    Abstract: Systems and methods for supporting multiple uncrewed aerial vehicle (UAV) Service Suppliers (multi-USS) are described. The methods may be performed by a wireless transmit/receive unit (WTRU) including a UAV application enabling (UAE) client located in the UAV with the method performed with the UAV in-flight. Steps may include: sending a registration request to a UAE server, the registration request including an indication of multi-USS capability; receiving a registration response message that includes an indication that the UAE server supports multi-USS capability; receiving a multi-USS configuration request that includes multi-USS configuration parameters related to conditions under which the UAE client may initiate a USS change and a list of allowed USSs; sending a multi-USS configuration response; and performing a multi-USS change and sending a multi-USS change notification based on the multi-USS configuration parameters.

    Abstract: A relay wireless transmit/receive unit (WTRU) may receive a direct communication request (DCR) from a remote WTRU requesting connectivity service (e.g., connectivity session parameters such as single-network slice selection assistance (S-NSSA!), data network name (DNN)). The relay may determine that the connectivity session for the service is subject to a secondary authentication and authorization (A&A), based on an indication associated with the connectivity session if already established and/or an indication associated DN from relay proximity service (ProSe) configuration. Based on the determination, the relay may trigger a network-controlled authorization for the remote WTRU. The relay WTRU may send a direct communication accept (DCA) message including a pending secondary A&A. and configure a traffic filter associated with the connection (e.g., a PC5 link) to discard data traffic from the remote WTRU until a successful completion of the secondary A&A.

    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.

    Abstract: A wireless transmit-receive unit (WTRU) may be provided. The WTRU may be configured to receive a first message from a first relay WTRU. The first message may indicate a service provided by a second WTRU and a first measurement associated with a broadcast message. The WTRU may be configured to determine a second measurement. The second measurement may be associated with the first message received from the first relay WTRU. The WTRU may be configured to send a second message to the first relay WTRU if the first measurement satisfies a first criteria for selecting a relay from a plurality of relays and the second measurement satisfies a second criteria for selecting the relay from the plurality of relays. The second message may comprise an indication to establish communication between the first WTRU and the second WTRU via the first relay WTRU.

    Abstract: A relay WTRU may receive, from a remote WTRU, a request for connection that includes a PRUK ID. The relay WTRU may transmit, to a PKMF associated with the relay WTRU, a key request message that includes the PRUK ID. The relay WTRU may receive, from the PKMF associated with the relay WTRU, a key response message that includes a GPI. The relay WTRU may transmit, to the remote WTRU, a direct security mode command message that includes the GPI. The relay WTRU may receive, from the remote WTRU, a direct security mode complete message. The relay WTRU may transmit, to the PKMF associated with the relay WTRU, a PRUK confirmation message. The relay WTRU, may receive, from the PKMF associated with the relay WTRU, an acknowledgement that the PRUK confirmation message was received, and transmit, to the second WTRU, an acceptance of the request for connection.

    Abstract: Method, apparatus and systems are disclosed that may be implemented in wireless transmit/receive unit (WTRU), an unmanned aerial vehicle (UAV) and/or a UAV-controller (UAV-C). In one representative method, the UAV may switch from a first Command and Control (C2) communication link between a UAV and a first UAV-C to a second C2 communication link for C2 communications. The method may include determining, by the WTRU, to switch C2 communications from the first C2 communication link to the second C2 communication link based on a C2 switching condition; sending, by the WTRU to a C2 control entity, a notification indicating link information used to determine switching from the first C2 communication link to the second C2 communication link; receiving, by the WTRU from the C2 control entity, information indicating a switch; and switching, by the WTRU, C2 communications from the first C2 communication link to the second C2 communication link.

    Abstract: In an implementation, a second device, for example a second WTRU, may receive a Link Modification Request (LMR) message from a first device, for example a first WTRU, via a first relay. The LMR message may include one or more new MSBs for a new Key NR ProSe identifier (KNRP ID). The second WTRU may send a link modification accept (LMA) message to the first WTRU via the first relay. The LMA message may include one or more new LSBs for the new KNRP ID. The second WTRU may form the new KNRP ID by combining the one or more new MSBs with the one or more new LSBs and replacing an existing KNRP ID with the new KNRP ID. The second WTRU may also receive a direct connection request (DCR) message from the first WTRU via a second relay. The DCR message may include the new KNRP ID.
