A new channel access scheme to improve the throughput in the medium access control layer is proposed to support the high data rate of multiple users. The proposed scheme is based on access point-coordinated multiuser transmission via the adoption of a trigger frame. The total throughput of the proposed scheme is improved by up to 30% compared with the uplink-multiuser channel access scheme based on the request to send/clear to send exchange. Moreover, as the number of stations increases, the degree of improvement in performance increases.
