Abstract: Provided are a method and an apparatus for transmitting grant-free based uplink data in a wireless communication system. Specifically, a terminal receives, from a base station, allocation information for a grant-free uplink resource that is semi-statically allocated. The terminal receives, from the base station, allocation information for a first reference signal used for initial transmission of uplink data and allocation information for a second reference signal used for retransmission of the uplink data. The terminal transmits the uplink data through the grant-free uplink resource by using the first reference signal. If decoding of the uplink data fails, the terminal receives, from the base station, an uplink grant corresponding to the second reference signal. The terminal retransmits the uplink data by using the second reference signal on the basis of the uplink grant. The first reference signal is commonly allocated to the terminal, and the second reference signal is specifically allocated to the terminal.

Abstract: Provided are a method and an apparatus for transmitting uplink data in a wireless communication system. Specifically, a first terminal transmits a random access preamble for requesting a connectionless transmission. The first terminal receives a random access response comprising scheduling information of the uplink data. The first terminal transmits uplink data and a reference signal from a first resource configured on the basis of scheduling information of the uplink data and information indicating the CP length of the reference signal. The CP length of the reference signal can be configured to be identical to the CP length of the random access preamble. The first resource can correspond to a resource utilized by both the first terminal and second terminal.
