ABSTRACT:
Provided is a method and an apparatus for transmitting/receiving a Broadcast Channel (BCH), by which a User Equipment (UE) can successfully receive system information of neighboring cells in a system supporting the scalability of a UE reception bandwidth and a system bandwidth. The method includes identifying a system bandwidth of a cell by comparing the system bandwidth with reception bandwidths of UEs within the cell, mapping two BCH information blocks including system information to a central band having a bandwidth equal to a transmission bandwidth of the BCH, additionally mapping at least one of the information blocks into each of one-half bands of the system bands, when the system bandwidth is two times an amount of the reception bandwidth, and transmitting a frequency domain signal, to which the information blocks are mapped, to the UEs located within the cell.
