Title:
RADIO LINK FAILURE IN SIDELINK RELAY
Document Type and Number:
WIPO Patent Application WO/2022/027548
Kind Code:
A1
Abstract:
Certain aspects of the present disclosure provide techniques for relay reselection triggering in sidelink relay systems. An example method for relay reselection triggering by a relay user equipment (UE) generally includes detecting a radio link failure (RLF) on at least one of a first link between the relay UE and a serving network entity or a second link between the relay UE and a remote UE and taking one or more actions, in response to the detection, to trigger relay reselection by the remote UE.
