Systems and Methods for Split Control of Reconfigurable Intelligent Surfaces
This abstract first appeared for US patent application 20240258708 titled 'Systems and Methods for Split Control of Reconfigurable Intelligent Surfaces
Original Abstract Submitted
a communication system may include a base station (bs), a user equipment (ue) device, a reconfigurable intelligent surface (ris) having a local controller, and a remote controller. antenna elements on the ris may reflect signals between the bs and ue while exhibiting reflection coefficients. the remote controller may transmit a control model and the ue may transmit local information to the local controller, which generates the reflection coefficients based on the local information and control model. alternatively, the remote controller may transmit the control model to the ue and a codebook to the ris. the ue may transmit an identifier to the ris based on local information and the control model. the local controller may implement reflection coefficients of a codebook entry identified by the identifier. splitting control of the ris in these ways may minimize communication overhead, provide coverage extension for the ue, and optimize privacy.
