Beam Measurement Reporting Using TriggerQuantity Sorting in NR
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in efficiently sorting beam level measurements for both event-triggered and periodic reports in New Radio (NR) networks, particularly when multiple measurement quantities and RS types are configured, leading to ambiguous sorting criteria and increased reporting overhead.
Innovation Solution
A unified parameter, 'triggerQuantity', is introduced in the reportConfig to standardize the sorting of beam level measurements across various event types, ensuring consistent reporting based on RSRP, RSRQ, or SINR, regardless of the RS type used, thereby simplifying the UE's reporting behavior and reducing unnecessary measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple measurement quantities and RS types are configured for beam level measurements, then measurement versatility and adaptability are improved, but sorting criteria become ambiguous and device complexity increases
Solution Approach 1:
The triggerQuantity parameter is designed to serve multiple functions: it acts as the triggering condition for measurement reporting events and simultaneously serves as the sorting criterion for beam level measurements. This multi-functional parameter resolves the ambiguity by providing a unified basis for both event triggering and measurement sorting, regardless of the RS type or measurement quantity configured.
2Measurement precision
If comprehensive beam level measurements are reported for all cells, then measurement precision and reliability are improved, but reporting overhead increases
Solution Approach 1:
The patent applies local quality by selectively reporting beam level measurements based on the sorting criterion. Instead of reporting all measurements uniformly, the system identifies and reports only the beam with the highest measurement value (or top N beams) according to the triggerQuantity criterion. This localized reporting approach maintains measurement precision for the most relevant beams while reducing overall reporting overhead.
3Adaptability or versatility
If separate sorting criteria are used for different event types, then adaptability to specific event requirements is improved, but device complexity and configuration difficulty increase
Solution Approach 1:
The triggerQuantity parameter is designed as a universal sorting criterion that works across all event types (A3, A4, A5, etc.). Instead of configuring separate sorting criteria for each event type, the same parameter serves all events, simplifying configuration while maintaining adaptability through the event-specific triggering conditions themselves.
