Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support communications between a base station and a user equipment (UE) on multiple carriers. A UE may maintain a connection with a base station on a first carrier (e.g., an anchor carrier), and the UE may use a discontinuous reception (DRX) cycle on a second carrier. The DRX cycle may include scheduled on-durations during which the UE may monitor the second carrier for signaling from the base station. To reduce the power consumption at the UE associated with repeatedly monitoring scheduled on-durations, the base station may transmit wake-up signaling to the UE on the first carrier to identify the on-durations that include data from the base station. Accordingly, the UE may monitor these on-durations for the data and avoid monitoring other on-durations to limit power consumption.
