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).
