Abstract
A cell search method in an asynchronous mobile communication system. For cell search, a UE searches signals received from Node Bs in a slot synchronization step, calculates the timing offset of each of the Node Bs by comparing signals having slot peaks higher than a first threshold with each other among the searched signals in a frame synchronization and code group identification step, and detects the timing offsets of neighbor Node Bs by comparing the timing offsets of signals higher than a second threshold with each other in a code identification step. In addition, Node Bs that transmit signals higher than the second threshold in the code identification step are included in a candidate set and are subject to a cell search periodically.
