1. A method for wireless communication, the method comprising:
determining a random reflection parameter for each of one or more reconfigurable intelligent surfaces (RISs), wherein the random reflection parameter is random over time for the one or more RISs; and
obtaining a reflected transmission; and
identifying a RIS, of the one or more RISs, based on the random reflection parameter.
