Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional LTE measurement methods are used, then the system is simple and easy to operate, but multiple-beam measurement reporting cannot be achieved
Solution Approach 1:
The patent segments the measurement process into distinct phases: determining a first quantity of transmission beams for connected state measurement, determining a second quantity of transmission beams for idle state measurement, and selectively applying different measurement configurations based on terminal state. This segmentation allows the system to achieve multiple-beam measurement reporting capability while managing complexity through structured, state-specific procedures.
Solution Approach 2:
The patent implements dynamic adaptation by configuring different measurement parameters based on terminal state (connected or idle). The network side device dynamically adjusts the quantity of transmission beams to be measured and the measurement signal types according to whether the terminal is in connected state or idle state, enabling versatile measurement reporting without requiring a single complex fixed method.
2Measurement precision
If all transmission beams are measured, then measurement completeness is improved, but measurement time and resource consumption increase
Solution Approach 1:
The patent applies partial action by determining a first predetermined quantity of transmission beams (less than all available beams) for measurement in connected state, and a second predetermined quantity of transmission beams for measurement in idle state. This selective measurement of a subset of beams achieves sufficient measurement completeness for network operations while significantly reducing measurement time and terminal resource consumption compared to measuring all beams.
Solution Approach 2:
The patent changes the measurement parameters (quantity of beams to measure, measurement signal type, measurement timing) based on terminal state. In connected state, a first quantity of beams is measured with specific reference signals; in idle state, a second quantity of beams is measured with different reference signals. This parameter adaptation ensures measurement completeness is sufficient for each state's requirements without the overhead of measuring all beams in all states.
