1. A method performed by a terminal in a wireless communication system, the method comprising:
reporting, to a base station, information related to beam switching timing of the terminal;
receiving, from the base station, downlink control information (DCI) including information for triggering a channel state information-reference signal (CSI-RS) reception; and
performing the CSI-RS reception by applying a first quasi co-location (QCL) assumption based on a transmission configuration indicator (TCI) state for the CSI-RS or a second QCL assumption based on a TCI state for another downlink signal, based on the reported beam switching timing and a predetermined threshold,
wherein the predetermined threshold is based on a subcarrier spacing, and
wherein, based on a subcarrier spacing value being higher than a predetermined subcarrier spacing value, the predetermined threshold has a different value based on the subcarrier spacing.
