Abstract
[Object] Provided is a communication apparatus capable of effectively using resources in a case where transmission is performed with directional beams. [Solving Means] Provided is a communication apparatus including a control unit configured to change a setting of scan with a directional beam between beam groups each including a plurality of the directional beams, in which the control unit adjusts the setting of the scan with the directional beam of each of the beam groups depending on a status of an area that the beam group covers.
