Bluetooth Link Idle Slot Private Packet Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Bluetooth communication technology suffers from high latency, which is not suitable for real-time and low-latency signal transmission required in audio and video communication applications, such as wireless microphones and gaming headsets. Additionally, existing low-latency audio interaction schemes lack compatibility with standard Bluetooth protocols, limiting their application range and increasing development costs.
Innovation Solution
The proposed solution involves segmenting signal data into private-chain packets and transmitting them in the idle time slots of standard Bluetooth packets. This method includes compression-encoding the signal data, determining the signal modulation mode based on the type of standard Bluetooth packet, and reducing the transmission frequency of command Bluetooth packets to optimize data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard Bluetooth communication protocol is used, then compatibility and ease of operation are improved, but signal transmission latency increases
Solution Approach 1:
The patent segments the transmission time into different time slices, with first time slices dedicated to standard Bluetooth packets for compatibility and second time slices dedicated to private-chain packets for low-latency transmission. This temporal segmentation allows the system to simultaneously maintain compatibility with standard Bluetooth protocols while enabling low-latency communication channels for audio and video data.
Solution Approach 2:
The patent introduces a temporal dimension to the communication protocol by creating multiple transmission channels operating in different time dimensions. The first transmission channel uses standard Bluetooth packets during first time slices, while the second transmission channel uses private-chain packets during second time slices, effectively adding a time-based layer to the communication architecture.
2Loss of time
If low-latency audio interaction schemes are developed for specific applications, then signal transmission latency is reduced, but compatibility and ease of operation deteriorate
Solution Approach 1:
The patent creates a universal communication framework where Bluetooth devices can operate in multiple modes - standard Bluetooth mode for compatibility and private-chain packet mode for low-latency performance. The system can dynamically switch between or combine these modes based on application requirements, making the solution applicable to both general Bluetooth communication and specialized low-latency audio/video applications.
Solution Approach 2:
The patent introduces private-chain packets as an intermediary transmission mechanism that bridges the gap between standard Bluetooth protocols and low-latency requirements. These private-chain packets serve as a mediator that carries audio and video data with reduced latency while still operating within the broader Bluetooth ecosystem, allowing compatibility with standard protocols while achieving performance goals.
3Loss of time
If private-chain packets are transmitted in idle time slots, then signal transmission latency is reduced, but device complexity increases
Solution Approach 1:
The patent enables devices to self-manage the dual transmission mode by implementing local logic that determines when to send standard Bluetooth packets versus private-chain packets. The device autonomously handles packet segmentation, timing synchronization, and transmission mode selection based on the defined time slice structure, reducing the need for complex external coordination or control infrastructure.

AI summary
A Bluetooth communication method, a Bluetooth communication device, and a Bluetooth communication system are provided. The Bluetooth communication method comprises: segmenting a first signal data based on a length of a first time slice, performing a compression-encoding to construct a plurality of first private-chain packets; constructing and transmitting a plurality of first-standard Bluetooth packets, and transmitting one of the plurality of first private-chain packets to a second terminal of a device of the link in an idle time of a transmission slot in which one corresponding first-standard Bluetooth packet is transmitted, so that the second terminal of the device obtains the first signal data by decoding the corresponding first private-chain packet. The above method transmits the signal data in the idle time, thereby improving the efficiency of signal transmission and reducing communication latency.
