Abstract
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a terminal in a wireless communication system is provided. The method includes receiving, from a BS, RRC information configuring a plurality of TCI states for a PDSCH; receiving, from the BS, DCI indicating at least one TCI state from among the plurality of TCI states, wherein the at least one TCI state is associated with a CORESET pool index; and receiving the PDSCH based on the at least one TCI state.

A method performed by a terminal in a wireless communication system, the method comprising:
- receiving, from a base station (BS), radio resource control (RRC) information including information configuring a plurality of transmission configuration indicator (TCI) states for a physical downlink shared channel (PDSCH), information configuring a first control resource set (CORESET), and information configuring a second CORESET, wherein the information configuring the first CORESET includes a first CORESET pool index and the information configuring the second CORESET includes a second CORESET pool index;
- receiving, from the BS, a medium access control (MAC) control element (CE) activating at least one TCI state from among the plurality of TCI states, wherein the MAC CE includes a CORESET pool index field indicating that the at least one TCI state is associated with the first CORESET pool index;
- receiving, from the BS, downlink control information (DCI) indicating a TCI state from among the at least one TCI state, wherein the DCI is received based on the first CORESET;
- and
- receiving, from the BS, the PDSCH by applying the TCI state based on a beam application time, wherein the TCI state is associated with the first CORESET pool index.
