Abstract:
1. A method of wireless communication, comprising: detecting, at a first user equipment (UE) relay node, a UE; determining whether an active second UE relay node is present in response to detecting the UE; controlling, at the first UE relay node, a transition of an access link from a dormant state to an active state when the UE is detected and when the active second UE relay node is not present; and managing, at the first UE relay note in response to the transition, a connection on a backhaul link to enter a dormant state for the backhaul link by at least decreasing a duty cycle of network timing and frequency tracking, decreasing a duty cycle of low power node access opportunity to a base station, or a combination thereof, and the connection on the backhaul link transitioning to an active state, based on a triggering event, by accessing the base station and establishing signaling and data radio bearers.
