[0043] In order to better understand the technical solutions described in any one of the embodiments of the present disclosure, first, the repeated transmission of PUCCH is described.

[0044] In one embodiment, the PUCCH is used to carry uplink control information.

[0045] In one embodiment, the PUCCH format is determined according to the uplink control information to be transmitted.

[0046] In one embodiment, the PUCCH format includes a short PUCCH format and a long PUCCH format.

[0047] In one embodiment, the short PUCCH format is a PUCCH format occupying 1 to 2 symbols.

[0048] In one embodiment, the short PUCCH format can carry 1 to 2 bits of information.

[0049] In one embodiment, the long PUCCH format is a PUCCH format occupying 4 to 14 symbols.

[0050] In one embodiment, the long PUCCH format can carry more than 2 bits of information.

[0051] In one embodiment, the uplink control information is carried by the short PUCCH format. In this way, the feedback delay of the Hybrid Automatic Repeat reQuest (HARQ) can be shortened,

[0052] In one embodiment, the uplink control information is carried by long PUCCH format. In this way, the longer duration can ensure high coverage strength.

[0053] In one embodiment, the wireless communication system does not support the transmission of PUCCH across the slot boundary or across the sub-slot boundary, nor support the repeated transmission of sub-slot-based PUCCH.

[0054] In one embodiment, for short PUCCH format, the repeated transmission of PUCCH is not supported.

[0055] For example, format 0 or format 2 does not support the repeated transmission of PUCCH.

[0056] In one embodiment, for long PUCCH format, only the repeated transmission of slot-based PUCCH is supported.

[0057] For example, format 1, format 3 or format 4, only the repeated transmission of slot-based PUCCH is supported.

[0058] In one embodiment, the number of transmissions for the repeated transmission of PUCCH is semi-statically configured.

[0059] In the related art, the repeated transmission of slot-based PUCCH cannot meet the delay requirement while ensuring the reliability requirement. In this way, the delay is large in URLLC scenarios or some beamforming scenarios.

[0060] At the same time, the repeated transmission of slot-based PUCCH does not support the repeated transmission of PUCCH of short PUCCH format. In this way, there is no corresponding repeated enhancement scheme for format 0 and format 2.

[0061] As shown in FIG. 1, a method for transmitting PUCCH is provided in the embodiment, wherein the method is applied to a terminal, and the method comprises the following steps. Figure 2a

[0062] Step 21, according to the PUCCH format supported by the terminal for the repeated transmission of PUCCH, determine the configuration parameters of the repeated transmission of PUCCH.

[0063] In some embodiments, the terminal can be, but is not limited to, a mobile phone, a wearable device, a vehicle-mounted terminal, a roadside unit (RSU), a smart home terminal, an industrial sensor device, and the like.

[0064] Here, the terminal can transmit data to the base station through the PUCCH.

[0065] ​In some embodiments, the base station can be various types of base stations, such as a base station of a third generation mobile communication (3G) network, a base station of a fourth generation mobile communication (4G) network, a base station of a fifth generation mobile communication (5G) network, or other evolved base stations.

[0066] In one embodiment, the PUCCH format includes a short PUCCH format and / or a long PUCCH format.

[0067] In one embodiment, the short PUCCH format is a PUCCH format occupying 1 to 2 symbols. For example, format 0 or format 2.

[0068] In one embodiment, the short PUCCH format can carry 1 to 2 bits of information.

[0069] In one embodiment, the long PUCCH format is a PUCCH format occupying 4 to 14 symbols. For example, format 1, format 3, or format 4.

[0070] In one embodiment, the long PUCCH format can carry more than 2 bits of information.

[0071] In one embodiment, the terminal only supports the short PUCCH format.

[0072] In one embodiment, the terminal only supports the long PUCCH format.

[0073] In one embodiment, the terminal supports both the short PUCCH format and the long PUCCH format.

[0074] In one embodiment, the PUCCH is used to carry uplink control information.

[0075] In one embodiment, the repeated transmission of the PUCCH can be the same data transmitted by different PUCCHs.

[0076] For example, the same uplink control information is transmitted by a first PUCCH, a second PUCCH, and a third PUCCH. Here, the first PUCCH, the second PUCCH, and the third PUCCH are different PUCCH resources.

[0077] In one embodiment, since the same data is transmitted by different PUCCHs, the different PUCCHs can be combined, and the combined PUCCH can be decoded to obtain the uplink control information. In this way, the reliability of transmitting the uplink control information can be improved.

[0078] In one embodiment, the PUCCH can be selected from a PUCCH resource set.

[0079] For example, the PUCCH resource set includes a first PUCCH, a second PUCCH, a third PUCCH, a fourth PUCCH, a fifth PUCCH, and a sixth PUCCH, the first PUCCH, the second PUCCH, and the third PUCCH can be selected for the repeated transmission of the PUCCH. Here, the first PUCCH, the second PUCCH, the third PUCCH, the fourth PUCCH, the fifth PUCCH, and the sixth PUCCH are different PUCCH resources.

[0080] In an embodiment, the configuration parameter includes at least one of:

[0081] The first indication parameter indicates a number of time units occupied by the single PUCCH transmission.

[0082] The second indication parameter indicates a time domain starting position occupied by the single PUCCH transmission.

[0083] The third indication parameter indicates a number of times of the repeated transmission of the PUCCH.

[0084] The fourth indication parameter indicates a repeated time unit of the repeated transmission of the PUCCH in the time domain; wherein the repeated time unit includes a slot or a sub-slot.

[0085] The fifth indication parameter indicates whether the repeated transmission of the PUCCH in the time domain supports or does not support cross-slot transmission.

[0086] In an embodiment, the single PUCCH transmission can be any one of the repeated transmission of the PUCCH.

[0087] In an embodiment, the time unit occupied by the PUCCH transmission can be a symbol.

[0088] In an embodiment, the number of time units occupied by the PUCCH in each repeated transmission is the same.

[0089] In an embodiment, the time domain starting position is a position of a PUCCH starting symbol in a slot or a sub-slot in which the PUCCH starting symbol is located.

[0090] For example, the PUCCH occupies the 3rd to 7th symbols of a slot or a sub-slot, the 3rd symbol is the time domain starting position of the PUCCH.

[0091] In an embodiment, the time domain starting position is a position of a first symbol occupied by the PUCCH transmitted in a sub-slot.

[0092] In an embodiment, the time domain starting position is a position of a first symbol occupied by the PUCCH transmitted in a slot.

[0093] In an embodiment, for the repeated transmission of the long PUCCH format PUCCH, the time domain starting position of each PUCCH repetition occupies the same symbol.

[0094] In an embodiment, for the repeated transmission of the short PUCCH format PUCCH, if the number of repeated transmissions is N (N is a positive integer greater than 1), the last N-1 PUCCH transmissions can be transmitted continuously on subsequent available resources, then the time domain starting position of the remaining (N-1) PUCCH transmissions can be determined according to the time domain starting position of the first PUCCH transmission.

[0095] In an embodiment, the number of repeated transmissions can be determined according to the transmission quality of the channel.

[0096] In an embodiment, in response to the transmission quality of the channel being less than a quality threshold, the number of repeated transmissions can be set to be greater than or equal to a quantity threshold; or, in response to the transmission quality of the channel being greater than a quality threshold, the number of repeated transmissions can be set to be less than or equal to a quantity threshold.

[0097] In this way, the number of repeated transmissions can be adaptively adjusted according to the transmission quality of the channel.

[0098] In an embodiment, the repetition time unit of the repeated transmission of the PUCCH in the time domain can be the granularity of the repetition.

[0099] In an embodiment, the repeated transmission is performed in a time slot granularity.

[0100] In another embodiment, the repeated transmission is performed in a sub-slot granularity.

[0101] In an embodiment, in response to the symbols occupied by the PUCCH transmission can exceed the boundary of the time slot, it is determined that cross-time-slot transmission is supported.

[0102] In an embodiment, in response to the symbols occupied by the PUCCH transmission can exceed the boundary of the sub-slot, it is determined that cross-time-slot transmission is supported.

[0103] In an embodiment, in response to the PUCCH format supported by the terminal for the repeated transmission of the PUCCH being a first format, it is determined that the configuration parameter of the repeated transmission of the PUCCH is a first configuration parameter; wherein the first configuration parameter at least indicates the number of repeated transmissions and the time domain starting position of each PUCCH transmission; the time domain starting position of each PUCCH transmission in a time unit is the same.

[0104] In an embodiment, in response to the PUCCH format supported by the terminal for the repeated transmission of the PUCCH being a long PUCCH format, i.e., the first format being a long PUCCH format, it is determined that the configuration parameter of the repeated transmission of the PUCCH is a first configuration parameter.

[0105] In an embodiment, the first configuration parameter indicates at least the number of repetitions and a time-domain starting position of each PUCCH transmission in a slot or a sub-slot.

[0106] In an embodiment, the time-domain starting position can be a position of a first symbol of a symbol occupied by the PUCCH transmission in the slot or the sub-slot.

[0107] In an embodiment, for the PUCCH transmission of the first format, since each slot contains the same number of symbols and each sub-slot contains the same number of symbols, when the time-domain starting position of the PUCCH transmission in one slot or one sub-slot is determined, the time-domain starting positions of the PUCCH transmission in other slots or sub-slots can be determined.

[0108] For example, for the PUCCH transmission of the first format, the repeated transmission contains 5 PUCCH transmissions, and a position of a first symbol of a symbol occupied by the first PUCCH transmission in a slot is A, then in the remaining 4 PUCCH transmissions, the starting position of the symbol occupied by each PUCCH transmission is the A position of the corresponding slot.

[0109] In this way, the time-domain starting position of the symbol occupied by each PUCCH transmission of the PUCCH repeated transmission can be obtained by one indication.

[0110] In an embodiment, in response to the PUCCH format supported by the terminal for the repeated transmission of the PUCCH being a second format, the configuration parameter of the repeated transmission of the PUCCH is determined as a second configuration parameter; wherein the second configuration parameter indicates a time-domain starting position of a first PUCCH transmission; the time-domain starting position of the first PUCCH transmission is used to determine a time-domain starting position of an (N-1)th PUCCH transmission; wherein N is a positive integer greater than 2.

[0111] In an embodiment, in response to the PUCCH format supported by the terminal for the repeated transmission of the PUCCH being a short PUCCH format, i.e., the second format being a short PUCCH format, the configuration parameter of the repeated transmission of the PUCCH is determined as a second configuration parameter.

[0112] In an embodiment, the second configuration parameter indicates at least a time-domain starting position of the first PUCCH transmission in a slot or a sub-slot.

[0113] In an embodiment, the time-domain starting position can be a position of a first symbol of a symbol occupied by the first PUCCH transmission in the slot or the sub-slot.

[0114] In one embodiment, for the PUCCH transmission of the second format, the repeated transmissions of the PUCCH are consecutive repeated transmissions.

[0115] Here, for the PUCCH transmission of the second format, since the repeated transmissions of the PUCCH are consecutive repeated transmissions, after determining the time-domain starting position of the first PUCCH transmission of the repeated transmissions, the starting position of the symbol occupied by any one of the PUCCH transmissions can be determined according to the consecutive relationship between the PUCCH transmissions of the repeated transmissions of the PUCCH. Therefore, the second configuration parameter only needs to indicate the time-domain starting position of the first PUCCH transmission, and the time-domain starting position of any one of the PUCCH transmissions can be determined through the time-domain starting position of the first PUCCH transmission.

[0116] In one embodiment, in response to the PUCCH formats supported by the terminal for the repeated transmissions of the PUCCH being the first format and the second format, the configuration parameter of the repeated transmissions of the PUCCH is determined according to the priorities of the first format and the second format.

[0117] In one embodiment, the first format is a long PUCCH format, and the second format is a short PUCCH format.

[0118] In one embodiment, the PUCCH formats supported by the terminal for the repeated transmissions of the PUCCH being the first format and the second format can be the repeated transmissions of the PUCCH in the time domain, and both the transmission of the PUCCH of the first format and the transmission of the PUCCH of the second format are supported.

[0119] In one embodiment, the first format and the second format have different priorities.

[0120] In one embodiment, in response to the priority of the first format being higher than the priority of the second format, the repeated transmissions of the PUCCH of the first format are preferentially performed based on the first configuration parameter, and then the repeated transmissions of the PUCCH of the second format are performed based on the second configuration parameter.

[0121] In one embodiment, in response to the priority of the first format being lower than the priority of the second format, the repeated transmissions of the PUCCH of the second format are preferentially performed based on the second configuration parameter, and then the repeated transmissions of the PUCCH of the first format are performed based on the first configuration parameter.

[0122] In one embodiment, the terminal receives the configuration parameters configured by the base station to the terminal through signaling. Here, the signaling can be Radio Resource Control (RRC) signaling, Media Access Control (MAC) signaling or Downlink Control Information (DCI) signaling.

[0123] In one embodiment, when the PUCCH of the long PUCCH format (for example, format 1, format 3 or format 4) needs to be repeatedly transmitted, the repeated transmission of the PUCCH based on the time slot or the sub-slot can be adopted in order to enhance the coverage or enhance the reliability of the data transmission.

[0124] In one embodiment, for the PUCCH transmission of the long PUCCH format, the transmission of the PUCCH is contained in each time slot or sub-slot, and each transmission of the PUCCH has a uniform time domain starting position, while each transmission of the PUCCH occupies the same number of symbols.

[0125] In one embodiment, if the transmission of the PUCCH occupies the symbol of the downlink transmission or the unavailable reserved resource, the transmission of the PUCCH is skipped.

[0126] For example, referring to Figure 2b , for the PUCCH transmission of the long PUCCH format, the number of repeated transmissions of the PUCCH is 4; the repeated transmission of the PUCCH is the repeated transmission of the PUCCH based on the sub-slot, that is, each sub-slot corresponds to the transmission of the PUCCH, Figure 2b , the sub-slots in the time slot include sub-slot 1, sub-slot 2, sub-slot 3 and sub-slot 4, a total of four sub-slots, and the four time slots are adjacent sub-slots; the time domain starting position is the symbol numbered 1, as shown in Figure 2b , the time domain starting positions of the symbols occupied by the PUCCH transmitted in the sub-slot 1, the sub-slot 2, the sub-slot 3 and the sub-slot 4 are all symbol 1. Among them, the number of symbols occupied by each transmission of the PUCCH is the same, Figure 2b , the number of symbols occupied by each transmission of the PUCCH is 5.

[0127] For example, referring to Figure 2c , the number of repeated transmissions of the PUCCH is 2; the repeated transmission of the PUCCH is the repeated transmission of the PUCCH based on the time slot, that is, each time slot corresponds to the transmission of the PUCCH, Figure 2cThe time slots in the time domain include slot1 and slot2, a total of two time slots; the time domain starting position is a symbol numbered 1, as shown in Figure 2c The PUCCH transmitted in slot1 and slot2 occupies a symbol whose time domain starting position is symbol 1, as shown in Figure 2c The number of symbols occupied by each PUCCH transmission is the same, In this case, the number of symbols occupied is 10. Here, the long PUCCH format is used for repeated transmission, which has good reliability and coverage enhancement.

[0128] In one embodiment, when a PUCCH of a short PUCCH format (for example, format 0 or format 2) needs to be repeatedly transmitted, in order to support multiple transmission reception points, beamforming or hybrid automatic repeat, a retransmission mode of consecutive retransmission PUCCH can be used to perform repeated transmission of consecutive PUCCH.

[0129] In one embodiment, for PUCCH transmission of a short PUCCH format, cross-slot and cross-sub-slot PUCCH transmission is supported, and when a slot boundary or a sub-slot boundary is encountered, the available symbol is not segmented.

[0130] In one embodiment, for PUCCH transmission of a short PUCCH format, if a symbol is not available (for example, the symbol is a reserved symbol), the transmission is skipped and the PUCCH is not transmitted. In this way, on the one hand, the time delay can be reduced, for example, for PDSCH transmission, ACK / NACK feedback can be obtained more quickly and timely. For example, for beamforming or multiple transmission reception point transmission, there is no interval between consecutive PUCCH transmissions, which can save beam scanning time and reduce time delay for data merging of multiple transmission reception points; on the other hand, the scattered uplink symbols can be used for repeated transmission of PUCCH at any time, which is more flexible and has higher resource utilization.

[0131] For example, please refer to Figure 2d For PUCCH transmission of a short PUCCH format, the number of repeated transmissions of PUCCH in each time slot is 3; the repeated transmission of PUCCH is consecutive PUCCH transmission, that is, the transmission of PUCCH is uninterrupted under the condition that the symbol is available; the time domain starting position is a symbol numbered 5, as shown in Figure 2d After the time domain starting position of the transmission of the first PUCCH is determined (symbol 5), the symbols occupied by the remaining 2 transmissions can be determined. The number of symbols occupied by each PUCCH transmission is the same, Figure 2d In this case, the number of symbols occupied by each PUCCH transmission is 2.

[0132] In an embodiment, for PUCCH transmission of short PUCCH format, if the symbol occupied by the PUCCH transmission is a reserved symbol, the PUCCH transmission is skipped. For example, in 2a, the symbol 7 in slot2 is a reserved symbol, the PUCCH transmission is skipped after the symbol 7. Figure 2d In an embodiment, for PUCCH transmission of short PUCCH format, if the symbol occupied by the PUCCH transmission is a downlink symbol, the PUCCH transmission is skipped. For example, in 2d, the symbols 0 to 3 in slot1 are downlink symbols, the PUCCH transmission is not performed on the symbols.

[0133] In an embodiment, for PUCCH transmission of short PUCCH format, if the symbol occupied by the PUCCH transmission is a downlink symbol, the PUCCH transmission is skipped. For example, in 2d, the symbols 0 to 3 in slot1 are downlink symbols, the PUCCH transmission is not performed on the symbols.

[0134] For example, please refer to Figure 2e For PUCCH transmission of short PUCCH format, the number of PUCCH repetition transmission in each slot is 3; the PUCCH repetition transmission is continuous PUCCH transmission, that is, the PUCCH transmission is uninterrupted between the symbols available; the time domain starting position is the symbol numbered 6, as shown in Figure 2e After the time domain starting position occupied by the first PUCCH transmission is determined (symbol 6), the symbols occupied by the remaining 2 transmissions can be determined. Among them, the number of symbols occupied by each PUCCH transmission is the same, Figure 2e In 2b, the number of symbols occupied by each PUCCH transmission is 2.

[0135] In the embodiment of the present disclosure, according to the PUCCH format supported by the terminal for the repetition transmission of the physical uplink control channel PUCCH, the configuration parameters of the PUCCH repetition transmission are determined. Here, the configuration parameters of the PUCCH repetition transmission can be determined according to the supported PUCCH format for the repetition transmission of the PUCCH. Compared with the PUCCH repetition transmission that can only be performed according to a single configuration parameter, the terminal can perform the PUCCH repetition transmission using the configuration parameters suitable for the PUCCH format, so that the requirements for reliability, delay and / or coverage strength in different scenarios can be met.

[0136] It should be noted that those skilled in the art can understand that the method provided by the embodiment of the present disclosure can be executed alone or together with some methods in some methods or related technologies in the embodiment of the present disclosure.

[0137] As shown in Figure 3 In the embodiment, a method for transmitting PUCCH is provided, wherein the method is applied to a terminal, and the method comprises the following steps:

[0138] In step 31, in response to the PUCCH format supported by the terminal for performing the repeated transmission of the PUCCH being a first format, the configuration parameter of the repeated transmission of the PUCCH is determined as the first configuration parameter; wherein the first configuration parameter indicates the number of repeated transmissions and the time domain starting position of each PUCCH transmission; the time domain starting position of each PUCCH transmission in a time unit is the same.

[0139] Alternatively,

[0140] In response to the PUCCH format supported by the terminal for performing the repeated transmission of the PUCCH being a second format, the configuration parameter of the repeated transmission of the PUCCH is determined as a second configuration parameter; wherein the second configuration parameter indicates the time domain starting position of the first PUCCH transmission; the time domain starting position of the first PUCCH transmission is used to determine the time domain starting position of the (N-1)th PUCCH transmission; wherein N is a positive integer greater than 2.

[0141] Alternatively,

[0142] In response to the PUCCH format supported by the terminal for performing the repeated transmission of the PUCCH being a first format and a second format, the configuration parameter of the repeated transmission of the PUCCH is determined according to the priority of the first format and the second format.

[0143] In one embodiment, in response to the PUCCH format supported by the terminal for performing the repeated transmission of the PUCCH being a long PUCCH format, the configuration parameter of the repeated transmission of the PUCCH is determined as a first configuration parameter.

[0144] In one embodiment, the first configuration parameter at least indicates the number of repetitions and the time domain starting position of each PUCCH transmission in a slot or a sub-slot.

[0145] In one embodiment, the time domain starting position can be the position of the first symbol of the PUCCH transmission occupying the symbol in a slot or a sub-slot.

[0146] In one embodiment, for the PUCCH transmission of the first format, since each slot contains the same number of symbols and each sub-slot contains the same number of symbols, when the time domain starting position of the PUCCH transmission in a slot or a sub-slot is determined, the time domain starting positions of the PUCCH transmissions in other slots or sub-slots can be determined.

[0147] For example, for a PUCCH transmission in the first format, a repeated transmission consists of 5 PUCCH transmissions. The first PUCCH transmission occupies the position of the first symbol of the symbol in the time slot as A. In the remaining 4 PUCCH transmissions, the starting position of the symbol occupied by each PUCCH transmission is the position A of the corresponding time slot.

[0148] Thus, the time-domain start position of the symbols occupied by each PUCCH transmission in a PUCCH retransmission can be obtained with a single instruction.

[0149] In one embodiment, in response to the terminal supporting a short PUCCH format for repeated PUCCH transmission, i.e., the first PUCCH format is the short PUCCH format, the configuration parameter for determining the repeated PUCCH transmission is the second configuration parameter.

[0150] In one embodiment, the second configuration parameter indicates at least the time-domain start position for the first PUCCH transmission within a time slot or sub-time slot.

[0151] In one embodiment, the time-domain start position can be the position of the first symbol occupied by the first PUCCH transmission within a time slot or sub-time slot.

[0152] In one embodiment, for the second format of PUCCH transmission, the repeated transmission of PUCCH is a continuous repeated transmission.

[0153] Here, for the second format PUCCH transmission, since the repeated transmission of PUCCH is a continuous repetition, after determining the time-domain start position of the first PUCCH transmission in the repeated transmission, the start position of the symbol occupied by any PUCCH transmission can be determined based on the continuity relationship between the various PUCCH transmissions in the repeated transmission. Therefore, the second configuration parameter only needs to indicate the time-domain start position of the first PUCCH transmission, and the time-domain start position of any PUCCH transmission can be determined through this first PUCCH transmission's time-domain start position.

[0154] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0155] like Figure 4 As shown, this embodiment provides a method for transmitting PUCCH, which is applied to a terminal. The method includes:

[0156] Step 41, in response to the priority of the first format being higher than the priority of the second format, the configuration parameter of the repeated transmission of the PUCCH is determined as the first configuration parameter in priority;

[0157] Or,

[0158] In response to the priority of the first format being lower than the priority of the second format, the configuration parameter of the repeated transmission of the PUCCH is determined as the second configuration parameter in priority.

[0159] In one embodiment, in response to the priority of the first format being higher than the priority of the second format, the repeated transmission of the PUCCH of the first format is performed in priority based on the first configuration parameter, and then the repeated transmission of the PUCCH of the second format is performed based on the second configuration parameter.

[0160] In one embodiment, in response to the priority of the first format being lower than the priority of the second format, the repeated transmission of the PUCCH of the second format is performed in priority based on the second configuration parameter, and then the repeated transmission of the PUCCH of the first format is performed based on the first configuration parameter.

[0161] In one embodiment, the first format is a long PUCCH format, and the second format is a short PUCCH format.

[0162] In one embodiment, the PUCCH format supported to perform the repeated transmission of the PUCCH is the first format and the second format can be the repeated transmission of the PUCCH in the time domain, that is, both the transmission of the PUCCH of the first format and the transmission of the PUCCH of the second format are supported.

[0163] In one embodiment, the first format and the second format have different priorities.

[0164] It should be noted that those skilled in the art can understand that the method provided by the embodiments of the present disclosure can be executed alone or together with some methods in some methods or related technologies in the embodiments of the present disclosure.

[0165] As Figure 5 shown, the present embodiment provides a method for transmitting PUCCH, wherein the method is applied to a terminal, and the method comprises the following steps:

[0166] Step 51, according to the configuration parameter, the PUCCH of the first format is repeatedly transmitted at intervals in the time domain;

[0167] Or,

[0168] According to the configuration parameter, the PUCCH of the second format is repeatedly transmitted continuously in the time domain.

[0169] In one embodiment, time-domain interval repetition is applicable to the repetition of long PUCCH format PUCCH.

[0170] In one embodiment, for repeated transmission of long PUCCH format PUCCH, the interval repeated transmission may be a transmission of the first format PUCCH once in each time slot in the time domain.

[0171] For example, the first PUCCH is transmitted in the first time slot, and the second PUCCH is transmitted in the second time slot.

[0172] In one embodiment, time-domain continuous repetitive transmission is applicable to the repetitive transmission of short PUCCH format PUCCH.

[0173] In one embodiment, for the repeated transmission of short PUCCH format PUCCHs, continuous repeated transmission can be achieved by transmitting the next PUCCH immediately after the previous PUCCH transmission is completed. This ensures uninterrupted transmission between adjacent PUCCHs, thereby reducing data transmission latency.

[0174] Here, for repeated transmissions of short PUCCH format PUCCHs, since the repeated transmissions are continuous, after determining the time-domain start position of the first PUCCH transmission, the start position of the symbol occupied by any PUCCH transmission can be determined based on the continuity between the various PUCCH transmissions in the repeated transmission. Therefore, the second configuration parameter only needs to indicate the time-domain start position of the first PUCCH transmission, and the time-domain start position of any subsequent PUCCH transmission can be determined from this first PUCCH transmission's time-domain start position.

[0175] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0177] Step 61: According to the configuration parameters, perform repeated transmission of PUCCH in consecutive repetitive time units in the time domain; wherein each repetitive time unit corresponds to one PUCCH transmission.

[0178] In one embodiment, the repetition time unit can be a time slot.

[0179] In one embodiment, the repetition time unit can also be a sub-slot.

[0180] In an embodiment, the repetition time unit is a time unit available.

[0181] In an embodiment, the configuration parameter indicates the repetition time unit.

[0182] In an embodiment, for the repeated transmission of the PUCCH of the long PUCCH format, the transmission of the PUCCH once per repetition time unit can be the transmission of the PUCCH once per slot.

[0183] In an embodiment, for the repeated transmission of the PUCCH of the long PUCCH format, the transmission of the PUCCH once per repetition time unit can be the transmission of the PUCCH once per sub-slot.

[0184] It should be noted that those skilled in the art can understand that the method provided by the embodiments of the present disclosure can be executed alone or together with some methods in some methods or related technologies in the embodiments of the present disclosure.
