Description

Technical Field

[0001] This application relates to the field of wireless communication technologies, and in particular, to an information transmission method, apparatus, device, and storage medium. Background Art

[0002] Currently, in the scenario of artificial intelligence (AI) model inference on the terminal side, even if the terminal's model has a certain generalization ability, the inference performance of the AI model on the terminal side is only excellent under certain specific beam patterns or certain specific numbers of beams. If the measurement resources configured by the base station for the terminal cannot adapt to the terminal's AI model, it will affect the inference performance of the AI model and weaken the performance advantages of AI.

[0003] In addition, in the scenario of AI model prediction on the terminal side, assuming that the beam predicted and output by the AI model is not actually measured by the user equipment (UE), and the network device does not send corresponding measurement resources to the terminal based on the beam predicted and output by the AI model, it will cause the UE to be unable to receive these measurement resources. As a result, the UE will not be able to obtain the quasi-co-location (QCL) parameters of other reference signals or uplink / downlink channels that are quasi-co-located with these measurement resources. Without accurate acquisition of the QCL parameters, the UE will not be able to successfully receive or send the corresponding reference signals or uplink / downlink channels.

[0147] Before introducing the technical solutions of the embodiments of the present application, the related technologies will be introduced first.

[0148] Existing research results show that artificial intelligence (AI) can already obtain corresponding gains in multiple fields such as CSI feedback, beam management, and positioning under the 5G design framework, showing promising application prospects. The current research content includes three use cases of CSI feedback, beam management, and positioning, as well as AI model deployment, inference, update, simulation evaluation methods, etc. A typical use case of AI beam management is spatial beam prediction. AI-enabled spatial beam prediction can predict the L1-reference signal received power (L1-RSRP) of all beam pairs (Set A) by measuring the L1-RSRP of a partial beam pair (Set B) and select the optimal beam to reduce the beam measurement overhead of the terminal.

[0149] Figure 1is a schematic diagram of traditional wave velocity tracking in the related art, as Figure 1 shown. Assume that the base station corresponds to 64 transmitting beams, and the terminal corresponds to 4 receiving beams, which are represented by RX beam1, RX beam2, RX beam3, and RX beam4 respectively. There are 8 CSI-RS reference signals in the periodic resource set configured by the base station. The beam tracking frequency or the reference signal period is 20 ms. In 4 periods, the terminal receives 8 transmitting beams with 4 receiving beams respectively, and obtains the L1-RSRP of 32 beam pairs. The terminal reports the CRI and L1-RSRP of the 4 beam pairs with the largest L1-RSRP, and the base station indicates one of the reference signals to communicate with the terminal.

[0150] Figure 2 is a schematic diagram of AI-based spatial domain beam prediction in the related art, as Figure 2 shown. The implementation method of AI-based spatial domain beam prediction is to first train based on a large dataset. For example, the dataset contains millions of samples, and each sample contains the RSRP of all beam pairs at a certain moment. Secondly, for beam pair prediction, during training, the RSRP of a small number of beam pairs (Set B) is used as the input of the AI model (usually a neural network), and the RSRP of all beam pairs (Set A) is used as the label of the output of the AI model. The parameters in the AI model are continuously updated through the gradient descent algorithm until the error (which can be measured by NMSE) between the output of the AI model and the label is less than the threshold. At this time, the model converges and has good prediction ability. In addition, for transmitting beam prediction, according to a certain receiving beam assumption, during training, the RSRP of a small number of transmitting beams is used as the input of the AI model, and the RSRP of all transmitting beams is used as the label of the output of the AI model. The parameters in the AI model are continuously updated through the gradient descent algorithm until the error between the output of the AI model and the label is less than the threshold.

[0151] Figure 3 is a schematic diagram of AI-based spatial domain beam prediction in the related art, as Figure 3 shown. For AI-based spatial domain beam pair prediction, first collect data for AI model training. The base station needs to scan all 256 beam pairs in the set (Set A) in a short time to prevent the RSRP of different beam pairs from changing over time. The period of Set A can be relatively long. The terminal side does not need to report measurement results during training, while the network side needs to report measurement results.

[0152] Figure 4 is a schematic diagram of AI-based spatial domain beam prediction in the related art, as Figure 4As shown in the figure, inference is performed on the terminal side. For example, the base station configures 8×4 = 32 CSI-RS reference signals (Set B), the reference signal period is 80 ms, and at each moment, the terminal measures the L1-RSRP of 32 beam pairs. The terminal takes the measured 32 L1-RSRPs as the input of the AI model, predicts the L1-RSRP of 256 beam pairs based on the AI model, and the terminal reports the CRI and L1-RSRP of the K beam pairs with the best RSRP. The base station indicates a certain beam pair to communicate with the terminal according to the predicted RSRP value, beam pair load, and other conditions.

[0153] After the terminal infers for a period of time, it needs to collect data for monitoring the model performance. The terminal scans all beam pairs (Set A) with a large period. The terminal or the network compares the error between the optimal beam among all beam pairs (Set A) predicted based on 32 reference signals (Set B) and the true optimal beam among all beam pairs. When the model monitors KPIs, such as the beam prediction accuracy rate is less than the threshold, the terminal or the network triggers model update, switching, or fallback to the traditional beam selection.

[0154] Table 1 is a schematic diagram of the CSI reporting framework in the related art. As shown in Table 1, only one periodic resource set can be configured, with a maximum of 64 reference signals (RS).

[0161] However, existing research shows that in the scenario of terminal-side inference, even if the UE's model has a certain generalization ability, the inference performance of the UE-side AI model is only excellent enough under certain specific beam patterns or certain specific numbers of beams. If the base station cannot know the above specific beam patterns or specific numbers of beams, then the attributes of the RS configured by the base station cannot be adapted to the UE's specific model, which will affect the inference performance of the AI model and weaken the performance advantages of AI.

[0162] In addition, on the other hand, if the beam predicted and output by the AI model is not actually measured by the UE, that is, the predicted beam is the part of beam set Set A that does not overlap with beam set Set B, and the network device does not send corresponding measurement resources to the terminal based on the beam predicted and output by the AI model, it will cause the UE to be unable to obtain the QCL parameters of other reference signals or uplink and downlink channels that are quasi-co-located with them according to the reception of these resources. The QCI parameters may include Doppler shift, Doppler spread, average delay, delay spread, and spatial Rx parameter. Without accurate acquisition of these QCL parameters, the UE cannot smoothly receive or send corresponding reference signals or uplink and downlink channels. One way can be to configure, through RRC, the reference signals corresponding to these predicted beams for the UE to measure, but RRC reconfiguration will significantly increase the measurement delay of the beams, thereby affecting the processing of the corresponding quasi-co-located reference signals and uplink and downlink channels.

[0163] Based on this, in the embodiments of the present application, the terminal sends first information to the network device; wherein, the first information includes at least one of the following: the number of measurement resources; the period of the measurement resources; the frequency domain resources occupied by the measurement resources; the beam characteristics corresponding to the measurement resources.

[0164] In addition, in the embodiments of the present application, the terminal sends second information to the network device; wherein, the second information includes the indexes of K resources; the indexes of the K resources are determined by the terminal for each of the M CSI-RS resources or SSB resources associated with the CSI reporting configuration information, and have an association relationship with a first set associated with the CSI reporting configuration information, and the first set includes P CSI-RS resources or SSB resources, and K, M, and P are all positive integers.

[0165] See Figure 5 , Figure 5 is a schematic implementation process of the information transmission method in the embodiments of the present application, applied to the terminal, as Figure 5 shown, the method includes step 501:

[0166] Step 501: Send first information to the network device;

[0167] Wherein, the first information includes at least one of the following:

[0168] The number of measurement resources;

[0169] The period of the measurement resources;

[0170] The frequency domain resources occupied by the measurement resources;

[0171] The beam characteristics corresponding to the measurement resources.

[0172] As an example, the first information is used for the network device to determine CSI reporting configuration information, or the first information has an association relationship with the CSI reporting configuration information received by the terminal;

[0173] And / or, the first information characterizes the attribute information of the measurement resources expected or supported by the terminal.

[0174] As an example, the measurement resources refer to CSI-RS resources or SSB resources.

[0175] As an example, the terminal can measure the measurement resources to obtain channel quality information, such as L1-RSRP, L1-SINR.

[0176] As an example, the network device can send the measurement resources according to one or more beamforming methods or precoding matrices.

[0177] As an example, the beam characteristics may include the 3dB width of the beam, the normal direction of the beam, the sidelobe direction of the beam, etc.

[0178] As an example, considering that the inference performance of the AI model on the terminal side is excellent enough under certain beam patterns or certain numbers of beams, the terminal can report the attributes of the measurement resources expected or supported to the network device such as the base station.

[0179] In some embodiments, the CSI reporting configuration information is associated with N CSI-RS resources or SSB resources, where N is a positive integer.

[0180] As an example, after the network device such as the base station receives the first information reported by the terminal such as the UE, it can refer to the first information and configure the measurement resources included in the CSI reporting configuration information for the terminal, where the CSI reporting configuration information is associated with N CSI-RS resources or SSB resources for channel measurement.

[0181] In some embodiments, the attributes of the N CSI-RS resources or SSB resources associated with the CSI reporting configuration information are the same as or partially the same as at least one of the attributes of the first information including the number of measurement resources, the period of the measurement resources, the frequency domain resources occupied by the measurement resources, and the beam characteristics corresponding to the measurement resources; or, the attributes of the N CSI-RS resources or SSB resources associated with the CSI reporting configuration information are specific values.

[0182] As an example, the network device such as a base station can configure the CSI reporting configuration information exactly according to the first information reported by the terminal such as a UE.

[0183] For example, assume that the attributes of the expected or supported measurement resources reported by the UE include the number of measurement resources, denoted as M. Then, the number N of CSI-RS resources or SSB resources associated with the CSI reporting configuration information is equal to M.

[0184] Alternatively, assume that the attributes of the expected or supported measurement resources reported by the UE include at least one of the number of measurement resources, the period of measurement resources, the frequency domain resources occupied by the resources, and the beam characteristics corresponding to the measurement resources. Then, the corresponding attributes of the CSI reporting configuration information are equal to or partially equal to the corresponding attributes reported by the UE. For example, if the attributes reported by the UE include the number of measurement resources = A and the period of measurement resources = B, the number of measurement resources associated with the CSI reporting configuration information = A, and the period of measurement resources = C.

[0185] Alternatively, the network device such as a base station can configure the corresponding attributes of the CSI reporting configuration information to a specific value, i.e., a certain special value, to indicate that the corresponding attributes of the terminal CSI reporting configuration information are the same as the attributes of the expected or supported measurement resources reported by the terminal. That is, the network device configures the CSI reporting configuration information according to the first information reported by the terminal, which can effectively reduce the overhead of high-layer configuration signaling. Or, the base station does not configure the corresponding attributes, indicating that the base station configures the CSI reporting configuration information completely according to the corresponding attributes reported by the UE.

[0186] In some embodiments, the method further includes:

[0187] Receiving the CSI reporting configuration information sent by the network device.

[0188] In some embodiments, the first information is sent to the network device through one of the following:

[0189] The capability reporting information of the terminal;

[0190] PUSCH;

[0191] PUCCH;

[0192] CSI reporting information;

[0193] MAC CE.

[0194] The embodiments of the present application have the following advantages:

[0195] (1) The terminal sends the first information to the network device; wherein, the first information includes at least one of the following: the number of measurement resources; the period of the measurement resources; the frequency-domain resources occupied by the measurement resources; the beam characteristics corresponding to the measurement resources. The terminal reports the attribute information of the measurement resources that it expects or supports, i.e., the first information, to the network device. In this way, the network device can configure the measurement resources included in the CSI reporting configuration information according to the attribute information of the measurement resources that the terminal expects or supports. Subsequently, the terminal uses the configured measurement resources for AI model inference, which helps to improve the inference performance of the AI model.

[0196] (2) By enabling the terminal to report the attribute information of the measurement resources that it expects or supports, i.e., the first information, to the network device, it is equivalent to implicitly reporting the relevant information of the AI model on the terminal side to the network device, which can help the network device configure specific measurement resources for the terminal according to the characteristics of the AI model on the UE side. Subsequently, the beam prediction accuracy based on the AI model can be maximally improved.

[0202] the period of the measurement resources;

[0203] the frequency-domain resources occupied by the measurement resources;

[0204] the beam characteristics corresponding to the measurement resources.

[0205] As an example, the first information is used for the network device to determine the CSI reporting configuration information, or the first information has an association relationship with the CSI reporting configuration information received by the terminal;

[0206] and / or, the first information represents the attribute information of the measurement resources that the terminal expects or supports.

[0207] As an example, the measurement resources refer to CSI-RS resources or SSB resources.

[0208] As an example, the terminal can obtain channel quality information, such as L1-RSRP and L1-SINR, by measuring the measurement resources.

[0209] As an example, the network device can send the measurement resources according to one or more beamforming methods or precoding matrices.

[0210] As an example, the beam characteristics may include the 3dB width of the beam, the normal direction of the beam, the sidelobe direction of the beam, etc.

[0211] As an example, considering that the inference performance of the AI model on the terminal side is excellent enough under certain beam patterns or certain numbers of beams, the terminal can report the attributes of the expected or supported measurement resources to the network device such as the base station.

[0212] In some embodiments, the CSI reporting configuration information is associated with N CSI-RS resources or SSB resources, where N is a positive integer.

[0213] As an example, after receiving the first information reported by the terminal such as UE, the network device such as the base station can refer to the first information to configure CSI reporting configuration information for the terminal, where the CSI reporting configuration information is associated with N CSI-RS resources or SSB resources for channel measurement.

[0214] In some embodiments, the attributes of the N CSI-RS resources or SSB resources associated with the CSI reporting configuration information are the same as or partially the same as at least one of the attributes of the first information including the number of measurement resources, the period of the measurement resources, the frequency domain resources occupied by the measurement resources, and the beam characteristics corresponding to the measurement resources; or the attributes of the N CSI-RS resources or SSB resources associated with the CSI reporting configuration information are set to specific values.

[0215] As an example, the network device such as the base station can configure the CSI reporting configuration information exactly according to the first information reported by the terminal such as UE.

[0216] For example, assuming that the attributes of the expected or supported measurement resources reported by the UE include the number of measurement resources, and the number is denoted as M, then the number N of the CSI-RS resources or SSB resources associated with the CSI reporting configuration information is equal to M.

[0217] Alternatively, assuming that at least one of the number of measurement resources, the period of the measurement resources, the frequency domain resources occupied by the resources, and the beam characteristics corresponding to the measurement resources is included in the attributes of the expected or supported measurement resources reported by the UE, the corresponding attributes of the CSI reporting configuration information are equal to or partially equal to the corresponding attributes reported by the UE. For example, if the attributes reported by the UE include the number of measurement resources = A, the period of the measurement resources = B, the number of measurement resources associated with the CSI reporting configuration information = A, and the period of the measurement resources = C.

[0218] Alternatively, the network device such as a base station may configure the corresponding attributes of the CSI reporting configuration information to a specific value, i.e., a certain special value, to indicate that the corresponding attributes of the terminal CSI reporting configuration information are the same as the attributes of the expected or supported measurement resources reported by the terminal. That is, the network device configures the CSI reporting configuration information according to the first information reported by the terminal, which can effectively reduce the high-layer configuration signaling overhead. Or, the base station does not configure the corresponding attributes, indicating that the base station configures the CSI reporting configuration information completely according to the corresponding attributes reported by the UE.

[0219] In some embodiments, the method further includes:

[0220] Sending the CSI reporting configuration information to the terminal.

[0221] In some embodiments,

[0222] Receiving the first information sent by the terminal through one of the following:

[0223] The capability reporting information of the terminal;

[0224] PUSCH;

[0225] PUCCH;

[0226] CSI reporting information;

[0227] MAC CE.

[0228] The embodiments of the present application have the following advantages:

[0229] (1) The terminal sends the first information to the network device; wherein, the first information includes at least one of the following: the number of measurement resources; the period of the measurement resources; the frequency domain resources occupied by the measurement resources; the beam characteristics corresponding to the measurement resources. The terminal reports the attribute information of the expected or supported measurement resources, i.e., the first information, to the network device. In this way, the network device can configure the measurement resources included in the CSI reporting configuration information according to the attribute information of the measurement resources expected or supported by the terminal, and subsequently the terminal uses the configured measurement resources for AI model inference, which helps to improve the inference performance of the AI model.

[0230] See Figure 7, Figure 7 This is a schematic flowchart of the implementation of the information transmission method in an embodiment of the present application, which is applied to a terminal. As Figure 7 shown, the method includes step 701:

[0231] Step 701: Send second information to a network device;

[0232] Among them, the second information includes indexes of K resources; the indexes of the K resources are determined by the terminal based on each of the M CSI-RS resources or SSB resources associated with CSI reporting configuration information, and have an association relationship with a first set associated with the CSI reporting configuration information. The first set includes P CSI-RS resources or SSB resources, and K, M, and P are all positive integers.

[0233] In some instances, the method further includes:

[0234] Receive third information sent by the network device; the third information is used to indicate the resources for the terminal to perform measurements;

[0235] Among them,

[0236] the third information includes a second set; the second set includes at least one resource different from the M CSI-RS resources or SSB resources associated with the CSI reporting configuration information among the K resources.

[0237] In some embodiments, the receiving the third information sent by the network device includes:

[0238] Receive the third information sent by the network device after CSI reporting;

[0239] Or,

[0240] Trigger or activate the reception of the third information through a first DCI or a first MAC CE.

[0241] In some instances, the CSI reporting configuration information is determined by the network device based on fourth information sent by the terminal;

[0242] Among them,

[0243] the fourth information includes at least one of the following:

[0244] The number of measurement resources;

[0245] The period of the measurement resources;

[0246] The frequency domain resources occupied by the measurement resources;

[0247] The beam characteristics corresponding to the measurement resources.

[0248] In some examples, the fourth information characterizes the attribute information of the measurement resources expected or supported by the terminal.

[0249] In some examples, the method further includes:

[0250] receiving fifth information sent by the network device; the fifth information is used to characterize the resources for the terminal to perform measurements;

[0251] wherein, the fifth information includes the K resources.

[0252] In some embodiments, the receiving the fifth information sent by the network device includes:

[0253] receiving the fifth information sent by the network device after CSI reporting;

[0254] Or,

[0255] triggering or activating the reception of the fifth information through a second DCI or a second MAC CE.

[0256] As an example, the CSI reporting configuration configured by the network device for the UE is associated with a predicted resource set, i.e., the first set, wherein the first set includes P CSI-RS resources or SSB resources (P≥1).

[0257] As an example, through a first model on the terminal side, the results (such as the channel quality RSRP) obtained from each of the M CSI-RS resources or SSB resources associated with the measurement CSI reporting configuration information can be used as the input of the first model, and the indexes (beam indexes) of the predicted K resources are output through the first model, wherein the first model may refer to an AI model. Meanwhile, optionally, the first model may also additionally output information such as the RSRP corresponding to the predicted resources.

[0258] As an example, the UE determines the beams of the K optimal resources based on the configured measurement resources.

[0259] As an example, the UE reports the indexes of the K resources, and each resource index occupies bits, where P represents the total number of resources in the first set. The resource index equal to 0 corresponds to the first resource in the predicted resource set, the resource index equal to 1 corresponds to the second resource in the predicted resource set, and so on.

[0260] Suppose the resources corresponding to the indices of K resources are represented by {resource#1, resource#2, …, resource#k}, where at least one resource does not belong to the M CSI-RS resources for channel measurement associated with the CSI reporting configuration information, and this at least one resource is denoted as resource set #A, i.e., the second set. There are {resource#1, resource#2, …, resource#n} in resource set #A. If the terminal actually does not measure the resources in this resource set #A, the terminal cannot obtain the QCL parameters of other reference signals or uplink and downlink channels that are quasi-co-located with these resources based on the reception of these resources. The QCI parameters may include Doppler shift, Doppler spread, average delay, delay spread, and spatial reception parameter. Without accurate acquisition of these QCL parameters, the terminal cannot smoothly receive or transmit the corresponding reference signals or uplink and downlink channels. One way may be to configure the resources in resource set #A for the terminal through RRC configuration and let the terminal measure them, but this will significantly increase the measurement delay of the beam, thereby affecting the processing of the corresponding reference signals and uplink and downlink channels.

[0261] In the embodiments of the present application, the following solutions are provided:

[0262] The first way is to receive the third information sent by the network device after CSI reporting; the third information includes the second set.

[0263] Here, receiving the third information sent by the network device after CSI reporting may include:

[0264] In the case where the second set is configured as aperiodic, receiving the third information sent by the network device based on the time slot interval corresponding to the second set configured by RRC;

[0265] Or,

[0266] In the case where the second set is configured as semi-persistent, receiving the third information sent by the network device based on the number of time slots of the subcarrier interval parameter corresponding to the second set configured by RRC; the number of time slots is the number of time slots in a subframe;

[0267] Or,

[0268] When the second set is configured to be semi-persistent or periodic, receive the third information sent by the network device based on the transmission mode corresponding to the second set configured by RRC; the transmission mode includes the frequency domain position occupied by the resource, the transmission time slot interval, and the transmission period.

[0269] Specifically, the terminal can trigger the network device to send resource set #A, that is, the second set, to the terminal by sending the second information through the CSI reporting process, and record the time of CSI reporting as slot n.

[0270] If the second set configured by the network device is aperiodic, and the slot offset configured by the network device through RRC = d, the terminal will receive resource set #A, that is, the second set, in the first slot after slot n + d.

[0271] If the second set configured by the network device is semi-persistent, the terminal will start receiving resource set #A, that is, the second set, in the first slot after slot n + 3×N slotsubframe,μ where n represents the slot in which the terminal performs CSI reporting, and N slotsubframe,μ represents the number of slots in a subframe corresponding to the subcarrier spacing parameter μ, and μ is the subcarrier spacing parameter corresponding to the subcarrier spacing (SCS, Sub-Carrier Spacing) configuration of the PUSCH or PUCCH carried by the CSI reporting.

[0272] If the second set configured by the network device is semi-persistent or periodic, the network device configures the transmission mode (pattern) of the second set through RRC, where the transmission mode includes the frequency domain position occupied by the resource, the transmission time slot interval (slot offset), the transmission period, etc.; then, the network device sends the second set in the (n + T)-th slot after slot n, and the (n + T) is the timing of the first transmission of the second set after slot n, and T is a positive integer, and T is related to the transmission mode. That is to say, the network device sends the reference signal in resource set #A, that is, the second set, at the transmission occasion of the nearest CSI-RS after slot n, and the terminal receives the second set at the above occasion.

[0273] The second method is to receive the fifth information sent by the network device after CSI reporting; the fifth information includes K resources.

[0274] Here, receiving the third information sent by the network device after CSI reporting may include:

[0275] When the second set is configured as aperiodic, receiving the third information sent by the network device based on the slot interval corresponding to the second set configured by RRC;

[0276] Or,

[0277] When the second set is configured as semi-persistent, receiving the third information sent by the network device based on the number of time slots corresponding to the subcarrier spacing parameter of the second set configured by RRC; the number of time slots is the number of time slots in a subframe;

[0278] Or,

[0279] When the second set is configured as semi-persistent or periodic, receiving the third information sent by the network device based on the transmission mode corresponding to the second set configured by RRC; the transmission mode includes the frequency domain position occupied by the resource, the transmission slot interval, and the transmission period.

[0280] Specifically, the terminal sending the second information to the network device through the CSI reporting process may trigger the network device to send these K optimal resources to the terminal.

[0281] If the K resources configured by the network device are aperiodic and the configured slot offset = d, then the UE will receive these K resources in the first slot after slot n + d;

[0282] If the K resources configured by the network device are semi-persistent, the terminal will start receiving these K resources in the first slot after slot n + 3×N slotsubframe,μ After that, N slotsubframe,μ Represents the number of time slots in a subframe corresponding to the subcarrier spacing parameter μ, and μ is the subcarrier spacing parameter corresponding to the SCS configuration of the PUSCH or PUCCH carried by the CSI report.

[0283] If the K resources configured by the network device are semi-persistent or periodic, the network device can also configure the transmission pattern of the K resources through RRC. Among them, the transmission pattern includes the frequency domain position occupied by the resources, the transmission slot offset, the transmission period, etc. Then, the network device transmits the K resources in the (n + T)-th slot after slot n. The (n + T)-th slot is the opportunity to transmit the K resources for the first time after slot n. T is a positive integer, and T is related to the transmission pattern. That is to say, the network device transmits the reference signal among the K resources at the transmission occasion of the nearest CSI-RS after slot n, and the terminal receives the K resources at the above occasion.

[0284] In the third way, the reception of the third information is triggered or activated through the first DCI or the first MAC CE; the third information includes the second set.

[0285] Here, triggering or activating the reception of the third information through DCI or MAC CE may include:

[0286] When the second set is configured as aperiodic, after receiving the DCI sent by the network device, based on the slot offset corresponding to the second set configured by RRC, receive the third information sent by the network device;

[0287] Or,

[0288] When the second set is configured as semi-persistent, after receiving the MAC CE sent by the network device, based on the number of slots corresponding to the subcarrier spacing parameter of the second set configured by RRC, receive the third information sent by the network device; the number of slots is the number of slots in a subframe;

[0289] Or,

[0290] When the second set is configured as semi-persistent, after receiving the DCI sent by the network device, based on the slot offset corresponding to the second set configured by RRC, receive the third information sent by the network device.

[0291] Specifically, a network device such as a base station, based on the received CSI report, sends a DCI or a MAC CE to activate or trigger the transmission of the resource set #A, that is, the second set.

[0292] If the second set configured by the network device is aperiodic, triggered by DCI, and the slot offset configured by the network device through RRC = d, and the transmission time of the DCI is denoted as n, then the UE will receive the resource set #A, i.e., the second set, in the first slot after slot n + d;

[0293] If the second set configured by the network device is semi-persistent, activated by MAC CE, and the transmission time of the PUCCH carrying HARQ-ACK corresponding to the PDSCH carrying this MAC CE is denoted as n, then the UE will start receiving the resource set #A, i.e., the second set, in the first slot after slot n + 3×N slotsubframe,μ where N slotsubframe,μ represents the number of slots in a subframe corresponding to the subcarrier spacing parameter μ, and μ is the subcarrier spacing parameter corresponding to the SCS configuration of the PUSCH or PUCCH carried by the CSI report.

[0294] If the second set configured by the network device is semi-persistent, activated by DCI, and the configured slot offset = d, and the transmission time of the DCI is denoted as n, then the UE will receive the resource set #A, i.e., the second set, in the first slot after slot n + d.

[0295] In the fourth method, the reception of the fifth information is triggered or activated through a second DCI or a second MAC CE; the fifth information includes K resources.

[0296] Here, the network device, such as a base station, based on the received CSI report, sends a DCI or a MAC CE to directly activate or trigger the transmission of these K optimal resources, and the specific triggering or activation time relationship is the same as that in the third method.

[0297] In the embodiments of the present application, the following advantages are achieved:

[0298] (1) The terminal sends second information to the network device; the second information includes the indexes of K resources; the K resources are determined based on each of the M CSI-RS resources or SSB resources associated with the CSI reporting configuration information, and have an association relationship with a first set associated with the CSI reporting configuration information, the first set includes P CSI-RS resources or SSB resources, and K, M, and P are all positive integers. In this way, the network device can indicate the resources for the terminal to measure according to the second information, avoiding the problem that in the related art, when at least one of the K resources does not belong to the M CSI-RS resources or SSB resources associated with the CSI reporting configuration information, the terminal cannot measure these resources. Subsequently, the terminal can obtain the QCL parameters of other reference signals or the uplink and downlink channels that are quasi-co-located with these resources according to the reception of these resources, and then successfully receive or send the corresponding reference signals or uplink and downlink channels.

[0299] (2) When the UE does not measure the beam predicted by the AI model, through a flexible UE trigger / activation or base station trigger / activation method, the transmission and measurement of the corresponding reference signal of the predicted beam are quickly triggered / activated, reducing the delay of beam measurement, improving the reception or transmission accuracy of the reference signal and the uplink and downlink channels, and ensuring the system throughput.
