PROBLEM TO BE SOLVED: To reduce the time required for re-transmission, in wireless communication. SOLUTION: A communication system has a relay station apparatus and a transmission and reception station apparatus. The relay station apparatus generates a broadcast acknowledge packet including results of error detection carried out every for a packet received from each transmission and reception station apparatus, and transmits the generated broadcast acknowledge packet to each transmission and reception station apparatus. The transmission and reception station apparatus determines whether or not retransmission of the packet is required based on the received broadcast acknowledge packet. When determined that retransmission of the packet is required, the transmission and reception station apparatus transmits the packet to the relay station apparatus in the same time slot as the other transmission and reception station apparatus.
