SYSTEMS AND METHODS FOR REDUCTION OF ASCENDING COMMUNICATION LINE RESOURCES FOR PROVISION OF FEEDBACK BY CHANNEL CAPACITY FOR ADJUSTMENT OF MIMO CHANNEL DATA TRANSMISSION SPEEDS IN DESCENDING COMMUNICATION LINE Russian patent published in 2010 - IPC H04L1/00 

FIELD: information technologies.

SUBSTANCE: according to one version of realisation, method of wireless communication contains stages, at which each of data flow set is coded in compliance with according speeds of data transfer, data flows are shifted in set of MIMO channels in compliance with complete shifting of combinations, data flows exposed to shifting are transmitted, data flows exposed to shifting are received, decoded, and SNR is identified for each of data flows, SNR combined metrics is calculated for a set of data flow, combined metrics is provided as a feedback, a set of separate SNR metrics is identified on the basis of combined SNR metrics, and speeds of data transmission are adjusted, at which data flows are coded, on the basis of separate SNR metrics.

EFFECT: improved efficiency of the system as a result of reduced volume of ascending communication line resources required for provision of feedback by channel efficiency, for adjustment of data transmission speeds in channels MIMO in descending communication line.
