초록
A control apparatus for use in wireless communications includes an antenna unit having antennas, the number of the antennas being equal to a maximum allowable number of connections in a specific frequency band; and a controller for receiving a connection request signal from each terminal attempting to connect to the control apparatus via the antenna unit, and transmitting and receiving a data signal to and from each terminal connected to the control apparatus by using a multiple-input-multiple-output scheme. The controller transmit and receive the data signal to and from each terminal connected to the control apparatus by obtaining a signal value of each antenna based on a predicted channel matrix and the number and types of terminals connected to the control apparatus via the antenna and separating the data signal for each terminal from the signal value according to the multiple-input-multiple-output scheme.
