Method for transmitting and receiving data in wireless communication system and apparatus therefor

A first User Equipment for transmitting data through sidelink in a wireless communication system supporting Vehicle-to-Everything (V2X) communication, the first User Equipment comprising:

• a Radio Frequency (RF) unit configured to transmit and receive a radio signal;
• and
• a processor functionally connected with the RF unit,
• wherein the processor is configured to perform:
• receiving, from a base station, Downlink Control Information (DCI) including information related to a transmission of first control information, wherein the first control information is used for scheduling data transmitted to a second User Equipment;
• transmitting, to the second User Equipment, the first control information based on the received DCI;
• and
• transmitting, to the second User Equipment, one or more data through the sidelink,
• wherein the DCI is transmitted in subframe #n,
• wherein the first control information is transmitted in subframe #n+k or in a specific sidelink subframe generated after the subframe #n+k,
• wherein the DCI includes second control information indicating a timing gap between a first data transmission and a second data transmission, and
• wherein the second control information is a timing gap field.
