Default path loss reference signal in unified transmission configuration indication framework

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

• a memory;
• and
• one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
• receive, from a base station, downlink control information (DCI) scheduling an uplink transmission;
• determine a default path loss reference signal associated with the uplink transmission based at least in part on a repetition configuration associated with the DCI or information associated with a transmission configuration indication (TCI) state for an uplink control channel or an uplink reference signal;
• and
• perform an uplink power control operation for the uplink transmission using the default path loss reference signal.

A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:
• receive, from a base station, downlink control information (DCI) scheduling an uplink transmission;
• determine a default path loss reference signal associated with the uplink transmission based at least in part on a repetition configuration associated with the DCI or information associated with a transmission configuration indication state for an uplink control channel or an uplink reference signal;
• and
• perform an uplink power control operation for the uplink transmission using the default path loss reference signal.

An apparatus for wireless communication, comprising:

• means for receiving, from a base station, downlink control information (DCI) scheduling an uplink transmission;
• means for determining a default path loss reference signal associated with the uplink transmission based at least in part on a repetition configuration associated with the DCI or information associated with a transmission configuration indication state for an uplink control channel or an uplink reference signal;
• and
• means for performing an uplink power control operation for the uplink transmission using the default path loss reference signal.
