    Abstract: A non-orthogonal multiple access (NOMA) scheme data receiving method is provided. The method can comprise the steps of: receiving, by a user equipment (UE), downlink control information (DCI) for a NOMA scheme; receiving downlink data on the basis of the DCI; decoding interference data included in the received downlink data; cancelling decoded interference data in the received downlink data if the decoding is successful; and decoding the own downlink data remaining after the interference data has been cancelled.

    Abstract: The present invention relates to a method and apparatus for feeding back channel state information in a wireless communication system supporting a three-dimensional multiple input multiple output (3D-MIMO) antenna. Specifically, the method comprises the steps of: receiving information on N beams, (where N is a natural number), precoded for specific antennas among a plurality of antennas constituting a 3D-MIMO antenna; selecting, from among the N beams, at least one specific beam for which to generate channel state information, and determining interference on the basis of M beams, (where M is a natural number, M≤N−1), among the remaining beams; and generating channel state information for the specific beam on the basis of the interference according to the M beams.

    Abstract: The present invention relates to a wireless access system which supports machine-type communication (MTC), and more specifically, to various methods for establishing the number of hybrid automatic retransmission request (HARQ) processes to support HARQ, and to apparatuses supporting same. A method for establishing the number of HARQ processes in a wireless access system which supports machine-type communication (MTC), according to one embodiment of the present invention, may comprise the steps of: determining, by a base station, the number of HARQ processes to be applied to an MTC terminal; and transmitting, by the base station, downlink control information including a HARQ process value allocated to the MTC terminal from among the determined number of HARQ processes. The number of HARQ processes can be determined on the basis of at least one of the number (N1) of repeated transmissions of a physical downlink control channel (PDCCH) to the MTC terminal, time (F) required for the MTC terminal to receive and process the repeatedly transmitted PDCCH, the number (N2) of repeated transmissions of a physical downlink shared channel (PDSCH), time (p1) required for the MTC terminal to receive and process the repeatedly transmitted PDSCH, the number (N3) of repeated transmissions of a physical uplink control channel (PUCCH), and time (p0) required for the base station to receive and process the repeatedly transmitted PUCCH.
