Abstract: Techniques described herein enable the provision of configuration information between one or more network entities of a home service provider (SP) and one or more network entities of a network such as a standalone non-public network (SNPN) to support a user equipment (UE) associated with the home SP that is visiting the SNPN. For example, the configuration information may enable the UE to access or use services provided by the home SP. In some aspects, the configuration information may include a proxy call session control function address, tunneling information, or the like. In this way, functions are supported for a UE visiting an SNPN despite a home SP that provides the functions not having a session management function (SMF) for signaling of configuration information supporting the functions. Thus, the interconnection of SNPNs and home SP networks is improved.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment, UE, may identify (305) that the UE is not connected with a first network to which the UE subscribes, and identify a fallback configuration (310). The UE may determine (315), based on the fallback configuration, a second network of one or more other networks with which the UE is to connect. The UE may attempt (320) to connect with the second network based on the fallback configuration and the UE not being connected with the first network. In some cases, a base station of a network may establish a connection with UEs based on receiving registration messages from the UEs in response to transmitting an indication that the network is available as a fallback network, identify a congestion level of the network and switch to a non-subscriber rejection mode in which the base station rejects connection with non-subscriber UEs.

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: 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 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 communication are described. A user equipment (UE) may truncate or remove a number of bits from its UE identity based on identity truncating information to generate a truncated UE identity. The truncated UE identity can be transmitted by eMTC devices to a base station in an RRC connection request, and can be used by the base station to determine which core network entity stores the UE's capabilities. In some implementations, the UE may truncate or remove a number of bits from the 48-bit 5G-S-TMSI based on the identity truncating information to generate a 40-bit truncated 5G-S-TMSI that can be transmitted by an eMTC device to the base station in the RRC connection request and yet still provide the base station with enough information to determine which AMF stores the UE context.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may establish a protocol data unit session with a network data analytics function (NWDAF) entity of a wireless network provider; receive, via the protocol data unit session and using user plane signaling, a request for one or more parameters related to an application executing on the user equipment; and provide the one or more parameters to the NWDAF entity via the protocol data unit session using user plane signaling. Numerous other aspects are provided.

Abstract: Various techniques and approaches described herein may be applied to control congestion at a session management (SM) function (SMF) based on at least one back-off timer maintained at a user equipment (UE). In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE may be configured to establish a protocol data unit (PDU) session with a SMF. The UE may be configured to determine whether a back-off timer associated with the PDU session is terminated. The UE may refrain from sending, to the SMF, data over a control plane associated with the PDU session when the back-off timer is unterminated. The UE may send, to the SMF, the data over the control plane associated with the PDU session when the back-off timer is terminated.

Abstract: Disclosed are techniques for wireless communication that over come problems associated with conventional approaches including load balancing and handover efficiency issues. For example, in one aspect a wireless communication technique takes into account the load of a relay before a UE is switchted from one relay to another. In another example, a wireless communication technique ensures that UEs are handed over to relays that will be able to serve the UE as the mobile relay continues to follow its expected path (such as streets or tracks), which may be known or determined.

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: Methods, systems, and devices for wireless communications are described herein. For example, a UE may transmit a radio capability identifier to a network entity. In some examples, the radio capability identifier may indicate a set of radio capabilities of the UE. In response to receiving the radio capability identifier, the network entity may determine feedback indicating whether the set of radio capabilities indicated by the radio capability identifier satisfy a respective radio capabilities of a radio capability profile for an application associated with the UE. The network entity may transmit the determined feedback to the UE and, in response, the UE may establish a session for the application associated with the UE.
