Related terms related to the embodiments of the present application are described below.

1. Artificial intelligence

Artificial intelligence is currently in wide-spread use in various fields. There are a number of implementations of 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 FIG. 2.

The neural network is composed of neurons, and a schematic diagram of the neurons is shown in fig. 3. Wherein a is ₁ ,a ₂ ,…a _K For input, w is a weight (multiplicative coefficient), b is a bias (additive coefficient), and σ () is an activation function. Common activation functions include Sigmoid, tanh, reLU (Rectified Linear Unit, linear rectification function, modified linear unit), and the like.

The parameters of the neural network are optimized by an optimization algorithm. An optimization algorithm is a class of algorithms that can help us minimize or maximize an objective function (sometimes called a loss function). Whereas the objective function 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, the predicted output f (X) can be obtained from the input X, and the difference (f (X) -Y) between the predicted and actual values, which is the loss function, can be calculated. Our aim is to find a suitable W, b that minimizes the value of the above-mentioned loss function, the smaller the loss value, the closer our model is to reality.

The most common optimization algorithms are basically based on error back propagation (error Back Propagation, BP) algorithms. The basic idea of the BP algorithm is: the learning process consists of two processes, forward propagation of the signal and reverse propagation of the error. In forward propagation, an input sample is transmitted from an input layer, is processed layer by each hidden layer, and is transmitted to an output layer. If the actual output of the output layer does not match the desired output, the back propagation phase of the error is shifted. The error back transmission is to make the output error pass through hidden layer to input layer in a certain form and to distribute the error to all units of each layer, so as to obtain the error signal of each layer unit, which is used as the basis for correcting the weight of each unit. The process of adjusting the weights of the layers of forward propagation and error back propagation of the signal is performed repeatedly. The constant weight adjustment process is the learning training process of the network. This process is continued until the error in the network output is reduced to an acceptable level or until a preset number of learnings is performed.

Common optimization algorithms are Gradient Descent (Gradient Descent), random Gradient Descent (Stochastic Gradient Descent, SGD), mini-batch Gradient Descent (small lot Gradient Descent), momentum method (Momentum), nestrov (name of the inventor, specifically random Gradient Descent with Momentum), adagard (ADAptive GRADient Descent ), adadelta, RMSprop (root mean square prop, root mean square error Descent), adam (Adaptive Moment Estimation, adaptive Momentum estimation), etc.

When the errors are counter-propagated, the optimization algorithms are all used for obtaining errors/losses according to the loss function, obtaining derivatives/partial derivatives of the current neurons, adding influences such as learning rate, previous gradients/derivatives/partial derivatives and the like to obtain gradients, and transmitting the gradients to the upper layer.

2. Beam indication (beam indication) mechanism

After beam measurement and beam reporting, the network can perform beam indication on the downlink and uplink channels or reference signals, and the beam indication is used for establishing a beam link between the network and User Equipment (UE) so as to realize transmission of the channels or the reference signals.

For beam indication of the physical downlink control channel (Physical Downlink Control Channel, PDCCH), the network configures K transmission configuration indication (Transmission Configuration Indication, TCI) states (states) for each control resource set (CORESET) using radio resource control (Radio Resource Control, RRC) signaling, with 1 TCI state being indicated or activated by the medium access control element (MAC CE) when K >1, and no additional MAC CE commands being required when k=1. When the UE listens to the PDCCH, the same Quasi co-location (QCL), i.e., the same TCI state, is used for all search spaces (search spaces) within the CORESET to listen to the PDCCH. The reference signal (reference signal) in the TCI state, e.g., channel state information reference signal resource (CSI-RS resource), semi-persistent CSI-RS resource, synchronization signal block (SS block), etc.), and the UE-specific PDCCH demodulation reference signal (Demodulation Reference Signal, DMRS) ports are spatial QCL. The UE can learn which reception beam to use to receive the PDCCH according to the TCI state.

For beam indication of physical downlink shared CHannel (Physical Downlink Shared CHANNEL, PDSCH), the network configures M TCI states through RRC signaling, and activates 2 using MAC CE commands ^N The TCI state is then notified by the N-bit TCI field of the DCI, the reference signal in which is QCL with the DMRS port of the PDSCH to be scheduled. The UE can know which reception beam to use to receive PDSCH according to the TCI state.

For beam indication of the CSI-RS, when the CSI-RS type is periodical 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 indicates QCL information thereof when one CSI-RS resource is activated from among RRC configured CSI-RS resource sets through a MAC CE command. When the CSI-RS type is aperiodic CSI-RS, the network configures QCL for CSI-RS resource through RRC signaling and uses DCI to trigger CSI-RS.

For beam indication of PUCCH, the network configures spatial relationship information (spatial relation information) for each PUCCH resource using RRC signaling through the parameter PUCCH-spatial correlation info, and when spatial relation information configured for PUCCH resource contains multiple, one of them spatial relation information is indicated or activated using MAC-CE. When spatial relation information configured for PUCCH resource contains only 1, no additional MAC CE command is required.

For beam indication of PUSCH, the spatial relation information of PUSCH is that when DCI carried by PDCCH schedules PUSCH, each SRI code of SRI field in DCI indicates one SRI, which is used to indicate spatial relation information of PUSCH.

For beam indication of channel sounding reference signals (Sounding Reference Signal, SRS), when the SRS type is periodic SRS, the network configures spatial relation information for SRS resource through RRC signaling. When the SRS type is semi-persistent SRS, the network activates one from the set spatial relation information of RRC configurations through a MAC CE command. When the SRS type is an aperiodic SRS, the network configures spatial relation information for SRS resource through RRC signaling.

For further beam indication improvement, unified TCI indication is proposed, simply by indicating the beam information of the subsequent reference signals and the channels through the TCI field in one DCI.

Note that: the above-mentioned beam information, spatial correlation information, spatial transmission filter (spatial domain transmission filter) information, spatial filter information, TCI state information, QCL parameters, spatial correlation information, beam association relation, and the like are approximately the same meaning. Wherein, the downlink beam information can be generally represented by TCI state information and QCL information; upstream beam information may generally be represented using spatial relationship information.

3. The demodulation sensitivity calculation method comprises the following steps:

receive sensitivity, S (dBm) =thermal noise (dBm) +10log (BW) +nf (dB) +demodulation threshold, where thermal noise-174 dBm/Hz.

Ignoring the demodulation threshold, taking the example of 30ghz,120kh subcarrier spacing (SCS),

base noise on one subcarrier= -174+10 log10 (120 x 10 ³ ) +10= -174+50.8+10= -113.2dBm. The energy of the background noise is already large for high frequency large subcarrier spacing.

4. Beam measurement and reporting (beam measurement and beam reporting)

Analog beamforming is full bandwidth transmission and each polarization-oriented element on the panel of each high frequency antenna array can only transmit analog beams in a time-multiplexed manner. The shaping weight of the analog wave beam is realized by adjusting parameters of equipment such as a radio frequency front-end phase shifter and the like.

At present, in academic circles and industry, training of analog beamforming vectors is generally performed by using a polling mode, that is, array elements in each polarization direction of each antenna panel sequentially transmit training signals (i.e., candidate beamforming vectors) in a time division multiplexing mode at a preset time, and a terminal feeds back a beam report after measurement, so that a network side can adopt the training signals to realize analog beam transmission when transmitting services next time. The content of the beam report typically includes an optimal number of transmit beam identities and measured received power for each transmit beam.

In making beam measurements, the network configures a reference signal resource set (RS resource set) comprising at least one reference signal resource, e.g., SSB resource or CSI-RS resource. The UE measures the layer-one reference signal received power (L1-RSRP)/layer-one signal-to-interference-and-noise ratio (L1-SINR) of each RS resource, and reports the optimal at least one measurement result to the network, wherein the report content comprises a Synchronization Signal Block Rank Indication (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 to use to transmit a channel or signal to the UE.

When the terminal feedback report contains only one L1-RSRP, a 7-bit quantization method is used, the quantization step size is 1dB, and the quantization range is-140 dBm to-44 dBm. When the feedback report that the terminal is instructed contains a plurality of L1-RSRP, or group based beam report is enabled, 7bit quantization is used for the strongest RSRP quantization, and a 4bit differential quantization method is used for the rest of RSRP quantization, with a quantization step size of 2dB.

5. Beam prediction using AI method:

one possible approach is shown in fig. 4, using the RSRP of a partial beam pair as input, and the output of the AI model is the RSRP result of all beam pairs. Wherein the beam pair is composed of a transmit beam and a receive beam. The input number of the AI model is the number of the selected partial beam pairs, and the output number is the number of all beam pairs.

As shown in fig. 5, there is an additional method for enhancing the beam prediction performance, in which association information is added to the input side, and the association information is generally angle-related information, beam ID information, etc. corresponding to the beam pair selected for input. The number of inputs to such a model is therefore also related to the number of partial beam pairs that are picked up, and the number of outputs is also equal to the number of all beam pairs.

Still another approach based on the above improvement is to influence the output of the AI model, mainly by changing the desired information by the AI model, as shown in fig. 6.

Wherein the input type of the AI model includes at least one of:

beam quality related information;

association information about the beam;

the A end sends the association information related to the wave beam;

the B-side receives the association information related to the wave beam;

the association information of the beam expected by the B end;

the expected B-end receives the association information related to the wave beam;

the A terminal expected by the B terminal sends the association information related to the wave beam;

time-related information related to beam quality-related information;

expected predicted time related information.

The association information related to the beam refers to association information corresponding to the beam, and the association 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, and the like.

The beam ID related information is related information for characterizing the identity of the beam, including but not limited to at least one of: the method comprises the steps of sending a beam ID, receiving the beam ID, a reference signal set ID corresponding to the beam, a reference signal resource ID corresponding to the beam, a random ID of a unique identifier, a coded value processed by an additional AI network, beam angle related information and the like.

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

The angle-related information is related information for characterizing an angle, such as an angle, radian, index code value, code value after additional AI network processing, and the like.

The information transmission method, the information transmission device, the terminal and the network side equipment provided by the embodiment of the application are described in detail through some embodiments and application scenes thereof by combining the attached drawings.

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

step 701, a terminal sends a feedback report to a network side device, wherein the feedback report is used for feeding back a measurement result obtained by measuring a reference signal;

The measurement in the embodiment of the present application may include beam measurement, where the reference signal is transmitted through a spatial filter, and in the embodiment of the present application, the measurement on the reference signal may be understood as measurement on the spatial filter, and may also be understood as measurement on beam resources. The feedback report in embodiments of the present application may also be referred to as a measurement report, which may include a beam measurement report.

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

Wherein the measurement results satisfy at least one of:

a11, the measurement result meets a target threshold;

optionally, the target gate includes at least one of:

a111, the first threshold value is larger than and/or equal to a first threshold value, wherein the first threshold value is a dynamic lower limit value of a screening measurement result;

a112, the value is smaller than and/or equal to a second threshold value, wherein the second threshold value is a dynamic upper limit value of screening measurement results;

the first threshold value is smaller than the second threshold value.

A113, the value is smaller than and/or equal to a threshold upper limit value, and the threshold upper limit value screens a fixed upper limit value of a measurement result;

a114, the threshold upper limit value is larger than and/or equal to the threshold lower limit value, and the fixed lower limit value of the measurement result is screened by the threshold upper limit value;

It will be appreciated that the upper and lower thresholds are protocol-agreed thresholds, and the first and second thresholds are additionally configured dynamic thresholds, where the first threshold may be considered as an additionally configured lower threshold for screening measurements, and the second threshold may be considered as an additionally configured upper threshold for screening measurements, where the upper and/or lower thresholds are typically employed for screening measurements if the first and/or second thresholds are not configured.

Optionally, when only the first threshold value is additionally configured, the screening range is determined by the first threshold value and the upper threshold value, when only the second threshold value is additionally configured, the screening range is determined by the second threshold value and the lower threshold value, and when the first threshold value and the second threshold value are additionally configured at the same time, the screening 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 a protocol convention, a network side device configuration or a terminal determination manner. The protocol convention may 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, and do not need to interact with each other. The network side equipment configuration can be understood as that the network side equipment determines a first threshold value and a second threshold value based on the report of the terminal, the recommendation of the terminal or the AI model capability, and notifies the terminal. The terminal determination may be understood as a first threshold value, a second threshold value, used by the terminal based on a noise floor or AI model capability determination determined by the hardware demodulation capability.

Optionally, when the network side device configures a plurality of first threshold values and/or second threshold values for the terminal, the terminal may select to use a specific threshold value based on its own situation, in which case, the terminal may need to report the used first threshold value and/or second threshold value to the network side device. Optionally, when the first threshold value and/or the second threshold value are determined by the terminal, the terminal may also need to report the used first threshold value and/or second threshold value 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 first threshold value and/or the second threshold value is directly included in the feedback report, or the first threshold value and/or the second threshold value is indicated by configuration information of the feedback report.

For example, the terminal recommends 1 threshold value or indicates multiple threshold values when reporting the terminal capability, and the network configures the first threshold value according to the information of the terminal recommendation or the UE capability reporting.

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, interaction of the capability of the AI model for beam prediction between the terminal and the network side device may be required, e.g., a limitation of the minimum RSRP value input by the interaction AI model or a limitation of the maximum RSRP value input by the interaction model.

It should be noted that, by using the target gate to screen the measurement results, only the measurement results meeting the requirement of the target gate are fed back, so as to control the number of the fed back measurement results, and reduce the feedback overhead.

A12, obtaining the measurement result based on target information quantization;

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

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

It will be appreciated that the upper and lower threshold values are the thresholds of the quantization interval agreed by the protocol, while the third and fourth threshold values are thresholds of the quantization interval configured additionally, the third threshold value may be regarded as the lower limit value of the quantization configured additionally, and the fourth threshold value may be regarded as the upper limit value of the quantization configured additionally.

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

Case one, 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 upper threshold 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, and when both the third threshold value and the fourth threshold value are additionally configured, the quantization interval is determined by the third threshold value and the fourth threshold value.

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

Optionally, the third threshold value and the fourth threshold value may be indicated by a protocol convention, a network side device configuration or a terminal determining manner.

Optionally, when the third threshold value and/or the fourth threshold value are determined by the terminal, the terminal may also need to report the used third threshold value and/or fourth threshold value 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 third threshold value and/or the fourth threshold value is directly included in the feedback report, or the third threshold value and/or the fourth threshold value is indicated by configuration information of the feedback report.

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

protocol conventions, network side equipment configuration, terminal determination.

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

Case two, the target information includes a first reference value

Optionally, the first reference value is determined from the measurement result. One way of understanding is: the first reference value is included in the measurement results, i.e. the first reference value is one of the measurement results, for example comprising the following 5 measurement results, respectively: -40dBm, -60dBm, -70dBm, -65dBm, -100dBm, the first reference value being-70 dBm, or the first reference value being a median value of 5 measurements, i.e. -65dBm; another way of understanding is: the first reference value is determined by calculation from the measurement results, that is, the first reference value is not included in the measurement results, for example, the first reference value is an average value of the measurement results, and may also be a median value, for example, including the following 4 measurement results respectively: -40dBm, -60dBm, -80dBm, -100dBm, the first reference value being-70 dBm when the first reference value is the average value of the measurement results, and-70 dBm when the first reference value is the median value of the measurement results.

Optionally, the manner in which the measurement results determine the first reference value is indicated by one of:

For example, the protocol agrees that the first reference value is the measurement result with the largest value in the measurement results; for example, the network side device configures the first reference value as a mean value of the measurement results; for example, the terminal itself determines the first reference value as the median value in the measurement result.

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

Optionally, in the case that the measurement result meets the target threshold, the determining manner of the measurement result includes one of the following:

b11, the terminal determines a measurement result meeting a target threshold from measurement values obtained by measuring the reference signals;

it should be noted that, in this case, the determination of the measurement result is directly performed based on the measurement value.

B12, the terminal quantifies a measured value obtained by measuring the reference signal, and a measured result meeting the target threshold is determined in the quantified measured value;

In this case, the measured value is quantized based on the target gate, and then the measurement result satisfying the target gate is determined from the quantized measured value.

It should be further noted that, if the terminal needs to send multiple feedback reports, the network may configure a threshold (e.g., a first threshold) for each feedback report, where each feedback uses its own threshold; it is also possible that the terminal configures one threshold (e.g. the first threshold) and the same threshold is used for multiple feedback reports.

Optionally, in another embodiment of the present application, in a case that the measurement result meets the target threshold, the quantization 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 result according to the target gate, the measurement result needs to be quantized before the measurement result is fed back, and the final quantized result is fed back to the network side device.

Optionally, the bit overhead of the measurement quantization is determined by a quantization interval of the measurement. The quantization step size of the measurement result quantization can be determined by protocol convention, network side equipment configuration or terminal.

For example, if the quantization interval is determined to be [ -100dBm, -60dBm ] by the upper threshold limit and the lower threshold limit agreed by the protocol, in the case that the quantization step size agreed by the protocol is 1dBm, the number of bits occupied after each measurement result is quantized is 6.

For example, the terminal measures multiple beam resources to obtain 4L 1-RSRP, which are respectively-130.4 dBm, -128.9dBm, -145.1dBm, -66.2dBm, and the first threshold is-130 dBm, a) if the terminal determines whether the measured value is greater than or equal to the threshold value, only 2 measurement results are needed to be fed back, which are respectively-128.9 dBm and-66.2 dBm, and quantization is performed after determining the feedback object; b) If the measurement result can be quantized, that is, it means that quantization can be performed first and then whether the value is greater than or equal to the threshold value is determined, the quantized 4 values are equivalent to-130 dBm, -128dBm, -145dBm and-66 dBm respectively, so that 3 measurement results are required to be fed back, namely-130 dBm, -128dBm and-66 dBm respectively.

Optionally, in another embodiment of the present application, in a 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, 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.

In this case, the first reference value needs to be quantized, where the quantization interval of the first reference value may be determined by at least two of the third threshold value, the fourth threshold value, the upper threshold value, and the lower threshold value, and 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:

For example: the lower limit value of the protocol contract threshold is-140 dBm for L1-RSRP, and the upper limit value of the protocol contract threshold is-44 dBm for L1-RSRP.

For example: the third threshold value is-70 dBm, the upper limit value of protocol convention is-44 dBm, the dynamic quantization interval is [ -70dBm, -44dBm ], the dynamic quantization cost of the first reference value is the upward rounding result of log2 ((70-44)/quantization step size), wherein the quantization step size is equal to 1dB, and the dynamic quantization cost is equal to 5 bits.

Optionally, the quantization mode of the other measurement results except the first reference value 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 the other measurement results than the first reference value among the measurement results may be protocol conventions, network side device configurations, or terminal determination.

Alternatively, in one case, the first quantization step size is equal to the second quantization step size, that is, the first reference value and quantization of other measurement results except the first reference value in the measurement results use the same quantization step size, which is understood that no additional quantization step size is required.

In another case, the first quantization step size is not equal to the second quantization step size, and the first quantization step size and/or the second quantization step size are associated in the feedback report. Further, in the case that one of the first quantization step size and the second quantization step size is associated in the feedback report, the other one of the first quantization step size and the second quantization step size is agreed by a protocol. That is, in this case, one of the first quantization step size and the second quantization step size needs to be additionally configured, and the terminal must feed back the additionally configured quantization step size to the network-side device when feeding back.

Optionally, if the feedback report includes the second quantization step size, for example, the feedback report includes 1bit step size indication information, for indicating whether the step size is 2dB or 3dB, or for indicating whether the step size is 3dB or 4dB; for example, the feedback report contains 2bit step size indication information for indicating that the step size 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 needs to feed back the first reference value to the network side device, and the terminal generally feeds back the first reference value to the network side device by associating the first reference value with the feedback report.

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

c11, the first reference value is included in the feedback report; or alternatively

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 needs to be quantized, the feedback value of the other measurement results is determined by performing differential quantization on the measurement results and the first reference value.

Optionally, in another embodiment of the present application, in a case where 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 the third threshold value, the fourth threshold value, the upper threshold value, and the lower threshold value.

In this case, the first reference value is used to determine the quantization interval. Alternatively, the quantization step size of the measurement result may be determined by a protocol convention, a network side device configuration, or a terminal.

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

That is, in this case the target gate is used in combination with the first reference value to finally enable 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, taking the first threshold value being equal to the first reference value as an example, an alternative implementation manner in one case is that the terminal screens the measured value based on the first reference value to obtain a measured result greater than or equal to the first reference value, and then quantizes the measured result by taking the first reference value and a fourth threshold value (i.e., an additionally configured upper limit value) as quantization intervals, where a quantization step size is agreed by a protocol. In another alternative implementation manner, the terminal screens the measured value based on the first reference value to obtain a measured result greater than or equal to the first reference value, quantizes a quantization interval determined by the first reference value based on a threshold upper limit value and a threshold lower limit value agreed by a protocol, and differentially quantizes other measured results in the measured result and the first reference value, wherein a quantization step length of differential quantization is configured by the network side device.

Optionally, in an embodiment of the present application, the measurement result includes at least one of:

layer one signal-to-interference-plus-noise ratio (L1-SINR), layer one reference signal received power (L1-RSRP), layer one reference signal received quality (L1-RSRQ), layer three signal-to-interference-plus-noise ratio (L3-SINR), layer three reference signal received power (L3-RSRP), layer three reference signal received quality (L3-RSRQ).

It should be noted that, the feedback report mentioned in the embodiments of the present application may also be referred to as a measurement report, and the measurement report in the embodiments of the present application may include a beam measurement report.

It should be noted that, in at least one embodiment of the present application, by sending, to the network side device, a feedback report for feeding back the measurement result that meets the target gate and/or is quantized based on the target information, the indication of the quantization interval can be dynamically performed, so that the feedback overhead of the measurement result can be reduced.
