Claim 0:
1. A method for performing channel estimation in a multiple input multiple output (MIMO) based cellular radio technology, the method comprising:
receiving, at a node configured to wirelessly communicate with one or more UEs, a port-specific received power level for each antenna element of a plurality of antenna elements of a UE of the one or more UEs;
comparing, at the node, the port-specific received power level of an antenna element of the plurality of antenna elements to a port-specific transmitted power level of a corresponding node antenna element, wherein the comparing indicates a ratio of the port-specific received power level of an antenna element of the plurality of antenna elements to the port-specific transmitted power level of a corresponding node antenna element is below a threshold; and
based on the comparing, dynamically tuning, at the node, the port-specific transmitted power level of the corresponding node antenna element.
