Precoder weights employed at a base station which coordinates with other base stations to form a super-cell are determined by: (a) determining an initial downlink precoding matrix at the base station for a mobile station serviced by the base station in the super-cell; (b) revising a downlink receiver matrix associated with the mobile station based on the initial downlink precoding matrix; (c) transforming the downlink receiver matrix to an uplink precoder matrix associated with the mobile station; (d) revising an uplink receiver matrix associated with each base station in uplink communication with the mobile station based on the uplink precoder matrix associated with the mobile station; and (e) revising the initial downlink precoding matrix by transforming the uplink receiver matrix to a revised downlink precoding matrix. Steps (b), (c), (d) and (e) are repeated for a particular number of iterations to determine a final downlink precoding matrix for the mobile station. |
