Indication of predicted transmission configuration indicator states

An apparatus for wireless communications at a network entity, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• transmit, to a user equipment (UE), a first control signal indicating a first transmission configuration indicator (TCI) state for a first time domain window and a second TCI state for a second time domain window that is subsequent to the first time domain window, the second TCI state comprising a predicted TCI state;
• transmit a second control signal to the UE triggering activation of the first TCI state for communications during the first time domain window based at least in part on the first control signal;
• and
• communicate with the UE, according to the second control signal, using the second TCI state during the second time domain window based at least in part on the first control signal and an expiration of the first time domain window.

A method for wireless communications at a user equipment (UE), comprising:

• receiving a first control signal indicating a first transmission configuration indicator (TCI) state for a first time domain window and a second TCI state for a second time domain window that is subsequent to the first time domain window, the second TCI state comprising a predicted TCI state;
• receiving a second control signal triggering activation of the first TCI state for communications during the first time domain window based at least in part on the first control signal;
• and
• switching, according to the second control signal, to the second TCI state for communications during the second time domain window based at least in part on the first control signal and an expiration of the first time domain window.
