TECHNIQUES FOR BITRATE CONTROL IN WIRELESS COMMUNICATIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17947653 titled 'TECHNIQUES FOR BITRATE CONTROL IN WIRELESS COMMUNICATIONS

Simplified Explanation

The patent application describes methods, systems, and devices for wireless communications that involve modifying the bit rate of a real-time stream at a station (STA) to improve power usage efficiency and maintain stream quality.

  • The STA determines the average wake duration within an interval for communications with an access point (AP) and compares it to a target active duration for efficient power usage.
  • The STA may learn the scheduling pattern of the AP and reduce the bit rate to eliminate the need for a portion of the wake duration with lower data transmissions.
  • Modifying the bit rate helps adjust the active duration of the STA to be closer to the target active duration while maintaining a similar quality of the real-time stream.

Potential Applications

This technology could be applied in:

  • Wireless communication systems
  • Internet of Things (IoT) devices
  • Real-time streaming services

Problems Solved

  • Efficient power usage in wireless communications
  • Maintaining stream quality while adjusting active duration

Benefits

  • Improved power efficiency
  • Enhanced quality of real-time streams
  • Optimization of data transmission

Potential Commercial Applications

Optimized wireless communication systems for:

  • Smart homes
  • Industrial IoT applications
  • Video streaming services

Possible Prior Art

There may be prior art related to optimizing power usage in wireless communications systems, but specific examples are not provided in the abstract.

Unanswered Questions

== How does the STA determine the average wake duration within an interval for communications with the AP? The abstract mentions that the STA determines the average wake duration, but it does not specify the exact method or algorithm used for this calculation.

== What specific techniques are used to adjust the active duration of the STA to be closer to the target active duration? While the abstract mentions modifying the bit rate to adjust the active duration, it does not detail the specific techniques or algorithms employed for this purpose.


Original Abstract Submitted

Methods, systems, and devices for wireless communications are described. The described techniques generally provide for modifying a bit rate of a real-time stream at a station (STA). The STA may determine an average wake duration within an interval for communications with an access point (AP), and may compare the average to a target active duration for efficient power usage. In some other cases, the STA may learn a scheduling pattern of the AP, and may reduce the bitrate to eliminate the need for a portion of the wake duration having relatively lower data transmissions. Modifying the bit rate may support adjusting the active duration of the STA to be closer to the target active duration while maintaining a similar quality of the real-time stream (such as, a lossless stream).
