Abstract: Disclosed are a method and a device for transmitting and receiving an aperiodic reference signal. The method for receiving an aperiodic reference signal comprises: allowing a reference signal receiving device to determine a radio resource area that can be calculated by environmental information from a first reference signal transmission device, and to transmit an aperiodic reference signal to the first reference signal transmission device by including first instruction information which instructs the aperiodic reference signal to be transmitted in the radio resource area; transmitting the aperiodic reference signal by including second instruction information which instructs a second reference signal transmission device, to which a periodic reference signal is to be transmitted in said radio resource area; and receiving the aperiodic reference signal from the first reference signal transmission device in the radio resource area.
