METHOD FOR COORDINATED MULTI-CELL TRANSMISSION, CENTRAL CONTROLLER AND USER EQUIPMENT
First Claim
1. A method for coordinated multi-cell transmission, comprising:
- 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 User Equipments (UEs) in the super-cell;
selecting, by each of the UEs, 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 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 cooperating set fed back by each of the UEs.

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.
