GENERATING DOWNLINK FRAME AND SEARCHING FOR CELL

摘要

The present application relates to a method of generating a downlink frame. The method of generating the downlink frame includes: generating a first short sequence and a second short sequence indicating cell group information; generating a first scrambling sequence and a second scrambling sequence determined by the primary synchronization signal; generating a third scrambling sequence determined by the first short sequence and a fourth scrambling sequence determined by the second short sequence; scrambling the short sequences with the respective scrambling sequences; and mapping the secondary synchronization signal that includes the first short sequence scrambled with the first scrambling sequence, the second short sequence scrambled with the second scrambling sequence and the third scrambling sequence, the second short sequence scrambled with the first scrambling sequence and the first short sequence scrambled by the second scrambling sequence and the fourth scrambling sequence to a frequency domain.

1. A method of generating a down link frame in a base station, comprising:
generating a downlink frame including a primary synchronization signal and a secondary synchronization signal; and including cell identity group information in the secondary synchronization signal and including cell identity information within a cell identity group in the primary synchronization signal so that a terminal searches for a cell using the cell identity group information in the secondary synchronization signal and the cell identity information in the primary synchronization signal, wherein the secondary synchronization signal comprises a first short sequence and a second short sequence, the first short sequence is scrambled with a first scrambling sequence, and the second short sequence is scrambled with a second scrambling sequence and a third scrambling sequence, wherein the first scrambling sequence and the second scrambling sequence are determined based on the cell identity information contained in the primary synchronization signal, and the third scrambling sequence is determined based on the first short sequence.
