Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If reference signals are transmitted at constant power, then transmission simplicity is maintained, but signal reception accuracy deteriorates under high interference conditions
Solution Approach 1:
The patent implements dynamic reference signal power adjustment based on detected interference levels. The system transitions from constant power transmission to adaptive power control, where the reference signal power is modified in response to measured radio interference conditions, thereby maintaining reception accuracy without sacrificing operational simplicity
Solution Approach 2:
The system employs feedback mechanisms by monitoring radio interference levels and using this information to adjust reference signal power. The wireless communication device measures interference, determines appropriate power adjustments, and applies these adjustments to subsequent reference signal transmissions, creating a closed-loop control system that resolves the contradiction between transmission simplicity and reception accuracy
2Measurement precision
If reference signal power is increased to overcome interference, then signal reception accuracy improves, but energy consumption increases
Solution Approach 1:
The patent changes the power parameter of reference signals adaptively based on interference conditions rather than using a fixed high power level. By adjusting the power parameter dynamically - increasing it only when interference is detected and maintaining lower levels when conditions are good - the system achieves accurate signal reception while minimizing unnecessary energy consumption
Solution Approach 2:
The system implements dynamic power control that adjusts reference signal transmission power in real-time based on measured interference levels. This dynamic approach allows the system to consume more energy only when necessary for overcoming interference, rather than continuously operating at high power levels, thus resolving the contradiction between reception accuracy and energy efficiency
3Productivity
If parallel wireless access nodes are deployed to serve more users, then service capacity increases, but radio interference increases
Solution Approach 1:
The patent uses feedback from interference measurements to control reference signal power transmission. By monitoring the interference environment created by multiple parallel access nodes and adjusting power levels accordingly, the system maintains service capacity while mitigating the harmful interference effects through adaptive power control
Solution Approach 2:
The system changes transmission power parameters dynamically in response to interference conditions generated by parallel node operation. This allows the network to maintain high service capacity through multiple access nodes while adjusting power parameters to keep interference at acceptable levels, resolving the contradiction between productivity and harmful factors
