  • Publication number: 20230224993
    Abstract: This application relates to the field of communication technologies, and discloses a communication method and apparatus. The method includes: A terminal device receives indication information from a first access network device. The indication information is used to indicate to fall back a capability of the terminal device to a first protocol version. The terminal device communicates, based on the indication information, with the first access network device by using first capability information. A protocol version corresponding to the first capability information is lower than or equal to the first protocol version. In this method, because a network device can explicitly indicate to fall back the capability of the terminal device to the first protocol version, the terminal device can specially reduce the capability, so as to quickly resolve a communication problem caused by incompatibility between the terminal device and the access network device.

  • Patent number: 11699931
    Abstract: A rotor structure of a magnet motor includes a rotating shaft and an iron core on the rotating shaft. Magnet grooves are disposed inside the iron core along a circumferential direction with a magnet provided therein. A distance between an edge line of the magnet groove close to a circumferential edge of the iron core and the circumferential edge of the iron core varies so that a width of a flux barrier formed varies. One end of a long side of the magnet groove close to the circumferential edge is formed with an anti-demagnetization groove communicating with the magnet groove, and an edge line of the anti-demagnetization groove tilts toward the circumferential edge of the iron core. Process slots are provided between the magnet grooves and the circumferential edge of the iron core that are used to increase a salient rate and reluctance torque of the motor.

  • Publication number: 20230139024
    Abstract: This application relates to the field of communication technologies, and discloses a communication method and apparatus. The method includes: A terminal device receives an identifier of a filtering protocol version from an access network device, and then sends first capability information of the terminal device to the access network device based on the filtering protocol version. In this method, the terminal device may report capability information based on the filtering protocol version sent by the access network device. Compared with a manner in which the terminal device directly reports the capability information, this method can effectively reduce a communication problem caused by mismatch between a protocol version supported by the terminal device and a protocol version supported by the access network device and/or a protocol version supported by a core network device.
