Abstract: Embodiments of the present invention disclose a data transmission method and apparatus. The data transmission method includes: performing, by a Packet Data Convergence Protocol PDCP entity, lossless transmission on PDCP protocol data units PDUs or PDCP service data units SDUs, where each of the PDCP PDUs or the SDUs is associated with one serial number. In this embodiment, during lossless transmission, no data packet is lost, thereby ensuring communication quality in an inter-station carrier aggregation scenario and achieving an optimization objective.

Abstract: In a cell handover method and system, after receiving a pre-handover instruction sent by a first eNB, a random access preamble is sent by the UE, and a radio bearer corresponding to a second eNB is established by the UE, according to configuration information in the pre-handover instruction. The UE receives a timing advance that is usable by the UE in performing uplink synchronization with the second eNB and an uplink indication message that indicates an uplink resource that is usable by the UE in communications with the second eNB.
