Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual configuration is used to ensure compatibility between radio frequency unit and distributed unit supporting multiple signal processing manners, then communication reliability is improved, but labor and material resource consumption increases
Solution Approach 1:
The radio frequency unit and distributed unit automatically determine compatible signal processing manners through capability exchange and negotiation mechanisms. The radio frequency unit sends first information indicating supported signal processing manners, the distributed unit receives this information and determines compatible manners, then sends second information back. This self-service automation eliminates manual configuration while ensuring communication reliability through capability matching.
Solution Approach 2:
The system performs preliminary capability advertisement where the radio frequency unit sends first information about supported signal processing manners before actual communication occurs. The distributed unit processes this information in advance to determine compatibility, preparing the communication parameters beforehand to avoid manual configuration during operation.
2Stability of the object's composition
If manual configuration is used to ensure compatibility between radio frequency unit and distributed unit, then communication stability is improved, but operational complexity increases
Solution Approach 1:
The radio frequency unit and distributed unit autonomously perform capability exchange and compatibility determination through standardized message exchange. The radio frequency unit advertises supported signal processing manners via first information, the distributed unit processes this information and responds with second information indicating determined compatible manners, eliminating manual configuration operations while maintaining communication stability.
Solution Approach 2:
The system employs a universal capability exchange mechanism that works across different signal processing manners and unit configurations. The first information and second information message structure provides a multi-functional framework that handles various signal processing compatibility scenarios through a standardized automated process, reducing operational complexity while ensuring stable communication.
3Adaptability or versatility
If automated indication-based configuration is implemented, then operational flexibility is improved, but device complexity increases
Solution Approach 1:
The radio frequency unit performs preliminary capability advertisement by sending first information indicating supported signal processing manners before communication establishment. The distributed unit processes this information in advance to determine compatibility and prepares appropriate configuration parameters, enabling flexible automated adaptation without requiring complex real-time decision-making logic during operation.
Solution Approach 2:
The distributed unit sends second information back to the radio frequency unit, providing feedback about the determined compatible signal processing manners. This feedback mechanism enables the radio frequency unit to adjust its signal processing approach based on the distributed unit's capabilities, achieving operational flexibility through a relatively simple bidirectional information exchange protocol.

AI summary
This application provides a communication method and a related apparatus to enable communication on a link between a radio frequency unit and a distributed unit in a target signal processing manner based on receipt of first information. Embodiments of this application enable communication between the radio frequency unit and the distributed unit without manual configuration, thereby reducing physical labor and use of material resources, and improving flexibility of communication. In the method, first information is received, where the first information indicates a target signal processing manner in N signal processing manners, N is an integer greater than 1, and the N signal processing manners include a downlink signal processing manner or an uplink signal processing manner. Communication on a link between a radio frequency unit and a distributed unit is then performed in the target signal processing manner.
