[0057] To better understand the technical solutions provided in the embodiments of this application, the relevant technical principles and concepts that may be involved in the embodiments of this application are explained below.

[0058] The uplink channel transmission method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0059] Please refer to Figure 1 , Figure 1 This is a flowchart of an uplink channel transmission method provided in an embodiment of this application. For example... Figure 1 As shown, the uplink channel transmission method includes the following steps:

[0060] Step 201: In the case of uplink channel time domain overlap, the terminal processes the overlap between uplink channels.

[0061] Understandably, uplink channels may overlap in the time domain due to factors such as start symbols and symbol lengths. Specifically, the uplink channel time domain overlap described in this embodiment includes: overlap between Physical Uplink Control Channels (PUCCHs), where all PUCCHs are on the same serving cell; overlap between PUCCHs and Physical Uplink Shared Channels (PUSCHs), where PUCCHs and PUSCHs can be on the same serving cell or different serving cells (different serving cells within a PUCCH group); or overlap between PUSCHs, where all PUSCHs are on the same cell.

[0062] In this embodiment, when uplink channels overlap in the time domain, the terminal processes the overlap between uplink channels. Optionally, the terminal may process the overlap between PUCCHs first, and then process the overlap between PUCCHs and PUSCHs; or, the terminal may process the overlap between high-priority uplink channels first, and then process the overlap between low-priority uplink channels, etc. It should be noted that the terminal's processing of the overlap between uplink channels may include multiplexing the uplink control information (UCI) carried by the PUCCH onto a certain overlapping PUSCH, or canceling the transmission of low-priority uplink channels (e.g., canceling the transmission of low-priority PUSCHs that overlap with high-priority PUSCHs), etc. The following will describe the specific implementation process of the terminal processing the overlap between uplink channels in this embodiment through several optional implementation methods.

[0063] Implementation Method 1

[0064] In the case of overlapping time domains of PUCCH and PUSCH, the terminal's handling of the overlap between uplink channels includes:

[0065] The terminal multiplexes the UCI onto a target PUSCH in an overlapping PUSCH, wherein the target PUSCH is determined based on a preset order.

[0066] In this embodiment, if the time domain resources of PUCCH and PUSCH overlap, the terminal will multiplex the UCI onto one of the overlapping PUSCHs (i.e., the target PUSCH); wherein, the terminal may select the PUSCH for UCI multiplexing in a preset order.

[0067] Optionally, the highest priority PUSCH in the preset order is the high priority (HP) PUSCH. That is, if the overlapping PUSCHs include HP PUSCHs, then the HP PUSCH is selected as the PUSCH for UCI multiplexing.

[0068] It should be noted that the second item in the preset order is the PUSCH containing Aperiodic Channel State Information (A-CSI). That is, if the overlapping PUSCHs include multiple HP PUSCHs, or do not include any HP PUSCHs, then the PUSCH with A-CSI is selected as the PUSCH for UCI multiplexing. It should also be noted that if the overlapping PUSCHs include multiple HP PUSCHs, then the UCI multiplexing PUSCH is selected from among the multiple HP PUSCHs according to the preset order; if the overlapping PUSCHs do not include HP PUSCHs, i.e., the overlapping are LP PUSCHs, then the UCI multiplexing PUSCH is selected from among the LP PUSCHs according to the preset order.

[0069] Furthermore, the third PUSCH in the preset order is the PUSCH with the earliest starting time slot. That is, if the overlapping PUSCHs do not include a PUSCH with A-CSI or there are multiple PUSCHs with A-CSI, then the PUSCH with the earliest starting time slot is selected as the PUSCH for UCI multiplexing.

[0070] Optionally, the fourth order in the preset sequence is the dynamically scheduled PUSCH, the configuration-authorized PUSCH, and the semi-static PUSCH, with the dynamically scheduled PUSCH having a higher order than the configuration-authorized PUSCH and the semi-static PUSCH. That is, if the overlapping PUSCHs include multiple PUSCHs with the same starting time slot, the dynamically scheduled PUSCH is preferentially selected as the PUSCH for UCI multiplexing; if there is no dynamically scheduled PUSCH, then either the configuration-authorized PUSCH or the semi-static PUSCH is selected as the PUSCH for UCI multiplexing.

[0071] Furthermore, the fifth PUSCH in the preset order is related to the index value of the serving cell where the PUSCH resides. Specifically, the PUSCH with a smaller index value in its serving cell has a higher order than the PUSCH with a larger index value. In other words, if overlapping PUSCHs include multiple PUSCHs corresponding to the aforementioned four orders, the PUSCH with the smaller index value in its serving cell is preferentially selected as the PUSCH for UCI multiplexing.

[0072] Furthermore, the sixth PUSCH in the preset order is related to the transmission time of the PUSCHs. Specifically, the PUSCH transmitted earlier has a higher order than the PUSCH transmitted later. That is, if the overlapping PUSCHs include multiple PUSCHs corresponding to the aforementioned five orders, the PUSCH transmitted earlier is preferentially selected as the PUSCH for UCI multiplexing.

[0073] Optionally, in this embodiment, when time-domain resources overlap between PUCCHs of different priorities, or between PUSCHs of different priorities, the first step is: the terminal first processes the overlap between PUCCHs, including PUCCHs of the same priority and PUCCHs of different priorities; for example, the terminal may multiplex PUCCHs without considering their priorities. The second step: if the serving cell of a low-priority (LP) PUSCH has an HP PUSCH with time-domain resources overlapping with the LP PUSCH, the terminal may cancel the transmission of the LP PUSCH. It should be noted that the second step can also be performed before the first step, or the terminal can perform the second step after multiplexing the UCI onto the target PUSCH in the overlapping PUSCHs.

[0074] Optionally, in one embodiment, the terminal supports multiplexing uplink channels of different priorities but does not support simultaneous transmission of different types of uplink channels. That is, the terminal can support multiplexing between PUCCH and PUSCH of different priorities and / or between PUCCH and PUSCH of different priorities, but does not support simultaneous transmission of PUCCH and PUSCH. In this embodiment, for overlap between uplink channels, the terminal multiplexes PUCCH and PUCCH, or multiplexes the UCI carried by the PUCCH onto the PUSCH, or cancels the transmission of the lower-priority PUSCH for overlap between PUSCH of different priorities, thereby processing the overlap between uplink channels. In this way, there are no overlapping uplink channels after processing, ensuring the single-carrier characteristic of the terminal's uplink transmission, while also improving the effectiveness and transmission performance of the communication system.

[0075] Implementation Method 2

[0076] Optionally, the terminal's processing of overlap between uplink channels includes:

[0077] The terminal first processes the overlap between PUCCHs of the same priority and the overlap between PUSCHs of different priorities, and then processes the overlap between other uplink channels of different priorities, so as to multiplex the UCI carried by different PUCCHs onto one PUCCH, or multiplex the UCI carried by the PUCCH onto the PUSCH.

[0078] In this embodiment, the terminal first processes the overlap between PUCCHs of the same priority or the overlap between PUSCHs of different priorities, and then processes the overlap between other uplink channels of different priorities. For example, the terminal first processes the overlap between PUCCHs of the same priority, and the overlap between LP PUSCH and HP PUSCH (for example, if the serving cell of LP PUSCH has HP PUSCH, the transmission of LP PUSCH is canceled). If LP PUCCH overlaps with HP PUCCH, the terminal then processes the overlap between uplink channels of different priorities according to the overlap between LP PUCCH and HP PUCCH and other serving cell PUSCHs. For details, please refer to the description in the following embodiments, which will not be described in detail here.

[0079] Optionally, the terminal first processes the overlap between PUCCHs and the overlap between PUSCHs of different priorities, including:

[0080] The terminal first processes the overlap between PUCCHs of the same priority. If the serving cell of the low-priority LP PUSCH contains an HP PUSCH that overlaps with the LP PUSCH in the time domain, the terminal then cancels the transmission of the LP PUSCH that overlaps with the HP PUSCH in the time domain; or...

[0081] If there is an HP PUSCH in the serving cell where the low-priority LP PUSCH is located that overlaps with the time domain of the LP PUSCH, the terminal first cancels the transmission of the LP PUSCH that overlaps with the HP PUSCH in the time domain, and then processes the time domain overlap between PUCCHs of the same priority.

[0082] For example, in one scheme, the first step is as follows: The terminal first processes the overlap between PUCCHs of the same priority, that is, the overlap between LP PUCCHs and HP PUCCHs; for example, it processes the overlap between LP PUCCHs first, and then the overlap between HP PUCCHs, or it can process the overlap between HP PUCCHs first, and then the overlap between LP PUCCHs; or it can process the overlap between HP PUCCHs and HP PUCCHs, and the overlap between LP PUCCHs in parallel. The second step is: If there is an HP PUSCH in the serving cell that overlaps with the LP PUSCH in the time domain, the terminal cancels the transmission of the LPPUSCH, thus retaining only the transmission of the HP PUSCH. The third step is: The terminal processes the overlap between uplink channels of different priorities.

[0083] Alternatively, in another approach, the first step is as follows: if an HP PUSCH exists in the serving cell where the LP PUSCH is located, overlapping with the LP PUSCH in the time domain, the terminal first cancels the transmission of the LP PUSCH; the second step is that the terminal then processes the overlap between PUCCHs of the same priority, as described in the above approach; the third step is that the terminal processes the overlap between uplink channels of different priorities.

[0084] The terminal handles the overlap between uplink channels of different priorities using the following schemes.

[0085] Optionally, when the time domains of the LP PUCCH and HP PUCCH overlap, and neither the LP PUCCH nor the HP PUCCH overlaps with the time domains of the PUSCH of other serving cells, the terminal processes the overlap between uplink channels of different priorities to multiplex the UCI carried by the PUCCH onto the PUSCH, including:

[0086] If the HP PUSCH and the HP PUCCH overlap in the time domain on the PUCCH cell, the terminal multiplexes the HP UCI carried by the HP PUCCH onto the HP PUSCH; or...

[0087] When there is temporal overlap between LP PUSCH and LP PUCCH on the PUCCH cell, the terminal multiplexes the LP UCI carried by the LPPUCCH onto the LP PUSCH.

[0088] The PUCCH cell can be a primary cell (PCell), a primary secondary cell (PSCell), a PUCCH Scell, etc.

[0089] In one scheme, if the time domains of LP PUCCH and HP PUCCH overlap, and neither LP PUCCH nor HP PUCCH overlaps with the time domains of PUSCH of other serving cells, then if there is a time domain overlap between HP PUSCH and HP PUCCH on the PUCCH cell, the terminal will multiplex the HP UCI carried by the HP PUCCH onto the HP PUSCH.

[0090] Alternatively, in another scheme, if the time domains of LP PUCCH and HP PUCCH overlap, and neither LP PUCCH nor HP PUCCH overlaps with the time domains of PUSCH of other serving cells, then if there is a time domain overlap between LPPUSCH and LP PUCCH on the PUCCH cell, the terminal will multiplex the LP UCI carried by the LP PUCCH onto the LPPUSCH.

[0091] Furthermore, following the above scheme, the method further includes:

[0092] In the event of overlap between uplink channels of different priorities in the PUCCH cell, the terminal cancels the transmission of LP PUSCH and / or LP PUCCH.

[0093] In other words, after the terminal processes the time-domain overlap of HP PUSCH and HP PUCCH on the PUCCH cell, or processes the time-domain overlap of LP PUSCH and LP PUCCH on the PUCCH cell, if the time-domain overlap of LP PUCCH and HP PUSCH still exists on the PUCCH cell, the terminal cancels the transmission of the LP PUCCH; or if the time-domain overlap of LP PUSCH and HP PUCCH still exists on the PUCCH cell, the terminal cancels the transmission of the LP PUSCH; or if the time-domain overlap of LP PUCCH and HP PUCCH still exists on the PUCCH cell, the terminal cancels the transmission of the LP PUCCH; or if the time-domain overlap of LP PUSCH and HP PUSCH still exists on the PUCCH cell, the terminal cancels the transmission of the LP PUSCH.

[0094] In this way, the terminal can perform targeted processing on the overlap between uplink channels on the PUCCH cell to ensure the effectiveness and performance of the terminal's uplink transmission.

[0095] Optionally, in this embodiment, when the first target PUCCH overlaps in the time domain with the target PUSCH of other serving cells, the terminal processes the overlap between other uplink channels of different priorities to multiplex the UCI carried by the PUCCH onto the PUSCH, including:

[0096] The terminal multiplexes the first target PUCCH with the target PUSCH of the other serving cells;

[0097] Wherein, the first target PUCCH is a PUCCH with different priorities that overlaps in the time domain with the target PUSCH of other serving cells, and the number of the first target PUCCH is one, and the target PUSCH has the same priority as the first target PUCCH.

[0098] Specifically, when the time domains of LP PUCCH and HP PUCCH overlap, if only one PUCCH 1 (i.e., the first target PUCCH) in LP PUCCH and HP PUCCH overlaps with a PUSCH of the same priority from another serving cell, the terminal will reuse that PUCCH 1 with the PUSCH of the same priority from the other serving cell.

[0099] Furthermore, when a PUSCH cell has a PUSCH with the same priority as the second target PUCCH in its temporal domain that overlaps with the second target PUCCH, the method further includes:

[0100] The terminal multiplexes the UCI (optionally, excluding SR) carried by the second target PUCCH onto the PUSCH in the PUCCHcell; wherein, the second target PUCCH is a PUCCH other than the first target PUCCH among the PUCCHs of different priorities.

[0101] In other words, when the time domains of LP PUCCH and HP PUCCH overlap, assuming that the PUCCH other than PUCCH 1 (i.e., the first target PUCCH) in LP PUCCH and HP PUCCH is PUCCH 2 (i.e., the second target PUCCH), if there is a PUSCH with the same priority as PUCCH 2 in the PUCCH cell that overlaps with the time domain of PUCCH 2, then the UCI carried by PUCCH 2 will be multiplexed onto the PUSCH on the PUCCH cell.

[0102] Optionally, in this embodiment, when the LP PUCCH overlaps in the time domain with low-priority PUSCHs of other serving cells, and the HP PUCCH overlaps in the time domain with high-priority PUSCHs of other serving cells, the terminal processes the overlap between other uplink channels of different priorities to multiplex the UCI carried by the PUCCH onto the PUSCH, including:

[0103] The terminal multiplexes the third target PUCCH with other low-priority PUSCHs of the serving cell; wherein the third target PUCCH is the LP PUCCH or the HP PUCCH, and the third target PUCCH is determined according to any one of the following:

[0104] The start symbol time of the LP PUCCH and the HP PUCCH;

[0105] Network-side device configuration;

[0106] Network-side device indication;

[0107] The contents carried by the LP PUCCH and the HP PUCCH;

[0108] The scheduling method of the LP PUCCH and the HP PUCCH.

[0109] Specifically, when the time domains of LP PUCCH and HP PUCCH overlap, if both LP PUCCH and HP PUCCH overlap with the time domains of PUSCH of the same priority as other serving cells, that is, LP PUCCH overlaps with the time domains of LP PUSCH of other serving cells, and HP PUCCH overlaps with the time domains of HP PUSCH of other serving cells, then the terminal will multiplex PUCCH 3 with other PUSCH of the same priority. Specifically, PUCCH 3 can be the LPPUCCH that overlaps in time domain with the LP PUSCH of another serving cell; or the HP PUCCH that overlaps in time domain with the HP PUSCH of another serving cell; or PUCCH 3 can be determined based on the start symbol, for example, the PUCCH with the earlier start symbol can be identified as PUCCH 3; or PUCCH 3 can be determined based on network-side device configuration or network-side device indication, for example, the network-side device may indicate that the HP PUCCH is PUCCH 3; or PUCCH 3 can be determined based on the content or scheduling method carried by the LP PUCCH and the HP PUCCH, for example, the PUCCH carrying Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK) or CSI can be identified as PUCCH 3.

[0110] It should be noted that in the above-described scheme of this second embodiment, the terminal supports simultaneous transmission of different types of uplink channels but does not support multiplexing between uplink channels of different priorities. Thus, after processing the overlap between uplink channels, the terminal can achieve simultaneous transmission of different types of uplink channels and multiplexing between uplink channels of the same priority, thereby ensuring the effectiveness and performance of the terminal's uplink transmission.

[0111] Implementation Method 3

[0112] The terminal's processing of overlap between uplink channels includes:

[0113] The terminal processes the overlap between high-priority uplink channels and cancels the transmission of LP PUSCH. Specifically, when there is time-domain overlap between high-priority uplink channels of different types, the HP PUCCH-bearing HPUCI is multiplexed onto HP PUSCH.

[0114] The terminal processes the overlap between low-priority uplink channels. When there is temporal overlap between different types of low-priority uplink channels, the LP UCI carried by the LP PUCCH is multiplexed onto the LP PUSCH.

[0115] The terminal transmits HP PUSCH multiplexed with HP UCI and LP PUSCH multiplexed with LP UCI, respectively.

[0116] In this embodiment, the first step is as follows: The terminal first processes the overlap between high-priority uplink channels, that is, it processes the overlap between HP PUCCH and HP PUCCH, and / or the overlap between HP PUCCH and HP PUSCH. For the overlap between HP PUCCH and HP PUCCH, the terminal can multiplex the HP PUCCHs, for example, multiplexing the UCI carried by each HP PUCCH onto one HP PUCCH. For the overlap between HP PUCCH and HP PUSCH, the terminal multiplexes the HP PUCCH carrying the HP UCI onto the HP PUSCH. The second step is as follows: The terminal processes the overlap between low-priority uplink channels, that is, it processes the overlap between LP PUCCH and LP PUCCH, and / or the overlap between LP PUCCH and LPPUSCH. For the overlap between LP PUCCH and LP PUSCH, the terminal multiplexes the LP UCI carried by the LP PUCCH onto the LP PUSCH. Step 3: The terminal transmits HP PUSCH (which uses HP UCI) and LP PUSCH (which uses LP UCI) respectively.

[0117] Optionally, the terminal's processing of overlap between high-priority uplink channels and cancellation of LP PUSCH transmission includes any one of the following:

[0118] When there is time domain overlap between HP PUSCH and LP PUSCH in the serving cell where LP PUSCH is located, the terminal first processes the overlap between high-priority uplink channels, and then cancels the transmission of LP PUSCH.

[0119] When there is time domain overlap between HP PUSCH and LP PUSCH in the serving cell where LP PUSCH is located, the terminal first cancels the transmission of LP PUSCH, and then processes the overlap between high-priority uplink channels.

[0120] When there is time domain overlap between HP PUCCH and LP PUSCH in the serving cell where LP PUSCH is located, the terminal first processes the overlap between high-priority uplink channels, and then cancels the transmission of LP PUSCH.

[0121] If the HP PUCCH and LP PUSCH overlap in the time domain of the serving cell where the LP PUSCH is located, the terminal first cancels the transmission of the LP PUSCH, and then processes the overlap between high-priority uplink channels.

[0122] For example, in one scheme, if the serving cell where the LP PUSCH is located has time-domain overlap between the HP PUSCH and the LP PUSCH, the terminal first processes the overlap between HP PUCCH and HP PUCCH, and / or the overlap between HP PUCCH and HP PUSCH, and then cancels the transmission of the LP PUSCH.

[0123] Alternatively, in another approach, if the serving cell where the LP PUSCH is located has time-domain overlap between the HP PUSCH and the LP PUSCH, the terminal may first cancel the transmission of the LP PUSCH, and then process the overlap between HP PUCCH and HP PUCCH, and / or the overlap between HP PUCCH and HP PUSCH.

[0124] Alternatively, in another approach, if the serving cell where the LP PUSCH is located has time-domain overlap between the HP PUCCH and the LP PUSCH, the terminal may first process the overlap between HP PUCCH and HP PUCCH, and / or the overlap between HP PUCCH and HPPUSCH, and then cancel the transmission of the LP PUSCH.

[0125] Alternatively, in another approach, if the serving cell where the LP PUSCH is located has time-domain overlap between the HP PUCCH and the LP PUSCH, the terminal may first cancel the transmission of the LP PUSCH, and then process the overlap between the HP PUCCH and the HP PUCCH, and / or the overlap between the HP PUCCH and the HP PUSCH.

[0126] In this way, the terminal can flexibly adopt different processing methods according to the time domain overlap of the uplink channel to ensure the effectiveness of the uplink transmission.

[0127] It should be noted that in this third embodiment, the terminal supports simultaneous transmission of different types of uplink channels. Thus, after processing the overlap between uplink channels, the terminal can support simultaneous transmission of PUCCH and PUSCH, and can multiplex the UCI carried by the PUCCH onto the PUSCH with the same priority, thereby supporting multiplexed transmission of uplink channels, ensuring the effectiveness of the terminal's uplink transmission, and improving the terminal's transmission performance.

[0128] Implementation Method 4

[0129] The terminal's processing of overlap between uplink channels includes:

[0130] The terminal processes the overlap between PUCCH and PUCCH;

[0131] The terminal processes the overlap between LP PUSCH and HP PUSCH, or, if LP PUSCH and PUCCH are in the same serving cell, the terminal processes the overlap between LP PUSCH and PUCCH.

[0132] The terminal transmits PUCCH and PUSCH respectively.

[0133] In this implementation, the first step is that the terminal first processes the overlap between PUCCH and PUCCH, for example, the terminal multiplexes PUCCH and PUCCH, multiplexing the UCI carried by each PUCCH onto one PUCCH; the second step is that the terminal processes the overlap between LPPUSCH and HP PUSCH, or, if LP PUSCH and PUCCH are in the same serving cell, the terminal in the second step can also process the overlap between LP PUSCH and PUCCH in the same serving cell, for example, the terminal cancels LP PUSCH transmission; the third step is that the terminal transmits the processed PUCCH and PUSCH separately.

[0134] It should be noted that in this fourth embodiment, the terminal supports multiplexing of uplink channels of different priorities and supports simultaneous transmission of different types of uplink channels. Thus, after processing the overlap between uplink channels, the terminal can achieve both multiplexed transmission of uplink channels of different priorities and simultaneous transmission of PUCCH and PUSCH, ensuring the effectiveness of the terminal's uplink transmission and improving the terminal's transmission performance.

[0135] Implementation Method 5:

[0136] The terminal's processing of overlap between uplink channels includes:

[0137] The terminal processes the overlap between LP PUSCH and HP PUSCH, or, if LP PUSCH and PUCCH are in the same serving cell, the terminal processes the overlap between LP PUSCH and PUCCH.

[0138] The terminal processes the overlap between PUCCH and PUCCH;

[0139] The terminal transmits PUCCH and PUSCH respectively.

[0140] In this implementation, the first step is that the terminal processes the overlap between the LP PUSCH and HP PUSCH. Alternatively, if the LP PUSCH and PUCCH are in the same serving cell, the terminal can also process the overlap between the LP PUSCH and the PUCCH in the same serving cell in the first step. The second step is that the terminal processes the overlap between PUCCHs, for example, by multiplexing the UCI carried by each PUCCH onto one PUCCH. The third step is that the terminal transmits the processed PUCCH and PUSCH separately. This fifth implementation differs from the fourth implementation only in the execution order of the first and second steps.

[0141] It should be noted that in this fifth embodiment, the terminal supports multiplexing of uplink channels of different priorities and supports simultaneous transmission of different types of uplink channels. Thus, after processing the overlap between uplink channels, the terminal can achieve both multiplexed transmission of uplink channels of different priorities and simultaneous transmission of PUCCH and PUSCH, ensuring the effectiveness of the terminal's uplink transmission and improving the terminal's transmission performance.

[0142] Step 202: The terminal transmits the processed uplink channel.

[0143] The transmission includes at least one of the following: simultaneous transmission of different types of uplink channels, and multiplexing transmission between uplink channels of different priorities.

[0144] In this embodiment, when uplink channels overlap in the time domain, the terminal processes the overlap between uplink channels and transmits the processed uplink channels. This enables the terminal to support simultaneous transmission of different types of uplink channels, such as simultaneous transmission of PUCCH and PUSCH, and to support multiplexing transmission between uplink channels of different priorities. For example, the UCI carried by PUCCH is multiplexed onto PUSCH for transmission. Specific details can be found in the descriptions of the above embodiments. Thus, there are no overlapping uplink channels after processing. Multiplexing and simultaneous transmission between uplink channels improve the effectiveness of the communication system, avoids unnecessary dropping of low-priority channels, and enhances the terminal's transmission performance.

[0145] Optionally, the terminal's capabilities include at least one of the following:

[0146] Supports simultaneous transmission of PUCCH and PUSCH with the same priority on different carriers;

[0147] It supports simultaneous transmission of PUCCH and PUSCH with different priorities on different carriers;

[0148] Supports multiplexing of PUCCHs with the same priority;

[0149] Supports multiplexing of PUCCH and PUSCH with the same priority;

[0150] Supports multiplexing of PUCCH with different priorities and between PUCCH;

[0151] Supports multiplexing of PUCCH and PUSCH with different priorities.

[0152] For example, the terminal may support simultaneous transmission of LP PUCCH and LP PUSCH, as well as HP PUCCH and HP PUSCH, on different carriers, and also support multiplexing between LP PUCCH and HP PUCCH; or, the terminal may also support simultaneous transmission of LPPUCCH and HP PUSCH, as well as HP PUCCH and LP PUSCH, on different carriers, and also support multiplexing between LP PUCCH and HP PUCCH, and support multiplexing between LP PUCCH and LP PUSCH, etc. It is understood that the terminal's capabilities may also include other aspects, which will not be listed in this embodiment.

[0153] To better understand the technical solutions provided in the embodiments of this application, the embodiments of this application will be described below through specific implementation schemes.

[0154] Please refer to Figure 3a , Figure 3aThis is one of the schematic diagrams illustrating the uplink channel transmission scenario applicable to the embodiments of this application. For example... Figure 3a As shown, there is a PUCCH on the PCell. This PUCCH can be an LP PUCCH, an HP PUCCH, or a PUCCH that reuses both the LP UCI and the HP UCI. This PUCCH has temporal overlap with the LP PUSCH on SCell 1 and the HP PUSCH on SCell 2 in the secondary cell (SCell).

[0155] Understandably, based on the description of the above-described embodiment, when a PUCCH overlaps with multiple PUSCHs, the terminal can select one of the PUSCHs based on preset rules to reuse the UCI carried by the PUCCH. Figure 3a If HPPUSCH exists, the terminal will multiplex the UCI carried by the PUCCH in PCell to the HP PUSCH in SCell 2. This multiplexing can be full or partial. For example, it can be multiplexing only HARQ-ACK, or multiplexing HARQ-ACK and CSI.

[0156] Please refer to Figure 3b , Figure 3b This is the second schematic diagram of an uplink channel transmission scenario applicable to the embodiments of this application. For example... Figure 3b As shown, there are LP PUCCH and HP PUCCH on PCell, and these LP PUCCH and HP PUCCH overlap in the time domain with LP PUSCH on SCell 1 and HP PUSCH on SCell 2.

[0157] In response to the above Figure 3b Regarding the temporal overlap between the uplink and midlink channels, based on the processing method described in Implementation Method 2 above, the terminal can employ two different schemes to handle the temporal overlap and transmit the uplink channels. In Scheme 1, the terminal multiplexes the UCI carried by the LP PUCCH onto the LP PUSCH on SCell1 for transmission, and then the terminal transmits the HP PUCCH, HP PUSCH, and the LP PUSCH multiplexed with the LP UCI, respectively.

[0158] Alternatively, in Scheme 2, the terminal multiplexes the UCI carried by the HP PUCCH onto the HP PUSCH of SCell 2 for transmission, and then the terminal transmits the LP PUCCH, LP PUSCH and the HP PUSCH multiplexed with the HP UCI respectively.

[0159] The terminal can determine whether to adopt Scheme 1 or Scheme 2 based on any of the following: predefined principles, network-side device configuration, network-side device indication, PUCCH start symbol, PUCCH scheduling method, and UCI type carried by PUCCH. Specifically, refer to the description in Implementation Method 2 above; it will not be repeated here.

[0160] Alternatively, in Scheme 3, the terminal cancels the transmission of LP PUSCH on SCell 1, multiplexes the UCI carried by HP PUCCH onto HP PUSCH on SCell 2, and then the terminal transmits LP PUCCH on PCell and HP PUSCH multiplexed with HP UCI on SCell respectively.

[0161] Please refer to Figure 3c , Figure 3c This is the third schematic diagram of the uplink channel transmission scenario applicable to the embodiments of this application. For example... Figure 3c As shown, LP PUCCH, HP PUCCH and LP PUSCH have temporal overlap on PCell, while only HP PUSCH is present on SCell.

[0162] In this case, the terminal can multiplex the UCI carried by the LP PUCCH onto the LP PUSCH, and multiplex the UCI carried by the HPPUCCH onto the HP PUSCH. Then, the terminal transmits the LP PUSCH multiplexed with the LP UCI and the HP PUSCH multiplexed with the HP UCI on the Pcell and Scell, respectively.

[0163] Please refer to Figure 3d , Figure 3d This is the fourth schematic diagram of the uplink channel transmission scenario applicable to the embodiments of this application. Figure 3d As shown, there are time-domain overlapping LP PUCCH, HP PUCCH and LP PUSCH on PCell, and these uplink channels do not overlap with uplink channels on other serving cells (such as Scell).

[0164] In this case, the terminal can cancel the transmission of low-priority uplink channels on the PCcell, that is, cancel the transmission of LPPUCCH and LP PUSCH, and only transmit HP PUCCH on the Pcell.

[0165] Please refer to Figure 3e , Figure 3e This is the fifth schematic diagram of the uplink channel transmission scenario applicable to the embodiments of this application. Figure 3eAs shown, there are time-domain overlapping LP PUCCH, HP PUCCH and HP PUSCH on PCell, and these uplink channels do not overlap with uplink channels on other serving cells (such as Scell).

[0166] In this case, the terminal can cancel the transmission of the low-priority uplink channel on the PCcell, that is, cancel the transmission of LPPUCCH, and multiplex the UCI carried by HP PUCCH onto HP PUSCH. Then the terminal transmits the HP PUSCH multiplexed with HP UCI on the Pcell.

[0167] Please refer to Figure 3f , Figure 3g and Figure 3h These are schematic diagrams six, seven, and eight illustrating uplink channel transmission scenarios applicable to the embodiments of this application. Figure 3f As shown, there are temporally overlapping LP PUCCH and HP PUCCH on PCell, and temporally overlapping LP PUSCH and HP PUSCH on SCell; as Figure 3g As shown, PCell only has LP PUCCH, while SCell has temporally overlapping LP PUSCH and HP PUSCH; as Figure 3h As shown, LP PUCCH, HP PUCCH and LP PUSCH have temporal overlap on PCell, while only HP PUSCH is present on SCell.

[0178] Step 1: The terminal handles the overlap between LP PUSCH and HP PUSCH, for example, canceling LP PUSCH transmission; Step 2: The terminal transmits LP PUSCH on Pcell and HP PUSCH on Scell ​​respectively.

[0179] Based on the above implementation method four, for Figure 3h :

[0180] Step 1: The terminal first handles the overlap between LP PUCCH and HP PUCCH, for example, by multiplexing LP UCI and HP UCI. Step 2: If the PUCCH multiplexed in Step 1 overlaps with LP PUSCH, the overlap between PUCCH and LP PUSCH is handled, for example, by canceling the transmission of LP PUSCH, or by multiplexing UCI onto a specific PUSCH. Step 3: The terminal transmits the PUCCH multiplexed with LP UCI and HP UCI on the Pcell and transmits the HP PUSCH on the Scell; or, the terminal transmits the LP PUSCH on the Pcell and transmits the HP PUSCH on the Scell, where one channel of LP PUSCH and HP PUSCH multiplexes LP UCI and HP UCI.

[0181] Please refer to Figure 3i , Figure 3j and Figure 3k These are schematic diagrams nine, ten, and eleven, respectively, illustrating the uplink channel transmission scenarios applicable to the embodiments of this application. Figure 3i As shown, PCcell has temporally overlapping LP PUCCH and LP PUSCH, while Scell ​​only has HP PUSCH; Figure 3j As shown, PCcell contains temporally overlapping LP PUCCH and HP PUCCH, while Scell ​​only contains HPPUSCH; Figure 3k As shown, there are temporally overlapping LP PUSCH and HP PUCCH on PCcell, while only HP PUSCH is present on Scell.

[0182] In response to the above Figure 3i , Figure 3j and Figure 3k Regarding the temporal overlap, the terminal can process it according to the methods described in Embodiments 3 and 4 above.

[0187] Based on the above implementation method three, for Figure 3k :

[0188] Step 1: The terminal first processes the overlap between HP uplink channels, that is, the overlap between HP PUCCH and HP PUSCH, for example, multiplexing the UCI carried by HP PUCCH onto HP PUSCH (except SR); Step 2: The terminal transmits LP PUSCH on Pcell and transmits and multiplexes HP PUSCH with HP UCI on Scell ​​respectively.

[0191] Alternatively, the first step is to handle the overlap between LPPUSCH and LP PUCCH first, since LP PUSCH and PUCCH are in the same serving cell, for example, by multiplexing LP UCI onto LP PUSCH; the second step is for the terminal to transmit LP PUSCH multiplexed with LP UCI on Pcell and HP PUSCH on Scell ​​respectively.

[0196] Alternatively, the first step is as follows: Since HP PUCCH and LP PUSCH overlap on a serving cell, the terminal first processes the overlap between LPPUSCH and HP PUCCH, for example, multiplexing UCI onto LP PUSCH or multiplexing it onto HP PUSCH; the second step is as follows: The terminal transmits LP PUSCH on Pcell and HP PUSCH on Scell ​​respectively, wherein UCI is multiplexed on the channel of LP PUSCH or UCI is multiplexed on the channel of HP PUSCH.

[0197] The technical solution provided in this application embodiment, in the case of uplink channel time domain overlap, the terminal processes the overlap between uplink channels and transmits the processed uplink channels, thereby enabling the terminal to support simultaneous transmission of different types of uplink channels and multiplexing transmission between uplink channels of different priorities, improving the effectiveness of the communication system and enhancing the transmission performance of the terminal.

[0198] Please refer to Figure 4 , Figure 4 This is a flowchart of another uplink channel transmission method provided in an embodiment of this application. For example... Figure 4 As shown, the uplink channel transmission method includes the following steps:

[0199] Step 401: The network-side device receives the uplink channel transmitted by the terminal.

[0200] The uplink channel of the transmission includes at least one of the following:

[0201] Simultaneous transmission of different types of uplink channels;

[0202] Multiplex uplink channels with different priorities for transmission.

[0203] In this embodiment, the network-side device receives uplink channels transmitted by the terminal. The terminal processes overlapping uplink channels to enable simultaneous transmission of different types of uplink channels and / or multiplexing of uplink channels with different priorities. The specific implementation process can refer to the above. Figure 2 The descriptions in the method embodiments described herein will not be repeated in this embodiment.

[0204] In this embodiment, the uplink channel transmitted by the terminal is a combination of simultaneously transmitted uplink channels of different types and / or multiplexed uplink channels of different priorities. This allows the network-side device to simultaneously receive different types of uplink channels, such as simultaneously receiving PUSCH and PUCCH transmissions; or, the network-side device can receive multiplexed uplink channels of different priorities, such as multiplexing HP PUSCH transmissions of HP UCI; or, the network-side device can simultaneously receive different types of uplink channels and multiplexed uplink channels of different priorities. This improves the efficiency of the communication system's transmission and enhances the transmission performance between the network-side device and the terminal.

[0205] Optionally, the configuration of the network-side device includes at least one of the following:

[0206] Supports simultaneous transmission of PUCCH and PUSCH with the same priority on different carriers;

[0207] It supports simultaneous transmission of PUCCH and PUSCH with different priorities on different carriers;

[0208] Supports multiplexing of PUCCHs with the same priority;

[0209] Supports multiplexing of PUCCH and PUSCH with the same priority;

[0210] Supports multiplexing of PUCCH with different priorities and between PUCCH;

[0211] Supports multiplexing of PUCCH and PUSCH with different priorities.

[0212] It should be noted that if the network-side device is not configured to allow simultaneous transmission of PUCCH and PUSCH of the same priority on different carriers, it means that the terminal supports multiplexing of PUCCH and PUSCH of the same priority, or that the terminal supports multiplexing of PUCCH and PUSCH of the same priority by default. In other words, the network-side device does not need to directly configure the terminal to support multiplexing of PUCCH and PUSCH of the same priority. If the network-side device is configured to allow simultaneous transmission of PUCCH and PUSCH of the same priority on different carriers, it means that multiplexing of PUCCH and PUSCH of the same priority is not required.

[0213] As some optional implementation methods, the configuration of the network-side device can include various situations. For example, the configuration of the network-side device includes: supporting the simultaneous transmission of PUCCH and PUSCH of different priorities on different carriers, and supporting the multiplexing of PUCCH and PUSCH of the same priority; or, the configuration of the network-side device includes: supporting the simultaneous transmission of PUCCH and PUSCH of the same priority on different carriers, and supporting the multiplexing of PUCCH and PUSCH of different priorities, etc., etc., which will not be listed one by one in this embodiment.

[0214] It should be noted that the uplink channel transmission method provided in this application embodiment can be executed by an uplink channel transmission device, or by a control module within the uplink channel transmission device for executing the uplink channel transmission method. This application embodiment uses the execution of the uplink channel transmission method by an uplink channel transmission device as an example to illustrate the uplink channel transmission device provided in this application embodiment.

[0228] If there is an HP PUSCH in the serving cell where the LP PUSCH is located that overlaps with the LP PUSCH in the time domain, the transmission of the LP PUSCH that overlaps with the HP PUSCH in the time domain is cancelled first, and then the time domain overlap between PUCCHs of the same priority is processed.

[0248] Optionally, the processing module 501 is further configured to:

[0249] The overlap between high-priority uplink channels is processed and the transmission of LP PUSCH is cancelled. Specifically, when there is time-domain overlap between high-priority uplink channels of different types, the HP UCI carried by HP PUCCH is multiplexed onto HP PUSCH.

[0250] The overlap between low-priority uplink channels is handled. Specifically, when there is time-domain overlap between different types of low-priority uplink channels, the LP UCI carried by the LP PUCCH is multiplexed onto the LP PUSCH.
