Description

technical field

The invention relates to the field of communication technology, in particular to an interference detection method, an adaptive adjustment method and a wireless communication device of a wireless communication device.

Background technique

Wireless communication equipment, such as base stations, are often subject to external interference during operation. External interference will directly cause problems in the equipment itself and directly affect the service quality of the equipment. For example, when the base station is subjected to external interference, it will directly cause problems such as user rate drop and access failure. Therefore, the external interference of the wireless communication device needs to be detected in time, and the wireless communication device should be adapted and adjusted according to the interference.

Taking the base station as an example, the existing interference detection and equipment adaptation and adjustment process usually first detect the KPI (Key Performance Indicators, key performance indicators) of the wireless network, such as the call drop rate, etc., to discover service abnormalities; Gradually check various influencing factors in the network, such as transmission network failures, hardware equipment failures, and air interface interference. If air interface interference is found, manually adjust the operating parameters of the base station to minimize the impact on services.

However, in the interference detection and equipment adjustment method of artificial passive response described above, it takes a long time to manually locate the interference and adjust the equipment, especially for sudden interference, even when the interference has not been located, the interference has disappeared. Therefore, this method The response to interference is too slow, the efficiency is too low, and the problems caused by interference cannot be dealt with in time.

Detailed ways

In order for those skilled in the art to further understand the features and technical contents of the present invention, please refer to the following detailed description and accompanying drawings of the present invention. The accompanying drawings are provided for reference and illustration only, and are not intended to limit the present invention.

The technical solutions of the present invention will be described below in conjunction with the drawings and embodiments.

Referring to FIG. 1 , it is a flowchart of an interference detection method for a wireless communication device provided by an embodiment of the present invention.

The method can include:

Step 101: Sampling the uplink signal transmitted by the wireless communication device at each preset time point to obtain sampled data.

In this embodiment, this step may be to sample the uplink signal in the uplink service channel sent by the wireless communication device. This method may interfere with the normal uplink service. Of course, it may also be to establish a channel independent of the uplink service channel. To obtain the uplink signal transmitted by the wireless communication device. Wherein, the sampling process of the uplink signal can be performed by the ADC of the radio frequency module of the wireless communication device, or a new sampling unit (which can be another ADC) can be added in the radio frequency module to perform the sampling process. The sampling unit can also be arranged outside the radio frequency module. As long as the sampling of the uplink signal of the wireless communication device can be realized. Specifically, for example, when the wireless communication device is a mobile phone, the uplink analog signal sent by the mobile phone at the UU interface may be sampled to obtain sampled data. The time point for sampling the uplink signal can be set according to the required sampling frequency, which is not limited here.

Step 102, transforming the sampling data respectively to generate spectrograms at each preset time point.

Specifically, Fourier FFT transform may be performed on the sampling data of the uplink analog signal collected at each preset time point to obtain a frequency spectrum diagram at each preset time point. This step may be to perform Fourier transform collectively after obtaining a plurality of sampled data, or to perform Fourier transform every time sampled data is obtained.

Step 103, compare the frequency spectrum diagrams at each preset time point, and determine the interference mode received by the wireless communication device based on changes in the frequency spectrum in the frequency spectrum diagrams.

In this embodiment, after obtaining the spectrograms of the sampling data at each preset time point, by comparing the spectrograms at each preset time point, changes in the spectrum can be obtained, such as changes in frequency peaks, changes in spectrum waveforms, etc. Furthermore, it can be determined whether the wireless communication device is interfered within the period corresponding to each preset time point, and the interference method. For the specific process, please refer to the description of the subsequent embodiments.

Compared with the method of manual passive response troubleshooting in the prior art, the embodiment of the present invention samples the uplink signal sent by the wireless communication device itself, and then obtains the spectrum diagram, and determines the interference mode according to the spectrum diagram, which greatly shortens the The detection and response time to external interference is convenient for follow-up and timely adjustment to reduce interference and reduce problems caused by interference.

Referring to FIG. 2 , it is a flowchart of an adaptive adjustment method for a wireless communication device according to an embodiment of the present invention.

The adaptation method may include:

Step 201: Sampling the uplink signal transmitted by the wireless communication device at each preset time point to obtain sampled data.

In this embodiment, at each preset time point, the ADC of the radio frequency module samples the uplink analog signal in the RF-RX receiving channel of the radio frequency module to obtain sampling data at each preset time point.

In step 202, Fourier transform is performed on the sampled data respectively to generate a spectrogram at each preset time point.

The frequency spectrum map can cover the frequency range currently used by the cell, as well as a certain range of sideband spectrum. In a specific implementation process, the frequency spectrum diagram may be presented through a user interface for use by maintenance personnel.

Step 203: Compare the frequency spectrum diagrams at each preset time point, and if there is a sudden change in the frequency peaks within the uplink frequency range in the frequency spectrum diagrams, it is determined that the wireless communication device is interfered by the entire frequency band of the time-domain burst.

In this step, compare the spectrograms at each preset time point. Of course, the uplink frequency ranges in each spectrogram are the same. In the frequency range of the uplink in the frequency spectrum, the peak values corresponding to the same frequency all change abruptly, which means that the wireless communication device receives the interference of the entire frequency band in a time-domain burst.

In this embodiment, the uplink signal is sampled according to a relatively small interval, such as greater than 1FPS (Frame Per Second: the number of data frames per second), and then the spectrogram of the sampled data at each time point is obtained, such as the nth ( n is a positive integer) at time n, the frequency spectrum at n+1FPS time, the frequency spectrum at n+2FPS time..., the frequency spectrum at n+nFPS time, where n is a positive integer. After obtaining the spectrograms in the nFPS time period, compare the spectrograms. If a certain spectrogram, such as the spectrogram at the n+5th FPS time, all frequencies in the frequency range (f1～ The peak value of fn) changes suddenly compared to the peak value corresponding to the same frequency (f1～fn) in other spectrograms (taking one of the frequencies as an example, such as the peak value of frequency f1 in the spectrogram at the n+5FPS moment is relative to other frequencies If the peak value of frequency f1 in the figure changes abruptly), it means that the wireless communication device is subject to burst interference in the time domain at the n+5 FPS time, and the entire frequency band is subject to interference.

In order to facilitate the display of changes in the spectrogram, for UMTS, the WATERMARK method can also be used to determine whether there is corresponding interference by comparing the highest value of the frequency within a period of time. Among them, WATERMARK is to keep the maximum value of updated data for data that changes with time In the WATERMARK data curve, if the maximum peak value of a certain frequency deviates from the normal value, or the maximum peak value of a certain frequency is much larger than the corresponding peak values of other frequencies, it means that there is an interference source at this frequency.

In another embodiment of the present invention, if after obtaining the spectrogram within the above nFPS time period, it is found by comparison that it is not the frequency peak in a certain spectrogram that suddenly changes, but the spectrogram within a period of time, such as n+2FPS In the spectrogram from time to n+8FPS, the peak values of all frequencies in the uplink frequency range continue to change, that is, the peak values of the same frequency in the uplink frequency range in the spectrogram at each time are different in each spectrogram , it means that the wireless communication device has been interfered by the time-continuous type from the n+2 FPS time to the n+8 FPS time, and the entire frequency band has been interfered.

Step 204, start the anti-interference scheduling algorithm, and adjust the parameters of the anti-interference scheduling algorithm, so as to increase the uplink transmission power of the wireless communication device and reduce interference.

In this embodiment, once it is determined that the wireless communication device is subject to burst interference in the time domain and the entire frequency band is subject to interference, the anti-interference scheduling algorithm can be triggered to start, and the parameters of the anti-interference scheduling algorithm can be adjusted to increase The uplink transmission power of wireless communication equipment reduces interference. Specifically, the wireless communication device estimates the actual load based on information such as the amount of uplink data, and compares it with the total uplink power. If the difference is large, it is considered that there is interference, and then adjusts the parameters of the anti-interference scheduling algorithm to increase the uplink transmission power. The impact of interference.

In the embodiment of the present invention, the wireless communication device itself samples the uplink signal to obtain a spectrum diagram, and compares the spectrum diagram to determine the interference mode, which greatly shortens the detection time of external interference, and further reduces the influence of interference through adaptive adjustment .

Referring to FIG. 3 , it is a flow chart of another adaptive adjustment method for a wireless communication device according to an embodiment of the present invention.

The adaptation method may include:

Step 301: Sampling the uplink signal transmitted by the wireless communication device at each preset time point to obtain sampled data.

In this embodiment, an ADC is added in the radio frequency module, and the newly-built independent receiving channel in the radio frequency module receives and samples the uplink analog signal through the newly added ADC to obtain sampling data, wherein, the independent receiving channel and the radio frequency module The original uplink business channel is independent.

In step 302, Fourier transform is performed on the sampled data respectively to generate a spectrogram at each preset time point.

The frequency spectrum map can cover the frequency range currently used by the cell, as well as a certain range of sideband spectrum.

Step 303 , comparing the frequency spectrum diagrams at each preset time point, and if the frequency spectrum waveform appears within the preset range around the uplink frequency range in the frequency spectrum diagram, it is determined that the wireless communication device is subject to sideband interference.

Still taking the spectrogram at the nth moment obtained in the nFPS time period, the spectrogram at the n+1FPS moment, the spectrogram at the n+2FPS moment..., the spectrogram at the n+nFPS moment as an example, in this embodiment , mainly to judge whether there is interference in the sideband area of each spectrum graph.

Wherein, the sideband refers to a range adjacent to the left and right sides of the uplink frequency range on the frequency coordinate of the frequency spectrum diagram. For example, if the uplink frequency range is 2010MHZ-2015MHZ, it can be considered that 2009.5MHZ-2010MHZ and 2015.0MHZ-2015.5MHZ are sidebands. In this embodiment, the sideband area within the 0.5 MHz range (preset range) around the frequency range currently used for uplink is continuously detected to determine whether there is sideband interference. The preset range of 0.5MHZ can also be set according to needs.

Each spectrum diagram obtained in the above-mentioned nFPS time period all includes the sideband area within the 0.5MHZ range, by comparing whether the spectrum waveform appears in the sideband area in each spectrum diagram, to determine whether there is sideband interference, if the If a waveform appears in the sideband region, that is, a peak or a trough appears, it can be determined that the wireless communication device has sideband interference.

Step 304, shrinking the uplink bandwidth of the wireless communication device.

If there is sideband interference, in this step, trigger the contraction of the uplink usage bandwidth. For example, shrink the uplink bandwidth from 5MHZ to 4.4MHZ and 4.2MHZ to reduce the impact of sideband interference. Specifically, you can use small intervals for transmission and reception, and control the transmission bandwidth to 4.4MHZ during downlink transmission, and the uplink part filters the part larger than 4.4MHZ to remove the part outside the range of 4.4MHZ before processing.

In the embodiment of the present invention, the wireless communication device itself samples the uplink signal to obtain a spectrum diagram, and compares the spectrum diagram to determine the interference mode, which greatly shortens the detection time of external interference, and further reduces the influence of interference through adaptive adjustment .

In the above adaptation and adjustment embodiment, after the interference is adjusted and reduced, if the interference disappears is subsequently detected, then the parameters of the wireless communication device can be restored to the state before the adjustment. In addition to being applicable to wireless devices such as base stations and mobile phones, the methods in the above embodiments can also be used on all other wireless devices with air interface interference, such as GSM, CDMA, LTE, TD-SCDMA, WIMAX, microwave devices and other wireless devices.
