Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face high latency issues during TWT parameter updates in extended personal audio networks, particularly in applications requiring ultra-low latency and lossless audio, due to the overhead of Bluetooth messaging and TWT teardown procedures.
Innovation Solution
A data-packet-generation-based mechanism where updated TWT parameters are embedded in downlink audio data packets, allowing direct transmission to wireless devices without additional signaling, thereby reducing latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Bluetooth messaging and TWT teardown procedures are used for TWT parameter updates, then communication reliability is maintained, but end-to-end latency increases significantly
Solution Approach 1:
The patent merges TWT parameter update messaging with existing downlink audio data packet transmissions. Instead of separate Bluetooth messaging and TWT teardown procedures, the configuration updates are embedded within the audio data stream, combining multiple functions into a single transmission channel and eliminating sequential processing delays.
Solution Approach 2:
The patent implements preliminary action by pre-configuring TWT parameters to be updated within the audio data packet structure itself. The downlink audio packets are prepared in advance to contain TWT configuration information, allowing immediate parameter updates without waiting for separate signaling exchanges or teardown procedures to complete.
2Adaptability or versatility
If separate Bluetooth messaging is used for TWT parameter updates, then protocol compatibility is maintained, but device complexity increases
Solution Approach 1:
The patent implements universality by designing the downlink audio data packet structure to serve multiple functions simultaneously: audio data transmission, TWT parameter updates, and configuration signaling. This multi-functional approach eliminates the need for separate dedicated messaging protocols while maintaining compatibility with existing audio streaming frameworks.
3Stability of the object's composition
If TWT teardown procedures are implemented for parameter updates, then connection stability is maintained, but productivity decreases
Solution Approach 1:
The patent maintains continuity of useful action by keeping the audio data stream continuously active while embedding TWT parameter updates within it. Instead of tearing down and re-establishing connections for parameter updates, the system continuously transmits audio packets that carry configuration information, maintaining both connection stability and update efficiency simultaneously.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device (WCD) may communicate, via a wireless link, with an audio device using a first configuration having first values for communication parameters. The WCD may transmit an indication to switch to a second configuration based at least in part on a configuration switch trigger, the configuration switch trigger being based at least in part on one or more of a link quality metric associated with the wireless link or a change of a use state of the WCD, and the second configuration having second values for the communication parameters associated with a reduction in voltage-induced interference in an audio output of the audio device. Numerous other aspects are described.
