Embodiment Construction

[0024] Embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0025] First refer to Figure 1 to Figure 7 , describing the subcarrier configuration method, device and terminal equipment in a multi-carrier communication system according to the first aspect of the present application.

[0026] figure 1 A flow chart of a method for configuring subcarriers in a multi-carrier communication system according to an embodiment of the present application is shown. Such as figure 1 The shown method can be executed by a network-side device in a multi-carrier communication system, so as to configure sub-carriers of a downlink transmission channel.

[0027] Such as figure 1 As shown, first at step 1002, the network side equipment (such as a base station) can obtain the capability information of the terminal device, and then at step 1004, determine the baseband DC carrier position of the terminal device according to the obt...

Abstract

The present application provides a method and a terminal device for reducing interference in a multi-carrier communication system. The method for reducing interference in a multi-carrier communication system according to an embodiment of the present application includes: acquiring network side carrier configuration information; and configuring the baseband DC carrier position of the terminal device to be within the network side downlink transmission bandwidth according to the network side carrier configuration information. corresponding to the carrier position. Through the present application, data reception errors at the baseband DC carrier position of the terminal equipment can be avoided, and the normal operation of the terminal equipment can be ensured.

Description

[0001] The application of the present invention is a divisional application of the invention application with the filing date of September 30, 2010, the application number of 201010298078.8, and the invention title of "Multi-carrier Communication System Subcarrier Allocation Method and Device and Terminal Equipment". technical field [0002] The present application relates to a method and device for configuring subcarriers in a multi-carrier communication system, a method for reducing interference in a multi-carrier communication system, and terminal equipment. Background technique [0003] In the 3GPP multi-carrier communication system, channels on the network side and the terminal device side are both configured as multi-carrier aggregation. Since the terminal equipment does not have IF filtering, there will be strong local oscillator leakage at the position of the baseband DC carrier, which will affect the reception of the subcarrier at this position, which will not only c...
