BASE STATION, MOBILE STATION, COMMUNICATION SYSTEM, TRANSMISSION METHOD AND REORDERING METHOD

摘要

FIELD: radio engineering, communication.SUBSTANCE: invention relates to a mobile station and a communication system. The communication system comprises a source base station, a target base station and a mobile station for receiving either a first sequence number or a second sequence number or both from the target base station, wherein the first sequence number is transmitted from the source base station to the target base station, and the second sequence number is added to the packet data convergence layer (PDCP) service data unit (SDU) transmitted from the source base station to the target base station.EFFECT: fast transmission of packets of a mobile station.3 cl, 31 dwg
