Method for allocating code to cells and planning cells in ofdm cellular system

Abstract

A piece of user equipment (UE), which has received more than two synchronization codes at the same time, has a problem in that the UE may not confirm the synchronization codes due to an increase in inter-signal interference. As a result, the UE may not acquire a primary scrambling code (PSC). A method of transmitting a forward synchronization signal in a wireless communication system includes: each base station existing in a wireless communication system generating a frame according to a predetermined unit of frame timing by using a same external clock signal; and allocating different offsets to frames of adjacent base stations by using the external clock signal so that forward link common channels included in the frames do not overlap each other, and transmitting the frames. In addition, a method of allocating a cell code suitable for an OFDM cellular system, a forward link frame transmitting method, a method of setting timing between cells, and a method of setting timing between a base station and a mobile station can be derived.
