Abstract
Methods, systems, and devices for wireless communications are described for uplink carrier aggregation in which uplink control channel communications may be transmitted on a primary component carrier (CC) and one or more secondary CCs. Uplink transmission power control for the control channel communications may be determined based on a power control configuration provided by a base station. The primary CC and secondary CC(s) may use a same set of power control parameters based on being within a same frequency band, and may use different power control parameters when one or more of the CCs are in a different frequency bands. Power control commands to increase or decrease transmit power may be accumulated on a per-CC basis, or across multiple CCs, based at least in part on the power control configuration.
