Abstract

The invention discloses a method and device for dynamic management of secondary cells in carrier aggregation. A primary cell is configured for user equipment (UE) by an evolved Node B (eNB). The method comprises the following steps of: firstly selecting secondary cells, wherein the secondary cells are supported by the UE, have the coverage area the same as that of the primary cell, and comprise different-frequency neighbor cells which are located in the coverage area of the primary cell and configured for the UE; and selecting the secondary cells for the UE from the rest different-frequency neighbor cells of the primary cell when the number of the secondary cells for the UE can not meet the bandwidth needs of the carrier aggregation. The device comprises a secondary cell selection module and a secondary cell additional selection module. The method and the device have the advantages that the problem of secondary cell management in the carrier aggregation is solved, and the dynamic management of the secondary cells is realized by flexibly using the existing neighbor cell configuration technology and measurement technology, so that a key technical support for the realization of a carrier aggregation function is provided.

Description

technical field

[0001] The present invention relates to the technical field of LTE (Long Term Evolution, long-term evolution) system, and in particular to a method and device for dynamically managing a secondary cell in carrier aggregation. Background technique

[0002] In order to meet the peak rate requirements, the LTE-A (Long Term Evolution-Advanced) system currently supports a maximum bandwidth of 100MHz. However, it is difficult to find such a large bandwidth in the existing available spectrum resources, and large bandwidth is critical for the hardware design of base stations and terminals. bring great difficulty. In addition, for spectrum resources scattered in multiple frequency bands, a technology is urgently needed to make full use of them. Based on the above considerations, the LTE-A system introduces the key technology of CA (Carrier Aggregation, carrier aggregation).

[0003] Carrier aggregation is a function introduced by 3GPP R10 (3rd Generation Partnership ...
