Constituted carrier control method in carrier aggregation

Abstract

The invention discloses a constituted carrier control method in carrier aggregation, comprising the following steps: determining candidate anchor carriers and non-anchor carriers by a base station, and classifying the constituted carriers; dividing all the candidate constituted carriers into two groups, namely an independent use type and a carrier group use type; when the carrier group use type is not supported in the constituted carrier selection, utilizing an indication field as a field to indicate the use method of carriers in the independent use type by constituted carriers; and when the carrier group use type is supported in the carrier constitution selection, dividing an indication field into a subfield of the independent use type and a subfield of a carrier group use type, utilizing the subfield of the independent use type and the subfield of a carrier group use type to respectively indicate the use methods of carriers in the two types. By the technical scheme in the invention, the carrier group is adopted to further reduce the number of the carrier combinations required to be indicated, and the base station uniformly dispatch the carrier group as a whole, thus reducing the dispatching complexity.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method for controlling component carriers in carrier aggregation. Background technique [0002] In the next-generation broadband wireless communication network, how to support a larger bandwidth in the wireless communication network under the bandwidth of the current wireless communication system becomes a key factor in improving the throughput of user terminals between cells and the average throughput of user terminals. Facing severe challenges. [0003] At present, in the Long Term Evolution (LTE) of the Third Generation Partnership Project, it is proposed to use carrier aggregation to effectively support a larger bandwidth in the current wireless communication system, so as to meet the new generation of wireless standards. The requirements for indicators such as throughput and peak rate. Carrier aggregation is a key technology for supporting larger bandwid...

Problems solved by technology

However, the current carrier aggregation discussed in LTE-Advanced does not take into account the impact of inter-cell interference that plays an important role in the throughput of user terminals between cells and the average throughput of user terminals. If the aggregated carrier part suffers from severe inter-cell interference, then , even if a larger bandwidth is obtained, the throughput and rate performance of the user terminal using this part of the aggregated carrier will be severely degraded due to severe inter-cell interference, thereby offsetting the benefits of carrier aggregation
