[0004] In a communication system, a terminal can measure interference using interference measurement resources. These resources refer to the communication resources configured by the base station for the terminal to measure interference, such as Channel State Information Reference Signal (CSI-RS), Channel State Information for Interference Measurement (CSI-IM), and Interference Measurement Resource (IMR). The interference measured by the terminal is reported to the base station via Channel State Feedback (CSF). Since the base station is unaware of the interference experienced by the terminal on the target communication resources, it may be unable to schedule communication resources for the terminal based on the CSF report. This could lead to increased data transmission error rate, increased latency, and ultimately, reduced communication quality. Summary of the Invention

[0083] To better understand, the relevant concepts that may be involved in the embodiments of this application are explained below.
[0084] About Artificial Intelligence (AI):
[0085] AI has been widely applied in various fields. Integrating artificial intelligence into wireless communication networks to significantly improve technical indicators such as throughput, latency, and user capacity is an important task for future wireless communication networks. AI modules can be implemented in various ways, such as neural networks, decision trees, support vector machines, and Bayesian classifiers. This application uses neural networks as an example for illustration, but it does not limit the specific type of AI module.
[0086] Neural networks are composed of neurons. The parameters of a neural network are optimized using gradient optimization algorithms. Gradient optimization algorithms are a class of algorithms that minimize or maximize an objective function (sometimes called a loss function), which is often a mathematical combination of model parameters and data. For example, given data X and its corresponding label Y, we construct a neural network model f(.). With the model, we can obtain the predicted output f(x) based on the input x, and calculate the difference between the predicted value and the true value (f(x) - Y), which is the loss function. Our goal is to find suitable W and b that minimize the value of the loss function. The smaller the loss value, the closer our model is to the reality.
[0087] Most common optimization algorithms are based on the error back propagation (BP) algorithm. The basic idea of the BP algorithm is that the learning process consists of two parts: forward propagation of the signal and backward propagation of the error. During forward propagation, the input sample is introduced from the input layer, processed layer by layer by the hidden layers, and then propagated to the output layer. If the actual output of the output layer does not match the expected output, the process transitions to the error back propagation stage. Error back propagation involves propagating the output error back to the input layer layer by layer through the hidden layers, distributing the error to all units in each layer, thus obtaining the error signal of each unit. This error signal serves as the basis for adjusting the weights of each unit. This process of adjusting the weights through forward and backward propagation is repeated continuously. This continuous adjustment of weights is the learning and training process of the network. This process continues until the error of the network output is reduced to an acceptable level, or until the predetermined number of learning iterations is reached.
[0088] Common optimization algorithms include gradient descent, stochastic gradient descent (SGD), mini-batch gradient descent, momentum method, Nesterov (named after the inventor, specifically stochastic gradient descent with momentum), adaptive gradient descent (Adagrad), Adadelta, root mean square prop (RMSprop), and adaptive momentum estimation (Adam).
[0089] During error backpropagation, these optimization algorithms calculate the gradient based on the error / loss obtained from the loss function with respect to the current neuron, add the learning rate, previous gradients / derivatives / partial derivatives, etc., and then pass the gradient to the previous layer.
[0090] The AI unit described in this application may also be referred to as an AI model, machine learning (ML) model, ML unit, AI structure, AI function, AI characteristic, machine learning model, neural network, neural network function, neural network functionality, etc. Alternatively, the AI unit / AI model may refer to a processing unit capable of implementing specific algorithms, formulas, processing flows, capabilities, etc., related to AI. Or, the AI unit / AI model may be a processing method, algorithm, function, module, or unit for a specific dataset. Alternatively, the AI unit / AI model may be a processing method, algorithm, function, module, or unit running on AI / ML related hardware such as GPUs, NPUs, TPUs, and ASICs. This application does not impose specific limitations in this regard. Optionally, the specific dataset includes the input and / or output of the AI unit / AI model.
[0091] Optionally, the identifier of the AI unit / AI model may be an AI model identifier, an AI structure identifier, an AI algorithm identifier, or an identifier of a specific dataset associated with the AI unit / AI model, or an identifier of a specific scenario, environment, channel characteristics, or device related to the AI / ML, or an identifier of a function, feature, capability, or module related to the AI / ML. This application does not specifically limit this.
[0092] Regarding interference prediction:
[0093] Knowing predicted 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 are predicted to experience strong interference on 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.
[0094] The terminal side knows the interference information on the communication resources to be scheduled in the future. 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.
[0095] Interference experienced by a terminal may be caused by multiple sources, such as neighboring base stations, sidelink communication between other UEs, and other UEs. Interference experienced by a UE, also known as interference-plus-noise (IpN), can change rapidly in the time, frequency, and spatial domains. IpN refers to the sum of the interference power and noise power measured by the UE; in this application, interference also includes interference power or interference-plus-noise power. Interference experienced by 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. Figure 1b illustrates a schematic diagram of interference prediction based on an AI model.
[0096] On the one hand, interference prediction can be performed at the terminal side, meaning the terminal can predict future interference information on the second communication resource based on past interference measurements on the first communication resource. Then, the terminal can report the predicted interference information to the network side, or optimize the parameters of receiver-related algorithms based on the predicted interference information. As shown in Figures 1c and 1d, the terminal can predict interference information and report the predicted interference information.
[0097] On the other hand, interference prediction can be performed on the network side, i.e., the terminal reports interference measurements of the first communication resource to the network side. Then, based on the interference measurements reported by the terminal, the network side predicts the future interference information of the terminal on the second communication resource, and further determines the air interface resources allocated to the UE for data transmission or signaling transmission based on this information. The first and second communication resources may be the same, partially the same, or different, and are not limited here. The communication resources described in this application can be regarded as a collection of one or more of 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.
[0098] Terminals can measure interference using interference measurement resources. These resources refer to the communication resources configured by the base station for the UE to measure interference, such as Channel State Information Reference Signal (CSI-RS), Channel State Information for Interference Measurement (CSI-IM), and Interference Measurement Resource (IMR). A CSI-RS is a reference signal sent by the base station, which the terminal can use to estimate the channel and feed back channel state information to the base station or network nodes (hereinafter collectively referred to as the base station, which also includes other network nodes in the access network). A CSI-IM is a set of resource elements (REs) reserved for interference measurement. An IMR is a time-frequency resource allocated by the network to the UE for interference measurement. Interference measured by the terminal may be reported to the base station via Channel State Feedback (CSF). According to relevant protocols, a CSF report does not include interference-related information on specific time, frequency, or spatial resources. Interference-related information includes, but is not limited to: interference power measured or predicted in a specific time, frequency, or spatial domain; signal-to-interference-plus-noise ratio (SINR); power level; and carrier-to-interference ratio (C / I). Interference level is an indicator describing the intensity of interference. In one case, interference levels can be divided into three levels: high, medium, and low, which can be indicated using 2 bits to represent the current interference intensity. Alternatively, interference levels 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.
[0099] Since the base station is unaware of the interference experienced by the target UE on the target communication resources, it may also be unable to schedule communication resources for the UE based on interference-related information from the CSF report. In this case, the serving base station may configure or schedule communication resources with relatively high interference intensity for the UE, which may reduce the signal SINR and thus degrade communication performance, such as increasing the data transmission error rate and latency.
[0100] To enable base stations (including serving base stations or neighboring base stations) 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 base station. This interference-related information can be a set (including one or more) of measured or predicted interference values (such as interference power or SINR) obtained from at least one interference measurement instance, or a set (including one or more) of measured or predicted interference values and their corresponding probabilities. The at least one interference measurement instance can be obtained by the UE on a set of interference measurement resources in the time, frequency, or spatial domains. This set of interference measurement resources may include one or more CSI-RS, one or more CSI-IM, or one or more IMR. The measured interference value refers to the interference value obtained through at least one interference measurement instance. The predicted interference value refers to the future interference value predicted based on at least one past interference measurement instance.
[0101] The reported interference-related information may be in the form of a distribution-based representation or a non-distribution-based representation. For a distribution-based representation, the interference distribution reported by the terminal may be a probability density function related to the time, frequency, or spatial domains, or a probability mass function. 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:
[0102] R X ={x1,x2,x3,x4…}
[0103] The probability mass function of X is: P X (x k ) = P(X = x k ), k = 1, 2, 3, 4…
[0104] In one embodiment: the reported interference distribution 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.:
[0105] P(IpN=x k |t=t m f = f n ,s=s q ),
[0106] k = 1, 2, 3, 4…
[0107] m = 1, 2, 3, 4…
[0108] n = 1, 2, 3, 4…
[0109] q = 1, 2, 3, 4…
[0110] in,
[0111] x k This represents the power of the k-th interference, such as x1 = -30dBm, x2 = -31dBm, x3 = -32dBm…
[0112] t m This represents the m-th time-domain resource, such as t1 = slot1, t2 = slot2, t3 = slot3…
[0113] f n This represents the nth frequency domain resource, such as f1 = subband1, f2 = subband2, f3 = subband3...
[0114] s q This represents the q-th spatial resource, such as s1 = beamindex1, s2 = beamindex2, s3 = beamindex1. 3 …
[0115] In this embodiment, P(IpN=x k |t=t m f = f n ,s=s q This describes: the terminal in the time domain resource t m Frequency domain resources f n and airspace resources q The measured or predicted interference power is x k The probability of.
[0116] Of course, the granularity of time-domain resources, frequency-domain resources, and spatial-domain resources can also be other. 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.
[0117] The probability described in this application can also be replaced by descriptions such as confidence level, accuracy, uncertainty, and uncertainty range. The characteristics are: the larger the value, the higher the probability of occurrence, or the greater the confidence or credibility, or the higher the accuracy, or the lower the uncertainty, or the smaller the uncertainty range.
[0118] In one scenario, the base station might be configured with granularity for interference measurement or prediction, for example:
[0119] Frequency domain granularity: Interference measurement or 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 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: Base stations may configure multiple reference signal resources or beams for interference measurement or 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] Regarding the Demodulation Reference Signal (DMRS):
[0123] In current NR systems, DMRS is used for channel estimation. The NR standard's design for DMRS caters to various deployment scenarios and use cases: its front-end design reduces processing latency; support for up to 12 orthogonal antenna ports effectively supports Multiple-Input Multiple-Output (MIMO) applications; transmission durations range from 2 to 14 OFDM symbols, and up to 4 DMRS instances can be configured per time slot to support high-speed mobile scenarios. Placing DMRS before transmission, or as a front-end reference signal, helps the system achieve lower processing latency. This design allows the receiver to perform channel estimation earlier. Once the receiver obtains the channel estimate, regardless of whether the transmission has ended, it can immediately perform correlation demodulation on the already buffered received data, instead of receiving and buffering all data before processing.
[0124] The NR standard DMRS uses a length of 2 31The sequence is a Gold sequence of -1. The sequence generation corresponds to all common resource blocks in the frequency domain. However, during data transmission, only the resource blocks used for data transmission need to be selected for transmission; there is no need to estimate channels outside the frequency resources used for transmission. A unified reference signal sequence is generated for all resource blocks, providing a consistent sequence when different terminals use the same time-frequency resources. In Multi-User Multiple-Input Multiple-Output (MU-MIMO), the same resource blocks use the same sequence. Different users can superimpose orthogonal sequences on this pseudo-random sequence to maintain isolation between users and reduce interference. However, if the underlying pseudo-random sequence (or initial sequence) of each terminal is different, then even for the same time-frequency resource block, the sequence will be different.
[0125] Referring to Figures 1e and 1f, the DMRS for the data channel can be categorized into two configuration types based on its frequency domain structure: DMRS Configuration Type 1 and DMRS Configuration Type 2. Both configuration types support single-symbol and double-symbol structures. DMRS Configuration Type 1 supports a maximum of 4 ports for the single-symbol structure and a maximum of 8 ports for the double-symbol structure. DMRS Configuration Type 2 supports a maximum of 6 ports for the single-symbol structure and a maximum of 12 ports for the double-symbol structure. Furthermore, DMRS Configuration Type 1 supports 2 Code Division Multiplexing Groups (CDM groups), while DMRS Configuration Type 2 supports 3 CDM groups.
[0126] The NR standard supports two DMRS time-domain structures, the main difference being the position of the first DMRS symbol: Mapping Type A and Mapping Type B. Mapping Type A: The first DMRS symbol is located in the second or third OFDM symbol within the time slot. This mapping method always places the DMRS at a relative edge of the time slot, regardless of the actual start position of data transmission. Mapping Type B: The first DMRS symbol is located in the first OFDM symbol of data allocation. The position of the DMRS is not relative to the start position of the time slot, but rather relative to the start position of data transmission.
[0127] The interference information reporting method, receiving method, and related equipment provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.
[0128] Please refer to Figure 2, which is a flowchart of an interference information reporting method provided in an embodiment of this application. The method is executed by a terminal. As shown in Figure 2, the method includes the following steps:
[0129] Step 201: The terminal obtains the first configuration information.
[0130] It should be noted that the first configuration information may be sent to the terminal by the network-side device, and the first configuration information is used to instruct the terminal to report the predicted interference information.
[0131] The first configuration information includes at least one of the following:
[0132] The time-domain configuration for reporting the predicted interference information;
[0133] The frequency domain configuration for reporting the predicted interference information;
[0134] The spatial configuration for reporting the predicted interference information;
[0135] The first indication information is used to indicate that the predicted interference information is obtained based on DMRS.
[0136] It should be noted that the time-domain configuration for reporting the predicted interference information can be used to instruct the terminal to report predicted interference information on which time-domain resources in the future, such as frames, time slots, symbols, etc. The frequency-domain configuration for reporting the predicted interference information can be used to instruct the terminal to report predicted interference information on which frequency-domain resources in the future, such as broadband or sub-band granularity. The spatial-domain configuration for reporting the predicted interference information can be used to instruct the terminal to report predicted interference information on which spatial-domain resources in the future, such as physical cells, receiving ports, receiving branches, transport layers, etc.
[0137] In this embodiment of the application, the first configuration information includes at least one of the time domain configuration for reporting the predicted interference information, the frequency domain configuration for reporting the predicted interference information, and the spatial domain configuration for reporting the predicted interference information. This enables the terminal to determine, based on this configuration information, which time domain resources and / or frequency domain resources and / or spatial domain resources need to be predicted for interference information in the future, and to report the predicted interference information.
[0138] Optionally, the first configuration information further includes first indication information, which indicates that the predicted interference information is obtained based on DMRS. For example, the terminal can perform interference measurement based on DMRS and predict future interference information based on the interference measurement.
[0139] For example, the predicted interference information, obtained based on DMRS, can be achieved through at least one of the following:
[0140] The protocol stipulates, for example, that when the CSI Report Config is not associated with the CSI measurement configuration, the relevant interference measurement can be obtained based on DMRS; and for another example, when the CSI Report Config is not associated with the CSI measurement configuration and the reported quantity is the predicted interference information, the relevant interference measurement can be obtained based on DMRS.
[0141] The CSI Report Config indicates this;
[0142] Dynamic indications in Downlink Control Information (DCI) or Medium Access Control Element (MAC CE).
[0143] In this embodiment of the application, the interference information includes at least one of the following:
[0144] Signal-to-noise and interference ratio (SINR);
[0145] Interference power;
[0146] Interference plus noise power;
[0147] Channel quality indicator (CQI).
[0148] Optionally, the interference power or the interference plus noise power includes at least one of the following:
[0149] The difference between Received Signal Strength Indication (RSSI) and CSI reference signal received power (CSI-RSRP), for example, the predicted interference information is obtained based on CSI-RS;
[0150] The difference between RSSI and DMRS RSRP, for example, the predicted interference information is obtained based on DMRS.
[0151] It should be noted that RSRP can be obtained based on DMRS, for example, RSRP can be determined based on the linear average of the power on the RE carrying the DMRS.
[0152] In addition, for DMRS, multiple OFDM symbols carrying DMRS may be configured in a slot, and the resources associated with the calculation of RSSI and RSRP of DMRS may be related. For example, RSSI can be obtained based on OFDM symbols carrying DMRS, or based on multiple OFDM symbols in the slot carrying DMRS, or based on REs carrying DMRS.
[0153] Optionally, the RSSI is determined based on at least one of the following:
[0154] OFDM symbol carrying DMRS;
[0155] Multiple OFDM symbols in a time slot carrying DMRS;
[0156] RE carrying DMRS.
[0157] For example, RSSI can be obtained based on measurements of OFDM symbols carrying DMRS (e.g., measurements of OFDM symbols carrying DMRS on at least one receive branch). For instance, RSSI can be determined by the linear average of all RE powers of the OFDM symbols carrying DMRS within a frequency domain resource range; the frequency domain resource range can be the frequency domain resource range occupied by the DMRS, such as M PRBs. Alternatively, RSSI can also be obtained based on the DMRS, or based on multiple OFDM symbols in the slot carrying the DMRS.
[0158] In this embodiment, the predicted interference information is obtained based on DMRS. Compared with interference measurement based on CSI-RS, the interference prediction based on DMRS in this application helps to save the overhead of the reference signal.
[0159] The RSSI mentioned above can also be understood or replaced as the linear average of the received signal strength on the target RE. In one implementation, the terminal obtains the linear average y of the received signal power of the RE carrying DMRS, which includes the useful signal power from the serving cell and the interference plus noise power. By filtering the received signal, the useful signal power from the serving cell x, i.e., DMRS-RSRP, can be obtained, and the interference plus noise power is yx.
[0160] Step 202: The terminal reports the predicted interference information based on the first configuration information.
[0161] Understandably, after obtaining the first configuration information, the terminal performs interference information prediction based on the first configuration information.
[0162] For example, the first configuration information includes the time domain configuration for reporting the predicted interference information. The time domain configuration instructs the terminal to report the predicted interference information for several future target time slots. Then, based on the first configuration information, the terminal predicts the interference information for the future target time slots based on historical interference measurements. This interference information is also the predicted interference information.
[0163] It should be noted that the predicted interference information is obtained by the terminal based on the AI unit prediction.
[0164] For example, the terminal can predict interference information through an AI unit. For instance, the terminal inputs historical interference measurements based on DMRS into the AI unit, which then predicts future interference information in a specific time slot and outputs the predicted interference information. Thus, the terminal can predict interference information through the AI unit, effectively improving its performance in processing interference information.
[0165] After receiving the predicted interference information, the terminal reports it to the network-side device. This allows the network-side device to better schedule resources and coordinate interference between cells, reducing future interference to the terminal and improving link quality. For example, based on the predicted interference information, the network-side device can avoid scheduling users predicted to experience strong interference on future communication resources. Furthermore, the network can more accurately determine the Multi-Segment Compatibility (MCS) based on the predicted interference information, thereby reducing the initial block error rate and transmission latency.
[0166] In this embodiment, the terminal obtains first configuration information and reports predicted interference information based on the first configuration information. The first configuration information includes at least one of the following: time-domain configuration of the predicted interference information, frequency-domain configuration of the predicted interference information, spatial configuration of the predicted interference information, and first indication information. The first indication information indicates that the predicted interference information is obtained based on DMRS. Therefore, the solution provided in this application can predict future interference information on a certain time-domain resource and / or frequency-domain resource and / or spatial-domain resource based on DMRS. This allows network-side devices to better perform resource scheduling and interference coordination based on the predicted interference information reported by the terminal, reducing future interference experienced by the terminal and improving communication quality. Furthermore, compared to interference measurement based on CSI-RS, the interference prediction based on DMRS in this application helps save on reference signal overhead. Compared to CSI-RS-based interference prediction, the network side does not need to configure additional reference signal resources for the terminal for interference measurement or prediction. The terminal performs interference measurement based on the DMRS carried on the physical downlink shared channel or physical downlink control channel at the historical scheduling time, and predicts the interference information at several future times.
[0167] Optionally, when the first configuration information includes the time-domain configuration for reporting the predicted interference information, the time-domain configuration for reporting the predicted interference information includes at least one of the following:
[0168] (1) A first time-domain parameter, wherein the first time-domain parameter is used to indicate the number of consecutive time units associated with the predicted interference information reported by the terminal, wherein the time units include frames, time slots, symbols, etc.
[0169] (2) A second time-domain parameter, wherein the second time-domain parameter is used to indicate the duration of the time unit;
[0170] (3) Third time domain parameter, which is used to indicate the time domain start index or time domain start position of the first time unit in the continuous time unit associated with the predicted interference information. For example, the time domain start index may be a time offset relative to the uplink time unit of CSI or interference reporting.
[0171] (4) A fourth time-domain parameter, which is used to indicate the number of consecutive time frames associated with the predicted interference information reported by the terminal;
[0172] (5) Fifth time-domain parameter, which is used to indicate the time interval between adjacent time slots reported in each frame;
[0173] (6) A sixth time-domain parameter, which is used to indicate the index of the first time slot reported in each frame, for example, the index may be determined based on a time offset relative to the frame boundary;
[0174] (7) A seventh time-domain parameter, which is used to indicate the index of at least one time slot being reported;
[0175] (8) An eighth time-domain parameter, which is used to indicate the index of at least one reported frame.
[0176] Optionally, based on the above time-domain parameters, the method further includes at least one of the following:
[0177] (a) The terminal determines the number of time units associated with the predicted interference information based on the first time domain parameter. The time domain configuration for reporting the predicted interference information includes the first time domain parameter. Based on the first time domain parameter, the terminal can also determine which time units of the predicted interference information need to be reported in the future. For example, the terminal reports the predicted interference information for N consecutive time units in the future (N is a positive integer).
[0178] (b) The terminal determines the duration of the time unit based on the second time domain parameter, and the time domain configuration for reporting the predicted interference information includes the second time domain parameter; that is, the terminal can determine the duration of the time unit associated with the predicted interference information to be reported based on the second time domain parameter.
[0179] (c) The terminal determines the time-domain start position or time-domain start index of the first time unit associated with the predicted interference information based on the third time-domain parameter, so that the terminal can determine from which future time position to start the interference information prediction, wherein the time-domain configuration of the predicted interference information reporting includes the third time-domain parameter.
[0180] (d) The terminal determines the number of consecutive time frames associated with the reported predicted interference information based on the fourth time domain parameter. For example, the terminal reports the predicted interference information for M consecutive future time frames (M is a positive integer), wherein the time domain configuration of the reported predicted interference information includes the fourth time domain parameter.
[0181] (e) The terminal determines the time interval between adjacent time slots in each frame associated with the reported predicted interference information based on the fifth time domain parameter, wherein the time domain configuration of the reported predicted interference information includes the fifth time domain parameter.
[0182] (f) The terminal determines the index of the first time slot in each frame associated with the reported predicted interference information based on the sixth time domain parameter, wherein the time domain configuration of the reported predicted interference information includes the sixth time domain parameter.
[0183] (g) The terminal determines the index of at least one time slot associated with the reported predicted interference information based on the seventh time domain parameter, wherein the time domain configuration of the reported predicted interference information includes the seventh time domain parameter.
[0184] (h) The terminal determines the index of at least one frame associated with the reported predicted interference information based on the eighth time-domain parameter, wherein the time-domain configuration of the reported predicted interference information includes the eighth time-domain parameter.
[0185] In this embodiment of the application, the terminal can determine which future time units (such as time slots, frames, etc.) the predicted interference information to be reported is associated with based on the above time domain parameters, which helps the terminal to better predict interference information at the time domain granularity.
[0186] Optionally, the time-domain configuration for reporting the predicted interference information further includes at least one of the following:
[0187] The second indication information is used to instruct the terminal to report the predicted interference information of the time slot associated with the currently active Semi-Persistent Scheduling (SPS) configuration. This allows the network-side device to simultaneously schedule SPS and instruct the terminal on which time slots to predict interference information within a single DCI, which helps reduce the signaling overhead of network indication. Alternatively, the network-side device can schedule SPS within a single DCI and instruct the reporting of interference information of the time slot associated with SPS in the CSI reporting configuration, which also helps reduce the signaling overhead of network indication.
[0188] The third indication information is used to instruct the terminal to report the predicted interference information of the time slot associated with the first SPS configuration, wherein the first SPS configuration is the SPS configuration associated with the target SPS configuration index.
[0189] The fourth indication information is used to instruct the terminal to report the predicted interference information for L consecutive periods of SPS scheduling, where L is a positive integer. For example, if the SPS period is 5 milliseconds and the fourth indication information indicates reporting the predicted interference information for 4 consecutive periods, then the terminal can report the predicted interference information associated with the nth, n+5th, n+10th, and n+15th slots.
[0190] Optionally, the terminal reports the predicted interference information based on the first configuration information, including at least one of the following:
[0191] When the time-domain configuration of the predicted interference information reported includes the second indication information, the terminal reports the predicted interference information for at least one time slot associated with the currently active semi-persistent scheduling (SPS) configuration.
[0192] When the time-domain configuration for reporting the predicted interference information includes the third indication information, the terminal reports the predicted interference information for the time slot associated with the first SPS configuration.
[0193] When the time-domain configuration for reporting the predicted interference information includes the fourth indication information, the terminal reports the predicted interference information for L consecutive cycles of SPS scheduling.
[0194] In this embodiment of the application, the network-side device instructs the terminal to report the predicted interference information associated with the time-domain resources through the aforementioned second, third, and fourth indication information, thereby enabling the terminal to perform interference prediction on these time-domain resources, which helps the terminal to better achieve interference prediction.
[0195] Optionally, if the first time slot satisfies the first condition, the terminal does not report the interference information of the first time slot, where the first time slot is any time slot indicated in the time domain configuration for reporting the predicted interference information; wherein, satisfying the first condition for the first time slot includes any of the following:
[0196] (1) The first time slot does not contain downlink OFDM symbols;
[0197] (2) The first time slot includes downlink OFDM symbols and uplink OFDM symbols;
[0198] (3) The symbols contained in the first time slot are all uplink OFDM symbols.
[0199] Understandably, in the above three cases, network-side devices generally do not schedule the terminal's Physical Downlink Shared Channel (PDSCH) transmission. Consequently, for the terminal, when the first time slot meets the first condition in the above three cases, the terminal's reporting of interference information in the first time slot has almost no improvement on transmission performance. Therefore, when the first time slot meets the first condition, the terminal does not report interference information in the first time slot, thereby helping to save the terminal's reporting overhead.
[0200] Optionally, the frequency domain configuration for reporting the predicted interference information includes:
[0201] The fifth indication information is used to instruct the terminal to report the predicted broadband interference information or the predicted interference information of at least one subband.
[0202] In this embodiment of the application, when the first configuration information includes the frequency domain configuration for reporting the predicted interference information, and the frequency domain configuration for reporting the predicted interference information includes the fifth indication information, the terminal reports the predicted interference information based on the first configuration information, including:
[0203] The terminal reports the predicted broadband interference information or the predicted interference information of at least one sub-band based on the frequency domain configuration of the predicted interference information.
[0204] For example, the fifth indication information is used to instruct the terminal to report the predicted broadband interference information. In this case, the terminal reports the predicted broadband interference information based on the fifth indication information.
[0205] Alternatively, the fifth indication information may be used to instruct the terminal to report the interference information of at least one predicted sub-band. In this case, the terminal reports the interference information of at least one predicted sub-band.
[0206] Understandably, the network-side device uses the fifth indication information to instruct the terminal to report the predicted broadband or at least one subband interference information, so that the terminal can determine whether to perform broadband-based interference information prediction or subband-based interference information prediction based on the fifth indication information.
[0207] Optionally, the frequency domain configuration for reporting the predicted interference information is further used to indicate the sub-band index, and the terminal reports the predicted sub-band interference information based on the frequency domain configuration for reporting the predicted interference information, including:
[0208] The terminal determines the first sub-band corresponding to the sub-band index and reports the predicted interference information of the first sub-band.
[0209] Understandably, the network-side device can also indicate the subband index to the terminal, so that the terminal can determine the subband corresponding to the subband index. In this way, the terminal can accurately know which subbands need to be predicted for interference information, making the terminal's interference prediction more targeted.
[0210] Optionally, the first configuration information sent by the network-side device to the terminal includes the frequency domain configuration for reporting the predicted interference information, and the frequency domain configuration for reporting the predicted interference information may further include at least one of the following:
[0211] The sixth indication information is used to instruct the terminal to report the predicted interference information on the frequency domain resources allocated in the most recent DCI scheduling.
[0212] The seventh indication information is used to instruct the terminal to report the predicted interference information on the frequency domain resources allocated by the DCI in the most recent SPS scheduling;
[0213] The eighth indication information is used to instruct the terminal to report the predicted interference information on the frequency domain resources occupied by the DMRS;
[0214] The ninth indication information is used to indicate the frequency domain resources for the predicted interference information that the terminal needs to report.
[0215] Optionally, when the first configuration information includes the frequency domain configuration for reporting the predicted interference information, the terminal reports the predicted interference information based on the first configuration information, including at least one of the following:
[0216] The terminal reports the predicted interference information on the frequency domain resources allocated in the most recent DCI scheduling, for example, the terminal reports the predicted interference information on the frequency domain resources allocated in the most recent DCI scheduling based on the sixth indication information.
[0217] The terminal reports the predicted interference information on the frequency domain resources allocated by the DCI in the most recent SPS scheduling, for example, the terminal reports the predicted interference information on the frequency domain resources allocated by the DCI in the most recent SPS scheduling based on the seventh indication information.
[0218] The terminal reports the predicted interference information on the frequency domain resources occupied by the DMRS, for example, the terminal reports the predicted interference information on the frequency domain resources occupied by the DMRS based on the eighth indication information.
[0219] The terminal reports the interference information predicted on the frequency domain resources indicated by the network-side device. For example, the terminal reports the interference information predicted on the frequency domain resources indicated by the network-side device based on the ninth indication information.
[0220] It should be noted that, given that the precoding resource group (PRG) has a wide bandwidth, the terminal can report the interference information predicted on the frequency domain resources occupied by the DMRS, which helps to improve the channel estimation accuracy.
[0221] In this embodiment, the terminal can determine which frequency domain resources the predicted interference information needs to be reported based on the above-mentioned indication information from the network-side device, thereby helping the terminal to more accurately predict the interference information.
[0222] Optionally, when the terminal reports the predicted interference information on the first frequency domain resource based on the frequency domain configuration reported by the predicted interference information, the method further includes:
[0223] The terminal reports the frequency domain location information of the first frequency domain resource.
[0224] It should be noted that the first frequency domain resource can be any frequency domain resource determined by the frequency domain configuration reported by the terminal based on the predicted interference information. Optionally, determining the first frequency domain resource includes at least one of the following:
[0225] The terminal determines the frequency domain resources allocated in the most recent DCI scheduling as the first frequency domain resources;
[0226] The terminal determines the frequency domain resources allocated by the DCI in the most recent SPS scheduling as the first frequency domain resources;
[0227] The terminal identifies the frequency domain resources occupied by DMRS as the first frequency domain resources;
[0228] The terminal identifies the frequency domain resource indicated by the network-side device as the first frequency domain resource.
[0229] Therefore, the terminal can determine the first frequency domain resource based on the above method and report the frequency domain location information of the first frequency domain resource. The frequency domain location information can be a frequency domain resource index, such as a PRB index, RB index, subband index, etc. By reporting the frequency domain location information of the first frequency domain resource, the network-side device can accurately know which frequency domain resource is associated with the predicted interference information reported by the terminal, which is more helpful for the network-side device to perform resource scheduling based on the predicted interference information.
[0230] In this embodiment of the application, when the first configuration information includes the spatial configuration for reporting the predicted interference information, the terminal reports the predicted interference information based on the first configuration information, including at least one of the following:
[0231] The terminal reports predicted interference information associated with at least one Transmission Configuration Indicator (TCI) status indicated by the network-side device.
[0232] The terminal reports interference information predicted in at least one receiving branch;
[0233] The terminal reports interference information predicted at at least one transport layer.
[0234] For example, if a network-side device indicates at least one TCI state, the terminal may report predicted interference information associated with one of the at least one TCI states indicated by the network-side device. For instance, the terminal reporting predicted interference information under at least one TCI state indicated by the network-side device includes:
[0235] The terminal uses the interference measurement associated with one of the at least one TCI states indicated by the network-side device to perform interference prediction and obtain the predicted interference information.
[0236] The terminal reports the predicted interference information.
[0237] The TCI state used by the terminal can be any one of at least one TCI state indicated by the network-side device.
[0238] Alternatively, the terminal can report predicted interference information associated with multiple TCI states in at least one TCI state indicated by the network-side device, making the terminal's reporting of predicted interference information more flexible.
[0239] Optionally, when the spatial configuration for reporting interference information includes network-side device instructions to report predicted interference information associated with at least two TCI states, the terminal reporting the predicted interference information includes any one of the following:
[0240] The terminal reports the predicted interference information associated with the at least two TCI states through a CSI feedback report;
[0241] The terminal reports the predicted interference information associated with the at least two TCI states through at least two CSI feedback reports;
[0242] The interference information predicted under the at least two TCI states corresponds to different time-frequency domain configurations, or the interference information predicted under the at least two TCI states corresponds to the same time-frequency domain configuration.
[0243] In this embodiment, when the network-side device instructs the reporting of predicted interference information associated with at least two TCI states, the terminal, after receiving the predicted interference information associated with the at least two TCI states, can either report all the predicted interference information in one CSI feedback report, or report the predicted interference information separately through different CSI feedback reports, with one CSI feedback report used to report the predicted interference information associated with one TCI state. This makes the terminal's reporting method for predicted interference information in the at least two TCI states more flexible.
[0244] In addition, the interference information predicted under the at least two TCI states may correspond to different time-frequency domain configurations, or they may correspond to the same time-frequency domain configuration, thereby making the time-domain configuration, frequency-domain configuration and spatial-domain configuration associated with the predicted interference information more flexible.
[0245] Optionally, the method further includes:
[0246] The terminal reports the TCI status identifiers associated with the at least two TCI states respectively.
[0247] In this way, the network-side device can know which TCI states are associated with the predicted interference information reported by the terminal based on the TCI status identifier, which helps the network-side device to perform resource scheduling based on the predicted interference information.
[0248] It should be noted that the predicted interference information reported by the terminal can be associated with the same TCI state or the same Precoding Matrix Indicator (PMI); or, the interference measurement information used by the terminal to perform interference prediction is obtained based on DMRS, which have the same TCI state or the same Quasi Co-location (QCL) relationship, such as QCL-D; or, the terminal can use DMRS with the same TCI state to obtain the predicted interference information.
[0249] In this embodiment, the terminal may also report interference information predicted in at least one receiving branch. Wherein, one receiving branch is associated with a receiving port or a transport layer, and the interference information predicted in at least one receiving branch reported by the terminal includes any of the following:
[0250] The terminal obtains the minimum value among the interference values predicted by at least one receiving branch, and the terminal reports a first target interference value, wherein the first target interference value is one or more interference values among the predicted interference values that are not less than the minimum value.
[0251] The terminal acquires the interference value predicted by each of the at least one receiving branches, and the terminal reports a second target interference value, wherein the second target interference value is not less than the interference value predicted by any one of the receiving branches.
[0252] The terminal reports the maximum interference value among the interference values predicted by at least one receiving branch.
[0253] The terminal reports the average value of the interference predicted in at least one receiving branch.
[0254] Understandably, a terminal can use multiple receiving branches (e.g., receiving ports) to receive signals. Each receiving branch will measure corresponding interference information (e.g., interference value). The interference values measured by different receiving branches are different. Therefore, the terminal can report the predicted interference value based on the following methods:
[0255] Method 1: The terminal obtains the minimum value among the interference values predicted by at least one receiving branch, and the terminal selects the predicted interference values (i.e. the target interference value) that are greater than the minimum value and reports them. One or more of these can be reported.
[0256] Method 2: The terminal obtains the interference value predicted by each of the at least one receiving branches, and the terminal reports the second target interference value. The interference value predicted by the at least one receiving branch includes the second target interference value, and the second target interference value is not less than the interference value predicted by any one of the receiving branches.
[0257] Method 3: The terminal obtains the maximum interference value among the interference values predicted by at least one receiving branch, and the terminal reports the maximum interference value;
[0258] Method 4: The terminal obtains the predicted interference value in each receiving branch, and obtains the average value of these predicted interference values. The terminal then reports this average value.
[0259] This makes the terminal more flexible in reporting interference values based on the predicted reception branch.
[0260] Optionally, when the terminal reports interference information predicted in at least one receiving branch, the interference measurement associated with the predicted interference information reported by the terminal is obtained based on the same receiving port, the same receiving beam, or the same spatial filter; or, the DMRS associated with the predicted interference information reported by the terminal is quasi-co-located; or the DMRS associated with the predicted interference information reported by the terminal has the same QCL relationship, such as QCL-D.
[0261] In this embodiment of the application, the terminal may also report interference information predicted at at least one transport layer.
[0262] For example, the terminal can perform interference prediction based on interference measurements at each transport layer to obtain predicted interference information for each transport layer, and then report the predicted interference information for each transport layer separately. Alternatively, the terminal can perform interference prediction based on interference measurements from multiple transport layers combined, and then report the combined predicted interference information from multiple transport layers. Or, the terminal can perform interference prediction separately based on interference measurements at each transport layer, and then combine the predicted interference information from multiple transport layers before reporting the predicted interference information. In this way, the terminal can flexibly report predicted interference information from multiple transport layers.
[0263] In some implementations, the protocol may instruct the terminal to report the predicted interference information of the strongest transport layer, or the predicted interference information of the weakest transport layer, or the predicted interference information of all transport layers associated with the DMRS.
[0264] In this embodiment, the terminal can predict future interference information on a certain time domain resource and / or frequency domain resource and / or spatial domain resource based on DMRS. As a result, the network-side device can better perform resource scheduling and interference coordination based on the predicted interference information reported by the terminal, thereby reducing the interference received by the terminal in the future and improving the communication quality of the terminal.
[0265] Please refer to Figure 3, which is a flowchart of an interference information receiving method provided in an embodiment of this application. The method is executed by a network-side device. As shown in Figure 3, the method includes the following steps:
[0266] Step 301: The network-side device sends the first configuration information to the terminal;
[0267] Step 302: The network-side device receives the predicted interference information reported by the terminal based on the first configuration information;
[0268] The first configuration information includes at least one of the following:
[0269] The time-domain configuration for reporting the predicted interference information;
[0270] The frequency domain configuration for reporting the predicted interference information;

For example, the third time domain parameter is used to indicate the time index of the first time slot reported by the terminal.
[0318] (4) Fourth time domain parameter, which is used to indicate the number of consecutive time frames associated with the predicted interference information reported by the terminal.

[0326] The fourth indication information is used to instruct the terminal to report the predicted interference information of SPS scheduling for L consecutive cycles, where L is a positive integer.
[0327] Optionally, the time-domain configuration for reporting the predicted interference information may further include the following indication: if the first time slot meets a first condition, the terminal does not report the interference information of the first time slot, where the first time slot is any time slot indicated in the time-domain configuration for reporting the predicted interference information; wherein, the first condition for the first time slot includes any one of the following:

[0329] (2) The first time slot includes downlink OFDM symbols and uplink OFDM symbols;

[0331] For example, please refer to Figures 4a to 4d, where the reference time in Figures 4a to 4d can be the uplink slot reported by CSI.
[0332] In Figure 4a, if the network-side device instructs the terminal to report the predicted interference information for the next frame through the fourth time-domain parameter and instructs the reporting of at least one time slot index as 0, 2, 4, 7 through the seventh time-domain parameter, then the terminal reports the predicted interference information for the time slots indexed as 0, 2, 4, 7 in the next frame based on the fourth and seventh time-domain parameters.
[0333] In Figure 4b, if the network-side device instructs the terminal to report the predicted interference information for the next two frames through the fourth time-domain parameter, and instructs the reporting of at least one time slot index as 0, 2, 4, 7 through the seventh time-domain parameter, then the terminal reports the predicted interference information for the time slots indexed as 0, 2, 4, 7 in the next two frames based on the fourth and seventh time-domain parameters.
[0334] In Figures 4c and 4d, if the network-side device instructs the terminal to report the predicted interference information for four consecutive cycles of SPS scheduling through the fourth indication information, the terminal reports the predicted interference information for four consecutive cycles of SPS scheduling based on the fourth indication information.

[0345] Optionally, when the terminal reports the predicted interference information on the first frequency domain resource based on the frequency domain configuration reported by the terminal, the terminal reports the frequency domain location information of the first frequency domain resource.
[0346] For example, referring to Figure 4e, the network-side device instructs the terminal to report predicted interference information on the frequency domain resources allocated by DCI scheduling through the sixth instruction information, and instructs the terminal to report broadband-based predicted interference information through the fifth instruction information. Then, the terminal reports the predicted interference information on the frequency domain resources allocated by DCI scheduling on the broadband.
[0347] In this embodiment, the first configuration information includes the frequency domain configuration for reporting the predicted interference information, so that the network-side device can instruct the terminal to report the predicted interference information on which frequency domain resources based on the frequency domain configuration, which helps the network-side device to perform resource scheduling based on the reported predicted interference information.

[0355] Optionally, the predicted interference information reported by the terminal is associated with the same receiving port or receiving beam; or the terminal should use the DMRS received on the same receiving port or receiving beam for interference prediction.
[0356] It should be noted that if the network-side device instructs the terminal to report the predicted interference information associated with at least two TCI states, the terminal reports the predicted interference information associated with the at least two TCI states through a CSI feedback report; or, the terminal reports the predicted interference information associated with the at least two TCI states through at least two CSI feedback reports respectively.
[0357] The interference information predicted under the at least two TCI states corresponds to different time-frequency domain configurations, or the interference information predicted under the at least two TCI states corresponds to the same time-frequency domain configuration.
[0358] For multiple receiving branches, each receiving branch will measure corresponding interference information. Generally, the interference information measured by different receiving branches is different. In this case, the terminal can report the predicted interference information based on the following method:
[0359] The terminal obtains the minimum value among the interference values predicted by at least one receiving branch, and the terminal reports a first target interference value, wherein the first target interference value is one or more interference values among the predicted interference values that are not less than the minimum value;
[0360] The terminal acquires the interference value predicted by each of the at least one receiving branches, and the terminal reports a second target interference value, wherein the second target interference value is not less than the interference value predicted by any one of the receiving branches.
[0361] The terminal reports the maximum interference value among the interference values predicted by at least one receiving branch;
[0362] The terminal reports the average value of the interference predicted in at least one receiving branch.
[0363] For example, referring to Figures 4f and 4g, the terminal can perform interference prediction using interference measurements obtained from DMRS with TCI stateID=1 based on the TCI state index indicated by the network-side device; or, the terminal can perform interference prediction using interference measurements obtained from DMRS with TCI stateID=2; wherein the terminal receives DMRS with TCI stateID=1 or DMRS with TCI stateID=2 using the same RX beam or RX port.
[0364] In this embodiment, the first configuration information includes the airspace configuration for reporting the predicted interference information, so that the network-side device can instruct the terminal to report the predicted interference information on which airspace resources based on the airspace configuration, which helps the network-side device to perform resource scheduling based on the reported predicted interference information.
