Abstract

A method and apparatus for multi-cell cooperative transmission are provided, for increasing the capacity of an MS at a cell edge through cooperation among a plurality of adjacent cells or BSs each having a plurality of antennas. The present invention improves Coordinated Multi Point (CoMP) performance due to simple CoMP implementation and reduced backhaul overhead and delay, and enables simple implementation of a CoMP resource allocation process and reduces handover overhead by eliminating handover between CoMP processing units.
