Problems solved by technology

[0005] However, in the 5G non-independent deployment scenario, both LTE and NR need to transmit uplink. The interference of second-order intermodulation stipulated in the current standard will cause the sensitivity to drop by more than 20dB. If it is not optimized, it will have a serious impact on network coverage and downlink rate.

Embodiment Construction

[0068] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be more thoroughly understood, and will fully convey the scope of the present invention to those skilled in the art.

[0069] The embodiments of the present invention are aimed at the prior art, in the case of serious interference of frequency bands or channel combinations, the network adopts a time-division scheduling method, so that the UE transmits uplink time-divisionally in the frequency bands of LTE and NR, and only performs uplink on one frequency band at the same time. sent to avoid interference.

Abstract

Embodiments of the present invention provide a terminal scheduling method, network equipment, and terminal equipment, wherein the scheduling method includes: sending scheduling information to the terminal, where the scheduling information is used to enable the terminal to time-divide between at least two frequency bands where interference occurs. way to send data. The scheme of the present invention performs uplink transmission on two frequency bands by means of time division, so as to avoid the problem of self-interference at the terminal.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a terminal scheduling method, network equipment and terminal equipment. Background technique [0002] In 5G, the non-standalone deployment method needs to use the LTE network and the NR network for dual connection, which is one of the important scenarios for the initial deployment of 5GNR. In the operation of the NSA (non-access stratum), the terminal is required to maintain dual-frequency and dual-transmission in the uplink, that is, maintain dual-transmission in the LTE frequency band and the NR frequency band. However, due to nonlinear factors such as radio frequency devices, the double transmission of the terminal in the two frequency bands will cause intermodulation interference. The intermodulation interference is formed by the combination of multiple components at the transmitting end. For example, the second-order intermodulation is f2- f1, the thir...
