Project 2:
5G communication base station causing interference with C-band satellite earth station
1.Background
The 5G NR base station based on 3.5 GHz band uses the frequency range of 3 400 MH - 3 600 MHz, of which 3 400 MHz - 3 500 MHz is used by Telecom and 3 500 MHz - 3 600 MHz is used by Unicom. 3 600 MHz is used by Unicom. Currently, the 3 400 MHz-4 200 MHz spectrum is used by satellite earth receiving stations, and the 5G NR base stations in the 3.5G frequency band will cause same-frequency interference, neighbouring-frequency interference, or blocking interference.


2. Interference Overview
The satellite signals of the C-band of a city's satellite earth receiving station have been interfered with.



3. Allocate Interference Locating and Testing Process
Jointly with experts from various parties, the test plan is initially diagnosed to be related to 5G NR, and the test plan is determined as follows: NR related, to determine the test programme: coupled to connect the earth station antenna connecting line, linked to the use of Allocate 5G interference sweeper input, 5G TOP N decoding test (PCI/SSBIDEX/RSSI, etc.), decoding out the impact of the earth station, according to the order of the strength of the weak, and then one by one exclusion to eliminate the impact of the method.



4. Analysed and confirmed the interference through 5G NR CELL ID decoding tests.

Decoding analysis: Through decoding, we know that TOP1: PCID (432) and SSBInex (2) China Telecom 5G
NR interferes seriously with C fluctuating satellite signals




5. Solution
Solution:Installation of band-pass filter, the satellite signal interference is eliminated.
