Patent ID: 8218689

Claim:
A wireless communication device comprising: a storage unit operable to store received data; a decoding unit operable to execute both of a first process that obtains a first decoding result by decoding new received data, which is not combined with stored received data, and a second process that obtains a second decoding result by decoding data generated by combining the same new received data and the stored received data, wherein the second process is performed in parallel with the first process; and a receiving device operable to receive a signal providing notification of either a new transmission or a retransmission; wherein the decoding unit is controlled such that, when the transmission is determined to be new transmission based on the notification, it is operable to execute decoding to obtain the second decoding result if an error is detected in the first decoding result, and to not execute decoding to obtain the second decoding result when no error is detected in the first decoding result.
