First, the content related to this application is introduced.

(1) Beam measurement and reporting (beam measurement and beam reporting)

The analog beamforming is transmitted in full bandwidth, and each polarization element on the panel of each high-frequency antenna array can only transmit analog beams in a time-division multiplexed manner. The shaping weight of the analog beam is realized by adjusting the parameters of the RF front-end phase shifter and other equipment.

At present, in academia and industry, the training of analog beamforming vectors is usually carried out in a polling manner, that is, the array elements of each polarization direction of each antenna panel are sequentially sent training signals at the appointed time in a time-division multiplexing manner ( That is, the candidate shaping vector), the terminal feeds back the beam report after the measurement, and the network side uses the training signal to realize the simulated beam transmission in the next service transmission. The content of the beam report usually includes several optimal transmit beam identities and the measured received power of each transmit beam.

When performing beam measurement, the network will configure a reference signal resource set (RS resource set), which includes at least one reference signal resource, such as a synchronization signal block (Synchronization Signal and PBCH Block, SSB) resource or a channel state information reference signal (Channel State Information-Reference Signal, CSI-RS) resources. The UE measures the Layer 1 reference signal received power (Layer 1 reference signal received power, L1- RSRP)/Layer 1 signal-to-noise and interference ratio (Layer 1 signal-to-noise and interference ratio, L1-SINR), and at least one optimal measurement result is reported to the network, and the reported content includes the synchronization signal block resource indicator (SSB Resource Indicator, SSBRI) or channel state information reference signal resource indicator (Channel State Information Reference Signal Resource Indicator, CRI), and L1-RSRP/L1-SINR. The content of the report reflects at least one optimal beam and its quality, and is used by the network side to determine the beam used to send the channel or signal to the UE.

(2) beam indication mechanism

After beam measurement and beam reporting, the network can make beam indications for downlink and uplink channels or reference signals, which are used to establish beam links between the network and UE to realize the transmission of channels or reference signals.

For the beam indication of the Physical Downlink Control Channel (PDCCH), the network uses Radio Resource Control (RRC) signaling to configure K transmission configuration indications for each control resource set (CORESET) (Transmission Configuration Indication, TCI) state, when K>1, the media access control layer control unit (Media Access Control Control Unit, MAC CE) indicates or activates a TCI state, when K=1, no additional MAC CE command. When the UE monitors the PDCCH, it uses the same quasi-colocation (QCL) for all the search spaces in the CORESET, that is, the same TCI state to monitor the PDCCH. The reference signal (for example, periodic CSI-RS resource, semi-persistent CSI-RS resource, SS block, etc.) in the TCI state is spaced with the UE-specific (UE-specific) PDCCH demodulation reference signal (demodulation reference signal, DMRS) port QCL's. The UE can know which receiving beam to use to receive the PDCCH according to the TCI state.

For physical downlink shared channel (Physical downlink shared channel, PDSCH) beam indication, the network configures M TCI states through RRC signaling, then uses MAC CE commands to activate 2N TCI states, and then passes downlink control information (Downlink control information, DCI ) to notify the TCI status, the reference signal in the TCI status is QCL with the DMRS port of the PDSCH to be scheduled. The UE can know which receiving beam to use to receive the PDSCH according to the TCI state.

For CSI-RS beam indication, when the CSI-RS type is periodic CSI-RS, the network configures QCL information for CSI-RS resources through RRC signaling. When the CSI-RS type is semi-persistent CSI-RS, the network indicates its QCL information when activating a CSI-RS resource from the CSI-RS resource set configured by RRC through a MAC CE command. When the CSI-RS type is aperiodic CSI-RS, the network configures QCL for the CSI-RS resource through RRC signaling, and uses DCI to trigger the CSI-RS.

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

For the beam indication of the Physical Uplink Shared Channel (PUSCH), the spatial relationship information of the PUSCH is when the DCI carried by the PDCCH schedules the PUSCH, the sounding reference signal resource indication in the DCI Each SRI code point (codepoint) in the SRS resource indicator (SRI) field indicates an SRI, and the SRI is used to indicate the spatial relationship information of the PUSCH.

For the beam indication of the Sounding reference signal (Sounding reference signal, SRS), when the SRS type is periodic SRS, the network configures spatial relationship information for the SRS resource through RRC signaling. When the SRS type is semi-persistent SRS, the network activates one from a set of spatial relationship information configured by RRC through a MAC CE command. When the SRS type is aperiodic SRS, the network configures the spatial relationship information for the SRS resource through RRC signaling.

For further beam indication improvement, a unified TCI indication (unified TCI indication) is proposed, which simply means to indicate the beam information of subsequent reference signals and multiple channels through the TCI field in a DCI.

(3) Beam indication-free mechanism

The above-mentioned beam indication mechanism needs to be interacted through signaling. After the interaction is completed, the beam can take effect, which leads to a high delay in beam switching. Especially in some high-speed scenarios, beams are frequently switched, and the delay in signaling interaction may be Does not meet demand.

In order to reduce the beam switching delay, a beam indication-free mechanism is proposed. The beam indication-free mechanism refers to beam information that does not need to be used interactively on the network side and the terminal side. A feasible solution is that artificial intelligence (AI) models with the same type or function exist at the same time on the terminal and the network side. By feeding back the measurement information and the output results of the AI model on one side, the other side also passes through the AI model. Obtain the output result of the AI model, and the output result is consistent on both sides, so there is no need to further interact with the beam information used. In this way, beam indication can be avoided and delay can be reduced.

It should be noted that the above is only a feasible solution, and is not limited to the implementation of the beam indication-free mechanism in this solution.

Possible modes of the beam indication-free mechanism include:

Mode 1: Terminal B feeds back the output results of the AI model at terminal B, and terminal A and/or terminal B use the information related to the output results of the AI model for information transmission.

Specific possible steps include: B-terminal measurement and feedback, and B-terminal feedback information includes B-terminal AI model output related information, after A-terminal receives B-terminal feedback information, A-terminal and/or B-terminal can directly use B-terminal The information related to the output result of the AI model is used for subsequent information transmission, or the A terminal uses the A terminal AI model to output the relevant information of the result and the B terminal uses the B terminal AI model to output the relevant information of the result for subsequent information transmission.

Mode 2: Terminal B feeds back information about the output results of the AI model at terminal B, and terminal A adjusts and/or calibrates and/or verifies the parameters of the AI model at terminal A.

Specific possible steps include: B-side measurement and feedback, and B-side feedback information includes B-side AI model output related information, after A-side receives B-side feedback information, A-side uses B-side feedback information for adjustment/calibration A terminal AI model parameters, and/or verification/calibration whether the information related to the output results of the A terminal AI model is the same or similar to that of the B terminal AI model output results, or the error is within a certain range.

Optionally, at this time, terminal A may additionally feed back error results or confirm whether the results are consistent, or when the error range exceeds a preset limit, feedback error results or notify terminal B that the error exceeds the range.

Mode 3: Terminal B feeds back the measurement results to Terminal A, Terminal A feeds back information related to the output results of the AI model to Terminal B, and Terminal A and/or Terminal B use the information related to the output results of the AI model for information transmission.

Specific possible steps include: B-side measurement and feedback, but the B-side feedback information does not include information related to the B-side AI model output results, or the B-side feedback information only includes real measurement information, and the A-side uses the B-side feedback information to pass After the A-side AI model is obtained, relevant information about the output results of the A-side AI model is obtained. The A-side and/or B-side can directly use the relevant information of the A-side AI model output results for subsequent information transmission, or the A-side uses the A-side AI model to output results. Relevant information and the B-side uses the B-side model to output relevant information for subsequent information transmission.

Mode 4: Terminal B feeds back the measurement results to Terminal A, Terminal A feeds back the output results of the AI model to Terminal B, and Terminal B adjusts and/or calibrates and/or verifies the model parameters of Terminal B

Specific possible steps include: B-side measurement and feedback, but B-side feedback does not include B-side AI model output related information, or B-side feedback information only includes real measurement information, A-side based on B-side feedback information, through A After the terminal AI model, obtain the relevant information about the output results of the A terminal AI model, and feed back the relevant information about the output results of the A terminal AI model to the B terminal, and the B terminal is used to adjust/calibrate the parameters of the B terminal model, and/or verify/calibrate the B terminal AI model Whether the information related to the output result is the same or similar to the information related to the output result of the A-end model, or whether the error is within a certain range.

Optionally, at this time, terminal B can additionally feed back error results or confirm whether the results are consistent, or when the error range exceeds a preset limit, feedback error results or notify terminal A that the error exceeds the range.

Wherein, device A is one of the following: a terminal, a network side device, and an auxiliary network central unit, and device B is one of the following: a terminal, a network side device, and an auxiliary network central unit. Wherein, the auxiliary network central unit is a unit for information interaction, and can communicate with terminals and network side devices.

(4) AI model

Artificial Intelligence (AI) has been widely used in various fields. There are many ways to implement AI models, such as neural networks, decision trees, support vector machines, Bayesian classifiers, etc. The embodiment of the present application uses a neural network as an example for illustration, but does not limit the specific type of the AI model. The neural network is composed of neurons, where a ₁ , a ₂ ,...a _K is the input, w is the weight (multiplicative coefficient), b is the bias (additive coefficient), and σ(.) is the activation function. Common activation functions include Sigmoid, tanh, Rectified Linear Unit (ReLU), etc. The parameters of the neural network are optimized by an optimization algorithm. An optimization algorithm is a class of algorithms that can help us minimize or maximize an objective function (sometimes called a loss function). The objective function is often a mathematical combination of model parameters and data. For example, given the data X and its corresponding label Y, we construct a neural network model f(.), with the model, the predicted output f(x) can be obtained according to the input x, and the predicted value and the real value can be calculated The gap between (f(x)-Y), this is the loss function. Our purpose is to find the appropriate w, b to minimize the value of the above loss function, the smaller the loss value, the closer our model is to the real situation.

The current common optimization algorithms are basically based on the BP (error Back Propagation, error back propagation) 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 forward propagation, the input samples are passed in from the input layer, processed layer by layer by each hidden layer, and passed to the output layer. If the actual output of the output layer does not match the expected output, it will enter the error backpropagation stage. Error backpropagation is to transmit the output error layer by layer through the hidden layer to the input layer in some form, and distribute the error to all the units of each layer, so as to obtain the error signal of each layer unit, and this error signal is used as the correction unit Basis for weight. The forward propagation of the signal and the backpropagation of the error The weight adjustment process of each layer is carried out repeatedly. The process of continuously adjusting the weights is also the learning and training process of the network. This process has been carried out until the error of the network output is reduced to an acceptable level, or until the preset number of learning times.

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

These optimization algorithms are based on the error/loss obtained by the loss function when the error is backpropagated, and the derivative/partial derivative of the current neuron is calculated, and the learning rate, the previous gradient/derivative/partial derivative, etc. are added to obtain the gradient. Pass the gradient to the previous layer.

(5) Beam indication effective time

The beam corresponding to the PDCCH indicates the effective time. If the UE receives the MAC CE activation command to indicate one of the TCI states of 0, the UE takes effect of the activation command from The first slot after that starts, where k is the time slot for the UE to send a PUCCH with HARQ-ACK for the PDSCH to provide an activation command (that is, the HARQ-ACK of the activated MAC CE), μ is the subcarrier spacing of the PDCCH (sub -carrier space, SCS). The activated bandwidth part (Bandwidth part, BWP) is the BWP defined to be activated on the time slot in which the activation command takes effect.

The effective time of beam indication corresponding to PDCCH, the effective time of MAC-CE activation, the effective time of PUCCH with HARQ/ACK (corresponding to PDSCH, the activation command carried by MAC CE) in slot n, that is, the mapping between TCI state and DCI TCI field relationship is valid In the first time slot after , μ is the SCS of the PUCCH, that is, the MAC CE activation command takes effect 3ms after the corresponding HARQ/ACK.

The beam corresponding to the DCI indicates the effective time. If tci-PresentInDCI is enabled or tci-PresentDCI-1-2 is configured in the CORESET that schedules the PDSCH, the time offset between the received DCI and the scheduled PDSCH should be greater than or equal to timeDurationForQCL (if reported this parameter).

If the scheduled DCI carried by the PDCCH is received on one CC, and the scheduled PDSCH is received on another CC, that is, during cross-carrier scheduling, timeDUrationForQCL is determined according to the SCS of the scheduled PDSCH. If μ _PDCCH < μ _PDSCH , you need to add an additional timing to timeDurationForQCL When μ _PDCCH =0 or 1, d=8, and when μ _PDCCH =2, d=14.
