Description
Technical Field
The invention relates to the technical field of antenna correction, in particular to an antenna radio frequency channel warning method and device.
Background
The antenna calibration function is one of important functions in an LTE Massive MIMO (Long Term Evolution Massive Multiple Input Multiple Output) system. Because the number of the antennas of the LTE Massive MIMO system is large, the amplitude-phase characteristics of each antenna channel are very important, and thus the performance of the system is directly determined by the quality of the antenna correction function.
The essence of the antenna calibration is to track and compensate the amplitude and phase characteristics of the channels, and reduce the relative error between the channels by the idea of closed-loop feedback to meet the performance requirement. The method comprises the steps of injecting a reference signal, comparing a received signal with channel characteristics with the reference signal after the signal passes through an active network and a passive network which need to be corrected, thereby correcting errors and finally realizing the consistency of the amplitude-phase characteristics of the channels.
For an LTE Massive MIMO base station, in a commercial process, with the influence of multiple aspects such as longer running time and external environment interference, a scene that some antenna channels of the base station are abnormal may occur. If one channel is abnormal, the conventional antenna correction cannot pass, so that the correction weight cannot be compensated to the channel, and the service shaping effect is influenced finally. Research shows that for a small number of channels with abnormal (assuming that the maximum tolerance abnormal number is N), the service can still be normally performed, and the invalid abnormal channels can be eliminated by an antenna rank reduction method, and the processes of antenna correction, weight compensation and the like can still be initiated by using the effective channels.
In the actual commercial process, after the LTE base station normally establishes a cell, uplink and downlink antenna calibration is automatically initiated every period T to ensure effective monitoring of the radio frequency channel of the base station and guarantee the wireless performance of the base station. The antenna calibration is divided into uplink antenna calibration, uplink antenna calibration and downlink antenna calibration.
In the application process of antenna correction and antenna rank reduction, the following problems exist:
1. the external environment interference causes the radio frequency channel of the base station to be abnormal, the base station reports an alarm after detecting the radio frequency channel to be abnormal, external field maintenance personnel or local side mistakenly think that the hardware is damaged after seeing the relevant alarm, unnecessary troubles can be caused, and the system performance can be influenced if the antenna calibration fails in the scene.
2. The base station reports an alarm after detecting the radio frequency channel abnormality, but the performance of the base station cannot be influenced by a few channel abnormalities. The field maintenance personnel or bureau can mistakenly think that the hardware is damaged after seeing the relevant alarm, which causes unnecessary trouble, and the system performance can be influenced if the scene antenna correction fails.
3. For the scene of antenna calibration failure, it is impossible to locate which channels are abnormal.
