To facilitate understanding, some contents involved in the embodiments of this application are described below:

1. Artificial intelligence.

Artificial Intelligence (AI) is currently widely used in various fields. There are many ways to implement AI modules, such as neural networks, decision trees, support vector machines, Bayesian classifiers, etc. This application takes neural network as an example for explanation, but does not limit the specific type of AI module.

Neural networks are composed of neurons, and the schematic diagram of neurons is shown in Figure 2. Among them, z＝a ₁ *w ₁ +···+a ₁ *w ₁ +···+a _k *w _k +b, a ₁ , a ₂ ,...a _K is the input, w is the weight (or is called the multiplicative coefficient), b is the bias (or is called the additive coefficient), and σ(.) is the activation function. Common activation functions include Sigmoid, hyperbolic tangent function (tanh), linear rectifier function (Rectified Linear Unit, ReLU), etc.

The parameters of the neural network are optimized through optimization algorithms. An optimization algorithm is a type of algorithm that can help us minimize or maximize an objective function (sometimes also called a loss function). The objective function is often a mathematical combination of model parameters and data. For example, given data X and its corresponding label Y, we build a neural network model f(.). With the model, we can get the predicted output f(x) based on the input The difference between (f(x)-Y), this is the loss function. Our purpose is to find appropriate w and b to minimize the value of the above loss function. The smaller the loss value, the closer our model is to the real situation.

Currently, common optimization algorithms are basically based on the error back propagation (error back propagation, BP) algorithm. The basic idea of BP algorithm is that the learning process consists of two processes: forward propagation of signals and back propagation of errors. During forward propagation, the input sample is passed in from the input layer, processed layer by layer by each hidden layer, and then transmitted to the output layer. If the actual output of the output layer does not match the expected output, it will enter the error backpropagation stage. Error backpropagation is to propagate the output error back to the input layer in some form through the hidden layer layer by layer, and distribute the error to all units in each layer, thereby obtaining the error signal of each layer unit, and this error signal is used as a correction for each unit The basis for the weight. This process of adjusting the weights of each layer in forward signal propagation and error back propagation is carried out over and over again. The process of 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 a preset number of learning times.

Common optimization algorithms include gradient descent (Gradient Descent), stochastic gradient descent (Stochastic Gradient Descent, SGD), mini-batch gradient descent (mini-batch gradient descent), momentum method (Momentum), and stochastic gradient descent with momentum (you can also Called Nesterov), Adaptive Gradient Descent (AdaGrad), Adaptive Delta Gradient Descent (AdaDelta), root mean square error reduction (root mean square prop (RMSprop)), and adaptive momentum Adaptive Moment Estimation, Adam.

When these optimization algorithms perform error backpropagation, they calculate the derivative/partial derivative of the current neuron based on the error/loss obtained by the loss function, plus the influence of the learning rate, previous gradient/derivative/partial derivative, etc., to obtain the gradient. Pass the gradient to the previous layer.

2. Regarding the beam indication mechanism.

After beam measurement and beam reporting, the network side device can perform beam indication on the downlink and uplink channels or reference signals, which is used to establish beam links between the network side device and the terminal to realize the transmission of the channel or reference signal.

For the beam indication of the physical downlink control channel (Physical downlink control channel, PDCCH), the network side device uses Radio Resource Control (Radio Resource Control, RRC) signaling to configure K transmissions for each control resource set (Control resource set, CORESET) Configuration indication (Transmission Configuration Indication, TCI) state (state), when K>1, the Media Access Control Control Unit (Medium Access Control Control Element, MAC CE) indicates or activates a TCI state, when K=1 , no additional MAC CE commands are required. When the terminal monitors the PDCCH, it uses the same quasi-colocation (QCL) for all search spaces in the CORESET, that is, the same TCI state to monitor the PDCCH. The reference signal (Reference Signal) in this TCI state and the terminal-specific (UE-specific) PDCCH demodulation reference signal (Demodulation Reference Signal, DMRS) port are spatial QCL. The terminal can learn which receiving beam to use to receive the PDCCH according to the TCI status. Among them, the reference signal in the TCI state can be a periodic channel state information reference signal (Channel State Information Reference Signal, CSI-RS), semi-persistent CSI-RS and synchronization signal block (Synchronization Signal and PBCH block, SSB), etc.

For the beam indication of the physical downlink shared channel (PDSCH), the network side device configures M TCI states through RRC signaling, then uses the MAC CE command to activate 2N TCI states, and then uses the downlink control information (Downlink Control Information) , the N-bit TCI field (field) of DCI) is used to notify the TCI status. The reference Signal in the TCI status is QCL with the DMRS port of the PDSCH to be scheduled. The UE can learn which receiving beam is used to receive the PDSCH according to the TCI status.

For the beam indication of CSI-RS, when the CSI-RS type is periodic CSI-RS, the network side device configures QCL information for the CSI-RS resource through RRC signaling. When the CSI-RS type is semi-persistent CSI-RS, the network side device uses the MAC CE command to indicate its QCL information when activating a CSI-RS resource from the CSI-RS resource set configured in RRC. When the CSI-RS type is aperiodic CSI-RS, the network side device configures QCL for the CSI-RS resource through RRC signaling and uses DCI to trigger CSI-RS.

For the beam indication of the Physical Uplink Control Channel (PUCCH), the network The network side device uses RRC signaling to configure spatial relation information for each PUCCH resource through the parameter PUCCH-SpatialRelationInfo. When the spatial relation information configured for the PUCCH resource contains multiple spatial relation information, use MAC-CE to indicate or activate one of them. spatial relation information. When the spatial relation information configured for the PUCCH resource only contains one piece, no additional MAC CE command is required.

For the beam indication of the Physical Uplink Shared Channel (PUSCH), the spatial relation information of the PUSCH is the Sounding Reference Signal resource indicator (SRI) field in the DCI when the DCI carried by the PDCCH schedules the PUSCH. Each SRI code point (codepoint) indicates an SRI, which is used to indicate the spatial relation information of PUSCH.

For the beam indication of the Sounding Reference Signal (SRS), when the SRS type is periodic SRS, the network side device configures spatial relation information for the SRS resource through RRC signaling. When the SRS type is semi-persistent SRS, the network side device uses the MAC CE command to activate one from a set of spatial relation information configured in RRC. When the SRS type is aperiodic SRS, the network side device configures spatial relation information for the SRS resource through RRC signaling.

For further improvement of beam indication, TCI unified indication (unified TCI indication) is proposed. Simply put, it indicates subsequent reference signals and beam information of multiple channels through the TCI domain in a DCI.

Optionally, the beam information, spatial relation information, spatial domain transmission filter information, spatial filter information, TCI state information, QCL information, QCL parameters and beam correlation mentioned in this application Relationships, etc., have approximately the same meaning.

Among them, downlink beam information can usually be represented by TCI state information and QCL information. Uplink beam information can usually be expressed using spatial relation information.

3. About beam measurement and beam reporting.

Analog beamforming is transmitted with full bandwidth, and each polarization direction array element on the panel of each high-frequency antenna array can only transmit analog beams in a time-division multiplexing manner. The shaping weight of the analog beam is achieved by adjusting the parameters of equipment such as the RF front-end phase shifter.

Currently, in academia and industry, the polling method is usually used for training of analog beamforming vectors, that is, the array elements of each polarization direction of each antenna panel send training signals at an agreed time in a time-division multiplexing manner ( That is, the candidate shaping vector), the terminal feeds back the beam report after measurement, so that the network side device can use the training signal to implement simulated beam transmission when transmitting services next time. The content of the beam report usually includes several optimal transmit beam identifiers and the measured received power of each transmit beam.

When performing beam measurements, the network side device configures a reference signal resource set (RS resource set), which includes at least one reference signal resource, such as SSB resource or CSI-RS resource. The UE measures the Layer 1 Reference Signal Received Power (L1-RSRP)/Layer 1 Signal to Interference plus Noise Ratio (L1-SINR) of each RS resource, and The optimal at least one measurement result is reported to the network side device, and the reported content includes synchronization signal block resource indication (Synchronization Signal and PBCH block Resource Indicator (SSBRI) or CRI, and L1-RSRP/L1-SINR. The report content reflects at least one optimal beam and its quality for the network side device to determine the beam used to send channels or signals to the terminal.

When the terminal feedback report contains only one L1-RSRP, the 7-bit quantization method is used, the quantization step is 1dB, and the quantization range is -140dBm to -44dBm. When the terminal is instructed that the feedback report contains multiple L1-RSRPs, or group-based beam report is enabled, the strongest RSRP quantization uses 7-bit quantization, and the remaining RSRP quantization uses the 4-bit differential quantization method. , the quantization step is 2dB.

Optionally, the number of feedback reports is determined by the parameters configured by the network side device to the terminal. Through the RRC configuration parameters, configure the number of RS and RSRP that should be included in the feedback report of the terminal. The value of the quantity configuration is 1, 2 , 3 or 4, the default value is 1. In addition, this quantity limit is based on the terminal capability, and the terminal will first report the maximum quantity it can support.

4. Use AI methods for beam prediction.

One possible method is shown in Figure 3, using the RSRP of some beam pairs as input, and the output of the AI model is the RSRP results of all beam pairs. Among them, the beam pair is composed of a transmitting beam and a receiving beam. The input number of the AI model is the number of selected partial beam pairs, and the output number is the number of all beam pairs.

There are also methods to enhance beam prediction performance. As shown in Figure 4 below, correlation information is added to the input side. The correlation information is generally angle-related information corresponding to the beam pairs selected for input, and beam identification (ID) information. wait. Therefore, the number of inputs to this model is still related to the number of selected partial beam pairs, and the number of outputs is still equal to the number of all beam pairs.

There is also an improved method based on the above, as shown in Figure 5. It mainly affects the output of the AI model by changing the expected information through the AI model.

Among them, the input types of the AI model include at least one of the following:

Beam quality related information;

Beam-related associated information;

The sending end sends beam-related association information;

The receiving end receives associated information related to the beam;

Correlation information related to the beam expected by the receiving end;

The associated information related to the receiving beam expected by the receiving end;

The receiving end expects the transmitting end to send beam-related association information;

Time-related information related to beam quality information;

Desired forecast time related information.

The related information related to the beam refers to the related information corresponding to the beam. The related information includes but is not limited to at least one of the following: beam ID related information, beam angle related information, beam gain related information, beam width related information, etc.

When applying the AI model, the following situations will exist:

A possible process is that if the AI model is located on the terminal side, the terminal obtains at least one optimal wave based on the AI model prediction. Beam, the terminal feeds back at least one optimal beam predicted. At this time, after the base station receives the feedback information, based on the feedback information, the base station configures and sends at least one predicted optimal beam. After receiving it, the terminal performs measurements and feeds back the measurement results. Therefore, there are two feedback methods. One is prediction feedback, which feeds back the predicted value. The other is normal measurement feedback, a measurement feedback method based on related technologies.

Another possible process is that if the AI model needs to perform model training, performance monitoring, and feedback of measurement results for prediction, the feedback report often needs to contain more measurement results. Here, there are also two feedback methods. One is a measurement feedback method based on related technologies, that is, normal measurement feedback. The other is that the feedback report needs to contain more measurement results, which is enhanced measurement feedback.

Optionally, the above feedback report may be called a measurement report.

The measurement feedback processing method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.

Step 601: The terminal performs measurement on the reference signal; the measurement in the embodiment of the present application may include but is not limited to beam measurement.

Step 602: The terminal sends a measurement report of the measurement to the network side device; wherein, the measurement report in the embodiment of the present application may also be called measurement feedback, and the measurement report may include but is not limited to a beam measurement report, and the measurement feedback includes but Not limited to beam measurement feedback.

Wherein, the measurement report satisfies at least one of the following:

In the embodiment of the present application, the measurement report type of the above measurement report may include any of the following: normal measurement report, Predictive measurement reporting and enhanced measurement reporting.

The above-mentioned normal measurement report can be understood as a regular measurement report, for example, based on the last measurement result, reporting the information corresponding to the previous one or more reference signals and/or channel quality information with the measurement results sorted from high to low.

The above predicted measurement report can be understood as a measurement report that is fed back after beam prediction based on the measurement results. The beams corresponding to the beam prediction may include beams other than the beams configured for measurement. For example, the network side device is configured to perform measurement. The beams are beam 1 to beam 10 (that is, the measurement beams associated with the measurement report), the predicted beams after measurement are beam 1 to beam 256, and the last feedback beam is the 20th beam. In other words, the information corresponding to the reference signal in the measurement report may not be included in the information corresponding to the reference signal of the measurement beam associated with the measurement report. Optionally, the above-mentioned beam prediction can be understood as using an AI model to perform beam prediction. For example, the measurement results can be input into the AI model to obtain the beam prediction results.

The above enhanced measurement report can be understood as an enhancement of the measurement report. The enhanced measurement report is equivalent to increasing the amount of feedback information in the measurement report. For example, in some embodiments, if the measurement is periodic, feedback information corresponding to the measurement results of multiple periods may be included. The feedback information includes reference At least one of signal corresponding information and channel quality information.

It should be noted that the amount of target information can be understood as the amount of information corresponding to the above-mentioned reference signal, or the amount of information corresponding to the reference signal, or can be understood as the amount of information corresponding to the reference signal and channel quality information together, where, reference The information corresponding to the signal and the channel quality information are related to each other. For example, the network side device configures the terminal to configure the number of target information contained in the measurement report to be 4. In fact, the feedback measurement report contains 4 RSRPs and the indexes of the reference signals corresponding to the 4 RSRPs. In this case, the second number is 4, which can be It can be expressed as the number of RSRPs, or it can be expressed as the number of indexes of the reference signals corresponding to the RSRPs, or it can also be expressed as the number of RSRPs and the indexes of the reference signals corresponding to the RSRPs together (or together).

Optionally, the information corresponding to the above-mentioned reference signal may be called beam information. In some embodiments, the information corresponding to the above-mentioned reference signal includes at least one of the following: information used to determine the spatial filter identification of the transmission direction, Information to determine the airspace filter identification in the receiving direction, information used to determine the airspace filter identification, angle-related information in the transmitting direction, angle-related information in the receiving direction, angle-related information, airspace filter expectation-related information in the transmitting direction and the receiving direction Spatial filter expects relevant information.

In other words, the above-mentioned beam information includes at least one of the following: information related to the beam identification of the transmitting beam, information related to the beam identification of the receiving beam, information related to the beam identification of the beam pair, information related to the angle of the transmitting beam, and information related to the angle of the receiving beam. , angle related information, beam gain related information, beam width related information, transmit beam expectation related information and receive beam expectation related information.

Among them, the beam identification related information is used to represent the relevant information of the identity recognition of the beam, including but not limited to at least one of the following: beam ID, reference signal set (set) ID corresponding to the beam, reference signal resource (resource) corresponding to the beam )ID, uniquely identified random ID, coded value and angle-related information processed by additional AI network, etc. For example, in some embodiments, the beam identity related information may include a Channel State Information Reference Signal Resource Indicator (CRI) and a synchronization signal block resource indicator. (Synchronization Signal and PBCH block Resource Indicator, SSBRI) etc.

Optionally, the above-mentioned angle-related information is used to characterize the angle-related information corresponding to the beam. The angle-related information is specifically used to characterize the angle or identity-related information, such as angle, radian, index code value, ID value and additional AI network processing. coded values, etc.

Optionally, in some embodiments, the channel quality information includes at least one of the following: signal to interference plus noise ratio of layer 1, reference signal reception power of layer 1, reference signal reception quality of layer 1, layer 3 Signal to Interference Plus Noise Ratio (L3-SINR), Layer 3 Reference Signal Received Power (L3-RSRP), and Layer 3 Reference Signal Received Quality (L3-RSRQ).

Optionally, the measurement report associating the target information and the first quantity indication information can be understood as: the measurement report contains the target information and the first quantity indication information, or the measurement report is associated with the target information and the first quantity indication information. Since the measurement report is associated with the first quantity indication information, the terminal does not need to provide feedback according to the quantity of target information configured by the network side device, thereby reducing the quantity of reported target information and ensuring that the network side device can accurately understand the measurement. Report. Therefore, in this embodiment of the present application, the overhead of measurement reporting can be reduced.

Optionally, the measurement report associating the information corresponding to the target reference signal can be understood as: the measurement report contains information corresponding to the target reference signal, or there is an association relationship between the measurement report and the information corresponding to the target reference signal. Since the information corresponding to the target reference signal includes information corresponding to reference signals in N1 receiving directions, information corresponding to reference signals in N2 receiving directions, or information corresponding to N3 reference signals, the number of information corresponding to the target reference signal is less than the number of beam information associated with the measurement report configuration.
