An apparatus, computer program, and method are provided for setting a power of a cell node based on cell node gradient information. Cell node gradient information is generated based on a multiple-codeword channel quality indicator (CQI), utilizing a multiple-input-multiple-output (MIMO)-capable cell node in a network configured for communicating with a plurality of MIMO-capable user equipment. Additionally, other cell node gradient information is received that is generated for a plurality of other MIMO-capable cell nodes. The generated cell node gradient information and the other cell node gradient information are processed. Further, a power of the MIMO-capable cell node is set, based on the processing.
