Abstract: A wireless communication device includes a communication circuit configured to receive a channel state information reference signal (CSI-RS), a processor, which includes an angle of departure (AoD) monitoring circuit configured to extract AoD values corresponding to the received CSI-RS and an interference cancellation circuit configured to cancel second AoD values corresponding to an interfering cell adjacent to a serving cell other than first AoD values corresponding to the serving cell among the AoD values, and a memory storing the first AoD values corresponding to the serving cell and antenna array information of the serving cell.

Abstract: A semiconductor device includes an active pattern protruding from a substrate, a gate structure crossing over the active pattern, and source/drain regions disposed on the active pattern at opposite sides of the gate structure. Each of the source/drain regions includes a first epitaxial pattern contacting the active pattern and a second epitaxial pattern on the first epitaxial pattern. The first epitaxial pattern comprises a material having a lattice constant which is the same as that of the substrate, and the second epitaxial pattern comprises a material having a lattice constant greater than that of the first epitaxial pattern.
