Abstract
Interference mitigation for a MU-MIMO wireless communication network includes determining a MU-MIMO group of further wireless stations to which respective beams are to be formed, forming a first beam for reception of transmitted data from a second wireless station based on previously determined channel estimates. When the MU-MIMO group has fewer members than a number of beams which a beamforming weights matrix is configured to receive, forming an additional beam(s) being offset in angle of arrival by a respective predetermined angle from the first beam for reception of the transmitted data from the second wireless station, and generating a decoded data stream from a data stream resulting from receipt of the transmitted data in the first beam and from respective data streams resulting from receipt of the transmitted data from the additional beam(s).
