Device Positioning with Reconfigurable Intelligent Surfaces - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240310470 titled 'Device Positioning with Reconfigurable Intelligent Surfaces
The abstract describes a communication system that includes a transmitting device, a receiving device, and one or more reconfigurable intelligent surfaces (RISs). The transmitting device sends a wireless signal received by the receiving device over multiple propagation paths, including paths that reflect off the RISs and paths with other reflections. The receiving device receives location information from each RIS. The receiving device or a control device can modulate the wireless signal with different identifiers when reflected by the RISs, allowing the receiving device to distinguish signals reflected off the RISs from other reflections. The receiving device can determine its position using multilateration based on the received location information and the signals reflected off the RISs.

Original Abstract Submitted
a communication system may include a transmitting (tx) device, a receiving (rx) device, and a one or more reconfigurable intelligent surfaces (ris's). the tx device may transmit a wireless signal received by the rx device over multiple propagation paths including paths that reflect off the ris(s) and paths that include other reflections. the rx device may receive location information from each ris. the rx device or a control device may control each ris to modulate the wireless signal with a different respective identifier upon reflection of the wireless signal by the ris. the rx device may distinguish the wireless signal as reflected off the ris(s) from reflections off other objects based on the ris identifiers modulated onto the wireless signals by the ris(s). the rx device may use a multilateration technique to detect its position based on the received location information and the wireless signals as reflected off the ris(s).
