Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If distributed antenna systems are deployed to improve coverage and capacity, then network performance is enhanced, but interference management becomes more complex and positioning accuracy deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where the wireless communication device reports antenna configuration information to the network entity. This feedback loop enables the network to track and compensate for antenna changes, maintaining positioning accuracy despite the complexity introduced by distributed antenna deployments.
Solution Approach 2:
The patent dynamically adjusts PRS configuration parameters based on antenna configuration changes. When antenna configurations change, the system modifies measurement parameters and reporting requirements to maintain positioning accuracy, resolving the contradiction between network performance enhancement and measurement precision.
2Reliability
If antenna configurations are dynamically changed to optimize signal quality, then positioning performance is improved, but system complexity increases and measurement errors occur
Solution Approach 1:
The system uses feedback mechanisms where the wireless communication device notifies the network entity of antenna configuration changes. This enables automatic adaptation of PRS measurements and reporting, improving positioning reliability while managing system complexity through automated responses rather than manual configuration.
Solution Approach 2:
The patent performs preliminary actions by pre-configuring the device to monitor and report antenna configuration changes. This preparation allows the system to respond efficiently to antenna changes without increasing operational complexity, as the measurement and reporting procedures are already in place and activated when needed.
3Measurement precision
If PRS measurements are performed with multiple antenna configurations, then positioning accuracy is improved, but measurement time increases and throughput decreases
Solution Approach 1:
The patent implements dynamic measurement procedures where the system adapts the number and type of measurements based on current antenna configurations and network conditions. This dynamic approach maintains positioning accuracy when needed while reducing measurement time and increasing throughput during stable conditions.
Solution Approach 2:
The system dynamically changes measurement parameters such as the number of PRS measurements, measurement frequency, and reporting granularity based on antenna configuration stability and network load. This parameter adaptation resolves the contradiction by performing detailed measurements only when necessary, thereby maintaining accuracy without significantly impacting throughput.
