Radio Base Station Resource Reallocation for Rural Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G New Radio (NR) wireless communication systems face challenges in providing adequate radio coverage, especially in rural areas, where increased bandwidth demand and mission-critical tasks require improved coverage.
Innovation Solution
A method and system where a radio base station temporarily reallocates resources from a high-frequency band at a first location to a second location, upon detecting a need for improved coverage at the second location, allowing wireless communication devices at the second location to establish communication links with higher capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If high-frequency band resources are allocated to provide coverage in both first location and second location, then radio coverage capacity is improved, but coverage reliability for mission-critical tasks in rural areas deteriorates due to resource insufficiency
Solution Approach 1:
The patent implements dynamic resource allocation where the radio base station continuously monitors coverage requirements and temporarily reallocates high-frequency band resources from the first location to the second location when mission-critical tasks are detected. This dynamic adjustment allows the system to adapt resource distribution in real-time, ensuring both locations receive adequate coverage capacity while prioritizing reliability for rural areas when needed.
Solution Approach 2:
The system changes the allocation parameters of frequency band resources based on detected coverage needs. When a wireless communication device at the second location requires improved coverage, the base station modifies the resource allocation parameters by temporarily assigning high-frequency band resources to that location, thereby adjusting the system state to meet reliability requirements for mission-critical tasks.
2Reliability
If high-frequency band resources are dedicated to the second location for improved coverage, then coverage reliability is improved, but radio coverage capacity at the first location deteriorates
Solution Approach 1:
The patent implements periodic monitoring and temporary reallocation of high-frequency band resources. Instead of permanently dedicating resources to the second location, the system periodically assesses coverage requirements and temporarily reallocates resources only when mission-critical tasks are detected. This periodic action ensures the first location maintains its coverage capacity while the second location receives enhanced reliability support when needed.
Solution Approach 2:
The resource allocation is made dynamic rather than static, allowing the system to switch between different allocation states based on real-time requirements. The high-frequency band resources can be temporarily assigned to the second location for improved reliability, then reverted to the first location when no longer needed, thus maintaining overall coverage capacity across both locations.
3Quantity of substance
If low-frequency band resources are used for both locations, then coverage capacity is maintained, but bandwidth demand for new use-cases and applications deteriorates due to insufficient capacity
Solution Approach 1:
The patent merges the capabilities of both low-frequency and high-frequency bands to meet bandwidth demands. The low-frequency band provides baseline coverage capacity for both locations, while the high-frequency band is temporarily combined with this baseline when needed to provide additional bandwidth capacity for new use-cases and applications, thereby satisfying both coverage and productivity requirements.

AI summary
The present disclosure relates to a method of a radio base station (20) of controlling allocation of resources to wireless communication devices (23, 24), and a radio base station (20) performing the method. In an aspect, a method of a radio base station (20) of controlling allocation of resources to wireless communication devices (23, 24) is provided. The method comprises providing (S101) a first location with radio coverage using at least a first frequency band and a second frequency band and a second location with radio coverage using the first frequency band, the second frequency band being located at a higher frequency than the first frequency band and temporarily reallocating (S102) resources of the second frequency band from the first location to the second location upon acquiring an indication that a wireless communication device (24) at the second location requires improved coverage.
