A method for operating by a user equipment, UE, in a wireless communication system, the method comprising: receiving configuration information about a mode for transmitting a plurality of data generated based on same information; receiving downlink control information, DCI, including two transmission configuration indicator, TCI, states; receiving two physical downlink shared channels, PDSCHs, based on the configuration information and the DCI, wherein a first PDSCH of the two PDSCHs corresponds to a first TCI state of the two TCI states and a second PDSCH of the two PDSCHs corresponds to a second TCI state of the two TCI states, wherein, based on a unit of physical resource block, PRB, bundling being configured as a wideband: the first PDSCH is received in a first resource including half of consecutive PRBs among total PRBs allocated for the UE and the second PDSCH is received in a second resource including remaining PRBs excluding the first resource among the total PRBs, and wherein, based on the unit of the PRB bundling being configured as a 2 PRBs or 4 PRBs: the total PRBs allocated for the UE are divided into a plurality of precoding resource block groups, PRGs, the first PDSCH is received in a first resource including PRGs with even indexes among the plurality of PRGs, and the second PDSCH is received in a second resource including PRGs with odd indexes. receiving configuration information about a mode for transmitting a plurality of data generated based on same information; receiving downlink control information, DCI, including two transmission configuration indicator, TCI, states; receiving two physical downlink shared channels, PDSCHs, based on the configuration information and the DCI, wherein a first PDSCH of the two PDSCHs corresponds to a first TCI state of the two TCI states and a second PDSCH of the two PDSCHs corresponds to a second TCI state of the two TCI states, wherein, based on a unit of physical resource block, PRB, bundling being configured as a wideband: the first PDSCH is received in a first resource including half of consecutive PRBs among total PRBs allocated for the UE and the second PDSCH is received in a second resource including remaining PRBs excluding the first resource among the total PRBs, and the first PDSCH is received in a first resource including half of consecutive PRBs among total PRBs allocated for the UE and the second PDSCH is received in a second resource including remaining PRBs excluding the first resource among the total PRBs, and wherein, based on the unit of the PRB bundling being configured as a 2 PRBs or 4 PRBs: the total PRBs allocated for the UE are divided into a plurality of precoding resource block groups, PRGs, the first PDSCH is received in a first resource including PRGs with even indexes among the plurality of PRGs, and the second PDSCH is received in a second resource including PRGs with odd indexes. the total PRBs allocated for the UE are divided into a plurality of precoding resource block groups, PRGs, the first PDSCH is received in a first resource including PRGs with even indexes among the plurality of PRGs, and the second PDSCH is received in a second resource including PRGs with odd indexes.
