A method for transmitting and receiving downlink data in a wireless communication system includes the steps of: transmitting a preamble for random access; receiving a response message for the random access corresponding to the preamble, a radio remote control (RRC) connection being established based on the preamble and the response message; receiving configuration information, a repetition scheme based on time division multiplexing being set based on the configuration information; receiving downlink control information (DCI); and receiving a plurality of transmission occasions based on the DCI, wherein a resource allocation in the time domain for the first transmission occasion may be determined based on the time domain resource assignment field of the DCI, and resource allocation in the time domain for the second transmission occasion may be determined based on the resource allocation in the time domain for the first transmission occasion.
