Abstract:
1. A method for transmitting a Synchronization CHannel (SCH) in a cellular wireless communication system, the method comprising: checking a number of available Primary SCH Scrambling Codes (PSCs) among PSCs defined for Primary SCH (P-SCH) in the system; selecting a default PSC and transmitting a P-SCH signal using the default PSC in each of underlying cells when the number of available PSCs is 1, the default PSC being preset with priority for use in User Equipments (UEs) of the system for searching the P-SCH; and selecting PSCs for the cells from among the available PSCs so adjacent cells have different PSCs and transmitting P-SCH signals with the selected PSCs in the cells when the number of available PSCs is 2 or larger.
