Fair resource allocation for OFDMA multi-cell networks

Abstract

Fair resource allocation in OFDMA networks is studied in this paper. We propose a distributed algorithm requiring minimum inter-cell information that embodies the principle of balancing advantaged and disadvantaged user traffic flows. A simple interference deterministic channel model assuming zero queuing delay is used. We propose a hybrid power and bandwidth allocation algorithm. A two-dimensional simulation conducted on both uniform and random-sized-cells shows the benefits are significant when fair allocations are desired.
