Apparatus and method for transmitting inter-working signal in wireless communication system

摘要

A Base Station (BS) includes an apparatus and method for transmitting cell information. The BS is in the a communication system of a small cell size in a wireless communication environment in which a communication system of a large cell size and the communication system of the small cell size are hierarchically constructed in the same area. The method includes confirming reference signal transmission information for transmitting a reference signal including its own cell information, if a reference signal transmission interval arrives according to the reference signal transmission information, transmitting the reference signal through an operation frequency of a macro BS of the large cell size including the BS itself, and, if it is not the reference signal transmission interval, providing service through its own operation frequency or operating in a power saving mode.
