UE Multi-Rx Beam Measurement in FR2 With Reduced Sampling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio resource management (RRM) systems in high frequency bands like FR 2 require a relatively long time for measurements due to scaling factors, limiting simultaneous reception and measurement of multiple beams.
Innovation Solution
A terminal (UE) equipped with multiple reception systems simultaneously receives synchronization signal blocks or reference signals, reducing the number of samples needed for measurement and applying common or separate transmission configuration indications to manage TCI states effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If scaling factors are applied to FR 2 for RRM measurements, then measurement reliability is improved, but measurement time increases
Solution Approach 1:
The patent applies dynamic adjustment of measurement parameters based on reception system capabilities. When multiple reception systems are available, the terminal dynamically reduces the number of samples required for measurement, thereby decreasing measurement time while maintaining reliability through the combined capability of multiple reception systems.
Solution Approach 2:
The patent changes the measurement parameter (number of samples) based on the frequency range and reception system configuration. For FR2 with multiple reception systems, the sample count is reduced compared to single reception system operation, optimizing the balance between measurement reliability and speed.
2Productivity
If multiple beams are simultaneously received, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent segments the beam reception process into multiple independent reception systems (Rx chains). Each reception system processes a subset of beams independently, allowing simultaneous reception of multiple beams without requiring a single complex processing path, thus improving productivity while managing device complexity through modular architecture.

AI summary
A terminal simultaneously receives a synchronization signal block or a reference signal using a plurality of reception systems. The terminal reduces a number of samples used for measurement, when the terminal receives the synchronization signal block or the reference signal using the plurality of reception systems in a second frequency range having a frequency band which is higher than a frequency band of a first frequency range, compared to when the terminal receives the synchronization signal block or the reference signal using a single reception system in the second frequency range. The terminal reduces the number of samples when a group-based beam reporting function is applied.
