Publication number: 20240073979Abstract: Smart vehicle-to-everything (V2X) preemptive connections for emergency and/or potential accident scenarios. A V2X-enabled vehicle may determine a current route of the vehicle and high-risk areas through which the vehicle may travel (e.g., a hospital zone, high pedestrian traffic area, etc.). The vehicle may determine a distance (d) from a beginning of the high-risk area and begin establishing a V2X connection upon reaching the determined distance. The V2X-enabled vehicle may also, or alternatively, pre-emptively establish a V2X connection upon detecting an event initiative of an emergency, a hazardous situation, or a potential emergency. Examples of such events may include a sharp turn, a vehicle speed exceeding a speed threshold, a sudden acceleration or declaration, etc. A preemptive V2X connection may, for example, enable vehicles to begin communicating with one another faster in case of a threat, emergency, or unsafe conditions for vehicles in the area.Type: ApplicationFiled: August 10, 2023Publication date: February 29, 2024Inventors: Tarakkumar G Dhanani, Vijay Gadde, Vijay Venkataraman, Sharad Garg, Rohit Thareja, Sanjeevi Balasubramanian

Publication number: 20240022630Abstract: A mobile communication device is configured to receive updated network data, such as updated Content Delivery Network (CDN) data utilized to access a first network, without accessing the first network and a second network, such as a Wi-Fi or cellular network. The mobile communication device periodically transmits, via a peer-to-peer (P2P) network, a beacon signal indicating a network data request for the updated network data. A rate at which the mobile communication device periodically transmits the beacon signal is based on various criteria, such as an origination date of network data stored on the mobile communication device, an amount of time between the origination date and the present date, a battery health of the mobile communication device, and/or various inputs to the mobile communication device. An additional mobile communication device receives the beacon signal and transmits the updated network data to the mobile communication device.Type: ApplicationFiled: September 27, 2023Publication date: January 18, 2024Inventors: Dhruv Khati, Krishna Myneni, Shiva Krishna Narra, Sanjeevi Balasubramanian, Anjaneyulu Maganti

Publication number: 20230412203Abstract: Embodiments herein provide various apparatuses and techniques to for enhanced handling of receiver desensitization, “desense,” in electronic devices that is caused by an operation of the device. In an embodiment, sensitivity of a receiver affected by desense may be determined based on receiver sensitivity without desense and a desense offset value. Desense mitigation measures may be applied based on the strength of the signal received by the receiver being less than the receiver sensitivity affected by desense. The desense mitigation measures may include deactivating the device operation that causes desense, enabling the device operation that causes desense only during certain times, and enabling antenna diversity. In some embodiments, various power and signal-to-noise ratio thresholds may be used for conditional application of different desense mitigation measures.Type: ApplicationFiled: June 15, 2022Publication date: December 21, 2023Inventors: Sharad Sambhwani, Apurva Pande, Dirk Nickisch, Pallavi Suresh Mastiholimath, Prashanthan Pathamadai Krishnan, Sairamm Prabakar, Sanjeevi Balasubramanian, Sriram Krishnan

Publication number: 20230397095Abstract: A device executing a low-latency application that uses a Wi-Fi link may switch from the Wi-Fi link to using a second link to a multi-subscriber (MSIM) PHS device. The device may access, via the second link, any one of multiple cellular links, each cellular link corresponding to a different respective cellular subscription of multiple subscriptions used by the PHS device. The application executing on the device may thus use a preferred cellular link from among the multiple cellular links. The preferred cellular link may be determined based on parameters corresponding to the plurality of cellular links for each respective cellular subscription. The parameters may be obtained from a location database. The preferred cellular link (which may presently correspond to a primary subscription) on the PHS device may be switched to be a different cellular link (which may correspond to a non-primary subscription) during execution of the application on the device.Type: ApplicationFiled: June 1, 2022Publication date: December 7, 2023Inventors: Bharath Jayaram, Ajoy K.

Publication number: 20230397271Abstract: This application describes methods and apparatus to manage data transport across multiple radio links for 5G-capable wireless devices. Under certain criteria, including performance of at least one radio link, a mobility state of a 5G-capable wireless device, and data transport requirements for a latency sensitive application session, the 5G-capable wireless device sends buffer status report (BSR) requests for one or more both of the radio links to prioritize and transition uplink (UL) data between radio links before a measurement reporting threshold is met. In some embodiments, the 5G-capable wireless device proactively sends BSR requests for radio resources before the UL data is generated by the latency sensitive application session. In some embodiments, the 5G-capable wireless device duplicates UL data for the latency sensitive application session across multiple radio links.Type: ApplicationFiled: June 3, 2022Publication date: December 7, 2023Inventors: Vijendrakumar K.

Publication number: 20230370107Abstract: An electronic device may include radios that transmit signals using antennas. Control circuitry may assign radio-frequency exposure (RFE) budgets to the radios. The control circuitry may classify and predict attributes of application data for transmission over the radios, may generate a per-radio data prediction based on the classified attributes, and may generate the RFE budgets based on the classified attributes. Each radio may transmit application data based on its data prediction and according to its RFE budget. A dynamic portion of the RFE budget may be reserved for control signaling. RFE planning in this way may ensure that the device optimally utilizes its RFE budget, increasing overall RFE during some time periods so sufficient transmit power is available, and ensuring that RFE is distributed across the radios depending on the amount and criticality of the data to be transmitted by each radio.Type: ApplicationFiled: May 16, 2022Publication date: November 16, 2023Inventors: Sharad Sambhwani, Madhukar K.
