Disclosed is a 5G or pre-5G communication system for supporting a data transmission rate higher than that of a 4G communication system, such as LTE. Disclosed is a method for receiving data in a wireless communication system, comprising the steps of: receiving, by a terminal, transmission point change information from a first base station connected to a gateway; receiving, by the terminal, the data transmitted from the gateway to the first base station through a second base station serving the terminal; and re-receiving, by the terminal, data, of which the transmission has failed, through a third base station according to a change of a transmission point from the second base station to the third base station on the basis of the transmission point change information, when data transmission from the second base station to the terminal has failed.
