Abstract
"MéTODO E EQUIPAMENTO PARA DETERMINAR POTêNCIA DE TRANSMISSãO DISPONìVEL EM UM SISTEMA DE COMUNICAçãO SEM FIO". Técnicas para estimar (de forma mais precisa) a potência de transmissão disponível para serviço de dados em um período de tempo futuro (por exemplo, o próximo frame). De acordo com um aspecto, a variação na potência de transmissão disponível através do tempo é estimada. Uma primeira margem é então computada e utilizada para responder pela variação estimada na potência de transmissão disponível. A potência de transmissão disponível em uma instância de tempo futuro (por exemplo, o começo do próximo frame) é prevista e reduzida pela primeira margem para derivar uma estimativa mais acurada da potência de transmissão disponível para o próximo frame. De acordo com outro aspecto, a variação na potência de transmissão requerida para um usuário de dados em particular é estimada e utilizada na programação da transmissão de dados para esse usuário de dados. Uma segunda margem pode ser computada e utilizada pare responder pela variação estimada na potência de transmissão requerida para o usuário de dados. Ao passo que a primeira margem responde pela variação na potência de transmissão disponível (total), a segunda margem é específica para as condições de link particulares experimentadas pelo usuário de dados.
