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

Abstract

The present application provides a method and device for reducing harmonic interference, which relate to the communication field and can improve the frequency spectrum utilization rate of the system. The method is applied to a scheduler, and the scheduler transmits and receives data on a first frequency range and a second frequency range, the first frequency range is higher than the second frequency range, and the method includes: determining whether a frequency signal in the second frequency range is consistent with the first frequency range Harmonic interference occurs to a frequency signal in a frequency range; the harmonic interference specifically includes: N-order harmonic interference, where N is a natural number greater than or equal to 2; if so, determine the target frequency range according to the second frequency range; and in the first Send and receive data on frequency ranges other than the target frequency range in the frequency range.

Description

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