1. A data transmission method, comprising:
performing, by a first communication terminal, a clear channel assessment on a target resource, wherein the target resource is a target time domain resource corresponding to a part of second data transmission suspended or punctured by a second communication terminal, and the first communication terminal and the second communication terminal satisfy a transmission multiplexing condition; and
in response to determining that a channel is in an idle state, transmitting, by the first communication terminal, first data on the channel;
wherein the transmission multiplexing condition comprises the following:
a time domain resource corresponding to channel occupancy time (COT) of the first communication terminal overlaps a time domain resource corresponding to COT of the second communication terminal; or
wherein the transmission multiplexing condition further comprises the following:
a frequency domain resource corresponding to the COT of the first communication terminal overlaps a frequency domain resource corresponding to the COT of the second communication terminal;
wherein the first communication terminal and the second communication terminal are mobile terminals different from a base station, the COT of the first communication terminal is an occupied COT resource when the first communication terminal uses a scheduling-based resource or a scheduling-free resource for transmission, and the COT of the second communication terminal is an acquired COT after the second communication terminal performs the clear channel assessment.
