Client Device Rest Period for RedCap Power Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Reduced Capability (RedCap) new radio (NR) devices, particularly those used in IoT applications like industrial sensors, face challenges in energy efficiency due to frequent uplink-centric data transmissions, which can deplete battery life quickly.
Innovation Solution
A client device is configured to transmit a rest period start indication to a network node device, indicating a period during which it will not respond to discontinuous reception paging, thereby reducing power consumption by ceasing such paging activities during this time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If discontinuous reception paging is performed continuously, then the device can respond to network communications, but power consumption increases and battery life decreases
Solution Approach 1:
The patent implements periodic action by introducing rest periods where the device temporarily suspends DRX paging monitoring. The device alternates between active paging periods and rest periods, reducing power consumption while maintaining periodic connectivity. This is achieved by configuring rest period parameters and transitioning to a non-monitoring state during rest periods.
Solution Approach 2:
The patent applies dynamics by making the DRX paging behavior adaptive rather than static. The device dynamically adjusts its paging monitoring based on configured rest period parameters, transitioning between active and inactive states. This dynamic adjustment allows the device to optimize power consumption while maintaining necessary network responsiveness.
2Reliability
If discontinuous reception paging is performed continuously, then the device maintains network connectivity, but battery life is reduced
Solution Approach 1:
The patent extends battery life through periodic action by implementing rest periods within the DRX cycle. The device periodically suspends paging monitoring for configured durations, allowing battery recharging while maintaining periodic network connectivity. This creates a rhythm of active and inactive periods that preserves battery life.
Solution Approach 2:
The patent applies preliminary action by pre-configuring rest period parameters before entering the rest state. The device prepares the rest period configuration in advance, including duration and transition parameters, ensuring smooth transitions between active and inactive states while maintaining network connectivity requirements.
3Use of energy by moving object
If the device enters rest period to save power, then power consumption is reduced, but response time to paging increases
Solution Approach 1:
The patent addresses the response time issue through dynamics by implementing configurable rest period parameters that allow flexible adjustment of the inactive duration. The device can dynamically transition back to active paging monitoring after rest periods, and the network can be configured with appropriate rest period lengths to balance power savings with acceptable response times.
Solution Approach 2:
The patent applies parameter changes by configuring rest period duration and transition parameters to optimize the balance between power consumption and response time. By adjusting these parameters, the system can achieve significant power savings while ensuring that the device returns to active monitoring within acceptable time frames for the specific application requirements.
