This paper enhances 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 aim of this investigation is to improve the convergence rate of the iterative algorithm. The proposed method assumes a fully decentralized approach, which is practical in the real system as cooperated 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 which will be obtained by connecting respective BSs. Each user terminal feeds back the metric for user association to the temporally best BS, which represents the 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. In the enhanced method proposed in the paper, we apply low-pass filtering to the supplemental information regarding the bandwidth allocation for newly added users and allow for the update of association of multiple users simultaneously with threshold-based decision. We show through computer simulation that the proposed method improves the convergence rate of the original method while avoiding the oscillation of user association after sufficient number of iterations in algorithm, which means the avoidance of the ping-pong handovers. |
