Virtual UE Scheme for Distributed Antenna Aerodynamic Trade-offs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems face challenges in providing high data rate and quality of service (QoS) for users with high mobility, such as those in vehicles, without compromising vehicle design and aerodynamic performance, and require enhanced network connectivity that is compatible with existing communication standards.
Innovation Solution
The implementation of a virtual UE scheme in a distributed antenna system (DAS) allows for adaptive network connections and high rank communication, enabling high throughput and efficient communication performance without affecting conventional network configurations or vehicle design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large size antenna array is installed outside vehicle to provide high quality service to high speed moving vehicle, then communication quality is improved, but aesthetic problems and aerodynamic problems occur
Solution Approach 1:
The patent divides the vehicle communication system into multiple distributed antenna units positioned at different locations on the vehicle body. Instead of using one large antenna array, multiple smaller antenna elements are segmented and distributed throughout the vehicle structure, allowing each antenna to be aerodynamically friendly while collectively providing high-quality communication coverage.
Solution Approach 2:
The patent transitions from a two-dimensional planar antenna array to a three-dimensional distributed antenna configuration. Antennas are positioned at multiple spatial locations (roof, sides, front, rear) creating a 3D diversity structure that improves communication reliability without requiring large surface area, thus avoiding aerodynamic issues.
2Productivity
If conventional network configurations are used, then compatibility with current systems is maintained, but high throughput and high rank transmission are not achieved
Solution Approach 1:
The patent introduces a virtual UE (User Equipment) as an intermediary layer between the distributed antenna system and the conventional network. The virtual UE aggregates signals from multiple physical antennas and presents a unified interface to the existing network infrastructure, enabling high-throughput transmission without requiring network configuration changes.
Solution Approach 2:
The distributed antenna system is designed to serve multiple functions: it can operate in conventional mode for compatibility and in high-rank transmission mode for enhanced throughput. The system adapts its operation based on network conditions and requirements, providing universal service across different operational modes.

AI summary
A method of accessing a network by using a virtual UE scheme and a UE thereto are disclosed. The method includes performing a first random access procedure for a first DU group including one or more DUs with respect to a base station, performing a second random access procedure for a second DU group with respect to the base station, while maintaining a connection of the first DU group with the base station, and communicating with the base station via the first DU group and the second DU group.
