Patent ID: 8923859

Claim:
A method for a cell search, comprising: obtaining primary synchronization signal (PSS) relevant information in each time unit by calculation according to a time-domain signal received by a terminal in each time unit; calculating first secondary synchronization signal (SSS) relevant information in an i th time unit according to PSS relevant information in a previous time unit of a cycle segment and a time-domain signal received by the terminal in the i th time unit of the cycle segment; accumulating the first SSS relevant information in the i th time unit and SSS relevant information cached in a first space to obtain first accumulated SSS relevant information; updating the SSS relevant information cached in the first space to the first accumulated SSS relevant information, wherein i is an integer; calculating a cell search result according to the first accumulated SSS relevant information when i is an odd number; calculating second SSS relevant information in the i th time unit according to PSS relevant information in a first time unit in the cycle segment and the time-domain signal received by the terminal in the i th time unit; accumulating the second SSS relevant information in the i th time unit and SSS relevant information cached in a second space to obtain second accumulated SSS relevant information; updating the SSS relevant information cached in the second space to the second accumulated SSS relevant information; and calculating a cell search result according to the second accumulated SSS relevant information when i is an even number.
