Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and apparatus for transmitting uplink control information, a device, and a storage medium.

Background

Ultra-Reliable Low-latency communication (URLLC) service is defined in the fifth-generation mobile communication (5th Generation,5G) technology, and higher requirements are put on the reliability and latency characteristics of service data transmission.

For better support of URLLC services, in Release 16 (R16) of the third generation partnership project (3 rd Generation Partnership Project), a priority level policy is introduced for uplink control information (Uplik Control Information, UCI). Specifically, when physical uplink control channels (Physical Uplink Control CHannel, PUCCH) carrying UCI with different priorities overlap on time domain resources, the terminal device may preferentially guarantee transmission of UCI with a high priority, that is, the terminal device only transmits UCI with a high priority, and discard UCI with a low priority.

In order to reduce the impact of discarding low-priority UCI on system efficiency, 3GPP Release 17 discusses supporting multiplexing transmission of UCI with different priorities overlapping time domain resources. However, there is no clear method for multiplexing UCI with different priorities.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail with reference to the accompanying drawings, which are provided for reference only and are not intended to limit the embodiments of the present application.

It should be noted that the terms "first," "second," and the like in the description and the claims of the present application and the above figures are used for distinguishing between different objects and not for describing a particular sequential order. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.

Before describing embodiments of the present application in further detail, the terms and terminology involved in the embodiments of the present application will be described, and the terms and terminology involved in the embodiments of the present application will be used in the following explanation.

1) PUCCH format.

In practical applications, the PUCCH is used to carry uplink control information, i.e., UCI. UCI may include HARQ feedback information, SR information, and channel state information (Channel state information, CSI).

UCI carried on PUCCH has multiple formats. Referring to table 1, PUCCH format 0 and PUCCH format 1 may each carry 1-bit or 2-bit UCI information. Differently, PUCCH format 0 may occupy a maximum of 2 time domain symbols, while PUCCH format 1 may occupy 4-14 time domain symbols.

TABLE 1

PUCCH format	Number of time domain symbols	Number of bearer UCI bits	Physical resource block number
0	1–2	≤2	1
1	4–14	≤2	1
2	1–2	>2	1-16
3	4–14	>2	1-16
4	4–14	>2	1

In practice, PUCCH format 0 and PUCCH format 1 use cyclically shifted sequences in the frequency domain. Wherein UCI carried in PUCCH format 0 is determined by the selected cyclic shift offset (m _cs ) To implicitly indicate.

Specifically, when the terminal device transmits HARQ feedback information using PUCCH format 0, an initial sequence used for transmission may be determined according to indication information of the network device. Meanwhile, the terminal device can determine the cyclic shift offset (m according to the specific content of the HARQ feedback information _cs ). In this way, the terminal device can superimpose the above m on the basis of the determined initial sequence _cs And obtaining a final transmission sequence. Correspondingly, the network device can determine m used by the terminal device according to the received transmission sequence _cs . Further, the network device may determine m according to the correspondence between HARQ feedback information and the cyclic shift offset _cs Specific content of the corresponding HARQ feedback information.

Here, the correspondence relationship between HARQ feedback information and cyclic shift offset may be referred to as shown in tables 2 and 3. Wherein, table 2 shows a correspondence relationship between HARQ feedback information and a cyclic shift offset when 1-bit HARQ feedback information is transmitted through PUCCH format 0. Table 3 shows a correspondence relationship between HARQ feedback information and a cyclic shift offset when 2-bit HARQ feedback information is transmitted through PUCCH format 0.

TABLE 2

HARQ feedback information	0	1
Cyclic shift offset	m _CS ＝0	m _CS ＝6

TABLE 3 Table 3

HARQ feedback information	{0,0}	{0,1}	{1,1}	{1,0}
Cyclic shift offset	m _CS ＝0	m _CS ＝3	m _CS ＝6	m _CS ＝9

When the terminal device transmits SR information in PUCCH format 0, if the SR is positive (positive), that is, the terminal device has an uplink SR, the terminal device uses m _CS =0 determines the transmission sequence of PUCCH. If the SR is negative (negative), that is, the terminal device has no uplink SR, the terminal device does not transmit PUCCH.

In addition, UCI carried on PUCCH format 1 is modulated into a binary phase shift keying (Binary Phase Shift Keying, BPSK) or quadrature phase shift keying (Quadrature Phase Shift Keying, QPSK) modulation symbol d (0) first, and then multiplied by a base sequence to be mapped onto 12 subcarriers of a frequency domain, and spread in the time domain using an overlapped orthogonal code (orthogonal cover code, OCC).

When the terminal device transmits the HARQ feedback information using PUCCH format 1, the modulation symbol d (0) corresponding to the 1-bit or 2-bit HARQ feedback information may be multiplied to the cyclic shift sequence for transmission.

When the terminal device transmits SR information using PUCCH format 1, if SR is positive, PUCCH is transmitted. If the SR is negative, the terminal device does not transmit PUCCH.

2) Uplink control information multiplexing

The NR system does not support multiple PUCCHs for simultaneous transmission of UCI on uplink transmission, and when time domain resources of multiple PUCCHs overlap, uplink control information multiplexing is required. Currently, the following multiplexing rules are defined in Release 15 (R15):

rule 1: in the case that PUCCH1 carrying SR information and PUCCH2 carrying HARQ feedback information both adopt PUCCH format 0:

if the SR information is negative, the terminal equipment transmits HARQ feedback information through the PUCCH 2;

if the SR information is positive, the terminal equipment is located in the object of PUCCH2One PUCCH3 is transmitted within a physical resource block (Physical Resource Block, PRB). Wherein, cyclic shift offset (m _cs ) The determination may be based on the correspondence between HARQ feedback information and cyclic shift offset in the multiplexing scenario shown in table 4 or table 5.

Table 4 shows a correspondence relationship between HARQ feedback information and a cyclic shift offset when 1-bit HARQ feedback information and SR information are multiplexed and transmitted through PUCCH format 0. Table 5 shows a correspondence relationship between HARQ feedback information and a cyclic shift offset when 2-bit HARQ feedback information and SR information are multiplexed and transmitted through PUCCH format 0.

TABLE 4 Table 4

HARQ feedback information	0	1
Cyclic shift offset	m _CS ＝3	m _CS ＝9

TABLE 5

HARQ feedback information	{0,0}	{0,1}	{1,1}	{1,0}
Cyclic shift offset	m _CS ＝1	m _CS ＝4	m _CS ＝7	m _CS ＝10

Note that the cyclic shift offset corresponding to the HARQ feedback information in the multiplexing scenario is different from the cyclic shift offset (shown in tables 2 and 3) used when the HARQ feedback information is transmitted alone.

Rule 2: in the case that PUCCH1 carrying SR information adopts PUCCH format 0 and PUCCH2 carrying HARQ feedback information adopts PUCCH format 1, the terminal device transmits HARQ feedback information only through PUCCH2, and does not transmit SR information.

Rule 3: in the case that PUCCH format 1 is used for both PUCCH2 carrying SR information PUCCH1 and PUCCH carrying HARQ feedback information:

if the SR is positive, the terminal device transmits HARQ feedback information through PUCCH 1.

If the SR is negative, the terminal equipment transmits HARQ feedback information through the PUCCH 2.

Rule 4: when PUCCH1 carrying SR information adopts PUCCH format 1 and PUCCH2 carrying HARQ feedback information adopts PUCCH format 0, this is not supported. That is, the time domain resources occupied by PUCCH1 transmitting 1-bit SR information should not be shorter than the time delay resources occupied by PUCCH2 transmitting 1 or 2-bit HARQ feedback information.

R16 of the NR system introduces a UCI priority level strategy, and terminal equipment can preferentially guarantee the transmission of UCI with high priority level. However, discarding low priority UCI may adversely affect uplink traffic. For this reason, in the R17 version discussion, multiplexing transmission of UCI of different priorities overlapping time domain resources is supported. However, there is no clear method for multiplexing UCI with different priorities.

Based on this, the embodiment of the present application provides an uplink control information transmission method, specifically, after determining that a time domain resource of a first PUCCH carrying high priority information (i.e. first information) overlaps with a time domain resource of a second PUCCH carrying low priority information (i.e. second information), a terminal device or a network device may determine a third PUCCH based on a relationship between the number of time domain symbols included in the first PUCCH and the number of time domain symbols included in the second PUCCH, and send or receive at least one of the first information and the second information through the third PUCCH. That is, when the uplink control information with different priorities overlap in the time domain, a suitable third PUCCH may be selected to perform multiplexing transmission on the uplink control information with different priorities, thereby improving data transmission efficiency.

It should be understood that the terms "system" and "network" are used interchangeably herein. Herein, "first information" and "high priority information" may be used interchangeably, and "second information" and "low priority information" may be used interchangeably.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

The embodiment of the application provides an uplink control information transmission method, which can be applied to the communication system architecture shown in fig. 1. Specifically, referring to the flowchart shown in fig. 2, the uplink control information transmission provided in the embodiment of the present application may include the following steps:

in step 210, in the case of having the uplink SR, the terminal device transmits at least one of the first information and the second information through the third PUCCH.

Step 220, the network device receives at least one of the first information and the second information through the third PUCCH.

Here, the terminal device may transmit at least one of the first information and the second information to the network device through the third PUCCH.

Correspondingly, the network device receives at least one of the first information and the second information sent by the terminal device through the third PUCCH.

In the embodiment of the application, the third PUCCH is determined based on the relation between the number of time domain symbols included in the first PUCCH and the number of time domain symbols included in the second PUCCH; one of the first information and the second information is SR information, and the first PUCCH overlaps with the second PUCCH; the first PUCCH is a PUCCH which is preconfigured to bear first information, and the second PUCCH is a PUCCH which is preconfigured to bear second information; the second information has a lower priority than the first information.

Here, the first PUCCH overlaps with the second PUCCH, specifically, the time domain resource of the first PUCCH overlaps with the time domain resource of the second PUCCH. Here, the time domain resource overlapping may refer to that the time domain resource of the first PUCCH partially overlaps with the time domain resource of the second PUCCH, or may refer to that the time domain resource of the first PUCCH completely overlaps with the time domain resource of the second PUCCH, which is not limited in the present application.

In the embodiment of the application, the network device can pre-configure the corresponding PUCCH resource for each UCI, and indicate the PUCCH resource corresponding to each UCI to the terminal device through signaling. The signaling may be higher layer signaling or physical layer signaling, the higher layer signaling may be radio resource Control (Radio Resource Control, RRC) signaling or medium access Control (Medium Access Control, MAC) Control Element (CE), and the physical layer signaling may be downlink Control information (Downlink Control Information, DCI). The embodiment of the present application is not limited thereto.

That is, the terminal device may receive the signaling sent by the network device, and determine the first PUCCH corresponding to the first information and the second PUCCH corresponding to the second information through the configuration information included in the signaling.

In the embodiment of the application, the network device can also configure the corresponding priority for each UCI, and indicate the corresponding priority of each UCI to the terminal device through signaling. The signaling for configuring the PUCCH resource for UCI and the signaling for configuring the priority may be the same signaling or may be different signaling, which is not limited in the embodiment of the present application.

In the embodiment of the application, the priority is understood to be the transmission priority of the information, and the higher the priority of the information is, the higher the performance requirement of the information on transmission is. The performance requirements herein specifically refer to requirements for transmission reliability or requirements for delay, which are not limited by the embodiments of the present application.

In particular, the network device may assign different priorities to each UCI based on the requirements for information transmission performance. For example, if the first information is sensitive to latency, the network device may assign a high priority to the first information, and if the second information is not sensitive to latency, a low priority may be assigned to the second information.

In the embodiment of the present application, the first information and the second information are different, one of the first information and the second information may be SR information, and one of the first information and the second information may be HARQ feedback information.

Specifically, the first information is SR information, and the second information is HARQ feedback information;

or,

the first information is HARQ feedback information, and the second information is SR information.

In addition, in the embodiment of the present application, the situation that the terminal device does not expect that the time domain resources of one first PUCCH overlap with the time domain resources of the plurality of second PUCCHs occurs, where the time domain resources between the plurality of second PUCCHs do not overlap with each other. The number of the first PUCCH and the second PUCCH in the embodiment of the application is one. That is, the time domain resource of the first PUCCH overlaps with the time domain resource of the second PUCCH according to the embodiment of the present application, specifically, the time domain resource of one first PUCCH overlaps with the time domain resource of one second PUCCH.

It may be appreciated that, after determining that the time domain resource of the first PUCCH carrying the high priority information (i.e. the first information) overlaps with the time domain resource of the second PUCCH carrying the low priority information (i.e. the second information), the terminal device or the network device may determine the third PUCCH according to a relationship between the number of time domain symbols included in the first PUCCH and the number of time domain symbols included in the second PUCCH, and transmit or receive at least one of the first information and the second information through the third PUCCH. That is, when the uplink control information with different priorities overlap in the time domain, a suitable third PUCCH may be selected to perform multiplexing transmission on the uplink control information with different priorities, thereby improving data transmission efficiency.

In practical applications, the terminal device does not always have an uplink SR, i.e. the terminal device does not always have a need to send SR information. When the terminal device has an uplink SR, the SR is considered to be positive (i.e., positive). When the terminal device does not have an uplink SR, the SR is considered to be negative (i.e., negative).

In the embodiment of the present application, in the case of having an uplink SR, i.e., SR is positive, the terminal device may determine the third PUCCH according to a relationship between the number of time domain symbols included in the first PUCCH and the number of time domain symbols included in the second PUCCH.

In addition, in the case that the terminal device does not have an uplink SR, that is, the SR is negative, the terminal device may transmit only other information.

For example, the first PUCCH is preconfigured to carry SR information, and the second PUCCH is preconfigured to carry HARQ feedback information; the terminal device transmits the HARQ feedback information through the second PUCCH regardless of whether the SR information has a higher priority than the HARQ feedback information or lower priority than the HARQ feedback information.

Correspondingly, after determining that the first PUCCH and the second PUCCH overlap in the time domain, the network device may determine a third PUCCH based on the number of time domain symbols included in the first PUCCH and the number of time domain symbols included in the second PUCCH, and receive the first message and/or the second message on the third PUCCH.

In the embodiment of the present application, after determining that the PUCCH time domain resources of different priority information overlap, a third PUCCH may be determined according to a relationship between the number of time domain symbols included in the first PUCCH and the number of time domain symbols included in the second PUCCH, and at least one of the first information and the second information may be further transmitted through the third PUCCH.

The time domain symbol may be an orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbol or a single carrier frequency division multiplexing (Single Carrier Frequency Division Multiplexing, SC-FDM) symbol. The embodiment of the present application is not limited thereto.

Next, how to determine the third PUCCH based on a relationship between the number of time domain symbols included in the first PUCCH and the number of time domain symbols included in the second PUCCH is described in detail.

In an embodiment of the present application, if the number of time domain symbols included in the second PUCCH is greater than or equal to the number of time domain symbols included in the first PUCCH, the transmission resource of the third PUCCH is the same as the transmission resource of the second PUCCH.

Here, the third PUCCH may be used to transmit the first information and the second information.

That is, when the number of time domain symbols included in the preconfigured second PUCCH carrying low priority information is greater than or equal to the number of time domain symbols included in the preconfigured first PUCCH carrying high priority information, the terminal device may multiplex the first information and the second information using the same transmission resource as the second PUCCH. That is, the first information and the second information are transmitted using the same transmission resource of the second PUCCH.

Note that, in the embodiment of the present application, the PUCCH format of the first PUCCH is the same as the PUCCH format of the second PUCCH. Specifically, the PUCCH formats of the first PUCCH and the second PUCCH are PUCCH format 0 or PUCCH format 1.

It can be appreciated that PUCCH format 0 and PUCCH format 1 each occupy 1 PRB in the frequency domain resource, and the transmission reliability thereof is mainly affected by the number of time domain symbols (1 or 2). The longer the number of time domain symbols, the longer the PUCCH transmission is provided, contributing to an increase in coverage distance, and thus the higher the reliability of the transmission. Based on this, when the number of time domain symbols included in the second PUCCH corresponding to the second information of low priority is greater than or equal to the number of time domain symbols included in the first PUCCH corresponding to the first information of high priority, the first information and the second information are simultaneously transmitted using the same time-frequency resource as the second PUCCH carrying the low priority information, and the transmission reliability of the high priority information can be ensured.

In the embodiment of the present application, the transmission resource of the third PUCCH and the transmission resource of the second PUCCH may be the same in a plurality of ways, and two ways of these ways are described in detail below.

In a first possible implementation manner, the transmission resource of the third PUCCH is the same as the transmission resource of the second PUCCH, which may mean that the time domain resource occupied by the third PUCCH is the same as the time domain resource occupied by the second PUCCH, and the frequency domain resource occupied by the third PUCCH is the same as the frequency domain resource occupied by the second PUCCH.

Specifically, when the first information is SR information, the second information is HARQ feedback information, and the PUCCH formats of the first PUCCH and the second PUCCH are PUCCH format 0, the time domain resource occupied by the third PUCCH is the same as the time domain resource occupied by the second PUCCH, and the frequency domain resource occupied by the third PUCCH is the same as the frequency domain resource occupied by the second PUCCH.

That is, when the high priority information is SR information, the low priority information is HARQ feedback information, and the formats of PUCCHs carrying the SR information and the HARQ feedback information are PUCCH format 0, the terminal device may multiplex the SR information and the HARQ feedback information using the time domain resource and the frequency domain resource of the second PUCCH.

Here, the cyclic shift offset of the third PUCCH transmission sequence may be determined according to table 4 or table 5. Specifically, the terminal device may select a cyclic shift offset corresponding to a specific content of the HARQ feedback information from table 4 or table 5, and determine the third PUCCH transmission sequence.

In a second possible implementation manner, the transmission resource of the third PUCCH is the same as the transmission resource of the second PUCCH, which may mean that the time domain resource occupied by the third PUCCH is the same as the time domain resource occupied by the second PUCCH, the frequency domain resource occupied by the third PUCCH is the same as the frequency domain resource occupied by the second PUCCH, and the sequence resource occupied by the third PUCCH is the same as the sequence resource occupied by the second PUCCH.

Specifically, when the first information is HARQ feedback information, the second information is SR information, and the PUCCH formats of the first PUCCH and the second PUCCH are PUCCH format 1, the time domain resource occupied by the third PUCCH is the same as the time domain resource occupied by the second PUCCH, the frequency domain resource occupied by the third PUCCH is the same as the frequency domain resource occupied by the second PUCCH, and the sequence resource occupied by the third PUCCH is the same as the sequence resource occupied by the second PUCCH.

That is, when the high priority information is HARQ feedback information, the low priority information is SR information, and the formats of PUCCHs carrying the HARQ feedback information and the SR information are PUCCH format 1, the terminal device may transmit the SR information and the HARQ feedback information using time domain resources, frequency domain resources, and sequence resources of the second PUCCH.

Here, the transmission sequence of the third PUCCH is multiplied by the initial sequence based on the modulation symbol corresponding to the HARQ feedback information.

In another embodiment of the present application, if the number of time domain symbols included in the second PUCCH is smaller than the number of time domain symbols included in the first PUCCH, the third PUCCH is the first PUCCH.

Here, the third PUCCH is used to transmit the first information.

That is, when the number of time domain symbols included in the preconfigured second PUCCH carrying low priority information is smaller than the number of time domain symbols included in the preconfigured first PUCCH carrying high priority information, the low priority information is discarded, and the first information having the high priority is transmitted through the first PUCCH carrying the high priority information.

It can be appreciated that PUCCH format 0 and PUCCH format 1 each occupy 1 PRB in the frequency domain resource, and the transmission reliability thereof is mainly affected by the number of time domain symbols (1 or 2). The greater the number of time domain symbols, the longer the time to provide PUCCH transmission, contributing to an increase in coverage distance and thus higher reliability of transmission.

Based on this, when the number of time domain symbols included in the second PUCCH corresponding to the second information having the low priority is smaller than the number of time domain symbols included in the first PUCCH corresponding to the first information having the high priority, still forcing multiplexing transmission may affect transmission reliability of the high priority information. Therefore, when the number of time domain symbols included in the second PUCCH is smaller than the number of time domain symbols included in the first PUCCH, the second information of low priority may be directly discarded, and the first information of high priority may be transmitted only through the first PUCCH, thereby ensuring reliability of transmission of the high priority information.

The uplink control information transmission method provided by the embodiment of the present application is described below with reference to the flowchart shown in fig. 3.

Referring to fig. 3, the uplink control information transmission method provided by the embodiment of the present application may include the following steps:

step 310, determining that the time domain resource of the first PUCCH preconfigured to carry the first information overlaps with the time domain resource of the second PUCCH preconfigured to carry the second information.

Here, the second information has a lower priority than the first information.

In an embodiment of the present application, the first information is SR information, the second information is HARQ feedback information, and both the first PUCCH and the second PUCCH adopt PUCCH format 0.

In another embodiment of the present application, the first information is HARQ feedback information, the second information is SR information, and the first PUCCH and the second PUCCH both adopt PUCCH format 1.

Step 320, determine whether there is an uplink SR.

The terminal device may determine whether there is an uplink SR currently sent, i.e. determine whether the SR is positive or negative.

If the terminal device does not have an uplink SR transmission (i.e. SR is negative), step 330 is performed. If the terminal device has an uplink SR transmission (i.e. SR is positive), step 340 is performed.

Step 330, if the terminal device does not have uplink SR transmission, the terminal device sends HARQ feedback information through pre-configuring a PUCCH carrying HARQ feedback information.

It can be appreciated that in the case where the terminal device does not have an uplink SR transmission, the terminal device may directly transmit HARQ feedback information.

Specifically, in the first embodiment provided in step 310, after the terminal device determines that there is no uplink SR, HARQ feedback information may be transmitted through the second PUCCH. In the second embodiment provided in step 310, after the terminal device determines that there is no uplink SR, HARQ feedback information may be transmitted through the first PUCCH.

It should be noted that the branching step is performed in the same manner as the processing specified by R15.

In step 340, if the terminal device has uplink SR transmission, it is determined whether the number of time domain symbols included in the second PUCCH is smaller than the number of time domain symbols included in the first PUCCH.

Specifically, if the number of time domain symbols included in the second PUCCH is smaller than the number of time domain symbols included in the first PUCCH, step 350 is performed. If the number of time domain symbols included in the second PUCCH is not less than the number of time domain symbols included in the first PUCCH, step 360 is performed.

In step 350, if the number of time domain symbols included in the second PUCCH is smaller than the number of time domain symbols included in the first PUCCH, the first information is transmitted through the first PUCCH, and the second information is discarded.

It can be appreciated that when the number of time domain symbols included in the second PUCCH is smaller than the number of time domain symbols included in the first PUCCH, it may be determined that the transmission reliability of the second PUCCH carrying the low priority information (i.e. the second information) is low, and if the transmission is multiplexed, the transmission reliability of the high priority information (i.e. the first information) cannot be guaranteed. Accordingly, in case that the number of time domain symbols included in the second PUCCH is smaller than the number of time domain symbols included in the first PUCCH, the low priority information may be discarded, and the high priority information may be transmitted only through the first PUCCH.

It should be noted that the branching step is performed in the same manner as the processing specified by R16.

In step 360, the number of time domain symbols included in the second PUCCH is not less than the number of time domain symbols included in the first PUCCH, and the first information and the second information are multiplexed and transmitted through the transmission resource of the second PUCCH.

It can be appreciated that when the number of time domain symbols included in the second PUCCH is greater than or equal to the number of time domain symbols included in the first PUCCH, it can be determined that the transmission reliability of the second PUCCH carrying the low priority information (i.e. the second information) is higher, and the first information and the second information are multiplexed and transmitted through the transmission resource of the second PUCCH, so that the performance requirement of the high priority information can be ensured.

Specifically, in the first embodiment provided in step 310, when the terminal device determines that the number of time domain symbols included in the second PUCCH is greater than or equal to the number of time domain symbols included in the first PUCCH, the terminal device may transmit a third PUCCH in PUCCH format 0 using the same time domain resource and frequency domain resource as the second PUCCH, and the cyclic shift offset of the third PUCCH may be determined by the correspondence shown in table 4 or 5.

In the second embodiment provided in step 310, when the terminal device determines that the number of time domain symbols included in the second PUCCH is greater than or equal to the number of time domain symbols included in the first PUCCH, the terminal device may transmit a third PUCCH using time domain resources, frequency domain resources, and sequence resources of the second PUCCH, where the third PUCCH is capable of carrying the first information and the second information. The terminal device may multiply the sequence with a modulation symbol corresponding to the HARQ feedback information to obtain a third PUCCH.

In summary, the embodiment of the application can ensure the reliability of the high priority information during multiplexing transmission by using the time domain symbol as the judgment condition of multiplexing transmission. And the specific behavior of the terminal equipment is the same as the behavior defined by the existing R15 and R16, and no new processing complexity is introduced.

The embodiment of the application also provides an uplink control information transmission method, and referring to the flow chart shown in fig. 4, the uplink control information transmission method can be as follows

In step 410, when the terminal device has an uplink SR and the first PUCCH carrying SR information is preconfigured to overlap with the second PUCCHs carrying HARQ feedback information, the terminal device transmits the PUCCH carrying the first information from the first PUCCH and the second PUCCHs.

In step 420, the network device receives the first PUCCH or the plurality of second PUCCHs when the first PUCCH carrying SR information is preconfigured to overlap with the plurality of second PUCCHs preconfigured to carry HARQ feedback information.

Here, the priorities of the SR information and the HARQ feedback information are different; the first information is information with high priority of SR information and HARQ feedback information.

The priorities of the plurality of HARQ feedback information carried by the plurality of PUCCHs are the same, and the plurality of second PUCCHs do not overlap with each other.

In the embodiment of the present application, the situation that the terminal device does not expect that the time domain resource of one first PUCCH overlaps with the time domain resources of a plurality of second PUCCHs occurs. However, in practical applications, the time domain resources of the first PUCCH and the plurality of second PUCCHs inevitably overlap. Therefore, in the embodiment of the present application, when one first PUCCH overlaps with time domain resources of a plurality of second PUCCHs, the terminal device may preferentially transmit PUCCHs carrying first information with high priority, and discard PUCCHs carrying information with low priority. Thus, the transmission reliability of the high-priority information is ensured.

Correspondingly, after determining that the time domain resources of the first PUCCH overlap with the time domain resources of the plurality of second PUCCHs, the network device may monitor uplink control information on the first PUCCH and the plurality of second PUCCHs at the same time, because the network device cannot determine whether the terminal device currently has an uplink SR. That is, the network device may receive SR information carried by the first PUCCH or HARQ feedback information carried by the plurality of second PUCCHs.

In the embodiment of the present application, the PUCCH format of the first PUCCH is the same as the PUCCH formats of the plurality of second PUCCHs. Specifically, PUCCH formats of the first PUCCH and the second PUCCH are PUCCH format 0 or PUCCH format 1.

In an embodiment of the present application, if the SR information has a higher priority than the plurality of HARQ feedback information, the terminal device transmits the first PUCCH. Here, PUCCH formats of the first PUCCH and the plurality of second PUCCHs are PUCCH format 0.

It may be understood that in the case that the terminal device has an uplink SR, when the priority of the SR information is higher than the priority of the plurality of HARQ feedback information, the terminal device discards the plurality of second PUCCHs and the plurality of HARQ feedback information carried by the plurality of second PUCCHs, and transmits the SR information having a high priority only through the first PUCCH. In this way, the transmission reliability of the SR information carried in the first PUCCH is ensured.

Correspondingly, since the network device cannot determine whether the current terminal device has the uplink SR, after determining that the priority of the SR information is higher than that of the plurality of HARQ feedback information, the network device may monitor the first PUCCH and the plurality of second PUCCHs at the same time, receive the SR information through the first PUCCH, or receive the HARQ feedback information through the plurality of second PUCCHs.

In another embodiment of the present application, if the SR information has a lower priority than the HARQ feedback information, the terminal device transmits a plurality of second PUCCHs. Here, PUCCH formats of the first PUCCH and the plurality of second PUCCHs are PUCCH format 1.

It may be appreciated that, when the priorities of the plurality of HARQ feedback information are higher than the priorities of the SR information, the terminal device may discard the first PUCCH and the SR information carried by the first PUCCH, and transmit the HARQ feedback information having a high priority through the plurality of second PUCCHs. In this way, transmission reliability of the HARQ feedback information carried in the plurality of second PUCCHs is ensured.

Correspondingly, after the network device determines that the priority of the SR information is lower than the priority of the HARQ feedback information, the network device may determine that the terminal device discards the SR information with low priority, and only transmit the plurality of second PUCCHs carrying the HARQ feedback information with high priority. Therefore, the network device may only monitor the plurality of second PUCCHs and receive HARQ feedback information carried by the plurality of second PUCCHs.

In addition, in an embodiment of the present application, when the terminal device has an uplink SR and a first PUCCH that is preconfigured to carry SR information overlaps with a second PUCCH that is preconfigured to carry HARQ feedback information, the terminal may transmit the SR and the HARQ feedback information through a third PUCCH when the constraint condition is satisfied.

Correspondingly, the network device may receive the SR and HARQ feedback information through the third PUCCH when the first PUCCH that is preconfigured to carry the SR information overlaps with the second PUCCH that is preconfigured to carry the HARQ feedback information and the constraint condition is satisfied

The SR information and the HARQ feedback information have different priorities, and the constraint conditions include: the relationship between the number of time domain symbols included in the first PUCCH and the number of time domain symbols included in the second PUCCH satisfies a first preset condition.

It may be appreciated that after determining that one first PUCCH and one second PUCCH overlap on a time domain resource, the number of time domain symbols included in the first PUCCH carrying SR information and the number of time domain symbols included in the second PUCCH carrying HARQ feedback information may be determined whether the first preset condition is satisfied, and if the first preset condition is satisfied, the SR and HARQ feedback information may be transmitted through the third PUCCH.

Specifically, in an embodiment of the present application, when the priority of the SR information is higher than the priority of the HARQ feedback information, and the PUCCH formats of the first PUCCH and the second PUCCH are both PUCCH format 0, the first preset condition may be that the number of time domain symbols included in the second PUCCH is greater than or equal to the number of time domain symbols included in the first PUCCH.

That is, when the number of time domain symbols included in the second PUCCH carrying HARQ feedback information (i.e. low priority information) is greater than or equal to the number of time domain symbols included in the first PUCCH carrying SR information (i.e. high priority information), the SR and HARQ feedback information are multiplexed through the third PUCCH.

The time domain resource of the third PUCCH is the same as the time domain resource of the second PUCCH, and the frequency domain resource of the third PUCCH is the same as the frequency domain resource of the second PUCCH. That is, when the number of time domain symbols included in the second PUCCH is greater than or equal to the number of time domain symbols included in the first PUCCH, the SR and HARQ feedback information are multiplexed using time domain resources and frequency domain resources of the second PUCCH. Wherein, the cyclic shift offset of the transmission sequence of the third PUCCH may be determined according to table 4 or table 5.

It can be understood that in the embodiment of the present application, the second PUCCH carries HARQ feedback information with low priority, and the first PUCCH carries SR information with high priority. When the number of the time domain symbols included in the second PUCCH is greater than or equal to the number of the time domain symbols included in the first PUCCH, the SR and HARQ feedback information can be multiplexed and transmitted by using the time domain resource and the frequency domain resource of the second PUCCH, so that the transmission reliability of the SR information with high priority can be ensured, the HAQR feedback information with low priority can be multiplexed and transmitted, and the data transmission efficiency is effectively improved.

In another embodiment of the present application, when the priority of the SR information is lower than the priority of the HARQ feedback information, and the first PUCCH and the second PUCCH both adopt PUCCH format 1, the first preset condition may be that the number of time domain symbols included in the first PUCCH is greater than or equal to the number of time domain symbols included in the second PUCCH.

That is, when the number of time domain symbols included in the first PUCCH carrying SR feedback information (i.e., low priority information) is greater than or equal to the number of time domain symbols included in the second PUCCH carrying HARQ feedback information (i.e., high priority information), SR and HARQ feedback information are multiplexed through the third PUCCH.

Here, the time domain resource of the third PUCCH is identical to the time domain resource of the first PUCCH, the frequency domain resource of the third PUCCH is identical to the frequency domain resource of the first PUCCH, and the sequence resource of the third PUCCH is identical to the sequence resource of the first PUCCH.

It can be understood that in the embodiment of the present application, the first PUCCH carries SR information with low priority, and the second PUCCH carries HARQ feedback information with high priority. When the number of time domain symbols included in the first PUCCH is greater than or equal to that of time domain symbols included in the second PUCCH, the time domain resource, the frequency domain resource and the sequence resource of the first PUCCH are utilized to multiplex and transmit the SR and the HARQ feedback information, so that the transmission reliability of the high-priority HARQ information can be ensured, the low-priority SR information can be multiplexed and transmitted, and the data transmission efficiency is effectively improved.

The uplink control information transmission method provided by the embodiment of the application is explained in detail below in combination with a specific application scenario.

Example 1

Referring to a schematic diagram of a scenario of uplink control information multiplexing transmission shown in fig. 5, in this embodiment, a first PUCCH and a second PUCCH overlap in the time domain. The first PUCCH and the second PUCCH adopt PUCCH format 0 to transmit information, the first PUCCH carries SR information, and the second PUCCH carries HARQ feedback information. The SR information has a higher priority than the HARQ feedback information.

In one possible implementation, when the SR information is negative, the terminal device transmits HARQ feedback information through the second PUCCH. The processing manner of the terminal device in the implementation manner is the same as that of R15.

In another possible implementation, when the SR information is positive, the terminal device may determine a manner of multiplexing transmission based on a relationship between the number of time domain symbols of the first PUCCH and the number of time domain symbols of the second PUCCH.

Specifically, if the number of time domain symbols included in the second PUCCH is greater than or equal to the number of time domain symbols included in the first PUCCH, the SR information and the HARQ feedback information are multiplexed and transmitted. That is, the number of symbols included in the second PUCCH carrying low priority information is greater than or equal to the number of symbols included in the first PUCCH carrying high priority information, and the low priority information and the high priority information are multiplexed and transmitted.

Further, the multiplexing transmission of the SR information and the HARQ feedback information may be that a third PUCCH may be transmitted using the time domain resource and the frequency domain resource of the second PUCCH, where the SR information and the HARQ feedback information may be carried, and the format of the third PUCCH is still PUCCH format 0.

Here, the third PUCCH carries SR information and HARQ feedback information, which may specifically be that the terminal device selects the target cyclic shift offset according to the specific content of the HARQ feedback information; further, a transmission sequence corresponding to the third PUCCH is obtained from the target cyclic offset and the base sequence. Specifically, the terminal device may determine the target cyclic shift offset corresponding to the HARQ feedback information according to the corresponding relationship between the HARQ feedback information and the cyclic shift offset in the multiplexing scenario shown in table 4 or table 5.

It can be appreciated that PUCCH format 0 occupies 1 PRB fixedly on the frequency domain resource, and its transmission reliability is mainly affected by the number of time domain symbols (1 or 2). The longer the number of time domain symbols, the longer the PUCCH transmission is provided, contributing to an increase in coverage distance, and thus the higher the reliability of the transmission. When the number of time domain symbols included in the second PUCCH corresponding to the low priority HARQ feedback information is greater than or equal to the number of time domain symbols included in the first PUCCH format corresponding to the high priority SR information, the same time-frequency resource as the second PUCCH carrying the low priority HARQ feedback information is used, but when the SR information and the HARQ feedback information are transmitted through the third PUCCH with a different cyclic offset, the transmission reliability of the SR information can still be ensured.

It is noted that the terminal device in this implementation is handled in the same manner as R15.

In addition, if the number of time domain symbols included in the second PUCCH is greater than or equal to the number of time domain symbols included in the first PUCCH, the terminal device transmits SR information through the first PUCCH and discards HARQ feedback information.

That is, if the number of time domain symbols included in the second PUCCH carrying low priority information is smaller than the number of time domain symbols included in the first PUCCH carrying high priority information, the low priority information is discarded and only the high priority information is transmitted. Thus, the reliability of the high-priority information is ensured.

It is noted that the terminal device in this implementation is handled in the same way as R16.

Therefore, the embodiment of the application introduces the judgment condition of the time domain symbol, and ensures the reliability of the UCI with high priority in multiplexing transmission. In addition, the specific behavior of the terminal equipment in the embodiment of the application is the same as that of the existing R15 and R16, and no new processing complexity is introduced.

In this embodiment, the above example only describes a manner when one first PUCCH overlaps one second PUCCH time domain resource. The terminal device does not expect that the time domain resources of one first PUCCH overlap with the time domain resources of the plurality of second PUCCHs, wherein the time domain resources do not overlap with each other.

Here, the HARQ feedback information of low priority is insensitive to transmission delay, and the network device can avoid the situation that the first PUCCH overlaps with the plurality of second PUCCH time domain resources by reasonable scheduling. If scheduling avoidance is not performed, the processing can be performed in the following manner.

Specifically, referring to fig. 6, if the time domain resource of one first PUCCH (e.g. PUCCH a shown in fig. 6) overlaps with the time domain resource of the plurality of second PUCCHs, and the time domain resources of the plurality of second PUCCHs (e.g. PUCCH X and PUCCH Y shown in fig. 6) do not overlap with each other, the terminal device may transmit SR information of high priority through the first PUCCH (i.e. PUCCH a shown in fig. 6), and discard all HARQ feedback information of low priority carried in the plurality of second PUCCHs (i.e. PUCCH X and PUCCH Y shown in fig. 6).

It is noted that the processing manner of the terminal device in this implementation is the same as the processing mechanism specified in R16.

Example two

Referring to a schematic diagram of a scenario of uplink control information multiplexing transmission shown in fig. 7, in this embodiment, a first PUCCH and a second PUCCH overlap in the time domain. The first PUCCH and the second PUCCH adopt PUCCH format 1 to transmit information, the first PUCCH is used for bearing HARQ feedback information, the second PUCCH is used for bearing SR information, and the priority of the HARQ feedback information is higher than that of the SR information.

In one possible implementation, when the SR information is negative, the terminal device transmits HARQ feedback information through the first PUCCH. The processing manner of the terminal device in the implementation manner is the same as that of R15.

In another possible implementation, when the SR information is positive, the terminal device may determine a manner of multiplexing transmission based on a relationship between the number of time domain symbols included in the first PUCCH and the number of time domain symbols included in the second PUCCH.

Specifically, if the number of time domain symbols included in the second PUCCH is greater than or equal to the number of time domain symbols included in the first PUCCH, the SR information and the HARQ feedback information are multiplexed and transmitted. That is, the number of time domain symbols included in the second PUCCH carrying low priority information is greater than or equal to the number of time domain symbols included in the first PUCCH carrying high priority information, and the low priority information and the high priority information are multiplexed and transmitted.

Further, the SR information and the HARQ feedback information may be multiplexed and transmitted, and the SR information and the HARQ feedback information may be carried in a third PUCCH transmitted using time domain resources, frequency domain resources, and sequence resources of the second PUCCH. Wherein the format of the third PUCCH is still PUCCH format 1.

Here, the SR information and the HARQ feedback information are carried in the third PUCCH, and specifically, the terminal device may multiply a modulation symbol corresponding to the HARQ feedback information onto the cyclic shift sequence for transmission.

It can be appreciated that PUCCH format 1 occupies 1 PRB fixedly on the frequency domain resource, and its transmission reliability is mainly affected by the number of time domain symbols (1 or 2). The longer the number of time domain symbols, the longer the PUCCH transmission is provided, contributing to an increase in coverage distance, and thus the higher the reliability of the transmission. When the number of time domain symbols included in the second PUCCH corresponding to the low-priority SR feedback information is greater than or equal to the number of time domain symbols included in the first PUCCH format corresponding to the high-priority HARQ feedback information, the high-priority HARQ feedback information is transmitted using the second PUCCH preconfigured to transmit the low-priority SR information, and transmission reliability of the HARQ feedback information can still be ensured.

In addition, if the number of time domain symbols included in the second PUCCH is greater than or equal to the number of time domain symbols included in the first PUCCH, the terminal device transmits HARQ feedback information of high priority through the first PUCCH, and discards SR information of low priority.

Specifically, referring to fig. 8, if the time domain resource of one second PUCCH (e.g. PUCCH a 'shown in fig. 8) overlaps with the time domain resource of the plurality of first PUCCHs and the time domain resource of the plurality of second PUCCHs (e.g. PUCCH X' and PUCCH Y 'shown in fig. 8) do not overlap with each other, the terminal device may transmit HARQ feedback information of high priority through the plurality of second PUCCHs (i.e. PUCCH X' and PUCCH Y 'shown in fig. 8) and discard SR information of low priority carried in the first PUCCH (i.e. PUCCH a' shown in fig. 8).

In summary, the embodiment of the application can introduce the judgment condition of the time domain symbol, ensure the reliability of the high priority information during multiplexing transmission, and improve the data transmission efficiency. And the specific behavior of the terminal equipment is the same as that of the existing R15 and R16, and no new processing complexity is introduced.
