Abstract: A method of receiving, by a user equipment (UE), a reference signal in a wireless communication system. The method includes: receiving downlink control information (DCI) for scheduling downlink data in a first transmission time interval (TTI); acquiring, from the DCI, information related to whether the reference signal is included in the first TTI in which the downlink data is scheduled; and receiving, in the first TTI, the reference signal for the first TTI based on the information related to whether the reference signal is included in the first TTI. The method further includes, based on the downlink data scheduled to be repeatedly transmitted in the first TTI and at least one second TTI: receiving, in each of the at least one second TTI, a reference signal for the each of the at least one second TTI.
