PDCP Information Exchange for Coordinated XR Data Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing communication technologies, protocol layer entities operating independently for different data radio bearers in extended reality (XR) and cloud gaming (CG) services lead to resource wastage and low data processing efficiency due to independent packet loss and integrity protection, lacking coordination between different QoS flows.
Innovation Solution
Implementing information exchange between protocol layer entities within the same communication device to coordinate the processing of data packets or groups, allowing for improved data processing efficiency and reduced resource waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If protocol layer entities operate independently for different data radio bearers, then each entity can process data packets autonomously, but resource waste increases and data processing efficiency decreases
Solution Approach 1:
The patent merges the independent operations of multiple PDCP entities by establishing an information exchange mechanism where they share data packet status information. This allows coordinated processing across different data radio bearers while maintaining the autonomous processing capability of each entity, thereby improving overall data processing efficiency and reducing resource waste.
2Device complexity
If protocol layer entities operate independently for different data radio bearers, then implementation complexity is reduced, but resource waste increases
Solution Approach 1:
The patent introduces a feedback mechanism where PDCP entities exchange information about data packet processing status. This feedback loop enables entities to coordinate their operations and avoid redundant processing, reducing resource waste while maintaining relatively simple implementation through standardized information exchange protocols.
3Reliability
If independent packet loss and integrity protection operations are performed, then each QoS flow is protected individually, but coordination between different QoS flows is lost
Solution Approach 1:
The patent makes the PDCP entities universal by enabling them to perform both individual QoS flow protection and coordinated processing. Through the information exchange mechanism, each entity maintains its ability to protect its own data packets while simultaneously contributing to coordinated operations across multiple QoS flows, achieving multi-functionality.
