[0047] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present application.

[0048] Before describing the embodiments of the present application, a brief description of the related contents is given.

[0049] In the 3rd Generation Partnership Project (3GPP) version 15 (Rel-15) for the New Radio (NR) system, it is clarified that overlapping multiple PUCCHs or overlapping multiple physical uplink control channels (PUCCH) and physical uplink shared channels (PUSCH) can only be multiplexed in one channel for transmission when the multiplexing timing relationship is met; otherwise, the terminal device will determine it as an abnormal situation. Among them, the timing relationship is to ensure that the terminal device has enough time to determine whether the information carried by different uplink channels needs to be multiplexed, and the time required for uplink control information (UCI) cascading and encoding during multiplexing transmission. 3GPP implements UCI multiplexing transmission through the following methods:

[0050] A group of non-overlapping PUCCH resources is determined in a time slot by the following method.

[0051] 1. Set a set Q, which includes all PUCCHs to be transmitted in the time slot (i.e., the network device indicates to the terminal device that it needs to be transmitted);

[0052] 2. Set PUCCH resource A. PUCCH resource A is the PUCCH with the earliest start time in set Q. If there are multiple PUCCH resources with the same start time, the PUCCH resource with the longest duration is selected. If the start time and duration of the PUCCH resources are the same, select one PUCCH resource from the PUCCH resources with the same start time and duration.

[0053] 3. The PUCCH resources in set Q that overlap with PUCCH resource A constitute set X;

[0054] 4. Determine a PUCCH resource B based on PUCCH resource A and PUCCH resources in set X. PUCCH resource B is used to multiplex and transmit the UCI carried by PUCCH resource A and PUCCH resources in set X. In set Q, PUCCH resource B is used to replace PUCCH resource A and PUCCH resources in set X;

[0055] 5. If after step 4, there are overlapping PUCCH resources in set Q, clear set X and repeat steps 2 to 4 until there are no overlapping PUCCH resources in set Q.

[0056] Finally, if a PUCCH resource in the set Q of non-overlapping PUCCH resources overlaps with a PUSCH resource, the UCI information carried by the PUCCH resource is multiplexed onto the PUSCH resource for transmission; otherwise, the PUCCH resource is used to transmit the UCI.

[0057] An optional process for multiplexing transmission, such as Figure 1 As shown in the figure, the PUCCHs to be transmitted in a time slot are PUCCH 1, PUCCH 2 and PUCCH 3; PUCCH 1 overlaps with PUCCH 2, and PUCCH 2 overlaps with PUCCH 3. PUCCH B obtained based on PUCCH 1 and PUCCH 2 is used to multiplex and transmit the UCI carried by PUCCH 1 and PUCCH 2. PUCCH B overlaps with PUCCH 3, and after performing the above steps 2 to 4 again, PUCCH B' is obtained, that is, PUCCH resource B' is included in set Q. All UCI carried by PUCCH 1, PUCCH 2 and PUCCH 3 are multiplexed and transmitted in PUCCH resource B'.

[0058] In Rel-16, in order to better support Ultra-Reliable Low Latency (URLLC) services. The physical channel can be configured with 2-level priority (2-level priority), that is, high priority or low priority. Usually URLLC services will use high-priority channels for transmission. If there are multiple uplink channels of different priorities overlapping, for the low-priority channels, the terminal device uses the working mechanism determined by the above-mentioned Rel-15 to determine the multiplexed channel. If the high-priority uplink channel overlaps with the low-priority uplink channel (multiplexed channel or non-multiplexed channel), the transmission of the low-priority channel is cancelled and only the high-priority channel is transmitted. If multiple high-priority channels overlap, the working mechanism determined by Rel-15 is used to determine the multiplexed channel, and the reliability and latency requirements of the high-priority channel are guaranteed by sacrificing the transmission efficiency of the low-priority channel.

[0059] In Rel-17, the aim is to minimize the impact of high-priority channel transmission on low-priority channel transmission. Therefore, it is proposed to support the multiplexing of information of different priorities in one uplink channel for transmission. However, in the current discussion, the multiplexing transmission of information of different priorities is not applicable to all uplink control information. The specific supported multiplexing transmission combinations include: High Priority (HP) HARQ feedback information (ACK / NACK) and low priority (LP) hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) feedback information are multiplexed and transmitted through PUCCH; LP HARQ feedback information and HP scheduling request (Scheduling Requst, SR) are multiplexed and transmitted through PUCCH; LP HARQ feedback information, HP HARQ feedback information and HP SR are multiplexed and transmitted through PUCCH.

[0060] Another optional process for multiplexing transmission, such as Figure 2 As shown, PUCCH 1 is used to carry LP HARQ feedback information, PUCCH 2 is used to carry low priority channel state information (CSI), and PUCCH 3 is used to carry HP HARQ feedback information. If a set of non-overlapping PUCCH resources in a time slot or sub-time slot is determined according to the mechanism determined in Rel-15, that is, set Q, then PUCCH resource B' will be obtained for transmitting multiplexing information, that is, Figure 1 The process shown. However, the HP HARQ feedback information cannot be multiplexed with the CSI for transmission. At this time, the PUCCH resource B' obtained multiplexes the LP HARQ feedback information and the HP HARQ feedback information. However, PUCCH 1 and PUCCH 3 do not overlap and can be transmitted independently.

[0061] Compared with independent transmission, multiplexed transmission is less efficient. In order to ensure the reliability of high-priority UCI, low-priority UCI in multiplexed transmission may take up more resources to transmit in order to achieve the same reliability as high-priority UCI. In addition, multiplexed transmission will introduce additional delays required for UCI concatenation and encoding.

[0077] An optional processing flow of the channel determination method provided in the embodiment of the present application is as follows: Figure 4 As shown, at least the following steps may be included:

[0078] Step S201, the terminal device determines a first uplink control channel resource set, the first uplink control channel resource set does not include a first uplink control channel resource within a first time unit, the first uplink control channel resource set includes a second uplink control channel resource within the first time unit, wherein the first uplink control channel resource is used to transmit a first UCI, the second uplink control channel resource is used to transmit a second UCI, the priority of the second UCI is higher than the first UCI, and the first UCI satisfies a first agreed condition.

[0079] In some embodiments, the terminal device is configured to transmit multiple PUCCHs in the first time unit, wherein at least two of the multiple PUCCHs overlap. As an example, the network device configures the terminal device to transmit two or more PUCCHs in the first time unit, and at least two of the multiple PUCCHs transmitted by the terminal device in the first time unit overlap. As an example, PUCCH overlap may be that PUCCH resources overlap in the time domain.

[0080] In some embodiments, the first time unit is a time unit corresponding to the second UCI, or the first time unit is a time unit corresponding to the first UCI, or the first time unit is the shortest time unit between a time unit corresponding to the first UCI and a time unit corresponding to the second UCI, or the first time unit is the longest time unit between a time unit corresponding to the first UCI and a time unit corresponding to the second UCI.

[0081] As an example, the time unit corresponding to the first UCI may be the time unit corresponding to the PUCCH used to transmit the first UCI; the time unit corresponding to the second UCI may be the time unit corresponding to the PUCCH used to transmit the second UCI; the shortest time unit may be the time unit including the least number of time domain symbols; the longest time unit may be the time unit including the largest number of time domain symbols. For example, the number of time domain symbols included in the time unit corresponding to the first UCI is 6, and the number of time domain symbols included in the time unit corresponding to the second UCI is 8. If the first time unit is the shortest time unit between the time unit corresponding to the first UCI and the time unit corresponding to the second UCI, then the first time unit is the time unit corresponding to the first UCI; if the first time unit is the longest time unit between the time unit corresponding to the first UCI and the time unit corresponding to the second UCI, then the first time unit is the time unit corresponding to the second UCI.

[0082] In some embodiments, the first agreed condition may include: the first UCI and the second UCI cannot be multiplexed for transmission. As an example, the first UCI and the second UCI cannot be multiplexed for transmission may be that the first UCI and the second UCI cannot be transmitted on the same uplink channel.

[0083] In some embodiments, the first agreed condition may be an agreed condition for information carried by the first UCI and information carried by the second UCI. As an example, the information carried by the first UCI may be information carried or indicated by the first UCI, and the information carried by the second UCI may be information carried or indicated by the second UCI.

[0084] As an example, the first UCI satisfying the first agreed condition may include LP CSI and / or LP SR, and the second UCI satisfying the first agreed condition may include HP HARQ ACK / NACK. The CSI transmitted through the PUCCH may be defaulted to LP CSI.

[0085] As another example, the first UCI satisfying the first agreed condition may include LP CSI, and the second UCI satisfying the first agreed condition may include HP SR. The CSI transmitted through the PUCCH may be LP CSI by default.

[0086] In some embodiments, the processing flow of determining the first uplink control channel resource set by the terminal device at least includes: the terminal device determines the second uplink control channel resource set, the second uplink control channel resource set includes all uplink control channel resources in the first time unit; removes the first uplink control channel resource in the second uplink control channel resource set to obtain the first uplink control channel resource set. As an example, the first uplink control channel resource set is composed of uplink control channel resources in the second uplink control channel resource set except the first uplink control channel resource, and the second uplink control channel resource set includes all uplink control channel resources in the first time unit.

[0087] In some embodiments, if the first uplink control channel resource in the second uplink control channel resource set is removed, the terminal device discards (drops) the first PUCCH, or cancels (cancels) the first PUCCH, or skips (skips) the first PUCCH; or discards the first UCI carried by the first PUCCH, or cancels the first UCI, or skips the first UCI.

[0088] In some embodiments, the first time unit may be a frame, a subframe, a time slot, a subslot, or at least one symbol, etc.

[0089] In some embodiments, if the first PUCCH overlaps with the third PUCCH, the terminal device discards the first PUCCH. In other embodiments, if the first PUCCH overlaps with the third PUCCH, the terminal device transmits the third UCI carried by the third PUCCH; the third PUCCH may be one of the PUCCH resources overlapping within the first time unit determined based on the first PUCCH resource set. As an example, the overlap of the first PUCCH and the third PUCCH may be that the first PUCCH resource and the third PUCCH resource overlap in the time domain.

[0090] Step S203: The terminal device determines non-overlapping uplink control channel resources within the first time unit based on the first uplink control channel resource set.

[0091] In some embodiments, the process of determining, by the terminal device based on the first uplink control channel resource set, non-overlapping uplink control channel resources within the first time unit may at least include:

[0092] 1) Set PUCCH resource A, where PUCCH resource A is the PUCCH with the earliest start time in the first uplink control channel resource set. If the PUCCH resource with the earliest start time in the first PUCCH resource set includes two or more PUCCH resources, then select the PUCCH resource with the earliest start time and the longest duration as PUCCH resource A; if the PUCCH resource with the earliest start time and the longest duration includes two or two PUCCH resources, then select one PUCCH resource from multiple PUCCH resources with the earliest start time and the longest duration as PUCCH resource A.

[0093] 2) The PUCCH resources overlapping with the PUCCH resource A in the first PUCCH resource set constitute a PUCCH resource set X.

[0094] 3) A PUCCH resource B is determined according to PUCCH resource A and PUCCH resource set X, and PUCCH resource B is used to transmit all UCIs carried by PUCCH resource A and PUCCH resource set X. In the first PUCCH resource set, PUCCH resource A and PUCCH resource set X are replaced by PUCCH resource B.

[0095] 4) If there are still overlapping PUCCH resources in the first PUCCH resource set after executing 3), clear the PUCCH resource set X and repeat 1) to 3) until there are no overlapping PUCCH resources in the first PUCCH resource set.

[0096] It should be noted that the above 1) to 4) are only used to make the description clearer, and do not limit the terminal device to determine the execution order of non-overlapping uplink control channel resources within the first time unit based on the first uplink control channel resource set. The execution order should be determined by its function and internal logic.

[0097] Another optional processing flow of the channel determination method provided in the embodiment of the present application is as follows: Figure 5 As shown, at least the following steps may be included:

[0098] Step S301, the network device determines a first uplink control channel resource set, the first uplink control channel resource set does not include a first uplink control channel resource within a first time unit, the first uplink control channel resource set includes a second uplink control channel resource within the first time unit, wherein the first uplink control channel resource is used to transmit a first uplink control information UCI, the second uplink control channel resource is used to transmit a second UCI, the priority of the second UCI is higher than the first UCI, and the first UCI satisfies a first agreed condition.

[0099] In some embodiments, the description of the first uplink control channel resource set, the first agreed condition, the first UCI and the second UCI is the same as the description of the first uplink control channel resource set, the first agreed condition, the first UCI and the second UCI in the above step S201, and is not repeated here.

[0100] Step S303: The network device determines non-overlapping uplink control channel resources within the first time unit based on the first uplink control channel resource set.

[0101] In some embodiments, the processing process of the network device determining the non-overlapping uplink control channel resources within the first time unit based on the first uplink control channel resource set is the same as the processing process of the terminal device determining the non-overlapping uplink control channel resources within the first time unit based on the first uplink control channel resource set in the above step S203, and will not be repeated here. The difference between step S303 and step S203 is that the execution subject in step S303 is the network device, and the execution subject in step S203 is the terminal device.

[0102] by Figure 2 Taking the multiplexing transmission shown in FIG. 1 as an example, PUCCH 1 is used to carry LP HARQ feedback information, PUCCH 2 is used to carry CSI information, and PUCCH 3 is used to carry HP HARQ feedback information. The terminal device and / or the network device first determines that the second PUCCH resource set includes PUCCH 1, PUCCH 2, and PUCCH 3. Since CSI and HP HARQ feedback information cannot be multiplexed and transmitted on the same PUCCH, PUCCH 2 is removed from the second PUCCH resource set to obtain the first PUCCH resource set; the schematic diagram of the first PUCCH resource set is as shown in FIG. Figure 6 As shown, the first PUCCH resource set includes PUCCH 1 and PUCCH 3. Since PUCCH 1 and PUCCH 3 do not overlap, there are no overlapping PUCCH channels in the first PUCCH resource set. At this time, PUCCH 1 and PUCCH 3 can be transmitted independently.

[0103] In some embodiments, Figure 6 For the first PUCCH resource set, if PUCCH1 overlaps with PUSCH, the UCI carried by PUCCH1 can be multiplexed to the PUSCH overlapping with PUCCH1 for transmission; similarly, if PUCCH3 overlaps with PUSCH, the UCI carried by PUCCH3 can be multiplexed to the PUSCH overlapping with PUCCH3 for transmission.

[0104] The channel determination method provided in the embodiment of the present application obtains a first PUCCH resource set by removing the first PUCCH that cannot be multiplexed and transmitted with the PDCCH carrying high-priority UCI on an uplink channel within a time unit; at least two PUCCH resources in the first PUCCH resource set can be multiplexed and transmitted on an uplink channel, and independent PUCCH resources in the first PUCCH resource set can be transmitted on independent uplink channels. In this way, the efficiency of PUCCH resource transmission can be improved, unnecessary multiplexing processing can be avoided as much as possible, and the terminal device is simple to implement.

[0105] An optional processing flow of the channel transmission method provided in the embodiment of the present application is as follows: Figure 7 As shown, at least the following steps may be included:

[0106] Step S401: The terminal device receives configuration information sent by the network device.

[0107] In some embodiments, the terminal device is configured to transmit multiple PUCCHs within a second time unit, wherein the multiple PUCCHs include a fourth PUCCH for transmitting a fourth UCI and a fifth PUCCH for transmitting a fifth UCI, the priority of the fifth UCI is higher than the priority of the fourth UCI, and at least two of the multiple PUCCHs overlap.

[0108] In some embodiments, the second time unit may be a frame, a subframe, a time slot, a subslot, or at least one symbol, etc.

[0109] In some embodiments, the terminal device is configured to transmit multiple PUCCHs within the second time unit by the network device sending configuration information to the terminal device, where the configuration information is used to configure the terminal device to transmit at least two PUCCHs within the second time unit.

[0110] In some embodiments, the network device configures the terminal device to transmit two or more PUCCHs in the second time unit, and at least two of the multiple PUCCHs transmitted by the terminal device in the second time unit overlap. As an example, PUCCH overlap may be that PUCCH resources overlap in the time domain.

[0111] In some embodiments, the information carried by the fourth UCI may be information carried by or indicated by the fourth UCI, and the information carried by the fifth UCI may be information carried by or indicated by the fifth UCI.

[0112] Step S403: If the second agreed condition is met, the terminal device transmits the fourth UCI and the fifth UCI through one channel within the second time unit.

[0113] In some embodiments, the second agreed condition is an agreed condition for information carried by the fourth UCI and information carried by the fifth UCI.

[0114] As an example, the fourth UCI satisfying the second prescribed condition may include LP HARQ ACK / NACK, and the fifth UCI satisfying the second prescribed condition may include HP HARQ ACK / NACK.

[0115] As another example, the fourth UCI satisfying the second prescribed condition may include LP HARQ ACK / NACK, and the fifth UCI satisfying the second prescribed condition may include HP SR.

[0116] In some embodiments, if the fourth PUCCH overlaps with the fifth PUCCH and satisfies the second agreed condition described in step S401, the fourth UCI and the fifth UCI may be multiplexed and transmitted in one uplink channel.

[0117] In some embodiments, the channel transmission method may further include:

[0118] Step S405: If the fourth UCI satisfies the third agreed condition, the terminal device discards the fifth UCI; or, if the fourth UCI satisfies the third agreed condition, the terminal device discards the fifth uplink control channel.

[0119] In some embodiments, the third agreed condition is an agreed condition for information carried by the fourth UCI and information carried by the fifth UCI.

[0120] As an example, the information carried by the fourth UCI may be information carried by or indicated by the fourth UCI, and the information carried by the fifth UCI may be information carried by or indicated by the fifth UCI.

[0121] In some embodiments, the third agreed condition may include at least one of the following: the second agreed condition is not satisfied; the fifth UCI includes: HP HARQ ACK / NACK, and the fourth UCI includes: CSI and / or LP SR.

[0122] As an example, if the fourth UCI and the fifth UCI do not satisfy the following two combinations 1) and 2), the second agreed condition is not satisfied: 1) the fourth UCI is LP HARQ ACK / NACK, and the fifth UCI is HP HARQ ACK / NACK. 2) the fourth UCI is LP HARQ ACK / NACK, and the fifth UCI is HP SR. In this scenario, the terminal device discards the fifth UCI, cancels the fifth UCI, or ignores the fifth UCI; or the terminal device discards the fifth PUCCH, cancels the fifth PUCCH, or ignores the fifth PUCCH.

[0123] As another example, if the fifth UCI is HP HARQ ACK / NACK and the fourth UCI is low priority CSI and / or LP SR, the terminal device discards the fifth UCI, cancels the fifth UCI, or ignores the fifth UCI; or, the terminal device discards the fifth PUCCH, cancels the fifth PUCCH, or ignores the fifth PUCCH.

[0124] As another example, if the fifth UCI is HP SR and the fourth UCI is low priority CSI, the terminal device discards the fifth UCI, or cancels the fifth UCI, or ignores the fifth UCI; or, the terminal device discards the fifth PUCCH, or cancels the fifth PUCCH, or ignores the fifth PUCCH.

[0125] Among them, the CSI transmitted through the PUCCH can be defaulted to low priority CSI.

[0126] In some embodiments, the second time unit is a time unit corresponding to the fifth UCI; or, the second time unit is a time unit corresponding to the fourth UCI; or, the second time unit is the shortest time unit between the time unit corresponding to the fourth UCI and the time unit corresponding to the fifth UCI; or, the second time unit is the longest time unit between the time unit corresponding to the fourth UCI and the time unit corresponding to the fifth UCI.

[0127] As an example, the time unit corresponding to the fourth UCI may be the time unit corresponding to the PUCCH used to transmit the fourth UCI; the time unit corresponding to the fifth UCI may be the time unit corresponding to the PUCCH used to transmit the fifth UCI; the shortest time unit may be the time unit including the least number of time domain symbols; the longest time unit may be the time unit including the largest number of time domain symbols. For example, the number of time domain symbols included in the time unit corresponding to the fourth UCI is 10, and the number of time domain symbols included in the time unit corresponding to the fifth UCI is 12. If the second time unit is the shortest time unit between the time unit corresponding to the fourth UCI and the time unit corresponding to the fifth UCI, then the second time unit is the time unit corresponding to the fourth UCI; if the second time unit is the longest time unit between the time unit corresponding to the fourth UCI and the time unit corresponding to the fifth UCI, then the second time unit is the time unit corresponding to the fifth UCI.

[0128] Another optional processing flow of the channel transmission method provided in the embodiment of the present application is as follows: Figure 8 As shown, at least the following steps may be included:

[0129] Step S501: The network device configures the terminal device to transmit multiple uplink control channels within a second time unit; the multiple PUCCHs include a fourth uplink control channel for transmitting a fourth UCI and a fifth uplink control channel for transmitting a fifth UCI, the priority of the fifth UCI is higher than the priority of the fourth UCI, and at least two PUCCHs in the multiple uplink control channels overlap. As an example, the multiple PUCCHs include at least two PUCCHs with different priorities, and the PUCCH overlap may be that the PUCCH resources overlap in the time domain.

[0130] In some embodiments, the network device sends configuration information to the terminal device, where the configuration information is used to configure the terminal device to transmit at least two PUCCHs within a second time unit.

[0131] In some embodiments, the description of the fourth UCI and the fifth UCI is the same as the description of the fourth UCI and the fifth UCI in the above step S401 , and is not repeated here.

[0132] Step S503: If the second agreed condition is met, the network device receives the fourth UCI and the fifth UCI through one channel within the second time unit.

[0133] In some embodiments, the description of the second agreed condition is the same as the description of the second agreed condition in the above step S403, and is not repeated here.

[0134] In some embodiments, if the fourth UCI satisfies the third agreed condition, the terminal device discards the fifth UCI; or, if the fourth UCI satisfies the third agreed condition, the terminal device discards the fifth uplink control channel. In this scenario, the network device does not receive the fifth UCI and / or the fifth uplink control channel.

[0135] In some embodiments, the third agreed condition is an agreed condition for information carried by the fourth UCI and information carried by the fifth UCI.

[0136] As an example, the information carried by the fourth UCI may be information carried by or indicated by the fourth UCI, and the information carried by the fifth UCI may be information carried by or indicated by the fifth UCI.

[0137] In some embodiments, the third agreed condition may include at least one of the following: the second agreed condition is not satisfied; the fifth UCI includes: HP HARQ ACK / NACK, and the fourth UCI includes: CSI and / or LP SR.

[0138] As an example, if the fourth UCI and the fifth UCI do not satisfy the following two combinations 1) and 2), the second agreed condition is not satisfied: 1) the fourth UCI is LP HARQ ACK / NACK, and the fifth UCI is HP HARQ ACK / NACK. 2) the fourth UCI is LP HARQ ACK / NACK, and the fifth UCI is HP SR. In this scenario, the terminal device discards the fifth UCI, cancels the fifth UCI, or ignores the fifth UCI; or the terminal device discards the fifth PUCCH, cancels the fifth PUCCH, or ignores the fifth PUCCH.

[0139] As another example, if the fifth UCI is HP HARQ ACK / NACK and the fourth UCI is low priority CSI and / or LP SR, the terminal device discards the fifth UCI, cancels the fifth UCI, or ignores the fifth UCI; or, the terminal device discards the fifth PUCCH, cancels the fifth PUCCH, or ignores the fifth PUCCH.

[0140] As another example, if the fifth UCI is HP SR and the fourth UCI is low priority CSI, the terminal device discards the fifth UCI, or cancels the fifth UCI, or ignores the fifth UCI; or, the terminal device discards the fifth PUCCH, or cancels the fifth PUCCH, or ignores the fifth PUCCH.

[0141] Among them, the CSI transmitted through the PUCCH can be defaulted to low priority CSI.

[0142] In some embodiments, the second time unit is a time unit corresponding to the fifth UCI; or, the second time unit is a time unit corresponding to the fourth UCI; or, the second time unit is the shortest time unit between the time unit corresponding to the fourth UCI and the time unit corresponding to the fifth UCI; or, the second time unit is the longest time unit between the time unit corresponding to the fourth UCI and the time unit corresponding to the fifth UCI.

[0143] As an example, the time unit corresponding to the fourth UCI may be the time unit corresponding to the PUCCH used to transmit the fourth UCI; the time unit corresponding to the fifth UCI may be the time unit corresponding to the PUCCH used to transmit the fifth UCI; the shortest time unit may be the time unit including the least number of time domain symbols; the longest time unit may be the time unit including the largest number of time domain symbols. For example, the number of time domain symbols included in the time unit corresponding to the fourth UCI is 10, and the number of time domain symbols included in the time unit corresponding to the fifth UCI is 12. If the second time unit is the shortest time unit between the time unit corresponding to the fourth UCI and the time unit corresponding to the fifth UCI, then the second time unit is the time unit corresponding to the fourth UCI; if the second time unit is the longest time unit between the time unit corresponding to the fourth UCI and the time unit corresponding to the fifth UCI, then the second time unit is the time unit corresponding to the fifth UCI.

[0144] by Fig. 9 Taking another multiplexed transmission as an example, PUCCH 1 is used to carry LP HARQ feedback information, PUCCH 2 is used to carry HP SR, and PUCCH 3 is used to carry HP HARQ feedback information. Since HP SR can be multiplexed with LP HARQ feedback information for transmission, LP HARQ feedback information can be multiplexed with HP HARQ feedback information for transmission. Therefore, the HP SR, HP HARQ feedback information, and LP HARQ feedback information can be multiplexed and transmitted through one channel within the second time unit.

[0145] The channel transmission method provided in the embodiment of the present application configures multiple PUCCHs within a time period for the terminal device as PUCCHs that meet the second agreed condition through the network device, so that the multiple PUCCHs configured by the network device can be multiplexed and transmitted on an uplink channel. In this way, the efficiency of PUCCH resource transmission can be improved, the multiplexing transmission mechanism can be simplified, and the complexity of terminal device implementation can be reduced.

[0146] by Figure 2 Taking the multiplexed transmission shown in FIG. 1 as an example, the second time unit is 1 time slot, PUCCH 1 is used to carry LP HARQ feedback information, PUCCH 2 is used to carry CSI, and PUCCH 3 is used to carry HP HARQ feedback information. Since CSI cannot be multiplexed with HP HARQ feedback information for transmission, PUCCH 2 is cancelled or CSI is discarded in the second time unit.

[0147] The channel transmission method provided in the embodiment of the present application configures multiple PUCCHs within a time period for the terminal device as PUCCHs that meet the third agreed condition through the network device, then cancels the transmission of the PUCCH carrying the low-priority UCI and only transmits the high-priority UCI, thereby simplifying the implementation complexity of the terminal.
