1Length of stationary object
If beamforming and massive MIMO techniques are used to decrease propagation loss and increase transmission distance, then transmission distance is improved, but device complexity increases
Solution Approach 1:
The patent segments the beam management process into distinct phases (beam sweeping, beam measurement, beam reporting, beam refinement) and divides the beamforming architecture into multiple antenna arrays at both base station and user equipment. This segmentation allows complex beamforming operations to be broken down into manageable steps, reducing overall system complexity while maintaining long transmission distances through coordinated beam management procedures.
Solution Approach 2:
The patent implements dynamic beam management where beams are continuously adjusted and optimized based on channel conditions, mobility states, and traffic requirements. The beamforming parameters are dynamically updated through feedback loops involving beam measurement reports and network control, allowing the system to adapt to changing conditions without requiring overly complex static configurations.
2Adaptability or versatility
If unified radio resource acquisition mechanism is designed to work for various use cases with different coverage requirements, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent designs a universal beam management framework that serves multiple use cases (eMBB, URLLC, mMTC) through a common set of procedures and signaling mechanisms. The same beam sweeping, measurement, and reporting procedures are applied across different service types, with flexibility to adjust parameters rather than requiring separate dedicated mechanisms for each use case, thereby reducing overall system complexity.
Solution Approach 2:
The patent achieves adaptability for different use cases by dynamically adjusting beam management parameters such as beam width, sweeping frequency, measurement timing, and reporting intervals rather than changing the fundamental management architecture. This allows a single unified mechanism to accommodate varying coverage requirements and service demands through parameter optimization.
