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.
