Abstract
The present invention relates to a method for synchronizing multiple cells, which perform cooperative multi-input multi-output operations, as well as to a method for inter-cell synchronization in a multi-cell environment, comprising the steps of: measuring a propagation delay of a cooperative base station; transmitting the measured propagation delay to a serving base station; and receiving data for cooperative multi-input multi-output operations in which a transmission location is adjusted, on the basis of the propagation delay of the cooperative base station, when the serving base station transmits the propagation delay to the cooperative base station.
