COMMUNICATION SYSTEM, DEPENDENT STATION THEREOF AND DEPENDENT-STATION RELAY TRANSMISSION METHOD
First Claim
1. A communication system in which a control station broadcasts data is intended for a plurality of dependent stations, on a per-superframe basis, each of the plurality of dependent stations comprising:
- a receiving unit that receives data broadcast from the control station in an Nth (where N is an integer) superframe;
a transmitting unit that transmits an acknowledgement response that indicates a reception condition of the data, in a time slot that has been allocated to the dependent station in the Nth superframe; and
a relaying unit that relays, in accordance with the an acknowledgement response transmitted from another dependent station, data intended for the other dependent station in a time slot that has been allocated to the dependent station in an (N+1)th superframe.

Abstract
In a communication system comprising a control station (101) and a plurality of dependent stations (102, . . . , 105), the control station (101) broadcasts data intended for the plurality of dependent stations (102, . . . , 105) on a per-superframe basis. The plurality of dependent stations relay the data, which has been received from the control station (101), among themselves. If a dependent station (102) has received the data transmitted from the control station (101), this dependent station (102) transmits an acknowledgement response. If a dependent station (102) does not receive an acknowledgement response from another dependent station (103), then this dependent station (102) relays the data intended for this other dependent station (103).
