Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in adaptively performing beamforming based on user equipment (UE) mobility, leading to inefficient signal transmission and reception.
Innovation Solution
A method and apparatus for transmitting signals using a UE mobility-based precoder cycling technique, where a precoder set is composed and applied in specific resource units, with the size and selection of precoders determined based on the mobility of the reception end, allowing for adjustable beam width and selection of preferred or specific precoders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed precoder set is used for beamforming, then the system structure is simple, but the system cannot adapt to different UE mobility conditions leading to inefficient signal transmission
Solution Approach 1:
The patent implements dynamic precoder cycling where the precoder selection changes over time based on UE mobility conditions. The system transitions from a static precoder assignment to a time-varying precoder cycling mechanism that adapts to different mobility scenarios, resolving the contradiction between adaptability and complexity by introducing controlled dynamics into the precoder selection process
Solution Approach 2:
The patent changes the parameter of precoder selection from a fixed state to a cycling state with multiple precoders applied over time. By modifying the precoder application parameter from static to dynamic cycling, the system achieves adaptability to UE mobility while maintaining manageable complexity through structured parameter changes
2Reliability
If beamforming is applied to improve signal transmission, then signal quality improves, but the system complexity increases due to additional processing requirements
Solution Approach 1:
The patent segments the beamforming process into distinct precoder cycling stages where different precoders are applied in sequence. This segmentation allows the system to achieve reliable signal transmission through multiple beamforming attempts while managing complexity by dividing the overall process into manageable, structured segments rather than requiring complex simultaneous processing
Solution Approach 2:
The patent implements periodic precoder cycling where precoders are applied in a repeating sequence over time. This periodic action improves signal transmission reliability by providing multiple opportunities for successful transmission while maintaining manageable complexity through the regular, predictable pattern of precoder application

AI summary
The present application discloses a method for transmitting a signal from a transmitting end to a receiving end in a wireless communication system. Specifically, the method comprises the steps of: configuring a precoder set including one or more precoders; precoding the signal by cyclically applying the one or more precoders in a specific resource unit; and transmitting the precoded signal to the receiving end, wherein at least one of the size of the precoder set and the one or more precoders is determined on the basis of the mobility of the receiving end.
