UE Jitter Evaluation for Timely Packet Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Third Generation Partnership Project (3GPP) networks, devices transmitting packets to user equipment (UE) experience delays (jitter) that can cause packets to arrive late, leading to issues such as expiration before forwarding, and existing methods rely on network elements to address these delays, which is inefficient.
Innovation Solution
User equipment (UE) autonomously evaluates the delay (jitter) experienced by incoming packets and determines the appropriate transmission mode to ensure timely delivery and improve radio efficiency, rather than relying on network feedback.

Engineering Contradiction Analysis
1Reliability
If user equipment autonomously evaluates delay and determines transmission mode, then packet delivery timeliness is improved and radio efficiency is enhanced, but device complexity increases
Solution Approach 1:
The user equipment autonomously evaluates delay of incoming packets and determines the appropriate transmission mode without requiring network feedback or external control. The UE self-manages the jitter compensation process by independently assessing packet delay and selecting transmission modes (repetition or no repetition) based on evaluated delay thresholds, thereby improving packet delivery timeliness while avoiding additional network signaling overhead
Solution Approach 2:
The user equipment performs delay evaluation and transmission mode determination in advance before packet transmission, proactively compensating for potential jitter issues. By evaluating packet delay and deciding on transmission mode (including whether to use repetition) before the transmission deadline, the UE ensures timely packet delivery without waiting for network feedback or experiencing deadline misses
2Reliability
If network elements address packet delays, then packet delivery reliability is improved, but network overhead and intervention requirements increase
Solution Approach 1:
The patent extracts the jitter compensation function from the network elements and transfers it to the user equipment. Instead of network elements evaluating packet delay and controlling transmission modes, the UE independently performs delay evaluation and transmission mode determination, eliminating the need for network feedback messages and reducing signaling overhead while maintaining packet delivery reliability
