[0039] The uplink channel transmission method, apparatus and electronic device provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0040] Please refer to Figure 2 , Figure 2 is a flowchart of an uplink channel transmission method provided by an embodiment of the present application. The uplink channel transmission method is applied to a terminal. As Figure 2 shown, the uplink channel transmission method includes the following steps:

[0041] Step 201, when there is an overlap in the time-domain resources of the uplink channel, the terminal processes the overlap between the uplink channels based on a preset rule.

[0042] Among them, the uplink channels with overlapping time-domain resources include uplink channels with different priorities. Understandably, a terminal may support different services, and different services correspond to different service requirements. For example, there are different requirements for the delay, reliability, etc. of the uplink channel, and thus the uplink channel can be marked with priorities. Optionally, the priorities of the uplink channels can include high priority and low priority, and the priorities can be represented by priority indices. For example, priority index 1 represents high priority, and priority index 0 represents low priority.

[0043] It should be noted that for different uplink channels, the ways to obtain their priorities can also be different. For example, for the priorities of Scheduling Request (SR), Configured Grant (CG) Physical Uplink Shared Channel (PUSCH), Semi-Persistent-Scheduling (SPS) Physical downlink shared channel (PDSCH), and the release of Hybrid automatic repeat request acknowledgement (HARQ-ACK), they are configured by Radio Resource Control (RRC) signaling. The Persistent Channel State Information (P-CSI) or Semi-Persistent CSI (SP-CSI) on the Physical Uplink Control Channel (PUCCH) can be regarded as low priority, that is, predefined. For the HARQ-ACK of dynamically scheduled PDSCH, dynamically scheduled PUSCH, the Aperiodic CSI (A-CSI) or SP-CSI on PUSCH can be indicated by a 1-bit field in the corresponding scheduling Downlink Control Information (DCI) or implicitly obtained by means such as the format of DCI. The priority of PUCCH can be determined by the HARQ-ACK, SR, or CSI it carries.

[0044] Optionally, when multiplexing between channels with different priorities, for the channel after multiplexing UCI with different priorities, its priority can be determined according to the highest priority among the priorities of the multiplexed UCI and the original channel, or its priority remains unchanged. For example, when high-priority UCI is multiplexed on a low-priority PUCCH or PUSCH, its priority can be high-priority, or its priority remains low-priority.

[0045] It should be noted that the uplink transmission channels such as PUCCH or PUSCH in the present invention refer to the uplink transmission channels within a PUCCH group or a cell group.

[0046] It should be noted that the overlap of the uplink channel time-domain resources in the present invention can also be called the uplink channel time-domain resource conflict, or the uplink channel resource conflict, or the uplink channel conflict.

[0047] In the embodiments of the present application, in the case of uplink channel time-domain resource overlap, it is necessary to first process the overlap between uplink channels. Specifically, the terminal can process the overlap between uplink channels based on a preset rule, where the preset rule is associated with at least one of the following:

[0048] The priority of the uplink channel;

[0049] The type of the uplink channel;

[0050] The start time of the uplink channel;

[0051] The configuration of the uplink channel;

[0052] The capability of the terminal;

[0053] The configuration information sent by the network-side device, where the configuration information is used to indicate the transmission overlap processing order of the uplink channel.

[0054] That is to say, in the case of uplink channel time-domain resource overlap, the terminal can process the overlap between uplink channels based on at least one of the above six preset rules. The following will specifically describe the preset rules through different embodiments.

[0055] Optionally, in the case where the preset rule is associated with the priority of the uplink channel, the processing of the overlap between uplink channels based on the preset rule includes:

[0056] First process the overlap between uplink channels with the same priority, and then process the overlap between uplink channels with different priorities.

[0057] Understandably, the uplink channels with overlapping time-domain resources include uplink channels with different priorities. For example, including uplink channels with high priority and uplink channels with low priority. Then the terminal can first process the overlap between uplink channels with the same high priority or the overlap between uplink channels with the same low priority, and then process the overlap between uplink channels with different priorities. For example, first process the overlap between uplink channels with high priority (if any) or the overlap between uplink channels with low priority (if any), and then process the overlap between the uplink channel with high priority and the uplink channel with low priority.

[0058] Among them, the preferential processing of the overlap between uplink channels with the same priority includes:

[0059] Preferentially process the overlap between PUCCHs with the same priority (if any), and then process the overlap between the PUCCH and PUSCH with the same priority (if any).

[0060] That is to say, for the overlap between uplink channels with the same priority, the terminal will further process the overlap between uplink channels based on the different types of uplink channels. For example, when the uplink channels with overlapping time-domain resources include uplink channels with different priorities, the terminal preferentially processes the overlap between PUCCHs with the same priority (if any), then processes the overlap between the PUCCH and PUSCH with the same priority (if any), and then processes the overlap between uplink channels with different priorities.

[0061] It should be noted that in the embodiments of the present application, the processing of the overlap between different types and / or different priority channels is based on the existence of these types and / or these priority channels, and there is an overlap between the channels. Then, the overlap between channels is processed based on the preset rules provided in the embodiments of the present application. In some cases, not all types or priorities of channels exist or there is an overlap. When the channels involved in the preset rules provided in the embodiments of the present application do not exist, the terminal does not need to perform the corresponding operations, and only needs to process according to the specific situation of the overlapping channels. For example, for the overlap between uplink channels with the same priority, if there is only an overlap between the PUCCH and PUSCH with the same priority, and there is no overlap between the PUCCHs with the same priority, then the terminal also preferentially processes the overlap between the PUCCH and PUSCH with the same priority. For the processing of the overlap between channels involved in the subsequent embodiments, the terminal only needs to process according to the specific situation of the existing overlap between channels, and the non-existent channels can be ignored. To avoid repetition, it will not be elaborated later.

[0062] Among them, the subsequent processing of the overlap between uplink channels with different priorities includes:

[0063] First, handle the overlap between PUCCHs with different priorities, and then handle the overlap between PUCCH and PUSCH with different priorities.

[0064] That is to say, for the overlap between uplink channels with different priorities, the terminal can also further handle the overlap between uplink channels based on the different types of uplink channels. For example, after the terminal handles the overlap between uplink channels with the same priority, for the overlap between uplink channels with different priorities, first handle the overlap between PUCCHs with different priorities, and then handle the overlap between PUCCH and PUSCH with different priorities.

[0065] As a specific implementation manner, when there is an overlap between low-priority and high-priority uplink transmissions in PUCCH and PUSCH, the terminal first handles the overlap between PUCCHs with the same priority, then handles the overlap between PUCCH and PUSCH with the same priority, then handles the overlap between PUCCHs with different priorities, and then handles the overlap between PUCCH and PUSCH with different priorities.

[0066] It can be understood that in the above implementation manner, when the uplink channels with overlapping time-domain resources include uplink channels with different priorities, the terminal can handle the overlap between uplink channels based on the priorities of the uplink channels, and then transmit the processed uplink channels.

[0067] Optionally, when the preset rule is associated with the priority of the uplink channel and the type of the uplink channel, the handling of the overlap between uplink channels based on the preset rule includes:

[0068] First handle the overlap between PUCCHs with the same priority, then handle the overlap between PUCCHs with different priorities, and then handle the overlap between PUCCH and PUSCH with the same priority; or,

[0069] First handle the overlap between PUCCHs with the same priority, then handle the overlap between PUCCHs with different priorities, and then handle the overlap between PUCCH and PUSCH with different priorities; or,

[0070] First handle the overlap between PUCCHs with the same priority, then handle the overlap between PUCCHs with different priorities, and then handle the overlap between PUCCH and PUSCH.

[0071] That is to say, when low-priority and high-priority uplink transmissions are included in PUCCH and PUSCH, for uplink channels with overlapping time-domain resources, the overlap between uplink channels can be processed based on the priority of the uplink channels and the type of the uplink channels.

[0072] In this embodiment, the overlap between PUCCH and PUCCH is preferentially processed based on the type of the uplink channel, and then the overlap between PUCCH and PUSCH is processed; when the types of the uplink channels are the same, the overlap between the uplink channels is processed based on the priority of the uplink channels. For example, the overlap between PUCCH and PUCCH with the same priority is preferentially processed, and then the overlap between PUCCH and PUCCH with different priorities is processed.

[0073] Among them, the processing of the overlap between PUCCH and PUSCH can be: processing the overlap between PUCCH and PUSCH with the same priority; or, processing the overlap between PUCCH and PUSCH with different priorities; or, regardless of whether PUCCH and PUSCH have the same priority or different priorities, after preferentially processing the overlap between PUCCH and PUCCH, then processing the overlap between PUCCH and PUSCH.

[0074] In this embodiment, the terminal can process the overlap between uplink channels by combining the type of the uplink channel and the priority of the uplink channel, so that the overlap between uplink channels can be processed more effectively and orderly, ensuring the transmission performance of the uplink channel.

[0075] Optionally, when the preset rule is associated with the type of the uplink channel, the processing of the overlap between uplink channels based on the preset rule includes:

[0076] Preferentially processing the overlap between PUCCH and PUCCH, and then processing the overlap between PUCCH and PUSCH.

[0077] In this embodiment, when the time-domain resources of the uplink channels overlap, the terminal preferentially processes the overlap between PUCCH and PUCCH (regardless of whether the overlapping PUCCH and PUCCH have the same priority or different priorities), and then processes the overlap between PUCCH and PUSCH (regardless of whether the overlapping PUCCH and PUSCH have the same priority or different priorities). In this way, the overlap between uplink channels can be processed based on the type of the uplink channel, without distinguishing the priority of the uplink channels, making the processing of the overlap between uplink channels simpler and ensuring the processing efficiency of the terminal for the overlap of the uplink channels.

[0078] Optionally, when the preset rule is associated with the start time of the uplink channel, the processing of the overlap between uplink channels based on the preset rule includes:

[0079] Prioritize the processing of the overlap between uplink channels with earlier start times, and then process the overlap between uplink channels with later start times.

[0080] Wherein, the start time includes the start symbol and / or start time unit of the uplink channel. For example, the start time is the start time unit of the uplink channel. Then, in the case of time domain resource overlap of the uplink channel, the terminal prioritizes the processing of the overlap between uplink channels with earlier start time units and then processes the overlap between uplink channels with later start time units. Alternatively, the start time can also be the start symbol of the uplink channel, and the terminal prioritizes the processing of the overlap between uplink channels with earlier start symbols and then processes the overlap between uplink channels with later start symbols.

[0081] In this embodiment, the processing order of the overlap between uplink channels is determined based on the start time of the uplink channel, that is, it is processed in sequence from the earliest to the latest start time of the uplink channel, making the processing of the overlap between uplink channels simpler.

[0082] Optionally, when the preset rule is associated with the configuration of the uplink channel, the processing of the overlap between uplink channels based on the preset rule includes:

[0083] Prioritize the processing of the overlap between configured uplink channels, and then process the overlap between the configured uplink channel and the dynamically scheduled uplink channel; or,

[0084] Prioritize the processing of the overlap between configured uplink channels, and then process the overlap between dynamically scheduled uplink channels.

[0085] That is to say, in the case of time domain resource overlap of the uplink channel, the terminal prioritizes the processing of the overlap between configured uplink channels and then processes the overlap between dynamically scheduled uplink channels, or processes the overlap between the configured uplink channel and the dynamically scheduled uplink channel later. In this embodiment, the terminal can process the overlap between uplink channels based on the configuration of the uplink channel. Since the configured uplink transmission does not depend on dynamic scheduling, the UE can complete the overlap between configured uplink channels without relying on dynamic scheduling, making the processing of the overlap between uplink channels simpler.

[0086] Optionally, in the case of uplink channel time-domain resource overlap, the terminal may process the overlap between uplink channels according to the terminal's capabilities, where the terminal's capabilities determine the order in which the terminal processes the time-domain resource overlap between uplink channels. Alternatively, the terminal may also process the overlap between uplink channels based on the configuration information sent by the network-side device, where the configuration information is used to indicate the processing order of uplink channel overlap. For example, the configuration information may indicate that the terminal preferentially processes the overlap between PUCCH and PUCCH and then processes the overlap between PUCCH and PUSCH, and the terminal will then process the overlap between uplink channels according to the processing order indicated by the configuration information.

[0087] In the embodiments of this application, the processing of the overlap between uplink channels includes at least one of the following:

[0088] In the case of PUCCH and PUCCH overlap, multiplex the overlapping PUCCHs on one PUCCH;

[0089] In the case of PUCCH and PUSCH overlap, multiplex at least part of the uplink control information (UCI) carried by each PUCCH on at least one of the PUSCHs.

[0090] Among them, in the case of PUCCH and PUCCH overlap, the overlapping PUCCHs may be multiplexed on the first PUCCH, and the first PUCCH may be any one of the overlapping PUCCHs, or the overlapping PUCCHs may also be multiplexed on the third PUCCH, where the third PUCCH is a PUCCH other than the first PUCCH and the second PUCCH. For example, the uplink channels transmitted by the terminal include the first PUCCH and the second PUCCH, and the time-domain resources of the first PUCCH and the second PUCCH overlap. Then, the first PUCCH may be multiplexed on the second PUCCH, or the second PUCCH may be multiplexed on the first PUCCH, or both the first PUCCH and the second PUCCH may be multiplexed on the third PUCCH, where the third PUCCH is a PUCCH resource determined according to the number of UCI bits after multiplexing or a configured PUCCH resource for transmitting the multiplexed UCI. In this way, the processing of the overlapping PUCCHs is realized, the single-carrier characteristic of the terminal is avoided from being damaged, and the transmission performance of the uplink channel is ensured.

[0091] In the case where PUCCH and PUSCH overlap, all the UCI carried by PUCCH can be multiplexed onto at least one of the PUSCHs, or some of the UCI carried by PUCCH can be multiplexed onto at least one of the PUSCHs. For example, if the UCI includes HARQ-ACK, CSI, and SR, the UE can multiplex HARQ-ACK and CSI onto the PUSCH and discard the SR. Another example is that if there are high-priority and low-priority HARQ-ACKs, the UE can compress the low-priority HARQ-ACK into fewer bits and multiplex it with the high-priority HARQ-ACK onto one PUSCH. Optionally, if PUCCH overlaps with only one PUSCH, all the UCI carried by PUCCH can be multiplexed onto this PUSCH or some of the UCI carried by PUCCH can be multiplexed onto this PUSCH; if PUCCH overlaps with multiple PUSCHs, the terminal can select one of the PUSCHs for multiplexing: for example, it can select the PUSCH with A-CSI for multiplexing; or select the PUSCH with the earliest starting time slot for multiplexing; or in the case of including dynamically scheduled PUSCH and authorized scheduled PUSCH, preferentially select the dynamically scheduled PUSCH for multiplexing; or preferentially select the PUSCH with an earlier transmission for multiplexing; or preferentially select the PUSCH with a smaller serving cell index for multiplexing.

[0092] Or, if the uplink channels with overlapping time-domain resources have different priorities, the terminal's handling of the overlap between the uplink channels can also be to discard the uplink channel with low priority (LP), and thus the terminal only transmits the uplink channel with high priority (HP). Additionally, when the terminal discards the uplink channel with low priority, among the remaining uplink channels with high priority, the terminal can also handle the overlap between the uplink channels with high priority based on the above preset rules; for example, in the case where HP HARQ-ACK overlaps with HP PUSCH, the HP HARQ-ACK can be multiplexed onto the HP PUSCH.

[0093] Or, for the overlap between PUCCHs, the UE can determine whether to multiplex the UCI onto one channel or discard some of the UCI information according to the format of the PUCCH and / or the type of the UCI carried. For example, the PUCCH carrying HARQ-ACK is in PUCCH format 1, and the PUCCH carrying SR is in PUCCH format 0. If the time-domain resources of the two PUCCHs overlap, the UE discards the SR and only transmits the HARQ-ACK PUCCH.

[0094] In this way, by multiplexing or discarding the overlapping uplink channels, it is possible to avoid damaging the single-carrier characteristics of the terminal, reduce the impact on service priorities, and ensure the transmission performance of the uplink channels.

[0095] Step 202: The terminal transmits the processed uplink channel.

[0096] It can be understood that after processing the overlap between uplink channels based on a preset rule, the processed uplink channel is transmitted. In this way, there are no overlapping uplink channels in the processed uplink channel, which can ensure the single-carrier characteristics of the terminal's uplink transmission, avoid the deterioration of the transmission performance of the uplink channel, and ensure that the terminal has good uplink channel transmission performance.

[0097] To better understand the solution provided by this application, the uplink channel transmission method provided by this application will be described below through specific embodiments.

[0098] Embodiment 1

[0099] Please refer to Figure 3 , Figure 3 which is a schematic diagram of a transmission scenario of the uplink channel. As Figure 3 shown, in a certain time unit, there are time-domain resources of PUCCH and PUSCH with different priorities overlapping, which specifically include: HP (high-priority) SR PUCCH, HP HARQ-ACK PUCCH, LP (low-priority) HARQ-ACK PUCCH, LP CSI PUCCH, LP PUSCH, HP PUSCH; among them, PUCCH (including HP SR PUCCH, HP HARQ-ACK PUCCH, LP HARQ-ACK PUCCH, LP CSI PUCCH) is on carrier unit (Component Carrier, CC) CC0, LP PUSCH is on CC1, and HP PUSCH is on CC2. For Figure 3 the time-domain resources of PUCCH and PUSCH with different priorities overlapping shown in

[0100] Method 1

[0101] The terminal first processes the overlap between PUCCH and PUCCH with the same priority, then processes the overlap between PUCCH and PUSCH with the same priority, then processes the overlap between PUCCH and PUCCH with different priorities, and finally processes the overlap between PUCCH and PUSCH with different priorities.

[0102] Figure 3Among them, HP SR PUCCH, HP HARQ-ACK PUCCH, and HP PUSCH are of the same priority (i.e., high priority), and LP HARQ-ACK PUCCH, LP CSI PUCCH, and LP PUSCH are of the same priority (i.e., low priority); for the overlap between HP SR PUCCH, HP HARQ-ACK PUCCH, and HP PUSCH, the terminal can multiplex HP SR PUCCH on HP HARQ-ACK PUCCH. Since the time-domain resources of HP HARQ-ACK PUCCH and HP PUSCH overlap, HP HARQ-ACK is multiplexed on HP PUSCH, and HP SR is discarded (assuming that HP PUSCH has an Uplink Shared Channel (UL-SCH)); for the overlap between LP HARQ-ACK PUCCH, LP CSI PUCCH, and LP PUSCH, the terminal can first multiplex LP HARQ-ACK PUCCH on a PUCCH resource, such as the PUCCH resource determined according to the number of HARQ-ACK and CSI bits after multiplexing. If the multiplexed PUCCH resource still overlaps with the time-domain resources of LP PUSCH, LP HARQ-ACK and LP CSI are multiplexed on LP PUSCH for transmission (assuming there is no CSI on LP PUSCH); and since LP PUSCH and HP PUSCH are on different serving cells respectively, the terminal transmits LP PUSCH and HP PUSCH multiplexed with UCI respectively.

[0103] In this embodiment, UCI with different priorities can be multiplexed on different PUSCHs for transmission, reducing the impact on the transmission performance of high-priority PUSCH when low-priority UCI is multiplexed on high-priority PUSCH, and the impact on the transmission delay of high-priority UCI when high-priority UCI is multiplexed on low-priority PUSCH, and better ensuring the uplink transmission performance of the terminal.

[0104] Method 2

[0105] The terminal can preferentially handle the overlap between PUCCHs with the same priority, then handle the overlap between PUCCHs with different priorities, and then handle the overlap between PUCCH and PUSCH (regardless of whether they have the same or different priorities).

[0106] For Figure 3Overlap between uplink channels. For the overlap between HP SR PUCCH and HP HARQ-ACK PUCCH, the terminal may multiplex HP SR PUCCH on HP HARQ-ACK PUCCH; for the overlap between LP HARQ-ACK PUCCH and LP CSI PUCCH, the terminal may multiplex LP HARQ-ACK PUCCH on a PUCCH, such as multiplexing it on LP CSI PUCCH; then handle the overlap between uplink channels with different priorities. Since the time-domain resources of LP CSI PUCCH and HP HARQ-ACK PUCCH overlap, the terminal may multiplex LP CSI PUCCH and HP HARQ-ACK PUCCH on one channel, that is, the terminal may multiplex HP SR PUCCH, HP HARQ-ACK PUCCH, LP HARQ-ACK PUCCH and LP CSI PUCCH on one channel. If the multiplexed PUCCH channel overlaps with the time-domain resources of LP PUSCH or HP PUSCH, multiplex different-priority UCIs (including HP SR PUCCH, HP HARQ-ACK PUCCH, LP HARQ-ACK PUCCH and LP CSI PUCCH) on LP PUSCH or HP PUSCH. Optionally, the terminal may also multiplex some of the UCIs in HP SR, HP HARQ-ACK, LP HARQ-ACK and LP CSI on LP PUSCH or HP PUSCH. For example, the terminal multiplexes HP HARQ-ACK and LP HARQ-ACK on HP PUSCH and discards HP SR and LP CSI.

[0107] In this embodiment, different-priority UCIs may be multiplexed on the same PUSCH. In a power-constrained scenario, the transmission of the PUSCH multiplexed with UCI may be preferentially guaranteed to ensure the uplink transmission performance of the terminal and the smoothness of communication.

[0108] Method 3

[0109] The terminal may first handle the overlap between PUCCHs (regardless of whether they have the same priority or different priorities), and then handle the overlap between PUCCH and PUSCH (regardless of whether they have the same priority or different priorities).

[0110] For Figure 3Regarding the overlap between the uplink channels, the terminal first processes the overlap between the HP SR PUCCH, HP HARQ-ACK PUCCH, and the LP HARQ-ACK PUCCH, LP CSI PUCCH. For example, different UCIs are multiplexed on one PUCCH, such as multiplexed on the LP CSI PUCCH. Or the terminal multiplexes the HP SR, HP HARQ-ACK, and LP HARQ-ACK on one PUCCH and discards the LP CSI. If the multiplexed PUCCH channel overlaps with the LP PUSCH or HP PUSCH, the UE multiplexes all or part of the UCI carried by the above PUCCH (i.e., the channel multiplexing all or part of the above HP SR, HP HARQ-ACK, LP HARQ-ACK, LP CSI UCIs) on the LP PUSCH or HP PUSCH. Optionally, the terminal can also multiplex part of the UCIs in the HP SR, HP HARQ-ACK, LP HARQ-ACK, LP CSI on the LP PUSCH or HP PUSCH.

[0111] In this embodiment, the overlap between the uplink and downlink channels is processed based on the type of the uplink channel. When the terminal processes the overlap between the uplink channels, it only needs to determine the processing order according to the type of the uplink channel, without considering the priority of the uplink channel, which can simplify the processing flow of the terminal.

[0112] Method Four

[0113] The terminal can perform the overlap processing according to the start time (start symbol and / or start time unit) of the PUCCH and PUSCH.

[0114] For Figure 3Overlap between uplink channels. LP PUSCH, HP SR PUCCH, LP HARQ-ACK PUCCH, and LP CSI PUCCH are uplink channels with an earlier start time, while HP PUSCH and HP HARQ-ACK PUCCH are uplink channels with a later start time. The terminal can first handle the overlap between LP PUSCH and HP SR PUCCH, LP HARQ-ACK PUCCH, and LP CSI PUCCH. For example, multiplex HP SR PUCCH, LP HARQ-ACK PUCCH, and LP CSI PUCCH on LP PUSCH, or discard HP SR PUCCH, or discard LP PUSCH, etc. Assume the terminal multiplexes HP SR PUCCH, LP HARQ-ACK PUCCH, and LP CSI PUCCH on LP PUSCH, and then handles the overlap between HP PUSCH and HP HARQ-ACK PUCCH. For example, multiplex HP HARQ-ACK on HP PUSCH.

[0115] Method 5

[0116] The terminal can first handle the overlap between the configured uplink channels, then handle the overlap between the configured uplink channels and the dynamically scheduled uplink and downlink channels, or handle the overlap between the dynamically scheduled uplink channels.

[0117] For example Figure 3 Among them, only HP SR PUCCH and LP CSI PUCCH are configured uplink channels, and the others are scheduled uplink channels. The terminal first handles the overlap between HP SR PUCCH and LP CSI PUCCH. For example, multiplex HP SR PUCCH and LP CSI PUCCH, such as multiplexing HP SR PUCCH on LP CSI PUCCH, or it can also be to discard LP CSI PUCCH; then handle the overlap between other channels.

[0118] Embodiment 2

[0119] Please refer to Figure 4 , Figure 4 which is another schematic diagram of the transmission scenario of the uplink channel. As Figure 4As shown, in a certain time unit, there is an overlap in the time-domain resources of PUCCH and PUSCH with different priorities, specifically including: HP SR PUCCH, HP HARQ-ACK PUCCH, LP HARQ-ACK PUCCH, LP CSI PUCCH, LP PUSCH; among them, PUCCH (including HP SR PUCCH, HP HARQ-ACK PUCCH, LP HARQ-ACK PUCCH, LP CSI PUCCH) is on CC0, and LP PUSCH is on CC1.

[0120] the terminal can process them in the following way.

[0122] Optionally, forFigure 4 For the overlap between the uplink channels, the terminal can also perform processing based on other methods.

[0123] In the embodiments of the present application, in the case where the time-domain resources of the uplink channels with different priorities overlap, the terminal can process the overlap between the uplink channels based on a preset rule, and then transmit the processed uplink channels, so as to reduce the impact on the service priority, avoid destroying the single-carrier characteristic of the terminal uplink transmission, ensure the transmission performance of the uplink channels, and improve the effectiveness and efficiency of the system.
