Engineering Contradiction Analysis
1Productivity
If the UE operates in high power mode to achieve higher throughput and shorter processing timeline, then the data transmission speed and processing efficiency are improved, but the power consumption increases
Solution Approach 1:
The patent implements dynamic mode switching between low power mode and high power mode based on triggering conditions. The UE can transition between different communication configurations (low power, low throughput mode and high power, high throughput mode) to adapt to varying traffic demands, thereby optimizing the balance between power consumption and throughput performance
Solution Approach 2:
The patent changes operational parameters (power mode, throughput level, processing timeline) based on triggering conditions such as packet delay budget, buffer status, and channel quality. By adjusting these parameters dynamically, the system achieves optimal performance while managing power consumption effectively
2Use of energy by moving object
If the UE operates in low power mode with longer processing timeline to reduce energy consumption, then the power usage is optimized, but the data transmission speed decreases
Solution Approach 1:
The system dynamically switches between low power mode and high power mode based on real-time triggering conditions. When traffic demand is low, the UE operates in low power mode to conserve energy; when traffic demand increases or delay constraints are violated, the system transitions to high power mode to restore throughput performance
Solution Approach 2:
The patent uses packet delay budget as a triggering condition to predict when throughput requirements may not be met. By monitoring the packet delay budget and buffer status in advance, the system can proactively switch to high power mode before throughput degradation occurs, ensuring quality of service while minimizing power consumption
3Use of energy by moving object
If the UE frequently transitions between communication modes to adapt to traffic demands, then the power efficiency is improved, but the system complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the UE monitors triggering conditions (packet delay budget, buffer status, channel quality) and automatically adjusts its communication mode accordingly. This closed-loop control simplifies the transition management by providing clear decision criteria, reducing the complexity of mode selection while maintaining optimal power efficiency
Solution Approach 2:
The UE autonomously manages its own mode transitions based on pre-configured triggering conditions without requiring continuous network control. This self-service approach reduces signaling overhead and simplifies the overall system complexity while enabling efficient power management through automatic mode adaptation

AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may operate in different communications profiles associated with different sets of communication parameters that support different threshold throughputs and threshold processing timelines. Use of a set of communication parameters that supports a lower throughput and/or longer timeline may involve lower power usage but longer latency than a set of communication parameters that supports a higher throughput and/or shorter timeline. The UE may transition between use of a higher power, higher throughput mode and a lower power, lower throughput mode based on configured conditions to match different sets of communication parameters to the expected traffic. For example, a network entity may transmit control signaling to a UE that indicates one or more triggering conditions for transition from use of a first mode to a second mode.
