Title: Innovations by Tatsuki Okuyama: Pioneering Patents in Communication Technology
Introduction
Tatsuki Okuyama is a renowned inventor based in Tokyo, Japan, with a remarkable portfolio of 17 patents. His work predominantly focuses on enhancing communication technology, specifically in addressing the challenges related to user terminals in varying states of movement and stillness.
Latest Patents
Okuyama’s latest patents reflect his commitment to improving communication systems. One of his significant innovations is a base station and transmission method designed to prevent deterioration in communication characteristics. This method incorporates scheduling that considers whether user terminals are in motion or at rest. By utilizing a received-power measurement section, the system measures the power of a reference signal originating from each user terminal. The movement/stillness determination section then identifies if each terminal is moving or unmoving based on variations in received power over time. A group selection section further categorizes the terminals, enabling optimized signal transmission strategies—utilizing either open-loop signal processing without precoding for moving terminals or closed-loop signal processing with precoding for unmoving terminals.
In addition, Okuyama has developed a base station communication method whereby a control unit allocates a common downlink reference signal based on an estimated Doppler shift derived from an uplink reference signal. This method ensures effective signal transmission across multiple beams, reinforcing the reliability and efficiency of communication systems.
