A communication apparatus includes a control unit configured to measure a terminal-specific reference signal transmitted in a radio resource allocated for each terminal apparatus in units of the radio resource and transmits information indicating a measurement result.

Communication apparatus, communication method, and program

A wireless communication device including a control unit configured to generate information for a terminal device based on information acquired from the terminal device. The control unit outputs a reference signal on a first beam generated with at least two or more different first weighting matrices, generates a second weighting matrix specific to a terminal device in accordance with information transmitted from the terminal device in accordance with the reference signal, and outputs data for the terminal device on a second beam with the first weighting matrices and the second weighting matrix. The wireless communication device can supply an appropriate beam to a terminal device while preventing a problem with overhead or increase in the cost of a wireless device, which are caused by an increasing number of antenna elements when FD-MIMO is used.
