A wireless network scheduling method, comprising: determining, by a second access device, a serving cell subset to which a terminal belongs, wherein the terminal is a destination terminal to which the second access device sends downlink data, the serving cell subset is a set of serving cells that can be accessed by the terminal, and each serving cell is corresponding to a first access device; 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, wherein the downlink scheduling information is used to instruct the first access device to send the downlink data to the terminal; wherein after the sending downlink data and downlink scheduling information, the method further comprises: receiving, by the second access device, first feedback information sent by the first access device corresponding to the serving cell in the serving cell subset; and determining, according to the first feedback information, whether the terminal successfully or unsuccessfully receives the downlink data; and wherein the determining, according to the first feedback information, whether the terminal successfully or unsuccessfully receives the downlink data is characterised by: if the received first feedback information indicates that first access devices of a specified quantity or a specified proportion successfully receive the downlink data, determining that the terminal successfully receives the downlink data; or if the first feedback information indicates that a quantity or a proportion of first access devices that successfully receive the downlink data is less than a specified quantity or a specified proportion, confirming that the terminal unsuccessfully receives the downlink data. determining, by a second access device, a serving cell subset to which a terminal belongs, wherein the terminal is a destination terminal to which the second access device sends downlink data, the serving cell subset is a set of serving cells that can be accessed by the terminal, and each serving cell is corresponding to a first access device; 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, wherein the downlink scheduling information is used to instruct the first access device to send the downlink data to the terminal; wherein after the sending downlink data and downlink scheduling information, the method further comprises: receiving, by the second access device, first feedback information sent by the first access device corresponding to the serving cell in the serving cell subset; and determining, according to the first feedback information, whether the terminal successfully or unsuccessfully receives the downlink data; and wherein the determining, according to the first feedback information, whether the terminal successfully or unsuccessfully receives the downlink data is characterised by: if the received first feedback information indicates that first access devices of a specified quantity or a specified proportion successfully receive the downlink data, determining that the terminal successfully receives the downlink data; or if the first feedback information indicates that a quantity or a proportion of first access devices that successfully receive the downlink data is less than a specified quantity or a specified proportion, confirming that the terminal unsuccessfully receives the downlink data. receiving, by the second access device, first feedback information sent by the first access device corresponding to the serving cell in the serving cell subset; and determining, according to the first feedback information, whether the terminal successfully or unsuccessfully receives the downlink data; and wherein the determining, according to the first feedback information, whether the terminal successfully or unsuccessfully receives the downlink data is characterised by: if the received first feedback information indicates that first access devices of a specified quantity or a specified proportion successfully receive the downlink data, determining that the terminal successfully receives the downlink data; or if the first feedback information indicates that a quantity or a proportion of first access devices that successfully receive the downlink data is less than a specified quantity or a specified proportion, confirming that the terminal unsuccessfully receives the downlink data.
