CA 2374972
A base station apparatus (100) notifies a mobile station apparatus (110-K) of information (power ratio information) indicative of the ratio of the transmission power of a common known signal (common PL) included in a common control channel to the transmission power of a signal included in a downlink shared channel. The mobile station apparatus (110-K) precisely positions a determination point on the basis of the foregoing power ratio information and accurately effects a QAM demodulation.
Selon l'invention, une station (100) de base notifie à une station mobile (100-K) des informations (informations de rapport de puissance) indiquant le rapport entre la puissance de transmission d'un signal connu commun (PL commun) inclus dans un canal de signalisation commun et la puissance de transmission d'un signal inclus dans un canal descendant partagé. La station mobile (110-K) effectue le positionnement précis d'un point de détermination sur la base des informations de rapport de puissance susmentionnées et procède, avec exactitude, à une démodulation QAM.
