摘要： A method for forwarding data during cell handover includes: forwarding, by a source base station, user plane data of Packet Data Convergence Protocol, PDCP, data units that have not been transmitted to a User Equipment, UE, to a target base station in a PDCP layer during cell handover. In addition, embodiments of the present invention further provide a system and devices for forwarding data during cell handover. In the method, a system and base stations are provided by the present invention, the data that have not been transmitted are forwarded in a layered manner respectively in at least one of the PDCP layer and RLC layer. Therefore, data transmission during cell handover is implemented and data loss due to the handover is avoided.

摘要： A method, an eNodeB, and a system for timing adjustment to a component carrier are provided. The method includes the following steps: receiving an instruction signaling, in which the instruction signaling is used for instructing a downlink component carrier used as a timing reference for an uplink component carrier; and adjusting the uplink component carrier by using the downlink component carrier as timing reference time. Through the embodiments of the present disclosure, the downlink component carrier used as the timing adjustment reference for the uplink component carrier is specified in the sent instruction signaling. The timing reference time used by the terminal during the TA adjustment of the uplink component carrier may be clarified and the TA adjustment of the uplink component carrier may be accurately confirmed.
