Abstract (in Japanese) (See Japanese page) 
(in English) We proposed a multiple access points (APs) simultaneous transmission technique which APs transmit to their own station (STA) while mitigating inter-cell interference by extending precoding weight of multi-user MIMO transmission. In the proposed technique, a lot of overhead are required because the channel state information (CSI) for transmission weight calculation. As a result, the frame efficiency is degraded. In this paper, we propose the multiple APs simultaneous transmission technique with the implicit feedback beamforming that can achieve beamforming without feedback of CSI for the overhead reduction. Then this paper indicates its effectiveness by using MIMO channel measured in indoor environment.
