Abstract
A method for transmitting burst allocation information by a base station in a broadband wireless communication system in which a transmitted frame includes symbols, and orthogonal subcarriers in a frequency axis constitute each of the symbols based on a predetermined time unit. The method includes the steps of generating a reduced connection identifier (CID) by reducing a basic CID of a mobile terminal connected to the base station when the basic CID exists within a preset range, and inserting an MAP, which includes an enabled field representing the reduced CID and one of use and non-use of the reduced CID, into the frame, and transmitting the frame to the mobile terminal.
