Method and apparatus for transmitting data based on grant free in wireless communication system

A method performed by a base station in a wireless communication system, the method comprising:

• transmitting, to a terminal, a message including a plurality of grant free resource configurations, the message configuring a correspondence between a grant free resource configuration and hybrid automatic repeat request (HARQ) process number information;
• and
• transmitting, to the terminal, first downlink control information (DCI) including the HARQ process number information,
• wherein grant free resources for grant free resource configurations are released based on the first DCI, and the grant free resource configurations among the plurality of grant free resource configurations correspond to a value of the HARQ process number information, and
• wherein the grant free resources are released based on a value of redundancy version information, a value of modulation and coding scheme information, and a value of frequency domain resource assignment information included in the first DCI.

A terminal in a wireless communication system, the terminal comprising:

• a transceiver configured to transmit or receive a signal;
• and
• a controller configured to:
• receive, from a base station, a message including a plurality of grant free resource configurations, the message configuring a correspondence between a grant free resource configuration and hybrid automatic repeat request (HARQ) process number information,
• receive, from the base station, first downlink control information (DCI) including the HARQ process number information,
• identify grant free resource configurations among the plurality of grant free resource configurations, the grant free resource configurations corresponding to a value of the HARQ process number information, and
• release grant free resources for the grant free resource configurations based on a value of redundancy version information, a value of modulation and coding scheme information, and a value of frequency domain resource assignment information included in the first DCI.
