Abstract: Systems, methods, and processors are provided for flexibly configuring network slices in device to device communication. In one example, a baseband processor for a relay user equipment (UE) is configured to cause the UE to receive a UE route selection policy (URSP) from a network. The URSP includes respective URSP rules for routing UE traffic through respective network slices to the network. A first URSP rule indicates whether an associated first network slice is designated for remote UE traffic, relay UE traffic, or both remote UE traffic and relay UE traffic. The baseband processor is configured to cause the UE to establish a device to device (D2D) connection with a remote UE to relay remote UE traffic from the remote UE to a base station and assign the remote UE traffic to at least one network slice based on the URSP.

Abstract: MBS key distribution includes processing group information associated with an MB session context received from an AF. At least a portion of the group information comprises a TMGI. A plurality of session join requests received from a plurality of UEs are processed. Each of the plurality of session join requests include the TMGE and are associated with the MB session context. A request associated with the MB session context for transmission to an MB-SMF is encoded. A response associated with the MB session context received from the MB-SMF is processed. The response includes a key derived for each of a portion of the plurality of UEs using a UE ID and the TMGI. A DL NAS message and an N2 message are encoded for the plurality of UEs and a base station, respectively. The DL NAS message and the N2 message include the derived key.

Abstract: Apparatuses, systems, and methods for emergency communications (e.g., voice calls and/or SMS messages) for UE's without cellular coverage (e.g., in non-cellular coverage). A function of a core network may receive, from a relay UE, a request to establish an SOS APN for a host UE, where the request may include at least an approximate location of the host UE, and where the host UE may be out of range of cellular service. The function of the core network may route, based, at least in part, on the approximate location of the host UE, traffic to a PSAP with a coverage area that includes the approximate location of the host UE using the established SOS APN. The approximate location of the host UE may be based, at least in part, on a location of the relay UE.
