Patent ID: 7860050

Claim:
A method of transmitting a broadcast channel (BCH) in a cellular communication system supporting a scalable system bandwidth and employing multiple access technology, the method comprising the steps of: generating first primary broadcast channel (P1-BCH) symbols including basic system information, and second primary broadcast channel (P2-BCH) symbols including core system information excluding the basic system information; mapping the P1-BCH symbols to a middle band centered at a center frequency of a system band and having a BCH transmission bandwidth; mapping the P2-BCH symbols 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 the minimum reception bandwidth; and transmitting the P1-BCH and P2-BCH symbols to the UEs within the cell through subcarriers of the bands to which the symbols are mapped.
