Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose a packet scheduling algorithm which selects an appropriate user relay and transmission rate in response to variation of channel quality and packet delay. In the relaying cellular networks, mobile users are equipped with not only cellular but also user relaying radio interfaces, where base station maintains data transmission by using finite buffer queue for each user. Our proposed algorithm selects a user with good cellular channel condition as a relay station for a mobile user with bad cellular channel condition, and can achieve flexible packet scheduling by adjusting transmission rates of cellular link between the base station and the relay station as well as a relay link between the relay station and the mobile station by considering their requirements and channel conditions. The performance results obtained by computer simulation show that the proposed scheduling algorithm is able to achieve high network capacity, low packet loss and good traffic balance among mobile users.
