The relevant terms involved in the embodiments of this application are described below.

1. Artificial intelligence

Artificial intelligence is currently widely used in various fields. There are many ways to implement AI networks, such as neural networks, decision trees, support vector machines, Bayesian classifiers, etc. For example, a schematic diagram of a neural network is shown in Figure 2.

Among them, the neural network is composed of neurons, and the schematic diagram of the neurons is shown in Figure 3. Among them, a ₁ , a ₂ ,...a _K is the input, w is the weight (multiplicative coefficient), b is the bias (additive coefficient), and σ(.) is the activation function. Common activation functions include Sigmoid, tanh, linear rectification 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 the values (f(x)-Y), this is the loss function. Our purpose is to find the 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 backpropagate the output error in some form to the input layer layer by layer through the hidden layer, and allocate the error to all units in each layer, thereby obtaining the error signal of each layer unit. 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 of the network. process. 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 (Nesterov) , adaptive gradient descent (ADAptive GRADient descent, Adagrad), adaptive increment (Adadelta), root mean square error reduction (root mean square prop, RMSprop), adaptive momentum estimation (Adaptive Moment Estimation, Adam), etc.

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. About the beam indication mechanism

After beam measurement and beam reporting, the network can perform beam indication on the downlink and uplink channels or reference signals, which is used to establish beam links between the network and user equipment (User Equipment, UE) to implement channel or reference signals. transmission.

For the beam indication of the physical downlink control channel (Physical Downlink Control Channel, PDCCH), the network uses Radio Resource Control (Radio Resource Control, RRC) signaling to configure K transmission configuration indications for each control resource set (Control Resource Set, CORESET) (Transmission Configuration Indication, TCI) state (state), when K>1, a TCI state is indicated or activated by the media access control control unit (:Media Access Control Control Element, MAC CE). When K=1, No additional MAC CE commands are required. When the UE 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 in the TCI state (referenceSignal, such as Channel State Information Reference Signal resource (CSI-RS resource), semi-persistent CSI-RS resource, synchronization signal block (Synchronization Signal block, SSB), etc.) It is spatial QCL with the UE-specific PDCCH Demodulation Reference Signal (DMRS) port. The UE can learn which receiving beam is used to receive the PDCCH according to the TCI status.

For the beam indication of the physical downlink shared channel (Physical Downlink Shared CHannel, PDSCH), the network 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, DCI ) of the N-bit TCI field to notify the TCI status. The referenceSignal 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 CSI-RS beam indication, when the CSI-RS type is periodic CSI-RS, the network configures QCL information for the CSI-RS resource through RRC signaling. When the CSI-RS type is semi-persistent CSI-RS, the network 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 configures QCL for the CSI-RS resource through RRC signaling, and Use DCI to trigger CSI-RS.

For the beam indication of the Physical Uplink Control Channel (PUCCH), the network uses RRC signaling to configure spatial relationship information (spatial relation information) for each PUCCH resource through the parameter PUCCH-SpatialRelationInfo. When configured for the PUCCH resource When spatial relation information contains multiple spatial relation information, use MAC-CE to indicate or activate one of the spatial relation information. When the spatial relation information configured for the PUCCH resource only contains 1, no additional MAC CE command is required.

For the beam indication of PUSCH, the spatial relation information of PUSCH is when the DCI carried by the PDCCH schedules the PUSCH, each of the channel sounding reference signal (Sounding Reference Signal, SRS) resource indication (SRS Resource Indicator, SRI) field (field) in the DCI Each SRI codepoint indicates an SRI, which is used to indicate the spatial relation information of PUSCH.

For the beam indication of the channel sounding reference signal (Sounding Reference Signal, SRS), when the SRS type is periodic SRS, the network configures spatial relation information for the SRS resource through RRC signaling. When the SRS type is semi-persistent SRS, the network 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 configures spatial relation information for the SRS resource through RRC signaling.

For further improvement of beam 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.

Note: The beam information, spatial relation information, spatial domain transmission filter information, spatial filter information, TCI state information, QCL information, QCL parameters, spatial relation information, and beam correlation mentioned above 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 represented by spatial relation information.

3. Demodulation sensitivity calculation method:

Receiving sensitivity, S (dBm) = thermal noise (dBm) + 10log (BW) + NF (dB) + demodulation threshold, where the thermal noise is -174dbm/Hz.

Ignoring the demodulation threshold, taking 30GHz, 120kHz sub-carrier space (SCS) as an example,

The noise floor on one subcarrier=-174+10*log10(120*103)+10=-174+50.8+10=-113.2dBm. Therefore, for high-frequency large sub-carrier spacing, the energy of the noise floor is already large.

4. 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 ( i.e. candidate Shaping vector), the terminal feeds back the beam report after measurement, so that the network side 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 doing beam measurements, the network will configure a reference signal resource set (RS resource set), which includes at least one reference signal resource, such as a synchronization signal block resource (Synchronization Signal Block resource, SSB resource) or channel status Information reference signal resource (Channel State Information Reference Signal resource, CSI-RS resource). The UE measures the Layer 1 Reference Signal Receiving Power (L1-RSRP)/Layer 1 Signal to Interference plus Noise Ratio (L1-SINR) of each RS resource, and compares the optimal at least one The measurement results are reported to the network, and the reported content includes synchronization signal block rank indicator (SSB 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 to determine the beam used to send channels or signals to the UE.

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 feedback report instructed by the terminal 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 a 4-bit differential quantization method with a quantization step of 2dB.

5. Use AI methods for beam prediction:

One possible method is shown in Figure 4, using the RSRP of some beam pairs as input, and the output of the AI model is the RSRP result of all beam pairs. 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.

In addition, there are methods to enhance the beam prediction performance, as shown in Figure 5. Related information is added to the input side. The related information is generally angle-related information corresponding to the beam pairs selected for input, beam identification (Identity, ID) information, etc. . Therefore, the number of inputs of 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 6, which mainly changes the expected information through the AI model to affect the output of the AI model.

The input type of the AI model includes at least one of the following:

Beam quality related information;

Beam-related associated information;

The A-side sends beam-related association information;

Relevant information related to the B-side receiving beam;

Related information related to the beam expected by the B-side;

The associated information related to the B-side receiving beam expected by the B-side;

End B expects end A to send beam-related associated 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.

Beam ID related information is used to characterize the relevant information of the identity of the beam, including but not limited to at least one of the following: transmitting beam ID, receiving beam ID, beam ID, reference signal set ID corresponding to the beam, the beam Corresponding reference signal resource ID, uniquely identified random ID, coded value after additional AI network processing, beam angle related information, etc.

The beam angle related information is used to represent the angle related information corresponding to the beam, including but not limited to at least one of the following: angle related information, sending angle related information, and receiving angle related information.

Angle-related information is related information used to characterize angles, such as angles, radians, index code values, code values processed by additional AI networks, etc.

The information transmission method, device, terminal and network-side equipment provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through some embodiments and application scenarios.

As shown in Figure 7, this embodiment of the present application provides an information transmission method, including:

Step 701: The terminal sends a feedback report to the network side device, where the feedback report is used to feed back the measurement results obtained by measuring the reference signal;

The measurement in the embodiment of the present application may include beam measurement, and the reference signal is transmitted through the spatial filter. The measurement of the reference signal in the embodiment of the present application may be understood as measuring the spatial filter, or it may be understood as It is to measure the beam resources. The feedback report in the embodiment of the present application may also be called a measurement report, and the measurement report may include a beam measurement report.

The measurement results in this embodiment of the present application may include beam measurement results.

Wherein, the measurement results satisfy at least one of the following:

A11. The measurement results meet the target threshold;

Optionally, the target threshold includes at least one of the following:

A111, greater than and/or equal to the first threshold value, the first threshold value is the dynamic lower limit value for screening measurement results;

A112, less than and/or equal to the second threshold, the second threshold being the dynamic upper limit for filtering measurement results;

It should be noted that the first threshold value is smaller than the second threshold value.

A113, less than and/or equal to the upper threshold value, which filters the fixed upper limit value of the measurement results;

A114, greater than and/or equal to the lower threshold value, the upper threshold value filters the fixed lower limit value of the measurement results;

It can be understood that the upper threshold value and the lower threshold value are the thresholds agreed upon by the protocol, and the first threshold value and the second threshold value are additionally configured dynamic thresholds. The first threshold value can be regarded as The lower limit value and the second threshold value of the additionally configured filtering measurement results can be regarded as the upper limit value of the additionally configured filtering measurement results. Normally, if the first threshold value and/or the second threshold value are not configured value, use the upper threshold value and/or the lower threshold value to filter the measurement results.

Optionally, when only the first threshold value is additionally configured, the filtering range is determined by the first threshold value and the threshold upper limit value; when only the second threshold value is additionally configured, the filtering range is determined by the second threshold value and The lower threshold value is determined. When an additional A threshold value and a second threshold value, the filtering range is determined by the first threshold value and the second threshold value.

Optionally, the first threshold value and the second threshold value may be indicated by protocol agreement, network side device configuration, or terminal determination. The protocol stipulation can be understood that the first threshold value and the second threshold value are defined in the protocol and are known by both the terminal and the network side device, without the need for interaction between the two. The network side device configuration can be understood as the network side device determining the first threshold value and the second threshold value based on the terminal's report, the terminal's recommendation or the AI model capability, and notifying the terminal. The terminal determination can be understood as the terminal determining the first threshold value and the second threshold value based on the noise floor or AI model capability determined by the hardware demodulation capability.

Optionally, when the network side device configures multiple first thresholds and/or second thresholds for the terminal, the terminal can choose to use a specific threshold based on its own situation. In this case, the terminal The used first threshold value and/or second threshold value may need to be reported to the network side device. Optionally, when the first threshold and/or the second threshold are determined by the terminal, the terminal may also need to report the used first threshold and/or the second threshold to the network side device. Optionally, the terminal may associate the first threshold value and/or the second threshold value in the feedback report. For example, the feedback report directly includes the first threshold value and/or the second threshold value, or the first threshold value and/or the second threshold value are directly included in the feedback report. A threshold value and/or a second threshold value are indicated by the configuration information of the feedback report.

For example, the terminal recommends one threshold value or indicates multiple threshold values when reporting the terminal capability. The network configures the first threshold value based on the information recommended by the terminal or reported by the UE capability.

For example, when the terminal or the network side device determines the first threshold value and/or the second threshold value based on the AI model capability, the terminal and the network side device may need to interact with the AI model capability for beam prediction. For example, the limit of the minimum RSRP value of the interactive AI model input, or the limit of the maximum RSRP value of the interactive model input.

It should be noted that by using the target threshold to filter the measurement results and only feeding back the measurement results that meet the target threshold requirements, thereby controlling the number of feedback measurement results, the feedback overhead can be reduced.

A12. The measurement results are quantitatively obtained based on the target information;

Optionally, the target information includes: at least two of the first reference value, the third threshold value, the fourth threshold value, the upper threshold value and the lower threshold value;

It should be noted that the third threshold is smaller than the fourth threshold, the third threshold is the dynamic lower limit of the quantization interval, and the fourth threshold is the dynamic upper limit of the quantization interval.

It can be understood that the upper threshold value and the lower threshold value are the thresholds of the quantization interval stipulated in the agreement, and the third threshold value and the fourth threshold value are the thresholds of the additionally configured quantization interval. The third threshold value The value can be regarded as the lower limit value of additionally configured quantization, and the fourth threshold value can be regarded as the upper limit value of additionally configured quantization.

The following describes respectively the cases where the target information includes the first reference value and the case where the target information does not include the first reference value.

Case 1: The target information does not include the first reference value

In this case, when only the third threshold value is additionally configured, the quantization interval is determined by the third threshold value and the threshold upper limit value. When only the fourth threshold value is additionally configured, the quantization interval is determined by the fourth threshold value. and the lower threshold value are determined. When a third threshold value and a fourth threshold value are additionally configured at the same time, the quantization interval is determined by the third threshold value and the fourth threshold value.

Optionally, in one case, the third threshold value may also be equal to the first threshold value, and the fourth threshold value may also be equal to the second threshold value.

Optionally, the third threshold value and the fourth threshold value may be indicated by protocol agreement, network side device configuration, or terminal determination.

Optionally, when the third threshold and/or the fourth threshold are determined by the terminal, the terminal may also need to report the used third threshold and/or the fourth threshold to the network side device. Optionally, the terminal may associate the third threshold value and/or the fourth threshold value in the feedback report. For example, the feedback report directly includes the third threshold value and/or the fourth threshold value, or the third threshold value is directly included in the feedback report. The third threshold value and/or the fourth threshold value is indicated by the configuration information of the feedback report.

Optionally, in this case, the quantization step size of the measurement result is determined by at least one of the following:

Agreement agreement, network side device configuration, terminal determination.

It should be noted that by quantizing the measurement results based on the determined quantization interval, the number of feedback bits of the measurement results can be controlled, thereby reducing the feedback overhead.

Case 2: The target information includes the first reference value

Optionally, the first reference value is determined from measurement results. One way to understand it is: the first reference value is included in the measurement results, that is, the first reference value is one of the measurement results. For example, it includes the following 5 measurement results, which are: -40dBm, -60dbm, -70dBm, -65dBm. , -100dBm, the first reference value is -70dBm, or the first reference value is the median value among the 5 measurement results, that is, -65dBm; another way to understand it is: the first reference value is calculated from the measurement results Determine, that is, the first reference value is not included in the measurement results. For example, the first reference value is the average value of the measurement results, or it can be the median value. For example, it includes the following 4 measurement results, respectively: -40dBm, -60dBm, -80dBm, -100dBm. When the first reference value is the average value of the measurement results, the first reference value is -70dBm. When the first reference value is the median value of the measurement results, the first reference value is -70dBm. The first reference value is -70dBm.

Optionally, the manner in which the measurement result determines the first reference value is indicated by one of the following:

Agreement agreement, network side device configuration, terminal determination.

For example, the protocol stipulates that the first reference value is the measurement result with the largest value among the measurement results; for example, the network side device configures the first reference value to be the average of the measurement results; for example, the terminal determines that the first reference value is the average value among the measurement results. median value.

It should be noted that by quantizing the measurement result based on at least the first reference value, the number of feedback bits of the measurement result can be controlled, and the dynamic range of quantization can also be improved.

Optionally, when the measurement result meets the target threshold, the determination method of the measurement result includes one of the following:

B11. The terminal determines the measurement result that meets the target threshold among the measurement values obtained by measuring the reference signal;

It should be noted that in this case, the measurement results are determined directly based on the measured values.

B12. The terminal quantifies the measurement value obtained by measuring the reference signal, and determines the measurement result that meets the target threshold from the quantized measurement value;

It should be noted that in this case, the measurement values are quantified based on the target threshold, and then the measurement results that meet the target threshold are determined from the quantized measurement values.

It should also be noted that if the terminal needs to send multiple feedback reports, the network can configure a threshold value (for example, the first threshold value) for each feedback report, and each feedback uses its own threshold value; it can also The terminal configures a threshold value (for example, the first threshold value), and multiple feedback reports use the same threshold value.

Optionally, in another embodiment of the present application, when the measurement result meets the target threshold, the quantification interval of the measurement result is determined by at least one of the following:

The first threshold value, the second threshold value, the upper threshold value, and the lower threshold value.

It should be noted that after determining the measurement results according to the target threshold, the measurement results need to be quantified before feeding back the measurement results, and the final quantified results are fed back to the network side device.

Optionally, the bit overhead of quantizing the measurement result is determined by the quantization interval of the measurement result. The quantization step size for quantification of measurement results can be determined by protocol agreement, network side device configuration, or terminal.

For example, if the quantization interval is determined as [-100dBm, -60dBm] by the upper threshold value and lower threshold value agreed in the agreement, and the quantization step size agreed in the agreement is 1dBm, each measurement result will be occupied by the quantized The number of bits is 6.

For example, the terminal measures multiple beam resources and obtains 4 L1-RSRPs, which are -130.4dBm, -128.9dBm, -145.1dBm, and -66.2dBm. The first threshold is -130dBm. a) If the terminal first determines whether it is greater than or is equal to the threshold value, then only two measurement results need to be fed back, namely -128.9dBm and -66.2dBm. The feedback objects can be determined before quantization; b) If the above measurement results can be quantized, it means that quantification can be performed first. Then determine whether it is greater than or equal to the threshold value, then the four quantized values are equivalent to -130dBm, -128dBm, -145dBm, and -66dBm, so three measurement results need to be fed back, which are -130dBm, -128dBm, and -66dBm.

Optionally, in another embodiment of the present application, in the case where the target information includes a first reference value, if the measurement result includes the first reference value, or if the measurement result does not include the first reference value, Reference value, the quantization interval of the first reference value is determined by at least two of the following:

The third threshold value, the fourth threshold value, the upper threshold value and the lower threshold value.

It should be noted that in this case, the first reference value needs to be quantized, and the quantization interval of the first reference value can be composed of a third threshold value, a fourth threshold value, an upper threshold value, and a lower threshold value. At least two of them determine that the quantization step size of the first reference value is the first quantization step size. Optionally, the first quantization step size is determined by at least one of the following:

Agreement agreement, network side device configuration, terminal determination.

For example: the lower threshold value agreed in the agreement is -140dBm for L1-RSRP, and the upper limit value agreed in the agreement is -44dBm for L1-RSRP.

For example: the third threshold is -70dBm, the upper limit agreed upon by the protocol is -44dBm, the dynamic quantization interval is [-70dBm,-44dBm], and the dynamic quantization overhead of the first reference value is log2((70-44 )/quantization step), where the quantization step is equal to 1dB, so the dynamic quantization overhead is equal to 5 bits.

Optionally, the quantization method of the measurement results other than the first reference value in the measurement results is determined by the first reference value, the quantized bit overhead, and the second quantization step size.

In this case, the quantized bit overhead of other measurement results in the measurement results except the first reference value can be It is determined by protocol agreement, network side device configuration or terminal.

Optionally, in one case, the first quantization step size is equal to the second quantization step size, that is, the first reference value and other measurement results in the measurement results except the first reference value are quantized using the same method. Quantization step size, at this time it can be understood that there is no need to configure additional quantization step size.

In another case, the first quantization step size is not equal to the second quantization step size, and the feedback report is associated with the first quantization step size and/or the second quantization step size. Further, in the case where one of the first quantization step size and the second quantization step size is associated in the feedback report, the first quantization step size and the second quantization step size are The other is stipulated in the agreement. That is to say, in this case, one of the first quantization step size and the second quantization step size needs to be additionally configured, and when the terminal performs feedback, it must feed back the additionally configured quantization step size to the network. side equipment.

Optionally, if the feedback report contains the second quantization step size, for example, the feedback report contains 1-bit step size indication information, used to indicate whether the step size is 2dB or 3dB, or used to indicate the step size of 3dB or 4dB; for example, the feedback report The report contains 2-bit step indication information, which is used to indicate whether the step is 1dB, 2dB, 3dB or 4dB.

It should be further noted that if the measurement result does not include the first reference value, the terminal side also needs to feed back the first reference value to the network side device. The terminal usually adopts the method described in the feedback report association. The first reference value is fed back to the network side device in the form of the first reference value.

Optionally, the feedback report is associated with the first reference value, which can be understood as one of the following:

C11. The first reference value is included in the feedback report; or

C12. The first reference value is indicated by the configuration information of the feedback report.

It should be noted that when the first reference value also needs to be quantized, the feedback values of other measurement results are determined by differential quantization of the measurement results and the first reference value.

Optionally, in another embodiment of the present application, when the target information includes a first reference value, the quantization interval of the measurement result is determined based on the first reference value and the first information;

Wherein, the first information includes: one of a third threshold value, a fourth threshold value, an upper threshold value and a lower threshold value.

It should be noted that in this case, the first reference value is used to determine the quantization interval. Optionally, the quantization step size of the measurement result may be determined by protocol agreement, network side device configuration, or terminal.

Optionally, in another embodiment of the present application, when the target threshold includes: greater than and/or equal to the first threshold value, or less than and/or equal to the second threshold value, the first The reference value is determined by the first threshold value or the second threshold value.

That is to say, in this case, the target threshold is used in combination with the first reference value to finally realize the sending of the feedback report. Optionally, the first reference value is equal to the first threshold value or the second threshold value.

For example, assuming that the first threshold value is equal to the first reference value, an optional implementation method in one case is that the terminal first filters the measurement values based on the first reference value to obtain measurement results that are greater than or equal to the first reference value. , and then use the first reference value and the fourth threshold value (that is, the additionally configured upper limit value) as the quantization interval to quantify the measurement results, where the quantization step The length is determined by the agreement. An optional implementation method in another case is that the terminal first filters the measurement values based on the first reference value to obtain measurement results that are greater than or equal to the first reference value, and then filters the first reference value based on the upper threshold agreed upon in the protocol. Quantization is performed within a quantization interval determined by the lower threshold value, and other measurement results in the measurement results are differentially quantized with the first reference value, where the quantization step size of the differential quantification is configured by the network side device.

Optionally, in an embodiment of the present application, the measurement results include at least one of the following:
