Abstract
A wireless communication apparatus, for example a wireless base station that spatially multiplexes data for transmission, includes plural array antennas and a beam shape controller that controls the array antennas to form beams of different shapes and each transmit signals for communication quality measurement in an area to be covered by the apparatus, and determines an initial value of a beam shape to be used in data transmission to a counterpart device that has received the signal for communication quality measurement, and after the initial value is determined, repeatedly executes processing to control the array antennas to tentatively change a beam shape in use in data transmission to the counterpart device, and redetermine a beam shape to be used in data transmission to the counterpart device, based on communication quality measured when the post-tentative-change beam shape is used and communication quality measured when the pre-tentative-change beam shape is used.
