Engineering Contradiction Analysis
1Speed
If beamforming and massive MIMO techniques are used in 5G ultrahigh frequency bands, then data rates and transmission distance are improved, but propagation loss and signal coverage become more challenging to manage
Solution Approach 1:
The patent implements dynamic antenna control by adjusting the radiation angle of base station antennas based on real-time location information of user equipment. The controller dynamically modifies antenna beam directions to track moving users, ensuring optimal signal coverage while minimizing propagation loss in 5G ultrahigh frequency bands.
Solution Approach 2:
The system changes the radiation angle parameter of antennas based on user equipment location data. By adjusting this physical parameter dynamically, the system optimizes signal transmission to reach users effectively while reducing energy loss during propagation through controlled beamforming.
2Area of stationary object
If antenna radiation angle is adjusted to increase coverage area, then signal coverage is improved, but signal intensity at specific locations may be reduced
Solution Approach 1:
The patent applies local quality optimization by directing antenna beams to specific geographic areas where user equipment is located. Instead of uniform omnidirectional coverage, the system concentrates signal energy in targeted locations, providing both extended coverage area and high signal intensity where needed simultaneously.
Solution Approach 2:
The system performs preliminary action by obtaining location information of user equipment before adjusting antenna radiation angles. This advance knowledge allows the controller to pre-position antenna beams to cover areas where users will be, ensuring both broad coverage and intense signal delivery to specific locations.
3Reliability
If channel state information is obtained for massive MIMO system, then system gain is improved, but complexity of information acquisition increases
Solution Approach 1:
The patent extracts only the essential location information from channel state data that is needed for antenna control purposes. By taking out and utilizing only the relevant spatial coordinates rather than processing complete channel state matrices, the system achieves massive MIMO gains while significantly reducing the complexity of information acquisition and processing.

AI summary
An example electronic device for controlling a base station antenna in a wireless communication system includes a communication unit; and at least one control unit electrically connected to the communication unit. The at least one control unit may be configured so as to acquire location information of another electronic device, determine a threshold value based on the location information, determine a radiation angle corresponding to the threshold value, transmit a steering instruction to a base station so as to control an antenna based on the radiation angle, and determine whether the steering of the antenna based on the radiation angle has been carried out or not.
