ATG Beam Scheduling for Public-Network Interference Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aeronautical communication systems face challenges in completely suppressing interference from Air To Ground (ATG) base stations to surrounding public network base stations due to the ultra-long coverage of ATG base stations.
Innovation Solution
An interference suppression method and apparatus that calculate the angle range of a shaped beam from an ATG base station to a terminal and determine interference parameters, allowing the system to identify target terminals causing interference. The method prohibits the ATG base station from scheduling these target terminals, thereby reducing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If ATG base stations use ultra-long coverage to serve terminals, then service coverage is improved, but interference to surrounding public network base stations increases
Solution Approach 1:
The patent applies local quality by making different parts of the ATG base station's service area have different scheduling policies. Terminals in the interference direction (toward public network base stations) are identified as target terminals and prohibited from scheduling, while other terminals continue normal service. This creates localized quality differentiation within the coverage area, allowing the base station to maintain ultra-long coverage while suppressing interference in specific directions.
2Productivity
If ATG base stations schedule all terminals, then system productivity is improved, but air interface resource loss increases due to interference
Solution Approach 1:
The patent extracts target terminals from the overall terminal set by calculating angle ranges and interference parameters. These identified target terminals are then separated from normal scheduling operations and prohibited from being scheduled. This extraction approach allows the system to maintain high productivity for non-interfering terminals while eliminating the harmful impact of interfering terminals on air interface resources.
3Illumination intensity
If ATG base stations transmit with high power, then downlink signal quality is improved, but interference to surrounding base stations increases
Solution Approach 1:
The patent implements preliminary anti-action by proactively identifying target terminals through angle range calculation and interference parameter analysis before scheduling decisions are made. By determining which terminals would cause interference in advance and prohibiting their scheduling, the system prevents interference from occurring in the first place, rather than attempting to mitigate it after the fact. This allows high power transmission to continue for non-target terminals while preventing harmful interference.

AI summary
The present disclosure provides an interference suppression method and apparatus, a storage medium, and an electronic apparatus. The method comprises: calculating the angle range of a formed beam of a first base station to a first terminal, and calculating an interference parameter between the first base station and a second base station; determining, according to the angle range of the formed beam and the interference parameter, whether the first terminal is a target terminal; and if the first terminal is the target terminal, the first base station prohibiting scheduling of the first terminal.
