Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If independent radio frequency channels are used for access side and backhaul side, then system reliability is improved, but resource utilization deteriorates
Solution Approach 1:
The patent merges the radio frequency channels of the access side and backhaul side into a shared channel. The baseband processing units of both sides connect to the same radio frequency channel through switching mechanisms, allowing dynamic sharing of the channel resources while maintaining independent baseband processing capabilities, thus improving resource utilization without completely sacrificing reliability
Solution Approach 2:
The patent introduces dynamic switching mechanisms that allow the radio frequency channel to be dynamically allocated between access and backhaul functions. The system can switch between different connection states (access state, backhaul state, dual-connection state) based on real-time requirements, making the channel allocation flexible and adaptive rather than static
2Stability of the object's composition
If independent radio frequency channels are used for access side and backhaul side, then channel stability is improved, but device complexity deteriorates
Solution Approach 1:
The patent makes the radio frequency channel universal by enabling it to serve both access and backhaul functions. The same physical channel infrastructure is designed to handle multiple types of traffic and connections, reducing the need for separate dedicated channels while maintaining functional stability through proper switching and protocol management
Solution Approach 2:
The patent segments the system into independent baseband processing units that can be selectively connected to the shared radio frequency channel. This segmentation allows each baseband unit to maintain its own processing stability while sharing the common radio frequency infrastructure, reducing overall system complexity through modular design
3Reliability
If independent radio frequency channels are used for access side and backhaul side, then channel performance is improved, but manufacturing cost deteriorates
Solution Approach 1:
The patent combines multiple radio frequency channel functions into a single shared channel infrastructure, reducing the total number of physical components required. By merging transmit and receive channels into a configurable shared resource, the system reduces manufacturing costs for radio frequency hardware while maintaining performance through intelligent switching and resource allocation

AI summary
Embodiments of the present invention relate to the field of network communications and provide a backhaul device and a backhaul device control method. The backhaul device includes: an access-side baseband transmit module, an access-side baseband receive module, a backhaul-side baseband transmit module, a backhaul-side baseband receive module, a radio frequency channel, a first switch module, a second switch module, an access antenna, and a backhaul antenna. Therefore, problems of low resource utilization of a radio frequency channel and high system development costs in the prior art are resolved, and the radio frequency channel can be shared, so as to improve resource utilization. In addition, considering that the radio frequency channel includes multiple components, the radio frequency channel is shared, which reduces a quantity of components required for a system and development costs of the system.
