FIELD: wireless communication equipment.
SUBSTANCE: invention relates to wireless communication. Method of communication comprises steps of: performing, by an access point, a request to send (RTS) frame on a first frequency band, the first frequency band including at least a first channel and a second channel; receiving, by an access point, a clear to send (CTS) frame, only on a first channel of a first frequency band, from a first station in response to a RTS frame; through an access point, based on receiving a CTS frame from a first station, acknowledging that interaction of RTS/CTS frames is successful; after acknowledgment, a trigger frame is sent, by access point, on first channel and on second channel of first frequency band, respectively, to first station and second station (503, 505); wherein the trigger frame is used to schedule the first station and the second station to send uplink data.
EFFECT: increased efficiency of data transmission.
