Embodiment Construction

[0101] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0102] Generally, the remote interference management RIM scheme of Time Division Long Term Evolution (TD-LTE) requires the OAM system to participate in the configuration management of the reference signal RS transmission and monitoring of the disturbed base station and the disturbing base station. In some scenarios, based on the channel reciprocity of the time division duplex TDD system, it can be considered that the interfering base station is also the disturbed base station. Actively trigger the reference signal RS transmission and monitoring process, but because the interfering base station is not the disturbed base station, that is, the interfering noise IoT of the interfering base station does not show the characteristics of far-end interference, and...

Abstract

The invention provides a method, a device, equipment and a medium for positioning far-end interference, and the method comprises the steps: obtaining an unknown adjacent cell, the distance between which and a base station is greater than a preset threshold value, according to an ANR (Automatic Neighbor Relation) process under the condition that a far-end interference characteristic signal is detected; and executing a process of performing remote interference management RIM on the unknown neighbor cell. According to the scheme of the invention, the automatic neighbor relation ANR process is added before the remote interference management RIM process is executed, the unknown neighbor of which the distance to the base station is greater than the preset threshold value is obtained, the remote interference caused by the atmospheric waveguide is discovered and positioned in an assisted manner, the number of the base stations for monitoring and sending the configuration reference signal RS managed by the OAM system is reduced, and the monitoring efficiency of the remote interference caused by the atmospheric waveguide is improved. The management overhead of the OAM system can be saved, and the power consumption of the base station can be reduced.

Description

technical field [0001] The present invention relates to the field of wireless technology, in particular to a method, device, equipment and medium for locating far-end interference. Background technique [0002] In the inland areas at the turn of spring and summer, summer and autumn, or in the coastal areas in winter, the phenomenon of atmospheric ducting (Atmospheric Duct) is prone to occur. In the troposphere, there is a layer where temperature inversion or water vapor decreases sharply with height, which is called the waveguide layer. Most of the radio wave radiation will be confined in this layer, and ultra-long-distance (such as tens to several 100 km) spread. [0003] Time Division Duplexing (Time Division Duplexing, TDD) system uses uplink and downlink time division multiplexing, and prevents downlink from interfering with uplink by setting a guard period (Guard Period, GP). When the atmospheric waveguide occurs, the downlink signal of the remote base station (that i...
