It may offer a high gain in capacity through interference mitigation. This however, comes at a cost of high information exchange between cooperating entities and a high computational burden. Clustering of base stations into subgroups is an alternative to guarantee such cooperation benefits in a lower scale. The optimal definition of clusters, however, and a systematic way to find a solution to such problem is not yet available. In this work, we highlight the combinatorial nature of the problem, exploit this to describe the system of users and base stations as a graph and formulate a pure 0-1 program. Its solution suggests a cost optimal way to form clusters and assign user subsets to them.}, language = {en} } @misc{GiovanidisPulaj, author = {Giovanidis, Anastasios and Pulaj, Jonad}, title = {The Multiperiod Network Design Problem: Lagrangian-based Solution Approaches}, url = {http://nbn-resolving.de/urn:nbn:de:0297-zib-13367}, number = {11-31}, abstract = {We present and prove a theorem which gives the optimal dual vector for which a Lagrangian dual problem in the Single Period Design Problem (SPDP) is maximized.
