Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently coordinating sidelink parameters for user equipment (UE) in Mode 2 sidelink communication, leading to interference and reduced reliability, especially in dynamic environments like moving vehicles.
Innovation Solution
A method where user equipment (UE) receives a configuration from a cloud-based platform for Mode 2 sidelink measurement reporting, transmitting reports that allow the platform to coordinate optimal sidelink parameters across multiple UEs in a geographic area, using machine learning to determine parameters such as MCS, HARQ retransmissions, and sidelink transmit power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UE operates autonomously in Mode 2 sidelink without cloud coordination, then device complexity is reduced and ease of operation is improved, but communication reliability deteriorates due to interference and suboptimal parameter selection
Solution Approach 1:
The patent introduces a cloud-based platform as an intermediary between multiple UEs to coordinate sidelink parameters. The platform receives measurement reports from UEs, processes this information centrally, and returns coordinated configuration parameters. This mediator approach enables reliable coordination without requiring direct complex interactions between individual UEs, resolving the contradiction by centralizing intelligence rather than distributing complex decision-making logic.
Solution Approach 2:
The patent implements a feedback mechanism where UEs transmit measurement reports to the cloud platform, which then returns configured parameters based on the collected measurements. This closed-loop feedback system enables the platform to optimize sidelink parameters dynamically based on actual channel conditions, improving communication reliability while keeping UE complexity low since the feedback processing is performed centrally.
2Reliability
If cloud-based platform coordinates sidelink parameters for multiple UEs, then communication reliability and efficiency are improved, but loss of time increases due to reporting and coordination delays
Solution Approach 1:
The patent applies preliminary action by having UEs configure and transmit measurement reports in advance before actual sidelink communication begins. The cloud platform processes these reports and returns coordinated parameters beforehand, allowing UEs to use pre-optimized parameters for subsequent communications. This advance preparation reduces real-time coordination delays and improves overall system efficiency.
Solution Approach 2:
The patent implements periodic measurement reporting where UEs transmit measurement reports at scheduled intervals rather than continuously. This periodic action reduces the time overhead associated with constant communication while still providing the cloud platform with sufficient information to coordinate parameters effectively. The periodic reporting mechanism balances coordination accuracy with time efficiency.
