Engineering Contradiction Analysis
1Area of stationary object
If high-powered wireless devices are deployed to boost coverage and enhance throughput, then network coverage and data transmission capacity are improved, but interference with standard-powered devices operating on the same frequency band increases
Solution Approach 1:
The patent implements dynamic adjustment of transmission power for relay devices based on real-time interference conditions. The network node monitors interference levels and dynamically switches relay devices between high-powered and standard-powered modes, allowing the system to adapt transmission characteristics to current network conditions rather than using fixed power levels.
Solution Approach 2:
The patent changes the transmission power parameter of relay devices based on detected interference conditions. When interference is detected, the system transitions relay devices from high-powered transmission mode to standard-powered mode, effectively modifying the power parameter to eliminate harmful interference while maintaining network coverage.
2Length of stationary object
If high-powered transmission mode is used to extend coverage range, then signal reach is improved, but uplink system performance deteriorates due to interference
Solution Approach 1:
The patent implements a feedback mechanism where network nodes monitor uplink signal quality and interference levels, then use this information to control the transmission power of relay devices. The system continuously receives feedback about interference conditions and adjusts relay device power accordingly, creating a closed-loop control system that maintains uplink performance.
Solution Approach 2:
The system dynamically adjusts the transmission characteristics of relay devices based on real-time network conditions. Rather than using static high-powered mode, the relay devices switch between power modes depending on detected interference levels, allowing coverage extension when conditions permit while protecting uplink performance when interference occurs.
3Productivity
If relay devices operate in high-powered mode to enhance throughput, then data transmission capacity is improved, but interference with neighboring access nodes increases
Solution Approach 1:
The patent modifies the transmission power parameter of relay devices based on interference detection. When neighboring access nodes report high interference levels, the system changes the power parameter from high-powered mode to standard-powered mode, directly addressing the harmful interference while allowing high throughput operation when conditions are favorable.
