    Abstract: A method for transmitting a data demodulation reference signal (DMRS) in a wireless communication system and a device therefor are disclosed. To this end, a basic DMRS is transmitted via the first OFDM symbol in a data transmission region of a predetermined subframe, and an additional DMRS is transmitted in the predetermined subframe in accordance with a level determined by a transmission environment, wherein the basic DMRS is characterized by being transmitted via the first OFDM symbol in the data transmission region of the predetermined subframe regardless of a transmission link, the structure of the subframe, and the transmission environment.

    Abstract: The present disclosure discloses a method of operating a terminal and a base station in a wireless communication system and an apparatus supporting same. According to an embodiment applicable to the present disclosure, a terminal may establish a connection with a base station on the basis of a synchronization signal/physical broadcast channel (SS/PBCH) block received from the base station. Then, the terminal is set to a transmission mode in which data generated from identical information is transmitted by the base station through a plurality of physical downlink shared channels (PDSCHs), and on the basis of the aforementioned, the terminal may obtain resource information through which the data is transmitted through the plurality of PDSCHs, and obtain related data information.

    Abstract: The present specification relates to a method for transmitting and receiving data by a base station in a wireless communication system. More specifically, a terminal receives configuration information for configuration of a control resource set (CORESET) from the base station. Thereafter, the terminal receives first downlink control information (DCI) and second DCI for generation of ACK/NACK by using a semi-static method on the basis of the configuration information. The terminal receives a first physical downlink shared channel (PDSCH) and a second PDSCH, and transmits first Ack/Nack for the first PDSCH and Ack/Nack for the second PDSCH, on a resource scheduled by the first DCI.
