Claim:
1. A method in a transmitting node for enabling a receiving node to perform measurements on interference caused by transmissions from at least one transmission point controlled by the transmitting node on receptions at the receiving node, the transmitting and receiving nodes being comprised in a wireless communications system, the method CHARACTERIZED IN comprising: determining an interference measurement resource, IMR, comprising a set of Time-Frequency Resource Elements, TFREs, upon which the transmitting node is expected to transmit interference; and transmitting at least one interfering signal on said IMR as said interference, wherein the at least one interfering signal comprises of a desired signal, that is expected to be decoded or coherently measured upon by the receiving node or another node served by said transmitting node, and another signal, that is not expected to be decoded or coherently measured upon by any node served by said transmitting node, wherein the desired signal is transmitted in place of the another signal as said at least one interfering signal on one or more TFREs of the IMR when the at least one transmission point is to transmit the desired signal to the receiving node or to the another node served by said transmitting node and wherein the another signal is transmitted on TFREs of said IMR where no desired signal is transmitted and wherein the another signal is muted on TFRE's of said IMR where the desired signal is transmitted.
