Abstract  Abstract

SYSTEMS and methods FOR LURING THE UPLINK RESOURCES FOR PROVIDING THE PERFORMANCE OF CHANNEL feedback FOR THE ADJUSTMENT OF DATA RATES THE MIMO CHANNEL OF DOWNLINK. Systems and methods for improving the performance of one system of MIMO wireless communication by means of reducing the amount of uplink resources that are needed to provide feedback for the performance of channel for adjusting the rate of the MIMO channel data in the downlink. In one embodiment one method comprises encodificar each one among one set of the flows of data according with the corresponding data rates; the exchange of data flows in one set of MIMO channels of according with a full permutation of combinations; transmitting the flows of data; receiving the flows of data; decoding and determining a SNR for each one of the data flows; computing a metric of SNR derivatives for the set of the data flows; providing the condensed metric as feedback; determining one set of metrics of SNR for individual flows of data with the base in the SNR condensed metric; and adjust the rates of data in which the streams of data are encodificados with base metrics in a SNR individual.
