Dynamic Unlicensed Band Assignment for Cellular Data Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cellular networks face insufficient bandwidth on licensed spectrum as demand increases, limiting data transmission performance.
Innovation Solution
Dynamic assignment of unlicensed frequency bands for data flow transmission, where base stations provide unlicensed band assignments to user devices, allowing them to transmit and receive data via both licensed and unlicensed bands, thereby supplementing bandwidth and improving performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If cellular networks operate only on licensed spectrum, then network reliability is maintained, but bandwidth is insufficient to support increasing data transmission demands
Solution Approach 1:
The patent combines licensed and unlicensed spectrum bands into a unified communication system. The base station coordinates transmissions across both band types, merging their capabilities to provide increased bandwidth while maintaining network reliability through centralized control and fallback mechanisms to licensed bands.
Solution Approach 2:
The communication system is designed to operate universally across multiple frequency bands. The base station and user devices can dynamically switch between licensed and unlicensed bands, making the system multi-functional and adaptable to different spectrum conditions while maintaining consistent service quality.
2Productivity
If unlicensed bands are dynamically assigned, then data transmission performance is improved, but system complexity increases
Solution Approach 1:
The base station acts as an intermediary that manages the complexity of unlicensed band assignment. It performs spectrum sensing, selects appropriate unlicensed bands, and coordinates transmissions between user devices and the network. This centralizes the complex decision-making process, improving data transmission performance while containing system complexity within the base station infrastructure.

AI summary
A network device may determine a sequence. The sequence may identify an order in which particular unlicensed bands, of a plurality of unlicensed bands in an unlicensed spectrum, are to be assigned for the transmission of data flows. The network device may provide information identifying the sequence via a licensed band to a user device to cause the user device to transmit or receive the data flows via the particular unlicensed bands identified in the sequence in the order in which the particular unlicensed bands are to be assigned; and transmit or receive, to or from the user device, the data flows via the particular unlicensed and the licensed bands.
