Dynamic Measurement Gap Prioritization for Wireless UE
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in managing measurement gaps, which prioritize signal measurement over data traffic, leading to delays and difficulties in meeting packet delay budget requirements, especially in high-data-rate and low-latency applications like extended reality multimedia services.
Innovation Solution
Implementing an enhanced measurement gap procedure that selectively prioritizes data traffic processing over measurement procedures in certain cases, allowing for dynamic reconfiguration of user equipment to maintain data transmission while still performing necessary measurements, such as inter-cell interference assessments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement procedures are prioritized over data traffic during measurement gaps, then measurement accuracy is improved, but packet delay increases and packet delay budget requirements cannot be met
Solution Approach 1:
The patent implements dynamic prioritization where the UE can switch between prioritizing measurement procedures and prioritizing data traffic based on current conditions. The network can configure different priority levels, and the UE can dynamically adjust its behavior during measurement gaps to balance measurement accuracy with packet delay requirements, particularly for urgent data traffic.
Solution Approach 2:
The patent changes the priority parameter of measurement procedures from fixed to configurable. The network can signal to the UE whether to prioritize measurement procedures or data traffic during measurement gaps, allowing flexible adjustment of the measurement priority parameter based on traffic conditions and service requirements.
2Reliability
If measurement procedures are performed during measurement gaps, then network optimization is improved, but data transmission performance deteriorates
Solution Approach 1:
The system dynamically adjusts the balance between measurement activities and data transmission based on current network conditions and traffic priorities. The UE can switch between modes prioritizing network optimization through measurements and modes prioritizing data transmission performance, allowing flexible adaptation to different operational requirements.
3Loss of time
If data traffic is prioritized over measurement procedures, then packet delay budget requirements are met, but measurement accuracy may be compromised
Solution Approach 1:
The network configures the priority parameter dynamically based on service requirements. For services with strict packet delay budget requirements, the network can signal the UE to prioritize data traffic over measurements during measurement gaps, while for other scenarios, measurement priority can be maintained.
