Patent number: 11476989Abstract: User Equipments (UEs) may be assigned a set of aggregated component carriers for downlink carrier aggregation and/or carrier selection. Some UEs may be incapable of transmitting uplink signals over all component carriers in their assigned set of aggregated component carriers. In such scenarios, a UE may need to perform SRS switching in order to transmit SRS symbols over all of the component carriers. Embodiments of this disclosure provide various techniques for facilitating SRS switching. For example, a radio resource control (RRC) message may be used to signal a periodic SRS configuration parameter. As another example, a downlink control indication (DCI) message may be used to signal an aperiodic SRS configuration parameter. Many other examples are also provided.Type: GrantFiled: June 19, 2020Date of Patent: October 18, 2022Assignee: Futurewei Technologies, Inc.Inventors: Jialing Liu, Weimin Xiao, Murali Narasimha, Brian Classon, Qian Cheng

Patent number: 11470611Abstract: Communications in a wireless network for carrier Selection and switching are provided. A terminal in the wireless network is simultaneously receiving data on at most m carriers. A base station in the wireless network sends an activation command associated with more than m carriers to the terminal. The terminal activates the more than m carriers. Then the base station selects a first subset from the activated carriers, and sends a first monitoring command associated with the first subset via a first physical-layer signaling to the terminal. When load and/or interference situations are changed, the base station selects a second subset from the activated carriers, and sends a second monitoring command associated with the second subset via a second physical-layer signaling to the terminal, wherein the first subset is different from the second subset.Type: GrantFiled: October 12, 2020Date of Patent: October 11, 2022Assignee: Futurewei Technologies, Inc.Inventors: Jialing Liu, Weimin Xiao, Qian Cheng

Patent number: 11469618Abstract: Described herein is a wireless charging system including switched capacitor (SC) rectifiers with output regulation. The load for the receiver on mobile devices using wireless charging is a battery. Regulation is needed for battery charging applications, e.g. constant voltage charging, constant current charging, and pulsed charging. For this purpose, the wireless power transfer (WPT) receiver can possess some “intelligence” to monitor the output voltage/current, adjust the behavior of the electronic circuitries and achieve a closed-loop control. Because a multilevel switched-capacitor (MSC) rectifier has output control ability, this can allow the MSC rectifier to directly charge the battery without an additional DC/DC charger on-board the device.Type: GrantFiled: October 19, 2020Date of Patent: October 11, 2022Assignees: Futurewei Technologies, Inc., University of Tennessee Research FoundationInventors: Chongwen Zhao, Daniel Costinett, Songnan Yang
