Patent ID: 8102853

Claim:
A non-transitory computer readable medium storing a data structure of a MAC header for a High Definition communication system, using a open systems interconnection (OSI) reference model including an application layer, a media access controller (MAC) layer, and a physical (PHY) layer, comprising: a payload data packet received from the application layer; a fixed length MAC header for controlling a plurality of first type of functions of the MAC layer; a MAC header extension of a variable length for controlling a plurality of second type of functions of the MAC layer, wherein the MAC header extension is isolated from the MAC header; a PHY header for synchronizing the behavior of the PHY layer; a first CRC segment for a cyclic redundancy checksum for checking transmission of the MAC header and the PHY header; and a second CRC segment for a cyclic redundancy checksum for separately checking the transmission of the MAC header extension, wherein the MAC header comprises a size indication of the MAC header extension, the size indication referred in facilitating checking of the second CRC segment, wherein the MAC header extension further comprises a ReBoM header, a Link adaptation extension header, and a composite frame header, and wherein presence or absence of the ReBoM header, the Link adaptation extension header, and the composite frame header are determined by values of the corresponding MAC header extension control bits.
