Abstract
The invention relates to a method and an arrangement in a transmitting node (560) for enabling a receiving node (540) to perform measurements on interference caused by transmissions from at least one transmission point (510, 520, 530) controlled by the transmitting node (560) on receptions at the receiving node (540). The transmitting and receiving nodes (560, 540) are comprised in a wireless communications system (500, 600, 700). The transmitting node determines (910) an interference measurement resource, IMR, comprising a set of Time-Frequency Resource Elements, TFREs, upon which the transmitting node is expected to transmit interference. The transmitting node then transmits (930) at least one interfering signal on said IMR as said interference. The at least one interfering signal comprises at least one of a desired signal, that is expected to be decoded or coherently measured upon by the receiving node (540) or another node (550) served by said transmitting node (560), and another signal, that is not expected to be decoded or coherently measured upon by any node (540, 550) served by said transmitting node (560). The desired signal is transmitted in place of the another signal as…
