Millimeter Wave Base Station Resource Partitioning for Wireless Backhaul
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In millimeter wave wireless communication systems, the deployment of a large number of base stations with limited or no connectivity to a network entity poses challenges for backhaul operations, requiring efficient resource partitioning and coordination to ensure adequate resources for both backhaul and user equipment access.
Innovation Solution
A method where a first mmW base station identifies access demand and determines access and backhaul communication parameters to establish a wireless backhaul link with a neighboring base station, partitioning resources between access and backhaul links to meet communication requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If wireless backhaul links are established between mmW base stations to enable backhaul operations without wired connections, then deployment flexibility and cost are improved, but resource coordination complexity increases
Solution Approach 1:
The patent segments resource coordination by dividing time into dedicated access slots and backhaul slots. Base stations independently manage their own resource partitioning based on local access demand, rather than requiring complex centralized coordination. This segmentation allows wireless backhaul deployment while maintaining manageable coordination complexity through temporal separation of access and backhaul operations.
2Reliability
If resources are allocated for wireless backhaul operations between base stations, then backhaul connectivity is improved, but resources available for user equipment access decrease
Solution Approach 1:
The patent implements periodic time-division multiplexing where each base station alternates between access operations and backhaul operations in dedicated time slots. During access slots, base stations serve UEs; during backhaul slots, they establish wireless backhaul links with neighboring base stations. This periodic alternation ensures both backhaul connectivity and UE access capacity are maintained through temporal separation.
3Productivity
If base stations operate in mmW frequency ranges to provide wireless communication, then coverage area is reduced, but spectral efficiency is improved
Solution Approach 1:
The patent merges multiple small coverage areas of individual mmW base stations into a larger network coverage area through wireless backhaul interconnection. By combining the resources and coverage zones of multiple base stations that can communicate via wireless backhaul, the system achieves extended effective coverage while maintaining the high spectral efficiency benefits of mmW operation.

AI summary
Techniques are described for backhaul operations in a millimeter wave wireless communication system. A first base station of the millimeter wave wireless communication system identifies an access demand and one or more access communication parameters associated with the first base station. The first base station sends information to a second base station indicative of the access demand and the one or more access communication parameters, and determines one or more backhaul communication parameters associated with the second base station of the millimeter wave wireless communication system. The first base station establishes a wireless backhaul link with the second base station via the millimeter wave wireless communication system. The first base station partitions resources between an access link with one or more user equipments and the established wireless backhaul link based at least in part on the access demand, the one or more access communication parameters, or the backhaul communication parameters.
