Detailed ways

In order to make the purpose, technical solution and advantages of the present application clearer, the implementation of the present application will be further described in detail below in conjunction with the accompanying drawings. The attached drawings are only for reference and description, and are not intended to limit the embodiments of the present invention.

It should be noted that the terms "first" and "second" in the specification and claims of the present application and the above drawings are used to distinguish different objects, rather than to describe a specific order. Furthermore, the terms "include" and "have", as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but optionally also includes unlisted steps or units, or optionally further includes For other steps or units inherent in these processes, methods, products or devices.

Before further describing the embodiments of the present invention in detail, the nouns and terms involved in the embodiments of the present invention are described, and the nouns and terms involved in the embodiments of the present invention are applicable to the following explanations.

1) PUCCH format.

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

The UCI carried on the PUCCH has multiple formats. Referring to Table 1, both PUCCH format 0 and PUCCH format 1 can carry 1-bit or 2-bit UCI information. The difference is that PUCCH format 0 can occupy up to 2 time-domain symbols, while PUCCH format 1 can occupy 4-14 time-domain symbols.

Table 1

PUCCH format number of symbols in the time domain Number of UCI bits carried Number of Physical Resource Blocks 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 practical applications, PUCCH format 0 and PUCCH format 1 use cyclic shift sequences in the frequency domain. Wherein, the UCI carried in PUCCH format 0 is implicitly indicated by the selected cyclic shift offset (m _cs ).

Specifically, when the terminal device uses PUCCH format 0 to transmit the HARQ feedback information, it can determine the initial sequence used for transmission according to the instruction information of the network device. At the same time, the terminal device can determine the cyclic shift offset (m _cs ) according to the specific content of the HARQ feedback information. In this way, the terminal device can superimpose the above m _cs on the basis of the determined initial sequence to obtain the final transmission sequence. Correspondingly, the network device can determine the m _cs used by the terminal device according to the received transmission sequence. Further, the network device may determine the specific content of the HARQ feedback information corresponding to m _cs according to the correspondence between the HARQ feedback information and the cyclic shift offset.

Here, the corresponding relationship between the HARQ feedback information and the cyclic shift offset may refer to Table 2 and Table 3. Wherein, Table 2 shows the correspondence between the HARQ feedback information and the cyclic shift offset when the 1-bit HARQ feedback information is transmitted through the PUCCH format 0. Table 3 shows the correspondence between the HARQ feedback information and the cyclic shift offset when the 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

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

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

When the terminal equipment uses PUCCH format 1 to transmit the HARQ feedback information, it can multiply the modulation symbol d(0) corresponding to the 1-bit or 2-bit HARQ feedback information to the cyclic shift sequence for transmission.

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

2) Uplink control information multiplexing

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

Rule 1: When both PUCCH1 carrying SR information and PUCCH2 carrying HARQ feedback information adopt PUCCH format 0:

If the SR information is negative, the terminal device transmits HARQ feedback information through PUCCH2;

If the SR information is positive, the terminal device transmits a PUCCH3 in the physical resource block (Physical Resource Block, PRB) where the PUCCH2 is located. Wherein, the cyclic shift offset (m _cs ) used by PUCCH3 can be determined 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.

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

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

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

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

Rule 3: When both PUCCH1 carrying SR information and PUCCH2 carrying HARQ feedback information adopt PUCCH format 1:

If SR is positive, the terminal device transmits HARQ feedback information through PUCCH1.

If SR is negative, the terminal device transmits HARQ feedback information through PUCCH2.

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

The R16 of the NR system introduces the UCI priority policy, and the terminal device will give priority to the transmission of high-priority UCI. However, discarding low-priority UCIs will adversely affect uplink services. For this reason, in the discussion of the R17 version, it is supported to multiplex and transmit UCIs with different priorities overlapping time domain resources. However, there is no definite method how to multiplex and transmit UCIs with different priorities.

Based on this, an embodiment of the present application provides a method for transmitting uplink control information. Specifically, the terminal device determines the time-domain resources of the first PUCCH carrying high-priority information (that is, the first information), and carries low-priority information. (that is, the second information) after the time-domain resources of the second PUCCH overlap, the terminal device or the network device may base on 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 , to determine a third PUCCH, and send or receive at least one of the first information and the second information through the third PUCCH. That is to say, when the uplink control information of different priorities overlaps in the time domain, an appropriate third PUCCH can be selected to multiplex and transmit the uplink control information of different priorities to improve 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 in conjunction with the drawings in the embodiments of the present application.

An embodiment of the present application provides a method for transmitting uplink control information, which can be applied to the communication system architecture shown in FIG. 1 . Specifically, referring to the schematic flow chart shown in FIG. 2, the transmission of uplink control information provided in this embodiment of the present application may include the following steps:

Step 210: In the case of having an 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 send 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 this embodiment of the present application, the third PUCCH is determined based on 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; wherein, one of the first information and the second information The information is SR information, and the first PUCCH overlaps with the second PUCCH; the first PUCCH is a PUCCH pre-configured to carry the first information, and the second PUCCH is a PUCCH pre-configured to carry the second information; the priority of the second information is lower than that of the first PUCCH. Information priority.

Here, the overlapping of the first PUCCH and the second PUCCH specifically means that time domain resources of the first PUCCH overlap with time domain resources of the second PUCCH. Here, the overlap of time domain resources may mean that the time domain resources of the first PUCCH partially overlap with the time domain resources of the second PUCCH, or it may mean that the time domain resources of the first PUCCH and the time domain resources of the second PUCCH completely overlap. Applications are not limited to this.

In the embodiment of the present application, the network device may 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 here may be high-layer signaling or physical layer signaling, and the high-layer signaling may be radio resource control (Radio Resource Control, RRC) signaling or medium access control (Medium Access Control, MAC) control element (Control Element, CE), and the physical layer signaling may be downlink control information (Downlink Control Information, DCI). This embodiment of the present application does not limit it.

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

In this embodiment of the application, the priority can be understood as the transmission priority of the information. The higher the priority of the information, the higher the performance requirements for the transmission of the information. The performance requirement here specifically refers to the requirement on transmission reliability or the requirement on time delay, which is not limited in this embodiment of the present application.

Specifically, the network device may assign different priorities to each UCI based on requirements on information transmission performance. Exemplarily, if the first information is sensitive to delay, the network device may assign high priority to the first information, and if the second information is not sensitive to delay, may assign low priority to the second information.

In this 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 terminal device does not expect that the time domain resources of a first PUCCH overlap with the time domain resources of multiple second PUCCHs, where the time domain resources between the multiple second PUCCHs are different from each other. overlapping. The number of the first PUCCH and the number of the second PUCCH in the embodiment of the present application is one. That is to say, the time domain resource of the first PUCCH mentioned in the embodiment of the present application overlaps with the time domain resource of the second PUCCH, specifically, the time domain resource of a first PUCCH overlaps with the time domain resource of a second PUCCH .

It can be understood that, after determining that the time domain resources of the first PUCCH carrying high priority information (that is, the first information) overlap with the time domain resources of the second PUCCH carrying low priority information (that is, the second information) , the terminal device or network device can determine the third PUCCH according to the relationship between the number of time domain symbols contained in the first PUCCH and the number of time domain symbols contained in the second PUCCH, and send or receive the first information and At least one piece of information in the second information. That is to say, when the uplink control information of different priorities overlaps in the time domain, an appropriate third PUCCH can be selected to multiplex and transmit the uplink control information of different priorities to improve data transmission efficiency.

In practical applications, the terminal device does not always have an uplink SR, that is, the terminal device does not always have the need to send SR information. When the terminal device has an uplink SR, it is considered that the SR is positive (ie positive). When the terminal device does not have an uplink SR, the SR is considered negative (that is, negative).

In the embodiment of the present application, when there is an uplink SR, that is, the SR is positive, the terminal device may, according to 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, to determine the third 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 only transmit other information.

Exemplarily, the first PUCCH is pre-configured to carry SR information, and the second PUCCH is pre-configured to carry HARQ feedback information; regardless of whether the priority of SR information is higher than that of HARQ feedback information or lower than that of HARQ feedback information, the terminal device passes the second The PUCCH transmits HARQ feedback information.

Correspondingly, after determining that the first PUCCH and the second PUCCH overlap in the time domain, the network device may determine the 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 , receiving the first message and/or the second message on the third PUCCH.

In the embodiment of the present application, after it is determined that PUCCH time domain resources of different priority information overlap, 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 can be A third PUCCH is determined, and at least one of the first information and the second information is further transmitted through the third PUCCH.

Wherein, the time domain symbol may be an Orthogonal Frequency Division Multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbol, or may be a Single Carrier Frequency Division Multiplexing (Single Carrier Frequency Division Multiplexing, SC-FDM) symbol. This embodiment of the present application does not limit it.

The following describes how to determine the third PUCCH based on 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.

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 to say, 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 The device may use the same transmission resource as that of the second PUCCH to multiplex and transmit the first information and the second information. That is, the same transmission resources of the second PUCCH are used to transmit the first information and the second information.

It should be noted that the PUCCH format of the first PUCCH in the embodiment of the present application is the same as the PUCCH format of the second PUCCH. Specifically, the PUCCH formats of the first PUCCH and the second PUCCH are both PUCCH format 0 or PUCCH format 1.

It can be understood that both PUCCH format 0 and PUCCH format 1 occupy one PRB in the frequency domain resource, and their transmission reliability is mainly affected by the number of symbols in the time domain (1 or 2). The larger the number of symbols in the time domain, the longer the time for PUCCH transmission, which helps to improve the coverage distance and thus the higher the transmission reliability. 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, use the same The same time-frequency resource of the second PUCCH carrying the low-priority information transmits the first information and the second information at the same time, which can ensure the transmission reliability of the high-priority information.

In the embodiment of the present application, the transmission resources of the third PUCCH and the transmission resources of the second PUCCH may be the same and may include multiple manners, two of which are described in detail below.

In the first possible implementation manner, the transmission resources of the third PUCCH are the same as the transmission resources of the second PUCCH, which may mean that the time domain resources occupied by the third PUCCH are the same as the time domain resources occupied by the second PUCCH, and the third PUCCH The frequency domain resources occupied by the PUCCH are the same as the frequency domain resources 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 both PUCCH format 0, the time domain resource occupied by the third PUCCH is the same as that of the second PUCCH. The time domain resources occupied by the PUCCH are the same, and the frequency domain resources occupied by the third PUCCH are the same as the frequency domain resources occupied by the second PUCCH.

That is to say, when the high-priority information is SR information, the low-priority information is HARQ feedback information, and the format of the PUCCH carrying SR information and HARQ feedback information is both PUCCH format 0, when the terminal device can use the second PUCCH domain resources and frequency domain resources, and multiplex and transmit SR information and HARQ feedback information.

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 the cyclic shift offset corresponding to the specific content of the HARQ feedback information from Table 4 or Table 5, and determine the third PUCCH transmission sequence.

In the second possible implementation manner, the transmission resources of the third PUCCH are the same as the transmission resources of the second PUCCH, which may mean that the time domain resources occupied by the third PUCCH are the same as the time domain resources occupied by the second PUCCH, and the third PUCCH The frequency domain resources occupied by the second PUCCH are the same as the frequency domain resources occupied by the second PUCCH, and the sequence resources occupied by the third PUCCH are the same as the sequence resources 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 both PUCCH format 1, the time domain resource occupied by the third PUCCH is different from that of the second PUCCH. The time domain resources occupied by the PUCCH are the same, the frequency domain resources occupied by the third PUCCH are the same as the frequency domain resources occupied by the second PUCCH, and the sequence resources occupied by the third PUCCH are the same as the sequence resources occupied by the second PUCCH.

That is to say, when the high-priority information is HARQ feedback information, the low-priority information is SR information, and the format of the PUCCH carrying the HARQ feedback information and SR information is both PUCCH format 1, when the terminal device can use the second PUCCH domain resources, frequency domain resources and sequence resources, and transmit SR information and HARQ feedback information.

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

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

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

That is to say, when the number of time-domain symbols included in the pre-configured second PUCCH carrying low-priority information is less than the number of time-domain symbols included in the pre-configured first PUCCH carrying high-priority information, the low-priority The first information with high priority is transmitted through the first PUCCH carrying the high priority information.

It should be noted that the PUCCH format of the first PUCCH in the embodiment of the present application is the same as the PUCCH format of the second PUCCH. Specifically, the PUCCH formats of the first PUCCH and the second PUCCH are both PUCCH format 0 or PUCCH format 1.

It can be understood that both PUCCH format 0 and PUCCH format 1 occupy one PRB in the frequency domain resource, and their transmission reliability is mainly affected by the number of symbols in the time domain (1 or 2). The larger the number of symbols in the time domain, the longer the PUCCH transmission time is provided, which helps to improve the coverage distance, so that the reliability of the transmission is higher.

Based on this, when the number of time-domain symbols included in the second PUCCH corresponding to the second information with low priority is smaller than the number of time-domain symbols included in the first PUCCH corresponding to the first information with high priority, still forcibly Multiplexing transmissions may affect the transmission reliability of high-priority information. Therefore, when the number of time domain symbols included in the second PUCCH is less than the number of time domain symbols included in the first PUCCH, the second information of low priority can be directly discarded, and only the first PUCCH is used to transmit the first information of high priority. One message, so as to ensure the reliability of high-priority message transmission.

The method for transmitting uplink control information provided by the embodiment of the present application will be described below with reference to the schematic flowchart shown in FIG. 3 .

Referring to Figure 3, the method for transmitting uplink control information provided in the embodiment of the present application may include the following steps:

Step 310: Determine that the time domain resources preconfigured for the first PUCCH carrying the first information overlap with the time domain resources preconfigured for the second PUCCH carrying 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 use PUCCH format 0.

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

Step 320, judging whether there is an uplink SR.

The terminal device can judge whether there is currently an uplink SR sent, that is, judge whether the SR is positive or negative.

If the terminal device has no uplink SR to send (that is, the SR is negative), step 330 is performed. If the terminal device has an uplink SR to send (that is, the SR is positive), step 340 is performed.

Step 330: If the terminal device has no uplink SR to send, the terminal device sends the HARQ feedback information by pre-configuring the PUCCH carrying the HARQ feedback information.

It can be understood that, in the case that the terminal device has no uplink SR to send, the terminal device may directly send HARQ feedback information.

Specifically, in the first embodiment provided in step 310, after the terminal device determines that it does not have an uplink SR, it may send HARQ feedback information through the second PUCCH. In the second embodiment provided in step 310, when the terminal device determines that it does not have an uplink SR, it may send HARQ feedback information through the first PUCCH.

It is worth noting that this branching step is executed in the same manner as it was handled in R15.

Step 340: If the terminal device has an uplink SR to send, determine 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.

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, transmit the first information through the first PUCCH, and discard the second information.

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

It is worth noting that this branching step is executed in the same manner as it is handled in R16.

Step 360 , 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, the first information and the second information are multiplexed and transmitted through the transmission resources of the second PUCCH.

It can be understood 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, the transmission reliability of the second PUCCH carrying low-priority information (ie, second information) can be determined Higher, multiplex transmission of the first information and the second information by using the transmission resource of the second PUCCH can ensure the performance requirement of the high priority information.

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 can use the same The same time domain resources and frequency domain resources of the two PUCCHs transmit a third PUCCH using PUCCH format 0, and the cyclic shift offset of the third PUCCH can be determined according to the corresponding relationship 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 can use the time domain symbols of the second PUCCH The domain resource, the frequency domain resource, and the sequence resource transmit the third PUCCH, and the third PUCCH can carry the first information and the second information. Wherein, the terminal device may obtain the third PUCCH by multiplying the modulation symbol corresponding to the HARQ feedback information by the sequence.

It is worth noting that this branching step is executed in the same manner as it was handled in R15.

To sum up, in the embodiment of the present application, time-domain symbols can be used as a decision condition for multiplexed transmission to ensure the reliability of high-priority information during multiplexed transmission. Moreover, the specific behavior of the terminal device is the same as the behavior defined in the existing R15 and R16, and no new processing complexity is introduced.

The embodiment of the present application also provides a method for transmitting uplink control information. Referring to the schematic flowchart shown in FIG. 4 , the method for transmitting uplink control information may be

Step 410: When the terminal device has an uplink SR, and the first PUCCH pre-configured to carry SR information overlaps with multiple second PUCCHs pre-configured to carry HARQ feedback information, the terminal device transmits the first PUCCH and multiple second PUCCHs. The PUCCH carrying the first information among the PUCCHs.

Step 420, the network device receives the first PUCCH or multiple second PUCCHs when the first PUCCH pre-configured to carry SR information overlaps with multiple second PUCCHs pre-configured to carry HARQ feedback information.

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

In addition, it should be noted that the multiple second PUCCHs do not overlap each other, and the multiple HARQ feedback information carried by the multiple PUCCHs have the same priority.

In the embodiment of the present application, the terminal device does not expect that the time domain resources of one first PUCCH overlap with the time domain resources of multiple second PUCCHs. However, in practical applications, it is inevitable that time domain resources of the first PUCCH and multiple second PUCCHs overlap. Therefore, in the embodiment of the present application, when the time domain resources of one first PUCCH and multiple second PUCCHs overlap, the terminal device can preferentially send the PUCCH carrying the first information with high priority, and discard the information carrying low priority The PUCCH. In this way, transmission reliability of high-priority information is guaranteed.

Correspondingly, after the network device determines that the time domain resources of the first PUCCH and the multiple second PUCCHs overlap, because the network device cannot determine whether the terminal device currently has an uplink SR, the network device may use the first PUCCH and the multiple second PUCCH The uplink control information is monitored simultaneously on the two PUCCHs. That is to say, the network device may receive SR information carried by the first PUCCH, or HARQ feedback information carried by multiple second PUCCHs.

In this embodiment of the present application, the PUCCH format of the first PUCCH is the same as the PUCCH formats of multiple second PUCCHs. Specifically, the 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 priority of the SR information is higher than the priority of multiple pieces of HARQ feedback information, the terminal device transmits the first PUCCH. Here, the PUCCH formats of the first PUCCH and the plurality of second PUCCHs are both PUCCH format 0.

It can be understood that, when the terminal device has an uplink SR, when the priority of the SR information is higher than the priority of multiple HARQ feedback information, the terminal device discards multiple second PUCCHs, and the multiple second PUCCHs carry For multiple HARQ feedback information, only the SR information with high priority is sent 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 an upper SR, after the network device determines that the priority of the SR information is higher than the priority of multiple HARQ feedback information, the network device can simultaneously monitor the first PUCCH and multiple HARQ feedback information. A second PUCCH, the SR information is received through the first PUCCH, or multiple second PUCCHs are used to receive HARQ feedback information.

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

It can be understood that when the priority of multiple HARQ feedback information is higher than the priority of SR information, the terminal device can discard the first PUCCH and the SR information carried by the first PUCCH, and transmit the information with high priority through multiple second PUCCHs. HARQ feedback information. In this way, the transmission reliability of the HARQ feedback information carried in multiple second PUCCHs is ensured.

Correspondingly, after the network device determines that the priority of the SR information is lower than that of the HARQ feedback information, the network device may determine that the terminal device will discard the low-priority SR information, and only send multiple messages carrying high-priority HARQ feedback information. a second PUCCH. Therefore, the network device can only monitor the multiple second PUCCHs, and receive the HARQ feedback information carried by the multiple second PUCCHs.

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

Correspondingly, the network device may receive SR and HARQ feedback through the third PUCCH when the first PUCCH pre-configured to carry SR information overlaps with a second PUCCH pre-configured to carry HARQ feedback information, and when the constraints are satisfied information

Wherein, the priorities of the SR information and the HARQ feedback information are different, and the constraints 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 the first preset condition.

It can be understood that after it is determined that a first PUCCH and a second PUCCH overlap on time domain resources, it can be determined that the number of time domain symbols included in the first PUCCH carrying SR information is different from that of the second PUCCH carrying HARQ feedback information. Whether the number of time-domain symbols included in the PUCCH satisfies the first preset condition, and if the first preset condition is met, transmit SR and HARQ feedback information through the third PUCCH.

Specifically, in an embodiment of the present application, when the priority of the SR information is higher than that of the HARQ feedback information, and the PUCCH formats of the first PUCCH and the second PUCCH are both PUCCH format 0, the above-mentioned first predetermined A condition may be assumed 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 to say, 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 time domain symbols included in the first PUCCH carrying SR information (i.e. high priority information) When the number of SR and HARQ feedback information is multiplexed and transmitted through the third PUCCH.

Here, the time domain resources of the third PUCCH are the same as the time domain resources of the second PUCCH, and the frequency domain resources of the third PUCCH are the same as the frequency domain resources of the second PUCCH. That is to say, 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, use the time-domain resources and frequency-domain resources of the second PUCCH to multiplex transmit SR and HARQ feedback information. 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 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 time-domain resources and frequency-domain resources of the second PUCCH can be used to multiplex and transmit SR and HARQ feedback information, not only The transmission reliability of high-priority SR information can be guaranteed, and low-priority HAQR feedback information can also be multiplexed and transmitted, effectively improving data transmission efficiency.

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

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

Here, the time domain resources of the third PUCCH are the same as the time domain resources of the first PUCCH, the frequency domain resources of the third PUCCH are the same as the frequency domain resources of the first PUCCH, and the sequence resources of the third PUCCH are the same as the sequence resources of the first PUCCH. same.

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 the number of time-domain symbols included in the second PUCCH, the time-domain resources, frequency-domain resources, and sequence resources of the first PUCCH are used to multiplex and transmit SR and HARQ feedback information, not only The transmission reliability of high-priority HARQ information can be guaranteed, and low-priority SR information can also be multiplexed and transmitted, thereby effectively improving data transmission efficiency.

The method for transmitting uplink control information provided by the embodiment of the present application will be described in detail below in combination with specific application scenarios.

Embodiment one

Referring to FIG. 5 , which is a first schematic diagram of a scenario of multiplexed transmission of uplink control information, in this embodiment, the first PUCCH and the second PUCCH overlap in the time domain. Wherein, both the first PUCCH and the second PUCCH use PUCCH format 0 to transmit information, and the first PUCCH carries SR information, and the second PUCCH carries HARQ feedback information. The priority of SR information is higher than that of HARQ feedback information.

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

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

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 to say, if 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, the low-priority information and high-priority information are multiplexed and transmitted .

Further, the multiplexing transmission of SR information and HARQ feedback information may be to use the time domain resources and frequency domain resources of the second PUCCH to transmit the third PUCCH, the third PUCCH may carry SR information and HARQ feedback information, and the third PUCCH The format is still PUCCH format 0.

Here, the SR information and HARQ feedback information are carried in the third PUCCH. Specifically, the terminal device may select the target cyclic shift offset according to the specific content of the HARQ feedback information; furthermore, according to the target cyclic offset and the base sequence, obtain The transmission sequence corresponding to the third PUCCH. Specifically, the terminal device may determine the target cyclic shift offset corresponding to the HARQ feedback information according to the correspondence between the HARQ feedback information and the cyclic shift offset in the multiplexing scenario shown in Table 4 or Table 5.

It can be understood that the PUCCH format 0 fixedly occupies 1 PRB in the frequency domain resource, and its transmission reliability is mainly affected by the number of symbols in the time domain (1 or 2). The larger the number of symbols in the time domain, the longer the PUCCH transmission time is provided, which helps to improve the coverage distance, so that the transmission reliability is higher. 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, use the low-priority HARQ feedback When the second PUCCH of the information has the same time-frequency resource but the third PUCCH with different cycle offsets transmits the SR information and the HARQ feedback information, the transmission reliability of the SR information can still be guaranteed.

It is worth noting that the processing method of the terminal device in this implementation is the same as that of 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 the HARQ feedback information.

That is to say, 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. priority information. In this way, the reliability of high-priority information is guaranteed.

It is worth noting that the processing method of the terminal device in this implementation is the same as that of R16.

It can be seen that the embodiment of the present application introduces the judgment condition of the time-domain symbol to ensure the reliability of the high-priority UCI during multiplexed transmission. In addition, the specific behavior of the terminal device in the embodiment of the present 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 illustrates the manner in which time domain resources of one first PUCCH and one second PUCCH overlap. The terminal device does not expect the time domain resources of one first PUCCH to overlap with the time domain resources of multiple second PUCCHs, where the time domain resources of the multiple second PUCCHs do not overlap with each other.

Here, the low-priority HARQ feedback information is not sensitive to transmission delay, and the network device can avoid the situation that the time domain resources of the first PUCCH and multiple second PUCCHs overlap through reasonable scheduling. If scheduling avoidance is not performed, it can be handled in the following ways.

Specifically, as shown in FIG. 6, if the time domain resources of a first PUCCH (such as PUCCH A shown in FIG. 6) overlap with the time domain resources of multiple second PUCCHs, and multiple second PUCCHs (such as When the time domain resources shown in PUCCH X and PUCCH Y) do not overlap with each other, the terminal device can transmit high-priority SR information through the first PUCCH (that is, PUCCH A shown in FIG. 6 ), and discard multiple second All low-priority HARQ feedback information carried in PUCCH (that is, PUCCH X and PUCCH Y shown in FIG. 6 ).

It is worth noting that the processing method of the terminal device in this implementation is the same as the processing mechanism specified in R16.

Embodiment two

Referring to FIG. 7 , which is a first schematic diagram of a scenario of multiplexed transmission of uplink control information, in this embodiment, the first PUCCH and the second PUCCH overlap in the time domain. Wherein, both the first PUCCH and the second PUCCH use PUCCH format 1 to transmit information, and the first PUCCH is used to carry HARQ feedback information, and the second PUCCH is used to carry SR information, and the priority of HARQ feedback information is higher than that of SR information. .

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

In another possible implementation, when the SR information is positive, the terminal device may determine the multiplexing based on 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. The method of transmission.

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 to say, if 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, then the low-priority information and the high-priority Level information is multiplexed and transmitted.

Further, the multiplexing transmission of SR information and HARQ feedback information may be to use the time domain resources, frequency domain resources and sequence resources of the second PUCCH to transmit the third PUCCH, and the third PUCCH carries the SR information and HARQ feedback information. 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. Specifically, the terminal device may multiply the modulation symbol corresponding to the HARQ feedback information to the cyclic shift sequence for transmission.

It can be understood that the PUCCH format 1 fixedly occupies one PRB in frequency domain resources, and its transmission reliability is mainly affected by the number of time domain symbols (1 or 2). The larger the number of symbols in the time domain, the longer the PUCCH transmission time is provided, which helps to improve the coverage distance, so that the transmission reliability is higher. 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, use pre-configuration for transmission The second PUCCH of the low-priority SR information transmits the high-priority HARQ feedback information, which can still ensure the transmission reliability of the HARQ feedback information.

It is worth noting that the processing method of the terminal device in this implementation is the same as that of 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 high-priority HARQ feedback information through the first PUCCH, and discards low-priority HARQ feedback information. SR information.

That is to say, 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. priority information. In this way, the reliability of high-priority information is guaranteed.

It is worth noting that the processing method of the terminal device in this implementation is the same as that of R16.

It can be seen that the embodiment of the present application introduces the judgment condition of the time-domain symbol to ensure the reliability of the high-priority UCI during multiplexed transmission. In addition, the specific behavior of the terminal device in the embodiment of the present 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 illustrates the manner in which time domain resources of one first PUCCH and one second PUCCH overlap. The terminal device does not expect the time domain resources of one first PUCCH to overlap with the time domain resources of multiple second PUCCHs, where the time domain resources of the multiple second PUCCHs do not overlap with each other.

Here, the low-priority HARQ feedback information is not sensitive to transmission delay, and the network device can avoid the situation that the time domain resources of the first PUCCH and multiple second PUCCHs overlap through reasonable scheduling. If scheduling avoidance is not performed, it can be handled in the following ways.

Specifically, referring to FIG. 8, if the time domain resources of one second PUCCH (such as PUCCH A' shown in FIG. 8) overlap with the time domain resources of multiple first PUCCHs, and multiple second PUCCHs (such as When the time domain resources between PUCCH X' and PUCCH Y' shown in Figure 8 do not overlap each other, the terminal device can transmit high-priority HARQ feedback information, and discard low-priority SR information carried in the first PUCCH (that is, PUCCH A' shown in FIG. 8 ).

To sum up, the embodiment of the present application can introduce the judgment condition of time-domain symbols to ensure the reliability of high-priority information during multiplexed transmission, and can also improve the efficiency of data transmission. Moreover, the specific behavior of the terminal device is the same as that of the existing R15 and R16, and no new processing complexity is introduced.
