Abstract
A method performed by a user equipment (UE) in a wireless communication system includes receiving, from a base station (BS), physical downlink shared channel (PDSCH) configuration information including a list of transmission configuration indicator (TCI) states, receiving, from the BS, a PDSCH media access control element (MAC CE) including information indicating activation of at least one TCI state in the list, identifying whether the PDSCH MAC CE is a MAC CE capable of indicating two or more TCI states for one TCI codepoint, receiving, from the BS, downlink control information (DCI) including information indicating a TCI codepoint, and receiving, from the BS, data via a PDSCH based on the information indicating activation of the at least one TCI state, a result of the identifying, and the information indicating the TCI codepoint.
