Patent ID: 8077637

Claim:
A mobile communication apparatus receiving and storing data transmitted from an apparatus on a transmitting side over a period of a plurality of processing time units, and at a time of retransmitting the data, having a retransmission control function of performing composition processing of the stored data with the data being retransmitted over the period of a plurality of processing time units, on a basis of each processing time unit, the mobile communication apparatus comprising: a reception decision circuitry section executing reception decision processing for deciding presence or non-presence of reception error in the entire data transmitted over a plurality of processing time units on which composition processing is performed, based on each processing time unit, wherein, before the completion of the reception of the entire data retransmitted over the plurality of processing time units on which composition processing is performed, the reception decision circuit section decides a normal decision indicative of no reception error; and a transmission circuitry section notifying the apparatus on the transmitting side of the reception decision result based on each processing time unit.
