FIELD: radio engineering, communication.
SUBSTANCE: in one embodiment, the method at the point (AP) of the access to the station synchronization (STA), connected to the AP, includes sending, by AP, of the first control frame, that indicates the time interval, that is allocated for the STA, and sending the synchronization frame on the border of the time interval, allocated to the STA, if the AP determines, that the channel is not busy at the border of the time interval, allocated to the STA, and if the time interval, that is allocated for the STA, is longer than the first threshold value.
EFFECT: reduction of the stations power consumption and reduction of the network costs for the transmission of the synchronization frame by withdrawal from the synchronization frame transmission, when there is no need for this.
