摘要： A wireless communication system, and more particularly, a base station apparatus to lend an idle resource to another base station or to borrow an idle resource from another base station is provided. A borrowing base station apparatus includes a transmitter to transmit an idle resource borrowing message to a lending base station, and a receiver to receive, from the lending base station in response to the idle resource borrowing message, an idle resource lending message including information regarding whether to lend an idle resource of the lending base station, such that the transmitter transmits data to a terminal using the idle resource. The borrowing base station may borrow an idle resource from the lending base station to use the borrowed idle resource to perform data transmission.

摘要： An apparatus and method for exchanging frequency bands used by a plurality of base stations are provided. A base station for exchanging frequency bands includes a receiving unit to receive first quiet time duration information of an adjacent base station, a frequency band measuring unit to determine first frequency band measuring information with respect to a first frequency band used by the adjacent base station based on the first quiet time duration information, a frequency band exchange-determining unit to determine whether to exchange frequency bands with each other based on the first frequency band measuring information, and a transmitting unit to transmit data to a terminal using the first frequency band according to the determined result.
