[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese Patent Application No. 202410028950.9 filed in China on January 8, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to the field of wireless communication technologies, and in particular to an information transmission method, apparatus, device, and storage medium. Background Art

[0004] Currently, in the scenario of terminal-side artificial intelligence (AI) model inference, even if the terminal model has a certain generalization capability, the inference performance of the terminal-side AI model is only good enough under certain specific beam modes or certain specific numbers of beams. If the measurement resources configured by the base station for the terminal cannot adapt to the AI ​​model of the terminal, it will affect the inference performance of the AI ​​model and weaken the performance advantage of AI.

[0005] In addition, in the scenario of terminal-side AI model prediction, 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 the corresponding measurement resources to the terminal based on the beam predicted and output by the AI ​​model, the UE will 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 and downlink channels that are quasi-co-located with them based on these measurement resources. Without accurate acquisition of the QCL parameters, the UE cannot successfully receive or send the corresponding reference signals or uplink and downlink channels. Summary of the Invention

[0149] Before introducing the technical solutions of the embodiments of the present disclosure, the relevant technologies are first introduced.

[0150] Existing research results show that artificial intelligence (AI) has achieved corresponding gains in multiple fields such as CSI feedback, beam management, and positioning within the design framework of the fifth generation mobile communication technology (5G), showing considerable application prospects. Current research content includes three major use cases: CSI feedback, beam management, and positioning, as well as AI model deployment, reasoning, updating, simulation and evaluation methods. A typical use case of AI beam management is spatial beam prediction. AI-enabled spatial beam prediction can measure the Layer 1 reference signal received power (L1-RSRP) of some beam pairs (Set B), predict the L1-RSRP of all beam pairs (Set A), and select the optimal beam to reduce terminal beam measurement overhead.

[0151] Figure 1 is a schematic diagram of traditional beam tracking in the related art. As shown in Figure 1, it is assumed that the base station corresponds to 64 transmit beams and the terminal corresponds to 4 receive beams, represented by RX beam 1, RX beam 2, RX beam 3 and RX beam 4 respectively. The base station configures a periodic resource set with 8 CSI-RS reference signals. The beam tracking frequency or reference signal period is 20ms. In 4 periods, the terminal uses 4 receive beams to receive 8 transmit beams respectively, obtaining 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. The base station indicates one of the reference signals to communicate with the terminal.

[0152] FIG2 is a schematic diagram of AI-based spatial beam prediction in the related art. As shown in FIG2 , the implementation method of AI-based spatial beam prediction is to first perform training based on a large dataset, for example, a dataset containing millions of samples, each sample containing the RSRP of all beam pairs at a certain moment. Second, for beam pair prediction, the RSRP of a small number of beam pairs (Set B) is used as the input of an AI model (usually a neural network) during training, and the RSRP of all beam pairs (Set A) is used as the label output by the AI ​​model. The parameters within the AI ​​model are continuously updated using the gradient descent algorithm until the error between the AI ​​model output and the label (which can be measured by the Normalized Mean Squared Error (NMSE)) is less than a threshold. At this point, the model converges and has good prediction capabilities. In addition, for transmit beam prediction, according to a certain receive beam assumption, the RSRP of a small number of transmit beams is used as the input of the AI ​​model during training, and the RSRP of all transmit beams is used as the label output by the AI ​​model. The parameters within the AI ​​model are continuously updated using the gradient descent algorithm until the error between the AI ​​model output and the label is less than a threshold.

[0153] Figure 3 is a schematic diagram of AI-based spatial beam prediction in related art. As shown in Figure 3, for AI-based spatial beam pair prediction, data is first collected for AI model training. The base station must scan the set of all 256 beam pairs (Set A) within a short period of time to prevent RSRP of different beam pairs from varying over time. The Set A period can be relatively long. Terminal-side training does not require reporting of measurement results, but network-side training does.

[0154] Figure 4 is a schematic diagram of AI-based spatial beam prediction in the related art. As shown in Figure 4, reasoning is performed on the terminal side. For example, the base station configures 8×4=32 CSI-RS reference signals (Set B) with a reference signal period of 80ms. At each moment, the terminal measures the L1-RSRP of 32 beam pairs. The terminal uses the measured 32 L1-RSRP as the AI ​​model input and predicts the L1-RSRP of 256 beam pairs based on the AI ​​model. The terminal reports the CRI and L1-RSRP of the K beam pairs with the best RSRP. The base station instructs one of the beam pairs to communicate with the terminal based on the predicted RSRP value and beam pair load.

[0155] After a period of inference, the terminal needs to collect data to monitor model performance. The terminal scans all beam pairs (Set A) at a relatively high rate. The terminal or network compares the error between the optimal beam predicted from all beam pairs (Set A) based on 32 reference signals (Set B) and the actual optimal beam from all beam pairs. When a key performance indicator (KPI) monitored by the model, such as beam prediction accuracy falling below a threshold, the terminal or network triggers a model update, switches, or reverts to traditional beam selection.

[0156] Table 1 is a schematic diagram of a CSI reporting framework in related art. As shown in Table 1, only one periodic resource set can be configured, which contains a maximum of 64 reference signals (RSs).

[0157] Table 1

[0158] Table 2 is a schematic diagram of CSI-RS resource set configuration in related technologies.

[0159] Table 2

[0160] However, existing research shows that in terminal-side inference scenarios, even if the UE model has a certain degree of generalization capability, the UE-side AI model's inference performance is only good enough under certain specific beam patterns or a certain number of beams. If the base station cannot know these specific beam patterns or a specific number of beams, then the reference signal (RS) attributes configured by the base station will not be able to adapt to the specific UE model, which will affect the inference performance of the AI ​​model and weaken the performance advantage of AI.

[0161] On the other hand, if the beam predicted by the AI ​​model is not actually measured by the UE, that is, the predicted beam is the portion of beam set Set A that does not overlap with beam set Set B, and the network device does not send the corresponding measurement resources to the terminal based on the beam predicted by the AI ​​model, the UE will not be able to obtain the QCL parameters of other reference signals or uplink and downlink channels that are quasi-co-located with it based on the reception of these resources. QCL parameters may include Doppler shift, Doppler spread, average delay, delay spread, and spatial receive parameters. Without accurate acquisition of these QCL parameters, the UE will not be able to successfully receive or send the corresponding reference signals or uplink and downlink channels. One way to do this is to configure the UE with the reference signals corresponding to these predicted beams through Radio Resource Control (RRC) configuration, allowing the UE to measure them. However, RRC reconfiguration will significantly increase the measurement delay of the beam, thereby affecting the processing of the corresponding quasi-co-located reference signals and uplink and downlink channels.

[0162] Based on this, in an embodiment of the present disclosure, 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 measurement resources; the frequency domain resources occupied by the measurement resources; and the beam characteristics corresponding to the measurement resources.

[0163] In addition, in an embodiment of the present disclosure, the terminal sends second information to the network device; wherein, the second information includes indexes of K resources; the indexes of the K resources are determined by the terminal based on each resource of the M CSI-RS resources or SSB resources associated with the CSI reporting configuration information, and have an association relationship with the 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.

[0164] 5 , which is a schematic diagram of an implementation flow of an information transmission method according to an embodiment of the present disclosure, and is applied to a terminal. As shown in FIG5 , the method includes step 501:

[0165] Step 501: Sending first information to a network device;

[0166] The first information includes at least one of the following:

[0167] the number of measurement resources;

[0168] Measuring resource cycles;

[0169] The frequency domain resources occupied by the measurement resources;

[0170] Measure the beam characteristics corresponding to the resource.

[0171] As an example, the first information is used by the network device to determine CSI reporting configuration information, or the first information is associated with the CSI reporting configuration information received by the terminal;

[0172] And / or, the first information represents attribute information of measurement resources expected or supported by the terminal.

[0173] As an example, the measurement resource refers to a CSI-RS resource or an SSB resource.

[0174] As an example, the terminal may obtain channel quality information, such as L1-RSRP and Layer 1 Signal to Interference plus Noise Ratio (L1-SINR), by measuring the measurement resource.

[0175] As an example, the network device may send the measurement resource according to one or more beamforming modes or precoding matrices.

[0176] As an example, the beam characteristics may include a 3 dB width of the beam, a normal direction of the beam, a side lobe direction of the beam, and the like.

[0177] As an example, considering that the reasoning performance of the AI ​​model on the terminal side is sufficiently good 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 a base station.

[0178] In some embodiments, the CSI reporting configuration information is associated with N CSI-RS resources or SSB resources, where N is a positive integer.

[0179] As an example, after the network device such as a base station receives the first information reported by the terminal such as a UE, it can refer to the first information to configure the measurement resources contained in the CSI reporting configuration information for the terminal, wherein the CSI reporting configuration information is associated with N CSI-RS resources or SSB resources for channel measurement.

[0180] In some embodiments, the attributes of the N CSI-RS resources or SSB resources associated with the CSI reporting configuration information are the same or partially the same as the attributes of at least one of the first information, including the number of measurement resources, the period of 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.

[0181] As an example, the network device such as a base station may configure the CSI reporting configuration information completely according to the first information reported by the terminal such as a UE.

[0182] For example, assuming that the attributes of the expected or supported measurement resources reported by the UE include the number of measurement resources, which is recorded as M, then the number N of CSI-RS resources or SSB resources associated with the CSI reporting configuration information is equal to M.

[0183] Alternatively, assuming 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, 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.

[0184] Alternatively, the network device such as a base station can configure the corresponding attribute of the CSI reporting configuration information to a specific value, i.e., a special value, to indicate that the corresponding attribute of the terminal CSI reporting configuration information is the same as the attribute of the expected or supported measurement resource 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-level configuration signaling overhead, or the base station does not configure the corresponding attribute, indicating that the base station configures the CSI reporting configuration information completely according to the corresponding attribute reported by the UE.

[0185] In some embodiments, the method further comprises:

[0186] Receive the CSI reporting configuration information sent by the network device.

[0187] In some embodiments, the first information is sent to the network device by one of the following:

[0188] Terminal capability reporting information;

[0189] PUSCH;

[0190] PUCCH;

[0191] CSI reporting information;

[0192] MAC CE.

[0193] The embodiments of the present disclosure have the following advantages:

[0194] (1) 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; and 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. The terminal subsequently uses the configured measurement resources to perform AI model inference, which helps to improve the inference performance of the AI ​​model.

[0195] (2) By enabling the terminal to report the attribute information of the expected or supported measurement resources, that is, 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 targeted and specific measurement resources for the terminal according to the characteristics of the AI ​​model on the UE side, thereby maximizing the beam prediction accuracy based on the AI ​​model in the future.

[0202] The frequency domain resources occupied by the measurement resources;

[0203] Measure the beam characteristics corresponding to the resource.

[0204] As an example, the first information is used by the network device to determine CSI reporting configuration information, or the first information is associated with the CSI reporting configuration information received by the terminal;

[0205] And / or, the first information represents attribute information of measurement resources expected or supported by the terminal.

[0206] As an example, the measurement resource refers to a CSI-RS resource or an SSB resource.

[0207] As an example, the terminal may obtain channel quality information, such as L1-RSRP and L1-SINR, by measuring the measurement resource.

[0208] As an example, the network device may send the measurement resource according to one or more beamforming modes or precoding matrices.

[0209] As an example, the beam characteristics may include a 3 dB width of the beam, a normal direction of the beam, a side lobe direction of the beam, and the like.

[0210] As an example, considering that the reasoning performance of the AI ​​model on the terminal side is sufficiently good 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 a base station.

[0211] In some embodiments, the CSI reporting configuration information is associated with N CSI-RS resources or SSB resources, where N is a positive integer.

[0212] As an example, after the network device such as a base station receives the first information reported by the terminal such as a UE, it can refer to the first information to configure CSI reporting configuration information for the terminal, wherein the CSI reporting configuration information is associated with N CSI-RS resources or SSB resources for channel measurement.

[0213] In some embodiments, the attributes of the N CSI-RS resources or SSB resources associated with the CSI reporting configuration information are the same or partially the same as the attributes of at least one of the first information, including the number of measurement resources, the period of 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.

[0214] As an example, the network device such as a base station may configure the CSI reporting configuration information completely according to the first information reported by the terminal such as a UE.

[0215] For example, assuming that the attributes of the expected or supported measurement resources reported by the UE include the number of measurement resources, which is recorded as M, then the number N of CSI-RS resources or SSB resources associated with the CSI reporting configuration information is equal to M.

[0216] Alternatively, assuming 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, 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.

[0217] Alternatively, the network device such as a base station can configure the corresponding attribute of the CSI reporting configuration information to a specific value, i.e., a special value, to indicate that the corresponding attribute of the terminal CSI reporting configuration information is the same as the attribute of the expected or supported measurement resource 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-level configuration signaling overhead, or the base station does not configure the corresponding attribute, indicating that the base station configures the CSI reporting configuration information completely according to the corresponding attribute reported by the UE.

[0218] In some embodiments, the method further comprises:

[0219] Sending the CSI reporting configuration information to the terminal.

[0220] In some embodiments,

[0221] The first information sent by the terminal is received by one of the following methods:

[0222] Terminal capability reporting information;

[0223] PUSCH;

[0224] PUCCH;

[0225] CSI reporting information;

[0226] MAC CE.

[0227] The embodiments of the present disclosure have the following advantages:

[0228] (1) 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; and 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. The terminal subsequently uses the configured measurement resources to perform AI model inference, which helps to improve the inference performance of the AI ​​model.

[0229] 7 , which is a schematic diagram of an implementation flow of an information transmission method according to an embodiment of the present disclosure, and is applied to a terminal. As shown in FIG7 , the method includes step 701:

[0230] Step 701: Sending second information to the network device;

[0231] 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 the CSI reporting configuration information, and are associated with the first set associated with the CSI reporting configuration information, the first set containing P CSI-RS resources or SSB resources, and K, M, and P are all positive integers.

[0232] In some examples, the method further comprises:

[0233] receiving third information sent by the network device; the third information is used to indicate resources for the terminal to measure;

[0234] in,

[0235] The third information includes a second set; the second set includes at least one resource among the K resources that is different from the M CSI-RS resources or SSB resources associated with the CSI reporting configuration information.

[0236] In some embodiments, the receiving the third information sent by the network device includes:

[0237] receiving the third information sent by the network device after the CSI is reported;

[0238] or,

[0239] The reception of the third information is triggered or activated through the first DCI or the first MAC CE.

[0240] In some instances, the CSI reporting configuration information is determined by the network device based on fourth information sent by the terminal;

[0241] in,

[0242] The fourth information includes at least one of the following:

[0243] the number of measurement resources;

[0244] Measuring resource cycles;

[0245] The frequency domain resources occupied by the measurement resources;

[0246] Measure the beam characteristics corresponding to the resource.

[0247] In some examples, the fourth information represents attribute information of measurement resources desired or supported by the terminal.

[0248] In some examples, the method further comprises:

[0249] receiving fifth information sent by the network device, wherein the fifth information is used to represent resources measured by the terminal;

[0250] The fifth information includes the K resources.

[0251] In some embodiments, the receiving fifth information sent by the network device includes:

[0252] receiving the fifth information sent by the network device after the CSI is reported;

[0253] or,

[0254] The reception of the fifth information is triggered or activated through the second DCI or the second MAC CE.

[0255] As an example, the CSI reporting configuration configured by the network device for the UE is associated with a predicted resource set, namely the first set, where the first set includes P CSI-RS resources or SSB resources (P≥1).

[0256] As an example, the first model on the terminal side can be used to measure the results of each of the M CSI-RS resources or SSB resources associated with the CSI reporting configuration information (such as channel quality RSRP) as the input of the first model, and the first model outputs the predicted indexes of the K resources (beam indexes), wherein the first model can refer to an AI model. At the same time, optionally, the first model can also additionally output information such as RSRP corresponding to the predicted resources.

[0257] As an example, the UE determines K optimal resource beams based on the configured measurement resources.

[0258] As an example, the UE reports the indexes of K resources, each resource index occupies bits, where P represents the total number of resources in the first set, a resource index equal to 0 corresponds to the first resource in the predicted resource set, a resource index equal to 1 corresponds to the second resource in the predicted resource set, and so on.

[0259] If the resources corresponding to the indexes of K resources are represented by {resource#1, resource#2, ..., resource#k}, and 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 recorded as resource set #A, i.e., the second set, and resource set #A contains {resource#1, resource#2, ..., resource#n}, if the terminal does not actually measure the resources in this resource set #A, the terminal will not be able to 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. QCL parameters may include Doppler shift, Doppler spread, average delay, delay spread, and spatial Rx parameters. Without accurate acquisition of these QCL parameters, the terminal will not be able to successfully receive or send the corresponding reference signals or uplink and downlink channels. One way may be to configure the terminal with resources in resource set #A 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 signal and uplink and downlink channels.

[0260] In the embodiments of the present disclosure, the following solutions are provided:

[0261] The first way is to receive the third information sent by the network device after the CSI is reported; the third information includes the second set.

[0262] Here, receiving the third information sent by the network device after the CSI is reported may include:

[0263] When the second set is configured as aperiodic, receiving the third information sent by the network device based on a time slot interval corresponding to the second set configured by RRC;

[0264] or,

[0265] 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 of the subcarrier spacing parameter corresponding to the second set configured by RRC; the number of time slots is the number of time slots in a subframe;

[0266] or,

[0267] When the second set is configured as semi-continuous or periodic, the third information sent by the network device is received based on the transmission mode corresponding to the second set configured by RRC; the transmission mode includes the frequency domain position occupied by the resources, the transmission time slot interval, and the transmission period.

[0268] Specifically, the terminal sends the second information to the network device through the CSI reporting process, which can trigger the network device to send resource set #A, that is, the second set, to the terminal, and record the time of CSI reporting as time slot (slot) n.

[0269] If the second set configured by the network device is aperiodic, and the slot offset configured by the network device through RRC is d, the terminal will receive resource set #A, i.e., the second set, in the first slot after slot n+d.

[0270] If the second set of network equipment configurations is semi-persistent, the terminal will be in time slot n+3×N slotsubframe,μ The first time slot after that starts to receive resource set #A, i.e., the second set, where n represents the time slot for the terminal to report CSI, N slotsubframe,μ Indicates the number of time slots in a subframe corresponding to the subcarrier spacing parameter μ, where μ is the subcarrier spacing parameter corresponding to the subcarrier spacing (SCS) configuration of the PUSCH or PUCCH carried by the CSI report.

[0271] If the second set configured by the network device is semi-continuous or periodic, the network device configures the transmission pattern of the second set through RRC, where the transmission pattern includes the frequency domain position occupied by the resource, the transmission slot offset, the transmission period, etc.; then, the network device transmits the second set in the n+Tth time slot after time slot n, where n+Tth is the first time the second set is transmitted after time slot n, and T is a positive integer, and T is associated with the transmission pattern. In other words, the network device transmits resource set #A, i.e., the reference signal in the second set, at the most recent CSI-RS transmission occasion after time slot n, and the terminal receives the second set at the above occasion.

[0272] The second method is to receive the fifth information sent by the network device after the CSI is reported; the fifth information includes K resources.

[0273] Here, receiving the third information sent by the network device after the CSI is reported may include:

[0274] When the second set is configured as aperiodic, receiving the third information sent by the network device based on a time slot interval corresponding to the second set configured by RRC;

[0275] or,

[0276] 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 of the subcarrier spacing parameter corresponding to the second set configured by RRC; the number of time slots is the number of time slots in a subframe;

[0277] or,

[0278] When the second set is configured as semi-continuous or periodic, the third information sent by the network device is received based on the transmission mode corresponding to the second set configured by RRC; the transmission mode includes the frequency domain position occupied by the resources, the transmission time slot interval, and the transmission period.

[0279] Specifically, the terminal sends the second information to the network device through the CSI reporting process, which can trigger the network device to send the K optimal resources to the terminal.

[0280] If the K resources configured by the network device are non-periodic and the configured slot offset is d, then the UE will receive these K resources in the first slot after slot n + d.

[0281] If the K resources configured by the network device are semi-persistent, the terminal will be in time slot n+3×N slotsubframe,μ The first time slot after that starts to receive these K resources, N slotsubframe,μ Indicates the number of time slots in a subframe corresponding to the subcarrier spacing parameter μ, where μ is the subcarrier spacing parameter corresponding to the SCS configuration of the PUSCH or PUCCH carried by the CSI report.

[0282] 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, where the transmission pattern includes the frequency domain location occupied by the resource, the transmission slot offset, the transmission period, etc. The network device then transmits the K resources in the n+Tth time slot after time slot n, where n+Tth is the first transmission opportunity of the K resources after time slot n, and T is a positive integer associated with the transmission pattern. In other words, the network device transmits the reference signal in the K resources at the most recent CSI-RS transmission occasion after time slot n, and the terminal receives the K resources at this occasion.

[0283] The third way is to trigger or activate the reception of the third information through the first DCI or the first MAC CE; the third information includes the second set.

[0284] Here, triggering or activating the reception of the third information through the DCI or MAC CE may include:

[0285] When the second set is configured as aperiodic, after receiving the DCI sent by the network device, receiving the third information sent by the network device based on the time slot interval corresponding to the second set configured by RRC;

[0286] or,

[0287] When the second set is configured as semi-persistent, after receiving the MAC CE sent by the network device, receiving the third information sent by the network device based on the number of time slots of the subcarrier spacing parameter corresponding to the second set configured by RRC; the number of time slots is the number of time slots in a subframe;

[0288] or,

[0289] In the case where the second set is configured as semi-persistent, after receiving the DCI sent by the network device, the third information sent by the network device is received based on the time slot interval corresponding to the second set configured by RRC.

[0290] Specifically, a network device such as a base station sends a DCI or MAC CE based on the received CSI report to activate or trigger the sending of resource set #A, that is, the second set.

[0291] If the second set configured by the network device is aperiodic, triggered by DCI, and the network device configures a slot interval (slotoffset) = d through RRC, and the DCI transmission time is recorded as n, then the UE will receive resource set #A, i.e., the second set, in the first slot after slot n+d;

[0292] If the second set configured by the network device is semi-persistent, it is activated by MAC CE, and the sending time of the PUCCH carrying HARQ-ACK corresponding to the PDSCH carrying the MAC CE is recorded as n, then the UE will be in time slot (slot) n+3×N slotsubframe,μ The first time slot after that starts to receive resource set #A, i.e. the second set, N slotsubframe,μ Indicates the number of time slots in a subframe corresponding to the subcarrier spacing parameter μ, where μ is the subcarrier spacing parameter corresponding to the SCS configuration of the PUSCH or PUCCH carried by the CSI report.

[0293] If the second set configured by the network device is semi-continuous, activated by DCI, and the configured time slot interval (slotoffset) = d, and the sending time of DCI is recorded as n, then the UE will receive resource set #A, i.e. the second set, in the first time slot after time slot (slot) n+d.

[0294] The fourth method is to trigger or activate the reception of the fifth information through a second DCI or a second MAC CE; the fifth information includes K resources.

[0295] Here, the network device such as the base station sends a DCI or MAC CE based on the received CSI report to directly activate or trigger the sending of the K optimal resources. The specific triggering or activation time relationship is the same as the third method.

[0296] The embodiments of the present disclosure have the following advantages:

[0297] (1) The terminal sends a second information to the network device; the second information includes indexes of K resources; the K resources are determined by the terminal based on each of the M CSI-RS resources or SSB resources associated with the CSI reporting configuration information, and are associated with the first set associated with the CSI reporting configuration information, the first set including P CSI-RS resources or SSB resources, K, M, and P are all positive integers, so that the network device can indicate the terminal to measure resources according to the second information, thereby avoiding the problem in the related art that 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, resulting in the terminal being unable to measure these resources. The subsequent terminal can 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, and then successfully receive or send the corresponding reference signals or uplink and downlink channels.

[0298] (2) When the UE fails to measure the beam predicted by the AI ​​model, the transmission and measurement of the corresponding reference signal of the predicted beam can be quickly triggered / activated through flexible UE triggering / activation or base station triggering / activation methods, thereby reducing the delay of beam measurement, improving the reception or transmission accuracy of the reference signal and uplink and downlink channels, and ensuring system throughput.
