Taking base station 1 and base station 2 as an example, it is assumed that the cells of base station 1 and base station 2 are adjacent cells and belong to the same frequency base stations with different frame structures. In addition, base station 1 mainly provides high-speed download services, so the data volume of the downlink signal of base station 1 is large, and base station 2 mainly provides large-capacity upload services, so the data volume of the uplink signal of base station 2 is large. In the above situation, there will be a CLI (Cross Link Interference) phenomenon between base stations 1 and 2, in which base stations 1 and 2 interfere with each other, especially the downlink signal sent by base station 1 has a greater impact on the uplink signal sent by base station 2.

[0084] In the embodiments of the present invention, the term "and / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent three situations: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0085] In the embodiments of the present invention, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0086] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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 of the present invention, all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0087] In order to perform CLI detection, embodiments of the present invention provide a cross-link interference detection method, base station, device, system and storage medium.

[0088] In one embodiment of the present invention, a cross-link interference detection method is provided, which is applied to a base station. The method includes:

[0089] Obtaining a signal to be transmitted;

[0090] Determine target characterization information corresponding to the target beam used to transmit the signal to be transmitted, wherein the target characterization information indicates an identifier of the target beam and an identifier of a cell to which the target beam belongs;

[0091] The target characterization information is inserted at a position in the above-mentioned signal to be transmitted where the frequency domain interval is the preset frequency domain interval corresponding to the above-mentioned target beam and the time domain interval is the target time domain interval, wherein the above-mentioned target time domain interval is determined based on the following information: the cell identifier of the target cell to which the above-mentioned target beam belongs, the total number of information of different characterization information, the total number of cells in the working scene where the above-mentioned base station is located, the total number of frequency domain intervals of the frequency domain interval corresponding to each time domain interval, the maximum total number of beams configured for the cell in the above-mentioned working scene, and the beam identifier of the above-mentioned target beam;

[0092] The target beam is used to transmit the signal to be transmitted after the target characterization information is inserted, so that other base stations can perform cross-link interference CLI detection based on the received signal.

[0093] From the above, it can be seen that the base station adds the target characterization information corresponding to the target beam for transmitting the signal to be transmitted at the target time domain interval and the preset frequency domain interval of the signal to be transmitted, and the target characterization information can represent the identifier of the target beam and the identifier of the cell to which the target beam belongs. Therefore, after the above-mentioned base station transmits the above-mentioned signal to be transmitted, the base station that receives the signal can determine the identifier of the beam represented by the target characterization information and the identifier of the cell to which the beam belongs based on the target characterization information carried in the signal, thereby determining the target beam for transmitting the signal and the target cell to which the target beam belongs, determining whether the target beam is an interference beam, whether the target cell is an interference cell, and obtaining the CLI detection result.

[0094] In another embodiment of the present invention, a cross-link interference detection method is provided, which is applied to a base station. The method includes:

[0095] In the case of receiving a signal transmitted by another base station, searching for characterization information contained in the signal, wherein the characterization information indicates a first identifier of a target beam and a second identifier of a target cell to which the target beam belongs, and the target beam is: a beam used by the other base station to transmit the signal;

[0096] Determining the interference intensity of the target beam according to the signal information of the signal;

[0097] When the interference intensity is greater than the preset intensity, the first identifier and the second identifier are obtained according to the found characterization information to obtain the CLI detection result.

[0098] As can be seen from the above, after receiving the signal, the base station can determine the first identifier of the beam represented by the target characterization information and the second identifier of the cell to which the beam belongs based on the target characterization information carried in the signal, thereby determining the target beam used to transmit the signal and the target cell to which the target beam belongs. Then, the interference strength of the target beam is determined based on the signal information of the signal, thereby determining whether the target beam is an interference beam and whether the target cell is an interference cell, and obtaining the CLI detection result.

[0099] The technical solution provided by the embodiment of the present invention can be applicable to a variety of systems, especially 5G systems. For example, the applicable system can be a global system of mobile communication (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) general packet radio service (GPRS) system, a long term evolution (LTE) system, a LTE frequency division duplex (FDD) system, a LTE time division duplex (TDD) system, an advanced long term evolution (LTE-A) system, a universal mobile telecommunication system (UMTS), a world-wide interoperability for microwave access (WiMAX) system, a 5G new radio (NR) system, etc. These various systems include terminals and network equipment. The system may also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), etc.

[0100] The terminal involved in the embodiment of the present invention may be a device that provides voice and / or data connectivity to a user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem. In different systems, the name of the terminal may also be different. For example, in a 5G system, the terminal may be called a user equipment (UE). A wireless terminal can communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal may be a mobile terminal, such as a mobile phone (or a "cellular" phone) and a computer with a mobile terminal. For example, it may be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges language and / or data with a radio access network. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs) and other devices. A wireless terminal may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, and a user device, but is not limited thereto in the embodiments of the present application.

[0101] In addition, in an embodiment of the present invention, the base station and the terminal may each use one or more antennas for multiple input multiple output (MIMO) transmission, and the MIMO transmission may be single user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO). Depending on the form and number of antenna combinations, MIMO transmission may be 2D-MIMO, 3D-MIMO, FD-MIMO or massive-MIMO, or may be diversity transmission, precoded transmission or beamforming transmission, etc.

[0102] See also Figure 1, is a schematic diagram of an application scenario of cross-link interference detection provided by an embodiment of the present invention.

[0103] It can be seen from the figure that base station 1 mainly provides high-speed download services for terminal 1, and base station 2 mainly provides large-capacity upload services for terminal 2. The dotted box surrounding base station 1 represents the coverage of base station 1, and the dotted box surrounding base station 2 represents the coverage of base station 2. There is an overlapping part between the coverage of base station 1 and the coverage of base station 2. When base station 1 and base station 2 are co-frequency base stations with different frame structures, there will be a CLI phenomenon of mutual interference between base station 1 and base station 2, especially the downlink signal sent by base station 1 has a greater impact on the uplink signal sent by base station 2.

[0104] Specifically, base station 1 may be a base station using a 2.5 double frame structure, and base station 2 may be a base station using a 1D3U frame structure. Of course, the frame structures used by base station 1 and base station 2 may also be other different frame structures.

[0105] In addition, the above Figure 1 This is only an example of an application scenario for cross-link interference detection. In actual application scenarios, there may be more than two base stations with overlapping or adjacent coverage areas, and base stations with the same frequency but different frame structures will affect each other.

[0106] See also Figure 2A , which is a flow chart of the first cross-link interference detection method provided in an embodiment of the present invention, and is applied to a base station. Among them, the above-mentioned base station is a base station that may cause CLI to other base stations, so the above-mentioned base station can be called an interference source base station. Since each base station may cause interference to other base stations, the above-mentioned base station can be any base station in the above-mentioned application scenario. However, since the downlink signal has a greater impact on the CLI of the uplink signal, the downlink base station that mainly transmits the downlink signal needs other base stations to detect the CLI impact caused by itself, so the above-mentioned base station can also be a downlink base station.

[0107] The above method includes the following steps S201-S204.

[0108] S201: Obtain a signal to be transmitted.

[0109] S202: Determine target characterization information corresponding to the target beam used to transmit the signal to be transmitted.

[0110] The target characterization information indicates the identifier of the target beam and the identifier of the cell to which the target beam belongs.

[0111] Specifically, the above-mentioned beam identifier and the cell identifier can be expressed in the form of numbers or characters, and in particular, the above-mentioned beam identifier and the cell identifier can be expressed in the form of natural numbers. In the working scenario of the above-mentioned base station, the identifiers of the beams configured in each cell of each base station are different, and the identifiers of each cell are also different.

[0112] In addition, the above characterization information may be a binary sequence. A certain amount of characterization information may be preset, and a correspondence between different beams and the preset characterization information may be set. The above correspondence may be stored in the form of a relationship table, and the target characterization information corresponding to the target beam may be determined by searching the above relationship table.

[0113] Among them, the corresponding characterization information can be set for each beam configured for each cell of each base station in the working scene where the above base station is located. It is also possible to set the corresponding characterization information for each cell in units of cells, and then each beam configured in the cell corresponds to the same characterization information. Presetting the characterization information corresponding to the beam can facilitate the base station receiving the signal to distinguish the beam that sends the signal according to different characterization information. Therefore, the more beams there are in the above working scene, the more the number of the above preset characterization information can be.

[0114] Furthermore, the above-mentioned characterization information may be RIM-RS (Remote Interference Management Reference Signal), which is a signal used for remote base station interference detection. The embodiment of the present invention applies it to the application scenario of CLI detection between base stations at a relatively close distance, and can also realize CLI detection between base stations at a relatively close distance. The above-mentioned step S202 can be realized by the following step A.

[0115] Step A: Determine the RIM-RS corresponding to the target beam used to transmit the signal to be transmitted as the target RIM-RS.

[0116] Specifically, the corresponding relationship between each beam and the value of RIM-RS can be preset to determine the RIM-RS corresponding to the target beam. RIM-RS is represented by a sequence composed of binary numbers, so different beams correspond to different sequences.

[0117] S203: Insert the target characterization information at a position in the signal to be transmitted where the frequency domain interval is the preset frequency domain interval corresponding to the target beam and the time domain interval is the target time domain interval.

[0118] Among them, the above-mentioned target time domain interval is determined based on the following information: the cell identifier of the target cell to which the above-mentioned target beam belongs, the total number of information representing different information, the total number of cells in the working scenario where the above-mentioned base station is located, the total number of frequency domain intervals of the frequency domain interval corresponding to each time domain interval, the maximum total number of beams configured for the cell in the above-mentioned working scenario, and the beam identifier of the above-mentioned target beam.

[0119] Specifically, the frequency band in which the above-mentioned base station works can be divided into different frequency domain intervals, and a preset frequency domain interval corresponding to the beam can be allocated to each beam. The corresponding frequency domain interval can be set for each beam configured for each cell of each base station in the working scene where the above-mentioned base station is located. It is also possible to set the corresponding frequency domain interval for each cell in units of cells, so that each beam configured in the cell corresponds to the same frequency domain interval.

[0120] In one embodiment of the present invention, different beams are distinguished by three dimensions: characterization information, frequency domain interval, and time domain interval. Therefore, different characterization information, frequency domain interval, and time domain interval combinations can be set for different beams in the working scenario where the above-mentioned base station is located.

[0121] See also Figure 2B , which is a schematic diagram of a time domain interval and a frequency domain interval provided in an embodiment of the present invention.

[0122] As shown in the figure, the horizontal direction represents the time domain, and the vertical direction represents the frequency domain. Different grids in the horizontal direction correspond to different time domain intervals 1-3, and different grids in the vertical direction correspond to different frequency domain intervals 1-3. Each grid shown in the figure corresponds to a different time domain interval and / or frequency domain interval. For example, grid 1 corresponds to time domain interval 1 and frequency domain interval 1, grid 2 corresponds to time domain interval 2 and frequency domain interval 1, and so on.

[0123] Each grid can correspond to one or more beams. When a grid corresponds to multiple beams, the frequency domain intervals and time domain intervals corresponding to the multiple beams are the same, but the corresponding characterization information is different, so different beams can be distinguished based on the characterization information. The frequency domain intervals and / or time domain intervals corresponding to beams corresponding to different grids are different in themselves, and different beams can be distinguished based on the frequency domain intervals and / or time domain intervals.

[0124] Specifically, each base station in the above working scenario needs to execute the above Figure 2A In the embodiment shown, it is necessary to add characterization information to the transmitted signal, and different characterization information, frequency domain intervals and time domain interval combinations need to be set for all beams of the cells of all base stations. The total number of cells is the total number of cells of all base stations in the above working scenario.

[0125] However, if only the downlink base station included in the above working scenario executes the above Figure 2AThe solution provided by the illustrated embodiment can configure different characterization information, frequency domain interval and time domain interval combinations for each beam of the cell of the downlink base station. The total number of cells is the total number of cells of the downlink base station included in the above working scenario.

[0126] The time domain interval corresponding to each beam may be a preset fixed interval, and the time domain interval corresponding to each beam may be set by the above-mentioned base station or other electronic equipment based on preset rules, or may be set manually. The time domain interval corresponding to each beam may also be calculated in real time by the above-mentioned base station based on preset rules.

[0127] Specifically, the first maximum number of all beams in each cell in the working scenario can be determined based on the total number of cells and the maximum number of beams. Then, at most the first maximum number of combinations of three dimensions of characterization information, frequency domain intervals, and time domain intervals need to be configured to set a corresponding, unique combination of characterization information, frequency domain intervals, and time domain intervals for each beam. The second maximum number of different combinations that can be formed based on the two dimensions of characterization information and frequency domain intervals can be determined based on the above-mentioned total number of information and the total number of frequency domain intervals. Then, based on the first maximum number and the second maximum number, it can be determined how many different time domain intervals need to be configured to obtain the above-mentioned first maximum number of different combinations of characterization information, frequency domain intervals, and time domain intervals based on the characterization information and frequency domain intervals that have been determined. After determining the number of required time domain intervals, the corresponding frequency domain interval, time domain interval, and characterization information combination can be set for the beam based on the beam identifier of the beam, and each beam has a different combination.

[0128] In addition, in order to more conveniently set the corresponding frequency domain interval, time domain interval and characterization information combination for each beam, two parameters can be selected from the above three parameters. The above two parameters corresponding to each beam of each cell are the same. On this basis, the corresponding third parameter is set for each beam of the cell.

[0129] For example, the frequency domain interval and the characterization information may be selected, and the frequency domain interval corresponding to each beam of each cell is the same as the characterization information, and then different time domain intervals corresponding to each beam of the same cell are set to distinguish different beams. On this basis, the time domain intervals set for each beam of the same cell may be adjacent to each other in the time domain, thereby making it easier to set the frequency domain interval, time domain interval and characterization information corresponding to each beam, and the correspondence between the beam and the characterization information, the frequency domain interval and the time domain interval is simpler.

[0130] Furthermore, in the case where the characterization information is RIM-RS, the above step S203 can be implemented by the following step B.

[0131] Step B: inserting the target RIM-RS at a position in the signal to be transmitted where the frequency domain interval is the preset frequency domain interval corresponding to the target beam and the time domain interval is the target time domain interval.

[0132] S204: Transmitting the signal to be transmitted into which the target characterization information is inserted through the target beam, so that other base stations perform CLI detection based on the received signal.

[0133] Specifically, when the above-mentioned base station is configured with multiple beams, the base station will send signals for the cells to which the above-mentioned beams belong in sequence through different beams. The base station sends a signal to be transmitted containing target characterization information through the target beam, so that when the base station receiving the above-mentioned signal determines that the target beam has CLI for itself, it can determine which beam has CLI for itself through the target characterization information carried in the signal, and at the same time, it can determine which cell the above-mentioned beam belongs to, thereby completing CLI detection.

[0134] In addition, the duration of the above signal in the time domain may be greater than or equal to the sum of the durations of the time domain intervals corresponding to each beam, so that for each beam, the position of the characterization information corresponding to the beam can be determined in the signal transmitted by the beam.

[0135] See also Figure 3 , which is a schematic diagram of a signal transmitted by a base station provided in an embodiment of the present invention.

[0136] As shown in the figure, the base station sends three signals, which are sent through different beams. The rectangles in the figure represent the characterization signals contained in the signals. As can be seen from the figure, the characterization information contained in the signals sent by different beams is located in different positions in the signals.

[0137] From the above, it can be seen that the base station adds the target characterization information corresponding to the target beam for transmitting the signal to be transmitted at the target time domain interval and the preset frequency domain interval of the signal to be transmitted, and the target characterization information can represent the identifier of the target beam and the identifier of the cell to which the target beam belongs. Therefore, after the above-mentioned base station transmits the above-mentioned signal to be transmitted, the base station that receives the signal can determine the identifier of the beam represented by the target characterization information and the identifier of the cell to which the beam belongs based on the target characterization information carried in the signal, thereby determining the target beam for transmitting the signal and the target cell to which the target beam belongs, determining whether the target beam is an interference beam, whether the target cell is an interference cell, and obtaining the CLI detection result.

[0138] In one embodiment of the present invention, the target time domain interval corresponding to the target beam can be determined through the following steps C-D.

[0139] Step C: Determine the number of interval groups in the time domain interval group according to the total number of cells, the total number of information and the total number of frequency domain intervals.

[0140] Among them, a time domain interval group contains the time domain intervals corresponding to each beam configured in a cell.

[0141] Specifically, by calculating the product of the total number of the above information and the total number of frequency domain intervals, the number of combinations of different combinations of different representation information and frequency domain intervals can be obtained, that is, in the two dimensions of representation information and frequency domain intervals, the number of different cells in the above combination can be distinguished. Then, by calculating the ratio between the total number of cells and the number of combinations, it can be determined how many different time domain interval groups need to be set to distinguish each cell in the three dimensions of representation information, frequency domain interval, and time domain interval group.

[0142] In one embodiment of the present invention, the number of interval groups of the time domain interval group can be calculated according to the following formula:

[0143]

[0144] Among them, the above N t is the number of interval groups mentioned above, and the above N setID is the total number of cells mentioned above, and the above N f is the total number of frequency domain intervals, the above N s is the total number of the above information.

[0145] Step D: Determine the target time domain interval according to the number of interval groups, cell identifier, total number of information, maximum total number, and beam identifier.

[0146] Specifically, each time domain interval group corresponding to each cell can be preset, and the time domain interval corresponding to each beam in the time domain interval group corresponding to the cell to which it belongs can be preset. The time domain interval group corresponding to the target cell is determined according to the cell identifier, and the target time domain interval corresponding to the target beam in the determined time domain interval group can be determined according to the beam identifier. The above beam identifier can be expressed in the form of numbers or characters.

[0147] In one embodiment of the present invention, each time domain interval group includes the above-mentioned maximum total number of time domain intervals, and the time domain intervals included in each time domain interval group are adjacent in time. When each time domain interval group is adjacent in time domain, the above-mentioned target time domain interval can be determined according to the following formula.

[0148]

[0149] Among them, the above i t is the serial number of the above target time domain interval, n setID is the cell identifier, and the N s is the total number of the above information, the above Nt is the number of interval groups mentioned above, R is the maximum total number mentioned above, is the beam identifier mentioned above.

[0150] Specifically, according to The serial number of the time domain interval group to which the above target time domain interval belongs can be calculated. Since each time domain interval group contains R time domain intervals, and each time domain interval group is adjacent in the time domain, the value obtained by multiplying the above serial number by R is: the serial number of the time domain interval at the front end of the time domain interval group to which the target time domain interval belongs among all time domain intervals - 1. On this basis, the beam identifier of the target beam is added to obtain the serial number of the target time domain interval among all time domain intervals as the serial number of the target time domain interval. Different time domain intervals have different serial numbers. The serial number of the target time domain interval can be calculated by the above formula, and the above target time domain interval can be determined by the serial number of the above target time domain interval.

[0151] As can be seen from the above, based on the known total number of cells, total number of information, total number of frequency domain intervals, cell identifiers, maximum total number, and beam identifiers, the target time domain interval corresponding to the above target beam can be directly determined, without the need to perform complex settings for the time domain intervals corresponding to each beam, so that the process of determining the target time domain interval is relatively simple. And because the beam identifiers of different beams are different, the cell identifiers of different cells are also different, so the time domain intervals determined for different beams are different, avoiding conflicts between different beams. Furthermore, if the working scene to which the base station belongs changes, resulting in the cells of each base station or the beams of each cell included in the above working scene may change, or the preset characterization information or the preset frequency domain interval changes, the embodiment of the present invention can obtain a new target time domain interval according to the changed situation, without the need to re-set the time domain interval corresponding to the beam, which also improves the matching degree between the embodiment of the present invention and the actual application situation.

[0152] See also Figure 4 , which is a flow chart of the second cross-link interference detection method provided in an embodiment of the present invention, and is applied to a base station. The above-mentioned base station is a base station that may be interfered with by other base stations, so the above-mentioned base station can be called a disturbed base station. Since each base station may be interfered with by signals transmitted by other base stations, the above-mentioned base station can be any base station in the above-mentioned application scenario. However, since the uplink signal is greatly affected by the CLI of the downlink signal, the uplink base station that mainly transmits the uplink signal needs to perform CLI detection more, and the above-mentioned base station can also be an uplink base station. The above-mentioned method includes the following steps S401-S403.

[0153] S401: When receiving a signal transmitted by another base station, searching for characterization information contained in the signal.

[0154] The characterization information indicates a first identifier of a target beam and a second identifier of a target cell to which the target beam belongs. The target beam is a beam used by the other base station to transmit the signal.

[0155] Specifically, the base station may traverse the signal according to the characteristics of the characterization information, and search for the characterization information included in the signal.

[0156] In addition, the above signal can be other base stations according to the above Figure 1 The embodiment shown is transmitted through a target beam. Then the base station can sequentially search for the characterization information at different time domain intervals in the signal.

[0157] S402: Determine the interference intensity of the target beam according to the signal information of the signal.

[0158] The above signal information may be the power, amplitude, etc. of the signal.

[0159] Specifically, the greater the power of the signal, the greater the interference intensity to the base station. The interference intensity of the target beam may be determined by a method in the prior art, and the embodiment of the present invention does not limit this.

[0160] S403: When the interference intensity is greater than a preset intensity, the first identifier and the second identifier are obtained according to the found characterization information to obtain a CLI detection result.

[0161] Specifically, if the interference intensity is greater than the preset intensity, it means that the target beam has a greater degree of interference with the base station and interference suppression is required. The first identifier and the second identifier represented by the characterization information can be determined based on the found characterization information. The beam represented by the first identifier is the target beam, and the cell represented by the second identifier is the target cell. That is, the base station can determine that the target beam of the target cell has a greater interference with the base station.

[0162] As can be seen from the above, after receiving the signal, the base station can determine the first identifier of the beam represented by the target characterization information and the second identifier of the cell to which the beam belongs based on the target characterization information carried in the signal, thereby determining the target beam used to transmit the signal and the target cell to which the target beam belongs. Then, the interference strength of the target beam is determined based on the signal information of the signal, thereby determining whether the target beam is an interference beam and whether the target cell is an interference cell, and obtaining the CLI detection result.

[0163] See also Figure 5 , is a flow chart of a third cross-link interference detection method provided by an embodiment of the present invention, which is similar to the aforementioned Figure 4 Compared with the above step S403, it can be implemented by the following steps S403A-S403C.

[0164] S403A: When the above-mentioned interference intensity is greater than the preset intensity, the number of interval groups in the time domain interval group is determined according to the total number of cells in the working scene where the above-mentioned base station is located, the total number of information of different characterization information, and the total number of frequency domain intervals of the frequency domain interval corresponding to each time domain interval.

[0165] Among them, a time domain interval group contains the time domain intervals corresponding to each beam configured in a cell.

[0166] Specifically, the number of interval groups of the time domain interval group can be calculated according to the following formula:

[0167]

[0168] Among them, the above N t is the number of interval groups mentioned above, and the above N setID is the total number of cells mentioned above, and the above N f is the total number of frequency domain intervals, the above N s is the total number of the above information.

[0169] Specifically, the above step S403A is similar to the above step C, and will not be described in detail in this embodiment of the present invention.

[0170] S403B: Determine the above-mentioned second identifier based on the information identifier of the characterization information found, the time domain interval identifier of the time domain interval where the above-mentioned characterization information is located in the above-mentioned signal, the frequency domain interval identifier of the frequency domain interval where the above-mentioned characterization information is located in the above-mentioned signal, the number of the above-mentioned interval groups, the total number of the above-mentioned information, and the maximum total number of beams configured for the cell in the above-mentioned working scenario.

[0171] Specifically, when the base station sending the above-mentioned signal determines the target time domain interval corresponding to the target beam according to the second identifier of the target cell in the manner shown in the above-mentioned step D, the above-mentioned base station can adopt the method opposite to the above-mentioned step D to determine the second identifier of the cell to which the target beam belongs according to the target time domain interval where the characterization information is located.

[0172] In one embodiment of the present invention, the second identifier may be determined according to the following formula:

[0173]

[0174] Among them, the above n setID is the second identifier mentioned above, i s The above information identifier, the above N s is the total number of the above information, the above i t is the time domain interval identifier, R is the maximum total number, and N t is the number of interval groups mentioned above, i f is the frequency domain interval identifier mentioned above.

[0175] Specifically, the above formula is obtained by mathematically deducing the formula shown in the above step D embodiment.

[0176] S403C: Determine the first identifier according to the second identifier and the time domain interval identifier to obtain a CLI detection result.

[0177] Specifically, after determining the above-mentioned second identifier, the time domain interval corresponding to each beam of the target cell represented by the second identifier can be determined according to the preset corresponding relationship. The beam whose corresponding time domain interval is the time domain interval where the above-mentioned characterization information is located is the target beam, and the identifier of the beam whose corresponding time domain interval is the time domain interval where the above-mentioned characterization information is located is the above-mentioned first identifier.

[0178] In one embodiment of the present invention, according to the formula shown in the embodiment of step D above, the determined second identifier and the time domain interval identifier are used as known quantities to calculate the above This is the first identification mentioned above.

[0179] As can be seen from the above, after receiving the signal, the above-mentioned base station can directly adopt a method opposite to the method of the base station sending the above-mentioned signal to determine the target time domain interval corresponding to the target beam, and determine the identifier of the target beam corresponding to the characterization signal according to the target time domain interval where the above-mentioned characterization signal is located. The method of determining the identifier of the target beam is relatively simple. And if the working scene to which the base station belongs changes, resulting in the cells of each base station included in the above-mentioned working scene or the beams of each cell may change, or the preset characterization information or the preset frequency domain interval changes, the embodiment of the present invention can determine the first identifier and the second identifier according to the changed situation, thereby improving the degree of matching between the embodiment of the present invention and the actual application situation.

[0180] Corresponding to the aforementioned cross-link interference detection method, the embodiment of the present invention further provides a base station, see Figure 6 , is a schematic diagram of the structure of a first base station provided in an embodiment of the present invention, wherein the base station includes a memory 601, a transceiver 602, and a processor 603:

[0181] The memory 601 is used to store computer programs; the transceiver 602 is used to send and receive data under the control of the processor; the processor 603 is used to read the computer program in the memory and perform the following operations:

[0182] Obtaining a signal to be transmitted;

[0183] Determine target characterization information corresponding to a target beam used to transmit the signal to be transmitted, wherein the target characterization information represents an identifier of the target beam and an identifier of a cell to which the target beam belongs;

[0184] Insert the target characterization information at a position in the signal to be transmitted where the frequency domain interval is a preset frequency domain interval corresponding to the target beam and the time domain interval is a target time domain interval, wherein the target time domain interval is determined based on the following information: a cell identifier of a target cell to which the target beam belongs, a total number of information of different characterization information, a total number of cells in a working scenario where the base station is located, a total number of frequency domain intervals of a frequency domain interval corresponding to each time domain interval, a maximum total number of beams configured for cells in the working scenario, and a beam identifier of the target beam;

[0185] The signal to be transmitted after the target characterization information is inserted is transmitted through the target beam, so that other base stations perform CLI detection based on the received signal.

[0186] Among them, Figure 6 In the embodiment, the bus architecture may include any number of interconnected buses and bridges, specifically one or more processors represented by processor 603 and various circuits of memory represented by memory 601 are linked together. The bus architecture may also link together various other circuits such as peripherals, voltage regulators, and power management circuits, which are well known in the art and are therefore not further described herein. The bus interface provides an interface. The transceiver 602 may be a plurality of components, namely, a transmitter and a receiver, providing a unit for communicating with various other devices on a transmission medium, which transmission medium may include a wireless channel, a wired channel, an optical cable, and other transmission media. The processor 603 is responsible for managing the bus architecture and general processing, and the memory 601 may store data used by the processor 603 when performing operations.

[0187] The processor 603 may be a central processing unit (CPU), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or a complex programmable logic device (CPLD). The processor may also adopt a multi-core architecture.

[0188] From the above, it can be seen that the base station adds the target characterization information corresponding to the target beam for transmitting the signal to be transmitted at the target time domain interval and the preset frequency domain interval of the signal to be transmitted, and the target characterization information can represent the identifier of the target beam and the identifier of the cell to which the target beam belongs. Therefore, after the above-mentioned base station transmits the above-mentioned signal to be transmitted, the base station that receives the signal can determine the identifier of the beam represented by the target characterization information and the identifier of the cell to which the beam belongs based on the target characterization information carried in the signal, thereby determining the target beam for transmitting the signal and the target cell to which the target beam belongs, determining whether the target beam is an interference beam, whether the target cell is an interference cell, and obtaining the CLI detection result.

[0189] In one embodiment of the present invention, the target time domain interval is determined by:

[0191] The target time domain interval is determined according to the number of interval groups, cell identifier, total number of information, maximum total number, and beam identifier.

[0192] As can be seen from the above, based on the known total number of cells, total number of information, total number of frequency domain intervals, cell identifiers, maximum total number, and beam identifiers, the target time domain interval corresponding to the above target beam can be directly determined, without the need to perform complex settings for the time domain intervals corresponding to each beam, so that the process of determining the target time domain interval is relatively simple. And because the beam identifiers of different beams are different, the cell identifiers of different cells are also different, so the time domain intervals determined for different beams are different, avoiding conflicts between different beams. Furthermore, if the working scene to which the base station belongs changes, resulting in the cells of each base station or the beams of each cell included in the above working scene may change, or the preset characterization information or the preset frequency domain interval changes, the embodiment of the present invention can obtain a new target time domain interval according to the changed situation, without the need to re-set the time domain interval corresponding to the beam, which also improves the matching degree between the embodiment of the present invention and the actual application situation.

[0206] Specifically, the above Figure 6 The steps performed by the base station shown are similar to those described above. Figure 2A The embodiments shown are similar, and the embodiments of the present invention will not be described in detail.

[0207] Corresponding to the aforementioned cross-link interference detection method, another embodiment of the present invention further provides a base station, see Figure 7 , is a schematic diagram of the structure of a second base station provided in an embodiment of the present invention, wherein the base station includes a memory 701, a transceiver 702, and a processor 703:

[0212] As can be seen from the above, after receiving the signal, the base station can determine the first identifier of the beam represented by the target characterization information and the second identifier of the cell to which the beam belongs based on the target characterization information carried in the signal, thereby determining the target beam used to transmit the signal and the target cell to which the target beam belongs. Then, the interference strength of the target beam is determined based on the signal information of the signal, thereby determining whether the target beam is an interference beam and whether the target cell is an interference cell, and obtaining the CLI detection result.

[0213] In one embodiment of the present invention, obtaining the first identifier and the second identifier according to the found representation information specifically includes:

[0214] Determine the number of interval groups in the time domain interval group according to the total number of cells in the working scenario where the base station is located, the total number of information of different characterization information, and the total number of frequency domain intervals of the frequency domain interval corresponding to each time domain interval, wherein a time domain interval group includes the time domain intervals corresponding to each beam configured in a cell;

[0216] The first identifier is determined according to the second identifier and the time domain interval identifier.

[0217] As can be seen from the above, after receiving the signal, the above-mentioned base station can directly adopt a method opposite to the method of the base station sending the above-mentioned signal to determine the target time domain interval corresponding to the target beam, and determine the identifier of the target beam corresponding to the characterization signal according to the target time domain interval where the above-mentioned characterization signal is located. The method of determining the identifier of the target beam is relatively simple. And if the working scene to which the base station belongs changes, resulting in the cells of each base station included in the above-mentioned working scene or the beams of each cell may change, or the preset characterization information or the preset frequency domain interval changes, the embodiment of the present invention can determine the first identifier and the second identifier according to the changed situation, thereby improving the degree of matching between the embodiment of the present invention and the actual application situation.

[0218] In one embodiment of the present invention, determining the number of interval groups of the time domain interval group according to the total number of cells in the working scene where the base station is located, the total number of information of different characterization information, and the total number of frequency domain intervals of the frequency domain interval corresponding to each time domain interval specifically includes:

[0219] The number of interval groups in the time domain is calculated according to the following formula:

[0220]

[0221] Among them, the N t is the number of interval groups, and N setID is the total number of cells, the N f is the total number of frequency domain intervals, and the N s is the total number of the information;

[0224] The second identifier is determined according to the following formula:

[0225]

[0227] Corresponding to the above cross-link interference detection method, see Figure 8 , is a structural diagram of a first cross-link interference detection device provided by an embodiment of the present invention, which is applied to a base station, and the device includes:

[0228] The signal acquisition module 801 is used to obtain the signal to be transmitted;

[0229] An information determination module 802 is used to determine target characterization information corresponding to a target beam used to transmit the signal to be transmitted, wherein the target characterization information represents an identifier of the target beam and an identifier of a cell to which the target beam belongs;

[0230] An information insertion module 803 is used to insert the target characterization information at a position in the signal to be transmitted where the frequency domain interval is a preset frequency domain interval corresponding to the target beam and the time domain interval is a target time domain interval, wherein the target time domain interval is determined based on the following information: the cell identifier of the target cell to which the target beam belongs, the total number of information of different characterization information, the total number of cells in the working scene where the base station is located, the total number of frequency domain intervals of the frequency domain interval corresponding to each time domain interval, the maximum total number of beams configured for the cells in the working scene, and the beam identifier of the target beam;

[0231] The signal transmission module 804 is used to transmit the signal to be transmitted after the target characterization information is inserted through the target beam, so that other base stations perform CLI detection based on the received signal.

[0242] See also Fig.11 , is a flow chart of a fourth cross-link interference detection method provided by an embodiment of the present invention. The above method includes the following steps S1101-S1107.

[0243] S1101: The first base station 1001 obtains a signal to be transmitted.

[0244] S1102: The first base station 1001 determines target characterization information corresponding to a target beam used to transmit the signal to be transmitted.

[0245] The target characterization information indicates the identifier of the target beam and the identifier of the cell to which the target beam belongs.
