Abstract (in Japanese) (See Japanese page) 
(in English) Interworking among heterogeneous wireless networks across licensed and unlicensed bands has gained much attention to support the surge in mobile traffic. In unlicensed bands, the dominant wireless network application is wireless LAN (WLAN) where frequency resources are shared based on carrier sense multiple access/collision avoidance (CSMA/CA). When the mobile traffic starts to overwhelm the wireless resources, the throughput of some users will be significantly degraded by the hidden terminal problems created by radio environment asymmetry around the transmitter and receiver. In this paper, we propose a access opportunity acquisition scheme for unlicensed band systems by using the licensed band access. Computer simulations show that the proposed scheme outperforms the throughput of the transmission with RTS/CTS when the wireless resource is depleted by the transmission of terminals hidden from the transmitter.
