Interference Avoidance through Dynamic Downlink OFDMA Subchannel Allocation using Intercell Coordination
Abstract- OFDMA subchannel allocation has been wellstudied. However, most of the available literature considers a single cell system without cochannel interference. We present a no...

Multicell Downlink OFDM Subchannel Allocations Using Dynamic Intercell Coordination
In this paper, we present a novel integer programming (IP) optimization formulation for downlink OFDM subchannel allocations in a multicell system and propose viable sub-optimal so...

Self-Organizing Dynamic Fractional Frequency Reuse in OFDMA Systems
—We describe an algorithm for sub-carrier and power allocation that achieves out-of-cell interference avoidance through dynamic fractional frequency reuse (FFR) in downlink of ce...

A Graph-Based Approach to Multi-Cell OFDMA Downlink Resource Allocation
— A novel, practical and low-complexity multi-cell OFDMA downlink channel assignment method using a graphbased approach is proposed in this work. The inter-cell interference (ICI...
