The present invention provides a method and device for detection and synchronization of broadcast channel propagation time interval. The device for detection and synchronization of broadcast channel propagation time interval includes: a phase sequence generation unit, which is configured to receive continuous N sub-frames, and obtains the phase sequence with the length of N, by figuring out the phase sequence of the downlink synchronous code relative to time slot 0 in each sub-frame, wherein N is the integer of the modulation phase number larger than the standard phase modulation sequence; and detection and synchronization unit, configured to determine whether to synchronize with the broadcast channel based on the phase sequence with the length of N, and determine whether to receive the broadcast channel information at the next transmission time interval.
