Abstract

resumo da patente de invenção para: “sinalização em duas fases para a transmissão de um fluxo de dados”. é proposto um conceito de sinalização em duas fases para um fluxo de dados que será transmitido de um transmissor para um receptor. no lado do transmissor, são criados vários cabeçalhos de frame (plh), cada cabeçalho de frame compreendendo parâmetros de transmissão de dados 1238a, 1238b para dados de carga útil 1236a, 1236b. é criado um cabeçalho super-frame sfh para um super-frame. o super-frame compreende vários frames, cada frame englobando um dos cabeçalhos do frame plh e dados de carga útil 1236a, 1236b. o cabeçalho super-frame indica um conjunto de parâmetros de transmissão do frame de super-frame constante 1218 para os cabeçalhos do frame dos vários frames do super-frame. um receptor avalia o cabeçalho super-frame sfh para obter os parâmetros de transmissão do cabeçalho do frame de super-frame constante 1218, que são depois usados para avaliar os vários cabeçalhos do frame plh para recuperar os parâmetros de transmissão dos dados 1238a, 1238b. o conceito proposto fornece uma flexibilidade acrescida, menos encargo de sinalização e/ou uma opção de um melhor desempenho do receptor a baixos níveis de snr. figura 6
