Patent number: 8406250Abstract: A medium access control method is provided in which a control station transmits one specific frame to terminal stations, thereby arranging a schedule of a data transmission time of the control station and each of the terminal stations and allowing a time zone unused by a station for data transmission to be allocated to another station. The control station transmits a schedule frame having defined therein a time occupied by each of the terminal stations, thereby reducing overhead. Also, the completion of the preceding communication performed by another station is detected, thereby effectively using an idle time of a medium and improving transmission efficiency.Type: GrantFiled: September 1, 2010Date of Patent: March 26, 2013Assignee: Panasonic CorporationInventors: Gou Kuroda, Akio Kurobe, Koji Ikeda, Kensuke Yoshizawa
