Two-stage uplink grant scheduling with discontinuous reception (drx)

A user equipment (UE) comprising:

• a memory;
• a transceiver;
• and
• at least one processor coupled to the memory and the transceiver, wherein the UE is configured to:
• receive, from a base station (BS), a first downlink control information (DCI) message scheduling an uplink (UL) data transmission, the first DCI message indicating a first value for an UL schedule timing indicator;
• activate a timer based at least in part on the first value of the UL schedule timing indicator;
• monitor a downlink control channel based at least in part on the timer;
• and
• receive, from the BS, a second DCI message indicating UL schedule timing for the UL data transmission based at least in part on the monitoring.

A non-transitory computer-readable medium having program code recorded thereon for wireless communication by a user equipment (UE), the program code comprising:

• code for causing the UE to receive, from a base station (BS), a first downlink control information (DCI) message scheduling an uplink (UL) data transmission, the first DCI message indicating a first value for an UL schedule timing indicator;
• code for causing the UE to activate a timer based at least in part on the first value of the UL schedule timing indicator;
• code for causing the UE to monitor a downlink control channel based at least in part on the timer;
• and
• code for causing the UE to receive, from the BS, a second DCI message indicating UL schedule timing for the UL data transmission based at least in part on the monitoring.
