An apparatus and method for transmitting and receiving forward channel quality information between a base station and a mobile station in a CDMA mobile communication system supporting multimedia service including voice and data services. The mobile station transmits an absolute value symbol in at least one time slot selected from a plurality of time slots, and a relative value symbol in one of the remaining time slots. The absolute value symbol represents the signal strength of the forward channel in the at least one time slot corresponding to the selected time slot, and the relative value symbol represents a change in the signal strength of the forward channel between the at least one time slot corresponding to the one remaining time slot and the signal strength of the forward channel in a previous time slot.
L'invention concerne un appareil et un procédé d'émission et de réception d'informations de qualité d'un canal aller entre une station de base et une station mobile dans un système de communication mobile CDMA prenant en charge un service multimédia comprenant des services vocaux et des services de données. La station mobile émet un symbole de valeur absolue dans au moins un créneau temporel sélectionné parmi une pluralité de créneaux temporels, et un symbole de valeur relative dans l'un des créneaux temporels restants. Le symbole de valeur absolue représente la force de signal d'un canal aller dans au moins un créneau temporel correspondant au créneau temporel sélectionné, et le symbole de valeur relative représente une modification de la force du signal du canal aller entre le créneau temporel correspondant au créneau temporal restant, et la force du signal du canal aller d'un créneau temporel précédent.
