METHOD AND DEVICE FOR TRANSFER OF DATA FROM WIRELESS LOCAL NETWORK TO PLURALITY OF STATIONS Russian patent published in 2017 - IPC H04J11/00 

FIELD: information technology.

SUBSTANCE: method comprises: a step in which the access point AP generates PPDU protocol data in MIMO-OFDMA format; and a step in which AP transmits PPDU in MIMO-OFDMA format to a plurality of STAs, wherein PPDU in MIMO-OFDMA format comprises a plurality of PPDUs in sub-channel format that are time-synchronized, and a plurality of PPDUs in sub-channel format are transmitted respectively to the plurality of STAs through the plurality of the respective sub-channel frequency bands, and the number of learning fields for MIMO transmission that are included in the corresponding plurality of PPDUs in sub-channel format may be identical.

EFFECT: increasing the bandwidth of channels.
