BASE STATION DEVICE, CONTROL METHOD OF THE SAME, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To secure highly precise time synchronization between a master eNB and a slave eNB.SOLUTION: A base station device receives a first radio signal transmitted from another base station device, transmits a second radio signal after first predetermined time is elapsed since the first radio signal is received, acquires from another base station device information on propagation delay in a radio segment between the base station device and another base station device which is calculated on the basis of timing at which the first radio signal is transmitted, timing at which the second radio signal is received, and the first predetermined time in another base station device, and performs control so as to be synchronized in time with another base station device, in accordance with information on the propagation delay and information on the transmission time included in the radio signal from another base station device.
