SYNCHRONIZATION PREAMBLE TRANSMISSION METHOD, SYNCHRONIZATION METHOD, DEVICE AND SYSTEM

摘要

A synchronization preamble transmission method, synchronization method, device and system are disclosed in the present invention. The method includes that: the synchronization preamble is transmitted in a superframe, the synchronization preamble comprises one Primary-Preamble (P-Preamble) and two Secondary-Preambles (S-Preambles), wherein, the P-Preamble carries system bandwidth information and the S-Preamble carries cell/sector IDentification (ID) information. The present invention reaches the effect to reduce the overhead of Synchronization CHannel (SCH) on the basis of ensuring the performance of Synchronization access.
