摘要：
PROBLEM TO BE SOLVED: To provide a radio communication method in which a radio base station receives downlink communication quality from a radio terminal device and transmits data to the radio terminal device on the basis of the downlink communication quality.SOLUTION: A radio base station device: generates a prediction pilot for predicting downlink communication quality after predetermined time; transmits the prediction pilot to a radio terminal device prior to transmitting data after the predetermined time; generates a detection pilot by which the radio terminal device processes the data; and transmits the detection pilot to the radio terminal device after the predetermined time. Directional gain of the prediction pilot and that of the detection pilot are the same.
