For ease of understanding, some of the matters 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 various implementations of AI modules, such as neural networks, decision trees, support vector machines, bayesian classifiers, etc. The present application is described with reference to neural networks, but is not limited to a particular type of AI module.

The neural network is composed of neurons, and a schematic diagram of the neurons is shown in fig. 2. Wherein z=a ₁ *w ₁ +···+a ₁ *w ₁ +···+a _k *w _k +b，a 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, hyperbolic tangent (tanh), linear rectifying function ReLU (Rectified 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 value and the true value, 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 that the learning process consists of two processes, forward propagation of the signal and backward 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), random Gradient Descent with Momentum (also known as Nesterov), adaptive Gradient Descent (ADAptive GRADient Descent, adagrad), adadelta, root mean square error Descent (root mean square prop, RMSprop) and adaptive Momentum estimation (Adaptive Moment Estimation, adam).

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. With respect to beam indication (beam indication) mechanisms.

After beam measurement and beam report, the network side device can perform beam indication on the downlink and uplink channels or reference signals, and is used for establishing a beam link between the network side device and the terminal, so as to realize the transmission of the channels or the reference signals.

For beam indication of the physical downlink control channel (Physical downlink control channel, PDCCH), the network side device configures K transmission configuration indications (Transmission Configuration Indication, TCI) states (states) for each control resource set (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 unit (Medium Access Control Control Element, MAC CE) when K >1, and no additional MAC CE commands being required when k=1. When the terminal listens to the PDCCH, the same Quasi co-location (QCL), i.e. the same TCI state, is used for listening to the PDCCH for all search spaces (search spaces) in the CORESET. The Reference Signal (Reference Signal) and terminal-specific (UE-specific) PDCCH demodulation Reference Signal (Demodulation Reference Signal, DMRS) ports in this TCI state are spatial QCL. The terminal can know which reception beam to use to receive the PDCCH according to the TCI state. The reference signals in the TCI state may be periodic channel state reference signals (Channel State Information Reference Signal, CSI-RS), semi-persistent CSI-RS, and synchronization signal blocks (Synchronization Signal and PBCH block, SSB), etc.

For beam indication of the physical downlink shared channel (Physical downlink shared channel, PDSCH), the network side device configures M TCI states through RRC signaling, then activates 2N TCI states using MAC CE commands, and then informs the TCI state through the N-bit TCI field (field) of the downlink control information (Downlink Control Information, DCI), the reference Signal in the TCI state 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 periodic CSI-RS, the network side device configures QCL information for CSI-RS resources (resource) through RRC signaling. When the CSI-RS type is semi-persistent CSI-RS, the network side equipment indicates QCL information of one CSI-RS resource set (resource set) configured by RRC through a MAC CE command when the one CSI-RS resource set is activated. When the CSI-RS type is aperiodic CSI-RS, the network side equipment configures QCL for the CSI-RS resource through RRC signaling, and uses DCI to trigger the CSI-RS.

For beam indication of a physical uplink control channel (Physical Uplink Control Channel, PUCCH), the network side device configures spatial relationship information (spatial relation information) for each PUCCH resource using RRC signaling through a parameter PUCCH-spacialrelation info, and when spatial relation information configured for PUCCH resource contains a plurality of, uses MAC-CE to indicate or activate one spatial relation information. When spatial relation information configured for PUCCH resource contains only 1, no additional MAC CE command is required.

For beam indication of a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), the spatial relation information of the PUSCH is that when the DCI carried by the PDCCH schedules the PUSCH, each SRI code point (code point) of a sounding reference signal resource indication (Sounding Reference Signal resource indicator, SRI) field in the DCI indicates one SRI for indicating spatial relation information of the PUSCH.

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

For further beam indication improvement, a unified TCI indication (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.

Optionally, the beam information, spatial correlation information, spatial transmission filter (spatial domain transmission filter) information, spatial filter (spatial filter) information, TCI state information, QCL parameters, beam association relation, and the like mentioned in the present application are in approximately the same meaning.

The downlink beam information may be generally represented by TCI state information and QCL information. Upstream beam information may generally be represented using spatial relationship information.

3. With respect to beam measurements 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 network side equipment adopts 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 side device configures a reference signal resource set (RS resource set) comprising at least one reference signal resource, such as SSB resource or CSI-RS resource. The UE measures the reference signal received power (Layer 1Reference Signal Received Power,L1-RSRP)/signal to interference plus noise ratio (Signal to Interference plus Noise Ratio, L1-SINR) of Layer 1 of each RS resource, and reports the optimal at least one measurement result to the network side equipment, wherein the report content comprises a Synchronous Signal Block Resource Indication (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 to use for transmitting the channel or signal to the terminal.

When only one L1-RSRP is included in the terminal feedback report, a 7bit quantization method is used, the quantization step is 1dB, and the quantization range is-140 dBm to-44 dBm. When multiple L1-RSRP are included in the feedback report that the terminal is instructed to, or group-based beam reporting (group based beam report) is enabled, the strongest RSRP quantization uses 7bit quantization, the rest of the RSRP quantization uses a 4bit differential quantization method, the quantization step is 2dB.

Optionally, the number of feedback reports is determined by parameters configured to the terminal by the network side device, and the number of RSs and RSRPs that should be included in the feedback report of the terminal is configured by the RRC configuration parameters, where the number configuration has a value of 1, 2, 3 or 4, and a default value of 1, and the number limitation is based on the capability of the terminal, and the terminal will report the maximum number that can be supported first.

4. Beam prediction is performed using AI methods.

One possible approach is shown in fig. 3, 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.

In addition, as shown in fig. 4 below, there is a 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 Identification (ID) information, etc. corresponding to the beam pair selected for input. Thus, the number of inputs to such a model is 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.

There is also a method based on the above improvement, as shown in fig. 5. The output of the AI model is affected primarily by the AI model changing the desired information.

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

beam quality related information;

association information about the beam;

the transmitting end transmits the association information related to the wave beam;

the receiving end receives the association information related to the wave beam;

the association information of the wave beam expected by the receiving end;

a receiving end expects the receiving end to receive the association information related to the wave beam;

a sending end expected by a receiving end sends association information related to wave beams;

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.

When the AI model is applied, there may be a case,

if the AI model is located at the terminal side, the terminal predicts at least one optimal beam based on the AI model, and feeds back the predicted at least one optimal beam, at this time, after receiving the feedback information, the base station configures and transmits the predicted at least one optimal beam according to the feedback information, and the terminal performs measurement after receiving and feeds back the measurement result. Thus, there are two feedback modes, one is predictive feedback, and the feedback is a predicted value. The other is normal measurement feedback, which is based on the measurement feedback mode of the related technology.

In another possible process, if the AI model needs to perform model training, performance monitoring, and feedback of measurement results for prediction, more measurement results are needed to be included in the feedback report. Here, there are also two feedback methods, one is a measurement feedback method based on the related art, that is, a normal measurement feedback. The other is that the feedback report needs to contain more measurement results, i.e. enhanced measurement feedback.

Alternatively, the feedback report may be referred to as a measurement report.

The measurement feedback processing method provided by the embodiment of the application is described in detail below by some embodiments and application scenarios thereof with reference to the accompanying drawings.

Step 601, a terminal performs measurement on a reference signal; wherein the measurements in embodiments of the present application may include, but are not limited to, beam measurements.

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

Wherein the measurement report satisfies at least one of:

In the embodiment of the present application, the measurement report type of the measurement report may include any one of the following: normal measurement reports, predictive measurement reports, and enhanced measurement reports.

The normal measurement report may be understood as a conventional measurement report, for example, reporting information and/or channel quality information corresponding to one or more reference signals having measurement results ordered from high to low based on the last measurement result.

The above-mentioned predicted measurement report may be understood as a measurement report that is fed back after the beam prediction based on the measurement result, where the beam corresponding to the beam prediction may include a beam other than the beam corresponding to the beam configured to perform the measurement, for example, the network side device is configured with the beam configured to perform the measurement being the beam 1 to the beam 10 (i.e. the measurement beam associated with the measurement report), the beam predicted after the measurement is the beam 1 to the beam 256, and the beam fed back last is the 20 th 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 with which the measurement report is associated. Alternatively, the beam prediction may be understood as performing beam prediction using an AI model, for example, the measurement result is input into the AI model, so as to obtain a result of beam prediction.

The enhanced measurement report described above may be understood as an enhancement of the measurement report. Wherein enhancing the measurement report corresponds 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 result of a plurality of periods may be included, where the feedback information includes at least one of information corresponding to the reference signal and channel quality information.

The number of target information may be understood as the number of information corresponding to the reference signal, or the number of information corresponding to the reference signal and the channel quality information together, where the information corresponding to the reference signal and the channel quality information are associated with each other. For example, the network side device configures the terminal with the number of target information included in the measurement report to be 4, and actually the feedback measurement report includes 4 RSRPs and indexes of reference signals corresponding to the 4 RSRPs, where the second number is 4, which may be expressed as the number of RSRPs, or may be expressed as the number of indexes of the reference signals corresponding to the RSRPs together (or jointly).

Optionally, the information corresponding to the reference signal may be referred to as beam information, and in some embodiments, the information corresponding to the reference signal includes at least one of the following: information for determining an spatial filter identification of a transmission direction, information for determining an spatial filter identification of a reception direction, information for determining an spatial filter identification, angle-related information of a transmission direction, angle-related information of a reception direction, angle-related information, transmission-direction spatial filter expectation-related information and reception-direction spatial filter expectation-related information.

In other words, the beam information includes at least one of: the beam identification related information of the transmission beam, the beam identification related information of the reception beam, the beam identification related information of the beam pair, the angle related information of the transmission beam, the angle related information of the reception beam, the angle related information, the beam gain related information, the beam width related information, the transmission beam desire related information, and the reception beam desire related information.

Wherein the beam identification related information is related information for characterizing the identity 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) ID corresponding to the beam, random ID of unique identification, encoded value and angle-related information after additional AI network processing, etc. For example, in some embodiments, the beam identification related information may include a channel state information reference signal resource indication (Channel State Information Reference Signal Resource Indicator, CRI), a synchronization signal block resource indication (Synchronization Signal and PBCH block Resource Indicator, SSBRI), and so on.

Optionally, the angle-related information is used to characterize angle-related information corresponding to the beam, where the angle-related information is specifically used to characterize angle or identity-related information, such as angle, radian, index code value, ID value, code value after additional AI network processing, and the like.

Optionally, in some embodiments, the channel quality information includes at least one of: layer 1 signal to interference plus noise ratio, layer 1 reference signal received power, layer 1 reference signal received quality, 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).

Alternatively, the measurement report association target information and the first quantity indication information may be understood as: the measurement report contains target information and first quantity indication information, or the measurement report has an association relationship with the target information and the first quantity indication information. Because the measurement report is associated with the first quantity indication information, the terminal does not need to feed back according to the quantity of the target information configured by the network side equipment, so that the quantity of the reported target information can be reduced, and meanwhile, the network side equipment can accurately understand the measurement report. Therefore, in the embodiment of the application, the overhead of the measurement report can be reduced.

Optionally, the information corresponding to the measurement report associated target reference signal may be understood as: the measurement report contains information corresponding to the target reference signal, or the measurement report has an association relationship with the information corresponding to the target reference signal. Since the number of pieces of information corresponding to the target reference signal is smaller than the number of pieces of beam information associated with the measurement report configuration in the case where the information corresponding to the target reference signal includes the information corresponding to the reference signals of N1 reception directions, the information corresponding to the reference signals of N2 reception directions, or the information corresponding to the N3 reference signals, at least one of N1 and N2 is smaller than the number of pieces of information corresponding to the reference signals associated with the measurement report configuration in the case where the information corresponding to the target reference signal includes the information corresponding to the reference signals of N1 reception directions and the information corresponding to the reference signals of N2 reception directions. Therefore, the overhead of measurement reporting can be reduced.

Optionally, in some embodiments, the first quantity indication information is used to indicate the first quantity or a third quantity, the third quantity is used to determine the first quantity in combination with a second quantity, the second quantity is determined based on a second quantity indication information associated with the measurement report configuration, and the first quantity is less than or equal to the second quantity.

In this embodiment of the present application, the association of the measurement report configuration with the second number of indication information may be understood as: the measurement report configuration comprises second quantity indication information, or an association relation exists between the measurement report configuration and the second quantity indication information.

Alternatively, in the case where the first quantity indication information is used to indicate the third quantity, it may be understood that the first quantity is determined based on the first quantity indication information and the second quantity indication information together.
