Cluster-Based Cell Selection for Wider mmWave Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The deployment of millimeter wave (mmW) networks is costly due to the need for extensive infrastructure and maintenance, and network operators face challenges in balancing high-speed data rates with deployment expenses, while mmW technology also presents issues like limited coverage and interference.
Innovation Solution
Implementing a cluster-based cell selection method using user equipment (UE) to select initial clusters within a cluster-based cell, combined with infrastructure sharing among network operators facilitated by blockchain technology, to optimize deployment costs and improve network performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If more base stations are deployed to cover wide area, then system coverage is improved, but deployment cost increases
Solution Approach 1:
The patent combines multiple base stations into a single cluster-based cell structure where multiple base stations work together as one logical cell. This merging approach allows the network to cover wider areas while reducing the number of independent base station deployments, thereby lowering infrastructure costs and simplifying deployment.
Solution Approach 2:
The cluster-based cell structure enables multiple base stations to serve multiple functions simultaneously - they can serve different user equipment devices while maintaining synchronization, and the same infrastructure can support both mmW and FR1 frequency bands, reducing the need for dedicated infrastructure for each technology.
2Speed
If mmW networks are deployed to provide high-speed data rates, then data rate performance is improved, but infrastructure deployment expense increases
Solution Approach 1:
The patent merges mmW and FR1 infrastructure into a unified cluster-based cell structure, allowing high-speed mmW data rates to be provided while sharing the same physical infrastructure. This eliminates the need for separate dedicated mmW infrastructure deployments, reducing deployment expenses while maintaining high-speed performance capability.
3Area of stationary object
If cluster-based cell is used to extend cell range, then coverage area is improved, but initial access complexity increases
Solution Approach 1:
The patent segments the cluster-based cell into multiple clusters, each containing a subset of base stations. This segmentation allows user equipment to perform initial access by first identifying and accessing a specific cluster within the larger cell structure, simplifying the initial access procedure while still enabling extended cell range coverage through the hierarchical organization of multiple clusters.

AI summary
A cell selection method includes selecting, by a user equipment (UE), a cluster-based cell, where the cluster-based cell includes a plurality of clusters, and selecting, by the UE, one or more initial clusters from the plurality of clusters within the cluster-based cell.
