3. For use in a wireless communications network, a subscriber station capable comprising:
-
a receiver configured to receive a first indication of an active set of cells from an anchor cell; and a transmitter configured to transmit information related to the active set of cells to the anchor cell, wherein the receiver is further configured to receive a second indication of a subset of the active set from the anchor cell through the physical downlink control channel (PDCCH), the subset of the active cells being determined by the anchor cell, and wherein the transmitter is further configured to transmit information channel related information for the subset of the active cells to the anchor cell. - View Dependent Claims (4, 5, 6, 7, 8)

18. A method of operating a network, the method comprising:
-
selecting, by an anchor cell, a subset of cells from an active set of cells; transmitting, by the anchor cell, an indication of the subset of cells to a subscriber station; transmitting, by the subscriber station, channel-related information for the subset of cells to the anchor cell; selecting, by the anchor cell, one or more cells from the subset of cells to participate in a coordinated multipoint (CoMP) joint transmission based at least partly upon the channel-related information; communicating, by the anchor cell, the cell_ID of the anchor cell to the one or more cells that have been selected to participate in the CoMP joint transmission; and determining, by each of the one or more selected cells, a cell-specific frequency shift based on the anchor cell cell_ID for one or more dedicated antenna ports. - View Dependent Claims (19, 20, 21, 22, 23)
