SPATIAL EQUALIZATION VIA RECONFIGURABLE INTELLIGENT SURFACE SELECTION - A simplified explanation of the abstract

  • This abstract for appeared for patent application number 17714451 Titled 'SPATIAL EQUALIZATION VIA RECONFIGURABLE INTELLIGENT SURFACE SELECTION'

Simplified Explanation

This abstract describes methods, systems, and devices for wireless communications. It introduces the concept of a reconfigurable intelligent surface (RIS) that can perform multipath fading equalization. By selecting a RIS in close proximity to a receiving device, the network entity can ensure that the multipath fading between the RIS and the receiver is below a certain threshold. The selected RIS is then configured with a phase matrix to compensate for the multipath fading over the network entity to RIS wireless link. As a result, the receiving device can omit or simplify its equalization procedure, benefiting from the RIS's compensation for multipath fading.


Original Abstract Submitted

Methods, systems, and devices for wireless communications are described. For example, described techniques provide for performing multipath fading equalization at a reconfigurable intelligent surface (RIS), allowing a receiving device to omit an equalization procedure or to perform a simpler equalization. A transmitting device, such as a network entity, may select a RIS that is within a sufficient proximity to a receiving device, such as a user equipment (UE), that multipath fading of the RIS to receiver wireless link is likely to be below a threshold. The network entity may configure the selected RIS with a phase matrix to perform over-the-air equalization to compensate for multipath fading over the network entity to RIS wireless link. The UE may omit an equalization procedure or may perform a simpler equalization procedure as compared to a scenario where the RIS does not compensate for multipath fading.
