Abstract

Disclosed is a method for indicating the dual band non-adjacent carrier aggregation capability of a user equipment (UE), comprising: a UE notifying to a network side a combination list of support of non-adjacent carrier aggregation capabilities on respective bands in each band combination supported by the UE, and the maximum number of interval carriers between carriers when the non-adjacent carrier aggregation is supported on respective bands in each band combination; the network side allocating, according to the support of dual band non-adjacent carrier aggregation capability of the UE and the capability of a cell where the UE is located, resources to the UE. Also disclosed is a system for indicating the dual band non-adjacent carrier aggregation capability of a UE. The present invention is capable of explicitly indicating the multi-carrier cases supported by the UE, thereby greatly facilitating carrier configuration on the UE by the network side.

Description

technical field [0001] The present invention relates to a technology for indicating dual-band non-adjacent carrier aggregation capability of user equipment, and in particular to a method and system for indicating dual-band non-adjacent carrier aggregation capability of user equipment. Background technique [0002] In the Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access) network, the Universal Terrestrial Radio Access Network (UTRAN, Universal Terrestrial Radio Access Network) includes a radio network controller (RNC, Radio Network Controller) and a base station (NodeB) Two basic network elements. With the development of WCDMA network, high-speed downlink packet access (HSDPA, High Speed ​​Downlink Packet Access), high-speed uplink packet access (HSUPA, High Speed ​​Uplink Packet Access), dual-cell high-speed downlink packet access (DC -HSDPA, Dual Cell-High speed downlink packet access), dual-band dual-cell high-speed downlink packet acc...
