Abstract: Apparatus, methods, and computer-readable media for facilitating time synchronization functionality at user equipment are disclosed herein. An example method for wireless communication at a first device includes transmitting, to a second device, capability information indicating that the first device is capable of operating as a PTP grand master clock. The example method also includes receiving, from the second device, one or more PTP parameters based on the capability information indicating that the first device is capable of operating as a PTP grand master clock. Additionally, the example method includes generating, based on the one or more PTP parameters received from the second device, a first PTP message including time information. Further, the example method includes transmitting the first PTP message including the time information to one or more downstream devices in communication with the first device.

Abstract: A method of wireless communication by a UE (user equipment) includes transmitting a list to an IMS (IP multimedia subsystem) service center. The list includes multiple mobile station international subscriber directory numbers (MSISDNs). The method also includes receiving a paging message indicating different causes for the paging message. A method of wireless communications by a network determines whether a call initiator is in a list received from a UE (user equipment) in response to receiving a mobile terminated call for the UE. The list comprises multiple mobile station international subscriber directory numbers (MSISDNs). The network also transmits a message to the UE indicating whether the mobile terminated call is from one of the MSISDNs in the list.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may identify a marking of one or more packets, of a quality of service (QoS) flow, with a transport layer identifier associated with a QoS of the QoS flow, wherein the transport layer identifier persists between a user plane function (UPF) and a user equipment (UE). The network node may provide the one or more packets via one or more tunnels with the QoS of the QoS flow. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether a standalone non-public network (SNPN), to which the UE is not subscribed, permits access to subscribers of a network to which the UE is subscribed. The UE may register with the SNPN based at least in part on a determination that the SNPN permits access to subscribers of the network to which the UE is subscribed. Numerous other aspects are provided.

Abstract: Techniques are discussed herein for supporting periodic or triggered location of a user equipment (UE) using control plane (CP) optimization with optional use of Early Data Transmission (EDT). A location server (LS), such as a 5G LMF, sends a request to a UE for periodic or triggered location and includes a request and/or criteria for using CP optimization. After confirming the request, the UE monitors for periodic or triggering events and, for each detected event, sends an event report to the LS which may include location information. In embodiments, the UE establishes a signaling association with a RAN node to send the event report using CP optimization and optionally using EDT. The RAN node may then release the signaling association after the LS returns a single response to the UE.

Abstract: Techniques are discussed herein for supporting periodic or triggered location of a user equipment (UE) using Early Data Transmission (EDT). A location server (LS), such as a 5G LMF, sends a request to a UE for periodic or triggered location and includes a request and/or criteria for using EDT. After confirming the request, the UE monitors for periodic or triggering events and, for each detected event, sends an event report to the LS which may include location information. In embodiments, the UE establishes a signaling connection with a RAN node but not with a core network to send the event report using EDT. The RAN node may then release the signaling connection, either immediately or after the LS returns a single response to the UE.

Abstract: Aspects of the present disclosure relate to a mechanism to enable interworking between fifth generation system (5GS) network slicing and evolved packet core (EPC) connectivity. In an example, techniques are provided for existing packet data unit (PDU) sessions that provide connectivity to a network slice from a set of network slices. Connectivity to the network slice is in response to a user equipment (UE), that uses network slices, moving between a 5G network and a 4G network. The existing PDU sessions are connected to a dedicated EPC core network that supports the same services provided by the network slice.

Abstract: A method of wireless communication by a user equipment (UE) without a radio resource control (RRC) connection to a base station includes receiving system information from the base station and transmitting a data communication to the base station over a control plane without establishing an RRC connection with the base station. A UE in an RRC suspended state may transmit a data communication to the base station over a user plane without resuming an RRC connection with the base station. The data communication may comprise data and UE identity information and/or a cause indication. A base station may indicate resources in the system information for the transmission of the data communication information and receive the data communication over the control plane without establishing an RRC connection with the UE or over a user plane without resuming an RRC connection with an RRC suspended UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a radio access network (RAN) configuration for a plurality of service modules that correspond to a plurality of services and a plurality of service-specific UE contexts. The UE may transmit, while in an inactive state, a resume identifier (ID) and one or more service indices corresponding to one or more requested services of the plurality of services. The UE may receive a response indicating one or more valid services of the one or more requested services. The UE may transmit a communication associated with a valid service of the one or more valid services. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a radio access network node, an indication that a time synchronization change has been detected. Accordingly, the UE may adjust a clock associated with the UE based at least in part on the indication. Numerous other aspects are described.
