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 computer-readable storage medium stores instructions for execution by one or more processors of a UE. The instructions configure the UE for small data transmission (SDT) in a 5G NR network and cause the UE to perform operations comprising detecting while in an RRC_Inactive state, a radio link failure during a first SDT of UL data to a base station. A secure key for a second SDT is generated based on the radio link failure. A configuration message including an indication of the second SDT is transmitted to the base station. A response message including a UL grant is received from the base station. The UL data is encoded for the second SDT using the secure key. The second SDT is performed using the UL grant while the UE is in the RRC_Inactive state.

The apparatus can include a memory to store the message.

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.

Abstract: A service device (e.g., a user equipment (UE), or other network component) can operate to generate sidelink communications with peer UE vehicle-to-vehicle devices based on PC5 channel to enable a peer-to-peer communication as part of PC5 vehicle-to-everything (V2X) communications. An admission control scheme or a congestion control scheme can be enabled by determining a configured mapping based on various criteria, including a priority of V2X services, V2X packet Quality of Service (QoS) indications per packet, or other criteria. A UE can determine whether a packet is authorized via the sidelink channel based on the configured mapping.

Abstract: An apparatus and system of validity conditions for pre-configured assistance data used during a long term evolution (LTE) Positioning Protocol (LPP) location procedure are described. The validity conditions are used to determine whether or not the assistance data remains valid for performing location measurements. The validity conditions may indicate that the assistance data is limited to a single positioning session or may be used for multiple sessions. In the latter case, the validity conditions may indicate geographic, timing, or number of sessions limitations. When the UE determines that the assistance data is no longer valid based on the validity conditions, the UE may request new assistance data prior to performing the measurements.
