Abstract: A magnetic induction communication-based vehicle control apparatus and method are disclosed. The apparatus includes a first coil (1001), a processor (1002), and a communications interface (1003). The first coil (1001) receives a signal of second coils (1004) laid along a lane. There is a preset relative location relationship between the first coil (1001) and the second coils (1004). When a vehicle equipped with the vehicle control apparatus deviates from a predetermined travel direction, the first coil (1001) generates an electromotive force signal based on a change in the relative location relationship between the first coil (1001) and the second coils (1004). The processor (1002) outputs a second signal based on the electromotive force signal, where the second signal is used to indicate the vehicle to adjust a running track to travel along the predetermined travel direction.

Abstract: A terminal device obtains first indication information, where the first indication information indicates an ephemeris parameter of a first satellite at a first moment. The terminal device determines a position and a velocity of the first satellite at a second moment based on the ephemeris parameter of the first satellite at the first moment, where the second moment is after the first moment. In response to determining that an error of the position of the first satellite at the second moment is less than a first threshold and an error of the velocity of the first satellite at the second moment is less than a second threshold, the terminal device obtains second indication information, where the second indication information indicates an ephemeris parameter of the first satellite at a third moment, and the third moment is before the second moment.

Abstract: This application provides a HARQ feedback method and an apparatus. The method includes: A terminal device receives first indication information, where the first indication information indicates a first quantity of retransmissions of first data. The terminal device obtains a second quantity of retransmissions based on a HARQ feedback result and/or a decoding result of second data, where the second data is data retransmitted by the terminal device before the terminal device retransmits the first data. The terminal device sends the first data by using a target quantity of retransmissions, where the target quantity of retransmissions is a smaller one of the first quantity of retransmissions and the second quantity of retransmissions. According to the method, data transmission is performed by using the determined target quantity of retransmissions, so that a delay caused by a HARQ can be reduced, resources can be saved, and power consumption can be reduced.
