Abstract (in Japanese) (See Japanese page) 
(in English) Transmission scheduling in cooperative relaying is studied for achieving high spectral efficiency, assuming that cooperative relaying consists of single source, destination and relay station. Transmission scheduling, which allows the route with good channel conditions to transmit the data, would lead to higher utilization of wireless resources such as power and frequency. However, some transmitters of cooperative relaying transmit the data to more than one receiver and thus the utilization efficiency of wireless resources can vary according to which link is used for transmission scheduling. In this paper, the spectral efficiency of cooperative relaying is theoretically derived in the condition that a source transmits the data when the instantaneous channel gain of any link is higher than the threshold value. Then, it is shown that high spectral efficiency can be achieved when the channel gain of some links along the route are high.
