Base Station Resource Allocation for Dynamic Backhaul
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems require excessive hardware for point-to-point connections between Base Stations (BSs), leading to increased complexity and cost, and hinder quick and accurate service provision, especially in cooperative communication scenarios where dynamic backhaul link adaptation is necessary.
Innovation Solution
A method and apparatus for efficiently allocating resources between BSs by determining the use of a second resource allocation scheme based on the position information of new and existing BSs, allowing adaptive changes in resource allocation according to the communication environment, using a BS interface unit, storage unit, and resource allocator to manage resource allocations and prevent interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If point-to-point connections are used between BSs, then communication reliability is improved, but hardware requirements and device complexity increase excessively
Solution Approach 1:
The patent merges multiple point-to-point connection functions into a single point-to-multipoint interface. Instead of requiring separate hardware units for each BS connection, a single BS interface unit handles communications with multiple neighboring BSs simultaneously, reducing hardware requirements while maintaining communication reliability through shared resource allocation
Solution Approach 2:
The BS interface unit is designed with multi-functionality to serve multiple purposes: it handles both point-to-point and point-to-multipoint communications, manages resource allocation for multiple neighbors, and performs interference coordination. This universal interface replaces numerous specialized hardware units, reducing device complexity while maintaining reliable communication
2Stability of the object's composition
If point-to-point connections are used between BSs, then communication stability is improved, but service speed and adaptability deteriorate due to excessive hardware demand
Solution Approach 1:
The patent implements dynamic resource allocation where the BS interface unit can adaptively adjust resource configurations based on current communication conditions. The system dynamically selects between different resource allocation schemes (first scheme for stable conditions, second scheme for rapid adaptation) and quickly reconfigures resource partitions when neighbors are added or removed, enabling both stability and rapid service response
Solution Approach 2:
The system changes operational parameters by switching between different resource allocation schemes. The first scheme provides stable, predictable resource distribution for normal operation, while the second scheme enables rapid parameter reconfiguration when network topology changes, allowing the system to maintain stability during operation while achieving fast adaptation when needed
3Ease of operation
If first resource allocation scheme is used for existing BSs, then resource management simplicity is improved, but adaptability to new BS additions deteriorates
Solution Approach 1:
The system performs preliminary actions by pre-configuring resource allocation patterns and having the second resource allocation scheme ready for rapid deployment. When a new BS is added, the system can quickly switch to the second scheme which is pre-designed to handle dynamic additions, then after reconfiguration, returns to the simpler first scheme, maintaining ease of operation while achieving adaptability during transitions

AI summary
A method and an apparatus for allocating resources for communication between Base Stations (BSs) are provided. The method includes when a new BS is added to a network, determining neighboring BSs of the new BS based on position information of the new BS and position information of existing BSs in the network, determining whether to use a second resource allocation scheme based on a first resource allocation scheme currently applied to the existing BSs in the network and a number of resource configurations used by the neighboring BSs, when it is determined to use the second resource allocation scheme, determining resource allocations for communication between the new BS and the neighboring BSs by using the second resource allocation scheme, and when it is determined to not use the second resource allocation scheme, determining resource allocations for communication between the new BS and the neighboring BSs by using the first resource allocation scheme.
