The relay WTRU may relay the eMBMS data packet to the remote WTRU based on the ProSe per packet priority level. The relay WTRU may forward the eMBMS data packet to the remote WTRU via a PC5 interface.

Based on the determination, the WTRU may transmit different information to the network. The network slice selection and/or reselection may be initiated by a WTRU or by a network.

Abstract: Aspects relate to delay management techniques to handle delays introduced by high latency links in non-terrestrial networks for non-access stratum (NAS) mobility management and session management procedures. The NAS timers within the user equipment (UE) and core network utilized for mobility management and session management procedures may be configured with different durations, such as a normal duration, an extended duration, or a reduced duration, based on whether the UE is connected to a terrestrial or non-terrestrial radio access network (RAN), one or more capabilities of the UE, and/or the various RAN types (e.g., terrestrial or non-terrestrial) within a registration area that the UE is located in.

Abstract: Procedures, systems, and devices for addressing quality of service (QoS) during an inter-system change of a wireless transmit/receive unit (WTRU) are discussed herein. A WTRU may send a packet data unit (PDU) modification request to a network node, such as a session management function (SMF) device, indicating support for reflective quality of services (RQoS). In response to the modification request, the WTRU may then receive an acknowledgement, after which the WTRU may then be able to send data for a PDU of a specific RQoS. The RQoS may be specific to a single PDU or a plurality of PDUs. The modification request may include Session Management (SM) and/or Mobility Management (MM) information. The modification request may be included in an attach procedure or a tracking area update (TAU).
