Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The frequent handovers and power consumption of user equipment (UE) in dense cellular networks, along with wastage of downlink resources due to paging in multiple small cells, are significant issues in current cellular network architectures.
Innovation Solution
A network access method that aggregates multiple small cells into a super cell, allowing UE to perform downlink synchronization and access based on configuration information from a single system message, reducing unnecessary measurements and handovers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If each small cell is configured as an independent cell in dense cellular networks, then the network capacity and spectrum utilization are improved, but the user equipment needs to perform frequent downlink synchronization and cell handovers, resulting in increased power consumption
Solution Approach 1:
The patent combines multiple small cells into a single cell structure, where multiple transmission points (small cells) are aggregated under one cell identity. This allows UE to perform downlink synchronization once at the cell level rather than at each small cell level, reducing the frequency of synchronization operations and thereby reducing power consumption while maintaining the network capacity benefits of dense small cell deployment
2Productivity
If each small cell operates as an independent cell, then the system can support more users through cell splitting, but downlink resources are wasted when paging UE across multiple small cells since the UE is located in only one small cell
Solution Approach 1:
By merging multiple small cells into a single cell with a unified cell identity, the patent enables centralized paging operations at the cell level rather than distributing paging across multiple independent small cells. This reduces downlink resource wastage by eliminating redundant paging transmissions to the same UE across multiple small cells, while the underlying small cell structure maintains high system capacity
3Reliability
If UE performs downlink synchronization at each small cell entry, then the UE can maintain accurate synchronization with each cell, but a large amount of power consumption is wasted due to frequent synchronization operations in the moving process
Solution Approach 1:
The patent merges multiple small cells into a single cell structure, allowing UE to perform downlink synchronization at the cell level rather than at each individual small cell level. This reduces the frequency of synchronization operations significantly while maintaining synchronization accuracy through the unified cell structure, thereby reducing power consumption for moving UEs
4Productivity
If multiple independent small cells are deployed, then the spectrum resource utilization rate is improved through frequency multiplexing, but the device complexity and configuration management become more complex
Solution Approach 1:
The patent merges multiple small cells into a single cell with unified configuration management. This reduces the complexity of system message configuration and management by consolidating what would otherwise be multiple independent cell configurations into one, while the underlying small cell structure continues to provide high spectrum utilization through frequency multiplexing
