    <title language="eng">A 0-1 Program for Minimum Clustering in Downlink Base Station Cooperation</title>
    <abstract language="eng">Base station cooperation in the downlink of cellular systems has been recently suggested as a promising concept towards a &#13;
better exploitation of the communication system physical resources. It may offer a high gain in capacity through interference mitigation. &#13;
This however, &#13;
comes at a cost of high information exchange between cooperating entities and a high computational burden. &#13;
Clustering of base stations into subgroups is an alternative to  &#13;
guarantee such cooperation benefits in a lower scale. The optimal definition of clusters, however, and a systematic way to find a solution to &#13;
such problem is not yet available. In this work, we highlight the combinatorial nature of the problem, exploit this to describe the &#13;
system of users and base stations as a graph and formulate a pure 0-1 program. Its solution &#13;
suggests a cost optimal way to form clusters and assign user subsets to them.</abstract>
