Patent ID: 8312350

Claim:
A Mobile communication apparatus assigning a data to a radio frame to transmit the data to a receiving side apparatus, and assigning again the data to a radio frame corresponding to a reception timing of a failure response from the receiving side apparatus to retransmit the data to the receiving side apparatus, the failure response indicating the data has not been received normally by the receiving side apparatus, the mobile communication apparatus comprising: a setting unit setting a portion of the plurality of radio frames to be a dedicated retransmission frame according to a data reception quality level at the receiving side apparatus; and a retransmission controller assigning again the data to a radio frame corresponding to the reception timing of the failure response to retransmit the data to the receiving side apparatus, and further assigning the data to the dedicated retransmission frame to retransmit the data to the receiving side apparatus on receipt of the failure response, a transmission rate adjustment unit assigning a new data to only a radio frame other than the dedicated retransmission frame, wherein, by setting the dedicated retransmission frame, the number of capable retransmissions of the data is made to increase more than the maximum number of retransmissions before the dedicated retransmission frame is set.
