More Information
Summary:A base station according to an embodiment supports full-dimension MIMO (FD-MIMO). The base station includes: an antenna array having antenna elements arranged two-dimensionally in a horizontal direction and a vertical direction; and a controller configured to perform a process of transmitting a dedicated reference signal that is a reference signal used for measurement of channel characteristics and is individually generated for a radio terminal. The controller is configured to select a specific target radio terminal from among target radio terminals to be connected to the base station, and perform a process of transmitting the dedicated reference signal only to the specific target radio terminal.
