Single downlink control information based activation command for transmission configuration indication state

An apparatus comprising:

• at least one processor;
• and
• at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to:
• receive, from a network device, an activation command for a transmission configuration indication (TCI) codepoint, the TCI codepoint indicating whether a TCI state for a certain TCI codepoint indicates a first joint TCI state and whether a second joint TCI state associated with the certain TCI codepoint is present;
• and
• determine, based on the activation command, that a joint TCI state of the certain TCI codepoint indicates at least one of the first joint TCI state and the second joint TCI state.
