Communication via Uplink and Downlink Reflective Devices - A simplified explanation of the abstract
This abstract first appeared for US patent application 18157682 titled 'Communication via Uplink and Downlink Reflective Devices
Simplified Explanation:
The patent application describes a communication system that includes a base station, user equipment, and reconfigurable intelligent surfaces (RIS's). The system optimizes wireless performance by reflecting downlink (DL) signals off a DL RIS to the UE device and reflecting uplink (UL) signals off a UL RIS to the BS.
Key Features and Innovation:

Original Abstract Submitted
A communication system may include a base station (BS), user equipment (UE), and a set of reconfigurable intelligent surfaces (RIS's). The RIS's, the UE, and the BS may communicate using a control RAT and a data RAT. The BS may transmit downlink (DL) signals to the UE device via reflection off a DL RIS. The UE device may transmit uplink (UL) signals to the BS via reflection off a UL RIS. This may optimize wireless performance in situations where reflecting the UL and DL signals off the same RIS would limit performance under the current data RAT channel conditions. The BS and the UE device may use channel measurements of the control RAT at the RIS's to select the UL RIS and the DL RIS. This may significantly reduce overhead required to identify the UL and DL RIS's relative to scenarios where exhaustive beam training is used.
