Abstract: PURPOSE: A feedback controller of a MIMO communications system for obtaining an excellent transmission rate performance is provided to operate the communications system based on an MC system. CONSTITUTION: A first effective SNR(Signal to Noise Raito) calculator(222) calculates per-layer effective SNR after multiplexing a pre-coding matrix and a receive channel matrix based on a MC(Multiple Codewords) system. A first transfer rate calculator(226) calculates a first transmission rate. A second transfer calculator calculates the effective SNR after multiplexing the pre-coding matrix and the receive channel matrix based on a SC(Single Codewords) system(230).

Abstract: PURPOSE: An apparatus and a method for determining a channel state indicator in a mobile communication system are provided to perform efficient AMC(Adaptive Modulation And Coding) scheduling which is matched with a channel condition through a simple additional operation process by using a mean square channel matrix method. CONSTITUTION: A terminal receives signals(701). The terminal estimates a channel matrix by using a reference signal from the received signals(703). The terminal outputs a predetermined value(705). The terminal calculates a mean value by leveling a value outputted from the former step(707). The terminal determines a predetermined target value by applying an equation based on the calculated value(709, 711).
