ABSTRACT:
The present invention relates to a frame transmission scheduling method of a wireless communication considering frame transmission delay time information. The present invention provides a wireless communication system, which comprises a transmitting station for storing a transmission time in a transmission frame, calculating a delay time using the transmission time when retransmission of the transmission frame is requested, and scheduling the transmission of the transmission frame using the delay time; and a receiving station for transmitting a response frame (ACK frame) to the transmitting station when receiving the transmission frame. According to the present invention so configured, since transmission delay time information of a frame is considered when scheduling a sequence of frame transmission, there is an advantage in that waste of wireless resources due to retransmission delay of frames can be prevented.
