Abstract

"MéTODO E EQUIPAMENTO PARA DETERMINAçãO DA NECESSIDADE DE TRANSMISSãO DE UM CANAL PILOTO PRIMáRIO E DE UM CANAL PILOTO SECUNDáRIO E APERFEIçOAMENTO DE ESTIMATIVA DE CANAL". Um método e um equipamento proporcionam processos de controle de taxa de dados e de controle de potência eficientes pela transmissão de um canal piloto primário e de um canal piloto secundário associados a um canal de dados. Os canais piloto primário e secundário são utilizados para aperfeiçoar a Relação Sinal/Ruído - SNR, as estimativas de fase e amplitude de referência pela combinação dos mesmos para a decodificação dos dados no canal de dados. A relação de níveis de potência dos canais piloto primário e secundário é baseada em pelo menos um da taxa de dados e do tamanho de carga útil do canal de dados. O nível de potência do canal piloto primário é mantido independente de pelo menos um da taxa de dados e do tamanho de carga útil do canal de dados. O nível de potência do canal piloto secundário pode ser ajustado com base em pelo menos um da taxa de dados e do tamanho de carga útil do canal de dados. Com base na comparação entre a taxa de dados calculada do canal de dados e um valor predeterminado, uma determinação é feita, se a transmissão do canal piloto comum primário e do canal piloto comum secundário é necessária.
