Abstract
A wireless LAN communication device generates an MPDU by attaching a MAC header to transmission data, generates an A-MPDU subframe by attaching an MPDU delimiter to the MPDU, generates an A-MPDU by aggregating a plurality of A-MPDU subframes, and transmits the A-MPDU. The wireless LAN communication device includes: an MPDU duplicating means for determining whether or not transmission data is a redundancy target according to a required quality of the transmission data, determining that an MPDU generated from the transmission data determined to be a redundancy target is a redundant MPDU, and generating a duplicate MPDU by duplicating the redundant MPDU; and an A-MPDU generating means for generating an A-MPDU that includes the redundant MPDU and the duplicate MPDU.
