Embodiment 1

[0032] This embodiment provides a method for detecting interference caused by radio stations, such as figure 1 shown, including:

[0033] The base station 10 receives the uplink data transmission from the terminal 20;

[0034] The base station 10 measures the DMRS (Demodulation Reference Signal, demodulation reference signal) of each RB of the air interface resources used by the terminal 20 for uplink data transmission;

[0035] The base station 10 calculates the SINR (Signal to Interference plus Noise Ratio, signal to interference plus noise ratio) of the DMRS of each RB;

[0036] The base station 10 judges whether it is interfered by radio signals according to the SINR of the DMRS of each RB.

[0037] Among them, measuring the DMRS (Demodulation Reference Signal, demodulation reference signal) of each RB, and calculating the SINR (Signal to Interference plus Noise Ratio, signal to interference plus noise ratio) of the DMRS of each RB can be based on the national network LT...

Embodiment 2

[0042] Based on the method for detecting interference caused by radio stations provided in Embodiment 1, this embodiment provides a system for detecting interference caused by radio stations, such as figure 2 As shown, it includes a terminal 20 and a base station 10; the base station includes:

[0043] The receiving module 11 is used to receive the uplink data transmission of the terminal 20;

[0044] A measurement module 12, configured to measure the DMRS of each RB of the air interface resource used by the terminal 20 for uplink data transmission;

Abstract

The invention discloses a method and system for detecting interference caused by a radio station. The method includes: a base station receives an uplink data transmission of a terminal; the base station measures the DMRS of each RB of the air interface resource used by the terminal for uplink data transmission ; The base station calculates the SINR of the DMRS of each RB; the base station judges whether it is interfered by a station signal according to the SINR of the DMRS of each RB. The invention utilizes the SINR of the DMRS of each RB in the process of uplink data transmission to judge whether the RB is interfered by the signal of the radio station, can realize the detection of the interference caused by the radio station, and find out the location of the specific interference of the radio station.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and system for detecting interference caused by radio stations. Background technique [0002] In the current national power communication system, wireless communication is mostly based on radio communication equipment, and the power system is relying on these radio stations to ensure the communication of the power system to maintain the safe operation of the national grid. At the same time, the national power system is also planning a new generation communication system for the national power system based on the current broadband system. [0003] This will lead to the coexistence of radio stations and new-generation broadband communication technologies in the State Grid for a period of time in the future, and due to the unique advantages of radio stations such as confidentiality, given the importance of State Grid to national security, this trend will last...
