A wireless network scheduling method, an access device, and a wireless network are provided. Implementation of the method includes: determining, by a second access device, a serving cell subset to which a terminal belongs; and sending, by the second access device, downlink data and downlink scheduling information to the first access device corresponding to the serving cell in the serving cell subset, where the downlink scheduling information is used to instruct the first access device to send the downlink data to the terminal.
