Abstract

"SISTEMA MIMO COM MODOS MúLTTPLOS DE MULTIPLEXAçãO ESPACIAL". Um sistema MIMO apóia múltiplos modos de multiplexação espacial para performance aperfeiçoada e maior flexibilidade. Estes modos podem incluir (1) um modo de comando de usuário simples que transmite fluxos de dados múltiplos em canais espaciais ortogonais até um receptor simples, (2) um modo não-comandado de usuário simples que transmite fluxos de dados múltiplos de antenas múltiplas para um receptor simples sem processamento espacial no transmissor, (3) um modo comandado de multi-usuário que transmite fluxos de dados múltiplos simultaneamente a receptores múltiplos com processamento espacial em uma transmissor, e (4) um modo não-comandado de multi-usuário que transmite fluxos de dados múltiplos de antenas múltiplas (co-localizados e não co-localizadas), sem processamento espacial nos transmissores para receptores, tendo antenas múltiplas. Para cada conjunto de terminais de usuário selecionados para transmissão de dados no link direto e/ou no link reverso, um modo de multiplexação espacial é escolhido para o conjunto de terminal de usuário entre os modos de multiplexação espacial suportados pelo sistema.
