Abstract (in Japanese) (See Japanese page) 
(in English) This paper extends our previously reported simple decentralized cell association method for heterogeneous networks (HetNet), where low transmission-power pico or femto base stations (BSs) overlay onto a high transmission-power macro BS, to achieve faster convergence of cell association for all users according to the user location distributions. In the proposed method, an appropriate cell association for all users within a cell is achieved in an iterative manner based on the feedback information of each individual user regarding the throughput gain by connecting new BS assisted by a small amount of broadcast information from the respective BSs about the allowable resource allocation and multiuser diversity gain. The extended algorithm allows for simultaneous handovers of multiple users to the same BS for faster convergence of cell association for all users according to the user location distributions. From the numerical results, we show that the proposed method adaptively achieves better cell association for all users according to the user location distributions compared to the conventional cell range expansion (CRE) method. And it can be achieved in fewer iterations compared to previously reported simple decentralized cell association method.
