Engineering Contradiction Analysis
1Reliability
If conventional beamforming techniques are used requiring terminal feedback for beam selection, then transmission beam optimization is improved, but signaling complexity and electromagnetic pollution increase
Solution Approach 1:
The base station performs self-configuration by automatically determining the coverage area and selecting optimal transmission beams without requiring feedback or measurements from terminals. The system uses environmental sensing and geometric algorithms to autonomously configure beamforming parameters, eliminating the need for complex terminal-base station signaling interactions.
Solution Approach 2:
The base station pre-determines the coverage area and optimal beam directions before actual communication begins. By performing beam selection and configuration in advance based on environmental data and geometric calculations, the system avoids the need for real-time feedback loops and terminal measurements during operation.
2Reliability
If conventional beamforming techniques are used requiring terminal feedback for beam selection, then transmission beam optimization is improved, but energy consumption increases
Solution Approach 1:
The base station autonomously configures transmission beams using environmental sensing and geometric algorithms without requiring energy-consuming feedback transmissions from terminals. The system self-determines coverage areas and optimal beam directions, eliminating the continuous energy expenditure associated with terminal measurements and feedback signaling.
3Measurement precision
If pilot signals are transmitted in all directions for terminal measurements, then channel quality assessment is improved, but electromagnetic pollution increases
Solution Approach 1:
The invention extracts and removes the need for omnidirectional pilot signal transmission by using environmental sensing data and geometric algorithms to directly determine coverage areas and beam directions. This eliminates the harmful electromagnetic radiation from exhaustive pilot signals while retaining the ability to assess and optimize channel quality through alternative means.
Solution Approach 2:
The base station self-determines optimal beam directions using environmental data without relying on terminal measurements obtained through polluting omnidirectional pilot signals. The system autonomously configures beams based on pre-acquired environmental information and geometric calculations.
4Adaptability or versatility
If not all terminals are capable of performing channel measurements, then compatibility is improved, but beamforming performance deteriorates
Solution Approach 1:
The base station performs self-configuration without requiring any terminal capabilities for channel measurements or feedback. By autonomously determining coverage areas and selecting beams using environmental sensing and geometric algorithms, the system achieves universal compatibility with all terminal types while maintaining beamforming performance through base station-side intelligence.

This approach simplifies beam selection, reduces signaling complexity, allows all terminals to benefit from beamforming gains, minimizes pilot signal transmission, and enhances user privacy by directing beams only where needed, while maintaining compatibility with adaptive beamforming techniques.
Implementation Method 1
This energy concentration is achieved electronically by applying phase shifts to the signal emitted by each antenna of the transmitting device, so that the signals received at the receiver antennas combine coherently.
