Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communications systems lack explicit definitions for reporting reference signal beams based on signal strength thresholds, leading to ambiguity about which beams are reported, which hinders efficient resource scheduling.

Engineering Contradiction Analysis
1Productivity
If explicit signal strength thresholds and beam grouping are implemented through control signaling, then reporting clarity and resource scheduling efficiency are improved, but device complexity and signaling overhead increase
Solution Approach 1:
The patent segments reference signal beams into multiple signal strength groups based on threshold comparisons. Each group contains beams with similar signal strength characteristics, allowing the network to selectively report and schedule resources for specific groups rather than processing all beams uniformly. This segmentation improves scheduling efficiency by focusing resources on the most relevant beam groups while reducing overall processing complexity.
Solution Approach 2:
The patent changes the parameter of beam reporting from a single unified report to multiple group-specific reports with different quantities. The network configures distinct threshold values and quantity parameters for each signal strength group, allowing flexible adaptation to different channel conditions and UE capabilities. This parameter differentiation resolves the contradiction by enabling efficient resource allocation without requiring complex processing of all beams at once.
2Measurement precision
If the quantity of reference signal beams to report is configured for each signal strength group, then reporting precision and beam selection accuracy are improved, but information processing overhead and latency increase
Solution Approach 1:
The patent applies partial action by configuring the UE to report only a specific quantity of beams for each signal strength group rather than all detected beams. The network can set different quantity limits for different groups (e.g., report 3 beams for strong signal groups, 1 beam for weak signal groups). This partial reporting approach maintains beam selection accuracy for critical groups while reducing overall processing time and latency.
Solution Approach 2:
The network performs preliminary action by pre-configuring threshold values and quantity parameters for each signal strength group before the UE performs beam measurement and reporting. This advance configuration allows the UE to quickly classify beams into groups and apply pre-determined reporting quantities without performing complex real-time decisions, thereby reducing reporting latency while maintaining precision.
3Adaptability or versatility
If multiple signal strength groups with different threshold configurations are used, then adaptability to different channel conditions is improved, but system complexity and configuration overhead increase
Solution Approach 1:
The patent creates a universal framework where a single control signaling mechanism handles multiple signal strength groups with different threshold configurations. The same RRC message structure and reporting procedures are used across all groups, allowing the system to adapt to various channel conditions without requiring separate specialized protocols for each scenario. This multi-functionality approach improves adaptability while controlling complexity through standardized procedures.
Solution Approach 2:
The patent introduces dynamics by allowing the network to flexibly configure and update threshold values and group parameters based on current channel conditions and UE feedback. The system can dynamically adjust the number of groups, their threshold levels, and reporting quantities without requiring system reconfiguration. This dynamic capability enables high adaptability to changing conditions while keeping the base system structure relatively simple.

AI summary
Methods, systems, and devices for wireless communications are described. Generally, the described techniques may enable a user equipment (UE) to receive control signaling indicating a first signal strength threshold and a second signal strength threshold that define multiple signal strength groups. The control signaling may further indicate a quantity of reference signal beams for each group of the signal strength groups for the UE to report. In some examples, the UE may report a quantity of reference signals for each group per antenna module of the UE. Reporting a combination of reference signal beams with relatively high and relatively low signal strengths relative to the signal strength thresholds, may enable a network entity to schedule resources more efficiently.
