Abstract

ESTRUTURAS DE CANAL PARA UM SISTEMA DE COMUNICAçãO DE ACESSO MúLTIPLO QUASE ORTOGONAL. Uma estrutura de canal possui pelo menos dois conjuntos de canal. Cada conjunto de canal contém múltiplos canais e está associado com um mapeamento específico dos canais para os recursos de sistema disponíveis para a transmissão de dados. Cada conjunto de canal pode ser definido com base em uma árvore de canal possuindo uma estrutura hierárquica. Para se alcançar a diversidade de interferência intracelular, o mapeamento de canal para recurso para cada conjunto de canal é pseudo-aleatório com relação ao mapeamento para cada conjunto de canal restante. Em cada intervalo de programação, os terminais são programados para transmissão no link direto e/ou reverso. Os terminais programados recebem canais dos conjuntos de canal. Múltiplos terminais podem utilizar os mesmos recursos de sistema e suas transmissões sobrepostas podem ser separadas no domínio espacial. Por exemplo, a formação de feixe pode ser realizada para enviar múltiplas transmissões sobrepostas no link direto, e o processamento espacial do receptor pode ser realizado para separar múltiplas transmissões sobrepostas recebidas no link reverso.
