Abstract: A method of receiving, by a user equipment (UE) that is configured to operate in transmission mode 10, downlink data in a wireless communication system. The method includes: receiving, in a transmission time interval (TTI), downlink control information (DCI) that includes resource element (RE) mapping information. The method also includes receiving, in a plurality of TTIs subsequent to the TTI in which the DCI was received, repeated transmissions of the downlink data to which the RE mapping information has been applied.

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.

Abstract: The present invention relates to a method for an NR (New Radio Access Technology) user equipment to transmit and receive a signal in a wireless communication system and an apparatus therefor. The method comprises the steps of checking a PDCCH (Physical Downlink Control Channel) order and, if the PDCCH order is checked, initiating a random access procedure. In this case, if a first uplink carrier and a second uplink carrier are configured, the random access procedure is configured to transmit a random access preamble via a specific uplink carrier corresponding to an indicator associated with the PDCCH order among the first uplink carrier and the second uplink carrier.
