A resource division method, comprising at least one terminal device, at least one first node, and at least one second node, wherein both the first node and the second node have a scheduling function, and the method comprises: dividing, by the second node, a radio resource of the first node into a first resource and a second resource; wherein the first resource is scheduled by the first node, wherein the scheduling is distributed scheduling, and wherein the second resource is scheduled by the second node, wherein the scheduling is centralized scheduling; and if determining that the terminal device is scheduled by the second node, sending, by the second node, a data packet that has been processed by using the scheduling function of the second node and third resource indication information to the first node, wherein a third resource indicated by the third resource indication information is a part of or all of the second resource, and the third resource indication information is used for instructing the first node to send, after processing the data packet that has been processed by using the scheduling function of the second node, the data packet that has been processed by the first node to the terminal device by using the third resource; or if the terminal device is scheduled by the first node, sending, by the second node, a data packet that has not been processed by using the scheduling function of the second node to the first node, wherein after processing the data packet that has not been processed by using the scheduling function of the second node, the first node sends the data packet that has been processed by the first node to the terminal device by using a fourth resource, and the fourth resource is a part of or all of the first resource; wherein in centralized scheduling a node receives data from a SGW and processes the data by PDCP, RLC, MAC and PHY layers before transmission, and wherein in distributed scheduling, data that has not been processed by PDCP, RLC, MAC and PHY layers is transmitted between the SGW and a node; wherein the method further comprises: when basic information of the terminal device changes or network information of the second node or the first node changes, negotiating, by the second node with the first node, to divide the radio resource of the first node. dividing, by the second node, a radio resource of the first node into a first resource and a second resource; wherein the first resource is scheduled by the first node, wherein the scheduling is distributed scheduling, and wherein the second resource is scheduled by the second node, wherein the scheduling is centralized scheduling; and if determining that the terminal device is scheduled by the second node, sending, by the second node, a data packet that has been processed by using the scheduling function of the second node and third resource indication information to the first node, wherein a third resource indicated by the third resource indication information is a part of or all of the second resource, and the third resource indication information is used for instructing the first node to send, after processing the data packet that has been processed by using the scheduling function of the second node, the data packet that has been processed by the first node to the terminal device by using the third resource; or if the terminal device is scheduled by the first node, sending, by the second node, a data packet that has not been processed by using the scheduling function of the second node to the first node, wherein after processing the data packet that has not been processed by using the scheduling function of the second node, the first node sends the data packet that has been processed by the first node to the terminal device by using a fourth resource, and the fourth resource is a part of or all of the first resource; wherein in centralized scheduling a node receives data from a SGW and processes the data by PDCP, RLC, MAC and PHY layers before transmission, and wherein in distributed scheduling, data that has not been processed by PDCP, RLC, MAC and PHY layers is transmitted between the SGW and a node; wherein the method further comprises: when basic information of the terminal device changes or network information of the second node or the first node changes, negotiating, by the second node with the first node, to divide the radio resource of the first node.
