That is, when the value of the second indication information in the fifth downlink control information is the first preset value, it is instructed to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information. When the value of the second indication information in the fifth downlink control information is not the first preset value, it indicates that the N pieces of first uplink information and the M pieces of second uplink information cannot be multiplexed and transmitted.

Optionally, the network device may indicate whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information through all values of the Z pieces of second indication information. That is, when the values of the Z pieces of second indication information respectively included in the Z pieces of second downlink control information are all the first preset values, it indicates that the N pieces of first uplink information and the M pieces of second uplink information are The information is multiplexed and transmitted; when at least one of the Z pieces of second indication information respectively included in the Z pieces of second downlink control information has a value other than the first preset value, it indicates that the N pieces of first indication information cannot be The uplink information and the M pieces of second uplink information are multiplexed and transmitted.

It can be seen that, in this embodiment, the network device instructs the terminal device not to distinguish the priorities of the first uplink channel and the second uplink channel, but to give priority to the indication information corresponding to the uplink information scheduled through the downlink control information, and to indicate The terminal device determines, according to the indication information, whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information. Since the terminal equipment does not need to distinguish priorities, the network equipment is more flexible in scheduling the uplink information through the downlink control information, which can make the determination result more accurate.

It can be seen that, in this embodiment, the network device instructs the terminal device, even if it is determined that the priority of the first uplink channel is higher than the priority of the second uplink channel, however, since the first uplink information is all determined by high-level parameters The configuration is relatively fixed; and if there is downlink control information scheduling in the second uplink information, the scheduling method is relatively flexible. Therefore, at this time, even if the priority of the first uplink channel is high, the network device still instructs the terminal device to use the second indication information included in the downlink control information to determine whether to combine the N pieces of first uplink information with the M pieces of second uplink information Multiplexing transmission can make the precision of the indication result higher.

In some possible implementations, L pieces of first uplink information in the N pieces of first uplink information are scheduled through L pieces of first downlink control information, and R pieces of the M pieces of second uplink information The second uplink information is scheduled through R pieces of second downlink control information, where L and R are both integers greater than or equal to 1, L is less than or equal to N, and R is less than or equal to M; the fifth downlink control information includes The third indication information is used to indicate whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information; wherein, the fifth downlink control information is L pieces of first downlink control information and the last downlink control information received by the terminal device in the R pieces of second downlink control information, and the third indication information is the first indication information or the second indication information.

It can be understood that when the value of the third indication information included in the fifth downlink control information is the first preset value, it indicates that the N pieces of first uplink information and the M pieces of second uplink information are multiplexed and transmitted. ; when the value of the third indication information included in the fifth downlink control information is not the first preset value, indicating that the N pieces of first uplink information and the M pieces of second uplink information cannot be multiplexed and transmitted.

It can be seen that, in the case of not distinguishing priorities, the network device instructs the terminal device to preferentially determine whether to perform the N pieces of first uplink information and the M pieces of second uplink information according to the indication information included in the downlink control information. multiplexed transmission, and instructs the terminal device to use the indication letter included in the last received downlink control information to determine whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information, thereby improving the Flexibility of network device indication, and fault tolerance.

In some possible implementations, L pieces of first uplink information in the N pieces of first uplink information are scheduled through L pieces of first downlink control information, and R pieces of the M pieces of second uplink information The second uplink information is scheduled through the R second downlink control information, where L and R are both integers greater than or equal to 1, L is less than or equal to N, and R is less than or equal to M; when the L first The values of the L pieces of first indication information included in the downlink control information are all first preset values, and the values of the R pieces of second indication information included in the R pieces of first downlink control information are all the first values of the first indication information. A preset value, indicating that the N pieces of first uplink information and the M pieces of second uplink information are multiplexed and transmitted.

It can be understood that when at least one of the L pieces of first indication information contained in the L pieces of first downlink control information and the R pieces of second indication information contained in the R pieces of first downlink control information has a value other than the first indication information. When a preset value is used, it indicates that the N pieces of first uplink information and the M pieces of second uplink information cannot be multiplexed and transmitted.

It can be seen that, in this embodiment, the network device instructs the terminal device to determine whether to use the N pieces of first uplink information according to the value of the indication information included in all downlink control information without distinguishing priorities. Multiplexing and transmission with the M pieces of second uplink information can further improve the accuracy of the indication.

In some possible implementations, the N pieces of first uplink information are configured by N first layer parameters, and the M pieces of second uplink information are configured by M second layer parameters, wherein each The first high-layer parameter includes a first indication information, and each second high-layer parameter includes a second indication information; when the N first indication information included in the N first high-layer parameters are all the first preset values value, and the values of the M pieces of second indication information included in the M pieces of second high-level parameters are all the first preset values, indicating that the N pieces of first uplink information are combined with the M pieces of second uplink information. information is multiplexed.

It can be seen that, in this implementation manner, the network device instructs the terminal device to determine, according to the values of all the first indication information and all the second indication information, when the priority is not differentiated and both are scheduled by high-level parameters. Whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information can ensure the accuracy of the indication.

In some possible implementation manners, when the values of the N pieces of first indication information are all the first preset values, and the values of the M pieces of second indication information are all the first preset values, Indicates that the N pieces of first uplink information and the M pieces of second uplink information are multiplexed and transmitted.

It can be seen that the network device instructs the terminal device to determine whether to perform multiplexing transmission according to the acquired values of all the indication information. Since all the values of the indication information are used for indication, the result of the indication can be more accurate.

The various UEs described above, if they are located on the vehicle (for example, placed in the vehicle or installed in the vehicle), can be considered as on-board user equipment, and the on-board user equipment is also called an on-board unit (OBU). , which is not limited in the embodiments of the present application.

In this case, the AN device coordinates the Attribute management of air interface. This embodiment of the present application does not limit the AN device.

In order to facilitate the understanding of the present application, the related technical knowledge involved in the embodiments of the present application is first introduced here.

In order to better support the multiplexing and transmission of mixed services, in the 3rd Generation Partnership Project (3GPP) Release16 protocol version, the division of physical layer priorities is introduced, and the uplink information can be classified according to the corresponding service type. It is divided into high priority (HP) uplink information or low priority (Low priority, LP) uplink information. Correspondingly, the uplink channel carrying uplink information can also be divided into high priority uplink channel and low priority. the upstream channel. If the Physical Uplink Control Channel (PUCCH) of the same priority overlaps with the Physical Uplink Shared Channel (PUSCH), the uplink information carried in the PUCCH and PUSCH can be directly multiplexed and transmitted; If uplink channels with different priorities overlap, multiplexing and transmission of the carried uplink information is not allowed. It is necessary to abandon the uplink information carried by the low-priority uplink channels at the overlapping time domain resource positions, and only transmit the high-priority uplink information. Uplink information carried by the uplink channel. However, if the transmission of the low-priority uplink channel does not affect the transmission of the high-priority uplink channel, and the multiplexing transmission is directly abandoned, the transmission efficiency of the low-priority uplink channel will be affected. On the contrary, if the multiplexing transmission is performed directly, it may bring transmission delay to the transmission of the high-priority uplink channel, reduce the transmission efficiency, and affect the reliability of its transmission.

It can be understood that the uplink information carried in one uplink channel in this application has the same physical layer priority, so the priority of the uplink channel can be represented by the priority of the uplink information carried by the uplink channel. Correspondingly, the different priorities of the uplink channels also refer to the different priorities of the uplink information carried by the uplink channels. In this way, the priority of uplink channel #1 is higher than the priority of uplink channel #2, which is equivalent to that the priority of uplink information #1 carried by uplink channel #1 is higher than the priority of uplink information #2 carried by uplink channel #2 class. That is to say, uplink channels of different priorities or uplink information carried by uplink channels of different priorities have a priority order, that is, uplink information of high priority and uplink information of low priority are included.

Referring to Figure 1, as shown in the left figure in Figure 1, the first PUCCH (PUCCH1) is the HP PUCCH, and the second PUCCH (PUCCH2) is the LP PUCCH, because before the HP UCI carried by the HP PUCCH is transmitted, the terminal device is still idle At this time, the LP uplink control information (UCI) carried by the LP PUCCH can be multiplexed with the HP UCI carried in the HP PUCCH, and the joint uplink control information (joint UCI) can be carried in the first The transmission on the three PUCCHs (PUCCH3) does not bring delay to the transmission of the HP UCI carried by the HP PUCCH. However, if the multiplexing transmission is abandoned at this time, the transmission efficiency of the LP UCI carried by the LP PUCCH will be affected. As shown in the right figure in Figure 1, there may be no idle time domain resources before the HP UCI carried by the HP PUCCH is transmitted. At this time, the LP UCI carried by the LP PUCCH and the HP UCI carried by the HP PUCCH are multiplexed on PUCCH3 Transmission, the end time of multiplex transmission is greater than the end time of HP PUCCH. Therefore, if the uplink information carried by the LP PUCCH and the HP PUCCH is directly multiplexed and transmitted, it will bring a delay to the transmission of the HP UCI carried by the HP PUCCH and affect the transmission efficiency of the HP service.

To sum up, the terminal equipment performs multiplexing transmission or abandons multiplexing transmission in a relatively simple manner, which affects the transmission efficiency.

First, the related concepts involved in the present application are introduced to facilitate understanding of the present application.

1. Classification of uplink channels.

Uplink channels include PUCCH and PUSCH. The PUCCH is used to carry the uplink control information UCI, and the PUSCH is used to carry the uplink control information UCI and/or data data. Among them, UCI includes at least one of the following:

Hybrid Automatic Repeat Request (HARQ) for Physical Downlink Shared Channel (PDSCH) - Acknowledgement or Negative Acknowledgement (ACK/NACK), referred to as HARQ-ACK, Channel State Information (Channel State) Information, CSI), and the CSI includes Periodic (Periodic, P)-CSI, Semi-Persistent (SP)-CSI and Aperiodic (Aperiodic, A)-CSI, Scheduling Request (Scheduling Request, SR) , Beam Failure Recovery (BFR).

2. The scheduling method of uplink information.

The scheduling methods of uplink information include the following three types: downlink control information (downlink control information, DCI) scheduling, high-level parameter configuration, and high-level parameter configuration, but requires DCI activation.

2.1. When the transmission of uplink information is DCI scheduling, the uplink information includes at least one of the following:

HARQ-ACK of PDSCH scheduled by DCI, uplink data, and A-CSI triggered by DCI, including A-CSI on PUCCH and A-CSI on PUSCH.

2.2. When the transmission of uplink information is configured by high-level parameters, the uplink information includes at least one of the following:

SR, the corresponding high-level parameter is the PUCCH resource configuration parameter of the SR;

BFR, the corresponding high-level parameter is the PUCCH resource configuration parameter of the BFR;

The data carried in the Type-1 CG PUSCH, the Type-1 CG PUSCH is the first type (Type-1) in the Configured Grant (CG)-PUSCH, and the corresponding high-level parameters are the Type-1 CG configuration parameters.

2.3. When the transmission of uplink information is configured by high-level parameters, but DCI activation is required, the uplink information includes at least one of the following:

The data carried in the Type-2 CG PUSCH, the Type-2 CG PUSCH is the first type (Type-2) in the CG-PUSCH, and the corresponding high-level parameters are the Type-2 CG configuration parameters;

SP-CSI on PUSCH, the corresponding high-level parameters are SP CSI report configuration parameters;

Semi-persistent scheduling (Semi-Persistent-Scheduling, SPS) - HARQ-ACK of PDSCH, the corresponding high-level parameter is the SPS configuration parameter, that is, SPS Config.

3. Indication method of uplink information priority.

3.1. HARQ-ACK of PDSCH scheduled by DCI: The network device indicates the priority of HARQ-ACK by adding a 1-bit priority indicator field in the DCI;

3.2. HARQ-ACK of SPS-PDSCH: The network device indicates the priority of SPS-PDSCH by adding 1bit priority Indicator to the SPS configuration parameter (ie, SPS Config);

It should be noted that the SPS PDSCH is activated through DCI, and the DCI used for activation also has a 1-bit priority indictor field, but this field is automatically invalid and will not rewrite the priority indicated in the SPS Config.

3.3. SR or BFR: The network device indicates the priority of the SR or BFR by adding a 1bit priority Indicator parameter to the radio resource control parameter of the PUCCH resource corresponding to the SR or BFR;

3.4. CSI on PUCCH: For P-CSI and SP-CSI, the default is low priority; for A-CSI on PUCCH, the network device indicates the priority by triggering 1bit priority indicator in the DCI of the A-CSI. Priority of level A-CSI.

The technical solutions of the present application will be described in detail below with reference to the accompanying drawings.

Referring to FIG. 2, FIG. 2 is a schematic structural diagram of a communication system according to an embodiment of the present application. The communication system 10 includes a terminal device 100 and a network device 200 . The terminal device 100 acquires first indication information, the first indication information corresponds to N pieces of first uplink information, and the N pieces of first uplink information are carried on the first uplink channel; the terminal device 100 also acquires M pieces of second indication information, the M pieces of first uplink information are The pieces of second indication information correspond to the M pieces of second uplink information, and the M pieces of second uplink information are carried on the second uplink channel; the terminal device 100 determines whether the N pieces of first uplink information and/or the M pieces of second indication information Multiplexing and transmitting the N pieces of first uplink information and the M pieces of second uplink information; wherein, the priorities of the first uplink channel and the second uplink channel are different, and the first uplink channel and the second uplink channel have different priorities. The channels overlap in time domain, and the overlapping time domain resource is the first time domain resource, and both N and M are integers greater than or equal to 1.

Optionally, the first indication information may be included in the first DCI or the first high-layer parameter sent by the network device 200 to the terminal device 100, where the first DCI is used to schedule the transmission of the first uplink information, so The first higher layer parameter is used to configure the transmission of the first uplink information, and may be radio resource control (radio resource control, RRC) signaling. The first indication information corresponding to a piece of first uplink information is used to indicate whether the uplink information can be multiplexed and transmitted with uplink information of different priorities.

Optionally, the second indication information may be included in the second DCI or the second higher layer parameter sent by the network device 200 to the terminal device 100, where the second DCI is used to schedule the transmission of the second uplink information, so The second higher layer parameter is used to configure the transmission of the second uplink information, and may be RRC signaling. The second indication information corresponding to a piece of second uplink information is used to indicate whether the uplink information can be multiplexed and transmitted with uplink information of different priorities.

Optionally, the priority of the first uplink channel is the priority of the N pieces of first uplink information, and the N pieces of first uplink information have the same priority.

Optionally, the priority of the second uplink channel is the priority of the M pieces of second uplink information, and the M pieces of second uplink information have the same priority.

Optionally, the priority refers to a physical layer priority, which is used to implicitly indicate a service type corresponding to the uplink information or a service delay or reliability requirement.

Optionally, the time domain of the first uplink channel and the second uplink channel overlap, which means that the time domain resources of the first uplink channel and the time domain resources of the second uplink channel include at least one same time unit, and the Time units may be slots and/or symbols. For example, the time domain resources of the first uplink channel are symbols #1 to #6 in time slot #3, the time domain resources of the second uplink channel are symbols #4 to #9 in time slot #3, and the time unit is a symbol , then the same time units included in the two are symbols #4 to #6 in time slot #3. Correspondingly, the overlapping time domain resources, that is, the first time domain resources, correspond to symbols #4 to #6 in time slot #3.

When the terminal device 100 determines that the N pieces of first uplink information and the M pieces of second uplink information are multiplexed and transmitted, then the Nth first uplink information and the M pieces of second uplink information are multiplexed and transmitted, This includes multiplexing the N pieces of first uplink information and the M pieces of second uplink information, and sending the multiplexed joint uplink information to the network device 200 on the third uplink channel. Wherein, the third upstream channel may be one of the first upstream channel or the second upstream channel, or may be another upstream channel different from the first upstream channel and the second upstream channel. The determination method of the third uplink channel may be any determination method, which is not particularly limited in this application.

When the terminal device 100 determines that the N pieces of first uplink information and the M pieces of second uplink information cannot be multiplexed and transmitted, the terminal device 100 sends the first time-domain resource location to the network device 200 to transmit the first link carried by the first uplink channel to the network device 200. Uplink information, and give up sending the second uplink channel to the network device 200 at the first time domain resource position, where the priority of the first uplink channel is higher than that of the second uplink channel. Optionally, giving up sending the second uplink channel to the network device 200 at the first time domain resource location may also mean not sending the second uplink channel at the first time domain resource location or canceling the sending of the second uplink channel. . Optionally, discarding/not sending/cancelling sending the second uplink channel at the first time domain resource position, including part or all of the second uplink information originally carried on the first time domain resource and the second uplink channel will also be used. Discard send/don't send/cancel send.

It can be seen that, in this embodiment of the present application, the terminal device 200 determines whether it can be Multiplexing and transmitting N pieces of first uplink information and M pieces of second uplink information, instead of simply performing multiplexing transmission directly or abandoning multiplexing transmission, thereby improving the process of multiplexing transmission or abandoning multiplexing transmission for terminal equipment The flexibility in the network can not only prevent multiplexing from affecting the delay and reliability of high-priority service transmission, but also improve the transmission efficiency of low-priority services.

Referring to FIG. 3 , FIG. 3 is a schematic flowchart of a method for uplink transmission provided by an embodiment of the present application. The method includes the following steps:

301: A terminal device acquires N pieces of first indication information, where the N pieces of first indication information correspond to N pieces of first uplink information, and the N pieces of first uplink information are carried on a first uplink channel.

Exemplarily, the first uplink channel includes the first PUCCH or the first PUSCH. Each of the N pieces of first uplink information may be a first UCI or data (data). The first UCI includes at least one of the following: HARQ-ACK, P-CSI, SP-CSI, A-CSI, SR, and BFR.

Exemplarily, there are three scheduling methods for uplink information: (1) the network device is scheduled by DCI, (2) configured by high-level parameters, and (3) configured by high-level parameters, but DCI activation is required. Therefore, the N pieces of first uplink information may be obtained by the network device performing scheduling through one or more of the above three scheduling methods, and each scheduling method will include the first indication information; The device obtains the N pieces of first indication information for the scheduling mode of the N pieces of first uplink information.

It should be noted that for the high-level parameter configuration, but the scheduling method of DCI activation is required, the first indication information included in the DCI may be the first indication information included in the DCI used during activation, or the first indication included in the high-level configuration parameters. information, not limited here. That is to say, in the following description, "the network device is scheduled by DCI" includes "the network device is scheduled by the DCI" and/or "the network device is configured by high-level parameters, but requires DCI activation", and "the network device is configured by high-level parameters" includes " The network device is configured by high-level parameters" and/or "The network device is configured by high-level parameters, but requires DCI activation".

The manner in which the terminal device acquires the N pieces of first indication information will be described in detail below with reference to a specific scheduling manner.

(1) Scenario 1: The N pieces of first uplink information are scheduled by the network device through the N pieces of first DCI.

Exemplarily, the N pieces of first uplink information are all scheduled by the network device through the N pieces of first DCI, where each first DCI includes one piece of first indication information. For example, a field may be added to each first DCI, and the first indication information may be carried by the field; or, an existing field in each first DCI may be multiplexed, and the first indication information may be carried by the field. The first indication information may be used to indicate whether the uplink information scheduled by the DCI can be multiplexed with uplink information of different priorities. Therefore, the terminal device can obtain the N first indication information by parsing a new or existing field in each first DCI.

(2) Scenario 2: N pieces of first uplink information are configured by N pieces of first higher layer parameters.

Exemplarily, the N pieces of first uplink information are all configured by the network device through N pieces of first higher layer parameters, where each first higher layer parameter includes one piece of first indication information. For example, a field may be added to each first high-level parameter, and the first indication information may be carried by the field. Alternatively, an existing field in each of the first high-layer parameters may be multiplexed, and the first indication information may be carried by the field. Therefore, the terminal device can obtain the N pieces of first indication information by parsing a new or existing field in each first high-level parameter. The first indication information may be used to indicate whether the uplink information carried by the uplink channel configured by the high layer parameter can be multiplexed with uplink information of different priorities. Here, the high-level parameter may be RRC signaling, and a field included in the high-level parameter may be an information element (Information element) in the RRC signaling.

(3) Scenario 3: The X pieces of first uplink information among the N pieces of first uplink information are scheduled by the network equipment through the X pieces of first DCI, and the remaining Y pieces of first uplink information are configured by the network equipment through the Y pieces of first high-level parameters , where X+Y=N, and both X and Y are integers greater than or equal to 1.

Exemplarily, a part of the first uplink information in the N first uplinks, that is, the X first uplink information, is scheduled by the network device through the X first DCIs, wherein each first DCI includes a first indication information; the other part of the first uplink information, that is, the Y first uplink information, is configured by the network device through the Y first upper layer parameters.

The method for obtaining the X pieces of first indication information is similar to the method for obtaining the first indication information in the above situation 1, and the method for obtaining the Y pieces of first indication information for the Y pieces of first uplink information is the same as the method for obtaining the first indication information in the above situation 2. The method for obtaining the indication information is similar, and the description is not described here.

For example, the first uplink channel is PUCCH, part of the first uplink information carried by it may be the HARQ-ACK of the PDSCH scheduled by the network device through the first DCI, and the rest of the first uplink information may be the network device through the first high layer parameter HARQ-ACK or SR or CSI of the configured SPS PDSCH; for another example, a part of the first uplink information may be the HARQ-ACK of the PDSCH scheduled by the network device through the first DCI, and the rest of the first uplink information may be the network device through the first Data carried by Type-1 CG PUSCH configured by high-level parameters.

302: The terminal device acquires M pieces of second indication information, where the M pieces of second indication information correspond to the M pieces of second uplink information, and the M pieces of second uplink information are carried on the second uplink channel.

The priorities of the first upstream channel and the second upstream channel are different, that is, one of the first upstream channel and the second upstream channel is a high-priority upstream channel, and the other is a low-priority upstream channel. In addition, the first uplink channel and the second uplink channel overlap in time domain, that is, there is an overlapping part between the time domain resource corresponding to the first uplink channel and the time domain resource corresponding to the second uplink channel, and the overlapping time domain The domain resource is the first time domain resource.

Exemplarily, the second uplink channel includes a second PUCCH or a second PUSCH. Each of the N pieces of second uplink information may be second UCI or data. Wherein, the second UCI includes at least one of the following: HARQ-ACK, P-CSI, SP-CSI, A-CSI, SR, and BFR.

The scheduling manner of the M pieces of second uplink information is similar to the scheduling manner of the above N pieces of first uplink information, and will not be described again. When the second indication information is indicated by a field in the second DCI, the second indication information is used to indicate whether the uplink information scheduled by the second DCI can be multiplexed with uplink information of different priorities. The second indication information is indicated by a field in the second high layer parameter, and the second indication information is used to indicate whether the uplink information carried by the uplink channel configured by the second high layer parameter can be multiplexed with uplink information of different priorities. The manner of acquiring the M pieces of second indication information and the above manner of acquiring the N pieces of first indication information will not be described in detail.

Optionally, the priority of the uplink channel refers to the physical layer priority, which is used to implicitly indicate the service type corresponding to the uplink information carried by the uplink channel or the time delay or reliability requirement of the service.

Optionally, step 302 may not be performed. For example, in Example 1 below, when the priority of the first uplink channel is higher than the priority of the second uplink channel, the terminal device only determines whether to combine the N pieces of first uplink information with the M pieces of second uplink information only according to the N pieces of first indication information. The uplink information is multiplexed and transmitted. At this time, the terminal device does not need to acquire M pieces of second indication information. That is to say, in some methods, the terminal device only needs to acquire the indication information (first indication information or second indication information) corresponding to the uplink information of high priority, and does not need to acquire the indication information corresponding to uplink information of low priority.

Optionally, the obtaining of the N pieces of first indication information includes: receiving the N pieces of first indication information from a network device.

Optionally, obtaining the M pieces of second indication information includes: receiving the M pieces of second indication information from a network device.

Optionally, in one embodiment, the terminal device may receive DCI or high-layer parameters including the M pieces of second indication information, but not acquire the M pieces of second indication information from the DCI or high-layer parameters, or That is, the M pieces of second indication information are not used.

303: The terminal device determines, according to the N pieces of first indication information and/or the M pieces of second indication information, whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information.

Each first indication information is used to indicate whether to multiplex and transmit the corresponding first uplink information and uplink information of different priorities; each second indication information is used to indicate whether to combine the corresponding second uplink information with different priorities The uplink information is multiplexed and transmitted. Therefore, the terminal device may determine whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information according to the N pieces of first indication information and/or the M pieces of second indication information.

Moreover, when it is determined that the N pieces of first uplink information and the M pieces of second uplink information are multiplexed and transmitted, the terminal device may multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information, For example, the N pieces of first uplink information and the M pieces of second uplink information can be multiplexed on the third uplink channel for joint transmission; when it is determined that the N pieces of first uplink information and the M pieces of second uplink information cannot be When performing multiplexing transmission, the terminal device can send the uplink information carried by the high-priority uplink channel to the network device at the first time-domain resource location, and give up sending the low-priority uplink information to the network device at the first time-domain resource location. Uplink information carried by the channel. In addition, when it is determined that the N pieces of first uplink information and the M pieces of second uplink information cannot be multiplexed and transmitted, the uplink information carried by the low-priority uplink channel may be discarded at the first time domain resource position. For transmission, only the uplink information carried by the high-priority uplink channel is transmitted, and the description will not be repeated.

The following examples 1 to 4 provide several ways of how to determine whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information. It can be understood that the following examples are not enough to set any limitation to the present application.

Example 1: The terminal device determines whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information according to the indication information corresponding to the high-priority uplink channel.

Optionally, the terminal device determines the priority of the first uplink channel and the priority of the second uplink channel.

It should be noted that in this solution, even if the terminal device receives the indication information corresponding to the low-priority uplink channel, it only determines whether to associate the N pieces of first uplink information with the M pieces of information based on the indication information corresponding to the high-priority uplink channel The second uplink information is multiplexed and transmitted.

Based on the above, it can be known that each uplink information corresponds to a priority indicator field. Therefore, the terminal device may determine the priority of each first uplink information according to the priority indicator field corresponding to each first uplink information, and assign one or more of the N pieces of first uplink information to the priority of each first uplink information. A priority of the uplink information, as the priority of the first uplink channel. Likewise, the terminal device may use the priority of one or more pieces of second uplink information among the M pieces of second uplink information as the priority of the second uplink channel.

In this application, the priority of the first uplink channel is higher than the priority of the second uplink channel as an example for description. The situation where the priority of the second uplink channel is higher than the priority of the first uplink channel is similar to that of the first uplink channel is higher than the priority of the second uplink channel, and the description will not be repeated.

Understandably, the following 1.1-1.3 are descriptions of different implementations listed in Example 1 according to different sources of uplink information. In addition, it should be pointed out that "determining (whether) to perform multiplexing transmission" described in this application may mean "determining (whether) multiplexing the N pieces of first uplink information with the M pieces of second uplink information. Use transmission" or "determine (whether) to multiplex and transmit the first uplink information and the second uplink information" or "determine (whether) to perform multiplex transmission of the uplink information" and other similar meanings, which will not be repeated.

1.1. For the case where the N pieces of first uplink information are scheduled through the N pieces of first DCI.

The case where the N first uplink information is scheduled by the N first DCIs may include the following manners. It should be understood that the following scheduling methods do not limit the present application.

Optionally, the first uplink channel is the first PUCCH that carries HARQ-ACK, the first PUCCH carries HARQ-ACK information corresponding to N first PDSCHs, and the N first PDSCHs are scheduled by N first DCIs, each of which is scheduled by N first DCIs. The first DCI includes a piece of first indication information, and each first indication information is used to indicate whether the HARQ-ACK of the first PDSCH scheduled by the first DCI corresponding to the first indication information can be processed with uplink information of different priorities. Multiplex transmission.

Optionally, the first uplink channel is the first PUCCH that carries HARQ-ACK and A-CSI, the first PUCCH carries HARQ-ACK information corresponding to N1 first PDSCHs and N2 A-CSI information, the N1 The first PDSCH is scheduled by N1 first DCIs, the N2 A-CSIs are scheduled by N2 first DCIs, and each first DCI includes one first indication information, which is used to indicate the first DCI scheduled by the first DCI. Whether HARQ-ACK and/or A-CSI of a PDSCH can be multiplexed and transmitted with uplink information of different priorities, where N1 is less than or equal to N, N2 is less than or equal to N, and N=N1+N2. In addition, the N2 first DCIs may be different DCIs from the N1 first DCIs, or may be the same DCI, which is not limited in this application.

Optionally, the first uplink channel is the first GB PUSCH carrying data and/or A-CSI, and is scheduled by a first DCI (that is, N=1), the first DCI includes a first indication information, and The first indication information is used to indicate whether the data and/or A-CSI carried by the first GB PUSCH scheduled by the first DCI can be multiplexed and transmitted with uplink information of different priorities.

Optionally, the first uplink channel is the first GB PUSCH carrying data and HARQ-ACK, wherein data is scheduled by N1 first DCIs, and HARQ-ACK is scheduled by N2 (N2=N-N1) first DCIs, Each first DCI contains a piece of first indication information, and each first indication information is used for whether the data or HARQ-ACK scheduled by the first DCI corresponding to the first indication information can be performed with uplink information of different priorities. Multiplex transmission.

Exemplarily, when the priority of the first uplink channel is higher than the priority of the second uplink channel, and the N pieces of first uplink information are scheduled through the N pieces of first DCI, the terminal device can be based on the N pieces of first indication information. part or all of the first indication information, and determine whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information.

The following 1.1.1-1.1.2 are examples of how to determine whether to perform multiplexing transmission according to the first indication information in the embodiment of 1.1.

1.1.1. Determine whether to perform multiplexing transmission according to the first indication information included in the first DCI last received by the terminal device.

Exemplarily, when the priority of the first uplink channel is higher than the priority of the second uplink channel, and the N pieces of first uplink information are scheduled through the N pieces of first DCI, the terminal device may, according to the No. An indication message for determining whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information. The third downlink control information is the first DCI received by the terminal device last among the N first DCIs.

When the network device schedules the N pieces of first uplink information through the N pieces of first DCI, it will send the N pieces of first DCI to the terminal device at multiple pre-configured time domain locations, and the terminal device will send the N pieces of first DCI information at the multiple time domain locations The N first DCIs sent by the network device are blindly detected. Therefore, the last received first DCI is the last blindly detected first DCI by the terminal device. Wherein, the blind detection of DCI means that the terminal device needs to attempt to receive DCI at multiple candidate positions (eg, frequency domain positions) of each receiving time domain position, and assume different DCI formats (corresponding to different load sizes) for decoding. And cyclic redundancy check (Cyclic Redundancy Check, CRC), when a candidate position is combined with a certain DCI format and passes the CRC, it is considered that the blind detection is successful, that is, a DCI is blindly detected.

It should be noted that a network device may send multiple DCIs at one time domain location. Correspondingly, the terminal device may finally blindly detect multiple first DCIs. Optionally, in this case, the terminal device may take the target first DCI among the plurality of first DCIs blindly detected last as the last first DCI, and the first indication included in the target first DCI When the information indicates that uplink information of different priorities can be multiplexed and transmitted, the terminal device determines to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information. Exemplarily, the target first DCI may be the first DCI with the largest carrier number among a plurality of first DCIs that are blindly detected last by the terminal device. Optionally, in this case, the terminal device may regard the multiple first DCIs blindly detected last as the third DCI, and only if multiple first indication information included in the multiple first DCIs indicates that the When performing multiplexing and transmission with uplink information of different priorities, the terminal device determines to perform multiplexing and transmission of the N pieces of first uplink information and the M pieces of second uplink information.

In addition, the interpretation of the DCI finally received by the terminal equipment involved in the following is similar to the above, and the description is not repeated.

Exemplarily, when the value of the first indication information included in the third downlink control information is a first preset value, it is determined that the N pieces of first uplink information and the M pieces of second uplink information are multiplexed and transmitted, such as , when the indication information is carried by adding a field in the DCI, when the value of the field is 1, that is, when the value of the first indication information is 1, it is determined that the N pieces of first uplink information are combined with M pieces of second uplink information are multiplexed and transmitted; when the value of the first indication information included in the third downlink control information is not the first preset value, it is determined that the N pieces of first uplink information cannot be combined with the M pieces of second uplink information. The uplink information is multiplexed and transmitted. For example, when the value of the first indication information is 0, it is determined that the N pieces of first uplink information and the M pieces of second uplink information cannot be multiplexed and transmitted.

It should be noted that, in practical applications, it is also possible to determine whether to multiplex the N pieces of first uplink information with the M pieces of second uplink information according to the first indication information included in any one of the N first DCIs. Transmission, which is not limited in this application.

It can be seen that the terminal device only needs to determine whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information according to the last received first DCI, and does not need to pay attention to other first DCIs. In this way, in the process of indicating whether the N pieces of first uplink information and M pieces of second uplink information are multiplexed and transmitted, the network device can only pay attention to the last first DCI, and the indication method is more flexible; in addition, from the time domain point of view , the time domain position of the first DCI last received by the terminal device is generally also a DCI closest to the start position of the first uplink channel, and the indication result in the first DCI is used to determine whether the N pieces of first uplink information can be combined with It is also more accurate to multiplex and transmit the M pieces of second uplink information; moreover, the network device can use this first DCI to indicate, and can also adjust and correct the first DCI with an indication error, which improves the accuracy of the indication process of the network device. fault tolerance.

1.1.2. Determine whether to perform multiplexing transmission according to the N pieces of first indication information.

Exemplarily, when the values of the N pieces of first indication information are exactly the same, it is determined that the N pieces of first uplink information and the M pieces of second uplink information are multiplexed and transmitted; when the values of the N pieces of first indication information are multiplexed and transmitted; When the values are not identical, it is determined that the N pieces of first uplink information and the M pieces of second uplink information cannot be multiplexed and transmitted.

Further, when the values of the N pieces of first indication information are completely the same and all are the first preset values, it is determined that the N pieces of first uplink information and the M pieces of second uplink information are multiplexed and transmitted; When at least one of the N pieces of first indication information has a value other than the first preset value, it is determined that multiplexing and transmission of the N pieces of first uplink information and the M pieces of second uplink information is not allowed. For example, when the values of the N pieces of first indication information are all 1, it is determined that the N pieces of first uplink information and the M pieces of second uplink information are multiplexed and transmitted.

It can be seen that whether the N pieces of first uplink information and the M pieces of second uplink information are multiplexed and transmitted is determined by including all the first indication information in the N pieces of first DCI, which can ensure the accuracy of the determination result. Moreover, in practical applications, although the network device sends the first DCI at the last time domain position, it does not guarantee that the terminal device can successfully blindly detect the first DCI, and there will be a first DCI included in the last first DCI. A problem that indicates information loss. The terminal device determines whether to multiplex and transmit N pieces of first uplink information and M pieces of second uplink information according to the values of the first indication information included in all the received first DCIs, even if the last first DCI is lost. In this case, it can still be accurately determined whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information.

Optionally, the terminal device does not expect the first indication information contained in the N first DCIs to have different values. In this case, the terminal device determines whether to compare the N first uplink information with the M first indication information according to the N first indication information. Multiplexing and transmitting the two uplink information is equivalent to determining whether to multiplex the N pieces of first uplink information with the M pieces of second uplink information according to the value of any one of the N pieces of first indication information For transmission, as long as the value of the first indication information is the first preset value, it can be determined that the N pieces of first uplink information and the M pieces of second uplink information are multiplexed and transmitted.

In practical applications, it is also possible to only consider whether the values of part of the first indication information in the N pieces of first DCI indication information are all the same or the first preset value to determine whether to perform multiplexing transmission. Whether the last two pieces of first indication information in the N pieces of first indication information are both the first preset value or the same, and if the last two first indication information are both the first preset value, it is determined that the uplink information can be performed multiplex transmission. The present application does not limit the quantity and location of the first indication information.

1.2. For the case where the N pieces of first uplink information are configured through N pieces of first high-layer parameters.

The case where the N pieces of first uplink information are configured by N pieces of first high-layer parameters may include the following configuration modes. It should be understood that the following configuration manners do not limit the present application.

Optionally, the first uplink channel is the first PUCCH that carries the HARQ-ACK or SR corresponding to the SPS PDSCH, and the first PUCCH carries the HARQ-ACK information corresponding to N SPS PDSCHs, or, 1 SR; or, the first The PUCCH carries the HARQ-ACKs and N2 (N2=N-N1) SRs corresponding to N1 SPS PDSCHs, and the first high layer parameters of each SPS PDSCH or the first high layer parameters of each SR or the PUCCH resource configuration parameters of the SR include A first indication information, the first indication information is used for whether the HARQ-ACK or SR corresponding to the SPS PDSCH configured by the high layer parameter can be multiplexed and transmitted with uplink information of different priorities.

Optionally, the first uplink channel is the first CG PUSCH bearing data, and the first uplink channel corresponds to a CG PUSCH high-level configuration parameter (the first high-level parameter), that is, N=1. Moreover, the high-level configuration parameter includes a first indication information, and the first indication information is used to indicate whether the data carried by the CG PUSCH configured by the high-level parameter can be multiplexed and transmitted with uplink information of different priorities.

Optionally, the first uplink channel is the first CG PUSCH that carries data and SPS PDSCH corresponding to HARQ-ACK, the data carried by the first uplink channel corresponds to a CG PUSCH high-level configuration parameter (first high-level parameter), the first uplink The channel carries the HARQ-ACK corresponding to the SPS PDSCH corresponding to N1 (N1=N-1) SPS PDSCH high-level configuration parameters (the first high-level parameter), and each first high-level parameter includes a first indication information, and the first indication information is used. Indicates whether the HARQ-ACK corresponding to the data carried by the CG PUSCH or the SPS PDSCH configured by the first higher layer parameter can be multiplexed and transmitted with uplink information of different priorities.

The terminal device may determine whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information according to the N pieces of first indication information included in the N pieces of first high-layer parameters.

Exemplarily, when the values of the N pieces of first indication information are completely the same or the values are completely the same and all are the first preset values, it is determined that the N pieces of first uplink information and the M pieces of second uplink information are performed. Multiplex transmission; otherwise, it is determined that multiplex transmission of the N pieces of first uplink information and the M pieces of second uplink information is not allowed.

It can be seen that only when the values of the N pieces of first indication information included in the N pieces of first high-level parameters are all the first preset values, the terminal device will combine the N pieces of first uplink information with the M pieces of first uplink information. The two uplink information is multiplexed and transmitted, so that the process of multiplexing and transmitting the N pieces of first uplink information and the M pieces of second uplink information is more accurate.

Optionally, the terminal device does not expect the first indication information contained in the N first high-layer parameters to have different values. In this case, the terminal device determines whether to compare the N first uplink information with the M first indication information according to the N first indication information. The multiplexing and transmission of the second uplink information is equivalent to determining whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information according to any one of the first indication information in the N pieces of first indication information, As long as the value of the first indication information is the first preset value, it can be determined that the N pieces of first uplink information and the M pieces of second uplink information are multiplexed and transmitted.

1.3. For the case where the N pieces of first uplink information are both scheduled by the first DCI and configured by the first high layer parameters.

The case where the N pieces of first uplink information are both scheduled by the first DCI and configured with the first high-layer parameters may include the following manners. It should be understood that the following manners do not limit the present application.

Optionally, the X pieces of first uplink information are HARQ-ACKs of the first PDSCH scheduled by the X first DCIs, and the remaining Y pieces of first uplink information are the HARQs of the Y SPS PDSCHs configured by the Y first high-level parameters. -ACK.

Optionally, the X pieces of first uplink information are data carried by the GB PUSCH scheduled through a first DCI (that is, X=1), and the remaining Y pieces of first uplink information are Y SPSs configured through Y first high-level parameters. HARQ-ACK for PDSCH.

Exemplarily, if X pieces of first uplink information in the N pieces of first uplink information are scheduled by using X pieces of first downlink control information, and the remaining Y pieces of first uplink information are configured by using Y first high-level parameters . The terminal device may preferentially determine whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information according to the first indication information included in the first DCI. Therefore, the terminal device may determine whether to complex the N pieces of first uplink information and the M pieces of second uplink information according to some or all of the first indication information in the X pieces of first indication information respectively included in the X pieces of first uplink information. use transmission.

Wherein, the terminal device determines whether to multiplex and transmit N pieces of first uplink information and M pieces of second uplink information according to some or all of the first indication information in the X pieces of first indication information, see 1.1. The implementation methods in 1 and 1.1.2 will not be repeated.

In addition, the terminal device may also determine whether to convert the N first indication information according to the X pieces of first indication information respectively included in the X pieces of first downlink control information and the Y pieces of first indication information respectively included in the Y pieces of first high-level parameters The uplink information and the M pieces of second uplink information are multiplexed and transmitted. For example, when the X pieces of first indication information respectively included in the X pieces of first downlink control information and the Y pieces of first indication information respectively included in the Y pieces of first high-level parameters have the same value (or the values are the same and both are When the first preset value), it is determined that the N pieces of first uplink information and the M pieces of second uplink information are multiplexed and transmitted; otherwise, the N pieces of first uplink information and the M pieces of second uplink information cannot be multiplexed. transmission.

In the above, both X and Y are positive integers greater than or equal to 1, and N=X+Y.

Optionally, the terminal device does not expect the N pieces of first indication information to have different values. In this case, the terminal device determines whether to perform multiplexing of the N pieces of first uplink information with the M pieces of second uplink information according to the N pieces of first indication information. Using transmission is equivalent to determining whether to multiplex and transmit N pieces of first uplink information and M pieces of second uplink information according to any one of the first indication information in the N pieces of first indication information, as long as the first indication information is the first preset value, then it can be determined that the N pieces of first uplink information and the M pieces of second uplink information are multiplexed and transmitted.

It can be seen that both the first indication information included in the first DCI and the first indication information included in the first high-layer parameter are considered, thereby improving the accuracy of the determination result and further improving the transmission efficiency.

Optionally, in an embodiment of the present application, although in Example 1, the N pieces of first uplink information are scheduled through the N pieces of first DCI, the N pieces of first high-layer parameter configuration, or the N pieces of first uplink information. A part is scheduled by the first DCI, and the rest is configured by the first high-level parameter. However, the types of uplink information scheduled by different first DCIs or the types of uplink information configured by different first higher layer parameters may be different. Therefore, the types of the N pieces of first uplink information can be divided into P types, and each type includes one or more pieces of first uplink information. The terminal device may determine the first type of first uplink information according to the preset priorities among the P types of first uplink information, and determine the first type of first uplink information according to the first DCI or the first type of first uplink information corresponding to the first type of first uplink information. The first indication information included in a high layer parameter determines whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information. The preset priority may be a priority among multiple uplink information types preconfigured by the network device. For example, data>UCI, or, HARQ-ACK>CSI/SR, or, A-CSI>SPS PDSCH HRAQ-ACK/SR. The pre-configured priorities of the network devices mentioned later are similar to this and will not be repeated. In this application, the above-mentioned priority preset according to the type of uplink information may be referred to as a type priority.

Exemplarily, the first type of first uplink information may be the first uplink information with the highest priority among the P types of first uplink information, or the first uplink information with the lowest priority, which this application does not apply. Do limit.

It should be noted that this embodiment can have different combination modes with different situations in Example 1. For example, there are the following combination modes. The so-called combination is the combination of this embodiment and Example 1 in the execution order.

Optionally, in an implementation manner, the terminal device determines N1 pieces of first indication information from the N pieces of first indication information according to the method described in Example 1, and uses the N1 pieces of first indication information to determine whether it is possible to duplicate the information. use transmission; then according to the type priority, determine N2 first type of first uplink information from the N1 first uplink information corresponding to the N1 first indication information; then, according to the N2 first type of uplink information corresponding The first indication information is determined, and whether the N pieces of first uplink information and the M pieces of second uplink information can be multiplexed is determined, and the determination method is similar to the method in Example 1. Among them, N2 is less than or equal to N1, and N1 is less than or equal to N.

For example, referring to Example 1.1.1, the terminal device first determines that the first indication information included in the last received first DCI corresponding to the high-priority uplink channel is used to judge whether to perform multiplexing transmission; when the first DCI corresponds to more When there are pieces of first uplink information, the first uplink information of the first type in the plurality of first uplink information is determined according to the type priority of the plurality of first uplink information; the terminal device determines the first uplink information of the first type according to the determined first uplink information. The first indication information corresponding to the first uplink information of the type determines whether to perform multiplexing transmission.

For example, referring to Example 1.1.2, the terminal device first determines that the N pieces of first indication information included in the N pieces of first DCI corresponding to the high-priority uplink channel are used for judging to perform multiplexing transmission; and then, according to the type priority, N1 pieces of uplink information of the first type are determined from the N pieces of first uplink information; then, the terminal device determines whether to perform multiplexing according to the N1 pieces of first indication information corresponding to the determined N1 pieces of first type of first uplink information transmission. For example, when the values of the N1 pieces of first indication information are all the first preset values, it is determined that multiplexing transmission can be performed; otherwise, it is determined that multiplexing transmission cannot be performed.

For example, referring to Example 1.2, the terminal device first determines the N pieces of first indication information configured with the N first layer parameters corresponding to the uplink channel with high priority to be used for judging to perform multiplexing transmission; and then, according to the type priority, from N1 pieces of uplink information of the first type are determined from the N pieces of first uplink information; then, the terminal device determines whether to perform multiplexing transmission according to the N1 pieces of first indication information corresponding to the determined N1 pieces of first type of first uplink information . For example, when the values of the N1 pieces of first indication information are all the first preset values, it is determined that multiplexing transmission can be performed; otherwise, it is determined that multiplexing transmission cannot be performed.

For example, referring to Example 1.3, consider the case where X pieces of first uplink information among the N pieces of first uplink information on a high-priority uplink channel are scheduled through DCI, and Y pieces of first uplink information are configured through high-level parameters, where N=X+Y. The terminal device may first determine that the X pieces of first indication information included in the X pieces of first DCI corresponding to the high-priority uplink channel are used for judging to perform multiplexing transmission; and then, according to the type priority, from the X pieces of first uplink information N1 pieces of uplink information of the first type are determined; then, the terminal device determines whether to perform multiplexing transmission according to the N1 pieces of first indication information corresponding to the determined N1 pieces of first type of first uplink information. For example, when the values of the N1 pieces of first indication information are all the first preset values, it is determined that multiplexing transmission can be performed; otherwise, it is determined that multiplexing transmission cannot be performed.

Optionally, in an embodiment of the present application, the terminal device first determines, according to the type priority, that N2 pieces of first uplink information of the first type are among the N pieces of first uplink information, and N2 is less than or equal to N; and then, The terminal device uses a method similar to that in Example 1, using part or all of the first indication information in N2 to perform multiplexing and transmission judgment. The last received first indication information in the first DCI performs multiplexing and transmission judgment, or, as shown in 1.1.2, the terminal device may, according to the N2 pieces of first indication information corresponding to the N2 pieces of uplink information of the first type, Determines whether to multiplex transmission.

Example 2: The priorities of the first uplink channel and the second channel are not distinguished, but it is determined whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information according to the indication information included in the DCI.

Understandably, the following 2.1-2.3 are descriptions of different implementations listed in Example 2 according to different sources of uplink information.

2.1. For the case where part or all of the uplink information carried by one uplink channel is scheduled by DCI, and all the uplink information carried by another uplink channel is configured by high-level parameters.

Wherein, part or all of the uplink information carried by one uplink channel is scheduled by DCI, and the case where all the uplink information carried by another uplink channel is configured by high-level parameters may include the following methods. It should be understood that the following methods are described by taking as an example that part or all of the uplink information carried by the first uplink channel is scheduled by DCI, and all the uplink information carried by the second uplink channel is configured by high-level parameters, which does not constitute a limitation to the present application.

Optionally, the N pieces of first uplink information are HARQ-ACKs of the N first PDSCHs scheduled by the N first DCIs, and the M pieces of second uplink information are corresponding to the M SPS PDSCHs configured by the M second higher layer parameters. HARQ-ACK and/or M=1 SRs.

Optionally, the N pieces of first uplink information are HARQ-ACKs of the N first PDSCHs scheduled by the N pieces of first DCI, and the M pieces of second uplink information are configured through a second higher layer parameter (that is, M=1). Data carried by CG PUSCH.

When all the uplink information carried by the second uplink channel is configured by high-level parameters, and some or all of the N pieces of first uplink information carried by the first uplink channel are scheduled by the first DCI, the terminal device determines Whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information can be determined according to the first indication information included in the first DCI of the scheduled first uplink information. For details, see 1.1 According to the first The description of whether the indication information determines whether to perform multiplexing transmission will not be repeated.

When all the uplink information carried by the first uplink channel is configured by high-level parameters, and some or all of the N pieces of second uplink information carried by the second uplink channel are scheduled by the second DCI, then determine whether to The implementation manner of multiplexing and transmitting the N pieces of first uplink information and the M pieces of second uplink information is as follows:

For example, Z pieces of second uplink information in the M pieces of second uplink information are scheduled through Z pieces of second DCI, wherein each second DCI includes a piece of second indication information; Part or all of the second indication information in the Z pieces of second indication information respectively included in the DCI determines whether to multiplex and transmit the N pieces of first uplink information and M pieces of second uplink information, where Z is less than or equal to M.

Wherein, the terminal device determines whether to multiplex and transmit N pieces of first uplink information and M pieces of second uplink information according to some or all of the second indication information in the Z pieces of second indication information, please refer to 1.1. The implementation methods in 1 and 1.1.2 will not be repeated.

It can be seen that, because the method of uplink information configured by the first high-level parameter is relatively fixed, while the method of scheduling uplink information by the second DCI is relatively flexible, although the priority of the first uplink channel is higher than that of the second uplink channel at this time However, whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information is simply determined based on the N pieces of first indication information, which may result in inaccurate determination results. At this time, whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information is determined according to the second indication information, which can improve the accuracy.

2.2. For the case where the uplink information carried by the two uplink channels has the uplink information scheduled by the DCI.

Exemplarily, when the L pieces of first uplink information in the N pieces of first uplink information are scheduled by the L pieces of first downlink control information, and the R pieces of second uplink information in the M pieces of second uplink information are When scheduled through the R second downlink control information, where L and R are both integers greater than or equal to 1, L is less than or equal to N, and R is less than or equal to M, the terminal device can Part or all of the control information and the R pieces of second downlink control information is used to determine whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information.

Exemplarily, the terminal device may determine whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information according to the third indication information included in the fifth downlink control information; wherein the The fifth downlink control information is the last downlink control information received by the terminal device in the L pieces of first downlink control information and the R pieces of second downlink control information, when the fifth downlink control information is the L pieces of first downlink control information When the last received downlink control information in the R, the third indication information is a first indication information or when the fifth downlink control information is the last received downlink control information in the R second downlink control information, the three The indication information is a second indication information.

Exemplarily, the terminal device may determine whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information according to the L pieces of first indication information and the R pieces of second indication information. For example, when the L pieces of first indication information included in the L pieces of first downlink control information and the R pieces of second indication information included in the R pieces of first downlink control information have the same value (or the same value and are the first preset value), the terminal device determines to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information; otherwise, the terminal device determines that the N pieces of first uplink information cannot be multiplexed and transmitted. The information is multiplexed and transmitted with the M pieces of second uplink information.

Exemplarily, the terminal device does not expect the L pieces of first indication information and the R pieces of second indication information to have different values, and determines whether to use the N pieces of first indication information and the R pieces of second indication information according to the L pieces of first indication information and the R pieces of second indication information. Multiplexing and transmitting the pieces of first uplink information and the M pieces of second uplink information is equivalent to determining whether to transmit the N pieces of first indication information according to any one of the L pieces of first indication information and the R pieces of second indication information The pieces of first uplink information and the M pieces of second uplink information are multiplexed and transmitted, as long as the value of the first indication information is the first preset value, it is determined that the N pieces of first uplink information and the M pieces of The second uplink information is multiplexed and transmitted.

2.3. For the case where all the uplink information carried by the two uplink channels is configured by high-level parameters.

The terminal device may determine whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information according to the N pieces of first indication information and the M pieces of second indication information. When the values of the first indication information and the M pieces of second indication information are the same (or the values are the same and both are the first preset values), the terminal device determines to associate the N pieces of first uplink information with the M pieces of The second uplink information is multiplexed and transmitted; otherwise, the terminal device determines that the N pieces of first uplink information and the M pieces of second uplink information cannot be multiplexed and transmitted.

In another embodiment of the present application, since whether it is the N pieces of first uplink information or the M pieces of second uplink information, there may be multiple types of information. At this time, the terminal device can determine the first type of uplink information according to the type priority of the uplink information preconfigured by the network device; , and it is preferentially determined whether to perform multiplexing transmission according to the indication information included in the DCI.

This embodiment can have different combinations with different situations in Example 2. For example, there are several combinations as follows. The so-called combination is the combination of this embodiment and Example 2 in the execution order.

Optionally, in an implementation manner, the terminal device may first determine according to Example 2 that it needs to determine whether multiplexing transmission can be performed according to L2 first indication information and/or R2 second indication information, where L2 is greater than or equal to zero, and R2 is greater than or equal to zero. equal to zero, and L2 and R2 cannot be zero at the same time; then, according to the type priority, from the L2 first uplink information corresponding to the L2 first indication information and/or the R2 second uplink information corresponding to the R2 second indication information One or more pieces of uplink information of the first type are determined, and according to the indication information corresponding to the one or more pieces of uplink information of the first type, it is determined whether multiplexing transmission is possible.

For example, referring to Example 2.1, the uplink information carried by the first uplink channel is all configured by high-layer parameters, and the Z second uplink information among the M second uplink information carried by the second uplink channel is scheduled through Z second DCIs For example, it is determined that L2=0 and R2>0, where the R2 second indication information is the second indication information included in the Z second DCIs. Then, the terminal device determines R3 pieces of second uplink information of the first type from the second uplink information corresponding to the R2 pieces of second indication information, and when the second indication information corresponding to the R3 pieces of second uplink information of the first type is taken When the values are both the first preset values, it is determined that the N pieces of first uplink information and the M pieces of second uplink information can be multiplexed and transmitted.

For another example, referring to Example 2.2, it is determined to obtain L2=L and R2=R, wherein the L2 first indication information is the first indication information included in the above L first DCIs, and the R2 second indication information is the above R second indication information The second indication information included in the DCI. Then, the terminal device determines L3 pieces of first uplink information of the first type and R3 pieces of first uplink information of the first type from the first uplink information corresponding to the L2 pieces of first indication information and the second uplink information corresponding to the R2 pieces of second indication information Two uplink information, when the first indication information corresponding to the L3 first type of first uplink information is the first preset value, and the R3 first type of second uplink information corresponding to the second When the values of the indication information are all the first preset values, it is determined that the N pieces of first uplink information and the M pieces of second uplink information can be multiplexed and transmitted.

Multiplexed transmission, the determination method is similar to the determination method in Example 1; and/or

When the N pieces of first uplink information do not include the first type of uplink information, the terminal device then determines whether multiplex transmission can be performed according to the M4 pieces of second indication information corresponding to the M4 pieces of second type of second uplink information, The determination method is similar to the determination method in Example 1; and/or

Optionally, when the N pieces of first uplink information include N4 pieces of uplink information of the first type and the M pieces of second uplink information include M4 pieces of uplink information of the first type, the terminal device will then use the N4 pieces of uplink information of the first type to The corresponding N4 pieces of first indication information and the M4 pieces of second indication information corresponding to the M4 pieces of second uplink information of the second type are used to determine whether multiplexing transmission is possible. The determination method is similar to the determination method in Example 2. For example, referring to Example 2.2, when N3 pieces of first uplink information include L4 pieces of uplink information scheduled by the first DCI and M4 pieces of second uplink information include R4 pieces of uplink information scheduled by the second DCI, the terminal device schedules the L4 pieces of first DCI according to the and the indication information (the first indication information or the second indication information) contained in the last received DCI in the R4 second DCIs to determine whether multiplexing transmission is possible, when the indication information in the last received DCI is the first When it is a preset value, it is determined that multiplexing transmission can be performed; otherwise, it is determined that multiplexing transmission cannot be performed.

Example 3: Determine whether multiplexing transmission is possible according to the first indication information or the second indication information according to the scheduling method of the first uplink channel and the second uplink channel. When the first uplink channel and the second uplink channel both carry The uplink information of the above is all scheduled by DCI or configured by high-level parameters, and further, according to the priority, it is determined whether the multiplexing transmission is possible according to the first indication information or the second indication information.

Understandably, the following 3.1-3.3 are descriptions of different implementations listed in Example 3 according to different sources of uplink information.

3.1. For the case where part or all of the first uplink information carried by the first uplink channel and part or all of the second uplink information carried by the second uplink channel are both DCI scheduling.

The terminal device first determines the priorities of the first uplink channel and the second uplink channel, and determines that the first uplink channel is the high-priority uplink channel; therefore, the terminal device determines the N first indications corresponding to the first uplink channel according to the Part or all of the first indication information indicated by the DCI in the information is used to determine whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information. For details on whether to perform multiplex transmission, see 1.1.1 and 1.1.2, the description will not be repeated.

3.2. For the case where the N pieces of first uplink information carried by the first uplink channel and the M pieces of second uplink information carried by the second uplink channel are both configured by high-level parameters.

The terminal device first determines the priorities of the first uplink channel and the second uplink channel, and determines that the first uplink channel is the high-priority uplink channel; therefore, the terminal device determines the N first indications corresponding to the first uplink channel according to the Some or all of the first indication information in the information is used to determine whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information. The description is repeated.

3.3. For the case where some or all of the N pieces of first uplink information carried by the first uplink channel are scheduled by DCI, and the M pieces of second uplink information carried by the second uplink channel are configured by high-level parameters.

The terminal device may directly determine whether to combine the N pieces of first uplink information with the M pieces of second uplink information directly according to part or all of the first indication information indicated by the DCI in the N pieces of first indication information corresponding to the first uplink channel. The information is multiplexed and transmitted, and the specific implementation of whether to perform multiplex transmission can be found in 1.1.1 and 1.1.2, and the description will not be repeated.

3.4. For the case where the N pieces of first uplink information carried by the first uplink channel are configured by high-level parameters, and part or all of the M pieces of second uplink information carried by the second uplink channel are DCI scheduling.

The terminal device may directly determine whether to combine the N pieces of first uplink information with the M pieces of second uplink information directly according to part or all of the first indication information indicated by the DCI in the M pieces of second indication information corresponding to the second uplink channel. The information is multiplexed and transmitted, and the specific implementation of whether to perform multiplex transmission can be found in 2.1, and the description will not be repeated.

Example 4: Judging whether multiplexed transmission is possible according to N pieces of first indication information and M pieces of second indication information, when N pieces of first indication information and M pieces of second indication information have the same value (or the same value and both is the first preset value), it is determined that the N pieces of first uplink information and the M pieces of second uplink information can be multiplexed and transmitted. When the N pieces of first indication information and the M pieces of second indication information have different values (or at least one value is not the first preset value), it is determined that the N pieces of first uplink information and the M pieces of second indication information cannot be combined. The uplink information is multiplexed and transmitted.

It should also be noted that before the terminal device determines whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information, it also determines whether the timing requirements are met between the first uplink channel and the second uplink channel ( timeline). The so-called meeting the multiplexing sequence requirement refers to whether the terminal device has enough time to transmit the N first uplink information before starting to transmit the one of the first uplink channel and the second uplink channel with the earliest start time. Multiplexing with M pieces of second uplink information on one channel for joint transmission. And this step may occur before or after it is determined whether to multiplex and transmit the N pieces of first uplink information and the M pieces of second uplink information, which is not limited in this application.

Specifically, as shown in FIG. 4 , in the case where the first uplink channel and the second uplink channel are both PUCCHs, for example, the first uplink channel and the second uplink channel are the physical uplink control channel #1 ( PUCCH#1) and physical uplink control channel #2 (PUCCH#2), and a certain uplink transmission in PUCCH#1 and PUCCH#2 carries the HARQ-ACK of PDSCH, then determine the earliest one of the two PUCCHs Whether the time interval between the start symbol and the PDSCH end symbol is greater than or equal to T ₁ , and T ₁ =N ₁ +d _1,1 +1, if so, determine the difference between the first uplink channel and the second uplink channel If not, it is determined that the timeline is not satisfied between the first upstream channel and the second upstream channel. If neither the first uplink channel nor the second uplink channel carries HARQ-ACK, for example, the first uplink channel and the second uplink channel carry SR and CSI, there is no timeline, in other words , by default the first upstream channel and the second upstream channel satisfy the timeline.

Among them, N ₁ is a preset value, which is related to the subcarrier spacing and UE capability, d _1,1 is a preset offset value related to the time domain length and type of PDSCH, and N ₁ +d _1,1 is used to ensure that the UE receives After the PDSCH, there is enough time to generate the HARQ-ACK and complete the preparation for transmission. The additionally introduced 1 symbol is the processing delay specially introduced for multiplexing multiple PUCCHs.
