Abstract

An embodiment of the invention provides a carrier aggregation method, device and system. The method comprises: a first object determines a non-main carrier cell of CA; the first object is used for controlling a main carrier cell of CA, wherein the main carrier cell is a cell of a first duplex mode, the non-main carrier cell is a cell of a second duplex mode, and the first duplex mode is different to the second duplex mode; the first object interacts a first data with UE, and interacts a second data with UE by a second object; and the second object is used for controlling the non-main carrier cell of CA. The embodiment of the invention provides a solution scheme of carrier CA, and a throughput rate and a frequency spectrum resource use ratio are raised.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a carrier aggregation method, device and system. Background technique [0002] With the rapid development of communication technology, the number of mobile terminal users and the throughput requirements are increasing day by day. However, since the carrier resources of a single cell are limited, when the cell has no free carrier resources to divide, the users in this cell cannot reach the users. Capable of peak throughput. [0003] The 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) introduced Carrier Aggregation (Carrier Aggregation, referred to as CA) technology in the Release 10 phase, by aggregating multiple continuous or non-consecutive carriers into a larger Bandwidth, to meet the requirements of improving the peak throughput of a single user equipment (User Equipment, referred to as UE). The aggregated car...
