[0019] The following describes, with reference to the accompanying drawings, a method for standardizing the configuration parameters of reference signals and a method for mutual testing of network devices, according to embodiments of the present disclosure.

[0020] Figure 1 This is a flowchart illustrating a method for standardizing the parameters of a reference signal according to an embodiment of the present disclosure.

[0021] like Figure 1 As shown, the parameter standardization configuration method for the reference signal may include the following steps: Step 101: Based on the obtained setting parameters of Remote Interference Management Reference Signal (RIM-RS) from different manufacturers and the mutual inspection requirements of network devices between different manufacturers, determine the parameters of RIM-RS to be standardized and the protocol version and protocol constraints used for standardized configuration.

[0022] It should be noted that the parameter standardization configuration method for the reference signal proposed in this disclosure can be applied to the scenario of mutual testing of network devices in atmospheric waveguide scenarios, especially the scenario of mutual testing between network devices from different manufacturers, and this disclosure does not limit it.

[0023] In other words, the parameter standardization configuration method for the reference signal proposed in this disclosure can be used for the parameter standardization configuration of the Remote Interference Management Reference Signal (RIM-RS).

[0024] It should be noted that the entity executing the parameter standardization configuration method for the reference signal proposed in this disclosure can be OAM, CGC, or other dedicated network entities, etc. The specific entity executing the method is not limited, as long as it can complete the parameter standardization configuration of the reference signal and send it to the network device.

[0025] OAM is short for Operations, Administration and Maintenance (OAM).

[0026] CGC stands for Cell Group Coordinator.

[0027] Among these, network equipment can be base stations.

[0028] It should be noted that the RIM-RS settings obtained from different manufacturers, and the specific manufacturers and settings, can be determined according to the actual situation. This disclosure does not impose any restrictions on this.

[0029] The mutual inspection requirements can be defined as the needs of different manufacturers conducting mutual inspections in atmospheric waveguide scenarios. The specific content of these requirements can be set according to actual needs. For example, mutual inspection requirements may include requirements for transmission signal period, resource requirements, and the protocols used, etc., which are not limited in this disclosure.

[0030] The parameter to be standardized can be at least one of the parameters required for the generation, encoding, and modulation of the RIM-RS signal, and can be determined according to actual needs. This disclosure does not limit it.

[0031] For example, in some embodiments, the parameters to be standardized may include at least one of the following: the transmission location of the time-domain resources of RIM-RS, the number of time-division resources, the near-far detection function, the subcarrier spacing, the number of frequency-division resources, the frequency-division resource bandwidth, the starting frequency domain reference point, the starting frequency domain offset, the starting frequency domain resource location, the number of code-division resources and the corresponding orthogonal code groups, the scrambling identifier and the associated scrambling parameters, the identifier of whether the interference avoidance effect is sufficient, the multiplier factor and offset of the scrambling timer, the mapping relationship between the interference type identifier and the time-frequency resources, and sequence parameters, etc., which are not limited in this disclosure.

[0032] The interference type can be the interference type of RIM-RS, such as the type of interference being initiated or the type of interference being received.

[0033] The sequence parameters can be the parameters for generating the base sequence of RIM-RS, and they can be set as needed.

[0034] It should be noted that the protocol version and protocol constraints can be the communication protocol version and constraints, which can be set according to actual needs, and this disclosure does not limit them.

[0035] Step 102: Based on mutual inspection requirements, protocol version and protocol constraints, generate configuration parameters corresponding to the parameters to be standardized.

[0036] Among them, the configuration parameters can be the standardized configuration parameters of RIM-RS used for network device mutual testing.

[0037] In this disclosure, after determining the interoperability requirements of network devices from different vendors, the parameters to be standardized for RIM-RS, the protocol version used, and the protocol constraints, the parameters to be standardized can be configured based on the interoperability requirements, protocol version, and protocol constraints to generate corresponding configuration parameters. This ensures that the generated configuration parameters meet the interoperability requirements of different vendors and comply with the requirements of the protocol version and protocol constraints, thereby achieving standardized and unified configuration of RIM-RS parameters.

[0038] It should be noted that the specific process for generating the configuration parameters corresponding to the parameters to be standardized based on mutual inspection requirements, protocol version, and protocol constraints can be determined according to the actual situation. For example, the time-frequency resource parameters of RIM-RS can be configured based on the protocol version and protocol constraints, and the transmission period and scrambling parameters of RIM-RS can be configured based on mutual inspection requirements, etc. This disclosure does not limit this.

[0039] Step 103: Send the configuration parameters to network devices from different manufacturers.

[0040] Among these, network equipment from different manufacturers can refer to base stations from different manufacturers.

[0041] In this disclosure, after generating the configuration parameters of RIM-RS, the configuration parameters can be sent to network devices from different vendors to achieve standardized and unified configuration of RIM-RS parameters between different vendors, providing a data foundation for mutual testing of network devices from different vendors.

[0042] In this embodiment, firstly, based on the obtained setting parameters of Remote Interference Management Reference Signals (RIM-RS) from different manufacturers and the mutual inspection requirements of network devices from different manufacturers, the parameters to be standardized for RIM-RS, as well as the protocol version and protocol constraints used for standardized configuration, are determined. Then, based on the mutual inspection requirements, protocol version, and protocol constraints, configuration parameters corresponding to the parameters to be standardized are generated. Finally, the configuration parameters are sent to network devices from different manufacturers. Thus, by standardizing and unifying the configuration of RIM-RS parameters through the mutual inspection requirements of network devices from different manufacturers and the protocol version and protocol constraints, it is possible to ensure that network devices from different manufacturers can accurately identify and detect each other's signals, providing conditions for accurate and reliable detection and identification between network devices from different manufacturers.

[0043] Figure 2 This is a flowchart illustrating a method for standardizing the parameters of a reference signal according to an embodiment of the present disclosure.

[0044] like Figure 2 As shown, the parameter standardization configuration method for the reference signal may include the following steps: Step 201: Based on the obtained setting parameters of Remote Interference Management Reference Signal (RIM-RS) from different manufacturers and the mutual inspection requirements of network devices between different manufacturers, determine the parameters of RIM-RS to be standardized and the protocol version and protocol constraints used for standardized configuration.

[0045] The specific implementation of step 201 can be found in the detailed descriptions of other embodiments in this disclosure, and will not be repeated here.

[0046] Step 202: Based on mutual inspection requirements, protocol version and protocol constraints, determine the subcarrier spacing, frequency division resource number, transmission period, and time division resource number, code division resource number and corresponding orthogonal code group, starting frequency domain reference point and starting frequency domain offset, and sequence parameters of RIM-RS.

[0047] Among them, the frequency division resource number can be the number of available frequency division resources of RIM-RS, the time division resource number can be the number of time domain resources available for RIM-RS during the transmission period, and the code division resource number can be used to distinguish RIM-RS signals of different network devices.

[0048] The sequence parameters can be the base sequences used to generate RIM-RS.

[0049] For example, in some embodiments, when determining the subcarrier spacing, frequency division resource number, transmission period, and the time division resource number, code division resource number, and corresponding orthogonal code groups, starting frequency domain reference point, starting frequency domain offset, and sequence parameters of RIM-RS based on mutual inspection requirements, protocol version, and protocol constraints, the specific configuration of each parameter can be as follows. The configurations shown below are merely examples and are not intended to be limiting: The subcarrier spacing of RIM-RS can be configured according to the protocol version and interaction requirements, such as 30 kHz. The number of frequency division resources can be configured to 4 (since the cell bandwidth is 100 Mbps, the maximum number of frequency division resources can be configured to 4, which is 4 * 20 Mbps). The sending period can be configured according to mutual inspection requirements, protocol version, and protocol constraints; for example, it can be configured to 10 milliseconds. The number of time-division resources within a transmission cycle can be configured according to interaction requirements and protocol constraints. For example, it can be configured as an 8:2 ratio, meaning there are two available time-domain locations, or two special time slots, within 10 milliseconds. The number of code division resources can be configured according to interaction requirements and protocol constraints. For example, the protocol constraints stipulate that the maximum number of available RIM-RS resources within 10 milliseconds is 32, the number of time division resources is 2, and the number of frequency division resources is 4. Therefore, the number of code division resources can be configured to 4. The number of orthogonal codes in an orthogonal code group can correspond to the number of code division resources, and each specific orthogonal code can be set according to the protocol version and protocol constraints. The initial frequency domain reference point can be configured according to protocol constraints and mutual testing requirements; for example, it can be configured as frequency domain reference point PointA. The starting frequency domain offset can be the offset of the RIM-RS starting frequency domain resource block relative to the starting frequency domain reference point. It can be determined according to the mutual inspection requirements, for example, it can be 10 resource blocks (RB). Sequence parameters can be configured according to the protocol version and protocol constraints. For example, the sequence type in the sequence parameters can be configured as a Gold sequence or a ZC sequence, etc.

[0050] It should be noted that parameters such as time fraction and frequency fraction can be dynamically adjusted according to the actual deployment scenario (such as a high-density network equipment environment) to adapt to different network requirements.

[0051] Step 203: Based on the subcarrier spacing and the number of frequency division resources, determine the frequency division resource bandwidth of RIM-RS, and based on the starting frequency domain reference point, the starting frequency domain offset, and protocol constraints, determine the starting frequency domain resource location of RIM-RS.

[0052] In some embodiments, the product of the subcarrier spacing and the number of frequency division resources can be determined, and then this product can be used to determine the frequency division resource bandwidth of the RIM-RS. That is, the RIM-RS can consist of a number of frequency division resource subcarriers to accommodate different bandwidth requirements.

[0053] In some embodiments, the starting frequency domain resource block number can be determined based on the starting frequency domain reference point and the starting frequency domain offset, and the number of subcarriers in the frequency domain resource block can be determined based on protocol constraints. Then, the product of the starting frequency domain resource block number, the number of subcarriers, and the subcarrier spacing is added to the center frequency of the starting frequency domain reference point to obtain the starting frequency domain resource location of the RIM-RS. For example, the formula for calculating the starting frequency domain resource location can be as follows, where the following formula is merely an example and not intended to be limiting:

[0054] in, The center frequency of the initial frequency domain reference point. The starting frequency domain resource block number. The number of subcarriers within each resource block The subcarrier spacing.

[0055] It should be noted that when determining the starting frequency domain resource block number, the starting frequency domain reference point can be used as the starting point, and the resource blocks can be numbered incrementally starting from 0.

[0056] In some embodiments, when determining the frequency domain offset based on the starting frequency domain reference point, PointA is the absolute frequency domain reference according to the protocol version and protocol constraints. When the starting frequency domain reference point is PointA, the frequency domain offset is the absolute frequency of PointA.

[0057] Step 204: Determine the status of the near and far detection function of RIM-RS based on the mutual inspection requirements. Combine the number of time-division resources, protocol version, protocol constraints, and the status of the near and far detection function to determine the transmission position of the time domain resources of RIM-RS within the transmission period.

[0058] The proximity detection function controls whether to differentiate between different types of interference detected by network devices (e.g., near-field or far-field interference). Its status can be either off or on, depending on the mutual detection requirements. In other words, when proximity detection is off, interference types are not differentiated; when it is on, interference types are differentiated.

[0059] In some embodiments, since the application scenario of this disclosure is remote interference detection of network devices under atmospheric waveguides, the near-far detection function can be configured to be enabled.

[0060] In some embodiments, when determining the transmission position of the time-domain resources of RIM-RS within a transmission period by combining the number of time-division resources, protocol version, protocol constraints, and the status of the near-far detection function, the number of consecutive symbols used by RIM-RS within a transmission period can be determined first based on the protocol version and protocol constraints, and then the transmission position of the time-domain resources of RIM-RS within a transmission period can be determined based on the number of time-division resources, the status of the near-far detection function, and the number of consecutive symbols.

[0061] Here, the symbol refers to the OFDM symbol. OFDM is an abbreviation for Orthogonal Frequency Division Multiplexing.

[0062] It should be noted that the transmission position of the time domain resources of RIM-RS within the transmission cycle varies depending on the state of the near-far detection function.

[0063] In some embodiments, when the near-far detection function is off, the last few consecutive symbols in a special time slot of the transmission period can be determined as the transmission position of the time domain resource.

[0064] In some embodiments, when the near-far detection function is enabled, in the near field, the last few consecutive symbols in a special time slot can be determined as the transmission location of the time domain resource; or in the far field, the last few consecutive symbols in the preceding time slot adjacent to the special time slot can be determined as the transmission location of the time domain resource.

[0065] It should be noted that near-field and far-field attributes can be pre-assigned to network devices based on actual conditions. For example, near-field or far-field attributes can be pre-assigned to network devices based on the network device deployment topology. Alternatively, after receiving a RIM-RS signal from a transmitting network device, the receiving network device can determine whether the transmitting network device is experiencing near-field or far-field interference through relevant judgments such as power and latency, and feed this information back to the transmitting end so that it can update its own attributes. This disclosure does not limit this approach.

[0066] For example, based on the protocol version and protocol constraints, the number of consecutive symbols used by RIM-RS within a transmission period is determined to be 2, and the number of time-division resources is 2, meaning that RIM-RS can use 2 special time slots within a transmission period. Then, based on the number of consecutive symbols, the number of time-division resources, and the status of the near / far detection function, the transmission position of the time-domain resources of RIM-RS within the transmission period can be determined. Specifically, when the near / far detection function is disabled, the last two consecutive symbols in the special time slot of the transmission period can be determined as the transmission position of the time-domain resources. When the near / far detection function is enabled, in the near field, the last two consecutive symbols in the special time slot are determined as the transmission position, or in the far field, the last two consecutive symbols in the preceding time slot adjacent to the special time slot are determined as the transmission position.

[0067] Step 205: For each orthogonal code in the orthogonal code group, determine the associated network device identifier, scrambling identifier, and associated scrambling parameters.

[0068] Among them, the network device identifier can be used to identify the network device, and its specific form can be set as needed. For example, the network device identifier can be the network device code, etc. This disclosure does not limit it.

[0069] The scrambling identifier can be associated with the orthogonal code and the scrambling parameters respectively, thus forming an association relationship of "orthogonal code-scrambling identifier-scrambling parameters". The specific form can be set as needed, and this disclosure does not limit it.

[0070] In some embodiments, when determining the associated scrambling identifier for each orthogonal code, a two-level scrambling identifier can be set. The first level is a network device-level scrambling identifier, used for cross-network device differentiation. The second level is a scrambling identifier for multiple instances within a network device, which can differentiate multiple instances within the same network device, adapting to scenarios with multiple interference sources or multiple antennas, and meeting the measurement requirements of the same network device for multiple interference sources and multiple antennas. For example, the second-level scrambling identifier can be 0, 100, 200, 300, etc., and this disclosure does not limit it.

[0071] The scrambling parameters are parameters used to generate scrambling sequences to scramble the base sequences of RIM-RS, and they can be configured as needed. For example, scrambling parameters may include linear coefficients, offset coefficients, scrambling sequence length, etc., which are not limited in this disclosure.

[0072] In this disclosure, each orthogonal code in the orthogonal code group determines the associated network device identifier, scrambling identifier, and associated scrambling parameters, thereby forming an association relationship between the network device, the orthogonal code, and the scrambling parameters. When the network device receives the RIM-RS, it can efficiently and quickly obtain the sender's identity and scrambling parameters based on this association relationship to generate a localized signal to verify the RIM-RS signal, thus improving efficiency.

[0073] Step 206: Generate configuration parameters based on all parameters determined sequentially.

[0074] In some embodiments, at least one of the following can be configured based on mutual inspection requirements: the status of the indicator indicating whether the interference avoidance effect is sufficient, the multiplier factor of the RIM-RS scrambling timer, and the bias.

[0075] For example, based on mutual inspection requirements, the status of the indicator indicating whether the interference avoidance effect is sufficient can be configured to be off, and the multiplier factor and bias of the scrambling timer of RIM-RS can both be configured to 0.

[0076] In some embodiments, the number of transmission resources available to RIM-RS during a transmission cycle is currently constrained by the protocol. Therefore, the product of the number of time-division resources, frequency-division resources, and code-division resources can also be determined as the number of time-frequency resources that can be allocated within the transmission cycle of RIM-RS. That is, time-division resources × frequency-division resources × code-division resources. While keeping the frequency-division and code-division resources unchanged, increasing the number of time-division resources can directly increase the number of RIM-RS resources that can be supported. This allows more network devices to participate in the mutual inspection process, effectively providing mutual inspection capabilities in high-density network device deployment scenarios.

[0077] Then, in order for network devices to accurately identify the type of interference from the sender of the received RIM-RS signal, the time-frequency resources mapped to the first interference type identifier and the second interference type identifier can be determined based on mutual inspection requirements and the number of time-frequency resources.

[0078] Wherein, the first interference type identifier is the interference identifier and the second interference type identifier is the interference identifier, or the first interference type identifier can be the interference identifier and the second interference type identifier can be the interference identifier; this disclosure does not limit this.

[0079] Among them, interference and being interfered with are the types of interference that a network device can cause to other network devices in a remote interference scenario. Interference is interfering with other network devices, and being interfered with is being interfered with by other network devices.

[0080] The specific implementation of the first interference type identifier and the second interference type identifier can be set as needed, and this disclosure does not limit them.

[0081] By configuring the above parameters, configuration parameters are generated, enabling the configuration of parameters such as the RIM-RS sequence, time-frequency resources, and interference type. This ensures that equipment from different manufacturers generates consistent RIM-RS signals under the same channel conditions, providing a basis for different manufacturers to accurately and reliably detect and identify each other's signals.

[0082] For example, some of the generated configuration parameters can be shown in Table (1) below. The parameters shown in Table (1) are just examples. The configuration parameters of RIM-RS include, but are not limited to, the parameters shown in Table (1). The standardized configuration of each parameter in Table (1) is also just an example. The specific parameters can be set according to actual needs. In addition, Table (1) uses the RIM-RS setting parameters of two manufacturers as examples. The specific manufacturers and their setting parameters should also be set according to the actual situation. In addition, the RIM-RS transmission period is set as 10 milliseconds (ms) as an example. There is no limitation here. In Table (1), RB is short for Resource Block, Near-Far is a near-far detection function, Sslot is short for Special Slot, and Dslot is short for Downlink Slot.

[0083] Table (1)

[0084] In the RIM-RS code division configuration, sequences 0, 1, 2, and 3 can be RIM-RS sequence indices for multiple instance-level (e.g., multiple antennas) within the network device. The index and identifier corresponding to each instance can be set as needed, and there are no restrictions here.

[0085] Step 207: Send the configuration parameters to network devices from different manufacturers.

[0086] The specific implementation of step 207 can be found in the detailed descriptions of other embodiments in this disclosure, and will not be repeated here.

[0087] In this embodiment, firstly, based on the obtained setting parameters of Remote Interference Management Reference Signals (RIM-RS) from different manufacturers and the mutual inspection requirements of network devices between different manufacturers, the parameters to be standardized for RIM-RS and the protocol version and protocol constraints used for standardized configuration are determined. Then, based on the mutual inspection requirements, protocol version, and protocol constraints, the subcarrier spacing, frequency division resources, transmission period, and the time division resources, code division resources, and corresponding orthogonal code groups, starting frequency domain reference points, and sequence parameters of RIM-RS are determined. Finally, based on the subcarrier spacing and frequency division resources... The process involves determining the frequency division resource bandwidth of RIM-RS, and based on the initial frequency domain reference point, protocol constraints, and mutual detection requirements, determining the initial frequency domain resource location of RIM-RS. Then, based on the mutual detection requirements, the status of the near-far detection function of RIM-RS is determined. Combining the number of time-division resources, protocol version, protocol constraints, and the status of the near-far detection function, the transmission position of the time-domain resources of RIM-RS within the transmission period is determined. For each orthogonal code in the orthogonal code group, an associated network device identifier, scrambling identifier, and associated scrambling parameters are determined. Finally, based on all the sequentially determined parameters, configuration parameters are generated. This allows for the unified setting of key parameters of the RIM-RS signal (such as subcarrier spacing, frequency domain offset, number of code division resources, scrambling identifier, etc.), ensuring the consistency of RIM-RS signals generated by equipment from different manufacturers in the time and frequency domains, thereby providing conditions for reliable identification and detection between base stations from different manufacturers.

[0088] Figure 3 This is a schematic flowchart of a network device mutual detection method provided in an embodiment of the present disclosure.

[0089] like Figure 3 As shown, the network device mutual detection method is executed by the first network device and may include the following steps: Step 301: When the remote interference detection condition is detected, a first RIM-RS signal is generated based on the configuration parameters of the remote interference management reference signal RIM-RS.

[0090] The configuration parameters are generated based on the parameter standardization configuration method of the reference signal in the above embodiments of this disclosure.

[0091] The first network device can be the first base station.

[0092] The remote interference detection conditions can be set according to actual needs. For example, they can be at least one of the following: the transmission time of the current RIM-RS signal transmission cycle, abnormal received signal power, etc. This disclosure does not limit them.

[0093] The first RIM-RS signal can be used for remote interference detection.

[0094] In this disclosure, when a remote interference detection condition is detected, the configuration parameters of the RIM-RS can be obtained to generate a first RIM-RS signal, thereby performing remote interference detection.

[0095] In some embodiments, when generating the first RIM-RS signal based on the configuration parameters of the Remote Interference Management Reference Signal (RIM-RS), it can be generated based on OFDM technology.

[0096] Step 302: Send the first RIM-RS signal.

[0097] In this disclosure, after generating the first RIM-RS signal, the first network device can send the first RIM-RS signal.

[0098] In some embodiments, when the first network device transmits the first RIM-RS signal, it may first determine the transmission power of the first RIM-RS signal, and finally transmit the first RIM-RS signal based on the transmission power.

[0099] It should be noted that the specific implementation of determining the transmission power of the first RIM-RS signal can be set according to actual needs, and this disclosure does not limit it.

[0100] For example, in some embodiments, the transmit power of the RIM-RS signal can be determined by the following formula, which is merely an example and not intended to be limiting:

[0101] in, The preset reference power, The distance between base stations The preset path loss coefficient is typically set to 3.5 dB / km.

[0102] It should be noted that, , as well as The value can be set according to actual needs, and this disclosure does not impose any restrictions on it.

[0103] Step 303: Receive the second RIM-RS signal and determine the orthogonal code of the second RIM-RS signal.

[0104] The second RIM-RS signal can be a feedback signal from a second network device. This second network device can be a second base station, which can be any network device other than the current first network device.

[0105] In this disclosure, after receiving the second RIM-RS signal, in order to verify the second RIM-RS signal, the second RIM-RS signal can first be demodulated to obtain the demodulated sequence, and then the orthogonal characteristic analysis can be performed on the demodulated sequence. Based on the orthogonal code configured in the configuration parameters, the orthogonal code of the second RIM-RS signal can be determined.

[0106] In some embodiments, after receiving the second RIM-RS signal and before determining the orthogonal code of the second RIM-RS signal, the channel environment can be equalized to compensate for the received second RIM-RS signal, thereby eliminating the effects of multipath fading, path loss, noise and interference on the signal.

[0107] It should be noted that the specific implementation of equalization of the channel environment can be set according to actual needs, and this disclosure does not limit it.

[0108] For example, in some embodiments, the LMS algorithm can be used to equalize the signal environment, and its update formula is as follows, where the following formula is only an example and is not intended to be limiting: , in, These are the filter coefficients. Step size factor This is the error signal, i.e., the deviation between the pilot signal and the second RIM-RS signal. The input signal is the second RIM-RS signal.

[0109] Therefore, based on To compensate for the second RIM-RS signal.

[0110] LMS stands for Least Mean Square (LMS) algorithm.

[0111] Among them, the pilot signal is a known reference signal pre-agreed upon by the transmitting and receiving network devices, and its waveform, time and frequency position, and sequence structure are clearly configured at both the transmitting and receiving ends.

[0112] Step 304: Generate a verification signal based on the orthogonal code and configuration parameters.

[0113] The verification signal can be a localized RIM-RS signal generated by the first network device, which can be used to verify the second RIM-RS signal.

[0114] In this disclosure, after determining the orthogonal code in the second RIM-RS signal, standardized parameters such as scrambling parameters associated with the scrambling identifier corresponding to the orthogonal code can be obtained from the configuration parameters. Then, a verification signal is generated based on the relevant parameters to provide conditions for verifying the second RIM-RS signal.

[0115] Specifically, in some embodiments, when the scrambling identifier is a two-level mechanism, the corresponding first-level scrambling identifier, i.e., the base station-level scrambling identifier, can be determined first by orthogonal codes. Then, the demodulated RIM-RS sequence is analyzed to determine the sequence index, and the second-level scrambling identifier corresponding to the sequence index is obtained from the configuration parameters. The scrambling parameters within the scrambling identifier are obtained. This disclosure does not limit this.

[0116] Step 305: If the correlation between the second RIM-RS signal and the verification signal is greater than a threshold, based on the interference type identifier of the time-frequency resource mapping where the second RIM-RS signal is located in the configuration parameters, and the identifier of the second network device associated with the orthogonal code, determine the remote interference identity of the second network device relative to the first network device.

[0117] Among them, correlation can be used to represent the degree of correlation between the second RIM-RS signal and the verification signal.

[0118] The threshold value can be a critical correlation value used to determine the correlation between the second RIM-RS signal and the verification signal. It can be set according to actual needs, and this disclosure does not limit it. That is, if the correlation is greater than the threshold, it can be determined that the second RIM-RS signal and the verification signal are highly correlated, and if the correlation is less than or equal to the threshold, it can be determined that the second RIM-RS signal and the verification signal are less correlated.

[0119] The identifier of the second network device can be used to characterize the second network device, and its form can be determined as needed. For example, the identifier of the second network device can be the code of the network device, etc., and this disclosure does not limit it in this way.

[0120] It should be noted that the manufacturer of the second network device may be different from the manufacturer of the first network device.

[0121] The interference type identifier can be used to characterize the type of interference, which can be either the type of interference or the type of interference. The specific form can be set according to actual needs, and this disclosure does not limit it.

[0122] The identity of the remote interference source can be either the identity of the interference source or the identity of the interference source. The specific identity can be determined according to the actual situation, and this disclosure does not limit it.

[0123] In this disclosure, when the correlation between the second RIM-RS signal and the verification signal is greater than a threshold, it can be determined that the second RIM-RS signal and the verification signal have a high degree of correlation. In this case, it can be determined that the second RIM-RS signal was sent by the network device corresponding to the verification signal. Therefore, based on the interference type identifier of the time-frequency resource mapping where the second RIM-RS signal is located in the configuration parameters, and the identifier of the second network device associated with the orthogonal code, the remote interference identity of the second network device corresponding to that identifier relative to the first network device can be determined. For example, if the interference type identifier of the time-frequency resource mapping where the second RIM-RS signal is located is a scrambling type identifier, the remote interference identity of the second network device corresponding to that network device identifier relative to the current first network device can be determined as the scrambling source identity. This disclosure does not limit this aspect.

[0124] In this embodiment, a remote interference detection condition is first detected. Based on the configuration parameters of the Remote Interference Management Reference Signal (RIM-RS), a first RIM-RS signal is generated and transmitted. Then, a second RIM-RS signal is received, and its orthogonal code is determined. Next, a verification signal is generated based on the orthogonal code and configuration parameters. Finally, if the correlation between the second RIM-RS signal and the verification signal is greater than a threshold, the remote interference identity of the second network device relative to the first network device is determined based on the interference type identifier of the time-frequency resource mapping where the second RIM-RS signal is located in the configuration parameters, and the identifier of the second network device associated with the orthogonal code. Thus, by generating and transmitting RIM-RS signals using standardized configuration parameters, and identifying RIM-RS signals transmitted by other network devices, the problem of incompatibility between network devices from different manufacturers due to protocol inconsistencies and parameter incompatibility is solved. This enables inter-vendor inter-vendor network device inter-vendor testing, making it applicable to more scenarios and improving its compatibility and applicability.

[0125] Figure 4 This is a schematic flowchart of a network device mutual detection method provided in an embodiment of the present disclosure.

[0126] like Figure 4 As shown, the network device mutual detection method is executed by the first network device and may include the following steps: Step 401: Upon detecting the triggering of remote interference detection conditions, the base sequence of the first RIM-RS signal is generated based on the configured sequence parameters according to the requirements of the configured protocol version.

[0127] The requirements for the protocol version may include sequence generation rules.

[0128] In this disclosure, after detecting the triggering of remote interference detection conditions, the base sequence of the first RIM-RS signal can be generated based on the configured sequence parameters according to the requirements of the configured protocol version, thereby providing a basis for generating the first RIM-RS signal.

[0129] Step 402: Based on the orthogonal code associated with the currently configured first network device, the base sequence is orthogonalized to obtain the orthogonalized sequence.

[0130] In this disclosure, after generating the base sequence of the first RIM-RS signal, in order to distinguish the RIM-RS signals sent by different network devices, the base sequence can first be orthogonalized based on the orthogonal code configured by the current first network device to obtain the orthogonalized sequence.

[0131] Step 403: Based on the scrambling parameters associated with the scrambling identifier configured by the orthogonal code, the orthogonalized sequence is scrambled to obtain the first scrambled RIM-RS sequence.

[0132] In this disclosure, after generating the base sequence of the first RIM-RS signal, in order to further distinguish the RIM-RS signals sent by different network devices, the orthogonalized sequence can be scrambled based on the scrambling parameters associated with the scrambling identifier corresponding to the orthogonal code to obtain the scrambled first RIM-RS sequence.

[0133] In some embodiments, the product of the first scrambling parameter and the i-th sequence index can be first added to the second scrambling parameter, and then a modulo operation can be performed on the sum obtained based on the modulus to obtain the value corresponding to the i-th sequence index, where i is a positive integer less than the length of the base sequence, and the modulus is determined based on the length of the scrambling sequence in the scrambling parameters. Then, based on the values ​​corresponding to all sequence indices, the corresponding scrambling sequence is generated. The formula for generating the scrambling sequence can be as follows, where the following formula is only an example and is not intended to be limiting:

[0134] in, The first scrambling parameter, This is the second scrambling parameter. The length of the scrambling sequence is typically 16 bits or 32 bits.

[0135] Finally, based on the scrambling sequence, the orthogonalized sequence is scrambled again to generate the first scrambled RIM-RS sequence, thereby further distinguishing the RIM-RS signals of different network devices.

[0136] Step 404: Modulate the first RIM-RS sequence according to the preset modulation method to generate a modulated signal.

[0137] The modulation method can be the way the RIM-RS signal is modulated, and it can be determined according to the configured protocol version. For example, the modulation method can be QPSK or 16QAM, and this disclosure does not limit it.

[0138] QPSK is short for Quadrature Phase Shift Keying (QPSK).

[0139] 16QAM is an abbreviation for 16-Quadrature Amplitude Modulation (16QAM).

[0140] Step 405: Based on the currently triggered remote interference detection conditions, the time-frequency resource configuration in the configuration parameters, and the status of the near and far detection function, the modulated signal is mapped onto the corresponding time-frequency resource block to generate the first RIM-RS signal.

[0141] In this disclosure, after modulating the first RIM-RS sequence to obtain the modulated signal, the modulated signal can be mapped onto the corresponding time-frequency resource block to generate the first RIM-RS signal based on the currently triggered remote interference detection condition, the time-frequency resource configuration in the configuration parameters, and the status of the near-far detection function. For example, if the currently triggered remote interference detection condition is abnormal received signal power, it can be determined that the first network device is being interfered with by the signal of another network device. In this case, the modulated signal can be mapped onto the time-frequency resource block corresponding to the interference type based on the time-frequency resource configuration in the configuration parameters and the status of the near-far detection function to generate the first RIM-RS signal.

[0142] Step 406: Send the first RIM-RS signal.

[0143] Step 407: Receive the second RIM-RS signal and determine the orthogonal code of the second RIM-RS signal.

[0144] Step 408: Generate a verification signal based on the orthogonal code and configuration parameters.

[0145] Step 409: If the correlation between the second RIM-RS signal and the verification signal is greater than a threshold, based on the interference type identifier of the time-frequency resource mapping where the second RIM-RS signal is located in the configuration parameters, and the identifier of the second network device associated with the orthogonal code, determine the remote interference identity of the second network device relative to the first network device.

[0146] The specific implementation of steps 406 to 409 can be found in the detailed descriptions of other embodiments in this disclosure, and will not be repeated here.

[0147] In this embodiment, upon detecting a remote interference detection condition, a base sequence of a first RIM-RS signal is generated based on the configured sequence parameters according to the requirements of the configured protocol version. The base sequence is orthogonalized based on the configured orthogonal code associated with the current first network device, resulting in an orthogonalized sequence. The orthogonalized sequence is scrambled based on the scrambling parameters associated with the scrambling identifier configured in the orthogonal code, resulting in a scrambled first RIM-RS sequence. The first RIM-RS sequence is modulated according to a preset modulation scheme to generate a modulated signal. Based on the currently triggered remote interference detection condition, the time-frequency resource configuration in the configuration parameters, and the status of the near / far detection function, the modulated signal is mapped to the corresponding time-frequency resource block to generate the first RIM-RS signal. The first RIM-RS signal is then transmitted. A second RIM-RS signal is received, and its orthogonal code is determined. A verification signal is generated based on the orthogonal code and the configuration parameters. When the correlation between the second RIM-RS signal and the verification signal exceeds a threshold, the remote interference identity of the second network device relative to the first network device is determined based on the interference type identifier of the time-frequency resource mapping where the second RIM-RS signal is located in the configuration parameters, and the identifier of the second network device associated with the orthogonal code. Therefore, when network devices need to perform remote interference detection, they can directly generate RIM-RS signals using pre-configured standardized parameters for detection. This allows network devices from other manufacturers receiving the signal to quickly and efficiently identify the interference, thereby improving the efficiency of network device inter-detection.

[0148] Figure 5 This is a schematic flowchart of a network device mutual detection method provided in an embodiment of the present disclosure.

[0149] like Figure 5 As shown, this network device mutual detection method is performed by a second network device and may include the following steps: Step 501: Based on the time-frequency resource configuration in the RIM-RS configuration parameters, detect whether the first RIM-RS signal exists on the corresponding time-frequency resource within the current detection period.

[0150] The second network device may be a second base station, which may belong to a different manufacturer than the first network device, or it may belong to the same manufacturer. This disclosure does not limit this.

[0151] The configuration parameters are generated based on the parameter standardization configuration method of the reference signal in the above embodiments of this disclosure.

[0152] The detection period can be the period for detecting the RIM-RS signal, and its duration can be set according to actual needs. This disclosure does not limit it.

[0153] In this disclosure, based on the time-frequency resource configuration in the RIM-RS configuration parameters, the presence of a first RIM-RS signal is detected on the corresponding time-frequency resource within the current detection period.

[0154] Step 502: If a first RIM-RS signal exists, determine the orthogonal code of the first RIM-RS signal.

[0155] Step 503: Generate a verification signal based on the orthogonal code and configuration parameters.

[0156] Step 504: If the correlation between the first RIM-RS signal and the verification signal is greater than a threshold, obtain the first network device identifier associated with the orthogonal code and the interference type identifier of the time-frequency resource mapping where the first RIM-RS signal is located from the configuration parameters, and determine the first remote interference identity of the first network device corresponding to the identifier relative to the current second network device.

[0157] In this disclosure, when determining the remote interference identity of the first network device relative to the current second network device based on the interference type identifier of the time-frequency resource mapping where the first RIM-RS signal is located, if the interference type identifier of the time-frequency resource mapping where the first RIM-RS signal is located is an intruding type, the first remote interference identity of the first network device relative to the current second network device is an intruding source; or if the interference type identifier of the time-frequency resource mapping where the first RIM-RS signal is located is a stalked type, the first remote interference identity of the first network device relative to the current second network device is a stalked source. The specific identity can be determined according to the actual situation, and this disclosure does not limit it.

[0158] Step 505: Based on the configuration parameters, generate a second RIM-RS signal and return it to the first network device.

[0159] In some embodiments, when a second RIM-RS signal is generated based on configuration parameters and returned to the first network device, a base sequence of the second RIM-RS signal is generated based on the configuration parameters, and the base sequence is orthogonalized and scrambled to obtain a scrambled sequence. Based on a preset modulation method, the scrambled sequence is modulated to obtain a modulated signal. Based on the time-frequency resource configuration and the status of the near-far detection function in the configuration parameters, the modulated signal is mapped to the time-frequency resource block corresponding to the second remote interference identity to generate the second RIM-RS signal, wherein the second remote interference identity is the opposite of the first remote interference identity. Finally, the second RIM-RS signal is sent to the first network device.

[0160] The second RIM-RS signal is the feedback signal of the current second network device.

[0161] The specific implementation of steps 502 to 505 can be found in the detailed descriptions of other embodiments in this disclosure, and will not be repeated here.

[0162] In this embodiment, firstly, based on the time-frequency resource configuration in the RIM-RS configuration parameters, the system detects whether a first RIM-RS signal exists on the corresponding time-frequency resource within the current detection period. If a first RIM-RS signal exists, its orthogonal code is determined. Then, based on the orthogonal code and configuration parameters, a verification signal is generated. If the correlation between the first RIM-RS signal and the verification signal is greater than a threshold, the system obtains the first network device identifier associated with the orthogonal code and the interference type identifier of the time-frequency resource mapping where the first RIM-RS signal is located from the configuration parameters. The system determines the first remote interference identity of the first network device corresponding to this identifier relative to the current second network device. Finally, based on the configuration parameters, a second RIM-RS signal is generated and returned to the first network device. Thus, when a network device detects a RIM-RS signal sent by another network device, it identifies and detects the signal based on pre-configured standardized and unified configuration parameters to complete interference detection and determine its own interference identity, providing feedback to the corresponding network device. This reduces the complexity of inter-network device mutual detection and improves the convenience of system deployment and maintenance.

[0163] The following is combined with Figure 6 The system architecture of the network device mutual inspection method proposed in this disclosure is illustrated with an example. Figure 6 This is a schematic diagram of the system architecture of the network device mutual inspection method proposed in this disclosure.

[0164] like Figure 6 As shown, the system 600 includes: a first network device 601, a second network device 602, and a channel environment.

[0165] Taking the first network device as the transmitter and the second network device as the receiver as an example, the workflow of this system 600 can be as follows: The receiver generates a reference signal according to the pre-configured parameters and transmits it on the configured time-frequency resources. The receiver detects the received RIM-RS signal to determine whether there are signals from other network devices and completes the mutual detection process accordingly. Thus, through unified resource allocation and parameter configuration, the interoperability and stability of multi-base station systems in atmospheric waveguide environments are significantly improved.

[0166] Specifically, in some embodiments, the specific structure of the first network device or the second network device may be as follows: Figure 7 As shown, Figure 7 This is a schematic diagram of the network device structure in the network device mutual testing system proposed in this disclosure, wherein, Figure 7 The network device shown is either the first network device or the second network device. The structure shown is only an example, and the specific configuration can be set according to actual needs. No restrictions are imposed here.

[0167] like Figure 7 As shown, the network device 700 includes: a signal transceiver module 701, a signal generation module 702, a modulation and coding module 703, a resource mapping module 704, a physical layer processing module 705, a channel equalization module 706, a demodulation and decoding module 707, and a detection module 708.

[0168] Among them, the signal transceiver module 701 can send and receive RIM-RS signals; The signal generation module 702 can generate RIM-RS signals according to the configuration parameters of a unified standard; The modulation and coding module 703 can adopt different modulation schemes (QPSK or 16QAM) to adapt to different channel environments; Resource mapping module 704 can map RIM-RS signals to corresponding time-frequency resources; The physical layer processing module 705 can be responsible for signal scrambling and power control; The channel equalization module 706 can be used to equalize the channel environment; The demodulation and decoding module 707 can be used to demodulate and decode RIM-RS signals; The detection module 708 can be used to determine whether there are signals from other base stations and to complete the mutual detection process.

[0169] It should be noted that the structure of the first or second network device in the network device mutual testing system proposed in this disclosure includes, but is not limited to, the following: Figure 7 The structure and the deployment order of each module can be set according to actual needs, and this disclosure does not limit them.

[0170] It should be noted that when the network device is either a sender or a receiver, it can be used as needed. Figure 7 The modules shown, in whole or in part, may include, for example, when the network device is the transmitter, primarily including, but not limited to, a signal transceiver module 701, a signal generation module 702, a modulation and coding module 703, a resource mapping module 704, and a physical layer processing module 705. When the network device is the receiver, it may primarily include, but not limited to, a signal transceiver module 701, a channel equalization module 706, a demodulation and decoding module 707, and a detection module 708. This disclosure does not limit the scope of the application.

[0171] for Figure 6In the channel environment, specifically the atmospheric waveguide environment, signal propagation is affected by multipath effects, fading, and interference. To improve the detection capability of RIM-RS signals, the system employs adaptive equalization algorithms, such as the LMS algorithm, to eliminate channel-induced distortion.

[0172] In some embodiments, the parameter standardization configuration method for reference signals and the network device mutual testing method proposed in this disclosure can be applied to standard LTE, 5G NR, or Wi-Fi 6 communication systems. Similar functionality can be achieved simply by adjusting the generation and transmission mechanism of the RIM-RS according to the parameter configuration rules of the corresponding system. This disclosure does not limit the scope of the application.

[0173] Among them, LTE is short for Long-Term Evolution, 5G NR is short for 5th Generation New Radio, and Wi-Fi 6 is short for sixth generation Wi-Fi.

[0174] To implement the above embodiments, this disclosure also proposes a parameter standardization configuration device for a reference signal.

[0175] Figure 8 This is a schematic diagram of the structure of a parameter standardization configuration device for a reference signal provided in an embodiment of this disclosure.

[0176] like Figure 8 As shown, the parameter standardization configuration device 800 for the reference signal includes: The first determining module 801 is used to determine the parameters to be standardized for RIM-RS and the protocol version and protocol constraints used for standardized configuration based on the setting parameters of the Remote Interference Management Reference Signal (RIM-RS) from different manufacturers and the mutual inspection requirements of network devices between different manufacturers. The first generation module 802 is used to generate configuration parameters corresponding to the parameters to be standardized based on the protocol version and protocol constraints. The first sending module 803 is used to send configuration parameters to network devices from different manufacturers.

[0177] In one possible implementation of this disclosure, the first generation module 802 is specifically used for: Based on mutual inspection requirements, protocol version and protocol constraints, the subcarrier spacing, frequency division resource number, transmission period, and time division resource number, code division resource number and corresponding orthogonal code group, starting frequency domain reference point and starting frequency domain offset, and sequence parameters of RIM-RS are determined. Based on the subcarrier spacing and the number of frequency division resources, the frequency division resource bandwidth of RIM-RS is determined, and based on the starting frequency domain reference point, the starting frequency domain offset, and the protocol constraints, the starting frequency domain resource location of RIM-RS is determined. Based on the mutual inspection requirements, the status of the near and far detection function of RIM-RS is determined. Combining the number of time-division resources, protocol version, protocol constraints, and the status of the near and far detection function, the transmission position of the time domain resources of RIM-RS within the transmission period is determined. For each orthogonal code in the orthogonal code group, determine the associated network device identifier, scrambling identifier, and associated scrambling parameters; Based on all the parameters determined in sequence, configuration parameters are generated.

[0178] In one possible implementation of this disclosure, the first generation module 802 is specifically used for: The product of the subcarrier spacing and the number of frequency division resources is determined, and this product is used to determine the frequency division resource bandwidth of RIM-RS; Based on the initial frequency domain reference point and the initial frequency domain offset, the initial frequency domain resource block number is determined, and the number of subcarriers in the frequency domain resource block is determined based on protocol constraints. The starting frequency domain resource location of RIM-RS is obtained by adding the product of the starting frequency domain resource block number, the number of subcarriers, and the subcarrier spacing to the center frequency of the starting frequency domain reference point.

[0179] In one possible implementation of this disclosure, the first generation module 802 is specifically used for: Based on the protocol version and protocol constraints, determine the number of consecutive symbols used by RIM-RS within a transmission cycle; Based on the number of time-division resources, the status of near and far detection functions, and the number of consecutive symbols, the transmission position of the time-domain resources of RIM-RS within the transmission cycle is determined.

[0180] In one possible implementation of this disclosure, the first generation module 802 is specifically used for at least one of the following: When the near-far detection function is off, the last few consecutive symbols in a special time slot of the transmission period are determined as the transmission position of the time domain resource. When the near and far detection function is enabled, in the near field, the last few consecutive symbols in a special time slot are determined as the transmission position of the time domain resource; or in the far field, the last few consecutive symbols in the preceding time slot adjacent to the special time slot are determined as the transmission position of the time domain resource.

[0181] In one possible implementation of this disclosure, the first generation module 802 is further configured to: Based on mutual inspection requirements, at least one of the following is configured: the status of the indicator indicating whether the interference avoidance effect is sufficient, the multiplier factor of the scrambling timer of RIM-RS, and the bias.

[0182] In one possible implementation of this disclosure, the first generation module 802 is further configured to: The product of the time-division resource number, frequency-division resource number, and code-division resource number is determined, and this product is used to determine the number of time-frequency resources that can be allocated within the transmission cycle of RIM-RS. Based on mutual inspection requirements and the number of time-frequency resources, the time-frequency resources mapped to the first interference type identifier and the second interference type identifier are determined respectively.

[0183] The functions and specific implementation principles of the modules described in this embodiment can be found in the above method embodiments, and will not be repeated here.

[0184] In this embodiment, firstly, based on the obtained setting parameters of Remote Interference Management Reference Signals (RIM-RS) from different manufacturers and the mutual inspection requirements of network devices from different manufacturers, the parameters to be standardized for RIM-RS, as well as the protocol version and protocol constraints used for standardized configuration, are determined. Then, based on the mutual inspection requirements, protocol version, and protocol constraints, configuration parameters corresponding to the parameters to be standardized are generated. Finally, the configuration parameters are sent to network devices from different manufacturers. Thus, by standardizing and unifying the configuration of RIM-RS parameters through the mutual inspection requirements of network devices from different manufacturers and the protocol version and protocol constraints, it is possible to ensure that network devices from different manufacturers can accurately identify and detect each other's signals, providing conditions for accurate and reliable detection and identification between network devices from different manufacturers.

[0185] Figure 9 This is a schematic diagram of the network device mutual detection device provided in the embodiments of this disclosure.

[0186] like Figure 9 As shown, the network device mutual testing device 900 is configured in the first network device and includes: The second generation module 901 is used to detect the triggering conditions for remote interference detection and generate a first RIM-RS signal based on the configuration parameters of the remote interference management reference signal RIM-RS, wherein the configuration parameters are generated based on the method of the first aspect of this disclosure; The second transmitting module 902 is used to transmit the first RIM-RS signal; The first receiving module 903 is used to receive the second RIM-RS signal and determine the orthogonal code of the second RIM-RS signal; The third generation module 904 is used to generate a verification signal based on the orthogonal code and configuration parameters; The second determining module 905 is used to determine the remote interference identity of the second network device relative to the first network device based on the interference type identifier of the time-frequency resource mapping where the second RIM-RS signal is located in the configuration parameters, when the correlation between the second RIM-RS signal and the verification signal is greater than a threshold.

[0187] In one possible implementation of this disclosure, the second generation module 901 is specifically used for: According to the requirements of the configured protocol version, the base sequence of the first RIM-RS signal is generated based on the configured sequence parameters; Based on the orthogonal codes associated with the currently configured first network device, the base sequence is orthogonalized to obtain the orthogonalized sequence.

[0189] The functions and specific implementation principles of the modules described in this embodiment can be found in the above method embodiments, and will not be repeated here.

[0190] In this embodiment, a remote interference detection condition is first detected. Based on the configuration parameters of the Remote Interference Management Reference Signal (RIM-RS), a first RIM-RS signal is generated and transmitted. Then, a second RIM-RS signal is received, and its orthogonal code is determined. Next, a verification signal is generated based on the orthogonal code and configuration parameters. Finally, if the correlation between the second RIM-RS signal and the verification signal is greater than a threshold, the remote interference identity of the second network device relative to the first network device is determined based on the interference type identifier of the time-frequency resource mapping where the second RIM-RS signal is located in the configuration parameters, and the identifier of the second network device associated with the orthogonal code. Thus, by generating and transmitting RIM-RS signals using standardized configuration parameters, and identifying RIM-RS signals transmitted by other network devices, the problem of incompatibility between network devices from different manufacturers due to protocol inconsistencies and parameter incompatibility is solved. This enables inter-vendor inter-vendor network device inter-vendor testing, making it applicable to more scenarios and improving its compatibility and applicability.

[0192] like Figure 10 As shown, the network device mutual detection configuration device 1000 is configured in the second network device and includes: The detection module 1001 is used to detect whether a first RIM-RS signal exists on the corresponding time-frequency resource within the current detection period based on the time-frequency resource configuration in the RIM-RS configuration parameters, wherein the configuration parameters are generated based on the method of the first aspect of this disclosure; The acquisition module 1002 is used to determine the orthogonal code of the first RIM-RS signal when the first RIM-RS signal is present; The fourth generation module 1003 is used to generate a verification signal based on the orthogonal code and configuration parameters; The third determining module 1004 is used to obtain the first network device identifier associated with the orthogonal code and the interference type identifier of the time-frequency resource mapping where the first RIM-RS signal is located from the configuration parameters when the correlation between the first RIM-RS signal and the verification signal is greater than a threshold, and determine the first remote interference identity of the first network device corresponding to the identifier relative to the current second network device. The fifth generation module 1005 is used to generate a second RIM-RS signal based on configuration parameters and return it to the first network device.

[0193] In one possible implementation of this disclosure, the fifth generation module 1005 is specifically used for: Based on the configuration parameters, the base sequence of the second RIM-RS signal is generated, and the base sequence is orthogonalized and scrambled to obtain the scrambled sequence. Based on a preset modulation method, the scrambled sequence is modulated to obtain a modulated signal; Based on the time-frequency resource configuration in the configuration parameters and the status of the near-far detection function, the modulated signal is mapped to the time-frequency resource block corresponding to the second remote interference identity to generate the second RIM-RS signal, wherein the second remote interference identity is the opposite of the first remote interference identity. Send a second RIM-RS signal to the first network device.

[0194] The functions and specific implementation principles of the modules described in this embodiment can be found in the above method embodiments, and will not be repeated here.

[0195] In this embodiment, firstly, based on the time-frequency resource configuration in the RIM-RS configuration parameters, the system detects whether a first RIM-RS signal exists on the corresponding time-frequency resource within the current detection period. If a first RIM-RS signal exists, its orthogonal code is determined. Then, based on the orthogonal code and configuration parameters, a verification signal is generated. If the correlation between the first RIM-RS signal and the verification signal is greater than a threshold, the system obtains the first network device identifier associated with the orthogonal code and the interference type identifier mapped to the time-frequency resource where the first RIM-RS signal is located from the configuration parameters. The system then determines the first remote interference identity of the first network device corresponding to this identifier relative to the current second network device. Finally, based on the configuration parameters, a second RIM-RS signal is generated and returned to the first network device. Thus, when a network device detects a RIM-RS signal sent by another network device, it identifies and detects the signal based on pre-configured standardized and unified configuration parameters to complete interference detection and determine its own interference identity, providing feedback to the corresponding network device. Through unified RIM-RS configuration rules and standardized transmission / reception procedures, the complexity of inter-network device mutual detection is reduced, and the convenience of system deployment and maintenance is improved.
