Wireless Data Transmission Reliability via Intermediary Retransmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless data transceiving systems, when a data source device needs to transmit data to multiple wireless transceiving devices, the reliability of data transmission is low due to unsuccessful receipt of data packets, especially if retransmissions fail after a preset number of attempts.
Innovation Solution
A method where a first device sends indication information to a second device if it fails to receive a data packet, allowing the second device or the data source to resend the packet, improving the chances of successful receipt by the first device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the data source device retransmits data packets for a preset number of times, then the reliability of data transmission is improved, but the transmission time is extended and the system complexity increases
Solution Approach 1:
The patent applies preliminary action by having the first device send indication information in advance when it fails to receive a data packet. This allows the second device or data source device to proactively retransmit the packet before the first device exhausts its retry attempts, thereby improving reliability without extending the overall transmission time significantly.
Solution Approach 2:
The patent introduces an intermediary mechanism where the first device acts as a mediator by sending indication information to the second device. This intermediary signal triggers the second device to retransmit data packets to the first device, creating an indirect transmission path that improves reliability without requiring the first device to continuously retry transmissions.
2Adaptability or versatility
If the data source device sends data packets to multiple wireless transceiving devices, then the system versatility is improved, but the data transmission reliability deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the transmission path into multiple independent routes. Instead of relying on a single direct transmission from the data source to each device, the system creates alternative paths through the first device and second device, allowing data to reach the first device through different routes (direct from data source or via second device), thereby maintaining reliability in multi-device scenarios.
Solution Approach 2:
The patent changes the transmission parameter by introducing dynamic path selection. When the first device fails to receive a data packet, it sends indication information that changes the transmission parameter from direct transmission to relayed transmission through the second device, thereby adapting the transmission path to maintain reliability in multi-device environments.
3Reliability
If the first device continuously retries to receive data packets, then the data transmission reliability is improved, but the device complexity and energy consumption increase
Solution Approach 1:
The patent introduces an intermediary mechanism where the first device sends indication information to the second device instead of continuously retrying transmissions. This intermediary approach simplifies the first device's operation by delegating the retransmission responsibility to the second device, thereby improving reliability without increasing device complexity.
Solution Approach 2:
The patent applies self-service by enabling the second device to automatically retransmit data packets to the first device when indicated by the first device. This self-service mechanism eliminates the need for the first device to continuously monitor and retry transmissions, thereby improving reliability while reducing the operational complexity and energy consumption of the first device.

AI summary
Embodiments of the present application provide a data transmission method, apparatus and device, the method includes: sending, by a first device, first indication information to a second device if the first device does not receive a data packet sent by a data source device in a first time slot successfully, where the first device and the second device are configured to receive the data packet sent by the data source device in a same time slot; receiving the data packet sent by the data source device or the second device when the second device receives the data packet sent by the data source device in the first time slot successfully; and receiving the data packet sent by the data source device when the second device does not receive the data packet sent by the data source device in the first time slot successfully. The reliability of data transmission is improved.
