Abstract: Various embodiments include methods for autonomous beam switching by a wireless device. A processor of the wireless device may measure signal parameters of signals received from a first synchronization signal block (SSB) beam of a base station monitored by the wireless device and other SSB beams of the base station, determine whether a difference in measured signal parameters of signals received from the first SSB beam and another SSB beam of the base station satisfies a signal quality difference threshold, and autonomously switching to the second SSB beam as the serving beam in response to determining that the difference in the measured signal parameters of signals received from the first SSB beam and a second SSB beam satisfies the signal quality difference threshold. The signal quality difference threshold may be listed in a table in memory or determined via machine learning.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for a user equipment (UE) to select a data connection based on which applications are active in a foreground process of an application processor. The UE may activate a dedicated data subscription (DDS) based on a list of active applications. In some aspects, the UE may programmatically initiate a DDS switch based on which applications are active. The UE may determine which data connection to activate as the DDS based on the application configuration information and which applications are active. Application configuration information may indicate preferences regarding different data connections to use for each application. The application configuration information may indicate a preferred radio access technology (RAT), a preferred communication network, a preferred subscription, or any combination thereof.

Abstract: A user equipment (UE) modem stores a route selection policy (URSP), the URSP associating each of a plurality of data network name (DNN) identifiers and a corresponding slice, wherein a first DNN identifier (ID) is associated with a first DNN and a first slice and a second DNN ID is associated with the first DNN and a second slice different than the first slice. The modem establishes a first protocol data unit (PDU) session with the first DNN and the first slice in response to receiving a first indication to start a first network interface associated with the first DNN ID. The modem establishes a second PDU session with the first DNN and the second slice in response to receiving a second indication to start a second network interface associated with the second DNN ID.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus of a user equipment (UE) may determine a set of inputs to a neural network configured to predict radio frequency channel conditions or a user context associated with the UE. In some aspects, the set of inputs includes historical data related to a wireless environment, a communication pattern, or a behavior pattern associated with the UE. The apparatus of the UE may determine, using the neural network and based at least in part on the set of inputs, an optimal number of aggregated carriers to maximize one or more of a power parameter or a performance parameter. The apparatus of the UE may communicate using the optimal number of aggregated carriers. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for tracking network traffic for local area network (LAN) subnets in a wireless wide area network (WWAN). In some implementations, a UE of the WWAN may assign a unique public IP address to each router of the LAN. The UE may transmit network traffic received from the LAN to the WWAN. The network traffic originating from any router of the LAN may be associated with the unique public IP address that was assigned to that router. The WWAN may use the unique public IP addresses to generate network traffic information that may indicate amounts of network traffic flowing from each router of the LAN. The WWAN, for example, may use the network traffic information to determine billing information for any router in the LAN.

Abstract: This disclosure provides systems, methods, apparatuses and computer-readable medium for wireless communication. In some aspects, a user equipment (UE) may receive, from a first base station (BS) associated with a fifth generation New Radio (5G NR) radio access technology (RAT), a command of mobility from the 5G NR RAT to a second RAT. The UE may determine that the command of mobility is for voice fallback. The UE may transmit, to a second BS associated with the second RAT and based at least in part on determining that the command of mobility is for voice fallback, a radio resource control (RRC) connection request communication for attempting to communicatively connect with the second BS for voice fallback.

Abstract: Certain aspects of the present disclosure provide techniques for a domain name system (DNS) override for edge computing. Embodiments include receiving signaling indicating an address of a DNS server. Embodiments include receiving signaling indicating an address of an edge DNS server. Embodiments include intercepting a DNS request from an application. Embodiments include changing a destination address of the DNS request to the address of the edge DNS server. Embodiments include intercepting a DNS response from the edge DNS server that is sent in response to the DNS request. Embodiments include upon determining that the DNS response does not comprise a failure notification, changing a source address of the DNS response to the address of the DNS server.

Abstract: Methods, systems, and devices for wireless communications are described that provide for user equipment (UE) camping in a virtual cell. A UE may camp in a virtual cell and may be in an idle mode or an inactive mode in the virtual cell. The UE may transition out of the idle or inactive mode and switch from camping in the virtual cell to connecting to a physical cell encompassed by the virtual cell through reselection, redirection, and handover procedures. The virtual cell may include a central unit and multiple distributed units, which may be configured in various physical implementations. Additionally, the virtual cell may be limited to broadcast only or selective unicast signaling.
