Abstract

A method for allocating power for beamforming is described. The method includes selecting a number of data streams to be employed. Power for beamforming is allocated to the selected number of data streams based upon the effective SINR and in consideration of a FEC code. The allocation of power may be based upon maximizing the effective SINR. Additionally, the method may include determining an effective SINR using an EESM procedure. An apparatus, computer readable medium and system are also described.
