<P>PROBLEM TO BE SOLVED: To provide a wireless communication system configured for signal communication with both or either of a user device and a base station, and to improve the transmission efficiency of the wireless communication system. Ž<P>SOLUTION: The wireless communication system has one or more base stations, a first group of relay stations, and a second group of relay stations in which the base station can have one or more antennas for signal communication, a transceiver, and a communication controller. The communication controller is constituted to control one or both the signal transmission power of at least one antenna and the signal communication timing of at least one antenna. The communication controller divides a service term of the antenna into a plurality of stages and operates to make a signal transmitted to or transmitted from a first group of relay stations at a first stage communicative. The communication controller also operates to allow a relay station in a second group of relay stations to perform signal communication with either or both a user device and a base station at least in a partial period of the first stage regardless of a signal transmitted to or from the first group of relay stations.
