We propose a coordinated inter-cell resource allocation (CICRA) approach that can reuse efficiently the radio spectrum through inter-cell interference (ICI) management over a cluster of adjoining cells in some coordinated manner. In this, the entire radio spectrum is assigned to all the cells within the cell cluster. We use a set of coordinated cell-specific resource allocation sequences in order to manage ICI. The set of sequences should be designed and assigned in a coordinated manner over all cells within the cell cluster, so that ICI from nearer interfering cells could be preferentially avoided and the average ICI level according to the loading factor (LF) could be monotonic and minimally incremented. By the virtue of such ICI-managing mechanism, the CICRA approach can govern efficiently the average ICI level only through individual resource allocation without intervention among cells. In this paper, we would apply the CICRA approach to orthogonal frequency division multiple access (OFDMA) cellular systems. A system-level simulator for an OFDMA cellular system covering surrounding cells up to 3rdtier has been implemented. Simulation results show that the proposed CICRA approach can improve noticeably the system performance in terms of both the outage probability and spectral efficiency as compared with the classical UFR scheme and the soft frequency reuse (SFR) scheme over the entire LF range.
