1. An uplink transmission method performed by a terminal in a mobile communication network, the uplink transmission method comprising:
receiving resource allocation information from a base station, the resource allocation information allocating uplink resources including at least a first uplink resource and a second uplink resource;
performing first uplink transmission of first data and first hybrid automatic repeat request (HARQ) adaptation information through the first uplink resource; and
performing second uplink transmission of second data and second HARQ adaptation information through the second uplink resource,
wherein the first HARQ adaptation information indicates that the first uplink transmission is initial transmission for the first data; and when the second HARQ adaptation information indicates that the second uplink transmission is retransmission for the first data and the second HARQ adaptation information includes HARQ information indicating that the second uplink transmission is retransmission for the first data, the second uplink transmission is retransmission for the first data,
wherein the first data and the first HARQ adaptation information are transmitted as being multiplexed in the first uplink transmission, and the second data and the second HARQ adaptation information are transmitted as being multiplexed in the second uplink transmission,
wherein each of the first HARQ adaptation information and the second HARQ adaptation information includes at least one of an HARQ process number, a new data indicator (NDI), and a redundancy version (RV), and
wherein the HARQ process number of the first HARQ adapatation information is determined based on a location of the first uplink resource when a retransmission function using periodic uplink resources allocated in a configured grant scheme is not allowed.
