In this paper, we propose a distributed adaptive interference coordination algorithm for a practical orthogonal frequency division multiple access (OFDMA)-based mobile cellular systems. The designed algorithm can achieve an efficient frequency reuse for any user distribution and traffic load. Since no a priori frequency planning is required, the minimal coordination between base stations is also achieved...
This paper describes the optimization of the frequency allocation in the downlink of an Orthogonal Frequency Division Multiple Access (OFDMA) cellular network by means of centralized adaptive frequency management. The adaptive frequency allocation is performed off-line based on a Genetic Algorithm (GA) which computes for each cell an optimal number of radio resource blocks as guided by the geometry...
