Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If network nodes operate in full duplex mode to improve spectral efficiency, then resource allocation efficiency is improved, but interference between uplink and downlink signals increases
Solution Approach 1:
The patent introduces an intermediary mechanism in the form of capability indication messages and configuration signaling between network nodes. These intermediaries enable the exchange of duplex capability information and resource configuration details, allowing nodes to coordinate full duplex operations while managing interference through informed resource allocation decisions.
Solution Approach 2:
The patent implements dynamic resource configuration where network nodes can adjust their operating parameters based on exchanged capability information. The system dynamically adapts resource allocation, timing, and frequency parameters according to the specific duplex capabilities and interference conditions of each node pair, enabling flexible interference management.
2Productivity
If network nodes exchange duplex capability information to optimize resource allocation, then system performance is improved, but signaling overhead increases
Solution Approach 1:
The patent applies preliminary action by having network nodes exchange capability indication information during the setup or reconfiguration phase before actual data transmission begins. This preliminary exchange allows the system to pre-configure resources and establish optimal operation parameters, avoiding the need for continuous signaling during active communication.
Solution Approach 2:
The patent utilizes parameter changes by encoding duplex capability information and configuration parameters in a structured manner that can be efficiently processed. The system changes operational parameters such as timing advance, frequency allocation, and power control based on the exchanged capability information, achieving optimization with minimal additional signaling.
3Productivity
If network nodes configure resources based on duplex capability indications, then communication efficiency is improved, but complexity in resource management increases
Solution Approach 1:
The patent applies segmentation by dividing the resource management function into distinct modular components: capability indication generation, capability reception and interpretation, and resource configuration. This segmentation allows each component to handle specific aspects of duplex coordination independently, making the overall complex system more manageable and easier to implement.
Solution Approach 2:
The patent implements feedback mechanisms where network nodes receive capability indications from counterpart nodes and adjust their resource configurations accordingly. This feedback loop enables automatic adaptation to different duplex capabilities, reducing the need for complex manual configuration and simplifying resource management through automated responses to capability information.
