Abstract

In this paper, we consider frequency planning of orthogonal frequency division multiple access (OFDMA) based cellular networks, with two-hop decode-and-forward relay stations (RSs). We develop a new framework for the mathematical modeling of the frequency planning problem, which aims at suppressing multi-links interference and enhancing spectral efficiency. The concept of incidence coloring from modern graph theory is utilized to recast the original frequency planning problem and guide the solution from graph theory perspective.
