Method for assigning channels based on spatial division multiplexing in an orthogonal frequency division multiplexing system with multiple antennas다중 안테나를 가진 직교 주파수 분할 멀티플렉싱 시스템에 있는 공간 분할 멀티플렉싱을 기반으로 하는 할당되는 채널에 대한 방법
A method for assigning a single frequency sub-channel to a plurality of MSs (Mobile Stations) in an OFDM (Orthogonal Frequency Division Multiplexing) system utilizing SDM (Spatial Division Multiplexing) with multiple transmit/receive antennas. In the method, a BS (Base Station) can effectively assign a pilot channel to estimate a downlink channel. The BS divides the single frequency sub-channel into a plurality of spatial channels, and sequentially assigns the plurality of spatial channels to the MSs having the maximum communication capacity, thereby transmitting signals of the MSs through the single frequency sub-channel.
