Abstract

"MéTODO, EQUIPAMENTO E SISTEMA PARA TRANSMISSãO DE DADOS E PROCESSAMENTO EM UM AMBIENTE DE COMUNICAçãO SEM FIO". De acordo com um aspecto da presente invenção, um método é fornecido no qual indicações de qualidade de sinal associada com cada uma dentre uma pluralidade de estações de usuário são recebidas. Múltiplas estações de usuário (por exemplo, uma primeira estação de usuário e uma segunda estação de usuário) são selecionadas para receber dados de uma estação base com base nas indicações da qualidade de sinal associada com a pluralidade de estações de usuário. Um primeiro pacote é construído, o qual contém dados de sinalização para a primeira estação de usuário e dados de aplicativo para a segunda estação de usuário. Um segundo pacote que contém dados de aplicativo para a primeira estação de usuário é superposto no primeiro pacote. Os primeiro e segundo pacotes são transmitidos simultaneamente a partir da estação base para as primeira e segunda estações de usuário.
