Abstract: The present disclosure provides a multi-excitation-source axial-flux permanent-magnet motor with partitioned, hierarchical, and variable poles, and a variable-condition driving control system. The motor mainly includes a main magnetic pole and an auxiliary magnetic pole. The main magnetic pole is responsible for providing a main air gap flux and is connected in series with a dual-stator magnetic circuit. The auxiliary magnetic pole is responsible for adjusting an air gap field and is connected in parallel with the dual-stator magnetic circuit. Magnetic fluxes of the main magnetic pole and the auxiliary magnetic pole together constitute the air gap field. The present disclosure can control a flux path of the auxiliary magnetic pole by controlling the magnitude of a current applied to a field winding, thereby adjusting an air gap flux, expanding a speed range of the motor, and achieving variable-condition operation of the motor.

A user equipment (UE) may receive from a network entity, a control message triggering the UE to provide a time-domain aperiodic channel state information (A-CSI) report for indicating time-domain channel state information (CSI) associated with CSI reference signal (CSI-RS) resources within an observation window, where a beginning of the observation window is based on when the control message is received. The UE may perform performing measurements of channel state information reference signals (CSI-RSs) received via the CSI-RS resources that occur within the observation window. The UE may then transmit, to the network entity based on the control message, the time-domain A-CSI report indicating measured time-domain CSI associated with the observation window, where the measured time-domain CSI is based on the measurements.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support emergency messaging using a mobile relay. For example, a first user equipment (UE), may transmit a first emergency message indicating a request for relaying a second emergency message to one or more network entities, the first UE being out-of-coverage of a network entity. The first UE may receive, from a second UE associated with an aircraft, a feedback message in response to the first emergency message and may transmit, to the second UE, a second emergency message based on receiving the feedback message. The second UE may receive the second emergency message and transmit, over an air-to-ground wireless communications network, an indication based on the first emergency message and the second emergency message.

For example, a network entity may transmit to a user equipment (UE) configuration information that configures the UE for communications on noncontiguous carriers of a single cell. The network entity and the UE may then communicate on the noncontiguous carriers in accordance with the configuration information.
