SYSTEMS AND METHODS TO REDUCE RESOURCES OF DOWNLINK FOR PROVISION OF FEEDBACK BY EFFICIENCY OF CHANNEL FOR ADJUSTMENT OF SPEEDS OF DATA TRANSFER OF MIMO CHANNEL OF DOWNLINK

摘要

FIELD: radio, communication.;SUBSTANCE: each flow of data flows set is coded according to appropriate speeds of data transfer, they perform shifts of data flows on the set of MIMO channels according to full shift of combinations, they transfer data flows subjected to shifting, decode and determine SNR for each of data flows, they calculate a summary metric SNR for the set of data flows, they provide a summary metric as a feedback, they determine a set of separate metrics SNR for data flows on the basis of the summary metric SNR, and speeds of data transfer are adjusted, on which data flows are coded, on the basis of separate metrics SNR.;EFFECT: increased efficiency of MIMO wireless communication system due to reduction of a volume of downlink resources, necessary for provision of feedback by efficiency of a channel, for adjustment of data transfer speeds on MIMO channels.;17 cl, 8 dwg
