Abstract

"APARATO E MéTODO PARA CONTROLE DA POTêNCIA DE TRANSMISSãO EM UM SISTEMA DE COMUNICAçãO SEM FIO". A presente invenção provê um aparato e um método para controlar a potência de transmissão de um CIQCR (canal indicador de qualidade de canal reverso) e um CRECR (canal de reconhecimento reverso) independentemente. A presente invenção inclui as etapas de receber um primeiro parâmetro correspondendo ao CIQCR e um segundo parâmetro correspondendo ao CRECR de uma estação base via uma mensagem aérea e determinar independentemente as potências de transmissão do CIQCR e do CRECR usando o primeiro e segundo parâmetros.
