Embodiment Construction

[0036] figure 1 It is a flowchart of the processing method of the present invention to form the carrier, such as figure 1 shown, including:

[0037] Step 100: Preset a component carrier configuration indicator for processing component carriers.

[0038] In this step, by setting the component carrier configuration indicator, it is determined to add an uplink or downlink component carrier, or to delete an uplink or downlink component carrier, or to add / delete (add and delete) an uplink or The downlink constitutes a carrier. The component carrier configuration indicator includes an operation type indicator field, an operation carrier number indicator field, a component carrier correspondence relationship indicator field, and a signaling allocation indicator field. in,

[0039] The operation type indication field is used to determine the operation type of adding, deleting, and simultaneously adding / deleting uplink or downlink component carriers;

[0040] The operation carrier...

Abstract

The invention discloses a component carrier processing method and a component carrier processing system. The configuration of component carriers is finished by the interaction of a preset component carrier configuration indicator used for processing the component carrier between a base station and a user terminal. By the method provided by the invention, the configuration of the component carriers can be finished by only once signaling interaction between the base station and the user terminal (UT) so as to remarkably shorten the round trip delay of the signaling interaction; and simultaneously, the setting of the component carrier configuration indicator improves the configuration flexibility of the component carriers of the base station, and operations comprising addition, deletion and simultaneous addition / deletion over the component carriers in uplinks and downlinks can be finished by changing different fields of the component carrier configuration indicator so as to improve the height flexibility of the base station.

Description

technical field [0001] The present invention relates to carrier aggregation technology, in particular to a method and system for processing component carriers. Background technique [0002] In the next-generation broadband wireless communication network, in order to improve the throughput of user terminals between cells and the average throughput of user terminals, it is necessary to solve how to support a larger bandwidth under the bandwidth of the current wireless communication system. [0003] At present, in the Long Term Evolution (LTE) of the Third Generation Partnership Project, it has been proposed to use carrier aggregation to effectively support a larger bandwidth in the current wireless communication system to meet the requirements of the new generation wireless communication system. The requirements for indicators such as throughput and peak rate in the standard. Carrier aggregation is a key technology for supporting larger bandwidth in future wireless communicat...
