1. A method implemented in a wireless transmit-receive unit (WTRU) the method comprising:
receiving first configuration information indicating a configuration of reference signals and second configuration information indicating a configuration of reference information associated with a set of cells of a configurable reflective surface;
receiving the reference signals according to the first configuration information;
selecting, based on measurements performed by the WTRU on the received reference signals, a subset of cells of the configurable reflective surface from the reference information; and
transmitting a reporting message comprising information related to the selected subset of cells of the configurable reflective surface.
