Abstract: A method includes identifying a zone blocked from line of sight (LOS) of a gNB; receiving a 3D spatial map of a first area including the zone and a second area that surrounds the zone and that is within both a coverage area and the LOS of the gNB; determining whether the second area includes a mountable surface to which a passive RF reflective metasurface is attachable; and determining whether the metasurface, if attached to the mountable surface, generates a reflection path to the zone, based on a determination that the second area includes the mountable surface and based on estimated propagation paths from the gNB to the zone. The method includes determining whether to add a metasurface to the second area based on: a determination result whether the reflection path from the metasurface attached to the mountable surface to the zone includes reflected signals satisfying a threshold bandwidth condition.
