Dual band discontinuous reception

A method for wireless communication at a base station, comprising:

• configuring a first carrier and a second carrier for communications with a user equipment (UE);
• identifying data to transmit to the UE on the second carrier;
• transmitting wake-up signaling on the first carrier prior to an on-duration in a discontinuous reception (DRX) cycle used by the UE on the second carrier, the wake-up signaling indicating a presence of the data on the second carrier in the on-duration;
• and
• transmitting the data to the UE on the second carrier in the on-duration based at least in part on transmitting the wake-up signaling.

An apparatus for wireless communication at a user equipment (UE), comprising:

• means for monitoring a first carrier for wake-up signaling from a base station, the wake-up signaling being for a discontinuous reception (DRX) cycle on a second carrier;
• means for receiving wake-up signaling on the first carrier prior to an on-duration in the DRX cycle, the wake-up signaling indicating a presence of data on the second carrier in the on-duration;
• and
• means for waking up for the on-duration to receive the data on the second carrier based at least in part on receiving the wake-up signaling.
