Abstract
Radio network node and method therein, for channel estimation of a channel used for wireless signal communication with a UE. The radio network node comprises a multiple antenna array configured for beamforming, spatial multiplexing and MIMO transmission. The radio network node also comprises a receiver, configured for receiving a first pilot signal from the UE, and a wireless signal from an interferer; and also configured for receiving a second pilot signal from the UE at a determined AoA, filtered by a receiver pre-filter; and a processor configured for spatial analyzing the received signals; and selecting the UE pilot signals; and configured for determining AoA for the selected pilot signals; and furthermore configured for designing a receiver pre-filter, for isolating signals from the AoA; and also further configured for estimating the channel, based on the received second pilot signal.
