MEDIUM ACCESS CONTROL IN MASTER-SLAVE SYSTEMS

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.
