Abstract

um ponto de acesso de uma rede de comunicação sem fio ao qual é conectada uma pluralidade de terminais transmite tramas de acionamento de procedimento de acesso aleatório coordenado, oferecendo assim uma oportunidade de acesso ao meio da rede de comunicação sem fio a cada terminal ao qual essa trama é destinada. cada terminal que pega a oportunidade de acesso ao meio efetua uma transmissão ascendente de tipo ofdma em resposta à dita trama. o ponto de acesso inclui (303, 308) em cada trama de acionamento de procedimento de acesso aleatório coordenado informações representativas de um método de seleção de recurso frequencial dentre um método de seleção aleatória e um método de seleção livre.
