Efficient power utilization for enhanced component carriers

A method for wireless communication, comprising:

• determining to transmit a data transmission via a second bandwidth of downlink resources that is associated with a second subcarrier spacing different than the first subcarrier spacing;
• transmitting, in a first bandwidth of downlink resources that is associated with a first subcarrier spacing, a control message that includes a grant for a wireless device indicating the second bandwidth of downlink resources based at least in part on determining to transmit the data transmission via the second bandwidth of downlink resources;
• scheduling a time gap between the control message and the data transmission based at least in part on the control message;
• and
• transmitting, in the second bandwidth, the data transmission during a transmission time interval (TTI) based at least in part on the time gap.

An apparatus for wireless communication, in a system comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory, the instructions being executable by the processor to:
• monitor a first bandwidth of downlink resources at a wireless device, the first bandwidth associated with a first subcarrier spacing;
• receive a control message that includes a grant indicating a second bandwidth of downlink resources associated with a data transmission, the second bandwidth associated with a second subcarrier spacing different than the first subcarrier spacing;
• determine to monitor the second bandwidth based at least in part on receiving the grant that indicates the second bandwidth;
• and
• monitor the second bandwidth for the data transmission during a transmission time interval (TTI) based at least in part on determining to monitor second bandwidth, wherein a time gap exists between the control message and the data transmission.
