1. A method for wireless communication at a first user equipment (UE) of a group of UEs, comprising:
receiving configuration information for a sidelink discontinuous reception mode that corresponds to one or more active durations shared by the group of UEs and one or more inactive durations shared by the group of UEs, wherein the configuration information indicates a duration of a timer;
transmitting or receiving, to or from another UE of the group of UEs, a sidelink communication during an active duration of the one or more active durations;
initiating the timer based at least in part on transmitting or receiving the sidelink communication during the active duration;
monitoring a sidelink channel associated with the group of UEs after initiating the timer and for a time period based at least in part on the duration of the timer;
pausing or terminating the timer based at least in part on a value of the timer, at a beginning of a first inactive duration of the one or more inactive durations, being less than the duration of the timer; and
refraining from monitoring the sidelink channel during the first inactive duration.
