Abstract: A method for transmitting a synchronization sequence, and a method and a device for synchronization detection are provided, the method for transmitting the synchronization sequence including: setting a target synchronization sequence with good autocorrelation characteristic, where at least one segment of sequence truncated in a time domain or a frequency domain of the target synchronization sequence is a sub-synchronization sequence, and the sub-synchronization sequence has good autocorrelation characteristic and the sub-synchronization sequences have good cross-correlation between each other; and transmitting the target synchronization sequence to a user equipment.
