The method includes: determining, based on a first channel, whether to cancel transmission of a second channel. The first channel is determined based on at least one initial channel, and each initial channel of the at least one initial channel has a priority higher than a priority of the second channel. Whether to cancel the transmission of the second channel is determined based on the first channel, and the first channel is determined based on at least one initial channel. That is, the first channel that is used to determine whether to trigger to cancel transmission of the second channel is determined based on the at least one initial channel, which can ensure that the terminal device and the network device have consistent understandings of the first channel that is used to trigger whether to cancel transmission of the second channel. ## Claims ### Claim 1 A wireless communication method, performed by a terminal device, comprising: determining, based on a first channel, whether to cancel transmission of a second channel, wherein the first channel is determined after multiplexing of at least one initial channel, each of the at least one initial channel has a priority higher than a priority of the second channel, the first channel is a Physical Uplink Control CHannel (PUCCH) or a Physical Uplink Shared CHannel (PUSCH), and the second channel is a PUCCH or a PUSCH; wherein said determining, based on the first channel, whether to cancel the transmission of the second channel comprises: cancelling the transmission of the second channel in a case that the first channel and the second channel overlap; wherein the first channel and the second channel overlap, which comprises: the at least one initial channel and the second channel overlapping in a time domain. ### Claim 2 (depends on 1) The method according to claim 1, wherein the first channel and the second channel fully or partially overlap. ### Claim 3 (depends on 1) The method according to claim 1, wherein first scheduling information for triggering the first channel is not earlier than scheduling information corresponding to any one of the at least one initial channel other than an initial channel corresponding to the first scheduling information. ### Claim 4 (depends on 1) The method according to claim 1, wherein the first channel is scheduled directly by first scheduling information for triggering the first channel. ### Claim 5 (depends on 4) The method according to claim 4, wherein the at least one initial channel is transmitted by multiplexing. ### Claim 6 (depends on 1) The method according to claim 1, further comprising: maintaining cancellation of the transmission of the second channel in a case that a third channel and the second channel do not overlap. ### Claim 7 (depends on 6) The method according to claim 6, wherein scheduling information for triggering the third channel is not earlier than first scheduling information for triggering the first channel. ### Claim 8 (depends on 1) The method according to claim 1, wherein said determining, based on the first channel, whether to cancel the transmission of the second channel further comprises: transmitting the second channel in a case that the first channel and the second channel do not overlap. ### Claim 9 (depends on 1) The method according to claim 1, wherein the at least one initial channel comprises a channel indicated by scheduling information and/or a channel determined by the scheduling information. ### Claim 10 (depends on 9) The method according to claim 9, wherein the channel determined by the scheduling information comprises: a channel determined after multiplexing or overriding of a channel determined directly based on the scheduling information. ### Claim 11 (depends on 1) The method according to claim 1, wherein a time-domain position of first scheduling information for triggering the first channel is a time-domain position of the first scheduling information or a time-domain position determined based on the first channel. ### Claim 12 (depends on 11) The method according to claim 11, wherein the time-domain position of the first scheduling information is the time-domain position determined based on the first channel, and the first channel is a semi-static or semi-persistent configured uplink channel. ### Claim 13 A terminal device, comprising: a transceiver; a memory having a computer program stored thereon; and a processor configured to invoke and execute the computer program stored in the memory to perform: determining, based on a first channel, whether to cancel transmission of a second channel, wherein the first channel is determined after multiplexing of at least one initial channel, each of the at least one initial channel has a priority higher than a priority of the second channel, the first channel is a Physical Uplink Control CHannel (PUCCH) or a Physical Uplink Shared CHannel (PUSCH), and the second channel is a PUCCH or a PUSCH; said determining, based on the first channel, whether to cancel the transmission of the second channel comprises: cancelling the transmission of the second channel in a case that the first channel and the second channel overlap; wherein the first channel and the second channel overlap, which comprises: the at least one initial channel and the second channel overlapping in a time domain. ### Claim 14 (depends on 13) The terminal device according to claim 13, wherein the first channel and the second channel fully or partially overlap. ### Claim 15 (depends on 13) The terminal device according to claim 13, wherein first scheduling information for triggering the first channel is not earlier than scheduling information corresponding to any one of the at least one initial channel other than an initial channel corresponding to the first scheduling information. ### Claim 16 (depends on 13) The terminal device according to claim 13, wherein the first channel is scheduled directly by first scheduling information for triggering the first channel. ### Claim 17 (depends on 16) The terminal device according to claim 16, wherein the at least one initial channel is transmitted by multiplexing. ### Claim 18 (depends on 13) The terminal device according to claim 13, wherein the at least one initial channel comprises a channel indicated by scheduling information and/or a channel determined by the scheduling information. ### Claim 19 A network device, comprising: a transceiver; a memory having a computer program stored thereon; and a processor configured to invoke and execute the computer program stored in the memory to perform: determining, based on a first channel, whether to cancel transmission of a second channel, wherein the first channel is determined after multiplexing of at least one initial channel, each of the at least one initial channel has a priority higher than a priority of the second channel, the first channel is a Physical Uplink Control CHannel (PUCCH) or a Physical Uplink Shared CHannel (PUSCH), and the second channel is a PUCCH or a PUSCH; said determining, based on the first channel, whether to cancel the transmission of the second channel comprises: cancelling the transmission of the second channel in a case that the first channel and the second channel overlap; wherein the first channel and the second channel overlap, which comprises: the at least one initial channel and the second channel overlapping in a time domain. ### Claim 20 (depends on 19) The network device according to claim 19, wherein the first channel and the second channel fully or partially overlap.
