Abstract: front page image
(EN)The present invention discloses a method for power headroom report calculation in carrier aggregation and a system thereof. The method includes the following steps: when Power Headroom Reports (PHRs) of multiple component carriers in carrier aggregation are reported, for the component carrier used for transmitting the PHRs of the multiple component carriers, power headroom (PH) value is calculated based on the sub-frame used for transmitting the PHRs; for the other component carriers, the PH value of each carrier is calculated based on an uplink transmission sub-frame, which is the closest to the sub-frame used for transmitting the PHRs, of the component carrier itself. By the implementation of the method and system of the present invention, a base station can estimate exactly, according to the received PHRs, the total transmission power of a user equipment (UE) in all the component carriers in the carrier aggregation.
(FR)L'invention concerne un procédé de calcul d'un rapport de marge de puissance dans une agrégation de porteuses et un système correspondant. Le procédé comprend les étapes consistant à : quand les rapports de marge de puissance (PH) de multiples porteuses composantes d'une agrégation de porteuses sont transmis, calculer une valeur de marge de puissance pour la porteuse composante servant à transmettre les PHR des multiples porteuses composantes sur la base de la sous-trame utilisée pour transmettre les PHR; pour les autres porteuses composantes, calculer la valeur de PH de chaque porteuse sur la base d'une sous-trame de transmission de liaison montante qui constitue la sous-trame de cette porteuse composante qui est la plus proche de celle utilisée pour transmettre les PHR. La mise en œuvre du procédé et du système de l'invention permet à une station de base d'estimer exactement, selon les PHR reçus, la puissance d'émission totale d'une installation d'abonné (UE) dans toutes les porteuses composantes de l'agrégation de porteuses.
