Abstract: A service device (e.g., a user equipment (UE), or other network component) can operate generate sidelink communications with peer UE devices based on PC5 unicast link to enable a direct peer-to-peer communication as part of PC5 vehicle-to-everything (V2X) communications. Radio status link detection can be configured based on a keep alive (KA) coordination scheme via the PC5 unicast link to monitor a status of the PC5 unicast link. A KA timer can be configured based on the KA coordination scheme via the PC5 unicast link. The KA coordination scheme is configured to reduce redundant KA requests in the PC5 unicast link to coordinate the direct peer-to-peer communication across the PC5 unicast link.

Abstract: Apparatuses, systems, and methods for performing authorization revocation for unmanned aerial vehicles. A cellular network element of a cellular network may receive a request to revoke authorization of a wireless device that is an element in an unmanned aerial system. The cellular network element may provide an indication to the wireless device to disconnect from any other elements of the unmanned aerial system based at least in part on the request to revoke authorization.
