Abstract

Methods, systems, and devices for wireless communications are described. Multiple component carriers may be configured for communications between communication devices, where uplink data channel resources may be scheduled on a component carrier of the component carriers. A communication device may report, over the uplink data channel resources to another communication device, a first report for available transmission power for uplink data transmissions over the component carrier and a second report associated with available transmission power for uplink control transmissions over a second component carrier. The other communication device may use the second report to determine the available transmission power for uplink control transmissions over the second component carrier. The other communication device may schedule communication resources based on the determined available transmission power for uplink control transmissions.
