Title:
METHOD FOR TRANSMITTING OR RECEIVING PHYSICAL DOWNLINK SHARED CHANNEL IN WIRELESS COMMUNICATION SYSTEM AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/222601
Kind Code:
A1
Abstract:
The present invention provides a method for transmitting or receiving a physical downlink shared channel (PDSCH) in a wireless communication system, and a device therefor. Specifically, a method for receiving a PDSCH by a user equipment (UE) in a wireless communication system may comprise the steps of: receiving downlink control information (DCI) which includes i) a transmission configuration indication (TCI) field and ii) an antenna port field; and receiving the PDSCH scheduled on the basis of the DCI, wherein: a plurality of TCI states is indicated on the basis of the TCI field; demodulation reference signal (DM-RS) ports of a plurality of code division multiplexing (CDM) groups are indicated on the basis the antenna port field; and a first TCI state among the plurality of TCI states corresponds to a CDM group including a first DM-RS port that is based on an indication order of the DM-RS ports.
