1. A wireless LAN communication device comprising circuitry configured to:
generate a data frame comprising a first data unit in which an encoding process is performed on first data and a second data unit in which a retransmission process of the first data is performed, wherein the first data unit and the second data unit are separate from each other, the encoding process making it possible to determine whether or not the first data of the first data unit is successfully decoded;
append, to the data frame, information for use in identification of data to be subjected to the retransmission process; and
transmit the data frame,
wherein the information for use in identification of the data to be subjected to the retransmission process includes data length information and sequence number information of the data,
wherein
a range in data for which a reception process has been unsuccessful is specified;
a combining process with a portion of retransmitted data is, and
the combining process is performed by combining a portion of the first data of the first data unit that was decoded successfully with a portion of the first data from the second data unit, the portion of the first data from the second data unit corresponding to the portion of the first data of the first data unit that was not decoded successfully.
