N2 - The ultra-dense radio access network (RAN) consisting of a large number of distributed antennas and user terminals is considered to improve link capacity and coverage while saving the energy consumption for 5G advanced systems. Because of such a large-scale multi-user multiple-input multiple-output (MU-MIMO), the computational complexity of signal processing is difficult to realize. Aiming to reduce the computational complexity to an acceptable level, the clustering approach is promising to decompose the large-scale MU-MIMO into several smaller-scale ones. K-means clustering is introduced to form either user clusters or antenna clusters and then, cluster member assignment (CMA) is done to perform cluster-wise zero-forcing (ZF) based MU-MIMO. In this paper, we compare through computer simulation possible combinations of two clustering methods and two CMA methods in terms of achievable link capacity.
