Wireless Backhaul Small Base Station Traffic Type Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
5G networks face challenges in spectrum efficiency and high deployment costs due to the use of traditional wired backhaul links for high-frequency band base stations, which complicates the deployment of small cells and fails to meet diverse traffic requirements across different regions.
Innovation Solution
Deploying wireless backhaul small base stations in different regions to support specific traffic types, allowing User Equipment (UE) to preferentially select base stations matching the required traffic type, such as Internet access or video browsing, for improved service quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wired backhaul links are used for high-frequency band base stations, then network reliability is improved, but deployment complexity and cost increase
Solution Approach 1:
The patent replaces wired mechanical backhaul connections with wireless communication links for small base stations. Small base stations communicate with the core network through wireless backhaul, eliminating the need for physical cable infrastructure and reducing deployment complexity while maintaining network functionality.
Solution Approach 2:
The patent enables small base stations to serve dual purposes: providing both wireless access to user equipment and wireless backhaul connectivity to the core network. This multi-functionality allows a single wireless infrastructure to handle both access and transport functions, simplifying the overall network architecture.
2Ease of manufacture
If wireless backhaul small base stations are deployed to reduce deployment complexity, then ease of manufacture is improved, but service quality for diverse traffic types deteriorates
Solution Approach 1:
The patent implements traffic-type-specific service capability indication at each small base station. Each base station broadcasts its supported traffic types (e.g., Internet access, video browsing, online gaming) through system information, allowing user equipment to select the most appropriate base station for their specific traffic requirements, thereby maintaining high service quality despite wireless backhaul deployment.
Solution Approach 2:
The patent enables dynamic service capability indication where small base stations can update their supported traffic type information in real-time through system information broadcasts. This dynamic adaptation allows the network to respond to changing traffic demands and base station conditions, maintaining optimal service quality.
3Adaptability or versatility
If base stations support multiple traffic types, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent extracts and explicitly indicates only the relevant service capabilities (supported traffic types) in the system information broadcast, rather than transmitting complete base station configuration details. This selective information extraction reduces signaling overhead and simplifies the complexity management for both base stations and user equipment.
