Taking the communication system 100 shown in fig. 1 as an example, the communication device may include a network device 110 and a terminal 120 having a communication function, and the network device 110 and the terminal 120 may be the specific devices described above and are not described again here; the communication device may also include other devices in the communication system 100, such as other network entities, for example, a network controller, a mobility management entity, and the like, which are not limited in this embodiment.

It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

In order to facilitate 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.

In 5G NR Rel-15 it is specified that only one PUCCH carrying ACK/NACK information can be transmitted in a slot, this PUCCH being called slot-based PUCCH. One slot-based PUCCH may occupy all or part of the time domain resources within one slot. If the ACK/NACK information of the multiple downlink channels is transmitted through one slot, the ACK/NACK information of the multiple downlink channels is multiplexed and transmitted through one slot-based PUCCH.

For an Ultra-high-reliable low-delay (URLLC) service in Rel-16, in order to meet the requirement of short delay, ACK/NACK feedback based on sub-slots is further supported. At this time, a time interval between a Physical Downlink Shared Channel (PDSCH) and a PUCCH (sub-slot-based PUCCH) transmitting corresponding ACK/NACK information is determined using a sub-slot as a resource element, and such a PUCCH is referred to as a sub-slot-based PUCCH. One sub-slot-based PUCCH can only occupy time domain resources in one sub-slot for transmission, namely the sub-slot-based PUCCH cannot transmit across the sub-slots. The time domain resource of the sub-slot may include 2 symbols or 7 symbols, and a plurality of sub-slot-based PUCCHs carrying ACK/NACK information may be transmitted in one slot.

In addition, NR Rel-16 may simultaneously construct two HARQ-ACK feedback codebooks (codebooks) for terminal devices supporting different types of services, and the HARQ-ACK feedback codebooks are simply referred to as feedback codebooks in the following description. The two feedback codebooks correspond to different priorities (priority number 0 is low priority, and priority number 1 is high priority), respectively. The priority information of the PUCCH bearing the feedback codebook is the same as the priority information corresponding to the feedback codebook. Two feedback codebooks may be configured to transmit over slot-based PUCCH or sub-slot-based PUCCH, respectively, that is:

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

● Both feedback codebooks are transmitted through slot-based PUCCHs; or,

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

Note that the feedback codebook transmitted via the slot-based PUCCH may also be referred to as a "slot-based codebook". For a feedback codebook transmitted over a sub-slot-based PUCCH, it may also be referred to as a "sub-slot-based codebook".

When the terminal equipment supports two feedback codebooks, the two feedback codebooks respectively correspond to different priorities, and the priority information of the PUCCH bearing the feedback codebooks is the same as the priority information corresponding to the feedback codebooks. The priority information may also be applied to other uplink channels, that is, each uplink channel of the terminal device has corresponding priority information. The terminal equipment needs to send a plurality of uplink channels in a time slot, and if the time domains of the plurality of uplink channels with the same priority are overlapped, the terminal equipment determines a multiplexing channel for the priority for transmitting information carried in all the channels with the priority. Because the two feedback codebooks are respectively corresponding to the two priorities, two multiplexing channels to be transmitted can be obtained, and the two multiplexing channels to be transmitted are respectively corresponding to different priorities. If the time domains of the two multiplexing channels to be transmitted are overlapped, only the multiplexing channel with high priority is transmitted. And if the time domains of the two multiplexing channels to be transmitted are not overlapped, respectively transmitting the two multiplexing channels to be transmitted.

The 3GPP defines that only one slot-based PUCCH carrying ACK/NACK information can be transmitted in one slot. However, as can be seen from the above description, when the terminal device supports two feedback codebooks for carrying ACK/NACK information and at least one feedback codebook is transmitted through the slot-based PUCCH, it may occur that a plurality of PUCCHs carrying ACK/NACK information are transmitted in one slot and at least one slot-based PUCCH is included in the plurality of PUCCHs, which is contrary to the constraint of the slot-based PUCCH, thereby increasing the processing complexity of the terminal device. Therefore, the following technical scheme of the embodiment of the application is provided.

Fig. 2 is a flowchart illustrating an uplink control information transmission method provided in an embodiment of the present application, where as shown in fig. 2, the uplink control information transmission method includes the following steps:

step 201: the method comprises the steps that terminal equipment receives first configuration information, wherein the first configuration information is used for indicating the terminal equipment to generate at least two feedback codebooks, and the at least two feedback codebooks comprise a first feedback codebook and a second feedback codebook.

In this embodiment, a terminal device receives first configuration information sent by a network device, where the network device may be a base station, such as a gbb.

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

It should be noted that, in the embodiment of the present application, the at least two feedback codebooks include two feedback codebooks for an example, but not limited to this, the at least two feedback codebooks may further include a greater number of feedback 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: under the condition that the terminal equipment determines to construct the first feedback codebook and/or the terminal equipment determines to send a first PUCCH bearing the first feedback codebook, the terminal equipment determines not to construct the second feedback codebook and/or the terminal determines not to transmit a second PUCCH bearing the second feedback codebook; wherein the first PUCCH and the second PUCCH are both located in a first slot.

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

In this embodiment of the present application, if the terminal device determines to construct the first feedback codebook and/or the terminal device determines to send the first PUCCH bearing the first feedback codebook, the terminal device determines not to construct the second feedback codebook and/or the terminal determines not to transmit the second PUCCH bearing the second feedback codebook. The following describes in detail the technical solution of the embodiment of the present application with reference to specific implementations of the first PUCCH and the second PUCCH.

● The first condition is as follows: the first PUCCH is a slot-based PUCCH (slot-based PUCCH); the second PUCCH is slot-based PUCCH (slot-based PUCCH) or sub-slot-based PUCCH (sub-slot-based PUCCH).

In an embodiment of the present application, the priority number of the first feedback codebook is a first number, where the first number is used to indicate that the priority of the first feedback codebook is a first priority (e.g., a high priority). Further, optionally, the first number is, for example, 1.

For this situation, the terminal device determines to construct the first feedback codebook and/or the terminal device determines to send a first PUCCH carrying the first feedback codebook, and the terminal device determines not to construct a feedback codebook other than the first feedback codebook in the at least two feedback codebooks and/or the terminal device determines not to transmit a second PUCCH for carrying a feedback codebook other than the first feedback codebook in the at least two feedback codebooks.

In an example, taking the at least two feedback codebooks include two feedback codebooks, a feedback codebook other than the first feedback codebook in the at least two feedback codebooks is the second feedback codebook.

Note that in the present embodiment, the description of "not constructed" may be equivalently replaced with "skip (skip) construction", or "drop (drop) construction", or "stop (stop) construction", or "undesired (is not expected) construction".

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

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

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

In the foregoing scheme, optionally, the PUCCH based on slot has one of the following features:

the time domain unit of the PUCCH based on the time slot is the time slot;

at most one of the slot-based PUCCHs is included in one slot, and the slot-based PUCCH is used for carrying a feedback codebook;

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

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

In the foregoing scheme, optionally, the sub-slot-based PUCCH has one of the following characteristics:

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

the sub-slot-based PUCCH is used for carrying a feedback codebook and comprises a plurality of sub-slot-based PUCCHs in one slot;

the maximum time domain length of the PUCCH based on the sub-slot 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;

and 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 are not overlapped, since the first PUCCH and the second PUCCH belong to the same slot, the terminal device may also select not to transmit a low priority channel therein, and it is ensured that at most one high priority slot-based PUCCH carrying a feedback codebook can be provided in one slot, thereby simplifying the processing complexity of the terminal device.

In an optional manner, under a condition that the terminal device determines not to construct the second feedback codebook and/or the terminal determines not to transmit a second PUCCH carrying the second feedback codebook, the terminal device determines a multiplexing channel according to at least one uplink channel, where any one of all channels included by the at least one uplink channel and the second PUCCH overlaps with at least one other channel of all channels, and a priority of the at least one uplink channel is the same as a priority of the second PUCCH.

For example: for the first time slot, the terminal device needs to transmit an uplink channel 1, an uplink channel 2, and an uplink channel 3, the priorities of the 3 channels are the same, and one channel among the 3 channels overlaps with one or two other channels, so that the terminal device determines the multiplexing channel according to the uplink channel 1 and the uplink channel 3 when determining that the uplink channel 2 is not transmitted (the channel is a PUCCH carrying a feedback codebook).

It should be noted that, if the terminal device determines that the second feedback codebook is not constructed and/or a second PUCCH carrying the second feedback codebook is not transmitted, the second PUCCH does not participate in the process of determining the multiplexing channel of the channel with the same priority. Here, the terminal device determining not to construct the second feedback codebook may be equivalently understood as the terminal device not transmitting the second PUCCH. The terminal equipment determines not to transmit the second PUCCH first and then determines the multiplexing channel with the same priority, so that the channel multiplexing processing on the second PUCCH can be avoided, namely, the action of determining not to transmit a certain PUCCH carrying a feedback codebook is before the action of determining the multiplexing channel, so that the unnecessary action of channel multiplexing processing can be avoided.

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

The technical solutions of the embodiments of the present application are illustrated below with reference to specific application examples.

Application example 1

The terminal equipment is configured to generate two feedback codebooks, namely a feedback codebook 0 and a feedback codebook 1, wherein the priorities of the two feedback codebooks are different and respectively correspond to

priority numbers

0 and 1, wherein 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 fig. 3, the terminal device first receives PDSCH 0, determines that its corresponding feedback information (i.e., ACK/NACK information) is transmitted in the first slot, and the priority of its corresponding feedback codebook 0 is low priority, i.e., the priority of its corresponding slot-based PUCCH 0 is also low priority. Then, the terminal device receives the PDSCH 1 again, determines that the corresponding feedback information is also transmitted in the first slot, and determines that the priority of the corresponding feedback codebook 1 is high priority, that is, the priority of the corresponding slot-based PUCCH 1 is also high priority. Although slot-based PUCCH 0 and slot-based PUCCH 1 are both slot-based PUCCH, time domain resources actually occupied by the two are not overlapped. The terminal device still does not transmit slot-based PUCCH 0.

The terminal device may stop generating the feedback codebook 0 or stop preparing the slot-based PUCCH 0 after determining that the slot-based PUCCH 1 is to be transmitted (the terminal device may know that the slot-based PUCCH 1 is to be transmitted when receiving the PDSCH 1 or receiving a downlink control signaling for scheduling the PDSCH 1), so as to implement non-transmission of the slot-based PUCCH 0. It may also be determined not to transmit slot-based PUCCH 0 just before transmitting slot-based PUCCH 0.

Application example two

priority numbers

0 and 1, wherein 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 sub-slot-based PUCCH 1.

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

The terminal device may stop generating the feedback codebook 0 or stop preparing the slot-based PUCCH 0 after determining that the sub-slot-based PUCCH 1 is to be transmitted (the terminal device may know that the sub-slot-based PUCCH 1 is to be transmitted by receiving the PDSCH 1 or by receiving a downlink control signaling for scheduling the PDSCH 1), so as to implement not transmitting the slot-based PUCCH 0. It may be determined not to transmit the slot-based PUCCH 0 only before transmitting the slot-based PUCCH 0.

Application example three

As shown in fig. 5, slot-based PUCCH 0 and slot-based PUCCH 1 are both used for carrying a feedback codebook, where the priority of slot-based PUCCH 0 is low priority, and the priority of slot-based PUCCH 1 is high priority. And the terminal equipment determines to transmit slot-based PUCCH 1 in the first slot and not to transmit slot-based PUCCH 0. Then in the first slot, the terminal device determines a high-priority multiplexing channel for the high-priority channels (i.e. slot-based PUCCH 1, high-priority channel 2). Since the low priority channel is only low priority channel 1, it is no longer necessary to determine the low priority multiplexed channel.

Fig. 6 is a schematic structural composition diagram of an uplink control information transmission apparatus provided in an embodiment of the present application, and is applied to a terminal device, as shown in fig. 6, the uplink control information transmission apparatus includes:

a receiving unit 601, configured to receive first configuration information, where the first configuration information is used to instruct the terminal device to generate at least two feedback codebooks, where the at least two feedback codebooks include a first feedback codebook and a second feedback codebook;
