CG PUSCH for determining the number of PRBs for TBS. For example, for a SPS PDSCH / CG PUSCH configuration activated by DCI, and if the DCI allocates frequency domain resources for the SPS PDSCH / CG PUSCH based on frequency domain resource allocation Type 1, and the PRG is 2 or 4, and part or all of the frequency domain resources of the occasion(s) of the SPS PDSCH / CG PUSCH configuration correspond to DL available PRBs outside of the SBFD symbols, then the SPS PDSCH / CG PUSCH of the occasion(s) corresponds to SPS PDSCH / CG PUSCH for determining the number of PRBs for TBS is determined based on way 2; otherwise, based on way 1.

[0294] Option 8:

[0295] ​Option 8: The way of determining the number of PRBs for determining TBS of a SPS PDSCH / CG PUSCH corresponding to an occasion of a SPS PDSCH / CG PUSCH configuration is determined based on a parameter in the activation DCI of the SPS PDSCH / CG PUSCH corresponding to the SPS PDSCH / CG PUSCH configuration. For example, the DAI field or the PRI field in the activation DCI can be re-interpreted to indicate the way of determining the number of PRBs for determining TBS of a SPS PDSCH / CG PUSCH corresponding to an occasion of a SPS PDSCH / CG PUSCH configuration from the way 1 and the way 2. The way of determining the number of PRBs for determining TBS of all occasions of the activated SPS PDSCH / CG PUSCH configuration is determined based on the way 1 or the way 2 directly indicated in the activation DCI. For example, if the parameter is not configured in the activation DCI, the way of determining the number of PRBs for determining TBS of a SPS PDSCH / CG PUSCH corresponding to an occasion of a SPS PDSCH / CG PUSCH configuration is based on the way 1 by default.

[0296] Option 9:

[0297] The way of determining the number of PRBs for determining TBS of a SPS PDSCH / CG PUSCH corresponding to an occasion of a SPS PDSCH / CG PUSCH configuration is determined based on a parameter in the RRC signaling corresponding to the SPS PDSCH / CG PUSCH configuration. For example, a parameter is added in the RRC signaling SPS-Config of the SPS PDSCH / CG PUSCH configuration to indicate the way of determining the number of PRBs for determining TBS of a SPS PDSCH / CG PUSCH corresponding to an occasion of a SPS PDSCH / CG PUSCH configuration from the way 1 and the way 2. After the SPS PDSCH / CG PUSCH is activated, the way of determining the number of PRBs for determining TBS of all occasions of the SPS PDSCH / CG PUSCH configuration is based on the way indicated by the parameter. For example, if the parameter is not configured in the RRC signaling SPS-Config, the way of determining the number of PRBs for determining TBS of a SPS PDSCH / CG PUSCH corresponding to an occasion of a SPS PDSCH / CG PUSCH configuration is based on the way 1 by default.

[0298] Option 8: The way of determining the number of PRBs for determining TBS of a SPS PDSCH / CG PUSCH corresponding to an occasion of a SPS PDSCH / CG PUSCH configuration is determined based on a parameter in the activation DCI of the SPS PDSCH / CG PUSCH corresponding to the SPS PDSCH / CG PUSCH configuration. For example, the DAI field or the PRI field in the activation DCI can be re-interpreted to indicate the way of determining the number of PRBs for determining TBS of a SPS PDSCH / CG PUSCH corresponding to an occasion of a SPS PDSCH / CG PUSCH configuration from the way 1 and the way 2. The way of determining the number of PRBs for determining TBS of all occasions of the activated SPS PDSCH / CG PUSCH configuration is determined based on the way 1 or the way 2 directly indicated in the activation DCI. For example, if the parameter is not configured in the activation DCI, the way of determining the number of PRBs for determining TBS of a SPS PDSCH / CG PUSCH corresponding to an occasion of a SPS PDSCH / CG PUSCH configuration is based on the way 1 by default.

[0299] The specific method includes at least one of the following options:

[0300] Option 10:

[0301] The TBS corresponding to a DL transmission / UL transmission is determined based on the proportion of different symbol types with N repetitions of the DL transmission / UL transmission. For example, for a PDSCH / PUSCH with N repetitions, if at least one repetition is in SBFD symbols / slots, the PRB number used to determine the TBS of the PDSCH / PUSCH is determined based on method 2, otherwise based on method 1. That is, for a PDSCH / PUSCH with N repetitions, if all N repetitions are in non-SBFD symbols / slots, the PRB number used to determine the TBS of the PDSCH / PUSCH is determined based on method 1, otherwise based on method 2. For example, for a PDSCH / PUSCH with N repetitions, if at least one repetition is in non-SBFD symbols / slots, the PRB number used to determine the TBS of the PDSCH / PUSCH is determined based on method 1, otherwise based on method 2. That is, for a PDSCH / PUSCH with N repetitions, if all N repetitions are in SBFD symbols / slots, the PRB number used to determine the TBS of the PDSCH / PUSCH is determined based on method 2, otherwise based on method 1. The determined PRB number used to determine the TBS of the DL transmission / UL transmission is applicable to all N repetitions of the DL transmission / UL transmission.

[0302] Note 1: For the same PDSCH / PUSCH frequency domain resource allocation, the number of available PRBs obtained in SBFD symbols / slots is always less than or equal to the number of available PRBs obtained in non-SBFD symbols / slots.

[0303] Note 2: If the TBS is determined based on method 2, in non-SBFD symbols, the information obtained by encoding modulation is transmitted based on one of the following: 1) only in the allocated PRBs which are the same as the available PRBs in SBFD symbols, 2) in all configured PRBs.

[0304] Option 11:

[0305] Determine the TBS of a data transmission based on the proportion of different symbol types that the data transmission with Q repetitions is in. For example, for a PDSCH / PUSCH with N repetitions, if at least X repetitions are in SBFD symbols / slots, the PRB number used to determine the TBS of the PDSCH / PUSCH is determined based on way 2, otherwise based on way 1. For example, for a PDSCH / PUSCH with N repetitions, if at least X repetitions are in non-SBFD symbols / slots, the PRB number used to determine the TBS of the PDSCH / PUSCH is determined based on way 1, otherwise based on way 2. Where X can be predefined, or X is determined based on N. Specifically including one of the following: X = N / 2, 1. The determined PRBs used to determine the TBS of the DL transmission / UL transmission apply to all N repetitions of the DL transmission / UL transmission.

[0306] The above-mentioned options 1-7 can also be adaptively modified and applied to the PDSCH / PUSCH with N repetitions. For example, replace the SPS PDSCH / CG PUSCH configuration occasion in options 1-7 with a repetition of the DL transmission / UL transmission. In this way, the operation in options 1-7 above for the occasion (including the first occasion, all occasions, each occasion) applies to the repetition of the DL transmission / UL transmission. For example, the above-mentioned options 2-4 are adaptively modified as follows, and other options are similar.

[0307] In order to support the DL transmission / UL transmission (such as PDSCH / PUSCH) with Q repetitions, the adaptively modified Option 2 is denoted as option 12:

[0308] The way of determining the number of PRBs for TBS determination for all repetitions of a data transmission is determined based on the frequency domain resource of the data transmission. For example, if the frequency domain resource of a DL transmission / UL transmission (i.e. the frequency domain resource of all repetitions, which are the same) is within the DL / UL available PRBs (of SBFD symbols), the way of determining the number of PRBs for TBS determination for all repetitions of the DL transmission / UL transmission is determined based on way 1, i.e. the way of determining the number of PRBs for TBS determination for PDSCH / PUSCH of the DL transmission / UL transmission is uniformly based on way 1; otherwise, i.e. if part or all of the frequency domain resource of the DL transmission / UL transmission is outside the DL / UL available PRBs (of SBFD symbols), the way of determining the number of PRBs for TBS determination for PDSCH / PUSCH of all repetitions of the DL transmission / UL transmission is determined based on way 2, i.e. the way of determining the number of PRBs for TBS determination for PDSCH / PUSCH of the DL transmission / UL transmission is uniformly based on way 2.

[0309] To support a data transmission (e.g. PDSCH / PUSCH) with N repetitions, the adaptively modified Option 3 is denoted as option 13:

[0310] The way of determining the number of PRBs for TBS determination for all repetitions of a data transmission is determined based on the symbol type of the symbol corresponding to the time domain resource of the first repetition of the data transmission. For example, if the time domain resource of a DL transmission / UL transmission with N repetitions are all SBFD symbols, the way of determining the number of PRBs for TBS determination for PDSCH / PUSCH of all repetitions of the DL transmission / UL transmission is determined based on way 2, i.e. the way of determining the number of PRBs for TBS determination for PDSCH / PUSCH of the DL transmission / UL transmission is uniformly based on way 2; otherwise, i.e. if the time domain resource of the DL transmission / UL transmission is not all within non-SBFD symbols, the way of determining the number of PRBs for TBS determination for PDSCH / PUSCH of all repetitions of the DL transmission / UL transmission is determined based on way 1, i.e. the way of determining the number of PRBs for TBS determination for PDSCH / PUSCH of the DL transmission / UL transmission is uniformly based on way 1. Wherein, the explanation of the first occasion here refers to the explanation of the first occasion in scheme 1.

[0311] To support a data transmission (e.g. PDSCH / PUSCH) with N repetitions, the adaptively modified Option 4 is denoted as option 14:

[0312] The way of determining the number of PRBs for determining TBS for all repetitions of a data transmission is determined based on the frequency domain resource of the data transmission. For example, if the frequency domain resource of a DL transmission / UL transmission is across 2 DL / UL subbands (of SBFD symbols), the way of determining the number of PRBs for determining TBS for PDSCH / PUSCH corresponding to all repetitions of the DL transmission / UL transmission is determined based on way 2, i.e. the way of determining the number of PRBs for determining TBS for PDSCH / PUSCH of the DL transmission / UL transmission is uniformly based on way 2; otherwise, i.e. if the frequency domain resource of the DL transmission / UL transmission is not across 2 DL / UL subbands (of SBFD symbols), the way of determining the number of PRBs for determining TBS for PDSCH / PUSCH corresponding to all repetitions of the DL transmission / UL transmission is determined based on way 1, i.e. the way of determining the number of PRBs for determining TBS for PDSCH / PUSCH of the DL transmission / UL transmission is uniformly based on way 1.

[0313] The base station and the UE agree that, if a data transmission is configured to the UE in the second configuration mode, the number of PRBs for determining TBS for PDSCH / CG PUSCH corresponding to the SPS PDSCH / CG PUSCH is determined based on the following method for one SPS PDSCH / CG PUSCH configuration with repetition. Note that some explanations of concepts can refer to Embodiment 1.

[0314] The specific method includes at least one of the following options:

[0315] The above described options 1-9 for SPS PDSCH / CG PUSCH without repetition can be reused. The difference is that one occasion of SPS PDSCH / CG PUSCH configuration with N times of repetition corresponds to N times of PDSCH / PUSCH repetition, while one occasion of SPS PDSCH / CG PUSCH configuration without repetition corresponds to 1 time of PDSCH / PUSCH repetition.

[0316] Alternatively, the above described options 10-14 for data transmission with N times of repetition can be reused, but with the following adaptive modification: N times of repetition of a data transmission corresponds to N times of repetition in one occasion of SPS PDSCH / CG PUSCH with N times of repetition. That is, for SPS PDSCH / CG PUSCH with N times of repetition, N times of repetition of one occasion is regarded as N times of repetition of a data transmission, so that the above described options 10-14 are adopted to ensure that the number of PRBs for determining TBS for SPS PDSCH / CG PUSCH corresponding to the occasion.

[0317] The base station and the UE agree that if data transmission is configured to the UE as the second configuration mode, the number of PRBs used for determining the TBS for the N PDSCHs / PUSCHs scheduled by a single DCI is determined based on the following methods. Note: Some explanations of the concepts can refer to Embodiment 1.

[0318] The specific method includes at least one of the following options:

[0319] Option 15:

[0320] The way each PDSCH / PUSCH is used to determine the number of PRBs for determining the TBS is determined based on the symbol type of the symbols corresponding to the resource of each PDSCH / PUSCH, respectively. For example, if the symbol type of the symbols corresponding to the resource of one of the N PDSCHs / PUSCHs is SBFD symbol, the way the PDSCH / PUSCH is used to determine the number of PRBs for determining the TBS is based on way 2. If the symbol type of the symbols corresponding to the resource of another of the N PDSCHs / PUSCHs is non-SBFD symbol, the way the PDSCH / PUSCH is used to determine the number of PRBs for determining the TBS is based on way 1. In this way, the way the N PDSCHs / PUSCHs are used to determine the number of PRBs for determining the TBS can be different.

[0321] Option 16:

For example, if the frequency domain resource of one of the N PDSCHs / PUSCHs is across 2 DL subbands (of SBFD symbols) (or not all in the DL available PRBs), the way the PDSCH / PUSCH is used to determine the number of PRBs for determining the TBS is determined based on way 2; otherwise, i.e., if the frequency domain resource of one of the N PDSCHs / PUSCHs is not across 2 DL subbands (of SBFD symbols) (or all in the DL available PRBs), the way the PDSCH / PUSCH is used to determine the number of PRBs for determining the TBS is determined based on way 1.

[0323] Option 17:

[0324] The manner in which the N PDSCHs / PUSCHs are used to determine the number of PRBs for determining the TBS is determined based on the type of frequency domain resource allocation of the N PDSCHs / PUSCHs and / or the frequency domain resources of the N PDSCHs / PUSCHs. For example, for N PDSCHs / PUSCHs scheduled by a single DCI, and if the DCI allocates frequency domain resources for the N PDSCHs / PUSCHs based on frequency domain resource allocation Type 0, and part or all of the frequency domain resources (e.g., RBGs) of one of the N PDSCHs / PUSCHs is outside the DL available PRBs in the SBFD symbol / slot, the number of PRBs for determining the TBS for the PDSCH / PUSCH is determined based on manner 2; otherwise, based on manner 1.

[0325] Option 18:

[0326] The manner in which the N PDSCHs / PUSCHs are used to determine the number of PRBs for determining the TBS is determined based on the type of frequency domain resource allocation of the N PDSCHs / PUSCHs and / or the frequency domain resources of the N PDSCHs / PUSCHs and / or the PRG size. For example, for N PDSCHs / PUSCHs scheduled by a single DCI, and if the DCI allocates frequency domain resources for the N PDSCHs / PUSCHs based on frequency domain resource allocation Type 1, and the PRG is 2 or 4, and part or all of the frequency domain resources corresponding to one of the N PDSCHs / PUSCHs is outside the DL available PRBs in the SBFD symbol / slot, the number of PRBs for determining the TBS for the PDSCH / PUSCH is determined based on manner 2; otherwise, based on manner 1.
