| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper enhances our previously reported simple decentralized cell association method for heterogeneous networks, where low transmission-power pico or femto base stations (BSs) are overlaid onto a high transmission-power macro BS, to reduce the occurrence of ping-pong handover. 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 assisted by a small amount of broadcast information from the respective BSs. The extended algorithm improves the convergence property by applying low-pass filtering to the allowable bandwidth for newly added users which is broadcasted by each BS. The proposed method can be applied to the case with inter-cell interference coordination (ICIC) through the use of protected radio resources exclusively used by the pico/femto BSs. From the numerical results, we show that by using the proposed low-pass filtering, the occurrence probability of ping-pong handover is reduced without decreasing the achievable geometric mean user throughput. We also 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. | |
