Abstract (in Japanese) (See Japanese page) 
(in English) With the demanding of higher capacity and higher data rate services in 5G-advanced systems, distributed multi-user multiple-input multiple-output (MU-MIMO) is a promising approach for radio access network (RAN). To avoid a prohibitively high signal processing complexity required for large-scale MU-MIMO, we have been studying cluster-wise distributed MU-MIMO for 5G advanced RAN. Multiple clusters are formed in each cell by K-means algorithm using user locations information. Unfortunately, cluster-wise distributed MU-MIMO introduces the inter-cluster-interference, thereby degrading the link capacity. In order to mitigate the capacity reduction, we recently proposed a sum capacity maximization-based power allocation strategy assuming an unrealistic square-shaped cellular structure.
It should be noted that the cluster shape may be different for a different cellular structure, resulting in a different inter-cluster interference. The aim of this paper is to evaluate the impact of sum capacity maximization-based power allocation strategy in the case of a realistic cellular structure. In this paper, a previously proposed modified K-means based cellular structuring method using antenna locations is considered. The link capacity evaluation is carried out by computer simulation assuming both the close-to-realistic cellular structure and the simple but unrealistic square-shaped cellular structure. It is shown that our previously proposed optimal power allocation strategy can effectively improve the link capacity even in the case of the close-to-realistic cellular structure.
