Abstract

The present invention provides a method for transmitting or receiving a data channel in a wireless communication system, and an apparatus therefor. Specifically, a method for receiving a data channel by user equipment (UE) in a wireless communication system may comprise the steps of: receiving downlink control information (DCI), wherein the DCI includes i) a transmission configuration indication (TCI) field and ii) an antenna port field; and receiving the data channel on the basis of the DCI, wherein multiple TCI states are indicated on the basis of the TCI field, a demodulation reference signal (DM-RS) port is indicated on the basis of the antenna port field, and a repetition scheme of the data channel is determined on the basis of the number of code division multiplexing (CDM) groups including a DM-RS port in which the data channel is received.

Description

technical field [0001] The present disclosure relates to a wireless communication system, and more particularly, to a method of transmitting or receiving a data channel based on a plurality of Transceiver Points (TRPs) to improve reliability and an apparatus supporting the same. Background technique [0002] Mobile communication systems have been developed to provide voice services while ensuring user mobility. However, in mobile communication systems, not only voice but also data services are expanding. Currently, there is a shortage of resources due to the explosive growth of services, and users demand higher-speed services. As a result, more advanced mobile communication systems are required. [0003] The requirements for next-generation mobile communication systems should be able to support the acceptance of explosive data traffic, a dramatic increase in data rate per user, a significant increase in the number of accepted connected devices, very low end-to-end delay, a...
