1. A method of receiving, by a user equipment (UE), a physical downlink shared channel (PDSCH) in a wireless communication system, the method comprising:
receiving configuration information,
the configuration information including (i) first information for configuring semi-persistent downlink transmission and (ii) second information related to control resource sets (CORESETs),
the first information including multiple configurations related to downlink semi-persistent scheduling (SPS), and
(i) a first CORESET corresponding to a first CORESET group index and (ii) a second CORESET corresponding to a second CORESET group index being configured based on the second information;
receiving first downlink control information (DCI) with DCI format 1_0 based on the first CORESET and second DCI based on the second CORESET,
the semi-persistent downlink transmission being activated based on at least one of the first DCI with DCI format 1_0 or the second DCI; and
receiving a semi-persistent scheduling (SPS) PDSCH based on the activated semi-persistent downlink transmission,
wherein the SPS PDSCH is related to at least one of the first CORESET group index and second CORESET group index corresponding to at least one of the CORESET and the second CORESET which receives at least one of the first DCI and the second DCI by which the semi-persistent downlink transmission is activated,
wherein the semi-persistent downlink transmission assumes that a demodulation reference signal (DMRS) port other than the DMRS port received through the first DCI with DCI format 1_0 is not assigned to another UE, and
wherein the semi-persistent downlink transmission assumes that a Non-Coherent Joint Transmission (NCJT) is not performed on the symbol in which in the SPS PDSCH scheduled by the first DCI with DCI format 1_0 is transmitted.
