Patent ID: 8140070

Claim:
A method of suppressing inter-cell interference in a wireless system, the method comprising: estimating, by a first radio equipped device in first cell, a set of estimated first channel coefficients based on signals received from a plurality of second radio equipped devices; estimating, by the first radio equipped device, a set of estimated second channel coefficients based on signals received from a plurality of third radio equipped devices in a second cell, generating, by the first radio equipped device, a precoding matrix based on the set of estimated first channel coefficients and the set of estimated second channel coefficients, the set of estimated first channel coefficients being associated with a set of first propagation channels between the plurality of second radio equipped devices in the first cell and a plurality of antennas at the first radio equipped device, and the set of estimated second channel coefficients being associated with a set of second propagation channels between the plurality of third radio equipped devices and the plurality at antennas of the first radio equipped device; and precoding, by the first radio equipped device, signals for transmission from the first radio equipped device to at least one second radio equipped device based on the precoding matrix.
