Abstract
A wireless communication system configured for providing wireless communication is adapted to provide a first radio channel in a radio propagation channel and in a first frequency interval and to provide a second radio channel in the radio propagation channel and in a second frequency interval differing from the first frequency interval. The wireless communication system is to obtain first radio channel information indicating a behaviour of the first radio channel and to manage beamforming for the second radio channel based on the first radio channel information.
