Problems solved by technology

However, if the RF hardware design of the terminal is changed, it will bring about a certain cost increase
Another solution is the time-division multiplexing mode (time-division multiplexing, TDM), that is, when the terminal transmits the entire low-frequency uplink, the downlink data is not scheduled during the entire high-frequency downlink, but this solution will cause the terminal to schedule uplink and downlink The opportunity is directly halved, so that the downlink and uplink rates of the terminal and the system as a whole are severely reduced

Embodiment Construction

[0017] A method, device and system for reducing harmonic interference provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0018] The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations.

[0019] The terms "first" and "second" in the specification and drawings of the present application are used to distinguish different objects, or to distinguish different processes for the same object, rather than to describe a specific sequence of objects.

[0020] In addition, the terms "including" and "having" mentioned in the description of the present application and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or...

Abstract

The invention provides a method and device for reducing harmonic interference, relates to the field of communication, and can improve the spectrum utilization rate of a system. The method is applied to a scheduler, the scheduler receives and transmits data in a first frequency range and a second frequency range, the first frequency range is higher than the second frequency range, and the method comprises the following steps: determining whether a frequency signal in the second frequency range generates harmonic interference with a frequency signal in the first frequency range; the harmonic interference specifically comprises N-order harmonic interference, wherein N is a natural number greater than or equal to 2; if yes, determining a target frequency range according to the second frequencyrange; and transmitting and receiving data in other frequency ranges except the target frequency range in the first frequency range.

Description

technical field [0001] The present application relates to the communication field, in particular to a method and device for reducing harmonic interference. Background technique [0002] Dual connectivity is an important solution for the fifth generation (5th generation, 5G) mobile communication network, including long term evolution-new radio (LTE-NR) dual connectivity and new radio-new radio-new radio, NR-NR) dual connectivity. LTE-NR dual connectivity can use LTE as the coverage layer and NR as the capacity layer. Terminals working in dual connectivity mode can experience the performance gains brought by both LTE and NR systems. [0003] However, when the terminal transmits data on a low-frequency band (LTE) and receives data on another high-frequency band (NR) at the same time, and the two frequency bands meet certain rules, the multiplied signal of the terminal's low-frequency transmission signal will fall in the In the high-frequency receiving frequency band, local in...
