Abstract
A method is provided for reducing interferences in a wireless communication system. First, in one or more cells, a plurality of frequency-time frames are generated each having at least one predetermined frequency-time open window unused for desired wireless communications. The interference information is derived from the predetermined open windows of the frames. The interference for incoming signals is reduced by calculating beamforming weights using the observed interference information.
