Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). Inter-cell coordinated transmission through a multi-transmission reception point (multi-TRP) in a wireless or communication system is described. A terminal receives configuration information related to a multi-TRP, checks whether inter-cell multi-TRP transmission is configured on the basis of the configuration information, based on the inter-cell multi-TRP transmission being configured, checks a control resource set (CORESET) for the multi-TRP on the basis of the configuration information, receives downlink control information (DCI) for the multi-TRP through the CORESET, and receives data from the multi-TRP on the basis of the DCI.
