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: Disclosed herein are a method and apparatus for transmitting/receiving random access signals. A first random access channel (RACH) resource for a first RACH preamble format and a second RACH resource for a second RACH preamble format are configured, separately. The first RACH resource and the second RACH resource are for a UE at which Tx/Rx beam correspondence holds and for a UE at which Tx/Rx beam correspondence does not hold, respectively. A UE can use the first or second RACH resource, depending on whether or not Tx/Rx beam correspondence holds at the UE.
