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.

Abstract: According to an embodiment of the present invention a user equipment (UE) may receive, in a first search space set, first downlink control information (DCI) that schedules a first physical downlink control channel (PDSCH) based on a first transmission configuration index (TCI) value and receive, in a second search space set of the plurality of search space sets, second DCI that schedules a second PDSCH based on a second TCI value. The UE may determine that a transport block (TB) in the second PDSCH is re-transmission of a TB in the first PDSCH, based on that the first DCI and the second DCI indicates a same hybrid automatic repeat request (HARQ) process identifier (ID), and the first DCI and the second DCI indicates a same new data indicator (NDI) value, even if the first TCI value associated with the first PDSCH is different from the second TCI value associated with the second PDSCH.
