Abstract

"SISTEMA E MéTODO DE CONTROLE DE POTêNCIA DE TRANSMISSãO PARA POUPAR BATERIAS DA ESTAçãO MóVEL SEM REDUZIR CAPACIDADE DE CONEXãO". Um sistema de controle de potência de transmissão compreende um detector de deterioração de qualidade e uma unidade de ajuste de bit conectado a o detector de deterioração de qualidade. O detector de deterioração de qualidade detecta deterioração de qualidade de um estado de comunicação de comunicaçao por rádio entre uma estação base e estações móveis. A unidade de ajuste de bit de controle de potência de transmissão ajusta os sinais de bit de controle de potência de transmissão de modo a suprimir aumento de potência de transmissão das estações móveis quando o detector de deterioração de qualidade detectar uma deterioração de qualidade.
