In other words, the method can be implemented by software or hardware installed in the terminal device and/or network device. As shown in the figure, the method may include the following steps.

S320: The network device sends radio resource control RRC signaling.

The RRC signaling is used to indicate the number N of sub-PUCCHs.

S310: The terminal device receives radio resource control RRC signaling.

The terminal equipment acquires the number N of sub-PUCCHs through RRC signaling.

S322: The network device sends downlink control information DCI.

The DCI is used to indicate resources of N sub-PUCCHs required for current scheduling from candidate sub-PUCCH resources, where N is an integer not less than 2.

S312: The terminal device determines resources of N sub-PUCCHs required for current scheduling from candidate sub-PUCCH resources according to the DCI.

Specifically, the terminal learns the N PUCCH resources used by the HARQ-ACK that needs to be fed back for this scheduling by receiving the ARI field (HARQ-ACK resource Indicator, ARI) in the DCI information.

S314: In the case that the transmission duration of the uplink control information UCI includes the boundary of the time unit, according to the time unit, the terminal device uses N sub-PUCCHs to repeatedly transmit the UCI, wherein the transmission duration corresponding to each sub-PUCCH No more than one time unit, each sub-PUCCH may correspond to one time unit, and N is an integer not less than 2.

In one implementation, this step may include starting from the time unit corresponding to the first sub-PUCCH, that is, starting from the first time unit in which the sub-PUCCH resource carrying the UCI appears, and the next N-1 available The sub-PUCCH is transmitted in time units of .

S324: The network device receives the UCI.

Since the UCI is repeatedly transmitted, the network device can combine the sub-PUCCHs, and decode the UCI after combining to obtain the uplink control information.

In steps S322 and S312, the N sub-PUCCH resources required for current scheduling can be indicated from the candidate sub-PUCCH resources through the DCI, for example, from the candidate sub-PUCCH resources (PUCCH1-1, PUCCH1-2, PUCCH1-3, PUCCH3- 1. PUCCH3-2, PUCCH3-3) indicates that the current scheduling needs to use PUCCH3-1, PUCCH3-2, and PUCCH3-3.

In steps S324 and S314, the first time unit in which the sub-PUCCH resource carrying the UCI appears is the time unit corresponding to PUCCH3-1, and the terminal device repeatedly transmits the UCI in the next two available time units. A network device receives UCI.

Example 3

Fig. 4 shows another schematic flowchart of a method for transmitting a control channel provided by an embodiment of the present application, and the method may be executed by an electronic device, such as a terminal device and/or a network device. In other words, the method can be implemented by software or hardware installed in the terminal device and/or network device. As shown in the figure, the method may include the following steps.

S420: The network device sends radio resource control RRC signaling.

The RRC signaling is used to indicate configuration parameters of the candidate PUCCH resources, and the configuration parameters include the duration of transmission of each candidate PUCCH.

S422: The network device sends downlink control information DCI.

The DCI is used to indicate the resources of the first PUCCH required for current scheduling.

S410: The terminal device receives RRC signaling.

The terminal equipment obtains configuration parameters of candidate PUCCH resources from RRC signaling.

S412: The terminal device receives the DCI.

According to the DCI, the terminal device determines the resource of the first PUCCH required for current scheduling from the candidate PUCCH resources. The first PUCCH is one of the candidate PUCCHs. Since the RRC has configured the configuration parameters of each candidate PUCCH, the terminal device can Obtain the configuration parameters of the first PUCCH resource from the configuration parameters of the candidate PUCCH resources in the RRC signaling, where the duration of the first PUCCH transmission is included.

S414: The terminal device determines the transmission duration of the UCI carried by the first PUCCH according to the transmission duration of the first PUCCH.

S416: The terminal device determines the boundary position of the time unit, divides the first PUCCH into N sub-PUCCHs according to the boundary position of the time unit and the transmission duration of the UCI, and repeatedly transmits the UCI by the N sub-PUCCHs.

When the transmission duration of UCI carried by the first PUCCH includes the boundary of the time unit, the terminal device determines the boundary position of the time unit, and divides the first PUCCH according to the boundary position of the time unit and the transmission duration of the UCI. For or assuming that it is divided into N sub-PUCCHs, the UCI is repeatedly transmitted by the N sub-PUCCHs, where the transmission duration corresponding to each sub-PUCCH does not exceed one time unit, and N is an integer not less than 2.

S424: The network device receives the UCI.

Since the UCI is repeatedly transmitted, the network device can combine the sub-PUCCHs, and decode the UCI after combining to obtain the uplink control information.

FIG. 2b shows a schematic diagram of dividing the first PUCCH into N sub-PUCCHs according to the embodiment of the present application. As shown in the figure, in step S420, RRC signaling indicates configuration parameters of candidate PUCCH resources. For example, candidate PUCCH resources may include the configuration parameters in FIG. 2b The PUCCH3 shown may also include PUCCH1 and PUCCH2 not shown in FIG. 2 b , and the number of candidate PUCCH resources is not limited in this step. Correspondingly, in S410, the terminal device receives RRC signaling, and the terminal device obtains configuration parameters of candidate PUCCH resources (PUCCH1, PUCCH2, PUCCH3) from the RRC signaling.

In step S422, the network device sends DCI, and the DCI is used to indicate the resource of the first PUCCH required for current scheduling. The resource of the first PUCCH may be, for example, PUCCH3 shown in FIG. 2b. Correspondingly, in S412, the terminal The device receives the DCI, and according to the DCI, determines the PUCCH3 required for current scheduling from the candidate PUCCH1, PUCCH2, and PUCCH3.

In step S414, the terminal device determines the transmission duration of the UCI carried by the PUCCH3 according to the transmission duration of the PUCCH3.

In step S416, PUCCH3 is divided into 3 sub-PUCCHs (PUCCH3-1, PUCCH3-2, PUCCH3-3) according to the boundary position of the time unit and the transmission duration of UCI, by PUCCH3-1, PUCCH3-2, PUCCH3 -3 Repeat transmission of the UCI.

PUCCH3-1, PUCCH3-2, and PUCCH3-3 all transmit the UCI carried by PUCCH3, that is, PUCCH3-1, PUCCH3-2, and PUCCH3-3 carry the same UCI, and PUCCH3-1, PUCCH3-2, and PUCCH3-3 respectively transmit The duration does not exceed one time unit, and PUCCH3-1, PUCCH3-2, and PUCCH3-3 respectively correspond to one time unit. The lengths of PUCCH3-1, PUCCH3-2, and PUCCH3-3 are equal to the length of PUCCH3 in the sub-slot.

Figure 2c shows a schematic diagram of the transmission start position and the transmission end position of the example PUCCH of the present application. In one implementation, the transmission start position of the sub-PUCCH is the start position of the first PUCCH resource, or is the boundary position of the time unit corresponding to the sub-PUCCH.

In an implementation manner, the transmission end position of the sub-PUCCH is the end position of the first PUCCH resource, or the boundary position of the time unit corresponding to the sub-PUCCH.

As shown in the figure, the transmission start position of PUCCH3-1 is the start position of the first PUCCH resource, and the transmission end position is the boundary position of the corresponding time unit. The transmission start position and transmission end position of PUCCH3-2 are the boundary positions of the corresponding time unit. The transmission start position of the PUCCH3-3 is the boundary position of the corresponding time unit, and the transmission end position is the end position of the PUCCH3 resource. The length of the sub-PUCCH is equal to the length of PUCCH3 in the sub-slot.

Wherein, the time unit includes: a time slot, a sub-slot, a sub-frame or a preset duration.

Therefore, in a control channel transmission method provided in the embodiment of the present application, by determining the boundary position of the time unit, the first PUCCH is divided into N sub-PUCCHs according to the boundary position of the time unit and the transmission duration of UCI , support PUCCH transmission based on sub-slot granularity, simplify transmission control signaling steps, and further, multiple sub-PUCCHs repeatedly transmit UCI, which can effectively ensure the validity and reliability of transmission.

In addition, as shown in FIG. 2b again, as another implementation of this solution, a control channel transmission method provided by the embodiment of the present application may include: the network device indicates the configuration parameters of the candidate PUCCH through RRC signaling, and the candidate PUCCH The resource configuration parameters include resource sets of candidate PUCCHs, and the number N of (across) time units (such as sub-slots) corresponding to each candidate PUCCH. For example, the candidate PUCCH resources may include PUCCH3 shown in FIG. 2b, and may also include PUCCH1 and PUCCH2 not shown in FIG. 2b. The configuration parameters of the candidate PUCCH resources also include the number N of each candidate PUCCH cross-time unit, For example, the number of cross-time units of PUCCH1, PUCCH2, and PUCCH3.

Correspondingly, the terminal device receives RRC signaling, and the terminal device obtains configuration parameters of candidate PUCCH resources (PUCCH1, PUCCH2, PUCCH3) from the RRC signaling. The configuration parameters of candidate PUCCH resources include resource sets of candidate PUCCHs and the number N of time units spanning each candidate PUCCH.

The network device sends DCI, and the DCI is used to indicate the resource of the first PUCCH required for current scheduling. The resource of the first PUCCH may be, for example, PUCCH3 shown in FIG. 2b.

Correspondingly, the terminal device receives the DCI, and according to the DCI, determines the resources of the first PUCCH required for current scheduling. Since the RRC signaling has configured the number of time-spanning sub-PUCCH candidates, the terminal can acquire the number N of the first PUCCH time-spanning units after learning the first PUCCH used by the HARQ-ACK. For example, from the candidate PUCCH1, PUCCH2, and PUCCH3, determine the PUCCH3 required for current scheduling, and obtain the number N of PUCCH3 across time units.

In the case where the transmission duration of the UCI carried by PUCCH3 includes the boundary of a time unit, according to the time unit, the UCI is repeatedly transmitted by N sub-PUCCHs, wherein each of the sub-PUCCHs corresponds to a time unit, and N is An integer not less than 2.

As shown in Figure 2b, PUCCH3 spans 3 time units, and the UCI is repeatedly transmitted by 3 sub-PUCCHs (PUCCH3-1, PUCCH3-2, and PUCCH3-3), and PUCCH3-1, PUCCH3-2, and PUCCH3-3 all transmit UCI, that is, PUCCH3-1, PUCCH3-2, and PUCCH3-3 carry the same UCI, and the transmission duration corresponding to PUCCH3-1, PUCCH3-2, and PUCCH3-3 respectively does not exceed one time unit, and PUCCH3-1, PUCCH3- 2. PUCCH3-3 respectively correspond to a time unit. The lengths of PUCCH3-1, PUCCH3-2, and PUCCH3-3 are equal to the length of PUCCH3 in the sub-slot.
