Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The NR TDD network commonly uses 64/32 channel AAU antenna to obtain the beam forming gain, if the AAU antenna is blocked or partially blocked, the whole coverage performance of the NR TDD cell is affected
The traditional method for judging whether the base station antenna is blocked is to carry out visual inspection judgment from a network optimization engineer to the near end of the antenna or comprehensively judge whether the antenna is blocked according to road tests and base station antenna azimuth angles.
However, the above-mentioned determination method has high dependency on network optimization engineers, is often easily affected by subjective factors, and may have differences in the analysis process of different people, thereby resulting in inaccurate determination results. Moreover, the method is time-consuming and labor-consuming, cannot be widely unfolded, and is low in efficiency.
In order to solve the problems, the invention firstly configures a specific beam for the antenna to be detected according to the beam configuration condition of the antenna to be detected, then calculates the average signal intensity of each antenna array subgroup on the specific beam, and judges that the antenna to be detected is blocked if the difference value between the average signal intensities exceeds a first preset threshold value, thereby realizing the automatic judgment of the blocking condition and ensuring the accuracy of the result.
In order to better understand the above technical solution, exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
An embodiment of the present invention provides an antenna state detection method, and referring to fig. 1, fig. 1 is a schematic flow chart of a first embodiment of an antenna state detection method according to the present invention.
In this embodiment, the method for detecting an antenna state includes:
step S11: configuring a specific wave beam for an antenna to be detected according to the wave beam configuration condition of the antenna to be detected;
it can be understood that the beam configuration represents the distribution of the radiation or receiving capability of the antenna in different directions, and in this scheme, mainly refers to a Single Side Band (SSB) beam configuration, that is, a configuration that uses a Single side band modulation technique to form a beam so as to implement signal transmission in a specific direction. The method specifically comprises the parameters of horizontal half power angle, vertical half power angle, main lobe width, side lobe suppression and the like, and the distribution situation of the radiation or receiving capacity of the antenna in different directions can be known through the parameters, so that proper antenna beam configuration can be selected subsequently, and specific application requirements and environment conditions can be met.
Optionally, determining a cell global identity (Cell Global Identifier, CGI) of the NR TDD cell in which the antenna to be detected is located, i.e. uniquely identifying a cell throughout the world, the specific composition of the CGI includes: MCC (country code), MNC (network code), NCI (NR Cell global identity), NCI being composed of gNB ID and Cell ID.
Further, an NR TDD cell antenna information database is preset, in which the antenna information of all NR TDD cells is recorded, so that the global identifier of a cell can be used as a keyword, the antenna information of the current cell can be queried in the database, and then a finer beam configuration condition is obtained from the antenna information.
It should be noted that NR TDD cells typically use integrated massive array AAU antennas, utilizing multi-antenna technology and space division multiplexing technology, and specifically NR TDD cells typically use 64/32 channel AAU antennas.
Besides the scheme, the beam configuration condition of the antenna to be detected can be obtained in other modes, such as using professional simulation and emulation software, and the radiation or receiving mode of the antenna is calculated through inputting parameters such as the geometric structure, the material property and the working frequency of the antenna, and the beam configuration information is provided; for example, the antenna test device and the measuring instrument are used to perform actual test and measurement on the antenna to obtain more accurate beam configuration information, and the common test method includes antenna scan test and antenna array measurement, and the embodiment is not limited specifically.
It will be appreciated that the 5G beam mainly relates to an SSB beam and a CSI-RS beam (Channel State Information Reference Signal Beam ), the former being a broadcast beam and the latter being a control beam, the weights of both beams employing static weights.
Alternatively, the antenna weight, i.e., the quantized representation of each channel of the antenna after applying a specific excitation signal, including but not limited to polarization direction, beam width, beam direction, etc., is determined based on parameter information therein, such as horizontal half-power angle, vertical half-power angle, main lobe width, side lobe suppression, etc., known as the existing beam configuration of the antenna to be detected. Therefore, by adjusting the antenna weight of the 64/32 channel of the antenna, the synthesis of the service beam can be realized, and the CSI-RS beam is configured for the antenna to be detected.
Optionally, step S11 includes:
step S111: determining a horizontal half-power angle of an antenna to be detected according to the beam configuration condition of the antenna to be detected;
step S112: if the horizontal half-power angle meets the initial configuration angle, configuring a horizontal beam for the antenna to be detected;
step S113: and if the horizontal half-power angle does not meet the initial configuration angle, configuring a vertical beam for the antenna to be detected.
It will be appreciated that there may be multiple antennas within the NR TDD cell and that each antenna is in a different environment, and therefore external environmental factors need to be considered when setting up the configured SSB beam.
Alternatively, the beam configuration of the antenna to be detected is known, and the horizontal half-power angle of the antenna to be detected is determined from the beam configuration, wherein the horizontal half-power angle of the antenna refers to the width of the main lobe of the antenna in the horizontal direction, and the main lobe is deviated from the maximum gain position of the main lobe to two sides, and reaches an angle range corresponding to the point where the gain is reduced by 3 dB. The horizontal half-power angle is an important parameter that measures the width of the radiating or receiving main lobe of the antenna, and characterizes the radiating or receiving capability of the antenna in the horizontal direction.
It can be appreciated that the NR TDD cell 64/32 channel AAU antennas support SSB beam configuration in horizontal and vertical directions as follows:
SSB horizontal 8 beams are used as the horizontal plane base coverage, and the initial configuration angles, such as 65 degrees and 90 degrees, are set for the general horizontal plane, 65 degrees are recommended for dense urban interference scenes, 90 degrees are recommended for common wide coverage scenes, and more edge users can be absorbed than 65 degrees.
The SSB vertical 1+X beams are mainly used for covering vertical buildings, wherein the 1 beam inherits parameters such as the decline of the original horizontal 8 beams and the like and is used for basically covering roads and floors, and the X beams are used for configuring 1-3 SSBs as required according to building heights, building standing distances and the like and serve as the vertical beams to cover the buildings.
Based on the above understanding, if the horizontal half power angle of the current NR TDD cell meets the initial configuration angle, that is, 65 degrees or 90 degrees, configuring an SSB horizontal 8 beam for the antenna to be detected of the NR TDD cell; conversely, if the horizontal half-power angle does not satisfy the initial configuration angle, the SSB vertical 1+x beam is configured for the antenna to be detected, and x=1, 2, 3, etc. may be set according to the actual situation.
According to the horizontal half power angle of the antenna to be detected, different application requirements, scene characteristics and other factors are considered, and then the horizontal beam or the vertical beam is selected and configured so as to obtain the best signal coverage and performance, so that the signal intensity can be acquired conveniently.
Optionally, step S112 includes:
if the horizontal half power angle meets the initial configuration angle, acquiring the amplitude and the phase of the horizontal port;
adjusting the amplitude and the phase of the antenna to be detected according to the amplitude and the phase of the horizontal port;
optionally, step S113 includes:
if the horizontal half power angle does not meet the initial configuration angle, acquiring the amplitude and the phase of the vertical port;
and adjusting the amplitude and the phase of the antenna to be detected according to the amplitude and the phase of the vertical port.
It can be understood that the main expression mode of the antenna weight is the amplitude and the phase of the port corresponding to each channel of the antenna, and the same antenna uses different weights, so that broadcast beams with different widths can be obtained. Therefore, by adjusting the phase and amplitude distribution of the 64/32 channels of the antenna, the synthesis of the service beam can be realized, and the SSB beam is configured for the antenna to be detected.
Alternatively, if the horizontal half-power angle satisfies the initial configuration angle, the horizontal beam needs to be configured, so the horizontal port amplitude and phase corresponding to the horizontal beam are called out from the database storing the mapping relation between the beam type and the port parameters. Further, the existing amplitude and phase are adjusted based on the horizontal port amplitude and phase. The process of vertical beam is similar and will not be described in detail here.
The beam is configured by adjusting the port amplitude and the phase of the antenna, so that the customization of the beam shape can be realized, the signal focusing effect is improved, the interference and the multipath interference are reduced, the system capacity is increased, and the method has the advantages of high flexibility and adaptability.
Step S12: dividing the antenna array of the antenna to be detected into a plurality of groups, and calculating the average signal intensity of each group on the specific wave beam;
it is understood that the antenna array of the antenna refers to an array composed of a plurality of antennas, and the antenna array may be a linear array, a planar array or a bulk array, and the specific structure and form depend on the application requirements. The linear array is formed by arranging a plurality of antennas on a straight line at a certain interval; the surface array is to arrange the antennas on a plane in a matrix form; the body array distributes the antennas in three dimensions. For easy understanding, the present solution is explained by taking an area array as an example.
Optionally, the antenna array of the antenna to be detected is divided into a plurality of groups, such as 4 groups/6 groups/8 groups, and the adjustment can be performed according to practical situations.
Illustratively, referring to fig. 2, there are 16 columns for the horizontal array and 4 rows for the vertical array, dividing the 64-channel AAU antenna array into 4 groups:
group 1: channels 0/1/2/3, channels 8/9/10/11, channels 16/17/18/19, channels 24/25/26/27;
group 2: channels 4/5/6/7, channels 12/13/14/15, channels 32/33/34/35, channels 40/41/42/43;
group 3: channel 20/21/22/23, channel 28/29/30/31, channel 48/49/50/51, channel 56/57/58/59;
group 4: channel 36/37/38/39, channel 44/45/46/47, channel 52/53/54/55, channel 60/61/62/63.
Illustratively, referring to fig. 3, the horizontal array has 16 columns and the vertical array has 2 rows, dividing the 32-channel AAU antenna array into 4 groups:
group 1: channels 0/1/2/3, channels 8/9/10/11,
group 2: channel 16/17/18/19, channel 24/25/26/27;
group 3: channels 4/5/6/7, channels 12/13/14/15;
group 4: channel 20/21/22/23, channel 28/29/30/31.
Further, calculating the average signal intensity of each group on a specific beam, and in the 64-channel AAU antennas, carrying out group 1, group 2, group 3 and group 4, and carrying out arithmetic average on the RSSI of each group 16 channels to obtain the RSSI average value of each group; in the 32-channel AAU antenna, the RSSI average value of each group is obtained by carrying out the arithmetic average on the RSSI of each group 8 channel in groups 1, 2, 3 and 4.
Optionally, step S12 includes:
step S121: determining grouping conditions according to the number, the positions and the blocking probability of the antenna array of the antenna to be detected;
step S122: dividing the antenna array of the antenna to be detected into a plurality of groups according to the grouping condition;
step S123: and measuring the signal intensity of each group on the specific wave beam for multiple times, and averaging the signal intensity obtained by the multiple times of measurement to obtain the average signal intensity.
It will be appreciated that the channels on the antenna are located at different positions, and that there is a slight difference in the received signal strength, so that to ensure that the average signal strength of the groups obtained later is representative, the equalization of the samples in each group needs to be considered during grouping.
Optionally, the grouping is performed according to the number of antenna elements (e.g. 64 channels) of the antenna to be detected, the positions (central area or edge area) of the antenna elements, the blocking probability (reference may be made to the historical blocking situation), so as to ensure that the expected average signal strengths of each group are substantially consistent.
Further, according to the grouping situation, the antenna array of the antenna to be detected is divided into a plurality of groups. And measuring the signal intensity of all channels on a specific wave beam for multiple times, and counting the total signal intensity of all channels in each group according to the grouping condition, and dividing the total signal intensity by the number of the channels to obtain the average signal intensity.
The equalization of the samples in the groups is considered to ensure the relative equalization of the basic conditions of the samples in each group, so that the uncertainty caused by the difference of the basic conditions of the samples is reduced, other variables which possibly affect the result are controlled more effectively, and the reliability of the subsequent result is improved.
Step S13: and if the difference value between the average signal intensities exceeds a first preset threshold value, judging that the antenna to be detected is blocked.
Alternatively, the difference between the individual packets is calculated, taking 4 packets as an example: group i 2-group 1 |=δ1; group 3-group 1 |=δ2; group i 4-group 1|=δ3; group 3-group 2|=δ4; group i 4-group 2|=δ5; group i 4-group 3|=δ6.
Optionally, a first preset threshold is set, e.g. T 1 =3 dB (other values may be set according to the actual situation), comparing δ1, δ2, δ3, δ4, δ5, δ6 with T 1 Is of a size of (a) and (b).
If the difference between the average signal intensities exceeds a first preset threshold, i.e. δ1, δ2, δ3, δ4, δ5, δ6. Gtoreq.T 1 The difference between the groups is larger and is not in a reasonable error range, so that the antenna to be detected is judged to have blocking, and an antenna engineer can be sent to perform field investigation later.
In one technical scheme provided in this embodiment, according to the beam configuration condition of the antenna to be detected, a specific beam is configured for the antenna to be detected, then the antenna array of the antenna to be detected is divided into a plurality of groups, and the average signal intensity of each group on the specific beam is calculated, if the difference between the average signal intensities exceeds a first preset threshold, it is determined that the antenna to be detected is blocked. Different from the blocking condition judging method, the scheme does not need subjective analysis of a network optimization engineer, and can determine whether the whole antenna is blocked or not only by comparing the average signal strengths of different antenna array sub-groups, so that the accuracy of a judging result is ensured. Compared with manual judgment, the scheme automatically judges according to the preset algorithm and rule, a large number of judgment tasks can be completed in a short time, human resources and time cost are saved, and working efficiency is improved.
Further, referring to fig. 4, a second embodiment of the antenna state detection method of the present invention is presented. Based on the embodiment shown in fig. 1, after the step of determining that the antenna to be detected has a blocking if the difference between the average signal strengths exceeds the first preset threshold, the method includes:
step S21: determining an abnormal group corresponding to the difference exceeding a first preset threshold;
step S22: determining an abnormal channel according to the difference value between the signal intensity of each channel in the abnormal group and the average signal intensity;
step S23: and judging whether the abnormal channel is blocked or not according to the parameter condition of the abnormal channel.
Alternatively, if the difference between the average signal strengths of the packets exceeds a first preset threshold, the corresponding packet is determined to be an abnormal packet.
It will be appreciated that each packet includes a plurality of channels, one of which is blocked, potentially resulting in an anomaly in the average signal strength of the entire packet. Therefore, the signal intensity of the single channel is compared with the average signal intensity of the whole group, and if the difference is too large, the current channel is set as the abnormal channel.
It can be understood that the strength of the signal intensity is not only affected by the shielding condition but also affected by the condition of the channel itself, so that a specific verification of the cause of the abnormality of the abnormal channel is required.
Alternatively, the parameter conditions of the abnormal channel are acquired, and after the influence of the parameters is eliminated, if the signal intensity abnormality still exists, the explanation is due to the blockage of objects such as buildings, terrains and the like. The parameter conditions include, but are not limited to, spacing distances, the positions of different channels are different from the distance between the signal sources, the distances can cause the received signal strengths to be different, and in general, the farther the distance is, the weaker the signal strength is; the positions of different channels of the propagation path can lead to different multipath propagation paths, and the difference of the multipath propagation paths can lead to interference and phase difference of signals so as to influence the strength of the received signals; other environmental disturbances, certain locations may be affected by electromagnetic interference, noise sources, etc., thereby affecting the received signal strength.
In one technical scheme provided in this embodiment, an abnormal packet is determined first, then an abnormal channel is determined according to a difference between signal intensity and average signal intensity of each channel, and then a parameter condition of the abnormal channel is referred to determine whether the abnormal channel is blocked. The method and the device can determine the specific channel causing the abnormal grouping, comprehensively consider the conditions of other factors in the judging process, eliminate the influence of the other factors on the signal intensity as much as possible, and improve the reliability and the accuracy of the judging result of the signal intensity.
Further, referring to fig. 5, a third embodiment of the antenna state detection method of the present invention is proposed. Based on the embodiment shown in fig. 1, after the steps of dividing the antenna array of the antenna to be detected into several groups and calculating the average signal strength of each group on the specific beam, the method includes:
step S31: if the differences among the average signal intensities do not exceed a first preset threshold value, judging that the antenna to be detected is not blocked;
step S32: adjusting grouping conditions of antenna arrays of the antenna to be detected;
step S33: the step of calculating the average signal strength of each group on the particular beam is performed.
Alternatively, if the difference between the average signal strengths is less than a first preset threshold, i.e., δ1, δ2, δ3, δ4, δ5, δ6 < T 1 The difference between the groups is smaller and is within a reasonable error range, so that the antenna to be detected is judged to have no blocking.
Further, the signal intensities received by the antennas in different time periods are different, and the blocking situation of the antennas is not uniform, so that the scheme adopts periodic group replacement to perform performance statistics, and adjusts the grouping situation of the antenna array of the antenna to be detected according to the actual situation, namely adjusts the channel serial numbers contained in the group 1, the group 2, the group 3, the group 4 and the like, and it is noted that the adjusted grouping should also meet the sample balance as much as possible.
And repeatedly executing the calculation of the average signal intensity of each group on the specific beam, and the subsequent judging step, and detecting whether the adjusted group also meets the corresponding condition, so as to realize statistics of different time granularity.
In one technical scheme provided in this embodiment, if the difference between the average signal strengths does not exceed the first preset threshold, it is determined that there is no blocking in the antenna to be detected, and then the grouping of the antenna arrays of the antenna to be detected is readjusted, and the determining step is performed again. The periodic group replacement detection can reduce adverse effects caused by accidental earlier-stage results, improve the reliability and reliability of the results, capture the change condition of the judgment results, discover the shielding problem of the antenna in time and avoid further influencing normal operation.
Further, referring to fig. 6, a fourth embodiment of the antenna state detection method of the present invention is provided. Based on the embodiment shown in fig. 1, before the step of determining that the antenna to be detected has a blocking if the difference between the average signal strengths exceeds a first preset threshold, the method includes:
step S41: acquiring standard signal intensity of the antenna to be detected on the specific wave beam;
step S42: if the difference value between the average signal intensity and the standard signal intensity exceeds a second preset threshold value, judging that the antenna to be detected is blocked;
step S43: and if the difference between the average signal strength and the standard signal strength does not exceed a second preset threshold, executing the step of judging that the antenna to be detected is blocked if the difference between the average signal strength exceeds a first preset threshold.
It will be appreciated that when all channels of the antenna to be detected are blocked, the average signal strength of the groups may be reduced as a whole, in which case anomalies cannot be detected by analysing only the average signal strength differences between the groups.
Alternatively, a suitable standard signal strength may be determined by actual testing and verification, i.e. evaluating and comparing the signal strength of a particular beam in an environment completely free of blocking, before actually determining the antenna blocking situation.
In the actual determination of the antenna blocking situation, the aforementioned standard signal strength auxiliary analysis may be used, and if the difference between the average signal strength and the standard signal strength exceeds a second preset threshold, for example t2=5 dB, it is indicated that all channels of the antenna to be detected are blocked.
Otherwise, if the difference between the average signal strength and the standard signal strength does not exceed a second preset threshold, for example t2=5 dB, further analyzing whether a partial blockage exists, i.e. executing the step of determining that the antenna to be detected is blocked if the difference between the average signal strengths exceeds the first preset threshold.
In one technical scheme provided in this embodiment, the standard signal strength of the antenna to be detected on the specific beam is obtained, then the average signal strength and the standard signal strength are compared, and whether blocking exists is determined according to the difference value of the average signal strength and the standard signal strength. By setting a reasonable range for the average signal intensity, all blocking abnormal conditions are timely and accurately detected, and the integrity of the detection process and the comprehensiveness of the detection result are ensured.

the configuration module is used for configuring a specific wave beam for the antenna to be detected according to the wave beam configuration condition of the antenna to be detected;
