ELECTRONIC DEVICE AND METHOD FOR TRANSMITTING BEAMFORMING SIGNAL

Smart overview of the Invention

The patent application outlines a method and electronic device for enhancing wireless communication through a reconfigurable intelligence surface (RIS). The method involves detecting obstacles that interfere with the communication path between a device and the RIS. By analyzing these obstacles, the system derives phase distortion information for the RIS's unit cells and uses this data to generate beamforming control information. This control information is then transmitted to the RIS to adjust the phase of reflected signals, improving communication effectiveness.

Field of Application

This technology is particularly relevant for communication systems operating in ultra-high frequency bands, such as the millimeter wave (mmWave) spectrum. These systems face challenges like path loss, which can hinder data transmission rates and distances. The invention leverages advanced techniques like beamforming and massive MIMO to address these issues, aiming to enhance signal quality and transmission efficiency in high-frequency communication environments.

Technical Details

The control device central to this invention comprises at least one transceiver and processor. The processor detects obstacles and gathers relevant characteristic information, which is used to determine phase distortions affecting the RIS's unit cells. Subsequently, it calculates beamforming control information, enabling the RIS to adjust signal reflections dynamically. This process ensures optimal signal transmission by compensating for any phase shifts caused by obstacles.

Device Configuration

An electronic device incorporating this technology includes a RIS with numerous unit cells, each capable of being individually controlled. The processor within the device configures beamforming control information, initially based on a first phase vector. Upon detecting obstacles, it updates this information using a second phase vector, ensuring the RIS reflects signals with the necessary phase adjustments for optimal communication.

Terminology and Flexibility

The application clarifies that terms used are for illustrative purposes and should be understood in the context of the described technology. It emphasizes the flexibility of the invention, which can be implemented using hardware, software, or a combination of both. The description acknowledges that terms related to signals, characteristics, and device components are exemplary, allowing for equivalent technical terms to be used in practice.
