Abstract
(EN)
A method for obtaining transmitting power, a method and system for measuring channel quality and interference intensity are disclosed in the present invention, wherein the method for measuring channel quality is used to measure the channel quality information in wireless communication system and includes the following step: base station transmits a reference signal in the frequency partition through the downlink channel to enable a terminal to use the reference signal to measure the channel quality information of the frequency partition. By the present invention, the base station can transmit the reference signal in every frequency partition through the downlink channel according to the transmitting power of the every frequency partition to enable the terminal to use the reference signal to measure the channel quality information of every frequency partition, and so the accuracy of the measured channel quality information in the terminal can be improved.

L'invention porte sur un procédé d'obtention de puissance d'émission, sur un procédé et un système de mesure d'une qualité de canal et d'une intensité d'interférence. On utilise le procédé de mesure de qualité de canal pour mesurer des informations de qualité de canal dans un système de communication sans fil, le procédé comprenant l'étape suivante : une station de base transmet un signal de référence dans la partition de fréquence par le canal de liaison descendante afin de permettre à un terminal d'utiliser le signal de référence pour mesurer les informations de qualité de canal de la partition de fréquence. Au moyen de la présente invention, la station de base peut émettre le signal de référence dans chaque partition de fréquence par le canal de liaison descendante conformément à la puissance d'émission de chaque partition de fréquence afin de permettre au terminal d'utiliser le signal de référence pour mesurer les informations de qualité de canal de chaque partition de fréquence, et on peut améliorer ainsi la précision des informations de qualité de canal mesurée dans le terminal.
