Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system continuously monitors and detects loss of coherence in real-time, then network stability and communication quality are improved, but device complexity and processing overhead increase
Solution Approach 1:
The system performs self-diagnosis by having the UE autonomously detect and report coherence loss conditions to the network entity. The UE monitors its own transmission coherence status and triggers notifications when thresholds are exceeded, eliminating the need for continuous network-side monitoring of each UE's internal state while maintaining reliable detection.
Solution Approach 2:
The system implements a feedback mechanism where the UE monitors transmission coherence and provides feedback to the network entity when loss of coherence is detected. This feedback loop enables the network to respond appropriately (e.g., adjust parameters, reconfigure connections) while the UE handles the continuous monitoring locally, distributing the processing burden.
2Reliability
If the system performs timely adjustments to transmission and reception parameters upon detecting coherence loss, then communication quality is improved, but response time and processing delay increase
Solution Approach 1:
The system pre-configures threshold values for coherence loss detection and prepares response protocols in advance. When the UE detects that coherence metrics exceed pre-set thresholds, it immediately triggers the notification procedure without requiring real-time analysis or decision-making, thereby reducing response delay while maintaining communication quality.
3Measurement precision
If the system implements comprehensive monitoring of transmission parameters, then detection precision is improved, but energy consumption and processing load increase
Solution Approach 1:
The system implements selective monitoring where the UE focuses measurement resources on critical coherence-related parameters (e.g., phase continuity, timing synchronization) rather than all transmission parameters. The UE monitors only those parameters directly related to coherence loss detection, achieving sufficient detection precision while minimizing energy consumption and processing load.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a loss of coherence associated with the UE. The UE may perform at least one adjustment to a transmission parameter or a reception parameter based at least in part on the indication of the loss of coherence. For example, the adjustment to the transmission parameter may include adjusting a transmit power, adjusting a transmit frequency, adapting a transmission time, changing an antenna port, or a combination thereof. Additionally, or alternatively, the adjustment to the reception parameter may include refraining from joint channel estimation across a plurality of slots, adjusting a downscaling parameter or a frequency tuning associated with at least one reception antenna, refraining from blind decoding, or a combination thereof. Numerous other aspects are described.
