Abstract

The invention relates to a detecting method of a synchronous signal position and the small area search method adopting the detecting method. According to the invention, the position of the prearranged area containing the part of the synchronous signal in the whole subframe is obtained, with small area search only to the part to reduce the relevancy operation quantity to large extent.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method for detecting the position of a synchronization signal and a cell searching method using the method. Background technique [0002] In the TD-SCDMA system, the cell search process of the terminal can be composed of the following four steps. Through these four steps, the downlink synchronization code (SYNC_DL), the basic midamble code (Basic Midamble code), Scrambling code, frame synchronization, BCH information, and chip timing information, etc. [0003] FIG. 1 is a flowchart for explaining the entire initial cell search process. [0004] First, in step 1, the terminal searches for a downlink pilot time slot (hereinafter abbreviated as "DwPTS"). The terminal device searches for the downlink synchronization code (SYNC_DL) used in the cell (Cell) to be searched using the 32 types of downlink synchronization codes (SYNC_DL) known in advance, and obtains timing s...
