摘要：
A method and apparatus for transmitting and receiving an SCH in a cellular wireless communication system, in which a number of available PSCs among PSCs defined for P-SCH in the system is checked, a default PSC to be used with priority in UEs of the system for cell search is selected and a P-SCH signal is transmitted with the default PSC in each of underlying cells when the number of available PSCs is 1, and PSCs are selected for the cells from among the available PSCs so adjacent cells have different PSCs and P-SCH signals are transmitted using the selected PSCs in the cells when the number of available PSCs is 2 or larger.
