Abstract:
1. A relay, comprising: a channel estimation unit to estimate a wireless channel state from a plurality of transmission antennas in a base station to a plurality of receiving antennas in the relay, and to generate a channel state matrix based on the estimated wireless channel state; a transmission terminal selection unit to select at least one transmission terminal based on the channel state matrix from among a plurality of terminals connected to the relay; a receiving unit to generate a received vector including terminal data received from the at least one transmission terminal and base station data received from the base station; a decoding unit to decode a sum of the terminal data and the base station data based on the channel state matrix and the received vector; and a transmission unit to transmit the decoded sum of the terminal data and the base station data to both of the base station and the transmission terminals.
