Disclosed are a method and apparatus for transmitting or receiving a downlink channel from multiple transmission/reception points in a wireless communication system. A method for receiving a downlink channel by a terminal in a wireless communication system, according to one embodiment of the present disclosure, comprises the steps of: receiving configuration information associated with repetitive transmission of a downlink channel; repetitively receiving a downlink control channel including the same downlink control information (DCI) from one or more transmission/reception points (TRPs), wherein the DCI indicates at least one from among the number of code division multiplexing (CDM) groups and the number of repetitions for a downlink data channel; and receiving, on the basis of the DCI not including transmission configuration indicator (TCI) information, a downlink data channel from a single TRP (STRP) or multiple TRP (MTRP) from among the one or more TRPs on the basis of one or more from among the configuration information, the number of CDM groups, and the number of repetitions for the downlink data channel.
