Abstract: Disclosed are apparatuses and techniques for wireless communications. In an aspect, path information from a plurality of relays is received at a server. A relay cell list for an area of interest is compiled based on the received path information from the plurality of relays. The relay cell list is provided to a user equipment (UE). The UE can use the relay list to assist in the search and/or selection of relays in the wireless communications network.

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: A core network receives data from at least one of an AF, a DN, or a UE. A UPF having small data capability processes the data for transport with a low overhead and without initiating a bearer set up protocol. The data may be transported between the UE and the UPF as an RRC payload over a NAS protocol. The data may be received from an AF or DN external to the core network and may be processed to transport the data to the UE based as an RRC payload. The data may be received as uplink data from a UE, e.g., in an RRC payload. The UPF may process the RRC payload to obtain the data and may transport the data to the AF or DN. The UPF may perform IP header compression, data encryption, and/or buffering of data for a UE in an idle mode.

Abstract: A core network receives data from at least one of an Application Function (AF), a Data Network (DN), or a User Equipment (UE). A Session Management Function (SMF) processes the data for transport with a low overhead as a session management (SM) payload over a Non Access Stratum (NAS) protocol. The data may be received from an AF or DN external to the core network and may be processed to transport the data to the UE based as a SM payload. The data may be received as uplink data from a UE, e.g., in an SM payload. The SMF may processed the SM payload to obtain the data and may transport the data to the AF or DN. The SMF may perform IP header compression, data encryption based on an SMF encryption key, and/or buffering of data for a UE in an idle mode.

Abstract: Certain aspects of the present disclosure provide techniques for establishing a dual third generation partnership project (3 GPP) access protocol data unit (PDU) session. An example method performed by a user equipment includes selecting a first access link for a protocol data unit (PDU) session, selecting a second access link based on the first access link, and establishing the PDU session based on the selected first access link and the second access link.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for supporting an interface between a system that implements sensitive networking (TSN) and a wireless communications system. In one aspect, a network entity, which may be configured to communicate over the wireless communications system, may interface with one or more TSN bridges of the TSN system. The network entity may share timing information with a centralized network configuration (CNC) entity of the TSN system and may perform a time domain mapping between a first clock used by the CNC entity and a second clock used by the network entity. For example, the network entity may map absolute times using a clock drift between the first clock and the second clock and may convert time durations using a cumulative rate ratio between the first clock and the second clock.

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 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.
