UE assisted fast transition between RRC states
Abstract:
UEs may want to switch to the RRC idle state or to the RRC inactive state sooner than the expiration of the timer or without having to wait for the network to release the RRC connection. Allowing the UE to increase the rate at which it transitions to RRC idle state or RRC inactive state may allow the UE to reduce power consumption, as well as reduce signaling resources. The apparatus determines a preference between a transition to an RRC inactive state or to an RRC idle state when an RRC connection is released. The apparatus sends, to a base station, an RRC state preference indication of the preference for transitioning upon release of the RRC connection from the RRC connected state to one of the RRC inactive state or to the RRC idle state.
