CARRIER AGGREGATION METHOD AND DEVICE IN LTE-A SYSTEM

摘要

A method and apparatus for achieving carrier aggregation in a Long Term Evolution Advanced (LTE-A) system are disclosed. The method includes: after a User Equipment (UE) with carrier aggregation capability initially accesses a primary cell, a network side constructing a secondary cell candidate cell list for the UE and selecting a secondary cell for the UE from the secondary cell candidate cell list; the network side deciding to perform the following operations on the current secondary cells of the UE according to quality of service of the secondary cell: deleting a corresponding secondary cell from the current secondary cells of the UE; or adding a corresponding secondary cell into the current secondary cells of the UE. With the above solution, carrier aggregation can be reasonably selected and used in the LTE-A system, the system can obtain a larger bandwidth, and the throughput of the system is improved significantly.
