Engineering Contradiction Analysis
1Area of stationary object
If relay nodes are deployed in diverse network environments with varying spectrum resources, then network coverage and reachability are improved, but data transmission efficiency deteriorates due to suboptimal path selection
Solution Approach 1:
The patent implements dynamic relay node selection where the terminal device evaluates multiple relay nodes based on current link quality metrics (RSRP, RSRQ, SINR) and selects the optimal relay node for data transmission. This dynamic adaptation to changing network conditions resolves the contradiction by enabling the system to maintain broad network coverage through multiple relay nodes while simultaneously optimizing data transmission efficiency through intelligent selection of the best transmission path.
Solution Approach 2:
The system changes transmission parameters by measuring and comparing link quality indicators (reference signal received power, reference signal received quality, signal-to-interference-plus-noise ratio) for different relay nodes. Based on these parameter evaluations, the terminal device selects the relay node with the optimal parameters, thereby maintaining network coverage while improving data transmission efficiency through parameter-driven optimization.
2Area of stationary object
If multiple relay nodes are used to enhance network reachability, then connection establishment time increases, but network coverage is improved
Solution Approach 1:
The patent implements preliminary action by having the terminal device proactively measure and evaluate link quality parameters of multiple relay nodes before initiating data transmission. The terminal device prepares a list of candidate relay nodes with their associated quality metrics in advance, enabling rapid selection and immediate establishment of the optimal connection when transmission is needed, thus improving network reachability without significantly increasing connection establishment time.
3Area of stationary object
If relay-based connections are used to extend communication range, then transmission paths become more complex, but communication reachability is improved
Solution Approach 1:
The patent extracts the complexity of relay node selection and path management from the terminal device by implementing a standardized measurement and selection mechanism. The terminal device simply measures link quality parameters of available relay nodes and selects the one with the best metrics, while the network infrastructure manages the complex relay-based connection routing. This extraction of complexity resolves the contradiction by enabling extended communication range through relay nodes while keeping the terminal device operations simple and straightforward.
