Abstract: This document discloses a solution for detecting interference in a radio access network. According to an aspect, a method includes as performed by a network node of the radio access network: acquiring a first equalized signal representing a signal received by a first radio head serving a terminal device, the first equalized signal including a signal received by the first radio head from the terminal device; acquiring a second equalized signal representing a signal received by a second radio head not serving the terminal device, wherein the second radio head is spatially distant from the first radio head; cross-correlating the first equalized signal with the second equalized signal and determining, on the basis of said cross-correlating, whether or not the second equalized signal also includes a signal received from the terminal device; and as a result of the second equalized signal being determined to include the signal received from the terminal device, causing execution of an interference management action.
