Embodiment Construction

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0033] The terms "first", "second", "third" and "fourth" in the specification and claims of the present invention are used to distinguish different objects, rather than to describe a specific order of objects. For example, the first frequency band, the second frequency band, the third frequency band, and the fourth frequency band are used to distinguish different frequency bands, not to describe a specific order of the frequency bands.

Abstract

The embodiment of the invention discloses a method and a device for reducing interference, which relate to the technical field of communication, and are used for solving the problem that the receptionsensitivity of a terminal may be lowered due to harmonic interference when a LTE network and a 5G network form a double connection. The methods include: when the bandwidth of the target frequency band is larger than a preset threshold value, sending a first request message to the first network device, the first request message is used for requesting the first network device to transmit data in atarget frequency band, the target frequency band is a frequency band in the first frequency band other than the first overlapping frequency band, the first overlapping frequency band is a portion where the first frequency band and the second frequency band overlap, the first frequency band is a frequency band corresponding to the first resource allocated by the first network device to the terminalin the first network, and the second frequency band is a frequency band corresponding to the second resource allocated by the second network device to the terminal in the second network. The terminalreceives a response message sent by the first network device, and the response message is used for confirming that the first network device transmits data in a target frequency band.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method and device for reducing interference. Background technique [0002] At present, with the development of the fifth-generation mobile communication (5G) network, under the non-standalone network (Non-StandAlone, referred to as NSA) framework, a dual connection mechanism between the LTE network and the 5G network is proposed, that is, the terminal is required to support dual The connection technology uses dual radios to simultaneously connect the LTE network and the 5G network, and uses dual links of the LTE link and the 5G link for data transmission. [0003] However, when the 5G network and the LTE network form a dual connection, due to factors such as the nonlinearity of the radio frequency device, the terminal may have self-interference problems, that is, the uplink may cause harmonic interference to the downlink reception, resulting ...
