D2D Energy-Saving Configuration for Adaptive Resource Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Device-to-Device (D2D) communication, user equipment (UE) continuously monitors data receiving channels for resource selection, leading to significant power consumption due to indeterminate data transmission times, with existing NR sidelink communication systems neglecting energy-saving considerations.
Innovation Solution
A method and apparatus for energy-saving configuration, where a first communication node receives UE energy-saving information from a second node and sends configuration information to adjust resource pool measurements and selection modes, reducing power consumption by implementing flexible energy-saving strategies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If user equipment continuously monitors data receiving channels for resource selection, then resource selection accuracy is improved, but power consumption increases significantly
Solution Approach 1:
The patent implements dynamic monitoring strategies where UE adjusts its monitoring behavior based on current communication conditions. The network can configure different monitoring modes (e.g., continuous monitoring, periodic monitoring, or on-demand monitoring) depending on traffic patterns, channel conditions, and QoS requirements. This dynamic approach allows the system to maintain resource selection accuracy when needed while reducing power consumption during low-activity periods.
Solution Approach 2:
The patent changes the monitoring parameters (such as monitoring interval, monitoring duration, and resource pool configuration) based on UE capability information and current communication status. By adjusting these parameters dynamically, the system can optimize the balance between measurement precision and energy consumption, allowing UE to monitor less frequently or for shorter durations when high accuracy is not critical, thereby saving power.
2Reliability
If user equipment performs continuous monitoring to assist transmission resource selection, then communication reliability is improved, but energy efficiency deteriorates
Solution Approach 1:
The patent performs preliminary actions by having the network configure monitoring parameters and resource pools in advance based on UE capability information. This allows UE to prepare for potential communication needs without continuous active monitoring. The pre-configuration includes setting up resource pools, monitoring occasions, and measurement parameters that UE can use when needed, reducing the need for continuous monitoring while maintaining reliability.
Solution Approach 2:
The patent implements feedback mechanisms where the network receives UE capability information and communication status reports, then adjusts monitoring configurations accordingly. This feedback loop allows the system to optimize the balance between reliability and energy efficiency by adapting monitoring intensity to actual communication needs, ensuring reliability is maintained only when necessary while minimizing energy consumption during normal operation.
