Embodiment Construction

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts all belong to the protection scope of the present invention.

[0026] Before elaborating the content provided by the present invention in detail, the influence of harmonic interference and intermodulation interference is firstly introduced.

[0027] For harmonic interference, the amplitude of the third and above harmonics is small, and the impact can be ignored. The embodiment of the present invention mainl...

Abstract

The embodiment of the invention provides a static interference coordination method and device in a 5G communication system. The method comprises: in a 5G non-independent networking scene, when an LTElink and an NR link receive and transmit signals at the same time, performing uplink and downlink scheduling on an EN-DC terminal at an LTE side or an NR side by using a pre-configured frequency bandwhich does not generate self-interference or is not interfered by self; and for the non-EN-DC terminal, performing uplink and downlink scheduling on the LTE side or the NR side by using the frequencyband which generates self-interference or is subjected to self-interference. According to the embodiment of the invention, the EN-DC users are scheduled according to the pre-configured frequency bandswhich do not generate self-interference and are not influenced by the self-interference in the self-interference scene, so that the self-interference can be effectively avoided.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a static interference coordination method and device in a 5G communication system. Background technique [0002] In the future, 5G NR (New Radio) terminals will support multiple standards such as LTE (Long Term Evolution, long-term evolution) and NR, as well as the simultaneous operation of multiple standards on multiple carriers. as in 5 th -GenerationNSA (None Stand Alone non-independent) networking scenario, when the LTE and NR transceiver links work at the same time, there will be self-interference of the transceiver signals between multiple frequency bands. According to the source of interference to the terminal, the interference is divided into two types: harmonic interference and intermodulation interference. [0003] Harmonic interference: When the input is a single tone signal f1, the output signal contains high-order harmonic compone...
