Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications entity, such as a user equipment (UE), a base station, a network core, or an application server, may identify a round-trip time (RTT) latency requirement that may pertain to a round-trip latency in wireless communications between the UE and the base station. The wireless communications entity may identify a one one-way directional delay budget that satisfies the RTT latency requirement for an application of an application server. The application server may be in communication with the UE via the base station. The wireless communications entity may modify a value of the one-way directional delay budget and transmit a message that is associated with the modified value of the one one-way directional delay budget.

Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a user equipment (UE) may establish a connection with a base station. The connection may correspond to one or more quality of service (QoS) flows for communications between the UE and the base station. The base station may transmit a configuration for a QoS flow to the UE in response to establishing the connection. The configuration for the QoS flow may include a set of one or more parameters specific to a direction of the QoS flow. The UE and the base station may communicate data in the direction of the QoS flow in accordance with the set of one or more parameters.

Abstract: Methods, systems, and devices for wireless communication are described. For example, the described techniques provide for a first device (e.g., a cellular modem or user equipment (UE)) mapping quality of service flows of a first radio access technology (e.g., cellular) to service classes of a second RAT (e.g., Wi-Fi). The first device may communicate mapping information that indicates the mapping to a second network device (e.g., a router). The first device and the second device may communicate various packets via the quality of service flows and the service classes.

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: 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.

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.

The UE may provide, for display and based at least in part on receiving the indication, network selection information associated with a set of networks. The network selection information may include an indication that a given network accommodates inbound roamers.

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: Methods, systems, and devices for wireless communications are described. To communicate using non-restricted radio capabilities, a user equipment (UE) may transmit a UE capability message to a network (e.g., via a base station) that indicates a set of radio capabilities that the UE may use to communicate. The network may identify subscription information for the UE and may determine one or more restricted radio capabilities of the set of radio capabilities based on the subscription information for the UE. The network may transmit a message to the UE that includes a radio capability modification indication indicating the one or more restricted radio capabilities and a UE radio capability identifier corresponding to the subset of radio capabilities of the set of radio capabilities that are not restricted. The UE may receive the message, identify the restricted radio capabilities, and communicate with the network using the subset of non-restricted radio capabilities.

A communication device, otherwise known as a user equipment (UE) may configure an indication associated with network slice information. The UE may determine, based on the indication, that the network slice information is subject to network slice-specific authentication and authorization (NSSAA). Additionally or alternatively, the UE may determine an authentication credential associated with network slice information, and transmit, to an access and mobility management function (AMF), an indication related to an availability of an authentication credential associated with the network slice information. The UE may access a network slice associated with the network slice information based on the NSSAA of the network slice information.
