  • Publication number: 20240356687
    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.

  • Patent number: 12126462
    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.

  • Publication number: 20240349083
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive, from a time-sensitive networking (TSN) application function (AF), a first request for a parameter at a device-side TSN translator (DS-TT) associated with the wireless communication device. The wireless communication device may generate a cause code that indicates that the parameter is supported but not available, if the parameter is not available. The wireless communication device may transmit the cause code to the TSN-AF. Numerous other aspects are described.

  • Publication number: 20240334207
    Abstract: Methods, systems, and devices for wireless communications are described. A plurality of public land mobile networks (PLMNs) across the plurality of different mobile network operators (MNOs) may participate in a shared operator service offering for facilitating provision of intelligent services in ambient computing environments. A first network entity, such as a reader device, may receive from an energy harvesting (EH)-capable device in an ambient computing environment a back-scattered signal that includes identification information associated with the EH-capable device. In some cases, the first network entity and the EH-capable device may be associated with different PLMNs or different MNOs. Based on configuration information indicating a type of enrichment information to collect, the first network device may obtain enrichment information associated with the EH-capable device and may cause the identification information and the enrichment information to be transmitted to a second network entity.

  • Patent number: 12096220
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a registration request for restricted access (RA), wherein the registration request selectively includes an onboarding access request. The UE may selectively communicate with an onboarding network to authenticate and authorize a particular network based at least in part on whether the registration request includes the onboarding access request. The UE may complete the RA registration after transmitting the registration request and based at least in part on selectively communicating with the onboarding network to authenticate and authorize the particular network. Numerous other aspects are described.

  • Patent number: 12047266
    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.

  • Publication number: 20240155420
    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.

  • Publication number: 20240121655
    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.

  • Publication number: 20240064830
    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.
