  • Patent number: 11540311
    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.
