Detailed Description

In the embodiment of the invention, the term "and/or" describes the association relation of the association objects, which means that three relations can exist, for example, a and/or B can be expressed as follows: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

The term "plurality" in the embodiments of the present application means two or more, and other adjectives are similar thereto.

The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

The embodiment of the application provides an uplink control information transmission method, device and equipment, which are used for solving the problem of multiplexing UCI with different priorities on one PUCCH transmission resource.

The method and the device are based on the same application, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.

In order for those skilled in the art to better understand the methods of embodiments of the present invention, the following description is presented.

In a 5G NR (New Radio) communication system, considering that uplink time domain resources in one slot are limited, there may be a case where PUCCH transmission resources of multiple UCI overlap in the time domain. When there is overlap in PUCCH transmission resources of different types of UCI, UCI combination transmission is required to avoid parallel transmission of multiple PUCCHs on the same carrier.

At present, only UCIs of the same physical layer are supported for multiplexing transmission, when PUCCH transmission resources of UCIs of different physical layer priorities are overlapped on a time domain, only UCIs of high priority are transmitted, and UCIs of low priority are discarded. How to multiplex UCI with different priorities into one PUCCH transmission resource to ensure transmission performance of UCI with different priorities becomes a problem to be solved.

Based on this, as shown in fig. 1, a flow chart of an information transmission method according to an embodiment of the present invention is provided, where the method is applied to a terminal, and the method may include:

step 101: multiplexing the first HARQ-ACK, the second HARQ-ACK and the SR into the same target PUCCH transmission resource by a terminal based on the PUCCH format of the first HARQ-ACK and/or the transmission state of the SR under the condition that the first HARQ-ACK, the second HARQ-ACK and the SR meet the multiplexing transmission condition, wherein the priority of the first HARQ-ACK is higher than that of the second HARQ-ACK;

here, the first HARQ-ACK is carried in a first uplink control information UCI, the second HARQ-ACK is carried in a second UCI, and the SR is carried in a third UCI.

In this step, in case it is determined that the high-priority HARQ-ACK (first HARQ-ACK) and the low-priority HARQ-ACK (second HARQ-ACK) and the SR satisfy the multiplexing transmission condition, that is, in case it is determined that the high-priority HARQ-ACK (first HARQ-ACK) and the low-priority HARQ-ACK (second HARQ-ACK) and the SR need multiplexing transmission, the high-priority HARQ-ACK (first HARQ-ACK) and the low-priority HARQ-ACK (second HARQ-ACK) and the SRUCI are multiplexed on the same PUCCH transmission resource based on the transmission state of the PUCCH format and/or the SR of the high-priority HARQ-ACK, so that UCI corresponding to the low-priority HARQ-ACK can not be discarded, thereby ensuring transmission performance of UCI of different priorities.

Step 102: and the terminal sends the first HARQ-ACK, the second HARQ-ACK and the SR to network equipment through the target PUCCH transmission resource.

Here, the network device may be a base station. Specifically, since the first HARQ-ACK is carried in the first uplink control information UCI, the second HARQ-ACK is carried in the second UCI, the SR is carried in the third UCI, and the terminal sends the first UCI, the second UCI and the third UCI to the network device through the target PUCCH transmission resource.

It should be noted that, in the embodiment of the present invention, the SR is a high priority SR.

According to the information transmission method of the embodiment of the invention, under the condition that the first HARQ-ACK, the second HARQ-ACK and the scheduling request SR meet multiplexing transmission conditions, a terminal multiplexes the first HARQ-ACK, the second HARQ-ACK and the SR in the same target PUCCH transmission resource based on the PUCCH format of the first HARQ-ACK and/or the transmission state of the SR, wherein the priority of the first HARQ-ACK is higher than that of the second HARQ-ACK; and sending the first HARQ-ACK, the second HARQ-ACK and the SR to the network equipment through the target PUCCH transmission resource, so that UCIs with different priorities can be multiplexed on the same PUCCH transmission resource, and the transmission performance of the UCIs with different priorities is ensured.

Optionally, the multiplexing transmission condition includes one of the following:

here, the situation may be referred to as overlapping the PUCCH transmission resources shown in fig. 2 in the time domain. That is, UCI of different priorities is multiplexed respectively, and there is a time-domain overlap between the transmission resources corresponding to the UCI of each priority after multiplexing. For example, as shown in fig. 2, the PUCCH transmission resource corresponding to the 1-bit high-priority HP HARQ-ACK and the PUCCH transmission resource corresponding to the 1-bit low-priority LP HARQ-ACK overlap each other in time domain in the transmission resource corresponding to each UCI multiplexing of each priority.

In the above three cases, the PUCCH transmission resources corresponding to those shown in fig. 3 to 5 overlap in the time domain. For example, a PUCCH resource carrying a 1-bit high priority HARQ-ACK overlaps with a PUCCH resource carrying a high priority SR in the time domain, and a PUCCH resource carrying a high priority SR overlaps with a PUCCH resource carrying a 1-bit low priority HARQ-ACK in the time domain.

Optionally, according to the principle of multiplexing channels with the same priority, selecting the channel with the earliest ending position, and multiplexing all channels with the starting position before the ending position as a whole.

For the case in fig. 3/4/5, first, the first two channels are taken to determine the multiplexing result according to the multiplexing rule of two channels, for example, the PUCCH transmission resource of the second HARQ-ACK and the PUCCH transmission resource of the SR are taken to determine the multiplexing result according to the multiplexing rule of two channels, that is, the PUCCH transmission resource carrying the second HARQ-ACK and the SR, and then, the PUCCH transmission resource carrying the second HARQ-ACK and the SR overlaps with the PUCCH transmission resource of the first HARQ-ACK in the time domain.

This situation can be seen in fig. 3.

Here, the PUCCH transmission resource corresponding to the SR overlaps with the PUCCH transmission resource corresponding to the first HARQ-ACK in a time domain, and the PUCCH transmission resource corresponding to the first HARQ-ACK overlaps with the PUCCH transmission resource corresponding to the second HARQ-ACK in a time domain, which may be referred to as fig. 4.

The PUCCH transmission resource corresponding to the SR overlaps with the PUCCH transmission resource corresponding to the second HARQ-ACK in the time domain, and the PUCCH transmission resource corresponding to the first HARQ-ACK overlaps with the PUCCH transmission resource corresponding to the second HARQ-ACK in the time domain, which may be seen in fig. 5.

As an optional implementation manner, the PUCCH format of the first HARQ-ACK is PUCCH format 0; the target PUCCH transmission resource is a PUCCH transmission resource corresponding to the first HARQ-ACK, wherein the first HARQ-ACK, the second HARQ-ACK and the SR are multiplexed on the PUCCH transmission resource corresponding to the first HARQ-ACK, and different feedback states of the first HARQ-ACK, the second HARQ-ACK and the SR are represented by different cyclic shifts.

This implementation is specifically described below with respect to an embodiment.

Referring to fig. 2, assuming that a PUCCH resource carrying a 1-bit high priority HARQ-ACK overlaps a PUCCH resource carrying a 1-bit low priority HARQ-ACK and a PUCCH resource carrying a high priority SR, it is determined that the high priority HARQ-ACK and the low priority HARQ-ACK and the high priority SR are multiplexed on the same PUCCH resource for transmission.

Specifically, the high priority HARQ-ACK, the low priority HARQ-ACK, and the high priority SR are multiplexed on which PUCCH resource, and the PUCCH format determination based on the high priority HARQ-ACK is performed.

Wherein, the high priority HARQ-ACK uses PUCCH format 0, the low priority HARQ-ACK uses PUCCH format 0 or PUCCH format 1, and the high priority SR uses PUCCH format 0 or PUCCH format 1.

In this case, the high priority HARQ-ACK, the low priority HARQ-ACK, and the high priority SR are multiplexed on PUCCH resources corresponding to the high priority HARQ-ACK, and different feedback states of the high priority HARQ-ACK, the low priority HARQ-ACK, and the high priority SR are represented by different cyclic shifts, specifically, as shown in table 1:

TABLE 1

As an optional implementation manner, the PUCCH format of the first HARQ-ACK is PUCCH format 1; the target PUCCH transmission resource is the PUCCH transmission resource of two PUCCH formats 1 corresponding to the first HARQ-ACK;

As an optional implementation manner, the PUCCH format of the first HARQ-ACK is PUCCH format 0 or PUCCH format 1;

specifically, the first PUCCH transmission resource is a PUCCH transmission resource that is preconfigured and used for multiplexing transmission, or the first PUCCH transmission resource is a PUCCH transmission resource determined based on the PUCCH transmission resource corresponding to the first HARQ-ACK.

Here, the first PUCCH transmission resource is a PUCCH transmission resource determined based on a PUCCH transmission resource corresponding to the first HARQ-ACK, and specifically may be: the first PUCCH transmission resource is: the corresponding PUCCH number differs from the PUCCH number based on the PUCCH transmission resource corresponding to the first HARQ-ACK by 1, and the PUCCH transmission resource of PUCCH format 1.

Here, when the SR is a positive SR, the target PUCCH transmission resource is a PUCCH transmission resource corresponding to the SR, and a specific optional implementation manner is:

when the SR is a positive SR and the PUCCH format of the positive SR is 0, multiplexing the positive SR, the first HARQ-ACK, and the second HARQ-ACK on PUCCH transmission resources corresponding to the SR, wherein different feedback states of the first HARQ-ACK and the second HARQ-ACK are represented by different cyclic shifts;

Specifically, the high priority HARQ-ACK, the low priority HARQ-ACK, and the high priority SR are multiplexed on which PUCCH resource, and are determined based on the transmission status of the SR.

The high priority HARQ-ACK uses PUCCH format 0 or PUCCH format 1, the low priority HARQ-ACK uses PUCCH format 0 or PUCCH format 1, and the high priority SR uses PUCCH format 0 or PUCCH format 1.

When the SR is a positive SR, 2-bit HARQ-ACK information is transmitted on a first PUCCH resource;

it should be noted that 2-bit HARQ-ACK information is obtained by concatenating 1-bit high-priority HARQ-ACK and 1-bit low-priority HARQ-ACK.

Optionally, the first PUCCH resource is a PUCCH resource configured by a network device (such as a base station) and used for multiplexing transmissions. In this embodiment, the first PUCCH resource uses PUCCH format 1.

Optionally, the first PUCCH resource is determined based on a PUCCH resource corresponding to the high priority HARQ-ACK.

For example, if the PUCCH resource number of the high priority HARQ-ACK is x, the first PUCCH resource is the PUCCH resource number x+1.

Or when the SR is a positive SR, transmitting 2-bit HARQ-ACK information on a PUCCH resource corresponding to the SR.

Specifically, when the SR is a positive SR and the SR uses PUCCH format 0, 2-bit HARQ-ACK information is transmitted through 4 cyclic shifts on a PUCCH resource corresponding to the SR.

For example, on PUCCH RB resources corresponding to SRs, different HARQ-ACK feedback information is represented by different cyclic shifts in table 2 below.

TABLE 2

When the SR is a positive SR and the SR uses PUCCH format 1, 2-bit HARQ-ACK information is transmitted through 1 modulation symbol on a PUCCH resource corresponding to the SR.

Based on this, as an optional implementation manner, in the case where the SR is a negative SR and the PUCCH format of the first HARQ-ACK is PUCCH format 0, the first HARQ-ACK and the second HARQ-ACK are multiplexed on PUCCH transmission resources corresponding to the first HARQ-ACK, and different feedback states of the first HARQ-ACK and the second HARQ-ACK are represented by different cyclic shifts;

Specifically, the high priority HARQ-ACK, the low priority HARQ-ACK, and the high priority SR are multiplexed on which PUCCH resource, and are determined based on the PUCCH transmission resource of the high priority HARQ-ACK and the transmission state of the SR.

Wherein, the high priority HARQ-ACK uses PUCCH format 0 or PUCCH format 1, the low priority HARQ-ACK uses PUCCH format 0 or PUCCH format 1, and the high priority SR uses PUCCH format 0 or PUCCH format 1.

When the SR is a negative SR and the high priority HARQ-ACK uses PUCCH format 0, 2-bit HARQ-ACK information is transmitted through 4 cyclic shifts on PUCCH resources corresponding to the high priority HARQ-ACK, as shown in table 3;

TABLE 3 Table 3

When the SR is a negative SR and the high priority HARQ-ACK uses PUCCH format 1, 2-bit HARQ-ACK information is transmitted through 1 modulation symbol on the PUCCH resource corresponding to the high priority HARQ-ACK.

As an alternative implementation, the number of SRs is at least two;

Here, the situation corresponding to this implementation may be seen in fig. 6, that is, the PUCCH transmission resource carrying the first HARQ-ACK, the PUCCH transmission resource carrying the second HARQ-ACK, and the PUCCH transmission resources carrying the SRs overlap in the time domain.

Here, one SR is selected from at least two SRs, and it should be noted that the selected SR is a high priority SR, and a low priority SR may be discarded by the terminal.

Referring to fig. 6, assuming that PUCCH resources carrying 1-bit high-priority HARQ-ACK overlap PUCCH resources carrying 1-bit low-priority HARQ-ACK and PUCCH resources carrying multiple SRs, it is determined that the high-priority HARQ-ACK and the low-priority HARQ-ACK and the SRs are multiplexed on the same PUCCH resource for transmission. Specifically, the terminal needs to select one of the plurality of SRs and the HARQ-ACK to perform multiplexing transmission, and because there are SRs with different priorities at the same time, the terminal may discard the SR4 with low priority, and select one of the SRs 1/2/3 with high priority and the HARQ-ACK to perform multiplexing transmission, and the specific multiplexing method may be referred to the above embodiment section and will not be repeated here.

It should be noted that, in the embodiment of the present invention, a multiplexing manner is that, for the channel collision cases with different priorities as a whole, the collision cases shown in fig. 3/4/5 are some special cases (similar, may also include the case of exchanging the front and rear sequences of the non-overlapping channels in the above-mentioned figures), and for all the above-mentioned special collision cases, it is considered that the case that 1-bit high-priority HARQ-ACK and 1-bit low-priority HARQ-ACK and SR need to be multiplexed on the same PUCCH resource is required, and in the embodiment of the present invention, the specific multiplexing method will not be described herein in detail.

Another multiplexing manner is to select, as a whole, a channel with the earliest end position according to a rule when channels with different priorities are multiplexed, and find all channels with initial positions before the end position as a whole for multiplexing, and for the case in fig. 3/4/5, first two channels are taken to determine a multiplexing result according to a multiplexing rule of two channels, and if the determined multiplexing resource collides with a third channel, the multiplexing method of multiplexing the first HARQ-ACK, the second HARQ-ACK and the SR in the same target PUCCH transmission resource is based on the determined multiplexing resource and the third channel in the embodiment of the present invention, which is not described here again.

It may also be that channels with different priorities are multiplexed respectively, and then whether the channels after each priority multiplexing collide is checked, if the channel after each priority multiplexing collides with the PUCCH resources of the 1-bit high priority HARQ-ACK, the 1-bit low priority HARQ-ACK and the SR, in the embodiment of the present invention, the multiplexing method of multiplexing the first HARQ-ACK, the second HARQ-ACK and the SR in the same target PUCCH transmission resource is not repeated here.

Fig. 7 is a schematic flow chart of an information transmission method according to an embodiment of the present invention, where the method is applied to a network device, and the method may include:

step 701: under the condition that the first HARQ-ACK, the second HARQ-ACK and the scheduling request SR meet multiplexing transmission conditions, the network equipment receives the first HARQ-ACK, the second HARQ-ACK and the SR which are sent by a terminal through target PUCCH transmission resources; wherein the priority of the first HARQ-ACK is higher than the priority of the second HARQ-ACK, and the first HARQ-ACK, the second HARQ-ACK and the SR are multiplexed on the target PUCCH transmission resource based on the PUCCH format of the first HARQ-ACK and/or the transmission state of the SR.

In this step, the network device may be a base station.

In the embodiment of the invention, the SR is a high priority SR.

Note that, the first HARQ-ACK is carried in the first uplink control information UCI, the second HARQ-ACK is carried in the second UCI, and the SR is carried in the third UCI.

Because the first HARQ-ACK is carried in the first uplink control information UCI, the second HARQ-ACK is carried in the second UCI, and the SR is carried in the third UCI, the network device receives the first UCI, the second UCI, and the third UCI sent by the terminal through the target PUCCH transmission resource.

Here, first, in case that it is determined that a first hybrid automatic repeat request acknowledgement HARQ-ACK, a second HARQ-ACK, and a scheduling request SR satisfy a multiplexing transmission condition, a network device determines a target PUCCH transmission resource for multiplexing transmission of the first HARQ-ACK, the second HARQ-ACK, and the SR based on a PUCCH format of the first HARQ-ACK and/or a transmission state of the SR; and then, receiving the first HARQ-ACK, the second HARQ-ACK and the SR sent by the terminal on a target PUCCH transmission resource.

According to the information transmission method, under the condition that the first HARQ-ACK, the second HARQ-ACK and the scheduling request SR meet multiplexing transmission conditions, the network equipment receives the first HARQ-ACK, the second HARQ-ACK and the SR which are sent by a terminal through target PUCCH transmission resources; the priority of the first HARQ-ACK is higher than the priority of the second HARQ-ACK, and the first HARQ-ACK, the second HARQ-ACK and the SR are multiplexed on the target PUCCH transmission resource based on the PUCCH format of the first HARQ-ACK and/or the transmission status of the SR, so that UCI with different priorities multiplexed on the same PUCCH transmission resource can be received, thereby ensuring transmission performance of UCI with different priorities.

Optionally, the PUCCH format of the first HARQ-ACK is PUCCH format 0; the target PUCCH transmission resource is a PUCCH transmission resource corresponding to the first HARQ-ACK, wherein the first HARQ-ACK, the second HARQ-ACK and the SR are multiplexed on the PUCCH transmission resource corresponding to the first HARQ-ACK, and different feedback states of the first HARQ-ACK, the second HARQ-ACK and the SR are represented by different cyclic shifts.

As an alternative implementation manner, the PUCCH format of the first HARQ-ACK is PUCCH format 1; the target PUCCH transmission resource is the PUCCH transmission resource of two PUCCH formats 1 corresponding to the first HARQ-ACK;
