[0004] Under certain meteorological conditions, electromagnetic waves propagating in the atmospheric boundary layer, especially near the ground, are bent toward the ground by atmospheric refraction. When the curvature exceeds that of the Earth's surface, some of the electromagnetic waves are trapped within a thin layer of atmosphere of a certain thickness, much like electromagnetic waves propagating through a metal waveguide. This phenomenon is known as atmospheric ducting. Atmospheric ducting propagates over long distances, potentially causing long-range co-channel interference to fifth-generation mobile communication technology (5G) New Radio (NR) communication systems.

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 expressly defined in this disclosure.

[0046] 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. If there are multiple sites, different disturbed sites execute the same processing flow.

[0047] The interfering site refers to the site that applies atmospheric waveguide interference and is the real atmospheric waveguide interference source.

[0048] 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 monitoring the atmospheric waveguide reference signal in the same geographical area during the same time period. If there are multiple target sites, different target sites execute the same processing flow.

[0049] 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.

[0050] The application scenario of atmospheric duct interference includes a network management server and multiple sites, all of which can establish a communication connection with the network management server. If at least one of these multiple sites is affected by atmospheric duct interference, how to quickly and accurately locate the interfering site from other sites is the problem addressed by the various methods provided in the embodiments of this disclosure.

[0051] An embodiment of the present disclosure provides an interference source detection method, which can be applied to a network management server.

[0052] FIG1 is a flow chart of the interference source detection method. The method flow for the network management server to detect interference sources mainly includes the following steps:

[0053] Step 101: The network management server obtains an atmospheric duct reference signal monitored by a target site and an identifier of the target site.

[0054] The atmospheric waveguide reference signal is also called a remote interference management reference signal (Remote Interference Management Reference Signal, RimRs), and is usually a RimRs1 signal or an RS-1 signal in related protocols.

[0055] The identifier of the target site may be an identifier (ID) of a next generation base station (gNB), where gNB is a 5G base station.

[0056] In some embodiments, the network management server receives the atmospheric duct reference signal and the identifier of the target site sent by the target site. The network management server may receive the atmospheric duct 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. The interference source detection process for one target site is used as an example for description herein.

[0057] 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.

[0058] 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.

[0059] 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 distance 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 distance characterization value of the detection distance and the sign bit of the detected disturbing site as the parameters for determining the signal transmission distance.

[0060] 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.

[0061] Table 1 shows the output parameters of the 5G atmospheric waveguide characteristic sequence, and Table 2 shows the meaning of the output parameters of the 5G atmospheric waveguide characteristic sequence. It should be noted that the specific values ​​of each parameter in Tables 1 and 2 are examples.

[0062] Table 1

[0063] Table 2

[0064] In some embodiments, the network management server determines whether the target site is an interference source of the atmospheric waveguide 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 waveguide 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 waveguide based on the comparison result.

[0065] In some embodiments, the spatial distance value between the target site and the disturbed site is determined based on the identifier of the target site and the identifier of the disturbed site, including: obtaining the spatial location information of the disturbed site based on the identifier of the disturbed site, and obtaining the spatial location information of the target site based on the identifier of the target site; determining the spatial distance value between the target site and the disturbed site based on 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 based on 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 for determining the signal transmission distance, including:

[0068] When the detection distance representation value TddRimDetectOSNum indicates far, the transmission distance value of the atmospheric waveguide reference signal is determined as: the transmission distance value corresponding to the sum of the 26 symbol bits accumulated based on the symbol bit of the detected interference site, namely SymbolIndex;

[0069] When TddRimDetectOSNum indicates near, the transmission distance value of the atmospheric waveguide reference signal is determined as: the transmission distance value corresponding to the sum of the 6 symbol bits accumulated based on the symbol bit of the detected interfering 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 When TddRimDetectOSNum is set to Near, the RimRs signal is located at the last two Ds of the S slot. When TddRimDetectOSNum is set to Far, the RimRs signal is located at the last two symbols of the second D before the S slot. Assume that TddRimDetectOSNum takes a value of 1 to indicate Far and a value of 0 to indicate Near. The transmission distance 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 waveguide based on the comparison result, including: obtaining the 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 waveguide; if the ratio does not belong to the ratio interval, determining that the target site is not an interference source of the atmospheric waveguide.

[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] Define the confidence interval for the M value [M min ,M max ], judge 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%.

[0078] In the interference source detection method provided by the embodiments of the present disclosure, the target station monitors the atmospheric waveguide reference signal, which may be a real signal sent by the disturbed station after being interfered with by the atmospheric waveguide, or it may be a false detection signal of the target station. The network management server determines whether the target station is an interference source, avoiding the high false detection rate caused by directly treating the target station as an interference source, improving the accuracy of interference source positioning, and because the false detection rate is improved, the efficiency of interference source positioning and interference detection is improved, further avoiding the loss of PDSCH resources caused by false detection, and improving wireless service performance.

[0079] In related technologies, the causes of 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 completely correct detection, which will also cause false detection.

[0080] In the disclosed embodiment, the network management server detects the RimRs1 signal and determines whether it is a false detection signal, which can greatly reduce the false detection rate.

[0081] The present disclosure also provides an interference detection method for a target site, which can be any site that has established a communication connection with a network management server. For example, the target site is a site in the same region as the disturbed site, where there is a possibility of atmospheric duct interference between sites within the region.

[0082] FIG2 is a flow chart of the interference detection method. The flow chart of the interference detection method for the target station mainly includes the following steps:

[0083] Step 201: The target site monitors the atmospheric waveguide reference signal.

[0084] In some embodiments, the target site continuously monitors the atmospheric waveguide reference signal when the atmospheric waveguide function is turned on.

[0085] In 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.

[0086] In some embodiments, after the target site sends the monitored atmospheric duct 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 this disclosure and will not be described in detail.

[0087] 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 identifier 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 identifier of the target site, thereby providing the possibility of reducing the false detection rate.

[0088] An embodiment of the present disclosure further provides an interference notification method, which is applied to a disturbed site, where the disturbed site is a site that detects atmospheric duct interference.

[0089] FIG3a is a flow chart of a method for interference notification. The method for a disturbed station to perform interference notification mainly includes the following steps:

[0090] Step 301: The disturbed station starts a timer.

[0091] 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.

[0092] Step 302: The disturbed station continues to send the atmospheric waveguide reference signal when the timer has not timed out.

[0093] In some embodiments, the disturbed station continuously sending the atmospheric waveguide reference signal means periodically sending the atmospheric waveguide reference signal.

[0094] The timing duration of the timer is greater than the transmission period of the atmospheric waveguide reference signal.

[0095] Step 303: When the timer times out, the disturbed station stops sending the atmospheric waveguide reference signal.

[0096] 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:

[0097] 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;

[0098] Case 2: The area and time period where the atmospheric waveguide interference occurs are statistically obtained. The length of this time period is the second time period. When the current time is about to reach this 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.

[0099] In the interference notification method provided in the embodiments 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:

[0100] 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;

[0101] On the other hand, compared with 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.

[0102] In the Framework-0 method of the 3GPP protocol shown in Figure 3b, the victim station sends a RimRs1 signal after detecting atmospheric waveguide interference --> the interfering station executes a mitigation solution after receiving the RimRs1 signal --> the victim station stops sending the RimRs1 signal if it does not detect atmospheric waveguide interference --> the interfering station stops executing the mitigation solution --> the victim station sends a RimRs1 signal after detecting atmospheric waveguide interference. Compared to the Framework-0 method, in the embodiment of the present disclosure, the victim base station does not repeatedly send and stop sending the RimRs1 signal within the timer's timing, thereby improving efficiency and avoiding resource waste.

[0103] On the other hand, compared to existing solutions, the attacker base station does not need to send feedback signals to stop RimRs1 transmission, which reduces the signal volume. This simplifies the RimRs1 signal stopping process, reduces the resource overhead occupied by signal transmission (such as the time and frequency resources occupied by RS-2 transmission), and shortens the atmospheric duct detection period. In the Framework-1 method implemented by the 3GPP protocol shown in Figure 3c, the interfering station transmits RS-2 to the victim station, and the victim station stops sending RimRs1 after receiving RS-2. In the current Framework-1 implementation based on the 20-bit RimRsSetID, the entire RimRs1 transmission period takes approximately 22 minutes. Due to the limited detection capabilities of the physical layer, if all uplink symbols are detected, the required period is even longer, resulting in poor atmospheric duct detection timeliness and delayed implementation of atmospheric duct mitigation measures. In extreme cases, atmospheric duct mitigation measures are not implemented until the atmospheric duct disappears, which not only wastes PDSCH resources but also fails to achieve true mitigation effect. In the disclosed embodiment, stopping the RimRs1 signal transmission does not require other signal control, but can be controlled by a timer. This reduces the resource overhead occupied by signal transmission and reduces resource waste to a certain extent. In addition, performing the analysis of RimRs1 on the network management server can fully utilize the powerful software and hardware capabilities of the network management server, improve analysis efficiency, and shorten the detection cycle.

[0104] In an exemplary embodiment, as shown in FIG4 , 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, step 402 is executed; otherwise, the process returns to 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 station determines whether the RimRS1 signal is detected. If so, step 404 is executed; otherwise, step 408 is executed.

[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, the RimRS1 signal is discarded and the process returns to step 403. Otherwise, the target station is determined to be an interference source and step 406 is executed.

[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, the process proceeds to step 409; otherwise, the process returns to step 403.

[0113] In step 409 , the disturbed station stops sending the RimRS1 signal and returns to step 401 .

[0114] In an exemplary embodiment, as shown in FIG5 , the second 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 and start a timer T1 for each station in the atmospheric duct generation area, so that the station continuously sends the RimRS1 signal within 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, the process returns to step 503; otherwise, the process proceeds to step 506.

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

[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, the station executes step 509; otherwise, the station returns to step 503.

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

[0125] In an exemplary embodiment, as shown in FIG6a and FIG6b, the atmospheric waveguide function configuration of the disturbing site and the disturbed site is both in an enabled state. The interaction process between the disturbing site, the disturbed site, and the network management server mainly includes:

[0126] Step 601: The interfering site generates atmospheric waveguide remote interference;

[0127] Step 602: The disturbed station performs atmospheric duct interference detection. After detecting atmospheric duct interference, it 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 station is the interference source. Then, the network management server sends a corresponding interference mitigation solution to the interfering station. If the RimRS1 signal is a false detection signal, the process returns to step 603.

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

[0131] The present disclosure also provides an interference source detection system. FIG7 is a schematic diagram of the architecture of the interference source detection system. The system mainly includes:

[0132] The target site 701 is configured to continuously monitor the atmospheric duct reference signal; and transmit the monitored atmospheric duct reference signal and the identifier of the target site to the network management server;

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