Patent number: 10536805Abstract: A range between a first wireless device and a second wireless device is estimated using a first mechanism based on messages transmitted over a first communication channel. The first communication channel is associated with a first radio access technology capability of the wireless devices. One or more metrics indicative of an accuracy of the range estimates provided by the first mechanism are obtained. A second mechanism to estimate a range between the first wireless device and the second wireless device may be implemented in favor of the first mechanism when the metric fails to satisfy a criterion. The second mechanism is based on unicast messages transmitted over a second communication channel. The second communication channel is associated with a second radio access technology capability of the wireless devices and may be the same as, or different from, the first communication channel.Type: GrantFiled: November 26, 2018Date of Patent: January 14, 2020Assignee: QUALCOMM IncorporatedInventors: Venkatesan Nallampatti Ekambaram, Urs Niesen, Jubin Jose, Xinzhou Wu

Patent number: 10502840Abstract: A method of determining a position of a mobile platform includes obtaining a plurality of pseudorange measurements from multiple time epochs of a satellite navigation system (SPS) and obtaining a plurality of visual-inertial odometry (VIO) velocity measurements from a VIO system. Each time epoch of the SPS includes at least one pseudorange measurement corresponding to a first satellite and at least one pseudorange measurement corresponding to a second satellite. The method also includes combining the plurality of pseudorange measurements with the plurality of VIO velocity measurements to identify one or more outlier pseudorange measurements in the plurality of pseudorange measurements. The one or more outlier pseudorange measurements are then discarded from the plurality of pseudorange measurements to generate a remaining plurality of pseudorange measurements.Type: GrantFiled: February 3, 2016Date of Patent: December 10, 2019Assignee: QUALCOMM IncorporatedInventors: Urs Niesen, Venkatesan Nallampatti Ekambaram, Lionel Jacques Garin, Jubin Jose, Xinzhou Wu

Patent number: 10333612Abstract: A method, wireless device and computer program product for expanding the coverage of a cellular network. A wireless device (e.g., cellular telephone) is able to communicate with a base station in a cell of the cellular network over a non-cellular interface via another wireless device in a cell through the use of multi-hopping. A wireless device may request permission to communicate with the base station over a non-cellular interface via hopping off another wireless device when its signal strength is below a threshold. Alternatively, a wireless device may receive a request to communicate with the base station over a non-cellular interface via hopping off the wireless device that sent the request when that wireless device has excess capacity in its bandwidth with the base station. By enabling wireless devices to communicate with a base station in such a manner, the effective capacity of the cellular network is expanded and the effective capacity of the cellular network is improved.Type: GrantFiled: September 25, 2017Date of Patent: June 25, 2019Assignee: Board of Regents, The University of Texas SystemInventors: Vidur Bhargava, Sriram Vishwanath, Jubin Jose

Patent number: 10182088Abstract: Methods, systems, and devices are described for utilization of an unlicensed radio frequency spectrum band for performing a ranging procedure. Performance of the ranging procedure may be triggered by a signal transmitted in a licensed radio frequency spectrum band. While conventional ranging in Long Term Evolution (LTE) communications, for example, using the licensed radio frequency spectrum band may be limited to a 10 MHz bandwidth, using the unlicensed radio frequency spectrum band for ranging may allow use of a wider bandwidth, such as 100 MHz or greater. Use of the wider bandwidth may result in more accurate ranging measurements (e.g., time-of-arrival estimation).Type: GrantFiled: July 8, 2015Date of Patent: January 15, 2019Assignee: QUALCOMM IncorporatedInventors: Jubin Jose, Venkatesan Nallampatti Ekambaram, Xinzhou Wu, Hong Cheng, Shailesh Patil
