6. The method of claim 5 , wherein, within the entire frequency resource allocated to the UE, the first frequency resource is configured in even-numbered precoding resource groups, and the second frequency resource is configured in odd-numbered precoding resource groups.
7. A user equipment (UE) configured to receive a physical downlink shared channel (PDSCH) in a wireless communication system, the UE comprising:
at least one transceiver;
at least one processor; and
at least one computer memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
receiving a downlink control information (DCI) message for scheduling the PDSCH, the DCI message including information related to a first transmission configuration indication (TCI)-related information and a second TCI-related information, and
receiving a first PDSCH and a second PDSCH based on the configuration information and the DCI message,
wherein based on a predefined rule, a first frequency resource for the first PDSCH is configured based on the first TCI-related information, and a second frequency resource for the second PDSCH is configured based on the second TCI-related information, wherein the first frequency resource is different from the second frequency resource, and
wherein a transport block size related to the first PDSCH and the second PDSCH is determined based on the first frequency resource.
8. The UE of claim 7 , wherein the first TCI-related information is information to which a first index is mapped among pieces of TCI-related information configured for the UE.
9. The UE of claim 7 , wherein the operations further include receiving configuration information for the first TCI-related information and the second TCI-related information through higher layer signaling, and
the first TCI-related information is associated with a first transmission unit for transmitting the first PDSCH, and the second TCI-related information is associated with a second transmission unit for transmitting the second PDSCH.
10. The UE of claim 7 , wherein, based on the predefined rule determined as precoding information configured to a wideband precoding resource, the first frequency resource is configured as a first half of an entire frequency resource allocated to the UE, and the second frequency resource is configured as a remaining half of the entire frequency resource.
11. The UE of claim 7 , wherein, based on the predefined rule determined as precoding information configured to one of (i) a precoding resource group configured to size 2 or (ii) a precoding resource group configured to size 4, the first frequency resource and the second frequency resource are configured to cross each other in units of precoding resource groups.
12. The UE of claim 11 , wherein, within the entire frequency resource allocated to the UE, the first frequency resource is configured in even-numbered precoding resource groups, and the second frequency resource is configured in odd-numbered precoding resource groups.
