Shared Cell Networking to Eliminate Cell-Boundary Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cellular communications, interference and signal degradation occur at cell boundaries due to multi-path propagation, leading to low signal-to-interference-plus-noise ratio and reliability issues, which existing UE devices struggle to address effectively.
Innovation Solution
Implementing communication functionality in existing hardware components like NIC, DPU, or network switch to manage cellular communications, eliminating the need for additional Front Haul Multiplexors (FHM), and enhancing signal processing through downlink copying and uplink combining to treat neighboring cells as a unified cell.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If traditional multi-cell deployment is used, then coverage area is expanded, but signal quality and reliability deteriorate at cell boundaries due to interference
Solution Approach 1:
The patent merges multiple neighboring cells into a single shared cell, where all base station antennas transmit the same data to user equipment. This eliminates cell boundaries and the associated interference problems, allowing the network to maintain expanded coverage area while ensuring reliable signal quality throughout the entire service region.
2Object-affected harmful factors
If advanced signal processing techniques are implemented in UE devices, then interference combat capability is improved, but device complexity increases
Solution Approach 1:
Instead of requiring complex UE processing to combat interference, the patent converts the harmful interference from neighboring cells into a beneficial signal by having all base stations transmit identical data. The interference becomes a reinforcement of the desired signal, eliminating the need for complex interference cancellation techniques in UE devices.
3Productivity
If Front Haul Multiplexors are added to manage cellular communications, then signal processing capability is enhanced, but device complexity and cost increase
Solution Approach 1:
The patent makes existing base station antennas and transmission infrastructure multi-functional by using them to transmit data for multiple logical cells simultaneously. Instead of adding dedicated Front Haul Multiplexors, the system reuses existing hardware resources to achieve enhanced signal processing capability through coordinated transmission from multiple base stations.

AI summary
Approaches in accordance with various embodiments enable communication functionality to be added to an existing hardware component, such as a network interface controller (NIC), data processing unit (DPA), or network switch, rather than requiring an additional component such as a Front Haul Multiplexor (FHM)-type for cellular communications. Such an approach not only avoids the cost and complexity of managing additional hardware components, but can also reduce bandwidth needed for signal transmission. For downlink communications, data can be copied to the relevant radio units of a cell in a single cell deployment architecture to be transmitted to a target client device, such as a cellular handset. For uplink communications, data received from a client device to multiple radio units can undergo decompression and channel estimation before combining the data into a single signal or data stream.
