Uplink Packet Delay Measurement Report Thresholding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in reliably transmitting uplink packet delay measurement reports, as existing methods may not provide sufficient delay information due to reliance on the ratio of excessive delayed packets, which can be unreliable if the number of measured packets is small.
Innovation Solution
User Equipment (UE) checks if the uplink packet delay measurement result is obtained from an enough number of samples before reporting it to the eNodeB, ensuring the reliability of the measurement by using a sample threshold to determine the meaningfulness of the measurement result.

Engineering Contradiction Analysis
1Reliability
If the UE reports uplink packet delay measurement results based on the ratio of excessive delayed packets, then the reporting process is simple, but the reliability of the measurement report is insufficient when the number of measured packets is small
Solution Approach 1:
The patent applies preliminary action by requiring the UE to check whether the number of measured packets meets a predefined threshold before generating the measurement report. This preliminary check ensures that only statistically meaningful measurements are reported, thereby improving reliability without adding complex processing during the reporting phase. The threshold verification is performed in advance, preventing unreliable reports from being generated in the first place.
2Reliability
If the UE checks the number of samples before reporting, then the reliability of the measurement report is improved, but the reporting process becomes more complex
Solution Approach 1:
The patent implements self-service by enabling the UE to autonomously evaluate its own measurement data quality through the sample number check. The UE independently determines whether its measurements meet the reporting criteria without requiring external validation or complex coordination with the network side. This self-evaluation mechanism maintains operational simplicity while ensuring report reliability.

The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting an UL packet delay measurement report in a wireless communication system, the method comprising: receiving a measurement configuration including a measurement period and a plurality of sample thresholds configured for each QCI from an eNB, performing an UL packet delay measurement for a QCI based on queuing delays of a plurality of PDCP SDUs from radio bearers associated with the QCI during the measurement period, checking whether a number of the plurality of PDCP SDUs is larger than a sample threshold configured for the QCI among the plurality of sample thresholds, and transmitting an UL packet delay measurement report for the QCI including the QCI and a result of the UL packet delay measurement for the QCI to the eNB, if the number of the plurality of PDCP SDUs is larger than the sample threshold configured for the QCI.
