Problem
Current wireless communication systems, such as LTE, face limitations in enhancing MIMO technology for better communication efficiency, particularly in achieving competitive performance with rising user and service provider demands, and require advancements in beam forming techniques to improve data transmission rates and interference reduction.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional 2D beam forming is used in LTE systems, then device complexity is kept manageable, but communication efficiency and data transmission rates cannot meet rising user demands
Solution Approach 1:
The patent transitions from conventional 2D beam forming (horizontal plane only) to 3D beam forming by adding the vertical dimension. This is achieved by configuring antenna ports in a three-dimensional space with both horizontal and vertical spacing, enabling the system to form beams in 3D space and thereby increase data transmission rates without proportionally increasing device complexity
Solution Approach 2:
The patent segments the precoding process into horizontal and vertical components. By separately configuring horizontal and vertical spacing between antenna ports and applying independent precoding matrices for each dimension, the system manages the complexity of 3D beam forming through modular segmentation rather than treating it as a monolithic complex operation
2Productivity
If MIMO technology is enhanced with advanced beam forming, then frequency efficiency improves, but interference management becomes more challenging
Solution Approach 1:
The patent applies local quality by configuring different horizontal and vertical spacing between antenna ports based on specific deployment scenarios. This allows the system to optimize beam forming characteristics for local conditions, improving frequency efficiency while managing interference adaptively rather than applying a uniform approach across all antenna configurations
Solution Approach 2:
The patent changes physical parameters (horizontal and vertical spacing between antenna ports) to optimize beam forming performance. By adjusting these spacing parameters, the system can control beam width, direction, and interference patterns, thereby improving frequency efficiency while managing interference through parameter optimization
3Reliability
If 3D beam forming with user equipment-specific elevation beamforming is implemented, then SINR is enhanced and system performance improves, but the complexity of precoding matrix management increases
Solution Approach 1:
The patent segments the precoding matrix into horizontal and vertical components, where each component corresponds to a specific dimension. This segmentation allows the system to manage complex 3D precoding by handling horizontal and vertical precoding separately, reducing the overall complexity of precoding matrix management while maintaining high SINR through coordinated 3D beam forming
Solution Approach 2:
The patent creates a universal framework for 3D beam forming that can be applied across different LTE deployment scenarios. By defining standardized methods for configuring horizontal and vertical spacing and applying precoding matrices, the system achieves user equipment-specific elevation beamforming with improved SINR while keeping the management approach universally applicable and not overly complex

AI summary
Here, operation for 3D beam forming is disclosed. UE, receiving reference signals from one or more base stations (eNBs), may report feedback information comprising precoding matrix information to the one or more eNBs. The precoding matrix information indicates a first type precoding matrix for a horizontal direction and a second type precoding matrix for a vertical direction. eNBs may transmit signals, which are precoded based on a third type precoding matrix for beam forming both on the horizontal direction and the vertical direction.
