<p>The present invention provides an uplink progressive multi-point coordinated MIMO processing scheme. A coordinated processing management equipment determines whether it is necessary to send ACK or NACK message to neighboring base stations in the same CoMP cluster; when it is necessary to send ACK message to the neighboring base stations, the ACK message is sent to all the neighboring base stations in the cluster which have not participated in joint to inform each neighboring base stations that it is not necessary to send user data to the coordinated processing management equipment; when it is necessary to send NACK message to the neighboring base stations, the NACK message is sent to at least one neighboring base station in the cluster which has not participated in joint to inform the at least one base stations to send user data to the coordinated processing management equipment; according to the user data obtained by the base station and the user data from the at least one neighboring base stations, the coordinated processing management equipment performs joint detection and combination. Through the application of solution of the invention, the backhaul cost has been saved and the complexity of the |system realization is reduced.</p> |
