[0028] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0029] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0030] In order to better understand the embodiments of the present application, the technical terms involved in the embodiments of the present application are explained as follows:

[0031] RSSI (Received Signal Strength Indicator): This indicator measures the strength of the received signal. It is implemented after the reverse channel baseband receive filter and is often used to assess interference noise during field evaluations. Measuring the average RSSI value when the base station is unloaded is the primary method for determining interference. For new deployments with few users, the RSSI level under no-load conditions is typically less than -110dBm. When multiple services are in operation, the average RSSI value typically does not exceed -95dBm.

[0032] Currently, different 5G application scenarios require flexible frame structures, which results in cross-time slots in duplex scenarios where different frame structures coexist, causing strong uplink interference to adjacent base stations. Figure 1 Taking the flexible frame structure configuration scenario as an example, there will be cross interference between downlink frames and uplink frames on SLOT2, SLOT3, and SLOT7. Figure 1 In the expression "D" (downlink frame), "U" (uplink frame), and "S" (special subframe), this interference is unidirectional: only the DL symbols of the aggressor's downlink timeslot or the DL symbols of the special timeslot cause cross-interference in the victim's uplink timeslot; there is no interference from the victim to the aggressor. To prevent this interference from impacting services, base stations can employ various techniques, such as power suppression, timeslot shutdown, and frequency-domain coordinated scheduling.

[0033] To ensure user experience in areas with heterogeneous frame structures, it is crucial to reduce cross-slot interference. For example, for services with high uplink capacity requirements, such as cameras, 1D3U is often deployed to increase the uplink subframe ratio due to the high proportion of downlink subframes in the 7:3 frame structure. However, the resulting heterogeneous cross-slot interference can severely impact the quality of camera video feeds.

[0034] In order to solve the above problems, relevant solutions are provided in the embodiments of the present application, which are described in detail below.

[0035] According to an embodiment of the present application, a method embodiment of a method for reducing communication interference is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0036] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Figure 2 FIG1 shows a hardware structure block diagram of a computer terminal for implementing a method for reducing communication interference. Figure 2 As shown, the computer terminal 20 may include one or more (illustrated as 202a, 202b, ..., 202n in the figure) processors 202 (the processor 202 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA), a memory 204 for storing data, and a transmission device 206 for communication functions. In addition, it may also include: a display, an input / output interface (I / O interface), a universal serial bus (USB) port (which may be included as one of the ports of the BUS bus), a network interface, a power supply and / or a camera. It will be understood by those skilled in the art that Figure 2 The structure shown is only for illustration and does not limit the structure of the above electronic device. Figure 2 More or fewer components than shown, or with Figure 2 Different configurations shown.

[0037] It should be noted that the one or more processors 202 and / or other data processing circuits described above may generally be referred to herein as "data processing circuitry." The data processing circuitry may be embodied in whole or in part as software, hardware, firmware, or any other combination thereof. Furthermore, the data processing circuitry may be a single, independent processing module, or may be incorporated in whole or in part into any of the other components of the computer terminal 20. As described in the embodiments of the present application, the data processing circuitry serves as a processor control (e.g., selection of a variable resistor terminal path connected to an interface).

[0038] The memory 204 can be used to store software programs and modules of application software, such as the program instructions / data storage device corresponding to the communication interference reduction method in the embodiments of the present application. The processor 202 executes the software programs and modules stored in the memory 204 to perform various functional applications and data processing, thereby implementing the above-mentioned communication interference reduction method. The memory 204 may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 204 may further include memory remotely located relative to the processor 202, and these remote memories may be connected to the computer terminal 20 via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0039] Transmission device 206 is configured to receive or transmit data via a network. A specific example of the aforementioned network may include a wireless network provided by the communications provider of computer terminal 20. In one embodiment, transmission device 206 includes a network interface controller (NIC), which can be connected to other network devices via a base station to enable communication with the Internet. In another embodiment, transmission device 206 may be a radio frequency (RF) module configured to communicate with the Internet wirelessly.

[0040] The display may be, for example, a touch screen liquid crystal display (LCD) that enables a user to interact with a user interface of the computer terminal 20 .

[0041] In the above operating environment, the embodiment of the present application provides a method for reducing communication interference, such as Figure 3 As shown, the method includes the following steps:

[0042] Step S302: Obtain a neighboring cell list uploaded by the first base station, wherein the neighboring cell list includes a second cell that causes communication interference to a first cell covered by the first base station;

[0043] In the technical solution provided in step S302, before obtaining the neighboring cell list uploaded by the first base station, the method also includes: the first cell detects unknown neighboring cells within a preset time period, wherein the unknown neighboring cells are neighboring cells of the first cell that have not been added to the neighboring cell list; when the number of times the unknown neighboring cell is detected reaches a preset number, the network cell global identification information of the unknown neighboring cell is added to the neighboring cell list.

[0044] As an optional implementation, the network management platform can issue an ANR (Automatic Neighbor Relation) NR (New Radio) neighbor self-discovery function policy to the gNodeB1 cell group to enable the neighbor ANR function based on air interface measurements. The cell in the gNodeB1 cell group is the first cell mentioned above. The ANR NR neighbor self-discovery function policy refers to the automatic neighbor relation function implemented in the new radio network.

[0045] In some embodiments of the present application, the first cell and the second cell are as follows: Figure 4 As shown in the figure. The gNodeB1 group is the first cell group, and the gNodeB2 cell is the second cell group. Figure 4 The frame structures 1D3U and 7:3 are only examples, and do not mean that the frame structure of the first cell must be 1D3U, nor does it mean that the frame structure of the second cell must be 7:3.

[0046] After that, the first base station will ask the terminal equipment connected to the first cell to report the MeasurementReport within a preset time period, and accumulate the number of times each unknown neighboring cell is discovered based on the measurement report. Specifically, each time an unknown neighboring cell is detected, the number of times the unknown neighboring cell is discovered is increased by 1. And a discovery number threshold F can be set. When the number of times an unknown neighboring cell is discovered reaches F, the NCGI (Network Cell Global Identifier) information of the unknown neighboring cell is added to the neighboring cell list.

[0047] Optional, such as Figure 5 As shown, the first base station will collect the detected neighboring cells into a temporary table and mark the status of each neighboring cell as known or unknown. Figure 5 The neighboring cell corresponding to number 3 in the upper part is still in an unknown state because the number of detections N3 has not reached F. Figure 5 As shown in the lower part, when the number of detections reaches F, its status will be changed to known. In addition, for neighboring cells with unknown status, when their status becomes known, the NCGI information of the cell and the corresponding base station number and cell number will be added to the corresponding unit in the table. Afterwards, the first base station will summarize the neighboring cells with known status into a neighboring cell list and send it to the network management platform UIME (Unified Management Entify). As an optional implementation method, all neighboring cells (including neighboring cells with known status and neighboring cells with unknown status) can also be added to the neighboring cell list and sent to the UME. Then, as shown in the table below, the UME determines the punching template adapted for each neighboring cell with known status.

[0048]

[0049]

[0050] The PCI in the above table is a physical cell identifier (Physical Cell Identify).

[0051] Step S304, determining the downlink physical resource block utilization rate of the second cell;

[0052] As an optional implementation manner, the UME may count downlink PRB (Physical Resource Block) utilization of each second cell.

[0053] Step S306: Determine the target puncturing template adapted for the second cell based on the downlink physical resource block utilization of the second cell, and send a puncturing configuration instruction generated based on the target puncturing template to the second cell, wherein the puncturing configuration instruction is used to instruct the second cell not to transmit part of the data in the downlink frame based on the target puncturing template.

[0054] In the technical solution provided in step S306, the step of determining the target perforation template adapted for the second cell based on the downlink physical resource block utilization of the second cell includes: when the downlink physical resource block utilization is less than the first preset threshold, determining the first perforation template as the target perforation template; when the downlink physical resource utilization is not less than the first preset threshold and less than the second preset threshold, determining the second perforation template as the target perforation template; when the downlink physical resource utilization is not less than the second preset threshold, determining the third perforation template as the target perforation template, wherein the proportion of downlink frame prohibited transmission data corresponding to the first perforation template is less than the proportion of downlink frame prohibited transmission data corresponding to the second perforation template, and the proportion of downlink frame prohibited transmission data corresponding to the second perforation template is less than the proportion of downlink frame prohibited transmission data corresponding to the third perforation template.

[0055] It should be noted that puncturing refers to reserving or disabling a portion of resources within a predetermined time or frequency resource in order to reduce or avoid interference. Specifically, puncturing in 5G networks usually refers to the intentional non-use (i.e., "puncturing") of certain downlink time slots or symbols by a base station according to a specific strategy during network scheduling, to prevent these time slots or symbols from conflicting with the uplink activities of neighboring base stations, thereby reducing cross-slot interference.

[0056] In some embodiments of the present application, after determining the target puncturing template adapted to the second cell according to the downlink physical resource block utilization rate of the second cell, the method further includes: determining a target beam template corresponding to the target puncturing template; and sending a beam configuration instruction generated according to the target beam template to the second cell, where the beam configuration instruction is used to indicate the activation state of the beam corresponding to the second cell.

[0057] In some embodiments of the present application, as Figure 6 shown, if the downlink PRB utilization rate DL-PRBx of a certain cell < DL_L, then the puncturing template 0 (the first puncturing template S1) is selected as the target puncturing template of the cell. If DL_L ≤ DL-PRBx < DL_H, then the puncturing template 1 (the second puncturing template S2) is selected as the target puncturing template of the cell. If DL_H ≤ DL-PRBx, then the puncturing template 2 (the third puncturing template S3) is selected as the target puncturing template of the cell. If the second cell is configured with the corresponding puncturing template, then all of its corresponding SSB (Synchronization Signal / Physical Broadcast Channel) beam templates are selected as template 1, otherwise template 0 is adopted.

[0058] As an optional implementation manner, the identifier in the target puncturing template includes at least one of the following: a non-puncturing identifier, a full-puncturing identifier, and a partial-puncturing identifier, where the non-puncturing identifier is used to indicate that the downlink data transmission in the corresponding time slot is not prohibited, the full-puncturing identifier is used to indicate that all downlink data transmissions in the corresponding time slot are prohibited, the partial-puncturing identifier is used to indicate that some downlink data transmissions in the time slot are prohibited, and the position information of the prohibited downlink data is indicated.

[0059] As an optional implementation manner, the beam template includes an activation identifier and a deactivation identifier, where the activation identifier is used to indicate that the beam state corresponding to the activation identifier is an active state; the deactivation identifier is used to indicate that the beam state corresponding to the deactivation identifier is an inactive state.

[0060] Optionally, as Figure 6 shown, the non-puncturing identifier in the puncturing template is 0, and the full-puncturing representation is 14, indicating that all 14 downlink symbols in the time slot stop transmission. S-UL indicates that the downlink symbols at the position of S-UL in the special time slot stop transmission. The downlink symbols in the special time slot S are divided into S-DL, S-GAP, and S-UL. The 0 in the beam template is the deactivation identifier, and the 1 is the activation identifier.

[0061] In some embodiments of the present application, in the puncturing template, 0 means that within a specified time unit (usually a time resource block, such as a symbol or subframe), the base station will not actively reduce or cancel its downlink resource allocation. In other words, the position of "0" means that the base station can send downlink data or control information normally as originally planned, and no resources are punctured (i.e., reserved or disabled). 14 represents the number of downlink symbols in a complete time slot, that is, in a TDD (Time Division Duplexing) system, for a time slot containing 14 symbols, if a position is marked as "14", it means that in this time slot, the base station will stop all downlink transmission activities and reserve the resources of the time slot to avoid interference with the uplink transmission of the adjacent cell. Such puncturing is to separate the uplink and downlink activities of different cells in time, thereby reducing the impact of cross-slot interference.

[0062] In the beam template, 1 usually means that the beam in that direction or on the corresponding antenna is activated. This means that the base station will use a specific antenna or antenna combination to transmit or receive signals with a specific directionality and power. When optimizing network performance, for example, in scenarios where cross-timeslot interference is reduced, the activated beam can be directed to areas where service is more needed or signal quality is more fragile to enhance service quality and reduce interference. 0 means that the beam in that direction or on the corresponding antenna is not activated. This may mean that the beam in a certain direction is turned off to avoid causing unnecessary interference to neighboring areas. In particular, in scenarios where cross-timeslot interference needs to be reduced, by turning off unnecessary beams, the base station's signal transmission in a specific direction can be reduced, thereby reducing interference to the uplink time slots of neighboring base stations.

[0063] For example, consider a base station consisting of multiple antennas. In the beam template, the sequence of 1s and 0s indicates the activation status of the antenna or antenna combination. For example, "1 0 0 0 1 1" can indicate that the first, fifth, and sixth antennas or antenna groups are activated for beamforming, while the other antennas are not activated. This reduces the spread of signals in unwanted directions, thereby reducing interference to neighboring cells.

[0064] In complex network environments, dynamic adjustment and optimization of beam templates can significantly improve network performance, especially in scenarios where multiple cells and users coexist with varying service requirements and interference sources. By precisely controlling the direction and intensity of beams, the network can serve multiple users more efficiently and intelligently, while reducing inter-cell interference, improving spectrum utilization, and enhancing overall network capacity and user experience.

[0065] As an optional implementation manner, multiple optional puncturing templates may be preset according to the frame structure of the first cell and the distribution of actually interfered uplink frames.

[0066] In some embodiments of the present application, after determining the target perforation template adapted for the second cell based on the downlink physical resource block utilization of the second cell, the method further includes: determining the fluctuation of the received signal strength of the first cell, and the fluctuation of the uplink and downlink rates of the second cell; when it is determined that the received signal strength of the first cell fluctuates abnormally based on the fluctuation of the received signal strength, or when it is determined that the uplink and downlink rates of the second cell fluctuate abnormally based on the fluctuation of the uplink and downlink rates, executing a performance self-check process.

[0067] In some embodiments of the present application, the standard for determining abnormal RSSI fluctuations may be that the RSSI is lower than the threshold Tr or that the daily fluctuation ratio is greater than or equal to Dr. The standard for determining abnormal downlink PRB utilization fluctuations may be that the daily fluctuation ratio is greater than or equal to Dp, or that the fluctuation ratio determined by the uplink or downlink user rate fluctuation detection is greater than or equal to Dul or Ddl. Dr, Dp, Dul, and Ddl are all preset thresholds.

[0068] In some embodiments of the present application, it is assumed that the application scenario is a 5G N78 TDD scenario, in which gNodeB1 is a 1D3U area cell group and gNodeB2 is a 7:3 cell group. In terms of frequency implementation, the gNodeB1 frequency and the gNodeB2 frequency are set to be staggered. Here, the center frequency number of the gNodeB1 cell is 636664, the SSB center frequency is 3509.76 MHz, and the center frequency number of the gNodeB2 cell is 630000, and the SSB center frequency is 3408.96 MHz. The neighboring cells of the gNodeB1 cell are incorporated into the gNodeB2 cell through air interface measurement, that is, the gNodeB1 cell is integrated into the network management and optimization strategy of the gNodeB2 cell using the air interface measurement mechanism.

[0069] Optionally, gNodeB1 uses its UE (user equipment) or other built-in measurement capabilities to collect wireless signal information from the surrounding environment, including signal strength and quality from other base stations, as well as possible co-channel and adjacent channel interference. This measurement information includes key parameters such as the PCI (Physical Cell Identity) and NCGI (Network Cell Global Identity) of neighboring cells, helping to identify other cells in the surrounding network environment.

[0070] Once gNodeB1 discovers a potential neighboring cell through air interface measurements, it reports this information to the network management layer (e.g., the UME unified management system). The network management layer then analyzes this information and formulates appropriate policies, such as timeslot puncturing configuration and SSB beam adjustment, to reduce inter-cell interference, particularly addressing cross-slot interference. These policies are ultimately applied to the configuration of gNodeB2's cell. By adjusting gNodeB2's radio resource allocation, gNodeB2 avoids or mitigates interference with gNodeB1, thereby optimizing overall network performance.

[0071] In short, using information from over-the-air measurements, the network intelligently adjusts gNodeB2's settings to reduce potential interference to gNodeB1 and its users. This mechanism reflects the self-organizing and self-optimizing nature of modern wireless communication networks, helping to improve network efficiency and user experience.

[0072] Afterwards Figure 7 As shown, the following interaction process can be used to reduce the interference of the gNodeB2 cell to the gNodeB1 cell:

[0073] The first step is to issue the ANR NR neighbor cell self-discovery function policy: The network management sends the ANR NR neighbor cell self-discovery function policy to the gNodeB1 cell group and starts the neighbor cell ANR function based on air interface measurement;

[0074] Step 2: Reporting the Measurement Report: The terminal connected to the gNodeB1 cell group reports the Measurement Report to the base station gNodeB1 corresponding to the gNodeB1 cell group;

[0075] In the third step, gNodeB1 identifies and detects unknown NR neighboring cells and accumulates the number of neighboring cell discoveries. After receiving the Measurement Report, gNodeB1 increments the number of discovered neighboring cells by 1. The detected neighboring cell list includes the neighboring cell's PCI, addition time, status, number of discovered cells, base station ID, and cell ID. The number threshold F is configurable by the operator, for example, 5 times.

[0076] Step 4: Measure the NCGI information of the unknown neighboring cell of NR: When the number of discovery times Nx of an unknown neighboring cell PCIx satisfies Nx=F, the home gNodeB1 cell is triggered to send the NCGI measurement information;

[0077] Step 5: The terminal reports the NCGI information of the unknown NR neighbor cell: After the UE receives the NCGI measurement message sent in step 4, the terminal reports the NCGI information of the unknown NR neighbor cell to the home gNodeB1 cell, and the base station gNodeB1 summarizes it;

[0078] Step 6: Figure 8 As shown, gNodeB1 sets the state of the unknown neighbor cell whose detection times reaches F to the known state, and adds its NCGI information to the neighbor cell list.

[0079] As an optional implementation, during the detection process, assume that after gNodeB1 receives five MRs (Measurement Report Count) related to gNB2c / PCI=102, it adds gNB2c to the gNB2 cell group and triggers the gNB1 cell group to send NCGI measurement information. After the terminal reports the NCGI related to gNB2c / PCI=102, it detects that the neighbor list is updated to record the base station ID and cell ID of the cell gNB2c / PCI=102. Subsequently, after the number of triggers related to gNB2d / PCI=11 reaches five, it triggers the gNB1 cell group to send NCGI measurement information. The terminal reports the NCGI related to gNB2d / PCI=11 and detects that the neighbor list is updated to record the base station ID and cell ID of the cell gNB2d / PCI=11.

[0080] It should be noted that in wireless communication networks, the MR count (Measurement Report Count) refers to the number of times a user equipment (UE) reports a measurement report (MR) to the serving cell (usually the base station it is currently connected to). The measurement report contains key information such as the signal strength and quality of the neighboring cells detected by the UE. This data is very important for network optimization, handover decisions, interference management, etc.

[0081] The UE measures neighboring cell signals periodically or based on specific events (such as when signal quality drops below a certain threshold). It then aggregates these measurement results into measurement reports and reports them to the base station. MR statistics help the network understand the frequency and intensity of interactions between the UE and its neighbors. This allows the network to identify neighboring cells that are causing significant interference to users in the current serving cell or that could potentially become better serving cells. This has a direct impact on dynamically adjusting network configuration, optimizing handover strategies, and mitigating interference.

[0082] Step 7: Send the neighbor list to UME.

[0083] In step 8, the UME determines the puncturing template and beam template that match each cell based on the downlink PRB utilization of each cell in the neighboring cell list;

[0084] Step 9: Send the timeslot puncturing configuration to each cell based on the puncturing template and beam template;

[0085] Step 10: Start the performance monitoring process;

[0086] Step 11: After detecting abnormal performance indicators, start the performance self-check process.

[0087] Optionally, performance indicators include RSSI and downlink PRB utilization. The criteria for determining abnormal RSSI fluctuations can be a value below the threshold Tr or a daily fluctuation ratio greater than or equal to Dr. The criteria for determining abnormal downlink PRB utilization fluctuations can be a daily fluctuation ratio greater than or equal to Dp, or a fluctuation ratio greater than or equal to Dul or Ddl for uplink or downlink user rate fluctuation detection. Dr, Dp, Dul, and Ddl are all preset thresholds. Each threshold can be set by the operator, for example, Tr = -95, Dr = 10%, Dp = 10%, Dul = 10%, and Ddl = 10%. Thus, the criteria for determining abnormal RSSI fluctuations are a value below the threshold -95dBm or a daily fluctuation ratio greater than or equal to 10%, and the criteria for determining abnormal downlink PRB utilization fluctuations are a daily fluctuation ratio greater than or equal to 10%. The fluctuation ratio for uplink or downlink user rate fluctuation detection is greater than or equal to 10%.
