Block Diagonalization is employed for the coordinated users within the cluster to remove interference, while the interference from non-coordinated users remains. The achievable rate is evaluated resorting to an analytical expression conditioned on the position of the users in the cluster. A partial coordination approach is proposed to reduce the coordination complexity and overhead, where users close to the base station are not coordinated. Two approaches are considered, namely the non-coordinated users can be grouped and assigned separated resources from the coordinated ones, or they can be mixed.6application/pdfeng© 2013, IEEECoordinated base stationsClustering; multiple-antennasBlock diagonalizationNetwork MIMOconference paperTelecomunicaciones10.1109/WCNC.2013.6555065open access31463151IEEE Wireless Communications and Networking Conference ( 2013)CC/0000021490
