FREQUENCY DEPENDENT CONTROLLING AND IMPULSE RESPONSE FILTERING FOR A RECONFIGURABLE INTELLIGENT SURFACE (RIS)

WIPO Patent Application WO/2022/213357

A1

Aspects of the disclosure relate to a reconfigurable intelligent surface (RIS) controller for controlling a RIS panel to be frequency and/or element dependent, and for operating an adaptive filtering function. The RIS controller may be configured to transmit, to a scheduling entity, a RIS frequency capability indication for indicating communication support of the RIS panel for one or more frequency ranges. The scheduling entity, then, may transmit RIS control information based on the RIS frequency capability indication. In response, the RIS controller may receive the RIS control information and configure the RIS panel based on the RIS control information. Other aspects, embodiments, and features are also claimed and described.
