摘要： A method for changing layer 2 (L2) identifiers (ID)s during an ongoing vehicle-to-everything session between a source wireless transmit/receive unit (WTRU) and a peer WTRU includes communicating between the source and a peer WTRUs based on existing L2 IDs and an existing session ID. On a condition that a trigger event occurs, the source WTRU and the peer WTRU each generate new L2 IDs as well as respective portions of a new session ID. The new L2 IDs are subsequently used along with the new session ID to increase privacy of communication between the source WTRU and the peer WTRU.

摘要： Methods and apparatuses are described herein for dynamic PC5 communication adaptation. For example, a UE may receive, from a vehicle-to-everything control function (V2X CF) or a vehicle-to-everything application server (V2X AS), a V2X provisioning message that includes a first transmission profile and determine, based on the first transmission profile, a first range to configure PC5 communication of a plurality of UEs associated with the V2X platoon. When a number of UEs joining the V2X platoon exceeds a certain threshold, the UE may transmit, to the V2X CF or the V2X AS, a modification request message requesting a second transmission profile. The UE may receive, from the V2X CF or the V2X AS, a modification response message that includes the second transmission profile and determine, based on the second transmission profile, a second range to reconfigure the PC5 communication of the plurality of UEs associated with the V2X platoon.

摘要： Methods and apparatuses are described herein for proximity-based services (ProSe) service-based discovery. For example, a service utilizing-wireless transmit/receive unit (SU-WTRU) may be provisioned with a type of discovery on a per-service basis and a security credential on a per-service basis. The SU-WTRU may transmit (315) a PC5 discovery message with the type of discovery and a first security element that is generated based on the security credential. The WTRU may then receive (325), from a service providing-wireless transmit/receive unit (SP-WTRU), a PC5 discovery response message that includes a second security element and a service identity associated with a service that the SP-WTRU provides. On a condition that the second security element is verified based on the provisioned security credential, the SU-WTRU may authorize (330) the SP-WTRU to establish a PC5 communication link with the SP-WTRU.

摘要： Mobile device-to-mobile device discovery may be performed via a relay device (e.g., wireless transmit and receive unit (WTRU)), which may send a discovery request (e.g., including service ID, relay capability indication, and relay WTRU ID) to a ProSe server. A discovery response may include a (e.g., ProSe) relay service broadcast code and discovery filter (e.g., corresponding to service ID for a service broadcast by a service provider WTRU). The relay WTRU may use the discovery filter to listen for a ProSe code broadcast by a service provider WTRU. The relay WTRU may determine a received ProSe code matches the discovery filter. The relay WTRU may broadcast the relay service broadcast code based on the match. The service broadcast code broadcast may be intended for receipt by a service utilizing WTRU, which may utilize the relay WTRU to join/receive a service from a service provider WTRU.
