Abstract: Systems, methods, apparatuses, and computer program products for determining transmit weights are provided. One method includes selecting users to pair for multi-user multiple input multiple output transmission, calculating multi-user multiple input multiple output (MU-MIMO) transmit weights in a communication system employing an analog electrically steered array with Q antennas, applying the multi-user multiple input multiple output weights to the transmitted signals, and transmitting the weighted signals from an antenna array. The calculating may include calculating the MU-MIMO transmit weights so that a sum of power across a same element of the selected users' weight vectors is equal on all of the antennas and one of either sum throughput across users or sum signal to interference plus noise ratio (SINR) across users is maximized.
