Engineering Contradiction Analysis
1Measurement precision
If positioning reference signals are transmitted frequently and with high resource allocation to improve positioning accuracy, then positioning accuracy is improved, but energy consumption increases and transmission capacity is reduced
Solution Approach 1:
The patent implements dynamic resource allocation for positioning reference signals based on device conditions. The network node adjusts the resource allocation configuration adaptively according to positioning conditions such as device type, service requirements, and channel state, rather than using fixed resource allocation. This dynamic adjustment optimizes the balance between positioning accuracy and energy consumption by allocating resources only when and where needed.
Solution Approach 2:
The patent changes key parameters of positioning reference signal transmission including resource allocation configuration, periodicity, and bandwidth based on positioning conditions. By adjusting these parameters dynamically according to device type and service requirements, the system achieves optimal positioning accuracy while minimizing energy consumption and maintaining transmission capacity.
2Measurement precision
If positioning reference signals are transmitted with high resource allocation to improve positioning accuracy, then positioning accuracy is improved, but transmission capacity is reduced
Solution Approach 1:
The patent applies different resource allocation configurations to different wireless communication devices based on their specific positioning conditions. Instead of uniform resource allocation across all devices, the system tailors the resource allocation to each device's type, service requirements, and channel state, thereby improving positioning accuracy for each device while minimizing the overall impact on transmission capacity.
Solution Approach 2:
The network node dynamically adjusts resource allocation configurations based on real-time positioning conditions. This dynamic approach allows the system to allocate resources intensively only when high positioning accuracy is required, while maintaining normal transmission capacity during periods when positioning accuracy requirements are lower.
3Reliability
If resource allocation is increased to meet positioning requirements in 5G networks, then positioning performance is improved, but power consumption increases
Solution Approach 1:
The patent adjusts key transmission parameters including resource allocation configuration, signal periodicity, and bandwidth based on positioning conditions and device type. By dynamically changing these parameters, the system ensures reliable positioning performance for devices with high positioning requirements while reducing power consumption for devices with lower requirements, thereby optimizing the overall power-performance tradeoff.
Solution Approach 2:
The patent segments devices into different categories based on positioning conditions such as device type and service requirements. Different resource allocation configurations are assigned to different segments, allowing the system to provide high positioning performance only to devices that require it while minimizing power consumption for other devices.
4Measurement precision
If more system resources are allocated for positioning to fulfill system requirements, then positioning accuracy is improved, but resource efficiency decreases
Solution Approach 1:
The network node implements dynamic resource allocation that adapts to changing positioning conditions. The resource allocation configuration is adjusted in real-time based on device type, service requirements, and channel state, ensuring that resources are allocated efficiently only when and where high positioning accuracy is required, thereby minimizing resource waste while maintaining necessary positioning accuracy.
Solution Approach 2:
The system dynamically changes resource allocation parameters including bandwidth, periodicity, and resource block allocation based on positioning conditions. This parameter adjustment allows the system to achieve high positioning accuracy when needed while minimizing resource consumption during normal operation, thereby improving overall resource efficiency.
