METHOD OF MULTI-USER UPLINK TRANSMISSION IN WIRELESS NETWORK SYSTEM AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2018 - IPC H04L5/00 

FIELD: wireless communication equipment.

SUBSTANCE: invention relates to wireless communication and can be used when performing multi-user transmission on an uplink. Method for the STA for transmitting uplink data based on multi-user (MU) uplink (UL) transmission in a wireless network (WLAN) system is transmitting a buffer status report (BSR) to an access point (AP), to help AP determine the information about MU scheduling for UL, receiving from the AP to which the indicated STA is associated, a frame including MU scheduling information for the UL for uplink data transmission and transmitting the uplink data to the AP based on the MU scheduling information for the UL, the uplink data transmission being performed after the SIFS (short interframe spacing) after receiving the frame including the MU scheduling information for the UL, said frame further includes a field including the null information, to provide additional time for the STA to prepare uplink data transmission, and field including zero information, is attached to the end of the MU scheduling information for the UL, and the null information includes a binary value that identifies the end of the MU scheduling information for the UL.

EFFECT: increased efficiency of data transmission.
