Abstract (in Japanese) (See Japanese page) 
(in English) In the terminal coordination wireless communication system, neighboring terminals share transmission
information to collaborate with each other, forming a virtual large-scale Multiple-Input Multiple-Output (MIMO) to
realize spatial multiplexing transmission. This study employs millimeter-wave communication, which is capable of
high-speed and low-latency information transmission, for sharing information with neighboring terminals. This study
aims to evaluate the performance of inter-terminal access control in a millimeter-wave-based terminal coordination
wireless system. To enhance the efficiency of the virtual MIMO through terminal coordination, it is necessary to share
the transmitted information with as many terminals as possible. At first, an evaluation of uplink performance using
the Sub-6 GHz band is conducted with a simplified access control mechanism. Furthermore, the significant impact of
spatial correlation in environments with high terminal density is confirmed, and different uplink transmission meth
ods to mitigate this effect are compared. The results demonstrate that the proposed transmission method effectively
suppresses spatial correlation and enhances communication performance.
