摘要： A communication apparatus includes a receiving device configured to receive a physical frame in which a plurality of MAC frames, each having a sequence number, are aggregated. A reception buffer which stores MAC frames of the physical frame received by the receiving device. A determination device determines whether or not the first MAC frame in the physical frame received by the receiving device has been successfully received. A reception buffer management device determines, when the first MAC frame has been successfully received, a MAC frame to be forwarded to an upper layer, on the basis of the sequence number of the first MAC frame, and extracts the MAC frame from the reception buffer.

摘要： A wireless communication apparatus is disclosed. A transmitting device transmits a first aggregation frame in which first transmission data frames are aggregated. A measuring device measures a number value of retransmission of each of the first transmission data frames. A storage stores a limiting value of the number value of retransmission. A determination device determines whether the number value of retransmission of each of the first transmission data frames exceeds the limiting value. A transmission buffer buffers the first transmission data frames for which it is determined that the number value of retransmission does not exceed the limiting value, and discards the first transmission data frames for which it is determined that the number value of retransmission exceeds the limiting value, of the first transmission data frames. A retransmitting device retransmits the first aggregation frame in which the first transmission data frames buffered in the transmission buffer are aggregated.
