In order to facilitate the understanding of the technical solutions of the embodiments of the present application, the technical solutions related to the embodiments of the present application are described below.

5G NR Rel-15 stipulates that only one PUCCH carrying ACK/NACK information can be transmitted in a time slot. This kind of PUCCH is called slot-based PUCCH. A slot-based PUCCH can occupy all or part of the time domain resources in a slot. If the ACK/NACK information of multiple downlink channels is transmitted through one time slot, the ACK/NACK information of the multiple downlink channels is multiplexed and transmitted through a slot-based PUCCH.

For the Ultra-reliable Low Latency (URLLC) service in Rel-16, in order to meet the short-latency requirements, it further supports sub-slot-based ACK/NACK feedback. At this time, sub-slots are used as resource units to determine the time interval between the Physical Downlink Shared Channel (PDSCH) and the PUCCH that transmits the corresponding ACK/NACK information. This kind of PUCCH is called sub-slot-based. Time slot PUCCH (sub-slot-based PUCCH). A sub-slot-based PUCCH can only occupy time domain resources in one sub-slot for transmission, that is, sub-slot-based PUCCH cannot be transmitted across sub-slots. The time domain resources of the sub-slots can include 2 symbols or 7 symbols, and multiple sub-slot-based PUCCHs carrying ACK/NACK information can be transmitted in one slot.

In addition, NR Rel-16 can construct two HARQ-ACK feedback codebooks (codebooks) at the same time for terminal devices that support different types of services. The following description will abbreviate the HARQ-ACK feedback codebooks as feedback codebooks. The two feedback codebooks respectively correspond to different priorities (priority number 0 is low priority, priority number 1 is high priority). The priority information of the PUCCH carrying the feedback codebook is the same as the priority information corresponding to the feedback codebook. The two feedback codebooks can be configured to transmit via slot-based PUCCH or sub-slot-based PUCCH respectively, namely:

●One feedback codebook is transmitted through slot-based PUCCH, and the other feedback codebook is transmitted through sub-slot-based PUCCH; or,

● Both feedback codebooks are transmitted via slot-based PUCCH; or,

● Both feedback codebooks are transmitted via sub-slot-based PUCCH.

It should be noted that the feedback codebook transmitted via slot-based PUCCH may also be called a "slot-based codebook". The feedback codebook transmitted through the sub-slot-based PUCCH can also be called "sub-slot-based codebook".

When the terminal device supports two feedback codebooks, the two feedback codebooks respectively correspond to different priorities, and the priority information of the PUCCH carrying the feedback codebook is the same as the priority information corresponding to the feedback codebook. The priority information can also be applied to other uplink channels, that is, each uplink channel of the terminal device has a corresponding priority information. A terminal device needs to send multiple uplink channels in a time slot. If the time domains of multiple uplink channels of the same priority overlap, the terminal device determines a multiplexed channel for the priority level, which is used to transmit the priority channel. Information carried in all channels. Since the two feedback codebooks respectively correspond to two priorities, two multiplexed channels to be transmitted can be obtained, and the two multiplexed channels to be transmitted respectively correspond to different priorities. If the time domains of the two multiplexed channels to be transmitted overlap, only the multiplexed channel with the higher priority is transmitted. If the time domains of the two multiplexed channels to be transmitted do not overlap, the two multiplexed channels to be transmitted are transmitted separately.

3GPP limits that only one slot-based PUCCH carrying ACK/NACK information can be transmitted in a time slot. However, according to the above description, when the terminal device supports two feedback codebooks carrying ACK/NACK information, and at least one feedback codebook is transmitted through slot-based PUCCH, multiple ACK/NACK-bearing feedback codes will be transmitted in one time slot. The PUCCH of NACK information, and multiple PUCCHs include at least one slot-based PUCCH, this situation is contrary to the constraint of slot-based PUCCH, thereby increasing the processing complexity of the terminal device. To this end, the following technical solutions of the embodiments of the present application are proposed.

FIG. 2 is a schematic flowchart of an uplink control information transmission method provided by an embodiment of the application. As shown in FIG. 2, the uplink control information transmission method includes the following steps:

Step 201: The terminal device receives first configuration information, where the first configuration information is used to instruct the terminal device to generate at least two feedback codebooks, and the at least two feedback codebooks include a first feedback codebook and a second feedback codebook. Codebook.

In the embodiment of the present application, the terminal device receives the first configuration information sent by the network device, where the network device may be a base station, such as a gNB.

In the embodiment of the present application, the first configuration information is used to instruct the terminal device to generate at least two feedback codebooks, and the at least two feedback codebooks include a first feedback codebook and a second feedback codebook.

It should be noted that the embodiment of the present application takes the at least two feedback codebooks including two feedback codebooks as an example for description, but it is not limited to this, and the at least two feedback codebooks may also include a larger number of feedbacks. Codebooks, for example, the at least two feedback codebooks include a first feedback codebook, a second feedback codebook, and a third feedback codebook.

Step 202: In the case that the terminal device determines to construct the first feedback codebook and/or the terminal device determines to transmit the first PUCCH carrying the first feedback codebook, the terminal device determines not to construct the The second feedback codebook and/or the terminal determines not to transmit the second PUCCH carrying the second feedback codebook; wherein, the first PUCCH and the second PUCCH are both located in the first time slot.

In the embodiment of the present application, the PUCCH that carries the first feedback codebook is the first PUCCH, and the PUCCH that carries the second feedback codebook is the second PUCCH. Wherein, the first PUCCH and the second PUCCH are both located in the first time slot.

In the embodiment of the present application, if the terminal device determines to construct the first feedback codebook and/or the terminal device determines to transmit the first PUCCH carrying the first feedback codebook, the terminal device It is determined not to construct the second feedback codebook and/or the terminal determines not to transmit the second PUCCH carrying the second feedback codebook. The technical solutions of the embodiments of the present application will be described in detail below in conjunction with the specific implementation of the first PUCCH and the second PUCCH.

●Scenario 1: The first PUCCH is a slot-based PUCCH (slot-based PUCCH); the second PUCCH is a slot-based PUCCH (slot-based PUCCH) or a sub-slot based PUCCH (sub-slot -based PUCCH).

In the embodiment of the present application, the priority number of the first feedback codebook is the first number, and the first number is used to indicate that the priority of the first feedback codebook is the first priority (such as high priority). ). Further, optionally, the first number is 1, for example.

In this case, the terminal device determines to construct the first feedback codebook and/or the terminal device determines to transmit the first PUCCH carrying the first feedback codebook, and the terminal device determines not to construct Feedback codebooks other than the first feedback codebook among the at least two feedback codebooks and/or the terminal determines not to transmit a second PUCCH, and the second PUCCH is used to carry the at least two feedbacks A feedback codebook other than the first feedback codebook in the codebook.

In an example, taking the at least two feedback codebooks including two feedback codebooks as an example, the feedback codebook of the at least two feedback codebooks other than the first feedback codebook is the The second feedback codebook.

It should be noted that the description of "no construction" in the implementation of this application can be equivalently replaced with "skip construction", or "drop construction", or "stop construction", or "Is not expected to build".

● Case 2: The first PUCCH is a sub-slot-based PUCCH (slot-based PUCCH); the second PUCCH is a slot-based PUCCH (slot-based PUCCH).

In the embodiment of the present application, the priority number of the first feedback codebook is the first number, and the first number is used to indicate that the priority of the first feedback codebook is the first priority (such as high priority). ). Further, optionally, the first number is 1, for example. In addition, the priority number of the second feedback codebook is a second number, and the second number is used to indicate that the priority of the second feedback codebook is a second priority (such as a low priority), and the The second priority is lower than the first priority. Further, optionally, the first number is 1, for example. The second number is 0, for example.

In this case, the terminal device determines to construct the first feedback codebook and/or the terminal device determines to transmit the first PUCCH carrying the first feedback codebook, and the terminal device determines not to construct The second feedback codebook and/or the terminal determines not to transmit a second PUCCH, and the second PUCCH is used to carry the second feedback codebook of the at least two feedback codebooks.

It should be noted that the description of "no construction" in the implementation of this application can be equivalently replaced with "skip construction", or "drop construction", or "stop construction", or "Is not expected to build".

In the above solution, optionally, the slot-based PUCCH has one of the following features:

The time domain unit of the time slot-based PUCCH is a time slot;

One time slot includes at most one time-slot-based PUCCH, and the time-slot-based PUCCH is used to carry a feedback codebook;

The maximum time domain length of the time slot-based PUCCH is one time slot;

The time domain length of the time slot-based PUCCH does not exceed one time slot.

In the above solution, optionally, the sub-slot-based PUCCH has one of the following features:

The time domain unit of the sub-slot-based PUCCH is a sub-slot or N time-domain symbols;

A time slot includes multiple sub-slot-based PUCCHs, and the sub-slot-based PUCCH is used to carry a feedback codebook;

The maximum time domain length of the sub-slot-based PUCCH is one sub-slot or N time-domain symbols;

The time domain length of the sub-slot-based PUCCH does not exceed one sub-slot or N time-domain symbols;

Wherein, the N is a positive integer, and the value of N is less than the number of time domain symbols included in one time slot.

In the technical solution of the embodiment of the present application, even if the time domains of the first PUCCH and the second PUCCH do not overlap, since the first PUCCH and the second PUCCH belong to the same time slot, the terminal device is also It will choose not to transmit one of the low-priority channels to ensure that there can be at most one high-priority slot-based PUCCH carrying the feedback codebook in a time slot, thereby simplifying the processing complexity of the end device.

In an optional manner, when the terminal device determines not to construct the second feedback codebook and/or the terminal determines not to transmit the second PUCCH carrying the second feedback codebook, the terminal device The multiplexed channel is determined according to at least one uplink channel, where any one of the at least one uplink channel and all channels included in the second PUCCH overlaps with at least one other channel among all the channels, and the at least one The priority of the uplink channel is the same as the priority of the second PUCCH.

For example: For the first time slot, the terminal device needs to transmit uplink channel 1, uplink channel 2 and uplink channel 3. These three channels have the same priority, and one of these three channels overlaps with the other one or two channels. Then, if the terminal device determines not to transmit the uplink channel 2 (the channel is the PUCCH carrying the feedback codebook), the multiplexing channel is determined according to the uplink channel 1 and the uplink channel 3.

It should be noted that if the terminal device determines not to construct the second feedback codebook and/or does not transmit the second PUCCH carrying the second feedback codebook, the second PUCCH does not participate in determining the same priority Processing of multiplexed channels of sub-channels. Here, the terminal device determining not to construct the second feedback codebook can also be equivalently understood as the terminal device not transmitting the second PUCCH. Since the terminal device first determines not to transmit the second PUCCH, and then determines the multiplexing channel with the same priority, this can avoid channel multiplexing processing on the second PUCCH, that is, because it is determined not to transmit a certain PUCCH carrying the feedback codebook Before determining the action of multiplexing channels, unnecessary channel multiplexing processing actions can be avoided.

In an optional manner, after receiving the first PDSCH or the downlink control signaling used to schedule the first PDSCH, the terminal device determines to construct the first feedback codebook and/or determines to transmit the first feedback The first PUCCH of the codebook; wherein the feedback information corresponding to the first PDSCH is carried in the first feedback codebook.

The following describes the technical solutions of the embodiments of the present application with specific application examples.

Application example one

The terminal device is configured to generate two feedback codebooks, feedback codebook 0 and feedback codebook 1. The two feedback codebooks have different priorities, corresponding to priority numbers 0 and 1, respectively, where 1 represents high priority, and 0 Represents low priority. The feedback codebook 0 is transmitted through slot-based PUCCH 0, and the feedback codebook 1 is transmitted through slot-based PUCCH 2.

As shown in Figure 3, the terminal device first receives the PDSCH 0 and determines that its corresponding feedback information (ie ACK/NACK information) is transmitted in the first time slot, and the priority of the corresponding feedback codebook 0 is low priority. That is, the priority of the corresponding slot-based PUCCH 0 is also low priority. Then, the terminal device receives the PDSCH 1 again, and determines that the corresponding feedback information is also transmitted in the first time slot. The priority of the corresponding feedback codebook 1 is high priority, that is, the priority of the corresponding slot-based PUCCH 1 The level is also high priority. Although slot-based PUCCH 0 and slot-based PUCCH 1 are both slot-based PUCCH, the actual time domain resources occupied by the two do not overlap. The terminal device still does not transmit slot-based PUCCH 0.

The terminal device can stop generating the feedback codebook after determining to send slot-based PUCCH 1 (the terminal device can know to send slot-based PUCCH 1 after receiving the PDSCH 1 or receiving the downlink control signaling for scheduling PDSCH 1). Or stop preparing slot-based PUCCH 0, so that slot-based PUCCH 0 is not transmitted. It may also be determined not to send slot-based PUCCH 0 before sending slot-based PUCCH 0.

Application example two

The terminal device is configured to generate two feedback codebooks, feedback codebook 0 and feedback codebook 1. The two feedback codebooks have different priorities, corresponding to priority numbers 0 and 1, respectively, where 1 represents high priority, and 0 Represents low priority. Feedback codebook 0 is transmitted through slot-based PUCCH 0, and feedback codebook 1 is transmitted through sub-slot-based PUCCH 1.

As shown in Figure 4, the terminal device first receives the PDSCH 0 and determines that its corresponding feedback information (ie ACK/NACK information) is transmitted in the first time slot, and the priority of the corresponding feedback codebook 0 is low priority. That is, the priority of the corresponding slot-based PUCCH 0 is also low priority. Then, the terminal device receives the PDSCH 1 again, and determines that the corresponding feedback information is also transmitted in the word time slot in the first time slot. The priority of the corresponding feedback codebook 1 is high priority, that is, the corresponding sub- The priority of slot-based PUCCH 1 is also high priority. Regardless of whether slot-based PUCCH 0 and sub-slot-based PUCCH 1 overlap in the time domain, the terminal device does not transmit slot-based PUCCH 0.

The terminal device can stop generating the sub-slot-based PUCCH 1 after it is determined to send the sub-slot-based PUCCH 1 (the terminal device can know to send the sub-slot-based PUCCH 1 after receiving the PDSCH 1 or receiving the downlink control signaling for scheduling the PDSCH 1) Feed back codebook 0 or stop preparing slot-based PUCCH 0, so that slot-based PUCCH 0 is not transmitted. It may also be determined not to send slot-based PUCCH 0 before sending slot-based PUCCH 0.

Application example three

As shown in Figure 5, both slot-based PUCCH 0 and slot-based PUCCH 1 are used to carry the feedback codebook. The priority of slot-based PUCCH 0 is low priority, and the priority of slot-based PUCCH 1 High priority. The terminal device determines to transmit slot-based PUCCH 1 in the first time slot, and does not transmit slot-based PUCCH 0. In the first time slot, the terminal device determines a high-priority multiplexed channel for the high-priority channel (ie, slot-based PUCCH 1, high-priority channel 1, and high-priority channel 2). Since the low-priority channel has only low-priority channel 1, it is no longer necessary to determine the low-priority multiplexed channel.
