Patent ID: 7076718

Claim:
A reception apparatus comprising: a demodulation section that demodulates a received packet; a channel quality estimation section that estimates radio channel quality of the demodulated received packet; a combining determination section that determines whether or not to combine the received packet based on the radio channel quality; a combining section that combines the received packet selected in the combining determination section to generate a first combined packet; an error correcting decoding section that performs error correcting decoding on the first combined packet; and an error detecting section which performs error detection on an output signal from the error correcting decoding section, and when an error is detected, transmits a retransmission request command to a communicating party, wherein the channel quality estimation section calculates likelihood of a second combined packet obtained by combining the first combined packet that is combined earlier and a received packet, and the combining determination section selects only a received packet such that the likelihood of the second combined packet is more than the likelihood of the first combined packet.
