    Abstract: Systems, methods, and instrumentalities are disclosed that are associated with cellular communications for unmanned aerial vehicles and associated devices. A WTRU may initiate multiple PDU sessions. The WTRU may initiate a first protocol data unit (PDU) session. The WTRU may receive one or more session parameters for a second PDU session. The one or more session parameters for the second PDU session may be received via the first PDU session. The WTRU may initiate the second PDU session using the one or more session parameters (e.g., based on an authentication and authorization associated with the first PDU session being successful). The WTRU may send or receive an operation communication via the second PDU session. The operation communication may comprise an unmanned aerial vehicle command and control message or an unmanned aerial vehicle payload message.

    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: A client application running on a WTRU is configured to communicate data traffic over a TCP session with an MPTCP stack running on the WTRU. The data traffic is exchanged with a server application over a first MPTCP sub-flow with a first mobile edge (ME) host device. The WTRU is anchored to a second ME anchor node. The WTRU receives a first message from a second ME host device indicating that the WTRU should join a second MPTCP sub-flow with the second ME host device. The WTRU joins the second MPTCP sub-flow, responsive to the first message, wherein the second sub-flow is configured not to exchange data traffic. The WTRU receives a second message from the second ME host device configuring the second MPTCP sub-flow to exchange data traffic. The WTRU exchanges the data traffic with the server application over the second MPTCP sub-flow with the second ME host device.

    Abstract: A wireless transmit/receive unit (WTRU) may be configured to support UAV authentication and/or authorization. A WTRU may obtain a UAV profile (e.g., UAV id) via registration with a network. UAV authentication and authorization may be performed with a UAS server/UTM based on the UAV profile. UAV authentication and authorization procedures may be UAS-based (e.g., via a UTM over a user plane) and/or EAP-based (e.g., via a UTM with an AMF or SMF authenticator). A WTRU may setup a PDU session, for example, for UAV authentication with a UAS server/UTM over a user plane. A WTRU may perform UAV authentication with a UAS server/UTM via AMF (e.g., EAP over NAS/MM) or via SMF (e.g., EAP over NAS/MM during PDU session establishment). A UAS id and/or UAV-C id may be received, for example, via a UCU procedure or a PDU session establishment accept message.

    Abstract: A method and apparatus where an announcing WTRU may request peer discovery from a Pro Se function, and the ProSe function may provide information associated with a monitoring WTRU to the announcing WTRU as a result of the monitoring WTRU having discovered the announcing WTRU. A discoveree WTRU may request peer discovery from a ProSe function where the ProSe function sends a unique ProSe query code to a discoverer WTRU. As a result of the discoveree WTRU detecting the ProSe query code on radio interface, the discoveree WTRU triggers a match report procedure to obtain information associated with the Discoverer WTRU.

    Abstract: Methods and apparatuses are described herein for dynamic PC5 communication adaptation. For example, a UE may receive, from a vehicle-to-everything control function (V2X CF) or a vehicle-to-everything application server (V2X AS), a V2X provisioning message that includes a first transmission profile and determine, based on the first transmission profile, a first range to configure PC5 communication of a plurality of UEs associated with the V2X platoon. When a number of UEs joining the V2X platoon exceeds a certain threshold, the UE may transmit, to the V2X CF or the V2X AS, a modification request message requesting a second transmission profile. The UE may receive, from the V2X CF or the V2X AS, a modification response message that includes the second transmission profile and determine, based on the second transmission profile, a second range to reconfigure the PC5 communication of the plurality of UEs associated with the V2X platoon.

    Abstract: Methods and apparatuses are described herein for paring an unmanned aerial vehicle (UAV) with a UAV-controller (UAV-C). For example, a UAV having a UAV wireless transmit/receive unit (UAV WTRU) may transmit, to an access and mobility management function (AMF), a non-access stratum (NAS) request message that includes a paring request indication and a UAV-controller (UAV-C) identification (UAV-C ID). The UAV-C ID may be carried in a paring request to an unmanned aerial system (UAS) service supplier (USS)/UAS traffic management (UTM) for paring authorization of the UAV with a UAV-C associated with the UAV-C ID. The UAV may receive, from the AMF, a NAS response message that includes an unmanned aerial system (UAS) identification (UAS ID) indicating that the UAV is paired with the UAV-C, wherein the UAS ID is assigned by the USS/UTM.

    Abstract: A method addressing handover procedure failure or cancellation includes receiving, by a remote wireless transmit/receive unit (WTRU) connected to a source NodeB, a handover command to begin a handover procedure to establish a connection with a target NodeB on a network. A method may further include, on a condition that the handover procedure fails, transmitting, by a relay TRU, a handover failure/cancellation indication to the remote WTRU and cancelling, by the remote WTRU, the handover procedure. A method may also include initiating, by the remote WTRU, a radio resource control (RRC) re-establishment procedure to connect with the source NodeB or a new NodeB.

    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.
