BASE STATION DEVICE, RECEIVER DEVICE, COMMUNICATION METHOD AND COMMUNICATION SYSTEM

PROBLEM TO BE SOLVED: To obtain satisfactory frequency use efficiency if an SC-ASA method is applied to MIMO transmission.SOLUTION: A function g indicative of the presence/absence of signal transmission in the combination of an input antenna number and a subcarrier number is initialized (S1). Next, among functions f according to a communication volume, an element number of a matrix having a disposed element of a maximum value is extracted, to calculate x, y of an x-row and a y-column having the disposed maximum value element (S2), so that it is determined whether a transmission antenna already allocated to the y-th column of the function g is one or less (S4). In step S4, if it is determined to be one or less, and allocation is still possible (Yes in S4), it is set to be g(x,y)=1 in step S5. Then, the execution of allocation is reflected to the function g and it is determined whether the whole allocation is completed (S6).
