Antenna Element Deployment for Mobile Backhaul Bandwidth Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of 5G NR wireless devices puts a high load on wireless networks, particularly on mobile backhaul connections, due to their capability of using higher bandwidths for resource-intensive applications, leading to bandwidth overload and the need to preserve backhaul bandwidth.
Innovation Solution
A method and system where an access node with multiple antenna elements adjusts the deployment of wireless air interfaces based on backhaul usage thresholds, reducing the number of antenna elements operating in concurrent mode (4G LTE and 5G NR) when usage exceeds a threshold, and incrementally reducing them as usage rises to prevent overload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If antenna elements are configured to deploy multiple wireless air interfaces in concurrent mode, then network capacity and service capability are improved, but mobile backhaul bandwidth consumption increases and can exceed threshold levels
Solution Approach 1:
The patent implements dynamic adjustment of antenna element deployment by monitoring backhaul bandwidth usage in real-time and reconfiguring antenna elements between deploying multiple air interfaces or single air interface based on current network conditions. This allows the system to adapt its capacity dynamically rather than operating in a fixed state, resolving the contradiction between maintaining high network capacity and controlling backhaul bandwidth consumption.
Solution Approach 2:
The system changes the operational parameters of antenna elements by switching between different deployment modes (concurrent mode vs. single interface mode) based on backhaul usage thresholds. This parameter change allows the same physical antenna elements to operate under different configurations, enabling the system to maintain versatility when needed while controlling bandwidth consumption when thresholds are approached.
2Productivity
If all antenna elements operate in concurrent mode deploying both 4G LTE and 5G NR, then network service capability is maximized, but mobile backhaul connection becomes overwhelmed
Solution Approach 1:
The patent implements a feedback mechanism that continuously monitors backhaul bandwidth usage and uses this information to control the deployment configuration of antenna elements. When backhaul usage exceeds predetermined thresholds, the system receives feedback and automatically reconfigures antenna elements to reduce load, ensuring backhaul connection stability is maintained while preserving network service capability when conditions allow.
Solution Approach 2:
The system dynamically adjusts the operational state of antenna elements based on real-time backhaul conditions, switching between concurrent mode and single interface mode as needed. This dynamic behavior allows the system to maximize productivity when backhaul capacity is available while maintaining reliability by reducing load when thresholds are approached, preventing backhaul overload.
3Quantity of substance
If the number of antenna elements deploying dual air interfaces is reduced during high load, then backhaul bandwidth is preserved, but network capacity is reduced
Solution Approach 1:
The patent implements dynamic reconfiguration of antenna elements that allows the system to temporarily reduce capacity in favor of preserving backhaul bandwidth when thresholds are exceeded, then restore capacity when conditions improve. This dynamic adjustment resolves the contradiction by making capacity flexible rather than fixed, allowing the system to prioritize backhaul stability during high load while maintaining full capacity during normal conditions.
Solution Approach 2:
The system changes the deployment parameters of antenna elements from concurrent mode to single interface mode as a controllable parameter adjustment. This parameter change is reversible and conditional, allowing the system to trade capacity for backhaul bandwidth availability when needed, then restore capacity when backhaul conditions improve, effectively managing the contradiction between these two parameters.

AI summary
Preserving a bandwidth of a mobile backhaul by reducing a quantity of antenna elements that can concurrently deploy two or more radio air interfaces including 4G LTE and 5G NR. The reduction of antenna elements using concurrent mode may be performed incrementally, based on the backhaul bandwidth usage meeting different predefined thresholds.
