Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wired backhaul (optical fibers) is configured for each small cell in high frequency communication, then communication reliability is improved, but deployment cost increases greatly and becomes infeasible in areas where optical fibers are not deployed
Solution Approach 1:
The patent introduces a relay base station as an intermediary node between the remote small cell base station and the core network. This relay base station, which already has wired backhaul connectivity, acts as a mediator to provide wireless backhaul services to small cells in areas where optical fiber deployment is not feasible, thus resolving the contradiction between communication reliability and deployment cost
Solution Approach 2:
The patent replaces the mechanical wired backhaul system (optical fibers) with a wireless backhaul system using relay base stations. This substitution allows small cells to achieve reliable connectivity without the need for physical fiber deployment, significantly reducing deployment costs while maintaining communication reliability
2Ease of manufacture
If wireless backhaul is used without proper device type identification, then deployment cost is reduced, but connection reliability deteriorates due to incompatible communication protocols
Solution Approach 1:
The patent implements preliminary device type identification and reporting mechanisms before establishing wireless backhaul connections. The relay base station and small cell base station exchange device type information during the initial connection setup phase, allowing them to pre-configure compatible communication protocols and parameters, thereby ensuring connection reliability from the outset while maintaining cost-effective wireless deployment
Solution Approach 2:
The patent introduces a feedback mechanism where the small cell base station sends device type reporting information to the relay base station, and the relay base station responds with appropriate configuration parameters. This feedback loop ensures that both ends of the wireless backhaul connection are properly configured for reliable communication, preventing protocol incompatibility issues
3Device complexity
If wireless backhaul base stations transmit data directly without secondary base station configuration, then system complexity is reduced, but data transmission efficiency deteriorates
Solution Approach 1:
The patent segments the wireless backhaul data transmission path into multiple hops through secondary base stations. Instead of direct long-distance transmission, data is transmitted through intermediate secondary base stations that are closer to the target, improving transmission efficiency by breaking down the complex direct transmission into simpler, more efficient segmented transmissions

AI summary
The present disclosure provides a wireless backhaul connection method and device. The method is applied to an LTE base station, and a wireless backhaul base station located within the coverage area of the LTE base station. The method comprises: receiving device type reporting information sent by a wireless backhaul base station, the device type reporting information indicating that a device type of the wireless backhaul base station is a wireless backhaul type; and allocating, according to the device type reporting information, an auxiliary base station to the wireless backhaul base station for wireless backhaul connection. Thus, the disclosed wireless backhaul base station can use an LTE configured auxiliary base station to transmit data to a core network apparatus, thereby increasing the reliability of a wireless backhaul connection while also increasing the data transmission efficiency of a wireless backhaul base station.
