1. A method, carried out in a radio network node, for configuring uplink output power of radio transmission from a radio terminal, said method comprising:
determining a demand power reduction based on a maximum power level associated with a first uplink duty cycle;
transmitting, to a radio network node, an indication of the demand power reduction; and
receiving, from the network node, an indication of an actual uplink duty cycle and of a target power reduction associated with the actual uplink duty cycle;
wherein the receiving comprises receiving, from the network node, network scheduling for an uplink transmission of the radio terminal in accordance with the actual uplink duty cycle; and
configuring the output power based on the target power reduction.
