Terminal Carrier Selection for Power Reduction in Vehicle Networking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle networking systems, particularly in multi-carrier scenarios, terminal devices face challenges in selecting carriers to reduce power consumption while maintaining effective data transmission and reception.
Innovation Solution
A method where a terminal device receives first information from a network device to determine the enabling status of carriers, allowing it to disable or enable specific carriers for transmission and reception, thereby reducing power consumption by turning off unused carriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the terminal device uses multiple carriers for data transmission in multi-carrier scenarios, then the data transmission capability is improved, but the power consumption increases
Solution Approach 1:
The patent implements dynamic carrier selection by receiving first information from the network device that indicates which carriers should be enabled or disabled. The terminal device dynamically adjusts its carrier usage based on network conditions and traffic requirements, enabling it to use multiple carriers when needed for high data transmission capability while switching to fewer carriers when power consumption needs to be reduced.
2Use of energy by moving object
If the terminal device disables unused carriers to reduce power consumption, then the power usage is optimized, but there is a risk of data loss
Solution Approach 1:
The patent employs feedback mechanisms where the terminal device receives first information from the network device indicating the enabling status of carriers. This feedback loop ensures that carriers are disabled only when the network device determines it is safe to do so, preventing data loss by maintaining synchronization between the terminal's carrier selection and the network's expectations.
Solution Approach 2:
The network device performs preliminary actions by determining and notifying the terminal device about which carriers should be enabled or disabled before the terminal device actually switches carriers. This advance notification ensures that data transmission is properly managed and prevents data loss by coordinating carrier switching with network conditions.
