| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | To enhance the throughput of OFDMA WLAN systems, this paper proposes a stations-clustering scheme in which stations in the same basic service set (BSS) are grouped into clusters. In the proposed scheme, initially, to obtain statistics required for calculating the achievable throughput when the stations are grouped into a certain clustered-pattern, the AP and all stations belong to the same cluster and transmit DATA frames for a certain period. After that, the AP calculates the achievable throughput for all clustered-pattern and chooses an optimum clustered-pattern that maximizes the achievable throughput. Then, the stations are grouped into clusters in accordance with the selected clustered-pattern, and the stations within the same cluster share the radio resource by an intra-BSS centralized OFDMA WLAN scheme. Since the proposed scheme reduces the signaling overhead due to the feedback of CSI and the number of exposed stations while obtaining higher multi-user diversity gain, throughput of OFDMA WLAN can be enhanced. Numerical simulation confirms that the proposed scheme can improve throughput performance by introduction of dynamic station clustering. | |
