This application describes methods and apparatus to allocate uplink (UL) power dynamically across multiple parallel radio frequency links for wireless devices. The wireless device sets an initial maximum transmit power level (MTPL) for each UL radio link of multiple radio links used for UL traffic based on a duty cycle prediction for the respective UL radio link. The wireless device adjusts the initial MTPL for each UL radio link based on a predicted data throughput for the UL radio link relative to a total predicted data throughput for all UL radio links. The adjusted MTPL for each UL radio link can be also reduced when the UL radio link uses UL multiple input multiple output (MIMO) transmission via multiple antenna ports, e.g., by apportioning the adjusted MTPL among the multiple antenna ports of the UL radio link equally.
