Abstract

a presente divulgação provê vários aspectos relacionados com técnicas para gerar quadros acionadores, em um ponto de acesso (ap), que reduzem o overhead associado a acionar uma transmissão de uplink a partir da estação sem fio (sta). características da presente divulgação alcançam isto ao, por exemplo, utilizar um campo de informação por usuário único do acionador para sinalizar uma pluralidade de unidades de recursos de acesso aleatório que podem ser atribuídas a uma ou mais stas em rede. tal técnica é um aperfeiçoamento em relação ao sistema convencional que exige que cada unidade de recursos de acesso aleatório seja sinalizada separadamente em um campo de informação por usuário separadamente (aumentando assim o overhead). além disso, aspectos da presente divulgação permitem que o ap efetivamente sinalize para a sta se os um ou mais recursos alocados a pelo menos uma sta são alocação de unidade de recursos de usuário único ou alocação de unidade de recursos de usuário de multiusuário.
