Abstract (en)

[origin: WO2014117849A1] Receiver (120) and method (700) in a receiver (120), for interference cancellation of colliding reference signals received from network nodes (110, 130) comprised in a heterogeneous wireless network (100), especially but not limited to, a macro-pico scenario. The method (700) comprises detecting (701) colliding reference signals of a first network node (110) and a second network node (130). Further, the method (700) comprises performing (702) channel estimation by cancelling interference caused by the detected (701) colliding reference signals of the second network node (130), from the reference signals of the first network node (110), based on iterative application of a Space Alternating Generalised Expectation and maximisation "SAGE" algorithm.
