Abstract: front page image
(EN)A method for reporting and estimating power headroom, a terminal and a base station are provided. The Method for reporting power headroom includes: one carrier from multi-composition carriers is determined as a reporting carrier (S11); the transmission power headroom of the reporting carrier is reported to the base station, and the base station is notified to estimate the transmission power headroom of un-reporting carrier based on the transmission power headroom of the reporting carrier so as to obtain the transmission power headroom of the un-reporting carrier (S12); the un-reporting carrier is at least one carrier of the multi-composition carriers except the reporting carrier. The method reduces the signaling cost caused by reporting transmission power headroom without the terminal reporting the transmission power headroom of all the composition carriers.
(FR)La présente invention se rapporte à un procédé permettant de rapporter et d'estimer une marge de puissance, à un terminal et à une station de base. Le procédé permettant de rapporter une marge de puissance comprend les étapes suivantes : une porteuse parmi les porteuses à compositions multiples est déterminée comme étant une porteuse de rapport (S11); la marge de puissance de transmission de la porteuse de rapport est signalée à la station de base et la station de base reçoit une notification lui demandant d'estimer la marge de puissance de transmission d'une porteuse de non-rapport sur la base de la marge de puissance de transmission de la porteuse de rapport de sorte à obtenir la marge de puissance de transmission de la porteuse de non-rapport (S12); la porteuse de non-rapport est au moins une porteuse parmi les porteuses à compositions multiples à l'exception de la porteuse de rapport. Le procédé réduit le coût de signalisation provoqué par le rapport de la marge de puissance de transmission sans que le terminal rapporte la marge de puissance de transmission de toutes les porteuses de composition.
