[0058] Optionally, the core network equipment can be implemented by one or more functional modules in a single device, or by multiple devices working together; this application does not specifically limit this. It is understood that the aforementioned functional modules can be network elements in hardware devices, software functional modules running on dedicated hardware, or virtualized functional modules instantiated on a platform (e.g., a cloud platform).
[0059] Terminals are susceptible to interference from various sources, such as neighboring base stations, uplink and downlink communications from other terminals, and sidelink communications from other terminals. The interference experienced by a terminal can be referred to as interference power or interference-plus-noise (IpN), where IpN is the sum of the interference power and noise power measured by the terminal.
[0060] When a base station is unaware of the interference a terminal experiences on target communication resources, it may configure or schedule communication resources with relatively high interference intensity for the terminal. This may reduce the signal-to-interference-plus-noise ratio (SINR) and consequently impair communication performance, such as increasing the data transmission error rate and latency.
[0061] Interference at a terminal may change rapidly in the time, frequency, and spatial domains. Interference at a terminal is correlated in the time, frequency, and spatial domains. For example, changes in interference in the time domain may be related to interference in the frequency or spatial domains, and future interference may be related to past interference.
[0062] Based on these characteristics of interference, interference prediction can be performed, and the predicted interference information can be used for terminal scheduling. Figure 2 is a schematic diagram of the principle of interference prediction. As shown in Figure 2, the interference prediction module predicts interference based on historically measured interference information to obtain future interference information.
[0063] Knowing future interference information allows the network to make better scheduling decisions and coordinate interference between cells, thereby reducing future interference to terminals and improving link quality. For example, network equipment can avoid scheduling users who will experience strong interference in future communication resources. Furthermore, based on predicted interference information, the network can more accurately determine the modulation and coding scheme (MCS) to reduce the initial block error rate and transmission latency.
[0064] The terminal side knows the interference information on the scheduled future communication resources. By utilizing the correlation of interference in the time domain, frequency domain, or spatial domain, it can better eliminate interference during data demodulation and improve decoding accuracy.
[0065] In this embodiment, interference prediction can be performed on the terminal side or the network side. Figure 3 is a flowchart of interference prediction performed on the terminal side. As shown in Figure 3, the interference prediction process includes the following steps:
[0066] S101. The terminal sends interference prediction-related capability information to the network-side equipment.
[0067] The network-side device can be an access network device or a core network device. The interference prediction-related capability information sent by the terminal to the network-side device may include at least one of the following: the type of interference that the terminal can predict, the time information of the predicted interference, the time information of the historical interference required for prediction, or the prediction time interval.
[0068] The type of interference that the terminal can predict is, for example, interference power or IpN. The timing information of the predicted interference indicates how far in the future the terminal can predict interference. The timing information of the historical interference required for prediction indicates how long past interference information should be used for interference prediction. Interference prediction is usually not continuous; the prediction time interval indicates how often the terminal performs interference prediction.
[0069] S102. The network-side equipment sends interference measurement configuration information and interference reporting configuration information to the terminal.
[0070] After receiving the interference prediction capability information from the terminal, the network-side device determines the interference prediction configuration information based on the interference prediction capability information. The interference prediction configuration information includes interference measurement configuration information and interference reporting configuration information.
[0071] Interference measurement configuration information is used to configure interference measurement resources for the terminal. Interference measurement resources refer to the communication resources configured by the network-side equipment for the terminal to measure interference. The terminal measures interference through the interference measurement resources.
[0072] For example, interference measurement resources may include channel state information reference signal (CSI-RS), channel state information for interference measurement (CSI-IM), interference measurement resource (IMR), or DMRS.
[0073] A CSI-RS refers to a reference signal transmitted by the base station, which the terminal can use to estimate the channel and feed back channel state information to the base station. A CSI-IM refers to a set of resource elements (REs) reserved for interference measurement. An IMR is a time-frequency resource allocated by the network to the terminal for interference measurement.
[0074] Interference reporting configuration information is used to configure interference reporting related information for the terminal. Interference reporting related information may include the content of the reported interference information, the time of interference reporting, and the interference measurement resources on which the reported interference information is obtained.
[0075] S103. The terminal performs interference measurement based on the interference measurement configuration information to obtain interference measurement information.
[0076] The terminal measures interference based on the interference measurement resources configured by the network-side equipment, and obtains interference measurement information (i.e., interference measurement results). This interference measurement information may include a set of measured interference values, or a set of measured interference values and evaluation indicators for those measured interference values.
[0077] A set of measurement interference values includes one or more measurement interference values. When a set of measurement interference values includes multiple measurement interference values, these multiple measurement interference values can be measurement interference values at different time points of the same interference measurement resource. Optionally, the same time point can also include multiple measurement interference values.
[0078] Optionally, the measured interference values include, but are not limited to: interference power, SINR, interference level, carrier-to-interference ratio (C / I), etc., measured in a certain time domain, frequency domain, or spatial domain.
[0079] Interference level is an indicator describing the intensity of interference. In one example, the interference level can be divided into three levels: high, medium, and low, which can be indicated by 2 bits. In another example, the interference level can be divided into ten levels from 1 to 10, with higher values indicating stronger interference. Each level can be associated with a range of interference power or SINR, depending on the device implementation or protocol.
[0080] Optionally, the evaluation metrics for measuring interference values include at least one of the following: probability of measuring interference values, confidence level, accuracy, uncertainty, and uncertainty range.
[0081] The probability of measuring interference values represents the probability that a terminal will measure a specific interference value on interference measurement resources. A higher value for the evaluation index of measuring interference values indicates a higher probability of occurrence, greater confidence or credibility, higher accuracy, lower uncertainty, or a smaller range of uncertainty.
[0082] Optionally, the interference measurement information may be obtained based on a set of interference measurement resources, which may include: one or more CSI-RS, one or more CSI-IM, or one or more IMR.
[0083] S104. The terminal performs interference prediction based on interference measurement information.
[0084] The terminal uses an interference prediction algorithm to predict interference based on the interference measurement information, and obtains interference prediction information. The interference measurement information is historical interference information, and the interference prediction information is the predicted future interference information.
[0085] The interference prediction information may include a set of predicted interference values, or a set of predicted interference values and an evaluation index for those predicted interference values.
[0086] Optionally, a set of predicted interference values may include one or more predicted interference values. When a set of predicted interference values includes multiple predicted interference values, these multiple predicted interference values may be predicted interference values at different time points of the same communication resource. Optionally, the same time point may also include multiple predicted interference values.
[0087] Optionally, the predicted interference values include, but are not limited to: interference power, SINR, interference level, carrier-to-interference ratio (C / I), etc., predicted in a certain time domain, frequency domain, or spatial domain.
[0088] Optionally, the evaluation metrics for predicting interference values include at least one of the following: probability of predicting interference values, confidence level, accuracy, uncertainty, and uncertainty range.
[0089] The probability of predicting interference values represents the probability that a terminal will predict a specific interference value on communication resources. A higher value for the evaluation index of predicted interference values indicates a higher probability of occurrence, greater confidence or credibility, higher accuracy, lower uncertainty, or a smaller range of uncertainty.
[0090] S105. The terminal sends interference prediction information to the network-side equipment.
[0091] The terminal reports interference prediction information based on the interference reporting configuration information configured by the network-side equipment. Optionally, the terminal carries this interference prediction information through a Channel State Feedback (CSF) report. This CSF report may include interference prediction information for specific time, frequency, or spatial resources.
[0092] Optionally, the terminal performs interference measurement on the first communication resource (i.e., interference measurement resource), and predicts the interference information of the terminal on the second communication resource based on the interference measurement information on the first communication resource. The first communication resource and the second communication resource may be the same, partially the same or different, and this application embodiment does not limit this.
[0093] The first and second communication resources here can be regarded as a collection of one or more time-domain resources, frequency-domain resources and spatial-domain resources, and may also be associated with at least one reference signal resource, at least one set of reference signal resources or at least one reference signal configuration.
[0094] S106. The network-side device sends scheduling information to the terminal.
[0095] After receiving interference prediction information obtained from the terminal, network-side equipment (such as the serving base station or neighboring base stations of the terminal) determines the terminal's scheduling information based on the interference prediction information. For example, the base station can avoid scheduling terminals that are predicted to experience strong interference on future communication resources. Furthermore, based on the interference prediction information, the base station can more accurately determine the MCS (Multi-Segment Control), thereby reducing the initial block error rate and transmission latency.
[0096] Figure 4 is a flowchart of interference prediction performed by network-side devices. As shown in Figure 4, the interference prediction process includes the following steps:
[0097] S201. The terminal sends interference prediction capability information to the network-side equipment.
[0098] S202. The network-side equipment sends interference measurement configuration information and interference reporting configuration information to the terminal.
[0099] S203. The terminal performs interference measurement based on the interference measurement configuration information to obtain interference measurement information.
[0100] The specific implementation of steps S201-S203 is the same as that of steps S101-S103 mentioned above, and will not be repeated here.
[0101] S204. The terminal sends interference measurement information to the network-side equipment.
[0102] The terminal reports interference measurement information according to the interference reporting configuration information configured on the network-side equipment. Optionally, the terminal carries this interference measurement information through a CSF report. This CSF report may include interference measurement information on specific time, frequency, or airspace resources.
[0103] S205. Network-side equipment performs interference prediction based on interference measurement information.
[0104] Based on the interference measurement information reported by the terminal, the network-side equipment uses an interference prediction algorithm to predict interference and obtain interference prediction information. This interference prediction information may include a set of predicted interference values, or a set of predicted interference values and an evaluation index for those predicted interference values.
[0105] S206. The network-side device sends scheduling information to the terminal.
[0106] Network-side devices determine terminal scheduling information based on interference prediction information they obtain, in order to make better scheduling decisions.
[0107] In the interference prediction process shown in Figures 3 and 4, in order for network-side devices to consider the temporal, frequency, and spatial characteristics of interference experienced by the terminal during resource scheduling, the terminal needs to report interference-related information to the network side. This interference-related information includes the aforementioned interference measurement information or interference prediction information.
[0108] In this embodiment, the interference-related information reported by the terminal may be in the form of a distribution-based representation or a non-distribution-based representation. Specifically, for a distribution-based representation, the interference distribution reported by the terminal may be a probability density function or a probability mass function related to the time domain, frequency domain, or spatial domain.
[0109] A probability density function describes the probability of a continuous random variable within a certain range. A probability mass function describes the probability of a discrete random variable equaling certain values. For example, X is a discrete random variable, and its possible range of values is: R X ={x1,x2,x3,x4,…}, the probability mass function of X is: P X (x k ) = P(X = x k ), k = 1, 2, 3, 4, ...
[0110] In some implementations, the interference distribution reported by the terminal takes the form of a probability quality function, which describes the interference value measured or predicted on a certain time domain, frequency domain, or spatial domain resource and its probability, i.e.: P X (IpN=x) k|t=t m f = f n ,s=s q )
[0111] Where k = 1, 2, 3, 4, ..., m = 1, 2, 3, 4, ..., n = 1, 2, 3, 4, ..., q = 1, 2, 3, 4, ...
[0112] x k This represents the k-th interference value, such as x1 = -30dBm, x2 = -31dBm, x3 = -32dBm, etc.
[0113] t m This represents the m-th time-domain resource, such as t1 = slot1, t2 = slot2, t3 = slot3, etc.
[0114] f n This represents the nth frequency domain resource, such as f1 = subband1, f2 = subband2, f3 = subband3, etc.
[0115] s q This represents the q-th spatial resource, such as s1 = beamindex1, s2 = beamindex2, s3 = beamindex3, etc.
[0116] P X (IpN=x) k |t=t m f = f n ,s=s q ) indicates that the terminal has time-domain resources t m Frequency domain resources f n and airspace resources q The measured or predicted interference value is x k The probability of.
[0117] It is understandable that the granularity of time-domain resources, frequency-domain resources, and spatial-domain resources is not limited to the slots, subbands, or beams mentioned above. They can also be other things. For example, time-domain resources can also be Orthogonal Frequency Division Multiplexing (OFDM) symbols, subframes, frames, etc., frequency-domain resources can also be physical resource blocks (PRBs) or resource blocks (RBs), and spatial-domain resources can also be physical cells, reference signal resources, ports, etc.
[0118] Optionally, in some implementations, the network-side device may be configured with the granularity of interference measurement or interference prediction: frequency domain granularity, time domain granularity, or spatial domain granularity.
[0119] Frequency domain granularity: Interference measurement or interference prediction is based on the full bandwidth or sub-band (or multiple sub-bands), etc. If an interference value can be associated with the full bandwidth or (one or more) sub-bands, then this interference value describes the interference intensity of the full bandwidth or (one or more) sub-bands.
[0120] Temporal granularity: Interference measurement or interference prediction is symbol-level interference, slot-level interference, or multiple slot-level interference, etc. For example, if an interference value is slot-level interference, then this interference value describes the interference intensity on one slot.
[0121] Spatial granularity: Network-side devices may configure multiple reference signal resources or beams for interference measurement or interference prediction. If an interference value is associated with a specific beam or reference signal resource, then the interference value describes the interference intensity on that beam or reference signal resource.
[0122] Optionally, in some implementations, network-side devices or terminals use artificial intelligence (AI) models to predict interference. The AI model used for interference prediction is also called an AI interference prediction model.

[0127] The interference prediction method provided in this application will be described in detail below with reference to the accompanying drawings, through some embodiments and application scenarios.
[0128] Figure 5 is a flowchart of an interference prediction method provided in an embodiment of this application. The method in this embodiment is executed by a terminal. As shown in Figure 5, the method provided in this embodiment includes the following steps.
[0129] S301, The terminal receives the first auxiliary information from the network-side device.
[0130] The terminal receives first auxiliary information sent by the network-side device. The first auxiliary information is used to assist the terminal in interference prediction. The first auxiliary information includes information about at least one cell, network environment information, or communication environment information.
[0131] For example, the first auxiliary information includes at least one of the following:
[0132] (1) At least one cell’s first scheduling algorithm information or scheduling algorithm update information.
[0133] Cell scheduling algorithms are used to allocate cell communication resources among different terminals. Commonly used scheduling algorithms include proportional fair scheduling and round-robin scheduling.
[0134] (2) At least one cell’s first beam information or updated beam information.
[0135] The beam information of a cell can include the number of beams, beamwidth, beam center angle, etc.
[0136] (3) At least one cell’s first frequency domain scheduling granularity information or frequency domain scheduling granularity information update information.
[0137] The frequency domain scheduling granularity of a cell can include broadband scheduling, subband scheduling, etc.
[0138] (4) At least one cell’s first scheduling type or scheduling type update information.
[0139] The scheduling type of a cell can include semi-persistent scheduling, dynamic scheduling, or static scheduling.
[0140] (5) At least one cell’s first network load information or network load information update information.
[0141] The network load information of a community is used to describe the network's operating status. Network load is closely related to network performance; for example, network load is divided into three levels: high, medium, and low. Typically, when the network load is high, the utilization rate of time-frequency resources may be higher.
[0142] (6) At least one cell’s first slot format information or slot format information update information.
[0143] The slot format refers to the configuration method of slots in the network. It defines the transmission direction of each slot within a subframe, including which slots are uplink slots, which slots are downlink slots, and which slots are flexible slots. Uplink slots are used for uplink transmission, downlink slots are used for downlink transmission, and flexible slots can be used for both uplink and downlink transmission.
[0144] (7) At least one cell’s first transmit power information or transmit power information update information.
[0145] The cell's transmit power, also known as the cell's maximum transmit power, refers to the maximum sum of the downlink transmit power of all channels that can be transmitted simultaneously within the cell. Configuring the cell's transmit power is crucial for ensuring communication quality, improving spectrum utilization, and optimizing network performance. In NR systems, the cell's transmit power can be flexibly configured.
[0146] (8) At least one cell’s first service type information or service type information update information.
[0147] The service types in a cell can include periodic services and non-periodic services. Periodic services refer to service data packets arriving at a certain period, such as one data packet arriving every 10 milliseconds. The size of the data packets can be fixed or variable.
[0148] (9) At least one cell’s first ID or ID update information.
[0149] At least one cell (i.e., one or more) in the first auxiliary information may include the terminal's serving cell and / or neighboring cells (one or more neighboring cells).
[0150] The first auxiliary information is information configured by the network-side device for the terminal to assist in interference prediction in the current or future period. This first auxiliary information may be the same as or different from the first auxiliary information used by the terminal in the previous period. If the first auxiliary information is different from the first auxiliary information used by the terminal in the previous period, that is, at least one piece of information in the first auxiliary information has changed.
[0151] When the first auxiliary information differs from the first auxiliary information used by the terminal in a previous period, the network-side device can indicate the changed first auxiliary information to the terminal in the following two ways:
[0152] Method 1: The first auxiliary information includes the values of each piece of information after the changes.
[0153] Method 2: The first auxiliary information includes update information for each piece of information. This update information is used to indicate whether the information should be updated. This update information can also be a change indication information, which is used to indicate whether the information has changed. The information that has changed is the information that needs to be updated.
[0154] Of the nine types of information mentioned above, some or all may have changed. For Method 1, the first auxiliary information may include the values of all information, or it may only include the values of the changed information. Similarly, for Method 2, the first auxiliary information may include updated information for all information, or it may only include updated information for the changed information.
[0155] In Method 1, after receiving the first auxiliary information, the terminal compares the previous values of each piece of information with the values included in the first auxiliary information. For a given piece of information, if the previous value of that information is the same as the value included in the first auxiliary information, the terminal determines that the information has not changed; if the previous value of that information is different from the value included in the first auxiliary information, the terminal determines that the information has changed. Taking frequency domain scheduling granularity information as an example, if the previous value of the frequency domain scheduling granularity information is broadband scheduling, and the value included in the first auxiliary information is sub-band scheduling, then the terminal determines that the frequency domain scheduling granularity information has changed.
[0156] In Method 2, the terminal determines whether the information has changed based on the update information of each piece of information. For example, the update information is indicated by a bit. When the value of the update information is 1, it means that the information has changed, and when the value of the update information is 0, it means that the information has not changed.
[0157] In one implementation, the update information may only be used to indicate whether information should be updated. When the update information indicates that information should be updated, it means that the information has changed; when the update information indicates that information should not be updated, it means that the information has not changed. In another implementation, the update information may include update indication information and the updated value. The update indication information is used to indicate whether information should be updated. If information needs to be updated, the update information may also include the updated value of that information.
[0158] Optionally, in this embodiment, the terminal uses an AI interference prediction model to predict interference. Accordingly, the first auxiliary information is associated with at least one AI interference prediction model. The first auxiliary information is information configured by the network-side device for the terminal for the current or future period. The first auxiliary information associated with the AI interference prediction model, or the first auxiliary information used during model training or model data collection, may be the same or different.
[0159] The first auxiliary information is different from the first auxiliary information associated with the AI interference prediction model or used during model training or model data collection. That is, at least one of the first auxiliary information has changed. The network-side device can indicate the changed first auxiliary information to the terminal in the above two ways, which will not be repeated here.
[0160] In some implementations, before receiving the first auxiliary information from the network-side device, the terminal sends a first request message to the network-side device, which is used to request the first auxiliary information from the network-side device.
[0161] In one example, the first request message includes the types of various first auxiliary information requested from the network-side device, that is, the terminal tells the network-side device which first auxiliary information is needed, and the network-side device returns the values of various first auxiliary information to the terminal.
[0162] In another example, the first request message includes first configuration information, which is used to indicate the interference prediction function supported by the terminal, that is, the terminal tells the network-side device the values of various first auxiliary information it already has.
[0163] In some implementations, the terminal sends the first configuration information to the network-side device before receiving the first auxiliary information from the network-side device.
[0164] In some implementations, the network-side device decides to send the first auxiliary information to the terminal based on its own implementation. For example, the network-side device sends the first auxiliary information to the terminal periodically, or the network-side device sends the first auxiliary information to the terminal when it determines that the first auxiliary information has changed.
[0165] For example, the first configuration information includes at least one of the following:
[0166] (1) At least one timestamp information is provided to indicate the time when the AI interference prediction model was acquired or the time when the dataset was acquired.
[0167] (2) At least one time period information, used to indicate the acquisition time of the AI interference prediction model or the acquisition time of the dataset.
[0168] Optionally, the first configuration information is associated with at least one AI interference prediction model of the terminal, which is used to predict interference. When the first configuration information is associated with at least one AI interference prediction model of the terminal, the terminal indicates the acquisition time of the AI interference prediction model or the acquisition time of the dataset by carrying the timestamp information or time period information.
[0169] The acquisition time of the AI interference prediction model can be either the training time or the update time of the AI interference prediction model. The dataset refers to the dataset used during the training or update of the AI interference prediction model, and the acquisition time of the dataset refers to the actual time when the data in the dataset was generated. Based on the acquisition time of the AI interference prediction model or the acquisition time of the dataset, the network-side device can obtain the first auxiliary information associated with the AI interference prediction model, or the first auxiliary information expected by the terminal. For example, if the network-side device stores network configuration log information at that time, the first auxiliary information at that time can be obtained by consulting the log information at that time.
[0170] The first auxiliary information used by the AI interference prediction model during training and inference may be the same or different. Inconsistency in the first auxiliary information used by the AI interference prediction model during training and inference may affect the inference performance of the AI interference prediction model. In this embodiment, the network-side device configures the first auxiliary information for the terminal as consistent as possible with the first auxiliary information used during training based on the first configuration information reported by the terminal, so as to improve the accuracy of the prediction results of the AI interference prediction model.
[0171] In one scenario, the network-side device can configure the first auxiliary information adapted to the AI interference prediction model for the terminal based on the acquisition time of the AI interference prediction model or the acquisition time of the dataset reported by the terminal.
[0172] In another scenario, the network-side device determines whether the terminal's AI interference prediction model is available or whether it is activated based on the acquisition time of the AI interference prediction model or the acquisition time of the dataset reported by the terminal.
[0173] (3) At least one cell’s second scheduling algorithm information.
[0174] (4) Second beam information of at least one cell.
[0175] (5) Second frequency domain scheduling granularity information of at least one cell.
[0176] (6) At least one cell’s second scheduling type.
[0177] (7) Second network load information of at least one cell.
[0178] (8) Second time slot format information of at least one cell.
[0179] (9) Second transmission power information of at least one cell.
[0180] (10) At least one second service type in a cell.
[0181] (11) At least one second identifier of a cell.
[0182] After receiving the first configuration information, the network-side device determines the first auxiliary information based on the first configuration information. When the first configuration information is associated with at least one AI interference prediction model of the terminal, the first auxiliary information determined by the network-side device is also associated with that at least one AI interference prediction model.
[0183] For any piece of information in the first auxiliary information, the second information in the first configuration information may be the same as or different from the first information in the first auxiliary information. The second information is the information used by the terminal for interference prediction before the current moment, while the first information is the information newly determined by the network-side device for the terminal for future interference prediction. Taking scheduling algorithm information as an example, the first scheduling algorithm information and the second scheduling algorithm information may be the same or different. Other information is the same, and so on, without further listing.
[0184] Optionally, the first configuration information may also include the reference signal type or first indication information supported by the terminal when performing interference measurement or interference prediction. The first indication information is used to indicate whether the terminal supports the demodulation reference signal (DMRS) type when performing interference measurement or interference prediction.
[0185] The network-side device determines the target reference signal type used by the terminal to perform interference measurement or interference prediction based on the reference signal type or first indication information supported by the terminal when performing interference measurement or interference prediction. The terminal can measure interference information based on the target reference signal type and predict future interference information based on the measured interference information.
[0186] Optionally, the reference signal types supported by the terminal when performing interference measurement or interference prediction include at least one of the following: CSI-RS for channel measurement, CS-RS for interference measurement, CSI-IM and DMRS; or DMRS and non-DMRS; or CSI-RS and DMRS.
[0187] S302, The terminal performs interference prediction based on the first auxiliary information.
[0188] Optionally, the terminal uses an AI interference prediction model for interference prediction. Of course, the terminal can also use other interference prediction algorithms. The terminal determines the interference prediction algorithm to use based on the first auxiliary information. It is understood that different first auxiliary information corresponds to different network environments in the cell, and the interference prediction algorithm used should be adapted to the cell's network environment. Therefore, the interference prediction algorithm can be determined based on the first auxiliary information. Different first auxiliary information may correspond to different interference prediction algorithms, and using an adapted interference prediction algorithm will yield more accurate interference prediction information.
[0189] When a terminal uses an AI interference prediction model for interference prediction, in some implementations, the terminal determines the AI interference prediction model to be used based on first auxiliary information, and then uses the determined AI interference prediction model for interference prediction. When the first auxiliary information is associated with multiple AI interference prediction models, the terminal can select a target AI interference prediction model from the multiple AI interference prediction models based on the first auxiliary information for interference prediction.
[0190] For example, the terminal compares the first auxiliary information sent by the network-side device with its own local first configuration information. When some information in the first auxiliary information is updated or changed, the terminal determines that the AI interference prediction model used previously or currently is no longer applicable to the future network environment. The terminal can then reselect an appropriate AI interference prediction model for interference prediction based on the first auxiliary information sent by the network-side device.
[0191] In some implementations, before the terminal performs interference prediction based on the first auxiliary information, the method further includes: the terminal receiving second indication information from a network-side device regarding the first auxiliary information. This second indication information is used to indicate information related to the first auxiliary information, and includes at least one of the following:
[0192] Time indication information is used to indicate the effective time of the first auxiliary information;
[0193] Frequency indication information, used to indicate the carrier frequency associated with the first auxiliary information;
[0194] Bandwidth indication information, used to indicate the bandwidth associated with the first auxiliary information;
[0195] At least one Bandwidth Part (BWP) ID, wherein the frequency range of the BWP corresponding to the at least one BWP identifier is the effective frequency range of the first auxiliary information.
[0196] Interference often changes rapidly, and network-side devices often dynamically adjust scheduling strategies based on network conditions. Therefore, network-side devices need to indicate the validity period of the first auxiliary information. Within the validity period (or validity time range) of the first auxiliary information indicated by the network-side device, the terminal can assume that the first auxiliary information is valid or that the first auxiliary information remains unchanged.
[0197] Optionally, the effective time range of the first auxiliary information can be indicated in the following ways:
[0198] Method 1: The network-side device indicates the start and end times of the valid time range.
[0199] Method 2: The network-side device indicates the start time of the valid time range and a time range (i.e., a period of time). The terminal can obtain the end time of the valid time range based on the start time and the time range.
[0200] Method 3: The network-side device indicates the end time of the valid time range, and the method for determining the start time of the valid time range is agreed upon by the protocol, such as agreeing that the start time is the time when the terminal receives the first auxiliary information.
[0201] Method four: The network-side device specifies a time range. The start time of the valid time range is determined by a protocol, such as specifying the start time as the time the terminal receives the first auxiliary information. The terminal can then determine the end time of the valid time range based on the specified start time and the time range itself.
[0202] The frequency indication information is used to indicate on which carrier frequencies the first auxiliary information is valid. The frequency indication information may include the frequency information of each carrier associated with the first auxiliary information. The frequency information may be the frequency point of the carrier or the frequency range of the carrier.
[0203] The bandwidth indication information is used to indicate the bandwidth on which the first auxiliary information is valid. The bandwidth indication information may include the frequency range of the bandwidth associated with the first auxiliary information, for example, the bandwidth associated with the first auxiliary information is 15 MHz, 30 MHz, or 60 MHz.
[0204] The at least one BWP ID is used to indicate the valid frequency range of the first auxiliary information, which can also be understood as indicating that the first auxiliary information is valid on the specific BWP corresponding to the BPW identifier. Each BWP ID corresponds to one BWP, and each BWP corresponds to one frequency range.
[0205] In some implementations, the terminal receives a third or fourth indication from the network-side device. The third indication is used to indicate whether the AI interference prediction model is activated or deactivated, and the fourth indication is used to indicate whether the AI interference prediction model is available.
[0206] In some implementations, the network-side device can determine whether to activate the AI interference prediction model or whether the AI interference prediction model is available based on the first configuration information, and send a third or fourth indication information to the terminal. The first configuration information is used to indicate the interference prediction function supported by the terminal.
[0207] In some implementations, the third indication information is indicated by 1 bit, where bit 1 indicates activation of the AI interference prediction model and bit 0 indicates deactivation of the AI interference prediction model; or, bit 1 indicates switching the state of the AI interference prediction model, switching to deactivation if the original state of the AI interference prediction model was activation, and switching to activation if the original state of the AI interference prediction model was deactivation, and bit 0 indicates not switching the state of the AI interference prediction model.
[0208] In some implementations, the fourth indication information is indicated by 1 bit, where bit 1 indicates that the AI interference prediction model is available and bit 0 indicates that the AI interference prediction model is unavailable; or, bit 1 indicates switching the state of the AI interference prediction model, switching to the unavailable state if the original state of the AI interference prediction model was available, and switching to the available state if the original state of the AI interference prediction model was unavailable, and bit 0 indicates not switching the state of the AI interference prediction model.
[0209] In some implementations, the terminal receives a fifth indication information from the network-side device, which is used to indicate the effective time of the AI interference prediction model.
[0210] Within the effective time (or effective time range) of the AI interference prediction model indicated by the network-side device, the terminal can assume that the AI interference prediction model is effective, activatable, or available.
[0211] In some implementations, the network-side device indicates the effective time range of an AI interference prediction model. The indication method for the effective time range of the AI interference prediction model can be any of the indication methods for the effective time range of the first auxiliary information mentioned above, which will not be repeated here.
[0212] In some implementations, the network-side device instructs the terminal to use a fifth instruction message to set a timer, which then deactivates the AI interference prediction model after the timer expires.
[0213] In some implementations, the terminal receives at least one of the following information from the network-side device: interference measurement configuration information or interference reporting configuration information. Based on the interference measurement configuration information, the terminal performs interference measurement using the corresponding interference measurement resources to obtain interference measurement information. Based on this interference measurement information and the AI interference prediction model, it obtains interference prediction information and sends the interference prediction information to the network-side device according to the interference reporting configuration information. In this implementation, the terminal performs interference prediction. The AI interference prediction model is determined based on the first auxiliary information. The interference measurement configuration information, interference reporting configuration information, interference measurement process, and interference reporting content refer to the relevant content of the interference prediction process shown in Figures 2 and 3 above, and will not be repeated here.
[0214] The network-side device determines the terminal's scheduling information based on the interference prediction information reported by the terminal. The terminal receives the scheduling information sent by the network-side device. The scheduling information includes at least one of the following: time-domain resources of the Physical Downlink Shared Channel (PDSCH), frequency-domain resources of the PDSCH, or modulation and coding scheme (MCS).
[0215] Modulation Coding Scheme (MCS) is a key parameter in wireless communication, defining the modulation and coding scheme for data transmission. The choice of MCS directly affects data transmission rate, reliability, and spectral efficiency. Network-side equipment selects a matching MCS based on interference prediction information from the terminal. For example, when the terminal's interference prediction information indicates severe future interference, the network-side equipment can choose a low-order modulation scheme and higher coding redundancy (i.e., a lower MCS) to ensure data transmission reliability. Conversely, when the terminal's interference prediction information indicates less severe future interference (i.e., favorable future channel conditions), the network-side equipment can choose a high-order modulation scheme and lower coding redundancy (i.e., a higher MCS) to improve data transmission rate.
[0216] In some implementations, the terminal receives at least one of the following information from the network-side device: interference measurement configuration information or interference reporting configuration information. Based on the interference measurement configuration information, the terminal performs interference measurement using the corresponding interference measurement resources to obtain interference measurement information, and then sends this interference measurement information to the network-side device according to the interference reporting configuration information. In this implementation, the network-side device performs interference prediction based on the interference measurement information reported by the terminal and determines scheduling information based on the interference prediction information.
[0217] In this embodiment, the terminal receives first auxiliary information from the network-side device and performs interference prediction based on the first auxiliary information. The accuracy of interference prediction is improved by the terminal performing interference prediction based on the first auxiliary information, and the network-side device can make better scheduling decisions based on the accurate interference prediction information.
[0218] Figure 6 is a flowchart of an interference prediction method provided in an embodiment of this application. The method in this embodiment is executed by a network-side device. As shown in Figure 6, the method provided in this embodiment includes the following steps.
[0219] S401. The network-side device sends first auxiliary information to the terminal. The first auxiliary information is used by the terminal to predict interference.
[0220] The first auxiliary information is used to assist the terminal in interference prediction. The first auxiliary information includes information about at least one cell, network environment information, or communication environment information. The at least one cell includes the terminal's serving cell and / or neighboring cells.
[0221] For example, the first auxiliary information includes at least one of the following:
[0222] (1) At least one cell's first scheduling algorithm information or scheduling algorithm update information;
[0223] (2) First beam information or updated beam information of at least one cell;
[0224] (3) At least one cell's first frequency domain scheduling granularity information or frequency domain scheduling granularity information update information;
[0225] (4) At least one cell’s first scheduling type or scheduling type update information;
[0226] (5) At least one cell's first network load information or updated network load information;
[0227] (6) At least one cell's first time slot format information or time slot format information update information;
[0228] (7) At least one cell’s first transmit power information or transmit power information update information;
[0229] (8) At least one cell's first service type information or updated service type information;
[0230] (9) At least one cell’s first identifier or identifier update information.
[0231] The first auxiliary information is the auxiliary information configured by the network-side device for the terminal to assist the terminal in interference prediction in the current or future period of time. The first auxiliary information may be the same as or different from the first auxiliary information used by the terminal in the previous period of time.
[0232] When the first auxiliary information differs from the first auxiliary information used by the terminal in a previous period, the network-side device can indicate the changed first auxiliary information to the terminal in the following two ways:
[0233] Method 1: The first auxiliary information includes the values of each piece of information after the changes.
[0234] Method 2: The first auxiliary information includes update information for each piece of information, which is used to indicate whether the information should be updated.
[0235] Optionally, in this embodiment, the terminal uses an AI interference prediction model to predict interference. Accordingly, the first auxiliary information is associated with at least one AI interference prediction model. The first auxiliary information is auxiliary information configured by the network-side device for the terminal to use for interference prediction in the current or future period. The first auxiliary information associated with the AI interference prediction model, or the first auxiliary information used during model training or model data collection, may be the same or different.
[0236] The first auxiliary information is different from the first auxiliary information associated with the AI interference prediction model or used during model training or model data collection. That is, at least one of the first auxiliary information has changed. The network-side device can indicate the changed first auxiliary information to the terminal in the above two ways, which will not be repeated here.
[0237] In some implementations, before the network-side device sends the first auxiliary information to the terminal, the network-side device receives a first request message sent by the terminal, which is used to request the first auxiliary information.
[0238] In one example, the first request message includes the type of first auxiliary information requested from the network-side device, that is, the terminal tells the network-side device what first auxiliary information is needed, and the network-side device returns the values of various first auxiliary information to the terminal.
[0239] In another example, the first request message includes first configuration information, which is used to indicate the interference prediction function supported by the terminal, that is, the terminal tells the network-side device the values of various first auxiliary information it already has.
[0240] In some implementations, before the network-side device sends the first auxiliary information to the terminal, the network-side device receives the first configuration information sent by the terminal. The first configuration information is used to indicate the interference prediction function supported by the terminal, and the network-side device determines the first auxiliary information based on the first configuration information.
[0241] In some implementations, the network-side device decides to send the first auxiliary information to the terminal based on its own implementation. For example, the network-side device sends the first auxiliary information to the terminal periodically, or the network-side device sends the first auxiliary information to the terminal when it determines that the first auxiliary information has changed.
[0242] For example, the first configuration information includes at least one of the following:
[0243] (1) At least one timestamp information is provided to indicate the time when the AI interference prediction model was acquired or the time when the dataset was acquired.
[0244] (2) At least one time period information, used to indicate the acquisition time of the AI interference prediction model or the acquisition time of the dataset.
[0245] (3) At least one cell’s second scheduling algorithm information.
[0246] (4) Second beam information of at least one cell.
[0247] (5) Second frequency domain scheduling granularity information of at least one cell.
[0248] (6) At least one cell’s second scheduling type.
[0249] (7) Second network load information of at least one cell.
[0250] (8) Second time slot format information of at least one cell.
[0251] (9) Second transmission power information of at least one cell.
[0252] (10) At least one second service type in a cell.
[0253] (11) At least one second identifier of a cell.
[0254] The first auxiliary information used by the AI interference prediction model during training and inference may be the same or different. Inconsistency in the first auxiliary information used during training and inference may affect the inference performance of the AI interference prediction model. In this embodiment, the network-side device can obtain the first auxiliary information associated with the AI interference prediction model, or the first auxiliary information expected by the terminal, based on the acquisition time of the AI interference prediction model or the acquisition time of the dataset reported by the terminal. Based on the acquisition time of the AI interference prediction model or the acquisition time of the dataset, the network-side device can configure the first auxiliary information adapted to the AI interference prediction model for the terminal, thereby improving the accuracy of the prediction results of the AI interference prediction model.
[0255] In some implementations, the first configuration information is associated with at least one AI interference prediction model supported by the terminal device. The AI interference prediction model is used to perform interference prediction. Correspondingly, the first auxiliary information is associated with at least one AI interference prediction model supported by the terminal device.
[0256] In some implementations, the first configuration information also includes the reference signal type or first indication information supported by the terminal when performing interference measurement or interference prediction. The first indication information is used to indicate whether the terminal supports the DMRS type when performing interference measurement or interference prediction.
[0257] Optionally, the reference signal types supported by the terminal when performing interference measurement or interference prediction include at least one of the following: CSI-RS for channel measurement, CS-RS for interference measurement, CSI-IM and DMRS; or DMRS and non-DMRS; or CSI-RS and DMRS.
[0258] In some implementations, the network-side device determines the interference measurement resources for the terminal based on the reference signal type or first indication information supported by the terminal when performing interference prediction. That is, it determines the target reference signal type used by the interference measurement resources. The network-side device sends the interference measurement resources to the terminal, and the terminal can measure the interference information based on the interference measurement resources corresponding to the target reference signal type.
[0259] Optionally, in some implementations, when the reference signal types supported by the terminal during interference measurement or interference prediction include the DMRS type, or when the first indication information indicates that the terminal supports the DMRS type during measurement or interference prediction, the network-side device prioritizes configuring DMRS resources for the terminal as interference measurement resources. Interference measurement based on the CSI-RI type incurs higher overhead, while interference measurement based on the DMRS type incurs lower overhead. The network-side device determines whether it is necessary to configure CSI-RS for the terminal's interference prediction based on the reference signal types supported by the terminal during interference measurement or interference prediction, or the first indication information. If configuring CSI-RS is not necessary, DMRS can be prioritized for the terminal's interference prediction to save interference measurement overhead.
[0260] In some implementations, the network-side device further sends second indication information of the first auxiliary information to the terminal. This second indication information is used to indicate information related to the first auxiliary information, and includes at least one of the following:
[0261] Time indication information is used to indicate the effective time of the first auxiliary information;
[0262] Frequency indication information, used to indicate the carrier frequency associated with the first auxiliary information;

[0264] At least one BWP ID, wherein the frequency range of the BWP corresponding to the at least one BWP ID is the effective frequency range of the first auxiliary information.
[0265] In some implementations, the network-side device sends a third or fourth indication to the terminal. The third indication indicates whether the AI interference prediction model is activated or deactivated, and the fourth indication indicates whether the AI interference prediction model is available. The terminal activates or deactivates the AI interference prediction model based on the third indication. After activation, the terminal can use the AI interference prediction model to predict interference. Alternatively, the terminal determines whether the AI interference prediction model is available or unavailable based on the fourth indication. If the AI interference prediction model is available, the terminal can use it to predict interference.
[0266] In some implementations, the network-side device receives first configuration information sent by the terminal, and determines whether to activate or deactivate the AI interference prediction model, or whether the AI interference prediction model is available or unavailable, based on the first configuration information. The first configuration information is used to indicate the interference prediction functions supported by the terminal.
[0267] For example, if the first auxiliary information used by the AI interference prediction model at the time of acquisition of the AI interference prediction model or the time of acquisition of the dataset is different from the first auxiliary information at the current time or a future period, it indicates that the network environment has changed and the AI interference prediction model may no longer be applicable. In this case, the network-side device can choose to deactivate the AI interference prediction model or determine that the AI interference prediction model is unavailable.
[0268] For example, if the network load information carried in the first configuration information is different from the network load information at the current time or in the future, then the AI interference prediction model may no longer be applicable. The network-side device can choose to deactivate the AI interference prediction model or determine that the AI interference prediction model is unavailable.
[0269] In some implementations, the network-side device sends a fifth indication message to the terminal, which indicates the effective time of the AI interference prediction model, which is used to perform interference prediction.

In this implementation, the terminal performs the interference prediction.
[0272] In some implementations, the network-side device sends at least one of the following information to the terminal: interference measurement configuration information or interference reporting configuration information; the network-side device receives interference measurement information from the terminal, which is measured by the terminal according to the interference measurement configuration information; the network-side device performs interference prediction based on the interference measurement information, determines scheduling information for the terminal based on the interference prediction information, and sends the scheduling information to the terminal. In this implementation, the network-side device performs interference prediction.
[0273] Whether interference prediction is performed by the terminal or the network-side equipment, the network-side equipment determines the scheduling information for the terminal based on the interference prediction information. This scheduling information includes at least one of the following: time-domain resources of PDSCH, frequency-domain resources of PDSCH, or MCS.
[0274] In this embodiment, the network-side device sends first auxiliary information to the terminal. This first auxiliary information is used by the terminal to perform interference prediction. The terminal performs interference prediction based on the first auxiliary information, which improves the accuracy of interference prediction. The network-side device can make better scheduling decisions based on the accurate interference prediction information obtained by the terminal.
[0275] It should be noted that the embodiments of the network-side device correspond to the embodiments of the terminal-side device. The information sent by the terminal is received by the network-side device, and the information sent by the network side is received by the terminal.
