WIRELESS BASE STATION AND TERMINAL EQUIPMENT

It is an object to provide a wireless base station and a terminal equipment capable of shortening the processing time by not requiring the detection of the spatial correlation coefficient, which is required in general technology, and simplifying the selection process for terminal equipments to be connected to each other in a wireless base station that performs spatial multiplexing transmission to a plurality of terminal equipments and a terminal equipment responding for spatial multiplexing transmission. A terminal equipment 12 includes an interference cancellation capability information data maintaining section 20 that maintains interference cancellation capability information data indicating the interference cancellation capability of the terminal equipment 12 and signals the interference cancellation capability information data to a wireless base station 1. The wireless base station 1 includes a control signal extracting unit 3 and a spatial multiplexing controller 4, and the spatial multiplexing controller 4 selects one or more terminal equipments 12 for spatial multiplexing connection on the basis of the interference cancellation capability information data extracted from a reception signal from the terminal equipment 12.
