A study on dynamic antenna clustering for distributed MIMO cooperative wireless access network

Abstract (in Japanese) (See Japanese page) 
(in English) In the distributed MIMO cooperative wireless access network, the area spectrum efficiency can be improved by constructing a number of clusters in a macro-cell. However, this results in large inter cluster interference (ICI) from neighbor clusters and degrades the received signal-to-interference plus noise power ratio (SINR) for user equipment (UE) at a cluster boundary (namely, cluster-edge UE).
In this paper, we propose a dynamic antenna cluster control which switch the boundary of clusters in a macro-cell in order to mitigate the probability of worst UE condition such as receiving the large interference from neighbor clusters. The dynamic antenna cluster control can switch the cluster-edge UE to the cluster-center UE by switching the boundary of clusters. By switching the cluster boundaries, the UE link capacity can be averaged between the worst UE condition and the best UE condition.
We evaluate, by computer simulation, the UE link capacities of static antenna cluster and dynamic antenna cluster control. It is shown that the proposed dynamic antenna cluster control improve the UE link capacity about 1.5 times in the median of cumulative distribution function (CDF).
