Abstract: Methods, systems, and devices for wireless communications are described for uplink transmit power determination in which a user equipment (UE) may be configured for carrier aggregation of multiple concurrent uplink component carrier (CC) transmissions. The UE may apply an adjustment to a maximum transmit power limit (MTPL) for one or more CCs when the UE is configured for uplink carrier aggregation. The MTPL adjustment may be applied to reduce a transmit power of one of the CCs when a maximum transmit power is requested for the CC. The MTPL adjustment may reduce the transmit power to be less than the MTPL of the UE and thereby provide that one or more other CCs may still have some transmission power. The UE may compute a MTPL adjustment based on a static value or on a per-subframe basis based on scheduling parameters and a requested transmit power for each CC.
