Abstract(in English) | This paper presents our previously reported user association method to maximize the downlink system throughput in a cellular network, where the system throughput is defined based on (p, α)-proportional fairness. The proposed method assumes a fully decentralized approach, thus complicated inter-base station (BS) cooperation is not required. In the proposed method, each BS periodically and individually broadcasts supplemental information regarding the bandwidth allocation to newly connected users. Assisted by this information, each user calculates the expected throughput that will be obtained by connecting the respective BSs. Each user terminal feeds back the metric for user association to the temporally best BS, which represents a relative increase in throughput through re-association to that BS. Based on the reported metrics from multiple users, each BS individually updates the user association. The proposed method gives a general framework for optimal user association for (p, α)-proportional fairness-based system throughput maximization and is especially effective in heterogeneous cellular networks where low transmission-power pico BSs are overlaid onto a high transmission-power macro BS and different frequency bands with different frequency bandwidths may be assigned to different BSs. Computer simulation results show that the proposed method maximizes the system throughput from the viewpoint of the given (p, α)-proportional fairness. |
