[0016] Hereinafter, the uplink channel transmission method, device, and electronic device provided in the embodiments of the present application will be described in detail with reference to the drawings according to specific embodiments and application scenarios.

[0017] 2, which is a flowchart of an uplink transmission method provided in an embodiment of the present application, the uplink transmission method being applied to a terminal. As shown in FIG. 2, the uplink transmission method includes the following steps 201 and 202:

[0018] In step 201, if the uplink channel time domain resources overlap, the terminal handles the overlap between the uplink channels according to a predetermined rule.

[0019] Here, the uplink channels with overlapping time domain resources include uplink channels with different priorities. It can be understood that a terminal can support different services, and different services can meet different service demands, for example, different requirements for uplink channel delay, reliability, etc., and further prioritization of the uplink channels may be performed. Optionally, the priorities of the uplink channels may include high priority and low priority, and the priorities may be indicated by priority indexes, for example, priority index 1 indicates high priority and priority index 0 indicates low priority.

[0020] It should be noted that different uplink channels may have different priority derivation methods, for example, the priorities of the Scheduling Request (SR), Configured Grant Scheduling (CG), Physical Uplink Shared Channel (PUSCH), Semi-Persistent Scheduling (SPS), Physical Downlink Shared Channel (PDSCH), and Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) to be released are configured by Radio Resource Control (RRC) signaling, while Persistent Channel State Information (P-CSI) or Semi-Persistent Channel State Information (SP-CSI) on the Physical Uplink Control Channel (PUCCH) may be considered as low priority, i.e., predefined. The HARQ-ACK of the dynamic scheduling PDSCH, the dynamic scheduling PUSCH, and the aperiodic CSI (A-CSI) or SP-CSI in the PUSCH may be indicated by a one-bit field in the corresponding scheduling downlink control information (DCI), or may be implicitly acquired by a method such as the format of the DCI. The priority of the PUCCH may be determined by the HARQ-ACK, SR, or CSI it carries.

[0021] When selectively multiplexing between channels with different priorities, the priority of the channel on which UCIs with different priorities are multiplexed and transmitted may be determined by the highest priority among the priority of the UCI after multiplexing and the priority of the initial channel, or the priority may remain unchanged. For example, when high-priority UCIs are multiplexed and transmitted on a low-priority PUCCH or PUSCH, the priority may be high or may remain low.

[0022] It should be noted that an uplink transmission channel such as a PUCCH or a PUSCH in the present invention refers to an uplink transmission channel within one PUCCH group or cell group.

[0023] It should be mentioned that the overlap of the uplink channel time domain resources in the present invention may also be called uplink channel time domain resource collision, uplink channel resource collision or uplink channel collision.

[0024] In the embodiment of the present application, when the uplink channel time domain resources overlap, the overlap between the uplink channels needs to be processed first. Specifically, the terminal may process the overlap between the uplink channels according to a predetermined rule, where the predetermined rule is: Uplink channel priority, Type of uplink channel, start time of the uplink channel, Uplink channel allocation status, the capabilities of the terminal, and It relates to at least one item of the configuration information transmitted by the network side device for instructing the transmission overlap processing order of the uplink channel.

[0025] That is, when the uplink channel time domain resources overlap, the terminal may handle the overlap between the uplink channels based on at least one of the six predetermined rules described above. The following describes the predetermined rules in detail according to different embodiments.

[0026] Optionally, when the predetermined rule relates to the priority of the upstream channels, the step of processing overlap between the upstream channels based on a predetermined rule comprises: The method includes a step of processing overlaps between upstream channels with the same priority first, and then processing overlaps between upstream channels with different priorities.

[0027] It can be understood that the uplink channels with overlapping time domain resources include uplink channels with different priorities, for example, a high-priority uplink channel and a low-priority uplink channel; thus, the terminal may first process the overlap between the high-priority uplink channels or the overlap between the low-priority uplink channels, and then process the overlap between the different priorities, for example, first process the overlap between the high-priority uplink channels (if present) or the overlap between the low-priority uplink channels (if present), and then process the overlap between the high-priority uplink channel and the low-priority uplink channel.

[0028] The step of preferentially processing overlapping between uplink channels with the same priority level comprises: The method includes the step of processing overlaps (if any) between PUCCHs with the same priority as a priority, and processing overlaps (if any) between PUCCHs with the same priority as a priority and processing overlaps (if any) between PUSCHs with the same priority as a priority thereafter.

[0029] That is, for overlapping between uplink channels with the same priority, the terminal further processes the overlapping between the uplink channels according to the uplink channel type. For example, when the uplink channels with overlapping time domain resources include uplink channels with different priorities, the terminal first processes the overlapping between PUCCHs and PUCCHs with the same priority (if any), then processes the overlapping between PUCCHs and PUSCHs with the same priority (if any), and then processes the overlapping between uplink channels with different priorities.

[0030] In the embodiments of the present application, overlapping between channels of different types and / or different priorities is handled based on the existence of channels of these types and / or priorities and the existence of overlapping between the channels. Thus, it is necessary to explain that overlapping between channels is handled based on the predetermined rules provided in the embodiments of the present application. In some cases, when channels of all types or priorities are not present or overlapping exists, and no channels related to the predetermined rules provided in the embodiments of the present application exist, the terminal does not need to perform corresponding operations and can handle the overlapping channels according to the specific circumstances. For example, for overlapping between uplink channels of the same priority, if only overlapping between PUCCHs and PUSCHs of the same priority exists and no overlapping between PUCCHs and PUCCHs of the same priority exists, the terminal prioritizes handling the overlapping between PUCCHs and PUSCHs of the same priority. Regarding the overlapping between channels involved in the following embodiments, the terminal can handle the overlapping between existing channels according to the specific circumstances, without considering non-existent channels, and will not be described in detail below to avoid repetition.

[0031] The step of subsequently handling overlap between uplink channels of different priority comprises: The method includes processing overlaps between PUCCHs with different priorities first, and processing overlaps between PUCCHs with different priorities and PUSCHs thereafter.

[0032] That is, for overlaps between uplink channels with different priorities, the terminal can similarly process the overlaps between the uplink channels according to the uplink channel type. For example, after processing overlaps between uplink channels with the same priority, for overlaps between uplink channels with different priorities, the terminal first processes overlaps between PUCCHs and PUCCHs with different priorities, and then processes overlaps between PUCCHs and PUSCHs with different priorities.

[0033] In one specific implementation, when PUCCH and PUSCH include low-priority and high-priority uplink transmissions and overlaps exist, the terminal first processes the overlaps between PUCCHs and PUCCHs with the same priority, then processes the overlaps between PUCCHs and PUSCHs with the same priority, then processes the overlaps between PUCCHs and PUCCHs with different priorities, and then processes the overlaps between PUCCHs and PUSCHs with different priorities.

[0034] In the above embodiment, it can be understood that when the uplink channels with overlapping time domain resources include uplink channels with different priorities, the terminal can process the overlap between the uplink channels based on the priority of the uplink channels, and then transmit the processed uplink channels.

[0035] Optionally, when the predetermined rule relates to a priority of an upstream channel and a type of an upstream channel, the step of processing overlap between upstream channels based on a predetermined rule comprises: Prioritizing overlaps between PUCCHs with the same priority, then processing overlaps between PUCCHs with different priority, and then processing overlaps between PUCCHs with the same priority and PUSCHs; or or, processing overlaps between PUCCHs with the same priority first, processing overlaps between PUCCHs with different priorities thereafter, and then processing overlaps between PUCCHs with different priorities and PUSCHs; or The method includes the steps of: preferentially processing overlaps between PUCCHs with the same priority, subsequently processing overlaps between PUCCHs with different priorities, and then processing overlaps between PUCCHs and PUSCHs.

[0036] That is, when PUCCH and PUSCH include low-priority and high-priority uplink transmissions, for uplink channels with overlapping time domain resources, the overlap between uplink channels may be handled based on the priority and type of the uplink channel.

[0037] In this embodiment, overlap between PUCCHs and PUCCHs is processed preferentially based on the type of uplink channel, and then overlap between PUCCHs and PUSCHs is processed; when the types of uplink channels are the same, overlap between uplink channels is processed based on the priority of the uplink channel, for example, overlap between PUCCHs and PUCCHs with the same priority is processed preferentially, and then overlap between PUCCHs and PUCCHs with different priorities is processed.

[0038] The step of subsequently processing overlap between PUCCH and PUSCH may be to subsequently process overlap between PUCCH and PUSCH with the same priority, or to subsequently process overlap between PUCCH and PUSCH with different priorities, or to preferentially process overlap between PUCCH and PUSCH and then process overlap between PUCCH and PUSCH, regardless of whether PUCCH and PUSCH have the same priority or different priorities.

[0039] In this embodiment, the terminal can process overlapping between uplink channels according to the type of uplink channel and the priority of the uplink channel, and in this way, it can more effectively process overlapping between uplink channels in an orderly manner and ensure the transmission performance of the uplink channel.

[0040] Optionally, when the predetermined rule is related to a type of an upstream channel, the step of processing overlap between upstream channels based on a predetermined rule comprises: The method includes the steps of processing overlap between PUCCH and PUCCH first, and processing overlap between PUCCH and PUSCH thereafter.

[0041] In this embodiment, when uplink channel time domain resources overlap, the terminal first processes the overlap between PUCCHs (regardless of whether the overlapping PUCCHs and PUCCHs have the same priority or different priorities), and then processes the overlap between PUCCHs and PUSCHs (regardless of whether the overlapping PUCCHs and PUSCHs have the same priority or different priorities). In this way, the overlap between uplink channels can be processed based on the type of uplink channel without distinguishing the priority of the uplink channel, which makes the processing of the overlap between uplink channels easier and ensures the processing efficiency of the uplink channel overlap by the terminal.

[0042] Optionally, when the predetermined rule relates to start times of upstream channels, the step of processing overlap between upstream channels based on a predetermined rule comprises: The method includes a step of processing overlapping between upstream channels with earlier start times with priority, and processing overlapping between upstream channels with later start times thereafter.

[0043] The start time includes a start symbol and / or a start time unit of an uplink channel. For example, the start time is a start time unit of an uplink channel, and further, when uplink channel time domain resources overlap, the terminal processes the overlap between uplink channels with an earlier start time unit first, and then processes the overlap between uplink channels with a later start time unit second. Alternatively, the start time may be a start symbol of an uplink channel, and thus the terminal processes the overlap between uplink channels with an earlier start symbol first, and then processes the overlap between uplink channels with a later start symbol second.

[0044] In this embodiment, the processing order of overlapping upstream channels is determined based on the start times of the upstream channels, i.e., the upstream channels are processed in order of earliest start times, which makes the processing of overlapping upstream channels easier.

[0045] Optionally, when the predetermined rule relates to a configuration situation of the upstream channels, the step of processing overlap between the upstream channels based on the predetermined rule comprises: or - processing overlaps between configured uplink channels as a priority and processing overlaps between configured uplink channels and dynamic scheduling uplink channels thereafter; The method includes the step of handling overlaps between allocated uplink channels as a priority and handling overlaps between dynamic scheduling uplink channels thereafter.

[0046] That is, when uplink channel time domain resources overlap, the terminal first processes the overlap between configured uplink channels, and then processes the overlap between dynamic scheduling uplink channels, or processes the overlap between configured uplink channels and dynamic scheduling uplink channels. In this embodiment, the terminal can process the overlap between uplink channels based on the configuration situation of the uplink channels, and because the configured uplink transmission does not rely on dynamic scheduling, the UE can complete the overlap between configured uplink channels without relying on dynamic scheduling, which makes it easier to handle the overlap between uplink channels.

[0047] Alternatively, when uplink channel time domain resources overlap, the terminal may process the overlap between uplink channels according to its capability, where the order in which the terminal processes the overlap between uplink channel time domain resources depends on the terminal's capability. Alternatively, the terminal may process the overlap between uplink channels based on configuration information sent by a network side device, where the configuration information is for indicating the processing order of the overlap between uplink channels. For example, the configuration information may instruct the terminal to process the overlap between PUCCHs and PUCCHs first, and then process the overlap between PUCCHs and PUSCHs. In this way, the terminal processes the overlap between uplink channels in the processing order indicated by the configuration information.

[0048] In an embodiment of the present application, the step of handling overlap between upstream channels comprises: When the PUCCHs overlap, multiplexing the overlapped PUCCHs into one PUCCH and transmitting the PUCCH; and when the PUCCH and the PUSCH overlap, multiplexing at least a portion of uplink control information (UCI) carried on each of the PUCCHs into at least one of the PUSCHs and transmitting the PUCCH.

[0049] Wherein, when a PUCCH overlaps with another PUCCH, the overlapped PUCCH may be multiplexed onto a first PUCCH for transmission, and the first PUCCH may be any of the overlapped PUCCHs, or the overlapped PUCCH may be multiplexed onto a third PUCCH for transmission, and the third PUCCH is a PUCCH other than the first PUCCH and the second PUCCH. For example, the uplink channel transmitted by the terminal includes a first PUCCH and a second PUCCH, and the time domain resources of the first PUCCH and the second PUCCH overlap. Thus, the first PUCCH may be multiplexed onto the second PUCCH for transmission, or the second PUCCH may be multiplexed onto the first PUCCH for transmission, or both the first PUCCH and the second PUCCH may be multiplexed onto a third PUCCH for transmission, and the third PUCCH is a PUCCH resource determined by the number of UCI bits after multiplexing, or is a PUCCH resource for transmitting the multiplexed UCI that is configured. In this way, processing for overlapping PUCCHs is realized, the single carrier characteristics of the terminal are not impaired, and the transmission performance of the uplink channel is ensured.

[0050] When a PUCCH and a PUSCH overlap, UCI carried on all PUCCHs may be multiplexed onto at least one of the PUSCHs for transmission, or some UCI carried on a PUCCH may be multiplexed onto at least one of the PUSCHs for transmission. For example, when HARQ-ACK, CSI, and SR exist as UCI, the UE may multiplex the HARQ-ACK and CSI onto a PUSCH for transmission and discard the SR. Furthermore, for example, when high-priority and low-priority HARQ-ACKs exist, the UE may compress the low-priority HARQ-ACK to a smaller number of bits and then multiplex it together with the high-priority HARQ-ACK onto one PUSCH for transmission. Optionally, when a PUCCH overlaps with only one PUSCH, UCI carried on all PUCCHs may be multiplexed onto this PUSCH for transmission, or some UCI carried on a PUCCH may be multiplexed onto this PUSCH for transmission. When a PUCCH overlaps with multiple PUSCHs, the terminal may select and multiplex one PUSCH from them. For example, the terminal may select and multiplex a PUSCH having A-CSI, or may select and multiplex a PUSCH with the earliest start slot, or, when a dynamic scheduling PUSCH and a grant scheduling PUSCH are included, the terminal may preferentially select and multiplex the dynamic scheduling PUSCH, or may preferentially select and multiplex the PUSCH that is transmitted earliest, or may preferentially select and multiplex a PUSCH with a smaller index of the serving cell in which the terminal is located.

[0051] Alternatively, when uplink channels with overlapping time domain resources have different priorities, the terminal may discard the low-priority (LP) uplink channel and transmit only the high-priority (HP) uplink channel to handle the overlap between the uplink channels. Note that the terminal may discard the low-priority uplink channel and handle the overlap between the high-priority uplink channels for the remaining high-priority channels based on the above-mentioned predetermined rule. For example, when an HP HARQ-ACK and an HP PUSCH overlap, the HP HARQ-ACK may be multiplexed onto the HP PUSCH for transmission.

[0052] Alternatively, in the case of overlap between PUCCHs, the UE may determine whether to multiplex and transmit UCI into one channel or discard some UCI information depending on the PUCCH format and / or the type of UCI carried. For example, if the PUCCH carrying HARQ-ACK is PUCCH format 1 and the PUCCH carrying SR is PUCCH format 0, and the time domain resources of the two PUCCHs overlap, the UE will discard the SR and transmit only the HARQ-ACK PUCCH.

[0053] In this way, by multiplexing or discarding overlapping uplink channels, the single carrier characteristics of the terminal can be avoided from being impaired, the impact on service priority can be reduced, and the transmission performance of the uplink channel can be ensured.

[0054] In step 202, the terminal transmits the processed uplink channel.

[0055] It can be seen that after processing the overlap between the uplink channels according to a predetermined rule, the processed uplink channels are transmitted, so that there are no overlapping uplink channels in the processed uplink channels, and further ensure the single-carrier characteristics of the uplink transmission of the terminal, avoid the degradation of the transmission performance of the uplink channels, and ensure that the terminal has suitable uplink channel transmission performance.

[0056] In order to better understand the means provided in the present application, the following describes the uplink channel transmission method provided in the present application through a specific embodiment. Example 1

[0057] Referring to Figure 3, Figure 3 is a schematic diagram of an uplink channel transmission case. As shown in Figure 3, in a certain time unit, the time domain resources of PUCCHs and PUSCHs with different priorities overlap, specifically including HP (high priority) SR PUCCH, HP HARQ-ACK PUCCH, LP (low priority) HARQ-ACK PUCCH, LP CSI PUCCH, LP PUSCH, and HP PUSCH, where PUCCHs (including HP SR PUCCH, HP HARQ-ACK PUCCH, LP HARQ-ACK PUCCH, and LP CSI PUCCH) are on component carrier (CC) CC0, LP PUSCHs are on CC1, and HP PUSCHs are on CC2. For PUCCHs and PUSCHs with different priorities whose time domain resources overlap as shown in Figure 3, a terminal may use one of the following methods for processing: (Method 1)

[0058] The terminal first processes overlaps between PUCCHs with the same priority, then processes overlaps between PUCCHs with the same priority and PUSCHs, then processes overlaps between PUCCHs with different priorities, and finally processes overlaps between PUCCHs with different priorities and PUSCHs.

[0059] 3, the HP SR PUCCH, HP HARQ-ACK PUCCH, and HP PUSCH have the same priority (i.e., high priority), and the LP HARQ-ACK PUCCH, LP CSI PUCCH, and LP PUSCH have the same priority (i.e., low priority). For overlaps between the HP SR PUCCH, HP HARQ-ACK PUCCH, and HP PUSCH, the UE may multiplex the HP SR PUCCH onto the HP HARQ-ACK PUCCH for transmission, and since the time domain resources of the HP HARQ-ACK PUCCH and HP PUSCH overlap, the UE multiplexes the HP HARQ-ACK onto the HP PUSCH for transmission and discards the HP SR (assuming that the HP PUSCH has an uplink shared channel (UL-SCH)). For overlaps between the LP HARQ-ACK PUCCH, LP CSI PUCCH, and LP PUSCH, the UE may first multiplex the LP HARQ-ACK PUCCH onto one PUCCH resource, for example, a PUCCH resource determined by the number of HARQ-ACK and CSI bits after multiplexing, and transmit the multiplexed PUCCH. If the multiplexed PUCCH resource still overlaps with the time domain resource of the LP PUSCH, the UE multiplexes the LP HARQ-ACK and LP CSI onto the LP PUSCH for transmission (assuming there is no CSI in the LP PUSCH). Since the LP PUSCH and the HP PUSCH are in different serving cells, the UE separately transmits the LP PUSCH and the HP PUSCH multiplexed with UCI.

[0060] In this embodiment, UCIs of different priorities can be multiplexed onto different PUSCHs for transmission, reducing the impact on the transmission performance of the high-priority PUSCH when low-priority UCIs are multiplexed onto a high-priority PUSCH for transmission, and the impact of transmission delay on the high-priority UCI when high-priority UCIs are multiplexed onto a low-priority PUSCH for transmission, and further ensuring favorable uplink transmission performance of the terminal. (Method 2)

[0061] The terminal may preferentially process overlaps between PUCCHs with the same priority, then process overlaps between PUCCHs with different priorities, and then process overlaps between PUCCHs and PUSCHs (whether of the same priority or different priorities).

[0062] Regarding overlap between uplink channels in FIG. 3, for overlap between the HP SR PUCCH and the HP HARQ-ACK PUCCH, the terminal may multiplex the HP SR PUCCH onto the HP HARQ-ACK PUCCH for transmission. For overlap between the LP HARQ-ACK PUCCH and the LP CSI PUCCH, the UE may multiplex the LP HARQ-ACK PUCCH into one PUCCH for transmission, for example, multiplex it into the LP CSI PUCCH for transmission. Next, overlap between uplink channels with different priorities is processed. Since the time domain resources of the LP CSI PUCCH and the HP HARQ-ACK PUCCH overlap, the UE may multiplex the LP CSI PUCCH and the HP HARQ-ACK PUCCH into one channel for transmission. That is, the UE may multiplex the HP SR PUCCH, HP HARQ-ACK PUCCH, LP HARQ-ACK PUCCH, and LP CSI PUCCH into one channel for transmission. If the PUCCH channel after multiplexing overlaps with the time domain resource of the LP PUSCH or the HP PUSCH, the UE may multiplex UCIs with different priorities (including the HP SR PUCCH, HP HARQ-ACK PUCCH, LP HARQ-ACK PUCCH, and LP CSI PUCCH) into the LP CSI PUCCH. Alternatively, the terminal may multiplex the HP SR, the HP HARQ-ACK, the LP HARQ-ACK, and some UCI in the LP CSI onto the LP PUSCH or the HP PUSCH for transmission, for example, the terminal multiplexes the HP HARQ-ACK and the LP HARQ-ACK onto the HP PUSCH for transmission, and discards the HP SR and the LP CSI.

[0063] In this embodiment, UCIs with different priorities can be multiplexed and transmitted on the same PUSCH, and when power is limited, transmission of the PUSCH in which the UCIs are multiplexed and transmitted can be ensured preferentially, thereby ensuring the uplink transmission performance of the terminal and ensuring smooth communication. (Method 3)

[0064] The terminal may process the overlap between PUCCH and PUCCH (whether of the same priority or different priorities) first, and then process the overlap between PUCCH and PUSCH (whether of the same priority or different priorities).

[0065] Regarding overlap between uplink channels in FIG. 3, the UE first processes overlap between the HP SR PUCCH, HP HARQ-ACK PUCCH, LP HARQ-ACK PUCCH, and LP CSI PUCCH, and for example, multiplexes different UCI into one PUCCH for transmission, for example, multiplexes into the LP CSI PUCCH for transmission; alternatively, the UE multiplexes the HP SR, HP HARQ-ACK, and LP HARQ-ACK into one PUCCH for transmission and discards the LP CSI. If the multiplexed PUCCH channel overlaps with the LP PUSCH or the HP PUSCH, the UE multiplexes all or part of the UCI carried in the PUCCH (i.e., a channel into which all or part of the UCI in the HP SR, HP HARQ-ACK, LP HARQ-ACK, and LP CSI are multiplexed) into the LP PUSCH or the HP PUSCH for transmission. Optionally, the terminal may multiplex the HP SR, the HP HARQ-ACK, the LP HARQ-ACK, and some UCI in the LP CSI onto the LP PUSCH or the HP PUSCH for transmission.

[0066] In this embodiment, overlaps between uplink channels are processed based on the type of uplink channel, and when processing overlaps between uplink channels, the terminal only needs to determine the processing order based on the type of uplink channel, regardless of the priority of the uplink channel, thereby simplifying the terminal's processing process. (Method 4)

[0067] The terminal may perform overlap processing based on the start times (start symbol and / or start time units) of the PUCCH and PUSCH.

[0068] Regarding overlap between uplink channels in FIG. 3, the LP PUSCH, HP SR PUCCH, LP HARQ-ACK PUCCH, and LP CSI PUCCH are uplink channels with early start times, and the HP PUSCH and HP HARQ-ACK PUCCH are uplink channels with later start times. The terminal may first process overlap between the LP PUSCH, HP SR PUCCH, LP HARQ-ACK PUCCH, and LP CSI PUCCH, for example, by multiplexing the HP SR PUCCH, LP HARQ-ACK PUCCH, and LP CSI PUCCH onto the LP PUSCH for transmission, or by discarding the HP SR PUCCH or by discarding the LP PUSCH. It is assumed that the UE multiplexes the HP SR PUCCH, the LP HARQ-ACK PUCCH, and the LP CSI PUCCH onto the LP PUSCH for transmission, and then processes the overlap between the HP PUSCH and the HP HARQ-ACK PUCCH, for example, multiplexes the HP HARQ-ACK onto the HP PUSCH for transmission. (Method 5)

[0069] The terminal may process the overlap between the configured uplink channels first, and then process the overlap between the configured uplink channels and the dynamic scheduling uplink channels, or may process the overlap between the dynamic scheduling uplink channels first.

[0070] For example, in Figure 3, only the HP SR PUCCH and the LP CSI PUCCH are configured uplink channels, and the rest are all scheduled uplink channels. The terminal first processes overlap between the HP SR PUCCH and the LP CSI PUCCH, for example, multiplexes the HP SR PUCCH and the LP CSI PUCCH, for example, multiplexes the HP SR PUCCH onto the LP CSI PUCCH for transmission, or discards the LP CSI PUCCH, and then processes overlap between other channels. Example 2

[0071] Referring to Figure 4, Figure 4 is a schematic diagram of another transmission case of the uplink channel. As shown in Figure 4, in a certain time unit, the time domain resources of PUCCH and PUSCH with different priorities overlap, specifically including HP SR PUCCH, HP HARQ-ACK PUCCH, LP HARQ-ACK PUCCH, LP CSI PUCCH, and LP PUSCH, where PUCCH (including HP SR PUCCH, HP HARQ-ACK PUCCH, LP HARQ-ACK PUCCH, and LP CSI PUCCH) is in CC0, and LP PUSCH is in CC1. For PUCCH and PUSCH with different priorities whose time domain resources overlap as shown in Figure 3, the terminal may use the following manner for processing.

[0072] The terminal first processes overlaps between PUCCHs with the same priority, then processes overlaps between PUCCHs with the same priority and PUSCHs, then processes overlaps between PUCCHs with different priorities, and finally processes overlaps between PUCCHs with different priorities and PUSCHs.

[0073] 4, the UE first processes overlap between the HP SR PUCCH and the HP HARQ-ACK PUCCH and overlap between the LP HARQ-ACK PUCCH and the LP CSI PUCCH. For overlap between the HP SR PUCCH and the HP HARQ-ACK PUCCH, the UE may multiplex the HP SR PUCCH onto the HP HARQ-ACK PUCCH for transmission. For overlap between the LP HARQ-ACK PUCCH and the LP CSI PUCCH, the UE may multiplex the LP HARQ-ACK PUCCH onto one PUCCH for transmission, for example, onto the LP CSI PUCCH for transmission. Next, after processing overlap between channels with different priorities, since the HP HARQ-ACK PUCCH overlaps with the time domain resource of the LP CSI PUCCH, the terminal may multiplex the UCI carried on the two PUCCHs. For example, the terminal may multiplex the HP SR, HP HARQ-ACK, LP HARQ-ACK, and LP CSI onto one PUCCH for transmission. If the multiplexed PUCCH overlaps with the time domain resource of the LP PUSCH (for example, the PUCCH is multiplexed onto the HP HARQ-ACK PUCCH), the terminal may multiplex some or all of the UCI onto the LP PUSCH for transmission. For example, the terminal may multiplex the HP SR, HP HARQ-ACK, and LP HARQ-ACK onto the LP PUSCH for transmission, and discard the LP CSI.

[0074] Optionally, for the overlap between the uplink channels in Figure 4, the terminal may process it based on other methods, for example, processing based on the start times of PUCCH and PUSCH, processing based on the type of uplink channel, or processing based on the configuration information of the network side equipment, etc. For specific processing methods, please refer to the descriptions in the above embodiments and will not be described in detail in this embodiment.

[0075] In the embodiment of the present application, when uplink channel time domain resources with different priorities overlap, the terminal can process the overlap between the uplink channels according to a predetermined rule, and then transmit the processed uplink channel, thereby reducing the impact on service priority, avoiding the loss of the single-carrier characteristics of the terminal's uplink transmission, ensuring the transmission performance of the uplink channel, and improving system effectiveness and system efficiency.
