1. A method for power saving for a wireless device, comprising:
determining, by a first wireless device, a set of sidelink resources for communicating directly with a second wireless device, wherein determining the set of sidelink resources comprises:
sensing at least a portion of the set of sidelink resources to determine a set of candidate sidelink resources; and
adjusting the set of candidate sidelink resources based on discontinuous reception (DRX) configuration information of the second wireless device, wherein adjusting the set of candidate sidelink resources comprises excluding candidate sidelink resources based on a comparison of the candidate sidelink resources in the set of candidate sidelink resources and a DRX-on duration time indicated in the DRX configuration information of the second wireless device;
receiving sidelink coordination information, the sidelink coordination information including the DRX configuration information of the second wireless device;
selecting, from the set of adjusted candidate sidelink resources, a sidelink resource; and
transmitting sidelink data to the second wireless device on the selected sidelink resource.
