Context-aware Radio Resource Management in HetNets

In order to address the rapid increase in data-rate requirements in existing and upcoming wireless communication systems, one solution is to add more base-stations to achieve increased spectrum reuse. A Heterogeneous Network (HetNet) - consisting of a deployment of a variety of different types of small cells in a cellular infrastructure - is one manifestation of that approach. In this HetNet case, Radio Resource Management (RRM) techniques are important to balance and optimize the radio resource allocation among users of different systems by avoiding or controlling the generated interference. This paper provides a concise description of the role of RRM techniques in HetNets by analyzing the criteria and tradeoffs that are assumed, and presents a framework for the exploitation of the available context information within the HetNet environment, that leads to optimized spectrum usage.
