Multi-Link Packet Distribution for Transmission Time Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face challenges in synchronizing transmission times of data across multiple links due to varying channel environments, which can lead to inefficiencies in multi-link communication systems.
Innovation Solution
The electronic device synchronizes transmission times by redistributing data packets across multiple links based on link-specific transmission rates and the number of packets, ensuring the difference in transmission times is within a designated range.

1Speed
If data packets are transmitted through multiple links with different transmission rates, then transmission speed is improved, but transmission time synchronization deteriorates
Solution Approach 1:
The electronic device performs preliminary calculations to determine the number of data packets to be transmitted through each link before actual transmission begins. By pre-calculating packet distribution based on link-specific transmission rates and target transmission times, the system ensures that all links complete their transmissions simultaneously without requiring real-time adjustments during the transmission process.
Solution Approach 2:
The system changes the parameter of packet distribution by adjusting the number of data packets assigned to each link based on its transmission rate. This parameter adjustment ensures that links with higher transmission rates receive fewer packets while links with lower transmission rates receive more packets, thereby synchronizing overall transmission completion times across all links.
