An assembly that attaches a ball grid array packaged camera device to a printed circuit board substrate is provided. The orientation of the volume object, such as a cube or other shaped device, is sensed. Channel-state-information reference symbols, CSI-RS, are transmitted using different CSI-RS resources on different transmission points within the cell, while configuration of CSI-RS measurement resources is conducted on a UE-specific basis. Thus, the use of a space near the inclined face of the reflector allows a liquid crystal monitor to be thinned and reduced in its size and the width of monitor frame.
