Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-frequency band antenna feeder sharing technologies incur extra cost overhead and waste port resources due to dedicated combiner ports that are idle when not in use.
Innovation Solution
Implementing a band-pass filter between radio frequency channels in a base station radio frequency module, where a port of one channel serves as a combiner port connected to another module, eliminating the need for a dedicated combiner port and enhancing port utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dedicated combiner port is set on the RF Module to implement frequency band combination and antenna feeder sharing, then the antenna feeder sharing function is achieved, but the module cost increases and port resources are wasted when the port is idle
Solution Approach 1:
The patent makes the combiner port a shared resource that can be dynamically allocated between different RF modules based on operational needs. Instead of having a dedicated combiner port that remains idle when not in use, the system allows any available port to serve as a combiner port when needed, thereby eliminating waste of port resources and reducing module complexity while maintaining antenna feeder sharing capability
Solution Approach 2:
The system implements dynamic port allocation where the combiner port assignment is not fixed but can be changed based on real-time operational requirements. The method includes determining whether to switch combiner ports between RF modules and executing the switch when conditions are met, allowing the system to adapt dynamically to different working scenarios and optimize resource utilization
2Productivity
If multiple frequency bands share a station requiring an extra antenna feeder system, then spectrum resource utilization is improved, but the system complexity and cost overhead increase
Solution Approach 1:
The patent merges the antenna feeder systems of multiple frequency bands by implementing a shared combiner port mechanism. Different frequency bands (e.g., frequency band 1 and frequency band 2) can share the same antenna feeder through dynamic combiner port allocation, thereby reducing the need for separate feeder systems and lowering overall system complexity while improving spectrum resource utilization
Solution Approach 2:
The system segments the combiner port functionality into dynamically allocatable units that can be assigned to different RF modules as needed. This segmentation allows flexible resource allocation where the same physical port can serve different frequency bands at different times, reducing the total number of required ports and simplifying the overall antenna feeder system architecture

AI summary
Embodiments of the present invention provide a multi-frequency band antenna feeder sharing method and a base station radio frequency unit. The present invention relates to the field of base station technologies. The method includes: when a first radio frequency module works in set-in combiner mode, receiving a signal of a frequency band 1 and a signal of a frequency band 2 through an antenna feeder, transmitting the signals to a band-pass filter and filtering the signals so as to obtain the signal of the frequency band 2, and transmitting the signal of the frequency band 2 to a third radio frequency port through a combiner port; and/or, when the first radio frequency module works in set-in combiner mode, sending the signal of the frequency band 2 to the combiner port through the third radio frequency port, transmitting the signal of the frequency band 2 that has passed through the band-pass filter to the port of the first radio frequency channel, and sending out the signal of the frequency band 2, together with the signal of the frequency band 1, through the antenna feeder.
