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.

Abstract: A method and apparatus may include determining that a triggering has occurred. The triggering corresponds to a triggering of a formation of a multiple-input and multiple-output arrangement. The multiple-input and multiple-output arrangement comprises a grouping of user antennas and an antenna of the apparatus, and the apparatus is located at an existing infrastructure. The method may also include receiving data traffic information. The data traffic information comprises information that indicates an amount of data traffic that is requested by users of the user antennas. The method may also include forming the multiple-input and multiple-output arrangement based on the received data traffic information.
