Problems solved by technology

The industry has proposed a carrier aggregation method in which TDD terminals aggregate TDD carriers and FDD terminals aggregate FDD carriers, but the specific implementation scheme has not yet been determined.
And different modes of carrier aggregation cannot be realized, that is, TDD terminals cannot aggregate FDD carriers, and FDD terminals cannot aggregate TDD carriers

Abstract

The invention discloses a carrier aggregation realizing method, which comprises that: a connected mobile terminal receives carrier aggregation control information sent by a base station, wherein the carrier aggregation control information contains carrier identifiers of target carriers of downlink operation carrier aggregation and wireless resource allocation information of the target carriers; and the mobile terminal determines the target carriers according to the carrier identifiers and the wireless resource allocation information, monitors the downlink control channels of the target carriers, resolves the downlink control information of cell-radio network temporary identifier (C-RNTI) of the mobile terminal and acquires downlink data that the base station sends to the mobile terminal from a downlink shared channel. The invention also discloses a corresponding base station, a mobile terminal and a carrier aggregation realizing system formed thereby. The method, the device and the system enable both TDD terminals and FDD terminals to aggregate TDD carriers and FDD carriers.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method for implementing carrier aggregation, a corresponding base station and a mobile terminal, and a system for implementing carrier aggregation. Background technique [0002] The subsequent enhanced version of 3GPP Long Term Evolution (LTE) is called LTE-Advanced (LTE-A for short), which introduces many new technologies, and carrier aggregation (carrier aggregation) technology is the key to supporting higher bandwidth transmission Technology is also brought into it. The basic principle of carrier aggregation is to meet higher bandwidth requirements by aggregating two or more basic carriers together. After the carrier aggregation technology is introduced, the number of working carriers in a cell changes from one to multiple, forming a multi-carrier communication scenario. In the RAN1#57bis meeting of 3GPP, these carriers are divided into three categories, namel...
