Full duplex TCI indication under unified TCI framework

A user equipment (UE) for wireless communication, comprising:

• a memory storing computer-executable instructions;
• and
• at least one processor coupled with the memory and configured to execute the computer-executable instructions to:
• receive, from a base station, a plurality of transmission configuration indication (TCI) states, the plurality of TCI states including a full duplex TCI state corresponding to at least two channels for a first transmission link type and at least one channel for a second transmission link type;
• receive, within downlink control information (DCI), an indication including an indication identifier that identifies the full duplex TCI state;
• transmit an acknowledgment to the DCI;
• determine an application time by adding a predefined amount of slots or time from an end of the acknowledgment to the DCI;
• and
• apply the full duplex TCI state in accordance with the indication identifier and the determined application time.

A method of wireless communication at a base station, the method comprising:

• transmitting, to a user equipment (UE), a plurality of transmission configuration indication (TCI) states, the plurality of TCI states including a full duplex TCI state corresponding to at least two channels for a first transmission link type and at least one channel for a second transmission link type;
• transmitting to the UE, within downlink control information (DCI), an indication including an indication identifier that identifies the full duplex TCI state;
• receiving an acknowledgment to the DCI from the UE;
• determining an application time by adding a predefined amount of slots or time from an end of the acknowledgment to the DCI;
• transmitting, to the UE, a reference signal to be measured by the UE to determine channel information for the at least two channels and the at least one channel based on the full duplex TCI state;
• and
• applying the full duplex TCI state for full duplex communications with the UE in accordance with the indication identifier and the determined application time.
