Dynamic Beamforming Scheme Switching in 5G User Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current beamforming techniques in user equipment (UE) for 5G networks face challenges in efficiently managing beamforming schemes, particularly in high-SINR scenarios where channel-based beamforming is desirable for optimized system performance, but require additional timing and may not include beamforming gain in each measurement, while codebook-based schemes provide beamforming gain but may not select the best beam.
Innovation Solution
Implementing both channel-based and codebook-based beamforming schemes in UE, allowing dynamic switching based on network conditions, with channel-based beamforming using contemporaneous channel measurements and codebook-based beamforming relying on pre-stored codebooks, and coordinating with gNB for proper beam management and signaling support.

Engineering Contradiction Analysis
1Reliability
If channel-based beamforming is used, then system performance is optimized in high-SINR scenarios, but additional timing is required and beamforming gain may not be included in each measurement
Solution Approach 1:
The patent implements dynamic switching between channel-based beamforming and codebook-based beamforming schemes based on network conditions, specifically SINR levels. The UE and gNB coordinate to select the appropriate beamforming scheme, allowing the system to adapt to varying channel conditions and optimize performance while managing timing requirements efficiently.
2Power
If codebook-based beamforming is used, then beamforming gain is provided, but the best beam may not be selected
Solution Approach 1:
The system dynamically selects between channel-based beamforming (which provides better beam selection accuracy through contemporaneous channel measurements) and codebook-based beamforming (which provides beamforming gain using pre-stored codebooks) based on real-time network conditions and SINR levels, optimizing both beam selection accuracy and power efficiency.
3Adaptability or versatility
If multiple beamforming schemes are supported, then adaptability to varying network conditions is improved, but device complexity increases
Solution Approach 1:
The patent enables dynamic adaptation between different beamforming schemes (channel-based and codebook-based) based on network conditions and SINR levels, with coordinated signaling between UE and gNB to manage the complexity of supporting multiple schemes while maximizing adaptability to varying channel environments.
