Abstract
A method and network node for virtual beam sweeping of signals received by antennas of the network node are provided. According to one aspect, a method includes determining elements of abeam forming matrix W. The method further includes determining elements of a virtual beam sweeping matrix V, the elements of the virtual beam sweeping matrix V being determined to form beams between beams formed by the beam forming matrix W. The method also includes applying the matrices V and W to uplink signals Sa received by antennas of the network node to produce received signals Sb in a beam space.
