Abstract
"INFORMAçãO DE MAPEAMENTO EM SISTEMAS DE COMUNICAçãO SEM FIO". Um sistema de comunicação sem fio inclui um canal de dados TDM compartilhado para comunicação em intervalos de tempo diferentes com respectivas estações móveis (MSs) bem como canais dedicados. Uma primeira subcamada de multiplexação de controle de acesso de meio (MAC), fornecida em uma controladora de estação base, mapeia a informação de canais lógicos para serviços de comunicação aos canais de comunicação. Uma segunda subcamada de multiplexação MAC mapeia a informação, mapeada para o canal de dados compartilhados na primeira subcamada de multiplexação MAC, às unidades de dados respectivas para comunicação nos respectivos intervalos de tempo TDM do canal compartilhado. A segunda subcamada de multiplexação MAC manuseia o escalonamento, a modulação adaptativa e a codificação, e a retransmissão automática da informação no canal de dados compartilhado, bem como canais de controle compartilhados para o canal de dados compartilhado e retroalimentação de qualidade de canal e canais de confirmação de dados das MSs.
