Abstract
The present disclosure relates to a pre-5-generation (pre-5G) or 5G communication system to be provided for supporting higher data rates beyond 4-generation (4G) communication system such as long term evolution (LTE). A method and an apparatus for performing a hybrid automatic repeat request (HARQ) for reducing latency in wireless communication systems are provided. The method includes receiving a concatenated packet including a short transmission time interval (TTI) packet and a long TTI packet from a transmitter, decoding the short TTI packet, feeding, when decoding the short TTI packet fails, a negative acknowledgement (NACK) back to the transmitter, and receiving a retransmission packet including the short TTI packet and the long TTI packet from the transmitter.
