Layered Beam Measurement Reporting for Wireless Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems in LTE and NR face inefficiencies in handover decisions due to insufficient or excessive beam-related information provided by user equipment, leading to resource waste and complex processing, respectively.
Innovation Solution
Wireless devices are enabled to provide measurement reports that include beam measurement information, allowing for better network management by detecting and measuring multiple beams, generating reports with varying levels of information from L1 to L3 processing, and adjusting content based on network needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the UE reports too little beam information, then the processing complexity is reduced, but resource allocation efficiency deteriorates
Solution Approach 1:
The patent segments beam information reporting into multiple layers (L1 and L3) with different levels of detail. L1 filtering provides basic beam quality metrics while L3 filtering provides more comprehensive beam information. This segmentation allows the system to balance processing complexity with resource allocation efficiency by providing appropriate levels of information at different processing stages.
2Productivity
If the UE reports too much beam information, then resource allocation efficiency is improved, but processing complexity and configuration complexity increase
Solution Approach 1:
The patent implements dynamic beam information reporting where the amount and type of beam information included in measurement reports can be adjusted based on network needs and conditions. The network can configure different reporting modes that provide varying levels of beam detail, allowing the system to optimize between resource allocation efficiency and processing complexity dynamically rather than using a fixed reporting structure.
3Productivity
If beam specific information is provided in HO command, then access efficiency is improved, but configuration complexity increases
Solution Approach 1:
The patent applies preliminary action by performing beam measurements and filtering (both L1 and L3) before the handover decision is made. This allows the UE to prepare beam-specific measurement information in advance, so that when handover is needed, the network already has pre-processed beam information available to include in the HO command, improving access efficiency without requiring complex real-time configuration during the handover execution.
