  • Patent number: 10700562
    Abstract: An electric motor includes 3 stators and 1 rotor which employs distributed winding. The axial magnetic circuit generates permanent magnet torque, while the radial magnetic circuit generates reluctance torque. By decoupling the axial and radial magnetic circuits, the separation and the independent control of the permanent magnet torque and the reluctance torque are realized. Each stator and rotor can be processed independently, and modular installation can be processed, thereby reducing the difficulty of motor processing.

  • Patent number: 10693610
    Abstract: 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.

  • Patent number: 10660046
    Abstract: Embodiments are provided for implementing network adaptation schemes, including small cell on/off adaptation and transmission power control. In an embodiment method for supporting network adaptation, a network component receives a discovery reference signal (DRS) from a network controller that is in a switch-off transmission mode. The network component then performs measurements according to the DRS, and reports the measurements to a network associated with the network controller. In return, the network component receives a radio resource control (RRC) signaling from the network. The RRC signaling includes configuration information allowing a connection between the network component and the network controller. The network component then connects with the network controller in accordance with the configuration information.
