Beam Measurement Resource Configuration for L1-SINR Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication technologies only consider Layer 1-Signal to Interference plus Noise Ratio (L1-RSRP) for beam measurement, neglecting interference and lacking a mechanism to configure channel and interference measurement resources, which results in suboptimal beam selection.
Innovation Solution
Configuring additional resources for channel and interference measurement at the terminal, allowing for the calculation and reporting of Layer 1-Signal to Interference plus Noise Ratio (L1-SINR) to enable more accurate beam selection based on interference levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only L1-RSRP measurement resources are configured for beam measurement, then the measurement process is simple, but the beam selection accuracy is insufficient because interference cannot be measured
Solution Approach 1:
The patent segments the measurement resources into distinct types: channel measurement resources (CMR) for signal quality measurement and interference measurement resources (IMR) for interference measurement. This segmentation allows independent configuration and optimization of each measurement type, enabling accurate beam selection through L1-SINR calculation while maintaining clear resource management
Solution Approach 2:
The patent adds a new dimension to beam measurement by introducing interference measurement resources (IMR) as a separate measurement dimension. Instead of only measuring channel quality (L1-RSRP), the system now measures both channel quality and interference levels, creating a two-dimensional measurement space that enables more accurate beam selection through L1-SINR calculation
2Reliability
If additional channel and interference measurement resources are configured, then L1-SINR can be calculated for more accurate beam selection, but the measurement resource complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring channel measurement resources (CMR) and interference measurement resources (IMR) before beam measurement operations. The network device establishes these measurement resource configurations in advance, associating them with specific reference signals (CSI-RS or SSB), so that when beam measurement is needed, the terminal can immediately perform L1-SINR calculation without additional resource setup overhead
Solution Approach 2:
The patent creates universal measurement resource configurations that can serve multiple purposes. The same CMR and IMR configurations can be reused across different beam measurement scenarios, different terminal devices, and different time instances. The measurement resources are associated with reference signal types (CSI-RS/SSB) rather than specific beams, enabling flexible and efficient resource utilization
