Abstract
A method and a terminal for determining a sidelink resource are disclosed. The method includes: determining a first sensing window, performing channel sensing in the first sensing window, and determining, in a transmission window, a sidelink resource for transmitting a sidelink transmission according to a result of the channel sensing, wherein the transmission window is used for transmitting the sidelink transmission. The disclosure determines a range of channel sensing, so that the power consumption of a UE monitoring a sidelink is reduced.
