Patent number: 10966207Abstract: Radio circuitry controls wireless transmit power to User Equipment (UEs). The radio circuitry receives wireless signals generated using different Quadrature Amplitude Modulation (QAM) constellation sizes. The circuitry converts the wireless signals into data symbols and converts the data symbols into uplink data. The radio circuitry determines when average symbol error is excessive for a set of QAM constellation sizes. The radio circuitry determines when the UEs are concentrated in an inner coverage range. When both the average symbol error is excessive and the UEs are concentrated in the inner range, the radio circuitry reduces transmit power and transmits wireless signals to the UEs at the reduced transmit power. When the average symbol error is no longer excessive or when the UEs are no longer concentrated in the inner range, the radio circuitry increases transmit power and transmits wireless signals to the UEs at the increased power level.Type: GrantFiled: March 1, 2019Date of Patent: March 30, 2021Assignee: Sprint Communications Company L.P.Inventors: Sathyanarayanan Raghunathan, Muthukumaraswamy Sekar, Maheswaran Vijayakumar, Suresh Majjara

Patent number: 10750413Abstract: Disclosed are methods and systems for configuring service of a user equipment device (UE). When the UE has dual-connectivity service, such as EN-DC service, poor quality on one of the UE's air-interface connections could result in transition of the UE to single-connectivity service. To address technological issues that may arise in this process, one of the UE's serving Node-Bs (NBs) could control teardown of an access bearer homed to the other of the UE's serving NBs. Further or alternatively, a control-plane signaling path that is homed to one of the UE's serving NBs could be replaced with a control-plane signaling path instead homed to the other of the UE's serving NBs. In addition, in appropriate circumstances, when such reconfiguration occurs, service of the UE could be switched from one core network to another.Type: GrantFiled: September 13, 2018Date of Patent: August 18, 2020Assignee: Sprint Spectrum L.P.Inventors: Sathyanarayanan Raghunathan, Muthukumaraswamy Sekar, Maheswaran Vijayakumar, Suresh Majjara
