Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional paging techniques are used, then communication coverage is maintained, but power consumption is high and battery life is poor
Solution Approach 1:
The patent applies dynamics by making the quantity of measurement occasions adjustable rather than fixed. The UE dynamically selects the quantity of measurement occasions based on channel conditions, transitioning between different measurement intensities to balance power consumption and communication reliability. This is evident in the adaptive selection mechanism where the UE modifies its measurement behavior according to observed channel quality.
Solution Approach 2:
The patent changes the parameter of measurement occasion quantity based on channel conditions. When channel conditions are good, the UE reduces the quantity of measurement occasions to save power. When channel conditions deteriorate, the UE increases measurement occasions to maintain reliability. This parameter adjustment directly addresses the contradiction between power consumption and communication reliability.
2Adaptability or versatility
If fixed quantity of measurement occasions is used, then device complexity is low, but adaptability to different channel conditions is poor
Solution Approach 1:
The patent implements self-service by enabling the UE to autonomously select the quantity of measurement occasions based on its own observations of channel conditions. The UE monitors channel quality metrics and independently determines the appropriate measurement intensity without requiring complex network coordination or additional signaling, thus achieving adaptability with minimal added complexity.
Solution Approach 2:
The patent uses feedback mechanisms where the UE monitors channel conditions and uses this feedback to adjust the quantity of measurement occasions. The channel quality metrics serve as feedback that drives the adaptive selection process, allowing the system to respond to changing conditions while maintaining a relatively simple overall structure.
3Measurement precision
If high quantity of measurement occasions is used, then beam selection accuracy is improved, but power consumption increases
Solution Approach 1:
The patent changes the parameter of measurement occasion quantity based on channel conditions to resolve the contradiction between measurement precision and power consumption. In good channel conditions, fewer measurement occasions are sufficient for accurate beam selection, reducing power consumption. In poor channel conditions, more measurement occasions are used to maintain accuracy despite higher power consumption.
Solution Approach 2:
The patent applies dynamics by making the measurement occasion quantity flexible and adaptive rather than static. The system dynamically adjusts measurement intensity to match actual channel conditions, ensuring sufficient beam selection accuracy only when necessary, thereby reducing overall power consumption while maintaining measurement precision when required.

AI summary
Methods, systems, and devices for wireless communications are described. A wireless communications system may support adaptive scheduling in idle mode. In some cases, a user equipment (UE) may receive control signaling indicating a first beam sweeping occasion and a first paging occasion within a search time period. The UE may select a first quantity of measurement occasions of the first beam sweeping occasion for monitoring multiple beams. The first quantity of measurement occasions may be based on a channel quality metric observed for a prior beam during a prior beam sweeping occasion. The UE may select a first beam to monitor for a first paging message during the first paging occasion based on respective channel quality metrics observed for multiple beams during the first quantity of measurement occasions. Further, the UE may monitor for the first paging message during the first paging occasion using the first beam.
