METHODS AND DEVICE FOR JOINT TRANSMISSION USING MULTIPLE ACCESS POINTS OVER WLAN NETWORKS Russian patent published in 2022 - IPC H04W84/12 H04W72/04 

FIELD: communication equipment.

SUBSTANCE: invention relates to communication. Receiving (1510) a first trigger frame from a first access point (AP) from a plurality of APs, wherein the first trigger frame includes first information; receiving (1520) a second trigger frame from a second AP of a plurality of APs after a predetermined period of time after receiving the first trigger frame, wherein the second trigger frame also includes first information of the first trigger frame; generating (1530) a synchronization frame based on the first trigger frame and the second trigger frame, wherein the synchronization frame includes synchronization information; transmitting a synchronization frame to at least a first AP and a second AP; and receiving (1540) data transmission based on the synchronization information from each of the first AP and the second AP.

EFFECT: enabling coordinated single-user (SU) downlink beamforming or access point (AP) joint precoding to synchronize with a station (STA), so that signals can reach STA with similar receiving power, moment of time and frequency and be properly decoded by STA.
