Abstract:
1. A wireless communication apparatus comprising: a transmitting device configured to transmit a plurality of aggregation frames to a destination terminal in respective frame exchange sequences, the aggregation frames each including a plurality of media access control (MAC) frames and frame identification information including frame lengths of the plurality of MAC frames; a receiving device configured to receive an acknowledgement frame of the aggregation frames transmitted from the destination terminal; a control device including a timer which sets a first lifetime for each of the frame exchange sequences at a time of starting transmission of the aggregation frames, and measures remaining time, the control device being configured to: a transmission data management device configured to determine whether or not to discard the MAC frame which has failed in transmission, based on a second lifetime or a retransmission count which are managed in units of one MAC frame, wherein when it is determined from the remaining time of the first lifetime that it is impossible to transmit the second one of the aggregation frames, the control device interrupts processing for retransmission of the MAC frame which has failed in transmission, and causes the transmitting device to transmit a third one of the aggregation frames to one of the destination terminal and another destination terminal, and when the second lifetime or the retransmission count of the MAC frame, which has failed in transmission exceeds an upper limit of the second lifetime or the retransmission count, the MAC frame which has failed in transmission is discarded.
