Patent ID: 11882479
Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATION
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A wireless LAN (Local Area Network) communication device configured to:
generate an MPDU (MAC Protocol Data Unit) by attaching a MAC header to transmission data, generate an A-MPDU (Aggregate MAC Protocol Data Unit) sub frame by attaching an MPDU delimiter to the MPDU, generate an A-MPDU by aggregating a plurality of A-MPDU subframes, and transmit the A-MPDU, the wireless LAN communication device comprising:
an MPDU redundancy unit, including one or more processors, configured to determine whether or not the transmission data is a redundancy target according to a required quality of the transmission data, determine that the MPDU generated from the transmission data determined to be a redundancy target is a redundant MPDU, and generate a duplicate MPDU by duplicating the redundant MPDU; and
an A-MPDU generation unit, including one or more processors, configured to generate the A-MPDU that includes the redundant MPDU and the duplicate MPDU.
