1. A method of receiving a downlink channel by a terminal in a wireless communication system, the method comprising:
receiving configuration information associated with downlink channel repeat transmission; and
repetitively receiving a downlink control channel including same downlink control information (DCI) from one or more TRPs (transmission reception point), wherein the DCI indicates one or more of a number of CDM groups or the number of repetitions for a downlink data channel; and
based on the DCI not including TCI (Transmission Configuration Indicator) information, based on one or more of the configuration information, the number of CDM groups, or the number of repetitions for the downlink data channel, receiving the downlink data channel from a single TRP (STRP) or multiple TRPs (MTRPs) of the one or more TRPs.
