Abstract
(EN)
The embodiment of the invention relates to a transmission method, base station and user equipment for channel quality information. The transmission method for channel quality information comprises: when a user equipment needs to feedback channel quality information corresponding to Y-number of downlink carriers through X-number of uplink carriers to the base station, the base station allocates resource blocks for the user equipment according to a set of channel quality information bit and X/Y ratio corresponding to a resource block count, wherein X and Y are positive integers greater than or equal to 1 (11); the base station configures the allocated resource block count into a uplink scheduling control signal UL-grant, and sends the signal to the user equipment(12). Thus, the base station is able to allocate resource blocks for user equipment according to the channel quality information bits and resource block count set, thereby adaptively allocating the uplink scheduling bandwidth, avoiding the problem of user equipment only being able to transmit channel quality information under fixed bandwidth resource and the defect of being unable to satisfy transmission performance.

L'invention concerne, selon un mode de réalisation, un procédé de transmission, une station de base et un équipement utilisateur pour la transmission d'informations de qualité de canal. Le procédé de transmission d'informations de qualité de canal est mis en oeuvre comme suit: lorsqu'un équipement utilisateur veut envoyer à la station de base des rétro-informations de qualité de canal correspondant à un nombre Y de porteuses de liaison descendante, par le biais d'un nombre X de porteuses de liaison montante, la station de base attribue des blocs de ressources à l'équipement utilisateur selon un ensemble de bits d'information de qualité de canal et un rapport X/Y correspondant à un nombre de blocs de ressources, X et Y étant des entiers positifs supérieurs ou égaux à 1 (11); la station de base configure le nombre de blocs de ressources attribués et le transforme en autorisation UL de signal de commande de programmation de liaison montante, et envoie le signal à l'équipement utilisateur (12). Ainsi, la station de base peut attribuer des blocs de ressources à l'équipement utilisateur en fonction des bits d'information de qualité de canal et de l'ensemble de nombre de blocs de ressources, ce qui permet d'attribuer de manière adaptative la largeur de bande de programmation de liaison montante, et d'éviter le problème imposant à l'équipement utilisateur de ne transmettre des informations de qualité de canal qu'avec des ressources de bande passante fixe, ainsi que la lacune découlant de l'incapacité d'accomplir une transmission performante.
