Beam Management Resource Grouping for Faster Beam Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current beam management techniques using CSI-RS signals for wireless communications suffer from limited spatial coverage, leading to delays and inefficiencies when radio links are blocked, making it difficult to identify new beams, especially in MIMO systems with narrow beam widths.
Innovation Solution
Incorporating synchronization signals (SS blocks) alongside CSI-RS signals to form quasi-co-located resource groups, enhancing beam coverage and efficiency by utilizing both types of signals for beam management, including grouping and associating CSI-RS and SS block resources based on shared channel properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If CSI-RS signals are used for beam management, then beam management functions can be performed, but spatial coverage is limited and delays occur when radio links are blocked
Solution Approach 1:
The patent combines CSI-RS resources and SS block resources into unified resource groups for beam management. This merging allows the system to leverage both narrowbeam CSI-RS for precise beam identification and widebeam SS blocks for broader coverage and faster initial access, thereby reducing beam identification delays while maintaining management reliability
Solution Approach 2:
The patent creates resource groups that can serve multiple beam management functions simultaneously. These unified resource groups enable both beam sweeping, beam determination, and beam reporting functions while providing both wide and narrow beam coverage, making the system more versatile and efficient in handling different beam management scenarios
2Measurement precision
If narrow beam widths are used for precise beam identification, then spatial resolution is improved, but spatial coverage is reduced
Solution Approach 1:
The patent segments beam management resources into different types (CSI-RS and SS blocks) with different beam widths, organizing them into unified resource groups. This segmentation allows the system to use narrow beams for precise identification where needed and wide beams for broad coverage elsewhere, optimizing both precision and coverage area
Solution Approach 2:
The patent applies local quality by assigning different beam characteristics to different spatial regions through the resource group structure. Narrow CSI-RS beams are used in regions requiring precise beam identification, while wide SS block beams cover regions requiring broader spatial coverage, ensuring each area receives the appropriate beam quality for its specific needs
