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.

L'invention concerne un procédé de transmission de données d'attribution de rafales par une station de base dans un système de transmission sans fil à large bande, dans lequel une trame transmise comprend des symboles, et les sous-porteuses orthogonales d'un axe de fréquence forment chacun des symboles selon une unité de temps prédéterminée. Le procédé comporte les étapes consistant à : produire un identificateur de connexion (CID) réduit en réduisant le CID de base d'un terminal mobile connecté à la station de base lorsque le CID de base se situe dans une plage prédéfinie ; insérer dans la trame une MAP, qui comprend un champ activé représentant le CID réduit et indiquant l'utilisation ou la non-utilisation du CID réduit ; et transmettre la trame au terminal mobile.
