Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If cell change is performed during positioning measurement, then mobility and network flexibility are improved, but measurement accuracy and continuity are degraded
Solution Approach 1:
The network node pre-configures measurement parameters and algorithms in the user equipment before cell changes occur. This includes setting up measurement bandwidth configurations and time duration parameters that will be automatically applied when cell changes are detected, ensuring measurement continuity without interruption.
Solution Approach 2:
The patent dynamically adjusts measurement parameters such as measurement bandwidth and time duration based on the specific cell change scenario. By modifying these parameters adaptively, the system maintains measurement accuracy during transitions while minimizing the impact on mobility performance.
2Measurement precision
If measurement time and bandwidth are increased to maintain accuracy during cell changes, then positioning precision is improved, but resource consumption and system complexity increase
Solution Approach 1:
The user equipment is equipped with pre-configured measurement algorithms and parameters that enable it to autonomously adjust its measurement behavior during cell changes. The device self-manages the measurement process by detecting cell changes and applying appropriate measurement configurations without requiring complex real-time network control, thereby reducing system complexity while maintaining accuracy.
Solution Approach 2:
The measurement configuration is made dynamic rather than static. The system automatically adapts measurement time and bandwidth parameters based on the detected cell change conditions, allowing flexibility in resource allocation while maintaining measurement precision without requiring complex manual configuration.
3Stability of the object's composition
If cell change information is recorded and processed, then measurement continuity is improved, but information processing load and system overhead increase
Solution Approach 1:
The patent extracts and processes only the essential cell change information parameters that are directly relevant to maintaining measurement continuity. By filtering and selecting only the critical information elements (such as cell identity, change timing, and bandwidth associations), the system reduces the overall information processing load while still ensuring measurement stability.
4Measurement precision
If measurement bandwidth is altered based on cell bandwidths, then measurement accuracy is maintained, but device complexity and computational requirements increase
Solution Approach 1:
The measurement bandwidth parameter is dynamically changed based on the bandwidth characteristics of the involved cells. The user equipment adjusts its measurement bandwidth to match the cell bandwidth, which maintains measurement accuracy while avoiding the energy consumption associated with processing unnecessary bandwidth data.
