Description

Technical Field

[0001] The present application relates to the field of communication technologies, and in particular, to a resource determination method, a transmission parameter determination method, a transmission method, a device, and a computer-readable storage medium. Background Art

[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, subband full duplex (SBFD) technology has emerged. The SBFD technology can achieve full duplex on the base station side by dividing non-overlapping uplink / downlink subbands within a single TDD carrier and respectively sending and receiving data on the subbands. Currently, in some transmission configuration modes, UL transmission can be performed in both SBFD symbols and non-SBFD symbols (here, an SBFD symbol refers to a symbol configured with an SBFD subband, and a non-SBFD symbol refers to a symbol not configured with an SBFD subband). However, there is no relevant research in the traditional technology on how to determine the frequency domain resources of UL transmission in such a transmission configuration mode.

[0050] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0051] In order to improve the UL coverage of the TDD system, reduce the delay of UL transmission, and increase the capacity of UL transmission, a SBFD technology for radio resource control (RRC) connected user equipment (UE) has emerged as the times require.

[0052] For the SBFD technology, the UL sub-bands can be configured in some or all of the DL symbols or F (flexible) symbols, but cannot be configured in the UL symbols. For example, a UL sub-band is configured in a DL symbol, and at the same time, DL sub-bands are also configured in this DL symbol. That is to say, the UL sub-bands and DL sub-bands (also known as SBFD sub-bands) are configured in the DL symbols or F symbols simultaneously, but the UL sub-bands and DL sub-bands are prohibited from being configured in the UL symbols. In this case, the uplink Band Width Part (UL BWP) in the UL symbols is used for UL transmission, and the UL sub-bands in the SBFD symbols are used for uplink transmission, but the interference situations in the UL BWP and the UL sub-bands are different.

[0053] The UL sub-bands and DL sub-bands are also called SBFD sub-bands, that is, an SBFD sub-band is configured in the DL symbols / slots of the DL BWP. Generally, this SBFD sub-band includes at least one DL sub-band and one UL sub-band.

[0054] For example, in a 100 MHz TDD carrier, 20 consecutive RBs are configured as the UL sub-bands in the DL symbols / slots of the DL BWP. The remaining frequency domain resources of this DL BWP are the DL sub-bands (the gap can be not configured), or a DL sub-band is also configured in the DL symbols / slots of the DL BWP. In this way, in the DL symbols / slots, the UL sub-bands can be used for UL transmission, and the DL sub-bands can be used for DL transmission. Figure 1 It is a schematic structural diagram of an SBFD sub-band provided by an embodiment of the present application. As Figure 1 shown, an SBFD sub-band includes a UL sub-band and a DL sub-band. This kind of frequency domain pattern is generally called "DUD" (based on the frequency domain structure). Figure 2 It is another schematic structural diagram of an SBFD sub-band provided by an embodiment of the present application. As Figure 2 shown, an SBFD sub-band includes a UL sub-band and a DL sub-band, and the UL sub-band is located below the DL sub-band. This kind of frequency domain pattern is generally called "DU" (based on the frequency domain structure).

[0055] Currently, the SBFD technology has the following characteristics: The base station has the ability to receive in the UL sub-bands and transmit in the DL sub-bands simultaneously in the same time domain. The UE does not have the ability to receive in the UL sub-bands and transmit in the DL sub-bands simultaneously in the same time domain. Here, the UL sub-bands and DL sub-bands are configured in the same OFDM symbol / slot and are frequency division.

[0056] The above-mentioned SBFD sub-band operations are performed within the DL BWP and UL BWP pair, and the DL BWP and UL BWP pair are center frequency aligned.

[0057] In the embodiments of the present application, a symbol configured with an SBFD sub-band is referred to as an SBFD symbol, a slot containing an SBFD symbol is referred to as an SBFD slot, a symbol not configured with an SBFD sub-band is referred to as a non-SBFD symbol, and a slot not containing an SBFD symbol is referred to as a non-SBFD slot.

[0058] To further improve system efficiency, in-band full duplex (IBFD) technology has been studied. IBFD technology means configuring a time-frequency resource within the carrier bandwidth of a carrier, in which the base station can perform simultaneous co-frequency transmission and reception. For example, continuous RBs are configured as an IBFD sub-band within the carrier bandwidth, and the IBFD sub-band is configured in all or part of the symbols, thereby forming a resource for IBFD operation. Figure 3 This is a schematic structural diagram of an IBFD sub-band provided by the embodiments of the present application. As Figure 3 shown, part or all of the carrier bandwidth of a carrier is configured with an IBFD sub-band, and the IBFD sub-band is configured in all or part of the symbols.

[0059] In the embodiments of the present application, a symbol configured with an IBFD sub-band 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 sub-band is referred to as a non-IBFD symbol (i.e., a conventional symbol), and a slot not containing an IBFD symbol is referred to as a non-IBFD slot.

[0060] In the embodiments of the present application, the SBFD sub-band can be understood to include a DL sub-band, a UL sub-band, and a frequency-domain gap. In addition, the SBFD sub-band can also be directly replaced by a UL sub-band or a DL sub-band. For example, configuring the time-domain and frequency-domain resources of an SBFD sub-band can also be replaced by configuring the time-domain and frequency-domain resources of a UL sub-band, or can also be replaced by configuring the time-domain and frequency-domain resources of a DL sub-band.

[0061] The following related methods are described based on the SBFD sub-band, but these methods can also be applied to the IBFD sub-band. For example, only need to replace the SBFD symbols / slots in these methods with IBFD symbols / slots, and replace the non-SBFD symbols / slots with non-IBFD symbols / slots.

[0062] In the embodiments of the present application, a transmission is provided with two modes, specifically as follows:

[0063] Mode 1: It means that a transmission is provided for execution across different time slots, and the transmission is only allowed in the SBFD symbols in the SBFD time slots or in the non-SBFD symbols in the non-SBFD time slots. For example, if a transmission is only restricted to the SBFD symbols in the SBFD time slots, then all transmissions of this transmission (including retransmissions and periodic transmissions) can only be in the SBFD symbols in the SBFD time slots. For example, if a transmission is only restricted to the non-SBFD symbols in the non-SBFD time slots, then all transmissions of this transmission (including retransmissions and periodic transmissions) can only be in the non-SBFD symbols in the non-SBFD time slots.

[0064] Mode 2: It means that a transmission is provided for execution across different time slots, and the transmission is allowed in the SBFD symbols in the SBFD time slots and in the non-SBFD symbols in the non-SBFD time slots. For example, one transmission (including periodic transmission and retransmission) of a transmission is in the SBFD symbols of slot n, and another transmission of this transmission is in the non-SBFD symbols of slot m.

[0065] Wherein, the above-mentioned transmissions include downlink (DL) transmissions and uplink (UL) transmissions.

[0066] The above DL transmissions include but are not limited to at least one of the following: Physical Downlink Shared Channel (PDSCH) without repetition scheduled by Downlink Control Information (DCI), PDSCH with repetition scheduled by DCI, periodic PDSCH without repetition (such as semi-persistent scheduling Physical Downlink Shared Channel (SPS PDSCH)), periodic PDSCH with repetition, multiple PDSCHs (without repetition) scheduled by a single DCI, multiple PDSCHs (with repetition) scheduled by a single DCI, Channel State Information Reference Signal (CSI RS), Downlink Positioning Reference Signal (DL PRS).

[0067] The above UL transmission includes but is not limited to at least one of the following: Physical Uplink Shared Channel (PUSCH) without repetition scheduled by DCI (additionally including SP CSI PUSCH (semi-persistent channel state information PUSCH on the physical uplink shared channel)), PUSCH with repetition scheduled by DCI (additionally including SP CSI PUSCH), periodic PUSCH without repetition (such as type 2CG PUSCH (PUSCH of configured grant type 2), type 1CG PUSCH (PUSCH of configured grant type 1), SP CSI PUSCH, etc.), periodic PUSCH with repetition (such as type 2CG PUSCH, type 1CG PUSCH, SP CSI PUSCH, etc.), TBoMS (multi-slot data transmission, with or without repetition), PUCCH without repetition (including P / SP CSI PUCCH, SR PUCCH (PUCCH for scheduling request), HARQ-ACK PUCCH (PUCCH for hybrid automatic repeat request acknowledgment)), PUCCH with repetition (including CSI PUCCH, SR PUCCH, HARQ-ACK PUCCH), SRS.

[0068] TBoMS means that a TB is transmitted across multiple slots, that is, the data corresponding to a TB is divided into n parts and transmitted in n slots respectively.

[0069] Then, if the UL transmission is configured as mode 2, the corresponding resources in SBFD symbols and non-SBFD symbols need to be determined separately for this UL transmission. To this end, the resources allocated to the UL transmission in SBFD symbols and non-SBFD symbols can be determined according to the method provided in the following embodiments.

[0070] Figure 4 It is a schematic flowchart of a resource determination method provided by an embodiment of this application. As Figure 4 shown, the method includes:

[0071] S401. In response to mode 2 being provided for UL transmission and the resources of the UL transmission in non-SBFD symbols being provided, determine the resources allocated to the UL transmission in SBFD symbols according to the resources allocated to the UL transmission in non-SBFD symbols and the configuration information of the UL sub-bands in SBFD symbols.

[0072] Among them, the resources allocated for UL transmission in non-SBFD symbols can be determined based on the frequency-domain resource allocation field (FDRA) in DCI or RRC, and based on the resources in the non-SBFD symbol and the configuration information of the UL subbands in the SBFD symbol, determine the resources for the UL transmission in the SBFD symbol. The configuration information of the UL subbands in the SBFD symbol can include at least one of the following: the index of the lowest PRB among the UL available PRBs in the SBFD symbol (or in the UL subband), the total number of PRBs of the UL available PRBs in the SBFD symbol (or in the UL subband), and the index of the highest PRB among the UL available PRBs in the SBFD symbol (or in the UL subband).

[0073] For ease of description, relevant parameters can be described as follows:

[0074] PRB nonSBFDstarting represents the index of the lowest PRB among the PRBs allocated in the non-SBFD symbol;

[0075] N represents the number of PRBs allocated in the non-SBFD symbol;

[0076] S ULsubband represents the index of the lowest PRB among the UL available PRBs in the SBFD symbol;

[0077] N ULsubband represents the total number of PRBs of the UL available PRBs in the SBFD symbol;

[0078] E ULsubband represents the index of the highest PRB among the UL available PRBs in the SBFD symbol;

[0079] 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;

[0080] N ULBWP represents the number of PRBs corresponding to the bandwidth of the UL BWP in the non-SBFD symbol;

[0081] PRB SBFDstarting represents the index of the lowest PRB allocated for the UL transmission in the SBFD symbol.

[0082] It should be noted that N ULsubbandIt can be replaced by the difference between the maximum index and the minimum index of the UL available PRBs (or UL sub-bands) plus 1. That is, there is an association relationship between the number of PRBs in the UL available PRBs (or UL sub-bands) and the maximum PRB index. Therefore, based on this association relationship, an equivalent replacement can be set. This replacement principle also applies to other related parameters. If the index of the lowest PRB in the UL available PRBs (or UL sub-bands) in the SBFD symbol is 0, the above parameter S ULsubband may not be required either.

[0083] The above UL available PRBs refer to the PRBs in the intersection of the UL sub-band and the UL BWP in the frequency domain in the SBFD symbol.

[0084] Optionally, in the UL available PRBs (or PRBs in the UL sub-band) in the SBFD symbol and the PRBs of the UL BWP in the non-SBFD symbol, the same PRB has the same index. That is, the PRBs in the UL available PRBs (or UL sub-band) in the SBFD symbol follow the index of the corresponding PRB in the UL BWP.

[0085] Optionally, the UL transmission is allocated the same number of PRBs in the SBFD symbol and the non-SBFD symbol.

[0086] Optionally, 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 sub-band in the SBFD symbol may include one of the following methods:

[0087] Method 1: According to PRB nonSBFDstarting 、S ULsubband 、N ULsubband ,E ULsubband and at least one of offset, determine PRB SBFDstarting .

[0088] In some optional implementation manners, the modulo operation can be performed on N nonSBFDstarting using the sum result of PRB ULsubband and offset, and PRB ULsubband is determined according to the modulo operation result and S SBFDstarting .

[0089] Method 2: According to PRB nonSBFDstarting 、N、S ULsubband 、N ULsubband and at least one of offset, determine PRB SBFDstarting .

[0090] In some optional implementation manners, N ULsubbandSubtract the target number of PRBs to obtain the remaining number of PRBs; use the PRB nonSBFDstarting to perform a modulo operation on the remaining number of PRBs, and determine the PRB ULsubband according to the modulo operation result and S SBFDstarting ; where the target number is less than or equal to N.

[0091] Method 3: Determine the PRB nonSBFDstarting based on at least one of PRB ULBWP , N ULsubband , S ULsubband and N SBFDstarting .

[0092] In some optional implementation manners, the PRB nonSBFDstarting can be determined according to the multiplication result of the first ratio and the PRB ULsubband , and S SBFDstarting ; where the first ratio is the ratio between N ULsubband and N ULBWP .

[0093] Optionally, the above offset can be defaulted, or the offset is 0. Optionally, if the offset is used, the value of the offset is pre-defined or signaled-configured.

[0094] Optionally, in the case that the resources allocated to the UL transmission in the SBFD symbol determined based on the above method exceed the range of the UL available PRBs in the SBFD symbol, adjust the obtained PRB SBFDstarting . The specific adjustment method can be: reduce the PRB SBFDstarting until it satisfies that there are or exceed N consecutive PRBs from the reduced PRB SBFDstarting to E ULsubband , and determine the reduced PRB SBFDstarting as the target PRB SBFDstarting allocated to the UL transmission in the SBFD symbol, where the target PRB SBFDstarting is determined based on E ULsubband and N.

[0095] Next, specifically introduce the process of determining the resources allocated to the UL transmission in the SBFD symbol:

[0096] For the convenience of description, make the following assumptions for subsequent examples.

[0097] Hypothesis 1: The number of PRBs of the UL available PRBs (or UL sub - bands) in the SBFD symbol is 50, with the index ranging from 10 - 59 (assuming here that the minimum PRB index of the UL available PRBs or UL sub - bands is non - zero). The number of PRBs corresponding to the UL BWP in the non - SBFD symbol is 200, with the index ranging from 0 - 199. The base station allocates 40 consecutive PRBs in the non - SBFD symbol for this UL transmission, with the corresponding index being 139 - 178.

[0098] Method 1

[0099] If mode 2 is provided for UL transmission, and a frequency - domain resource allocation parameter is used to provide resources (i.e., PRBs, assuming the index of the lowest PRB among the PRBs allocated for UL transmission in the non - SBFD symbol is PRB nonSBFDstarting , and N consecutive PRBs are allocated), then the resources allocated for this 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 UL transmission is allocated the same number of PRBs in the SBFD symbol and the non - SBFD symbol.

[0100] Optionally, the frequency - domain resources allocated for the UL transmission in the UL available PRBs of the SBFD symbol can be determined by the following equation 1:

[0101] PRB SBFDstarting = S ULsubband +(PRB nonSBFDstarting + offset) mod N ULsubband Equation 1

[0102] Where, mod represents the modulo operation. For example, a mod b = c indicates that the remainder of a divided by b is c.

[0103] After obtaining PRB SBFDstarting , in the UL available PRBs of the SBFD symbol, N consecutive PRBs starting from the PRB with index PRB SBFDstarting (including) are determined as the PRBs allocated for this UL transmission in the UL available PRBs of the SBFD symbol.

[0104] Among them, offset is optional. If offset is used, the value of offset can be predefined or configured by signaling.

[0105] If the starting PRB index of the UL available PRBs (or UL sub-bands) in the SBFD symbol is 0, the above S ULsubband may not be required. Moreover, in the UL available PRBs in the SBFD symbol (or the PRBs in the UL sub-band) and in the PRBs of the ULBWP in the non-SBFD symbol, the same PRB has the same index. That is to say, the PRB in the UL available PRBs (or UL sub-band) follows the index of the corresponding PRB in the ULBWP.

[0106] However, based on the above Equation 1, the PRBs allocated for UL transmission in the SBFD symbol may exceed the range of the UL available PRBs. For example, based on the above Assumption 1, the indexes of the PRBs determined in the SBFD symbol by Equation 1 (assuming no offset) are: 49 - 88. The specific process is: PRB SBFDstarting = 10 + 139 mod 50 = 49, and then, 40 consecutive PRBs are allocated. In this way, the indexes of the PRBs allocated in the SBFD symbol are: 49 - 88, while the range of the indexes of the UL available PRBs in the SBFD symbol is 10 - 59. Therefore, if the PRBs allocated by the base station for this UL transmission in the non-SBFD symbol are inappropriate, the PRBs determined in the UL available PRBs of the SBFD symbol based on Equation 1 are also inappropriate. So, if Equation 1 is used, the UE expects that the PRBs obtained based on Equation 1 are all within the UL available PRBs (or UL sub-band) of the SBFD symbol. That is to say, the base station needs to ensure that the PRBs obtained based on Equation 1 are all within the UL available PRBs (or UL sub-band) of the SBFD symbol, thus introducing additional restrictions on the resource allocation of the base station.

[0107] For this situation, Equation 1 can be further improved. The improvement idea is: reduce the PRB SBFDstarting until it satisfies that there are or more than N consecutive PRBs from the reduced PRB SBFDstarting to E ULsubband . Then, the reduced PRB SBFDstarting is determined as the target PRB SBFDstarting allocated for UL transmission in the SBFD symbol, where the target PRB SBFDstarting is determined based on E ULsubband and N.

[0108] Specifically, first determine the PRB SBFDstarting based on Equation 1. If (PRB SBFDstarting + N - 1)> E ULsubband , then adjust the PRB SBFDstarting according to the following adjustment method 1:

[0109] PRBSBFDstarting =PRB SBFDstarting -(PRB SBFDstarting +N - 1 - E ULsubband ) = E ULsubband -N + 1.

[0110] If (PRB SBFDstarting +N - 1) ≤ E ULsubband , do not adjust PRB SBFDstarting (still determine PRB based on Equation 1 SBFDstarting ).

[0111] Among them, if there is no "1" in the above - mentioned inequality or equation, it will be difficult to allocate the maximum index PRB in the UL available PRBs. "1" can also be defaulted, that is, it does not exist, that is, it is not needed. "1" can also be replaced by other constants. Or, if the PRB SBFDstarting corresponding PRB is not included in the continuous N PRBs, that is, if the allocated continuous N PRBs start from the PRB SBFDstarting +1 corresponding PRB, then "1" can also be not needed.

[0112] This adjustment process is determined by the inequality established by N, E ULsubband and PRB SBFDstarting (PRB SBFDstarting is obtained according to Equation 1), that is, the PRB obtained from Equation 1 is adjusted by the above three parameters SBFDstarting .

[0113] Based on the above - mentioned assumption 1, through Equation 1 (assuming offset does not exist) and the above - mentioned adjustment method 1, the indexes of the PRBs determined in the SBFD symbol are: 20 - 59. The specific process is: use Equation 1 to determine PRB SBFDstarting (PRB SBFDstarting =10 + 139 mod 50 = 49), then, since (49 + 40 - 1)>59, so, based on the above - mentioned adjustment method 1, adjust PRB SBFDstarting , and the adjusted PRB SBFDstarting (that is, the adjusted PRB SBFDstarting =59 - 40 + 1 = 20), then 40 consecutive PRBs are allocated. In this way, the indexes of the allocated PRBs in the SBFD symbol are: 20 - 59.

[0114] The above - mentioned adjustment method is only an example. Based on mathematical principles, there are various deformed forms for the adjustment of PRB SBFDstarting . The following are several examples, but not limited to the following examples.

[0115] For example 1: 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., still determine PRB according to Equation 1 SBFDstarting ).

[0116] Example 2:

[0117] 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 determine PRB according to Equation 1 SBFDstarting ).

[0118] In the above adjustment examples, "1" can also be defaulted, that is, it does not exist, that is, it is not needed, and "1" can also be replaced by other constants.

[0119] According to mathematical principles, the above Equation 1 and adjustment method 1 can be transformed into:

[0120]

[0121] Or,

[0122]

[0123] where offset is optional. If offset is used, the value of offset can be predefined or configured by signaling.

[0124] Among them, if there is no "1" in the above inequality or equation, it will be difficult to allocate the maximum index PRB in the UL available PRBs. "1" can also be defaulted, that is, it does not exist, that is, it is not needed, and "1" can also be replaced by other constants. Or, if PRB SBFDstarting corresponding PRB is not included in the continuous N PRBs, that is, if the allocated continuous N PRBs start from the PRB SBFDstarting + 1 corresponding PRB, then "1" may not be needed either.

[0125] Method 2:

[0126] If Mode 2 is provided for UL transmission and a frequency-domain resource allocation parameter is used to provide resources for UL transmission in non-SBFD symbols (in the UL BWP) (i.e., PRBs, assuming the index of the lowest PRB among the PRBs allocated for UL transmission in non-SBFD symbols is PRB nonSBFDstarting , and N consecutive PRBs are allocated), then the resources allocated for this UL transmission in SBFD symbols can be determined by at least one of the following parameters: PRB nonSBFDstarting , N, S ULsubband , N ULsubband , offset. Optionally, the same number of PRBs are allocated for UL transmission in SBFD symbols and non-SBFD symbols.

[0127] Optionally, the resources allocated for this UL transmission in SBFD symbols can be determined by the following process: Subtract the target number of PRBs from N ULsubband to obtain the remaining number of PRBs (the target number is less than or equal to N); perform a modulo operation on the remaining number of PRBs using PRB nonSBFDstarting and determine PRB ULsubband according to the modulo operation result and S SBFDstarting .

[0128] Optionally, the frequency-domain resources allocated for UL transmission in the available UL PRBs (or UL subbands) of SBFD symbols can be determined based on Equation 2 below:

[0129] PRB SBFDstarting = PRB nonSBFDstarting mod (N ULsubband - N) + S ULsubband Equation 2

[0130] Optionally, the frequency-domain resources allocated for UL transmission in the available UL PRBs (or UL subbands) of SBFD symbols can also be determined based on any one of Equations 3 - 7 below:

[0131] PRB SBFDstarting = PRB nonSBFDstarting mod (N ULsubband - N) + S ULsubband + 1 Equation 3

[0132] PRB SBFDstarting = (PRB nonSBFDstarting + offset) mod (N ULsubband - N) + S ULsubband + 1 Equation 4

[0133] PRB SBFDstarting = PRB nonSBFDstarting mod (NULsubband -(N - 1)) + S ULsubband Equation 5

[0134] (After Equation 5 is simplified: PRB SBFDstarting = PRB nonSBFDstarting mod(N ULsubband – N + 1) + S ULsubband )

[0135] PRB SBFDstarting = (PRB nonSBFDstarting + offset) mod(N ULsubband -(N - 1)) + S ULsubband ; Equation 6

[0136] PRB SBFDstarting = PRB nonSBFDstarting mod(N ULsubband -(N - 1)) + S ULsubband + 1; Equation 7

[0137] After obtaining PRB SBFDstarting , among the UL available PRBs of the SBFD symbol, starting from the PRB with index PRB SBFDstarting (including), N consecutive PRBs are determined as the PRBs allocated for this UL transmission among the UL available PRBs of the SBFD symbol.

[0138] If there is no "1" in the above equation, it will make it difficult to allocate the maximum index PRB among the UL available PRBs of the SBFD symbol. "1" can also be defaulted, that is, it does not exist, that is, it is not needed. "1" can also be replaced by other constants. Or, if the PRB SBFDstarting corresponding PRB is not included in the N consecutive PRBs, that is, if the N consecutive allocated PRBs start from the PRB corresponding to PRB SBFDstarting + 1, then "1" is not needed either.

[0139] The above offset is optional. If the offset is used, the value of the offset can be predefined or configured by signaling.

[0140] And, the starting PRB index of the UL available PRB (or UL sub - band) in the SBFD symbol is 0, and this S ULsubband can be not needed. And, among the PRBs of the UL available PRBs (or PRBs in the UL sub - band) in the SBFD symbol and the PRBs of the UL BWP in the non - SBFD symbol, the same PRB has the same index. That is to say, the PRBs in the UL available PRBs (or UL sub - band) of the SBFD symbol follow the index of the corresponding PRB in the UL BWP.

[0141] Based on the above assumption 1, through Equation 2 (assuming no offset), the indexes of the PRBs determined in the SBFD symbol are: 19 - 58. The specific process is as follows: Use Equation 2 to determine the PRB SBFDstarting (PRB SBFDstarting = 139 mod (50 - 40) + 10 = 19), so, starting from the PRB with index 19 (inclusive), 40 consecutive PRBs are allocated. Thus, the indexes of the PRBs allocated in the SBFD symbol are: 19 - 58.

[0142] Based on the above assumption 1, through Equation 3 (assuming no offset), the indexes of the PRBs determined in the SBFD symbol are: 20 - 59. The specific process is as follows: Use Equation 3 to determine the PRB SBFDstarting (PRB SBFDstarting = 139 mod (50 - 40) + 10 + 1 = 20), so, starting from the PRB with index 20 (inclusive), 40 consecutive PRBs are allocated. Thus, the indexes of the PRBs allocated in the SBFD symbol are: 20 - 59.

[0143] Based on the above assumption 1, through Equation 5 (assuming no offset), the indexes of the PRBs determined in the SBFD symbol are: 17 - 56. The specific process is as follows: Use Equation 5 to determine the PRB SBFDstarting (PRB SBFDstarting = 139 mod (50 - (40 - 1)) + 10 = 17), so, starting from the PRB with index 17 (inclusive), 40 consecutive PRBs are allocated. Thus, the indexes of the PRBs allocated in the SBFD symbol are: 17 - 56.

[0144] If the indexes of the PRBs allocated in the non - SBFD symbol of assumption 1 are modified to: 131 - 170, then through Equation 5 (assuming no offset), the indexes of the PRBs determined in the SBFD symbol are: 20 - 59. The specific process is as follows: Use Equation 5 to determine the PRB SBFDstarting (PRB SBFDstarting = 131 mod (50 - (40 - 1)) + 10 = 20), so, starting from the PRB with index 20 (inclusive), 40 consecutive PRBs are allocated. Thus, the indexes of the PRBs allocated in the SBFD symbol are: 20 - 59.

[0145] For Method 1 and Method 2, if Mode 2 is provided for UL transmission, the UE does not expect (N ULsubband-(N) is less than 0, that is, the UE does not expect the number of available UL PRBs to be less than the number of PRBs allocated for UL transmission in non-SBFD symbols. That is to say, the maximum number of PRBs that the base station can allocate is equal to the number of available UL PRBs (or UL subbands).

[0146] Method 3

[0147] If Mode 2 is provided for UL transmission and a frequency-domain resource allocation parameter is used to provide resources for UL transmission in non-SBFD symbols (in the UL BWP) (i.e., PRBs, assuming the index of the lowest PRB among the PRBs allocated for UL transmission in non-SBFD symbols is PRB nonSBFDstarting , and N consecutive PRBs are allocated), then the resources allocated for this UL transmission in SBFD symbols can be determined by at least one of the following parameters: PRB nonSBFDstarting , N ULBWP , S ULsubband , and N ULsubband . Optionally, the same number of PRBs is allocated for UL transmission in SBFD symbols and non-SBFD symbols.

[0148] Optionally, the frequency-domain resources allocated for UL transmission in the available UL PRBs of SBFD symbols can be determined by Equation 8 or Equation 9 below:

[0149]

[0150] After obtaining PRB SBFDstarting , among the available UL PRBs of SBFD symbols, starting from the PRB with index PRB SBFDstarting (including), N consecutive PRBs are determined as the PRBs allocated for this UL transmission in the available UL PRBs of SBFD symbols.

[0151] If the starting PRB index of the available UL PRB (or UL subband) in SBFD symbols is 0, the above S ULsubband may not be required. And in the available UL PRBs (or PRBs in UL subbands) of SBFD symbols and the PRBs of the UL BWP in non-SBFD symbols, the same PRB has the same index. That is to say, the PRB in the available UL PRBs (or UL subbands) follows the index of the corresponding PRB in the UL BWP.

[0152] However, the PRBs allocated for UL transmission in SBFD symbols obtained based on Equation 8 or Equation 9 above may exceed the range of available UL PRBs. For this situation, Equation 8 or Equation 9 can be further improved. The improvement idea is: make PRB SBFDstartingDecrease until it meets the requirement from the decreased PRB SBFDstarting starting from to E ULsubband until there are or exceed N consecutive PRBs in between, and determine the decreased PRB SBFDstarting as the target PRB assigned to the UL transmission in the SBFD symbol SBFDstarting , where the target PRB SBFDstarting is determined based on E ULsubband and N.

[0153] Specifically, first determine the PRB 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 :

[0154] PRB SBFDstarting =PRB SBFDstarting -(PRB SBFDstarting +N-1-E ULsubband )=E ULsubband -N+1.

[0155] If (PRB SBFDstarting +N-1)≤E ULsubband , do not adjust the PRB SBFDstarting (still determine the PRB based on Equation 8 or Equation 9 SBFDstarting ).

[0156] Among them, if there is no "1" in the above inequality or equation that makes it difficult to allocate the largest index PRB among the UL available PRBs, "1" can also be omitted, that is, it does not exist, that is, it is not needed, and "1" can also be replaced by other constants. Or, if the PRB SBFDstarting corresponding PRB is not included in the consecutive N PRBs, that is, if the consecutive N PRBs allocated start from the PRB SBFDstarting +1 corresponding PRB, then "1" may not be needed either.

[0157] This adjustment process is determined based on the inequality established by N, E ULsubband and PRB SBFDstarting (PRB SBFDstarting is obtained according to Equation 8 or Equation 9), that is, adjust the PRB obtained from Equation 8 or Equation 9 through the above three parameters SBFDstarting .

[0158] Based on the above assumption 1, through Equation 8 (assuming offset does not exist) and the above adjustment method 2, the indexes of the PRBs determined in the SBFD symbol are: 20 - 59. The specific process is: use Equation 8 to determine the PRB SBFDstarting Then, since (45 + 40 - 1) > 59, the PRB is adjusted according to the above adjustment method 2 SBFDstarting (The adjusted PRB SBFDstarting = 59 - 40 + 1 = 20), and then 40 consecutive PRBs are allocated. In this way, the index of the PRBs allocated for UL transmission in the SBFD symbol is determined as: 20 - 59.

[0159] Based on the above assumption 1, through Equation 9 (assuming the offset does not exist) and the above adjustment method 2, the index of the PRBs determined in the SBFD symbol is: 20 - 59. The specific process is: use Equation 9 to determine the PRB SBFDstarting Then, since (44 + 40 - 1) > 59, the PRB is adjusted according to the above adjustment method 2 SBFDstarting (The adjusted PRB SBFDstarting = 59 - 40 + 1 = 20), and then 40 consecutive PRBs are allocated. In this way, the index of the PRBs allocated for UL transmission in the SBFD symbol is determined as: 20 - 59.

[0160] The above adjustment method is only an example. Based on mathematical principles, there are various deformed forms for the adjustment of the PRB SBFDstarting . Several examples are given below, but it is not limited to the following examples.

[0161] For example 1: If the PRB SBFDstarting >(E ULsubband - N + 1), then the PRB SBFDstarting = the PRB SBFDstarting - (the PRB SBFDstarting + N - E ULsubband - 1) = E ULsubband - N + 1; otherwise, the PRB SBFDstarting is not adjusted (i.e., still determine the PRB according to Equation 8 or Equation 9 SBFDstarting ).

[0162] If (E ULsubband - the PRB SBFDstarting + 1) < N, then the PRB SBFDstarting = the PRB SBFDstarting - (the PRB SBFDstarting + N - E ULsubband - 1) = E ULsubband - N + 1; otherwise, the PRB SBFDstarting is not adjusted (i.e., still determine the PRB according to Equation 8 or Equation 9 SBFDstarting ).

[0163] In the above adjustment examples, the "1" can also be absent, that is, it is not needed, and the "1" can also be replaced by other constants.

[0164] According to mathematical principles, the above Equation 1 and adjustment method 2 can be transformed into:

[0165]

[0166] Or,

[0167]

[0168] Or,

[0169]

[0170] Or,

[0171]

[0172] Among them, offset is optional. If offset is used, the value of offset can be predefined or configured by signaling.

[0173] Among them, if there is no "1" in the above inequality or equation, it will be difficult to allocate the maximum index PRB among the available PRBs for UL. "1" can also be defaulted, that is, it does not exist, that is, it is not needed, and "1" can also be replaced by other constants. Or, if the PRB SBFDstarting The corresponding PRB is not included in the consecutive N PRBs, that is, if the allocated consecutive N PRBs start from the PRB SBFDstarting corresponding to +1, then "1" may not be needed either.

[0174] In some embodiments, if Mode 2 is provided for UL transmission (including periodic UL transmission, with repeated UL transmission), the frequency domain resource allocation field (FDRA) in DCI or in RRC is used to determine the PRB resources of UL transmission in non-SBFD symbols, and the methods in the above Method 1, Method 2 or Method 3 are used to determine the PRB resources of this UL transmission in SBFD symbols. Even if the first repetition (or the first period, or the first transmission of TBoMS) of this UL transmission is in an SBFD symbol, the corresponding PRB resources for this first repeated transmission are determined based on the methods in the above Method 1, Method 2 or Method 3.

[0175] For the above Method 1 and Method 3, if the base station and the UE do not need to revise the PRB using the above adjustment method 1 or adjustment method 2 SBFDstarting , the following restrictions should be ensured by the base station, or the following behaviors are agreed upon by the base station and the UE.

[0176] For example 1, the base station ensures that the PRB obtained based on the above Equation 1, Equation 8 or Equation 9 SBFDstartingAnd combined with N, such that the PRBs determined in the SBFD symbol do not exceed the range of UL available PRBs (frequency domain of UL sub-bands) in the SBFD symbol (or the PRBs determined in the SBFD symbol are always within the UL available PRBs (frequency domain of UL sub-bands) in the SBFD symbol).

[0177] Correspondingly, the behavior of the UE side:

[0178] If the UE determines that the PRBs determined for UL transmission in the SBFD symbol exceed the range of UL available PRBs (frequency domain of UL sub-bands) in the SBFD symbol, the UE discards or delays the UL transmission in that SBFD symbol. Thus, for this UE, although mode 2 is provided for UL transmission, since the obtained PRBs in the SBFD symbol are not all within the range of UL available PRBs (UL sub-bands) in the SBFD symbol, this UL transmission is actually only transmitted in non-SBFD symbols (even if the UL transmission is delayed because the positions of UL available PRBs in all SBFD symbols are the same).

[0179] Or, the UE does not expect the PRBs determined in the SBFD symbol to exceed the range of UL available PRBs (frequency domain of UL sub-bands) in the SBFD symbol.

[0180] Or, if the UE determines that the PRBs determined in the SBFD symbol exceed the range of UL available PRBs (frequency domain of UL sub-bands) in the SBFD symbol, the UE considers this as a misconfiguration and does not perform the UL transmission.

[0181] In some embodiments, if mode 1 is provided for UL transmission (including periodic UL transmission, with repeated UL transmission), and if the UL transmission is not configured for frequency hopping (optional), and the first repetition or the first period of the UL transmission is in the SBFD symbol / slot, then the UE considers determining the PRB resources of the UL transmission in the SBFD symbol 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 SBFD symbols.

[0182] Method Four

[0183] A UL transmission (including type 1 CG PUSCH, type 2 CG PUSCH, PUSCH scheduled by DCI, TBoMS transmission of PUSCH, PUSCH with repetition) is configured with an RBoffset parameter for determining the starting PRB index of the second frequency hopping, which is used to describe the number of PRBs of the interval between the starting PRB of the second frequency hopping and the starting PRB of the first frequency hopping. This RBoffset parameter can be configured by RRC signaling as an RBoffset value. Alternatively, this RBoffset parameter can be configured by RRC signaling as a set, and further use the high-order 1 bit (for example, the set contains 2 values) or 2 bits (for example, the set contains 4 values) in the frequency domain resource allocation (FDRA) field in DCI to indicate an RBoffset value from this set. In this way, based on the obtained RBoffset value, the UE can determine the starting PRB of the second frequency hopping based on the starting PRB of the first frequency hopping.

[0184] If mode 2 is provided for the UL transmission as described above, and a frequency domain resource allocation parameter is used to provide resources (i.e., PRBs) for the UL transmission in non-SBFD symbols (in the UL BWP), assuming the index of the lowest PRB among the PRBs allocated to the UL transmission in non-SBFD symbols is PRB nonSBFDstarting , and N consecutive PRBs are allocated), then the resources allocated to the UL transmission in SBFD symbols can be determined by at least one of the following parameters: based on the RBoffset of the second frequency hopping of the UL transmission, based on the 1-bit or 2-bit signaling. Optionally, the UL transmission is allocated the same number of PRBs in SBFD symbols and non-SBFD symbols.

[0185] Specifically, it includes:

[0186] The base station and the UE agree to determine the allocated PRBs in SBFD symbols according to at least one of the following:

[0187] Method 1: The RBoffset value obtained from the RBoffset set of the second frequency hopping in the above manner is directly used to determine the PRBs allocated to the UL transmission in SBFD symbols. For example, the RBoffset value is used as the direct offset between the minimum PRB (index) among the PRBs allocated in non-SBFD symbols and the minimum PRB (index) among the PRBs allocated in SBFD symbols. Obviously, based on this RBoffset value and the PRBs allocated in non-SBFD symbols (including the number and position of PRBs), the PRBs configured for SBFD symbols can be obtained.

[0188] Mode 2: If it is determined which PRBs are allocated to the UL transmission in the SBFD symbols based on the signaling of the high-order 1 bit or 2 bits in the DCI, the signaling of the 1 bit or 2 bits is used to indicate an RB offset value from an RB offset set dedicated to resource allocation between SBFD symbols and non-SBFD symbols, and the indicated RB offset value is used to determine which PRBs are allocated to the UL transmission in the SBFD symbols. Among them, the RB offset set dedicated to resource allocation between SBFD symbols and non-SBFD symbols is configured by RRC signaling, and it can include 2 RB offset values or 4 RB offset values. Note: The RB offset value includes at least one of the following definitions: The RB offset value is used to describe the offset between the smallest PRB (index) among the PRBs allocated in the SBFD symbols and the smallest PRB (index) among the PRBs allocated in the non-SBFD symbols; The RB offset value describes the smallest PRB (index) among the allocated PRBs and is the offset relative to the starting PRB (index) of the UL sub-band (or UL available PRBs) in the SBFD symbols (in this case, it can be configured that hopping between slots is enabled). Obviously, based on the RB offset value and the PRBs allocated in the non-SBFD symbols (including the number and position of the PRBs), the PRBs configured for the SBFD symbols can be obtained.

[0189] In addition to the above method, for type 1 CG PUSCH, the following method can also be directly considered to determine the PRBs allocated in the SBFD symbols. For example, an RB offset value is configured in rrc-ConfiguredUplinkGrant in the ConfiguredGrantConfig corresponding to a type 1 CG PUSCH. The RB offset value includes at least one of the following definitions: The RB offset value is used to describe the offset between the smallest PRB (index) among the PRBs allocated in the SBFD symbols and the smallest PRB (index) among the PRBs allocated in the non-SBFD symbols; The RB offset value describes the smallest PRB (index) among the allocated PRBs and is the offset relative to the starting PRB (index) of the UL sub-band (or UL available PRBs) in the SBFD symbols. Obviously, based on the RB offset value and the PRBs allocated in the non-SBFD symbols (including the number and position of the PRBs), the PRBs configured for the SBFD symbols can be obtained.

[0190] In an embodiment, the allocated PRBs are PRB resource allocations based on resource allocation type 1 or resource allocation type 0 (see TS38.214 for details). And if frequency hopping within a slot or between slots is enabled, the RBoffset values obtained by the above-mentioned method 1 or method 2 are defaulted to 0 (it can also be considered that the above-mentioned method 1 or method 2 does not need to be executed). However, the RBoffset value obtained from the RBoffset set based on the second frequency hopping is used as the offset for determining the smallest PRB (index) among the allocated PRBs in the SBFD symbol. And the allocated PRBs in the SBFD symbol obtained by the above method do not exceed the frequency domain range of the UL sub-band (UL available PRBs).

[0191] For a UL transmission, if the UL transmission is performed in the SBFD symbol and / or non-SBFD symbol, since the interference situations in the SBFD symbol and non-SBFD symbol are different, therefore, based on the unified TCI state (TCI state) architecture, the transmission parameters of the transmission in the SBFD symbol and in the non-SBFD symbol (including but not limited to PDSCH, PDCCH, CSI-RS, PUSCH, PUCCH, SRS) are determined separately, or only for UL transmissions. Among them, the transmission parameters may include at least one of the following: power control information, spatial filtering information (spatial domain filter or spatial domain transmission filter).

[0192] Figure 5 For the unified TCI state activation / deactivation MAC CE (Unified TCI States Activation / Deactivation MAC CE) in the related art, however, the control unit of the medium access control (Medium Access Control Control Element, MAC CE) cannot well distinguish between the SBFD symbol and the non-SBFD symbol. Therefore, the following embodiments provide a new structure of the MAC CE based on the unified TCI state activation / deactivation, which can indicate the transmission parameters of the transmission in the SBFD symbol and in the non-SBFD symbol, especially the power control information and the spatial filtering information.

[0193] Figure 6 It is a schematic flowchart of a method for determining transmission parameters provided by an embodiment of the present application. As Figure 6 shown, the method may include:

[0194] S601. In response to a transmission being performed in non - SBFD symbols and / or SBFD symbols, determine transmission parameters corresponding to the transmission in non - SBFD symbols or SBFD symbols based on a MAC CE.

[0195] Wherein, the MAC CE is a TCI state activation / de - activation MAC CE, or the MAC CE has a structure of a TCI state activation / de - activation MAC CE. The MAC CE includes first information, and the first information is used to indicate the symbol type associated with other parameters included in the MAC CE. The above - mentioned transmission includes one of the following: downlink transmission, uplink transmission.

[0196] That is, define a new structure with a TCI state activation / de - activation MAC CE to indicate transmission parameters corresponding to a transmission in non - SBFD symbols or SBFD symbols.

[0197] For example, the first information can be "1" or "0", indicating whether the other parameters included in the MAC CE are associated with SBFD symbols or non - SBFD symbols respectively.

[0198] Optionally, the MAC CE may further include at least one of the following other parameters:

[0199] Serving Cell ID (Serving Cell ID), which is used to identify a serving cell. That is, the MAC CE is applied to this serving cell. The Serving Cell ID can be 5 bits.

[0200] DL BWP ID (Downlink Bandwidth Part ID), which is used to identify the downlink BWP. That is, the MAC CE is applied to this DL BWP. The DL BWP ID can be 2 bits. In SBFD symbols, the DL BWP refers to the DL BWP that has an intersection with the DL sub - band in the frequency domain. That is, the transmission configuration indicator (TCI) state defined by the MAC CE is applied to DL reception in the PRBs (UL available PRBs) of the intersection of this DL BWP and the DL sub - band in the frequency domain.

[0201] The UL BWP ID (Uplink Bandwidth Part Identifier) is used to identify the uplink BWP. That is to say, this MAC CE is applied to this UL BWP. The UL BWP ID can be 2 bits. In the SBFD symbol, the UL BWP refers to the UL BWP that has an intersection with the UL sub-band in the frequency domain. That is to say, the TCI state defined by this MAC CE is applied to the UL transmission in the PRBs (UL available PRBs) at the intersection of this UL BWP and the UL sub-band in the frequency domain.

[0202] P i , which is used to indicate whether each TCI code point has multiple TCI states or a single TCI state.

[0203] The TCI state ID is used to identify a TCI state.

[0204] The CORESET Pool ID (Control Resource Set Pool) is used to identify the control resource set pool.

[0205] D / U is used to indicate whether the TCI state ID in the same octet is used for combined / downlink or uplink TCI states.

[0206] R is used to identify the reserved bit.

[0207] In the embodiments of this application, a MAC CE based on unified TCI state activation / deactivation is provided. As Figure 7 shown, the first bit in the first byte of this MAC CE is set to the first information, and the first information is used to indicate the symbol type associated with other parameters included in the MAC CE.

[0208] Among them, the CORESET Pool ID is replaced by the first information, and the positions of other parameters of the MAC CE in the MAC CE are maintained. For example, the first bit of Ooc 1 of this MAC CE is set to the first information, which means whether this MAC CE is associated with SBFD symbols or non-SBFD symbols. For example, the predefined "1" and "0" correspond to SBFD symbols / slots and non-SBFD symbols / slots respectively. Further, other parameters in this MCA CE and transmission parameters associated with other parameters are applicable to the symbol type associated with this MAC CE.

[0209] Compared with Figure 5 the MAC CE in, the MAC CE provided in the embodiments of this application (as Figure 7As shown, the CORESETPool ID is missing. In this way, the base station and the UE agree that for the case of a single transmission and receiving point (TRP), for one TRP, only the CORESET Pool ID = 0 or 1 is configured, and 0 and 1 cannot be configured simultaneously, that is, only one CORESET Pool ID is configured for a single TRP. Further, it is indicated that the TCI state in this MAC CE is applicable to all CORESETs associated with the CORESET Pool ID of 0 or 1. That is to say, the MAC CE provided by the embodiments of the present application can adapt to the scenario of a single TRP.

[0210] For the explanations of other parameters, reference can be made to the descriptions in the above embodiments, and details are not described herein again.

[0211] In one embodiment, a MAC CE based on unified TCI state activation / deactivation is further provided. As Figure 8 shown, the sixth bit in the second byte of this MAC CE is set to the first information, and the first information is used to indicate the symbol type associated with other parameters included in the MAC CE, and the positions of other parameters included in the MAC CE in the MAC CE are maintained.

[0212] For example, it is predefined that "1" and "0" correspond to SBFD symbols / slots and non-SBFD symbols / slots respectively. Further, other parameters in this MCA CE and transmission parameters associated with other parameters are all applicable to the symbol type associated with this MAC CE.

[0213] Optionally, any reserved bit in the second byte of this MAC CE can also be set to the first information to indicate the symbol type associated with other parameters included in this MAC CE. Further, other parameters in this MCA CE and transmission parameters associated with other parameters are all applicable to the symbol type associated with this MAC CE.

[0214] In this embodiment, the CORESET Pool ID is used to identify the control resource set pool and is configured by coresetPoolIndex. Further, the CORESET Pool ID is set to "1", indicating that the TCI state in this MAC CE is applicable to all CORESETs associated with the CORESET Pool ID of 1; the CORESET Pool ID is set to "0", indicating that the TCI state in this MAC CE is applicable to all CORESETs associated with the CORESET Pool ID of 0.

[0215] For the explanations of other parameters, reference can be made to the descriptions in the above embodiments, and they will not be elaborated herein.

[0216] In one embodiment, there is also provided a MAC CE based on unified TCI state activation / deactivation, as Figure 9 shown. The first bit in the first byte of this MAC CE is a reserved bit, and the first information is set at the sixth bit in the second byte of the MAC CE. Among them, the CORESET Pool ID is cancelled, and the positions of other parameters in the MAC CE are maintained.

[0217] For example, it is predefined that "1" and "0" correspond to SBFD symbols / slots and non-SBFD symbols / slots respectively. Further, other parameters in this MCA CE and transmission parameters associated with other parameters are all applicable to the symbol type associated with this MAC CE.

[0218] Optionally, any one of the reserved bits in the second byte of this MAC CE can also be set as the first information to indicate the symbol type associated with other parameters included in this MAC CE. Further, other parameters in this MCA CE and transmission parameters associated with other parameters are all applicable to the symbol type associated with this MAC CE.

[0219] Compared with Figure 5 the MAC CE in Figure 9 shown, the MAC CE provided in the embodiment of the present application (as

[0220] shown) lacks the CORESET Pool ID. In this way, it is agreed between the base station and the UE that for the case of a single TRP, for one TRP, only CORESET Pool ID = 0 or 1 is configured, and 0 and 1 cannot be configured simultaneously, that is, only one CORESET Pool ID is configured for a single TRP. Further, it indicates that the TCI state in this MAC CE is applicable to all CORESETs associated with CORESET Pool ID being 0 or 1. That is to say, the MAC CE provided in the embodiment of the present application can adapt to the scenario of a single TRP.

[0221] For a 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 two UL resources associated with the same UL resource ID, where the two UL resources are associated with non-SBFD symbols and SBFD symbols respectively. For example, one UL resource is indicated by relevant parameters and is associated with non-SBFD symbols, and the other UL resource is indicated by relevant parameters and is associated with SBFD symbols. Taking a UL transmission configured with frequency hopping (including in-slot frequency hopping or inter-slot frequency hopping) as an example, a 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 hop of one UL resource in non-SBFD symbols is indicated by the parameter startingPRB, and the starting PRB of the second frequency hop in non-SBFD symbols is indicated by the parameter secondHopPRB. The starting PRB of the first frequency hop of the other UL resource in SBFD symbols is indicated by the parameter startingPRB_2, and the starting PRB of the second frequency hop in SBFD symbols is indicated by the parameter secondHopPRB_2.

[0222] However, after mode 2 is provided for UL transmission, that is, after SBFD symbols and non-SBFD symbols are introduced, the above parameters startingPRB and secondHopPRB, or startingPRB_2 and secondHopPRB_2 may not be configured. In 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.

[0223] Figure 10 It is a schematic flowchart of a transmission method provided by an embodiment of the present application. This method is applied to the first communication node, such as Figure 10 shown, this method may include:

[0224] S1001. When a UL transmission can be performed in non-SBFD symbols and SBFD symbols and is nominally provided with the following parameters, if the UL resources configured for the UL transmission are not configured with the parameters in non-SBFD symbols and the parameters in SBFD symbols, the first communication node performs the UL transmission according to the first processing method.

[0225] S1002. If the UL resources are configured with parameters in non-SBFD symbols and the UL resources are not configured with parameters in SBFD symbols, the first communication node performs UL transmission according to the second processing method.

[0226] Among them, based on SBFD symbols and non-SBFD symbols respectively, the above parameters include at least one of the following: parameters of physical resource blocks for determining the first frequency hopping of UL transmission, parameters of physical resource blocks for determining the second frequency hopping of UL transmission, parameters for configuring frequency hopping within a time slot for UL transmission, parameters for configuring no frequency hopping within a time slot for UL transmission, parameters for configuring frequency hopping between time slots for UL transmission, parameters for configuring no frequency hopping between time slots for UL transmission, parameters for determining the physical resource blocks of UL transmission in SBFD symbols, parameters for determining the physical resource blocks of UL transmission in non-SBFD symbols.

[0227] Among them, nominally providing the following parameters means that the parameter is an optional configuration in the signaling structure, that is, the base station can not configure this parameter.

[0228] Optionally, the above frequency hopping may include frequency hopping between time slots or frequency hopping within a time slot.

[0229] Optionally, the first processing method includes one of the following:

[0230] Method 1: Perform UL transmission, and the parameters used in non-SBFD symbols are determined based on the parameters in SBFD symbols.

[0231] Taking the example where the UL transmission is configured to perform frequency hopping (frequency hopping in both SBFD symbols and non - SBFD symbols), if the starting PRBs of the first and second frequency hops of the UL resources configured for this UL transmission are not configured in non - SBFD symbols, that is, the parameters startingPRB and secondHopPRB are not configured, but the starting PRBs of the first and second frequency hops of the UL resources are configured in SBFD symbols, that is, the parameters startingPRB_2 and secondHopPRB_2 are configured, then the UE performs this UL transmission, and the starting PRBs of the first and second frequency hops used in non - SBFD symbols are determined based on the starting PRBs of the first and second frequency hops in SBFD symbols, that is, the starting PRBs of the first and second frequency hops in non - SBFD symbols are determined by the parameters startingPRB_2 and secondHopPRB_2. For example, if the parameters startingPRB and secondHopPRB associated with non - SBFD symbols are not configured for the UL resources, then the starting PRBs of the first and second frequency hops of this UL transmission in non - SBFD symbols are determined by the parameters startingPRB_2 and secondHopPRB_2. This is because the starting PRBs of the first and second frequency hops of this UL transmission obtained based on the parameters startingPRB_2 and secondHopPRB_2 associated with SBFD symbols must be within the UL BWP in non - SBFD symbols, that is, the resources corresponding to the first and second frequency hops in non - SBFD symbols are valid.

[0232] Method 2: Perform UL transmission, and the UL resources used in non - SBFD symbols are the same as those used in SBFD symbols, and the UL resources used in non - SBFD symbols are determined based on the parameters in SBFD symbols.

[0233] Taking the example where the UL transmission is configured to perform frequency hopping (frequency hopping in both SBFD symbols and non - SBFD symbols), if the starting PRBs of the first and second frequency hops of the UL resources are not configured in non - SBFD symbols, that is, the parameters startingPRB and secondHopPRB are not configured, but the starting PRBs of the first and second frequency hops of the UL resource ID are configured in SBFD symbols, that is, the parameters startingPRB_2 and secondHopPRB_2 are configured, then the UE performs this UL transmission, and the UL resources used in non - SBFD symbols are the same as those used in SBFD symbols, that is, both are determined by the parameters startingPRB_2 and secondHopPRB_2.

[0234] Optionally, the above second processing method includes one of the following:

[0235] Method 1: Perform UL transmission, and the UL resources used in SBFD symbols are the same as those used in non-SBFD symbols, and the UL resources used in SBFD symbols are determined based on the parameters in non-SBFD symbols.

[0236] Taking frequency hopping as an example, if the UL resources are configured at the starting PRBs of the first and second frequency hops in non-SBFD symbols, that is, the parameters startingPRB and secondHopPRB are configured, but the UL resources are not configured at the starting PRBs of the first and second frequency hops in SBFD symbols, that is, the parameters startingPRB_2 and secondHopPRB_2 are not configured, then the UE performs the UL transmission, and the UL resources used in SBFD symbols are the same as those used in non-SBFD symbols, that is, both are determined by the parameters startingPRB and secondHopPRB.

[0237] Method 2: Perform UL transmission, and the UL resources used in SBFD symbols are the same as those used in non-SBFD symbols, and the UL resources used in SBFD symbols are determined based on the parameters in non-SBFD symbols, and the first communication node expects / requires that the UL resources determined based on the parameters in non-SBFD symbols are valid in SBFD symbols.

[0238] Taking frequency hopping as an example, if the UL resources are configured at the starting PRBs of the first and second frequency hops in non-SBFD symbols, that is, the parameters startingPRB and secondHopPRB are configured, but the UL resources are not configured at the starting PRBs of the first and second frequency hops in SBFD symbols, that is, the parameters startingPRB_2 and secondHopPRB_2 are not configured, then the UE performs the UL transmission, and the UL resources used in SBFD symbols are the same as those used in non-SBFD symbols, that is, both are determined by the parameters startingPRB and secondHopPRB, and the first communication node expects / requires that the UL resources are valid in SBFD symbols (that is, the UL resources are within the UL available PRBs or UL subbands).

[0239] Method 3: If the UL resource determined based on the parameters in the non-SBFD symbol is valid in the SBFD symbol, perform 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 parameters in the non-SBFD symbol.

[0240] Continuing with the example of frequency hopping, if the UL resource determined by the parameters startingPRB and secondHopPRB is valid in the SBFD symbol (i.e., the UL resource is within the UL available PRBs or UL subbands), 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, that is, both are determined by the parameters startingPRB and secondHopPRB.

[0241] Method 4: If the UL resource determined based on the parameters in the non-SBFD symbol is invalid in the SBFD symbol, perform UL transmission only in the non-SBFD symbol.

[0242] That is to say, 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 within the range of the UL available PRBs or UL subbands), even if the above-mentioned mode 2 is provided for the UL transmission, the first communication node performs the UL transmission only in the non-SBFD symbol.

[0243] Method 5: Perform UL transmission in the SBFD symbol without performing frequency hopping, and perform UL transmission in the non-SBFD symbol with frequency hopping.

[0244] Method 6: Perform UL transmission in the SBFD symbol without performing frequency hopping, and perform UL transmission in the non-SBFD symbol without performing frequency hopping.

[0245] Figure 11 Another process schematic diagram of the transmission method provided by the embodiments of this application. This method is applied to the second communication node, as Figure 11 shown, this method may include:

[0246] S1101: When a UL transmission can be performed in both non-SBFD symbols and SBFD symbols and the following parameters are nominally provided, if the UL resource configured for the UL transmission is not configured with the parameters in the non-SBFD symbol and the UL resource is configured with the parameters in the SBFD symbol, the second communication node receives the UL transmission according to the first processing method.

[0247] S1102. If the parameters of the UL resources are configured in non-SBFD symbols and the parameters of the UL resources are not configured in SBFD symbols, the second communication node receives the UL transmission according to the second processing method.

[0248] Among them, based on SBFD symbols and non-SBFD symbols respectively, the parameters include at least one of the following: parameters for determining the physical resource blocks of the first frequency hopping of the UL transmission, parameters for determining the physical resource blocks of the second frequency hopping of the UL transmission, parameters for configuring frequency hopping within the time slots for the UL transmission to be performed, parameters for configuring no frequency hopping within the time slots for the UL transmission, parameters for configuring frequency hopping between the time slots for the UL transmission to be performed, parameters for configuring no frequency hopping between the time slots for the UL transmission, parameters for determining the physical resource blocks of the UL transmission in SBFD symbols, and parameters for determining the physical resource blocks of the UL transmission in non-SBFD symbols.

[0249] Among them, nominally providing the following parameters means that this parameter is an optional configuration in the signaling structure, that is, the base station may not configure this parameter.

[0250] Optionally, the above first processing method includes one of the following:

[0251] Method 1: Receive the UL transmission, and the parameters used in non-SBFD symbols are determined based on the parameters in SBFD symbols.

[0252] Method 2: Receive the UL transmission, and the UL resources used in non-SBFD symbols are the same as the UL resources used in SBFD symbols, and the UL resources used in non-SBFD symbols are determined based on the parameters in SBFD symbols.

[0253] Optionally, the above second processing method includes one of the following:

[0254] Method 1: Receive the UL transmission, and the UL resources used in SBFD symbols are the same as the UL resources used in non-SBFD symbols, and the UL resources used in SBFD symbols are determined based on the parameters in non-SBFD symbols.

[0255] Method 2: Receive the UL transmission, and the UL resources used in SBFD symbols are the same as the UL resources used in non-SBFD symbols, and the UL resources used in SBFD symbols are determined based on the parameters in non-SBFD symbols, and the second communication node ensures that the UL resources determined based on the parameters in non-SBFD symbols are valid in SBFD symbols.

[0256] Mode 3: If the UL resources determined based on the parameters in the non-SBFD symbol are valid in the SBFD symbol, receive the UL transmission, and the UL resources used in the SBFD symbol are the same as those 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.

[0257] Mode 4: If the UL resources determined based on the parameters in the non-SBFD symbol are invalid in the SBFD symbol, receive the UL transmission only in the non-SBFD symbol.

[0258] Mode 5: Receive the UL transmission in the SBFD symbol without frequency hopping, and receive the UL transmission in the non-SBFD symbol with frequency hopping.

[0259] Mode 6: Receive the UL transmission in the SBFD symbol without frequency hopping, and receive the UL transmission in the non-SBFD symbol without frequency hopping.

[0260] Exemplarily, taking a transmission as a PUSCH transmission as an example, a PUSCH transmission can be configured / provided with RB offsets for the SBFD symbol and the non-SBFD symbol (denoted as RBoffset1 and RBoffset2 respectively, RBoffset1 is associated with the SBFD symbol, and RBoffset2 is associated with the non-SBFD symbol. Based on this independent RB offset, the corresponding PUSCH resources can be determined in the SBFD symbol and the non-SBFD symbol respectively, and the PUSCH resources are used for the frequency hopping of the PUSCH transmission). However, in some cases, the PUSCH transmission may only be configured / provided with the RB offset for the SBFD symbol or the non-SBFD symbol, that is, the PUSCH transmission is only configured with RBoffset1 for the SBFD symbol, or the PUSCH transmission is only configured with RBoffset2 for the non-SBFD symbol. Further, if the above-mentioned Mode 1 or Mode 2 is configured / provided for a PUSCH transmission, then the behaviors of the UE and the base station can be clarified according to at least one of the following methods (that is, the UE needs to clarify how to perform the PUSCH transmission, and the base station needs to clarify how to receive the PUSCH transmission).

[0261] Following the above description, for a PUSCH transmission that is not configured with the RB offset for the SBFD symbol or the non-SBFD symbol, the behaviors of the base station and the UE should consider the following options.

[0262] Option 1:

[0263] If the PUSCH transmission is not configured with an RBoffset1 for SBFD symbols, but the PUSCH transmission is configured with an RBoffset2 for non-SBFD symbols, then one of the following can be supported:

[0264] Perform frequency hopping of the PUSCH transmission in SBFD symbols by using the PUSCH resources determined by RBoffset2 for non-SBFD symbols. If part or all of the PUSCH resources are outside the UL available PRBs (or UL sub-bands), then the frequency hopping of the PUSCH transmission in SBFD symbols is cancelled, that is, the frequency hopping of the PUSCH transmission in SBFD symbols is not performed. Further, perform frequency hopping of the PUSCH transmission in non-SBFD symbols and perform frequency hopping based on the PUSCH resources determined by RBoffset2 for non-SBFD symbols.

[0265] Only perform frequency hopping of the PUSCH transmission in non-SBFD symbols and perform frequency hopping based on the PUSCH resources determined by RBoffset2 for non-SBFD symbols, that is, do not perform frequency hopping of the PUSCH transmission in SBFD symbols, for example, equivalent to the frequency hopping function being disabled in SBFD symbols.

[0266] The UE does not expect this configuration, and the base station should ensure that this configuration does not occur.

[0267] The UE considers this to be a wrong configuration and does not perform frequency hopping of the PUSCH transmission in SBFD symbols and non-SBFD symbols, that is, perform the PUSCH transmission in a non-frequency-hopping manner.

[0268] The UE ignores this configuration and does not perform the PUSCH transmission.

[0269] Option 2:

[0270] If the PUSCH transmission is not configured with an RBoffset2 for non-SBFD symbols, but the PUSCH transmission is configured with an RBoffset1 for SBFD symbols, then one of the following can be supported:

[0271] Perform frequency hopping of the PUSCH transmission in non-SBFD symbols and perform frequency hopping by using the PUSCH resources determined by RBoffset1 for SBFD symbols. Perform frequency hopping of the PUSCH transmission in SBFD symbols and perform frequency hopping by using the PUSCH resources determined by RBoffset1 for SBFD symbols.

[0272] Only perform the frequency hopping of the PUSCH transmission in the SBFD symbols, and perform the frequency hopping based on the PUSCH resources determined by RBoffset1 for the SBFD symbols, that is, do not perform the frequency hopping of the PUSCH transmission in the non-SBFD symbols, for example, it is equivalent to disabling the frequency hopping in the non-SBFD symbols.

[0273] The UE does not expect this configuration, and the base station should ensure that this configuration does not occur.

[0274] The UE considers it a wrong configuration and does not perform the frequency hopping of the PUSCH transmission in the non-SBFD symbols and SBFD symbols, that is, performs the PUSCH transmission in a non-frequency-hopping manner.

[0275] The UE ignores this configuration and does not perform the PUSCH transmission.

[0280] Among them, nominally providing the following resource parameters means that the resource parameters are optionally configured in the signaling structure, that is, the base station may not configure the resource parameters.

[0281] Optionally, the above frequency hopping includes inter-slot frequency hopping or intra-slot frequency hopping.

[0282] Optionally, the above third processing method includes one of the following:

[0283] Method 1: Perform UL transmission, and the resource parameters used in non-SBFD symbols are determined based on the resource parameters in SBFD symbols.

[0288] Method 3: If the UL resources determined based on the resource parameters in non-SBFD symbols are valid in SBFD symbols, then perform UL transmission, and the UL resources used in SBFD symbols are the same as the UL resources used in non-SBFD symbols, and the UL resources used in SBFD symbols are determined based on the resource parameters in non-SBFD symbols.

[0289] Method 4: If the UL resources determined based on the resource parameters in non-SBFD symbols are invalid in SBFD symbols, then perform UL transmission only in non-SBFD symbols.

[0290] Method 5: Perform UL transmission in SBFD symbols and do not perform frequency hopping, and perform UL transmission in non-SBFD symbols and perform frequency hopping.

[0291] Mode 6: Perform UL transmission in SBFD symbols without performing frequency hopping, and perform UL transmission in non-SBFD symbols without performing frequency hopping.

[0292] Figure 13 Another flowchart of the transmission method provided by the embodiment of the present application. This method is applied to the second communication node, such as Figure 13 As shown, the method may include:

[0293] S1301. When a UL transmission can be performed under the condition that the following resource parameters are nominally provided in non-SBFD symbols and SBFD symbols, if the UL resource ID configured for the UL transmission is not configured in the resource parameters of non-SBFD symbols and the UL resource ID is configured in the resource parameters of SBFD symbols, the second communication node receives the UL transmission according to the third processing mode.

[0294] S1302. If the UL resource ID is configured in the resource parameters of non-SBFD symbols and the UL resource ID is not configured in the resource parameters of SBFD symbols, the second communication node receives the UL transmission according to the fourth processing mode.

[0295] Wherein, based on SBFD symbols and non-SBFD symbols respectively, the resource parameters include at least one of the following: parameters of physical resource blocks for determining the first frequency hopping of UL transmission, parameters of physical resource blocks for determining the second frequency hopping of UL transmission, parameters for configuring frequency hopping within a time slot for UL transmission, parameters for configuring no frequency hopping within a time slot for UL transmission, parameters for configuring frequency hopping between time slots for UL transmission, parameters for configuring no frequency hopping between time slots for UL transmission, parameters of physical resource blocks for determining UL transmission in SBFD symbols, parameters of physical resource blocks for determining UL transmission in non-SBFD symbols, the maximum code rate for determining UL transmission in SBFD symbols, and the maximum code rate for determining UL in non-SBFD symbols.

[0296] Wherein, nominally providing the following resource parameters means that the resource parameters are optionally configured in the signaling structure, that is, the base station may not configure the resource parameters.

[0297] Optionally, the above frequency hopping includes frequency hopping between time slots or frequency hopping within a time slot.

[0298] Optionally, the above third processing mode includes one of the following:

[0299] Mode 1: Receive the UL transmission, and the resource parameters used in non-SBFD symbols are determined based on the resource parameters in SBFD symbols.

[0300] Mode 2: Receive UL transmissions, where the UL resources used in non-SBFD symbols are the same as those used in SBFD symbols, and the UL resources used in non-SBFD symbols are determined based on the resource parameters in SBFD symbols.

[0301] Optionally, the above fourth processing mode includes one of the following:

[0302] Mode 1: Receive UL transmissions, where the UL resources used in SBFD symbols are the same as those used in non-SBFD symbols, and the UL resources used in SBFD symbols are determined based on the resource parameters in non-SBFD symbols.

[0303] Mode 2: Receive UL transmissions, where the UL resources used in SBFD symbols are the same as those used in non-SBFD symbols, and the UL resources used in SBFD symbols are determined based on the resource parameters in non-SBFD symbols, and the second communication node ensures that the UL resources determined based on the parameters in non-SBFD symbols are valid in SBFD symbols.

[0304] Mode 3: If the UL resources determined based on the resource parameters in non-SBFD symbols are valid in SBFD symbols, then receive UL transmissions, where the UL resources used in SBFD symbols are the same as those used in non-SBFD symbols, and the UL resources used in SBFD symbols are determined based on the resource parameters in non-SBFD symbols.

[0306] Mode 5: Receive UL transmissions in SBFD symbols without frequency hopping, and receive UL transmissions in non-SBFD symbols with frequency hopping.

[0307] Mode 6: Receive UL transmissions in SBFD symbols without frequency hopping, and receive UL transmissions in non-SBFD symbols without frequency hopping.

[0308] Exemplarily, taking a transmission as a PUCCH transmission as an example, a pucch-ResourceId can be configured / provided for 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). However, in some cases, the pucch-ResourceId may be configured / provided only for PUCCH resources for SBFD symbols or non-SBFD symbols, that is, the pucch-ResourceId is only configured for PUCCH resource 1 for SBFD symbols, or the pucch-ResourceId is only configured for PUCCH 2 for non-SBFD symbols. Further, if the above-mentioned mode 1 or mode 2 is configured / provided for a PUCCH transmission, and the PUCCH transmission is configured to use the PUCCH resource corresponding to the pucch-ResourceId, then the base station and the UE determine their respective behaviors according to at least one of the following methods (that is, the UE needs to determine how to perform the PUCCH transmission? The base station needs to determine how to receive the PUCCH transmission?).

[0309] For a pucch-ResourceId that is not configured for a PUCCH resource for SBFD symbols or for non-SBFD symbols, if the pucch-ResourceId is configured for a PUCCH transmission, the behaviors of the base station and the UE should consider the following options.

[0310] Option 1:

[0312] Perform the PUCCH transmission in SBFD symbols, and perform the PUCCH transmission in SBFD symbols 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 the UL available PRBs (or UL sub-bands), then the PUCCH transmission in SBFD symbols is invalid, for example, discard the PUCCH transmission in SBFD symbols in the slot.

[0313] The UE does not expect this configuration, and the base station should ensure that this configuration does not occur.

[0314] The UE considers it a wrong configuration and does not perform the PUCCH transmission.

[0315] The UE ignores the configuration and does not perform the PUCCH transmission.

[0316] Option 2:

[0317] If the pucch-ResourceId is not configured for a PUCCH resource for SBFD symbols, but the pucch-ResourceId is configured for a PUCCH resource for non-SBFD symbols, and if the above-mentioned 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:

[0318] The PUCCH transmission is performed normally, that is, the PUCCH transmission in non-SBFD symbols is performed, and the PUCCH transmission is performed by using the PUCCH resource provided by the pucch-ResourceId and for non-SBFD symbols.

[0319] Option 3:

[0320] If the pucch-ResourceId is not configured for a PUCCH resource for SBFD symbols, but the pucch-ResourceId is configured for a PUCCH resource for non-SBFD symbols, and if the above-mentioned mode 2 is provided for the PUCCH transmission, then one of the following can be supported:

[0321] Perform the PUCCH transmission in SBFD symbols, and perform the PUCCH transmission in SBFD symbols 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 the UL available PRBs (or UL subbands), then the PUCCH transmission in SBFD symbols is invalid, for example, the PUCCH transmission in SBFD symbols in a slot is discarded / postponed.

[0322] Perform the PUCCH transmission only in non-SBFD symbols, and perform the PUCCH transmission in non-SBFD symbols by using the PUCCH resource of non-SBFD symbols associated with the pucch-ResourceId, that is, the UE considers the PUCCH transmission to be updated to mode 1 and performs the PUCCH transmission only in non-SBFD symbols. That is, do not perform the PUCCH transmission in SBFD symbols.

[0323] The UE does not expect such a configuration, and the base station should ensure that such a configuration does not occur.

[0324] The UE considers it a wrong configuration and does not perform the PUCCH transmission.

[0325] The UE ignores the configuration and does not perform the PUCCH transmission.

[0326] Option 4:

[0327] If the pucch-ResourceId is not configured for a PUCCH resource for non-SBFD symbols, but the pucch-ResourceId is configured for a PUCCH resource for SBFD symbols, and if the above-mentioned 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:

[0328] Perform the PUCCH transmission in non-SBFD symbols, and perform the PUCCH transmission in non-SBFD symbols 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-bands) in non-SBFD symbols, because the bandwidth of the UL BWP is greater than the bandwidth of the UL available PRBs.

[0329] The UE does not expect such a configuration, and the base station should ensure that such a configuration does not occur.

[0330] The UE considers it a wrong configuration and does not perform the PUCCH transmission.

[0331] The UE ignores the configuration and does not perform the PUCCH transmission.

[0332] Option 5:

[0333] If the pucch-ResourceId is not configured for a PUCCH resource for non-SBFD symbols, but the pucch-ResourceId is configured for a PUCCH resource for SBFD symbols, and if the above-mentioned Mode 1 is provided for 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:

[0334] The PUCCH transmission is performed normally. That is, the PUCCH transmission in the SBFD symbol is performed, and the PUCCH transmission in the SBFD symbol is performed by using the PUCCH resource provided by the pucch-ResourceId and targeted for the SBFD symbol.

[0335] Option 6:

[0336] If the pucch-ResourceId is not configured with a PUCCH resource for non-SBFD symbols, but the pucch-ResourceId is configured with a PUCCH resource for SBFD symbols, and if the above-mentioned mode 2 is provided for the PUCCH transmission, then one of the following can be supported:

[0337] Perform the PUCCH transmission in non-SBFD symbols, and perform the PUCCH transmission in non-SBFD symbols by using the PUCCH resource provided by the pucch-ResourceId and targeted for SBFD symbols. In this case, the PUCCH resource must be in the UL available PRBs (or UL sub-bands) in non-SBFD symbols, because the bandwidth of the UL BWP is greater than the bandwidth of the UL available PRBs.

[0338] Only perform the PUCCH transmission in SBFD symbols, and perform the PUCCH transmission by using the PUCCH resource of the SBFD symbol associated with the pucch-ResourceId. That is, the UE considers that the PUCCH transmission is updated to mode 1 and is only performed in SBFD symbols. That is, the PUCCH transmission is not performed in non-SBFD symbols.

[0339] The UE does not expect this configuration, and the base station should ensure that this configuration does not occur.

[0340] The UE considers it a wrong configuration and does not perform the PUCCH transmission.

[0341] The UE ignores this configuration and does not perform the PUCCH transmission.

[0342] In one embodiment, the triggering of the above-mentioned frequency hopping function is through the following parameters:

[0343] IntraSlotFrequencyHopping (intra-slot frequency hopping) is used to configure the frequency hopping of UL transmissions 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, a parameter (denoted as intraSlotFrequencyHopping_1) is provided for Mode 1 to determine whether the UL transmission based on Mode 1 hops within the slot. If the above-mentioned Configuration 2 is provided for the UE for UL transmission, another parameter (denoted as intraSlotFrequencyHopping_2) is provided for Mode 2 to determine whether the UL transmission based on Mode 2 hops within the slot. It can also be that Mode 1 and Mode 2 share the parameter intraSlotFrequencyHopping, that is, the UL transmissions based on both Mode 1 and Mode 2 determine whether to hop within the slot based on this parameter intraSlotFrequencyHopping.

[0344] InterSlotFrequencyHopping (inter-slot frequency hopping) is used to configure the frequency hopping of UL transmissions 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, a parameter (denoted as interSlotFrequencyHopping_1) is provided for Mode 1 to determine whether the UL transmission based on Mode 1 hops between slots. If the above-mentioned Mode 2 is provided for UL transmission, another parameter (denoted as interSlotFrequencyHopping_2) is provided for Mode 2 to determine whether the UL transmission based on Mode 2 hops between slots. It can also be that Mode 1 and Mode 2 share the parameter interSlotFrequencyHopping, that is, the UL transmissions based on both Mode 1 and Mode 2 determine whether to hop between slots based on this parameter intraSlotFrequencyHopping.

[0345] interSlotFrequencyHopping can also be configured separately for UL transmissions in SBFD symbols and UL transmissions in non-SBFD symbols. That is, whether UL transmission performs inter-SBFD slot hopping is based on a parameter associated with the SBFD symbol (denoted as interSlotFrequencyHopping_3), and once enabled, the inter-SBFD slot hopping of this UL transmission is performed between SBFD slots. Whether UL transmission performs inter-non-SBFD slot hopping is based on a parameter associated with the non-SBFD symbol (denoted as interSlotFrequencyHopping_4), and once enabled, the inter-non-SBFD slot hopping of this UL transmission is performed between non-SBFD slots. It can also be that a common parameter interSlotFrequencyHopping is used for UL transmissions in SBFD symbols and non-SBFD symbols to determine whether to perform inter-SBFD slot hopping, and once enabled, this UL transmission performs inter-SBFD slot hopping and inter-non-SBFD slot hopping.

[0346] In one embodiment, when Mode 2 is provided for UL transmission, that is, after SBFD symbols and non-SBFD symbols are introduced, corresponding PUCCH resources and parameters associated with the PUCCH resources need to be configured separately for SBFD symbols and non-SBFD symbols to support the transmission of PUCCH in SBFD symbols and non-SBFD symbols. Some parameter configurations associated with the PUCCH resources are provided below.

[0347] Configuration of the associated parameter PUCCH-FormatConfig for the PUCCH resource:

[0348] Solution 1:

[0349] The configuration information in this parameter PUCCH-FormatConfig is shared by the PUCCH resources associated with SBFD symbols and non-SBFD symbols.

[0350] For example, the PUCCH resource 1 corresponding to a certain PUCCH format (one of PUCCH formats 0 / 1 / 2 / 3 / 4) (assuming associated with an SBFD symbol) and the corresponding PUCCH resource 2 (associated with a non-SBFD symbol) 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.

[0351] When Scheme 1 can naturally maintain PUCCH repetition, the PUCCH transmissions in different symbol types still remain consistent.

[0352] Scheme 2:

[0353] Each of the SBFD symbol and the non-SBFD symbol is associated with a parameter PUCCH-FormatConfig.

[0354] For example, for a PUCCH resource 1 corresponding to a certain PUCCH format (one of PUCCH formats 0 / 1 / 2 / 3 / 4, assumed to be associated with an SBFD symbol) and a corresponding PUCCH resource 2 (associated with a non-SBFD symbol), the configurations in the respective PUCCH-FormatConfig parameters are used. Among them, PUCCH resource 1 and PUCCH 2 have the same pucch-ResourceId.

[0355] Scheme 2 is also reasonable because the two types of symbols face different interferences and the parameters inside may be different. However, from the perspective of PUCCH repetition, Scheme 2 cannot directly maintain the consistency of PUCCH repetition in different symbol types and requires base station configuration to ensure consistency.

[0356] It should be noted that: The above Scheme 1 and Scheme 2 also apply to each specific parameter in PUCCH-FormatConfig. For example, some parameter examples are as follows:

[0357] maxCodeRate (maximum code rate):

[0358] The base station and the UE agree that: Since the interferences faced in different symbol types are different, the maximum code rate parameter (maxCodeRate) is configured separately for different symbol types (SBFD symbol and non-SBFD symbol), specifically including:

[0359] For Scheme 1, a new parameter (such as maxCodeRate1) is added to describe the maximum code rate used for PUCCH transmission in SBFD symbols / slots; the original parameter maxCodeRate describes the maximum code rate used for PUCCH transmission in non-SBFD symbols / slots.

[0360] For Scheme 2, two values are associated with this parameter (such as maxCodeRate). One value is associated with the SBFD symbol and describes the maximum code rate used for PUCCH transmission in SBFD symbols / slots. The other value (i.e., the existing value) is associated with non-SBFD symbols / slots and describes the maximum code rate used for PUCCH transmission in non-SBFD symbols / slots;

[0361] Solution 3: The PUCCH resource 1 and the PUCCH resource 2 with the same pucch-ResourceId share the parameter maxCodeRate.

[0362] Solution 4: Based on the existing maxCodeRate parameter, an offset parameter is provided. Based on this offset, a value can be determined from the PUCCH-MaxCodeRate, and this value is used for the PUCCH resource associated with the SBFD symbol. For example, the existing maxCodeRate applies to non-SBFD symbols, and the value obtained based on this offset applies to SBFD symbols. Alternatively, this offset can be a predefined value, thus saving signaling overhead.

[0363] It should be noted that if two PUCCH resources associated with a PUCCH resource ID are respectively configured with the maxCodeRate associated with the SBFD symbol and the maxCodeRate associated with the non-SBFD symbol, and if a PUCCH transmission with repetition is triggered and the above-mentioned mode 2 is provided for this PUCCH transmission, then the maxCodeRate associated with the SBFD symbol and the maxCodeRate associated with the non-SBFD symbol are required to be configured with the same value, that is, the PUCCH resources associated with the SBFD symbol and the PUCCH resources associated with the non-SBFD symbol are required to be configured with the same following parameters: the parameters included in the PUCCH-FormatConfig and the parameters included by the PUCCH-Resource.

[0364] interslotFrequencyHopping (inter-symbol frequency hopping):

[0365] The meaning of this parameter is updated to: After this parameter is enabled, two PUCCH resources with the same pucch-ResourceId can perform frequency hopping between SBFD slots (using the above-mentioned PUCCH resource 1) and between non-SBFD slots (using the above-mentioned PUCCH resource 2).

[0366] If the frequency hopping between SBFD slots and the frequency hopping between non-SBFD slots are performed independently, then the following improvements need to be considered for this parameter:

[0367] Solution 1: Add a new parameter (e.g., interslotFrequencyHopping1) to describe the allowed frequency hopping of PUCCH between SBFD slots; the original parameter interslotFrequencyHopping describes the allowed frequency hopping of PUCCH between non-SBFD slots.

[0368] Solution 2: Associate two values with this parameter (e.g., interslotFrequencyHopping). One value describes the allowed frequency hopping of PUCCH between SBFD slots. The other value (i.e., the existing value) describes the allowed frequency hopping of PUCCH between non-SBFD slots;

[0369] Solution 3: PUCCH Resource 1 and PUCCH Resource 2 with the same pucch-ResourceId share the parameter interslotFrequencyHopping. After this parameter is enabled, PUCCH Resource 1 associated with SBFD symbols hops between SBFD slots, and PUCCH Resource 2 associated with non-SBFD symbols hops between non-SBFD slots.

[0370] It should be noted that for frequency hopping between two types of slots: For example, for two slots at the junction of two types of slots, namely SBFD slots and non-SBFD slots, the PUCCH resources used in the latter slot should maintain the maximum frequency-domain interval from the PUCCH resources used in the former slot. For example, based on maximizing the frequency-domain interval, it is determined that the starting PRB or secondHopPRB associated with this PUCCH resource is used as the starting PRB of the PUCCH resource in the latter slot.

[0371] For example, a pucch-ResourceId is associated with two PUCCH resources. The first PUCCH resource is associated with non-SBFD symbols, and the starting PRBs of the first and second frequency hops are indicated based on the parameters startingPRB and secondHopPRB respectively. The second PUCCH resource is associated with SBFD symbols, and the starting PRBs of the first and second frequency hops are indicated based on the parameters startingPRB_2 and secondHopPRB_2 respectively. After frequency hopping between slots is enabled, in two slots at the junction of SBFD slots and non-SBFD slots, assuming the former is a non-SBFD slot and the latter is an SBFD slot (vice versa), and the PUCCH resource in the former slot has been determined based on startingPRB or secondHopPRB (assuming the PUCCH resource in the former slot has been determined based on startingPRB), then the PUCCH resource in the latter slot should be determined based on the parameters startingPRB_2 or secondHopPRB_2 that maximize the frequency-domain interval between the PUCCH resource in the latter slot and the PUCCH resource in the former slot.

[0372] Configuration of the association parameter PUCCH-ResourceSet (PUCCH resource set) for PUCCH resources:

[0373] pucch-ResourceSetId (PUCCH resource set identifier):

[0374] In a PUCCH resource set corresponding to a pucch-ResourceSetId, the PUCCH resources associated with SBFD symbols are configured with a maximum of 8 PUCCH formats 2 / 3 / 4 (a maximum of 32 PUCCH formats 0 / 1), and the PUCCH resources associated with non-SBFD symbols are configured with a maximum of 8 PUCCH formats 2 / 3 / 4 (a maximum of 32 PUCCH formats 0 / 1).

[0375] That is to say, a PUCCH resource set contains both PUCCH resources associated with SBFD symbols and PUCCH resources associated with non-SBFD symbols.

[0376] That is to say, the SBFD symbols and non-SBFD symbols share the same PUCCH resource set, and a PUCCH resource set contains at most 8 PUCCH resources and each PUCCH resource has a corresponding index, and a PUCCH resource associated with an SBFD symbol and a PUCCH resource associated with a non-SBFD symbol can have the same pucch-ResourceId.

[0377] Alternatively, the SBFD symbols and non-SBFD symbols share the same PUCCH resource set, and a PUCCH resource set contains one or more element indexes, which are determined based on the order of the PUCCH resources in the PUCCH resource set. Among them, one such index is associated with 1 or 2 PUCCH resources, and the 2 PUCCH resources have the same pucch-ResourceId or different pucch-ResourceIds. The 2 PUCCH resources are respectively associated with the SBFD symbol and the non-SBFD symbol.

[0378] The UE determines the PUCCH resource according to the PRI in the DCI and the slot type in which the PUCCH will be transmitted. For example, if the UE determines that the PUCCH will be transmitted in an SBFD slot, the UE determines a PUCCH resource from the PUCCH resources associated with the SBFD symbol in the determined PUCCH resource set based on the PRI. If the UE determines that the PUCCH will be transmitted in a non-SBFD slot, the UE determines a PUCCH resource from the PUCCH resources associated with the non-SBFD symbol in the determined PUCCH resource set based on the PRI.

[0379] Regarding the association parameter PUCCH-Resource for the PUCCH resource:

[0380] A parameter PUCCH-Resource is respectively associated with the SBFD symbol and the non-SBFD symbol.

[0381] That is to say, in a PUCCH-config, there are two independent parameters PUCCH-Resource, one associated with the SBFD symbol and the other associated with the non-SBFD symbol.

[0382] That is to say, a new parameter PUCCH-Resource (denoted as PUCCH-ResourceSBFD) is added, which is used to configure the PUCCH resource of the SBFD symbol. The original PUCCH-Resource is associated with the non-SBFD symbol and is used to configure the PUCCH resource of the non-SBFD symbol.

[0383] Based on this, the PUCCH resource set can be shared in SBFD symbols and non - SBFD symbols, that is to say, the same PUCCH resource set can be used for SBFD symbols and non - SBFD symbols. Specifically, in this PUCCH resource set, it contains one or more pucch - ResourceIds, and each pucch - ResourceId is associated with 2 PUCCH resources (associated with SBFD symbols and non - SBFD symbols respectively), and these 2 PUCCH resources come from different parameter PUCCH - Resources (for example, one PUCCH resource comes from the existing parameter PUCCH - Resource, and the other comes from the newly added parameter PUCCH - ResourceSBFD).

[0384] If mode 2 is provided for PUCCH transmission and the PUCCH transmission is configured to be repeated, then the PUCCH resources for different repetitions of this PUCCH transmission in SBFD symbols / slots and in non - SBFD symbols / slots are determined as follows:

[0385] The UE determines to perform a PUCCH transmission with repetition by receiving DCI signaling or RRC signaling, and for different repetitions of this PUCCH transmission in SBFD slots and non - SBFD slots respectively, the UE determines the PUCCH resources of this PUCCH transmission through at least one of the following:

[0386] Solution 1:

[0387] For the repetition of this PUCCH transmission in SBFD slots, the UE determines PUCCH resource 1 from the 2 PUCCH resources associated with a pucch - ResourceId, and for the repetition of this PUCCH transmission in non - SBFD slots, the UE determines PUCCH resource 2 from the 2 PUCCH resources associated with the same pucch - ResourceId.

[0388] Optionally, among them, PUCCH resource 1 and PUCCH resource 2 require at least one of the following requirements:

[0389] 1) Share one of the following multiple parameters: PUCCH - format0, PUCCH - format1, PUCCH - format2, PUCCH - format3 or PUCCH - format4.

[0390] 2) Each is configured with one of the following multiple parameters: PUCCH - format0, PUCCH - format1, PUCCH - format2, PUCCH - format3, or PUCCH - format4.

[0391] Specifically:

[0392] Both the PUCCH resource 1 and the PUCCH resource 2 are in PUCCH format 0, and the PUCCH resource 1 and the PUCCH resource 2 are respectively configured with at least one of the following parameters for SBFD symbols and non - SBFD symbols: initialCyclicShift, nrofSymbols, startingSymbolIndex;

[0393] Both the PUCCH resource 1 and the PUCCH resource 2 are in PUCCH format 1, and the PUCCH resource 1 and the PUCCH resource 2 are respectively configured with at least one of the following parameters for SBFD symbols and non - SBFD symbols: initialCyclicShift, nrofSymbols, startingSymbolIndex, timeDomainOCC;

[0394] Both the PUCCH resource 1 and the PUCCH resource 2 are in PUCCH format 2, and the PUCCH resource 1 and the PUCCH resource 2 are respectively configured with at least one of the following parameters for SBFD symbols and non - SBFD symbols: nrofPRBs, nrofSymbols, startingSymbolIndex;

[0395] Both the PUCCH resource 1 and the PUCCH resource 2 are in PUCCH format 3, and the PUCCH resource 1 and the PUCCH resource 2 are respectively configured with at least one of the following parameters for SBFD symbols and non - SBFD symbols: nrofPRBs, nrofSymbols, startingSymbolIndex;

[0396] Both the PUCCH resource 1 and the PUCCH resource 2 are in PUCCH format 4, and the PUCCH resource 1 and the PUCCH resource 2 are respectively configured with at least one of the following parameters for SBFD symbols and non - SBFD symbols: nrofSymbols, occ - Length, occ - Index, startingSymbolIndex;

[0397] 3) Share the same PUCCH-FormatConfig. If the PUCCH-FormatConfig is configured for SBFD symbols and non-SBFD symbols respectively, it is required that the parameters in the two PUCCH-FormatConfigs be the same, or the PUCCH-FormatConfig associated with the SBFD symbol be used in both the SBFD symbol and the non-SBFD symbol.

[0398] It should be noted that for different PUCCH repetitions, the requirements are the same in terms of format, maximum code rate, and modulation.

[0399] Solution 2:

[0400] For this PUCCH transmission with repetition, the UE determines one PUCCH resource from the two PUCCH resources associated with the same pucch-ResourceId to be used for this PUCCH repetition in both the SBFD symbol and the non-SBFD symbol.

[0401] Optionally, one of the PUCCH resources is determined according to at least one of the following:

[0402] 1) Determine the PUCCH resource associated with the symbol / slot type where the first repetition of this PUCCH transmission is located from the two PUCCH resources as the said one PUCCH resource.

[0403] 2) Select the PUCCH resource associated with the SBFD symbol from the two PUCCH resources as the said one PUCCH resource.

[0404] 3) If one of the two PUCCH resources is valid in both the SBFD symbol and the non-SBFD symbol, select this PUCCH resource as the said one PUCCH resource. If both resources meet the above requirements, select the PUCCH resource associated with the SBFD symbol or the non-SBFD symbol as the said one PUCCH resource.

[0405] The following provides an embodiment to solve the transmission problem of the scheduling request SR PUCCH.

[0406] In the prior art, the following two types of symbols are proposed, namely SBFD symbols and non-SBFD symbols. In addition, two transmission modes are provided, namely the following Mode 1 and Mode 2.

[0407] Mode 1: It means that a transmission is provided for execution across different time slots, and the transmission is only allowed in SBFD symbols in SBFD time slots or in non-SBFD symbols in non-SBFD time slots. For example, if a transmission is only restricted to SBFD symbols in SBFD time slots, then all transmissions of this transmission (including retransmissions and periodic transmissions) can only be in SBFD symbols in SBFD time slots. For example, if a transmission is only restricted to non-SBFD symbols in non-SBFD time slots, then all transmissions of this transmission (including retransmissions and periodic transmissions) can only be in non-SBFD symbols in non-SBFD time slots.

[0408] Mode 2: It means that a transmission is provided for execution across different time slots, and the transmission is allowed in SBFD symbols in SBFD time slots and in non-SBFD symbols in non-SBFD time slots. For example, one transmission (including periodic transmission and retransmission) of a transmission is in the SBFD symbol of slot n, and another transmission of this transmission is in the non-SBFD symbol of slot m.

[0409] For an SR configuration, it is periodic and transmitted through PUCCH resources. Therefore, after introducing SBFD symbols and non-SBFD symbols, how to determine the mode associated with this SR configuration? And in the case where this SR configuration is associated with Mode 1, how to determine whether this SR configuration is associated with SBFD symbols or non-SBFD symbols?

[0410] The base station and the UE agree to notify the UE about whether the SR configuration is associated with the above-mentioned Mode 1 or the above-mentioned Mode 2 in the following manner.

[0411] Option 1: In the signaling used to provide physical resources for this SR configuration, for example, in the RRC signaling SchedulingRequestResourceConfig, add a parameter A. Determine whether this SR configuration is associated with Mode 1 or Mode 2 based on this parameter A.

[0412] 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 the SR period composed of SBFD symbols, or can also be transmitted at the SR period composed of non-SBFD symbols. That is, if at an SR period, the resources corresponding to the SR PUCCH are composed of non-SBFD symbols or composed of SBFD symbols, the SR PUCCH at that SR period can be transmitted. And if the resources at an SR period only contain SBFD symbols, then at the SR period, the PUCCH resources used for the SR transmission are determined as: the PUCCH resources (frequency-domain resources) associated with the PUCCH resource ID associated with the SR configuration and associated with SBFD. And if the resources at an SR period only contain non-SBFD symbols, then at the SR period, the PUCCH resources used for the SR transmission are determined as: the PUCCH resources associated with the PUCCH resource ID associated with the SR configuration and associated with non-SBFD. If the resources at an SR period contain both SBFD symbols and non-SBFD symbols, then at the SR period, the SR transmission is prohibited.

[0413] Correspondingly, the base station performs the reception of the SR PUCCH according to the above parameter A setting situation and the above SR PUCCH transmission situation, which will not be elaborated here.

[0414] Furthermore, if mode 1 is determined to be the SR configuration of the UE based on the above parameter A, then the base station and the UE determine the mode associated with an SR configuration in the following manner, that is, determine in which type of symbols the SR PUCCH is transmitted.

[0415] Option 1: Add a parameter B in the signaling for providing physical resources for the SR configuration, for example, in the RRC signaling SchedulingRequestResourceConfig. Determine whether the SR configuration is associated with SBFD symbols or non-SBFD symbols based on the parameter B.

[0416] If the parameter B is set to indicate that the symbol associated with an SR configuration is an SBFD symbol, the SR PUCCH of the SR configuration is only transmitted at the SR period composed of SBFD symbols. That is, at that SR period, the resources (symbols) corresponding to the SR PUCCH are all SBFD symbols. That is, if at an SR period, the resources corresponding to the SR PUCCH contain non-SBFD symbols, the SR PUCCH at that SR period is not transmitted. Correspondingly, the base station performs the reception of the SR PUCCH according to the above parameter B setting situation and the above SR PUCCH transmission situation, which will not be elaborated here.

[0417] If the parameter B is set to identify the symbol associated with an SR configuration as a non-SBFD symbol, then 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 at an SR period, the resources corresponding to the SR PUCCH include SBFD symbols, then the SR PUCCH at that SR period is not transmitted. Correspondingly, the base station performs the reception of the SR PUCCH according to the setting of the above parameter B and the transmission situation of the above SR PUCCH, which will not be elaborated here.

[0418] The following provides an embodiment to solve the problem of the periodic transmission of CSI PUCCH.

[0419] In the prior art, the following two types of symbols are proposed, namely SBFD symbols and non-SBFD symbols. In addition, two transmission modes are provided, namely the following Mode 1 and Mode 2.

[0420] Mode 1: It means that a transmission is provided to perform transmission across different time slots, and transmission is only allowed in SBFD symbols in SBFD time slots or in non-SBFD symbols in non-SBFD time slots. For example, if a transmission is only restricted to SBFD symbols in SBFD time slots, then all transmissions (including retransmissions and periodic transmissions) of the transmission can only be in SBFD symbols in SBFD time slots. For example, if a transmission is only restricted to non-SBFD symbols in non-SBFD time slots, then all transmissions (including retransmissions and periodic transmissions) of the transmission can only be in non-SBFD symbols in non-SBFD time slots.

[0421] Mode 2: It means that a transmission is provided to perform transmission across different time slots, and transmission is allowed in SBFD symbols in SBFD time slots and in non-SBFD symbols in non-SBFD time slots. For example, one transmission (including periodic transmission and retransmission) of a transmission is in the SBFD symbols of slot n, and another transmission of the transmission is in the non-SBFD symbols of slot m.

[0422] For a CSI report configuration, the periodic CSI report in it is transmitted through PUCCH resources. Therefore, after introducing SBFD symbols and non-SBFD symbols, how to determine the mode associated with the CSI report configuration? And in the case where the CSI report configuration is associated with Mode 1, how to determine whether the CSI report configuration is associated with SBFD symbols or non-SBFD symbols?

[0423] The base station and the UE agree to notify the UE about whether the CSI report configuration is associated with the above-mentioned Mode 1 or the above-mentioned Mode 2 in the following manner.

[0424] Option 1: In a signaling CSI-ReportConfig of a CSI report configuration, or in the reportConfigType in the CSI-ReportConfig, or in the periodic in the reportConfigType in the CSI-ReportConfig, add a parameter C. Based on this parameter C, it is determined whether the periodic CSI report in this CSI report configuration is associated with Mode 1 or Mode 2.

[0425] If the parameter C is set to indicate that a CSI report configuration is associated with Mode 2, then the PUCCH (i.e., CSIPUCCH) of the periodic CSI report in this CSI report configuration can be transmitted at the period of the CSI report composed of SBFD symbols, or can also be transmitted at the period of the CSI report composed of non-SBFD symbols. That is, if at the period of a CSI report, the resource corresponding to the CSIPUCCH is composed of non-SBFD symbols or SBFD symbols, then the CSIPUCCH at the period of this CSI report can be transmitted. And if the resource at the period of a CSI report only contains SBFD symbols, then at the period of the CSI report, the PUCCH resource used by this CSI report is determined to be: the PUCCH resource (frequency-domain resource) associated with the PUCCH resource ID associated with this CSI report configuration and associated with SBFD. And if the resource at the period of a CSI report only contains non-SBFD symbols, then at the period of the CSI report, the PUCCH resource used by this CSI report is determined to be: the PUCCH resource associated with the PUCCH resource ID associated with this CSI report configuration and associated with non-SBFD. However, if the resource at the period of a CSI report contains both SBFD symbols and non-SBFD symbols, then at the period of the CSI report, the transmission of the CSIPUCCH of this CSI report is prohibited.

[0426] Correspondingly, the base station performs the reception of the PUCCH of this CSI report according to the above parameter C setting situation and the above CSIPUCCH transmission situation of the CSI report, which will not be elaborated here.

[0427] Furthermore, if Mode 1 is determined for a CSI report configuration of the UE based on the above parameter C, then the base station and the UE determine the mode associated with the periodic CSI report configuration in this CSI report in the following manner, that is, determine in which symbol type the CSIPUCCH corresponding to this periodic CSI report is transmitted.

[0428] Option 1: Add a parameter D in a signaling CSI-ReportConfig of a CSI report configuration, or in the reportConfigType in the CSI-ReportConfig, or in the periodic in the reportConfigType in the CSI-ReportConfig. Based on this parameter D, determine that the periodic CSI report in this CSI report configuration is associated with mode 1 or mode 2.

[0429] If the parameter D is set to indicate that the symbol associated with a periodic CSI report is an SBFD symbol, then the CSIPUCCH of this CSI report is only transmitted at the CSI report period composed of SBFD symbols, that is, at this CSI report period, the resources (symbols) corresponding to this CSIPUCCH are all SBFD symbols. The PUCCH resources used by this CSI report are determined to be: the PUCCH resources (frequency domain resources) associated with the PUCCH resource ID associated with this CSI report configuration and associated with SBFD. That is, if at a CSI report period, the resources corresponding to this CSIPUCCH contain non-SBFD symbols, then the CSIPUCCH at this CSI report period is not transmitted. If the resources at a CSI report period contain both SBFD symbols and non-SBFD symbols, then at the CSI report period, the transmission of the CSIPUCCH of this CSI report is prohibited.

[0430] Correspondingly, the base station performs the reception of this CSIPUCCH according to the above parameter setting situation and the above CSIPUCCH transmission situation, which will not be elaborated here.

[0431] If the parameter D is set to indicate that the symbol associated with a CSI report is a non-SBFD symbol, then the CSIPUCCH of this CSI report is only transmitted at the CSI report period composed of non-SBFD symbols, that is, at this CSI report period, the resources (symbols) corresponding to this CSIPUCCH are all non-SBFD symbols. The PUCCH resources used by this CSI report are determined to be: the PUCCH resources (frequency domain resources) associated with the PUCCH resource ID associated with this CSI report configuration and associated with non-SBFD. That is, if at a CSI report period, the resources corresponding to this CSIPUCCH contain SBFD symbols, then the CSIPUCCH at this CSI report period is not transmitted. If the resources at a CSI report period contain both SBFD symbols and non-SBFD symbols, then at the CSI report period, the transmission of the CSIPUCCH of this CSI report is prohibited.

[0432] Correspondingly, the base station performs the reception of the CSIPUCCH according to the above parameter settings and the above CSIPUCCH transmission situation, which will not be elaborated here.

[0433] The following provides an embodiment to solve the problem of periodic CSI-RS transmission.

[0434] In the prior art, the following two symbol types are proposed, namely SBFD symbols and non-SBFD symbols. In addition, two transmission modes are provided, namely the following Mode 1 and Mode 2.

[0435] Mode 1: It means that a transmission is provided for execution across different time slots, and the transmission is only allowed in SBFD symbols in SBFD time slots or in non-SBFD symbols in non-SBFD time slots. For example, if a transmission is only restricted to SBFD symbols in SBFD time slots, then all transmissions of this transmission (including repeated transmissions and periodic transmissions) can only be in SBFD symbols in SBFD time slots. For example, if a transmission is only restricted to non-SBFD symbols in non-SBFD time slots, then all transmissions of this transmission (including repeated transmissions and periodic transmissions) can only be in non-SBFD symbols in non-SBFD time slots.

[0436] Mode 2: It means that a transmission is provided for execution across different time slots, and the transmission is allowed in SBFD symbols in SBFD time slots and in non-SBFD symbols in non-SBFD time slots. For example, one transmission of a transmission (including periodic transmission and repeated transmission) is in the SBFD symbol of slot n, and another transmission of this transmission is in the non-SBFD symbol of slot m.

[0437] For a CSI-RS configuration, it is periodically transmitted. Therefore, after introducing SBFD symbols and non-SBFD symbols, how to determine the mode associated with this CSI-RS configuration? And in the case where this resource configuration is associated with Mode 1, how to determine whether this resource configuration is associated with SBFD symbols or non-SBFD symbols?

[0438] 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.

[0439] Option 1: If the UE determines that a configured CSI-ReportConfig is associated with Mode 1 and further determines that the CSI-ReportConfig is associated with SBFD symbols, then for the CSI-RS of the period associated with this CSI-ReportConfig, the following reception is performed: If the resources at this CSI-RS period consist only of SBFD symbols, then the UE receives the CSI-RS at this period. That is, if the resources at this CSI-RS period consist only of non-SBFD symbols, or contain both SBFD symbols and non-SBFD symbols, then the UE does not receive the CSI-RS at this period.

[0440] Option 2: If the UE determines that a configured CSI-ReportConfig is associated with Mode 1 and further determines that the CSI-ReportConfig is associated with non-SBFD symbols, then for the CSI-RS of the period associated with this CSI-ReportConfig, the following reception is performed: If the resources at this CSI-RS period consist only of non-SBFD symbols, then the UE receives the CSI-RS at this period. That is, if the resources at this CSI-RS period consist only of SBFD symbols, or contain both SBFD symbols and non-SBFD symbols, then the UE does not receive the CSI-RS at this period.

[0441] An embodiment of the transmission problem of HARQ-ACK PUCCH corresponding to SPS configuration is provided below.

[0442] In the prior art, the following two types of symbols are proposed, namely SBFD symbols and non-SBFD symbols. In addition, two transmission modes are provided, namely the following Mode 1 and Mode 2.

[0443] Mode 1: It means that a transmission is provided to perform transmission across different time slots, and transmission is only allowed in SBFD symbols in SBFD time slots or in non-SBFD symbols in non-SBFD time slots. For example, if a transmission is only restricted to SBFD symbols in SBFD time slots, then all transmissions of this transmission (including retransmissions and periodic transmissions) can only be in SBFD symbols in SBFD time slots. For example, if a transmission is only restricted to non-SBFD symbols in non-SBFD time slots, then all transmissions of this transmission (including retransmissions and periodic transmissions) can only be in non-SBFD symbols in non-SBFD time slots.

[0444] Mode 2: It means that a transmission is provided for execution across different time slots, and the transmission is allowed in SBFD symbols in SBFD time slots and in non-SBFD symbols in non-SBFD time slots. For example, one transmission (including periodic transmission, repeated transmission) of a transmission is in an SBFD symbol in slot n, and another transmission of the same transmission is in a non-SBFD symbol in slot m.

[0445] For the HARQ-ACK PUCCH transmission corresponding to an SPS configuration, its transmission position is determined based on the reception position of each SPS PDSCH and the position of the HARQ-ACK transmission indicated once from the active DCI of the SPS configuration. Therefore, after introducing SBFD symbols and non-SBFD symbols, how to determine the mode associated with the HARQ-ACK PUCCH transmission (especially in the case of N repetitions)? And in the case where the HARQ-ACK PUCCH transmission is associated with Mode 1, how to determine whether the HARQ-ACK PUCCH transmission is associated with an SBFD symbol or a non-SBFD symbol?

[0446] The base station and the UE agree to determine whether the above HARQ-ACK PUCCH transmission is associated with the above Mode 1 or the above Mode 2 in the following manner.

[0447] Option 1: The mode (Mode 1 or Mode 2) associated with the HARQ-ACK PUCCH transmission corresponding to an SPS configuration is determined to be the same as the mode associated with the SPS configuration. That is, if an SPS configuration is determined to be associated with Mode 1 (or Mode 2), then the HARQ-ACK PUCCH transmissions corresponding to the SPS PDSCHs at all periods of the SPS configuration are also associated with Mode 1 (or Mode 2). The UE transmits the HARQ-ACK PUCCH corresponding to the SPS PDSCH at each period of an SPS configuration based on the determined Mode 1 (or Mode 2).

[0448] Option 2: In the RRC signaling (such as SPS-Config) of an SPS configuration, a parameter E is introduced, and based on the parameter E, it is determined whether the HARQ-ACK PUCCH transmissions corresponding to the SPS PDSCHs at all periods of an SPS configuration are associated with Mode 1 or Mode 2.

[0449] Option 3: The base station and the UE agree that the HARQ-ACK PUCCH transmission corresponding to an SPS configuration is always associated with mode 2. That is, the HARQ-ACK PUCCH transmissions corresponding to the SPS PDSCHs at different periods of an SPS configuration can be transmitted either in SBFD symbols or in non-SBFD symbols. For example, the HARQ-ACK PUCCH transmission corresponding to the SPS PDSCH at the first period is transmitted in SBFD symbols, and the HARQ-ACK PUCCH transmission corresponding to the SPS PDSCH at the second period is transmitted in non-SBFD symbols.

[0450] Correspondingly, the base station performs the reception of the HARQ-ACK PUCCH according to the above settings of parameter E and the above transmission situation of the HARQ-ACK PUCCH, which will not be elaborated here.

[0451] Furthermore, if mode 1 is determined for the above HARQ-ACK PUCCH transmission (which can also have N repetitions), then the base station and the UE use the following method to determine whether the HARQ-ACK PUCCH transmission is associated only with SBFD symbols or only with non-SBFD symbols.

[0452] Option 1: For an HARQ-ACK PUCCH transmission with N (where N can be 1) repetitions corresponding to an SPS PDSCH at a period of an SPS configuration, the symbols associated with the HARQ-ACK PUCCH transmission with N repetitions are determined based on the symbol type of the symbol corresponding to the first PUCCH repetition of the N-repetition transmission. For example, if the symbol corresponding to the first PUCCH repetition consists of SBFD symbols, then all N HARQ-ACK PUCCH transmissions are transmitted in the SBFD symbols, and the PUCCH resources used are determined as: the PUCCH resources (frequency-domain resources) associated with the PUCCH resource ID associated with this SPS configuration and associated with SBFD. For example, if the symbol corresponding to the first PUCCH repetition consists of non-SBFD symbols, then all N HARQ-ACK PUCCH transmissions are transmitted in the non-SBFD symbols and the PUCCH resources used are determined as: the PUCCH resources (frequency-domain resources) associated with the PUCCH resource ID associated with this SPS configuration and associated with non-SBFD. For example, if the symbol corresponding to the first PUCCH repetition consists of both SBFD symbols and non-SBFD symbols, then the UE does not perform the N HARQ-ACK PUCCH transmissions, or postpones the N HARQ-ACK PUCCH transmissions. Note that, for each period of an SPS configuration, the symbol type associated with an HARQ-ACK PUCCH transmission corresponding to an SPS PDSCH is independently determined and the transmission is performed according to the determined symbol type.

[0453] Option 2: For an HARQ-ACK PUCCH transmission with N (N can be 1) repetitions corresponding to the SPS PDSCH at all periods of an SPS configuration, the symbols associated with the 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-repetition transmission. For example, if the symbols corresponding to the first PUCCH repetition consist of SBFD symbols, then all N HARQ-ACK PUCCH transmissions are transmitted in the SBFD symbols, and the PUCCH resources used are determined to be: the PUCCH resources (frequency-domain resources) associated with the PUCCH resource ID associated with this SPS configuration and associated with SBFD. For example, if the symbols corresponding to the first PUCCH repetition consist of non-SBFD symbols, then all N HARQ-ACK PUCCH transmissions are transmitted in the non-SBFD symbols, and the PUCCH resources used are determined to be: the PUCCH resources (frequency-domain resources) associated with the PUCCH resource ID associated with this SPS configuration and associated with non-SBFD. For example, if the symbols corresponding to the first PUCCH repetition consist of both SBFD symbols and non-SBFD symbols, then the UE does not perform the N HARQ-ACK PUCCH transmissions, or postpones the N HARQ-ACK PUCCH transmissions.

[0454] The offset for frequency hopping and the offset for determining resources are shared.

[0455] An embodiment is provided below to solve the problems related to the random access procedure.

[0456] In some embodiments, to provide more random access channel resources (or physical random access channel opportunities, abbreviated as ROs), full-duplex resources (e.g., full-duplex symbols) can be used for the transmission of the physical random access channel (PRACH). 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 RO configured within a full-duplex symbol is defined as the first type of RO, and the RO configured within a non-full-duplex symbol is defined as the second type of RO. In some embodiments, at least a portion of the configured ROs can be determined as valid ROs based on a validity judgment rule, and thus, at least a portion of different types of configured ROs can be respectively determined as different types of valid ROs. In some embodiments, when specific conditions are met, the UE can select multiple ROs from different types of valid ROs for PRACH retransmission (or PRACH transmission with preamble repetition). Specifically, the specific conditions include at least one of the following: Condition 1: The multiple selected ROs have the same frequency-domain position. Condition 2: The preambles or PRACH transmissions within the multiple selected ROs use the same transmission power. Condition 3: The preambles or PRACH transmissions within the multiple selected ROs use the same UL spatial-domain filter. Condition 4: There is no phase continuity requirement for the preamble / PRACH transmissions within the two types of ROs for the UE. Condition 5: The multiple selected ROs are associated with the same SSB (synchronization signal / physical broadcast channel block) or the same set of SSBs. Condition 6: The multiple selected ROs are continuous in the time domain, i.e., the ROs associated with the same SSB are not skipped in the time domain. Condition 7: For the multiple selected ROs, the set of preambles corresponding to the same SSB is the same. Condition 8: The multiple selected ROs are configured by a set of RACH configurations. Condition 9: Different types of ROs are configured by different RACH configurations. Condition 10: The first preamble transmission in the multiple preamble retransmissions is located within a predefined resource type, e.g., full-duplex resources. Condition 11: The physical random access channel formats (PRACH formats) carried by different types of ROs are the same.

[0457] In some embodiments, at least one of the transmission power and the UL spatial-domain filter for PRACH transmission with preamble repetition (or PRACH repetition) is determined according to the type of RO where the first preamble transmission of the preamble repetition is located. In some embodiments, at least one of the transmission power and the UL spatial-domain filter for PRACH transmission with preamble repetition (or PRACH repetition) is determined according to the configured RO type.
