Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multi-antenna-panel scenarios are used in vehicle sidelink communication, then positioning information quantity increases, but communication solution completeness deteriorates
Solution Approach 1:
The patent segments the positioning information reporting by introducing different types of reference points (first reference point for measurement value, second reference point for resource identification) and corresponding information fields. This segmentation allows the system to handle multi-antenna-panel scenarios by dividing the complex positioning data into structured, manageable components that can be processed independently.
Solution Approach 2:
The patent adds a new dimension to the communication protocol by introducing reference point information fields that include position coordinates and identification data. This dimensional expansion transforms the positioning information from simple measurement values into multi-dimensional data structures that encompass spatial, temporal, and identification attributes.
2Measurement precision
If reference point information is reported along with measurement values, then positioning accuracy improves, but communication overhead increases
Solution Approach 1:
The patent extracts only the essential reference point information (position coordinates and identification) needed for positioning accuracy, rather than transmitting complete antenna panel configuration data. This extraction principle reduces communication overhead by including only the minimum necessary information while maintaining positioning precision.
Solution Approach 2:
The patent applies local quality by providing detailed reference point information only where needed for positioning measurements, rather than uniformly increasing information transmission across all communication channels. The reference point data is localized to specific measurement contexts, optimizing the balance between accuracy and overhead.

AI summary
The present disclosure provides a communication method and apparatus, including: receiving, by a first device, a first resource sent by a second device; performing measurement on the first resource to obtain a measurement value; sending the measurement value and related information of a first reference point corresponding to the measurement value to the second device or a third device. That is, when sending the measurement value to the second device or the third device, the first device concurrently sends the related information of the first reference point to the second device or the third device. The present disclosure can improve the accuracy and robustness of positioning.
