Provided is a method of transmitting a signal related to a change in a transmission format. In a wireless communication system which uses an orthogonal frequency division multiplexing (OFDM) symbol or a single carrier-frequency division multiple access (SC-FDMA) symbol, the method includes: transmitting, from a base station to a receiver, a radio resource control (RRC) message indicating that a first transmission format is changed to a second transmission format; and if an acknowledgement (ACK) message for the RRC message is not received, repetitively transmitting the RRC message, from the base station to the receiver, together with data based on the first transmission format or data based on the second transmission format, wherein the data based on the first transmission format and the data based on the second transmission format transmitted together with the RRC message are alternately selected.
