Engineering Contradiction Analysis
1Reliability
If beamforming and massive MIMO technologies are used to mitigate radio-wave path loss and increase transmission distance in mmWave bands, then transmission distance and signal reliability are improved, but system complexity and device complexity increase
Solution Approach 1:
The patent segments beam management into multiple stages: beam sweeping for initial access, beam refinement for connection maintenance, and beam recovery for failure scenarios. This segmentation allows the system to apply different complexity levels at different stages, reducing overall system complexity while maintaining reliability.
Solution Approach 2:
The patent implements preliminary beam training and reference signal transmission before actual data communication. By pre-establishing beam directions and characteristics through reference signals, the system reduces the complexity of real-time beam management during data transmission while ensuring reliable connectivity.
2Measurement precision
If more reference signal resources are measured and reported by user equipment, then beam management accuracy is improved, but signaling overhead and processing complexity increase
Solution Approach 1:
The patent extracts only the most critical beam management information from the measured reference signals for reporting. Instead of reporting all measured reference signal resources, the system identifies and reports only those parameters essential for beam determination, reducing processing complexity while maintaining beam management accuracy.
Solution Approach 2:
The patent dynamically adjusts the reporting parameters and granularity based on channel conditions, beam width, and service requirements. When channel conditions are stable, reporting frequency and detail are reduced. When conditions change rapidly, the system increases reporting detail, optimizing the balance between accuracy and processing complexity.
