A method for transmitting uplink control information in a communication system using an orthogonal frequency division multiple access (OFDMA) scheme is provided. A mobile station (MS) selects a target anchor base station (BS) with which the MS desires to communicate through a fast feedback channel, and transmits a codeword allocated to the selected target anchor BS to a current anchor BS. Upon receiving the codeword, transmitting to the MS, by the anchor BS, fast feedback channel allocation information for the selected BS corresponding to the received codeword. The MS switches to a new anchor BS corresponding to the fast feedback channel allocation information.

Procédé de transmission d'une information de commande en liaison montante dans un système de communication utilisant un accès par multiplexage par répartition orthogonale de la fréquence (OFDMA). Ce procédé englobe les opérations suivantes: sélection par une station mobile (MS) d'une station de base pivot cible (BS) avec laquelle elle souhaite communiquer par un canal à retour rapide; transmission d'un mot de code attribué à la station de base pivot cible à une station de base pivot actuelle; à la réception du mot de passe, transmission à la station mobile MS, par la station de base pivot BS, d'informations d'attribution d'un canal à rétroaction rapide pour la station de base BS sélectionnée correspondant au mot de passe reçu. La station mobile bascule sur une nouvelle station de base pivot BS correspondant aux informations d'attribution d'un canal à rétroaction rapide.
