1. A method performed by a terminal in a wireless communication system, the method comprising:
obtaining, from a base station, first information on transmission configuration indicator (TCI) states including a first TCI state associated with a first transmission and reception point (TRP) and a second TCI state associated with a second TRP and second information on a single frequency network (SFN) transmission scheme;
identifying downlink reference signals of the first TCI state and the second TCI state based on the first information; and
according to the second information, receiving, from the base station, a downlink channel based on an assumption that at least one demodulation reference signal (DM-RS) port of the downlink channel is quasi co-located with the downlink reference signals of the first TCI state and the second TCI,
wherein a Doppler shift related quasi co-location parameter of the second TCI state is excluded from quasi co-location parameters for the assumption.
