Wireless Communication Device Packet Reconstruction for TWS Earphones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited antenna space in small-sized TWS wireless earphones restricts their receiving ability, often resulting in incomplete packet reception, which suppresses their performance.
Innovation Solution
A wireless communication method and device that reconstructs complete packets from error packets by selecting and combining portions of data groups that fail error checking, using techniques such as bit value selection based on frequency or signal quality to form a reconstruction data group.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the antenna size is reduced to achieve small device form factor, then the device size is reduced, but the receiving ability deteriorates
Solution Approach 1:
The patent segments a complete data packet into multiple data groups for transmission. By dividing the packet into segments, the system can reconstruct the complete packet even when some segments are received with errors, thereby compensating for the limited receiving ability of small antennas.
Solution Approach 2:
The patent changes the transmission parameter by using multiple data groups instead of transmitting a single complete packet. This parameter change allows the system to tolerate reception errors by having redundant data groups that can be combined to reconstruct the original packet.
2Volume of moving object
If the antenna receiving ability is limited due to small size, then the device form factor is maintained, but packet reception completeness deteriorates
Solution Approach 1:
By segmenting packets into multiple data groups, the patent ensures that even if the antenna cannot receive a complete packet due to size limitations, sufficient information can be gathered from multiple partial receptions to reconstruct the complete packet.
Solution Approach 2:
The patent converts the harmful effect of limited antenna receiving ability into a benefit by using the same limitation to justify a transmission strategy where multiple data groups are sent. The antenna's inability to receive complete packets in single transmissions is compensated by receiving multiple incomplete packets that can be combined to form complete data.
3Reliability
If multiple data groups are transmitted to compensate for limited receiving ability, then the receiving reliability is improved, but the transmission complexity increases
Solution Approach 1:
The patent manages transmission complexity by systematically segmenting packets into data groups with specific structures including sequence information and error checking codes. This structured segmentation makes the complexity manageable through automated processing of standardized data group formats.
Solution Approach 2:
Each data group contains embedded error checking codes and sequence information that enable automatic identification and reconstruction without complex external intervention. The data groups self-identify their position and validity, reducing the complexity of the overall transmission system.
Data Source
AI summary
A non-transitory computer readable medium storing at least one program, wherein a wireless communication method is performed while the program is executed. The wireless communication method comprises: (a) receiving a plurality of data groups, wherein the data groups do not pass an error checking procedure; (b) selecting a portion of at least one of the data groups; and (c) reconstructing a reconstruction data group based on the portions selected in the step (b).
