Abstract: Methods, devices, and systems for changing a layer 2 (L2) identifier (ID) during an ongoing vehicle-to-everything (V2X) session between a source wireless transmit/receive unit (WTRU) and a peer WTRU include communicating between the source and a peer WTRUs based on an existing layer 2 (L2) identifier (ID). On a condition that a trigger event occurs, the source WTRU generates a new source L2 ID, communicates the new source L2 ID to the peer WTRU, receives from the peer WTRU a message that responds to the new source L2 ID, and communicates between the source WTRU and the peer WTRU based on the new source L2 ID.

Abstract: Systems and methods are described herein for enabling discovery and selection of a WTRU-to-network relay by a remote WTRU and handling a WTRU-to-network relay configuration update. The WTRU-to-network relay may broadcast a service type indicating that the service type is available or conditionally available based on the WTRU-to-network relay slicing configuration. The WTRU-to-network relay may update broadcasting the service type or the indication that the service type as being conditionally available based on update of the WTRU-to-network relay slicing configuration. The WTRU-to-network relay may relay traffic between one or more distinct remote WTRUs and the core network node via a WTRU-to-network relay. The WTRU-to-network relay may reuse an existing PDU session for relay traffic or send a PDU session establishment request to network with the requested PDU session parameters depending on if the session parameters associated with an existing PDU session match the PDU session requirements of the remote WTRU.

Abstract: The disclosure pertains to methods and apparatus for minimization of service interruption in wireless networks, such as 5G networks. According to an embodiment, a method, implemented in a wireless transmit/receive unit, WTRU, comprises: transmitting, to a second network, first information indicating a request to register with the second network, wherein the first information comprises information indicating an identity of a first network to which the WTRU is currently registered; receiving, from the second network, second information indicating an acceptance of registration to the second network, wherein the second information comprises information indicating a maximum amount of PDU sessions, wherein the maximum amount corresponds to a limit of allowable PDU sessions; and transmitting, to the second network, third information indicating a request to establish a second amount of PDU sessions no more than the limit of allowable PDU sessions.

Abstract: An unmanned aerial vehicle (UAV) authentication and authorization may be performed by a third-party service provider (e.g., an unmanned aerial system traffic management (UTM) over a user plane (UP)). An UAV may be configured to send an UAV ID to a network. The UAV may receive, from the network, security information that indicates an authorization of a connection to a third-party service provider. The UAV may establish, based on the security information, the connection to the third-party service provider for communications with the third-party service provider. The security information may include signature information of the third-party service provider, and one or more of a subscription identifier (ID) associated with the UAV, the UAV ID, or an ID of the third-party service provider.

Abstract: Systems, methods and instrumentalities are described herein that provide security and/or privacy support for wireless transmit receive units (WTRUs) communicating via a WTRU to WTRU relay. A source WTRU may obtain a new IP address from a relay WTRU via a link identifier update request. The source WTRU may indicate to the relay WTRU which one or more target WTRUs are to be informed of the new IP address. The source WTRU may indicate to the relay WTRU whether the target WTRU's ID(s) should be changed. The relay WTRU may send the source WTRU's new IP address to authorized target WTRUs. The source, relay, and target WTRU may use tokens to grant or receive authorizations for sharing each other's IP addresses.

Abstract: Methods, apparatus, systems, architectures and interfaces for performing secure command and control (C2) communications in an Unmanned Aerial System (UAS) including a UAV controller (UAV-C) are provided. The method includes on condition that the UAV has completed a registration procedure with a network, transmitting, to a session management function (SMF) of the network, a packet data unit (PDU) session establishment request message; performing a secondary authentication, with any of the USS and the UTM, via the SMF; receiving a PDU session establishment accept message including C2 security information; and establishing C2 communications security with the peer UAV-C using the C2 security information.

Abstract: 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.

Abstract: 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.

Abstract: A method for use in wireless transmit/receive unit (WTRU) which assesses both a first network and a second network to receive radio frames from each of the first network and the second network is disclosed. The method comprise: obtaining a first paging occasion (PO) as the first network's current PO and a second PO as the second network's current PO; determining whether there is a PO collision between the first PO and the second PO, on condition that there is the PO collision, selecting a network from the first network and the second network, and sending a request to the selected network; receiving, from the selected network, a collision avoidance parameter corresponding to the request; calculating a third PO for the selected network using the collision avoidance parameter, and using the third PO as the selected network's current PO.

Abstract: Method and apparatus for secure access control in wireless communications are disclosed. In an example, a method includes receiving a broadcast message including system information, identifying a first set of hashed identifiers (IDs) and a first random number based on the system information, and each ID of the first set of hashed IDs is individually hashed using at least the first random number. The method also includes calculating a first hash value for each ID of a second set of IDs using at least the first random number, determining whether at least a hashed ID of the second set of IDs matches a hashed ID of the first set of hashed IDs, and sending a request message based on a determination that at least a hashed ID of the second set of IDs matches a hashed ID of the first set of hashed IDs.
