Abstract

''PROCESSO DE CONTROLAR O NìVEL DE POTêNCIA DE SINAIS TRANSMITIDOS POR ESTAçõES DE BASE EM UM SISTEMA DE COMUNICAçãO''. Processo de controlar os níveis de potência de sinais transmitidos em sistemas de telecomunicação são descritos. Por exemplo, um terminal remoto mede a qualidade de um sinal recebido, quer determinando a taxa de erros de quadro ou taxa de erros de bits, e reporta sua medição de qualidade a uma rede emitindo uma mensagem de qualidade. A rede causa os transmissores de sinal a ajustarem seus níveis de potência de transmissão apropriadamente. Processos de controle de potência mais rápidos podem ser combinados com processos de controle de potência mais lentos para transmissões de enlace descendente (rede para terminal remoto) em vários cenários de comunicações, tais como transferência suave.
