Method and device for distributing constituting carrier waves in carrier aggregation

Abstract

The invention discloses a method and a device for distributing constituting carrier waves in carrier aggregation. The method comprises the following steps that: a base station acquires use quality information of the constituting carrier waves of user equipment; and the base station allocates the constituting carrier waves to the user equipment according to the acquired use quality information of the constituting carrier waves of the user equipment. The device comprises an acquisition device and an allocator, wherein the acquisition device and the allocator are arranged on the base station; the acquisition device is used for acquiring the use quality information of the constituting carrier waves of the user equipment; and the allocator is used for allocating the constituting carrier waves to the user equipment according to the acquired use quality information of the constituting carrier waves of the user equipment. Due to the adoption of the method and the device, the effectiveness of the utilization of the constituting carrier waves by a user can be ensured.

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
