Threshold-Based Data Transmission Control in Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, determining the available data for transmission across multiple radio link control entities is challenging, particularly in scenarios where data needs to be split between different cell groups, and existing methods lack efficient threshold-based mechanisms for prioritizing and managing data transmission.
Innovation Solution
The method involves associating a packet data convergence protocol entity with first and second radio link control entities from different cell groups, determining the amount of data available for transmission, and comparing it with thresholds to decide whether to submit packet data convergence protocol data to one or both entities for transmission, thereby optimizing buffer status reporting and uplink grants.

Engineering Contradiction Analysis
1Duration of action of stationary object
If data is transmitted across multiple radio link control entities without threshold-based control, then data transmission continuity is improved, but transmission efficiency deteriorates due to unnecessary transmissions
Solution Approach 1:
The patent introduces threshold parameters (first threshold and second threshold) to control data transmission decisions. By comparing the amount of data in the buffer against these thresholds, the system dynamically adjusts transmission behavior, enabling efficient load control while maintaining continuous transmission when needed.
2Productivity
If threshold-based data transmission control is implemented, then transmission efficiency is improved, but system complexity increases due to additional comparison logic
Solution Approach 1:
The patent pre-configures threshold values (first threshold and second threshold) in advance through RRC signaling. This preliminary setup allows the comparison logic to operate simply during runtime, reducing real-time processing complexity while maintaining efficient transmission control.
3Reliability
If packet data convergence protocol data is submitted to multiple radio link control entities, then data transmission reliability is improved, but buffer management complexity increases
Solution Approach 1:
The patent segments buffer management by introducing separate threshold levels: a first threshold for triggering data submission to multiple radio link control entities, and a second threshold for controlling data submission to a single entity. This segmentation simplifies the decision logic for buffer management while ensuring reliable transmission through appropriate multi-path utilization.
