Abstract:
[Object] To enable more appropriate recognition of an interference situation of a directional beam. [Solution] Provided is an apparatus including: an acquisition unit that acquires a weight set for forming a directional beam; and a control unit that multiplies a reference signal for channel quality measurement by the weight set. The weight set is a weight set that is able to be generated from a first weight set for acquiring directivity in a first direction, a second weight set for acquiring directivity in a second direction, and a third weight set for phase adjustment of dual layer multiple-input multiple-output (MIMO). The third weight set is a specific one of a plurality of weight sets for phase adjustment of dual layer MIMO.
