Abstract: A joint data transmission method and a device are disclosed. Distributed transmit units are divided into subclusters, target user equipment is selected from each subcluster, and further, grouping is performed on a user equipment basis to reduce a quantity of dimensions, so that a joint transmission parameter is determined, and joint data transmission is performed. This way, interference between subclusters can be avoided and complexity is reduced, thereby improving system performance.

Abstract: Embodiments of the present application provide a load balancing method and a network control node. An entity in which a serving cell is located selects a scheduling cell for an edge UE, and instructs the scheduling cell to allocate a data channel for the edge UE, and a control channel is retained in the serving cell and is not handed over. In this way, in a case of being transparent to the UE, an objective of load balancing is achieved by automatic fast coordinating and scheduling without handover. It can be seen that, in the foregoing load balancing manner, a data channel is used as transferring granularity, and a handover time delay does not need to be introduced, thereby implementing a function of fast balancing instantaneous load, and improving load balancing efficiency.
