Abstract
"DETERMINAçãO DE FATORES DE GANHO PARA POTêNCIA DE COMUNICAçãO SEM FIO". São fornecidos aparelho e métodos de controle da potência de transmissão de comunicações sem fio. A determinação de fatores de ganho e ajustes da reconfiguração de canais físicos no contexto do controle de potência de transmissão é abordada. Preferencialmente, a implementação ocorre em conjunto com sistemas de comunicação nos quais as comunicações sem fio são conduzidas entre unidades de transmissão e recepção sem fio (WTRUs) utilizando diversos canais que são transmitidos simultaneamente.
