METHOD, ACCESS POINT AND STATION FOR TRANSMITTING CHANNEL STATE INFORMATION Russian patent published in 2019 - IPC H04W24/00 

FIELD: wireless communication equipment.

SUBSTANCE: invention relates to wireless communication. Method for transmitting channel state information (CSI) includes: receiving by a station a feedback indication message, highly effective long training sequence and resource scheduling message sent by an access point; when determining that the station belongs to target stations, returning an acknowledgment message to the access point using a communication resource indicated by the resource scheduling message. Feedback indication message is used to indicate at least two target STAs to which should return the AP to CSI information. Highly effective long training sequence is used to determine the CSI information of the STA. Acknowledgment message is returned to the access point.

EFFECT: technical result is the increased efficiency of CSI information transmission.
