The present disclosure discloses a method for transmitting a signal, a network device, and a terminal device. The method includes: a network device determines transmission information of a synchronization signal block, where the transmission information includes information on the number m of the synchronization signal block, and information on a time-domain resource set over which the m synchronization signal block is transmitted, where the time-domain resource set includes m time-domain resource unit over which the m synchronization signal block is transmitted, and locations of m time-domain resource units in different time-domain resource sets are not completely the same; the network device sending the transmission information to a terminal device, so that the terminal device receives, according to the transmission information, the m synchronization signal block transmitted by the network device.
