    Abstract: The present invention relates to a method and an apparatus for receiving a user equipment signal for vehicle to everything (V2X) communication in a wireless communication system. Particularly, the method comprises the steps of: receiving a V2X signal in a time domain; and acquiring, from the V2X signal, V2X data in resource elements, which correspond to a plurality of sub-carriers determined according to a specific pattern among the sub-carriers configured for the user equipment and have a specific symbol index, wherein the V2X data is allocated so as to be separated, on the plurality of sub-carriers, as far as an interval determined according to the specific pattern in a frequency domain, and the V2X signals are characterized in that V2X data signals are repeated and represented the number of times corresponding to the specific pattern at a time interval corresponding to one symbol in the time domain.

    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.
