Abstract
This disclosure provides methods, components, devices, and systems for prediction-based latency aware power saving using adaptive target wake time (TWT). Some aspects more specifically relate to aligning traffic flows from multiple applications by using next expected times for packet transmissions, latency threshold values, processing times, and statistics to determine a next TWT. The next TWT may be communicated from a wireless device to a companion device. The wireless device may enter a sleep mode until the next TWT.
Claims20
A wireless device, comprising:
- one or more memories storing processor-executable code;
- and
- one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the wireless device to:
- transmit an indication of a predicted wakeup time in accordance with a first transmit time associated with first data from a first application adjusted by a first latency value and a second transmit time associated with second data from a second application adjusted by a second latency value, wherein the predicted wakeup time aligns, in time, at least the first data with the second data;
- and
- transmit or receive at least the first data or the second data in accordance with the predicted wakeup time.
A wireless device, comprising:

- one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the wireless device to:
- receive an indication of a predicted wakeup time in accordance with a first transmit time associated with first data from a first application adjusted by a first latency value and a second transmit time associated with second data from a second application adjusted by a second latency value, wherein the predicted wakeup time aligns, in time, at least the first data with the second data;
- and
- transmit or receive at least the first data or the second data in accordance with the predicted wakeup time.
A method for wireless communications at a wireless device, comprising:
- transmitting an indication of a predicted wakeup time in accordance with a first transmit time associated with first data from a first application adjusted by a first latency value and a second transmit time associated with second data from a second application adjusted by a second latency value, wherein the predicted wakeup time aligns, in time, at least the first data with the second data;
- and
- transmitting or receiving at least the first data or the second data in accordance with the predicted wakeup time.
