Reference Signal Measurement with Skipped Sync Signal Occasions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminal devices are unable to simultaneously measure CSI-RS and SSB, leading to increased measurement delays due to the need to measure these signals alternately, which is undesirable for mobility management and beam tracking.
Innovation Solution
A device receives a measurement configuration that allows it to measure reference signals at designated occasions while skipping synchronization signal measurements under certain conditions, such as synchronization validity or cell synchronization, thereby reducing measurement delay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If terminal devices measure CSI-RS and SSB simultaneously, then measurement precision and beam information quality are improved, but device complexity increases due to inability to support simultaneous reception
Solution Approach 1:
The patent segments the measurement process into two distinct parts: SSB-based synchronization and timing acquisition performed first, followed by CSI-RS-based channel state measurement. This segmentation allows the terminal to perform measurements sequentially rather than simultaneously, reducing device complexity while maintaining measurement precision through proper timing alignment between the two measurement phases.
Solution Approach 2:
The patent applies preliminary action by requiring the terminal to complete SSB measurement and acquire synchronization timing information before proceeding to CSI-RS measurement. This preliminary synchronization step ensures that the terminal is properly aligned to receive and measure CSI-RS signals, thereby maintaining measurement precision without requiring simultaneous reception capability.
2Device complexity
If terminal devices measure CSI-RS and SSB alternatively, then device complexity is reduced, but measurement delay increases
Solution Approach 1:
The patent implements periodic action by configuring periodic measurement occasions for both SSB and CSI-RS with aligned time structures. The network configures measurement timing such that SSB measurement occasions and CSI-RS measurement occasions occur in a periodic, coordinated manner, allowing the terminal to efficiently switch between measurements without excessive delay while maintaining manageable device complexity.
Solution Approach 2:
The patent applies dynamics by enabling the terminal to dynamically adjust its measurement behavior based on configured parameters and current synchronization state. The terminal can adaptively determine when to perform SSB measurements versus CSI-RS measurements based on whether synchronization is already established, optimizing the measurement sequence to minimize delay while keeping device complexity manageable.
3Reliability
If terminal devices perform alternative measurement of CSI-RS and SSB, then power consumption is increased due to repeated synchronization checks, but measurement reliability is maintained
Solution Approach 1:
The patent extracts the synchronization function from the regular measurement loop by having the terminal perform SSB-based synchronization separately and store the timing information for reuse during CSI-RS measurement periods. This extraction eliminates the need for repeated synchronization checks during each CSI-RS measurement, maintaining measurement reliability through the stored synchronization data while significantly reducing power consumption by avoiding redundant processing.
Solution Approach 2:
The patent implements self-service by enabling the terminal to use its own previously acquired synchronization timing information to guide subsequent CSI-RS measurements without needing continuous external synchronization signals. The terminal serves itself by reusing stored synchronization data, thereby maintaining measurement reliability while reducing power consumption by eliminating repeated synchronization acquisition attempts.
