Abstract: The present invention discloses a data sending method and a communications device. The method includes: sensing, by a communications device, a carrier located in a first unlicensed frequency band, where the first unlicensed frequency band includes at least one carrier; and sending, by the communications device, data on a carrier whose channel state is sensed to be idle. The communications device senses a first carrier in the first unlicensed frequency band, and sends the data on the first carrier that is successfully sensed to be idle. Another communications device may also sense in the first unlicensed frequency band, and send data in the first unlicensed frequency band when sensing successfully. Therefore, users of different services may fairly contend and coexist in an unlicensed frequency band.

Abstract: This application provides a display method adaptive to a driving status of a vehicle and a related apparatus, are applied to a vehicle with a self-driving function. When the vehicle is switched to a manual driving state, a cockpit display screen in the vehicle presents a first display state, and a screen height of the cockpit display screen in the first display state is a first height. When the vehicle is switched to a self-driving state, the cockpit display screen in the vehicle presents a second display state, and a screen height of the cockpit display screen in the second display state is a second height. The second height is greater than the first height. When the vehicle is in different driving states, the cockpit display screen may present different heights, so that an entertainment requirement and a safe driving requirement that are of a user both can be met.

Abstract: A synchronization processing method, including sending, in a first time unit, by a network device, a first synchronization signal having one or more first beams to a terminal device, and sending, in a second time unit, a second synchronization signal having one or more second beams to the terminal device. The first synchronization signal and the second synchronization signal cause the terminal device to determine, according to the first synchronization signal and the second synchronization signal, an optimal transmit beam of the network device for the terminal device from the one or more first beam and the one or more second beams, and further to determine a time sequence in which the optimal transmit beam is located. A time offset corresponding to each first beam and second beams is different, and is a difference between a time sequence of the beams and a time sequence of the second beams.

Abstract: The present invention provides a synchronization method of user equipment and user equipment, where the method includes: when the user equipment accesses a millimeter-wave band network, performing first synchronization in a cellular band by using a cellular band network that covers the millimeter-wave band network; and performing second synchronization in a millimeter-wave band by using the millimeter-wave band network. In the present invention, after the first synchronization in the cellular band is performed, the second synchronization in the millimeter-wave band is performed by using the millimeter-wave band network, which avoids a case in which the user equipment acquires a PSS in a PSS synchronization window that slides in the millimeter-wave band for a long time, thereby reducing overheads, narrowing a range of the synchronization window, and accelerating detection of a PSS in the millimeter-wave band, so that the user equipment quickly and accurately performs synchronization in the millimeter-wave band.
