Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in optimizing power reduction during discontinuous reception (DRX) in user equipment, as current methods employ a single power optimization technique for varying DRX gap lengths, which may not be suitable for all durations, leading to inefficient power conservation.
Innovation Solution
User equipment (UE) dynamically selects a power reduction technique based on calculated DRX gap length from a plurality of techniques, applying the appropriate method to the receiver circuit during the DRX gap to optimize power conservation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single power optimization technique is used for all DRX gap lengths, then device complexity is reduced, but power conservation efficiency deteriorates
Solution Approach 1:
The patent implements dynamic power optimization by selecting different power reduction techniques based on the calculated DRX gap length. The system transitions from a static single-technique approach to a dynamic multi-technique selection mechanism, where the processing circuit dynamically determines the appropriate power reduction technique (first, second, or third) based on real-time DRX gap length calculations, thereby optimizing power conservation without excessive complexity
Solution Approach 2:
The patent changes the parameter of power reduction technique selection based on the DRX gap length parameter. Different power reduction techniques are applied according to different DRX gap length ranges, allowing the system to adapt power consumption to varying operational conditions rather than using a fixed approach for all scenarios
2Use of energy by moving object
If multiple power reduction techniques are implemented for different DRX gap lengths, then power conservation efficiency is improved, but device complexity increases
Solution Approach 1:
The patent segments the power optimization approach by dividing different DRX gap length ranges into distinct categories, each associated with a specific power reduction technique. The processing circuit calculates the DRX gap length and selects from segmented options (first power reduction technique for shorter gaps, second technique for medium gaps, third technique for longer gaps), making the complexity manageable through structured segmentation rather than a monolithic complex system
Solution Approach 2:
The patent applies local quality by tailoring the power reduction technique to the specific local condition of DRX gap length. Each DRX gap length range receives a customized power optimization approach suited to its characteristics, rather than applying a uniform technique everywhere, thereby achieving optimal power conservation for each operational scenario

AI summary
User Equipments (UEs) are adapted to facilitate power conservation by dynamic selection of power reduction techniques during discontinuous reception (DRX), where the power reduction techniques are selected based on a DRX gap length. UEs may be adapted to calculate a DRX gap length, and identify a power reduction technique associated with the determined DRX gap length. The identified power reduction technique may be applied to a receiver circuit during the DRX gap. Other aspects, embodiments, and features are also included.
