Engineering Contradiction Analysis
1Productivity
If MIMO antenna elements are used to achieve high data transmission rates, then productivity is improved, but reliability deteriorates due to antenna element failures causing beamforming pattern distortion
Solution Approach 1:
The system performs preliminary detection of antenna element failures and pre-calculates compensation beamforming patterns before actual communication disruption occurs. The management server maintains a database of compensation patterns that can be quickly applied when failures are detected, preventing service degradation rather than reacting after disruption.
Solution Approach 2:
A management server acts as an intermediary between the base station and the failure compensation process. The server receives failure detection information, calculates appropriate compensation beamforming patterns, and transmits correction information back to the base station, centralizing the complex compensation logic and enabling reliable automated response to antenna failures.
2Reliability
If automated failure detection and compensation systems are implemented, then reliability is improved, but device complexity increases
Solution Approach 1:
The complex failure compensation logic is extracted from the base station and placed in a separate management server. The base station only needs to perform simple failure detection and transmit alerts, while the server handles the computationally intensive tasks of analyzing failures and calculating compensation patterns, reducing the complexity burden on individual base stations.
Solution Approach 2:
The system implements a closed-loop feedback mechanism where the base station monitors antenna element status, reports failures to the management server, receives compensation patterns, and applies corrections. This automated feedback loop ensures reliable beamforming recovery without requiring complex manual intervention systems.

AI summary
According to a method of an embodiment of the present disclosure, a method for correcting a beamforming pattern of a base station by an analysis server of a base station management network may comprise the steps of: when network management information is received from a first base station, identifying whether or not the network management information indicates the occurrence of a failure in an antenna element of the first base station; when the network management information indicates the occurrence of the failure in the antenna element of the first base station, analyzing an effect of a beamforming pattern of the first base station and analyzing a change in a cell coverage; on the basis of the result of the analysis, determining a first beamforming pattern for compensating for the failure in the antenna element; and transmitting, to the first base station, information about the first beamforming pattern by including the information in management control information.
