    Abstract: A discoverer user equipment sends a discovery announcement to a discoveree user equipment via a sidelink service. The announcement includes criteria for a service sought by discoverer. The discoveree assesses the announcement and may respond to the discoverer. The discovery announcement may be a target search discovery announcement or a self-advertisement discovery announcement, and may be unicast, groupcast, or broadcast. The discoverer and discoveree may perform synchronization in support of V2X sidelink communication and may collect driving information pertaining to vehicles associated with the discoverer and discoveree, respectively, such as driving intention, positioning, and environment information. The discoverer may request an authorization for the discovery announcement, and the request may include the driving information. The information in the announcement and the response may include discoverer and discoveree service, platform, and radio capabilities, source identifiers, driving information, radio measurements, group identifiers, and protocol configuration parameters.

    Abstract: The exchange of resource allocation assistance information between a requester User Equipment (UE) and an assistant UE allows the requester to make better resource allocation decisions. The assistance information may include a blacklist, a whitelist, resource allocation information, a candidate resource set, and measurement information, for example. Both UEs may have an assistance configuration to assist in the exchange of resource allocation assistance information, that may be obtained from a third apparatus, such as a base station. The configuration may include information related to when to trigger assistance, identities of UEs, and types of assistance information, for example. The requester may, based on the assistance information received, modify a candidate resource set at a Medium Access Control (MAC) layer. The requester may, at the MAC layer, determine a configured sidelink grant for a selected destination using assistance information targeting this destination.

    Abstract: A Sidelink AS group management function is disclosed for a UE to discover group members and organize them into AS layer sub-groups based on the AS layer group context information. A centralized Sidelink AS group management is disclosed that the Sidelink AS Group Manager discovers group members and organizes them into AS layer sub-groups for a UE. A Subgroup formation and configuration procedure is disclosed that SL AS Group Manager organizes the ULG into AS layer sub-groups, configures UE-to-UE relays for each UE in the ULG and sends the AS group management information to the UE. A distributed Sidelink AS group management method is disclosed that each UE discovers its group members and organizes the ULG into AS layer sub-groups. New Layer 2 structures and procedures are disclosed to enhance bearer management for Sidelink groupcast communications.
