摘要： A duplication transmission method and device, used for solving the problem in existing technology of a scheme for implementing packet data convergence protocol (PDCP) duplication having yet to be implemented in a central unit/distribute unit (CU/DU) separation scenario. According to the embodiments of the present invention, after determining the need for PDCP duplication transmission on a radio bearer, a CU sends a PDCP data packet transmitted on the radio bearer to a DU and instructs the DU to carry out the PDCP duplication transmission; and the DU sends the PDCP data packet to multiple radio link control (RLC) entities corresponding to the radio bearer so as to carry out the PDCP duplication transmission. Since the CU may instruct the DU to perform the PDCP duplication transmission, the PDCP data packet is subject to duplication transmission in the CU/DU separation scenario, thereby further improving the system performance.

摘要： The embodiments of this application relate to the field of wireless communications. Disclosed are an auxiliary information reporting and information sending method and device, so that a target base station can acquire the latest auxiliary information of a user equipment (UE) and then can provide the most reasonable configuration for the UE. In this application, the UE reports the auxiliary information to a source base station, and determines whether it is required to re-report the auxiliary information in a target cell; if determining that it is required to re-report the auxiliary information in the target cell, the user equipment reports the auxiliary information to the target base station after being switched to the target cell. It can be seen that, in this solution, the target base station can acquire the latest auxiliary information of the UE, so as to provide the most reasonable configuration for the UE.
