Sidelink UE Message Transmission Feedback Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In dense user equipment (UE) environments, existing wireless communication systems face challenges in ensuring user safety while minimizing unnecessary redundant message transmission and power consumption, particularly in sidelink communication scenarios like V2X, where communication traffic and power consumption are high due to frequent message transmissions.
Innovation Solution
A method and apparatus for determining whether to transmit a message based on clustering, where a UE obtains state information, receives a first message, and decides to transmit a second message based on geographic area and collision risk information included in the first message, optimizing transmission to avoid redundant messages and conserve power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a UE transmits messages frequently in dense environments to ensure user safety, then reliability is improved, but power consumption increases
Solution Approach 1:
The UE receives feedback information from the network indicating whether it should transmit a second message, and makes transmission decisions based on this feedback. This feedback mechanism allows the system to optimize message transmission based on actual network conditions and safety requirements, reducing unnecessary transmissions while maintaining reliability.
Solution Approach 2:
The transmission behavior is dynamically adjusted by changing the parameter of message transmission based on received feedback information. When feedback indicates that a second message should be transmitted, the UE transmits; otherwise, it refrains from transmission. This dynamic parameter adjustment optimizes the balance between reliability and power consumption.
2Reliability
If a UE transmits messages frequently in dense environments to ensure user safety, then reliability is improved, but communication traffic increases
Solution Approach 1:
The UE utilizes feedback information from the network to determine whether second message transmission is necessary. This feedback-driven approach reduces redundant message transmissions in dense environments while ensuring that safety-critical messages are transmitted, thereby optimizing the balance between reliability and communication traffic.
3Reliability
If a UE transmits messages frequently in dense environments to ensure user safety, then reliability is improved, but unnecessary redundant message transmission increases
Solution Approach 1:
The network provides feedback information to the UE indicating whether a second message should be transmitted. The UE makes transmission decisions based on this feedback, which eliminates unnecessary redundant transmissions while maintaining reliability for safety-critical communications. This feedback mechanism optimizes resource utilization by preventing duplicate message transmissions.
