Abstract

"MéTODO E EQUIPAMENTO PARA CONTROLE DE POTêNCIA DE MúLTIPLOS CANAIS EM UM SISTEMA DE COMUNICAçãO SEM FIO". Técnicas para o controle da potência de transmissão de múltiplas transmissões em sistema de comunicação sem fio. Uma fonte transmissora (por exemplo, uma estação base) recebe de um dispositivo receptor (por exemplo, terminal remoto) um número de retornos de uma ou mais fluxos de dados (codificados ou não codificados) e possivelmente uma ou mais mensagens. O fluxo de bit pode incluir um ou mais subcanais de controle de potência utilizados para enviar uma ou mais medidas (por exemplo, comandos de controle de potência, bits indicadores de eliminação, ou bits indicadores de qualidade) para um ou mais conjuntos de canais. os bits alocados para cada subcanal podem ser agregados para formar um ou mais subfluxos de retorno de taxa mais baixa possuindo uma confiabilidade acrescida. A potência de transmissão de dois ou mais canais pode ser (1) ajustada de forma independente com base nos retornos dos respectivos subcanais, ou (2) ajustadas juntas com base no retorno de um subcanal, com a diferença de potência sendo adjacente com base no retorno do outro subcanal.
