5G UE Measurement Threshold for Beam Timeliness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G and NR communication systems, the introduction of multiple beams complicates measurement processes for User Equipment (UE), as traditional measurement thresholds based on serving cell quality alone are insufficient, potentially leading to delayed or inadequate measurements, which can result in radio link failures.
Innovation Solution
A measurement method that incorporates a configured threshold related to both cell quality and the number of qualified beams, allowing User Equipment to determine whether to perform measurements more comprehensively, ensuring timely measurements by considering the number of qualified beams in addition to cell quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If measurement is performed based on s-Measure (cell quality threshold) only, then measurement triggering is simple, but measurement timeliness is insufficient due to beam introduction in 5G/NR
Solution Approach 1:
The measurement threshold is segmented into multiple independent components: s-Measure (cell quality threshold) and beam quantity threshold. These components can be independently configured and evaluated, allowing the UE to assess both cell quality and beam availability separately, thereby improving measurement timeliness without excessive complexity
Solution Approach 2:
The measurement triggering mechanism transitions from a single-dimension (cell quality only) to a multi-dimensional approach by incorporating beam quantity as an additional dimension. This allows the system to evaluate measurement needs based on both quality and quantity metrics, addressing the timeliness issue in beam-based 5G/NR systems
2Reliability
If measurement threshold only considers cell quality, then configuration is simple, but measurement reliability is insufficient in beam-based systems
Solution Approach 1:
The measurement threshold configuration is segmented into distinct parameters: s-Measure for cell quality and beam quantity threshold for beam availability. This segmentation allows each parameter to be optimized independently, improving measurement reliability through more comprehensive assessment while managing configuration complexity through modular design
Solution Approach 2:
The system changes the measurement threshold parameters from a single quality-based value to multiple parameters including quality threshold and beam quantity threshold. This parameter expansion enables more reliable measurement decisions in beam-based systems by considering both signal quality and beam availability
3Loss of time
If UE performs frequent measurements to ensure timeliness, then measurement timeliness improves, but energy consumption increases
Solution Approach 1:
The UE performs measurements selectively based on threshold conditions rather than continuously. By using partial action (measuring only when thresholds are met), the system achieves adequate measurement timeliness while significantly reducing unnecessary energy consumption associated with continuous measurements
Solution Approach 2:
The measurement triggering mechanism incorporates feedback through threshold evaluation. The UE continuously monitors cell quality and beam quantity, and only initiates measurements when predefined thresholds are met, creating an efficient feedback loop that balances timeliness with energy conservation
