ABSTRACT:
The present invention relates to a wireless communication system that performs data communication using a spatial multiplex transmission scheme. A mobile station includes a transmission weight calculating unit that calculates a transmission weight and a beam information notifying signal generating unit that transmits a known signal for generating partial space information at a base station side. A base station includes a scheduling unit (DL spatial scheduling unit (17), UL spatial scheduling unit (18), and beam information notifying signal response vector estimating unit (20)) that generates the partial space information based on a received first known signal, and performs downstream scheduling and upstream scheduling based on the partial space information, and a scheduling result transmitting unit (UL control information generating unit (14) and transmission weight calculating unit (19)) that transmits a packet including an upstream scheduling result.
