Abstract:
Methods, systems, and devices for sidelink wireless communications are described in which a user equipment (UE) engaged in sidelink communications may provide for radio link maintenance of the sidelink connection by initiating a maintenance procedure, such as a measurement procedure, when one or more conditions are detected. The one or more conditions may include a threshold time being exceeded since a data transmission via the sidelink connection, or a threshold time being exceeded since a successful reception of a sidelink transmission from another UE. An access stratum layer at the initiating UE may format a data packet in the absence of higher layer data to be transmitted via the sidelink connection to initiate the maintenance procedure.
