A scheduling method, including: listening to, by a station, a first beacon frame containing a DTIM message used for indicating a beacon interval allocated for each group of stations within a current scheduling period; determining the beacon interval allocated for the station within the current scheduling period according to the DTIM message contained in the first beacon frame; listening to, by the station, within the beacon interval allocated for the station, a second beacon frame containing scheduling information of the current beacon interval used for indicating a time period allocated to each group of stations for data transmission within the current beacon interval; when data transmission is required, transmitting, by the station, data within the time period allocated to the group of the station according to indication of the scheduling information. The present invention improves utilization of time periods, saves time resources and enhances transmission efficiency.
