Description

Channel processing method, device and storage medium

Technical Field

The present application relates to the field of communications, and in particular, to a channel processing method, apparatus, and storage medium.

Background

The channel is an information channel carried by physical resources, and the channel includes an uplink channel and a downlink channel according to different channel transmission directions. Wherein, aiming at the uplink channel, the definition of two levels of physical layer priority is introduced, and the uplink channel of the two levels of physical layer priority comprises: a Low Priority (LP) Physical Uplink Control Channel (PUCCH), a High Priority (HP) PUCCH, a Low Priority Physical Uplink Shared Channel (PUSCH), and a High Priority PUSCH.

When the time domain resources of the uplink channels with different physical layer priorities are overlapped, the terminal discards the uplink channel with low priority and only transmits the uplink channel with high priority. In order to reduce the impact of discarding the uplink channel with low priority, one of the main research directions is that the communication system supports parallel transmission of PUCCH and PUSCH. How to combine parallel transmission of a PUCCH and a PUSCH with time domain resource overlapping processing of an uplink channel to achieve improvement of an uplink channel transmission effect is a problem that needs to be solved at present.

Fig. 1 is a schematic view of an application scenario provided in an embodiment of the present application, and as shown in fig. 1, the embodiment provides a communication system, where the communication system includes a network device 110 and a plurality of terminals 120, where the embodiment takes 3 of the terminals 120 as an example. The terminal 120 sends Uplink Control Information (UCI) or data to the network device through one or more Uplink physical channels. When there is overlap of time domain resources between multiple uplink physical channels (i.e., time domain overlap of multiple uplink physical channels), the terminal 120 needs to select multiple uplink physical channels where time domain resources overlap to solve the time domain resource overlap between the uplink physical channels.

In a system, for example, a 5G New air interface (New Radio) system, two uplink physical channels with different priorities are supported, and for convenience of description, the uplink physical channel is hereinafter referred to as an uplink channel for short. Two different priority upstream channels include: a Low Priority (LP) Physical Uplink Control Channel (PUCCH), a High Priority (HP) PUCCH, a Low Priority Physical Uplink Shared Channel (PUSCH), and a High Priority PUSCH.

A phenomenon of overlapping time domain resources (i.e., overlapping time domain) may occur between different uplink channels (e.g., between different PUCCHs, between different PUSCHs, between a PUCCH and a PUSCH). For an uplink channel with overlapped time domain resources, there are the following processing modes:

the first method is as follows: and when the uplink channels with different priorities are not introduced, processing the uplink channels with overlapped time domain resources in a channel multiplexing mode. Specifically, when time domain resources overlap between different PUCCHs, the terminal multiplexes Uplink Control Information (UCI) or data on the same PUCCH for transmission, that is, transmits UCI or data on different PUCCHs by one of the different PUCCHs with overlapped time domain resources; when the time domain resources of different PUSCHs are overlapped, the terminal multiplexes the UCI or the data on the same PUSCH for transmission; when the time domain resource of the PUCCH is overlapped with the time domain resource of the PUSCH, the terminal multiplexes the UCI or the data on the same PUSCH for transmission without transmitting the PUCCH; when the time domain resources of the PUCCHs are overlapped with the time domain resources of the PUSCH, the terminal processes the time domain resource overlapping of the PUCCHs firstly, then processes the time domain resource overlapping of the PUCCHs and the PUSCH, and multiplexes UCI or data carried by the PUCCH on the PUSCH for transmission.

The second method comprises the following steps: and after the uplink channels with different priorities are introduced, processing the uplink channels with overlapped time domain resources according to the priorities of the uplink channels. Specifically, when the time domain resources of the uplink channels with different priorities are overlapped, the terminal discards the uplink channel with low priority and only transmits the physical channel with high priority; when the uplink channels with the same priority conflict, the terminal multiplexes the channels according to the mode one; when time domain resource overlapping between the same priority and different priorities exists, the terminal processes channel multiplexing between the uplink channels with low priority, processes time domain resource overlapping between the uplink channels with different priorities, processes channel multiplexing between the uplink channels with high priority, and processes time domain resource overlapping between the uplink channels with high priority and the uplink channels with low priority.

The time domain resource overlapping between the uplink channels refers to time domain resource overlapping between the uplink channels in the same carrier group. For example, in a Dual Connection (DC), a Master Cell Group (MCG, or Primary Cell Group (PCG), or Main Cell Group (MCG) and a Secondary Cell Group (SCG) are respectively in different carrier groups, and when a PUCCH is transmitted on the DC, a Primary PUCCH Group (Primary PUCCH Group) and a Secondary PUCCH Group (Secondary PUCCH Group) may occur, where each PUCCH Group is a carrier Group, and time domain resource overlapping may occur between different PUCCHs in a carrier Group.

With the development of communication technology, in order to reduce the influence of discarding the low-priority uplink channel and improve the transmission effect of the uplink channel, parallel transmission of the PUCCH and the PUSCH on different frequency bands is one of the main research directions of channel transmission. However, a scheme for combining the parallel transmission of the PUCCH and the PUSCH with the time domain resource processing procedure of the uplink channel is currently lacking.

In order to solve the foregoing problems, embodiments of the present application provide a channel processing method, apparatus, and storage medium. According to the method and the device, the time domain resource overlapping among the uplink channels is processed according to whether the terminal supports the parallel transmission of the PUCCH and the PUSCH on different frequency bands, and the time domain resource overlapping of the uplink channels is processed by combining whether the terminal supports the parallel transmission of the PUCCH and the PUSCH on different frequency bands, so that the time domain resource overlapping processing effect of the uplink channels is improved, and the transmission effect of the uplink channels is improved.

The method and the device provided by the embodiment of the application are based on the same application concept, and because the principles of solving the problems of the method and the device are similar, the implementation of the device and the method can be mutually referred, and repeated parts are not described again.

Illustratively, the execution subject of each method embodiment of the present application is a terminal or a network device.

Fig. 2 is a flowchart illustrating a channel processing method according to an embodiment of the present application. As shown in fig. 2, the method includes:

s201, determining a plurality of uplink channels of a terminal, wherein time domain resources of the plurality of uplink channels are overlapped.

The uplink channel is a physical channel for transmitting UCI or data sent by the terminal to the network device through an air interface. The overlapping of time domain resources among a plurality of uplink channels means that time domain resources overlap occurs between each uplink channel and the remaining one or more uplink channels among the plurality of uplink channels.

In this step, configuration information and/or indication information of a plurality of uplink channels on the terminal may be obtained, where the configuration information and/or indication information of the uplink channels includes a frequency band where the uplink channel is located, a time domain resource of the uplink channel, and may further include a carrier where the uplink channel is located, where one frequency band may include a plurality of carriers, and the time domain resource of the uplink channel includes, for example, a start time, an end time, and a duration time of the uplink channel. Therefore, a plurality of uplink channels with overlapped time domain resources can be determined according to the configuration information of the plurality of uplink channels on the terminal.

S202, according to the parallel transmission capability of the terminal, overlapping time domain resources among a plurality of uplink channels is processed.

The parallel transmission capability is used for indicating whether the terminal supports parallel transmission of PUCCH and PUSCH on different frequency bands. The terminal starts the parallel transmission capability, that is, the terminal supports the parallel transmission of the PUCCH and the PUSCH on different frequency bands. The terminal does not start the parallel transmission capability, that is, the terminal does not support the parallel transmission of the PUCCH and the PUSCH on different frequency bands.

In this step, different processing modes are adopted for overlapping the time domain resources between the plurality of uplink channels according to whether the terminal starts the parallel transmission capability, so as to solve the problem of time domain resource conflict between the plurality of uplink channels, and when the terminal starts the parallel transmission capability, the parallel transmission capability of the terminal is utilized, so that the processing effect of overlapping the time domain resources between the plurality of uplink channels is improved.

Specifically, if the terminal starts the parallel transmission capability, that is, the terminal supports parallel transmission of the PUCCH and the PUSCH in different frequency bands, for the PUCCH and the PUSCH in the multiple uplink channels, which are overlapped by time domain resources and located in different frequency bands, it may be determined that the PUCCH and the PUSCH can be transmitted in parallel, channel multiplexing of the PUCCH and the PUSCH is not required, the PUCCH or the PUSCH is not required to be discarded, and the influence of discarding a channel on communication between the terminal and the network device is reduced.

Specifically, if the terminal does not have parallel transmission capability, that is, the terminal does not support parallel transmission of the PUCCH and the PUSCH in different frequency bands, or the terminal opens the parallel transmission capability but does not support simultaneous transmission of the PUCCH and the PUSCH in the same frequency band, it may be determined that the PUCCH and the PUSCH cannot be transmitted in parallel for the PUCCH and the PUSCH in which time domain resources overlap in multiple uplink channels, and the time domain resources overlap between the PUCCH and the PUSCH may be processed according to priorities of the PUCCH and the PUSCH in combination with a channel multiplexing mode.

In one example, when processing time domain resource overlapping between a PUCCH and a PUSCH which cannot be transmitted in parallel, if the priority of the PUCCH is higher than that of the PUSCH, in the PUCCH, a multiplexing channel of UCI or data on the PUSCH is determined, that is, UCI or data on the PUSCH is transmitted through one PUCCH, and the PUSCH is discarded, wherein the number of the PUCCH is one or more. And if the priority of the PUCCH is lower than or equal to the priority of the PUSCH, determining the UCI on the PUCCH or the multiplexing channel of the data in the PUSCH, and discarding the PUCCH, wherein the number of the PUSCHs is one or more.

In the embodiment of the application, the plurality of uplink channels with overlapped time domain resources are processed by combining whether the terminal starts the parallel transmission capability, so that the application of the parallel transmission of the PUCCH and the PUSCH on different frequency bands in the time domain resource overlapping processing of the uplink channels is realized, the discarded channels in the time domain resource overlapping processing of the uplink channels are reduced, the processing effect of the time domain resource overlapping of the uplink channels is improved, and the communication effect between the terminal and the network equipment is further improved.

In some embodiments, the parallel transmission capability includes at least one of: parallel transmission capability of the same priority channel, parallel transmission capability of different priority channels. The parallel transmission capacity of the same priority channel is used for indicating whether the terminal supports parallel transmission of the PUCCH and the PUSCH with the same priority on different frequency bands, and the parallel transmission capacity of the different priority channels is used for indicating whether the terminal supports parallel transmission of the PUCCH and the PUSCH with different priorities on different frequency bands.

Specifically, the terminal starts the parallel transmission capability of the channels with the same priority, that is, the terminal supports the parallel transmission of the PUCCH and the PUSCH with the same priority on different frequency bands; the terminal does not start the parallel transmission capability of the channels with the same priority, namely the terminal does not support the parallel transmission of the PUCCH and the PUSCH with the same priority on different frequency bands; the terminal starts the parallel transmission capability of channels with different priorities, namely the terminal supports the parallel transmission of PUCCH and PUSCH with different priorities on different frequency bands; the terminal starts the parallel transmission capability of the same priority channel, that is, the terminal does not support the parallel transmission of the PUCCH and the PUSCH with different priorities on different frequency bands.

Therefore, different processing can be respectively performed on the time domain resource overlapping between the uplink channels according to whether the terminal starts the parallel transmission capability of the same priority channel and/or whether the terminal starts the parallel transmission capability of different priority channels, so that the processing effect of the time domain resource overlapping of the uplink channels is further improved. In this embodiment, the following description of the embodiments may be referred to for a specific processing procedure.

In some embodiments, the parallel transmission capability is configured through configuration signaling, wherein the configuration signaling is used for indicating whether the terminal turns on the parallel transmission capability. Therefore, the parallel transmission capability of the terminal can be flexibly configured by configuring the soul so as to meet different service requirements.

Optionally, the terminal receives a configuration signaling from the network device, and configures the parallel transmission of the terminal itself according to the configuration signaling. For example, the configuration signaling indicates that the terminal starts parallel transmission, and then the terminal starts parallel transmission supporting PUCCH and PUSCH on different frequency bands; and the configuration signaling indicates that the terminal does not start the parallel transmission, and the terminal does not start the parallel transmission of the PUCCH and the PUSCH on different frequency bands.

Optionally, the network device generates the configuration signaling according to the service environment where the network device is located, for example, when the network device is located in a service environment with a higher requirement on channel transmission capability, the network device generates the configuration signaling indicating that the terminal starts the parallel transmission capability, and when the network device is located in a service environment with a lower requirement on channel transmission capability, the network device generates the configuration signaling indicating that the terminal does not start the parallel transmission capability.

Optionally, the network device receives a configuration request from the service layer, and generates a configuration signaling according to the configuration request. For example, when the service layer requests the configuration terminal to start the parallel transmission capability, the network device generates a configuration signaling indicating that the terminal starts the parallel transmission capability, and when the service layer requests the configuration terminal not to start the parallel transmission capability, the network device generates a configuration signaling indicating that the terminal does not start the parallel transmission capability.

Optionally, the configuration signaling for configuring the terminal to open the parallel transmission capabilities of the different priority channels and the configuration signaling for configuring the terminal to open the parallel transmission capabilities of the same priority channel are the same signaling or different signaling. The signaling is, for example, radio Resource Control (Radio Resource Control RCC) signaling.

Fig. 3 is a flowchart of a channel processing method according to another embodiment of the present application, where the parallel transmission capability includes parallel transmission capabilities of channels with different priorities. As shown in fig. 3, the method includes:

s301, determining a plurality of uplink channels of the terminal, wherein the plurality of uplink channels comprise a first PUCCH and a second PUSCH which are overlapped in time domain resources and different in priority.

For simplicity, the first PUCCH and the second PUSCH are used to represent the PUCCH and the PUSCH with different priorities. For example, when the first PUCCH is a low-priority PUCCH, the second PUSCH is a high-priority PUSCH; the first PUCCH is a high priority PUSCH, and the second PUSCH is a low priority PUSCH.

For determining the plurality of uplink channels of the terminal, reference may be made to the foregoing embodiments, which are not described again.

S302, whether the first PUCCH and the second PUSCH are located on different frequency bands and whether the terminal starts the parallel transmission capability of channels with different priorities is determined.

When the time domain resource of the first PUCCH overlaps with the time domain resource of the second PUSCH, the time domain resource overlapping of the first PUCCH and the second PUSCH needs to be processed.

In this step, in the process of processing the time domain resource overlapping of the first PUCCH and the second PUSCH, since the parallel transmission capabilities of different priority channels of the terminal are limited to the parallel transmission between the PUCCH and the PUSCH with different priorities on different frequency bands, it may be determined whether the first PUCCH and the second PUSCH are located on different frequency bands according to the frequency band where the first PUCCH is located and the frequency band where the second PUSCH is located, and it is determined whether the terminal starts the parallel transmission capabilities of the different priority channels.

Specifically, if the first PUCCH and the second PUSCH are located on different frequency bands and the terminal turns on parallel transmission capabilities of different priority channels, S303 is performed, otherwise (i.e., if the first PUCCH and the second PUSCH are located on the same frequency band or the terminal does not turn on parallel transmission capabilities of different priority channels), S304 is performed.

And S303, when the time domain resources of the first PUCCH and the second PUSCH are overlapped, determining that the first PUCCH and the second PUSCH are transmitted in parallel.

In this step, when the first PUCCH and the second PUSCH are located in different frequency bands, the priorities of the first PUCCH and the second PUSCH are different, and the terminal starts parallel transmission capabilities with different priorities, the terminal can perform parallel transmission on the first PUCCH and the second PUSCH with overlapping time domain resources.

Therefore, when the time domain resources of the first PUCCH and the second PUSCH are overlapped, the first PUCCH and the second PUSCH are determined to be transmitted in parallel, channel multiplexing of the first PUCCH and the second PUSCH is not needed, the first PUCCH or the second PUSCH is not needed to be discarded, and the influence of the discarded channel on communication between the terminal and the network equipment is reduced.

And S304, when the time domain resources of the first PUCCH and the second PUSCH are overlapped, the time domain resources of the first PUCCH and the second PUSCH are overlapped according to the priority of the first PUCCH, the priority of the second PUSCH and the channel multiplexing mode.

In this step, when the first PUCCH and the second PUSCH are located in the same frequency band, the terminal cannot support parallel transmission of the first PUCCH and the second PUSCH regardless of whether the terminal starts parallel transmission capabilities of channels with different priorities. When the terminal does not start the parallel transmission capability of different priority channels, the terminal cannot support the parallel transmission of the first PUCCH and the second PUSCH no matter whether the first PUCCH and the second PUSCH are located in the same frequency band.

Therefore, if the first PUCCH and the second PUSCH are located on the same frequency band or the terminal does not turn on the parallel transmission capabilities of different priority channels, when processing time domain resources of the first PUCCH and the second PUSCH overlap, a channel with higher priority may be selected for the first PUCCH and the second PUSCH to transmit according to the priority of the first PUCCH and the priority of the second PUSCH, and a channel with lower priority may be dropped.

In the embodiment of the application, when a first PUCCH and a second PUSCH which have overlapped time domain resources and different priorities in a plurality of uplink channels are processed, the channel resources of the first PUCCH and the second PUSCH are overlapped and processed according to whether the first PUCCH and the second PUSCH are located in different frequency bands and whether a terminal starts parallel transmission capability of channels with different priorities. Therefore, the application of parallel transmission of PUCCH and PUSCH with different priorities on different frequency bands in the time domain resource overlapping processing of the uplink channel is realized, channels discarded in the time domain resource overlapping processing of PUCCH and PUSCH with different priorities and different frequency bands are reduced, and the time domain resource overlapping processing effect of the uplink channel is improved.

Fig. 4 is a flowchart of a channel processing method according to another embodiment of the present application, where the parallel transmission capability includes parallel transmission capabilities of channels with the same priority. As shown in fig. 4, the method includes:

s401, determining a plurality of uplink channels of a terminal, wherein the plurality of uplink channels comprise a first PUCCH and a first PUSCH which are overlapped in time domain resources and have the same priority.

For the sake of brevity, the first PUCCH and the first PUSCH are used to represent the PUCCH and the PUSCH having the same priority. For example, when the first PUCCH is a low-priority PUCCH, the first PUSCH is a low-priority PUSCH; the first PUCCH is a high priority PUSCH, and the first PUSCH is a high priority PUSCH.

S402, whether the first PUCCH and the first PUSCH are located on different frequency bands or not and whether the terminal starts the parallel transmission capability of the same priority channel or not are determined.

When the time domain resource of the first PUCCH overlaps with the time domain resource of the first PUSCH, the time domain resource overlapping of the first PUCCH and the first PUSCH needs to be processed.

In this step, in the process of processing the time domain resource overlapping of the first PUCCH and the first PUSCH, since the parallel transmission capability of the same priority channel of the terminal is limited to the parallel transmission between the PUCCH and the PUSCH with the same priority on different frequency bands, it may be determined whether the first PUCCH and the first PUSCH are located on different frequency bands according to the frequency band where the first PUCCH is located and the frequency band where the first PUSCH is located, and it is determined whether the terminal starts the parallel transmission capability of the different priority channels.

Specifically, if the first PUCCH and the first PUSCH are located on different frequency bands and the terminal turns on the parallel transmission capability of the same priority channel, S403 is executed, otherwise (i.e., if the first PUCCH and the first PUSCH are located on the same frequency band or the terminal does not turn on the parallel transmission capability of the same priority channel), S404 is executed.

S403, when the time domain resources of the first PUCCH and the first PUSCH are overlapped, the first PUCCH and the first PUSCH are determined to be transmitted in parallel.

In this step, when the first PUCCH and the first PUSCH are located in different frequency bands, the priority of the first PUCCH and the priority of the first PUSCH are different, and the terminal starts parallel transmission capability with the same priority, the terminal may perform parallel transmission on the first PUCCH and the first PUSCH with overlapping time domain resources.

Therefore, when the time domain resources of the first PUCCH and the first PUSCH are overlapped, the first PUCCH and the first PUSCH are determined to be transmitted in parallel, channel multiplexing of the first PUCCH and the first PUSCH is not needed, the first PUCCH does not need to be discarded, and the influence of the discarded channel on communication between the terminal and the network equipment is reduced.

And S404, when the overlapping of the time domain resources of the first PUCCH and the first PUSCH is processed, the overlapping of the time domain resources of the first PUCCH and the first PUSCH is processed according to the priority of the first PUCCH, the priority of the first PUSCH and the channel multiplexing mode.

In this step, when the first PUCCH and the first PUSCH are located in the same frequency band, the terminal cannot support the parallel transmission of the first PUCCH and the first PUSCH regardless of whether the terminal turns on the parallel transmission capability of the same priority. When the terminal does not start the parallel transmission capability with the same priority, the terminal cannot support the parallel transmission of the first PUCCH and the first PUSCH no matter whether the first PUCCH and the first PUSCH are located in the same frequency band.

Therefore, if the first PUCCH and the first PUSCH are located on the same frequency band or the terminal does not turn on parallel transmission capabilities of different priority channels, when processing time domain resources of the first PUCCH and the first PUSCH overlap, the first PUCCH and the first PUSCH may be channel-multiplexed according to the priority of the first PUCCH and the priority of the first PUSCH.

In an example, since the priority of the first PUCCH is the same as the priority of the first PUSCH, in the first PUSCH, UCI on the first PUCCH or a multiplexing channel of data is determined. Wherein the number of the first PUSCHs is one or more. When the number of the first PUSCHs is 1, determining that the first PUSCHs are UCIs or data multiplexing channels on the first PUCCH; when the number of the first PUSCHs is multiple, one PUSCH is selected from the multiple first PUSCHs and is used as a UCI or a multiplexing channel of data on the first PUCCH. Here, there is no limitation on how to select one PUSCH among the plurality of first PUSCHs.

In the embodiment of the application, when a first PUCCH and a first PUSCH which have overlapped time domain resources and have the same priority in a plurality of uplink channels are processed, the channel resources of the first PUCCH and the first PUSCH are overlapped and processed according to whether the first PUCCH and the first PUSCH are located in different frequency bands and whether a terminal opens parallel transmission capability of a channel with the same priority. Therefore, the application of parallel transmission of the PUCCH and the PUSCH with the same priority on different frequency bands in the time domain resource overlapping processing of the uplink channel is realized, channels discarded in the time domain resource overlapping processing of the PUCCH and the PUSCH with the same priority and different frequency bands are reduced, and the time domain resource overlapping processing effect of the uplink channel is improved.

Fig. 5 is a flowchart illustrating a channel processing method according to another embodiment of the present application. As shown in fig. 5, the method includes:

s501, determining a plurality of uplink channels of the terminal, wherein the plurality of uplink channels comprise a first PUCCH and a first PUSCH with overlapped time domain resources, and the priority of the first PUCCH and the priority of the first PUSCH are low priority.

For the sake of brevity, the first PUCCH and the first PUSCH are used to represent the PUCCH and the PUSCH having the same priority. The priority of the uplink channel may be divided into a low priority and a high priority, and specific reference may be made to the foregoing description of the uplink channel with two different priorities, which is not described again.

For determining the multiple uplink channels of the terminal, reference may be made to the foregoing embodiments, which are not described in detail herein.

S502, determining whether a first PUSCH exists, wherein the time domain resources of the first PUSCH do not overlap with the time domain resources of the high-priority PUSCH on the same carrier wave.

In this step, in the process of processing the overlapping of the time domain resources of the first PUCCH and the first PUSCH, if it is determined that the first PUCCH and the first PUSCH cannot be transmitted in parallel according to the parallel transmission capability of the terminal, it may be determined whether there is a first PUSCH in which the time domain resources are not overlapped with the time domain resources of the high-priority PUSCH on the same carrier in the first PUSCH in which the time domain resources are overlapped with the time domain resources of the first PUCCH. If it is determined that there is a first PUSCH having time domain resources that do not overlap with the time domain resources of the high-priority PUSCH on the same carrier, S503 is performed, otherwise, S504 is performed.

If it is determined that the first PUCCH and the first PUSCH can be transmitted in parallel according to the parallel transmission capability of the terminal, it is determined that the first PUCCH and the first PUSCH are transmitted in parallel when processing time domain resources of the first PUCCH and the first PUSCH overlap, without performing S502, S503, and S504.

In an example, determining that the first PUCCH and the first PUSC cannot be transmitted in parallel according to a parallel transmission capability of the terminal includes at least one of: the terminal does not start the parallel transmission capability; the first PUCCH and the first PUSCH are located on the same frequency band.

In another example, when the parallel transmission capability includes parallel transmission capabilities of different priority channels and a parallel transmission capability of the same priority, determining that the first PUCCH and the first PUSCH cannot be transmitted in parallel according to the parallel transmission capability of the terminal includes at least one of the following: the terminal does not start the parallel transmission capability with the same priority; the terminal starts the parallel transmission capability with the same priority, but the first PUCCH and the first PUSCH are positioned on the same frequency band.

Optionally, determining whether there is a first PUSCH whose time domain resource is not overlapped with the time domain resource of the high-priority PUSCH on the same carrier includes: determining that a high priority PUSCH and a first PUSCH/first PUCCH meet timeline requirements; or, determining whether the end position of Downlink Control Information (DCI) corresponding to the high-priority PUSCH and the start position of the first PUSCH/first PUCCH are greater than a predetermined time. In order to ensure that when the terminal processes the time domain overlapping of the first PUCCH and the first PUSCH, it is determined that there is still an overlapping high priority PUSCH, the network side needs to ensure that the above requirements are met during scheduling, otherwise, the terminal may have different processing results at different times, which affects the terminal implementation.

S503, when the overlapping of the time domain resources of the first PUCCH and the first PUSCH is processed, in the first PUSCH of which the time domain resources are not overlapped with the time domain resources of the high-priority PUSCH on the same carrier wave, determining the UCI on the first PUCCH or the multiplexing channel of the data.

In this step, if there is a first PUSCH in which time domain resources overlap with those of a first PUCCH, and if there is a first PUSCH in which time domain resources do not overlap with those of a high-priority PUSCH on the same carrier, when processing time domain resources overlap between a high-priority PUSCH and a low-priority PUSCH, there is no high-priority PUSCH overlapping with those of the first PUSCH, and the first PUSCH is not discarded because its own priority is low. Therefore, when processing that the time domain resources of the first PUCCH and the first PUSCH overlap, the UCI on the first PUCCH or the multiplexed channel of the data may be determined in the first PUSCH whose time domain resources do not overlap with the time domain resources of the high priority PUSCH on the same carrier. The number of the first PUSCHs of which the time domain resources are not overlapped with the time domain resources of the high-priority PUSCHs on the same carrier wave may be one or more, and if the number of the first PUSCHs is one, the first PUSCHs of which the time domain resources are not overlapped with the time domain resources of the high-priority PUSCHs on the same carrier wave are determined as UCIs or data multiplexing channels on the first PUCCH; and if the number of the PUSCHs is multiple, selecting one PUSCH as a UCI (uplink control information) or data multiplexing channel on the first PUSCH in which the time domain resources are not overlapped with the time domain resources of the high-priority PUSCHs on the same carrier.

S504, when the time domain resources of the first PUCCH and the first PUSCH are overlapped, the first PUCCH and the first PUSCH are reserved.

In this step, in the first PUSCH in which the time domain resources overlap with the time domain resources of the first PUCCH, there is no first PUSCH in which the time domain resources do not overlap with the time domain resources of the high-priority PUSCH on the same carrier, that is, each first PUSCH which overlaps with the time domain resources of the first PUCCH and cannot be transmitted in parallel with the first PUCCH overlaps with the time domain resources of the high-priority PUSCH on the same carrier. Since the priority of the first PUSCH is low priority and the first PUSCH cannot be transmitted in parallel with a high priority PUSCH overlapping with the first PUSCH time domain resource on the same carrier, the first PUSCH will be dropped when processing the time domain resources of the first PUSCH and the high priority PUSCH on the same carrier overlap.

Considering that the first PUSCH is to be dropped when processing the time domain resources of the first PUSCH and the high priority PUSCH on the same carrier overlap, when processing the time domain resources of the first PUCCH and the first PUSCH overlap, the first PUCCH and the first PUSCH are reserved, and channel multiplexing of the first PUCCH and the first PUSCH is not performed, in other words, the first PUSCH is not determined as a multiplexed channel of UCI or data on the first PUCCH, so as to avoid the first PUCCH being dropped.

In the embodiment of the application, when the time domain resources of the low-priority PUCCH and the low-priority PUSCH collide, whether the low-priority PUSCH is discarded in a subsequent process due to the time domain resource collision with the high-priority PUSCH of the same carrier is considered, if so, when the collision between the low-priority PUCCH and the low-priority PUSCH is processed, channel multiplexing between the low-priority PUCCH and the low-priority PUSCH is not performed, so that the low-priority PUCCH is prevented from being discarded, the influence of a discarded channel on uplink channel transmission is reduced, and the processing effect of time domain resource overlapping of an uplink channel is improved.

Fig. 6 is a flowchart illustrating a channel processing method according to another embodiment of the present application. As shown in fig. 6, the method includes:

s601, determining a plurality of uplink channels of the terminal, wherein the plurality of uplink channels comprise a first PUCCH and a first PUSCH with overlapped time domain resources, and the priority of the first PUCCH and the priority of the first PUSCH are low priority.

The implementation principle and the technical effect of S601 may refer to the description of S501, and are not described again.

S602, in a plurality of uplink channels, determining whether a first PUSCH exists, wherein time domain resources of the first PUSCH do not overlap with high-priority PUCCH time domain resources which cannot be transmitted in parallel.

In this step, in the process of processing the overlapping of the time domain resources of the first PUCCH and the first PUSCH, if it is determined that the first PUCCH and the first PUSCH cannot be transmitted in parallel according to the parallel transmission capability of the terminal, it may be determined whether there is a first PUSCH in which the time domain resources are not overlapped with the time domain resources of the high-priority PUCCH that cannot be transmitted in parallel in the first PUSCH in which the time domain resources are overlapped with the time domain resources of the first PUCCH. If it is determined that there is a first PUSCH in which time domain resources do not overlap with time domain resources of a high priority PUCCH that cannot be transmitted in parallel, S603 is performed, otherwise, S604 is performed. The specific situation that the first PUCCH and the first PUSC cannot be transmitted in parallel according to the parallel transmission capability of the terminal may refer to the description in S502, and is not described again.

Wherein if it is determined that the first PUCCH and the first PUSCH can be transmitted in parallel according to the parallel transmission capability of the terminal, when processing that the time domain resources of the first PUCCH and the first PUSCH overlap, it is determined that the first PUCCH and the first PUSCH are transmitted in parallel without performing S502, S503, and S504.

The method comprises the steps of determining whether a first PUSCH (physical uplink shared channel) exists, wherein the first PUSCH can be determined according to the parallel transmission capability of a terminal, and the time domain resource of the first PUSCH is not overlapped with the time domain resource of a high-priority PUCCH (physical uplink control channel) which cannot be transmitted in parallel.

Determining whether a first PUSCH exists, wherein the first PUSCH has time domain resources which are not overlapped with the time domain resources of the high-priority PUCCH which cannot be transmitted in parallel, according to the parallel transmission capability of the terminal, and the determining comprises at least one of the following steps: if the parallel transmission capability of the terminal comprises the parallel transmission capability of channels with different priorities, determining whether a first PUSCH (physical uplink shared channel) with time domain resources not overlapped with the time domain resources of a PUCCH (physical uplink control channel) with high priority on the same frequency band is available; and if the parallel transmission capability of the terminal does not comprise the parallel transmission capability of the channels with different priorities, determining whether the first PUSCH has time domain resources which are not overlapped with the time domain resources of the PUCCH with high priority.

Optionally, the determining whether there is a first PUSCH/first PUCCH whose time domain resource does not overlap with a time domain resource of a high priority PUCCH that cannot be transmitted in parallel includes: determining whether a timeline requirement is met between a high priority PUCCH and a first PUSCH/first PUCCH; or, determining whether the DCI end position corresponding to the high-priority PUCCH and the start position of the first PUSCH/first PUCCH are greater than a predetermined time. In order to ensure that when the terminal processes the time domain overlapping of the first PUCCH and the first PUSCH, it is determined that there is still an overlapping high priority PUSCH, the network side needs to ensure that the above requirements are met during scheduling, otherwise, the terminal may have different processing results at different times, which affects the terminal implementation.

S603, when processing that the time domain resources of the first PUCCH and the first PUSCH overlap, in the first PUSCH where the time domain resources do not overlap with the time domain resources of the high priority PUCCH that cannot be transmitted in parallel, determining the UCI on the first PUCCH or the multiplexing channel of the data.

In this step, if there is a first PUSCH in which time domain resources overlap with those of a first PUCCH, and if there is a first PUSCH in which time domain resources do not overlap with those of a high-priority PUCCH that cannot be transmitted in parallel, when processing time domain resources overlap between a high-priority PUSCH and a low-priority PUSCH, there is no high-priority PUCCH that overlaps with those of the first PUSCH and cannot be transmitted in parallel with the first PUSCH, and the first PUSCH is not discarded because its own priority is low. Therefore, when processing that the time domain resources of the first PUCCH and the first PUSCH overlap, the UCI on the first PUCCH or the multiplexed channel of the data may be determined in the first PUSCH whose time domain resources do not overlap with the time domain resources of the high priority PUSCH on the same carrier.

The number of the first PUSCHs of which the time domain resources are not overlapped with the time domain resources of the high-priority PUSCHs on the same carrier wave may be one or more, and if the number of the first PUSCHs is one, the first PUSCHs of which the time domain resources are not overlapped with the time domain resources of the high-priority PUSCHs on the same carrier wave are determined as UCIs or data multiplexing channels on the first PUCCH; and if the number of the PUSCHs is multiple, selecting one PUSCH as a UCI (uplink control information) or data multiplexing channel on the first PUSCH in which the time domain resources are not overlapped with the time domain resources of the high-priority PUSCHs on the same carrier.

S604, when the time domain resources of the first PUCCH and the first PUSCH are overlapped, the first PUCCH and the first PUSCH are reserved.

In this step, in the first PUSCH in which the time domain resources overlap with the time domain resources of the first PUCCH, there is no first PUSCH in which the time domain resources do not overlap with the time domain resources of the high priority PUCCH that cannot be transmitted in parallel, that is, each first PUSCH that overlaps with the time domain resources of the first PUCCH and cannot be transmitted in parallel with the first PUCCH overlaps with the time domain resources of the high priority PUCCH that cannot be transmitted in parallel. Since the priority of the first PUSCH is low priority, and there is a high priority PUCCH whose time domain resource overlaps with the first PUSCH time domain resource and cannot be transmitted in parallel with the first PUSCH, the first PUSCH is discarded when the time domain resources of processing the first PUSCH and the high priority PUCCH overlap.

Considering that the first PUSCH is to be dropped when processing the time domain resources of the first PUCCH and the high priority PUCCH overlap, when processing the time domain resources of the first PUCCH and the first PUSCH overlap, the first PUCCH and the first PUSCH are reserved, and channel multiplexing of the first PUCCH and the first PUSCH is not performed, in other words, the first PUSCH is not determined as a multiplexing channel of UCI or data on the first PUCCH, so as to avoid the first PUCCH being dropped.

In the embodiment of the application, when the time domain resources of the low-priority PUCCH and the low-priority PUSCH collide, whether the low-priority PUSCH is discarded in a subsequent process due to the time domain resource collision with the high-priority PUCCH which cannot be transmitted in parallel is considered, if yes, when the collision between the low-priority PUCCH and the low-priority PUSCH is processed, channel multiplexing between the low-priority PUCCH and the low-priority PUSCH is not performed, so that the low-priority PUCCH is prevented from being discarded, the influence of a discarded channel on uplink channel transmission is reduced, and the processing effect of time domain resource overlapping of uplink channels is improved.

Fig. 7 is a flowchart illustrating a channel processing method according to another embodiment of the present application. As shown in fig. 7, the method includes:

s701, determining a plurality of uplink channels of the terminal, wherein the plurality of uplink channels comprise a first PUCCH and a second PUSCH with overlapped time domain resources, the priority of the first PUCCH is high priority, and the priority of the second PUSCH is low priority.

For simplicity of description, the first PUCCH and the second PUSCH have different priorities, in this embodiment, the priority of the first PUCCH is a high priority, and the priority of the second PUSCH is a low priority.

S702, under the condition that the first PUCCH and the second PUSCH cannot be transmitted in parallel, whether a high-priority PUSCH with time domain resources overlapped with the first PUCCH exists in a plurality of uplink channels or not is determined.

In this step, when the first PUCCH and the second PUSCH cannot be transmitted in parallel, the time domain resources of the first PUCCH and the second PUSCH need to be overlapped for processing. Wherein, it is determined that the first PUCCH and the second PUSCH cannot be transmitted in parallel, the determination may be performed based on the parallel transmission capability of the terminal, for example: the terminal does not start the parallel transmission capability; or the terminal starts the parallel transmission capability of the channels with the same priority; or the terminal starts the parallel transmission capability of different priority channels, but the first PUCCH and the second PUSCH are positioned on the same frequency band.

In this step, when overlapping the time domain resources of the first PUCCH and the second PUSCH is processed, it may be determined whether a high-priority PUSCH in which the time domain resources overlap the first PUCCH exists in a plurality of uplink channels, and if so, S703 is executed, otherwise, S704 is executed.

Optionally, the determining whether there is a high-priority PUSCH with time domain resources overlapping with the first PUCCH includes: determining whether a timeline requirement is met between a high priority PUSCH and a first PUCCH; or, determining whether the end position of the DCI corresponding to the high-priority PUSCH and the start position of the first PUCCH are greater than a predetermined time.

And S703, reserving the first PUCCH and the second PUSCH when the overlapping of the time domain resources of the first PUCCH and the second PUSCH is processed.

In this step, in a plurality of uplink channels of the terminal, there is a high-priority PUSCH in which time domain resources overlap with those of the first PUCCH, that is, there is a high-priority PUSCH which cannot be transmitted in parallel with the first PUCCH. When the time domain resources of the first PUCCH and the PUSCH with high priority are processed to be overlapped, the priority of the first PUCCH is also high, when the time domain resources of the PUCCH with the same priority are overlapped with the time domain resources of the PUSCH, the UCI or the multiplexing channel of the data on the PUCCH is determined, and the PUCCH is discarded.

Therefore, when the time domain resources of the first PUCCH and the second PUSCH are overlapped, although the priority of the first PUCCH is higher than that of the second PUSCH, considering that the first PUCCH is discarded when the time domain resources of the first PUCCH and the high priority PUSCH are overlapped, the first PUCCH and the second PUSCH can be reserved when the time domain resources of the first PUCCH and the second PUSCH are overlapped, the second PUSCH is prevented from being discarded, and the discarded low priority channel is reduced.

S704, when the time domain resources of the first PUCCH and the second PUSCH are overlapped, the first PUCCH is reserved, and the second PUSCH is discarded.

In this step, there is no high-priority PUSCH in which the time domain resource overlaps with the time domain resource of the first PUCCH in the plurality of uplink channels of the terminal, and at this time, the first PUCCH is not discarded due to the presence of the high-priority PUSCH in which the time domain resource collides. Therefore, when processing time domain resources of the first PUCCH and the second PUSCH overlap, since the second PUSCH has a lower priority than the first PUCCH, the second PUSCH of low priority may be dropped and the first PUCCH of high priority may be retained.

In the embodiment of the application, when the time domain resources of the high-priority PUCCH and the low-priority PUSCH collide, whether the high-priority PUCCH is discarded in a subsequent process due to the existence of the high-priority PUSCH incapable of being transmitted in parallel is considered, and if so, the low-priority PUSCH is not discarded when the collision of the high-priority PUCCH and the low-priority PUSCH is processed, so that the influence of a discarded channel on uplink channel transmission is reduced, and the processing effect of time domain resource overlapping of the uplink channel is improved.

Fig. 8 is a flowchart illustrating a channel processing method according to another embodiment of the present application. As shown in fig. 8, the method includes:

s801, determining a plurality of uplink channels of a terminal, wherein the plurality of uplink channels comprise a first PUCCH and a second PUCCH with overlapped time domain resources, the priority of the first PUCCH is low priority, and the priority of the second PUCCH is high priority.

For the sake of brevity, the first PUCCH and the second PUCCH having different priorities are represented by the first PUCCH and the second PUCCH, in this embodiment, the priority of the first PUCCH is a low priority, and the priority of the second PUCCH is a high priority.

S802, in a plurality of uplink channels, determining whether a PUSCH with time domain resources overlapping with a second PUCCH and high priority exists.

In this step, when overlapping the time domain resources of the first PUCCH and the second PUCCH is processed, it may be determined whether a high-priority PUSCH in which the time domain resources overlap the second PUCCH exists in the multiple uplink channels, and if so, S803 is executed, otherwise, S804 is executed.

Optionally, determining whether there is a PUSCH with a high priority and time domain resources overlapping with the second PUCCH includes: determining whether a timeline requirement is met between a high priority PUSCH and a second PUCCH; or, determining whether the end position of the DCI corresponding to the high-priority PUSCH and the start position of the second PUCCH are greater than a predetermined time.

And S803, reserving the first PUCCH and the second PUCCH when the overlapping of the time domain resources of the first PUCCH and the second PUCCH is processed.

In this step, in the plurality of uplink channels, there is a PUSCH having a high priority and having time domain resources overlapping with the time domain resources of the second PUCCH, that is, there is a PUSCH having a high priority and being incapable of being transmitted in parallel with the second PUCCH. When the time domain resources of the second PUCCH and the PUSCH with high priority are overlapped, the priority of the second PUCCH is also high, when the time domain resources of the PUCCH with the same priority and the PUSCH are overlapped, the UCI or the multiplexing channel of the data on the PUCCH is determined, and the PUCCH is discarded.

Therefore, when processing the time domain resources of the first PUCCH and the second PUCCH overlapping, although the priority of the second PUCCH is higher than that of the first PUCCH, considering that the second PUCCH will be discarded when processing the time domain resources of the second PUCCH and the high priority PUSCH overlapping, when processing the time domain resources of the first PUCCH and the second PUCCH overlapping, the first PUCCH and the second PUCCH may be reserved, the first PUSCH is prevented from being discarded, and the discarded low priority channel is reduced.

S804, when the overlapping of the time domain resources of the first PUCCH and the second PUCCH is processed, the second PUCCH is reserved, and the first PUCCH is discarded.

In this step, there is no PUSCH having a high priority whose time domain resource overlaps with the time domain resource of the second PUCCH in the plurality of uplink channels, and at this time, the second PUCCH is not discarded due to the presence of the high priority PUSCH whose time domain resource conflicts. Therefore, when processing time domain resources of the first PUCCH and the second PUCCH overlap, since the first PUCCH has a lower priority than the second PUCCH, the first PUCCH having a low priority may be discarded and the second PUCCH having a high priority may be reserved.

In the embodiment of the application, when the time domain resources of the high-priority PUCCH and the low-priority PUCCH collide, whether the high-priority PUCCH is discarded in the subsequent process due to the existence of the high-priority PUSCH incapable of being transmitted in parallel is considered, and if yes, the low-priority PUCCH is not discarded when the high-priority PUCCH and the low-priority PUCCH collide, so that the influence of a discarded channel on uplink channel transmission is reduced, and the processing effect of time domain resource overlapping of uplink channels is improved.

Generally, a processing procedure of overlapping time domain resources of an uplink channel is sequentially divided into the following steps:

the method comprises the following steps: processing time domain resource overlap between low priority channels; step two: processing time domain resource overlapping between a high-priority channel and a low-priority channel before multiplexing; step three: processing time domain resource overlap between high priority channels; step four: and processing time domain resource overlapping between the multiplexed high-priority channel and the multiplexed low-priority channel. The low-priority channel is a low-priority uplink channel, and the high-priority channel is a high-priority uplink channel.

One or more of the first step, the second step, the third step and the fourth step may be performed according to whether the multiple uplink channels have time domain resource overlapping between low priority channels, time domain resource overlapping between different priority channels and time domain resource overlapping between high priority channels. The following describes, by way of example, a combination of the parallel processing capability of the terminal and the above steps, specifically as follows:

fig. 9 is a flowchart illustrating a channel processing method according to another embodiment of the present application, based on the parallel transmission capability of the terminal to open channels with different priorities. As shown in fig. 9, the method includes:

s901, processing time domain resource overlapping among low priority channels in a plurality of uplink channels.

In this step, the time domain resource overlapping between the PUCCH with low priority is processed first, then the time domain resource overlapping between the PUCCH with low priority and the PUSCH with low priority is processed, and then the time domain resource overlapping between the PUSCHs with low priority is processed. In this step, the time domain resource overlapping between the low priority channels may be performed in a channel multiplexing manner, which may specifically refer to the description of the foregoing embodiment and will not be described herein again.

Optionally, when processing the time domain resources of the PUCCH with low priority and the PUSCH with low priority are overlapped, it is determined whether there is a PUSCH with low priority in the multiple uplink channels where the time domain resources are overlapped with the time domain resources of the PUCCH and the time domain resources are not overlapped with the PUSCH with high priority on the same carrier. If so, multiplexing the low-priority PUCCH to the low-priority PUSCH, and discarding the low-priority PUCCH. If not, the low-priority PUCCH and the low-priority PUSCH are not multiplexed.

S902, according to the parallel transmission capacity of different priority channels started by the terminal, the time domain resource overlapping between a high priority channel and a low priority channel before multiplexing in a plurality of uplink channels is processed.

The high-priority channel before multiplexing refers to a high-priority channel on which time domain resource overlapping processing between the high-priority channels has not been performed.

In this step, when processing time domain resources of a high-priority PUCCH and a low-priority PUSCH in multiple uplink channels overlapping, whether the high-priority PUCCH and the low-priority PUSCH can be transmitted in parallel is determined according to parallel transmission capabilities of different priority channels started by a terminal, if yes, the high-priority PUCCH and the low-priority PUSCH are determined to be transmitted in parallel, otherwise, the low-priority PUSCH is discarded, and the high-priority PUCCH is retained.

When the time domain resources of the high-priority PUSCHs and the low-priority PUCCHs in the plurality of uplink channels are overlapped, whether the high-priority PUSCHs and the low-priority PUCCHs can be transmitted in parallel or not is judged according to the parallel transmission capability of different priority channels started by the terminal, if so, the high-priority PUSCHs and the low-priority PUCCHs are determined to be transmitted in parallel, otherwise, the low-priority PUCCHs are discarded, and the high-priority PUSCHs are reserved.

And S903, processing time domain resource overlapping among high-priority channels in a plurality of uplink channels.

In this step, the time domain resource overlapping between the high-priority PUCCH is processed first, then the time domain resource overlapping between the high-priority PUCCH and the high-priority PUSCH is processed, and then the time domain resource overlapping between the high-priority PUSCH is processed. In this step, the time domain resource overlapping between the high priority channels may be performed in a channel multiplexing manner, which may specifically refer to the description of the foregoing embodiment and is not described herein again.

And S904, processing time domain resource overlapping between a high priority channel and a low priority channel multiplexed in a plurality of uplink channels according to the parallel transmission capacity of different priority channels started by the terminal.

The multiplexed high-priority channel refers to a high-priority channel after the time domain resource overlapping processing between the high-priority channels is completed.

In this step, when overlapping time domain resources of different priority channels in a plurality of uplink channels is processed, according to the parallel transmission capability of different priority channels started by the terminal, it is determined whether the different priority channels with overlapped time domain resources can be transmitted in parallel, if so, it is determined that the different priority channels with overlapped time domain resources are transmitted in parallel, otherwise, a low priority channel in the different priority channels with overlapped time domain resources is discarded. Specifically, reference may be made to the description of S902, which is not repeated.

As an example, fig. 10 is a first diagram illustrating time domain resource overlapping among multiple uplink channels. As shown in fig. 10, CC1 and CC2 are two carriers on different frequency bands, and the terminal supports parallel transmission of PUCCH and PUSCH with different priorities on the two carriers. Here, the CC1 has LP PUCCH (low priority PUCCH), and the CC2 has LP PUSCH (low priority PUSCH) and LP PUSCH (low priority PUSCH).

When processing time domain resource overlapping of multiple uplink channels shown in fig. 10, if LP PUCCH, LP PUSCH, and HP PUSCH on CC1 and CC2 all satisfy timeline requirements, the terminal knows that there is an HP PUSCH on the same carrier as the LP PUSCH and overlapping with the LP PUSCH time domain resource, that is, it knows that there is an HP PUSCH overlapping with the LP PUSCH time domain resource on CC2 when processing time domain resource overlapping of LP PUCCH and LP PUSCH on CC 1. At this time, the terminal does not multiplex the LP PUCCH on CC1 and the LP PUSCH on CC 2. And when the terminal processes the time domain resource overlapping between the LP PUSCH and the HP PUSCH, the LP PUSCH is discarded. Thus, the final processing result is that the terminal transmits LP PUCCH on CC1 and HP PUSCH on CC 2.

If the LP PUCCH, LP PUSCH and HP PUSCH on CC1 and CC2 do not meet the timeline requirements, the terminal does not know that there is an HP PUSCH on the same carrier as the LP PUSCH and overlapping with the LP PUSCH time domain resource when processing that the LP PUCCH on CC1 overlaps with the time domain resource of the LP PUSCH. At this time, the terminal multiplexes the LP PUCCH on CC1 and the LP PUSCH on CC2, and discards the LP PUCCH. And when the terminal processes the time domain resource overlap between the LP PUSCH and the HP PUSCH, discarding the LP PUSCH. Thus, the final processing result is that the terminal transmits the HP PUSCH on CC 2.

In some embodiments, one possible implementation of S902 includes: when the overlapping of the time domain resources of the low-priority PUCCH and the high-priority PUCCH in a plurality of uplink channels is processed, judging whether a high-priority PUSCH with the time domain resources overlapping with the time domain resources of the high-priority PUCCH exists or not, and if the high-priority PUSCH exists, not discarding the low-priority PUCCH; and/or when the time domain resources of the low-priority PUSCHs and the high-priority PUCCHs in the plurality of uplink channels are overlapped, judging whether the high-priority PUSCHs with the time domain resources overlapped with the time domain resources of the high-priority PUCCHs exist or not, and if the high-priority PUSCHs exist, not discarding the low-priority PUSCHs.

When there is a high-priority PUSCH in which time domain resources overlap with those of the high-priority PUCCH, the high-priority PUCCH is multiplexed to the time domain resources and the high-priority PUSCH when the time domain resources between the high-priority channels overlap.

Optionally, if the terminal further starts the parallel transmission of the PUCCH and the PUSCH with the same priority, a possible implementation manner of determining whether there is a high-priority PUSCH in which the time domain resource overlaps with the time domain resource of the high-priority PUCCH includes: and judging whether a high-priority PUSCH with the same frequency band as the high-priority PUCCH and overlapped time domain resources with the high-priority PUCCH exists or not.

As an example, fig. 11 is a second exemplary diagram of time domain resource overlapping among multiple uplink channels. As shown in fig. 11, CC1 and CC2 are two carriers on different frequency bands, and the terminal supports parallel transmission of PUCCH and PUSCH with different priorities on the two carriers. The CC1 is provided with an LP PUCCH and an HP PUCCH overlapped with the LP PUCCH, and the CC2 is provided with an HP PUSCH.

When processing time domain resource overlapping of multiple uplink channels shown in fig. 11, if LP PUCCH, HP PUCCH, and HP PUSCH on CC1 and CC2 all satisfy timeline requirements, the terminal knows that there is time domain resource overlapping of HP PUCCH and HP PUSCH on the same carrier as LP PUCCH when processing time domain resource overlapping of LP PUCCH and HP PUCCH on CC1, that is, knows that there is HP PUSCH overlapping of HP PUCCH on CC1 on CC2 and HP PUCCH on CC1 overlaps of LP PUCCH on CC 1. At this time, the terminal pair does not discard the LP PUCCH on CC 1. The terminal discards the HP PUCCH when processing time domain resource overlap between the HP PUCCH on CC1 and the HP PUSCH on CC 2. Thus, the final processing result is that the terminal transmits LP PUCCH on CC1 and HP PUSCH on CC 2.

If the LP PUCCH, the HP PUCCH and the HP PUSCH on the CC1 and the CC2 do not meet the timeline requirements, when the terminal processes the time domain resources of the LP PUCCH and the HP PUCCH on the CC1 to overlap, the terminal does not know that the time domain resources of the HP PUCCH and the time domain resources of the HP PUSCH on the same carrier with the LP PUCCH overlap. At this time, the terminal discards the LP PUCCH on CC 1. And when the terminal processes the time domain resource overlapping between the HP PUCCH and the HP PUSCH, discarding the HP PUCCH. Thus, the final processing result is that the terminal transmits the HP PUSCH on CC 2.

In some embodiments, if the terminal turns on the parallel transmission capability of the same priority channel, one possible implementation manner of S901 includes: when the time domain resources of a low-priority PUCCH and a low-priority PUSCH in a plurality of uplink channels are overlapped, judging whether the low-priority PUSCH which cannot be transmitted in parallel with the low-priority PUCCH exists or not; if the uplink channel exists, in the low-priority PUSCH which cannot be transmitted in parallel with the low-priority PUCCH, the UCI on the low-priority PUCCH or the multiplexing channel of the data is determined. That is, the low-priority PUCCH is not multiplexed to the low-priority PUSCH that can be transmitted in parallel with the low-priority PUCCH.

At this time, one possible implementation manner of S903 includes: when the time domain resources of a high-priority PUCCH and a high-priority PUSCH in a plurality of uplink channels are overlapped, judging whether the high-priority PUSCH which cannot be transmitted in parallel with the high-priority PUCCH exists or not; if the uplink channel exists, in a high-priority PUSCH which cannot be transmitted in parallel with the high-priority PUCCH, the UCI on the high-priority PUCCH or the multiplexing channel of data is determined. That is, the high-priority PUCCH is not multiplexed to the high-priority PUSCH that can be transmitted in parallel with the high-priority PUCCH.

As an example, fig. 12 is a third exemplary diagram of time domain resource overlapping among multiple uplink channels. As shown in fig. 12, CC1 and CC2 are two carriers on the same frequency band, CC3 is a carrier located on a different frequency band from CC1 and CC2, and the terminal supports parallel transmission of PUCCH and PUSCH on CC1 and CC 3. Wherein, one HP PUCCH on CC1 is respectively overlapped with LP PUSCH on CC1, LP PUSCH on CC2 and LP PUSCH on CC3, and one HP PUCCH on CC1 is overlapped with HP PUSCH on CC 3.

When the time domain resources of the plurality of uplink channels shown in fig. 12 are overlapped, in S901, the LP PUCCH on CC1 and the LP PUSCH on CC1 cannot be transmitted in parallel, and the LP PUCCH on CC1 and the LP PUSCH on CC2 cannot be transmitted in parallel, but the LP PUCCH on CC1 and the LP PUSCH on CC3 can be transmitted in parallel. Therefore, LP PUCCH on CC1 is multiplexed on LP PUSCH on CC1 or CC 2. In S903, the HP PUCCH on CC1 and the HP PUSCH on CC3 may be transmitted in parallel.

In some embodiments, if the terminal turns on the parallel transmission capability of the same priority channel, another possible implementation manner of S901 includes: when processing the time domain resource overlapping of the low-priority PUCCH and the low-priority PUSCH which cannot be transmitted in parallel in a plurality of uplink channels, judging whether the low-priority PUSCH which cannot be transmitted in parallel with the low-priority PUCCH and cannot be transmitted in parallel with the high-priority PUSCH cannot be transmitted in parallel exists or not. And if so, determining the UCI or the multiplexing channel of the data on the PUCCH with the low priority in the PUSCH with the low priority. Otherwise, multiplexing of the low-priority PUCCH and the low-priority PUSCH is not performed.

As an example, fig. 13 is a fourth exemplary diagram of time domain resource overlapping among multiple uplink channels. As shown in fig. 13, CC1 and CC2 are two carriers on the same frequency band, CC3 is a carrier located on a different frequency band from CC1 and CC2, and the terminal supports parallel transmission of PUCCH and PUSCH on CC1 and CC 3. Wherein, one LP PUCCH on CC1 is overlapped with LP PUSCH on CC1, LP PUSCH on CC2, and LP PUSCH on CC3, respectively, and one HP PUCCH on CC1 is overlapped with HP PUSCH on CC 3.

When the time domain resources of multiple uplink channels shown in fig. 13 are overlapped, if the LPPUCCH, LP PUSCH, HP PUCCH, and HP PUSCH in the figure all satisfy the timeline requirement, that is, the terminal knows the overlapping condition between the LPPUCCH, LP PUSCH, HP PUCCH, and HP PUSCH, the terminal knows that the LP PUSCH on CC1 overlaps with the HP PUCCH that cannot be transmitted in parallel. Since the LPPUCCH on CC1 and the LP PUSCH on CC3 can be transmitted in parallel, the LP PUSCH on CC1 and the LP PUSCH on CC2 are alternatives for the multiplexed channel of the LP PUCCH on CC 1. Since the LPPUSCH on CC1 and the HP PUCCH which cannot be transmitted in parallel overlap, the terminal multiplexes the LP PUCCH on CC1 on the LP PUSCH on CC 2.

At this time, in S902, LP PUSCH on CC1 and CC3 is dropped. In S903, the HP PUCCH and the PUSCH may be transmitted in parallel without multiplexing. Finally, the terminal transmits HP PUCCH on CC1, LP HUCCH on CC2 and HP PUSCH on CC 3.

If none of the LPPUCCH, LP PUSCH, HP PUCCH, and HP PUSCH in the figure meet the timeline requirement, that is, the terminal does not know the overlapping condition between LPPUCCH, LP PUSCH, HP PUCCH, and HP PUSCH, the terminal does not know that LP PUSCH on CC1 overlaps with HP PUCCH which cannot be transmitted in parallel. Since it is determined that LP PUCCH on CC1 and LP PUSCH on CC3 can be transmitted in parallel, LP PUSCH on CC1 and LP PUSCH on CC2 are alternatives to the multiplexed lanes of LP PUCCH on CC 1. Since the terminal knows that LP PUSCH on CC1 overlaps with HP PUCCH that cannot be transmitted in parallel, the terminal may multiplex LP PUCCH on LP PUSCH on CC 1.
