PDU Set Importance Signaling for Reliable Standalone PDU Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in providing Quality of Service (QoS) guarantees and user quality of experience (QoE) for extended reality and media (XRM) services due to the lack of sufficient information for processing packet data units (PDUs) that do not carry extension headers or cannot be mapped into PDU sets.
Innovation Solution
A method and apparatus for indicating packet data unit set importance (PSI) related to PDUs that do not carry extension headers or cannot be mapped into PDU sets, enabling network devices to determine corresponding PDU set information, thereby improving processing reliability and ensuring QoS and QoE.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If PDU set information is not provided for alone PDUs, then the device complexity is reduced, but the reliability of PDU processing deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-defining PDU set information (including PDU set ID, sequence number, and importance) for alone PDUs before transmission. This allows receiving devices to process these PDUs reliably without requiring complex real-time analysis, thus resolving the contradiction between simplified processing and reliable processing.
2Reliability
If PDU set information is added to alone PDUs, then the reliability of PDU processing is improved, but the device complexity increases
Solution Approach 1:
The patent applies local quality by selectively adding PDU set information only to alone PDUs that require enhanced processing reliability, rather than uniformly processing all PDUs. This targeted approach improves reliability where needed while avoiding unnecessary complexity for PDUs that don't require it.
Solution Approach 2:
The patent changes the parameter state of alone PDUs by assigning them specific PDU set information parameters (PDU set ID, sequence number, importance level). This parameterization enables simplified processing rules at receiving devices while maintaining high reliability, thus resolving the contradiction.
3Reliability
If sufficient information is provided for alone PDU processing, then the QoS guarantee is improved, but the loss of information is reduced
Solution Approach 1:
The patent applies copying by creating and transmitting PDU set information as metadata associated with alone PDUs. This copied information (PDU set ID, sequence number, importance) enables receiving devices to make informed processing decisions without losing critical QoS-related information about the alone PDUs.

AI summary
Embodiments of the present disclosure provide an information indication method and apparatus, a communication device, and a storage medium. The information indication method comprises: on the basis of first information, a fourth network device determines PSI related to an independent PDU, so that the fourth network device or other network devices can determine independent PDU -related processing on the basis of PDU set information. In this way, the reliability of processing associated with a PDU can be improved.
