Embodiment Construction

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are only some of the embodiments of the present disclosure, not all of them. The following description of at least one exemplary embodiment is merely illustrative in nature and in no way intended as any limitation of the disclosure, its application or uses. Based on the embodiments in the present disclosure, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present disclosure.

[0043] The inventor found through research that not all base stations in the entire network are interfered by the atmospheric waveguide, and the disturbed base stations are not interfered by the atmospheric waveguide every day or every moment. However, once the base s...

Abstract

The invention provides an interference suppression method, system and device and a computer readable storage medium, and relates to the technical field of wireless communication. The interference suppression method comprises the following steps that: a disturbed base station performs interference detection by using a synchronization signal sent by an interference application base station; the disturbed base station reads the identifier of the interference application base station, and determines the propagation time delay from the interference application base station to the disturbed base station according to the position of the related peak value obtained by interference detection; the disturbed base station sends propagation time delay from the interference application base station to the disturbed base station to the disturbed base station according to the identifier of the interference application base station; the interference application base station determines a interference application base station downlink time slot causing interference to the disturbed base station uplink time slot according to the propagation time delay; and the interference application base station sets the OFDM symbol in the downlink time slot of the interference application base station as a protection time slot. The atmospheric waveguide interference in the TDD mobile communication system can besuppressed, so that the operation efficiency and the user experience of the TDD mobile communication system are improved.

Description

technical field [0001] The present disclosure relates to the technical field of wireless communication, and in particular to a method, system, device and computer-readable storage medium for suppressing interference. Background technique [0002] Atmospheric waveguide interference also refers to TDD (Time Division Duplexing, Time Division Duplex) far-end interference. Since atmospheric duct interference is a major problem faced by TDD macro network operations, the research and standardization of atmospheric duct interference management has attracted much attention. [0003] When atmospheric waveguide interference occurs, the downlink signal of the far-end base station of the TDD wireless communication system still has a high intensity after hundreds of kilometers of ultra-long-distance propagation, which may cause serious interference to the uplink reception of the near-end base station. Atmospheric duct interference has the following characteristics: [0004] (1) It mainl...
