Method and device for reducing harmonic interference

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 resource scheduling system. The resource scheduling system comprises a first scheduler and a second scheduler, the first scheduler receives and transmits data in a first frequency range; the second scheduler receives and transmits data in a second frequency range; the method comprises the following steps of: obtaining a sample; determining whether the frequency signal in the second frequency range generates harmonic interference with the frequency signal in the first frequency range or not, and if yes, determining target frequency ranges corresponding to different user equipment by the first scheduler according to a limit default value X and at least one frequency starting value Z sent by the second scheduler; and for different user equipment, the first scheduler receives and transmitsdata in other frequency ranges except the target frequency range corresponding to the user equipment 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...

Problems solved by technology

However, if the RF hardware design of the user equipment 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 user equipment transmits in the entire low-frequency uplink, the downlink data is not scheduled in the entire high-frequency downlink, but this solution will cause the user equipment to uplink and downlink. Scheduling opportunities are directly halved, so that the downlink and uplink rates of single-user equipment and the system as a whole are severely reduced
