Coordinated Multi-Point (CoMP) transmission/reception technology has been the focus of much attention recently and has becom a key research interest in 3GPP LTE-Advanced due to its ability to improve both cell-edge and average system performance.However,CoMP technology requires brand-new handover mechanism,or else its real performance will be limited.This paper proposes a novel handover mechanism supporting CoMP based on the handover scenario in CoMP communication system architecture,including information sharing and signaling transmission procedure of CoMP cooperating sets handover and CoMP transmission points selection/update.The proposed scheme could not only support CoMP well,but also reduce the overhead of information exchange and signaling transmission.
