In this paper, we propose a concept of a scalable and reconfigurable distributed multiuser MIMO (MU-MIMO) system and an interference coordination for ultra-dense radio access network (RAN). With careful consideration of the feasible radio signal processing capability for MU-MIMO, the communication service area is divided into a number of disjointed small areas (cells), each being formed based on the distributed antenna location information, and then, users in each cell are grouped into multiple user-clusters based on the user location information. In order to improve the spectrum efficiency, small-scale cluster-wise distributed MU-MIMO signal transmission is performed in parallel by reusing the same frequency in all user-clusters in all cells. However, in return, the strong interference is produced and this limits the improvement of system capacity. Hence, the introduction of interference coordination is essential. We evaluate the user capacity by computer simulation to show the effectiveness of the proposed scalable and reconfigurable distributed MU-MIMO system and interference coordination.
