1. A method of wireless communication performed by a wireless communication device, the method comprising:
receiving, from a base station, a first request for information associated with a reconfigurable intelligent surface (RIS) based on a proximity of the wireless communication device to the RIS;
transmitting, to the RIS, a second request for information associated with the RIS based on the first request; and
receiving, from the RIS, at least a portion of a signal comprising a watermark based on per-symbol polarization changes, wherein the watermark comprises the information.
