Abstract(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, for accommodating the case with inter-cell interference coordination (ICIC) between macro and pico/femto BSs. Here we assume the ICIC through the use of protected radio resources exclusively used by the pico/femto BSs. The focus of this investigation is on the downlink and the purpose of the cell association is to achieve better user fairness, in other words, to increase the minimum average user throughput (worst user throughput). 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 proposed method does not require cooperation between BSs. In the case with ICIC, the proposed method The proposed cell association method determines not only the BS to be connected but also the used resource type (whether protected or non-protected) for the respective users. Based on 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. The advantage of the proposed method over the CRE is further enhanced in an ICIC scenario. |
