Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices face challenges with poor connectivity, complexity, and high cost due to the need to support multiple frequencies, bandwidths, and communication standards, especially in distributed MIMO systems, leading to bulky and costly UEs.
Innovation Solution
The formation of a reconfigurable virtual user equipment (RVUE) by a group of transceiver devices, which collaborate to share resources and appear as a single device to the network, optimizing hardware requirements and improving connectivity through spatial diversity and multiplexing.

Engineering Contradiction Analysis
1Reliability
If a single UE supports multiple frequencies, bandwidths, and communication standards to maintain good connectivity, then connectivity reliability is improved, but device complexity and cost increase
Solution Approach 1:
Multiple UEs are merged into a single virtual UE that appears as one device to the network. The individual UEs share their antenna resources and communication capabilities collectively, so each UE only needs to support a subset of frequencies and standards rather than all of them individually, reducing individual device complexity while maintaining overall connectivity reliability.
Solution Approach 2:
The virtual UE structure allows different physical UEs to perform different functions - some handle specific frequency bands while others handle different communication standards. This multi-functional arrangement at the virtual level enables the system to provide comprehensive connectivity without requiring each individual UE to be universally capable.
2Productivity
If D-MIMO systems are deployed to provide better coverage and multi-user connectivity, then system capacity is improved, but deployment complexity and transport needs increase
Solution Approach 1:
The D-MIMO system is segmented into multiple independent physical UEs that can be deployed and managed separately, rather than requiring a monolithic complex system. Each physical UE is a simple device that can be independently configured, and they are coordinated through the virtual UE framework, simplifying deployment while maintaining the capacity benefits of distributed MIMO.
3Reliability
If dense network deployment is implemented to improve cellular connectivity at higher frequencies, then connectivity quality is improved, but network complexity and cost increase
Solution Approach 1:
Multiple physically separated UEs are merged into a virtual UE that presents a unified interface to the network. This allows the network to treat the distributed UEs as a single connected unit, reducing the perceived network complexity while maintaining the connectivity benefits of having multiple distributed devices, especially important for higher frequency operations.
