Abstract

"MéTODO E EQUIPAMENTO PARA REPORTAR REALIMENTAçãO EM UM SISTEMA DE COMUNICAçãO SEM FIO". A presente invenção refere-se à realimentação das estações de usuário para a estação base para uma transmissão de multicast/broadcast é realizada pela decodificação dos dados de multicast/broadcast recebidos de um transmissor em um recurso de downlink, formação de uma mensagem de realimentação correspondente à recepção de O dados de multicast/broadcast e enfileiramento da mensagem de realimentação para transmissão para o transmissor em um recurso de uplink. O recurso de uplink utilizado corresponde ao recurso de downlink utilizado para a transmissão de multicast/broadcast. Para as transmissões de unicast o recurso de uplink é dedicado a uma transmissão de uplink correspondente a uma transmissão de downlink no recurso de downlink.
