APPARATUS AND METHOD DECREASING TRANSMIT OVER HEAD IN BROADBAND WIRELESS COMMUNICATION SYSTEM

摘要

An apparatus and a method for reducing a transmission-over-head in a broadband wireless communication system are provided to reduce the transmission-over-head by inserting allocation information of a data burst into a burst preamble in a wireless communication system based on OFDM(Orthogonal Frequency Division Multiplexing). An apparatus for reducing a transmission-over-head in a broadband wireless communication system includes a head generator(501), and a traffic channel forming unit(505). The head generator(501) generates a head including data allocation information and control information of each frame to be transmitted. The traffic channel forming unit(505) forms a traffic channel by combining the generated head with a burst. Each frame is allocated to one user for total frequency band. Transmission data is allocated on each frame according to a time resource. The data allocation information includes a user ID(Identification), a time domain start point of the burst, and a length of the burst to be allocated on the frame.
