Abstract: Methods in a multiple-cell cellular network that implements iterative coordinated beamforming (I-CBF) algorithms with limited cooperation from adjacent nodes (base stations and/or mobile stations) may jointly determine transmit beamforming vectors and receive combining vectors to increase sum throughput. The transmit beamforming vectors and receive combining vectors can be determined based on a performance metric, such as by maximizing SINR (signal-to-interference-and-noise ratio) for each mobile station in the network, maximizing SLNR (signal-to-leakage-and-noise ratio) for each base station in the network, or minimizing SMSE (sum mean square error). The algorithms may be performed to update vectors synchronously. In other cases, the algorithms may be performed to update vectors asynchronously.
