<p>The present invention relates to a method of automatic transmit power control (ATPC) in a N×N Multiple-Input Multiple-Output (MIMO) radio communication system. The ATPC method comprises estimating a received power of each radio, determining a propagation matrix comprising each radio path's attenuation between the transmitter radio unit and the receiver radio unit, determining total power corrections using the received power, the propagation matrix and a target receiver power, and applying the total power corrections to the transmitter radio units. The determining of the total power corrections further comprises determining an interference level at each receiver radio unit based on the received power and the propagation matrix, determining a power variation for the radio unit using the interference levels, and determining a power correction using the received power, the target receiver power and the propagation matrix. The power correction is applied to the transmitter radio units.</p> |
