Remote interference management method

Abstract

The invention discloses a remote interference management method, which accurately detects whether remote interference exists or not by using double reference signals in an initial state, and improvesthe accuracy and credibility of a detection result. Simultaneously, after receiving the corresponding remote interference reference signal, the interfered gNB stops transmitting the own remote interference reference signal. According to the method, the situation that the double reference signals are sent at the same time is avoided to a certain extent, the consumption of communication resources for remote interference suppression is greatly reduced, the expenditure of an RIM framework is reduced, and on the premise that the double reference signals are used, the interaction of the reference signals can be reduced in the framework process, so that the expenditure of system resources is reduced.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method for constructing a remote interference management framework. Background technique [0002] Under certain weather conditions, electromagnetic waves propagating in the atmosphere, especially the troposphere, are affected by atmospheric refraction, and their propagation trajectories will be bent to the ground. Some of the electromagnetic waves will be trapped in a thin atmosphere with a certain thickness, which is similar to the propagation of electromagnetic waves in a metal waveguide. This phenomenon is known as the propagation of electromagnetic waves through atmospheric ducts (also known as tropospheric ducts). [0003] The atmospheric waveguide phenomenon will cause the signal transmitted by the gNB to propagate hundreds of kilometers away with a small path loss, thereby causing interference to the remote gNB. In TD-LTE, due to the existence of...

Problems solved by technology

For the reference signal RIM framework, the monitoring of long-range interference disappearance is mostly based on the "disappearance" of the reference signal attached by the interfered party monitored by the interferer gNB, which cannot reflect the real remote interference channel situation (that is, from the interferer gNB to the victim interfering gNB), which may lead to misjudgment in the channel environment of asymmetric interference, resulting in deviations in interference adjustment

[0009] For the RIM framework with dual reference signals, the reference signal from the interferer gNB to the interfered gNB can effectively judge the existence of long-range interference, but the two reference signals in the long-range interference suppression structure will occupy the corresponding communication resources at the same time, and the Will greatly increase the overhead of the RIM framework
