Adaptive Resource Cell Generation for Network Coverage Enhancement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network technologies face challenges in effectively managing network interference due to excessive access node density and fixed deployment of base band units (BBUs) and remote radio units (RRUs), which hinder adaptive adjustments to meet changing network coverage requirements.
Innovation Solution
A method is introduced where a correlation matrix is generated to determine the resource cell each access point should subordinate to, allowing for system-level resource management and adaptive adjustment of network coverage by redividing resource cells and reconstructing middlehaul links based on real-time network state changes.

Engineering Contradiction Analysis
1Area of stationary object
If the network transforms to heterogeneous dense network with macrocell and femtocell base stations, then the network coverage is enhanced, but the resource usage conflict aggravates and interference increases
Solution Approach 1:
The patent segments the network into virtual cells formed by grouping multiple physical base stations (macrocell and femtocell) under a common virtual cell identifier. This segmentation allows independent resource management for each virtual cell, reducing interference between cells while maintaining dense deployment for coverage enhancement.
Solution Approach 2:
The patent merges multiple physical base stations into a unified virtual cell structure, where multiple macrocell and femtocell base stations share the same virtual cell ID. This merging enables coordinated resource allocation and reduces interference through system-level management while maintaining the benefits of dense heterogeneous deployment.
2Adaptability or versatility
If the network uses static physical cells for coverage, then the network structure is simple, but the flexibility to cope with business changes is poor
Solution Approach 1:
The patent introduces dynamic virtual cell formation where base stations can be flexibly grouped into different virtual cells based on real-time traffic patterns and business requirements. The virtual cell configuration can be dynamically adjusted without changing the physical network structure, enabling rapid adaptation to business changes while maintaining operational simplicity.
Solution Approach 2:
The patent changes the network organization parameter from fixed physical cell boundaries to flexible virtual cell groupings. By modifying the virtual cell configuration parameters (which base stations belong to which virtual cell) rather than physical infrastructure, the network achieves high adaptability to business changes without increasing physical complexity.
3Adaptability or versatility
If the C-RAN structure with fixed BBU and RRU deployment is used, then the system-level resource management is achieved, but the nodes are difficult to expand and adjust
Solution Approach 1:
The patent segments the C-RAN architecture into virtual cell units that can be independently configured and managed. Each virtual cell represents a logical grouping that can be expanded or adjusted without reconfiguring the entire C-RAN system, enabling flexible network coverage adjustment while maintaining system-level resource management benefits.
Solution Approach 2:
The patent introduces dynamic virtual cell formation within the C-RAN structure, allowing base stations to be flexibly assigned to different virtual cells based on coverage requirements. This dynamic configuration capability enables the network to adapt to changing coverage demands without requiring physical redeployment of BBUs or RRUs, reducing configuration complexity while maintaining adaptability.

AI summary
A method for enhancing network coverage based on adaptive generation of resource cell. A traditional cell in a network is taken as an initial state of the network. A correlation matrix in a current network state is generated. Whether |ωi,jt−ωi,jt-1|/ωi,jt-1>ε is determined. Each access point is divided into a plurality of resource cells. A CU-DU network mapping table is generated. A middlehaul link of each of the plurality of resource cells is constructed according to the CU-DU network mapping table.
