Abstract

métodos, sistemas e dispositivos para comunicação sem fio são descritos. uma estação base pode se comunicar com múltiplos equipamentos de usuário (ues) em um sistema sem fio suportando a transmissão direcional em espectro compartilhado (por exemplo, em espectro de onda milimétrica (mmw)). a estação base pode competir pelo canal (por exemplo, utilizando um procedimento escuta antes de falar (lbt)) e, após o sucesso, transmitir um sinal de reserva de canal (cr) direcional para cada um dentre os múltiplos ues. o sinal cr pode reservar o canal por um período de tempo específico e indicar um tempo de início, um tempo de término, ou ambos. o ue pode responder com outra transmissão cr. em alguns exemplos, a estação base pode transmitir sinais cr para cada um dos ues em uma única transmissão por rajada. em outros exemplos, a estação base pode transmitir sinais cr para os ues sequencialmente de modo que se um ue não responder o tempo reservado pode ser alocado para outro ue.
