Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If beam measurement is performed using traditional methods in millimeter wave and terahertz communication systems, then beam management can be achieved, but measurement accuracy and coverage are insufficient
Solution Approach 1:
The patent segments the beam measurement process by introducing class values that divide reference signals into different measurement categories. This segmentation allows for differentiated measurement approaches based on beam characteristics, improving both measurement accuracy and management reliability through structured classification.
Solution Approach 2:
The patent applies preliminary action by determining class values for reference signals before performing beam measurements. This pre-classification enables the system to prepare appropriate measurement configurations and anchor reference signals in advance, leading to more accurate and reliable beam management.
2Area of stationary object
If beam bandwidth is increased to improve coverage, then wider coverage is achieved, but measurement precision may be compromised
Solution Approach 1:
The patent applies local quality by assigning different class values to reference signals based on their specific beam characteristics and coverage requirements. This allows the system to optimize measurement precision for each local beam condition while maintaining overall coverage, rather than using a uniform measurement approach.
Solution Approach 2:
The patent changes measurement parameters dynamically by selecting different class values and anchor reference signals based on beam bandwidth and coverage requirements. This parameter adaptation enables the system to maintain measurement precision across varying beam widths and coverage areas.
3Loss of information
If multiple reference signals are measured individually, then comprehensive beam information is obtained, but measurement complexity and time consumption increase
Solution Approach 1:
The patent introduces class values as intermediaries that group and organize multiple reference signals. This intermediary classification allows the system to efficiently manage comprehensive beam information without measuring each signal individually in detail, reducing measurement time while maintaining information completeness.
Solution Approach 2:
The patent performs preliminary classification of reference signals into classes before detailed measurement. This pre-organization enables the system to efficiently process multiple reference signals by focusing detailed measurement efforts on selected anchor signals, thereby reducing overall measurement time while preserving comprehensive beam information.

AI summary
A method for measuring a beam is performed by a User Equipment (UE). The method includes: obtaining configuration information sent by a base station; obtaining, based on the configuration information, at least one reference signal sent by the base station, determining a class value corresponding to the at least one reference signal, and performing beam measurement for the at least one reference signal to obtain a measurement result, wherein the class value is correlated with a beam bandwidth of the reference signal; and determining, based on at least one of the measurement result of the reference signal or the configuration information, a class value of an anchor reference signal, and performing at least one of the beam measurement or data reporting by anchoring on an anchor reference signal corresponding to the class value of the anchor reference signal.
