Abstract

Some examples of the techniques described herein may utilize distributed antennas with directivity gam. Distributed antennas may also be utilized as a passive reflector to assist one or more user equipments (UEs) with relatively weak links to a network entity. In some approaches, distributed antennas may achieve directivity while avoiding or reducing increased power consumption. The distributed antennas may also be utilized as a passive reflector when not used for active transmission or reception. For example, distributed antennas may be utilized as a reconfigurable intelligent surface (RIS). A RIS may include a set (e.g., an array) of passive reflecting elements, which can adjust signals incident on the surface via one or more phase shifts of the elements.
