“…Many algorithms have been previously proposed to solve resource allocation (RA) problem on a sub-channel basis [3,4]. However, RA on a sub-channel basis has two main drawbacks; higher complexity and large amount of channel information to be fed-back to the base-station (BS).…”

Resource allocation (RA) in multi-cell OFDMA systems is very important for maximizing system throughput. Although sub-channel RA is optimal in terms of system throughput, more interest is given to chunk-based RA to simplify RA algorithms and minimize required signalling. In this paper, we propose a fairness-aware chunk-based RA algorithm for the downlink transmission of multi-cell OFDMA system with fractional frequency reuse (FFR) adoption. Simulation results reveal that our proposed algorithm outperforms two reference algorithms in the literature in terms of some system metrics such as average spectral efficiency (SE), users' fairness and cell-edge users' rates.

“…These sub-problems should be jointly and efficiently solved with reasonable complexity. Many algorithms in the literature have been proposed to solve RA problem on a a sub-channel basis [3], [4] either to maximize system throughput or minimize transmitted power. RA on a subchannel basis has two main drawbacks: (1) RA algorithm complexity highly grows as number of sub-channels increases and (2) large signalling is required to be fed-back about channel information of each sub-channel.…”

Resource allocation (RA) in multi-cell OFDMA systems is very important for maximizing system throughput. Although sub-channel RA is optimal in terms of system throughput, more interest is given to chunk-based RA so as to simplify allocation algorithms and minimize required signalling. In this paper, we propose a fairness-aware chunk-based RA algorithm for the downlink transmission of multi-cell OFDMA system with fractional frequency reuse (FFR) adoption. Simulation results reveal that our proposed algorithm outperforms two reference algorithms in literature in terms of some system metrics such as average system spectral efficiency (SE), users fairness and rates of cell-edge users.
