Uplink Data Transmission Timer for Dual-Branch Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In dual-connectivity architectures, when one transmission branch fails due to channel quality deterioration, data congestion occurs on that branch for a long period, leading to poor user experience.
Innovation Solution
Implement a timer-based mechanism that allows for the UE to perform a third operation on data on the failing transmission branch, such as canceling or deleting the data, and transmit a backup to another branch, thereby preventing long-term congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is allocated to multiple transmission branches in dual-connectivity architecture, then transmission reliability is improved, but data congestion occurs on failed branches leading to degraded user experience
Solution Approach 1:
The patent applies preliminary action by starting a timer when data is allocated to transmission branches before actual transmission occurs. This timer monitors the transmission status in advance, and when transmission fails on one branch, the data can be reallocated to another branch proactively, preventing long-term congestion and improving user experience while maintaining transmission reliability through multi-branch allocation
2Productivity
If data is transmitted on multiple transmission branches simultaneously, then transmission efficiency is improved, but complexity of transmission management increases
Solution Approach 1:
The patent implements feedback by using a timer mechanism that continuously monitors transmission status on each branch. When transmission fails on one branch (feedback signal), the system automatically reallocates data to another branch. This feedback-driven approach maintains high transmission efficiency through multi-branch parallel transmission while managing complexity through automated timer-based control rather than complex manual management

AI summary
Embodiments of the present invention provide an uplink data transmission method, a timer configuration method, and a related device. The uplink data transmission method is applied to user equipment, and includes: starting a timer when a first operation is performed on first data on a first transmission branch; and when timing of the timer ends, if a second operation is not performed on second data on a second transmission branch, performing a third operation on the second data. Preprocessed data can be allocated to two transmission branches by the user equipment. In this way, data is prevented from being congested on one transmission branch for a long period when transmission on the transmission branch fails due to channel quality deterioration, thereby improving user experience.
