Abstract

An embodiment of the invention provides a method for achieving carrier aggregation, a base station and user equipment. The method includes that a main base station determines to add a cell to the UE; and the main base station sends a first message to the UE, wherein the first message is used for indicating the UE to add the cell and contains configuration information of the cell and an identification or index of the base station where the cell is located, and the base station where the cell is located is an auxiliary base station. According to the method, the base station and the UE, the cell of another base station can be added for the UE under the control of the main base station of the UE to achieve carrier aggregation between base stations, and therefore the user throughout of the UE is further improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and more specifically, relate to a method for implementing carrier aggregation, a base station, and user equipment. Background technique [0002] With the development of the mobile communication system, the quality of service that the system can provide is getting higher and higher. In order to maintain the long-term competitive advantage of 3GPP, the standard formulation work of LTE-A (LTE-Advanced, subsequent evolution of LTE) is in progress. In order to improve the spectral efficiency of the system and the throughput of a user equipment (User Equipment, UE), carrier aggregation (CA, Carrier Aggregation) is introduced into LTE-A. Carrier aggregation means that a UE can simultaneously use multiple component carriers (CC, Component Carrier) for uplink and downlink communication, thereby supporting high-speed data transmission. [0003] The Release-10 version of 3G...
