[0002] In order to improve the uplink (UL) coverage of a Time Division Duplexing (TDD) system, reduce the latency of UL transmission, and increase the capacity of UL transmission, a Subband Full Duplex (SBFD) technology has emerged.

[0033] In order to improve the UL coverage of the TDD system, reduce the delay of the UL transmission, and increase the capacity of the UL transmission, a SBFD technology for a radio resource control (RRC) connected state user equipment (UE) is developed.

[0034] For the SBFD technology, the UL sub-band can be configured in part or all of the DL symbol or F (flexible) symbol, but cannot be configured in the UL symbol. For example, an UL sub-band is configured in a DL symbol, and 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 the SBFD sub-band) are simultaneously configured in the DL symbol or the F symbol, but the UL sub-band and the DL sub-band are prohibited from being configured in the UL symbol. In this case, the uplink bandwidth part (UL BWP) in the UL symbol is used for UL transmission, and the UL sub-band in the SBFD symbol is used for uplink transmission, but the interference conditions in the UL BWP and the UL sub-band are different.

[0035] The UL sub-band and the DL sub-band are also referred to as the SBFD sub-band, that is, one SBFD sub-band is configured in the DL symbol / slot of the DL BWP, and the SBFD sub-band generally includes at least one DL sub-band and one UL sub-band.

[0036] For example, in a 100 MHz TDD carrier, 20 contiguous RBs are configured as the UL sub-band in the DL symbol / slot of the DL BWP, and the remaining frequency domain resources of the DL BWP are the DL sub-band (a gap can not be configured), or a DL sub-band is also configured in the DL symbol / slot of the DL BWP. In this way, in the DL symbol / slot, the UL sub-band can be used for UL transmission, and the DL sub-band can be used for DL transmission. FIG. 1 is a structure diagram of an SBFD sub-band provided by an embodiment of the present application, as shown in FIG. 1, one SBFD sub-band includes one UL sub-band and one DL sub-band, and this frequency domain pattern is generally referred to as “DUD” (based on a frequency domain structure). FIG. 2 is a structure diagram of another SBFD sub-band provided by an embodiment of the present application, as shown in FIG. 2, one SBFD sub-band includes one UL sub-band and one DL sub-band, and the UL sub-band is located below the DL sub-band, and this frequency domain pattern is generally referred to as “DU” (based on a frequency domain structure).

[0037] The SBFD technology has the following characteristics: the base station has the capability to perform reception in the UL subband and transmission in the DL subband in the same time domain at the same time. The UE does not have the capability to perform reception in the UL subband and transmission in the DL subband in the same time domain at the same time. Here, the UL subband and the DL subband are configured in the same OFDM symbol / slot and are frequency-division.

[0038] The SBFD subband operation described above is performed in a DL BWP and UL BWP pair, and the DL BWP and UL BWP pair are center frequency aligned.

[0039] In the embodiments of the present application, a symbol configured with a SBFD subband is referred to as a SBFD symbol, a slot containing a SBFD symbol is referred to as a SBFD slot, a symbol not configured with a SBFD subband is referred to as a non-SBFD symbol, and a slot not containing a SBFD symbol is referred to as a non-SBFD slot.

[0040] To further improve system efficiency, in-band full duplex (IBFD) technology is studied. The IBFD technology refers to configuring a time-frequency resource in the carrier bandwidth of a carrier, and in the time-frequency resource, the base station can perform simultaneous same-frequency transmission and reception. For example, consecutive RBs in the carrier bandwidth are configured as IBFD subbands, and the IBFD subbands are configured in all or part of the symbols, thereby forming an IBFD operation resource. FIG. 3 is a structure diagram of an IBFD subband provided by an embodiment of the present application. As shown in FIG. 3, part or all of the carrier bandwidth of a carrier is configured as an IBFD subband, and the IBFD subband is configured in all or part of the symbols.

[0041] In the embodiments of the present application, a symbol configured with an IBFD subband is referred to as an IBFD symbol, a slot containing an IBFD symbol is referred to as an IBFD slot, a symbol not configured with an IBFD subband is referred to as a non-IBFD symbol (that is, a regular symbol), and a slot not containing an IBFD symbol is referred to as a non-IBFD slot.

[0042] In the embodiments of the present application, the SBFD subband can be understood to include a DL subband, a UL subband, and a frequency domain gap. In addition, the SBFD subband can also be directly replaced by a UL subband or a DL subband. For example, the time domain and frequency domain resources configured for a SBFD subband can also be replaced by the time domain and frequency domain resources configured for a UL subband, or the time domain and frequency domain resources configured for a DL subband.

[0043] The following related methods are described based on SBFD subbands, but these methods can also be applied to IBFD subbands, for example, only need to replace the SBFD symbol / slot in these methods with IBFD symbol / slot, and replace non-SBFD symbol / slot with non-IBFD symbol / slot.

[0044] In the embodiments of the present application, two modes are provided for a transmission, as follows:

[0045] Mode 1: refers to a transmission being provided with cross-slot transmission, and only allows transmission in SBFD symbols in SBFD slots or in non-SBFD symbols in non-SBFD slots. For example, a transmission is only limited in SBFD symbols in SBFD slots, and all transmissions (including repeated transmissions, periodic transmissions) of the transmission can only be in SBFD symbols in SBFD slots. For example, a transmission is only limited in non-SBFD symbols in non-SBFD slots, and all transmissions (including repeated transmissions, periodic transmissions) of the transmission can only be in non-SBFD symbols in non-SBFD slots.

[0046] Mode 2: refers to a transmission being provided with cross-slot transmission, and allows transmission in SBFD symbols in SBFD slots and in non-SBFD symbols in non-SBFD slots. For example, a transmission (including periodic transmission, repeated transmission) of a transmission is in SBFD symbols in slot n, and another transmission of the transmission is in non-SBFD symbols in slot m.

[0047] The above transmission includes downlink (Downlink, DL) transmission, uplink (Uplink, UL) transmission.

[0048] The above DL transmissions include, but are not limited to, at least one of: a downlink physical shared channel (PDSCH) without repetition scheduled by a downlink control information (DCI), a PDSCH with repetition scheduled by a DCI, a periodic PDSCH without repetition (e.g., a semi-persistent scheduling Physical Downlink Shared Channel (SPS PDSCH)), a periodic PDSCH with repetition, multiple PDSCHs (without repetition) scheduled by a single DCI, multiple PDSCHs (with repetition) scheduled by a single DCI, a channel state information reference signal (CSI RS), a downlink positioning reference signal (DL PRS).

[0049] The above UL transmissions include, but are not limited to, at least one of: a physical uplink shared channel (PUSCH) without repetition scheduled by a DCI (further including a SP CSI PUSCH (semi-persistent channel state information PUSCH) in addition), a PUSCH with repetition scheduled by a DCI (further including a SP CSI PUSCH in addition), a periodic PUSCH without repetition (e.g., a type 2 CG PUSCH (configured grant type 2), a type 1 CG PUSCH (configured grant type 1), a SP CSI PUSCH, etc.), a periodic PUSCH with repetition (e.g., a type 2 CG PUSCH, a type 1 CG PUSCH, a SP CSI PUSCH, etc.), a TBoMS (transmission of multiple slots of data, with or without repetition), a PUCCH without repetition (including a P / SP CSI PUCCH, a SR PUCCH (scheduling request PUCCH), a HARQ-ACK PUCCH (hybrid automatic repeat request acknowledgement PUCCH)), a PUCCH with repetition (including a CSI PUCCH, a SR PUCCH, a HARQ-ACK PUCCH), a SRS.

[0050] TBoMS refers to a TB being transmitted across multiple slots, that is, the data corresponding to one TB is divided into n parts and transmitted in n slots.

[0051] Then, if the UL transmission is configured as mode 2, the corresponding resources in the SBFD symbol and the non-SBFD symbol need to be determined for the UL transmission respectively. To this end, the resources allocated to the UL transmission in the SBFD symbol and the non-SBFD symbol can be determined according to the method provided in the following embodiments.

[0052] FIG. 4 is a flowchart of a resource determination method provided in an embodiment of the present application. As shown in FIG. 4, the method comprises:

[0053] S401, in response to mode 2 being provided as the UL transmission and the resources of the UL transmission in the non-SBFD symbol being provided, determining the resources allocated to the UL transmission in the SBFD symbol according to the resources allocated to the UL transmission in the non-SBFD symbol and the configuration information of the UL subband in the SBFD symbol.

[0054] The resources allocated to the UL transmission in the non-SBFD symbol can be determined based on the frequency domain resource allocation field (FDRA) in the DCI or in the RRC, and the resources of the UL transmission in the SBFD symbol are determined based on the resources in the non-SBFD symbol and the configuration information of the UL subband in the SBFD symbol. The configuration information of the UL subband in the SBFD symbol can include at least one of the following: the index of the lowest PRB in the UL available PRBs (or in the UL subband) in the SBFD symbol, the total number of PRBs of the UL available PRBs (or in the UL subband) in the SBFD symbol, and the index of the highest PRB in the UL available PRBs (or in the UL subband) in the SBFD symbol.

[0055] For ease of description, relevant parameters can be explained: PRB nonSBFDstarting represents the index of the lowest PRB in the allocated PRBs in the non-SBFD symbol; N represents the number of allocated PRBs in the non-SBFD symbol; S ULsubband represents the index of the lowest PRB in the UL available PRBs in the SBFD symbol; N ULsubband represents the total number of PRBs of the UL available PRBs in the SBFD symbol; E ULsubband represents the index of the highest PRB in the UL available PRBs in the SBFD symbol; Offset represents the offset between the index of the lowest PRB allocated in the SBFD symbol and the index of the lowest PRB allocated in the non-SBFD symbol; N ULBWP represents the number of PRBs corresponding to the bandwidth of the UL BWP in the non-SBFD symbol; PRBSBFDstarting This indicates the index of the lowest PRB assigned to the UL transmission in the SBFD symbol.

[0056] N ULsubband The parameter S can be replaced by the difference between the largest and smallest indices of the UL-available PRBs (or UL sub-bands) plus 1. In other words, there is a correlation between the number of PRBs in the UL-available PRBs (or UL sub-bands) and the index of the largest PRB. Therefore, an equivalent substitution can be set based on this correlation. This substitution principle also applies to other related parameters. If the index of the lowest PRB in the UL-available PRBs (or UL sub-bands) within the SBFD symbol is 0, the above parameter S... ULsubband It's also possible that it's not needed.

[0057] The aforementioned UL available PRBs refer to the PRBs that intersect the UL subband and UL BWP in the frequency domain within the SBFD symbol.

[0058] Optionally, the same PRBs have the same index in the UL available PRBs (or PRBs in the UL sub-band) within the SBFD symbol and in the UL BWP within the non-SBFD symbol. That is, the PRBs in the UL available PRBs (or UL sub-band) within the SBFD symbol use the index of the corresponding PRB in the UL BWP.

[0059] Optionally, the UL transmission is assigned the same number of PRBs in both the SBFD symbol and the non-SBFD symbol.

[0060] Optionally, determining the resources allocated to the UL transmission in the SBFD symbol based on the resources allocated to the UL transmission in the non-SBFD symbol and the configuration information of the UL subband in the SBFD symbol may include one of the following methods:

[0061] Method 1: According to PRB nonSBFDstarting S ULsubband N ULsubband E ULsubband Determine the PRB by at least one of the following: and offset. SBFDstarting .

[0062] In some alternative implementations, PRB can be utilized. nonSBFDstarting The summation of N and offset ULsubband Perform the modulo operation, and then perform the modulo operation based on the result and S. ULsubband Determine PRB SBFDstarting .

[0063] Method 2: Based on PRB nonSBFDstarting , N, S ULsubband N ULsubbandat least one of the PRB SBFDstarting .

[0064] In some optional implementations, N ULsubband is subtracted from the target number of PRBs to obtain a remaining number of PRBs; and the PRB nonSBFDstarting is determined according to a modulo operation result of the remaining number of PRBs and S ULsubband . SBFDstarting ; wherein the target number is less than or equal to N.

[0065] Method three: the PRB nonSBFDstarting is determined according to at least one of N ULBWP , S ULsubband and N ULsubband . SBFDstarting .

[0066] In some optional implementations, the PRB nonSBFDstarting is determined according to a multiplication result of a first ratio and the PRB ULsubband , and S SBFDstarting ; wherein the first ratio is a ratio between N ULsubband and N ULBWP .

[0067] Optionally, the offset is default or 0. Optionally, if the offset is used, the offset is predefined or configured by signaling.

[0068] Optionally, in a case where the resource allocated to the UL transmission in the SBFD symbol based on the above method exceeds the range of the UL available PRBs in the SBFD symbol, the obtained PRB SBFDstarting is adjusted. The specific adjustment method can be: reducing the PRB SBFDstarting until there are or more than N consecutive PRBs from the reduced PRB SBFDstarting to E ULsubband , and determining the reduced PRB SBFDstarting as the target PRB SBFDstarting allocated to the UL transmission in the SBFD symbol, wherein the target PRB SBFDstarting is determined based on E ULsubband and N.

[0069] Next, the process of determining the resource allocated to the UL transmission in the SBFD symbol is specifically introduced as follows:

[0070] For convenience of description, the following assumptions are made to facilitate subsequent examples.

[0071] Assumption 1: The number of PRBs of the UL available PRBs (or UL subband) in the SBFD symbol is 50, and the index is from 10-59 (here it is assumed that the minimum PRB index of the UL available PRBs or UL subband is non-zero value). The number of PRBs corresponding to the UL BWP in the non-SBFD symbol is 200, and the index is from 0-199. The base station allocates 40 contiguous PRBs for the UL transmission in the non-SBFD symbol, and the corresponding index is 139-178.

[0072] Mode 1

[0073] If mode 2 is provided for the UL transmission, and one frequency domain resource allocation parameter is used to provide the resource (i.e. PRB, it is assumed that the index of the lowest PRB of the PRBs allocated for the UL transmission in the non-SBFD symbol is PRB nonSBFDstarting , and N contiguous PRBs are allocated), then the resource allocated for the UL transmission in the SBFD symbol can be determined by at least one of the following parameters: PRB nonSBFDstarting , N, S ULsubband , N ULsubband , E ULsubband , offset. Optionally, the same number of PRBs is allocated for the UL transmission in the SBFD symbol and the non-SBFD symbol.

[0074] Optionally, the frequency domain resource allocated for the UL transmission in the UL available PRBs of the SBFD symbol can be determined by the following equation 1: PRB SBFDstarting = S ULsubband + (PRB nonSBFDstarting +offset) mod N ULsubband Equation 1

[0075] mod represents the modulo operation, for example, a mod b = c, which means that the remainder of a divided by b is c.

[0076] After obtaining PRB SBFDstarting , in the UL available PRBs of the SBFD symbol, the contiguous N PRBs starting from (including) the PRB with index PRB SBFDstarting are determined as the PRBs allocated for the UL transmission in the UL available PRBs of the SBFD symbol.

[0077] offset is optional, if offset is used, the value of offset can be predefined or configured by signaling.

[0078] If the starting PRB index of the UL available PRBs (or UL subbands) in the SBFD symbol is 0, the above S ULsubband may not be needed. Also, in the UL available PRBs (or PRBs in the UL subbands) in the SBFD symbol and in the PRBs of the UL BWP in the non-SBFD symbol, the same PRB has the same index. That is, the PRB in the UL available PRBs (or UL subbands) keeps the index of the corresponding PRB in the UL BWP.

[0079] However, based on the above Equation 1, the PRBs allocated for the UL transmission in the SBFD symbol can exceed the range of the UL available PRBs. For example, based on the above assumption 1, the indices of the PRBs determined in the SBFD symbol by Equation 1 (assuming offset does not exist) are: 49-88. The specific process is: PRB SBFDstarting = 10 + 139 mod 50 = 49, then, the next 40 PRBs are allocated, so the indices of the PRBs allocated in the SBFD symbol are: 49-88, while the range of the indices of the UL available PRBs in the SBFD symbol is 10-59. Therefore, if the PRBs allocated for the UL transmission in the non-SBFD symbol by the base station are not appropriate, the PRBs determined in the UL available PRBs of the SBFD symbol based on Equation 1 are also not appropriate. Therefore, if Equation 1 is used, the UE expects that all the PRBs obtained based on Equation 1 are within the UL available PRBs (or UL subbands) of the SBFD symbol. That is, the base station needs to ensure that all the PRBs obtained based on Equation 1 are within the UL available PRBs (or UL subbands) of the SBFD symbol, thereby introducing additional restrictions on the resource allocation of the base station.

[0080] To address this situation, Equation 1 can be further improved, and the idea of the improvement is: reducing the PRB SBFDstarting until the reduced PRB SBFDstarting satisfies that there are or exceed N consecutive PRBs from the reduced PRB ULsubband to E SBFDstarting , the reduced PRB SBFDstarting is determined as the target PRB SBFDstarting allocated for the UL transmission in the SBFD symbol. ULsubband wherein the target PRB SBFDstarting is determined based on E SBFDstarting and N.

[0081] may first be determined based on Equation 1, if (PRB ULsubband +N-1) > E SBFDstarting , then adjust the PRB SBFDstarting according to the following adjustment mode 1: PRB SBFDstarting-(PRB SBFDstarting +N-1-E ULsubband )=E ULsubband -N+1.

[0082] If (PRB SBFDstarting +N-1)≤E ULsubband , no adjustment is made to PRB SBFDstarting (still based on equation 1 to determine PRB SBFDstarting ).

[0083] If there is no "1" in the above inequality or equation, it will make it difficult to allocate the maximum index PRB in the UL available PRBs. "1" can also be default, i.e. not exist, i.e. it is not needed. "1" can also be replaced by other constants. Or, if PRB SBFDstarting corresponding PRB is not included in the continuous N PRBs, i.e. if the allocated continuous N PRBs start from the PRB SBFDstarting +1 corresponding PRB, "1" can also not be needed.

[0084] The adjustment process is determined based on the inequality established by N, E ULsubband , and PRB SBFDstarting (PRB SBFDstarting is obtained according to equation 1), i.e. adjusting PRB SBFDstarting obtained from equation 1 through the above three parameters.

[0085] Based on the above assumption 1, through equation 1 (assuming that offset does not exist) and the above adjustment method 1, the index of the PRBs determined in the SBFD symbol is: 20-59. The specific process is: PRB SBFDstarting (PRB SBFDstarting =10+139mod 50=49) is determined by equation 1, then, since (49+40-1)>59, PRB SBFDstarting is adjusted based on the above adjustment method 1, and the adjusted PRB SBFDstarting is obtained (i.e. the adjusted PRB SBFDstarting =59-40+1=20), then the continuous 40 PRBs are allocated, so that the PRBs allocated in the SBFD symbol are indexed as: 20-59.

[0086] The above adjustment method is only an example, and there are many forms of adjustment to PRB SBFDstarting based on mathematical principles, and the following examples are only examples and are not limited to the following examples.

[0087] For example 1:

[0088] If PRB SBFDstarting >(E ULsubband -N+1), then PRBSBFDstarting = PRB SBFDstarting - (PRB SBFDstarting + N - E ULsubband - 1) = E ULsubband - N + 1; otherwise PRB SBFDstarting is not adjusted (i.e. still determined as PRB SBFDstarting ).

[0089] For example 2:

[0090] If (E ULsubband - PRB SBFDstarting + 1) < N, then PRB SBFDstarting = PRB SBFDstarting - (PRB SBFDstarting + N - E ULsubband - 1) = E ULsubband - N + 1; otherwise PRB SBFDstarting is not adjusted (i.e. still determined as PRB SBFDstarting ).

[0091] The "1" in the above adjustment examples can also be absent, i.e. not needed, and can be replaced by other constant.

[0092] According to mathematical principle, the above equation 1 and adjustment 1 can be transformed as:

[0093] or, . Where offset is optional, if offset is used, the value of offset can be predefined or configured by signaling.

[0094] If the "1" is absent in the above inequality or equation, it will make the maximum index PRB in the UL available PRBs hard to be allocated. The "1" can also be absent, i.e. not needed, and can be replaced by other constant. Or, if PRB SBFDstarting is not contained in the consecutive N PRBs, i.e. if the allocated consecutive N PRBs start from PRB SBFDstarting + 1, then the "1" can also not be needed.

[0095] Mode 2:

[0096] If mode 2 is provided for UL transmission, and one frequency domain resource allocation parameter is used to provide the resource (i.e. PRB, assuming the index of the lowest PRB in the allocated PRBs for UL transmission in non-SBFD symbols (UL BWP) is PRB nonSBFDstarting, and is allocated consecutive N PRBs), the resource allocated to the UL transmission in the SBFD symbol can be determined by at least one of the following parameters: PRB nonSBFDstarting , N, S ULsubband , N ULsubband , offset. Optionally, the UL transmission is allocated the same number of PRBs in the SBFD symbol and the non-SBFD symbol.

[0097] Optionally, the resource allocated to the UL transmission in the SBFD symbol can be determined by the following procedure: subtracting a target number of PRBs from N ULsubband to obtain a remaining number of PRBs (the target number is less than or equal to N); using the PRB nonSBFDstarting , performing a modulo operation on the remaining number of PRBs, and determining the PRB ULsubband according to the modulo operation result and S SBFDstarting .

[0098] Optionally, the frequency domain resource allocated to the UL transmission in the UL available PRBs (or UL sub-band) of the SBFD symbol can be determined based on the following Equation 2: PRB SBFDstarting = PRB nonSBFDstarting mod (N ULsubband -N)+S ULsubband Equation 2

[0099] Optionally, the frequency domain resource allocated to the UL transmission in the UL available PRBs (or UL sub-band) of the SBFD symbol can also be determined based on any one of the following Equations 3-7: PRB SBFDstarting =PRB nonSBFDstarting mod (N ULsubband -N)+S ULsubband +1 Equation 3 PRB SBFDstarting =(PRB nonSBFDstarting +offset) mod (N ULsubband -N)+S ULsubband +1 Equation 4 PRB SBFDstarting =PRB nonSBFDstarting mod (N ULsubband -(N-1))+S ULsubband Equation 5

[0100] (Equation 5 is simplified: PRB SBFDstarting =PRB nonSBFDstarting mod(N ULsubband –N+1)+S ULsubband ) PRBSBFDstarting = (PRB nonSBFDstarting + offset) mod (N ULsubband - (N - 1)) + S ULsubband Equation 6 PRB SBFDstarting = PRB nonSBFDstarting + 1 mod (N ULsubband - (N - 1)) + S ULsubband + 1 Equation 7

[0101] After PRB SBFDstarting is obtained, from the PRBs with index PRB SBFDstarting (including) the consecutive N PRBs are determined as the PRBs allocated for the UL transmission in the UL available PRBs in the SBFD symbol.

[0102] If there is no "1" in the above equations, it will make the maximum index PRB in the UL available PRBs in the SBFD symbol difficult to be allocated. The "1" can also be absent, i.e., not needed, and the "1" can also be replaced by other constants. Alternatively, if the corresponding PRB is not included in the consecutive N PRBs, i.e., if the allocated consecutive N PRBs start from the PRB SBFDstarting corresponding to PRB SBFDstarting + 1, then the "1" can also not be needed.

[0103] The above offset is optional. If the offset is used, the value of the offset can be predefined or configured by signaling.

[0104] Also, the starting PRB index of the UL available PRBs (or UL subbands) in the SBFD symbol is 0, and the S ULsubband may not be needed. Also, in the UL available PRBs (or PRBs in the UL subbands) in the SBFD symbol and in the PRBs of the UL BWP in the non-SBFD symbol, the same PRB has the same index. That is, the PRB in the UL available PRBs (or UL subbands) in the SBFD symbol follows the index of the corresponding PRB in the UL BWP.

[0105] Based on the above assumption 1, through equation 2 (assuming that the offset is absent), the index of the PRBs determined in the SBFD symbol is: 19-58. The specific process is: using equation 2 to determine PRB SBFDstarting (PRB SBFDstarting= 139 mod (50 - 40) + 10 = 19, so, starting from PRB with index 19 (inclusive) 40 consecutive PRBs are allocated, so, the allocated PRBs in SBFD symbols have indices: 19 - 58.

[0106] Based on the above assumption 1, by equation 3 (assuming offset is not present), the indices of the PRBs determined in SBFD symbols are: 20 - 59. The detailed procedure is: determine PRB SBFDstarting (PRB SBFDstarting = 139 mod (50 - 40) + 10 + 1 = 20, so, starting from PRB with index 20 (inclusive) 40 consecutive PRBs are allocated, so, the allocated PRBs in SBFD symbols have indices: 20 - 59.

[0107] Based on the above assumption 1, by equation 5 (assuming offset is not present), the indices of the PRBs determined in SBFD symbols are: 17 - 56. The detailed procedure is: determine PRB SBFDstarting (PRB SBFDstarting = 139 mod (50 - (40 - 1)) + 10 = 17, so, starting from PRB with index 17 (inclusive) 40 consecutive PRBs are allocated, so, the allocated PRBs in SBFD symbols have indices: 17 - 56.

[0108] If the indices of the allocated PRBs in non-SBFD symbols of assumption 1 are modified to: 131 - 170, by equation 5 (assuming offset is not present), the indices of the PRBs determined in SBFD symbols are: 20 - 59. The detailed procedure is: determine PRB SBFDstarting (PRB SBFDstarting = 131 mod (50 - (40 - 1)) + 10 = 20, so, starting from PRB with index 20 (inclusive) 40 consecutive PRBs are allocated, so, the allocated PRBs in SBFD symbols have indices: 20 - 59.

[0109] For both way one and way two, if mode 2 is provided as UL transmission, UE does not expect (N ULsubband -N) is less than 0, that is, UE does not expect the number of UL available PRBs is less than the number of PRBs allocated in non-SBFD symbols for UL transmission. That is, the maximum number of PRBs that can be allocated by the base station is equal to the number of UL available PRBs (or UL subbands).

[0110] Way three

[0111] If mode 2 is provided for the UL transmission, and one frequency domain resource allocation parameter is used to provide the resource (i.e. PRBs, assuming the lowest PRB index of the PRBs allocated for the UL transmission in the non-SBFD symbols is PRB nonSBFDstarting , and the UL transmission is allocated with consecutive N PRBs), the resource allocated for the UL transmission in the SBFD symbols can be determined by at least one of the following parameters: PRB nonSBFDstarting , N ULBWP , S ULsubband and N ULsubband . Optionally, the UL transmission is allocated with the same number of PRBs in the SBFD symbols and the non-SBFD symbols.

[0112] Optionally, the frequency domain resource allocated for the UL transmission in the UL available PRBs of the SBFD symbols can be determined by the following equation 8 or equation 9:

[0113] After obtaining PRB SBFDstarting , from the PRB with index PRB SBFDstarting (including) consecutive N PRBs are determined as the PRBs allocated for the UL transmission in the UL available PRBs of the SBFD symbols.

[0114] If the starting PRB index of the UL available PRBs (or UL subbands) in the SBFD symbols is 0, the above S ULsubband may not be needed. And in the UL available PRBs (or PRBs in the UL subbands) in the SBFD symbols and in the PRBs of the UL BWP in the non-SBFD symbols, the same PRB has the same index. That is, the PRB in the UL available PRBs (or UL subbands) keeps the index of the corresponding PRB in the UL BWP.

[0115] However, it is possible that the PRBs allocated for the UL transmission in the SBFD symbols based on the above equation 8 or equation 9 exceed the range of the UL available PRBs. For this case, the equation 8 or equation 9 can be further improved, and the idea of the improvement is: reducing PRB SBFDstarting until there are or exceed consecutive N PRBs from the reduced PRB SBFDstarting to E ULsubband , determining the reduced PRB SBFDstarting as the target PRB SBFDstarting allocated for the UL transmission in the SBFD symbols, wherein the target PRB SBFDstarting is determined based on E ULsubband and N.

[0116] The PRB can be determined based on Equation 8 or Equation 9. SBFDstarting If (PRB) SBFDstarting +N-1)>E ULsubband Then adjust the PRB according to the following adjustment method 2. SBFDstarting PRB SBFDstarting =PRB SBFDstarting -(PRB SBFDstarting +N-1-E ULsubband ) = E ULsubband -N+1.

[0117] If (PRB) SBFDstarting +N-1)≤E ULsubband Do not adjust PRB SBFDstarting (The PRB is still determined based on Equation 8 or Equation 9) SBFDstarting ).

[0118] If the absence of "1" in the above inequalities or equations would make it difficult to allocate the largest index PRB among the available PRBs in the UL, then "1" can be omitted, meaning it does not exist and is not needed. "1" can also be replaced by other constants. Alternatively, if the PRB... SBFDstarting The corresponding PRB is not included in N consecutive PRBs, that is, if the N consecutive PRBs assigned are from PRBs SBFDstarting If the PRB corresponding to +1 is used, then "1" may not be necessary.

[0119] This adjustment process is based on N, E ULsubband and PRB SBFDstarting (PRB SBFDstarting It is determined by the inequality established based on Equation 8 or Equation 9, that is, by adjusting the PRB obtained from Equation 8 or Equation 9 using the above three parameters. SBFDstarting .

[0120] Based on the above assumption 1, using Equation 8 (assuming offset does not exist) and the above adjustment method 2, the index of PRBs determined in the SBFD symbol is 20-59. The specific process is: using Equation 8 to determine the PRBs. SBFDstarting ( Then, since (45+40-1)>59, the PRB is adjusted according to adjustment method 2 above. SBFDstarting (Adjusted PRB) SBFDstarting =59-40+1=20), and then 40 consecutive PRBs are allocated, thus determining the PRB indexes allocated in the SBFD symbol for UL transmission as: 20-59.

[0121] Based on the above assumption 1, the indexes of PRBs determined in SBFD symbol are: 20-59, by equation 9 (assuming offset does not exist) and the above adjustment manner 2. The specific process is: using equation 9 to determine PRB SBFDstarting Then, since (44+40-1)>59, the PRB SBFDstarting is adjusted according to the above adjustment manner 2, (adjusted PRB SBFDstarting =59-40+1=20), and then 40 consecutive PRBs are allocated, so the indexes of PRBs allocated for UL transmission in SBFD symbol are: 20-59.

[0122] The above adjustment manner is only an example, and there are many forms of adjustment of PRB SBFDstarting based on mathematical principles, and the following examples are only examples and are not limited to the following examples.

[0123] Example 1:

[0124] If PRB SBFDstarting >(E ULsubband -N+1), then PRB SBFDstarting =PRB SBFDstarting -(PRB SBFDstarting +N-E ULsubband -1)=E ULsubband -N+1; otherwise, PRB SBFDstarting is not adjusted (i.e., PRB SBFDstarting is still determined according to equation 8 or equation 9).

[0125] If (E ULsubband -PRB SBFDstarting +1)<N, then PRB SBFDstarting =PRB SBFDstarting -(PRB SBFDstarting +N-E ULsubband -1)=E ULsubband -N+1; otherwise, PRB SBFDstarting is not adjusted (i.e., PRB SBFDstarting is still determined according to equation 8 or equation 9).

[0126] The "1" in the above adjustment examples can also be omitted, i.e., it does not exist, and "1" can also be replaced by other constants.

[0127] According to mathematical principles, the above equation 1 and adjustment manner 2 can be transformed as:

[0128] Or, Or, Or, Where, offset is optional, if offset is used, the value of offset can be predefined, or be signaled.

[0129] If there is no "1" in the above inequality or equation, it will make it difficult to allocate the maximum index PRB in the UL available PRBs. "1" can also be default, i.e. not exist, i.e. it is not needed. "1" can also be replaced by other constants. Or, if the PRB SBFDstarting The corresponding PRB is not included in the continuous N PRBs, i.e. if the allocated continuous N PRBs start from PRB SBFDstarting +1, then "1" can also not be needed.

[0130] In some embodiments, if mode 2 is provided as UL transmission (including periodic UL transmission, UL transmission with repetition), the frequency domain resource allocation field (FDRA) in DCI or RRC is used to determine the PRB resources of the UL transmission in non-SBFD symbols, and the method in the above mode 1, mode 2 or mode 3 is used to determine the PRB resources of the UL transmission in SBFD symbols. Even if the first repetition (or the first periodicity, or the first transmission of TBoMS) of the UL transmission is in the SBFD symbol, the corresponding PRB resources for the first repetition transmission are determined based on the method in the above mode 1, mode 2 or mode 3.

[0131] For the above mode 1 and mode 3, if the base station and the UE do not need to revise the PRB SBFDstarting allocation by using the above adjustment method 1 or adjustment method 2, the following restrictions should be ensured by the base station, or the following behaviors should be agreed by the base station and the UE.

[0132] For example 1, the base station ensures that the PRB SBFDstarting allocation based on the above equation 1, equation 8 or equation 9, and in combination with N, so that the PRBs determined in the SBFD symbol do not exceed the range of the UL available PRBs (the frequency domain of the UL subband) in the SBFD symbol (or the PRBs determined in the SBFD symbol are always within the UL available PRBs (the frequency domain of the UL subband) in the SBFD symbol).

[0133] Correspondingly, the UE side behavior is:

[0134] If the UE determines that the PRBs determined in the SBFD symbol for the UL transmission exceed the range of UL available PRBs (frequency domain of UL subband) in the SBFD symbol, the UE drops or delays the UL transmission in the SBFD symbol. Thus, for the UE, although mode 2 is provided as the UL transmission, the UL transmission is actually transmitted only in non-SBFD symbols (even if the UL transmission is delayed, because the location of UL available PRBs in all SBFD symbols is the same) because the PRBs obtained in the SBFD symbol are not all within the range of UL available PRBs (frequency domain of UL subband) in the SBFD symbol.

[0135] Alternatively, the UE does not expect the above-mentioned PRBs determined in the SBFD symbol to exceed the range of UL available PRBs (frequency domain of UL subband) in the SBFD symbol.

[0136] Alternatively, if the UE determines that the PRBs determined in the SBFD symbol exceed the range of UL available PRBs (frequency domain of UL subband) in the SBFD symbol, the UE considers this to be an erroneous configuration, and the UE does not perform the UL transmission.

[0137] In some embodiments, if mode 1 is provided as the UL transmission (including periodic UL transmission, UL transmission with repetition), and if the UL transmission is not configured with frequency hopping (optional), and the first repetition or the first period of the UL transmission is in the SBFD symbol / slot, the UE considers that the PRB resources of the UL transmission in the SBFD symbol are determined based on the frequency domain resource allocation (FDRA) field in the DCI or in the RRC, and the UL transmission uses the same frequency domain resources in non-SBFD symbols as in the SBFD symbol.

[0138] Mode four

[0139] A UL transmission (including type1 CG PUSCH, type 2 CG PUSCH, DCI scheduled PUSCH, TBoMS transmission of PUSCH, PUSCH with repetition) is configured with a RBoffset parameter for determining the starting PRB index of the second hop for the UL transmission. The RBoffset parameter is used to describe the number of PRBs between the starting PRB of the second hop and the starting PRB of the first hop. The RBoffset parameter can be RRC configured with one RBoffset value. Or the RBoffset parameter can be RRC configured with a set of RBoffset values, and further indicated with one RBoffset value from the set using the high bit 1 bit (e.g. the set contains 2 values) or 2 bits (e.g. the set contains 4 values) of the frequency domain resource allocation (FDRA) field in the DCI. In this way, based on the obtained RBoffset value, the UE can determine the starting PRB of the second hop based on the starting PRB of the first hop.

[0140] If mode 2 is provided for the UL transmission, and one frequency domain resource allocation parameter is used to provide the resource (i.e. PRBs, assuming the lowest PRB index of the PRBs allocated for the UL transmission in non-SBFD symbols is PRB nonSBFDstarting , and the UL transmission is allocated with consecutive N PRBs), the resource allocated for the UL transmission in SBFD symbols can be determined based on at least one of the following parameters: the RBoffset of the second hop for the UL transmission, the 1 bit or 2 bits signaling. Alternatively, the UL transmission is allocated with the same number of PRBs in SBFD symbols and non-SBFD symbols.

[0141] Specifically includes:

[0142] The base station and the UE agree to determine the allocated PRBs in SBFD symbols based on at least one of the following:

[0143] Mode 1, the RBoffset value obtained from the RBoffset set of the second hop by the above-mentioned way is directly used to determine the PRBs allocated for the UL transmission in SBFD symbols. For example, the RBoffset value is directly used as the offset between the smallest PRB (index) in the PRBs allocated in non-SBFD symbols and the smallest PRB (index) in the PRBs allocated in SBFD symbols. Obviously, based on the RBoffset value and the PRBs allocated in non-SBFD symbols (including the number and location of PRBs), the PRBs allocated in SBFD symbols can be obtained.

[0144] In Mode 2, if the PRBs allocated for the UL transmission in SBFD symbols are determined based on the signaling of the high bits (1 bit or 2 bits) in the DCI, the 1 bit or 2 bits signaling is from a set of RBoffset values dedicated for resource allocation between SBFD symbols and non-SBFD symbols, and the indicated RBoffset value is used to determine the PRBs allocated for the UL transmission in SBFD symbols. The set of RBoffset values dedicated for resource allocation between SBFD symbols and non-SBFD symbols is configured by RRC signaling, which can include 2 RBoffset values or 4 RBoffset values. Note that the RBoffset value includes at least one of the following definitions: the RBoffset value is used to describe the offset of the smallest PRB (index) in the allocated PRBs in SBFD symbols and the smallest PRB (index) in the allocated PRBs in non-SBFD symbols; the RBoffset value is used to describe the offset of the smallest PRB (index) in the allocated PRBs and is relative to the starting PRB (index) of the UL subband (or UL available PRBs) in SBFD symbols (in this case, the frequency hopping between slots can be enabled). Obviously, based on the RBoffset value and the allocated PRBs in non-SBFD symbols (including the number and location of PRBs), the PRBs allocated for SBFD symbols can be obtained.

[0145] In addition to the above-mentioned modes, for type1 CG PUSCH, the following mode can also be directly considered to determine the PRBs allocated in SBFD symbols. For example, a RBoffset value is configured in rrc-ConfiguredUplinkGrant in ConfiguredGrantConfig corresponding to a type1 CG PUSCH. The RBoffset value includes at least one of the following definitions: the RBoffset value is used to describe the offset of the smallest PRB (index) in the allocated PRBs in SBFD symbols and the smallest PRB (index) in the allocated PRBs in non-SBFD symbols; the RBoffset value is used to describe the offset of the smallest PRB (index) in the allocated PRBs and is relative to the starting PRB (index) of the UL subband (or UL available PRBs) in SBFD symbols. Obviously, based on the RBoffset value and the allocated PRBs in non-SBFD symbols (including the number and location of PRBs), the PRBs allocated for SBFD symbols can be obtained.

[0146] In embodiments, the allocated PRBs are PRB resource allocation based on resource allocation type 1 or resource allocation type 0 (see TS 38.214 for details). If intra-slot or inter-slot frequency hopping is enabled, the RBoffset value obtained by the above-mentioned method 1 or method 2 is set to 0 by default (it can also be considered that the above-mentioned method 1 or method 2 does not need to be performed), but the RBoffset value obtained based on the second frequency hopping RBoffset set is taken as the offset for determining the minimum PRB (index) in the SBFD symbol. The allocated PRBs in the SBFD symbol obtained by the above-mentioned method do not exceed the frequency domain range of the UL sub-band (UL available PRBs).

[0147] For an UL transmission, if the UL transmission is performed in the SBFD symbol and / or non-SBFD symbol, because the interference conditions in the SBFD symbol and non-SBFD symbol are different, the transmission parameters of the transmission (including but not limited to PDSCH, PDCCH, CSI-RS, PUSCH, PUCCH, SRS) in the SBFD symbol and non-SBFD symbol are determined based on a unified TCI state architecture, or only for the UL transmission. The transmission parameters can include at least one of the following: power control information, spatial domain filter or spatial domain transmission filter.

[0148] FIG. 5 is a related art unified TCI state activation / deactivation MAC CE (Medium Access Control Control Element), but the MAC CE cannot well distinguish between the SBFD symbol and the non-SBFD symbol, so the following embodiments provide a new structure of the unified TCI state activation / deactivation MAC CE, which can indicate the transmission parameters of the transmission in the SBFD symbol and the non-SBFD symbol, especially the power control information and the spatial domain filter.

[0149] FIG. 6 is a flowchart of a method for determining transmission parameters according to an embodiment of the present application. As shown in FIG. 6, the method can include:

[0150] S601, in response to a transmission being performed in a non-SBFD symbol and / or an SBFD symbol, determine the transmission parameters corresponding to the transmission in the non-SBFD symbol or the SBFD symbol based on a MAC CE.

[0151] The MAC CE is a TCI-state active / deactivated MAC CE, or the MAC CE has the structure of a TCI-state active / deactivated MAC CE. The MAC CE includes first information indicating the symbol type associated with other parameters contained in the MAC CE. The aforementioned transmission includes one of the following: downlink transmission, uplink transmission.

[0152] That is, define a new structure with TCI state activation / deactivation MAC CE to indicate the transmission parameters corresponding to a transmission in a non-SBFD symbol or an SBFD symbol.

[0153] For example, the first information could be "1" or "0", indicating whether the other parameters contained in the MAC CE are associated with an SBFD symbol or a non-SBFD symbol, respectively.

[0154] Optionally, the MAC CE may also include at least one of the following other parameters:

[0155] The Serving Cell ID is used to identify a serving cell, meaning that the MAC CE is applied to that serving cell. The Serving Cell ID can be 5 bits.

[0156] The DL BWP ID (Downlink Partial Bandwidth Identifier) ​​is used to identify the downlink BWP, meaning that the MAC CE applies to this DL BWP. This DL BWP ID can be 2 bits. In the SBFD symbol, this DL BWP refers to the DL BWP that intersects with the DL subband in the frequency domain. In other words, the Transmission Configuration Indicator (TCI) state defined by the MAC CE applies to DL reception within the PRBs (UL-available PRBs) where the DL BWP and DL subband intersect in the frequency domain.

[0157] UL BWP ID (Uplink Part Bandwidth ID), used to identify an uplink BWP, that is, the MAC CE is applied to the UL BWP. The UL BWP ID can be 2 bits. In SBFD symbols, the UL BWP refers to the UL BWP that has intersection with the UL subband in the frequency domain. That is, the TCI state defined by the MAC CE is applied to the UL transmission in the intersection PRBs (UL available PRBs) of the UL BWP and the UL subband in the frequency domain.

[0158] P i , used to indicate whether each TCI codepoint has multiple TCI states or a single TCI state.

[0159] TCI state ID, used to identify a TCI state.

[0160] CORESET Pool (Control Resource Set Pool) ID, used to identify a control resource set pool.

[0161] D / U, used to indicate whether the TCI state ID in the same octet is used for joint / downlink or uplink TCI state.

[0162] R, used to identify a reserved bit.

[0163] In the embodiments of the present application, a MAC CE based on unified TCI state activation / deactivation is provided, as shown in FIG. 7, the first bit in the first byte of the MAC CE is set as the first information, and the first information is used to indicate the symbol type associated with other parameters contained in the MAC CE.

[0164] The CORESET Pool ID is replaced by the first information, and the positions of other parameters in the MAC CE are maintained. For example, the first bit of the Ooc 1 of the MAC CE is set as the first information, which indicates whether the MAC CE is associated with SBFD symbols or non-SBFD symbols. For example, “1” and “0” are predefined to correspond to SBFD symbols / slots and non-SBFD symbols / slots respectively. Further, other parameters in the MCA CE and transmission parameters associated with other parameters are all applicable to the symbol type associated with the MAC CE.

[0165] Compared with the MAC CE in FIG. 5, the MAC CE (as shown in FIG. 7) provided by the embodiment of the application lacks a CORESET Pool ID. In this way, the base station and the UE agree that, for the case of a single transmission and receiving point (TRP), only CORESET Pool ID = 0 or 1 is configured for one TRP, and 0 and 1 cannot be configured at the same time, that is, only one CORESET Pool ID is configured as a single TRP. Further, it is indicated that the TCI state in the MAC CE is applicable to all CORESETs associated with the CORESET Pool ID 0 or 1. That is, the MAC CE provided by the embodiment of the application can adapt to the single-TRP scenario.

[0166] The explanations of other parameters can refer to the descriptions in the above embodiments, and the embodiment will not be described here again.

[0167] In one embodiment, a MAC CE based on unified TCI state activation / deactivation is also provided, as shown in FIG. 8, the sixth bit in the second byte of the MAC CE is set as first information, the first information is used to indicate the symbol type associated with other parameters contained in the MAC CE, and the positions of the other parameters contained in the MAC CE in the MAC CE are maintained.

[0168] For example, the predefined “1” and “0” correspond to SBFD symbol / slot and non-SBFD symbol / slot respectively. Further, the other parameters in the MCA CE and the transmission parameters associated with the other parameters are all applicable to the symbol type associated with the MAC CE.

[0169] Alternatively, any reserved bit in the second byte of the MAC CE can be set as the first information, which is used to indicate the symbol type associated with the other parameters contained in the MAC CE. Further, the other parameters in the MCA CE and the transmission parameters associated with the other parameters are all applicable to the symbol type associated with the MAC CE.

[0170] In the embodiment, the CORESET Pool ID is used to identify the control resource set pool, which is configured by coresetPoolIndex. Further, the CORESET Pool ID is set to “1”, indicating that the TCI state in the MAC CE is applicable to all CORESETs associated with the CORESET Pool ID 1; the CORESET Pool ID is set to “0”, indicating that the TCI state in the MAC CE is applicable to all CORESETs associated with the CORESET Pool ID 0.

[0171] The explanations of other parameters can refer to the descriptions in the above embodiments, which will not be repeated here.

[0172] In one embodiment, a MAC CE based on unified TCI state activation / deactivation is also provided, as shown in FIG. 9, the first bit in the first byte of the MAC CE is a reserved bit, and the first information is set in the sixth bit of the second byte of the MAC CE, wherein the CORESET Pool ID is cancelled, and the positions of other parameters in the MAC CE are maintained.

[0173] For example, the predefined “1” and “0” correspond to SBFD symbol / slot and non-SBFD symbol / slot respectively. Further, other parameters in the MCA CE and the transmission parameters associated with other parameters are all applicable to the symbol type associated with the MAC CE.

[0174] Alternatively, any reserved bit in the second byte of the MAC CE can be set as the first information, for indicating the symbol type associated with other parameters contained in the MAC CE. Further, other parameters in the MCA CE and the transmission parameters associated with other parameters are all applicable to the symbol type associated with the MAC CE.

[0175] Compared with the MAC CE in FIG. 5, the MAC CE (as shown in FIG. 9) provided by the embodiments of the present application lacks the CORESET Pool ID. In this way, the base station and the UE agree that for the case of a single TRP, only CORESET Pool ID = 0 or 1 is configured for a TRP, and 0 and 1 cannot be configured at the same time, that is, only one CORESET Pool ID is configured as a single TRP. Further, it is indicated that the TCI state in the MAC CE is applicable to all CORESETs associated with CORESET Pool ID 0 or 1. That is, the MAC CE provided by the embodiments of the present application can adapt to the single TRP scenario.

[0176] The explanations of other parameters can refer to the descriptions in the above embodiments, which will not be repeated here.

[0177] For an UL transmission (including but not limited to PUCCH, PUSCH or SRS), the UL transmission can be performed in SBFD symbols and non-SBFD symbols based on 2 UL resources associated with the same UL resource ID, the 2 UL resources are associated with non-SBFD symbols and SBFD symbols respectively. For example, one UL resource is indicated by the related parameters and is associated with non-SBFD symbols, and another UL resource is indicated by the related parameters and is associated with SBFD symbols. Taking an UL transmission configured with frequency hopping (including intra-slot frequency hopping or inter-slot frequency hopping) as an example, the UL transmission is performed in SBFD symbols and non-SBFD symbols, and the UL transmission is configured with frequency hopping, one UL resource ID is configured with two sets of frequency hopping parameters for SBFD symbols and non-SBFD symbols respectively. For example, the starting PRB of the first frequency hopping in non-SBFD symbols is indicated by the parameter startingPRB, and the starting PRB of the second frequency hopping in non-SBFD symbols is indicated by the parameter secondHopPRB. The starting PRB of the first frequency hopping in SBFD symbols is indicated by the parameter startingPRB_2, and the starting PRB of the second frequency hopping in SBFD symbols is indicated by the parameter secondHopPRB_2.

[0178] However, after mode 2 is provided to the UL transmission, that is, after SBFD symbols and non-SBFD symbols are introduced, the above-mentioned parameters startingPRB and secondHopPRB, or startingPRB_2 and secondHopPRB_2 may not be configured, and for this case, the first communication node and the second communication node can perform the UL transmission according to the method provided in the following embodiments. For ease of description, the following takes the first communication node as the UE and the second communication node as the base station as an example.

[0179] FIG. 10 is a flow diagram of a transmission method provided in an embodiment of the present application. The method is applied to a first communication node, as shown in FIG. 10, and the method can include:

[0180] S1001, in the case that an UL transmission can be performed in non-SBFD symbols and SBFD symbols and nominally provided with the following parameters, if the UL transmission is configured with UL resources that are not configured with parameters in non-SBFD symbols, and the UL resources are configured with parameters in SBFD symbols, the first communication node performs the UL transmission according to a first processing manner.

[0181] S1002, if the parameters for UL resource configured in non-SBFD symbols and the parameters for UL resource not configured in SBFD symbols, the first communication node performs UL transmission according to a second processing manner.

[0182] The above parameters include at least one of the following parameters based on SBFD symbols and non-SBFD symbols respectively: parameters for determining the first frequency hopping physical resource block of UL transmission, parameters for determining the second frequency hopping physical resource block of UL transmission, parameters for configuring UL transmission to perform intra-slot frequency hopping, parameters for configuring UL transmission not to perform intra-slot frequency hopping, parameters for configuring UL transmission to perform inter-slot frequency hopping, parameters for configuring UL transmission not to perform inter-slot frequency hopping, parameters for determining the physical resource block of UL transmission in SBFD symbols, and parameters for determining the physical resource block of UL transmission in non-SBFD symbols.

[0183] The nominal provision of the following parameters means that the parameter is optionally configured on the signaling structure, that is, the base station can not configure the parameter.

[0184] Optionally, the above frequency hopping can include inter-slot frequency hopping or intra-slot frequency hopping.

[0185] Optionally, the first processing manner includes one of the following:

[0186] Manner 1: UL transmission is performed, and the parameters used in non-SBFD symbols are determined based on the parameters in SBFD symbols.

[0187] For example, if the UL transmission is configured to perform frequency hopping (hopping in SBFD symbols and non-SBFD symbols), and the UL resource of the UL transmission is not configured with the starting PRB of the first hop and the second hop in the non-SBFD symbols, i.e., the parameters startingPRB and secondHopPRB are not configured, but the UL resource ID is configured with the starting PRB of the first hop and the second hop in the SBFD symbols, i.e., the parameters startingPRB_2 and secondHopPRB_2 are configured, the UE performs the UL transmission, and the UL resource used in the non-SBFD symbols is the same as the UL resource used in the SBFD symbols, i.e., both are determined by the parameters startingPRB_2 and secondHopPRB_2.

[0188] Mode 2: Perform the UL transmission, and the UL resource used in the non-SBFD symbols is the same as the UL resource used in the SBFD symbols, and the UL resource used in the non-SBFD symbols is determined based on the parameters in the SBFD symbols.

[0189] For example, if the UL transmission is configured to perform frequency hopping (hopping in SBFD symbols and non-SBFD symbols), and the UL resource of the UL transmission is not configured with the starting PRB of the first hop and the second hop in the non-SBFD symbols, i.e., the parameters startingPRB and secondHopPRB are not configured, but the UL resource ID is configured with the starting PRB of the first hop and the second hop in the SBFD symbols, i.e., the parameters startingPRB_2 and secondHopPRB_2 are configured, the UE performs the UL transmission, and the UL resource used in the non-SBFD symbols is the same as the UL resource used in the SBFD symbols, i.e., both are determined by the parameters startingPRB_2 and secondHopPRB_2.

[0190] Optionally, the second processing manner comprises one of the following:

[0191] Manner 1: performing the UL transmission, and the UL resource used in the SBFD symbol is the same as the UL resource used in the non-SBFD symbol, and the UL resource used in the SBFD symbol is determined based on the parameter in the non-SBFD symbol.

[0192] Taking frequency hopping as an example, if the UL resource is configured in the starting PRB of the first and second frequency hops in the non-SBFD symbol, i.e., the parameters startingPRB and secondHopPRB are configured, but the UL resource is not configured in the starting PRB of the first and second frequency hops in the SBFD symbol, i.e., the parameters startingPRB_2 and secondHopPRB_2 are not configured, the UE performs the UL transmission, and the UL resource used in the SBFD symbol is the same as the UL resource used in the non-SBFD symbol, i.e., both are determined by the parameters startingPRB and secondHopPRB.

[0193] Manner 2: performing the UL transmission, and the UL resource used in the SBFD symbol is the same as the UL resource used in the non-SBFD symbol, and the UL resource used in the SBFD symbol is determined based on the parameter in the non-SBFD symbol, and the first communication node expects / requires the UL resource determined based on the parameter in the non-SBFD symbol to be valid in the SBFD symbol.

[0194] Taking frequency hopping as an example, if the UL resource is configured in the starting PRB of the first and second frequency hops in the non-SBFD symbol, i.e., the parameters startingPRB and secondHopPRB are configured, but the UL resource is not configured in the starting PRB of the first and second frequency hops in the SBFD symbol, i.e., the parameters startingPRB_2 and secondHopPRB_2 are not configured, the UE performs the UL transmission, and the UL resource used in the SBFD symbol is the same as the UL resource used in the non-SBFD symbol, i.e., both are determined by the parameters startingPRB and secondHopPRB, and the first communication node expects / requires the UL resource to be valid in the SBFD symbol (i.e., the UL resource is in the UL available PRB or UL sub-band).

[0195] Mode 3, if the UL resource determined based on the parameters in the non-SBFD symbol is valid in the SBFD symbol, the UL transmission is performed, and the UL resource used in the SBFD symbol is the same as the UL resource used in the non-SBFD symbol, and the UL resource used in the SBFD symbol is determined based on the parameters in the non-SBFD symbol.

[0196] Continuing to take the frequency hopping as an example, if the UL resource determined by the parameters startingPRB and secondHopPRB is valid in the SBFD symbol (i.e., the UL resource is in the UL available PRBs or the UL subband), the UE performs the UL transmission, and the UL resource used in the SBFD symbol is the same as the UL resource used in the non-SBFD symbol, i.e., both are determined by the parameters startingPRB and secondHopPRB.

[0197] Mode 4, if the UL resource determined based on the parameters in the non-SBFD symbol is invalid in the SBFD symbol, the UL transmission is only performed in the non-SBFD symbol.

[0198] That is, if the UL resource determined based on the parameters in the non-SBFD symbol is invalid in the SBFD symbol (i.e., the UL resource is not in the range of the UL available PRBs or the UL subband), even if the above-mentioned mode 2 is provided for the UL transmission, the first communication node only performs the UL transmission in the non-SBFD symbol.

[0199] Mode 5, the UL transmission is performed in the SBFD symbol and no frequency hopping is performed, and the UL transmission is performed in the non-SBFD symbol and frequency hopping is performed.

[0200] Mode 6, the UL transmission is performed in the SBFD symbol and no frequency hopping is performed, and the UL transmission is performed in the non-SBFD symbol and no frequency hopping is performed.

[0201] FIG. 11 is another flow diagram of a transmission method provided by an embodiment of the present application. The method is applied to a second communication node, as shown in FIG. 11, the method can include:

[0202] S1101, in a case where one UL transmission can be performed in the non-SBFD symbol and the SBFD symbol, and the following parameters are nominally provided, if the UL transmission configuration UL resource is not configured in the parameters in the non-SBFD symbol, and the UL resource is configured in the parameters in the SBFD symbol, the second communication node receives the UL transmission according to a first processing mode.

[0203] S1102, if the UL resource is configured in the parameter of the non-SBFD symbol and the UL resource is not configured in the parameter of the SBFD symbol, the second communication node receives the UL transmission according to a second processing manner.

[0204] The parameters include at least one of the following based on the SBFD symbol and the non-SBFD symbol respectively: a parameter for determining a first frequency hopping physical resource block of the UL transmission, a parameter for determining a second frequency hopping physical resource block of the UL transmission, a parameter for configuring the UL transmission to perform intra-slot frequency hopping, a parameter for configuring the UL transmission not to perform intra-slot frequency hopping, a parameter for configuring the UL transmission to perform inter-slot frequency hopping, a parameter for configuring the UL transmission not to perform inter-slot frequency hopping, a parameter for determining a physical resource block of the UL transmission in the SBFD symbol, and a parameter for determining a physical resource block of the UL transmission in the non-SBFD symbol.

[0205] The nominal provision of the following parameters means that the parameter is optionally configured on the signaling structure, that is, the base station can not configure the parameter.

[0206] Optionally, the first processing method includes one of the following:

[0207] Method 1: receiving the UL transmission, and the parameters used in the non-SBFD symbol are determined based on the parameters in the SBFD symbol.

[0208] Method 2: receiving the UL transmission, and the UL resources used in the non-SBFD symbol are the same as the UL resources used in the SBFD symbol, and the UL resources used in the non-SBFD symbol are determined based on the parameters in the SBFD symbol.

[0209] Optionally, the second processing method includes one of the following:

[0210] Method 1: receiving the UL transmission, and the UL resources used in the SBFD symbol are the same as the UL resources used in the non-SBFD symbol, and the UL resources used in the SBFD symbol are determined based on the parameters in the non-SBFD symbol.

[0211] Method 2: receiving the UL transmission, and the UL resources used in the SBFD symbol are the same as the UL resources used in the non-SBFD symbol, and the UL resources used in the SBFD symbol are determined based on the parameters in the non-SBFD symbol, and the second communication node ensures that the UL resources determined based on the parameters in the non-SBFD symbol are valid in the SBFD symbol.

[0212] Mode 3: If the UL resource determined based on the parameters in non-SBFD symbols is valid in SBFD symbols, receive UL transmission and use the same UL resource in SBFD symbols as in non-SBFD symbols, and the UL resource used in SBFD symbols is determined based on the parameters in non-SBFD symbols.

[0213] Mode 4: If the UL resource determined based on the parameters in non-SBFD symbols is invalid in SBFD symbols, receive UL transmission only in non-SBFD symbols.

[0214] Mode 5: Receive UL transmission in SBFD symbols without frequency hopping, and receive UL transmission in non-SBFD symbols with frequency hopping.

[0215] Mode 6: Receive UL transmission in SBFD symbols without frequency hopping, and receive UL transmission in non-SBFD symbols without frequency hopping.

[0216] Exemplarily, taking a PUSCH transmission as an example, one PUSCH transmission can be configured / provided with RBoffset for SBFD symbols and non-SBFD symbols (denoted as RBoffset1 and RBoffset2 respectively, RBoffset1 is associated with SBFD symbols, and RBoffset2 is associated with non-SBFD symbols, based on the independent RBoffset, the corresponding PUSCH resource in SBFD symbols and non-SBFD symbols can be determined respectively, and the PUSCH resource is used for frequency hopping of the PUSCH transmission), but in some cases, the PUSCH transmission can be configured / provided with RBoffset for SBFD symbols or non-SBFD symbols only, i.e., the PUSCH transmission is configured with RBoffset1 for SBFD symbols only, or the PUSCH transmission is configured with RBoffset2 for non-SBFD symbols only. Further, if mode 1 or mode 2 described above is configured / provided for one PUSCH transmission, the behaviors of UE and base station can be determined according to at least one of the following modes (i.e., the UE needs to determine how the PUSCH transmission is performed, and the base station needs to determine how to receive the PUSCH transmission).

[0217] Based on the above description, for one PUSCH transmission without RBoffset configured for SBFD symbols or for non-SBFD symbols, the behaviors of the base station and the UE should consider the following options.

[0218] Option 1:

[0219] If the PUSCH transmission is not configured with one RBoffset1 for SBFD symbols, but the PUSCH transmission is configured with one RBoffset2 for non-SBFD symbols, one of the following can be supported:

[0220] The frequency hopping of the PUSCH transmission in SBFD symbols is performed by using the PUSCH resources determined by RBoffset2 for non-SBFD symbols. If part or all of the PUSCH resources are outside of the UL available PRBs (or UL sub-bands), the frequency hopping of the PUSCH transmission in SBFD symbols is cancelled, i.e. the frequency hopping of the PUSCH transmission in SBFD symbols is not performed. Further, the frequency hopping of the PUSCH transmission in non-SBFD symbols is performed and based on the PUSCH resources determined by RBoffset2 for non-SBFD symbols.

[0221] Only the frequency hopping of the PUSCH transmission in non-SBFD symbols is performed and based on the PUSCH resources determined by RBoffset2 for non-SBFD symbols, i.e. the frequency hopping of the PUSCH transmission in SBFD symbols is not performed, e.g. equivalent to the frequency hopping function is disabled in SBFD symbols.

[0222] The UE does not expect such a configuration, and the base station should ensure that such a configuration does not occur.

[0223] The UE considers this as a misconfiguration and does not perform the frequency hopping of the PUSCH transmission in SBFD symbols and non-SBFD symbols, i.e. the PUSCH transmission is performed in a non-hopping manner.

[0224] The UE ignores the configuration and does not perform the PUSCH transmission.

[0225] Option 2:

[0226] If the PUSCH transmission is not configured with one RBoffset2 for non-SBFD symbols, but the PUSCH transmission is configured with one RBoffset1 for SBFD symbols, one of the following can be supported:

[0227] The frequency hopping of the PUSCH transmission in non-SBFD symbols is performed and by using the PUSCH resources determined by RBoffset1 for SBFD symbols. The frequency hopping of the PUSCH transmission in SBFD symbols is performed and by using the PUSCH resources determined by RBoffset1 for SBFD symbols.

[0228] performing the frequency hopping of the PUSCH transmission in non-SBFD symbols, e.g. equivalent to the frequency hopping in non-SBFD symbols being disabled.

[0229] The UE does not expect such a configuration, and the base station should ensure that such a configuration does not occur.

[0230] The UE considers this as a misconfiguration and does not perform the frequency hopping of the PUSCH transmission in non-SBFD symbols and in SBFD symbols, i.e. performs the PUSCH transmission in a non-hopping manner.

[0231] The UE ignores the configuration and does not perform the PUSCH transmission.

[0232] FIG. 12 is another flow diagram of a transmission method according to an embodiment of the present application. The method is applied to a first communication node. As shown in FIG. 12, the method can include:

[0234] S1202, in a case where the UL resource IDs are configured in the resource parameters for non-SBFD symbols, and the UL resource IDs are not configured in the resource parameters for SBFD symbols, the first communication node performs the UL transmission in a fourth processing manner.

[0235] The resource parameters include at least one of the following: a parameter for determining a first frequency hopping physical resource block of the UL transmission, a parameter for determining a second frequency hopping physical resource block of the UL transmission, a parameter for configuring the UL transmission to perform intra-slot frequency hopping, a parameter for configuring the UL transmission to not perform intra-slot frequency hopping, a parameter for configuring the UL transmission to perform inter-slot frequency hopping, a parameter for configuring the UL transmission to not perform inter-slot frequency hopping, a parameter for determining a physical resource block of the UL transmission in SBFD symbols, a parameter for determining a physical resource block of the UL transmission in non-SBFD symbols, a parameter for determining a maximum code rate of the UL transmission in SBFD symbols, a parameter for determining a maximum code rate of the UL in non-SBFD symbols, based on the SBFD symbols and the non-SBFD symbols respectively.

[0244] Manner 3: If the UL resources determined based on the resource parameters in the non-SBFD symbol are valid in the SBFD symbol, UL transmission is performed, and the UL resources used in the SBFD symbol are the same as the UL resources used in the non-SBFD symbol, and the UL resources used in the SBFD symbol are determined based on the resource parameters in the non-SBFD symbol.

[0245] Manner 4: If the UL resources determined based on the resource parameters in the non-SBFD symbol are invalid in the SBFD symbol, UL transmission is only performed in the non-SBFD symbol.

[0246] Manner 5: UL transmission is performed in the SBFD symbol without performing frequency hopping, and UL transmission is performed in the non-SBFD symbol with performing frequency hopping.

[0247] Manner 6: UL transmission is performed in SBFD symbols without frequency hopping, and UL transmission is performed in non-SBFD symbols without frequency hopping.

[0248] FIG. 13 is another flow diagram of a transmission method according to an embodiment of the present application. The method is applied to a second communication node. As shown in FIG. 13, the method can include the following steps:

[0249] S1301: If UL transmission is configured with UL resource IDs configured with resource parameters in non-SBFD symbols and UL resource IDs configured with resource parameters in SBFD symbols, the second communication node receives UL transmission according to a third processing manner.

[0250] S1302: If UL resource IDs are configured with resource parameters in non-SBFD symbols and UL resource IDs are not configured with resource parameters in SBFD symbols, the second communication node receives UL transmission according to a fourth processing manner.

[0251] The resource parameters include at least one of the following: a parameter for determining a first frequency hopping physical resource block of UL transmission, a parameter for determining a second frequency hopping physical resource block of UL transmission, a parameter for configuring UL transmission to perform intra-slot frequency hopping, a parameter for configuring UL transmission to not perform intra-slot frequency hopping, a parameter for configuring UL transmission to perform inter-slot frequency hopping, a parameter for configuring UL transmission to not perform inter-slot frequency hopping, a parameter for determining a physical resource block of UL transmission in SBFD symbols, a parameter for determining a physical resource block of UL transmission in non-SBFD symbols, a parameter for determining a maximum code rate of UL transmission in SBFD symbols, and a parameter for determining a maximum code rate of UL in non-SBFD symbols.

[0252] The nominal provision of the following resource parameters means that the resource parameters are optionally configured in the signaling structure, that is, the base station can not configure the resource parameters.

[0253] Optionally, the frequency hopping includes inter-slot frequency hopping or intra-slot frequency hopping.

[0254] Optionally, the third processing manner includes one of the following:

[0256] Manner 2: receive UL transmission and the UL resources used in the SBFD symbols are the same as the UL resources used in the non-SBFD symbols and the UL resources used in the SBFD symbols are determined based on the resource parameters in the non-SBFD symbols.

[0257] Optionally, the fourth processing manner comprises one of the following:

[0258] Manner 1: receive UL transmission and the UL resources used in the SBFD symbols are the same as the UL resources used in the non-SBFD symbols and the UL resources used in the SBFD symbols are determined based on the resource parameters in the non-SBFD symbols.

[0260] Manner 3: receive UL transmission and the UL resources used in the SBFD symbols are the same as the UL resources used in the non-SBFD symbols and the UL resources used in the SBFD symbols are determined based on the resource parameters in the non-SBFD symbols if the UL resources determined based on the resource parameters in the non-SBFD symbols are valid in the SBFD symbols.

[0262] Manner 5: receive UL transmission in the SBFD symbols and do not hop and receive UL transmission in the non-SBFD symbols and hop.

[0263] Manner 6: receive UL transmission in the SBFD symbols and do not hop and receive UL transmission in the non-SBFD symbols and do not hop.

[0264] Exemplarily, taking one PUCCH transmission as an example, one pucch-Resourcd can be configured / provided with PUCCH resources for SBFD symbols and non-SBFD symbols (denoted as PUCCH resource 1 for SBFD symbols and PUCCH resource 2 for non-SBFD symbols respectively), but in some cases, the pucch-Resourcd can be configured / provided with PUCCH resources for SBFD symbols or non-SBFD symbols only, i.e. the pucch-Resourcd is configured with PUCCH resource 1 for SBFD symbols only, or the pucch-Resourcd is configured with PUCCH 2 for non-SBFD symbols only. Further, if the above mode 1 or mode 2 is configured / provided for one PUCCH transmission, and the PUCCH transmission is configured to use the PUCCH resource corresponding to the pucch-Resourcd, the base station and the UE should agree on the following at least one way to clarify their behaviors (i.e. the UE needs to clarify how the PUCCH transmission is performed? The base station needs to clarify how to receive the PUCCH transmission?).

[0265] For one pucch-Resourcd, if no PUCCH resource is configured for SBFD symbols or for non-SBFD symbols, if the pucch-Resourcd is configured for one PUCCH transmission, the base station and the UE behaviors should consider the following options.

[0266] Option 1:

[0267] If the pucch-Resourcd is not configured with one PUCCH resource for SBFD symbols, but the pucch-Resourcd is configured with one PUCCH resource for non-SBFD symbols, and if the above mode 1 is provided for the PUCCH transmission, and it is determined that the PUCCH transmission will be performed in SBFD symbols only, one of the following can be supported:

[0268] The PUCCH transmission is performed in SBFD symbols, and the PUCCH transmission is performed in SBFD symbols by using the PUCCH resource provided by the pucch-Resourcd and for non-SBFD symbols; if part or all of the PUCCH resource is outside the UL available PRBs (or UL sub-band), the PUCCH transmission in SBFD symbols is invalid, e.g. the PUCCH transmission in SBFD symbols in the slot is discarded.

[0269] The UE does not expect such a configuration, and the base station should ensure that such a configuration does not occur.

[0270] The UE considers that there is a misconfiguration and does not perform the PUCCH transmission.

[0271] The UE ignores the configuration and does not perform the PUCCH transmission.

[0272] Option 2:

[0273] If the pucch-ResourceId is not configured with one PUCCH resource for SBFD symbols, but the pucch-ResourceId is configured with one PUCCH resource for non-SBFD symbols, and if the above Mode 1 is provided for the PUCCH transmission, and it is determined that the PUCCH transmission will be performed only in non-SBFD symbols, then one of the following can be supported:

[0274] The PUCCH transmission is performed normally, i.e., the PUCCH transmission in non-SBFD symbols is performed and the PUCCH transmission in SBFD symbols is performed by using the PUCCH resource provided by the pucch-ResourceId and for non-SBFD symbols.

[0275] Option 3:

[0276] If the pucch-ResourceId is not configured with one PUCCH resource for SBFD symbols, but the pucch-ResourceId is configured with one PUCCH resource for non-SBFD symbols, and if the above Mode 2 is provided for the PUCCH transmission, then one of the following can be supported:

[0277] The PUCCH transmission is performed in SBFD symbols and the PUCCH transmission in SBFD symbols is performed by using the PUCCH resource provided by the pucch-ResourceId and for non-SBFD symbols; if part or all of the PUCCH resource is outside of the UL available PRBs (or UL sub-band), then the PUCCH transmission in SBFD symbols is invalid, e.g., the PUCCH transmission in SBFD symbols in a slot is dropped / postponed.

[0278] The PUCCH transmission is performed only in non-SBFD symbols and the PUCCH transmission in non-SBFD symbols is performed using the PUCCH resource associated with non-SBFD symbols of the pucch-ResourceId, i.e., the UE considers that the PUCCH transmission is updated to Mode 1 and the PUCCH transmission is performed only in non-SBFD symbols. That is, the PUCCH transmission is not performed in SBFD symbols.

[0279] The UE does not expect such a configuration, and the base station should ensure that such a configuration does not occur.

[0280] The UE considers this a misconfiguration and does not perform the PUCCH transmission.

[0281] The UE ignores the configuration and does not perform the PUCCH transmission.

[0282] Option 4:

[0283] If the pucch-ResourceId is not configured with one PUCCH resource for non-SBFD symbols, but the pucch-ResourceId is configured with one PUCCH resource for SBFD symbols, and if the above Mode 1 is provided to the PUCCH transmission, and it is determined that the PUCCH transmission will be performed only in non-SBFD symbols, then one of the following can be supported:

[0284] The PUCCH transmission in non-SBFD symbols is performed, and the PUCCH transmission in non-SBFD symbols is performed by using the PUCCH resource provided by the pucch-ResourceId and for SBFD symbols. In this case, the PUCCH resource must be in the UL available PRBs (or UL sub-band) in non-SBFD symbols, since the bandwidth of the UL BWP is larger than the bandwidth of the UL available PRBs.

[0285] The UE does not expect such a configuration, and the base station should ensure that such a configuration does not occur.

[0286] The UE considers this a misconfiguration and does not perform the PUCCH transmission.

[0287] The UE ignores the configuration and does not perform the PUCCH transmission.

[0288] Option 5:

[0289] If the pucch-ResourceId is not configured with one PUCCH resource for non-SBFD symbols, but the pucch-ResourceId is configured with one PUCCH resource for SBFD symbols, and if the above Mode 1 is provided to the PUCCH transmission, and it is determined that the PUCCH transmission will be performed only in SBFD symbols, then one of the following can be supported:

[0290] The PUCCH transmission is normally performed. That is, the PUCCH transmission in non-SBFD symbols is performed and the PUCCH transmission in SBFD symbols is performed by using the PUCCH resource provided by the pucch-Resourid and for SBFD symbols.

[0291] Option 6:

[0292] If the pucch-Resourid does not provide one PUCCH resource for non-SBFD symbols, but the pucch-Resourid provides one PUCCH resource for SBFD symbols, and if the above-mentioned Option 2 is provided for the PUCCH transmission, one of the following can be supported:

[0293] The PUCCH transmission in non-SBFD symbols is performed and the PUCCH transmission in SBFD symbols is performed by using the PUCCH resource provided by the pucch-Resourid and for SBFD symbols. In this case, the PUCCH resource must be in the UL available PRBs (or UL sub-band) in non-SBFD symbols since the bandwidth of the UL BWP is larger than the bandwidth of the UL available PRBs.

[0294] Only the PUCCH transmission in SBFD symbols is performed and the PUCCH transmission is performed using the PUCCH resource of SBFD symbols associated with the pucch-Resourid, that is, the UE considers that the PUCCH transmission is updated to Option 1 and is only performed in SBFD symbols. That is, the PUCCH transmission is not performed in non-SBFD symbols.

[0295] The UE does not expect such a configuration and the base station should ensure that such a configuration does not occur.

[0296] The UE considers that it is a misconfiguration and does not perform the PUCCH transmission.

[0297] The UE ignores the configuration and does not perform the PUCCH transmission.

[0298] In one embodiment, the triggering of the above-mentioned frequency hopping function is by the following parameters:

[0299] intraSlotFrequencyHopping (intra-slot frequency hopping), which is used to configure the frequency hopping of UL transmission within a slot. This parameter can be configured separately for the above-mentioned mode 1 and mode 2. That is, if the above-mentioned mode 1 is provided for UL transmission, one parameter (denoted as intraSlotFrequencyHopping_1) is provided for mode 1 to determine whether the UL transmission based on mode 1 is frequency hopped within a slot. If the above-mentioned mode 2 is provided for UL transmission by the UE, another parameter (denoted as intraSlotFrequencyHopping_2) is provided for mode 2 to determine whether the UL transmission based on mode 2 is frequency hopped within a slot. Alternatively, the parameter intraSlotFrequencyHopping can be shared by mode 1 and mode 2, i.e. the UL transmission based on mode 1 and mode 2 is determined whether to be frequency hopped within a slot based on the parameter intraSlotFrequencyHopping.

[0300] interSlotFrequencyHopping (inter-slot frequency hopping), which is used to configure the frequency hopping of UL transmission between slots. This parameter can be configured separately for the above-mentioned mode 1 and mode 2. That is, if the above-mentioned mode 1 is provided for UL transmission, one parameter (denoted as interSlotFrequencyHopping_1) is provided for mode 1 to determine whether the UL transmission based on mode 1 is frequency hopped between slots. If the above-mentioned mode 2 is provided for UL transmission by the UE, another parameter (denoted as interSlotFrequencyHopping_2) is provided for mode 2 to determine whether the UL transmission based on mode 2 is frequency hopped between slots. Alternatively, the parameter interSlotFrequencyHopping can be shared by mode 1 and mode 2, i.e. the UL transmission based on mode 1 and mode 2 is determined whether to be frequency hopped between slots based on the parameter intraSlotFrequencyHopping.

[0301] interSlotFrequencyHopping can also be configured separately for UL transmission in SBFD symbols and UL transmission in non-SBFD symbols. That is, whether the UL transmission performs inter-slot frequency hopping among SBFD slots is based on a parameter associated with SBFD symbols (denoted as interSlotFrequencyHopping_3), and once enabled, the inter-slot frequency hopping for the UL transmission is performed among SBFD slots. Whether the UL transmission performs inter-slot frequency hopping among non-SBFD slots is based on a parameter associated with non-SBFD symbols (denoted as interSlotFrequencyHopping_4), and once enabled, the inter-slot frequency hopping for the UL transmission is performed among non-SBFD slots. Alternatively, one parameter interSlotFrequencyHopping can be used for both SBFD symbols and non-SBFD symbols to determine whether to perform inter-slot frequency hopping, and once enabled, the UL transmission performs inter-slot frequency hopping among SBFD slots and performs inter-slot frequency hopping among non-SBFD slots.

[0302] In one embodiment, after mode 2 is provided to UL transmission, i.e., after SBFD symbols and non-SBFD symbols are introduced, corresponding PUCCH resources and parameters associated with PUCCH resources need to be configured separately for SBFD symbols and non-SBFD symbols to support PUCCH transmission in SBFD symbols and non-SBFD symbols. Some configurations of parameters associated with PUCCH resources are provided below.

[0303] Configuration of associated parameters PUCCH-FormatConfig for PUCCH resources:

[0304] Scheme 1:

[0305] The configuration information in this parameter PUCCH-FormatConfig is shared by PUCCH resources associated with SBFD symbols and non-SBFD symbols.

[0306] For example, a PUCCH resource 1 (assuming associated with SBFD symbols) and a corresponding PUCCH resource 2 (associated with non-SBFD symbols) corresponding to a certain PUCCH format (one type of PUCCH format 0 / 1 / 2 / 3 / 4) use the configuration information in the same PUCCH-FormatConfig parameter. Among them, the PUCCH resource 1 and the PUCCH resource 2 are configured with the same pucch-ResourceId.

[0307] Scheme 1 can naturally keep PUCCH repetition consistent in different symbol types.

[0308] Scheme 2:

[0309] Each of SBFD symbol and non-SBFD symbol is associated with a parameter PUCCH-FormatConfig.

[0310] For example, a certain PUCCH format (one of PUCCH format 0 / 1 / 2 / 3 / 4) corresponds to PUCCH resource 1 (assuming associated with SBFD symbol) and PUCCH resource 2 (associated with non-SBFD symbol) using configurations in respective PUCCH-FormatConfig parameters. Wherein, PUCCH resource 1 and PUCCH2 have the same pucch-ResourceId.

[0311] Scheme 2 is also reasonable because the two types of symbols face different interference and the parameters inside may be different. But from the perspective of PUCCH repetition, scheme 2 cannot directly keep PUCCH repetition consistent in different symbol types, and needs to be configured by the base station to ensure consistency.

[0312] The above scheme 1 and scheme 2 also apply to each specific parameter in PUCCH-FormatConfig. For example, some parameters are as follows:

[0313] maxCodeRate (maximum code rate):

[0314] Base station and UE agreement: Because the interference faced by different symbol types is different, the maximum code rate parameter (maxCodeRate) is configured for different symbol types (SBFD symbol and non-SBFD symbol), including:

[0315] Scheme 1, add a parameter (for example maxCodeRate1) to describe the maximum code rate used by PUCCH transmission in SBFD symbol / slot; The original parameter maxCodeRate describes the maximum code rate used by PUCCH transmission in non-SBFD symbol / slot.

[0316] Scheme 2, associate two values for this parameter (for example maxCodeRate), one value is associated with SBFD symbol, describing the maximum code rate used by PUCCH transmission in SBFD symbol / slot. Another value is associated with non-SBFD symbol / slot, describing the maximum code rate used by PUCCH transmission in non-SBFD symbol / slot.

[0317] Scheme 3, the PUCCH resource 1 and PUCCH resource 2 with the same pucch-Resourld share the parameter maxCodeRate.

[0318] Scheme 4, based on the parameter maxCodeRate, provide an offset parameter, based on which a value can be determined from PUCCH-MaxCodeRate, which is used for the PUCCH resource associated with SBFD symbols. For example, maxCodeRate is applied to non-SBFD symbols, based on which the offset obtains a value applied to SBFD symbols. Also, the offset can be a pre-defined value, thereby saving signaling overhead.

[0319] If 2 PUCCH resources associated with one PUCCH resource ID are configured with maxCodeRate associated with SBFD symbols and maxCodeRate associated with non-SBFD symbols respectively, and if a PUCCH transmission with repetition is triggered, and the above-mentioned Scheme 2 is provided to the PUCCH transmission, the maxCodeRate associated with SBFD symbols and the maxCodeRate associated with non-SBFD symbols are required to be configured with the same value, that is, the PUCCH resource associated with SBFD symbols and the PUCCH resource associated with non-SBFD symbols are required to be configured with the same parameters below: the parameters contained in PUCCH-FormatConfig and the parameters contained in PUCCH-Resource.

[0320] interslotFrequencyHopping (inter-slot frequency hopping):

[0321] The meaning of the parameter is updated as follows: after the parameter is enabled, two PUCCH resources with the same pucch-Resourld can hop between SBFD slots (using the above-mentioned PUCCH resource 1) and hop between non-SBFD slots (using the above-mentioned PUCCH resource 2).

[0322] If the hopping between SBFD slots and the hopping between non-SBFD slots are independent, the parameter needs to consider the following improvement:

[0323] Scheme 1, add a new parameter (e.g. interslotFrequencyHopping1) to describe the PUCCH is allowed to hop between SBFD slots; the original parameter interslotFrequencyHopping describes the PUCCH is allowed to hop between non-SBFD slots.

[0324] Scheme 2, associate two values for the parameter (e.g. interslotFrequencyHopping), one value describes the PUCCH is allowed to hop between SBFD slots. Another value describes the PUCCH is allowed to hop between non-SBFD slots.

[0325] Scheme 3, the PUCCH resource 1 and PUCCH resource 2 with the same pucch-ResourceId share the parameter interslotFrequencyHopping. After the parameter is enabled, the PUCCH resource 1 associated with SBFD symbols hops between SBFD slots, and the PUCCH resource 2 associated with non-SBFD symbols hops between non-SBFD slots.

[0326] Hopping between two types of slots: for example, two slots at the joint of SBFD slots and non-SBFD slots, the PUCCH resource used in the latter slot should keep the maximum separation in frequency domain with the PUCCH resource used in the former slot. For example, based on the maximum separation in frequency domain, it is determined that the PUCCH resource used in the latter slot uses the startingPRB or secondHopPRB associated with the PUCCH resource as the starting PRB of the PUCCH resource.

[0327] For example, one pucch-ResourceSetId corresponds to one PUCCH resource set, and one PUCCH resource set contains one PUCCH resource associated with SBFD symbols and one PUCCH resource associated with non-SBFD symbols. The PUCCH resource associated with SBFD symbols is configured with 8 PUCCH formats 2 / 3 / 4 (32 PUCCH formats 0 / 1) at most, and the PUCCH resource associated with non-SBFD symbols is configured with 8 PUCCH formats 2 / 3 / 4 (32 PUCCH formats 0 / 1) at most.

[0328] The configuration of the associated parameter PUCCH-ResourceSet (PUCCH resource set) for PUCCH resource:

[0329] pucch-ResourceSetId (PUCCH resource set identifier):

[0330] One pucch-ResourceSetId corresponds to one PUCCH resource set, and one PUCCH resource set contains one PUCCH resource associated with SBFD symbols and one PUCCH resource associated with non-SBFD symbols. The PUCCH resource associated with SBFD symbols is configured with 8 PUCCH formats 2 / 3 / 4 (32 PUCCH formats 0 / 1) at most, and the PUCCH resource associated with non-SBFD symbols is configured with 8 PUCCH formats 2 / 3 / 4 (32 PUCCH formats 0 / 1) at most.

[0331] That is, one PUCCH resource set contains both PUCCH resources associated with SBFD symbols and PUCCH resources associated with non-SBFD symbols.

[0332] That is, SBFD symbols and non-SBFD symbols share the same PUCCH resource set, and one PUCCH resource set contains at most 8 PUCCH resources and each PUCCH resource has a corresponding index, and one PUCCH resource associated with SBFD symbols and one PUCCH resource associated with non-SBFD symbols can have the same pucch-ResourceId.

[0333] Alternatively, SBFD symbols and non-SBFD symbols share the same PUCCH resource set, and one PUCCH resource set contains one or more element indexes, which are determined based on the order of PUCCH resources in the PUCCH resource set. Among them, one index is associated with one or two PUCCH resources, and the two PUCCH resources have the same pucch-ResourceId or different pucch-ResourceId. The two PUCCH resources are respectively associated with SBFD symbols and non-SBFD symbols.

[0334] The UE determines the PUCCH resource according to the PRI in the DCI and the type of the slot in which the PUCCH will be transmitted. For example, the UE determines that the PUCCH will be transmitted in the SBFD slot, and then the UE determines one PUCCH resource from the PUCCH resources associated with SBFD symbols in the determined PUCCH resource set based on the PRI. The UE determines that the PUCCH will be transmitted in the non-SBFD slot, and then the UE determines one PUCCH resource from the PUCCH resources associated with non-SBFD symbols in the determined PUCCH resource set based on the PRI.

[0335] The associated parameters of the PUCCH resource PUCCH-Resource:

[0336] For SBFD symbols and non-SBFD symbols, one parameter PUCCH-Resource is associated respectively.

[0337] That is, in one PUCCH-config, two independent parameters PUCCH-Resource are contained, one is associated with SBFD symbols, and the other is associated with non-SBFD symbols.

[0338] That is, a new parameter PUCCH-Resource (denoted as PUCCH-ResourceSBFD) is added, which is used to configure the PUCCH resource of SBFD symbols. The original PUCCH-Resource is associated with non-SBFD symbols and is used to configure the PUCCH resource of non-SBFD symbols.

[0339] Based on this, the PUCCH resource set can be shared in SBFD symbol and non-SBFD symbol, that is, the same PUCCH resource set can be used for SBFD symbol and non-SBFD symbol. Specifically, in the PUCCH resource set, one or more pucch-Resourcids are included, each pucch-Resourcid is associated with 2 PUCCH resources (associated with SBFD symbol and non-SBFD symbol respectively), and the 2 PUCCH resources come from different parameters PUCCH-Resource (for example, one PUCCH resource comes from parameter PUCCH-Resource, and the other comes from the newly added parameter PUCCH-ResourceSBFD).

[0340] If mode 2 is provided to the PUCCH transmission, and the PUCCH transmission is configured to repeat, the PUCCH resources of different repetitions of the PUCCH transmission in SBFD symbol / slot and in non-SBFD symbol / slot are determined as follows:

[0341] The UE determines to perform a PUCCH transmission with repetition by receiving DCI signaling or RRC signaling, and different repetitions of the PUCCH transmission are in SBFD slot and non-SBFD slot respectively, then the UE determines the PUCCH resources of the PUCCH transmission by at least one of the following:

[0342] Scheme 1:

[0343] For the repetition of the PUCCH transmission in the SBFD slot, the UE determines PUCCH resource 1 from the 2 PUCCH resources associated with a pucch-Resourcid, and for the repetition of the PUCCH transmission in the non-SBFD slot, the UE determines PUCCH resource 2 from the 2 PUCCH resources associated with the same pucch-Resourcid.

[0344] Optionally, wherein the PUCCH resource 1 and the PUCCH resource 2 require at least one of the following requirements:

[0345] 1) Share one of the following parameters: PUCCH-format0, PUCCH-format1, PUCCH-format2, PUCCH-format3 or PUCCH-format4.

[0346] 2) is configured with one of the following parameters: PUCCH-format0, PUCCH-format1, PUCCH-format2, PUCCH-format3 or PUCCH-format4, respectively.

[0347] Specifically,

[0348] The PUCCH resource 1 and the PUCCH resource 2 are both PUCCH format 0, and the PUCCH resource 1 and the PUCCH resource 2 are configured with at least one of the following parameters for SBFD symbols and non-SBFD symbols: initialCyclicShift, nrofSymbols, startingSymbolIndex; the PUCCH resource 1 and the PUCCH resource 2 are both PUCCH format 1, and the PUCCH resource 1 and the PUCCH resource 2 are configured with at least one of the following parameters for SBFD symbols and non-SBFD symbols: initialCyclicShift, nrofSymbols, startingSymbolIndex, timeDomainOCC; the PUCCH resource 1 and the PUCCH resource 2 are both PUCCH format 2, and the PUCCH resource 1 and the PUCCH resource 2 are configured with at least one of the following parameters for SBFD symbols and non-SBFD symbols: nrofPRBs, nrofSymbols, startingSymbolIndex; the PUCCH resource 1 and the PUCCH resource 2 are both PUCCH format 3, and the PUCCH resource 1 and the PUCCH resource 2 are configured with at least one of the following parameters for SBFD symbols and non-SBFD symbols: nrofPRBs, nrofSymbols, startingSymbolIndex; the PUCCH resource 1 and the PUCCH resource 2 are both PUCCH format 4, and the PUCCH resource 1 and the PUCCH resource 2 are configured with at least one of the following parameters for SBFD symbols and non-SBFD symbols: nrofSymbols, occ-Length, occ-Index, startingSymbolIndex.

[0349] 3) Share the same PUCCH-FormatConfig. If PUCCH-FormatConfig is configured separately for SBFD symbol and non-SBFD symbol, it is required that the parameters in the two PUCCH-FormatConfig are kept the same, or the PUCCH-FormatConfig associated with SBFD symbol is used in both SBFD symbol and non-SBFD symbol.

[0350] For different PUCCH repetitions, it is required that they are the same in terms of format, maximum code rate and modulation.

[0351] Scheme 2:

[0352] For this PUCCH transmission with repetitions, UE determines one PUCCH resource from the two PUCCH resources associated with the same pucch-ResourceId to be used for the PUCCH repetitions in both SBFD symbol and non-SBFD symbol.

[0353] Optionally, the one PUCCH resource is determined as follows:

[0354] 1) According to the symbol / slot type where the first repetition of this PUCCH transmission is located, the PUCCH resource associated with the symbol / slot type where the first repetition is located is determined from the two PUCCH resources as the one PUCCH resource.

[0355] 2) The PUCCH resource associated with SBFD symbol is selected from the two PUCCH resources as the one PUCCH resource.

[0356] 3) If one of the two PUCCH resources is valid in both SBFD symbol and non-SBFD symbol, this PUCCH resource is selected as the one PUCCH resource. If both of the two resources meet the above requirement, the PUCCH resource associated with SBFD symbol or non-SBFD symbol is selected as the one PUCCH resource.

[0357] An embodiment is provided below to solve the transmission problem of scheduling request (SR) PUCCH.

[0358] Two symbol types, i.e. SBFD symbol and non-SBFD symbol, are proposed in the related art. In addition, two transmission modes, i.e. the following mode 1 and mode 2, are provided.

[0359] Mode 1: means a transmission is provided to perform transmission across different slots, and only allows the transmission in SBFD symbols in SBFD slots or in non-SBFD symbols in non-SBFD slots. For example, a transmission is only restricted in SBFD symbols in SBFD slots, then all transmissions (including repetitions, periodic transmissions) of the transmission can only be in SBFD symbols in SBFD slots. For example, a transmission is only restricted in non-SBFD symbols in non-SBFD slots, then all transmissions (including repetitions, periodic transmissions) of the transmission can only be in non-SBFD symbols in non-SBFD slots.

[0360] Mode 2: means a transmission is provided to perform transmission across different slots, and allows the transmission in SBFD symbols in SBFD slots and in non-SBFD symbols in non-SBFD slots. For example, one transmission (including periodic transmission, repetition transmission) of a transmission is in SBFD symbols in slot n, another transmission of the transmission is in non-SBFD symbols in slot m.

[0361] For a SR configuration, it is periodic and transmitted by PUCCH resource, so, after introducing SBFD symbols and non-SBFD symbols, how to determine the mode associated with the SR configuration? And in the case of the SR configuration associated with mode 1, how to determine whether the SR configuration is associated with SBFD symbols or non-SBFD symbols?

[0362] The base station and the UE agree to inform the UE about the mode associated with the SR configuration according to the following mode.

[0363] Option 1: In the signaling used to provide physical resources for the SR configuration, for example, in the RRC signaling SchedulingRequestResourceConfig, a parameter A is added. Based on the parameter A, it is determined whether the SR configuration is associated with mode 1 or mode 2.

[0364] If the parameter A is set to indicate that an SR configuration is associated with mode 2, the SR PUCCH of the SR configuration can be transmitted at an SR period consisting of SBFD symbols, and can also be transmitted at an SR period consisting of non-SBFD symbols. That is, if at an SR period, the resource corresponding to the SR PUCCH consists of non-SBFD symbols, or consists of SBFD symbols, the SR PUCCH at the SR period can be transmitted. And if at an SR period, the resource only contains SBFD symbols, at the SR period, the PUCCH resource used for the SR transmission is determined to be the PUCCH resource (frequency domain resource) associated with the SBFD, and associated with the PUCCH resource ID associated with the SR configuration. And if at an SR period, the resource only contains non-SBFD symbols, at the SR period, the PUCCH resource used for the SR transmission is determined to be the PUCCH resource associated with the non-SBFD, and associated with the PUCCH resource ID associated with the SR configuration. If at an SR period, the resource contains both SBFD symbols and non-SBFD symbols, the SR transmission at the SR period is prohibited.

[0365] Correspondingly, the base station performs reception of the SR PUCCH according to the parameter A setting and the transmission of the SR PUCCH described above, and details are not repeated.

[0366] Further, if mode 1 is determined to be the SR configuration of the UE based on the parameter A described above, the base station and the UE determine the mode associated with an SR configuration in the following manner, that is, determine in which symbol type the PUCCH of the SR is transmitted.

[0367] Option 1: In the signaling used to provide physical resources for the SR configuration, for example, in the RRC signaling SchedulingRequestResourceConfig, a parameter B is added. Based on the parameter B, it is determined whether the SR configuration is associated with SBFD symbols or non-SBFD symbols.

[0368] If the parameter B is set to indicate that an SR configuration is associated with SBFD symbols, the SR PUCCH of the SR configuration is only transmitted at an SR period consisting of SBFD symbols, that is, at the SR period, the resource (symbols) corresponding to the SR PUCCH are all SBFD symbols. That is, if at an SR period, the resource corresponding to the SR PUCCH contains non-SBFD symbols, the SR PUCCH at the SR period is not transmitted. Correspondingly, the base station performs reception of the SR PUCCH according to the parameter B setting and the transmission of the SR PUCCH described above, and details are not repeated.

[0369] If the parameter B is set to identify a SR configuration associated symbol as non-SBFD symbol, the SR PUCCH of the SR configuration is only transmitted at the SR period composed of non-SBFD symbols, that is, at the SR period, the resources (symbols) corresponding to the SR PUCCH are all non-SBFD symbols. That is, if a SR period, the resources corresponding to the SR PUCCH contain SBFD symbols, the SR PUCCH at the SR period is not transmitted. Correspondingly, the base station performs the reception of the SR PUCCH according to the above parameter B setting and the above SR PUCCH transmission, and details are not repeated.

[0370] The following embodiment is provided to solve the transmission problem of periodic CSI PUCCH.

[0371] The following two symbol types are proposed in the related art, namely SBFD symbol and non-SBFD symbol. In addition, two transmission modes are provided, namely mode 1 and mode 2.

[0372] Mode 1: refers to a transmission provided to perform transmission across different slots, and only allows transmission in SBFD symbols in SBFD slots or in non-SBFD symbols in non-SBFD slots. For example, a transmission is only limited to SBFD symbols in SBFD slots, then all transmissions (including repeated transmissions, periodic transmissions) of the transmission can only be in SBFD symbols in SBFD slots. For example, a transmission is only limited to non-SBFD symbols in non-SBFD slots, then all transmissions (including repeated transmissions, periodic transmissions) of the transmission can only be in non-SBFD symbols in non-SBFD slots.

[0373] Mode 2: refers to a transmission provided to perform transmission across different slots, and allows transmission in SBFD symbols in SBFD slots and in non-SBFD symbols in non-SBFD slots. For example, a transmission of a transmission (including periodic transmission, repeated transmission) in SBFD symbols in slot n, another transmission of the transmission in non-SBFD symbols in slot m.

[0374] For a CSI report configuration, the periodic CSI report therein is transmitted through a PUCCH resource, so after the introduction of SBFD symbols and non-SBFD symbols, how to determine the mode associated with the CSI report configuration? And in the case of mode 1 associated with the CSI report configuration, how to determine whether the CSI report configuration is associated with SBFD symbols or non-SBFD symbols?

[0375] The base station and the UE agree that the UE is informed about whether the CSI reporting configuration is associated with the above-mentioned mode 1 or the above-mentioned mode 2 in the following way.

[0376] Option 1: In the signaling of a CSI reporting configuration, CSI-ReportConfig, or in reportConfigType in CSI-ReportConfig, or in periodic in reportConfigType in CSI-ReportConfig, a parameter C is added. Based on the parameter C, it is determined whether the periodic CSI reporting in the CSI reporting configuration is associated with mode 1 or mode 2.

[0377] If the parameter C is set to identify that a CSI reporting configuration is associated with mode 2, the PUCCH (i.e., CSI PUCCH) of the periodic CSI reporting in the CSI reporting configuration can be transmitted at the periodic CSI reporting of the SBFD symbol or at the periodic CSI reporting of the non-SBFD symbol. That is, if the resource corresponding to the CSI PUCCH at the periodic CSI reporting is composed of non-SBFD symbols or composed of SBFD symbols, the CSI PUCCH at the periodic CSI reporting can be transmitted. And if the resource at the periodic CSI reporting only contains SBFD symbols, the PUCCH resource used by the CSI reporting at the periodic CSI reporting is determined to be the PUCCH resource (frequency resource) associated with the SBFD associated with the PUCCH resource ID associated with the CSI reporting configuration. And if the resource at the periodic CSI reporting only contains non-SBFD symbols, the PUCCH resource used by the CSI reporting at the periodic CSI reporting is determined to be the PUCCH resource associated with the non-SBFD associated with the PUCCH resource ID associated with the CSI reporting configuration. But if the resource at the periodic CSI reporting contains both SBFD symbols and non-SBFD symbols, the CSI PUCCH transmission of the CSI reporting at the periodic CSI reporting is prohibited.

[0378] Correspondingly, the base station performs the reception of the PUCCH of the CSI reporting according to the above-mentioned parameter C setting and the above-mentioned CSI PUCCH transmission of the CSI reporting, and the details are not described again.

[0379] Further, if mode 1 is determined to be the CSI reporting configuration of the UE based on the above-mentioned parameter C, the base station and the UE determine the mode associated with the periodic CSI reporting configuration in the CSI reporting, i.e., determine the CSI PUCCH corresponding to the periodic CSI reporting is transmitted in which symbol type, in the following way.

[0380] Option 1: In the signaling of a CSI report configuration, CSI-ReportConfig, or in reportConfigType of CSI-ReportConfig, or in periodic of reportConfigType of CSI-ReportConfig, a parameter D is added. Based on the parameter D, it is determined whether the periodic CSI report of the CSI report configuration is associated with SBFD symbols or non-SBFD symbols.

[0381] If the parameter D is set to indicate that the symbols associated with a periodic CSI report are SBFD symbols, the CSI PUCCH of the CSI report is only transmitted at the CSI report period composed of SBFD symbols, that is, at the CSI report period, the resources (symbols) corresponding to the CSI PUCCH are all SBFD symbols. The PUCCH resource used by the CSI report is determined as: the PUCCH resource (frequency domain resource) associated with SBFD associated with the PUCCH resource ID associated with the CSI report configuration. That is, if the resources corresponding to the CSI PUCCH at a CSI report period contain non-SBFD symbols, the CSI PUCCH at the CSI report period is not transmitted. If the resources at a CSI report period contain both SBFD symbols and non-SBFD symbols, the CSI PUCCH transmission of the CSI report at the CSI report period is prohibited.

[0382] Correspondingly, the base station performs reception of the CSI PUCCH according to the parameter setting and the CSI PUCCH transmission described above, and details are not repeated.

[0383] If the parameter D is set to indicate that the symbols associated with a CSI report are non-SBFD symbols, the CSI PUCCH of the CSI report is only transmitted at the CSI report period composed of non-SBFD symbols, that is, at the CSI report period, the resources (symbols) corresponding to the CSI PUCCH are all non-SBFD symbols. The PUCCH resource used by the CSI report is determined as: the PUCCH resource (frequency domain resource) associated with non-SBFD associated with the PUCCH resource ID associated with the CSI report configuration. That is, if the resources corresponding to the CSI PUCCH at a CSI report period contain SBFD symbols, the CSI PUCCH at the CSI report period is not transmitted. If the resources at a CSI report period contain both SBFD symbols and non-SBFD symbols, the CSI PUCCH transmission of the CSI report at the CSI report period is prohibited.

[0384] Correspondingly, the base station performs the receiving of the CSIPUCCH according to the above parameter setting and the transmitting of the CSIPUCCH, and details are not repeated here.

[0385] The following embodiment is provided to solve the problem of periodic CSI-RS transmission.

[0386] The following two symbol types are proposed in the related art, namely SBFD symbols and non-SBFD symbols. In addition, two transmission modes are provided, namely mode 1 and mode 2 as follows.

[0387] Mode 1: refers to a transmission being provided to perform transmission across different slots, and only allows transmission in SBFD symbols in SBFD slots or in non-SBFD symbols in non-SBFD slots. For example, a transmission is only limited to SBFD symbols in SBFD slots, and all transmissions of the transmission (including repeated transmissions, periodic transmissions) can only be in SBFD symbols in SBFD slots. For example, a transmission is only limited to non-SBFD symbols in non-SBFD slots, and all transmissions of the transmission (including repeated transmissions, periodic transmissions) can only be in non-SBFD symbols in non-SBFD slots.

[0388] Mode 2: refers to a transmission being provided to perform transmission across different slots, and allows transmission in SBFD symbols in SBFD slots and in non-SBFD symbols in non-SBFD slots. For example, a transmission of a transmission (including periodic transmission, repeated transmission) is in SBFD symbols in slot n, and another transmission of the transmission is in non-SBFD symbols in slot m.

[0389] For a CSI-RS configuration, it is periodically transmitted, so after the introduction of SBFD symbols and non-SBFD symbols, how to determine the mode associated with the CSI-RS configuration? And in the case of associating mode 1 with the resource configuration, how to determine whether the resource configuration is associated with SBFD symbols or non-SBFD symbols?

[0390] The base station and the UE agree to determine whether the CSI-RS is associated with the above mode 1 or the above mode 2 in the following manner.

[0391] Option 1: If the UE determines that one of the configured CSI-ReportConfig is associated with mode 1, and further determines that the CSI-ReportConfig is associated with SBFD symbols, then the CSI-RS reception for the periodicity associated with the CSI-ReportConfig is as follows: If the resource at the CSI-RS periodicity is composed of SBFD symbols only, then the UE receives the CSI-RS at the periodicity. That is, if the resource at the CSI-RS periodicity is composed of non-SBFD symbols only, or is composed of both SBFD symbols and non-SBFD symbols, then the UE does not receive the CSI-RS at the periodicity.

[0392] Option 2: If the UE determines that one of the configured CSI-ReportConfig is associated with mode 1, and further determines that the CSI-ReportConfig is associated with non-SBFD symbols, then the CSI-RS reception for the periodicity associated with the CSI-ReportConfig is as follows: If the resource at the CSI-RS periodicity is composed of non-SBFD symbols only, then the UE receives the CSI-RS at the periodicity. That is, if the resource at the CSI-RS periodicity is composed of SBFD symbols only, or is composed of both SBFD symbols and non-SBFD symbols, then the UE does not receive the CSI-RS at the periodicity.

[0393] An embodiment of SPS configuration corresponding HARQ-ACK PUCCH transmission is provided as follows.

[0394] Two types of symbols, SBFD symbols and non-SBFD symbols, are proposed in the related art. In addition, two transmission modes, mode 1 and mode 2, are provided as follows.

[0395] Mode 1: refers to a transmission is provided to perform transmission across different slots, and only allows transmission in SBFD symbols in SBFD slots or in non-SBFD symbols in non-SBFD slots. For example, a transmission is only restricted in SBFD symbols in SBFD slots, then all transmissions (including repeated transmissions, periodic transmissions) of the transmission can only be in SBFD symbols in SBFD slots. For example, a transmission is only restricted in non-SBFD symbols in non-SBFD slots, then all transmissions (including repeated transmissions, periodic transmissions) of the transmission can only be in non-SBFD symbols in non-SBFD slots.

[0396] Mode 2: means one transmission is provided cross-slot transmission, and allows the transmission in SBFD symbols in SBFD slots and in non-SBFD symbols in non-SBFD slots. For example, one transmission of a transmission (including periodic transmission, repeated transmission) in SBFD symbols in slot n, another transmission of the transmission in non-SBFD symbols in slot m.

[0397] For a HARQ-ACK PUCCH transmission corresponding to one SPS configuration, its transmission location is determined based on the reception location of each SPS PDSCH and the location of the one-time HARQ-ACK transmission indicated from the activation DCI of the SPS configuration. So, after the introduction of SBFD symbols and non-SBFD symbols, how to determine the mode associated with the HARQ-ACK PUCCH transmission (especially in the case of N times repetition)? And in the case of the HARQ-ACK PUCCH transmission associated with mode 1, how to determine whether the HARQ-ACK PUCCH transmission is associated with SBFD symbols or non-SBFD symbols?

[0398] The base station and the UE agree to determine whether the above-mentioned HARQ-ACK PUCCH transmission is associated with the above-mentioned mode 1 or the above-mentioned mode 2 in the following way.

[0399] Option 1: The mode (mode 1 or mode 2) associated with the HARQ-ACK PUCCH transmission corresponding to one SPS configuration is determined to be the same as the mode associated with the SPS configuration. That is, if one SPS configuration is determined to be associated with mode 1 (or mode 2), the HARQ-ACK PUCCH transmission corresponding to the SPS PDSCH at all periods of the SPS configuration is also associated with mode 1 (or mode 2). The UE transmits the HARQ-ACK PUCCH corresponding to the SPS PDSCH at each period of the SPS configuration based on the determined mode 1 (or mode 2).

[0400] Option 2: In the RRC signaling (such as SPS-Config) of one SPS configuration, introduce a parameter E, based on the parameter E to determine the HARQ-ACK PUCCH transmission corresponding to the SPS PDSCH at all periods of one SPS configuration is associated with mode 1 or mode 2.

[0401] Option 3: The base station and the UE agree that the HARQ-ACK PUCCH transmission corresponding to one SPS configuration is always associated with the mode 2. That is, the HARQ-ACK PUCCH transmission corresponding to the SPS PDSCH at different periods of one SPS configuration can be transmitted in the SBFD symbols or in the non-SBFD symbols. For example, the HARQ-ACK PUCCH transmission corresponding to the SPS PDSCH at the first period is transmitted in the SBFD symbols, and the HARQ-ACK PUCCH transmission corresponding to the SPS PDSCH at the second period is transmitted in the non-SBFD symbols.

[0402] Correspondingly, the base station performs the reception of the HARQ-ACK PUCCH according to the above-mentioned parameter E setting and the above-mentioned HARQ-ACK PUCCH transmission, and the details are not repeated.

[0403] Further, if the mode 1 is determined to be the above-mentioned HARQ-ACK PUCCH transmission (which can also have N times of repetition), then the base station and the UE determine whether the HARQ-ACK PUCCH transmission is associated only in the SBFD symbols or only in the non-SBFD symbols in the following way.

[0404] Option 1: for one HARQ-ACK PUCCH transmission with N (N can be 1) repetitions corresponding to one SPS PDSCH of one period of one SPS configuration, the symbols associated with the one HARQ-ACK PUCCH transmission with N repetitions are determined based on the symbol type of the symbols corresponding to the first PUCCH repetition of the N repetitions transmission. For example, the symbols corresponding to the first PUCCH repetition are composed of SBFD symbols, then the N times HARQ-ACK PUCCH transmission are all transmitted in SBFD symbols, and the PUCCH resource used is determined as: associated with the PUCCH resource ID associated with the SPS configuration, and the PUCCH resource (frequency domain resource) associated with SBFD. For example, the symbols corresponding to the first PUCCH repetition are composed of non-SBFD symbols, then the N times HARQ-ACK PUCCH transmission are all transmitted in non-SBFD symbols, and the PUCCH resource used is determined as: associated with the PUCCH resource ID associated with the SPS configuration, and the PUCCH resource (frequency domain resource) associated with non-SBFD. For example, the symbols corresponding to the first PUCCH repetition are composed of SBFD symbols and non-SBFD symbols at the same time, then the UE does not perform the N times HARQ-ACK PUCCH transmission, or postpones the N times HARQ-ACK PUCCH transmission. That is, in turn, each HARQ-ACK PUCCH transmission corresponding to one SPS PDSCH of each period of one SPS configuration is independently determined the symbol type associated, and transmission is performed according to the determined symbol type.

[0405] Option 2: For one HARQ-ACK PUCCH transmission with N (N can be 1) times repetition corresponding to SPS PDSCH at all periods of one SPS configuration, the symbols of the one HARQ-ACK PUCCH transmission with N times repetition are determined based on the symbol type of the symbols corresponding to the first PUCCH repetition of the N times repetition transmission. For example, the symbols corresponding to the first PUCCH repetition are composed of SBFD symbols, then the N times HARQ-ACK PUCCH transmission are all transmitted in SBFD symbols, and the PUCCH resource used is determined as: associated with the PUCCH resource ID associated with the SPS configuration, and the PUCCH resource (frequency domain resource) associated with SBFD. For example, the symbols corresponding to the first PUCCH repetition are composed of non-SBFD symbols, then the N times HARQ-ACK PUCCH transmission are all transmitted in non-SBFD symbols, and the PUCCH resource used is determined as: associated with the PUCCH resource ID associated with the SPS configuration, and the PUCCH resource (frequency domain resource) associated with non-SBFD. For example, the symbols corresponding to the first PUCCH repetition are composed of SBFD symbols and non-SBFD symbols at the same time, then the UE does not perform the N times HARQ-ACK PUCCH transmission, or postpones the N times HARQ-ACK PUCCH transmission.

[0406] The offset of frequency hopping and the offset of determining the resource are shared.

[0407] An embodiment is provided below to solve the problems related to the random access procedure.

[0408] In some embodiments, to provide more random access channel resources (or referred to as physical random access channel occasions, simply ROs), the transmission of physical random access channel (PRACH) can be performed using full duplex resources (e.g., full duplex symbols). The random access channel resources obtained based on the random access channel configuration can fall on full duplex symbols or non-full duplex symbols, and thus can be defined as different types of RACH resources (or different types of ROs). For example, the ROs configured within full duplex symbols are defined as the first type of ROs, and the ROs configured within non-full duplex symbols are defined as the second type of ROs. In some embodiments, at least part of the configured ROs can be determined as valid ROs based on a validity determination rule, and thus at least part of the configured ROs of different types can be respectively determined as valid ROs of different types. In some embodiments, when a specific condition is met, the UE can select multiple ROs from the valid ROs of different types for PRACH repeated transmission (or PRACH transmission with preamble sequence repetition). Specifically, the specific condition includes at least one of the following: Condition 1: the selected multiple ROs have the same frequency domain location. Condition 2: the preamble sequences or PRACH transmissions within the selected multiple ROs use the same transmission power. Condition 3: the preamble sequences or PRACH transmissions within the selected multiple ROs use the same UL spatial domain filter. Condition 4: the preamble sequences / PRACH transmissions within the two types of ROs have no phase continuity requirement for the UE. Condition 5: the selected multiple ROs are associated with the same SSB (synchronization signal / physical broadcast channel block) or the same group of SSBs. Condition 6: the selected multiple ROs are consecutive in time domain, i.e., there is no skipping of ROs associated with the same SSB in time domain. Condition 7: for the selected multiple ROs, the preamble sequence set corresponding to the same SSB is the same. Condition 8: the selected multiple ROs are configured by a set of RACH configurations. Condition 9: the different types of ROs are configured by different RACH configurations. Condition 10: the first preamble sequence transmission in the multiple preamble sequence repetitions is located in a predefined resource type, e.g., full duplex resources. Condition 11: the physical random access channel formats (PRACH formats) carried by the different types of ROs are the same.

[0409] In some embodiments, at least one of the transmission power and the UL spatial domain filter for PRACH transmission with preamble sequence repetition (or PRACH repetition) is determined according to the type of RO in which the first preamble sequence transmission of the preamble sequence repetition is located. In some embodiments, at least one of the transmission power and the UL spatial domain filter for PRACH transmission with preamble sequence repetition (or PRACH repetition) is determined according to the type of the configured RO.
