摘要：
A base station transmits to a number of relay stations in a wireless network using a beamforming matrix. The beamforming matrix is generated by first obtaining a column vector from a beamforming matrix associated with each of the relay stations. An intermediate matrix is then generated using these column vectors. A zero-forcing procedure is then utilized to process the intermediate network to generate the final beamforming matrix.
