Air-Interface SDU Grouping to Avoid Unnecessary Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing data unit processing methods in 5G user plane air-interface protocols for XR services result in unnecessary data transmission over the air interface, leading to reduced transmission efficiency.
Innovation Solution
The target air-interface protocol layer determines the association relationship between service data units (SDUs) based on first indication information and discards multiple SDUs and/or corresponding protocol data units (PDUs) when at least one SDU needs to be discarded or is not successfully transmitted, utilizing timers, congestion indication, and configuration information to optimize data transmission.

Engineering Contradiction Analysis
1Productivity
If individual SDU processing is performed as in related art, then processing simplicity is maintained, but transmission efficiency deteriorates due to unnecessary data transmission
Solution Approach 1:
The patent merges multiple individual SDU processing operations into a single batch processing operation. By identifying associations between SDUs and processing them as a group, the system performs one discard decision for multiple SDUs simultaneously, reducing the number of processing operations and improving transmission efficiency without significantly increasing complexity
Solution Approach 2:
The patent performs preliminary identification of SDU associations before the actual transmission decision. By pre-establishing the association relationships between SDUs based on indication information, the system prepares for efficient batch processing, allowing the processing layer to quickly determine which groups of SDUs should be discarded together without complex real-time analysis
2Loss of energy
If all SDUs are transmitted individually, then data completeness is maintained, but system resource utilization deteriorates due to unnecessary transmissions
Solution Approach 1:
The patent implements a feedback mechanism where the processing layer receives indication information about SDU associations and uses this feedback to make intelligent discard decisions. The system continuously monitors transmission status and adjusts its discard decisions based on feedback about which SDUs are successfully transmitted and which are not, optimizing resource utilization while maintaining data completeness for successfully transmitted SDUs
Solution Approach 2:
The patent changes the processing parameter from individual SDU handling to batch SDU handling based on association relationships. By modifying the fundamental processing unit from single SDU to grouped SDUs, the system reduces unnecessary transmissions and improves resource utilization while ensuring that complete data sets are either all transmitted or all discarded based on their association status
Data Source
AI summary
The present disclosure provides a data unit processing method and apparatus, and a communication device. The method comprises: a target air-interface protocol layer of a communication device determines an association relationship between service data units (SDUs) according to first indication information; among multiple SDUs with the association relationship, if there is at least one SDU that needs to be discarded or is not successfully transmitted, then the multiple SDUs with the association relationship and/or protocol data units (PDUs) corresponding to the multiple SDUs with the association relationship are discarded.
