Abstract
In a communication system that includes a control station and dependent stations, the control station broadcasts data intended for the dependent stations on a per-superframe basis. The dependent stations relay the data received from the control station among themselves. If a dependent station has received the data transmitted from the control station, the dependent station transmits an acknowledgement response. If a dependent station does not receive an acknowledgement response from another dependent station, then the dependent station relays the data intended for the other dependent station.
