Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data networks face inefficiencies due to high volumes of low-bandwidth devices competing for limited network resources, leading to low useful-to-useless data ratios, especially in uncoordinated environments.
Innovation Solution
A method and system for coordinating satellite and terrestrial base station resource block allocation, where a controller receives data demands from both networks, generates a communication schedule with non-overlapping time and frequency blocks for each base station, and allocates RF resources accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If satellite and terrestrial base stations share the same frequency spectrum without coordination, then spectral efficiency is improved, but interference between networks increases
Solution Approach 1:
The frequency spectrum is segmented into distinct resource blocks for satellite and terrestrial networks. The controller divides available frequency resources into separate allocations, assigning specific resource blocks to each network type to prevent overlapping transmissions and reduce interference while maintaining overall spectral efficiency.
Solution Approach 2:
The resource block allocation is dynamically adjusted based on real-time network conditions, traffic demands, and interference levels. The controller continuously monitors and reconfigures the frequency spectrum segmentation, allowing satellite and terrestrial networks to adaptively share resources without fixed static assignments.
2Device complexity
If uncoordinated resource allocation is used, then system complexity is reduced, but network resource utilization efficiency deteriorates
Solution Approach 1:
A centralized controller acts as an intermediary between satellite and terrestrial base stations, managing resource block allocations centrally. This mediator coordinates frequency spectrum usage, assigns resource blocks, and resolves potential conflicts, thereby improving network resource utilization efficiency without requiring complex peer-to-peer coordination protocols between base stations.
3Quantity of substance
If more frequency resources are allocated to accommodate high volume devices, then network capacity is improved, but useful-to-useless data ratio deteriorates
Solution Approach 1:
Different quality levels of service are provided to different device types and traffic categories. High-priority traffic receives optimized resource block allocations with better spectral efficiency, while low-priority traffic is allocated remaining resources. This local quality differentiation ensures that network capacity is expanded while maintaining high useful-to-useless data ratios for critical applications.

AI summary
Apparatuses, methods, and systems for coordinated satellite and terrestrial base station resource block allocation are disclosed. One method includes receiving, by a controller, a data demand of a terrestrial network of a terrestrial base station and a data demand of a satellite network of a satellite base station, generating, by the controller, a communication schedule comprising satellite resource block information of the satellite base station, wherein the satellite resource block information indicates time and frequency blocks of the communication schedule that the satellite base station is only allowed to use for wireless communication, wherein the time and frequency blocks of the terrestrial resource block information of the terrestrial base station do not overlap with the time and frequency blocks of the satellite resource block information, and allocating, by the satellite base station, radio frequency (RF) resources based on the satellite resource block information.
