Abstract: Phase tracking when joint transmission is performed by a plurality of wireless base stations is easily implemented. The wireless base stations perform coordinated transmission to transmit to the wireless terminal in coordination with a coordinated wireless base station. The wireless base station includes a wireless control unit and a communication unit. The wireless control unit makes an agreement on a reference signal with the coordinated wireless base station that performs coordinated transmission, and generates an agreed reference signal. The communication unit transmits a signal including the reference signal to the wireless terminal in coordination with the coordinated wireless base station. The wireless terminal estimates a frequency error among the wireless base stations that perform coordinated transmission on the basis of the received reference signal.
