Enhancing cell edge users performance in open access small cells networks: A Cross layer approach

In the mobile access network, the cell edge users are significantly affected by inter-cell interference. Exploiting the proximity of all entities (transmitters and receivers) in small cells networks, we propose different schemes that enhance the cell edge users rate to at least double of the existing rates, and substantially reduce the average packet delay. The access points (APs) decide their transmission types by solving a common problem that does not need any inter-AP information exchange. To ensure a better performance in terms of packets delays, an upper layer information has been taken into account. We start the discussion with a simple model, then we extend it to a more general and realistic model. Extensive simulation results are presented to show the effectiveness of the proposed schemes.
