Abstract

The invention provides a method, in a first base station, of supporting dual connectivity in a carrier aggregation based communication system, wherein the first base station at least serves one or more secondary cells, and each secondary cell has an activated state and a de-activated state, the method comprising: sending a request message to other base stations, when the first base station will change a state of a secondary cell allocated to a user equipment by the first base station, the request message at least including ID of the user equipment; receiving a response message from the other stations, the response message at least including the ID of the user equipment, an index of a secondary cell allocated to the user equipment by the other base station, and a state of a secondary cell corresponding to the index; and generating and sending a MAC layer control signaling to the user equipment based on the response message, wherein the MAC layer control signaling indicating states of all secondary cells allocated to the user equipment.
