Abstract

PROPAGAÇÃO DE COMPARTILHAMENTO DE TEMPO DE OCUPAÇÃO DE CANAL (COT). A presente invenção refere-se a sistemas, métodos e aparelhos, incluindo programas de computador codificados em mídias de armazenamento de computador, para comunicação sem fio. Em um aspecto da divulgação, um método para comunicação sem fio por um equipamento de usuário (UE) inclui receber uma primeira mensagem a partir de um primeiro dispositivo. O primeiro dispositivo inclui um originador de um primeiro tempo de ocupação de canal (COT). O método também pode incluir transmitir uma segunda mensagem incluindo uma identidade de origem (ID) do primeiro dispositivo. Outros aspectos e recursos também são reivindicados e descritos.
