1. An apparatus for wireless communication, comprising:
a processor; and
memory coupled with the processor,
the processor and the memory configured to:
receive scheduling of an uplink transmission of multiple subframes associated with a channel of an unlicensed radio frequency spectrum band;
perform a clear channel assessment (CCA) associated with the channel of the unlicensed radio frequency spectrum band based at least in part on the received scheduling; and
transmit the uplink transmission, based at least in part on a successful performing of the CCA associated with the channel of the unlicensed radio frequency spectrum band, in accordance with a power management operation, the power management operation including:
reducing a transmit power of a first subframe of the uplink transmission of the multiple subframes; and
carrying over the reduced transmit power to at least one subframe of the multiple subframes of the uplink transmission following the first subframe.
