1. A method for wireless communication at a user equipment (UE), comprising:
receiving scheduling information for a plurality of subframes;
determining, based at least in part on the scheduling information, one or more scheduling parameters for each of a plurality of component carriers used for uplink communications and a plurality of requested transmit powers associated with the plurality of component carriers;
calculating, at the UE for each subframe of the plurality of subframes based at least in part on the one or more scheduling parameters for each component carrier of the plurality of component carriers and the plurality of requested transmit powers associated with the plurality of component carriers, a power adjustment to a maximum transmit power limit for each of the plurality of component carriers, wherein:
a first power adjustment to the maximum transmit power limit for a first component carrier of the plurality of component carriers for a first subframe of the plurality of subframes is determined based at least in part on a second scheduling parameter and a second requested transmit power for a second component carrier for the first subframe,
a second power adjustment to the maximum transmit power limit for the second component carrier of the plurality of component carriers for the first subframe is based at least in part on a first scheduling parameter and a first requested transmit power for the first component carrier for the first subframe, and
a third power adjustment to the maximum transmit power limit for the first component carrier for a second subframe of the plurality of subframes is different than the first power adjustment to the maximum transmit power limit for the first component carrier; and
transmitting uplink communications in each subframe using one or more of the plurality of component carriers with a transmit power for each component carrier that is based at least in part on the calculated first power adjustment, second power adjustment, or third power adjustment.
