1. A first wireless communication device for wireless communication, comprising:
one or more memories storing processor-executable code; and
one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the first wireless communication device to:
set one or more parameters corresponding to one or more columns of a reconfigurable intelligent surface (RIS) based at least in part on a periodic coding sequence;
transmit a first signal to a second wireless communication device using a first harmonic frequency based at least in part on the one or more parameters; and
transmit a second signal to a third wireless communication device using a second harmonic frequency different from the first harmonic frequency based at least in part on the one or more parameters.
