Embodiment 1

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

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

[0034] The terminal 10 measures the RS (Reference Signal, reference signal) of each RB of the air interface resource used by the base station 20 for downlink data transmission;

[0035] The terminal 10 calculates the SINR (Signal to Interference plus NoiseRatio, signal to interference plus noise ratio) of the RS of each RB;

[0036] The terminal 10 judges whether it is interfered by a radio station signal according to the SINR of the RS of each RB.

[0037] Among them, measuring the RS (Reference Signal, reference signal) of each RB and calculating the SINR (Signal to Interference plus Noise Ratio, signal to interference plus noise ratio) of the RS of each RB can be based on the existing technology of State Grid LTE implement. If the RB is interfered by t...

Abstract

The invention discloses a method and system for detecting interference caused by a radio station. The method includes: a terminal receives downlink data transmission from a base station; and the terminal measures the RS of each RB of the air interface resource used by the base station for downlink data transmission. ; The terminal calculates the SINR of the RS of each RB; the terminal judges whether it is interfered by a station signal according to the SINR of the RS of each RB. The invention utilizes the SINR of the RS of each RB in the process of downlink data transmission to determine 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 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...
