Abstract:
1. A communication system in which a control station broadcasts data intended for a plurality of dependent stations, on a per-superframe basis, each of the plurality of dependent stations comprising: a first receiving unit that receives data broadcast from the control station in an Nth (where N is an integer) superframe; a second receiving unit that receives a response that indicates a reception condition of the data on another dependent station; and a relaying unit that relays the data received by the first receiving unit to the other dependent station in a time slot that has been allocated to the dependent station in an (N+1)th superframe when the response received in an Nth superframe by the second receiving unit indicates that the other dependent station did not receive the data, and restricts to relay the data received by the first receiving unit to the other dependent station when the response received by the second receiving unit indicates that the other dependent station received the data.
