Techniques for establishing directional communications via a configurable reflective surface

An apparatus for wireless communication at an assisting node (AN), comprising:

• a first interface configured to:
• obtain an indication of resources for training communications via a configurable reflective surface, the resources associated with training occasions, wherein each training occasion includes a plurality of sub-occasions and wherein each sub-occasion includes a plurality of measurement occasions;
• the first interface, a second interface, or a processing system, or any combination thereof, configured to:
• control, during a training occasion, the configurable reflective surface in accordance with a respective reflection parameter value of a plurality of reflection parameter values for each measurement occasion of the plurality of measurement occasions associated with the respective training occasion;
• the first interface or the second interface configured to:
• obtain, from a first node, an indication of one of the plurality of reflection parameter values;
• and
• the first interface, the second interface, or the processing system, or any combination thereof, configured to:
• control, for communications between the first node and a second node, the configurable reflective surface in accordance with the indicated one of the plurality of reflection parameter values.

A method for wireless communication at an assisting node (AN), comprising:

• communicating with a first node in accordance with a parameter for directional reception of signals from the first node;
• communicating with a second node in accordance with a parameter for directional transmission of signals to the second node;
• and
• controlling a reflection characteristic of a configurable reflective surface in accordance with the parameter for directional reception of signals from the first node and the parameter for directional transmission of signals to the second node.
