    Abstract: Some embodiments of this disclosure include apparatuses and methods for sidelink connection establishment design to support unicast and groupcast communication for NR V2X in a wireless communication system. The apparatuses and methods include at least generating an announcement of support for a unicast or a groupcast communication for a vehicle-to-everything (V2X) service, generating one or more connection establishment request messages for a secure link establishment to a second UE, to support a V2X communication to enable the V2X service, where the one or more connection establishment request message includes: a first connection establishment request message that is transmitted over a PC5-S interface, and a second connection establishment request message that is transmitted over a PC5-RRC interface. The apparatuses and methods further include at least processing a response message from the second UE that accepts or rejects the connection establishment request message for the secure link establishment.

    Abstract: Methods and systems are provided to indicate assistance information for radio access technologies to support interface selection for New Radio (NR) Vehicle-to-Everything (V2X) processes. An upper layer entity exchanges information with lower layer entity while the upper layer can continue to use the existing interface for V2X transmission until it is not able to use the current interface. The upper layer can be a V2X layer and the lower layer can be an Access Stratum (AS) layer. The upper layer can request availability information from the lower layer for other applicable interfaces. The upper layer then instructs the lower layer to provide assistance information for one or more applicable interface(s), depending on whether mapped to the ongoing service. In providing availability information, the lower layer can continuously measure criteria, such as channel conditions, to determine the availability of relevant interfaces and indicate the availability information to the upper layer.

    Abstract: A method for unicast communication over sidelink includes transmitting a direct communication request message from a source user equipment (UE) to one or more destination UEs. A direct communication response is received at the source UE from at least one of the one or more destination UEs, with the response including context information and a destination sidelink ID for the at least one UE. The context information of the at least one UE is stored in association with an ID pair comprising the destination sidelink ID and a source sidelink ID.
