Multi-stream data transmission method, apparatus, and system, and anchor

A multi-stream data transmission apparatus, based on a macro-micro integrated network, wherein the macro-micro integrated network comprises at least one access node, an anchor, and a wireless backhaul device, and data transmission is performed between each access node and the anchor by using a wireless backhaul link established by using a wireless backhaul device, wherein the apparatus is applied to the anchor, and the apparatus comprises:

• a processor;
• and
• a memory coupled to the processor, the memory comprising instructions that, when executed by the processor, cause the processor to:
• obtain resource availability data of all data transmission paths from user equipment (UE) to the anchor, wherein the resource availability data comprises resource data of wireless backhaul links between all access nodes and the anchor;
• determine multiple target data transmission paths according to the resource availability data of all the data transmission paths;
• and
• transmit service data to the UE in a multi-stream manner by using the multiple target data transmission paths, wherein the multiple target data transmission paths comprise a corresponding wireless backhaul link that is established between a target access node and the anchor by using the wireless backhaul device, and the target access node is an access node that is in the at least one access node and that transmits the service data.
