Abstract (in Japanese) (See Japanese page) 
(in English) With the purpose of improving the performance of next generation wireless networks, cooperative relaying (CoR) and network coding (NC) are promising techniques for bi-directional or two-way transmission.
Network coding can reduce the number of bi-directional transmission slots compared to CoR, which results in higher total throughput enhancement. However, the asymmetric traffic condition has significant impact on the bi-directional throughput of NC. In order to improve the throughput of NC even under asymmetric traffic condition, two opportunistic hybrid NC and CoR schemes are proposed in the present paper. In the proposed schemes, adaptive time resource allocation is realized for each transmission protocol, and the impact of the traffic ratio and the relay position on the throughput is investigated. Simulation results reveal that the proposed schemes not only achieves higher throughput than the conventional scheme but are also robust against asymmetric traffic conditions.
