Techniques for indicating multiple tci states

A processor for wireless communication, comprising:

• at least one controller coupled with at least one memory and configured to cause the processor to:
• receive a first configuration message comprising an indication of one or more transmission configuration indicator (TCI) state sets, wherein each TCI state set of the one or more TCI state sets comprises one or more TCI states;
• receive a second configuration message comprising configuration information for scheduling a downlink channel or signal or an uplink channel or signal, wherein frequency resources that are allocated to a scheduled downlink channel or signal or a scheduled uplink channel or signal comprise a plurality of channel parts or signal parts, and wherein the second configuration message further comprises an indication of a plurality of TCI states associated with the plurality of channel parts or signal parts of the scheduled downlink channel or signal or the scheduled uplink channel or signal;
• and
• communicate in accordance with processing the plurality of channel parts or signal parts of the scheduled downlink channel or signal or the scheduled uplink channel or signal using the associated plurality of TCI states.

A method of a user equipment (UE), comprising:

• receiving a first configuration message comprising an indication of one or more transmission configuration indicator (TCI) state sets, wherein each TCI state set of the one or more TCI state sets comprises one or more TCI states;
• receiving a second configuration message comprising configuration information for scheduling a downlink channel or signal or an uplink channel or signal, wherein frequency resources that are allocated to a scheduled downlink channel or signal or a scheduled uplink channel or signal comprise a plurality of channel parts or signal parts, and wherein the second configuration message further comprises an indication of a plurality of TCI states associated with the plurality of channel parts or signal parts of the scheduled downlink channel or signal or the scheduled uplink channel or signal;
• and
• communicating in accordance with processing the plurality of channel parts or signal parts of the scheduled downlink channel or signal or the scheduled uplink channel or signal using the associated plurality of TCI states.

A network equipment (NE) for wireless communication, comprising:

• at least one memory;
• and
• at least one processor coupled with the at least one memory and configured to cause the NE to:
• determine one or more transmission configuration indicator (TCI) state sets comprising one or more TCI states;
• transmit a first configuration message comprising an indication of the one or more TCI state sets;
• determine information for scheduling a downlink channel or signal or an uplink channel or signal, wherein frequency resources that are allocated to the scheduled downlink channel or signal or uplink channel or signal comprise a plurality of channel parts or signal parts;
• determine a plurality of TCI states associated with the plurality of channel parts or signal parts of the scheduled downlink channel or signal or uplink channel or signal;
• and
• transmit a second configuration message comprising the information for scheduling the downlink channel or signal or uplink channel or signal and an indication of the plurality of TCI states associated with the plurality of channel parts or signal parts.
