Apparatuses, methods, and systems are disclosed for determining a maximum power reduction for non-contiguous radio resource allocations. One apparatus includes a processor that receives a non-contiguous resource allocation and calculates a fraction of resource block punctured from a smallest containing contiguous allocation (“SCCA”). Here, the SCCA is a smallest set of contiguous resource blocks that encompasses the non-contiguous resource allocation. The processor determines a first additional maximum power reduction for the non-contiguous resource allocation in response to the fraction of punctured resource blocks being less than a threshold value. The apparatus includes a transceiver that transmits an uplink signal on the non-contiguous resource allocation using the first additional maximum power reduction in response to the fraction of punctured resource blocks being less than the threshold value.
