CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to a Chinese patent application filed with the China Patent Office on November 10, 2022, with application number 202211407837.9 and title “Beam Prediction Method, Device, Terminal, Network Side Equipment and Storage Medium”, the entire contents of which are incorporated by reference in this application.

Technical Field

The present application belongs to the field of communication technology, and specifically relates to a beam prediction method, apparatus, terminal, network-side equipment and storage medium.

Background technique

At present, artificial intelligence (AI) technology has been widely used in the field of communications. For example, in beam prediction, the beam quality information of some beam pairs is obtained through beam measurement, and the beam quality information of some beam pairs is input into the AI model, so that the beam quality information of all beam pairs at a certain moment in the future can be predicted, and then the optimal beam can be selected based on the beam quality information of all beam pairs to send channels or signals.

However, the AI model only relies on beam quality information for beam prediction, and the information used for reasoning is relatively small, making it difficult to obtain better prediction performance. At the same time, the AI model uses beam quality information at multiple historical moments for beam prediction. If the beam information corresponding to these multiple historical moments is consistent, the prediction performance will decline. If the beam information changes, the prediction performance will be aggravated because the AI model does not obtain the relevant information after the change during reasoning.

To facilitate understanding, the relevant technologies and concepts involved in the embodiments of the present application are first introduced.

1) About AI

AI technology is widely used in various fields such as communications, medical treatment, and education. There are many ways to implement AI networks, such as neural networks, decision trees, support vector machines, Bayesian classifiers, etc. The embodiment of the present application takes the AI network as a neural network as an example for illustration, but does not limit the specific type of AI network.

A schematic diagram of a neural network is shown in Figure 2, including an input layer, a hidden layer, and an output layer. The neural network is composed of neurons, and a schematic diagram of a neuron is shown in Figure 3:
z＝ _a1w1 +…+ _akwk ₊ …+ _aKwK ₊ _b ；

Among them, a ₁ , a ₂ , …, a _k , …, a _K are inputs, w is the weight (multiplicative coefficient), b is the bias (additive coefficient), and σ(.) is the activation function. Common activation functions include Sigmoid, tanh, ReLU (Rectified Linear Unit, linear rectification function, rectified linear unit), etc.

The parameters of the neural network are optimized through an optimization algorithm. An optimization algorithm is a type of algorithm that can minimize or maximize an objective function (or 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, a neural network model f(.) can be constructed. After obtaining the neural network model, the predicted output f(x) can be obtained based on the input x, and the difference f(x)-Y between the predicted value and the true value can be calculated. This is the loss function. The purpose is to find suitable W and b to minimize the value of the above loss function. The smaller the loss value, the closer the prediction result of the neural network model is to the actual situation.

At present, the common optimization algorithms are basically based on the error back propagation (BP) algorithm. The basic idea of the BP algorithm is that the learning process consists of two processes: the forward propagation of the signal and the back propagation of the error. During the forward propagation, the input sample is transmitted from the input layer, processed by each hidden layer layer by 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 back propagation stage. Error back propagation is to propagate the output error layer by layer through the hidden layer to the input layer in some form, and distribute the error to all units in each layer, so as to obtain the error signal of each layer unit, and this error signal is used as the basis for correcting the weights of each unit. This process of adjusting the weights of each layer of the signal forward propagation and error back propagation is repeated. The process of continuous adjustment of weights is the learning and training process of the network. This process continues until the error of the network output is reduced to an acceptable level, or until the pre-set number of learning times is reached.

Common optimization algorithms include Gradient Descent, Stochastic Gradient Descent (SGD), mini-batch gradient descent, Momentum, Nesterov (the name of the inventor, specifically stochastic gradient descent with momentum), Adaptive Gradient Descent (Adagrad), Adaptive learning rate adjustment (Adadelta), root mean square error prop (RMSprop), Adaptive Moment Estimation (Adam), etc.

When these optimization algorithms backpropagate errors, they all calculate the derivative/partial derivative of the current neuron based on the error/loss obtained from the loss function, add the influence of the learning rate, the previous gradient/derivative/partial derivative, etc., get the gradient, and pass the gradient to the previous layer.

2) Beam measurement and beam reporting

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

Currently, polling is usually used to train the simulated beamforming vector, that is, the array elements of each polarization direction of each antenna panel send training signals (i.e. candidate beamforming vectors) in turn at the agreed time in a time-division multiplexing manner. After measurement, the terminal feeds back a beam report for the network side equipment to use the training signal to implement simulated beam transmission when transmitting services next time. The content of the beam report usually includes the optimal number of transmit beam identifiers and the measured receive power of each transmit beam.

When performing beam measurement, the network side device will configure a reference signal (RS) resource set (RS resource set), which includes at least one reference signal resource (RS resource), such as a synchronization signal block (Synchronization Signal Block, SSB) resources (SSB resource) or Channel State Information-Reference Signal (CSI-RS) resources (CSI-RS resource). The terminal measures the reference signal receiving power (Reference Signal Receiving Power, RSRP) (L1-RSRP) and the signal to interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR) (L1-SINR) of layer 1 of each reference signal resource, and reports at least one optimal measurement result to the network side device, and the report content includes the synchronization signal block resource indication (Synchronization Signal Block Resource Indicator, SSBRI) or the channel state information reference signal resource indication (Channel State Information-Reference Signal Resource Indicator, CRI), and L1-RSRP/L1-SINR. The report content reflects at least one optimal beam and its quality, so that the network side device can determine the beam used to send the channel or signal to the terminal.

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

The number of feedback reports is determined by the parameters configured by the network side device to the terminal. The number of RS and RSRP that should be included in the terminal's feedback report is configured through the Radio Resource Control (RRC) configuration parameters. The value of the number configuration is 1, 2, 3, 4, and the default value is 1. In addition, the number is limited based on the terminal's capabilities, and the terminal will first report the maximum number it can support.

3) About using AI models for beam prediction

A possible way to use the AI model for beam prediction is shown in Figure 4. The RSRP of some beam pairs is used as the input of the AI model, and the output of the AI model is the RSRP result of all beam pairs. The beam pair consists of a transmit beam and a receive beam. The number of inputs to the AI model is equal to the number of selected partial beam pairs, and the number of outputs of the AI model is equal to the number of all beam pairs.

Another possible way to use the AI model for beam prediction is shown in FIG5 , where association information is added to the input side of the AI model. The association information is the relevant information corresponding to the input beam pair, such as angle-related information, beam identification (ID) information, etc. The number of inputs to the AI model is still equal to the number of selected partial beam pairs, and the number of outputs of the AI model is still equal to the number of all beam pairs. Adding association information helps to enhance beam prediction performance.

Another possible way to use the AI model for beam prediction is shown in FIG6 , which mainly affects the output of the AI model by changing the expected information through the AI model, such as changing the expected receiving angle information, or changing the expected sending angle information, or changing the expected prediction time related information, and then cyclically using the AI model for prediction. The input type of the AI model may include at least one of the following:

Information related to beam quality;

Beam information;

End A sends beam information;

End B receives beam information;

The beam information expected by the B end;

The B-side receiving beam information expected by the B-side;

The beam information that the B end expects the A end to send;

Time-dependent information related to beam quality;

Information about the expected forecast time.

4) About beam quality information and beam information

Beam quality information includes but is not limited to at least one of the following types: L1-SINR, L1-RSRP, reference signal receiving quality (Reference Signal Receiving Quality, RSRQ) of layer 1 (L1-RSRQ), L3-SINR, L3-RSRP, L3-RSRQ, etc.

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

Among them, the beam ID information is related information used for beam identification, including but not limited to at least one of the following: transmit beam ID, receive beam ID, beam ID, reference signal set ID corresponding to the beam, reference signal resource ID corresponding to the beam, uniquely identified random ID, additional AI network processed coded value, beam angle information, resource index information, CRI, SSBRI, etc.;

The beam angle information is the angle information corresponding to the beam, including but not limited to at least one of the following: angle related information, transmission angle related information, and reception angle related information;

Angle-related information is related information used to characterize angles or identities, such as angles, radians, index encoding values, ID values, encoding values after additional AI network processing, etc.

5) Beam report configuration and beam resource configuration

The corresponding association relationships are: report configuration is associated with resource configuration, resource configuration is associated with beam resource set configuration, and beam resource set configuration is associated with beam resource configuration.

It can correspond to the following relationship: CSI report configuration (CSI-ReportConfig) is associated with CSI resource configuration (CSI-ResourceConfig), CSI resource configuration (CSI-ResourceConfig) is associated with resource set (Resource Set) and time domain behavior.

If a CSI-RS resource set is used, the corresponding one is a non-zero power (NZP) CSI-RS resource set (NZP-CSI-RS-ResourceSet), in which the NZP-CSI-RS-Resoure is associated, and the time domain behavior is used to indicate the time domain periodicity attribute associated with the CSI-RS resource set;

If the SSB resource set is used, the corresponding one is the CSI-SSB resource set (CSI-SSB-ResourceSet), in which the SSB index (index) is associated, and the time domain behavior is invalid at this time.

In addition, a CSI-ReportConfig (beam report configuration) contains up to three CSI-ResoureConfig (beam resource configuration), the specific relationship is as follows:

Aperiodic CSI-ReportConifg can be associated with periodic and semi-persistent CSI-ResourceConfig, and up to 3 beam resource configurations can be configured;

Among them, when 1 CSI-ResourceConfig is configured, it is used for channel measurement (Channel Measurement, CM), including L1-RSRP measurement;

When two CSI-ResourceConfigs are configured, the first beam resource configuration is used for channel measurement, and the second beam resource configuration is used for interference measurement (Interference Measurement, IM), including interference measurement of zero-power (Zero-Power, ZP) resources;

When three CSI-ResourceConfigs are configured, the first beam resource configuration is used for channel measurement, the second beam resource configuration is used for interference measurement, including interference measurement of ZP resources, and the third beam resource configuration is used for interference measurement, including interference measurement of NZP resources.

Semi-persistent CSI-ReportConifg can be associated with periodic and semi-persistent CSI-ResourceConfig, and can be configured with up to 2 beam resource configurations;

Among them, when 1 CSI-ResourceConfig is configured, it is used for channel measurement, including L1-RSRP measurement;

When two CSI-ResourceConfigs are configured, the first beam resource configuration is used for channel measurement, and the second beam resource configuration is used for interference measurement, including interference measurement of ZP resources.

Periodic CSI-ReportConifg can be associated with periodic and semi-persistent CSI-ResourceConfig, and up to 2 beam resource configurations can be configured;

When two CSI-ResourceConfigs are configured, the first beam resource configuration is used for channel measurement, and the second beam resource configuration is used for interference measurement, including interference measurement of ZP resources;

And the time domain behaviors of one or more CSI-ResourceConfigs associated with CSI-ReportConfig are consistent.

For periodic and semi-persistent CSI-ResourceConfig, only one resource set is supported. However, if groupBasedbeamReporting is supported in the beam report, two resource sets can be configured.

For non-periodic CSI-ResourceConfig, there is no limit of 1 resource set, and a maximum of 16 resource sets can be configured.

A CSI-RS resource set supports up to 64 NZP CSI-RS resources. When reportQuantity is none, or channel state information reference signal resource indication-resource indication-channel quality indication (Channel Quality Indicator, CQI) (cri-RI-CQI), or channel state information reference signal resource indication-reference signal received power (cri-RSRP), or synchronization signal block-index-reference signal received power (ssb-Index-RSRP), all CSI-RS resource sets support a total of up to 128 resources.

Furthermore, if the repetition information associated with the CSI-RS resource set is configured to be on, the terminal will assume that all CSI-RS resources in the CSI-RS resource set use the same transmit beam information when sending. If it is configured to be off, the terminal will not assume that these CSI-RS resources use the same transmit beam information when sending. In other words, the repetition parameter in the CSI-RS resource set can control the beam information attributes of all resources associated with the resource set.

The above introduces the relevant technologies and concepts involved in the embodiments of the present application. The following describes in detail the beam prediction method provided in the embodiments of the present application through some embodiments and their application scenarios in combination with the accompanying drawings.

Referring to FIG. 7 , which is a flowchart of an implementation of a beam prediction method provided in an embodiment of the present application, the method may include the following steps:

S710: The terminal receives first configuration information from a network side device, where the first configuration information is associated with at least one beam information Subset, the beam scanning resource associated with the first configuration information is associated with a beam information subset in each sending cycle.

First of all, it should be noted that "association" in the embodiments of the present application can mean "inclusion" or "the existence of an association relationship". For example, A is associated with B, which can mean that A includes B, or that there is an association relationship between A and B, and B can be known through A.

In an embodiment of the present application, a network side device may configure first configuration information, and the first configuration information may be associated with at least one beam information subset, and each beam information subset may be associated with at least one beam information. A beam information refers to relevant information of a beam, and may include beam ID information, beam angle information, beam gain information, beam width information, etc.

The first configuration information may also be associated with beam scanning resources, which may also be referred to as beam resources, such as CSI-RS resources, SSB resources, etc. The network side device may configure the beam scanning resources associated with the first configuration information in each transmission period of the first window associated with the first configuration information, and the beam scanning resources may be associated with a subset of beam information in each transmission period. Each first window may include multiple transmission periods of the beam scanning resources associated with the first configuration information.

S720: The terminal performs beam measurement and beam prediction based on the first configuration information.

After receiving the first configuration information, the terminal can obtain at least one beam information subset associated with the first configuration information, and at the same time can obtain the beam information subset associated with the beam scanning resource associated with the first configuration information in each sending cycle. The terminal can perform beam measurement based on this information.

Optionally, the terminal may measure the beam scanning resources associated with the first configuration information in a first window to obtain beam quality information corresponding to the first window.

Optionally, there may be multiple sending cycles in a first window, and the terminal measures the beam scanning resources in each sending cycle in a first window to obtain beam quality information corresponding to the multiple sending cycles.

The first window may be determined by at least one of protocol agreement, network side device configuration, and terminal reporting.

The terminal performs beam measurement based on the first configuration information and can obtain corresponding beam quality information. When the beam information subset associated with the beam scanning resource in each transmission cycle is associated with part of the beam information, the beam quality information is the beam quality information of the partial beam pair; when the beam information subset associated with the beam scanning resource in each transmission cycle is associated with all the beam information, the beam quality information is the beam quality information of all the beam pairs.

Furthermore, the terminal can input the obtained beam quality information and the beam information associated with the beam scanning resource associated with the first configuration information in each sending cycle into the AI model. Through the reasoning of the AI model, it can predict the beam quality information and/or beam information at a certain moment or certain moments in the future, or predict the beam quality information and/or beam information of more beams at the current moment.

The embodiment of the present application can add the beam information associated with the beam scanning resource associated with the first configuration information in each sending cycle to the input information of the AI model during beam prediction, so that the information used for AI model reasoning is richer, which helps to improve the accuracy of beam prediction, and further helps to accurately determine the beam used to send the channel or signal.

By using the method provided in the embodiment of the present application, the first configuration information received by the terminal is associated with at least one beam information subset, and the beam scanning resource associated with the first configuration information is associated with a beam information subset in each sending cycle, beam measurement and beam prediction are performed based on the first configuration information, and the beam scanning resource associated with the first configuration information is associated with a beam information subset in each sending cycle. The beam information associated with each transmission cycle can enrich the input information of beam prediction, so that the AI model can use more information for beam prediction during reasoning, which can improve the beam prediction performance, which is beneficial to improving the accuracy of beam prediction, and further helps to accurately determine the beam used to send the channel or signal.

In one embodiment of the present application, the total number of beam information in all beam information subsets associated with the first configuration information is greater than or equal to the number of beam scanning resources associated with the first configuration information.

In an embodiment of the present application, the first configuration information is associated with at least one beam information subset, and the total number of beam information in all beam information subsets associated with the first configuration information may be greater than or equal to the number of beam scanning resources associated with the first configuration information. Optionally, the number of beam information in each beam information subset is the same as the number of beam scanning resources associated with the first configuration information. This ensures that the terminal obtains the corresponding beam information when measuring the beam scanning resources.

In one embodiment of the present application, the terminal may receive a first signaling, where the first signaling is used to activate the beam scanning resource and indicate a subset of beam information associated with the beam scanning resource when the time domain characteristics of the beam scanning resource associated with the first configuration information are non-periodic.

In an embodiment of the present application, the time domain characteristic of the beam scanning resource associated with the first configuration information may be periodic, semi-continuous, or non-periodic. The attribute of the beam scanning resource associated with the first configuration information may be repetition off.

When the time domain characteristic of the beam scanning resource associated with the first configuration information is non-periodic, the signaling used to activate the beam scanning resource can be configured to indicate the beam information subset associated with the beam scanning resource. That is, when the beam scanning resource is activated, it can be indicated which beam information subset the beam scanning resource is associated with.

In this way, the beam information subset associated with the activated beam scanning resources can be clarified, which helps the terminal obtain relevant beam information for beam prediction.

In one embodiment of the present application, the first configuration information is also associated with the first window, and each first window includes multiple sending periods of the beam scanning resources associated with the first configuration information, wherein the beam scanning resources corresponding to the i-th sending period in different first windows are associated with the same subset of beam information, i = 1, 2,…, M, M is the number of sending periods in the first window.

In an embodiment of the present application, the first configuration information may be associated with a first window, and within each first window, multiple transmission cycles of the beam scanning resource associated with the first configuration information may be included. For example, a first window may include eight transmission cycles, which may be represented in order as: transmission cycles A1, B1, C1, D1, E1, F1, G1, H1.

The beam scanning resources corresponding to the i-th transmission period in different first windows can be associated with the same beam information subset. For example, based on the above example, there is another first window including eight transmission periods, which are expressed in order as: transmission periods A2, B2, C2, D2, E2, F2, G2, and H2. Among them, A1 and A2 are the first transmission period of different first windows, B1 and B2 are the second transmission period of different first windows, ..., H1 and H2 are the eighth transmission period of different first windows. The beam scanning resources sent in A1 and A2 are associated with the same beam information subset, the beam scanning resources sent in B1 and B2 are associated with the same beam information subset, ..., the beam scanning resources sent in H1 and H2 are associated with the same beam information subset.

The beam scanning resources corresponding to the i-th transmission period in different first windows are associated with the same beam information subset. In this way, corresponding configuration only needs to be performed on one first window, and there is no need to configure each first window, which can improve configuration efficiency.

In one embodiment of the present application, beam scanning resources corresponding to different sending periods within the same first window are associated with different beam information subsets.

For example, the eight sending cycles within a first window are represented in sequence as: sending cycles A1, B1, C1, D1, E1, F1, G1, H1, among which A1 is associated with beam information subset S0, B1 is associated with beam information subset S1,..., H1 is associated with beam information subset S7.

The beam scanning resources sent in different sending periods within the same first window are associated with different beam information subsets, so that in each sending period of a first window, different beams can be used to send beam scanning resources. In this way, when the terminal performs beam measurement, it can measure the beam scanning resources sent on different beams at different measurement times to obtain beam quality information of different beams, expand the beam measurement range, and improve the beam measurement performance. In addition, as the beam measurement range becomes wider, the accuracy of beam prediction will also be higher.

In one embodiment of the present application, at least one of the beam information associated with different beam information subsets is different; and/or, the identifiers of different beam information subsets are different.

In an embodiment of the present application, the first configuration information is associated with at least one beam information subset, each beam information subset can be associated with at least one beam information, and beam scanning resources corresponding to different transmission periods in the same first window are associated with different beam information subsets, and at least one beam information associated with different beam information subsets is different. In this way, when the beam scanning resource associated with the first configuration information is associated with a beam information subset in each transmission period in a first window, the beam information associated with the beam scanning resource in different transmission periods can be different, which helps to expand the beam measurement range and improve the beam measurement performance.

Optionally, the beam information associated with different beam information subsets may be different. For example, the beam information associated with beam information subset S0 includes beam1-8, the beam information associated with beam information subset S1 includes beam9-16, ..., and the beam information associated with beam information subset S7 includes beam57-64.

Assume that the beam scanning resource associated with the first configuration information is associated with beam information subset S0 in sending period A1, associated with beam information subset S1 in sending period B1, ..., and associated with beam information subset S7 in sending period H1. Because the beam information associated with beam information subsets S0, S1, ..., S7 are all different, within a first window, the terminal can measure the beam corresponding to beam information beam1-64, increase the beam measurement range, improve the beam measurement performance, and thus help improve the beam prediction accuracy.

It is understandable that when performing beam prediction, if the beams corresponding to the beam quality information measured at multiple historical moments are the same, for example, the beam quality information corresponding to beam information beam1-8 is measured at moment 1, the beam quality information corresponding to beam information beam1-8 is measured at moment 2, and the beam quality information corresponding to beam1-8 is measured at moment 3, then beam prediction based on such beam quality information will make it difficult to accurately predict the beam quality information and/or beam information corresponding to all beams, resulting in reduced prediction performance. In the embodiment of the present application, beam scanning resources sent in different sending periods within the same first window are associated with different beam information subsets, and at least one of the beam information associated with different beam information subsets is different, so that The beam quality information measured at multiple moments corresponds to different beams, which expands the beam measurement range, thereby helping to improve the beam prediction performance and the beam prediction accuracy.

Optionally, the identifiers of different beam information subsets may be different, that is, the beam information subsets are distinguished by an identifier (ID).

In one embodiment of the present application, the first window may be associated with beam reporting configuration information or beam scanning resource configuration information associated with the first configuration information.

In an embodiment of the present application, the first configuration information may be associated with beam report configuration information and/or beam scanning resource configuration information. The first configuration information is associated with a first window, and the first window may be associated with beam report configuration information or beam scanning resource configuration information. That is, the first window may be associated with the beam report configuration information or with the beam scanning resource configuration information. Optionally, if the first window is associated with the beam report configuration information, the first window may be associated with the beam scanning resource associated with the beam report configuration information.

Establishing associations between multiple types of information allows one type of information to be used to obtain another type of information, which helps to better utilize various types of information during beam measurement and/or beam prediction.

In one embodiment of the present application, the number N1 of the beam information subsets associated with the first configuration information is the same as the number M of the transmission cycles in the first window associated with the first configuration information, and N1 and M are positive integers;

Alternatively, the number N2 of beam information subsets activated in the first window among the beam information subsets associated with the first configuration information is the same as M, and N2 is a positive integer.

In an embodiment of the present application, the beam information subset may be determined by pre-configuration.

For example, if the number M of transmission cycles in the first window associated with the first configuration information is 8, the number N1 of pre-configured beam information subsets may be 8, that is, 8 beam information subsets are pre-configured. In this way, each transmission cycle of the beam scanning resource in the first window can be associated with a beam information subset.

For another example, if the number M of sending cycles in the first window associated with the first configuration information is 8, then among the pre-configured multiple beam information subsets, the number N2 of beam information subsets activated in the first window can be 8, that is, 8 beam information subsets among the pre-configured multiple beam information subsets are activated in the first window, which further ensures that each sending cycle in the first window can be associated with an activated beam information subset.

In one embodiment of the present application, the beam information subset associated with each sending period of the beam scanning resource associated with the first configuration information within a first window is determined by at least one of the following methods:

Pre-configure the first mode;

The signaling indicates the first mode;

Preset rules first method.

In an embodiment of the present application, the beam scanning resource associated with the first configuration information can be associated with a beam information subset in each sending cycle within a first window. The specific association can be determined by a variety of methods, such as a pre-configured first method, a signaling indication first method, a preset rule first method, etc. These methods can be used alone or in combination.

Optionally, pre-configuring the first manner may include: configuring the beam scanning resource associated with the first configuration information in a Each transmission period in the first window is pre-associated with a subset of beam information.

At least one beam information subset is pre-configured, and the beam scanning resource associated with the first configuration information can be associated with a beam information subset for each transmission period within a first window. The beam information subsets associated with different transmission periods may be the same or different. Alternatively, the beam information subsets associated with some transmission periods within a first window are the same, and the beam information subsets associated with some transmission periods are different. For example, the beam information subsets associated with transmission periods A1 and C1 are the same, both are S0, and the beam information subsets associated with transmission periods B1 and D1 are the same, both are S1, but the beam information subsets associated with transmission periods A1 and C1 are different from the beam information subsets associated with transmission periods B1 and D1.

Optionally, the first signaling indication method may include: configuring or indicating a beam information subset for the first sending period within a first window for the beam scanning resource associated with the first configuration information, the first sending period being any sending period within the first window; and associating a beam information subset for each sending period other than the first sending period within the first window in accordance with a protocol agreement or a preset first rule.

At least one beam information subset is pre-configured, and a beam information subset can be configured or indicated for a first transmission cycle in a first window for a beam scanning resource associated with the first configuration information, and the first transmission cycle can be any transmission cycle in the first window, such as the first transmission cycle, or a middle transmission cycle, or the last transmission cycle. Then, a beam information subset is associated with each transmission cycle other than the first transmission cycle in the first window according to the protocol agreement or the preset first rule.

The preset first rule may be associated with the first association order, that is, a beam information subset is associated with each other sending period in the first window according to the set first association order.

For example, the number of sending cycles in a first window is 8, and the signaling indicates that the second beam information subset is associated in the first sending cycle. According to the association relationship, the subsequent association order is to associate the third beam information subset in the second sending cycle,..., to associate the eighth beam information subset in the seventh sending cycle, and to associate the first beam information subset in the eighth sending cycle.

Optionally, the first method of preset rules may include: associating a beam information subset with each sending period within a first window for the beam scanning resource associated with the first configuration information according to a preset second rule.

The second rule may be associated with the first association order. For example, the number of transmission cycles in a first window is 8, the first beam information subset is associated in the first transmission cycle, the second beam information subset is associated in the second transmission cycle, ..., the eighth beam information subset is associated in the eighth transmission cycle. Alternatively, the eighth beam information subset is associated in the first transmission cycle, the seventh beam information subset is associated in the second transmission cycle, ..., the first beam information subset is associated in the eighth transmission cycle.

Optionally, the first association order based on the first rule and/or the second rule may be a beam information subset identification order, or a beam information subset index order, or a beam information subset configuration order, or a beam information subset time order. The first association order based on the first rule and the second rule may be the same or different.

In one embodiment of the present application, the beam information subset associated with the first configuration information is implicitly determined by the beam information. For example, a beam information subset may be implicitly determined by indicating one or more beam information.

Optionally, the beam information subset associated with each sending period of the beam scanning resource associated with the first configuration information within a first window may be determined in at least one of the following ways:

Pre-configure the second method;

The signaling indicates the second mode;

Preset rules second method.

In an embodiment of the present application, the beam scanning resource associated with the first configuration information can be associated with a beam information subset in each sending cycle within a first window. The specific association can be determined by a variety of methods, such as a pre-configured second method, a signaling indication second method, a preset rule second method, etc. These methods can be used alone or in combination.

Optionally, pre-configuring the second method may include: pre-associating at least one beam information for each sending period within a first window for the beam scanning resource associated with the first configuration information, and the associated at least one beam information implicitly determines a beam information subset.

The beam scanning resource associated with the first configuration information can be associated with at least one beam information for each transmission period within a first window, such as being associated with one beam information, or being associated with a set number of beam information. The beam information associated with different transmission periods can be the same or different. Alternatively, the beam information associated with some transmission periods within a first window is the same, and the beam information associated with some transmission periods is different. For example, the beam information associated with transmission periods A1 and C1 is the same, both are beam1-8, and the beam information associated with transmission periods B1 and D1 is the same, both are beam9-16, but the beam information associated with transmission periods A1 and C1 is different from the beam information associated with transmission periods B1 and D1. The beam information beam1-8 implicitly determines the beam information subset S0, and the beam information beam9-16 implicitly determines the beam information subset S1.

The beam information can be configured or indicated for the first sending cycle within a first window for the beam scanning resource associated with the first configuration information. The first sending cycle can be any sending cycle within the first window, such as the first sending cycle, or an intermediate sending cycle, or the last sending cycle. Then, the beam information is associated with each sending cycle except the first sending cycle in the first window according to the protocol agreement or a preset third rule.

The preset third rule may be associated with the second association order, that is, the beam information is associated for each other sending period in the first window according to the set second association order.

For example, the number of sending cycles in a first window is 8, the total number of beam information is 64, the number of beam information in a beam information subset is 8, and the signaling indicates that the beam scanning resource associated with the first configuration information is associated with beam information beam7 in the first sending cycle, and the beam information associated with the beam information subset implicitly determined by the beam information includes beam7-14. According to this association relationship, the subsequent association order is to associate beam information beam15-22 in the second sending cycle,..., and associate beam information beam63-6 in the eighth sending cycle.

For example, the number of transmission cycles in a first window is 8, and beam information beam1-8 is associated in the first transmission cycle, beam information beam9-16 is associated in the second transmission cycle, ..., and beam information 57-64 is associated in the eighth transmission cycle. Alternatively, beam information 64-57 is associated in the first transmission cycle, beam information 56-49 is associated in the second transmission cycle, ..., and beam information 8-1 is associated in the eighth transmission cycle.

Optionally, the second association order based on the third rule and/or the fourth rule may be a beam information identification order, or a beam information index order, or a beam information configuration order, or a beam information time order.

The signaling indication association means configuring or additionally indicating a beam information subset for the first transmission cycle or a certain transmission cycle among the M transmission cycles in the first window, and optionally, the remaining beam information subsets are associated with the transmission cycle according to a preset rule;

For example, according to the indicated association position, the order of the beam information subsets is associated with the order of the transmission cycles, M=8, the signaling indicates that the second beam information subset is associated in the first transmission cycle, and according to the association position, the subsequent association order is to associate the third beam information subset in the second transmission cycle, ..., until the first beam information subset is associated in the eighth transmission cycle;

The preset rule association means associating M beam information subsets according to the preset rule for M transmission cycles in the first window;

For example, in order of association, M=8, the first beam information subset is associated in the first transmission cycle, the second beam information subset is associated in the second transmission cycle, ..., the eighth beam information subset is associated in the eighth transmission cycle;

For example, M=8, a total of 64 beam information, the number of beam information in the beam information subset is equal to 8, the ID is from 1-64, and the beam information associated in the first transmission cycle is 7. Then the beam information associated in the first transmission cycle includes 7 to 14, the beam information associated in the second transmission cycle includes 15 to 22, and so on. Beam information includes 63 to 6;

The preset rule association is to implicitly associate beam information with the beam scanning resources corresponding to each sending cycle in the first window according to the preset rule;

When using historical cycles or historical measurement resources for beam prediction, multiple historical cycles or multiple historical measurement values are generally used to predict future beams through multiple historical values. In the current beam resource configuration in related technologies, the beam scanning resources associated with a beam feedback report cannot be changed unless the resources are reconfigured, which means that the beam scanning resources are the same in multiple cycles or multiple measurement moments. In other words, during time domain prediction, more RSRP information on the measurement cycle will be collected to predict future beam information. If the beams of the beam scanning resources measured at multiple historical moments are the same, the prediction performance will be reduced. Through the technical solution provided in the embodiments of the present application, the beam scanning resources in each sending cycle or measurement cycle can be different, which can increase the range of beam measurement and help improve the accuracy of beam prediction.
