Method for transmitting and receiving downlink data in wireless communication system, and apparatus therefor

A user equipment (UE) configured to receive downlink data in a wireless communication system, the UE comprising:

• at least one transceiver;
• at least one processor;
• and
• at least one computer memory connected to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
• receiving configuration information including a plurality of QCL(quasi-co-location) related information;
• receiving downlink control information(DCI) including information indicating at least two of the plurality of QCL related information,
• wherein a first QCL related information and a second QCL related information are indicated based on the DCI;
• and
• receiving downlink data on a plurality of resources ,
• wherein the plurality of resources comprise a first resources and a second resources that are non-overlapping in the frequency domain, and
• wherein the first QCL related information is associated to the first resources and the second QCL related information is associated to the second resources.

A method for transmitting downlink data in a wireless communication system, the method performed by a base station (BS) comprising:

• transmitting, to a user equipment (UE), configuration information including a plurality of QCL(quasi-co-location) related information;
• transmitting, to the UE, downlink control information(DCI) including information indicating at least two of the plurality of QCL related information;
• and
• transmitting, to the UE, downlink data on a plurality of resources ,
• wherein the plurality of resources comprise a first resources and a second resources that are non-overlapping in the frequency domain, and
• wherein based on a first QCL related information and a second QCL related information being indicated by the information, the first QCL related information is associated to the first resources and the second QCL related information is associated to the second resources.
