Abstract: Disclosed in the present invention are a signal transmission method, a network device, and a terminal device. The method comprises: determining a time-frequency resource position of a downlink signal, the downlink signal comprising at least one of a synchronization signal, a broadcast signal, a common control channel signal, a common reference signal and a measurement reference signal, the time-frequency resource position of the downlink signal being on multiple frequency channel numbers of a carrier in a preset time, and the multiple frequency channel numbers being part of frequency channel numbers in a bandwidth of the carrier; and sending the downlink signal according to the time-frequency resource position of the downlink signal. The signal transmission method, the network device and the terminal device in embodiments of the present invention can improve the communication efficiency of the terminal device.

Abstract: Provided are a wireless connection method and device, a terminal and a computer-readable storage medium. The method includes that: when the first mobile terminal is in a screen-off state, a first trajectory input by a user is received. When a second trajectory for a second mobile terminal is matched with the first trajectory, a wireless connection is established between the first mobile terminal and the target mobile terminal.
