Title:
METHOD FOR TRANSMITTING AND RECEIVING DEMODULATION REFERENCE SIGNAL IN WIRELESS COMMUNICATION SYSTEM AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/222604
Kind Code:
A1
Abstract:
Disclosed are a method for transmitting and receiving a demodulation reference signal (DM-RS) in a wireless communication system and a device therefor. In detail, a method for receiving, by user equipment (UE), a DMRS in the wireless communication system comprises the steps of: receiving activation information; transmitting feedback information regarding the activation information; receiving downlink control information (DCI) comprising i) a transmission configuration indication (TCI) field and ii) an antenna port field; and receiving the DM-RS on the basis of the DCI, wherein the activation information comprises information associated with mapping of a code point and a TCI state of the TCI field, and, when the TCI field indicates a code point mapped to a plurality of TCI states and the antenna port field indicates antenna ports of a plurality of code division multiplexing (CDM) groups, a first TCI state of the plurality of TCI states can correspond to a CDM group associated with a first antenna port based on an indication order of the antenna ports.
