Abstract
Methods, systems, and devices for wireless communications are described. Repetitions of a reference signal may be transmitted by a first device. In some examples, the repetitions may be quasi-colocated with one another, share an antenna port, or both. The repetitions of the reference signal may arrive at a reconfigurable surface. The reconfigurable surface may apply a modulation sequence to the repetitions of the reference signal and output modulated repetitions of the reference signal in a direction based on a reflective state of the reconfigurable surface. A signal including the modulated repetitions of the reference signal may be received by a second device and combined with the modulation sequence used by the reconfigurable surface to obtain a combined signal. The combined signal may be used to determine, for the reconfigurable surface, information about a channel between the first device and the second device.
