Title: Spatial puncturing apparatus, method, and system

Abstract: Stations in an N.times.N multiple-input-multiple-output (MIMO) wireless network always puncture the weakest spatial channel. A receiving station determines channel state information for N spatial channels and feeds back to the transmitting station channel state information for only N-1 spatial channels. The channel state information may include a beamforming matrix to cause the transmitting station to utilize N-1 spatial channels.
