A communication method which transmits a control signal from a first communication apparatus to a second communication apparatus. The first communication apparatus executes retransmission processing where it repeatedly transmits a control signal until an acknowledgment signal is received or until predetermined termination conditions are satisfied. The second communication apparatus receives the control signal, transmits the acknowledgment signal to the first communication apparatus, and determines the start timing for control by the control signal based on a predetermined interval. |
