Method for controlling wireless signal transmission in multi-layer ris
A patent application (Publication Number: US20240039592A1) discloses a method for controlling the transmission of a wireless signal in a wireless telecommunications network using a multi-layer transmissive Reconfigurable Intelligent Surface (RIS). The method involves determining various parameters such as beamforming vectors, phase shift matrices, and combining vectors to optimize wireless communication performance. These parameters are iteratively adjusted until a convergence criterion is met, based on the current wireless communication performance. The method also includes determining phase shift matrices for intermediate transmissive RIS layers if present in the network.
Furthermore, the patent application describes a computer program and a computer-readable carrier medium containing instructions to carry out the method, as well as a device for controlling wireless signal transmission in a network. The device includes a transmitter, a multi-layer transmissive RIS, and processing modules to determine and apply the necessary parameters for optimal communication. The device may be enclosed in a shielded housing for electromagnetic protection. Additionally, the patent application discusses a system in a wireless telecommunications network comprising the described device and receiver, with processing modules distributed across the device, receiver, or external nodes to facilitate efficient signal transmission through the RIS layers.
