Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently performing dynamic power control with minimal complexity in a dual connectivity mode. In particular, a user equipment (UE) may determine the reserved power (or maximum available power) for uplink transmissions on one or more cells in one cell group to a base station based on the total power available to the UE and the minimum reserved power for uplink transmissions on one or more cells in another cell group. Once the UE determines the reserved power for conflicting uplink transmissions on one or more cells in a cell group, the UE may allocate the reserved power to each uplink transmission on the one or more cells in the cell group (e.g., based on a priority of each of the uplink transmissions).
