1Productivity
If traditional antenna arrays are used for signal transmission, then basic communication functionality is maintained, but spectral efficiency and network performance deteriorate in environments with complex interference and varying propagation conditions
Solution Approach 1:
The patent segments the antenna array into multiple independently controllable antenna elements with distinct beamforming capabilities. Each antenna element can be independently configured to transmit or receive signals in specific directions, allowing the system to divide the communication space into multiple beams and thereby improve spectral efficiency through spatial multiplexing while maintaining reliable communication through directional signal transmission that reduces interference
Solution Approach 2:
The patent implements dynamic beamforming where the beam directions, widths, and powers are continuously adjustable based on channel conditions and interference patterns. The network nodes can dynamically reconfigure their antenna element weights and phases to adapt to varying propagation conditions, ensuring both high spectral efficiency in changing environments and reliable communication through real-time optimization of signal transmission characteristics
2Productivity
If antenna elements are strategically placed on radio frequency reflection arrays, then signal transmission and reception are optimized, but device complexity increases
Solution Approach 1:
The patent designs the radio frequency reflection arrays with antenna elements that serve multiple functions: they act as both transmit and receive elements, provide beamforming capabilities, enable channel estimation, and support interference management. This multi-functionality allows the system to achieve optimized signal processing without proportionally increasing device complexity, as the same hardware infrastructure supports multiple communication functions simultaneously
