Evolution-Advanced (LTE-A) heterogeneous networks (HetNets),
enhanced inter-cell interference coordination (eICIC) and further
eICIC (FeICIC) have been proposed by LTE standardization
bodies to address the entangled inter-cell interference and the
user association problems. We propose the distributed algorithms
based on the exact potential game framework for both eICIC
and FeICIC optimizations. We demonstrate via simulations a
64% gain on energy efficiency (EE) achieved by eICIC and
another 17% gain on EE achieved by FeICIC. We also show
that FeICIC can bring other significant gains in terms of
cell-edge throughput, spectral efficiency, and fairness among
user throughputs. Moreover, we propose a downlink scheduler
based on a cake-cutting algorithm that can further improve
the performance of the optimization algorithms compared with
conventional schedulers.
