    Abstract: The present invention relates to the field of communications technologies, and in particular, to a data scheduling method and apparatus, so as to resolve a problem that performing data scheduling on a data node by different evolved NodeBs participating in CA may cause a case in which a range supported by a processing capability of the data node is exceeded, or may cause a case in which the data node cannot fully leverage a processing capability of the data node. The method includes: sending, by the data node, scheduling limitation indication information to a first communications node; receiving, by the data node, data scheduling information that is sent by the first communications node to the data node; and sending, by the data node, uplink data to the first communications node, or receiving, by the data node, downlink data sent by the first communications node according to the data scheduling information.
