Abstract: Methods and apparatuses for power saving are described herein. A method performed by a remote wireless transmit/receive unit (WTRU) may include receiving a broadcast message indicating a power saving capability, sending, to a relay WTRU, a request for direct communication, receiving an acknowledgement from the relay WTRU in response to the request for direct communication, and establishing a link to the relay WTRU based on the received acknowledgement. The method may further include sending, to the relay WTRU, a message for registration with a network, receiving, via the relay WTRU, a message from the network in response to the message for registration, sending, to the relay WTRU, a message indicating that a power saving feature is enabled, and adjusting parameters for power saving. The request for direct communication may include information indicating one or more power saving capabilities or power saving requirements of the remote WTRU.

Abstract: Systems, methods, and instrumentalities are described herein that are associated with providing access to a network (e.g., if access to a different network is lost, affected, etc.). A WTRU may act as a relay to another WTRU, For example, a first VVTRU may act as a relay WTRU (e.g., a VVTRU to network relay, such as a proximity services (ProSe) WTRU to network relay) towards a second WTRU (e.g., a remote WTRU). The first WTRU may provide discovery and/or connection establishment associated with the second WTRU accessing the network (e.g., if there is a service disruption to another network).

Abstract: A WTRU (e.g., relay WTRU) may be configured to send a first message. The first message may indicate that the relay WTRU supports a multicast-broadcast service (MBS). The relay WTRU may receive a second message from a WTRU (e.g., a remote WTRU). The second message may indicate an MBS service announcement (SA) request, a remote WTRU identity (ID), and a description of an MBS service. The relay WTRU may determine one or more service parameters. The one or more service parameters may be requested by the MBS SA request. The one or more service parameters may be associated with the MBS service. The WTRU may send a third message to the remote WTRU. The third message may indicate the one or more service parameters.

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: A sensing operation management function (SOMF) with a processor may be configured to receive a wireless transmit/receive unit (WTRU)-initiated sensing request from a network node. The WTRU-initiated sensing request may include one or more of a requested sensing area, a requested service area, a WTRU location, information associated with a serving SOMF, or a periodic service request. The SOMF may be configured to select one or more WTRUs to perform a sensing operation based on the WTRU-initiated sensing request. The SOMF may be configured to send one or more sensing requests to the one or more selected WTRUs. The one or more sensing requests may include one or more of a periodicity for performing the sensing operation, a periodicity for sending sensing responses, or a requested sensing mechanism. The SOMF may be configured to receive one or more sensing responses from the one or more WTRUs. The one or more sensing responses may include sensing data. The SOMF may be configured to send the sensing responses to a WTRU that initiated the WTRU-initiated sensing request via the network node.

Abstract: A wireless transmit/receive unit (WTRU) may function as a relay between other WTRUs. The relay WTRU may receive a domain name system (DNS) query request from a first WTRU for the internet protocol (IP) address of a second WTRU. The DNS query request may comprise the first WTRU's authentication container. The relay WTRU may: send a first authentication request comprising the first WTRU's authentication container to the second WTRU, receive a first authentication response from the second WTRU indicating successful authentication of the first WTRU and comprising the second WTRU's authentication container. send a second authentication request to the first WTRU comprising the second WTRU's authentication container, receive a second authentication response from the first WTRU indicating successful authentication of the second WTRU. and based on successful authentication of the first and second WTRUs. send a DNS response comprising the IP address of the second WTRU to the first WTRU.

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.
