Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If periodic PRS transmission is used, then positioning continuity is maintained, but resource utilization deteriorates
Solution Approach 1:
The patent applies periodic action by implementing aperiodic PRS transmission that can be triggered periodically based on positioning needs. The network can configure the terminal to transmit PRS at specific intervals or upon trigger events, combining the reliability of periodic transmission with the efficiency of on-demand transmission, thereby resolving the contradiction between positioning continuity and resource utilization.
Solution Approach 2:
The patent implements dynamics by making the PRS transmission schedule flexible and adaptive. Instead of fixed periodic transmission, the system can dynamically adjust transmission timing based on terminal movement status, network conditions, and positioning requirements. This dynamic approach allows the system to maintain positioning continuity when needed while reducing resource consumption during stable periods.
2Loss of energy
If aperiodic PRS transmission on demand is implemented, then resource utilization improves, but positioning flexibility deteriorates
Solution Approach 1:
The patent applies feedback by implementing a trigger mechanism where the network monitors terminal positioning needs and provides feedback through trigger signals. When positioning is required, the network sends a trigger to activate aperiodic PRS transmission. This feedback loop enables the system to maintain positioning flexibility through on-demand transmission, resolving the contradiction between resource utilization and positioning adaptability.
Solution Approach 2:
The patent implements preliminary action by pre-configuring the terminal with PRS transmission parameters and trigger conditions. The terminal is prepared in advance with the necessary configuration information, so when a positioning event occurs, it can immediately execute the appropriate transmission without delay. This preliminary setup maintains positioning flexibility while avoiding unnecessary resource consumption during non-triggered periods.
3Use of energy by stationary object
If PRS transmission is triggered on demand, then network power consumption decreases, but positioning response time increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring the terminal with all necessary PRS transmission parameters, including timing information and trigger conditions. When a positioning event occurs, the terminal can immediately execute the transmission based on pre-set parameters, minimizing response time. This preliminary configuration resolves the contradiction by enabling rapid on-demand transmission without the delays associated with real-time configuration.
Solution Approach 2:
The patent implements an intermediary mechanism where the network manages PRS trigger signals and transmission coordination. The location management network element acts as an intermediary between positioning requests and actual signal transmission, optimizing the timing and coordination of PRS sends. This intermediary role enables efficient power management while maintaining acceptable positioning response times through intelligent scheduling.
