Abstract

MÉTODO E APARELHO PARA A CALIBRAÇÃO DE POTÊNCIA DE TRANSMISSÃO EM UM SISTEMA SEM FIO MULTIPLEXADO POR DIVISÃO FREQÜÊNCIA. A presente exposição descreve um método e um aparelho para a calibração de potência de transmissão em um sistema sem fio multiplexado de divisão de freqüência (100). o método pode incluir o recebimento (315) de uma concessão de programação de enlace ascendente em um equipamento de usuário (120), o estabelecimento (320) de um nível de potência desejado com base pelo menos na concessão de programação de enlace ascendente, e a regulagem (325) de regulagens de potência de hardware com base no nível de potência desejado. o método também pode incluir a transmissão (330) de dados em um primeiro subquadro em um primeiro nível de potência com base nas regulagens de potência de hardware, a medição (335) do primeiro nível de potência no primeiro subquadro e a determinação ( 34 O) de uma diferença entre o nível de potência desejado e o primeiro nível de potência medido. O método adicionalmente pode incluir a modificação (345) de regulagens de potência de hardware com base na diferença e a transmissão (350) em um segundo nível de potência com base nas regulagens de potência de hardware modificadas em uma próxima transmissão correspondente à transmissão no primeiro subquadro.
