Frame generation apparatus and method of protecting protocol header information over wideband high frequency wireless system

A frame generation apparatus, comprising:

• a variable header generation unit to generate a variable length protocol header by receiving protocol header information;
• and
• a fixed header conversion unit to convert the variable length protocol header into a fixed length protocol header having a predetermined fixed length by adding a padding bits, having a value of ‘0’, to the variable length protocol header, and to insert the converted protocol header in a frame.

A frame generation method, comprising:

• generating a basic header of a frame including a PHY header, an MAC header, and a first HCS;
• and
• generating a selection header of the frame including a fixed length MAC subheader and a second HCS.
