Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional addressing methods are used for beam positions, then the system is simpler to implement, but the accuracy of beam position scheduling deteriorates
Solution Approach 1:
The patent divides the beam position addressing system into multiple hierarchical levels (first-level information, second-level information, etc.). Each level provides progressively more precise location data, allowing the system to achieve high scheduling accuracy by combining multiple levels of addressing information rather than relying on a single complex addressing scheme.
2Measurement precision
If detailed beam position information is stored in terminals, then scheduling accuracy improves, but storage overhead increases
Solution Approach 1:
The patent extracts and separates different levels of beam position information (first-level, second-level, etc.) so that terminals only need to store and process the necessary portion (e.g., first-level information) while the network device maintains the complete hierarchical structure. This reduces terminal storage overhead while preserving scheduling accuracy through multi-level information combination.
3Reliability
If multi-level area division is implemented, then beam position uniqueness is ensured, but system complexity increases
Solution Approach 1:
The patent implements a nested hierarchical structure where second-level areas are contained within first-level areas, third-level within second-level, and so on. Each level of addressing information corresponds to a nested area division, ensuring that the combination of multiple levels uniquely identifies beam positions while organizing the complexity in a structured, manageable way.

AI summary
This application pertains to the field of communication technologies, and provides a communication method and apparatus, to ensure accuracy of beam position scheduling by accurately addressing each beam position. In the method, a terminal sends first beam position information that is level information, so that the first beam position information can indicate a unique beam position. In this way, each beam position is accurately addressed, to ensure that a first network device can accurately schedule the beam position.
