[0025] Functional Overview

[0026] Considering the problem that the throughput and rate performance of the user terminal of the aggregated carrier is severely degraded due to the lack of consideration of inter-cell interference in carrier aggregation, an embodiment of the present invention provides a carrier selection scheme, and the carrier aggregation involved in this scheme is the future The key technology supporting larger bandwidth in the wireless communication system is to determine the bandwidth capability of the user terminal (UT) in the wireless communication network through the base station (Base Station, BS for short), and the base station groups different bandwidth capabilities and performs Carrier pre-aggregation forms a new set of basic carriers that have greater bandwidth capabilities and are backward compatible with the bandwidth capabilities of some UTs in the existing wireless communication network system. In order to make the use of the pre-aggregated new b...

Abstract

The invention discloses carrier selection method and device. The method comprises the steps of: determining carrier aggregation information by a base station, wherein, the carrier aggregation information comprises the size of a carrier which can participate in a carrier pre-aggregation, the bandwidth capacity of a user terminal and the new set number of the carrier pre-aggregation; selecting carrier members from the new set number of the carrier pre- aggregation to form a carrier set so as to complete the pre- aggregation by the base station according to cell interference condition and a determined size; and selecting the carriers from the carrier set participating in the pre- aggregation according to the bandwidth capacity of the user terminal and the determined size to complete the aggregation. The invention ensures the communication quality in wireless communication networks.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a carrier selection method and device. Background technique [0002] At present, 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 has become a key to improving the throughput of user terminals between cells and the average throughput of user terminals factors and face serious challenges. [0003] In the Long Term Evolution (LTE for short) of the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP for short), it is proposed to use carrier aggregation to effectively support more Large bandwidth to meet the requirements of the new generation of wireless standards for throughput, peak rate and other indicators. Carrier aggregation is a key technology for supporting larger bandwidth in future wireless comm...
