SIDELINK DRX AND STANDALONE SIDELINK BEAM FAILURE DETECTION AND RECOVERY

Abstract:

Certain aspects of the present disclosure provide techniques for standalone sidelink beam failure recovery. In certain aspects, a method performed by a first user equipment may generally include communicating, while operating in a sidelink discontinuous reception (DRX) mode, with a second UE on a first communications link between the first UE and the second UE; transmitting, during an awake state of the sidelink DRX mode, at least one beam failure detection reference signal of a plurality of beam failure detection reference signals associated with the first communications link, wherein a periodicity of the awake state of the sidelink DRX mode is based on a periodicity for transmitting the plurality of beam failure detection reference signals; and detecting that the first communications link between the first UE and the second UE has failed based on the at least one beam failure detection reference signal.
