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

Claim 3:
4. A wireless LAN (Local Area Network) communication method for generating an MPDU (MAC Protocol Data Unit) by attaching a MAC header to transmission data, generating an A-MPDU (Aggregate MAC Protocol Data Unit) subframe by attaching an MPDU delimiter to the MPDU, generating an A-MPDU by aggregating a plurality of A-MPDU subframes, and transmitting the A-MPDU, the wireless LAN communication method comprising:
determining whether or not the transmission data is a redundancy target according to a required quality of the transmission data, determining that the 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
generating the A-MPDU that includes the redundant MPDU and the duplicate MPDU.
