Resource allocation method for V2X communication in wireless communication system and apparatus therefor

A first user equipment (UE) operating in a wireless communication system, the first UE comprising:

• a transceiver;
• and
• a processor operationally coupled to the transceiver, wherein the processor is configured to:
• receive, from a network, a first control channel including sidelink resource information on a set of transmission resources for a sidelink data,
• receive, from the network, a second control channel including uplink resource information to report Hybrid automatic repeat request (HARQ)-acknowledgement (ACK) information,
• repeatedly transmit, to a second UE, the sidelink data using the set of transmission resources, and
• transmit, to the network, the HARQ-ACK information generated based on a plurality of feedback received from the second UE,
• wherein the plurality of feedback corresponds to the sidelink data repeatedly transmitted, and
• wherein the HARQ-ACK information is transmitted at a transmission time that is after a last time resource in the set of transmission resources.
