VSEngineering Contradiction Analysis

1Measurement precision

If bandwidth aggregation of positioning reference signals is implemented, then positioning accuracy is improved, but system complexity increases

Engineering Contradiction:
Improvepositioning accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the bandwidth aggregation configuration into multiple independent components: indication information for bandwidth aggregation capability, assistance information for terminal capabilities, and separate configuration parameters for multiple frequency bands and carriers. This segmentation allows the complex bandwidth aggregation function to be managed through modular, independent configuration elements, reducing overall system complexity while maintaining positioning accuracy improvements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements preliminary action by having the terminal pre-send assistance information about its bandwidth aggregation capabilities to the core network device before actual positioning operations. The core network device then pre-generates and sends indication information about available bandwidth aggregation configurations. This preliminary exchange of capability and configuration information allows the system to be optimized in advance, reducing real-time complexity during positioning operations.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If bandwidth aggregation configuration is optimized for positioning, then resource utilization improves, but communication overhead increases

Engineering Contradiction:
Improveresource utilizationVSAvoidcommunication overhead
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent extracts bandwidth aggregation capability information and terminal assistance information as separate, standalone data elements that can be independently configured and transmitted. By extracting these capability indicators from the main positioning protocol, the system can efficiently manage resource utilization through dedicated capability exchange messages, reducing the overhead embedded in core positioning operations while maintaining optimized resource allocation.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent utilizes parameter changes by dynamically adjusting bandwidth aggregation configurations based on terminal capabilities and network conditions. The indication information and assistance information enable flexible parameter modification for different frequency bands and carriers, allowing the system to optimize resource utilization by activating bandwidth aggregation only when and where needed, thereby minimizing unnecessary communication overhead while maintaining high resource efficiency.
