Abstract:
1. A terminal data receiving method for a base station in a wireless communications system, the method comprising: estimating by a channel estimation unit of the base station a wireless channel state from a plurality of relay antennas in a relay to a plurality of base station antennas in a base station; generating by the channel estimation unit of the base station a channel state matrix based on the estimated wireless channel; transmitting by a transmitting unit of the base station base station data to the relay via the plurality of base station antennas; receiving by a receiving unit of the base station a sum of the base station data and terminal data transmitted from a transmission terminal selected from among a plurality of terminals connected to the relay based on a wireless channel from the plurality of relay antennas to the plurality of base station antennas; and decoding by a decoding unit of the base station the terminal data based on the channel state matrix.
