Patent ID: 8200233

Claim:
For use in a base station, an operation method for communicating in a frame divided into a first part comprising a system common signal structure and a second part comprising a communication environment-dependent signal structure in a wireless communication system in which cells co-exist under different communication environments, the operation method comprising: generating physical configuration information about a signal associated with the second part; transmitting the physical configuration information about the signal associated with the second part in the first part; conducting communications by processing signals transmitted and received in the second part according to the physical configuration information; and acquiring a synchronization with a neighbor base station using a synchronization signal received in a self-organization area of the first part from the neighbor base station, wherein the synchronization signal has one of a cyclic prefix and a guard interval that are longer than a cyclic prefix of a signal transmitted in an area other than the self-organization area in the first part, wherein the different communication environments are caused by different types of base stations, and wherein the second part is used by the different types of base stations.
