Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes a scalable network-assisted full-duplex (NAFD) cell-free massive MIMO (CF-mMIMO) system that achieves high spectral efficiency while reducing the fronthaul load by access point (AP) clustering for each uplink and downlink. Specifically, we propose AP clustering techniques based on convex optimization and combinatorial optimization, along with transmit power control suitable for AP clustering. Numerial results demonstrate that our proposed approach achieves high spectral efficiency compared to conventional methods under fronthaul capacity limitations.
