For convenience of understanding, related technologies and concepts related to the embodiments of the present application will be described first.

1) Regarding AI

AI technology is widely used in various fields such as communication, medical treatment, education, etc. There are a number of implementations of AI networks, such as neural networks, decision trees, support vector machines, bayesian classifiers, etc. The embodiment of the application is described by taking an AI network as a neural network as an example, but the specific type of the AI network is not limited.

A schematic diagram of a neural network is shown in fig. 2, comprising an input layer, a hidden layer, and an output layer. The neural network is composed of neurons, and a schematic diagram of the neurons is shown in fig. 3:

z＝a₁w₁+…+a_kw_k+…+a_Kw_K+b；

Where a ₁、a₂、…、a_k、…、a_K is the input, w is the weight (multiplicative coefficient), b is the bias (additive coefficient), and σ () is the activation function (activation function). Common activation functions include Sigmoid, tanh, reLU (RECTIFIED LINEAR Unit, linear rectification function, modified linear Unit), etc.

The parameters of the neural network are optimized by an optimization algorithm. An optimization algorithm is a class of algorithms that can minimize or maximize an objective function (or referred to as a loss function). The objective function is often a mathematical combination of model parameters and data. For example, given data X and its corresponding label Y, a neural network model f (), and then after obtaining the neural network model, a predicted output f (X) can be obtained from the input X, and a difference f (X) -Y between the predicted value and the true value, which is a loss function, can be calculated. The aim is to find a suitable W, b to minimize the value of the loss function, and the smaller the loss value is, the closer the predicted result of the neural network model is to the real situation.

The most common optimization algorithms are basically based on an error back propagation (error Back Propagation, BP) algorithm. 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), small-batch gradient descent (mini-batch GRADIENT DESCENT), momentum method (Momentum), nesterov (name of the inventor, specifically random gradient descent with Momentum), adaptive gradient descent (ADAPTIVE GRADIENT DESCENT, adagrad), adaptive learning rate adjustment (Adadelta), root mean square error descent (root mean square prop, RMSprop), adaptive Momentum estimation (Adaptive Moment Estimation, adam), and the like.

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 measurements and Beam 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, 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 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 beam measurement, the network side device configures a reference signal (REFERENCE SIGNAL, RS) resource set (RS resource set) including at least one reference signal resource (RS resource), such as a synchronization signal block (Synchronization Signal Block, SSB) resource (SSB resource) or a channel state Information reference signal (CHANNEL STATE Information-REFERENCE SIGNAL, CSI-RS) resource (CSI-RS resource). The terminal measures reference signal received Power (REFERENCE SIGNAL RECEIVING Power, RSRP) of layer 1 (L1-RSRP), signal-to-interference-plus-noise ratio (Signal to Interference plus Noise Ratio, SINR) (L1-SINR) of each reference signal 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 (Synchronization Signal Block Resource Indicatior, SSBRI) or a channel state Information reference signal resource indication (CHANNEL STATE Information-REFERENCE SIGNAL Resource Indicatior, 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 the terminal feedback report contains a plurality of L1-RSRPs or packet-based beam reports (group based beam report) are enabled, the strongest RSRP is quantized by using a 7-bit quantization method, and the rest RSRPs are quantized by using a 4-bit differential quantization method, wherein the quantization step is 2dB.

The number of feedback reports is determined by parameters configured to the terminal by the network side equipment, the number of RSPs and RSRPs which should be contained in the feedback report of the terminal are configured by the radio resource control (Radio Resource Control, RRC) configuration parameters, the value of the number configuration is 1, 2, 3 and 4, and the default value is 1. In addition, the number is limited based on the terminal capabilities, and the terminal will report the maximum number that can be supported first.

3) Regarding beam prediction using AI model

One possible way of beam prediction using AI models is shown in fig. 4. The RSRP of a partial beam pair is used as input to the AI model, the output of which 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 AI models is equal to the number of selected partial beam pairs and the output number of AI models is equal to the number of all beam pairs.

Another possible way of beam prediction using the AI model is shown in fig. 5, where association information is added to the input side of the AI model, where the association information is related information corresponding to the input beam pair, such as angle related information, beam Identification (ID) information, and so on. The number of inputs of the AI model is also equal to the number of selected partial beam pairs, and the number of outputs of the AI model is also equal to the number of all beam pairs. Adding association information helps to enhance beam prediction performance.

Another possible way of beam prediction using the AI model is shown in fig. 6, where the AI model is mainly used to change the desired information to affect the output of the AI model, e.g. the desired receiving angle information may be changed, or the desired transmitting angle information may be changed, or the desired prediction time related information may be changed, and then the AI model is recycled for prediction. Wherein the input type of the AI model may include at least one of:

Beam quality related information;

Beam information;

The A end transmits beam information;

the B end receives the wave beam information;

The beam information expected by the B end;

the expected B end receives the wave beam information;

The A terminal expected by the B terminal sends beam information;

time-related information related to beam quality;

Expected predicted time related information.

4) Information about beam quality and beam information

The beam quality information includes, but is not limited to, at least one of the following types: L1-SINR, L1-RSRP, reference Signal Received Quality (RSRQ) of layer 1 (REFERENCE SIGNAL RECEIVING Quality) (L1-RSRQ), L3-SINR, L3-RSRP, L3-RSRQ, and the like.

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

Wherein the beam ID information is related information for identification of the beam, including but not limited to at least one of the following: transmitting a beam ID, receiving a 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 information, resource index information, CRI, SSBRI and the like;

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

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

5) Beam reporting configuration and beam resource configuration

The corresponding association relation is as follows: reporting the configuration associated resource configuration, the resource configuration associated beam resource set configuration, the beam resource set configuration associated beam resource configuration.

May correspond to the following relationship: CSI reporting configuration (CSI-ReportConfig) associated CSI Resource configuration (CSI-ResourceConfig), CSI Resource configuration (CSI-ResourceConfig) associated Resource Set (Resource Set) and time behavior.

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

If SSB resource sets are used, corresponding are CSI-SSB resource sets (CSI-SSB-resource) in which SSB indices (indices) are associated, where time domain behavior is invalid.

In addition, one CSI-ReportConfig (beam reporting configuration) contains at most three CSI-ResoureConfig (beam resource configurations), and the specific relationship is as follows:

aperiodic CSI-ReportConifg may be associated with periodic, semi-persistent CSI-ResourceConfig, with a maximum of 3 beam resource configurations configurable;

When 2 CSI-ResourceConfig are configured, a first beam resource is configured for channel measurement, a second beam resource is configured for interference measurement (INTERFERENCE MEASUREMENT, IM), including interference measurement of Zero-Power (ZP) resources;

When 3 CSI-ResourceConfig are configured, the first beam resource is configured for channel measurement, the second beam resource is configured for interference measurement, including interference measurement of ZP resources, and the third beam resource is configured for interference measurement, including interference measurement of NZP resources.

Semi-persistent CSI-ReportConifg may be associated with periodic, semi-persistent CSI-ResourceConfig, with a maximum of 2 beam resource configurations being configurable;

Wherein, when 1 CSI-ResourceConfig is configured, the method is used for channel measurement, including L1-RSRP measurement;

and the time domain behavior of the associated 1 or more CSI-ResourceConfig in CSI-ReportConfig is consistent.

For periodic and semi-persistent CSI-ResourceConfig only 1 Resource set is supported, but if groupBasedbeamReporting is supported in the beam report, 2 Resource sets may be configured;

for aperiodic CSI-ResourceConfig, not limited to 1 set of resources, a maximum of 16 may be configured.

A maximum of 64 NZP CSI-RS resources are supported in one CSI-RS resource set, and when the reporting quality (reporting quality) is none, or channel state information reference signal resource indication-channel quality indication (Channel Quality Indicatior, 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 a maximum of 128 resources.

Furthermore, if the repetition (repetition) information associated with the CSI-RS resource set is configured to be turned on (on), the terminal may assume that all CSI-RS resources in the CSI-RS resource set use the same transmit beam information when transmitting. If configured to turn off (off), the terminal does not assume that these CSI-RS resources use the same transmit beam information when transmitting. That is, the repetition parameter in the CSI-RS resource set may control the beam information attribute of all resources associated with the resource set.

The M beam scanning resource sets associated with the first configuration information can be associated with N beam scanning resources, wherein N is a positive integer and represents the number of beam scanning resources configured by the network side equipment. If N is 64, that is, the M sets of beam scanning resources associated with the first configuration information may be associated with 64 beam scanning resources.

Or each of the M sets of beam scanning resources associated with the first configuration information is associated with N beam scanning resources.

Optionally, the N beam scanning resources are associated with the same first period; and/or, the N beam scanning resources are associated with different slot offsets; the first period is equal to the period of the beam feedback report corresponding to the first configuration information, or equal to the period of the beam scanning resource associated with the first configuration information.

The M sets of beam scanning resources may be associated with one or more subsets of beam scanning resources, each of which may be associated with at least some of the N beam scanning resources. The beam feedback report corresponding to the first configuration information may be associated with a subset of beam scanning resources within each set of beam scanning resources in each transmission period. For any one transmission period, the beam feedback report corresponding to the first configuration information corresponds to the beam scanning resource subset associated with the transmission period and the first beam scanning resource associated with the transmission period.

For example, the first configuration information is associated with a set of beam scanning resources, the set of beam scanning resources is associated with 64 beam scanning resources, the set of beam scanning resources is associated with 8 beam scanning resource subsets, each beam scanning resource subset is associated with 8 beam scanning resources, and the beam feedback report corresponding to the first configuration information is associated with one beam scanning resource subset in each transmission period.

Or the first configuration information is associated with two beam scanning resource sets, each beam scanning resource set is associated with 64 beam scanning resources, each beam scanning resource set is associated with 8 beam scanning resource subsets, each beam scanning resource subset is associated with 8 beam scanning resources, and the beam feedback report corresponding to the first configuration information is associated with two beam scanning resource subsets in each transmission period. For any one transmission period, the two beam scanning resource subsets associated in the transmission period are respectively from the two beam scanning resource sets.

After the terminal receives the first configuration information, the association relations can be defined based on the first configuration information, and the terminal is facilitated to accurately measure the wave beams.

In one embodiment of the present application, the first configuration information is further associated with first windows, each first window including a plurality of transmission periods of the beam feedback report corresponding to the first configuration information, wherein:

The total number of the beam scanning resource subsets is equal to the total number I of the beam feedback reports corresponding to the first configuration information sending periods in the first window.

In the embodiment of the present application, the first configuration information may be associated with a first window, and one first window may include a plurality of transmission periods of the beam feedback report corresponding to the first configuration information. The first window may be determined by at least one of protocol conventions, network side device configuration, and terminal reporting.

The first configuration information is associated with M sets of beam scanning resources, the M sets of beam scanning resources are associated with at least one subset of beam scanning resources, and the total number of the subsets of beam scanning resources may be equal to the total number of transmission periods of the beam feedback report corresponding to the first configuration information in the first window, and may be represented by I, where I is a positive integer. If the total number of transmission periods in the first window is 8, the total number of beam scanning resource subsets is also 8, and the m beam scanning resource sets are associated with 8 beam scanning resource subsets. This enables the possibility of associating different subsets of beam scanning resources with different transmission periods within the first window, which further may help to expand the beam measurement range.

In one embodiment of the present application, the beam feedback reports corresponding to the ith transmission period in different first windows are associated with the same beam scanning resource subset, i=1, 2, … …, I being the total number of transmission periods in the first windows.

In the embodiment of the present application, a plurality of transmission periods of the beam feedback report corresponding to the first configuration information may be included in one first window. For example, there may be eight transmission periods within a first window, which may be expressed in sequence as: transmission periods A1, B1, C1, D1, E1, F1, G1, H1.

The beam feedback reports corresponding to the ith transmission period in different first windows may be associated with the same subset of beam scanning resources. For example, on the basis of the above example, there are eight transmission periods of another first window, expressed in sequence as: transmission periods A2, B2, C2, D2, E2, F2, G2, H2. Wherein A1 and A2 are the first transmission periods of different first windows, B1 and B2 are the second transmission periods of different first windows, … …, and H1 and H2 are the eighth transmission periods of different first windows. The beam feedback reports corresponding to A1 and A2 are associated with the same beam scanning resource subset, the beam feedback reports corresponding to B1 and B2 are associated with the same beam scanning resource subset, … …, and the beam feedback reports corresponding to H1 and H2 are associated with the same beam scanning resource subset.

The beam feedback reports corresponding to the ith transmission period in different first windows are associated with the same beam scanning resource subset, so that corresponding configuration is only needed in one first window, configuration is not needed in each first window, and configuration efficiency can be improved.

In one embodiment of the present application, the beam feedback reports corresponding to different transmission periods within the same first window are associated with different beam scanning resource subsets.

For example, eight transmission periods within a first window are represented in sequence as: the transmission periods A1, B1, C1, D1, E1, F1, G1, H1, wherein the beam scanning resource subset S0 is associated with A1, the beam scanning resource subset S1, … … is associated with B1, and the beam scanning resource subset S7 is associated with H1.

The beam feedback reports corresponding to different sending periods in the same first window are associated with different beam scanning resource subsets, so that beam measurement can be performed based on different beam scanning resources in different sending periods of one first window to obtain beam quality information of different beams, the beam measurement range is enlarged, the beam measurement performance is improved, and in addition, the accuracy of beam prediction is higher due to the fact that the beam measurement range is widened.

In one embodiment of the present application, the periods of beam scanning resources associated with the same subset of beam scanning resources are the same; and/or the periodicity of the beam scanning resources associated with the different beam scanning resource subsets is different. For example, the periods of the beam scanning resources associated with one beam scanning resource subset are 20ms, and the periods of the beam scanning resources associated with the other beam scanning resource subset are 40ms.

In one embodiment of the present application, the subset of beam scanning resources associated with each transmission period of the beam feedback report corresponding to the first configuration information in a first window is determined by at least one of:

Pre-configuring a first mode;

Signaling indicates a first manner;

In the embodiment of the present application, each transmission period of the beam feedback report corresponding to the first configuration information in one first window may be associated with a beam scanning resource subset, and how to specifically associate with the beam scanning resource subset may be determined in multiple manners, for example, a first manner of pre-configuring, a first manner of signaling indicating, a first manner of pre-configuring a rule, etc., which may be used alone or in combination.

Optionally, pre-configuring the first manner may include: the beam scanning resource subset is pre-associated for each transmission period of the beam feedback report corresponding to the first configuration information in a first window.

The first configuration information associates M sets of beam scanning resources, the M sets of beam scanning resources associate N beam scanning resources, or each set of beam scanning resources in the M sets of beam scanning resources associates N beam scanning resources, each subset of beam scanning resources associates at least some of the N beam scanning resources. Each transmission period within a first window for the beam feedback report corresponding to the first configuration information may be associated with a subset of beam scanning resources within each set of beam scanning resources. Wherein the subsets of beam scanning resources associated with different transmission periods may all be the same or all different. Or the beam scanning resource subsets associated with the partial transmission periods within a first window are the same, and the beam scanning resource subsets associated with the partial transmission periods are different. If the beam scanning resource subsets associated with the transmission periods A1 and C1 are the same, S0 is used, and the beam scanning resource subsets associated with the transmission periods B1 and D1 are the same, S1 is used, but the beam scanning resource subsets associated with the transmission periods A1 and C1 are different from the beam scanning resource subsets associated with the transmission periods B1 and D1.

Optionally, the signaling the first manner may include: configuring or indicating a beam scanning resource subset for a first sending period of a beam feedback report corresponding to the first configuration information in a first window, wherein the first sending period is any sending period in the first window;

And scanning a resource subset for each other transmission period except the first transmission period in the first window according to protocol convention or preset first rule association beam.

The beam scanning resource subset may be configured or indicated for a first transmission period of the beam feedback report corresponding to the first configuration information in a first window, where the first transmission period may be any one transmission period, such as the first transmission period, or an intermediate transmission period, or the last transmission period in the first window. And then, for each other transmission period except the first transmission period in the first window, associating the beam scanning resource subset according to the protocol convention or preset first rule.

The preset first rule may be related to a first association order, i.e. associating a subset of beam scanning resources for each other transmission period within the first window according to the set first association order.

For example, the number of transmission periods in a first window is 8, and the signaling indicates that the second subset of beam scanning resources is associated in the first transmission period, and according to the association relationship, the subsequent association sequence is to associate the third subset of beam scanning resources in the second transmission period, … …, associate the eighth subset of beam scanning resources in the seventh transmission period, and associate the first subset of beam scanning resources in the eighth transmission period.

Optionally, the first mode of presetting the rule may include: and according to a preset second rule, the beam feedback report corresponding to the first configuration information is related to the beam scanning resource subset for each sending period in a first window.

For example, the number of transmission periods in a first window is 8, a first subset of beam scanning resources is associated in the first transmission period, a second subset of beam scanning resources is associated in the second transmission period, … …, and an eighth subset of beam scanning resources is associated in the eighth transmission period. Or an eighth subset of beam scanning resources is associated in the first transmission period, a seventh subset of beam scanning resources is associated in the second transmission period, … …, and the first subset of beam scanning resources is associated in the eighth transmission period.

Optionally, the first association order based on the first rule and/or the second rule may include a beam scanning resource subset identification order, or a beam scanning resource subset index order, or a beam scanning resource subset configuration order, or a beam scanning resource subset time order, or a beam scanning resource subset slot offset order. The first association order in which the first rule and the second rule are based may be the same or different.

In one embodiment of the present application, the interval between two adjacent prediction moments corresponding to beam prediction is equal to the second period multiplied by the first value; the second period is equal to the period of the beam feedback report corresponding to the first configuration information, or equal to the period of the beam scanning resource associated with the first configuration information.

In the embodiment of the application, after beam measurement is performed based on the beam scanning resource, beam prediction can be further performed based on the measured beam quality information, the beam quality information of all beam pairs at a certain time or a certain time in the future is predicted, one or more predicted times can be provided, and the interval between two adjacent predicted times corresponding to the beam prediction can be equal to the second period multiplied by the first value. The second period is equal to the period of the beam feedback report corresponding to the first configuration information or the period of the beam scanning resource associated with the first configuration information.

Optionally, the first value is determined according to a number of different time slot offsets associated with beam scanning resources having the same period, e.g. the first value is equal to 1/number of different time slot offsets.

For example, the 16 beam scanning resources are all configured with the same period of 80ms, but every four beam scanning resources are configured with 1 slot offset, such as the 1 st to 4 th beam scanning resources are each configured with 0ms, the 5 th to 8 th beam scanning resources are each configured with 20ms, the 9 th to 12 th beam scanning resources are each configured with 40ms, and the 13 th to 16 th beam scanning resources are each configured with 60ms. Beam prediction is performed by using an AI model, beam quality information of a plurality of future times is predicted, and a time interval between two adjacent predicted times should be 80×1/4=20 ms, instead of 80ms.

In one embodiment of the present application, in the case that the first configuration information and/or the time domain feature associated with the first set of configuration information associated beam scanning resources is periodic or semi-persistent:

M is equal to 1;

Or if packet-based beam feedback reporting (groupBasedBeamReport) is not enabled, then M is equal to 1;

Or if packet-based beam feedback reporting (groupBasedBeamReport) is enabled, M is a second value greater than 1, which may be a defined value, such as 2.

When m=1, the first configuration information associates one set of beam scanning resources, the set of beam scanning resources associates N beam scanning resources, the set of beam scanning resources associates at least one subset of beam scanning resources, each subset of beam scanning resources associates at least some of the N beam scanning resources, and the beam feedback report corresponding to the first configuration information associates one subset of beam scanning resources in each transmission period;

When m=2, the first configuration information associates two beam scanning resource sets, where the two beam scanning resource sets associate N beam scanning resources, or each beam scanning resource set in the two beam scanning resource sets associates N beam scanning resources, where the two beam scanning resource sets associate at least one beam scanning resource subset, where each beam scanning resource subset associates at least part of the N beam scanning resources, and where the beam feedback report corresponding to the first configuration information associates two beam scanning resource subsets in each transmission period, where the two beam scanning resource subsets are each one of the two beam scanning resource subsets.

In one embodiment of the present application, the first configuration information associates p×q sets of beam scanning resources, or associates p×q sets of beam scanning resources activated, where P and Q are positive integers, and the p×q sets of beam scanning resources include P sets of beam scanning resources, each set of beam scanning resources includes Q sets of beam scanning resources, and each set of beam scanning resources is associated with at least some of the beam scanning resources corresponding to the first configuration information; the beam feedback report corresponding to the first configuration information associates one beam scanning resource set in each group of beam scanning resource sets in each transmission period.

In an embodiment of the present application, each of the p×q sets of beam scanning resources may be associated with at least a portion of the beam scanning resources. The method comprises the steps of dividing total beam scanning resources corresponding to first configuration information into a plurality of beam scanning resource sets in advance, and associating a beam feedback report corresponding to the first configuration information with one beam scanning resource set in each group of beam scanning resource sets in each sending period. For any one transmission period, the beam feedback report corresponding to the first configuration information corresponds to the beam scanning resource set associated with the transmission period and the first beam scanning resource associated with the transmission period.

Optionally, the p×q sets of beam scanning resources are associated with the same period; or Q sets of beam scanning resources within each group of beam scanning resource sets are associated with the same period. I.e. the beam scanning resources associated with the P x Q sets of beam scanning resources are all associated with the same period. When the p×q sets of beam scanning resources are P sets of beam scanning resources, each set has Q sets of beam scanning resources, and the beam scanning resources associated with the Q sets of beam scanning resources in each set are all associated with the same period, such as 20ms.

Optionally, the second beam scanning resources associated with the p×q beam scanning resource sets have at least one of the following same characteristics:

Period, slot offset position, frequency domain position, bandwidth size;

The second beam scanning resources are beam scanning resources with the same preset sequence, and the preset sequence comprises a configuration sequence, a time domain sequence, an identification sequence or an index sequence in the beam scanning resource set.

For example, P is 1, the beam scanning resources associated with the first beam scanning resource set of the p×q beam scanning resource sets include resources 1-8, the beam scanning resources associated with the second beam scanning resource set include resources 9-16, wherein resources 1 and 9 are respectively the first beam scanning resources associated with the first beam scanning resource set and the second beam scanning resource set, are considered to be beam scanning resources having the same preset order, have the same characteristics of at least one of the above, and likewise resources 2 and 10 are considered to be beam scanning resources having the same preset order, have the same characteristics of at least one of the above, and … …, resources 8 and 16 are considered to be beam scanning resources having the same preset order, have the same characteristics of at least one of the above.

The preset order may include a configuration order, or a time domain order, or an identification order, or an index order in the set of beam scanning resources.

In one embodiment of the present application, the identities or indexes of the beam scanning resources associated with different beam scanning resource sets in the p×q beam scanning resource sets are all different; or the identity or index of the beam scanning resources associated with different sets of beam scanning resources within each group of beam scanning resources are different.

For example, the p×q sets of beam scanning resources are a group of 8 sets of beam scanning resources, the beam scanning resources associated with the set of beam scanning resources R0 include resources 1-8, the beam scanning resources associated with the set of beam scanning resources R1 include resources 9-16, … …, and the beam scanning resources associated with the set of beam scanning resources R7 include resources 57-64.

Assuming that the beam feedback report corresponding to the first configuration information is associated with the beam scanning resource set R0 in the transmission period A1, and is associated with the beam scanning resource sets R1 and … … in the transmission period B1, and is associated with the beam scanning resource set R7 in the transmission period H1, because the identifiers or indexes of the beam scanning resources associated with the beam scanning resource sets R0, R1, … … and R7 are different, the terminal can implement measurement on the beams corresponding to the beam scanning resources resource1-64 associated with the beam scanning resource set in a first window, so that the beam measurement range is enlarged, the beam measurement performance is improved, and further the beam prediction accuracy is facilitated to be improved.

It can be understood that, in the embodiment of the present application, the beam scanning resource may correspond to beam information, when beam prediction is performed, if beams corresponding to beam quality information at a plurality of historical moments obtained by measurement are the same, for example, beam quality information corresponding to beam information beam1-8 is obtained by measurement at time 1, beam quality information corresponding to beam information beam1-8 is also obtained by measurement at time 2, and beam quality information corresponding to beam1-8 is also obtained by measurement at time 3, then it is difficult to accurately predict beam quality information and/or beam information corresponding to all beams at a future moment or a moment based on such beam quality information, so that prediction performance is degraded. In the embodiment of the application, the beam feedback reports sent in different sending periods in the same first window are associated with different beam scanning resource sets, and the beam scanning resources associated with the different beam scanning resource sets are at least one or all different, so that the beams corresponding to the beam quality information obtained by measuring at a plurality of moments are different, the beam measuring range is enlarged, further the beam predicting performance is improved, and the beam predicting accuracy is improved.

In addition, the identification or index of the beam scanning resources are different, so that the beam scanning resources can be conveniently distinguished, and meanwhile, the beam scanning resources can be conveniently corresponding to the beam information.

P is equal to 1;

Or if packet-based beam feedback reporting (groupBasedBeamReport) is not enabled, P is equal to 1;

or if packet-based beam feedback reporting (groupBasedBeamReport) is enabled, M is a third value greater than 1, which may be a defined value, such as 2.

When p=1, the first configuration information is associated with Q sets of beam scanning resources, or is associated with activated Q sets of beam scanning resources, and the beam feedback report corresponding to the first configuration information is associated with one set of beam scanning resources in each transmission period.

When p=2, the first configuration information associates two sets of Q beam scanning resource sets, or associates two sets of Q beam scanning resource sets that are activated, and the beam feedback report corresponding to the first configuration information associates two beam scanning resource sets in each transmission period, where the two beam scanning resource sets are respectively one beam scanning resource set in the two sets of beam scanning resource sets.

In one embodiment of the present application, the beam scanning resource set associated with each transmission period of the beam feedback report corresponding to the first configuration information in the first window associated with the first configuration information may be determined by at least one of the following manners:

pre-configuring a second mode;

signaling indicates a second manner;

The second mode of rules is preset.

In the embodiment of the present application, each transmission period of the beam feedback report corresponding to the first configuration information in a first window may be associated with a beam scanning resource set, and how to associate may be determined in various manners, for example, a second manner is preconfigured, a second manner is indicated by signaling, a second manner is preset in a rule, etc., which may be used alone or in combination.

Optionally, pre-configuring the second manner may include: and pre-associating a beam scanning resource set for each transmission period of the beam feedback report corresponding to the first configuration information in a first window.

Each transmission period within one first window may be associated with a set of beam scanning resources for a beam feedback report corresponding to the first configuration information. Wherein the sets of beam scanning resources associated with different transmission periods may all be the same or all different. Or the beam scanning resource sets associated with the partial transmission periods in a first window are the same, and the beam scanning resource sets associated with the partial transmission periods are different. If the sets of beam scanning resources associated with the transmission periods A1 and C1 are the same, R1 is used, and the sets of beam scanning resources associated with the transmission periods B1 and D1 are the same, R2 is used, but the sets of beam scanning resources associated with the transmission periods A1 and C1 are different from the sets of beam scanning resources associated with the transmission periods B1 and D1.

Optionally, the signaling the second manner may include: configuring or indicating a beam scanning resource set for a first sending period of a beam feedback report corresponding to the first configuration information in a first window, wherein the first sending period is any sending period in the first window;

and scanning a resource set for each other transmission period except the first transmission period in the first window according to protocol convention or preset third rule association beam.

The beam scanning resource set may be configured or indicated for a first transmission period of the beam feedback report corresponding to the first configuration information in a first window, where the first transmission period may be any one transmission period in the first transmission period, such as the first transmission period, or a certain transmission period in the middle, or the last transmission period, and then the beam scanning resource set is associated with each other transmission period in the first window except for the first transmission period according to a protocol convention or a preset third rule.

The preset third rule may be related to the second association order, i.e. associating the set of beam scanning resources for each other transmission period within the first window according to the set second association order.

For example, the number of transmission periods in a first window is 8, the total number of beam scanning resource sets is 8, the number of beam scanning resources associated with a beam scanning resource set is 8, and signaling indicates that the beam scanning resource set R2 is associated in the first transmission period, and according to the association relationship, the beam scanning resource set R3, … … is associated in the second transmission period, the beam scanning resource set R8 is associated in the seventh transmission period, and the beam scanning resource set R1 is associated in the eighth transmission period.

Optionally, the second mode of presetting the rule may include: and according to a preset fourth rule, reporting a beam scanning resource set associated with each sending period in the first window for the beam feedback corresponding to the first configuration information.

The fourth rule may be related to the second association order. For example, the number of transmission periods in the first window is 8, the beam scanning resource set R1 is associated in the first transmission period, the beam scanning resource sets R2 and … … are associated in the second transmission period, and the beam scanning resource set R8 is associated in the eighth transmission period. Or the beam scanning resource set R8 is associated in the first transmission period, the beam scanning resource sets R7, … … are associated in the second transmission period, and the beam scanning resource set R1 is associated in the eighth transmission period.

Optionally, the second association order based on the third rule and/or the fourth rule may be a beam scanning resource set identification order, or a beam scanning resource set index order, or a beam scanning resource set configuration order, or a beam scanning resource set time slot offset order. The second association order in which the third rule and the fourth rule are based may be the same or different.

According to the embodiment of the application, the terminal can obtain more information through the first configuration information, so that beam measurement and/or beam prediction can be more effectively performed.

For easy understanding, the technical solution provided by the embodiments of the present application will be described in a specific exemplary manner.

Example one: the first configuration information associates M sets of beam scanning resources, each of the M sets of beam scanning resources or the M sets of beam scanning resources associates N beam scanning resources, on each first window, (UE assumes) the network side device only transmits or only receives at least part of the N beam scanning resources, the first configuration information comprising at least one of: beam report configuration information, beam scanning resource configuration information. Where the (UE assumes) the network side device only transmits or only receives at least part of the N beam scanning resources, there may be two understandings that one is that the network side device directly performs the action, i.e. the network side device only transmits or only receives at least part of the N beam scanning resources, and the other is that the action of the network side device is not limited, and the UE may assume that the network side device performs the action, i.e. the UE assumes the network side device only transmits or only receives at least part of the N beam scanning resources.

Optionally, the parameters used in the beam prediction function in the first window, which are related to the beam prediction input measurement period, may be determined by at least one of protocol convention, network side device configuration, UE reporting, and the like.

Optionally, the first configuration information is associated with a first window and/or a period offset (offset), the period offset (offset) being used to indicate a period offset between the first window and the transmission period.

For example, if the AI model is used to predict beam quality information and/or beam information at a future time or at a future time, and 8 measurements at historical times are required, the number of transmission periods in the first window is equal to 8.

Optionally, the N beam scanning resources correspond to at least one beam scanning resource subset, one beam scanning resource subset associated with at least some of the N beam scanning resources.

Optionally, each subset of beam scanning resources is associated with a transmission period within a first window.

Optionally, the total number of beam scanning resource subsets is equal to the total number of transmission periods within the first window.

Optionally, the periods of the beam scanning resources within the subset of beam scanning resources are the same.

Optionally, the periodicity of the beam scanning resources is different between different subsets of beam scanning resources.

Optionally, the association determining manner of the beam scanning resource subset includes at least one of pre-configuration, signaling indication and pre-set rule convention.

The pre-configuration association refers to pre-associating a beam scanning resource subset directly to each transmission period in each first window;

The signaling indication association refers to additionally indicating a beam scanning resource subset to a first transmission period or a certain transmission period in a first window, and optionally, the rest beam scanning resource subsets are associated with other transmission periods according to a preset rule;

For example, according to the indicated association position, associating with the order of the transmission periods according to the order of the beam scanning resource subsets, there are 8 transmission periods in a first window, and signaling indicates that the beam feedback report corresponding to the first configuration information associates with the second beam scanning resource subset in the first transmission period, and according to the association position, the subsequent association order is to associate with the third beam scanning resource subset in the second transmission period, … …, associate with the eighth beam scanning resource subset in the seventh transmission period, until the first beam scanning resource subset is associated in the eighth transmission period;

The association of the preset rule refers to associating a beam resource scanning subset to each sending period of the beam feedback report corresponding to the first configuration information in the first window according to the preset rule.

Optionally, the sequence corresponding to the preset rule may be a beam resource scanning subset ID sequence, a beam scanning resource subset index sequence, a beam scanning resource subset configuration sequence, a beam scanning resource subset time sequence, a beam scanning resource subset identical slot offset sequence, and the like.

Optionally, when the first configuration information and/or the set of beam scanning resources associated with the first configuration information, the associated time domain characteristic is periodic or semi-persistent:

M＝1；

Or groupBasedBeamReport is not enabled, m=1;

Or groupBasedBeamReport is enabled, M is a contracted value greater than 1, such as m=2.

Optionally, when the N beam scanning resources are associated with the same period and/or the N beam scanning resources are associated with different slot offsets, the interval between two adjacent prediction moments in beam prediction is equal to the period multiplied by the first value beta.

Optionally, the beta value is greater than or equal to 0 and less than or equal to 1;

Optionally, the beta value is determined by at least one of protocol engagement, network side equipment configuration and UE reporting;

Optionally, associating a beta value in the beam feedback report corresponding to the first configuration information;

alternatively, the beta value may be determined by the number of different slot offsets associated in the beam scanning resource having the same period, e.g., beta=1/number of different slot offsets.

For example, 16 beam scanning resources are all configured for 80ms in the same period, but every four beam scanning resources are configured for 1 slot offset, the slot offset corresponding to the 1 st to 4 th beam scanning resources is 0ms, the slot offset corresponding to the 5 th to 8 th beam scanning resources is 20ms, the slot offset corresponding to the 9 th to 12 th beam scanning resources is 40ms, and the slot offset corresponding to the 13 th to 16 th beam scanning resources is 60ms. Beam prediction using AI model, the time interval of adjacent prediction instants should be 20ms instead of 80ms.

Example two: the first configuration information is associated with the P.Q beam scanning resource sets or the P.Q beam scanning resource sets which are activated, and the beam feedback report corresponding to the first configuration information is associated with one beam scanning resource set in each group of beam scanning resource sets in each sending period. On each transmission period, the (UE assumes) network side equipment only transmits or only receives beam scanning resources associated with a beam scanning resource set associated with the current transmission period, and the first configuration information includes at least one of the following: beam report configuration information, beam scanning resource configuration information.

Optionally, the P x Q sets of beam scanning resources are associated with the same period, or the P sets of beam scanning resources within each group of beam scanning resources are associated with the same period.

Optionally, the p×q sets of beam scanning resources or the Q sets of beam scanning resources in each group are associated with beam scanning resources having the same preset order and have one of the following features: period, slot offset position, frequency domain position, bandwidth size, etc.

Optionally, the preset order includes a configuration order, a time domain order, an ID order, an index order, and the like within the beam scanning resource set.

Optionally, the beam scanning resource IDs or indexes associated with the p×q beam scanning resource sets or the Q beam scanning resource sets in each group are different;

P＝1；

Or groupBasedBeamReport is not enabled, p=1;

Or groupBasedBeamReport, P is a contracted value of >1, such as p=2;

I.e. P is the number of groups.

Optionally, the method of associating the beam scanning resource set with the transmission period includes at least one of pre-configuration, signaling indication and pre-set rule convention.

The pre-configuration association refers to pre-associating a beam scanning resource set in each transmission period in a first window directly for a beam feedback report corresponding to the first configuration information;

the signaling indication association refers to that a beam scanning resource set is additionally indicated for a first sending period or a certain sending period of a beam feedback report corresponding to the first configuration information in a first window, and optionally, the rest beam scanning resource sets are associated with other sending periods according to a preset rule;

The association of the preset rule refers to associating a beam scanning resource set according to the preset rule for each sending period of the beam feedback report corresponding to the first configuration information in the first window.

Optionally, the sequence corresponding to the preset rule may be a beam resource scan set ID sequence, a beam scan resource set index sequence, a sequence of beam scan resource set configuration, a beam scan resource set time sequence, a beam scan resource set slot offset sequence, and so on.

When beam prediction is performed using a historical period or a historical measurement resource, a future beam is generally predicted by using a plurality of historical periods or a plurality of historical measurement values through a plurality of historical values.
