Abstract:
Embodiments of the present invention disclose a method for coordinated multi-cell transmission, a central controller and a User Equipment (UE). In one embodiment, the method includes: determining, by a central controller, at least one candidate cooperating set in a super-cell, wherein each cell in the super-cell belongs to at least one candidate cooperating set, and broadcasting information of the at least one candidate cooperating set determined to all UEs in the super-cell; selecting, by each UE, a candidate cooperating set from the at least one candidate cooperating set as a cooperating set of the UE, and feeding back information of the cooperating set selected to the central controller; and determining, by the central controller, all cooperating sets in the super-cell and UEs participating in cooperation in each cooperating set according to the information of the selected cooperating set fed back by each UE.
