Low-complexity multi-base-station mimo method and apparatus for up-link

A low-complexity, multi-base-station MIMO method for use in a communication network includes: determining the cluster of the user equipment, said cluster includes performing MIMO base-station convergence for the user equipment; processing procedure for checking user equipment signal and cancelling the greatest interference between users; and the service base-station in the user cluster performs combination of interference-cancelled user signals coming from every base-station.
