Sidelink DRX Partial Sensing for Power-Aware Resource Pool Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems, such as 5G NR, face challenges in optimizing power consumption and resource allocation for sidelink communication, particularly in scenarios involving discontinuous reception (DRX) mechanisms, which can lead to inefficient power usage and suboptimal resource utilization.
Innovation Solution
Implementing partial sensing under sidelink DRX mechanisms, where UEs receive resource pool configurations with partial sensing indications to determine whether to perform sensing during inactive times, allowing for selective power-saving strategies based on specific SL transmission resource pools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If full sensing is performed continuously in SL-DRX inactive time, then resource allocation reliability is improved, but power consumption increases
Solution Approach 1:
The patent applies partial sensing by performing sensing operations only on selected resource pools rather than all resource pools during SL-DRX inactive time. The UE determines which resource pools require sensing based on configuration parameters and performs partial sensing operations, thereby reducing power consumption while maintaining adequate resource allocation reliability for critical communications.
Solution Approach 2:
The patent implements different sensing strategies for different resource pools based on their specific requirements. Some resource pools are configured for full sensing while others use partial or no sensing, allowing the system to optimize power consumption locally for each resource pool while maintaining overall reliability through selective sensing approaches.
2Use of energy by moving object
If partial sensing is performed selectively on some resource pools, then power consumption is reduced, but resource utilization efficiency may worsen
Solution Approach 1:
The patent incorporates feedback mechanisms where the UE monitors resource pool conditions and adjusts sensing performance accordingly. Based on sensed channel conditions, traffic patterns, and resource pool status, the UE can dynamically adapt its sensing behavior to maintain resource utilization efficiency while managing power consumption through intelligent feedback-driven decisions.
Solution Approach 2:
The patent enables dynamic sensing performance adjustment where the UE can switch between full sensing, partial sensing, and no sensing modes based on current operational conditions. This dynamic approach allows the system to optimize the balance between power consumption and resource utilization efficiency in real-time according to traffic demands and channel conditions.

AI summary
A method performed by a user equipment (UE) is provided. In the method, one or more first resource pool configurations for one or more sidelink transmission resource pools are received. Each first resource pool configuration includes a partial sensing indication of whether to perform partial sensing on a corresponding sidelink transmission resource pool in a Sidelink Discontinuous Reception (SL-DRX) inactive time. The SL-DRX inactive time is determined based on a set of SL-DRX configurations stored in the UE. In the method, the partial sensing is performed, based on the partial sensing indication of each first resource pool configuration, on the corresponding sidelink transmission resource pool while the UE is implementing sidelink packet transmission.
