Example 1

Fig. 1 is a schematic flow chart of a method for transmitting 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 at the terminal device and/or the network device. As shown, the method may include the following steps.

S110: and the terminal equipment repeatedly transmits the UCI by N sub PUCCHs according to the time unit under the condition that the transmission duration of the UCI comprises the boundary of 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 a time unit, and N is an integer not less than 2.

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

The same UCI is carried by the PUCCH3-1, the PUCCH3-2 and the PUCCH3-3, the transmission time lengths corresponding to the PUCCH3-1, the PUCCH3-2 and the PUCCH3-3 respectively do not exceed one time unit, and the PUCCH3-1, the PUCCH3-2 and the 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 in correspondence with the previous step, the UCI is repeatedly transmitted by the terminal device according to N sub-PUCCHs according to the time unit when the transmission duration includes the boundary of the time unit, where each sub-PUCCH corresponds to a time unit, and N is an integer not less than 2. The transmission procedure of UCI is the same as that described in the previous step, and will not be described again here.

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

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

Example 2

Fig. 3 is a schematic flow chart of another method for transmitting 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 at 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.

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

S322: the network device sends downlink control information DCI.

The DCI is used for indicating the resources of N sub-PUCCHs needed to be used for current scheduling from candidate sub-PUCCH resources, wherein N is an integer not less than 2.

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

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

S314: and when the transmission duration of the uplink control information UCI comprises the boundary of a time unit, the UCI is repeatedly transmitted by N sub-PUCCHs according to the time unit, wherein the transmission duration corresponding to each sub-PUCCH does not exceed a time unit, each sub-PUCCH can correspond to a time unit, and N is an integer not less than 2.

In one implementation, this step may include transmitting the sub-PUCCH in the following N-1 available time units, starting from the time unit corresponding to the first sub-PUCCH, i.e. starting from the first time unit in which the sub-PUCCH resource carrying the UCI occurs.

S324: the network device receives UCI.

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

In steps S322 and S312, the resources of N sub-PUCCHs required for the current scheduling may be indicated from among the candidate sub-PUCCHs by DCI, for example, PUCCH3-1, PUCCH3-2, PUCCH3-3, PUCCH1-1, PUCCH1-2, PUCCH3-3 are indicated from among the candidate sub-PUCCHs resources.

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 2 available time units. The network device receives UCI.

Wherein the time unit comprises: a slot, sub-frame, or 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, through the number N of the sub-PUCCHs configured by the receiving network, the transmission of the PUCCHs based on the granularity of the sub-slot is supported, the transmission control signaling step is simplified, and furthermore, UCI is repeatedly transmitted by a plurality of sub-PUCCHs, so that the effectiveness and reliability of transmission can be effectively ensured.

Example 3

Fig. 4 is a schematic flow chart of another method for transmitting 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 at 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 for indicating configuration parameters of the candidate PUCCH resources, and the configuration parameters comprise duration time of each candidate PUCCH transmission.

S422: the network device sends downlink control information DCI.

The DCI is used to indicate resources of a first PUCCH that are currently used for scheduling.

S410: the terminal device receives the RRC signaling.

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

S412: the terminal device receives the DCI.

The terminal equipment determines the resource of the first PUCCH needed to be used for current scheduling from the candidate PUCCH resources according to DCI, wherein the first PUCCH is one of the candidate PUCCHs, and 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 because the RRC has configured the configuration parameters of each candidate PUCCH, wherein the configuration parameters comprise the duration time of the first PUCCH transmission.

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

S416: 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 UCI, and repeatedly transmits the UCI by the N sub-PUCCHs.

Under the condition that the transmission duration of the UCI carried by the first PUCCH comprises the boundary of a time unit, the terminal equipment determines the boundary position of the time unit, divides or supposedly 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 through 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 UCI.

Fig. 2b is a schematic diagram illustrating the first PUCCH being divided into N sub-PUCCHs according to the embodiment of the present application, as shown in the drawing, in step S420, the RRC signaling indicates configuration parameters of candidate PUCCH resources, for example, the candidate PUCCH resources may include PUCCH3 shown in fig. 2b, and may also include PUCCH1, PUCCH2, etc. not shown in fig. 2b, where the number of candidate PUCCH resources is not limited. Accordingly, the terminal device receives the RRC signaling in S410, and the terminal device obtains configuration parameters of candidate PUCCH resources (PUCCH 1, PUCCH2, PUCCH 3) from the RRC signaling.

In step S422, the network device transmits DCI, where the DCI is used to indicate a resource of a first PUCCH that is required for current scheduling, where the resource of the first PUCCH may be, for example, PUCCH3 shown in fig. 2b, and accordingly, in step S412, the terminal device receives the DCI, and determines, from among the candidate PUCCHs 1, 2, and 3, PUCCH3 that is required for current scheduling.

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

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

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

In one implementation, 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 in the figure, the transmission starting position of PUCCH3-1 is the starting position of the first PUCCH resource, and the transmission ending position is the boundary position of the corresponding time unit. The transmission start position and the transmission end position of the PUCCH3-2 are boundary positions of the corresponding time units. The transmission starting position of the PUCCH3-3 is the boundary position of the corresponding time unit, and the transmission ending position is the ending 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 comprises: time slots, sub-frames, or preset durations.

Therefore, according to the transmission method of the control channel, 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 transmission of the PUCCH based on granularity of sub-slots is supported, the transmission control signaling step is simplified, and furthermore, UCI is repeatedly transmitted by the sub-PUCCHs, so that the transmission effectiveness and reliability can be effectively ensured.

In addition, referring to fig. 2b again, as another implementation manner of the present solution, a transmission method of a control channel provided in the embodiment of the present application may include: the network device indicates configuration parameters of the candidate PUCCH through RRC signaling, wherein the configuration parameters of the candidate PUCCH include a resource set of the candidate PUCCH and the number N of (cross) 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 further include PUCCH1, PUCCH2, etc. not shown in fig. 2b, where the configuration parameters of the candidate PUCCH resources further include the number N of cross-time units of each candidate PUCCH, for example, the number of cross-time units of PUCCH1, PUCCH2, PUCCH 3.

Accordingly, the terminal device receives the RRC signaling, and the terminal device obtains configuration parameters of candidate PUCCH resources (PUCCH 1, PUCCH2, PUCCH 3) from the RRC signaling. The configuration parameters of the candidate PUCCH resources include a resource set of the candidate PUCCH and the number N of cross-time units per candidate PUCCH.

The network device transmits DCI indicating the resources of the first PUCCH that are currently used for scheduling, which may be, for example, PUCCH3 shown in fig. 2 b.

Accordingly, the terminal device receives the DCI, and determines the resources of the first PUCCH that are required to be used for current scheduling according to the DCI. Since the RRC signaling has configured the number of per-candidate PUCCH cross-time units, the terminal may acquire the number N of first PUCCH cross-time units after learning the first PUCCH used by HARQ-ACK. For example, PUCCH3 to be used for current scheduling is determined from among PUCCH1, PUCCH2, and PUCCH3 candidates, and the number N of PUCCH3 cross time units is obtained.

And in the case that the transmission duration of the UCI carried by the PUCCH3 comprises the boundary of a time unit, repeatedly transmitting the UCI by N sub-PUCCHs according to 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, PUCCH3 spans 3 time units, 3 sub-PUCCHs (PUCCH 3-1, PUCCH3-2, PUCCH 3-3) repeatedly transmit the UCI, PUCCH3-1, PUCCH3-2, PUCCH3-3 each transmit the UCI carried by PUCCH3, that is, PUCCH3-1, PUCCH3-2, PUCCH3-3 each carry the same UCI, the transmission duration corresponding to each of PUCCH3-1, PUCCH3-2, and PUCCH3-3 does not exceed one time unit, and each of PUCCH3-1, PUCCH3-2, and PUCCH3-3 corresponds to one time unit. The length of PUCCH3-1, PUCCH3-2, PUCCH3-3 is equal to the length of PUCCH3 in the sub-slot.
