Wireless Slave Device Peer Packet Retransmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless earbuds using Bluetooth connectivity often experience packet loss due to environmental interference, leading to incomplete audio transmission.
Innovation Solution
A method for retransmitting wireless peer packets, where a first wireless slave device receives and temporarily stores media packets originally sent by a wireless master device to a second wireless slave device. When a retransmission mechanism is activated, the first wireless slave device converts and transmits the stored media packets as radio frequency signals during the peer-side time period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If media packets are transmitted directly from the wireless master device to the second wireless slave device, then the transmission path is simple and device complexity is low, but packet loss occurs due to environmental interference
Solution Approach 1:
The first wireless slave device acts as an intermediary node that receives media packets from the wireless master device and retransmits them to the second wireless slave device. This mediator approach allows the system to overcome direct transmission limitations and environmental interference by introducing a relay device that can forward packets through alternative paths.
Solution Approach 2:
The first wireless slave device preliminarily receives and buffers media packets from the wireless master device before the original transmission to the second wireless slave device completes. This preliminary action enables the device to have packets ready for retransmission if the original transmission fails due to interference, thereby improving reliability.
2Reliability
If the first wireless slave device receives and retransmits media packets during the peer-side time period, then packet loss is reduced, but the time synchronization and coordination complexity increases
Solution Approach 1:
The system uses periodic time periods including peer-side time periods and non-peer-side time periods for structured packet transmission and retransmission. This periodic action allows devices to switch between receiving original transmissions and retransmitting packets in an organized manner, reducing time coordination overhead through predictable patterns.
Solution Approach 2:
The first wireless slave device dynamically switches between different operational modes: receiving packets from the master device during certain time periods and retransmitting packets to the second slave device during peer-side time periods. This dynamic behavior allows the system to adapt to transmission needs while maintaining time synchronization through structured period transitions.
3Reliability
If a retransmission mechanism is activated between the wireless master device and the second wireless slave device, then packet loss is addressed, but the communication protocol complexity increases
Solution Approach 1:
The first wireless slave device serves as an intermediary that simplifies the retransmission protocol by handling packet forwarding locally. Instead of requiring complex end-to-end retransmission protocols between the master and second slave device, the intermediary approach allows simpler local retransmission operations, reducing overall protocol complexity.
Solution Approach 2:
The first wireless slave device receives copies of media packets from the wireless master device and uses these copies for retransmission to the second wireless slave device. This copying mechanism allows the retransmission system to operate independently without requiring complex protocol modifications to the original transmission path, thereby reducing protocol complexity.

AI summary
The invention relates to methods, non-transitory computer-readable storage medium, and apparatus for retransmitting wireless peer packets. A method for retransmitting wireless peer packets, which is performed by a processing unit of a first wireless slave device, includes: receiving a media packet that is originally sent by a wireless master device to a second wireless slave device in a peer-side time period; and transmitting the media packet in a medium in the peer-side time period when a retransmission mechanism is activated between the wireless master device and the second wireless slave device for retransmitting the media packet. The first wireless slave device and the second wireless slave device are mutually peer devices. The peer-side time period indicates a time period that is originally used by the second wireless slave device communicating with the wireless master device.
