ABSTRACT:
A method and apparatus for transmitting/receiving broadcast channels carrying downlink system information in an Orthogonal Frequency Division Multiplexing (OFDM)-based cellular wireless communication system supporting a scalable bandwidth. The method includes mapping first primary broadcast channel (P1-BCH) symbols including basic system information to a middle band centered at a center frequency of a system band and having a broadcast channel (BCH) transmission bandwidth, and mapping second primary broadcast channel (P2-BCH) symbols including core system information excluding the basic system information to first and second transmission bands that have the BCH transmission bandwidth and locate within both bands adjoining the center frequency on both sides thereof and having a minimum reception bandwidth supportable by User Equipments (UEs) within a cell respectively, when a bandwidth of the system band is at least two times of a minimum reception bandwidth. In this way, the method and system facilitates a UE to move between cells.
