Engineering Contradiction Analysis
1Productivity
If the secondary system utilizes spectrum resources dynamically, then spectrum utilization efficiency is improved, but interference to the primary system increases
Solution Approach 1:
The patent implements a feedback mechanism where the secondary system monitors the primary system's signal strength and adjusts its transmission power accordingly. When the primary system's signal is detected above a threshold, the secondary system reduces or stops transmission to avoid interference. This feedback loop enables dynamic adaptation to primary system activity, allowing the secondary system to utilize spectrum resources efficiently while preventing harmful interference to the licensed primary system.
Solution Approach 2:
The patent employs dynamic spectrum access where the secondary system's transmission parameters (power, timing, frequency) are continuously adjusted based on real-time detection of primary system signals. This dynamic behavior allows the secondary system to exploit available spectrum opportunities when the primary system is not transmitting, while automatically retreating when primary system activity is detected, thus resolving the contradiction between utilization efficiency and interference prevention.
2Productivity
If multiple secondary systems share the same spectrum resources, then spectrum utilization efficiency is improved, but aggregated interference to the primary system increases
Solution Approach 1:
The patent applies local quality by allowing different secondary systems to transmit with different power levels based on their specific locations and interference conditions. Each secondary system independently adjusts its transmission parameters according to local interference measurements, enabling multiple systems to coexist in the same spectrum resources while controlling their individual contributions to aggregated interference. This localized adaptation prevents any single secondary system from causing excessive interference to the primary system.
