Abstract
An eNB is configured to perform a method for coordinating downlink power per layer at an eNB in a multiple-input, multiple-output (MIMO) network. The method includes receiving feedback from at least one UE; calculating a plurality of MIMO gradients based on the received feedback; changing a power per layer according to the calculated MIMO gradients; and exchanging gradient power information between the eNB and at least one neighboring eNB.
