Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network-controlled repeater applies power amplification and spatial domain filter to relay signals, then the communication quality is improved, but the periodic signals for RRM measurement are disrupted
Solution Approach 1:
The patent segments the signal processing by separating periodic RRM measurement signals from aperiodic data signals. The relay device applies different processing to each type: for periodic signals, it uses fixed power amplification and spatial domain filters without changes, while for aperiodic signals, it dynamically adjusts these parameters. This segmentation allows RRM measurements to remain accurate while still improving communication quality for data transmission.
Solution Approach 2:
The patent implements dynamic control of power amplification and spatial domain filters based on signal type and channel conditions. The relay device determines processing parameters dynamically by identifying whether a signal is periodic (RRM measurement) or aperiodic (data), and adjusts accordingly. This dynamic approach enables optimal performance for both measurement accuracy and communication quality without fixed, disruptive processing.
2Reliability
If the relay device dynamically adjusts power amplification and spatial domain filter, then the communication quality is optimized, but the signal processing complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring fixed power amplification and spatial domain filter values for periodic RRM measurement signals. These fixed parameters are determined in advance and applied consistently, avoiding the need for real-time dynamic adjustment during measurement periods. This reduces processing complexity during critical measurement intervals while maintaining communication quality optimization for data transmission.
Solution Approach 2:
The patent uses dynamic control that adapts to signal characteristics. The relay device identifies whether a signal is periodic or aperiodic and applies appropriate processing accordingly. This dynamic approach optimizes communication quality by matching processing parameters to signal type, while the system manages complexity through intelligent detection and selective processing rather than continuous complex computation.
3Device complexity
If the relay device relays all signals with the same processing, then the device complexity is reduced, but the measurement signals are disrupted
Solution Approach 1:
The patent segments signal processing based on signal periodicity. The relay device identifies periodic signals (RRM measurements) and applies fixed, non-disruptive processing to these specific signal types, while applying dynamic processing to aperiodic data signals. This segmentation ensures measurement accuracy is preserved while still providing optimized processing for data communication, managing complexity through targeted rather than universal processing.
Solution Approach 2:
The patent applies local quality by tailoring processing parameters to specific signal characteristics. For periodic RRM measurement signals, the relay device uses fixed power amplification and spatial domain filters that maintain measurement integrity. For aperiodic data signals, it applies dynamically adjusted parameters optimized for communication quality. This localized approach to quality control ensures measurement accuracy without requiring complex processing for all signals uniformly.
