Abstract(in English) | Ultra-dense radio access network (RAN) consisting a large number of distributed antennas and user terminals is able to improve the capacity and coverage while saving transmission power in the 5G advanced systems. In order to alleviate computational complexity problem for large-scale multi-user multi-input multi-output (MU-MIMO) signal processing, user or antenna-based clustering is promising, in which a large-scale MU-MIMO is decomposed into many cluster-wise small-scale MU-MIMO. In each cluster, zero-forcing (ZF) precoding is utilized to eliminate inter-user interference (IUI). For the cluster-wise MU-MIMO, user-antenna association has a great impact on the link capacity. Previously, we proposed a distance-based user-antenna association method, but it has some flaws. In this paper, we propose other two methods to improve it. We adopt the well-known K-means clustering method. Two proposed methods are evaluated by achievable link capacity through computer simulation and are compared by heatmap in detail. |
