摘要
Various embodiments disclosed herein provide for a closed loop Listen Before Talk (LBT) which is a coexistence mechanism used by wireless technologies such as Wi-Fi, to access unlicensed shared spectrum, such as the ISM UNII bands (5 GHz). The embodiments disclosed herein enable a base station to coordinate the LBT process at both the base station and a receiver in order to avoid hidden node interference where the interfering nodes are outside the sensing range of the transmitting node. The base station device can send a LBT trigger to the receiver to synchronize the clear channel assessments that are performed at each device to determine if there is any activity on the channel. The receiving device can send back a report to the base station device, and if no activity on the channel is detected, the base station device can schedule a transmission on the channel.
