RRM Measurement Configuration for Disable-Able Reference Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dynamically switching spatial units in radio communication systems can lead to changes in reference signals, affecting the validity of Radio Resource Management (RRM) measurements and increasing energy consumption at base stations.
Innovation Solution
Implementing a method to differentiate between disable-able and non-disable-able reference signals, where the network device configures measurement and reporting based on the measurement results of these signals, ensuring that only relevant measurements are reported, thereby optimizing energy usage and reducing unnecessary reporting.

Engineering Contradiction Analysis
1Use of energy by moving object
If dynamically switching spatial units (antenna units, ports, TRX chains, beams, panels) is implemented to reduce energy consumption, then energy consumption of base stations is reduced, but the actually-transmitted reference signals change which affects the validity of RRM measurements
Solution Approach 1:
The patent segments reference signals into two categories: first-category reference signals (disable-able) and second-category reference signals (non-disable-able). This segmentation allows the system to distinguish between reference signals that can be dynamically disabled during spatial unit switching and those that cannot, thereby maintaining measurement reliability while enabling energy savings through selective disabling of appropriate reference signals
Solution Approach 2:
The patent applies different properties to different reference signals based on their category. First-category reference signals are configured to be disable-able and can be selectively turned off during spatial unit switching, while second-category reference signals maintain their transmission. This local differentiation ensures that only the appropriate reference signals are affected by spatial unit changes, preserving measurement validity where needed
2Quantity of substance
If all reference signal measurement results are reported to ensure complete measurement data, then measurement completeness is improved, but unnecessary reporting increases energy consumption and system complexity
Solution Approach 1:
The patent extracts and identifies first-category reference signals as disable-able signals that can be selectively excluded from mandatory reporting. By taking out these specific category of reference signals from the universal reporting requirement, the system reduces unnecessary reporting overhead and energy consumption while maintaining completeness for second-category reference signals that require measurement reporting
