Abstract
A communication system is disclosed in which coordinated multi-point transmissions for a mobile device are carried out in two stages. In the first stage, a central controller obtains Channel State Information (CSI) reports from multiple transmission points, based on which the controller estimates respective data rates for transmissions between each transmission point and the mobile device. The controller determines an active set of transmission points to be associated with the mobile device, and informs the transmission points about the association made. In the second stage, the transmission points included in the active set carry out scheduling for the mobile device independently from each other until the controller updates the active set of transmission points.
