[0019] The uplink control information transmission method provided by the embodiments of the present application will be described in detail below in combination with the drawings, specific embodiments and application scenarios.

[0020] Please refer to Figure 2 , Figure 2 is a flowchart of an uplink control information transmission method provided by the embodiments of the present application. The uplink control information transmission method includes: Step 201, the terminal determines at least one PUCCH cell corresponding to at least two UCI according to the at least two UCI.

[0021] The at least two UCI can include two UCI or more than two UCI. The terminal determines a PUCCH cell for transmitting each UCI according to each UCI (hereinafter, the PUCCH cell is also referred to as a PUCCH cell).

[0022] Step 202, the terminal transmits a first target UCI through a target PUCCH cell in the at least one PUCCH cell, the first target UCI being determined according to the at least two UCI.

[0023] After determining the at least one PUCCH cell, the terminal selects a target PUCCH cell from the at least one PUCCH cell to transmit a first target UCI. The first target UCI is determined according to the at least two UCI, for example, the first target UCI can include part of the UCI or all of the UCI in the at least two UCI.

[0024] In the embodiment, the terminal determines at least one PUCCH cell corresponding to at least two UCI according to the at least two UCI, and transmits a first target UCI through a target PUCCH cell in the at least one PUCCH cell, the first target UCI being determined according to the at least two UCI. Transmitting the first target UCI through the target PUCCH cell can improve the transmission performance of the at least two UCI.

[0025] In the above, the UCI includes at least one of the following: a hybrid automatic repeat request acknowledgement (HARQ-ACK); a scheduling request (SR); channel state information (CSI).

[0026] It can also be understood that the information type of the UCI includes at least one of the HARQ-ACK, the SR, and the CSI. For example, if UCI1 includes HARQ-ACK1 and SR1, and UCI2 includes HARQ-ACK2, then UCI1 and UCI2 both include the information type of HARQ-ACK.

[0027] Among the HARQ-ACK types, at least one of dynamically scheduled HARQ-ACK and semi-persistently scheduled (SPS) HARQ-ACK can be included. Among the dynamically scheduled HARQ-ACK, fallback DCI corresponding HARQ-ACK and non-fallback DCI corresponding HARQ-ACK can be included. The fallback DCI corresponding HARQ-ACK, for example, DCI format 1_0 scheduled PDSCH transmission or indicated SPS release corresponding HARQ-ACK feedback. The non-fallback DCI corresponding HARQ-ACK, for example, DCI format 1_1 or DCI format 1_2 scheduled PDSCH transmission or indicated SPS release corresponding HARQ-ACK feedback.

[0028] Among the SR types, at least one of SR and link recovery request (LRR) can be included.

[0029] Among the CSI types, at least one of periodic CSI, semi-persistent CSI and aperiodic CSI can be included.

[0030] Among the at least two UCIs, each UCI can include at least one of HARQ-ACK, SR and CSI. Different UCIs can include different UCI information types.

[0031] When determining the at least one PUCCH cell according to the at least two UCIs, the determination can be based on the UCI information types included in the UCIs. For example, a PUCCH cell corresponding to a certain UCI information type can be understood as a PUCCH cell where a PUCCH resource / transmission corresponding to such UCI information type is located when such UCI information type is transmitted alone.

[0032] The PUCCH cell corresponding to each UCI information type is determined as follows: HARQ-ACK type: for dynamically scheduled HARQ-ACK, when Non-fallback DCI is adopted, the PUCCH cell corresponding to the dynamically scheduled HARQ-ACK can be indicated by the dynamic scheduling DCI; when Fallback DCI is adopted, if the corresponding dynamically scheduled HARQ-ACK and the dynamically scheduled HARQ-ACK corresponding to the Non-fallback DCI are multiplexed (i.e. contained in the same HARQ-ACK codebook for transmission), the PUCCH cell indicated by one of the Non-fallback DCIs can be followed (further assuming that the HARQ-ACK codebook corresponds to one or more Non-fallback DCIs, which typically indicate the same PUCCH cell, then the above-mentioned certain Non-fallback DCI can be any of the one or more Non-fallback DCIs; alternatively, when the one or more Non-fallback DCIs indicate different PUCCH cells, the PUCCH cell indicated by the last Non-fallback DCI can be used, i.e. the HARQ-ACK codebook is transmitted on the PUCCH cell indicated by the last Non-fallback DCI), when the corresponding dynamically scheduled HARQ-ACK and the dynamically scheduled HARQ-ACK corresponding to the Non-fallback DCI are not multiplexed (i.e. all DCIs corresponding to the HARQ-ACK codebook corresponding to a certain Fallback DCI are Fallback DCIs), then the PUCCH cell corresponding to the corresponding dynamically scheduled HARQ-ACK (or the HARQ-ACK codebook in which it is located) can be determined using the SPS HARQ-ACK carrier method 2 described below.

[0033] For SPS HARQ-ACK, the determination of the corresponding PUCCH cell can use any of the following methods: SPS HARQ-ACK carrier method 1: dynamically indicated by SPS activation / reactivation DCI.

[0034] SPS HARQ-ACK carrier method 2: feedback on a certain PUCCH cell, e.g. PCell / PSCell / PUCCH SCell, which can be specified by the protocol or configured based on high-layer signaling.

[0035] When SPS HARQ-ACK is multiplexed with another SPS HARQ-ACK or dynamically scheduled HARQ-ACK, the selection / determination of the PUCCH cell corresponding to the multiplexed HARQ-ACK bit sequence can be determined according to a predefined rule.

[0036] SR Type: When a SR corresponding to a certain SR configuration (Config) is triggered, the PUCCH cell corresponding to the PUCCH transmission of a certain scheduling request resource configuration (scheduling request resource configuration) associated with the SR configuration is the PUCCH cell corresponding to the PUCCH configuration in which the scheduling request resource configuration is located (or corresponds to) (i.e. the PUCCH configuration is configured in a certain UL BWP of the PUCCH cell corresponding to the Serving cell).

[0037] CSI Type: The PUCCH cell corresponding to the CSI report is the PUCCH cell corresponding to the CSI report configuration (Report Config) of the periodic CSI or semi-persistent CSI on PUCCH (i.e. the CSI report configuration is configured in the PUCCH cell corresponding to the Serving cell).

[0038] That is, the at least one PUCCH cell corresponding to the at least two UCIs can be determined according to the following manner: In the case that the at least two UCIs include a first dynamically scheduled HARQ-ACK, the at least one PUCCH cell includes the PUCCH cell corresponding to the first dynamically scheduled HARQ-ACK, wherein the first dynamically scheduled HARQ-ACK is indicated by a first type of DCI; In the case that the at least two UCIs include a second dynamically scheduled HARQ-ACK and at least one third dynamically scheduled HARQ-ACK, the at least one PUCCH cell includes the PUCCH cell corresponding to the second dynamically scheduled HARQ-ACK, the second dynamically scheduled HARQ-ACK is indicated by a second type of DCI, the third dynamically scheduled HARQ-ACK is indicated by a first type of DCI, and the second dynamically scheduled HARQ-ACK and the at least one third dynamically scheduled HARQ-ACK are transmitted in the same HARQ-ACK codebook. In case the at least two UCIs include SPS HARQ-ACK, the at least one PUCCH cell includes the PUCCH cell dynamically indicated by the SPS activation or reactivation DCI. In case the at least two UCIs include SPS HARQ-ACK, the at least one PUCCH cell includes the PUCCH cell dynamically indicated by the SPS activation or reactivation DCI. In case the at least two UCIs include SR corresponding to one SR configuration, the at least one PUCCH cell includes the PUCCH cell corresponding to the first PUCCH transmission, wherein the first PUCCH transmission is the PUCCH transmission corresponding to the scheduling request resource configuration associated with one SR configuration. In case the at least two UCIs include periodic CSI, the at least one PUCCH cell includes the PUCCH cell configured with the first CSI reporting configuration, wherein the first CSI reporting configuration is the CSI reporting configuration corresponding to the periodic CSI carried by PUCCH. In case the at least two UCIs include semi-persistent CSI, the at least one PUCCH cell includes the PUCCH cell configured with the second CSI reporting configuration, wherein the second CSI reporting configuration is the CSI reporting configuration corresponding to the semi-persistent CSI carried by PUCCH.

[0039] In the first type of DCI, the PUCCH cell corresponding to the dynamic scheduling HARQ-ACK corresponding to the first type of DCI can be explicitly indicated by an indication field, for example, Non-fallback DCI.

[0040] In the second type of DCI, there is no indication field for explicitly indicating the PUCCH cell corresponding to the dynamic scheduling HARQ-ACK corresponding to the second type of DCI, for example, Fallback DCI.

[0041] For a certain PUCCH cell group configured for the UE, assuming that at least one serving cell (Serving cell) can be used to transmit PUCCH to feed back HARQ-ACK, it can be called PUCCH cell.

[0042] The following describes various cases of UCI transmission.

[0043] In the first case, only HARQ-ACK type is transmitted. For dynamically scheduled HARQ-ACK, at most a single PUCCH cell transmits the codebook corresponding to the dynamically scheduled HARQ-ACK at a certain time (e.g., in a certain slot or sub-slot).

[0044] For Non-fallback DCI, the above-mentioned single PUCCH cell can be directly indicated by the DCI, and when indicating or understanding K1, the K1 Set (e.g., PUCCH-Config->dl-DataToUL-ACK parameter) configured / applied by the above-mentioned single PUCCH cell is referred to.

[0045] For Fallback DCI, the determination of the above-mentioned single PUCCH cell can be: determined based on SPS HARQ-ACK carrier mode 2 when not multiplexed with HARQ-ACK corresponding to Non-fallback DCI, determined based on the PUCCH cell indicated by Non-fallback DCI when multiplexed, and the K1 Set used can still follow the pre-set provisions, such as {1, 2, 3, 4, 5, 6, 7, 8}.

[0046] In order to avoid DCI miss detection and the influence of different K1 Sets configured or applied by different PUCCH cells, it can be required that the PUCCH cells indicated in the dynamically scheduled DCI (which can be understood as Non-fallback DCI) pointing to the same time (e.g., pointing to the same slot / sub-slot) are consistent. For Fallback DCI, in order to avoid the change of the corresponding PUCCH cell (and the change of the time domain feedback position when the SCS / Numerology of the PUCCH cell corresponding is different), the network can handle / solve based on the implementation, such as for a certain HARQ-ACK codebook, first use one or more Non-fallback DCI to determine the PUCCH cell corresponding thereto, and then use Fallback DCI to indicate the HARQ-ACK further multiplexed on this HARQ-ACK codebook as needed, or, all use Fallback DCI for scheduling (at this time, the corresponding PUCCH cell does not depend on the indication of Non-fallback DCI).

[0047] For SPS HARQ-ACK, when no multiplexing occurs, the SPS HARQ-ACK can be transmitted on its corresponding PUCCH cell.

[0048] When SPS HARQ-ACK is multiplexed with another SPS HARQ-ACK or dynamically scheduled HARQ-ACK, the selection / determination of the PUCCH cell corresponding to the multiplexed HARQ-ACK bit sequence can be selected according to a predefined rule.

[0049] In the second case, the multiplexing between two or more UCI information types (including or excluding HARQ-ACK).

[0050] When PUCCH resources carrying different UCI information types are on the same PUCCH cell or different PUCCH cells and there is a time domain overlap, the multiplexing between these UCI information types can be considered. It should be noted that these PUCCH resources may be located in different PUCCH cells, and their corresponding subcarrier spacing (Subcarrier Spacing, SCS) or numerology may also be different. The judgment of time domain overlap can be based on absolute time, i.e. whether there is a time domain overlap between two PUCCH resources (or transmissions), or whether there is an overlap between the time periods corresponding to the two PUCCH resources (or transmissions). When the time periods overlap, it is determined that there is a time domain overlap. The above judgment of time domain overlap based on absolute time can be applied to the judgment of time domain overlap between PUCCH resources located in different PUCCH cells, or can be applied to the judgment of time domain overlap between PUCCH resources located in the same PUCCH cell.

[0051] When the multiplexing between the above different UCI information types involves HARQ-ACK information, whether and how to multiplex with other UCI information types can be further considered after determining the HARQ-ACK (including the HARQ-ACK codebook / bit sequence that needs to be transmitted, the corresponding PUCCH cell and PUCCH resource, etc.).

[0052] When the PUCCH resources (each corresponding to different UCI information or UCI information types) that need to be multiplexed based on time domain overlap are located (or correspond to) the same PUCCH cell, a preset rule, such as a first preset rule, is used to determine the transmission mode.

[0053] When at least one of the PUCCH resources (each corresponding to different UCI information or UCI information types) that need to be multiplexed based on time domain overlap is located (or corresponds to) a different PUCCH cell, any of the following methods can be used: At the same time, at most only a single PUCCH cell is transmitted, or multiple PUCCH cells are transmitted in parallel.

[0054] The above two modes are described below.

[0055] The first mode is the case where only a single PUCCH cell is transmitted at the same time. In this case, the terminal transmits the first target UCI through a target PUCCH cell in the at least one PUCCH cell, including: The terminal transmits the first target UCI through a target PUCCH cell in the at least two PUCCH cells, the target PUCCH cell being one of the at least two PUCCH cells, and the first target UCI being determined according to the at least two UCIs. Wherein, the PUCCH resources carrying the at least two UCIs exist time domain overlap, and the PUCCH resources carrying the at least two UCIs are located in at least two PUCCH cells.

[0056] In one case, the first target UCI is determined according to a first preset rule based on the at least two UCIs and the properties and time domain overlap of the PUCCH resources corresponding to each UCI in the at least two UCIs. The target PUCCH cell is the PUCCH cell corresponding to the PUCCH resource carrying the first target UCI.

[0057] For two or more PUCCH resources (or transmissions) carrying respective UCIs in time domain overlap, they can be located on different PUCCH cells of the same PUCCH cell group as long as the time domain overlap condition is met. After determining which PUCCH resource to use and which UCI to transmit based on the first preset rule, the finally determined PUCCH resource can be directly used for corresponding PUCCH transmission on the PUCCH cell corresponding to the PUCCH resource and within the slot / sub-slot.

[0058] The first preset rule is described below by way of example.

[0059] The following cases can be distinguished: Case 1: multiplexing HARQ-ACK and SR, or CSI and SR in PUCCH.

[0060] Specifically, for the case of a single Positive / Negative SR (not limited to PUCCH format) and Format0 HARQ-ACK (N<=2), feedback HARQ-ACK on the Format0 HARQ-ACK resource: when it is a Positive SR, adjust the CS (Cyclic Shift), otherwise (when it is a Negative SR) do not adjust the CS.

[0061] For Format0 Positive / Negative SR and Format1 HARQ-ACK (N<=2) case, Transmit HARQ-ACK normally on Format1 HARQ-ACK resource, and ignore SR.

[0062] For Format1 Positive / Negative SR and Format1 HARQ-ACK (N<=2) case, feedback HARQ-ACK on SR resource when it is Positive SR, otherwise (when it is Negative SR) feedback HARQ-ACK on HARQ-ACK resource.

[0063] For Format2 / 3 / 4 HARQ-ACK and K SR resources case, SR indication bits are appended at the end of HARQ-ACK bits, and use the dynamically scheduled HARQ-ACK PUCCH resource indicated by Last DCI.

[0064] For Format2 / 3 / 4 CSI and K SR resources case, SR indication bits are placed before CSI bits, and use the PUCCH resource reported by CSI.

[0065] Case two: multiplex HARQ-ACK, SR and CSI in PUCCH.

[0066] If there is no HARQ-ACK, or only SPS HARQ-ACK (1 bit), and transmit CSI (wideband or subband report), multiplex transmission on CSI PUCCH resource.

[0067] If there is HARQ-ACK responding to DCI (i.e. there is dynamically scheduled HARQ-ACK), multiplex transmission on the HARQ-ACK PUCCH resource indicated by Last DCI.

[0068] Case three: two kinds of physical layer priorities are configured, for each type of UCI information, and for each PUCCH / PUSCH transmission, its corresponding physical layer priority can be specified, configured or dynamically indicated, and CSI reporting is fixed to belong to the lower physical layer priority.

[0069] When there is time domain overlap between PUCCH / PUSCH transmissions of different physical layer priorities, only the PUCCH / PUSCH transmission corresponding to the higher physical layer priority is transmitted, and the PUCCH / PUSCH transmission corresponding to the lower physical layer priority is discarded. Within the same physical layer priority, the preset rule is followed, for example, the corresponding operation is performed according to the above-mentioned case one or case two.

[0070] In another case, the first target UCI includes one of the following: fusion information obtained by fusing the UCI in the at least two UCIs; part of the UCI selected from the at least two UCIs.

[0071] In the above, the fusion information is determined according to any one of the following ways: Way one: for each PUCCH cell in the at least two PUCCH cells, determine the first UCI corresponding to each PUCCH cell, and concatenate the first UCI corresponding to each PUCCH cell based on a second preset rule to obtain the fusion information.

[0072] Among them, for each PUCCH cell in the at least two PUCCH cells, in the case that the number of UCI corresponding to the PUCCH cell is equal to 1, the first UCI corresponding to the PUCCH cell is determined as the UCI corresponding to the PUCCH cell; in the case that the number of UCI corresponding to the PUCCH cell is greater than 1, the first UCI corresponding to the PUCCH cell is determined according to the UCI corresponding to the PUCCH cell according to a first preset rule.

[0073] For example, for each PUCCH cell (i.e. PUCCH cell in the at least two PUCCH cells), first determine the bit sequence of the UCI to be transmitted and the PUCCH resource based on a first preset rule, and then concatenate the bit sequence of the UCI corresponding to each PUCCH cell based on a second preset rule to obtain the fusion information. The second preset rule can be ascending or descending order of the index value corresponding to the PUCCH cell.

[0074] The index value corresponding to the PUCCH cell can be understood as the cell index (Cell index) value corresponding to the PUCCH cell, or the uplink serving cell index (UL Serving cell index) value corresponding to the PUCCH cell, or the local index value of the PUCCH cell in the set of cells allowed to transmit PUCCH, which can be numbered from 0. The index value corresponding to the PUCCH cell referred to in this paper follows the description here.

[0075] Optionally, the bit sequence of the UCI to be transmitted corresponding to each PUCCH cell can be directly obtained by concatenating the bit sequences of various UCIs to be transmitted on the PUCCH cell (the bit sequences are concatenated at the beginning and end based on a first preset rule, that is, the bit sequences of all information types of UCI present in the PUCCH cell are concatenated at the beginning and end based on the first preset rule, and if a certain information type of UCI is not present in the PUCCH cell, the UCI information type is ignored or skipped when concatenating. For example, the bit sequences corresponding to HARQ-ACK, SR, CSI part 1, and CSI part 2 are sequentially concatenated at the beginning and end, as shown in FIG. 8, and the bit sequence of the UCI to be transmitted corresponding to each PUCCH cell is directly obtained by concatenating the bit sequences of various UCIs. Figure 3a

[0076] Option 2: Determine M UCI categories that need to be transmitted according to the at least two UCIs, for a first UCI category in the M UCI categories, concatenate the second UCI corresponding to each first PUCCH cell at the beginning and end based on a second preset rule to obtain the third UCI corresponding to the first UCI category, and concatenate the third UCI corresponding to each UCI category at the beginning and end based on a third preset rule to obtain the fusion information.

[0077] UCI category includes UCI information type or UCI transmission requirement, M is an integer greater than or equal to 1, the first UCI category is any UCI category in the M UCI categories, the first PUCCH cell is any PUCCH cell in the at least two PUCCH cells that has at least one UCI corresponding to the first UCI category, the second UCI corresponding to the first PUCCH cell is determined according to the second target UCI corresponding to the first PUCCH cell, and the second target UCI includes at least one UCI corresponding to the first UCI category. The first UCI category can include one information type, or two or more information types, for example, the first UCI category can include HARQ-ACK, or HARQ-ACK and SR.

[0078] For example, if there are three types of UCI information, HARQ-ACK, SR, and CSI, for HARQ-ACK, the UCI corresponding to each PUCCH cell is screened to select the PUCCH cell where the UCI including HARQ-ACK is located, and the selected PUCCH cell is called the first PUCCH cell. For HARQ-ACK on each first PUCCH cell, concatenate at the beginning and end according to a second preset rule to obtain third UCI. The second preset rule is a cross-cell concatenation rule.

[0079] ​For the SR, the UCI corresponding to each PUCCH cell is screened, and a PUCCH cell in which the UCI including the SR is located is selected, and the selected PUCCH cell is referred to as a first PUCCH cell. For the SR on each first PUCCH cell, first concatenation is performed according to a second preset rule, and third UCI is obtained.

[0080] For the CSI, the UCI corresponding to each PUCCH cell is screened, and a PUCCH cell in which the UCI including the CSI is located is selected, and the selected PUCCH cell is referred to as a first PUCCH cell. For the CSI on each first PUCCH cell, first concatenation is performed according to a second preset rule, and third UCI is obtained.

[0081] The three third UCIs obtained in the above three types are concatenated at the beginning and the end based on a third preset rule, and the fusion information is obtained.

[0082] In the above, in a case where the number of the UCI corresponding to the first PUCCH cell is equal to 1, the second UCI corresponding to the first PUCCH cell is the UCI corresponding to the first PUCCH cell; in a case where the number of the UCI corresponding to the first PUCCH cell is greater than 1, the second UCI corresponding to the first PUCCH cell is obtained according to the UCI corresponding to the first PUCCH cell according to a fourth preset rule.

[0083] For example, the bit sequences of the UCI of the same type or the same transmission requirement in the at least two UCIs can be concatenated at the beginning and the end across the PUCCH cells based on a second preset rule, and then the concatenated output bit sequences of each different type or transmission requirement (i.e., the output of the first step concatenation operation) are concatenated at the beginning and the end based on a third preset rule to obtain the fusion information. Before being processed based on the second preset rule, if the number of the UCI corresponding to the first PUCCH cell is greater than 1, the second UCI corresponding to the first PUCCH cell is obtained according to the UCI corresponding to the first PUCCH cell according to a fourth preset rule.

[0084] For example, Figure 3b In the above, the various UCI information types are concatenated at the beginning and the end across the PUCCH cells, and then the concatenated output bit sequences corresponding to each UCI information type are concatenated at the beginning and the end. Figure 3bAs shown, first, the HARQ-ACK, SR, CSI part 1 and CSI part 2 corresponding to each PUCCH cell are respectively concatenated at the head and tail based on the ascending or descending order of the PUCCH cell index. For a certain UCI information type, when there is no corresponding UCI information to be transmitted on a certain PUCCH cell, the PUCCH cell is ignored (or skipped). Then, the concatenated output bit sequence corresponding to HARQ-ACK, SR, CSI part 1 and CSI part 2 is concatenated at the head and tail based on the third preset rule, that is, the concatenated output bit sequence of the UCI of all information types is concatenated at the head and tail based on the third preset rule. If there is no concatenated output bit sequence of a certain information type of UCI, the UCI information type is ignored or skipped during concatenation. For example, the concatenated output bit sequences corresponding to HARQ-ACK, SR, CSI part 1 and CSI part 2 are sequentially concatenated at the head and tail. Alternatively, only the concatenated output bit sequences corresponding to HARQ-ACK, SR and CSI part 1 can be concatenated to form a single bit sequence, and the CSI part 2 corresponds to another bit sequence.

[0085] For example, Figure 3c In the embodiment, first, the UCI information types corresponding to each PUCCH cell and having the same transmission requirement are concatenated at the head and tail, and then the UCI bit sequences with different transmission requirements are concatenated at the head and tail across the PUCCH cells. For example, Figure 3cAs shown, firstly, for each PUCCH cell, the corresponding HARQ-ACK, SR and CSI part 1 are concatenated at the beginning and end based on a fourth preset rule (assuming that the transmission requirements of these UCI information types are the same, they can be jointly encoded), for example, assuming that the UCI transmission requirements of HARQ-ACK, SR and CSI part 1 are the same, the bit sequences corresponding to HARQ-ACK, SR and CSI part 1 are sequentially concatenated at the beginning and end to obtain the joint bit sequence corresponding to each PUCCH cell, that is, the bit sequences of the UCI that exist in the UCI of HARQ-ACK, SR and CSI part 1 are concatenated at the beginning and end based on the fourth preset rule, if a certain information type does not exist, ignore or skip this UCI information type during concatenation. Then the joint bit sequence corresponding to each PUCCH cell is concatenated at the beginning and end based on the ascending or descending order of the PUCCH cell index to obtain a first UCI bit sequence. The CSI part 2 corresponding to each PUCCH cell can also be concatenated at the beginning and end based on the ascending or descending order of the PUCCH cell index to obtain a second UCI bit sequence. Optionally, the first UCI bit sequence and the second UCI bit sequence can be further concatenated at the beginning and end to form a single UCI bit sequence.

[0086] The first target UCI can include part of the UCI selected from the at least two UCIs. The part of the UCI includes any one of the following: The UCI in the at least two UCIs corresponding to a second PUCCH cell in the at least two PUCCH cells; The UCI in the at least two UCIs corresponding to a target type; The UCI in the at least two UCIs having a target transmission requirement.

[0087] Specifically, the UCI in the at least two UCIs corresponding to a second PUCCH cell in the at least two PUCCH cells, that is, all UCI corresponding to a single PUCCH cell to be transmitted is selected, and the UCI corresponding to other PUCCH cells to be transmitted will be discarded and not transmitted. For the UCI corresponding to the selected single PUCCH cell, the actual transmitted UCI bit sequence can be determined based on a first preset rule, or the UCI to be transmitted is concatenated at the beginning and end based on a predefined order / rule.

[0088] The selection of the single PUCCH cell can adopt any one of the following: Based on PUCCH cell index. For example, select the PUCCH cell with the largest index value, or the PUCCH cell with the smallest index value, or the PUCCH cell with a preset index value, from the at least two PUCCH cells to transmit the corresponding UCI. The preset index value can be specified by the protocol, or configured by high layer signaling, for example, when there is a time domain overlap between the UCI transmission on more than one PUCCH cell, the PUCCH cell and / or PUCCH resource selected by high layer signaling.

[0089] Based on physical layer priority, i.e., select the PUCCH cell from the at least two PUCCH cells according to the physical layer priority of each UCI. For example, select the PUCCH cell with higher physical layer priority, or the PUCCH cell with the highest physical layer priority. That is, first determine the physical layer priority or the highest physical layer priority of the UCI corresponding to each PUCCH cell, and then select the PUCCH cell with higher physical layer priority, or the PUCCH cell with the highest physical layer priority, from the multiple PUCCH cells. When there are still multiple PUCCH cells selected, the PUCCH cell can be further selected based on PUCCH cell index or based on the separately configured cell priority.

[0090] When the selected PUCCH cell corresponds to UCI with two physical layer priorities, the UCI information corresponding to the two physical layer priorities can be considered for simultaneous transmission (considering cross-physical layer priority multiplexing), or only the UCI information corresponding to the higher physical layer priority can be transmitted.

[0091] Based on the separately configured cell priority, i.e., select the PUCCH cell according to the cell priority configured for each PUCCH cell. For example, a cell priority can be configured for each PUCCH cell. Select one PUCCH cell from the at least two PUCCH cells based on the cell priority, for example, select the PUCCH cell with the highest, lowest, or specified cell priority.

[0092] The selection is based on resource availability on each PUCCH cell, i.e. the PUCCH cell is selected according to resource availability information of each PUCCH cell among the at least two PUCCH cells. For example, the selected time domain feedback position contains uplink symbols, or the corresponding PUCCH resource is available for actual transmission on the PUCCH cell. When there are still multiple PUCCH cells selected based on resource availability, the PUCCH cell can be further selected based on PUCCH cell index or based on separately configured cell priority.

[0093] Optionally, only the UCI corresponding to certain UCI information type among the UCI to be transmitted on the second PUCCH cell can be transmitted, and the rest of the UCI is discarded, for example, only HARQ-ACK and SR are transmitted, and CSI is discarded, or only HARQ-ACK, SR and CSI part 1 are transmitted, and CSI part 2 is discarded.

[0094] In the above, the target PUCCH cell can be determined based on any of the following: The selection is based on PUCCH cell index, i.e. the target PUCCH cell is selected from the at least two PUCCH cells according to the index value. For example, the PUCCH cell with the smallest, largest or specified PUCCH cell index is selected from the multiple PUCCH cells.

[0095] The selection is based on physical layer priority, i.e. the target PUCCH cell is selected from the at least two PUCCH cells according to the physical layer priority of each UCI among the at least two UCIs. For example, the PUCCH cell with higher physical layer priority, or the highest physical layer priority, can be selected, i.e. the physical layer priority or the highest physical layer priority of the UCI to be transmitted corresponding to each PUCCH cell is determined first, and then the PUCCH cell with higher physical layer priority, or the highest physical layer priority, is selected from the multiple PUCCH cells. When there are still multiple PUCCH cells selected, the PUCCH cell can be further selected based on PUCCH cell index or based on separately configured cell priority.

[0096] When the UCI to be transmitted corresponding to the selected PUCCH cell corresponds to two physical layer priorities, the UCI information corresponding to the two physical layer priorities can be considered for simultaneous transmission (considering cross-physical layer priority multiplexing), or only the UCI information corresponding to the higher physical layer priority can be transmitted.

[0097] The selection is based on the separately configured cell priority, i.e. the target PUCCH cell selects from the at least two PUCCH cells according to the cell priority configured for the PUCCH cell. For example, one cell priority can be configured for each PUCCH cell. The selection from the at least two PUCCH cells is based on the cell priority, e.g. the PUCCH cell with the highest, lowest or a specified value of the cell priority is selected.

[0098] The selection is based on the resource availability, i.e. the target PUCCH cell selects from the at least two PUCCH cells according to the resource availability information of the PUCCH cell. For example, the time domain feedback position contains uplink symbols, or the corresponding PUCCH resource is available for actual transmission of the PUCCH cell. When there are still multiple PUCCH cells selected based on the resource availability, the PUCCH cell can be further selected based on the PUCCH cell index or based on the separately configured cell priority.

[0099] The second PUCCH cell is selected from the at least two PUCCH cells, and the first target UCI includes the part or all of the UCI corresponding to the second PUCCH cell. In the case where the first target UCI includes part of the UCI, the PUCCH cell corresponding to the part of the UCI is directly selected.

[0100] The third PUCCH cell is selected from the at least two PUCCH cells, and the third PUCCH cell is the PUCCH cell that needs to transmit the codebook corresponding to the dynamically scheduled HARQ-ACK. When a PUCCH cell transmits the codebook corresponding to the dynamically scheduled HARQ-ACK, this PUCCH cell is directly selected.

[0101] The second way is the case where multiple PUCCH cells can transmit in parallel. In this case, the terminal transmits the first target UCI through the target PUCCH cell in the at least one PUCCH cell, including: In the time domain overlapping period, the terminal transmits the at least two UCIs through the at least two PUCCH cells in parallel. Among them, the PUCCH resources carrying the at least two UCIs have time domain overlap, and the PUCCH resources carrying the at least two UCIs are located in at least two PUCCH cells.

[0102] For each PUCCH cell with UCI to be transmitted, a bit sequence of the UCI to be transmitted and a PUCCH resource can be determined based on a first preset rule. When the PUCCH resources corresponding to the PUCCH cells exist in time domain overlap, parallel PUCCH transmission with time domain partial or complete overlap of the PUCCH cells is allowed.

[0103] In an embodiment of the present application, before the terminal determines at least one PUCCH cell corresponding to the at least two UCIs, the method further comprises: receiving resource configuration information of the UCI.

[0104] The resource configuration information includes at least one of the following: association information of one SR configuration and a scheduling request resource configuration configured on at least one bandwidth part (BWP) of one PUCCH cell; association information of one SR configuration and a scheduling request resource configuration configured on at least one BWP of N PUCCH cells, where N is an integer greater than 1; a CSI reporting configuration configured on a PUCCH cell for transmitting CSI.

[0105] The SR resource configuration and the CSI resource configuration are described below respectively.

[0106] For the SR resource configuration, one SR configuration can be associated with one to multiple scheduling request resource configurations configured on one to multiple BWPs of one to multiple PUCCH cells.

[0107] PUCCH carrier switching includes a dynamic mode (i.e., Alt. 1) and a semi-static mode (i.e., Alt. 2C).

[0108] When the dynamic PUCCH carrier switching mode is used, one SR configuration can be associated with a scheduling request resource configuration configured on one to multiple BWPs of a single PUCCH cell, and the scheduling request resource configuration can be a single scheduling request resource configuration.

[0109] When PUCCH carrier switching semi-static manner is adopted, a single SR configuration can be associated to one or more scheduling request resource configurations configured on one or more BWPs of multiple PUCCH cells, for example, associated to N PUCCH cells, where N is the number of PUCCH cells included in a set of PUCCH cells in an active or available state at different time periods based on a time domain pattern, and the N PUCCH cells are included in the set. The time domain pattern can be configured uniformly for M PUCCH cells in a current PUCCH cell group, or configured separately for each PUCCH cell.

[0110] For the case of PUCCH carrier switching Alt. 2C, when SR transmission corresponding to the SR configuration is triggered (for example, when one or more logical channels associated with the SR configuration trigger a regular BSR, and no suitable UL-SCH resource is available), the PUCCH cell corresponding to the PUCCH transmission carrying the SR (hereinafter referred to as SR PUCCH) can be determined based on the time domain pattern (optionally, it can also be not subject to the time domain pattern).

[0111] Specifically, when a scheduling request resource configuration associated with the SR configuration is configured on the active BWP of a PUCCH cell in an active or available state based on the time domain pattern, the periodicity and offset based on the scheduling request resource configuration, and the PUCCH resource transmission SR PUCCH. During the continuous multiple transmissions of SR PUCCH, if the active / available PUCCH cell changes based on the time domain pattern, the SR PUCCH transmission is switched / transferred from at least one PUCCH cell (i.e. the PUCCH cell in an active / available state before the change) to another at least one PUCCH cell (i.e. the PUCCH cell in an active / available state after the change). When no scheduling request resource configuration associated with the SR configuration is configured on the active BWP of any PUCCH cell after the change, the SR transmission is interrupted or suspended.

[0112] For each of the scheduling request resource configurations associated with the same SR configuration, the configuration of the periodicity and the offset can be in any of the following ways (both applicable when PUCCH carrier switching Alt. 1 or Alt. 2C is used; for operations only applicable in certain cases, the corresponding descriptions will be given below): Configuration way 1: The periodicity and the offset are uniformly configured, and are based on a reference SCS or a reference numerology. That is, in the case where the same SR configuration included in the resource configuration information is associated with at least two scheduling request resource configurations: the periodicity and the offset of each of the at least two scheduling request resource configurations are uniformly configured based on a reference subcarrier spacing or a reference numerology.

[0113] Here, the main purpose is to ensure the strict periodicity of SR transmission, and when PUCCH cell switching and / or BWP switching occurs during multiple consecutive SR PUCCH transmission processes, the time interval between adjacent SR PUCCH transmissions can be equal or substantially equal (the time intervals of the SR PUCCH resources configured on each PUCCH cell and / or BWP are equal).

[0114] Optionally, in the case where a single time unit determined based on the reference subcarrier spacing or the reference numerology corresponds to multiple time units on the fourth PUCCH cell, a target time unit is selected from the multiple time units based on a fifth preset rule for determining the SR PUCCH resource corresponding to the second scheduling request resource configuration. The fourth PUCCH cell is the PUCCH cell corresponding to the second scheduling request resource configuration, and the second scheduling request resource configuration is any of the at least two scheduling request resource configurations. A time unit can include a slot or a sub-slot.

[0115] For example, when a reference slot (i.e., a single slot determined based on a reference SCS or numerology) corresponds to multiple uplink slots / sub-slots on a certain valid PUCCH cell (on which SR PUCCH resources are configured), in the case where it is necessary to transmit SR PUCCH on the PUCCH cell: For any Configuration, It is necessary to determine which of the multiple uplink slots / sub-slots to select for transmitting SR PUCCH, and any of the following ways can be used: Slot / Sub-slot satisfying a predefined condition, when there are multiple Slot / Sub-slot satisfying the predefined condition, the earliest Slot / Sub-slot among the multiple Slot / Sub-slot can be further selected. For example, the first / last / specified index Slot / Sub-slot among the multiple uplink Slot / Sub-slot is selected. That is, the target time unit includes one of the following: a time unit in the multiple time units that can accommodate the SR PUCCH resource; the earliest time unit in the multiple time units that can accommodate the SR PUCCH resource; the first time unit in the multiple time units; the last time unit in the multiple time units; a time unit in the multiple time units corresponding to the first specified index.

[0116] The predefined condition can be that the SR PUCCH resource to be transmitted can be accommodated. Here, the PUCCH resource is determined to ensure that the corresponding PUCCH transmission can be actually performed, for example, the PUCCH resource does not overlap / conflict with Semi-static DL; symbol / SSB / CORESET#0 symbol.

[0117] Optionally, when sym2 or sym6or7, any of the following can be used: Configuration mode 1-1: This type of periodicity configuration is not allowed to avoid corresponding processing; Configuration mode 1-2: The starting time or absolute starting time of the SR PUCCH resource on each PUCCH cell associated with the same SR configuration is required to be aligned, and the interval between the starting times of adjacent PUCCH resources or transmission occasions is The corresponding absolute duration (which can be determined based on the reference SCS or parameter set) to ensure the periodicity between the time-domain adjacent SR PUCCH resources when PUCCH cell switching and / or BWP switching occurs; Configuration mode 1-3: The operation of selecting a single uplink Slot / Sub-slot from multiple uplink Slot / Sub-slot as described above applies to the "for any Configuration" and for this selected single uplink Slot / Sub-slot, .

[0118] Configuration Mode 2: Each scheduling request resource configuration is configured with corresponding periodicity and offset, and is based on the SCS or numerology corresponding to the PUCCH cell and UL BWP where it is located. That is, in the case where the same SR configuration in the resource configuration information is associated with at least two scheduling request resource configurations, a first scheduling request resource configuration in the at least two scheduling request resource configurations is configured based on target information, where the first scheduling request resource configuration is any scheduling request resource configuration in the at least two scheduling request resource configurations, and the target information is the subcarrier spacing or numerology corresponding to the PUCCH cell and uplink UL BWP where the first scheduling request resource configuration is located.

[0119] For CSI resource configuration: The CSI-ReportConfig corresponding to periodic CSI or semi-persistent CSI reporting is configured on the PUCCH cell that carries the periodic CSI or semi-persistent CSI. Each PUCCH cell can be independently configured with the CSI-ReportConfig corresponding to periodic CSI or semi-persistent CSI reporting.

[0120] For periodic CSI on PUCCH, it is considered to be in an active state when the active (Active) BWP of the PUCCH cell where it is located (or corresponding to) is the uplink BWP configured for this periodic CSI reporting, otherwise it is considered to be in a suspended state. Alternatively, when PUCCH carrier switching Alt. 2C is used, for periodic CSI on PUCCH, it is considered to be in an active state when the PUCCH cell where it is located (or corresponding to) is in an active or available state based on the time domain pattern, and the Active BWP of this PUCCH cell is the uplink BWP configured for this periodic CSI reporting, otherwise it is considered to be in a suspended state.

[0121] For semi-persistent CSI on PUCCH, after being activated based on MAC CE, if it is not deactivated by MAC CE, it is considered to be in an active state when the Active BWP of the PUCCH cell where it is located (or corresponding to) is the uplink BWP configured for this semi-persistent CSI reporting, otherwise it is considered to be in a suspended state. Alternatively, when PUCCH carrier switching Alt. 2C is used, for semi-persistent CSI on PUCCH, after being activated based on MAC CE, if it is not deactivated by MAC CE, it is considered to be in an active state when the PUCCH cell where it is located (or corresponding to) is in an active / available state based on the time domain pattern, and the Active BWP of this PUCCH cell is the uplink BWP configured for this semi-persistent CSI reporting, otherwise it is considered to be in a suspended state.

[0122] When PUCCH carrier switching Alt. 2C is adopted, generally, it can be assumed that only a single PUCCH cell is actually valid or in an active state based on a time domain mode at a certain moment, and then UCI multiplexing or prioritization operation can be performed on the PUCCH cell according to certain protocol rules.

[0123] For PUCCH carrier switching, when dynamic indication mode Alt. 1 is adopted, the HARQ-ACK feedback delay can be shortened for multiplexing and transmission between different UCI information types, and the transmission performance of other UCI information types can be further guaranteed. Other UCI information types can be switched to the PUCCH cell based on the PUCCH cell switching of the DG HARQ-ACK and the corresponding multiplexing rules, and the PUCCH cell is switched synchronously to ensure the transmission thereof.
