Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless devices perform blind estimation of interference characteristics without standardized signaling, then interference mitigation can be attempted, but device complexity and battery consumption increase while performance is reduced
Solution Approach 1:
The network node performs preliminary characterization of interfering signals and proactively provides this information to wireless devices through standardized signaling. This preliminary action eliminates the need for devices to perform complex blind estimation, directly resolving the contradiction by improving performance while reducing device complexity
Solution Approach 2:
The network node acts as an intermediary that characterizes interfering signals and communicates this information to wireless devices. This intermediary approach enables devices to achieve accurate interference mitigation without performing complex blind estimation themselves, thus improving performance while reducing device complexity
2Reliability
If wireless devices perform blind estimation of interference characteristics without standardized signaling, then interference mitigation can be attempted, but battery consumption increases
Solution Approach 1:
The network node performs preliminary characterization of interfering signals and provides this information to wireless devices through standardized signaling. This eliminates the need for energy-consuming blind estimation at the device level, directly resolving the contradiction by maintaining performance while reducing battery consumption
Solution Approach 2:
The network node serves itself by characterizing interfering signals and then providing this information to devices, enabling them to perform efficient interference mitigation without excessive energy consumption. This self-service approach resolves the contradiction by improving performance while reducing device energy usage
3Productivity
If additional base stations are deployed to increase system performance, then capacity and user experience improve, but inter-cell interference becomes more pronounced
Solution Approach 1:
The network node characterizes interfering signals from additional base stations and provides this feedback information to wireless devices. This feedback mechanism enables devices to effectively mitigate the increased inter-cell interference resulting from network densification, thus resolving the contradiction by maintaining high system capacity while managing interference
Solution Approach 2:
The network node acts as an intermediary that characterizes interfering signals from multiple base stations and communicates this information to devices. This intermediary approach enables effective interference mitigation in dense networks, resolving the contradiction by maintaining high capacity while reducing the harmful effects of inter-cell interference
