Abstract: A wireless transmit/receive unit (WTRU) may receive a power reporting policy from a network node. The power reporting policy may include one or more triggers associated with sending a power status report. The WTRU may determine that a trigger of the one or more triggers associated with sending the power status report has been satisfied. The WTRU may send the power status report to the network node in accordance with the power reporting policy. The power status report may include power status information associated with the WTRU and/or an indication that indicates the determined trigger to send the power status report.

Abstract: Systems and methods are described herein for a wireless transmit/receive unit (WTRU) activating and/or deactivating user equipment (UE)/WTRU-provided data network (UPDN). The WTRU may advertise availability of UPDN a (e.g., 5G) network. A UPDN software application may be transferred onto and/or installed on a WTRU to implement a UPDN. A WTRU may be authenticated and/or authorized to a host for a given UPDN instance, UPDN installation and/or update may be configured if an authentication fails because a UPDN software application is not up-to-date and/or not installed. A WTRU may provide information to a service provider for installing UPDN and/or update UPDN software. Control connectivity and/or path selection for UPDN may be configured by one or more WTRU route selection policy (URSP) rules. A UPDN profile and/or UPDN subscription profile may be configured in a system (e.g., 5G system (5GS)). UPDN may be provisioned in a (e.g., 5G) network.

Abstract: Procedures, methods, architectures, apparatuses, systems, devices, and computer program products that may be implemented in wireless communications. In one representative method, the WTRU may send one or more age of information (AoI) preferences for a traffic flow to a network entity, and the WTRU may receive one or more AoI rules for the traffic flow from the network entity. The WTRU may receive a packet associated with the traffic flow, and the received packet may include an indication of AoI of the packet. The WTRU may send one or more additional AoI preferences to the network entity, such as upon determining that any of the AoI preferences and/or AoI rules are not satisfied based on the indication of AoI. The indication of AoI may correspond to a processing state of the packet along a path in a network and/or to a time since the packet was created.

Abstract: Methods, apparatuses, systems, etc., directed to support provisioning domains (PvDs) in 5G networks are disclosed herein. In an embodiment, a network entity running a policy control function (PCF), may send to a wireless receive and transmit unit (WTRU) at least one WTRU route selection policy (URSP) rule associated with, for example, PvD descriptors. For example, URSP rules may be configured e.g., as part of the subscription profile and PvD descriptors may be configured e.g., as part of a network-wide configuration. An application function (AF) may use a network exposure function (NEF) application programming interface (API) to access and, for example, update, e.g. through any of NEF and PCF, any of URSP rules and PvD descriptors. According to embodiments, a WTRU may participate in a data network access identifier (DNAI) selection by including a PvD ID in, for example, PDU session establishment messages.

Abstract: Systems, methods, and instrumentalities are disclosed herein for establishing a connection between a network node and a wireless transmit/receive unit (WTRU). A network node (e.g., a user plane function (UPF)) may receive a connection request message from another network node (e.g., a session management function). The connection request may indicate a request to establish a connection between the network node (e.g., the UPF) and a WTRU. The connection request message may indicate a header compression configuration (HCC) supported by a proxy. The network node may receive a request message from the WTRU indicating an HCC supported by the WTRU. The network node may determine a supported HCC using the HCC supported by the proxy and the HCC supported by the WTRU. The network node may configure the proxy to use the supported HCC. The network node may establish a connection with the WTRU.

Abstract: A wireless transmit / receive unit, WTRU, connects to a first AP, receives domain identifiers, requests corresponding descriptors and receives a list of descriptors. An application on the WTRU requests a list of domains and attributes corresponding to service names or service sets, which is returned by the WTRU. The application selects one or more domains for communications, the WTRU selects corresponding network resources and the application connects to local services. After moving to a new location, the WTRU connects to a second AP and receives a second set of domain identifiers, selects the one matching the request from the application and provides these to the application that, with the aid of the WTRU connects to local services.

Abstract: Methods and apparatuses for enabling multi-host multipath secure transport with Quick User Datagram Protocol (UDP) Connections (QUIC) are described herein.

Abstract: An application server receives a request for service from a wireless transmit/receive unit (WTRU) associated with a home network that includes a home subscriber server (HSS) and a bootstrapping server function (BSF) coupled via a Zh reference point. The application server authenticates the WTRU at least in part by (i) redirecting the WTRU to an identity provider co-located with a network application function (IDP/NAF) and coupled to the BSF via a Zn reference point and (ii) receiving an assertion from the WTRU that the IDP/NAF has authenticated the WTRU based on user security settings retrieved from the BSF by the IDP/NAF over the Zn reference point. After authenticating the WTRU, the application server (i) retrieves user-specific Sh-reference-point-type data from the HSS via the IDP/NAF over the Zn and Zh reference points and (ii) provides the service to the WTRU based on the retrieved user-specific Sh-reference-point-type data.
