1. A method performed by a first terminal, the method comprising:
deriving an offset based on an identifier of a second terminal; and
performing, at a target timing during a first duration within a sidelink discontinuous reception (DRX) cycle, a sidelink communication from the first terminal to the second terminal, the target timing being a timing after a time corresponding to the offset from a start timing of the first duration,
wherein a first timer is started from transmitting a negative feedback for a first sidelink transmission from the second terminal to the first terminal, the first timer indicating a duration including a first number of sidelink slots,
wherein a second timer is started when the first timer expires, the second timer indicating a second duration before a sidelink retransmission for the first sidelink transmission is received by the first terminal, and
wherein the method further comprises:
determining a third timer indicating a third duration after detecting the first sidelink transmission;
in accordance with a determination that the first terminal performs a second sidelink transmission before the third timer expires starting a fourth timer indicating a fourth duration: and
in accordance with a determination that the fourth timer expires, starting the second timer.
