    摘要： Provided are a frame generation apparatus and method that may protect variable length header information in a wideband high frequency wireless system. The frame generation apparatus may report variable length header information of a frame, and thereby the variable length header information may be verified in a receiving device. Also, the frame generation apparatus may convert a variable length header into a fixed length header by adding padding information to the variable length header of a frame, thereby protecting variable length header information.
