Publication number: 20220295410Abstract: Methods, systems, and devices are described for enhanced power savings in wireless devices through mobile initiated dormancy procedure. A user equipment (UE) may establish radio resource control (RRC) connectivity with a base station of the network, and transmit and receive one or more distinct signaling messages for dormancy state initialization and suspension at the UE. Dormancy state implementation at the UE may conserve available power resources at the UE during periods of inactive data transaction. The one or more signaling messages may contain a single or multi-bit indication for the receiving device, and may be transmitted via direct signaling on upper layer protocols of the data network or mapped to allocated resources of a data transmission. The signaling messages may sustain synchronization between the interpreted functional mode of the UE at the base station and the implemented mode at the UE.Type: ApplicationFiled: May 27, 2022Publication date: September 15, 2022Inventors: Shravan Kumar Raghunathan, Srinivasan Balasubramanian, Parthasarathy Krishnamoorthy, Yonas Kidane, Chetan Chakravarthy, Kumarabhijeet Singh, Arvindhan Kumar, Krishna Rao Mandadapu

Patent number: 11388720Abstract: Capability exchange enhancements include filtering and/or indexing. In some aspects, a user equipment (UE) determines UE capabilities to be reported to a network based on one or more of: one or more enquiries from the network, received system information, a home operator policy, configuration associated with public land mobile network (PLMN) information of one or more networks, a user preference, or a service type. In other aspects, a UE may report a subset of UE capabilities for features used for the connection establishment. Following connection establishment, the UE may use an identifier to communicate a more complete set of modes of operation that the UE is currently capable of performing. Base stations of the network may share the reported subset so that the UE may avoid transmitting the subset to a target base station.Type: GrantFiled: February 12, 2020Date of Patent: July 12, 2022Assignee: QUALCOMM IncorporatedInventors: Shravan Kumar Raghunathan, Muthukumaran Dhanapal, Srinivasan Balasubramanian, Gavin Bernard Horn, Aziz Gholmieh, Parthasarathy Krishnamoorthy, Aiping Zhang

Patent number: 11006327Abstract: Methods, systems, and devices for wireless communications are described that provide for call continuity following radio link failure (RLF) through re-establishment of a voice call using a same or different radio access technology (RAT) before the call is dropped. Upon detection of RLF on a connection supporting a voice call, a UE may initiate a drop call timer and scan for available connections. The voice call may be attempted to be re-established if a connection is available on using a RAT of an existing connection. The voice call in such cases may continue without the call being dropped. Upon expiration of the drop call timer, the UE may attempt to establish a connection using a RAT identified during the duration of the drop call timer.Type: GrantFiled: September 27, 2018Date of Patent: May 11, 2021Assignee: QUALCOMM IncorporatedInventors: Shravan Kumar Raghunathan, Srinivasan Balasubramanian, Parthasarathy Krishnamoorthy, Chetan Chakravarthy, Yonas Kidane, Arvindhan Kumar, Kumarabhijeet Singh, Krishna Rao Mandadapu

Patent number: 10827300Abstract: Techniques are provided to initiate signal transmissions for possible opportunistic reception by a mobile device, and/or to initiate opportunistic reception of signal transmissions for use in mobile device position location estimation. For example, a mobile device may use assistance data to identify a first signal to be transmitted over a first frequency band and a second signal to be transmitted over a second frequency band during a specific period of time. At least a portion of the second frequency band may be outside of the first frequency band. The mobile device subsequently attempts to opportunistically receive at least the first signal and the second signal via a receiver tuned to a reception frequency band that encompasses at least the first frequency band and the second frequency band. The mobile device may then process the opportunistically received signals to obtain measurements corresponding to at least the first and second signals.Type: GrantFiled: November 7, 2019Date of Patent: November 3, 2020Assignee: QUALCOMM IncorporatedInventors: Akash Kumar, Amit Jain, Ankita, Muthukumaran Dhanapal, Shravan Kumar Raghunathan, Parthasarathy Krishnamoorthy, Hargovind Prasad Bansal
