INTERACTION METHOD BETWEEN ARQ AND HARQ FOR THE SYSTEM WITH LONG ROUND TRIP DELAY
摘要
PURPOSE: A method for interaction between ARQ and HARQ of a system with a long shuttling delay time is provided to quickly cope with a transmission error by re-transmitting a packet of a window on standby when an error in which NACk of HARQ is mistaken for ACK occurs. CONSTITUTION: A transmission buffer(210) and a transmit window are influenced by the HARQ feedback information. A buffer on standby(220) and an window on standby are influenced by a status report information packet(230). The buffer on standby detects an error in which NACK is recognized as ACK in HARQ. The buffer on standby re-transmits the packet of the buffer on standby by receiving feedback information concerning the error.
