1. A method performed by a wireless communication device for implicit Transmission Configuration Indicator, TCI, state activation, the method comprising:
sending a measurement report for one or more reference signals to a base station, the one or more reference signals being related to one or more TCI states, respectively;
activating at least one TCI state from among the one or more TCI states that are related to the one or more reference signals, a list of activated TCI states being configured for the wireless communication device, and a number, M, of entries in the list are reserved for implicit TCI state activation, the measurement report being a beam sweep report; and
a set of codepoints for a DCI field used for TCI state selection comprising a number, M, of codepoints that are reserved for implicitly activated TCI states and a number, N, of codepoints that are reserved for explicitly updated TCI states.
