METHOD AND APPARATUS FOR CELL SEARCH IN COMMUNICATION SYSTEM

摘要

A cell searching method in a communication system and a device are provided to transmit a cell number safely through the second synchronous channel after obtaining frame synchronization by the first synchronous channel by using an error correction code or repeatedly sending cell information, thereby variably controlling a time taken through the second synchronous channel according to channel situations. Slot timing and frame timing are detected by using the first synchronous channel. An ID of a cell to which a terminal belongs or a group ID of the cell is detected by using the second synchronous channel. The slot timing is detected from a synchronous code which constitutes the first synchronous channel. One code sequence is estimated among N code sequences according to the number of synchronous slots of the first predetermined synchronous channel, and the frame timing is detected from the estimated code.
