1. A method of transmitting a data block in a wireless communication system, the method comprising:

  • transmitting, by a transmitter, the data block to a hybrid automatic repeat request (HARQ) entity of a receiver;

    receiving, by the transmitter from the HARQ entity of the receiver, a HARQ not-acknowledgement (NACK) indicating a reception failure, by the receiver, of the data block due to an acknowledgement (ACK)-NACK error that occurs when the HARQ NACK transmitted by the HARQ entity of the receiver is actually a HARQ ACK;

    receiving, by the transmitter from an automatic repeat request (ARQ) entity of the receiver, an ARQ feedback message indicating a reception success, by the receiver, of the data block,wherein a polling indicator is transmitted for triggering transmission of the ARQ feedback message,wherein the ARQ feedback message is periodically transmitted using a header of a medium access control (MAC) protocol data unit (PDU),wherein the ARQ feedback message is transmitted by the ARQ entity of the receiver after performing the steps of;

    detecting the NACK-ACK error by the HARQ entity of the receiver; and

    transmitting internal signaling for reporting the NACK-ACK error by the HARQ entity of the receiver to the ARQ entity of the receiver,wherein the ARQ feedback message is transmitted without a normal resource request procedure; and

    confirming, by the transmitter, the reception success of the data block by using the ARQ feedback message.
