Abstract
métodos, sistemas e aparelhos são descritos para comunicação sem fio em uma estação base. a estação base pode transmitir uma mensagem de controle para um conjunto de equipamentos de usuário (ues) utilizando uma transmissão direcional tendo uma primeira largura de conformação de feixe. a estação base pode trocar, de acordo com a mensagem de controle, mensagens de dados com um primeiro ue do conjunto de ues utilizando uma transmissão direcional tendo uma segunda largura de conformação de feixe. a segunda largura de conformação de feixe pode ser diferente da primeira largura de conformação de feixe. a estação base pode trocar, de acordo com a mensagem de controle, mensagens de dados com um segundo ue dentre o conjunto de ues utilizando uma transmissão direcional tendo uma terceira largura de conformação de feixe. a terceira largura de conformação de feixe pode ser diferente da primeira largura de conformação de feixe, da segunda largura de conformação de feixe, ou de ambas.
