Title (EN) APPARATUS AND METHOD FOR TRANSMITTING AND RECEIVING A REVERSE CHANNEL IN A MOBILE COMMUNICATION SYSTEM FOR PACKET DATA
(FR) APPAREIL ET PROCEDE POUR LA TRANSMISSION ET LA RECEPTION D'UNE VOIE RETOUR DANS UN SYSTEME DE COMMUNICATION MOBILE POUR DES DONNEES DE PAQUET
Abstract:
(EN) An apparatus and method for transmitting and receiving a symbol through a reverse control channel in a mobile communication system for providing packet data are provided. When reverse traffic is present, the apparatus and method can effectively demodulate and decode the reverse traffic. In a method for transmitting a reverse channel in the mobile communication system capable of discontinuously transmitting packet data, a transmission is performed by setting power of a Data Rate Indicator (DRI) channel to a predefined power when packet data is transmitted. When no packet data is transmitted, a transmission is performed by decreasing the power of the DRI channel.
(FR) La présente invention a trait à un appareil et un procédé pour la transmission et la réception d'un symbole via une voie de commande retour dans un système de communication mobile pour la fourniture de données de paquet. Lorsque le trafic retour est présent, l'appareil et le procédé peuvent assurer efficacement la démodulation et le décodage du trafic retour. Dans un procédé pour la transmission d'une voie retour dans le système de communication mobile capable de transmission discontinue de données de paquet, une transmission est effectuée par le réglage de puissance d'un canal d'indicateur de débit de données à une puissance prédéterminée lors de la transmission de données de paquet. En l'absence de transmission de données de paquet, une transmission est effectuée par la réduction de la puissance de le canal d'indicateur de débit de données.
