Medium access control method and system

摘要

A medium access control method is provided in which a control station 11 transmits one specific frame to terminal stations 21 through 2n, thereby arranging a schedule of a data transmission time of the control station 11 and each of the terminal stations 21 through 2n and allowing a time zone unused by a station for data transmission to be allocated to another station. The control station 11 transmits a schedule frame having defined therein a time occupied by each of the terminal stations 21 through 2n, 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.
