Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for efficient power management in 5G wireless communication systems, particularly in mitigating power consumption through sophisticated discontinuous reception and transmission techniques, is not adequately addressed by existing technologies.
Innovation Solution
The method involves transmitting UECapabilityInformation to the GNB, receiving RRCReconfiguration, performing DTX operations based on specific configurations, and synchronizing DTX cycles with DRX cycles, utilizing parameters like dtx2OffsetDelta to determine the starting points of DTX and DRX cycles, thereby optimizing power usage in 5G systems.

Engineering Contradiction Analysis
1Use of energy by moving object
If discontinuous reception and transmission techniques are implemented in 5G systems, then power consumption is reduced, but system complexity increases
Solution Approach 1:
The patent segments the DRX and DTX operations into distinct configurable cycles with separate parameters (drx-OnDuration, dtx-OnDuration, drx-SlotOffset, dtx-SlotOffset). This allows independent control of reception and transmission discontinuous periods, enabling fine-grained power management while maintaining manageable system complexity through modular configuration.
Solution Approach 2:
The patent introduces dynamic configuration mechanisms where the gNB can adjust DRX and DTX parameters based on traffic conditions and UE power consumption requirements. The network can modify cycle lengths, on-duration periods, and offset values to adapt to changing conditions, optimizing the balance between power savings and system responsiveness.
2Use of energy by moving object
If DRX and DTX cycles are synchronized using dtx2OffsetDelta, then power efficiency is improved, but control complexity increases
Solution Approach 1:
The patent introduces dtx2OffsetDelta as an intermediary parameter that mediates the synchronization between DRX and DTX cycles. This offset parameter acts as a control variable that aligns the starting points of reception and transmission discontinuous periods, enabling coordinated power saving without requiring complex inter-dependent control logic.
Solution Approach 2:
The patent establishes the dtx2OffsetDelta configuration in advance through RRC signaling before actual DRX/DTX operation begins. This preliminary configuration of the offset relationship simplifies subsequent real-time operations by pre-defining the synchronization pattern, reducing the need for complex runtime calculations and control decisions.
