METHOD AND DEVICE FOR ENABLING STATION TO RECEIVE SIGNAL IN WIRELESS COMMUNICATION SYSTEM Russian patent published in 2018 - IPC H04L29/08 

FIELD: electrical communication engineering.

SUBSTANCE: invention relates generally to a wireless communication system. Method of receiving a signal includes a step of receiving a PPDU, which includes a MAC frame decoding the MAC frame, and verifying information in the MAC frame based on the MAC header of the MAC frame, which includes a first address field and a second address field. STA identifier subfield is the identifier subfield (AID) of the receiver association or the transmitter AID subfield according to the UL / DL direction indicated by the UL / DL indication subfield, wherein when receiving a DL PPDU, in which the UL/DL indication subfield indicates the direction of the DL, the STA determines that the STA ID subfield is the receiver AID subfield, when transmitting a UL PPDU in which the UL / DL indication subfield indicates the UL direction, the STA determines that the STA ID subfield is the transmitter AID subfield instead of the receiver AID subfield.

EFFECT: technical result of the invention is high efficiency of using radio resources by preventing the transmission of redundant information and thereby preventing unnecessary expenditure of resources in a wireless communication system.
