[0164] In some embodiments, the apparatus and device may be interpreted as physical or virtual, and their names are not limited to the names recorded in the embodiments. In some cases, they may also be understood as "equipment", "device", "circuit", "network element", "node", "function", "unit", "section", "system", "network", "chip", "chip system", "entity", "body", etc.

[0165] In some embodiments, the acquisition of data, information, etc., may comply with the laws and regulations of the country where the location is situated. In some embodiments, data, information, etc., may be acquired with the user's consent.

[0166] In some embodiments, the channel information is downlink channel information, which is determined by the terminal device based on a channel measurement reference signal. The channel measurement reference signal can be, for example, a channel state information reference signal (CSI-RS) or a demodulation reference signal (DMRS). In this embodiment, the example of a CSI-RS channel measurement reference signal is used for illustration.

[0167] In some embodiments, a moment can also be referred to as a slot, meaning that a single moment can be defined in units of slots. In some embodiments, moments and slots can be used interchangeably.

[0168] Currently, in the field of communications, terminal devices can receive X CSI-RS at X historical moments. For each historical moment, channel information is determined based on the received CSI-RS to obtain channel measurement information for X historical moments. Further, the obtained X channel information is input into an Artificial Intelligence (AI) model. The AI ​​model predicts the channel measurement information at the X historical moments to output channel prediction information for M future moments. The terminal device can then determine Channel State Information (CSI) based on the channel prediction information for the M future moments and send the CSI to the network device. Here, X and M are integers greater than or equal to 1.

[0169] In some embodiments, the time window containing X historical moments can be called the observation window, and the time window containing M future moments can be called the prediction window.

[0170] The observation window and prediction window are illustrated below with reference to Figure 1a.

[0171] Figure 1a is an exemplary schematic diagram of the observation window and prediction window according to an embodiment of this disclosure. As shown in Figure 1a, the observation window includes X historical moments, and the prediction window includes M future moments. In the observation window, the time-domain interval between two adjacent historical moments is C time slots. In the prediction window, the time-domain interval between two adjacent future moments is D time slots.

[0172] In some embodiments, X can be 4, 5, 8, 10, etc. In some embodiments, when the network device configures aperiodic CSI-RS (AP CSI-RS) for the terminal device, X can be 4, 8, 12, and C can be 2.

[0173] In some embodiments, C can be 2, 3, 4, 5, etc.

[0174] In some embodiments, M can be 1, 3, 4, etc.

[0175] In some embodiments, D can be 1, 2.5, 4, 5, 8, etc. Wherein, the length w of the prediction window... d Satisfy: w d =M×D.

[0176] It is worth noting that Figure 1a is illustrated using X=4, C=4, M=4, and D=4 as an example. It should be understood that other exemplary schematic diagrams of observation windows and prediction windows can also be obtained using other values ​​of X, C, M, and D.

[0177] In some embodiments, the timing of the channel prediction information for M future moments predicted by the AI ​​model can be either before the prediction window or within the observation window.

[0178] In some embodiments, the terminal device may send the CSI to the network device before or after the observation window.

[0179] For example, the channel prediction information for M future moments predicted by the AI ​​model is before the prediction window. The terminal device can determine the CSI based on the channel prediction information for M future moments and send the CSI to the network device.

[0180] In some scenarios, the channel of the terminal device may change. If the channel prediction information of M future moments is used to determine the CSI using AI model prediction, the accuracy of the CSI may be low. Therefore, it is necessary to test the prediction performance of the AI ​​model.

[0181] Currently, intermediate Key Performance Indicators (KPIs) can be used to measure the predictive performance of AI models. These intermediate KPIs include Square Generalized Cosine Similarity (SGCS) and / or Normalized Mean Square Error (NMSE).

[0182] It is worth noting that, for a future moment, a channel measurement information shall include at least: the actual feature vectors of each of the R resource elements at that future moment.

[0183] It is worth noting that, for a future time, a channel prediction information includes at least: the prediction feature vectors of R resource elements at that future time.

[0184] In some embodiments, a future moment can correspond to an SGCS. For example, an SGCS that can correspond to a future moment can be represented as:

[0185] Where SGCS0 represents the cosine similarity at a future time, R can represent the total number of resource units at that future time, and w r w′ can represent the actual feature vector corresponding to the r-th resource unit at that future time. r Let w represent the predicted feature vector corresponding to the r-th resource unit at that future time, where ||| denotes the norm symbol. r It was not predicted by an AI model, w′ r It was predicted using an AI model.

[0186] In some embodiments, the resource element may be a preset number of resource blocks (RBs), a preset number of subcarriers, or subbands, etc. For example, the preset number may be 1, 2, 3, etc.

[0187] In some embodiments, multiple future moments can correspond to a single SGCS. For example, a single SGCS that can correspond to multiple future moments can be represented by the following formula 1:

[0188] Here, SGCS1 represents the SGCS corresponding to multiple future moments, and E represents the expectation operation.

[0189] In some embodiments, a future time point can correspond to an NMSE. For example, an NMSE corresponding to a future time point can be represented as:

[0190] In some embodiments, multiple future moments can correspond to a single NMSE. For example, an NMSE that can correspond to multiple future moments can be represented as:

[0191] According to formulas 1 to 4 above, in order to obtain SGCS or NMSE, w must first be obtained. r In other words, the terminal device needs to first receive the CSI-RS, and then determine w based on the CSI-RS. r So how does the terminal device receive CSI-RS to ensure that the CSI-RS is received at a future moment, thereby enabling w′ r and w r Correspondingly, improving the accuracy of intermediate KPIs is a technical problem that urgently needs to be solved.

[0192] To address the aforementioned issues, this disclosure provides a communication method, apparatus, device, system, storage medium, and program product. The method provided in this disclosure allows network devices to send CSI-RS at a future time, and terminal devices to receive CSI-RS at a future time, ensuring that the terminal device receives the CSI-RS at a future time. This helps improve the accuracy of intermediate KPIs, thereby enhancing the accuracy of monitoring AI models.

[0202] The communication methods, apparatus, devices, systems, storage media, and program products provided in this disclosure will now be described in detail with reference to the accompanying drawings.

[0203] Figure 2a is an exemplary flowchart of a communication method provided according to an embodiment of the present disclosure. As shown in Figure 2a, the method includes the following steps:

[0204] In step S2101, the network device sends downlink control information (DCI) to the terminal device. The DCI is used to trigger the terminal device to send CSI.

[0205] In step S2102, the terminal device determines the CSI based on the channel prediction information corresponding to each of the M time points predicted and output by the AI ​​model.

[0206] In some embodiments, the terminal device is equipped with an AI model.

[0207] The AI ​​model can output (or infer) M time points and the corresponding channel prediction information for each of the M time points. The M time points can include N first time points, where N is an integer greater than or equal to 1 and M is an integer greater than or equal to N.

[0208] The M times can be predefined times or times indicated by the network device to the terminal device.

[0209] In some embodiments, when M times are times indicated by the network device, the network device can obtain M times through one or more of the following: Radio Resource Control (RRC) signaling, Medium Access Control-Control Element (MAC CE) signaling, DCI, or terminal device reporting indication.

[0210] In some embodiments, the M time points are the times within the prediction window of the AI ​​model's inference. The M time points can be referred to as the M prediction times or the M future times.

[0211] The N first moments are the moments used to monitor the AI ​​model. The first moment can also be called the monitoring moment, etc.

[0212] Step S2103: The terminal device sends a CSI to the network device.

[0213] In step S2104, the network device sends N channel measurement reference signals to the terminal device at N first moments out of M moments. Correspondingly, the terminal device receives N channel measurement reference signals at the N first moments.

[0214] In other words, at N first moments, the network device sends N channel measurement reference signals to the terminal device based on N channel measurement resources, where one of the N channel measurement resources corresponds to one first moment. In other words, at the first moment where the N channel measurement resources are located, the network device sends N channel measurement reference signals to the terminal device based on the N channel measurement resources.

[0215] N first moments can be understood as the moments in which N channel measurement resources are located, where one channel measurement resource is located at one first moment.

[0216] In some embodiments, the N channel measurement resources may be the same or different.

[0217] In some embodiments, the N channel measurement resources are different, and the N channel measurement resources can be aperiodic resources.

[0218] In some embodiments, when the N channel measurement resources are aperiodic resources, the N channel measurement resources are used to transmit N channel measurement reference signals.

[0219] In some embodiments, N channel measurement resources are identical (i.e., 1 channel measurement resource), which can be a periodic resource or a semi-persistent resource.

[0220] In some embodiments, when the channel measurement resource is a periodic resource or a semi-persistent resource, one channel measurement resource is used to transmit N channel measurement reference signals.

[0221] In some embodiments, the channel measurement resource can be a CSI-RS resource, and the channel measurement reference signal can be a CSI-RS.

[0222] In some embodiments, the transmission mode of the channel measurement reference signal can be aperiodic transmission, periodic transmission, or semi-persistent transmission.

[0223] In some embodiments, the N first moments are determined according to one or more of the following:

[0224] The second moment is the transmission moment of DCI. DCI is used to trigger the terminal device to send CSI. CSI is determined by the channel prediction information corresponding to each of the M moments predicted by the AI ​​model. The M moments include the N first moments, and M is an integer greater than or equal to N.

[0225] The first time offset between the second time point and the reference time point;

[0226] The second time offset between the reference time and each of the N first times;

[0227] The third moment is the first moment among the M moments;

[0228] The fourth moment is when the terminal device sends the CSI.

[0229] The fifth moment is the moment when the terminal device sends monitoring information.

[0230] In some embodiments, the channel measurement reference signal may be transmitted periodically or semi-continuously.

[0231] In some embodiments, CSI can be transmitted in an aperiodic, periodic, or continuous manner.

[0232] In some embodiments, the transmission method of monitoring information from the AI ​​model can be non-periodic, periodic, or continuous. In other words, the reporting of monitoring information can be non-periodic, periodic, or semi-continuous.

[0233] In some embodiments, DCI can also be used to trigger non-periodic reporting of monitoring information.

[0234] In some embodiments, DCI triggering is not required when the monitoring information is reported periodically.

[0235] In some embodiments, when the reporting of monitoring information is semi-continuous, MAC-CE or DCI triggering is required.

[0236] In some embodiments, the transmission time of DCI can be the time when the network device sends DCI, or the time when the terminal device receives DCI.

[0237] In some embodiments, the channel measurement reference signal is transmitted in an aperiodic manner;

[0238] The N channel measurement reference signals are signals transmitted through N reference signal resources;

[0239] The N reference signal resources are contained in a non-periodic set of reference signal resources;

[0240] The DCI is also used to trigger the aperiodic reference signal resource set.

[0241] Aperiodic reference signal resource set can also be called aperiodic resource set.

[0242] In some embodiments, the second moment may also be referred to as the moment when the DCI triggers the aperiodic reference signal resource set.

[0243] In some embodiments, the aperiodic reference signal resource set includes at least N reference signal resources.

[0244] In some embodiments, the aperiodic reference signal resource set may be an aperiodic CSI-RS resource set, which includes at least N CSI-RS resources, at least N reference signal resources being at least those N CSI-RS resources, and N channel measurement reference signals being N CSI-RS.

[0245] In some embodiments, the channel measurement reference signal is transmitted in a periodic or semi-continuous manner.

[0246] The N channel measurement reference signals are reference signals transmitted through one reference signal resource;

[0247] The reference signal resource is contained in a periodic or semi-persistent set of reference signal resources.

[0248] In some embodiments, the periodic reference signal resource set may also be referred to as the periodic resource set.

[0249] In some embodiments, the semi-persistent reference signal resource set may also be referred to as the semi-persistent resource set.

[0250] In some embodiments, the periodic or semi-persistent set of reference signal resources includes one reference signal resource.

[0251] In some embodiments, the periodic or semi-persistent reference signal resource set is a periodic or semi-persistent CSI-RS Resource Set, which includes one CSI-RS Resource, one reference signal resource is at least the one CSI-RS Resource, and N channel measurement reference signals are N CSI-RS.

[0252] In this embodiment of the disclosure, the design scheme of the first time offset can be shown in Examples 1A-1C below.

[0253] Example 1A: The first time offset is a predefined time offset. This can be understood as the terminal device having pre-written or pre-stored the first time offset.

[0254] Example 1B: The network device sends a first indication information to the terminal device, the first indication information being used to indicate a first time offset.

[0255] Example 1C: The terminal device determines the first time offset based on the second time and the reference time.

[0256] The following examples, 2A and 2B, illustrate the design scheme for determining the first time offset based on the second and third time points.

[0257] Example 2A: The first time offset O, the second time t1, and the reference time t0 satisfy the formula: O = t0 - t1.

[0258] Example 2B: The first time offset O, the second time t1, and the reference time t0 satisfy the formula: O = max(t0-t1, 0); where max represents the maximum value operation.

[0259] In some embodiments, the reference time t0 and the third time t2 satisfy the formula: t0=t2+(m-1)×D; where m represents the index of the first first time in the M times among the N first times, D represents the time interval between two adjacent times among the M times, and m is an integer, 1≤m≤M.

[0260] Based on Example 2A, the first time offset O, the second time t1, and the third time t2 satisfy the formula: O=t2+(m-1)×D-t1; where m is an integer, 1≤m≤M.

[0261] In some embodiments, when the third time t2 is after the second time t1, O = t2 + (m-1) × D - t1.

[0262] When O = t2 + (m-1) × D - t1, m can be a value configured by the network device for the terminal device, or m can be a predefined value.

[0263] In other words, based on Example 2A, if the predicted m-th time is taken as the monitoring time (i.e., the first time), and the first time (i.e., the third time) in the predicted time obtained by the AI ​​model inference is after the time when the reference signal resource set for the DCI triggering aperiodicity is located (i.e., the second time), then O = t2 + (m-1) × D - t1.

[0264] Based on Example 2B, the first time offset O, the second time t1, and the third time t2 satisfy the formula: O = max(t2 + (m-1) × D - t1, 0); where m is an integer, 2 ≤ m ≤ M. For example, m can be the minimum value among 2 to M.

[0265] In some embodiments, when t2 is before t1 and t1 is before the last of the M time points, O = max(t2 + (m-1) × D - t1, 0).

[0266] When O = max(t2 + (m-1) × D - t1, 0), if O is 0, the first first moment among the N first moments is the moment that is after t1 and most recently predicted among the M moments.

[0267] When O = max(t2 + (m-1) × D - t1, 0), m can be a value configured by the network device for the terminal device, or m can be a predefined value that makes (t2 + (m-1) × D - t1) > 0.

[0268] In other words, based on Example 2B, if the predicted m-th moment is used as the monitoring moment (i.e., the first moment), when the first moment among the prediction moments obtained by AI model inference (i.e., the first moment among the M moments, i.e., the third moment) is located before the moment where the DCI triggers the aperiodic reference signal resource set (i.e., the second moment), and the moment where the DCI triggers the aperiodic reference signal resource set (i.e., the second moment) is located before the last moment among the prediction moments obtained by AI model inference (i.e., the last moment among the M moments), then O=max(t2+(m-1)×D-t1,0).

[0269] FIG. 3a is a schematic diagram of an example of the positional relationship between the second moment t1 and the third moment t2 provided by the embodiments of the present disclosure. As shown in FIG. 3a, the third moment t2 is located after the second moment t1, and the third moment t2 is the first moment among the M moments.

[0270] FIG. 3b is a schematic diagram of an example of the positional relationship between the second moment t1 and the third moment t2 provided by the embodiments of the present disclosure. As shown in FIG. 3b, the third moment t2 is located before the second moment t1, and the third moment t2 is the first moment among the M moments.

[0271] In some embodiments, the fourth moment t3 may be located between the third moments t2. For example, in FIG. 3a, t3 is located between t1 and t2. For example, in FIG. 3b, t3 is located before t2.

[0272] In some embodiments, the fourth moment t3 may be used to determine the third moment t2.

[0273] For example, the aperiodic CSI-RS Resource Set includes 1 (i.e., N=1) CSI-RS Resource, the third moment t2 is located after the second moment t1, if m=1, the first time offset O satisfies: O=t2-t1. Wherein, m=1 indicates that the CSI-RS indicated by the CSI-RS Resource is used to obtain monitoring information of one moment (M=1) output by the AI model, or obtain monitoring information of the first moment among multiple moments (1<M) output by the AI model.

[0274] In other words, if the network device and the terminal device determine through negotiation and predefinition that the CSI-RS Resource is used to monitor one moment / slot predicted by the AI model, or the first moment / slot among multiple moments / slots predicted by the AI model, then the offset value O of the aperiodic resource set satisfies O=t2-t1.

[0275] For example, M=4, the aperiodic CSI-RS Resource Set includes 1 (i.e., N=1) CSI-RS Resource, and the third time t2 is after the second time t1. If m=M, then the first time offset O satisfies: O=t2+(M-1)×D-t1=t2+3D-t1. The following example illustrates this with M=4 and D=2 time slots. Here, m=M indicates that the CSI-RS indicated by this CSI-RS Resource is used to obtain the monitoring information of the last of the M time slots output by the AI ​​model.

[0276] In other words, if the interval between two adjacent times / slots in M=4 times / slots is D=2 timeslots, and if the terminal device is predefined to monitor the last time / slot obtained by AI inference, then when the first time in the predicted time obtained by AI model inference (i.e., the first time in M ​​times, i.e., the third time) is after the time when the reference signal resource set for the DCI triggering aperiodicity is located (i.e., the second time), the offset value of the aperiodic resource set is O=t2+(M-1)×D-t1=t2+3D-t1.

[0277] Figure 3c is a schematic diagram of a prediction output of the AI ​​model when m = M according to an embodiment of this disclosure. As shown in Figure 3c, M = 4, D = 2, and the third time t2 is after the second time t1.

[0278] The non-periodic CSI-RS Resource Set includes one CSI-RS Resource, which indicates a CSI-RS used to obtain monitoring information at the m-th (m=M) time. The first time offset O satisfies: O=t2+3D-t1.

[0279] For example, an aperiodic CSI-RS Resource Set includes 1 (i.e., N=1) CSI-RS Resource. The third time t2 is before the second time t1. The CSI-RS indicated by this CSI-RS Resource is used to obtain the monitoring information of the AI ​​model output at a certain time. This time is after the second time t1 and the closest time to the second time t1. Then the first time offset O satisfies: O=0.

[0280] For example, M=4, the aperiodic CSI-RS Resource Set includes 1 (i.e., N=1) CSI-RS Resource, and the third time t2 is after the second time t1. If m=3, then the first time offset O satisfies: O=max(t2+(m-1)×D-t1,0)=t2+(M-1)×D-t1=t2+2D-t1. m=3 indicates that the CSI-RS indicated by this CSI-RS Resource is used to obtain monitoring information for the third time after the second time t1 out of M times.

[0281] Figure 3d is a schematic diagram of a prediction output of the AI ​​model when m=3 according to an embodiment of this disclosure. As shown in Figure 3c, M=4, D=2, and the third time t2 is before the second time t1.

[0282] The non-periodic CSI-RS Resource Set includes one CSI-RS Resource. The CSI-RS indicated by this CSI-RS Resource is used to obtain the monitoring information at the m-th (m=3) time after the second time t1. The first time offset O satisfies: O=max(t2+(m-1)×D-t1,0)=t2+(M-1)×D-t1=t2+2D-t1.

[0283] In some embodiments, the second time offset between the reference time and each of the N first times can also be understood as the second time offset between the aperiodic CSI-RS Resource Set and each of the N CSI-RS Resources, wherein the aperiodic CSI-RS Resource Set includes at least N CSI-RS Resources, and one first time corresponds to one CSI-RS Resource.

[0284] In some embodiments, the second time offset may also be referred to as the time offset of the CSI-RS Resource or the offset value.

[0285] In this embodiment of the disclosure, the design scheme of the second resource offset is shown in Examples 3A-3C below.

[0286] Example 3A, the second resource offset between the reference time and each of the N first times, is a time offset predefined by the protocol.

[0287] Example 3B: The network device may send a second indication information to the terminal device, the second indication information being used to indicate a second resource offset between the reference time and each of the N first times.

[0288] Example 3C: a terminal device determines, according to an index of each of N first time instants in at least one candidate time instant, a second resource offset between a reference time instant and each of the N first time instants.

[0289] For an n-th first time instant among the N first time instants, a second time offset O1 between the reference time instant and the n-th first time instant n satisfies the formula: O1 n =j n ×D; wherein j n represents an index of the n-th first time instant in the at least one candidate time instant, j n is an integer from 0 to (J-1), and J represents a total quantity of the at least one candidate time instant.

[0290] In some embodiments, the at least one candidate time instant is all time instants located after a second time instant among M time instants, that is, J<M.

[0291] In some embodiments, the at least one candidate time instant is M time instants, that is, J=M.

[0292] It is worth noting that in Example 3C, the terminal device needs an index of each of the N first time instants in the at least one candidate time instant.

[0293] In some embodiments, a design solution that enables the terminal device to know the index j n is as shown in the following Example 4A and Example 4B.

[0294] Example 4A: a network device sends third indication information to a terminal device, where the third indication information is used to indicate an index of each of N first time instants in at least one candidate time instant.

[0295] Example 4B: an index of each of N first time instants in at least one candidate time instant is a predefined index of a protocol.

[0296] Based on the foregoing Example 4A and Example 4B, the following describes in detail a design solution of the second resource offset with reference to Example 5A to Example 5C.

[0297] Example 5A: N=1. If M=1, a second resource offset between the reference time instant and the first time instant satisfies: O11=0; if 1<M, a second resource offset between the reference time instant and the first time instant satisfies: O11=j1×D; wherein j1 is any integer from 0 to (J-1).

[0298] Based on Example 5A, in other words, N=1, if M=1, the offset value O11 of 1 CSI-RS Resource in the aperiodic CSI-RS Resource Set satisfies O11=0; if 1<M, the offset value O11 of 1 CSI-RS Resource in the aperiodic CSI-RS Resource Set satisfies: O11=j1×D.

[0299] Example 5B: 1<N<M, the second resource offset between the reference time and the n-th first time among the N first times satisfies: O1 n =j n ×D; wherein j n is any integer from 0 to (J-1).

[0300] It is worth noting that since 1<N, it is necessary to select N j from 0 to (J-1) n for calculating the second resource offset between the reference time and each first time among the N first times.

[0301] Based on Example 5B, in other words, 1<N<M, the aperiodic CSI-RS Resource Set includes at least N CSI-RS Resources, and the offset value O1n of the n-th CSI-RS Resource among the N CSI-RS Resources satisfies: O1 n =j n ×D, wherein j n is any integer from 0 to (J-1).

[0302] Example 5C: 1<N=M, and the third time t2 is located after the second time t1, the second resource offset between the reference time and the n-th first time among the N first times satisfies: O1 n =j n ×D; wherein j n is any integer from 0 to (M-1).

[0303] Based on Example 5C, in other words, 1<N=M, the aperiodic CSI-RS Resource Set includes at least N CSI-RS Resources, and the offset value O1n of the n-th CSI-RS Resource among the N CSI-RS Resources satisfies: O1 n =j n ×D, wherein j n is any integer from 0 to (M-1).

[0304] It is worth noting that since N = M, all integers from 0 to (M-1) are used to calculate the second resource offset between the reference time and each of the N first times.

[0305] In some embodiments, when N = M, the N first moments are the same as the M moments. In this case, it is not necessary to determine the N first moments based on the first time offset and the second time domain offset. Therefore, it is also not necessary to configure the first time offset and the second time domain offset, nor is it necessary to configure the relevant information of the obtained first time offset (e.g., m in Examples 2A and 2B) and the relevant information of the second time domain offset (e.g., j1, j2 in Examples 5A to 5C). n In other words, when N=M, and the first moment in the prediction time obtained by the AI ​​model (i.e., the first moment in the M moments, i.e., the third moment) is after the moment when the reference signal resource set for the DCI triggering aperiodicity is located (i.e., the second moment), the M first moments are the M moments within the prediction window obtained by the AI ​​model.

[0306] In some embodiments, the third moment may be located after the second moment.

[0307] In some embodiments, the third moment may be located before the second moment.

[0308] In some embodiments, when the transmission mode of the channel measurement reference signal is periodic or semi-persistent, the N first moments are N transmission moments, or reference signal transmission moments in N transmission cycles, wherein the time interval between any two adjacent transmission moments in the N transmission moments is the same.

[0309] In some embodiments, the N transmission times are predefined transmission times, and the N transmission periods are predefined transmission periods.

[0310] In some embodiments, the network device may send a fourth indication information to the terminal device, the fourth indication information being used to indicate N transmission times / transmission cycles.

[0311] In some embodiments, the fourth indication information may be Radio Resource Control (RRC) signaling, Medium Access Control Control Element (MAC CE) signaling, or DCI.

[0312] In some embodiments, the N first moments are N transmission moments following the second moment. In this embodiment, the fourth indication information can be RRC signaling or MAC CE signaling.

[0313] When a network device configures one periodic or semi-persistent CSI-RS Resource with a transmission period T for a terminal device, the N first time instants may be located after the second time instant, the N first time instants may be located after the fourth time instant, or the N first time instants may be located before the fifth time instant.

[0314] When the transmission mode of monitoring information is aperiodic transmission (or in other words, the monitoring information reporting is aperiodic reporting), the scenario where the N first time instants are located after the second time instant is described below with reference to Examples 7A to 7C.

[0315] In Example 7A, N=1, and the first time instant is a transmission time instant / transmission period with an index k that is located after the second time instant among M time instants, wherein k is any integer from 1 to M. For example, k is equal to 1 or equal to M.

[0316] In other words, when N=1, the CSI-RS Resource is at the k-th CSI-RS transmission time instant after the second time instant (i.e., DCI triggers CSI reporting).

[0317] In some embodiments, in Example 7A, k may be a predefined index.

[0318] In some embodiments, in Example 7A, the fourth indication information may include the index k.

[0319] In some embodiments, in Example 7A, multiple indexes may be predefined, and the index k is indicated via the fourth indication information, wherein the multiple indexes include the index k.

[0320] In some embodiments, in Example 7A, when the fourth indication information is a MAC CE signaling, multiple indexes are indicated via RRC signaling, and the index k is indicated via the MAC CE signaling, wherein the multiple indexes include the index k.

[0321] In some embodiments, in Example 7A, when the fourth indication information is RRC signaling, multiple indexes are indicated via MAC CE signaling, and the index k is indicated via the RRC signaling, wherein the multiple indexes include the index k.

[0322] FIG. 3e is a schematic position diagram of a first time instant provided by an embodiment of the present disclosure. As shown in FIG. 3e, among the M=3 time instants, the first time instant is located after the second time instant, and one first time instant (where N=1) is the transmission time instant with an index of 1 (k=1).

[0323] In Example 7B, 1<N<M, the N first time instants may be transmission time instants / transmission periods indicated by N indexes among M time instants, and the N indexes are N integers from 1 to M.

[0324] In other words, 1<N<M, the CSI-RS Resource is located at N CSI-RS transmission occasions after the second occasion (i.e., after DCI triggers CSI reporting), and the N CSI-RS transmission occasions include the k={1,2,...,M}-th CSI-RS transmission occasion. For example, when N=2, the N CSI-RS transmission occasions include the k=1-th CSI-RS transmission occasion and the k=2-th CSI-RS transmission occasion.

[0325] In some embodiments, in Example 7B, the N indexes are N pre-defined indexes.

[0326] In some embodiments, in Example 7B, the N indexes may be indexes included in fourth indication information.

[0327] In some embodiments, in Example 7B, a plurality of indexes may be pre-defined, and the N indexes are indicated by the fourth indication information, wherein the plurality of indexes include the N indexes.

[0328] In some embodiments, in Example 7B, when the fourth indication information is a MAC CE signaling, a plurality of indexes are indicated by RRC signaling, and the N indexes are indicated by MAC CE signaling, wherein the plurality of indexes include the N indexes.

[0329] In some embodiments, in Example 7B, when the fourth indication information is RRC signaling, a plurality of indexes are indicated by MAC CE signaling, and the N indexes are indicated by RRC signaling, wherein the plurality of indexes include the N indexes.

[0330] FIG. 3f is a schematic diagram of an example position of a first occasion provided by an embodiment of the present disclosure. As shown in FIG. 3f, the first occasion is among M occasions, the first occasion is located after the second occasion, and 2 first occasions (where N=2) are transmission occasions with indexes 1 and 3.

[0331] Example 7C, 1<N=M, the N first occasions are transmission occasions / transmission periods indicated by M indexes among the M occasions, that is, the N first occasions are the M occasions.

[0332] In other words, 1<N=M, the CSI-RS Resource is located at N CSI-RS transmission occasions after the second occasion (i.e., after DCI triggers CSI reporting), and the N CSI-RS transmission occasions include the k={1,2,...,M}-th CSI-RS transmission occasion. For example, when N=M=3, the N CSI-RS transmission occasions include the k=1-th CSI-RS transmission occasion, the k=2-th CSI-RS transmission occasion, and the k=3-th CSI-RS transmission occasion.

[0333] It is worth noting that in Example 7C, the second time step is M time steps ahead.

[0334] Figure 3g is a positional example of a first moment provided in an embodiment of this disclosure. As shown in Figure 3g, the first moment is located after the second moment in M ​​moments, and the three first moments (N=3) are transmission moments with indices 1, 2 and 3.

[0335] In some embodiments, if the transmission mode of the channel measurement reference signal is periodic or semi-continuous, and the transmission mode of the monitoring information is non-periodic, then the N first moments can be the N transmission moments located after the second moment.

[0336] In some embodiments, the N first moments are the N transmission moments following the fourth moment.

[0337] In this embodiment, the fourth indication information can be RRC signaling, MAC CE signaling, or DCI.

[0338] When the monitoring information is transmitted non-periodicly (or the monitoring information is reported non-periodicly), the following examples 8A to 8C will be used to explain how N first moments are located after the fourth moment.

[0339] Example 8A, N=1, where the first moment is the transmission moment / transmission period that is after the fourth moment in M ​​moments and has an index of k, where k is any integer between 1 and M.

[0340] For example, the first moment could be the first transmission moment after the fourth moment.

[0341] In some embodiments, such as Example 8A, k can be a predefined index.

[0342] In some embodiments, in Example 8A, k can be an index included in the fourth indication information.

[0343] In some embodiments, in Example 8A, multiple indices may be predefined, and index k may be indicated by a fourth indication message, wherein index k is included among the multiple indices.

[0344] In some embodiments, in Example 8A, when the fourth indication information is MAC CE signaling, multiple indices are indicated by RRC signaling, and index k is indicated by MAC CE signaling, wherein index k is included among the multiple indices.

[0345] In some embodiments, in Example 8A, when the fourth indication information is RRC signaling, multiple indices are indicated by MAC CE signaling, and index k is indicated by RRC signaling, wherein index k is included among the multiple indices.

[0346] In some embodiments, in Example 8A, when the fourth indication information is DCI, a plurality of indexes are indicated through RRC signaling, and an index k is indicated through DCI, wherein the plurality of indexes include the index k.

[0347] Figure 3h is a schematic diagram of an example position of a first time instant provided by an embodiment of the present disclosure. As shown in Figure 3h, among the M=3 time instants, the first time instant is located after the fourth time instant, and one first time instant (where N=1) is a transmission moment with index 2 (k=2).

[0348] For Example 8B, 1<N<M, the N first time instants may be transmission moments / transmission periods indicated by N indexes that are located after the fourth time instant among the M time instants, and the N indexes are N integers between 1 and M.

[0349] In some embodiments, in Example 8B, the N indexes are predefined N indexes.

[0350] In some embodiments, in Example 8B, the N indexes may be indexes included in the fourth indication information.

[0351] A plurality of indexes may be predefined, and the N indexes are indicated through the fourth indication information, wherein the plurality of indexes include the N indexes.

[0352] In some embodiments, in Example 8B, when the fourth indication information is MAC CE signaling, a plurality of indexes are indicated through RRC signaling, and the N indexes are indicated through MAC CE signaling, wherein the plurality of indexes include the N indexes.

[0353] In some embodiments, in Example 8B, when the fourth indication information is RRC signaling, a plurality of indexes are indicated through MAC CE signaling, and the N indexes are indicated through RRC signaling, wherein the plurality of indexes include the N indexes.

[0354] In some embodiments, in Example 8B, when the fourth indication information is DCI, a plurality of indexes are indicated through RRC signaling, and the N indexes are indicated through DCI, wherein the plurality of indexes include the N indexes.

[0355] Figure 3i is a schematic diagram of an example position of a first time instant provided by an embodiment of the present disclosure. As shown in Figure 3i, among the M=3 time instants, the first time instants are located after the fourth time instant, and two first time instants (where N=2) are transmission moments with indexes 2 and 3.

[0356] For Example 8C, 1<N=M, the N first time instants are transmission moments / transmission periods indicated by M indexes that are located after the fourth time instant among the M time instants, that is, the N first time instants are the M time instants.

[0357] It is worth noting that in Example 8C, the fourth time step is located before the first time step out of the M time steps.

[0358] Figure 3j is a positional example of the first moment provided in an embodiment of this disclosure. As shown in Figure 3j, the first moment is located after the fourth moment in M ​​moments, and the three first moments (N=3) are transmission moments with indices 1, 2 and 3.

[0359] In some embodiments, if the channel measurement reference signal is transmitted periodically or semi-continuously, the monitoring information is transmitted aperiodically, and the CSI is transmitted aperiodically, then the N first moments can be the N transmission moments located after the fourth moment.

[0360] In some embodiments, the N first moments are the N transmission moments preceding the fifth moment. In this embodiment, the fourth indication information can be RRC signaling, MAC CE signaling, or DCI.

[0361] When the monitoring information is transmitted periodically (or reported periodically), the following explanation, using Examples 9A to 9C, illustrates that the N first moments can be located before the fifth moment. In other words, if the channel measurement reference signal is transmitted periodically or semi-continuously, and the monitoring information is transmitted periodically or semi-continuously, then the N first moments can be the N transmission moments located before the fifth moment.

[0362] Example 9A: When N=1, the first moment is the transmission moment / transmission period with index k that is before the fifth moment in the M moments, where k is any integer between 1 and (MF), and F is the total number of transmission moments / transmission periods that are before the fifth moment in the M moments.

[0363] In some embodiments, k can be indicated via RRC signaling, MAC CE signaling, or DCI.

[0364] In some embodiments, F can be equal to 0, or it can be equal to other values. F equal to 0 can be interpreted as the fifth time point not being among the M time points. F greater than 0 can be interpreted as the fifth time point being among the M time points.

[0365] For example, the first moment could be the first transmission moment preceding the fifth moment.

[0366] FIG. 3k is a schematic position diagram of a first time instant provided by an embodiment of the present disclosure. As shown in FIG. 3k, among the M=3 time instants, the first time instant is located before a fifth time instant, and 1 first time instant (where N=1) is a transmission moment with an index of 2 (that is, k=2).

[0367] In some embodiments, the execution process of Example 9A is similar to that of Example 8A, and details are not described herein again.

[0368] Based on Example 9A, in other words, when N=1, RRC signaling, MAC CE signaling, or DCI may be used to indicate which transmission周期's CSI-RS Resource is used as a channel measurement resource for monitoring an AI model. A terminal device can receive the CSI-RS on the CSI-RS Resource of the transmission周期.

[0369] In Example 9B, 1<N<M, the N first time instants may be transmission instants / transmission periods indicated by N indexes among the M time instants, and the N indexes are N integers between 1 and (M-F).

[0370] In some embodiments, the N indexes may be indicated through RRC signaling, MAC CE signaling, or DCI.

[0371] In some embodiments, the execution process of Example 9B is similar to that of Example 8B, and details are not described herein again.

[0372] FIG. 3l is a schematic position diagram of a first time instant provided by an embodiment of the present disclosure. As shown in FIG. 3l, among the M=3 time instants, the first time instant is located before a fifth time instant, and 2 first time instants (where N=2) are transmission instants with indexes 2 and 3.

[0373] Based on Example 9B, in other words, when 1<N<M, RRC signaling, MAC CE signaling, or DCI may be used to indicate which N transmission周期's CSI-RS Resources are used as channel measurement resources for monitoring an AI model. A terminal device can receive the CSI-RS on the CSI-RS Resources of the N transmission周期s.

[0374] In Example 9C, 1<N=M, the N first time instants are transmission instants / transmission periods indicated by M indexes among the M time instants, that is, the N first time instants are the M time instants.

[0375] It is worth noting that in Example 9C, the fifth time instant is located after the last time instant of the M time instants.

[0376] In some embodiments, the execution process of Example 9C is similar to that of Example 8C, and details are not described herein again.

[0377] Figure 3m is an example diagram of a position at the first time provided by the embodiments of the present disclosure. As shown in Figure 3m, among the M=3 time instants, the first time is before the fifth time, and the 3 first times (where N=3) are the transmission instants with indexes 1, 2, and 3.

[0378] Based on Example 9C, in other words, when 1<N=M, the CSI-RS Resources of which M transmission cycles are used as channel measurement resources for monitoring the AI model can be indicated through RRC signaling, MAC CE signaling, or DCI. A terminal device can receive CSI-RS on the CSI-RS Resources of the M transmission cycles.

[0379] It should be noted that Figure 3k to Figure 3m are described with F=0 as an example.

[0380] It should be noted that Figure 3k to Figure 3m are described by taking arrangement in ascending order of indexes as an example. Optionally, they may also be described by taking arrangement in descending order of indexes as an example.

[0381] In some embodiments, the duration between the fifth time and the transmission time of the first channel measurement reference signal among the N channel measurement reference signals is a preset duration.

[0382] In other words, the duration between the fifth time and the time where the first channel measurement resource among the N channel measurement resources is located is a preset duration.

[0383] In some embodiments, the preset duration T1 satisfies: T1=p×T; wherein p represents a preset value, and T represents the time interval between two adjacent transmission times.

[0384] In some embodiments, a network device can send fifth indication information to a terminal device, where the fifth indication information is used to indicate the preset value p.

[0385] In some embodiments, the fifth indication information may be RRC signaling, MAC CE signaling, or DCI.

[0386] In some embodiments, the N first times include the transmission time of the first channel measurement reference signal, and continuous (N-1) transmission times of channel measurement reference signals located after the first channel measurement reference signal.

[0387] Figure 3n is an example diagram of a position at the first time provided by the embodiments of the present disclosure. As shown in Figure 3n, when M=4 and p=5, the duration between the fifth time and the transmission time of the first channel measurement reference signal among the N channel measurement reference signals is 5T.

[0388] When N=2, the two first moments include the transmission moment of the first channel measurement reference signal and the transmission moment of the first channel measurement reference signal after the first channel measurement reference signal.

[0389] In some embodiments, the N first moments include the transmission moments of the N consecutive channel measurement reference signals prior to the fifth moment.

[0390] In some embodiments, among the transmission times of N consecutive channel measurement reference signals, the transmission time of the channel measurement reference signal most recent to the fifth time can be predefined or indicated by the network device.

[0391] Figure 3o is an example of a position of a first moment provided in an embodiment of this disclosure. As shown in Figure 3o, when M=4 and N=2, the two first moments include the transmission moments of two consecutive channel measurement reference signals prior to the fifth moment. For example, the transmission moment of the channel measurement reference signal most recent to the fifth moment is spaced T apart from the fifth moment.

[0392] Figure 3p is an example of a position of the first time point provided in an embodiment of this disclosure. As shown in Figure 3p, when M=4 and N=2, the two first time points include the transmission times of two consecutive channel measurement reference signals prior to the fifth time point. For example, the transmission time of the channel measurement reference signal most recent to the fifth time point is 2T apart from the fifth time point.

[0393] In step S2105, the terminal device receives N channel measurement reference signals at N first moments and performs measurement processing on the N channel measurement reference signals to obtain the channel measurement information corresponding to each of the N first moments.

[0394] In other words, at N first moments, the terminal device receives N channel measurement reference signals sent by the network device through N channel measurement resources, where one of the N channel measurement resources corresponds to one first moment.

[0395] In other words, at the first moment when N channel measurement resources are available, the terminal device receives N channel measurement reference signals sent by the network device based on the N channel measurement resources.

[0396] In step S2106, the terminal device determines the monitoring information based on the channel measurement information corresponding to each of the N first time moments and the channel prediction information corresponding to each of the N first time moments predicted by the AI ​​model.

[0397] The following examples 10A to 10F illustrate how to determine monitoring information.

[0398] Example 10A: For each first time point, the SGCS corresponding to that first time point is obtained according to Formula 1, and it is determined that the monitoring information includes N SGCS corresponding to each first time point.

[0399] Example 10B: For each first time point, the NMSE corresponding to that first time point is obtained according to Formula 2, and it is determined that the monitoring information includes the NMSEs corresponding to each of the N first times.

[0400] Example 10C: For each first time point, the SGCS corresponding to that first time point is obtained according to Formula 1, and the NMSE corresponding to that first time point is obtained according to Formula 2, thus determining that the monitoring information includes the SGCS and NMSE corresponding to each of the N first times.

[0401] Example 10D: Based on Formula 2, we obtain one SGCS corresponding to N first moments, and determine that the monitoring information includes this SGCS.

[0402] Example 10E: According to Formula 2, we obtain an NMSE corresponding to N first moments, and determine that the monitoring information includes this NMSE.

[0403] Example 10F: Based on Formula 2, we obtain one SGCS and one NMSE corresponding to N first moments, and determine that the monitoring information includes the SGCS and the NMSE.

[0404] Step S2107: The terminal device sends monitoring information to the network device.

[0405] The communication method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2107. For example, step S2104 may be implemented as a standalone embodiment, and steps S2104 to S2107 may be implemented as standalone embodiments, but are not limited thereto.

[0406] In some embodiments, some steps in steps S2101 to S2107 may be swapped in order or performed simultaneously. For example, steps S2103 and S2104 may be swapped in order or performed simultaneously.

[0407] In some embodiments, steps S2101 to S2103 and steps S2105 to S2107 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0408] The following describes the communication method provided in this embodiment of the present disclosure in detail, taking the channel measurement reference signal as CSI-RS and the CSI-RS transmission mode as aperiodic transmission (i.e., the network device configures an aperiodic CSI-RS Resource Set for the terminal device) as an example, in conjunction with Figure 2b.

[0409] Figure 2b is an exemplary flowchart of a communication method provided according to an embodiment of the present disclosure. As shown in Figure 2b, the method includes the following steps:

[0410] In step S2201, the network device sends a DCI to the terminal device. The DCI is used to trigger the terminal device to send a CSI and to trigger an aperiodic CSI-RS Resource Set. The aperiodic CSI-RS Resource Set is used to indicate N CSI-RS.

[0411] In some embodiments, the aperiodic CSI-RS Resource Set includes at least N CSI-RS Resources, wherein the N CSI-RS Resources are used to transmit N CSI-RS.

[0412] In step S2202, the terminal device determines the CSI based on the channel prediction information corresponding to each of the M time points predicted and output by the AI ​​model.

[0413] Step S2203: The terminal device sends a CSI to the network device.

[0414] It is worth noting that the execution methods of steps S2201 to S2203 are the same as those of steps S2101 to S2103, and the execution process of steps S2201 to S2203 will not be described again here.

[0415] In step S2204, the network device sends first indication information to the terminal device. The first indication information is used to indicate the first time offset between the transmission time (i.e., the second time) of the DCI and the reference time.

[0416] In some embodiments, the first time offset O can also be referred to as the time offset / offset value corresponding to the non-periodic CSI-RS Resource Set.

[0417] In step S2205, the network device sends a second indication information to the terminal device. The second indication information is used to indicate the second time offset between the reference time and each of the N first times.

[0418] In other words, the second indication information is used to indicate the second time offset between the reference time and each of the N CSI-RS Resources.

[0419] In step S2206, the terminal device determines the reference time based on the second time and the first time offset.

[0420] In one embodiment, the sum of the second time point and the first time point offset is determined as the reference time point.

[0421] Step S2207: The terminal device determines N first moments from M moments based on the reference moment and the second time offset between the reference moment and each of the N first moments.

[0422] In one embodiment, the sum of the reference time and the second time offset between the reference time and each of the N first times is determined as the N first times.

[0423] For example, when N=2, M=4, and D=2, the second time offset between the reference time and the first first time is 1 time slot (O11=1), and the first first time is the time at which the reference time is offset by 0 time slots (i.e., the first first time is the reference time); the second time offset between the reference time and the second first time is 6 time slots (O12=1), and the second first time is the time at which the reference time is offset by 6 time slots.

[0424] The positional relationship between the reference time and the second time offset is explained below with reference to Figure 3q.

[0425] Figure 3q is an example diagram of the position of the reference time and the second time offset provided in the embodiments of this disclosure. When defining time in terms of time slots, the reference time can be called the reference time slot, and the two first times can be called the two first time slots. As shown in Figure 3q, the second time offset between the reference time slot and the first first time slot is 1 time slot (O11 = 1), and the second time offset between the reference time slot and the second first time slot is 6 time slots (i.e., O12 = 6).

[0426] In other words, step S2207 can be described as follows: The terminal device determines the time of the N CSI-RS Resources based on the reference time and the second time offset between the reference time and each of the N CSI-RS Resources.

[0427] Step S2208: The network device sends N CSI-RS to the terminal device at N first moments.

[0428] In some embodiments, the network device sends N CSI-RS to the terminal device at N first moments, based on N CSI-RS Resources in the aperiodic CSI-RS Resource Set.

[0429] In other words, step S2208 can be described as follows: At the time when N CSI-RS Resources are located, the network device sends N CSI-RS to the terminal device according to the N CSI-RS Resources in the non-periodic CSI-RS Resource Set.

[0430] In step S2209, the terminal device receives N CSI-RS at N first moments and performs measurement processing on the N CSI-RS to obtain the channel measurement information corresponding to each of the N first moments.

[0431] In some embodiments, the terminal device receives N CSI-RS at N first moments, based on N CSI-RS Resources in an aperiodic CSI-RS Resource Set.

[0432] In other words, step S2209 can be described as follows: at the time when the N CSI-RS Resources are located, the terminal device receives the N CSI-RS sent by the network device according to the N CSI-RS Resources.

[0434] Step S2211: The terminal device sends monitoring information to the network device.

[0435] It is worth noting that the execution methods of steps S2208 to S2211 are the same as those of steps S2104 to S2107, and the execution process of steps S2201 to S2203 will not be described again here.

[0436] The communication method involved in the embodiments of this disclosure may include at least one of steps S2201 to S2211.

[0437] In some embodiments, some steps in steps S2201 to S2211 may be performed in a different order or simultaneously. For example, steps S2204 and S2205 may be performed in a different order or simultaneously.

[0438] In some embodiments, some steps in steps S2201 to S2211 are optional. For example, steps S2204 to S2207 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0439] The following describes the communication method provided in this embodiment of the present disclosure in detail, taking the channel measurement resource as CSI-RS Resource, the channel measurement reference signal as CSI-RS, and the CSI-RS transmission mode as aperiodic transmission (i.e., the network device configures an aperiodic CSI-RS Resource Set for the terminal device) as an example, in conjunction with Figure 2c.

[0440] Figure 2c is an exemplary flowchart of a communication method provided according to an embodiment of the present disclosure. As shown in Figure 2c, the method includes the following steps:

[0441] In step S2301, the network device sends a DCI to the terminal device. The DCI is used to trigger the terminal device to send a CSI and to trigger an aperiodic CSI-RS Resource Set. The aperiodic CSI-RS Resource Set is used to indicate N CSI-RS.

[0442] In step S2302, the terminal device determines the CSI based on the channel prediction information corresponding to each of the M time points predicted and output by the AI ​​model.

[0443] Step S2303: The terminal device sends a CSI to the network device.

[0444] In step S2304, the network device sends a first indication information to the terminal device. The first indication information is used to indicate the first time offset between the transmission time (i.e., the second time) of the DCI and the reference time.

[0445] It is worth noting that the execution methods of steps S2301 to S2304 are the same as those of steps S2201 to S2204, and the execution process of steps S2301 to S2304 will not be described again here.

[0446] In step S2305, the network device sends third indication information to the terminal device. The third indication information is used to indicate the index of each of the N first moments in at least one alternative moment.

[0447] In some embodiments, the third indication information includes an index of each of the N first moments in at least one alternative moment.

[0448] In step S2306, the terminal device determines the reference time based on the second time and the first time offset.

[0449] It is worth noting that the execution method of step S2306 is the same as that of step S2206, and the execution process of step S2306 will be described again here.

[0450] In step S2307, the terminal device determines the second time offset between the reference time and each of the N first times based on the index of each of the N first times in at least one alternative time.

[0451] In some embodiments, the index of the nth first time point among N first time points is j in at least one alternative time point. n .

[0452] In some embodiments, the second time offset between the reference time and the nth first time point satisfies the formula: O1 n =j n ×D; where D represents the time interval between two adjacent moments in the M moments.

[0453] In some embodiments, the terminal device can specify the index j of the nth first time moment in at least one alternative time moment. n The product of D and O1 is determined as the second time offset O1 between the reference time and the nth first time. n .

[0454] In step S2308, the terminal device determines N first moments from M moments based on the reference moment and the second time offset between the reference moment and each of the N first moments.

[0455] Step S2309: The network device sends N CSI-RS to the terminal device at N first moments.

[0456] In step S2310, the terminal device receives N CSI-RS at N first moments and performs measurement processing on the N CSI-RS to obtain the channel measurement information corresponding to each of the N first moments.

[0457] In step S2311, the terminal device determines the monitoring information based on the channel measurement information corresponding to each of the N first moments and the channel prediction information corresponding to each of the N first moments predicted by the AI ​​model.

[0458] In step S2312, the terminal device sends monitoring information to the network device.

[0459] It is worth noting that the execution methods of steps S2309 to S2312 are the same as those of steps S2208 to S2211. The execution process of steps S2309 to S2312 will be described again here.

[0460] The communication method involved in the embodiments of this disclosure may include at least one of steps S2309 to S2312. For example, step S2309 may be implemented as a standalone embodiment, step S2304 may be implemented as a standalone embodiment, steps S2303 to S2308 may be implemented as standalone embodiments, and steps S2304 to S2312 may be implemented as standalone embodiments, but are not limited thereto.

[0461] In some embodiments, some steps in steps S2309 to S2312 may be swapped in order or performed simultaneously. For example, steps S2303 and S2304 may be swapped in order or performed simultaneously, and steps S2306 and S2307 may be swapped in order or performed simultaneously.

[0462] In some embodiments, some steps S2309 to S2312 are optional, and one or more of these steps may be omitted or substituted in different embodiments. For example, steps S2301 to S2303 are optional. For example, steps S2305, S2307, and S2308 are optional.

[0463] In the communication methods provided in Figures 2b and 2c, DCI can be used to trigger an aperiodic CSI-RS Resource Set. The aperiodic CSI-RS Resource Set includes at least N CSI-RS Resources. That is, the network device only uses these N CSI-RS Resources to send N CSI-RS, thereby enabling the terminal device to monitor the terminal device's AI model based on the N CSI-RS. The network device will not send redundant CSI-RS, which can save pilot overhead.

[0464] The following describes the communication method provided in this embodiment of the present disclosure in detail, taking the channel measurement resource as one CSI-RS Resource, the channel measurement reference signal as CSI-RS, the CSI-RS transmission mode as periodic transmission (i.e., the network device configures a periodic CSI-RS Resource Set for the terminal device, or in other words, configures a periodic CSI-RS Resource), and the monitoring information transmission mode as non-periodic transmission, in conjunction with Figure 2d, for N transmission times after the second time point in the first time point.

[0470] In step S2404, the network device sends a fourth indication information to the terminal device. The fourth indication information is used to indicate N transmission times after the transmission time of DCI (i.e., the second time).

[0471] In other words, the fourth indication information is used to indicate the N transmission cycles following the second time point.

[0472] In step S2405, the terminal device determines the N transmission times that are after the second time time out of the M time times as the N first time times.

[0473] In other words, the terminal device determines the reference signal transmission time of N transmission cycles after the second time point out of M time points as N first time points.

[0474] In step S2406, the network device periodically sends CSI-RS to the terminal device.

[0475] In other words, at the moment when one CSI-RS Resource is located in each transmission cycle, the network device periodically sends CSI-RS to the terminal device according to one CSI-RS Resource.

[0476] In step S2407, the terminal device receives N CSI-RS at N first moments and performs measurement processing on the N CSI-RS to obtain the channel measurement information corresponding to each of the N first moments.

[0477] In other words, the fourth indication information is used to indicate the N transmission cycles after the second time; step S2405 may be omitted, and the terminal device may receive N CSI-RS through one CSI-RS Resource at the time when the one CSI-RS Resource is located in the N transmission cycles, and perform measurement processing on the N CSI-RS to obtain the channel measurement information corresponding to each of the N first time periods.

[0478] In step S2408, the terminal device determines the monitoring information based on the channel measurement information corresponding to each of the N first moments and the channel prediction information corresponding to each of the N first moments predicted by the AI ​​model.

[0479] Step S2409: The terminal device sends monitoring information to the network device.

[0480] It is worth noting that the execution methods of steps S2407 to S2409 are the same as those of steps S2209 to S2211. The execution process of steps S2405 to S2409 will be described again here.

[0481] The communication method involved in the embodiments of this disclosure may include at least one of steps S2401 to S2409. For example, step S2407 may be implemented as a standalone embodiment. For example, steps S2407 to S2409 may be implemented as standalone embodiments. For example, step S2404 may be implemented as a standalone embodiment. For example, steps S2404 to S2409 may be implemented as standalone embodiments.

[0482] In some embodiments, some steps S2401 to S2409 may be performed in a different order or simultaneously. For example, steps S2401 and S2404 may be performed in a different order or simultaneously.

[0483] In some embodiments, some steps S2401 to S2409 are optional, and one or more of these steps may be omitted or substituted in different embodiments. For example, steps S2401 to S2403 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0484] The following describes the communication method provided in this embodiment of the present disclosure in detail, taking the channel measurement resource as one CSI-RS Resource, the channel measurement reference signal as CSI-RS, the CSI-RS transmission mode as periodic transmission, and the monitoring information transmission mode as aperiodic transmission, in conjunction with Figure 2e, at N transmission times after the fourth time point of the first time point.

[0485] Figure 2e is an exemplary flowchart of a communication method provided according to an embodiment of the present disclosure. As shown in Figure 2e, the method includes the following steps:

[0486] Step S2501: The network device sends a DCI to the terminal device. The DCI is used to trigger the terminal device to send a CSI.

[0490] In step S2504, the network device sends a fourth indication information to the terminal device. The fourth indication information is used to indicate N transmission times after the time when CSI is sent (i.e., the fourth time).

[0491] In other words, the fourth indication information is used to indicate the N transmission cycles following the fourth time point.

[0492] In step S2505, the terminal device determines the N transmission times that are after the fourth time time out of the M time times as the N first time times.

[0493] In other words, the terminal device determines the reference signal transmission time of N transmission cycles after the fourth time point out of M time points as N first time points.

[0494] In step S2506, the network device periodically sends CSI-RS to the terminal device.

[0495] In other words, network devices periodically send CSI-RS to terminal devices according to a CSI-RS Resource in each transmission cycle.

[0496] In step S2507, the terminal device receives N CSI-RS at N first moments and performs measurement processing on the N CSI-RS to obtain the channel measurement information corresponding to each of the N first moments.

[0497] In other words, the fourth indication information is used to indicate the N transmission cycles after the fourth time; step S2505 may be omitted. The terminal device can receive N CSI-RS through one CSI-RS Resource at the time when the one CSI-RS Resource is located in the N transmission cycles, and perform measurement processing on the N CSI-RS to obtain the channel measurement information corresponding to each of the N first time periods.

[0498] In step S2508, the terminal device determines the monitoring information based on the channel measurement information corresponding to each of the N first moments and the channel prediction information corresponding to each of the N first moments predicted by the AI ​​model.

[0499] Step S2509: The terminal device sends monitoring information to the network device.

[0500] It is worth noting that the execution methods of steps S2506 to S2509 are the same as those of steps S2406 to S2409, and the execution process of steps S2506 to S2509 will not be described again here.

[0501] The communication method involved in the embodiments of this disclosure may include at least one of steps S2501 to S2509. For example, step S2507 may be implemented as a standalone embodiment. For example, steps S2507 to S2509 may be implemented as standalone embodiments. For example, step S2504 may be implemented as a standalone embodiment. For example, steps S2504 to S2509 may be implemented as standalone embodiments.

[0502] In some embodiments, some steps S2501 to S2509 may be performed in a different order or simultaneously. For example, steps S2501 and S2504 may be performed in a different order or simultaneously.

[0503] In some embodiments, some steps S2501 to S2509 are optional, and one or more of these steps may be omitted or substituted in different embodiments. For example, steps S2501 to S2503 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0504] The following describes the communication method provided in this embodiment of the present disclosure in detail, taking one CSI-RS Resource as the channel measurement resource, CSI-RS as the channel measurement reference signal, CSI-RS as the transmission mode of periodic transmission, and monitoring information as the transmission mode of periodic transmission, in conjunction with Figure 2f, for a single monitoring information report, during N transmission times before the fifth time point of the first time point.

[0505] Figure 2f is an exemplary flowchart of a communication method provided according to an embodiment of the present disclosure. As shown in Figure 2f, the method includes the following steps:

[0506] Step S2601: The network device sends a DCI to the terminal device. The DCI is used to trigger the terminal device to send a CSI.

[0507] In step S2602, the terminal device determines the CSI based on the channel prediction information corresponding to each of the M time points predicted and output by the AI ​​model.

[0508] Step S2603: The terminal device sends a CSI to the network device.

[0510] In step S2604, the network device sends a fourth indication information to the terminal device. The fourth indication information is used to indicate N transmission times before the time when the monitoring information is sent (i.e., the fifth time).

[0511] In other words, the fourth indication information is used to indicate the N transmission cycles preceding the fifth time point.

[0512] In step S2605, the terminal device determines the N transmission times before the fifth time as the N first times.

[0513] In other words, the terminal device determines the reference signal transmission time of N transmission cycles before the fifth time point out of M time points as N first time points.

[0514] In step S2606, the network device periodically sends CSI-RS to the terminal device.

[0515] In other words, network devices periodically send CSI-RS to terminal devices based on one CSI-RS Resource in each transmission cycle.

[0516] In step S2607, the terminal device receives N CSI-RS at N first moments and performs measurement processing on the N CSI-RS to obtain the channel measurement information corresponding to each of the N first moments.

[0517] In other words, the fourth indication information is used to indicate the N transmission cycles prior to the fifth time. Step S2605 may be omitted. The terminal device receives N CSI-RS through one CSI-RS Resource based on the time of one CSI-RS Resource in the N transmission cycles, and performs measurement processing on the N CSI-RS to obtain the channel measurement information corresponding to each of the N CSI-RS Resources.

[0518] In step S2608, the terminal device determines the monitoring information based on the channel measurement information corresponding to each of the N first moments and the channel prediction information corresponding to each of the N first moments predicted by the AI ​​model.

[0519] In other words, the terminal device determines the monitoring information based on the channel measurement information corresponding to each of the N CSI-RS Resources and the channel prediction information corresponding to each of the N first moments predicted by the AI ​​model. For each CSI-RS Resource, the moment in which the CSI-RS Resource is located in one transmission cycle is one first moment.

[0520] Step S2609: The terminal device sends monitoring information to the network device.

[0521] It is worth noting that the execution methods of steps S2609 to S2609 are the same as those of steps S2406 to S2409. The execution process of steps S2609 to S2609 will not be described again here.

[0522] The communication method involved in the embodiments of this disclosure may include at least one of steps S2601 to S2609. For example, step S2607 may be implemented as a standalone embodiment. For example, steps S2607 to S2609 may be implemented as standalone embodiments. For example, step S2604 may be implemented as a standalone embodiment. For example, steps S2604 to S2609 may be implemented as standalone embodiments.

[0523] In some embodiments, some steps S2601 to S2609 may be performed in a different order or simultaneously. For example, steps S2601 and S2604 may be performed in a different order or simultaneously.

[0524] In some embodiments, some steps S2601 to S2609 are optional, and one or more of these steps may be omitted or substituted in different embodiments. For example, steps S2601 to S2603 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0525] The following describes the communication method provided in this embodiment of the present disclosure in detail, taking the channel measurement resource as one CSI-RS Resource, the channel measurement reference signal as CSI-RS, the CSI-RS transmission mode as periodic transmission, and the monitoring information transmission mode as periodic transmission, in conjunction with Figure 2g, for the reporting of one monitoring information, in the N transmission times before the fifth time of the first time.

[0526] Figure 2g is an exemplary flowchart of a communication method provided according to an embodiment of the present disclosure. As shown in Figure 2g, the method includes the following steps:

[0527] Step S2701: The network device sends a DCI to the terminal device. The DCI is used to trigger the terminal device to send a CSI.

[0528] In step S2702, the terminal device determines the CSI based on the channel prediction information corresponding to each of the M time points predicted and output by the AI ​​model.

[0529] Step S2703: The terminal device sends a CSI to the network device.

[0530] It is worth noting that the execution methods of steps S2701 to S2703 are the same as those of steps S2101 to S2103, and the execution process of steps S2701 to S2703 will not be described again here.

[0531] In step S2704, the network device sends a fifth indication message to the terminal device. The fifth indication message is used to indicate a preset value.

[0532] Step S2705: The terminal device determines the preset duration based on the preset value.

[0533] In one embodiment, the preset value p and the preset duration T1 satisfy: T1 = p × T; T represents the time interval between two adjacent transmission moments when the CSI-RS transmission mode is periodic transmission or semi-persistent transmission, or the duration of the transmission period.

[0534] In one embodiment, T can be a value agreed upon by the protocol, or a value configured by the network device for the terminal device.

[0535] In step S2706, the terminal device determines N transmission times that are before the fifth time and within the preset duration from among the M time times as N first time times.

[0536] In some embodiments, the terminal device determines N first moments as the target moment that is a preset time interval before the fifth moment and the consecutive (N-1) transmission moments after the target moment.

[0537] Figure 3r is an example diagram of the positions of the fifth time point and the first time point provided in the embodiments of this disclosure. As shown in Figure 3r, p = 5, the preset duration T1 = 5T, when N = 3, the time interval between the transmission time of the first CSI-RS among the three CSI-RS and the fifth time point is 5T, the time interval between the transmission time of the second CSI-RS among the three CSI-RS and the fifth time point is 4T, and the time interval between the transmission time of the third CSI-RS among the three CSI-RS and the fifth time point is 3T.

[0538] In other words, step S2706 can also be described as the terminal device determining the reference signal transmission times of N transmission cycles that are before the fifth time and within the preset duration among the M time moments as N first time moments.

[0539] In step S2707, the network device periodically sends CSI-RS to the terminal device.

[0540] In step S2708, the terminal device receives N CSI-RS at N first moments and performs measurement processing on the N CSI-RS to obtain the channel measurement information corresponding to each of the N first moments.

[0541] It is worth noting that the transmission time of the first CSI-RS among the N CSI-RS is the target time in step S2706, and the transmission times of the (N-1) consecutive CSI-RS after the first CSI-RS are the (N-1) consecutive transmission times after the target time in step S2706.

[0542] In step S2709, the terminal device determines the monitoring information based on the channel measurement information corresponding to each of the N first moments and the channel prediction information corresponding to each of the N first moments predicted by the AI ​​model.

[0543] Step S2710: The terminal device sends monitoring information to the network device.

[0544] It is worth noting that the execution methods of steps S2707 to S2710 are the same as those of steps S2406 to S2409. The execution process of steps S2707 to S2710 will be described again here.

[0545] The communication method involved in the embodiments of this disclosure may include at least one of steps S2701 to S2710. For example, step S2704 may be implemented as a standalone embodiment. For example, steps S2707 to S2710 may be implemented as standalone embodiments. For example, steps S2704 to S2710 may be implemented as standalone embodiments.

[0546] In some embodiments, some steps in steps S2701 to S2710 may be performed in a different order or simultaneously. For example, steps S2701 and S2704 may be performed in a different order or simultaneously.

[0547] In some embodiments, some steps S2701 to S2710 are optional, and one or more of these steps may be omitted or substituted in different embodiments. For example, steps S2701 to S2703 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0548] In some embodiments, the duration between the fifth time and the transmission time of the first channel measurement reference signal among the N channel measurement reference signals is a preset duration, which can also be understood as the transmission time of the first channel measurement reference signal being the transmission time of a transmission period that is separated from the fifth time by the preset duration.

[0549] In some embodiments, the N first moments may include the transmission moment of the transmission cycle (i.e., the transmission cycle that is separated from the fifth moment by the preset duration) and the transmission moments of the subsequent (N-1) transmission cycles.

[0550] Figure 3s is an example diagram of the positions of the fifth time point and the first time point provided in the embodiments of this disclosure. As shown in Figure 3r, p=5, the preset duration T1=5T, when N=3, the transmission time of the first CSI-RS among the three CSI-RS is the transmission time of the transmission period 5T apart from the fifth time point, the transmission time of the second CSI-RS among the three CSI-RS is the transmission time of the transmission period 4T apart from the fifth time point, and the transmission time of the third CSI-RS among the three CSI-RS is the transmission time of the transmission period 3T apart from the fifth time point.

[0551] It is worth noting that Figure 3r illustrates the case where the fifth moment is a CSI-RS transmission moment, while Figure 3s illustrates the case where the fifth moment is not a CSI-RS transmission moment.

[0552] In some embodiments of this disclosure, the N transmission times can also be referred to as the reference signal transmission times of N transmission cycles.

[0553] In some embodiments, when N transmission times are the reference signal transmission times for N transmission cycles, the network device may also indicate N transmission cycles to the terminal device.

[0554] It is worth noting that the embodiments disclosed herein are illustrated using the example of transmitting a channel measurement reference signal at a given time.

[0555] In some embodiments, the network device may transmit multiple channel measurement reference signals at a time, and the terminal device may determine a w based on the multiple channel measurement reference signals. r And according to the w r Determine the monitoring information for the AI ​​model.

[0556] In some embodiments, when the number of antenna ports of a network device is greater than 32, the network device can send multiple channel measurement reference signals at one time.

[0557] It is worth noting that when the channel measurement reference signal is CSI-RS, the CSI-RS transmission mode is semi-persistent transmission (i.e., the network device configures a semi-persistent transmission CSI-RS Resource Set for the terminal device, or configures a semi-persistent transmission CSI-RS Resource), and the monitoring information transmission mode is non-periodic transmission, the communication method in this embodiment is similar to that in Figures 2f-2g, and will not be described again here.

[0558] In the embodiments disclosed herein, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations in other embodiments.

[0559] This disclosure also provides embodiments of an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing the steps performed by the first device in any of the above methods. Alternatively, another apparatus is provided that includes units or modules for implementing the steps performed by the second device in any of the above methods.

[0560] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD).

All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0561] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP).
