Patent ID: 8059728

Claim:
A method for transmitting a Broadcast CHannel (BCH) carrying system information in a cellular communication system, which supports a scalable bandwidth and uses multiple access technology, the method comprising: mapping BCH modulation symbols including system information to a central band of a system band, the central band having a bandwidth equal to a transmission bandwidth of the BCH, wherein the BCH modulation symbols are constituted by sub-carrier symbols and are divided into first and second resource blocks, wherein each of the sub-carrier symbols refers to a modulation symbol mapped to one sub-carrier, and wherein the first resource block is mapped into a first half of the system band and the second resource block is mapped into a second half of the system band; additionally mapping the first resource block of the BCH modulation symbols into the second half of the system band, and the second resource block of the BCH modulation symbols into the first half of the system band, when the system bandwidth is two times or larger than the maximum reception bandwidth of a User Equipment (UE); and transmitting a frequency domain signal, to which the first and second resource blocks are mapped, to the UEs located within the cell.
