Abstract

Methods, systems, and devices for wireless communications are described. A first device may include reflective elements and may reflect signals between a second and third device using the reflective elements. In some cases, the first device may receive signaling from the second device indicating a first subset of the reflective elements corresponding to a first phase configuration and a second subset of the reflective elements corresponding to a second phase configuration. In some other cases, the first device may receive signaling indicating a transmission beam of the second device. Here, the first device may identify the first and second subsets of the reflective elements based on an angle of arrival and departure associated with the indicated transmission beam. In either case, the first device may set the phase configurations of the reflective elements according to the first and second subsets.

Dependent claims

A method for wireless communication at a first device comprising a plurality of reflective elements, the method comprising:

receiving signaling indicating a first subset of reflective elements corresponding to a first phase configuration and a second subset of reflective elements corresponding to a second phase configuration, wherein the first subset of reflective elements and the second subset of reflective elements comprise interleaved reflective elements of the plurality of reflective elements;
and
reflecting one or more signals from a second device based at least in part on the first phase configuration for the first subset of reflective elements and the second phase configuration for the second subset of reflective elements.

A method for wireless communication at a first device, comprising:

receiving signaling indicating a transmission beam of a second device, the transmission beam corresponding to an angle of arrival at a plurality of reflective elements of the first device and an angle of departure from the plurality of reflective elements;
identifying, based at least in part on the angle of arrival and the angle of departure, a first subset of reflective elements corresponding to a first phase configuration and a second subset of reflective elements corresponding to a second phase configuration;
and
reflecting one or more signals from the second device based at least in part on the first phase configuration for the first subset of reflective elements and the second phase configuration for the second subset of reflective elements.
