Abstract

Provided are a data transmission method, user equipment and a base station. The data transmission method can comprises: UE receives auxiliary configuration information sent from PeNB and the auxiliary configuration information comprises information of a second DRB allocated by SeNB for the UE in SCell; the SeNB manages the SCell, and the SCell is a auxiliary zone of the UE; the UE binds a first EPS-Bearer and the second DRB, and before the first EPS-Bearer and the second DRB are bound, the first EPS-Bearer and a first DRB are bound, the first DRB carries out wireless bearing of data allocated by PeNB for the UE in PCell, the PeNB manages the PCell, the PCell is a main zone of the UE; the UE uses the second DRB bound with the first EPS-Bearer to transmit data flow.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a data transmission method, user equipment, and a base station. Background technique [0002] Carrier Aggregation (CA) technology means that user equipment (User Equipment, UE) transmits and receives data from different cells (Cells) at the same time. Inter-site CA (Inter-eNB CA) refers to two Cells used for CA. belong to different evolved base stations (evolved NodeB, eNB). Different-site CA technology can bring higher throughput rate to users, improve user experience, and also improve network resource utilization. Based on the above advantages, the off-site CA technology has become a hot spot in current research. [0003] For the different-site CA technology, traffic distribution is usually performed at the Internet Protocol (IP) layer, and there are complete L1 and L2 protocol stacks in the primary base station (Primary eNB, PeNB) and secondary base s...
