Abstract
Provided are a cell search method a forward link frame transmission method an apparatus using the methods and a forward link frame structure. The cell search apparatus includes a sync acquirer acquiring synchronization of sync channel symbols using a sync channel of a forward link and a group detector detecting at least one hopping codeword element belonging to a hopping codeword of a target cell from a forward link signal containing sync channel symbols sequence-hopped using a hopping codeword corresponding to a code group to which a scrambling code of each cell belongs based on the acquired synchronization and detecting a code group of the target cell based on the detected hopping codeword element wherein the hopping codewords are orthogonal to a cyclic shift operation. Accordingly a cell search time and the complexity of the cell search can be reduced.
