A relay node may detect conflicts regarding media access control (MAC) addresses. The relay node may receive a request to establish a links with a source node and a target node. The relay node may receive the MAC addresses of the source node and the target node. The relay node may detect a conflict associated with the MAC addresses of the source node and the target node. The relay node may release the link with the target node.

Wireless transmit/receive unit (WTRU) to WTRU relay media access control (MAC) access conflict support

Systems and methods are described herein for handling connection rejects via a wireless transmit/receive unit (WTRU)-to-WTRU (U2U) relay associated with backoff times on behalf of a source end WTRU. A relay WTRU may retry to establish connection with a target WTRU on behalf of a source WTRU, for example, based on receiving a rejection (e.g., with a backoff value) from the target WTRU. The source WTRU may associate the reject message to the target WTRU, and the relay WTRU may be available to reach other target WTRUs. The relay WTRU may send a reject message to other source WTRUs (e.g., if the back off duration is active, running) for the same target WTRU.

Handling connection rejections via U2U relay associated with backoff times on behalf of a source end WTRU

A relay node may detect conflicts regarding media access control (MAC) addresses. A target node may receive a request from the relay node. The request may comprise a request to establish communications with the target node. The target node may send, to the relay node, an indication of the MAC address of the target node. The target may receive a link release message from the relay node. The link release message may comprise an indication of conflict associated with the MAC address of the target node.

A wireless transmit receive unit (WTRU) may be configured to perform an edge application server (EAS) discovery procedure for a user session. The WTRU may be configured to determine, based on the EAS discovery procedure, that there are no available target EAS (T-EAS) instances for the user session. The WTRU may be configured to determine whether the user session supports application context relocation (ACR) to a cloud application server (CAS) using ACR configuration information (ACI). The WTRU may be configured to establish a connection with the CAS based on the ACI. The WTRU may be configured to send a notification to one or more ACR entities indicating that ACR to the CAS has been initiated. The WTRU may be configured to obtain CAS details using the ACI.

Edge-cloud application context migration

A relay node may detect conflicts regarding media access control (MAC) addresses. A source node may send a request to the relay node. The request may be a request to establish communications with a target node. The source may send, to the relay node, an indication of the MAC address of the source node. The source node may receive a reject message from the relay node. The reject message may comprise an indication of a conflict associated with the MAC address of the source node.

A wireless transmit/receive unit (WTRU) may send a discovery request to a first edge enabler server (EES) instance to obtain edge application server (EAS) information. The WTRU may receive a discovery response from the first EES instance. The discovery response may indicate a list of EAS information and/or registrar EES information for one or more EAS instances in the list of EAS information. The WTRU may select an EAS instance based on one or more of the list of EAS information or the registrar EES information for the one or more EAS instances. A second EES instance of the plurality of EES instances may be the registrar EES of the selected EAS instance.

Wireless transmit/receive unit (WTRU) driven edge service discovery and selection

A method for UE-to-UE (U2U) relay discovery security is disclosed. The method may comprise provisioning an end-UE with security material for a direct discovery set and a U2U discovery message and provisioning a U2U relay with security material for the U2U discovery message. The security material for the direct discovery set may comprise at least one of: A ProSe restricted code, associated key material, or an indicator associated with a relay service code (RSC) that indicates whether the RSC supports per ProSe direct discovery set protection. The method may comprise sending, by the end-UE to the U2U relay, a direct connection request (DCR) message. The DCR message may comprise at least one of: an RSC, and end-UE User info identification (ID), or a ProSe restricted code. The method may comprise sending, by the end-UE, an indication for direct discovery set protection.

Methods and apparatus for WTRU-to-WTRU relay discovery security and privacy

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.
