Abstract (in Japanese) (See Japanese page) 
(in English) Compared with the traditional cellular structure based on centralized antennas, the distributed antenna-based cellular structure has advantages in terms of low latency, high capacity, and low energy consumption. Especially when using the millimeter wave bands, it can effectively reduce the signal blockage problem frequently encountered in urban areas. Therefore, it can be considered as a promising cellular structure for 5G-advanced systems. The system performance may be strongly affected by the cellular structure. So, how to construct base station coverage areas called cells is quite important. In this paper, we propose a cellular structure method by modified K-means clustering algorithm to construct a given number of cells each having the same number of distributed antennas. It is shown by the computer simulation that, compared with cellular structures of simple square-shaped cells and that constructed by an original K-means algorithm, the proposed cellular structure method achieves higher link capacity, higher fairness of user capacity, and lower delay when user scheduling is considered.
