Abstract (in Japanese) (See Japanese page) 
(in English) To enhance the throughput of wireless local area network (WLAN) while satisfying quality of service (QoS) requirements, Intra-BSS (Intra-Basic Service Set) centralized WLAN system has been proposed. In the system, channel and traffic state information (CTSI) of all associated stations are gathered at the access point (AP) by exchanging request-to-send (RTS) / clear-to-send (CTS) frames between AP and all associated stations, and the AP dynamically allocates reserved radio resource to the active stations based on their CTSI. However, since the exchanges of RTS/CTS frames are originally used for the reservation of radio resource, these frames should be transmitted with the lowest transmission rate, and the exchanges of RTS/CTS frames between AP and all associated stations incurs signaling overhead. To counter this problem, this paper proposes an efficient resource reservation scheme for intra-BSS centralized WLAN. In the proposed scheme, the AP exchanges RTS/CTS frames with a minimum number of stations required to reserve the radio resource for their exclusive use, and the other associated stations notify their CTSI using an adaptive modulation and coding (AMC) scheme. Since the period required to reserve the radio resource and gather the CTSI of all associated stations are shortened, the signaling overhead can be reduced. Numerical simulation confirms that the proposed scheme enhances the throughput of intra-BSS centralized WLAN.
