  • Publication number: 20230144151
    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.

  • Publication number: 20230146571
    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.

  • Patent number: 11638312
    Abstract: Certain aspects of the present disclosure provide techniques for communicating, by a user equipment (UE), over multiple slices. A method that may be performed by the UE includes transmitting, from an operating system (OS) to a modem, an indication of a start network request originating from an application, the transmitting of the indication based on a determination that a traffic descriptor associated with the application is a non-default descriptor. The method may also include determining one or more parameters for establishing a new network connection for the application, the one or more parameters determined based on a routing policy that provides mapping between the traffic descriptor and the one or more parameters.

  • Patent number: 11622323
    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.

  • Publication number: 20220417737
    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.

  • Publication number: 20220338258
    Abstract: This disclosure provides systems, methods and apparatuses for enabling collision mitigation for a user equipment (UE) operating in a dual active mode. In some aspects, the UE may generate a communication for a first subscription in a first time window associated with a first priority for a time domain division pattern with a second subscription. The UE may transmit, using the first subscription, the communication in a second time window associated with a second priority for the time domain division pattern. For example, the second time window associated with the second priority may be a time window in which traffic for the first subscription is prioritized. In some aspects, the UE may select modified periodic intervals for transmissions of a communication to mitigate collisions associated with the time domain division pattern. For example, a transmission time of the periodic communication may be varied (or randomized) over time.
