Abstract
This paper shows a Self-organizing networks (SON) algorithm for interference coordination in downlink Orthogonal Frequency-Division Multiple Access (OFDMA) networks. A distributed algorithm is introduced with a proof of convergence for a static user population. The algorithm uses closed-form formulas for the transmit powers update, and is therefore computationally light. The proposed algorithm is applied to a 117 cells dynamic network simulator with a File Transfer Protocol (FTP) service, showing significant performance gains over a Reuse 1. The Quality of Service (QoS) of cell-edge users improves without degrading the QoS of other users. The trade-off between Block Call Rate (BCR), which is the proportion of users rejected by admission control, and cell-edge users throughput is shown, and a simple method for the network operator to manage it is provided.
