Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional beamforming techniques are used in complex and dynamic environments, then signal transmission can be maintained, but signal quality deteriorates due to attenuation and blocking
Solution Approach 1:
The patent implements dynamic beamforming where the network entity and UE independently determine and adjust beam weights based on real-time channel conditions. The beam weights are calculated using received signal strength measurements and channel state information, allowing the system to adapt to changing environmental conditions such as signal attenuation and blocking, thereby maintaining reliable signal transmission.
2Productivity
If adaptive beamweight determination is implemented at both network entity and UE, then signal quality and data rates are enhanced, but device complexity increases
Solution Approach 1:
The patent enables both the network entity and the UE to independently perform beamweight determination using their own measurements and calculations. The UE measures reference signals, calculates beam weights based on received signal strength, and determines adaptive beamforming parameters autonomously. Similarly, the network entity performs independent beamweight determination. This self-service approach enhances productivity through adaptive beamforming while managing device complexity by distributing the processing burden rather than requiring complex centralized control.
3Area of stationary object
If multiple beams are combined to form adaptive beams, then coverage area is extended, but processing requirements increase
Solution Approach 1:
The patent implements beam combining where the UE measures reference signals from multiple beams and combines them to form adaptive beams. The system processes a subset of available beams rather than all possible beams, using partial action to extend coverage area while managing processing power requirements. The beam combination is performed selectively based on measured signal qualities, achieving enhanced coverage without requiring excessive processing resources.

AI summary
Certain aspects of the present disclosure provide techniques for user equipment (UE)-based two-sided adaptive beam weight determination. An example method, performed at a user equipment (UE), generally includes measuring reference signals (RSs) associated with a set of beams, calculating, based on the measuring, first coefficients for combining a first subset of the set of beams to form a first adaptive beam, transmitting information regarding 1) the first coefficients, and 2) one or more identifier (IDs) associated with the first subset of beams, and processing, after transmitting the information, at least one transmission in accordance with the first adaptive beam.
