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

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 resource scheduling system, and the resource scheduling system includes a first scheduler and a second scheduler, the first scheduler transmits and receives data in the first frequency range, and the second scheduler transmits and receives data in the second frequency range To transmit and receive data, the method includes: determining whether harmonic interference occurs between the frequency signal in the second frequency range and the frequency signal in the first frequency range, and if so, the first scheduler according to the second scheduler The sent limit default value X and at least one frequency start value Z determine target frequency ranges corresponding to different user equipments; for different user equipments, the first scheduler divides the first frequency range from the user equipment Sending and receiving data in other frequency ranges outside the corresponding target 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...
