1. A method for power saving for a first wireless device, comprising:
determining a set of resources for communicating directly with a second wireless device, the set of resources including a first set of paging resources, wherein the first set of paging resources comprises one or more sub-channels and the one or more sub-channels are associated with a different sub-channel size than another sidelink sub-channel;
establishing a sidelink session with the second wireless device based on the set of resources;
entering a reduced power state;
monitoring, based on a paging schedule, the first set of paging resources;
receiving, from the second wireless device, a paging message, wherein the paging message includes an identifier for the first wireless device and an identifier for the second wireless device;
exiting the reduced power state based on the received paging message; and
monitoring, based on the received paging message, the set of resources.
