SYNCHRONIZATION PREAMBLE TRANSMISSION METHOD, SYNCHRONIZATION METHOD, DEVICE AND SYSTEM

摘要

A synchronization preamble transmission method, a synchronization method, a device and a system are disclosed in the disclosure. The method includes: transmitting synchronization preambles in a superframe, the synchronization preambles comprise one Primary Preamble (P-Preamble) and two Secondary-Preambles (S-Preambles), wherein the P-Preamble carries system bandwidth information and the S-Preambles carry cell/sector Identification (ID) information. The disclosure reaches the effect of reducing the overhead of Synchronization Channel (SCH) on the basis of ensuring the performance of synchronization access.
