Abstract: Disclosed in the present invention are a method and device for transmitting and detecting a synchronous signal, which is used to solve the problem that there is currently no clear solution as to how should a terminal detect a synchronous signal when multiple types of base-band numerology are defined in a new wireless communication system. The method comprises: a terminal determining a base-band numerology used to detect a synchronous signal; the terminal detecting the synchronous signal according to the determined base-band numerology. The terminal first determines a base-band numerology used to detect a synchronous signal before detecting said synchronous signal, and then detects the synchronous signal according to the determined base-band numerology, so as to identify the base-band numerology used in the synchronous signal transmission in future communication systems which support multiple types of base-band numerology, thereby correctly detecting the synchronous signal.
