Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional measurement gap configuration mechanism is used, then the measurement gap is configured as 6 ms, but the UE cannot successfully receive signals from neighboring cells with different scanning periods
Solution Approach 1:
The measurement gap configuration is made dynamic by adapting it to the specific scanning periods of neighboring cells. Instead of using a fixed 6ms gap, the system determines measurement gaps based on the actual scanning periods obtained from neighboring cell information, allowing the gap duration to vary according to the specific measurement scenario and ensuring reliable signal reception for different cell types.
Solution Approach 2:
The measurement parameters (gap duration, periodicity) are changed based on the scanning periods of neighboring cells. The system obtains scanning period information from neighboring cells and uses this to adjust the measurement gap configuration, transforming the static parameter into a variable one that adapts to different network conditions and cell characteristics.
2Reliability
If the measurement gap is increased to ensure successful signal reception from all neighboring cells, then signal reception reliability improves, but system overhead increases
Solution Approach 1:
Different measurement gap configurations are applied to different neighboring cells based on their specific scanning periods. Instead of using a uniform large gap for all cells, the system tailors the measurement gap duration to match each cell's scanning characteristics, ensuring reliable reception for each cell while minimizing the overall measurement time and reducing system overhead.
Solution Approach 2:
The system performs preliminary acquisition of neighboring cell information, including scanning period data, before configuring the measurement gaps. This advance preparation allows the network to optimize the measurement gap configuration in advance, ensuring that the gaps are sufficiently long for reliable signal detection while avoiding unnecessarily long gaps that would increase overhead.
