A multi-beam polling based transmission method and apparatus, and a communications device and an electronic device readable storage medium based on the method are disclosed. An access point AP broadcasts a beacon message, where the beacon message is used to indicate duration of a beacon period; and sends a data packet that includes channel use duration to a station STA, where the channel use duration is used to indicate a target slot at which the AP communicates with the STA within a duration range of the beacon period, so that the AP can communicate with the STA at the target slot.
