Abstract:
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.

Claim (Index 13):
A method, comprising:\n facilitating, by a base station device comprising a processor, transmitting a request for a first clear channel assessment to a first user equipment device via a downlink control channel, the request comprising an instruction to the first user equipment device to perform the first clear channel assessment on a frequency band at a predetermined time, wherein the request is transmitted in a mini-slot within a duration of a slot of the downlink control channel in response to a listen before talk duration being less than a length of the slot; performing, by the base station device, a second clear channel assessment on the frequency band at the predetermined time; facilitating, by the base station device, receiving a first result of the first clear channel assessment from the first user equipment device via an uplink control channel; and in response to the first result of the first clear channel assessment and a second result of the second clear channel assessment indicating that the frequency band is clear, scheduling, by the base station device, a first transmission to the first user equipment device on the frequency band.
