Abstract
A data structure of a MAC header for a WirelessHD communication system including an application layer, a media access controller (MAC) layer, and a physical (PHY) layer, includes, a payload data packet from the application layer; a MAC header of a fixed length; a MAC header extension of a variable length; a MAC header extension control field which signals if a particular field needs to be included or excluded; 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 checking transmission of the MAC header extension. Either the MAC header or the MAC header extension includes a size indication of the MAC header extension for facilitating checking of the second CRC segment.
