Abstract

métodos, aparelhos, e meios legíveis por computador para sinalização de alocação de recursos em uma rede de área local sem fio (wlan) de alta eficiência são divulgados. um transmissor pode identificar um primeiro indicador que identifica um número estações de múltipla entrada e múltipla saída de multiusuários (mu-mimo) associados com uma primeira unidade de recurso (ru) em um primeiro canal de conteúdo de um quadro de transmissão. o transmissor pode gerar uma primeira porção comum de um campo de sinalização de wlan no primeiro canal de conteúdo. a primeira porção comum pode incluir o primeiro indicador. o transmissor pode identificar um segundo indicador que identifica uma ausência de estações de mu-mimo associadas com uma segunda ru em um segundo canal de conteúdo do quadro de transmissão. o transmissor pode gerar uma segunda porção comum de campo de sinalização de wlan no segundo canal de conteúdo. a segunda porção comum pode incluir o segundo indicador. o transmissor pode transmitir o quadro de transmissão incluindo o campo de sinalização de wlan.
