Abstract
A method, a device, and a non-transitory computer-readable storage medium are described in which a Listen Before Talk-based dynamic energy detection service is provided. The dynamic energy detection service includes provisioning a dynamic threshold value that is used during a clear channel assessment procedure. The dynamic threshold value may be increased or decreased by an adjustment value depending on the success or failure of a data transmission indicated by an end device.
Claims20
A method comprising:
- measuring, by a network device, a power value on a downlink channel that uses unlicensed radio spectrum;
- comparing, by the network device, the measured power value to a threshold power value;
- transmitting, by the network device when the measured power value satisfies the threshold power value, data to an end device via the downlink channel, wherein the end device is attached to the network device;
- determining, by the network device, a success or a failure of receipt of the data by the end device based on a message received from the end device;
- and
- increasing or decreasing, by the network device, the threshold power value based on the success or the failure.
A network device of a wireless access network comprising:
- a communication interface;
- and
- a processor, wherein the processor is configured to:
- measure a power value on a downlink channel that uses unlicensed radio spectrum;
- compare the measured power value to a threshold power value;
- transmit, via the communication interface when the measured power value satisfies the threshold power value, data to an end device via the downlink channel, wherein the end device is attached to the network device;
- determine a success or a failure of receipt of the data by the end device based on a message received from the end device;
- and
- increase or decrease the threshold power value based on the success or the failure.
A non-transitory computer-readable storage medium storing instructions executable by a processor of a device, which when executed cause the device to:
- measure a power value on a downlink channel that uses unlicensed radio spectrum;
- compare the measured power value to a threshold power value;
- transmit data to an end device via the downlink channel when the measured power value satisfies the threshold power value, wherein the end device is attached to the device;
- determine a success or a failure of receipt of the data by the end device based on a message received from the end device;
- and
- increase or decrease the threshold power value based on the success or the failure.
