Wireless communication method and device

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.
