Advanced grant indicator and aperiodic tracking reference signal in discontinuous reception

An apparatus for wireless communication, comprising:

• a processor;
• a transceiver communicatively coupled to the at least one processor;
• and
• a memory communicatively coupled to the at least one processor,
• wherein the processor is configured to generate a transmission including:
• at least one grant indicator for at least one user equipment (UE) for a transmission, the at least one grant indicator configured to communicate a grant during a discontinuous reception (DRX) cycle to the at least one UE;
• a tracking reference signal (TRS) enabling at least one UE to update a tracking loop;
• and
• wherein the transceiver is configured to transmit the transmission to the at least one UE.

A non-transitory computer-readable medium storing computer-executable code, comprising code for causing a computer to:

• receive at least one grant indicator in a transmission from a base station in a wireless communication system, the indicator configured to notify the UE of the presence of a grant during a cycle of a discontinuous reception (DRX);
• receive a tracking reference signal (TRS) in the transmission usable by the at least one UE for updating a tracking loop;
• update the tracking loop;
• and
• process the received grant during the DRX cycle after the tracking loop is updated.
