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.

Abstract: The present invention relates to a base station, a small cell, and a method for scheduling a communications link resources. A first small cell reports load information and channel state information of a channel between the first small cell and a neighboring second small cell to a base station. The first small cell receives link pre-scheduling signaling from the base station. The link pre-scheduling signaling includes wireless resource occupation information that indicates an occupancy of a wireless resource of the first small cell by a backhaul link. The first small cell allocates a first wireless resource in available wireless resources to the backhaul link according to the channel state information and the wireless resource occupation information, and allocates a second wireless resource in the remaining available wireless resources to an access link used for data transmission between the first small cell and a user equipment device.
