Abstract
Techniques are described for wireless communication. A first method includes identifying a first uplink component carrier of a plurality of component carriers configured for a user equipment (UE); determining that the first uplink component carrier is transmitted over a shared radio frequency spectrum band; and performing a power management operation on the first uplink component carrier, for a current subframe, based at least in part on the determining.
Claims16
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.
