Sidelink Communication Energy Saving State SCI Cancellation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sidelink communication devices face high processing complexity and energy consumption due to the need to blindly detect and measure V2X sidelink control information, particularly in scenarios like vehicle-to-pedestrian communication, where energy efficiency and complexity are critical.
Innovation Solution
Implementing an energy saving state in sidelink communication devices, where conventional operations such as blind detection and demodulation of sidelink control information are cancelled, and a wake-up signal is monitored to exit the energy saving state when necessary, reducing processing complexity and energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sidelink communication devices perform blind detection and sensing operations on V2X sidelink control information, then communication reliability and collision avoidance are improved, but processing complexity and energy consumption increase
Solution Approach 1:
The patent applies dynamics by enabling the sidelink communication device to switch between an active state (for blind detection and sensing) and an energy saving state (for reduced operation). The device dynamically adjusts its operational mode based on communication needs, allowing it to perform reliable V2X communication when necessary while consuming less energy during periods when full functionality is not required.
Solution Approach 2:
The patent implements periodic action through the wake-up signal mechanism that periodically checks whether the device should remain in the energy saving state or transition to the active state. This periodic monitoring allows the device to maintain communication reliability when needed while spending minimal energy on intermittent wake-up checks rather than continuous blind detection operations.
2Reliability
If sidelink communication devices continuously monitor V2X sidelink control information, then collision avoidance is improved, but processing complexity increases
Solution Approach 1:
The patent applies dynamics by enabling the sidelink communication device to switch between an active state (for blind detection and sensing) and an energy saving state (for reduced operation). The device dynamically adjusts its operational mode based on communication needs, allowing it to perform reliable V2X communication when necessary while consuming less energy during periods when full functionality is not required.
Solution Approach 2:
The patent extracts the essential monitoring function by introducing a wake-up signal mechanism that separates the critical function of detecting communication needs from the complex continuous blind detection process. The device only performs complex blind detection operations when the wake-up signal indicates communication is required, thereby extracting and performing only the necessary processing complexity at the appropriate time.
