Base Station Beam Emphasis and Deemphasis for Earth Station Interference
Solution Overview
Problem
Current base station technologies lack mechanisms to manage radio beams effectively, leading to out-of-band emission interference with earth stations, particularly from user devices like drones and autonomous vehicles, resulting in resource wastage and communication losses.
Innovation Solution
A controller system that identifies and manages radio beams by creating lists of beams to be emphasized or deemphasized based on device and service data, geospatial data, and relational data, using dynamic and static context to optimize beam control and reduce interference with earth stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If base stations transmit radio beams to serve user devices, then communication service coverage is improved, but out-of-band emission interference to earth stations increases
Solution Approach 1:
The patent applies local quality by differentiating beam treatment based on spatial location and service type. Beams are categorized into emphasized beams (for infrastructure and mobile devices) and deemphasized beams (for stationary devices near earth stations). This local differentiation allows the system to provide high-quality service where needed while minimizing harmful emissions in specific directions toward earth stations.
Solution Approach 2:
The patent implements parameter changes by dynamically adjusting beam parameters (such as power levels, directionality, and activation status) based on real-time conditions. The controller system modifies beam characteristics by adding devices to emphasized or deemphasized lists, thereby changing the physical parameters of radio transmission to balance service coverage with interference reduction.
2Reliability
If base stations use traditional beam transmission without management mechanisms, then device connectivity is maintained, but computing and networking resources are wasted
Solution Approach 1:
The patent applies dynamics by implementing a dynamic beam management system that continuously adapts beam configurations based on real-time device status, location, and service requirements. The emphasized and deemphasized beam lists are updated dynamically, allowing the system to respond to changing conditions and optimize resource allocation while maintaining reliable connectivity for devices that require it.
Solution Approach 2:
The patent segments the beam management system into distinct categories (emphasized beams and deemphasized beams) with different resource allocation strategies. This segmentation allows the system to apply different control policies to different device groups, maintaining connectivity for mobile and infrastructure devices while reducing resource consumption for stationary devices near earth stations.
3Reliability
If base stations maintain continuous communication with all user devices, then service reliability is improved, but interference with earth stations increases
Solution Approach 1:
The patent applies local quality by implementing location-aware beam management that considers the spatial relationship between user devices, base stations, and earth stations. Devices are classified into different categories based on their location and mobility characteristics, with stationary devices near earth stations receiving deemphasized beam treatment while mobile devices receive emphasized beam treatment, thereby maintaining service reliability where appropriate while reducing interference in sensitive areas.
Solution Approach 2:
The patent implements partial action by providing differentiated levels of communication service to different device groups. Rather than uniformly reducing all transmissions, the system applies partial beam emphasis or deemphasis based on device category, ensuring adequate service reliability for mobile and infrastructure devices while applying sufficient reduction for stationary devices to protect earth stations from interference.
Data Source
AI summary
A device may receive data identifying user devices within a geographical area of a base station, respective services provided by the base station to the user devices, the geographical area, an earth station within the geographical area, an infrastructure within the geographical area, and other base stations located geographically adjacent to the geographical area. The device may determine, based on the received data, interfering beams of the base station that interfere with the earth station, and may include data identifying the interfering beams, in a first list of beams to be deemphasized. The device may determine, based on the received data, beams of the base station to be emphasized based on the infrastructure, and may include data identifying the beams to be emphasized, in a second list. The device may control the base station based on the first list and the second list.
