Method and device for distributing constituting carrier waves in carrier aggregation

Abstract

The present invention discloses a method and an apparatus for allocating component carriers in carrier aggregation. The said method includes that: a base station collects component carrier usage quality information of a user equipment; the base station configures component carriers for the user equipment according to the collected component carrier usage quality information of the user equipment. The said apparatus includes a collector and a configurator set in the base station. The said collector is used to collect component carrier usage quality information of the user equipment. The said configurator is used to allocate component carriers for the user equipment according to the component carrier usage quality information of the user equipment collected by the collector. By applying the said method and apparatus, the validity of a user using component carriers can be guaranteed.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and device for allocating 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] The LTE-A system (Long Term Evolution-Advanced, Advanced Long Term Evolution) is a next-generation evolution system of the LTE (Long Term Evolution, Long Term Evolution) system of 3GPP (Third Generation Partnership), which proposes a carrier aggregation technology for User equipment (User Equipment, referred to as UE) provides greater bandwidth and increases the peak rate of the UE, so as to meet the re...

Problems solved by technology

[0004] Although carrier aggregation has the advantage of providing greater bandwidth, however, inappropriate carrier aggregation will affect the effectiveness of carrier aggregation technology applications

For example, inter-cell interference has a huge impact on the throughput and average throughput of the user equipment. If the carrier of the user equipment includes a carrier that suffers from severe inter-cell interference, even if a larger bandwidth is obtained through carrier aggregation, it will still be due to The aggregated carriers contain interfered carriers, which seriously degrades the throughput and rate performance of the user equipment, offsetting the benefits of carrier aggregation
