Solution Overview
Problem
Wireless communication systems face interference and network overload issues due to multiple frequency bands, which affect data throughput and user equipment attachment in multi-band wireless base stations.
Innovation Solution
A system that determines Upper Side Lobe Suppression (USLS) levels and network loads across frequency bands, selecting the best frequency band for user equipment attachment based on optimal USLS levels when network loads exceed thresholds, utilizing techniques like vertical beamforming and Carrier Aggregation to minimize interference and optimize traffic management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple frequency bands are used to communicate information over a greater overall frequency band, then the communication capacity and data throughput are improved, but noise and interference occur between the multiple frequencies
Solution Approach 1:
The system dynamically adjusts the upper sidelobe suppression level as a controllable parameter based on real-time interference conditions. When interference is detected between frequency bands, the system modifies the suppression level to mitigate the harmful effects while maintaining communication capacity.
Solution Approach 2:
The patent implements dynamic frequency band selection and upper sidelobe suppression adjustment based on real-time network conditions. The system continuously monitors interference levels and adapts its operation by selecting optimal frequency bands and adjusting suppression levels dynamically rather than using static configurations.
2Object-affected harmful factors
If upper sidelobe suppression is increased to reduce network interference, then interference is reduced, but data throughput may be affected
Solution Approach 1:
The system dynamically adjusts the upper sidelobe suppression level based on real-time interference measurements and network conditions. When interference is low, suppression is minimized to maintain throughput; when interference is high, suppression is increased to protect communication quality, creating an adaptive balance between these conflicting objectives.
Solution Approach 2:
The patent treats the upper sidelobe suppression level as a dynamically adjustable parameter rather than a fixed setting. The system modifies this parameter in response to changing network conditions, allowing optimization of both interference reduction and data throughput based on current operational requirements.
3Quantity of substance
If network load increases on frequency bands, then more user data can be transmitted, but network performance degrades due to overload
Solution Approach 1:
The system implements dynamic frequency band selection based on real-time network load monitoring. When certain frequency bands become overloaded, the system automatically redirects user equipment to alternative frequency bands with available capacity, maintaining network performance while accommodating increased data volume requirements.
Solution Approach 2:
The patent introduces an intermediate decision-making layer that monitors network load across multiple frequency bands and mediates user equipment attachment decisions. This intermediary mechanism selects optimal frequency bands for new connections based on current load conditions, preventing any single band from becoming overloaded while maximizing overall data transmission capacity.

AI summary
A method of operating a multi-band wireless base station to optimize traffic management on the multiple frequency bands. The wireless base station determines Upper Side Lobe Suppression (USLS) levels and network loads on the frequency bands. The wireless base station receives a request from a User Equipment (UE) attachment. When the network loads on the frequency bands exceed corresponding network thresholds, then the wireless base station selects one of the frequency bands having a best one of the USLS levels, and attaches the UE to the selected one of the frequency bands.
