1. A method performed by a first network node, the method comprising:
determining a power backoff indicator, PBI, for a first user equipment, UE, based on at least one of channel conditions of the first UE and channel conditions of a second UE, data reliability requirements of the second UE, and data performance of the first UE;
estimating an amount of interference reduction needed for second data to be received from the UE fulfilling a requirement, the PBI being determined based on the estimated amount of interference reduction;
transmitting the PBI toward the first UE; and
receiving second data from the first UE, transmission of the second data having been adjusted based on the PBI.
