APPARATUS FOR TRANSMITTING TRANSMISSION RATE RELATED INFORMATION FOR RECEIVER SELECTION IN A MULTI CELL MULTIPLE INPUT MULTIPLE OUTPUT (MIMO) DOWNLINK NETWORK AND A METHOD THEREOF, A RECEIVER SELECTION APPARATUS IN THE MULTI CELL MIMO DOWNLINK NETWORK AND A METHOD THEREOF AND A SYSTEM THEREOF, CAPABLE OF ACHIEVING HIGH SUM TRANSMISSION RATE
PURPOSE: An apparatus for transmitting transmission rate related information for receiver selection in a multi cell MIMO downlink network and a method thereof, a receiver selection apparatus in the multi cell MIMO downlink network and a method thereof and a system thereof are provided to transmit the transmission rate related information for receiver selection in the multi cell MIMO downlink network which can achieve maximum sum transmission rate by calculation of low complexity only.;CONSTITUTION: A receiving part (410) receives a pilot signal from a transmitter. A calculation part (420) calculates approximated sum transmission rate information by assuming a nonlinear receiver on the basis of the received pilot signal. The calculation part calculates the approximated sum transmission rate, by assuming the nonlinear receiver on the basis of the sum of variation matrix of other receivers existing in a currently belonging receiver group and variation matrix of a self-designated signal. A transmission part (430) transmits the approximated sum transmission rate information to the transmitter.;COPYRIGHT KIPO 2013;[Reference numerals] (410) Receiving part; (420) Calculation part; (430) Transmission part; (440) Communication execution part
