Abstract

The invention provides a method and device for configuring subcarriers in a multi-carrier communication system, a method for reducing interference in the multi-carrier communication system and terminal equipment. The method for configuring subcarriers in the multi-carrier communication system comprises the following steps: obtaining the capability information of the terminal equipment; determining the base band direct current carrier position of the terminal equipment according to the capability information; determining the direct current corresponding position corresponding to the base band direct current carrier position in the network side downlink transmission bandwidth; and configuring the subcarriers in the direct current corresponding position in the network side downlink transmission bandwidth as void subcarriers or useless subcarriers. By adopting the methods, the device and the terminal equipment, data reception error in the base band direct current carrier position of the terminal equipment can be avoided, thus ensuring normal operation of the terminal equipment.

Description

technical field [0001] 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 [0002] 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 cause the wrong reception of the subcarrier, but also cause the related resource block Receive error, affect the normal work of the terminal. [0003] For the current LTE multi-carrier communication system or carrier aggregation system, the center position of each carrier of the downlink transmission bandwidth on the n...
