Fig. 1 is a flowchart illustrating a transmission method of a control channel according to an embodiment of the present application, which may be performed by an electronic device, for example, a terminal device and/or a network device. In other words, the method may be performed by software or hardware installed in the terminal device and/or the network device. As shown, the method may include the following steps.

S110: and under the condition that the transmission duration of the uplink control information UCI contains the boundary of a time unit, the terminal equipment repeatedly transmits the UCI by the N sub PUCCHs according to the time unit.

Each sub-PUCCH corresponds to a time unit, each sub-PUCCH transmits the same UCI, the transmission duration corresponding to each sub-PUCCH does not exceed one time unit, and N is an integer not less than 2.

Fig. 2a shows a transmission diagram of a transmission method of a control channel according to an embodiment of the present application, and as shown in the diagram, a transmission duration of UCI includes a plurality of boundaries of 3 time units, in this case, the number of the time units is 3 according to the time units, and thus, the UCI is repeatedly transmitted by 3 sub-PUCCHs (PUCCH3-1, PUCCH3-2, PUCCH 3-3).

The PUCCH3-1, PUCCH3-2 and PUCCH3-3 carry the same UCI, the transmission duration corresponding to the PUCCH3-1, PUCCH3-2 and PUCCH3-3 respectively does not exceed one time unit, and the PUCCH3-1, PUCCH3-2 and PUCCH3-3 respectively correspond to one time unit.

S120: the network device receives the UCI.

The network device receives the UCI sent by the terminal device, and corresponding to the previous step, when the transmission duration includes a boundary of a time unit, the terminal device repeatedly transmits the UCI by N sub-PUCCHs according to the time unit, wherein each sub-PUCCH corresponds to a time unit, and N is an integer not less than 2. The transmission process of the UCI is the same as that described in the previous step, and is not described herein again.

Because the UCI is transmitted repeatedly, the network device may combine the sub-PUCCHs and decode the UCI after combination to obtain the uplink control information.

Therefore, the transmission method of the control channel provided by the embodiment of the application supports transmission of the PUCCH based on the sub-slot granularity, simplifies the step of transmitting the control signaling, and further, the UCI is repeatedly transmitted by a plurality of sub-PUCCHs, so that the effectiveness and the reliability of transmission can be effectively ensured.

In other words, the method may be performed by software or hardware installed in the terminal device and/or the network device. As shown, 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.

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

S322: the network equipment sends downlink control information DCI.

The DCI is used to indicate resources of N sub-PUCCHs required to be currently scheduled, from among the candidate sub-PUCCH resources, where N is an integer not less than 2.

S312: and the terminal equipment determines the resources of N sub-PUCCHs required to be used by current scheduling from the candidate sub-PUCCH resources according to the DCI.

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

S314: under the condition that the transmission duration of uplink control information UCI contains the boundary of a time unit, the terminal equipment repeatedly transmits the UCI by N sub-PUCCHs according to the time unit, wherein the transmission duration corresponding to each sub-PUCCH does not exceed one time unit, each sub-PUCCH can correspond to one time unit, and N is an integer not less than 2.

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

S324: the network device receives the UCI.

Referring again to fig. 2a, in steps S320 and S310, the RRC signaling may be configured with a plurality of candidate sub-PUCCH resources, for example, including PUCCH3-1, PUCCH3-2, and PUCCH3-3 shown in the figure, or may include PUCCH1-1, PUCCH1-2, PUCCH1-3 not shown in the figure, and the number of candidate sub-PUCCH resources is not specifically limited in this step.

In steps S322 and S312, the resources of N sub-PUCCHs required for current scheduling may be indicated from the candidate sub-PUCCH resources through the DCI, for example, PUCCH3-1, PUCCH3-2, PUCCH3-3 required for current scheduling is indicated from the candidate sub-PUCCH resources (PUCCH1-1, PUCCH1-2, PUCCH1-3, PUCCH3-1, PUCCH3-2, PUCCH 3-3).

In steps S324 and S314, the time unit of the first occurrence of the sub-PUCCH resource carrying the UCI is the time unit corresponding to PUCCH3-1, and the terminal device repeatedly transmits the UCI in the next 2 available time units. The network device receives the UCI.

Wherein the time cell comprises: a time slot, a sub-frame, or a preset duration, which may be a duration in milliseconds, such as 1ms, 0.5ms, etc.

Therefore, according to the transmission method of the control channel provided by the embodiment of the application, the sub-slot-based granularity of the PUCCH is supported for transmission by receiving the number N of the sub-PUCCHs configured by the network, the step of transmitting the control signaling is simplified, and further, the UCI is repeatedly transmitted by the plurality of sub-PUCCHs, so that the effectiveness and the reliability of transmission can be effectively ensured.

Example 3

Fig. 4 is another flowchart illustrating a transmission method of a control channel according to an embodiment of the present application, where the method may be performed by an electronic device, for example, a terminal device and/or a network device. In other words, the method may be performed by software or hardware installed in the terminal device and/or the network device. As shown, the method may include the following steps.

S420: the network device sends radio resource control, RRC, signaling.

The RRC signaling is used to indicate a configuration parameter of the candidate PUCCH resources, where the configuration parameter includes a duration of transmission of each candidate PUCCH.

S422: the network equipment sends downlink control information DCI.

The DCI is used for indicating the resources of the first PUCCH required to be used by current scheduling.

S410: the terminal device receives RRC signaling.

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

S412: the terminal device receives the DCI.

The terminal equipment determines the resource of a first PUCCH required to be used by current scheduling from the candidate PUCCH resources according to the DCI, wherein the first PUCCH is one of the candidate PUCCHs, and the RRC has configured the configuration parameters of each candidate PUCCH, so the terminal equipment can obtain the configuration parameters of the first PUCCH resources from the configuration parameters of the candidate PUCCH resources in RRC signaling, wherein the configuration parameters comprise the transmission duration of the first PUCCH.

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

S416: and the terminal equipment 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.

Under the condition that the transmission duration of UCI carried by a first PUCCH contains the boundary of a time unit, terminal equipment determines the boundary position of the time unit, the first PUCCH is divided or assumed to be divided into N sub-PUCCHs according to the boundary position of the time unit and the transmission duration of the UCI, the UCI is repeatedly transmitted by the N sub-PUCCHs, wherein 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.

Fig. 2b illustrates a schematic diagram of dividing the first PUCCH into N sub-PUCCHs in the embodiment of the present application, as shown in step S420, the RRC signaling indicates a configuration parameter of the candidate PUCCH resources, for example, the candidate PUCCH resources may include the PUCCH3 shown in fig. 2b, or may also include the PUCCH1, PUCCH2 and the like not shown in fig. 2b, and the number of the candidate PUCCH resources is not limited in this step. Accordingly, the terminal device receives the RRC signaling in S410, and the terminal device obtains the configuration parameters of the candidate PUCCH resources (PUCCH1, PUCCH2, PUCCH3) from the RRC signaling.

In step S422, the network device transmits DCI indicating a resource of a first PUCCH required to be used for current scheduling, which may be, for example, PUCCH3 shown in fig. 2b, and accordingly, in S412, the terminal device receives the DCI, and determines PUCCH3 required to be used for current scheduling from candidate PUCCH1, PUCCH2, PUCCH3 according to the DCI.

In step S414, the terminal device determines the transmission duration of UCI carried by PUCCH3 according to the duration of transmission of PUCCH 3.

In step S416, the 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 the UCI, and the UCI is repeatedly transmitted by PUCCH3-1, PUCCH3-2, PUCCH 3-3.

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

Fig. 2c is a schematic diagram illustrating a transmission start position and a transmission end position of a PUCCH according to an embodiment of the present application, where in an implementation manner, the transmission start position of the sub-PUCCH is a start position of the first PUCCH resource or a boundary position of a time unit corresponding to the sub-PUCCH.

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

As shown, the transmission start position of the PUCCH3-1 is the start position of the first PUCCH resource, and the transmission end position is the boundary position of its corresponding time unit. The transmission start position and the transmission end position of the PUCCH3-2 are 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 cell comprises: a time slot, a sub-frame, or a preset duration.

Therefore, according to the transmission method of the control channel provided by the embodiment of the application, the boundary position of the time unit is determined, the first PUCCH is divided into N sub-PUCCHs according to the boundary position of the time unit and the transmission duration of the UCI, the PUCCH is supported to transmit based on the granularity of sub-slots, the transmission control signaling step is simplified, further, the UCI is repeatedly transmitted by the plurality of sub-PUCCHs, and the effectiveness and the reliability of transmission can be effectively guaranteed.

In addition, referring to fig. 2b again, as another implementation manner of the present solution, a method for transmitting a control channel provided in the embodiment of the present application may include: the network device indicates the configuration parameters of the candidate PUCCHs through RRC signaling, and the configuration parameters of the candidate PUCCH resources comprise resource sets of the candidate PUCCHs and the number N of (cross) time units (such as sub-slots) corresponding to each candidate PUCCH. For example, the candidate PUCCH resource may include PUCCH3 shown in fig. 2b, and may also include PUCCH1, PUCCH2 and the like not shown in fig. 2b, and the configuration parameter of the candidate PUCCH resource further includes the number N of time units spanned by each candidate PUCCH, for example, the number of time units spanned by PUCCH1, PUCCH2 and PUCCH 3.

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

The network device transmits DCI for indicating a resource of a first PUCCH, which may be, for example, PUCCH3 shown in fig. 2b, required to be used by current scheduling.

Correspondingly, the terminal equipment receives the DCI, and determines the resource of the first PUCCH required to be used by current scheduling according to the DCI. Since the number of time-spanning units of each candidate sub-PUCCH is configured in RRC signaling, the terminal can acquire the number N of time-spanning units of the first PUCCH after acquiring the first PUCCH used by the HARQ-ACK. For example, from the candidate PUCCHs 1, 2 and PUCCH3, the PUCCH3 required to be used by the current scheduling is determined, and the number N of PUCCH3 across time units is acquired.

In the case that the transmission duration of the UCI carried by the PUCCH3 includes a boundary of a time unit, the UCI is repeatedly transmitted by N sub-PUCCHs in accordance with the time unit, wherein each sub-PUCCH corresponds to one time unit, and N is an integer not less than 2.

As shown in fig. 2b, the PUCCH3 repeatedly transmits the UCI by 3 sub-PUCCHs (PUCCH3-1, PUCCH3-2, PUCCH3-3) across 3 time units, the UCI carried by PUCCH3 is all transmitted by PUCCH3-1, PUCCH3-2, PUCCH3-3, that is, PUCCH3-1, PUCCH3-2, PUCCH3-3 carry the same UCI, the transmission durations respectively corresponding to PUCCH3-1, PUCCH3-2, PUCCH3-3 do not exceed one time unit, and PUCCH3-1, PUCCH3-2, PUCCH3-3 respectively correspond to one time unit. The length of PUCCH3-1, PUCCH3-2, PUCCH3-3 is equal to the length of PUCCH3 in the sub-slot.
