Abstract

técnicas de realimentação de confirmação em espectro de radiofrequência compartilhado. são descritos métodos, sistemas e dispositivos para comunicações sem fio que fornecem relatórios de realimentação de confirmação (ack) em grupo ou de ação única, no qual a realimentação para um número de transmissões de downlink diferentes pode ser fornecida por um equipamento de usuário (ue) para uma estação base. uma estação base pode acionar um relatório de realimentação de ação única, que inclui menos do que toda a realimentação de ack que está disponível no ue, para se fornecer em um relatório. a realimentação de ack pode incluir uma indicação de uma ack ou uma confirmação negativa (nack) juntamente com informações relacionadas a um indicador de dados associado com a transmissão de downlink. em alguns casos, os relatórios de realimentação de ack regular e os relatórios de realimentação de ação única podem ser multiplexados e transmitidos por um ue. além disso, uma última transmissão de downlink a ser incluída em um relatório de realimentação de ação única pode ser determinada com base em um tempo de recepção de informações de programação ou na cronologia de realimentação de ack.
