Abstract
adaptação de taxa para sdma. parâmetro de transmissão (430) paar um link em uma rede sem fio (100) é adaptado para uma transmissão simultânea atual com base em um parâmetro de perda. o parâmetro de perda é utilizável para determinar uma alocação para um nó sem fio (120d) de uma pluralidade de nós sem fio (120d, 120e) participando na transmissão simultânea. em alguns exemplos, o parâmetro de transmissão selecionado (430) e os parâmetros de perda para uma transmissão anteriro, em conjunto com o parâmetro de perda para transmissão simultânea atual são utilizados para determinar o parâmetro de transmissão (410). em algumas modalidades, um ponto de acesso (ap) (110) determina e comunica um parâmetro de perda a uma pluralidade de terminais de acesso (at) (120d, 120e). cada at determina um esquema de modulação e codificação (mcs) com base ao menos em parte no parâmetro de perda. cada at transmite simultaneamenteao menos um fluxo de dados (160, 170) ao ap de acordo com o msc determinado. em algumas outras modalidades, a taxa de transmissão para comunicações simultâneas de downlink (140, 150) é similarmente adaptada.
