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: Methods, systems, and devices for wireless communications are described. A multicast architecture may support flexible change between unicast and multicast operations and may support additional traffic types (e.g., Internet Protocol and Ethernet traffic). For example, the multicast architecture may include transmitting data over a shared multicast radio bearer (MRB) and/or specific data radio bearers (DRBs), a multicast user plane function (UPF) for supplying the multicast data to a base station, multicast data from different radio access networks (RANs), protecting the multicast data through creating a group key, ciphering the multicast data sent on the MRB using the group key, and transitioning the multicast data from a source RAN to a target RAN.

Abstract: Enabling Ethernet Header Compression (EHC) for use with data sent within a Non-Access Stratum (NAS) control plane of a wireless communication network. In one aspect, a wireless communication device sends a signal to a wireless communication network indicating the device supports EHC for data transfer over a control plane. The device obtains a response from the wireless communication network indicating the wireless communication network supports EHC for data transfer over the control plane. The device then sends an Ethernet packet compressed using EHC to the wireless communication network over the control plane. The wireless communication device may be configured to send a request to the wireless communication network to use EHC before sending the Ethernet packet compressed using EHC. The device then sends the compressed Ethernet packet only if the request is granted. In another aspects, complementary EHC features are provided within a network component of the wireless communication network.

Abstract: Methods, systems, and devices for wireless communications are described that provide for truncated identification indicators. A user equipment (UE) may receive control signaling indicating a truncating configuration for an identification indicator. The truncating configuration may indicate a set of bits within an initial identification indicator to remove to generate a truncated identification indicator. The UE may remove the indicated set of bits and transmit the truncated identification indicator to a base station. The base station may receive the truncated identification indicator and reconstruct the initial identification indicator according to the truncating configuration. The base station may reconstruct the initial identification indicator by adding the set of bits (e.g., removed by the UE to generate the truncated identification indicator) to the truncated identification indicator.

Abstract: Certain aspects provide a method for wireless communication. The method generally includes deriving a network specific identifier (NSI) in a network access identifier (NAI) format, the NSI including a network identifier (NID) stored at the UE, generating a subscription concealed identifier (SUCI) based on the NSI for authentication of the UE with a non-public network (NPN), and sending the SUCI to a network entity for the authentication of the UE with the NPN.

Abstract: Aspects described herein relate to enabling data network devices to communicate using wireless network nodes, including user equipment (UE) and/or core network nodes, in a wireless network. The data network devices can have associated mechanisms for interfacing with the wireless network nodes, and the wireless network functions can facilitate transparent transfer of control information for the associated mechanisms.

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.
