HANDOVER METHOD, WIRELESS BASE STATION, AND MOBILE STATION

摘要

This invention implements "RRC diversity" in a handover procedure between cells under different radio base stations (eNB), while considering conditions in a MAC layer. A handover method of the invention includes: a step A of notifying, by a radio base station (eNB #1), a radio base station (eNB #10) of a HARQ process; a step B of transmitting, by the radio base station (eNB #1), "HO command" to a mobile station (UE) by using a HARQ process different from the HARQ process notified to the radio base station (eNB #10) ; and a step C of transmitting, by the radio base station (eNB #10), "HO command" to the mobile station (UE) by using the HARQ process notified by the radio base station (eNB #1).
