    • 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.
    • 一种在支持可扩展带宽的基于正交频分复用(OFDM)的蜂窝无线通信系统中发送/接收承载下行链路系统信息的广播信道的方法和装置。 该方法包括将包括基本系统信息的第一主要广播信道(P1-BCH)符号映射到以系统频带的中心频率为中心并且具有广播信道(BCH)传输带宽的中间频带,以及映射第二主广播信道(P2 -BCH)符号,包括不包括基本系统信息的核心系统信息到具有BCH传输带宽的第一和第二传输频带,并且位于与两侧的中心频率相邻的两个频带内并且具有由用户设备支持的最小接收带宽(UE ),当系统频带的带宽是最小接收带宽的至少两倍时。 以这种方式,该方法和系统便于UE在小区之间移动。
