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 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.

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: 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: A system, method, and/or device for relay communications are provided. In some implementations, a method implemented by a WTRU may include sending a Link Modification Request (LMR) message to a second WTRU via a first relay, wherein the LMR message includes one or more new most significant bytes (MSBs) for a new Key NR ProSe identifier (KNRP ID), receiving a link modification accept (LMA) message from the second WTRU via a first relay, where the LMA message includes one or more new least significant bytes (LSBs) for the new KNRP ID, forming 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 device may include sending a direct connection request (DCR) message to the second WTRU via a second relay, where the DCR message includes the new KNRP ID.

Abstract: 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.
