Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beam failure detection and candidate beam detection techniques in 3GPP networks provide incorrect results for certain new band combinations, particularly in FR1+FR2 NR-DC with inter-band CA, leading to inappropriate allocation of searcher resources.
Innovation Solution
A new method for calculating evaluation period extension factors PBFD and PCBD, considering configurations for PCell, PSCell, and SCells, allowing for optimized allocation of searcher measurement resources based on specific beam management operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing beam failure detection and candidate beam detection techniques are used in new band combinations, then beam management can be performed, but incorrect results are obtained leading to inappropriate allocation of searcher resources
Solution Approach 1:
The patent modifies the calculation parameters for evaluation period extension factors (PBFD and PCBD) by introducing new configuration considerations for PCell, PSCell, and SCells. This changes the mathematical parameters used in beam management to produce correct results for new band combinations, directly resolving the measurement precision and reliability contradiction.
2Productivity
If searcher resources are allocated without considering specific band combinations, then resource allocation can be performed, but beam management efficiency is reduced in FR1+FR2 NR-DC with inter-band CA scenarios
Solution Approach 1:
The patent applies different evaluation period extension factor calculations for different cell types (PCell, PSCell, SCells) and different band combinations. This local differentiation optimizes beam management efficiency for specific scenarios like FR1+FR2 NR-DC with inter-band CA while maintaining appropriate complexity only where needed.
