Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If semi-static channel splitting is used between BBH and BBL, then system stability is maintained, but processing capability utilization on BBL side is insufficient
Solution Approach 1:
The patent implements dynamic channel splitting where the BBH can flexibly adjust the splitting configuration of channels (such as PUSCH, PDSCH, PUCCH, PDCCH) based on real-time processing capability status of the BBL. This allows the system to transition from static to dynamic configuration, enabling the BBL to utilize its processing capability more fully while maintaining system stability through controlled adaptation.
Solution Approach 2:
The patent changes the parameter of channel splitting configuration from fixed to variable. The BBH monitors the processing capability status of the BBL and adjusts channel splitting parameters dynamically. This parameter change enables the system to adapt to varying processing loads and capability states, resolving the contradiction between flexibility and complexity by making the configuration adaptive rather than static.
2Productivity
If BBL processing capability is fully utilized, then wireless communication performance improves, but channel configuration complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the BBH monitors the processing capability status of the BBL and uses this feedback to dynamically adjust channel splitting configurations. The BBH receives processing status information from the BBL, evaluates the current state, and makes informed decisions about resource allocation. This feedback loop enables efficient utilization of BBL processing capability while managing configuration complexity through intelligent, status-driven decision-making.
Solution Approach 2:
The BBL autonomously monitors its own processing capability status and provides this information to the BBH. The system enables self-service by allowing the BBL to self-report its processing state, which the BBH then uses to make configuration decisions. This reduces the need for complex centralized control while still achieving optimal resource utilization.
3Adaptability or versatility
If dynamic channel splitting is implemented, then resource utilization improves, but system complexity increases
Solution Approach 1:
The patent introduces the BBH as an intermediary that manages the dynamic channel splitting process. The BBH acts as a mediator between the BBL's processing capability and the channel configuration requirements. It receives processing status from the BBL, makes configuration decisions, and manages the overall channel splitting process. This intermediary role simplifies the system architecture by centralizing the decision-making logic in the BBH, reducing the complexity burden on the BBL while enabling flexible resource allocation.

AI summary
This application provides example wireless communication methods and apparatuses, which may be applied to a cellular wireless network scenario and a time division duplex (TDD) scenario, and in particular, applied to a sounding reference signal (SRS) channel quality measurement scenario. In one example method, a first communication apparatus determines a second SRS channel processing solution based on a first SRS channel processing result, where the second SRS channel processing solution is used by a second communication apparatus to process an SRS. The second SRS channel processing solution is then sent to the second communication apparatus.
