Solution Overview
Problem
Current wireless communication networks face challenges in efficiently managing positioning of wireless devices, particularly in supporting multiple Positioning Reference Signal (PRS) configurations, which affects positioning accuracy and resource utilization.
Innovation Solution
The solution involves wireless devices sending capability information about supporting multiple PRS configurations to network nodes, which then provide assistance data for configuring and using these configurations, allowing network nodes to determine the relevance and accuracy of positioning measurements based on the scope of usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple PRS configurations are provided to improve positioning accuracy, then positioning measurement precision is improved, but network resource consumption increases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the set of PRS configurations based on wireless device capabilities. The network node receives capability information from the wireless device and selectively provides only the relevant PRS configurations needed for accurate positioning, rather than providing all possible configurations. This optimizes the balance between positioning precision and network resource consumption.
2Adaptability or versatility
If all PRS configurations are provided to ensure comprehensive positioning support, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent extracts only the necessary PRS configurations from the complete set based on wireless device capabilities. The network node filters and selects only the relevant configurations needed for positioning, excluding unnecessary ones. This reduces the complexity burden on the wireless device while maintaining adequate positioning adaptability.
Solution Approach 2:
The system dynamically changes the parameter of PRS configuration selection based on the wireless device's capability information. By adapting the configuration set to match the device's capabilities, the system achieves versatility without overwhelming the device with all possible configurations.
3Productivity
If capability information exchange is implemented to optimize positioning, then resource utilization is improved, but signaling overhead increases
Solution Approach 1:
The patent implements a feedback mechanism where the wireless device provides capability information to the network node, which then uses this feedback to optimize PRS configuration selection. This feedback loop enables efficient resource utilization by tailoring the configuration set to actual device needs, minimizing unnecessary signaling and resource consumption.
