Abstract
Various embodiments are provided to address some of the current issues in establishing and adapting an HARQ operating point. Some embodiments include determining a metric that indicates the predictability of a signal to noise plus interference ratio (SINR) for signaling from a wireless device and setting a hybrid automatic repeat request (HARQ) operating point for communication with the wireless device using the metric. By setting the HARQ operating point based on a metric that indicates the predictability of SINR for wireless device signaling, throughput can be improved over present-day HARQ operating point adaptation techniques.

A method, comprising:
- determining a metric that indicates a predictability of a signal to noise plus interference ratio (SINR) for signaling from a wireless device;
- setting a hybrid automatic repeat request (HARQ) operating point for communication with the wireless device using the metric, wherein the method further comprises:
- receiving a first signal from the wireless device;
- predicting, using the received first signal, an estimated SINR for a second signal to be transmitted by the wireless device;
- determining an actual SINR for the second signal when the second signal is received from the wireless device.
A transceiver node of a communication system, the transceiver node being configured to communicate with other devices in the communication system, wherein the transceiver node is operative
- to determine a metric that indicates a predictability of a signal to noise plus interference ratio (SINR) for signaling from a wireless device, and
- to set a hybrid automatic repeat request (HARQ) operating point for communication with the wireless device using the metric, wherein the transceiver node is further operative
- to receive a first signal from the wireless device,
- to predict, using the received first signal, an estimated SINR for a second signal to be transmitted by the wireless device, and
- to determine an actual SINR for the second signal when the second signal is received from the wireless device.
