Embodiment Construction

[0026] Functional Overview

[0027] Considering that the impact of inter-cell interference in carrier aggregation on UT throughput and average throughput is not considered in the related art, resulting in the degradation of UT throughput and rate performance, the embodiment of the present invention provides a carrier aggregation implementation solution, Carrier aggregation based on resource reservation is used to reserve important control channels carried in carrier aggregation and carrier parts that play an important role in important physical processes such as random access, which can reduce inter-cell interference. Next, expand the number of carriers used by the UT to meet the various needs of the new wireless communication network and ensure the communication quality in the wireless communication network.

[0028] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each oth...

Abstract

The invention discloses a method and a base station (BS) for realizing carrier aggregation. The method comprises the following steps that: the base station (BS) determines reservation information, wherein the reservation information comprises a reserved resource for carrier aggregation and an ability of UT; the base station (BS) selects a first carrier resource from the reserved resource according to the ability of the UT, and selects a second carrier resource for carrying the data of the UT from the resources except the reserved resource; and the base station (BS) aggregates the first carrier resource and the second carrier resource. The method and the base station (BS) for realizing carrier aggregation can expand the number of the carrier used by the UT on the premise of reducing the inter-cell interference so as to meet various requirements of a new wireless communication network and ensure the communication quality in the wireless communication network.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method for implementing carrier aggregation and a base station. 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 problem of improving the throughput of user terminals (UT) between cells and the average UT throughput. A key factor in throughput. [0003] At present, in the Long Term Evolution (LTE) system 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 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 to sup...
