Synchronization Signal Block Prioritization for Beam Measurement Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face performance issues due to conflicts in beam measurements, leading to poor system performance and user experience, particularly when the number of radio frequency events exceeds the beam switch capability limit of user equipment (UE) during a transmission time interval.
Innovation Solution
The described techniques prioritize synchronization signal blocks based on beam switch events, allowing the UE to determine a priority order and perform beam measurements only on high-priority blocks, dropping or rescheduling low-priority measurements to maintain system efficiency and reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the UE monitors all synchronization signal blocks during the transmission time interval, then measurement completeness is improved, but the number of beam switch events exceeds the beam switch capability limit causing measurement conflicts
Solution Approach 1:
The patent segments the set of synchronization signal blocks into multiple priority groups (first priority, second priority, third priority) based on their importance for beam measurement. This segmentation allows the UE to selectively measure blocks in descending order of priority when beam switch capability is exceeded, resolving the contradiction between measurement completeness and beam switch limitations by prioritizing critical measurements while dropping less critical ones.
2Reliability
If the UE performs beam measurements on all synchronization signal blocks, then system performance monitoring is improved, but power consumption increases due to excessive beam switch events
Solution Approach 1:
The patent extracts and identifies the essential synchronization signal blocks that must be measured for reliable system performance monitoring by assigning priorities based on beam switch events and capability limits. Instead of measuring all blocks, the UE selectively measures only those necessary blocks in priority order, thereby maintaining system performance monitoring reliability while significantly reducing power consumption from excessive beam switching.
3Productivity
If the UE prioritizes synchronization signal blocks based on beam switch events, then measurement efficiency is improved, but complexity increases in determining priority order
Solution Approach 1:
The patent changes the parameter of synchronization signal block prioritization from traditional methods to being based on beam switch events and beam switch capability limits. By using the number of beam switch events as the key parameter for determining priority order, the patent simplifies the prioritization logic while improving measurement efficiency, as the UE can systematically evaluate blocks based on this clear parameter rather than complex multi-factor analysis.

AI summary
Methods, systems, and devices for wireless communications are described. The method includes receiving control signaling indicating for the UE to monitor a set of multiple synchronization signal blocks during a first transmission time interval, determining a priority order of the set of multiple synchronization signal blocks based on a number of beam switch events that occur during the first transmission time interval exceeding a beam switch capability limit of the UE, performing a set of multiple beam measurements of at least a subset of the set of multiple synchronization signal blocks that occur during the first transmission time interval according to the priority order of the set of multiple synchronization signal blocks, and transmitting a beam report to a base station based on the set of multiple beam measurements.
