Mechanisms for controlling sample rate and frequency shift of a digital signal in a multi-operator network. A method is performed by a network node. The method includes obtaining a frequency difference and a phase difference between two clock domains. One of the clock domains is associated with a radio access network of a network operator of the multi-operator network and the other of the clock domains is associated with a distributed antenna system in the multi-operator network. The method includes controlling sample rate conversion of the digital signal between the two clock domains using the phase difference. The digital signal is communicated between the radio access network and the distributed antenna system. The method includes controlling a frequency shift of the digital signal using the frequency difference.
