UE IDLE AND INACTIVE MODE ENHANCEMENT WITH SIDELINK

Abstract:

Methods, systems, and devices for wireless communication are described. A connected mode UE may share reference signal configurations with an idle/inactive mode UE via a sidelink transmission. The connected mode UE may transmit a sidelink transmission including one or more reference signal configurations over a sidelink channel to an idle/inactive mode UE. The reference signal configuration may include reference signal resources that correspond to one or more beams that are tracked by the connected mode UE, such as an active downlink beam or beams adjacent to an active downlink beam. The idle/inactive mode UE may use the reference signal configuration to monitor for and receive one or more reference signals from the base station. In some examples, the connected mode UE may determine to transmit the sidelink transmission based on satisfaction of a trigger condition, such as a proximity of the idle/inactive mode UE to the connected mode UE.
