A first user equipment able to communicate with other user equipments via sidelink communications determines a procedure to use for selecting a host of a coordination of sidelink discontinuous reception when receiving a connection request from a second user equipment, and based on whether a requirement for a flow corresponding to the connection request meets a threshold. The first user equipment then performs sidelink discontinuous reception coordination between the first and second user equipment based on the determined host. The first user equipment sends configuration a second user equipment to use for discontinuous reception for the sidelink communications, or it requests help from a second user equipment to perform alignment of discontinuous reception for the sidelink communications.
