Claim 10:
11. A system for performing channel estimation in a multiple input multiple output (MIMO) based cellular radio technology, the system comprising:
one or more UEs; and
a node configured to wirelessly communicate with the one or more UEs, wherein each of the one or more UEs and/or the node are configured to:
(1) receive a port-specific received power level for each antenna element of a plurality of antenna elements;
(2) compare 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 transmitting antenna element; and
(3) based on the comparing, dynamically tuning the port-specific transmitted power level of the corresponding transmitting antenna element, wherein dynamically tuning the port-specific transmitted power level of the corresponding transmitting antenna element comprises: incrementally increasing the port-specific transmitted power level of the corresponding transmitting antenna element if the comparing indicates a ratio of the port-specific received power level of the antenna element of the plurality of antenna elements is above a threshold; or incrementally decreasing the port-specific transmitted power level of the corresponding transmitting antenna element if the comparing indicates a ratio of the port-specific received power level of the antenna element of the plurality of antenna elements is below a threshold.
