[0002] Under certain meteorological conditions, electromagnetic waves propagating in the atmospheric boundary layer, especially in the near-ground layer, are affected by atmospheric refraction and their propagation trajectory bends toward the ground. When the curvature exceeds the curvature of the earth's surface, part of the electromagnetic wave will be trapped in a thin layer of atmosphere with a certain thickness, just like electromagnetic waves propagating in a metal waveguide. This phenomenon is called atmospheric waveguide propagation of electromagnetic waves. Atmospheric waveguide propagation has a long distance and will cause long-distance co-frequency interference to the fifth-generation mobile communication technology (5G) new radio (NR) communication system.

[0041] When the terms “comprising” and / or “made of…” are used in the present disclosure, it specifies the existence of the stated features, integers, steps, operations, elements and / or components, but does not exclude the existence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof.

It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and this disclosure, and will not be interpreted as having an idealized or overly formal meaning unless explicitly defined in this disclosure.

[0043] In the following embodiments, a disturbed site refers to a site that detects atmospheric duct interference. There may be one or more sites that detect atmospheric duct interference in the same geographical area during the same time period. When there are multiple sites, different disturbed sites execute the same processing flow.

[0044] The interference site refers to the site that applies atmospheric waveguide interference and is the real source of atmospheric waveguide interference.

[0045] The target site refers to the site that monitors the atmospheric waveguide reference signal. It is necessary to identify whether the target site is the real interference source. There can be one or more sites that monitor the atmospheric waveguide reference signal in the same geographical area in the same time period. When there are multiple sites, different target sites execute the same processing flow.

[0046] In the embodiments of the present disclosure, interference source detection, interference detection, and interference notification methods are proposed for atmospheric duct interference, so as to quickly and accurately locate the interference source of the atmospheric duct.

[0047] The application scenario of atmospheric waveguide interference includes a network management server and multiple sites, all of which can establish a communication connection with the network management server. In the case where there is at least one disturbed site affected by atmospheric waveguide interference among the multiple sites, how to accurately locate the disturbing site from other sites is a problem to be solved by the methods provided in the embodiments of the present disclosure.

[0048] The embodiment of the present disclosure provides an interference source detection method, which can be applied to a network management server.

[0049] like Figure 1The figure shows a flow chart of the interference source detection method. The flow chart of the interference source detection method performed by the network management server mainly includes the following steps:

[0050] Step 101: The network management server obtains an atmospheric waveguide reference signal monitored by a target site and an identifier of the target site.

[0051] Among them, the atmospheric waveguide reference signal is also called the remote interference management reference signal (Remote InterferenceManagement Rrference Signal, RimRs), which is usually a RimRs1 signal or an RS-1 signal in related protocols.

[0052] Among them, the identifier of the target site can be the next generation base station (the next Generation Node B, gNB) identity (Identifier, ID), gNB is a 5G base station.

[0053] In some embodiments, the network management server receives the atmospheric waveguide reference signal and the identifier of the target site sent by the target site. The network management server may receive the atmospheric waveguide reference signal and the identifier of the target site sent by multiple target sites, respectively. In this case, the same interference source detection process can be used to perform interference source detection on each target site respectively. Here, the interference source detection process for one target site is used as an example for description.

[0054] Step 102: The network management server determines whether the target site is an interference source according to the atmospheric duct reference signal and the identifier of the target site.

[0055] In some embodiments, the network management server determines whether the target site is an interference source based on the atmospheric waveguide reference signal and the identifier of the target site, including: parsing the atmospheric waveguide reference signal to obtain the identifier of the disturbed site and the parameters for determining the signal transmission distance; based on the identifier of the target site, the identifier of the disturbed site and the parameters for determining the signal transmission distance, determining whether the target site is an interference source of the atmospheric waveguide.

[0056] In some embodiments, the network management server parses the atmospheric waveguide reference signal to obtain the identifier of the disturbed site and the parameters for determining the signal transmission distance, including: parsing the atmospheric waveguide reference signal to obtain the number of the disturbed site in the atmospheric waveguide characteristic sequence in the configuration mapping table, the far-near characterization value of the detection distance, and the sign bit of the detected disturbing site; using the number of the disturbed site in the configuration mapping table as the identifier of the disturbed site, and using the far-near characterization value of the detection distance and the sign bit of the detected disturbing site as the parameters for determining the signal transmission distance.

[0057] In an exemplary embodiment, the network management server parses the RimRs1 signal to obtain the atmospheric waveguide characteristic sequence, and extracts the detection distance characterization value (TddRimDetectOSNum), the symbol bit of the detected interfering site (SymbolIndex), and the number of the disturbed site in the configuration mapping table (RimRsSetID) from the atmospheric waveguide characteristic sequence.

[0058] Table 1 shows the output parameters of the 5G atmospheric waveguide characteristic sequence, and Table 2 shows the meanings of the output parameters of the 5G atmospheric waveguide characteristic sequence. It should be noted that the specific values ​​of the parameters in Tables 1 and 2 are examples.

[0061] Table 2

[0062]

[0063]

[0064] In some embodiments, the network management server determines whether the target site is an interference source of the atmospheric duct based on the identifier of the target site, the identifier of the disturbed site, and the parameter for determining the signal transmission distance, including: determining the transmission distance value of the atmospheric duct reference signal based on the parameter for determining the signal transmission distance; determining the spatial distance value between the target site and the disturbed site based on the identifier of the target site and the identifier of the disturbed site; comparing the transmission distance value and the spatial distance value, and determining whether the target site is an interference source of the atmospheric duct based on the comparison result.

[0065] In some embodiments, the spatial distance value between the target site and the disturbed site is determined according to the identifier of the target site and the identifier of the disturbed site, including: obtaining the spatial location information of the disturbed site according to the identifier of the disturbed site, and obtaining the spatial location information of the target site according to the identifier of the target site; determining the spatial distance value between the target site and the disturbed site according to the spatial location information of the disturbed site and the spatial location information of the target site.

[0066] In an exemplary embodiment, the network management server queries the mapping rules of RimRsSetID and gNodeB ID, obtains the gNodeB ID corresponding to the RimRsSetID extracted from the atmospheric waveguide characteristic sequence, that is, the ID of the disturbed site, obtains the longitude and latitude corresponding to the ID of the disturbed site and the longitude and latitude corresponding to the ID of the target site by searching a preset database, and determines the spatial distance value between the disturbed site and the target site according to the longitude and latitude corresponding to the ID of the disturbed site and the longitude and latitude corresponding to the ID of the target site.

[0067] In some embodiments, the network management server determines the transmission distance value of the atmospheric waveguide reference signal according to the parameter used to determine the signal transmission distance, including:

[0068] When the detection distance characterization value TddRimDetectOSNum is far, the transmission distance value of the atmospheric waveguide reference signal is determined as: the transmission distance value corresponding to the sum of 26 symbol bits accumulated on the basis of the symbol bit of the interference site detected, i.e. SymbolIndex;

[0069] When TddRimDetectOSNum indicates that it is near, the transmission distance value of the atmospheric waveguide reference signal is determined as: the transmission distance value corresponding to the sum of 6 symbol bits accumulated based on the symbol bit of the detected interference site, namely SymbolIndex.

[0070] In an exemplary embodiment, the network management server calculates the transmission distance value of the atmospheric waveguide reference signal according to the RimRs symbol length, which is expressed as L rimrs1 , where TddRimDetectOSNum is represented as Near, the RimRs signal position is the last two Ds of the S slot, and TddRimDetectOSNum is represented as Far, the RimRs signal position is the last two symbols of the second D before the S slot. Assume that TddRimDetectOSNum takes the value 1 to indicate Far, and takes the value 0 to indicate Near. The transmission distance value of the atmospheric waveguide reference signal is expressed as follows:

[0071] If(TddRimDetectOSNum=1)

[0072] L rimrs1 =(SymbolIndex+26)*10.7

[0073] Else if(TddRimDetectOSNum=0)

[0074] L rimrs1 =(SymbolIndex+6)*10.7.

[0075] In some embodiments, the network management server compares the transmission distance value and the spatial distance value, and determines whether the target site is an interference source of the atmospheric duct based on the comparison result, including: obtaining a ratio of the transmission distance value and the spatial distance value; determining whether the ratio belongs to a preset ratio interval; if the ratio belongs to the ratio interval, determining that the target site is an interference source of the atmospheric duct; if the ratio does not belong to the ratio interval, determining that the target site is not an interference source of the atmospheric duct.

[0076] Assume that the spatial distance value is represented by L gps , the transmission distance value is expressed as L rimrs1 , calculate L rims1 With L gps The ratio M is as follows:

[0077]

[0078] Define the confidence interval for the M value [M min ,M max ], determine whether the current M is within the range, and output the detection result of RimRs1. For example, when the confidence interval of the current M is set to [0.3,3] based on historical statistical data, the detection success rate can reach more than 90%.

[0079] In the interference source detection method provided by the embodiment of the present disclosure, the target site monitors the atmospheric waveguide reference signal, which may be a real signal sent by the disturbed site after being interfered by the atmospheric waveguide, or it may be a false detection signal of the target site. The network management server makes a judgment on whether the target site is an interference source, thereby avoiding the problem of high false detection rate caused by directly taking the target site as an interference source, improving the accuracy of interference source positioning, and because the false detection rate is improved, the interference source positioning efficiency and interference detection efficiency are improved, further avoiding the loss of PDSCH resources caused by false detection, and improving wireless service performance.

[0080] In the related technology, the reasons for false detection are roughly as follows: the code domain, time domain, frequency domain and other parameters of all sites of the site equipment manufacturer that turns on the atmospheric waveguide are not aligned across the entire network, resulting in false detection of the RimRs1 signal; the algorithm for detecting the atmospheric waveguide RimRs1 signal cannot achieve complete and correct detection, which will also cause false detection.

[0081] In the disclosed embodiment, the network management server detects the RimRs1 signal and determines whether it is a false detection signal, which can reduce the false detection rate to a great extent.

[0082] The present disclosure also provides an interference detection method, which is applied to a target site, which may be any site that establishes a communication connection with a network management server. Exemplarily, the target site is a site that belongs to the same area as the disturbed site, and there is a possibility that the sites in the area will generate atmospheric waveguide interference with each other.

[0083] like Figure 2 The figure shows a schematic diagram of the interference detection method flow, and the method flow of the target station performing interference detection mainly includes the following steps:

[0084] Step 201: The target site monitors the atmospheric waveguide reference signal.

[0085] In some embodiments, the target site continuously monitors the atmospheric waveguide reference signal when the atmospheric waveguide function is turned on.

[0086] Step 202: The target site sends the monitored atmospheric duct reference signal and the identifier of the target site to a network management server. The atmospheric duct reference signal and the identifier of the target site are used by the network management server to determine whether the target site is an interference source.

[0087] In some embodiments, after the target site sends the monitored atmospheric waveguide reference signal and the identifier of the target site to the network management server, the method further includes: receiving an interference mitigation plan sent by the network management server, and executing the interference mitigation plan; wherein the interference mitigation plan is generated by the network management server when the target site is determined to be an interference source. The generation and specific content of the interference mitigation plan are not the focus of the embodiments of the present disclosure and will not be described in detail.

[0088] In the interference detection method provided by the embodiment of the present disclosure, the target site sends the monitored atmospheric waveguide reference signal and the identification of the target site to the network management server, so that the network management server can judge whether the target site is an interference source based on the atmospheric waveguide reference signal and the identification of the target site, thereby providing the possibility of reducing the false detection rate.

[0089] An interference notification method is also provided in an embodiment of the present disclosure, which is applied to a disturbed site, where the disturbed site is a site that detects atmospheric waveguide interference.

[0090] like Figure 3a The figure shows a flow chart of the interference notification method. The interference notification method of the disturbed station mainly includes the following steps:

[0091] Step 301: The disturbed station starts a timer.

[0092] In some embodiments, before starting the timer, the disturbed station detects atmospheric duct interference or determines that the current time falls within a time period in which atmospheric duct interference occurs.

[0093] Step 302: When the timer has not timed out, the disturbed station continues to send the atmospheric waveguide reference signal.

[0094] In some embodiments, the disturbed station continuously sending the atmospheric waveguide reference signal means periodically sending the atmospheric waveguide reference signal.

[0095] The timing duration of the timer is greater than the sending period of the atmospheric waveguide reference signal.

[0096] Step 303: When the timer times out, the disturbed station stops sending the atmospheric waveguide reference signal.

[0097] In some embodiments, the duration of the timer is pre-configured, and the configuration method includes but is not limited to one of the following situations:

[0098] Case 1: when atmospheric waveguide interference is detected, a first duration is configured for the timer, for example, the first duration is three or four hours;

[0099] Case 2: The area and time period where the atmospheric waveguide interference occurs are statistically obtained. The length of the time period is the second time period. When the current time is about to reach the time period, the timer of each site within the coverage of the corresponding area is set to the second time period. For example, the second time period is one month.

[0100] In the interference notification method provided by the embodiment of the present disclosure, the interfered station continues to send the atmospheric waveguide reference signal when the timer has not timed out, which has the following effects:

[0101] On the one hand, it notifies other stations of possible atmospheric duct interference so that the atmospheric duct interference can be alleviated as soon as possible;

[0102] On the other hand, compared with the existing solutions, the method of controlling the sending duration of the RimRs1 signal through a timer can improve efficiency, avoid repeatedly sending and stopping the RimRs1 signal in a short period of time, and avoid waste of resources. Figure 3bIn the Framework-0 mode of the 3GPP protocol shown, the disturbed station sends a RimRs1 signal after detecting atmospheric waveguide interference --> the disturbing station executes a mitigation plan after receiving the RimRs1 signal --> the disturbed station stops sending the RimRs1 signal if it does not detect atmospheric waveguide interference --> the disturbing station stops executing the mitigation plan --> the disturbed station sends a RimRs1 signal after detecting atmospheric waveguide interference. Compared with the Framework-0 mode, in the embodiment of the present disclosure, the victim base station will not repeatedly send and stop sending the RimRs1 signal within the timing duration of the timer, thereby improving efficiency and avoiding waste of resources;

[0103] On the other hand, compared with the existing scheme, the attacker base station does not need to feedback the signal to stop the transmission of RimRs1, which reduces the signal volume, thus simplifying the stopping process of the RimRs1 signal, reducing the resource overhead occupied by signal transmission (such as the time and frequency resources occupied by transmitting RS-2, etc.), and shortening the atmospheric waveguide detection cycle. Figure 3c In the Framework-1 mode implemented by the 3GPP protocol shown, the disturbing site transmits RS-2 to the disturbed site, and the disturbed site stops sending RimRs1 after receiving the RS-2. In the current Framework-1 implementation based on 20-bit RimRsSetID, the entire RimRs1 transmission cycle takes about 22 minutes. Limited by the detection capability of the physical layer, if all uplink symbols are detected, the required cycle is longer, resulting in poor timeliness of atmospheric duct detection and delayed effectiveness of atmospheric duct mitigation measures. In extreme cases, atmospheric duct mitigation measures are taken only after the atmospheric duct disappears, which not only wastes PDSCH resources, but also fails to achieve a real mitigation effect. In the embodiment of the present disclosure, the RimRs1 signal does not require other signal control to stop sending, and can be controlled by a timer, which reduces the resource overhead occupied by signal transmission to a certain extent and reduces resource waste. In addition, the analysis of RimRs1 is placed on the network management server, which can make full use of the powerful software and hardware capabilities of the network management server, improve analysis efficiency, and shorten the detection cycle.

[0104] In an exemplary embodiment, Figure 4 As shown in FIG. 1 , the interaction process among the network management server, the disturbed site and the target site mainly includes:

[0105] Step 401, the disturbed station determines whether atmospheric waveguide interference is detected, if so, execute step 402, otherwise, return to execute step 401;

[0106] Step 402, the interfered station continues to send the RimRS1 signal and starts the interference detection timer T2;

[0107] Step 403, the target site determines whether the RimRS1 signal is detected, if so, executes step 404, otherwise, executes step 408;

[0108] Step 404, the target site sends the monitored RimRS1 signal to the network management server;

[0109] Step 405, the network management server analyzes whether the RimRS1 signal is a false detection signal, if so, discards the RimRS1 signal and returns to step 403, otherwise, determines that the target site is an interference source, and executes step 406;

[0110] Step 406, the network management server sends an interference mitigation solution to the target site;

[0111] Step 407, the target station executes the interference mitigation solution;

[0112] Step 408: The disturbed station determines whether the timer T2 has timed out. If so, execute step 409; otherwise, return to execute step 403.

[0113] Step 409: The disturbed station stops sending the RimRS1 signal and returns to step 401.

[0114] In an exemplary embodiment, Figure 5 As shown in FIG. 1 , the interaction process between the network management server, the disturbed site and the target site mainly includes:

[0115] Step 501, determining the area where the atmospheric duct occurs and the corresponding time period T by statistically analyzing the currently collected atmospheric duct interference data;

[0116] Step 502, configure a timer T1 for each station in the atmospheric waveguide generation area and start it, so that the station continues to send the RimRS1 signal in the corresponding time period T;

[0117] Any station within the atmospheric ducting area performs the following process:

[0118] Step 503, the station determines whether the RimRS1 signal is detected, if so, execute step 504, otherwise, execute step 508;

[0119] Step 504, the site reports the monitored RimRS1 signal to the network management server;

[0120] Step 505, the network management server analyzes whether the RimRS1 signal is a false detection signal, if so, returns to step 503, otherwise, executes step 506;

[0121] Step 506, the network management server sends an interference mitigation solution to the site that is not a false detection signal;

[0122] Step 507, the station executes the received interference mitigation solution;

[0123] Step 508, the station determines whether the timer T1 has timed out, if so, executes step 509, otherwise, returns to execute step 503;

[0124] Step 509: The station stops sending the RimRS1 signal, and the process ends.

[0125] In an exemplary embodiment, Figure 6a and Figure 6b As shown in the figure, the atmospheric waveguide function configuration of the disturbing site and the disturbed site is in the open state. The interaction process between the disturbing site, the disturbed site and the network management server mainly includes:

[0126] Step 601, the interference site generates atmospheric waveguide far-end interference;

[0127] Step 602, the disturbed station performs atmospheric duct interference detection, and after detecting the atmospheric duct interference, sends a RimRS1 signal according to certain rules;

[0128] Step 603, the interfering site monitors the RimRS1 signal and reports the monitored RimRS1 signal to the network management server;

[0129] Step 604: The network management server analyzes the RimRS1 signal to determine whether the RimRS1 signal is a false detection signal. If the RimRS1 signal is not a false detection signal, it indicates that the interfering site is the interference source, and then sends a corresponding interference mitigation solution to the interfering site. If the RimRS1 signal is a false detection signal, the network management server returns to step 603.

[0130] Step 605: The interfering site executes the interference mitigation solution sent by the network management server.

[0131] The present disclosure also provides an interference source detection system. Figure 7 The figure shows the schematic diagram of the interference source detection system, which mainly includes:

[0132] The target site 701 is used to continuously monitor the atmospheric waveguide reference signal; and send the monitored atmospheric waveguide reference signal and the identifier of the target site to the network management server;

[0133] The network management server 702 is used to obtain the atmospheric duct reference signal monitored by the target site and the identifier of the target site; and determine whether the target site is an interference source according to the atmospheric duct reference signal and the identifier of the target site.

[0134] In some embodiments, the system further includes a disturbed site 703, which is used to start a timer; if the timer has not timed out, continue to send the atmospheric waveguide reference signal; if the timer has timed out, stop sending the atmospheric waveguide reference signal.

[0137] In addition, it should be noted that the target site and the disturbed site may be the same site or different sites, that is, one site may operate as a target site and a disturbed site at the same time.
