Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If signals are configured with spatial relations associated with specific paths, then positioning accuracy is improved, but device complexity increases
Solution Approach 1:
The patent segments the spatial relation configuration into multiple independent parameters including path type indication, reference signal association, and measurement configuration. This allows the complex positioning task to be divided into manageable configuration elements that can be independently optimized and processed.
Solution Approach 2:
The patent introduces a new dimension of path-based spatial relation configuration beyond traditional signal association. By adding path type indication and multi-path measurement capabilities, the system transitions from two-dimensional signal-space configuration to three-dimensional space-path-signal configuration, enabling more precise positioning.
2Measurement precision
If transmission paths are optimized to reduce obstacles, then measurement precision is improved, but system complexity increases
Solution Approach 1:
The patent performs preliminary path identification and classification before signal transmission. By pre-configuring path types and associating reference signals with specific paths, the system prepares the optimal transmission routes in advance, avoiding real-time path selection complexity during actual positioning operations.
Solution Approach 2:
The patent introduces path type indication as an intermediary element that mediates between the physical transmission environment and the signal configuration. This intermediary abstracts the complex path management into standardized path types, simplifying the control while maintaining measurement precision.

AI summary
In the field of positioning technologies, a communication method, an apparatus, a storage medium, and a computer program product are provided, and are used to configure a signal used for positioning, to improve positioning precision. In this application, a first apparatus receives first configuration information and second configuration information of a first signal, and sends the first signal based on the first configuration information and the second configuration information. The first configuration information indicates that the first signal is associated with a spatial relation of a target signal. The second configuration information indicates that the first signal is associated with a spatial relation of a path of the target signal. In this way, a beam of the first signal may face a direction of the path of the target signal.
