[0049] The communication method provided by the embodiments of the present application will be described in detail below in combination with the accompanying drawings, some embodiments and application scenarios.

[0050] As shown in FIG. 2, the communication method provided by the embodiments of the present application can include:

[0051] In step 201, the terminal acquires at least one reference signal combination pattern in signal reception, wherein the reference signal combination pattern includes reference signal configuration information of at least one interference signal.

[0052] The signal reception includes at least one of the reception of the reference signal itself and the reception of other signals (such as signals carrying data).

[0053] The reference signal (RS) involved in the reference signal combination pattern can include at least one of a channel state information reference signal (CSI-RS), a tracking reference signal (TRS), a demodulation reference signal (DMRS), a sounding reference signal (SRS), and a synchronization signal block (SSB).

[0054] In some embodiments, the reference signal involved in the reference signal combination pattern is a CSI-RS, and accordingly, the reference signal combination pattern is a CSI-RS combination pattern.

[0055] Generally, since the reference signal combination pattern can give the resource positions of multiple reference signals, the reference signal combination pattern can also be referred to as an RS resource group. For example, when the above reference signal combination pattern is a CSI-RS combination pattern, the resource positions of a CSI-RS group are given, and therefore the CSI-RS combination pattern can also be referred to as a CSI-RS resource group.

[0056] In some embodiments, step 201 can specifically include that, in time domain, the terminal obtains the reference signal combination pattern in a future time window from the network side device at a preset time interval; and / or, in frequency domain, the terminal obtains the reference signal combination pattern from the network side device at a preset frequency domain resource granularity. For example, in time domain, the terminal can obtain the reference signal combination pattern in a future time window from the network side device every 2 slots; in frequency domain, the terminal can obtain the reference signal combination pattern in a future time window from the network side device every 2 resource blocks (RB) or 2 subbands, or the terminal can obtain the reference signal combination pattern in a future time window on the entire currently activated bandwidth part (BWP).

[0057] In some embodiments, step 201 can specifically include that the terminal obtains at least one reference signal combination pattern for signal reception through downlink control information (DCI) to flexibly adjust at least one reference signal combination pattern for signal reception of the terminal in different time periods, thereby performing real-time interference coordination for the terminal. Of course, the terminal can also obtain at least one reference signal combination pattern for signal reception through a radio resource control protocol (RRC).

[0058] The communication method proposed in the embodiments of the present application includes that the terminal obtains reference signal configuration information of at least one interference signal in the reference signal combination pattern for signal reception, that is, the embodiments of the present application consider the influence of interference signals on resources carrying reference signals. Since interference is a key factor restricting the quality of air interface data collection, by controlling the reference signal of the interference signal introduced, the quality of the channel measurement information measured can be improved, that is, the quality of the data collected can be improved.

[0059] Further, by the communication method provided in the embodiments of the present application, 1) the terminal can measure the reference signal configured by the network side device, feed back the interference measurement information and the channel measurement information, and the network side device can perform interference coordination based on the feedback of the terminal to reduce the interference on the terminal; 2) the terminal can select a suitable interference cancellation algorithm or strategy based on the reference signal configured by the network side device, such as AI-based interference cancellation or channel estimation, and each AI model is adapted to one or more reference signal combination patterns, and the network side device indicates the reference signal combination pattern to facilitate the terminal to select a suitable AI model; 3) in the related art, the terminal does not know the source of the interference, that is, it does not know which cell and which RS resource, but after obtaining the at least one reference signal pattern, the terminal can clearly obtain the information, and the obtained information is beneficial for the terminal to design a more advanced interference cancellation algorithm or strategy, such as AI-based interference cancellation, and the terminal can collect data based on the reference signal to train an AI model for a target interference combination.

[0060] Optionally, the communication method provided in the embodiments of the present application can further include that the terminal obtains the effective time information and the effective rule of the reference signal combination pattern from the network side device, so that the terminal measures the channel measurement information within the effective time after the reference signal combination pattern takes effect, instead of blind measurement, to save communication resources, improve communication efficiency, and reduce terminal power consumption. The effective time information of the reference signal combination pattern can include an effective duration, and the effective rule of the reference signal combination pattern can be determined by at least one of the following manners: protocol agreement and network side device indication.

[0061] In step 202, the terminal obtains channel measurement information based on the at least one reference signal combination pattern.

[0062] For example, the terminal measures the corresponding reference signal according to the reference signal ID or the reference signal resource ID corresponding to the interference pattern ID to obtain the channel measurement information.

[0063] Further, the obtained channel measurement information can be used for training or inference of an Artificial Intelligence (AI) model of the terminal. Specifically, the obtained channel measurement information can be used as an input of the AI model of the terminal to train the AI model or use the AI model for inference.

[0064] AI has been widely applied in various fields. Integrating AI into wireless communication networks can significantly improve throughput, reduce latency, and improve user capacity and other technical indicators. There are many basic models / basic algorithms used by AI models, such as neural networks, decision trees, support vector machines, and Bayesian classifiers.

[0066] In the embodiments of the present application, the identifier of the AI model can be an AI model identifier, an AI structure identifier or an AI algorithm identifier, or the identifier of the AI model can be an identifier of a specific data set associated with the AI model, or the identifier of the AI model can be an identifier of a specific scene, environment, channel feature, device related to AI / ML, or the identifier of the AI model can be an identifier of a function, feature, capability or module related to AI / ML. The embodiments of the present application do not make specific limitations.

[0067] It should be noted that the specific training process of the AI model is referred to the related art, which is not the focus of the present application.

[0082] 14) Timestamp information;

[0083] 15) Position information; and

[0084] 16) Quality indication information of the above measurement quantities.

[0085] Optionally, after step 201, the terminal can further obtain first indication information from the network side device, wherein the first indication information is used to indicate at least one of the following:

[0086] whether at least one RS resource in the reference signal combination pattern is used for the terminal to perform channel information measurement (data acquisition);

[0087] at least one RS resource in the reference signal combination pattern comes from a serving cell of the terminal;

[0088] at least one RS resource in the reference signal combination pattern comes from a non-serving cell of the terminal, that is, the reference signal combination pattern includes reference signal configuration information of at least one interference signal.

[0089] In the embodiments of the present application, data acquisition can refer to that the terminal acquires channel measurement information, and the channel measurement information is used for training an AI model, or the channel measurement information is used for inference of the AI model, and the same applies hereinafter.

[0090] Optionally, after step 201, the terminal can further obtain second indication information from the network side device, wherein the second indication information is used to indicate at least one of the following for each RS resource in the reference signal combination pattern:

[0091] a source cell of the RS carried on the RS resource, the source cell including a serving cell of the terminal or a non-serving cell of the terminal;

[0092] a cell ID associated with the RS resource.

[0093] It can be understood that in the case where a reference signal combination pattern contains both RS resources for carrying serving cell RS and RS resources for carrying non-serving cell (neighbor cell or interference cell) RS, the terminal can obtain channel measurement information of a target cell and channel measurement information of interference cells based on the reference signal combination pattern, and the terminal can train an AI model with better generalization performance based on the channel measurement information of the target cell and the channel measurement information of various interference cell combinations.

[0094] Optionally, the reference signal combination pattern is further used to assist in training or inference of an AI model of the terminal. For example, the reference signal combination pattern can be specifically used to assist the terminal in selecting a target AI model that matches the interference environment of the network side; and / or the reference signal combination pattern can be specifically used as an input of the target AI model to improve the performance of the target AI model.

[0095] It should be noted that, in order to ensure the inference effect, for the target AI model, the reference signal combination pattern selected in the channel information measurement (data collection) stage corresponds to the reference signal combination pattern selected in the model inference stage.

[0096] Optionally, each reference signal combination pattern is associated with an interference pattern ID, and one interference pattern ID is associated with at least one reference signal ID or reference signal resource ID corresponding to an interference signal. On this basis, step 202 can specifically include: the terminal selects a target AI model that matches the interference environment of the network side according to the interference pattern ID corresponding to the reference signal combination pattern, to further improve the inference effect of the AI model.

[0097] Further, as shown in FIG. 3, the communication method proposed by the embodiments of the present application can further include:

[0098] In step 203, the terminal inputs the channel measurement information into a target AI model for inference to obtain N inference results, wherein one inference result corresponds to one reference signal combination pattern, and N is a positive integer.

[0099] It can be understood that, since one reference signal combination pattern is associated with one interference pattern ID, N reference signal combination patterns are associated with N interference pattern IDs, and N groups of channel measurement information are obtained by measurement, then the N groups of channel measurement information are respectively taken as inputs of the target AI model, and N inference results can be correspondingly obtained.

[0100] In step 204, the terminal reports first information to the network side device.

[0101] The first information includes at least one of the following:

[0102] The N inference results and the reference signal combination patterns respectively associated with the N inference results;

[0103] Performance indication information of the target AI model under different reference signal combination patterns;

[0104] The N inference results and the cell ID combinations respectively associated with the N inference results;

[0105] Performance indication information of the target AI model under different cell ID combinations.

[0106] It can be understood that, by reporting the above first information to the network side device, the network side device can understand the influence of different reference signal combination patterns (i.e., different interference levels) on the target AI model of the terminal, so as to coordinate the interference formed by the network side to the terminal.

[0107] Optionally, the communication method proposed in the embodiment of the present application can further include:

[0108] The terminal reports second information to the network side device, wherein the second information is used to indicate at least one of the following information:

[0109] The cell ID associated with the reference signal combination pattern that can be processed by the terminal;

[0110] The reference signal combination pattern ID that can be processed by the terminal;

[0111] The reference signal ID or reference signal resource ID that can be processed by the terminal.

[0112] It can be understood that, by reporting the above second information to the network side device, the network side device can further understand the actual interference that can be processed by the terminal, so as to better coordinate the interference formed by the network side to the terminal.

[0113] Optionally, in addition to the reference signal configuration information of at least one interference signal, the reference signal combination pattern also includes reference signal configuration information of at least one serving cell, so that the terminal can measure the channel measurement information of the serving cell under different interference.

[0114] In some embodiments, in the reference signal combination pattern, the reference signal configuration information of the reference signal of the serving cell or the reference signal of the interference signal can include but is not limited to at least one of the following:

[0120] The terminal receives third information from the network side device, wherein the third information is used to instruct the terminal to switch to the first BWP in the plurality of pre-configured candidate BWPs, and the information carried by the first BWP can be used for training or inference of the AI model. Wherein, the third information can be indicated by the network side device through RRC or DCI.

[0121] For example, as shown in FIG. 4, the network side device pre-configures a plurality of candidate BWPs: BWP1, BWP2, BWP3 and BWP4, and instructs the terminal to switch to BWP3 in the plurality of candidate BWPs through RRC or DCI, and adds indication information in the RRC or DCI, indicating that the reference signal carried by BWP3 can be used for data transmission and measurement of channel measurement information by the terminal.

[0122] Further, regarding the switching of the BWP:

[0126] c. The terminal determines whether the currently activated BWP is the same as the first BWP, and if not, switches to the first BWP, and after a set timer (Timer) expires, falls back to a default BWP. At the same time, the first BWP is no longer used by the terminal for channel measurement information measurement, and whether the default BWP is used for channel measurement information measurement depends on the configuration of the network side device on the default BWP.

[0127] Alternatively, the communication method provided in the embodiments of the present application can further include:

[0130] determines that the first BWP continues to be used for channel information measurement according to a protocol agreement until receiving indication information for deactivating the first BWP;

[0131] determines that the first BWP is no longer used for channel information measurement.

[0132] 2) If the BWP associated with the reference signal resource is the first BWP in the plurality of candidate BWPs pre-configured by the network side device, the communication method provided in the embodiments of the present application can further include:

[0134] The terminal receives third information from the network side device, wherein the third information is used to activate the first BWP in the plurality of candidate BWPs, and indicates that the information carried by the first BWP can be used for training or inference of an AI model.

[0135] The third information can be indicated by the network side device through RRC or DCI.

[0136] For example, as shown in FIG. 5, the network side device preconfigures multiple candidate BWPs: BWP1, BWP2, BWP3 and BWP4, and after the network side device indicates the terminal to activate the third BWP (BWP3) through RRC or DCI, the network side device indicates the terminal to activate the first BWP (BWP2) through another indication, wherein the third BWP is used for downlink data transmission, and the first BWP is used for the terminal to perform measurement of channel measurement information.

[0137] For the preconfiguration of multiple candidate BWPs, please refer to related technologies, and details are not described herein.

[0138] Further, regarding the switching of the BWP:

[0139] The communication method provided in the embodiment of the present application can further include at least one of the following:

[0140] a. The terminal determines whether the currently activated BWP is the same as the third BWP, and if so, the terminal does not perform switching of the BWP;

[0141] b. The terminal determines whether the currently activated BWP is the same as the third BWP, and if not, switches to the first BWP;

[0142] c. The terminal determines whether the currently activated BWP is the same as the third BWP, and if not, switches to the third BWP, and after a set timer (Timer) expires, falls back to a default BWP.

[0143] And / or, the communication method provided in the embodiment of the present application can further include at least one of the following:

[0144] a. The terminal determines whether to activate the first BWP according to the explicit indication of the network side device;

[0145] b. The terminal activates a timer while activating the first BWP according to the indication of the network side device, and deactivates the first BWP after a set timer (Timer) expires. That is, for the first BWP, an activation / deactivation mechanism is adopted.

[0146] As can be seen, in this embodiment, the terminal can activate two BWPs at the same time, one for normal data transmission and the other for measurement of channel measurement information (or for measurement of channel measurement information and normal data transmission), and if no measurement of channel measurement information is performed, the first BWP is deactivated, at which time the terminal can run two or more FFT modules at the same time.

[0147] In the embodiments of the present application, the duration of the timer can be configured by the network side device, for example, the duration of the timer can be configured as 10s, 10ms, etc.

[0148] 3) If the BWP associated with the reference signal resource is a second BWP additionally configured by the network side device on the basis of the plurality of candidate BWPs pre-configured, the communication method proposed in the embodiments of the present application further includes:

[0149] The terminal receives sixth information sent by the network side device, wherein the sixth information is used to configure the second BWP and indicates that the information carried by the second BWP can be used for training or inference of an AI model.

[0150] For example, as shown in FIG. 6, the network side device pre-configures a plurality of candidate BWPs: BWP1, BWP2, BWP3 and BWP4, and on the basis of this, the network side device additionally configures a BWP5 for measurement of channel measurement information. In FIG. 6, the currently activated BWP3 can be used for transmission of downlink data, and the additionally configured and activated BWP5 can be used for measurement of channel measurement information.

[0151] Further, regarding switching of the BWP:

[0152] The communication method proposed in the embodiments of the present application further includes at least one of the following:

[0153] a. The terminal determines whether the currently activated BWP is the same as the BWP3, and if so, the terminal does not perform switching of the BWP;

[0154] b. The terminal determines whether the currently activated BWP is the same as the BWP3, and if not, switches to the BWP3;

[0155] c. The terminal determines whether the currently activated BWP is the same as the BWP3, and if not, switches to the BWP3 and reverts to a default BWP after expiration of a set timer (Timer).

[0156] And / or, the communication method proposed in the embodiments of the present application further includes at least one of the following:

[0157] a. The terminal determines whether to activate the second BWP according to an explicit indication of the network side device;

[0158] b. The terminal activates a timer while activating the second BWP according to the indication of the network side device, and deactivates the second BWP after expiration of the set timer (Timer). That is, for the second BWP, an activation / deactivation mechanism is adopted.

[0159] It can be seen that in this embodiment, the terminal can activate two BWPs at the same time, one for normal data transmission and the other for measurement of channel measurement information (or for measurement of channel measurement information and normal data transmission), and if no measurement of channel measurement information is performed, the second BWP is deactivated, at which time the terminal can simultaneously run two or more FFT modules.

[0160] Optionally, the configuration of the BWP can be initiated by the terminal, and the terminal can also request the network side to configure the BWP for measurement of channel measurement information. Optionally, the terminal can also request the network side device to configure the BWP parameters.

[0161] Optionally, the first BWP, the second BWP, the reference signal on the first BWP, and the reference signal on the second BWP can satisfy certain conditions, such as the adjacent cell interference being less than a first threshold, or the network side considering that the requirements of the terminal for measurement of channel measurement information can be met.

[0162] Optionally, the first BWP or the second BWP can be used not only for the terminal to measure channel measurement information, but also for normal downlink data transmission, such as various PDCCH configurations and PDSCH configurations, and the like; of course, the first BWP or the second BWP can also be used only for reference signal configuration, and no signal is transmitted on the time-frequency resources other than the reference signal resources (such as the power of the reference signal transmission can be raised); or the first BWP or the second BWP can be used entirely for transmitting reference signals.

[0163] It can be understood that after the first BWP or the second BWP is configured and activated, the terminal can measure channel measurement information based on the reference signals on the first BWP or the second BWP.

[0164] The configuration and switching of the BWP related to the embodiments of the present application are described above.

[0165] Optionally, the communication method proposed in the embodiments of the present application can also include:

[0166] The terminal receives the first parameter configured by the network side device, wherein the first parameter is used to indicate the frequency domain density and the period of the BWP (such as the first BWP or the second BWP) associated with the reference signal resource in the reference signal combination pattern, so as to facilitate the terminal to accurately measure the reference signals on these reference signal resources.

[0167] The first parameter can include but is not limited to at least one of the following:

[0168] The absolute frequency domain density and the absolute period of the BWP;

[0169] a relative frequency domain density and a relative periodicity of the BWP;

[0170] a resource mapping rule of the reference signal on the BWP.

[0171] For example, assuming that the reference signal involved in the reference signal combination pattern is CSI-RS, a higher density can be configured in the frequency domain of the first BWP or the second BWP, and a smaller periodicity can be configured in the time domain of the first BWP or the second BWP, and the specific configuration is as follows the first parameter:

[0172] a. Absolute frequency domain density and absolute periodicity, such as a frequency domain density of 6 and an absolute periodicity of 1 ms;

[0173] b. Relative frequency domain density and relative periodicity, relative to the frequency domain density and periodicity of the currently activated BWP or the third BWP, such as a density of M times that of the currently activated BWP or the third BWP, and a periodicity of 1 / N of the currently activated BWP or the third BWP;

[0174] c. The resource mapping rule can follow the existing protocol, or by default, the resource mapping rule is the same as that of the CSI-RS in the currently activated BWP or the third BWP.

[0175] Further, in an AI-related use case, an AI model can be related to the beam antenna configuration of one or more network side devices, and during model inference, the terminal can select a suitable AI model for inference by obtaining the beam antenna configuration of the network side device, thereby improving the accuracy of model inference. Therefore, the communication method proposed in the embodiments of the present application can further include:

[0176] The terminal obtains the beam antenna configuration information of the network side device associated with the reference signal resource in the reference signal combination pattern.

[0177] Specifically, the terminal obtains the beam antenna configuration information of the network side device associated with the reference signal resource, including: the terminal obtains a beam antenna ID associated with the reference signal resource, wherein the beam antenna ID is used to indicate the beam antenna configuration information of the network side device associated with the reference signal resource.

[0178] The beam antenna configuration information is configured by the network side device in at least one of the following ways:

[0179] The network side device configures a set of beam antenna IDs for each type of reference signal resource, and one beam antenna ID is associated with one beam antenna configuration information;

[0180] The network-side device configures a common set of beam antenna IDs for the reference signal resources associated with the same cell, and one beam antenna ID is associated with one beam antenna configuration information.

[0181] The beam antenna configuration information can include, but is not limited to, at least one of the following:

[0182] The number of antenna elements, including the number of antenna elements in the horizontal direction and / or the number of antenna elements in the vertical direction;

[0183] The antenna spacing, including the antenna spacing in the horizontal direction and / or the antenna spacing in the vertical direction;

[0184] The mechanical downtilt angle;

[0185] The antenna height;

[0186] The antenna panel orientation;

[0187] The beam pointing;

[0188] The half-power beam width;

[0189] The beamforming codebook, including the beamforming codebook in the horizontal direction and / or the beamforming codebook in the vertical direction;

[0190] The electronic downtilt angle;

[0191] The mapping relationship between the physical beam and the RS identifier.

[0192] Further, in order to reduce signaling, save communication resources, and improve communication efficiency, the communication method proposed in the embodiments of the present application can further include:

[0193] The terminal obtains fourth information from the network-side device, wherein the fourth information is used to indicate that the first reference signal and the second reference signal carried by the reference signal resources have a quasi co-location (QCL) relationship, and the first reference signal and the second reference signal having the QCL relationship have the same or similar beam antenna configuration information.

[0194] In the embodiments of the present application, the second reference signal can be a reference signal carried by the reference signal resources in the reference signal combination pattern, or can be another reference signal.

[0195] In the embodiments of the present application, the QCL relationship type of the first reference signal and the second reference signal can be any one of QCL-A, QCL-B, QCL-C, and QCL-E, and the embodiments of the present application do not limit this.

[0196] Optionally, in the embodiment of the application, the QCL relationship type of the first reference signal and the second reference signal is QCL-E. That is, when configuring the first reference signal, the network side device can configure a new QCL-E relationship to indicate that the first reference signal and the second reference have the same beam antenna configuration. For example, the first reference signal, SSB, has an associated ID = 1, and the network side device indicates that the CSI-RS has a QCL-E relationship with the SSB. It is considered that the CSI-RS has a QCL-E relationship with the SSB with an associated ID = 1.

[0197] In the embodiment of the application, the reference signal configuration information of at least one interference signal is included in the reference signal combination pattern when the terminal acquires the signal. That is, the embodiment of the application considers the influence of the interference signal on the resource carrying the reference signal. Since the interference is a key factor restricting the quality of the air interface data acquisition, by controlling the reference signal of the interference signal, the quality of the channel measurement information obtained by measurement can be improved, that is, the quality of the acquired data is improved.

[0198] Two specific embodiments of using the communication method proposed in the embodiment of the application to acquire high-quality data are introduced below.

[0199] Embodiment one: CSI compression

[0200] When training the AI model, based on the CSI-RS combination pattern for channel measurement information and the BWP (such as the first BWP or the second BWP described above), a high-quality PMI data set can be obtained, and the terminal, the network side device, or the third party server can train the AI model based on the high-quality PMI data set.

[0201] As shown in FIG. 7, the input of the AI module is a low-precision PMI, and the corresponding label is a high-precision PMI. The low-precision PMI is caused by the interference of the adjacent area and / or the low time-frequency domain density of the CSI-RS. The high-precision PMI is obtained in the first BWP or the second BWP described above, and the time-frequency domain density of the corresponding CSI-RS is higher, so the precision of the measured PMI is higher.

[0202] Embodiment two: channel estimation

[0203] When training the AI model, based on the CSI-RS combination pattern for channel measurement information and the BWP (such as the first BWP or the second BWP described above), a high-quality channel state information data set can be obtained, and the terminal, the network side device, or the third party server can train the AI model based on the high-quality channel state information data set.

[0204] As shown in FIG. 8, the input of the AI module is low-precision CSI, and the corresponding label is high-precision CSI. Among them, the low-precision CSI is caused by the interference of the adjacent cell, and / or the low-precision CSI is the non-interpolated CSI (i.e. the CSI of the pilot position); the high-precision CSI is obtained in the first BWP or the second BWP, and the time-frequency domain density of the corresponding CSI-RS is higher, so the measured CSI is more accurate.

[0205] Among them, for the non-interpolated CSI, for example, in a time slot, it can be the CSI located at the 2nd and 11th OFDM symbols; for another example, in a PRB, it can be the CSI located at the 1st, 3rd, 5th, 7th, 9th, and 11th subcarriers; for another example, assuming there are 8 transmit antenna ports, it can be the CSI located at the 1st, 3rd, 5th, and 7th ports.

[0206] At this time, the AI model can at least play one of the following roles: 1) reduce the influence of cell interference on channel estimation accuracy; 2) interpolate to obtain the time domain, frequency domain, and spatial domain channels on the REs without inserting pilots.

[0207] Embodiment three: interference prediction

[0208] Examples of interference prediction can include, but are not limited to, at least one of the following:

[0210] Predicting the interference signal power of the next M time slots based on the historical interference signal power of the next N time slots;

[0211] Predicting the interference PMI of the next M time slots based on the historical interference measurement reference signal PMI of the next N time slots;

[0212] Predicting the PMI of the next M time slots based on the historical target PMI of the next N time slots, and the like.

[0213] As shown in FIG. 9, another embodiment of the application proposes a communication method, which can include:

[0214] Step 901, the network side device sends at least one reference signal combination pattern in signal reception to the terminal, wherein the reference signal combination pattern includes reference signal configuration information of at least one interference signal, and the reference signal combination pattern is used by the terminal to obtain channel measurement information.

[0215] The reference signals involved in the reference signal combination pattern can include, but are not limited to, at least one of a channel state information-reference signal (CSI-RS), a tracking reference signal (TRS), a demodulation reference signal (DMRS), a sounding reference signal (SRS), and a synchronization signal / PBCH block (SSB).

[0216] In some embodiments, the reference signals involved in the reference signal combination pattern are CSI-RSs, and accordingly, the reference signal combination pattern is a CSI-RS combination pattern.

[0217] Generally, since the reference signal combination pattern can give the resource positions of multiple reference signals, the reference signal combination pattern can also be referred to as an RS resource group. For example, when the reference signal combination pattern is a CSI-RS combination pattern, the resource positions of a CSI-RS group are given, and accordingly, the CSI-RS combination pattern can also be referred to as a CSI-RS resource group.

[0218] In some embodiments, step 901 can specifically include that, in the time domain, the network-side device sends the reference signal combination pattern in a future time window to the terminal at a preset time interval; and / or, in the frequency domain, the network-side device sends the reference signal combination pattern to the terminal at a preset frequency domain resource granularity. For example, in the time domain, the network-side device can send the reference signal combination pattern in a future time window to the terminal every 2 slots; in the frequency domain, the network-side device can send the reference signal combination pattern in a future time window to the terminal every 2 resource blocks (RBs) or 2 subbands, or the network-side device can send the reference signal combination pattern in a future time window to the terminal on the entire partial bandwidth (BWP) currently activated by the terminal.

[0219] In some embodiments, step 901 can specifically include that the network-side device sends at least one reference signal combination pattern in signal reception to the terminal through downlink control information (DCI).

[0220] The communication method provided in the embodiment of the application includes reference signal configuration information of at least one interference signal in a reference signal combination pattern sent to a terminal, that is, the embodiment of the application considers the influence of interference signals on resources carrying reference signals. Since interference is a key factor restricting the quality of air interface data collection, the quality of channel measurement information measured by controlling the reference signal introducing interference signals can be improved, that is, the quality of data collected by the terminal can be improved.

[0221] In addition, through the communication method provided in the embodiment of the application, 1) the terminal can measure the reference signal configured by the network side device, feed back interference measurement information and channel measurement information, and the network side device can perform interference coordination based on the feedback of the terminal to reduce interference on the terminal; 2) the terminal can select a suitable interference cancellation algorithm or strategy based on the reference signal configured by the network side device, such as AI-based interference cancellation or channel estimation, each AI model is adapted to one or more reference signal combination patterns, and the network side device instructs the reference signal combination pattern to facilitate the terminal to select a suitable AI model; 3) in the related art, the terminal does not know the source of interference, that is, it does not know which cell and which RS resource, but after obtaining the at least one reference signal pattern, the terminal can clearly obtain the information, and obtaining the information is beneficial to the terminal to design a more advanced interference cancellation algorithm or strategy, such as AI-based interference cancellation, and the terminal can train an AI model for a target interference combination based on the data collected from the reference signal.

[0222] Optionally, the communication method provided in the embodiment of the application can further include that the network side device sends effective time information and validity rules of the reference signal combination pattern to the terminal, so that the terminal measures channel measurement information within the effective time after the reference signal combination pattern takes effect, instead of blind measurement, to save communication resources, improve communication efficiency, and reduce terminal power consumption.

[0223] Further, the reference signal combination pattern sent in step 901 can be used by the terminal to obtain channel measurement information, and the obtained channel measurement information can be used for training or inference of an artificial intelligence (AI) model of the terminal. Specifically, the obtained channel measurement information can be used as an input of the AI model of the terminal to train the AI model or use the AI model for inference.

[0224] In the embodiment of the application, the above-mentioned channel measurement information can include but is not limited to at least one of the following:

[0225] 1) Reference Signal Receiving Power (RSRP);

[0226] 2) Signal Interference Noise Ratio (SINR);

[0227] 3) CSI, including at least one of CSI-RS resource indicator (CRI), Rank indication (RI), Precoding Matrix Indicator (PMI), Channel Quality Indicator (CQI) and Layer Indicator (LI);

[0228] 4) Received signal quality;

[0229] 5) Precoding Matrix Indicator (PMI);

[0230] 6) Power Delay Profile (PDP);

[0231] 7) Delay Profile (DP);

[0232] 8) Reference signal ID;

[0233] 9) Reference signal resource type;

[0234] 10) Reference signal resource set ID;

[0235] 11) Cell ID;

[0236] 12) TRP ID;

[0237] 13) Frequency domain resource, including frequency and bandwidth, such as 2.6G-2.7GHz, 100M;

[0238] 14) Timestamp information;

[0239] 15) Position information; and

[0240] 16) Quality indication information of the above measurement quantities.

[0241] Optionally, after step 901, the network-side device can further send first indication information to the terminal, wherein the first indication information is used to indicate at least one of the following:

[0242] whether at least one RS resource in the reference signal combination pattern is used for the terminal to perform channel information measurement;

[0243] whether at least one RS resource in the reference signal combination pattern comes from a serving cell of the terminal;

[0244] whether at least one RS resource in the reference signal combination pattern comes from a non-serving cell of the terminal, that is, the reference signal combination pattern includes reference signal configuration information of at least one interference signal.

[0245] Optionally, after step 901, the network-side device can further send second indication information to the terminal, wherein the second indication information is used to indicate at least one of the following for each RS resource in the reference signal combination pattern:

[0246] a source cell of RS carried on the RS resource, wherein the source cell includes a serving cell of the terminal or a non-serving cell of the terminal;

[0247] a cell ID associated with the RS resource.

[0248] It can be understood that, in a case where a reference signal combination pattern contains both RS resources for carrying RS of a serving cell and RS resources for carrying RS of a non-serving cell (a neighbor cell or an interference cell), the terminal can obtain channel measurement information of a target cell and channel measurement information of interference cells based on the reference signal combination pattern, and the terminal can train an AI model with better generalization performance based on the channel measurement information of the target cell and the channel measurement information of various interference cell combinations.

[0249] Optionally, the reference signal combination pattern is further used to assist training or inference of the AI model of the terminal. For example, the reference signal combination pattern can be specifically used to assist the terminal in selecting a target AI model that matches an interference environment of the network side; and / or the reference signal combination pattern can be specifically used as an input of the target AI model to improve performance of the target AI model.

[0250] It should be noted that, to ensure inference effect, for the target AI model, the reference signal combination pattern selected in the channel information measurement (data collection) stage corresponds to the reference signal combination pattern selected in the model inference stage.

[0251] Optionally, each of the reference signal combination patterns is associated with an interference pattern ID, and one interference pattern ID is associated with at least one reference signal ID or reference signal resource ID corresponding to an interference signal. On this basis, the corresponding terminal selects a target AI model matched with the interference environment of the network side according to the interference pattern ID corresponding to the reference signal combination pattern, so as to further improve the inference effect of the AI model.

[0252] Further, the communication method proposed in the embodiment of the application can further include:

[0253] The network side device receives the first information reported by the terminal, wherein the first information is reported by the terminal after obtaining channel measurement information according to the reference signal ID or reference signal resource ID corresponding to the interference pattern ID, inputting the channel measurement information into the target AI model for inference, and obtaining N inference results, one inference result corresponding to one reference signal combination pattern, and N being a positive integer.

[0254] The first information includes at least one of the following:

[0255] The N inference results and the reference signal combination patterns respectively associated with the N inference results;

[0256] Performance indication information of the target AI model under different reference signal combination patterns;

[0257] The N inference results and the cell ID combinations respectively associated with the N inference results;

[0258] Performance indication information of the target AI model under different cell ID combinations.

[0259] It can be understood that the terminal reports the above-mentioned first information to the network side device, so that the network side device can understand the influence of different reference signal combination patterns (i.e. different interference levels) on the target AI model of the terminal, thereby coordinating the interference formed by the network side to the terminal.

[0260] Further, the communication method proposed in the embodiment of the application can further include: the network side device receives the second information reported by the terminal, wherein the second information is used to indicate at least one of the following information:

[0261] The cell ID associated with the reference signal combination pattern that can be processed by the terminal;

[0262] The reference signal combination pattern ID that can be processed by the terminal;

[0263] The reference signal ID or reference signal resource ID that can be processed by the terminal.

[0264] It can be understood that the terminal reports the second information to the network side device, so that the network side device can further understand the actual interference processing capability of the terminal, thereby better coordinating the interference formed by the network side to the terminal.

[0265] Optionally, in addition to the reference signal configuration information of the at least one interference signal, the reference signal combination pattern further includes reference signal configuration information of at least one serving cell, so as to facilitate the terminal to perform channel measurement information measurement on the serving cell under different interference.

[0266] In some embodiments, in the reference signal combination pattern, the reference signal configuration information of the reference signal of the serving cell or the reference signal of the interference signal can include but is not limited to at least one of the following:

[0267] a reference signal ID or a reference signal resource ID;

[0268] a cell ID associated with a reference signal resource;

[0270] In some embodiments, the BWP associated with the reference signal resource can be a first BWP in a plurality of candidate BWPs pre-configured by the network side device, that is, a dedicated BWP is specified in the plurality of candidate BWPs for the terminal to perform channel measurement information measurement; in other embodiments, the BWP can be a second BWP additionally configured by the network side device on the basis of the plurality of candidate BWPs, that is, a dedicated second BWP is additionally configured for the terminal to perform channel measurement information measurement.

[0271] 1) If the BWP associated with the reference signal resource is the first BWP in the plurality of candidate BWPs pre-configured by the network side device, the communication method proposed in the embodiment of the application can further include:

[0272] The network side device sends third information to the terminal, wherein the third information is used to instruct the terminal to switch to the first BWP in the plurality of candidate BWPs pre-configured, and the information carried by the first BWP can be used for AI model training or inference. Wherein the third information can be indicated by the network side device through RRC or DCI.

[0273] For example, as shown in FIG. 4, the network side device preconfigures multiple candidate BWPs: BWP1, BWP2, BWP3 and BWP4, and indicates the terminal to switch to BWP3 in the multiple candidate BWPs through RRC or DCI, and adds indication information in the RRC or DCI, indicating that the reference signal carried by BWP3 can be used for data transmission and channel measurement information measurement of the terminal.

[0274] 2) If the BWP associated with the reference signal resource is the first BWP in the multiple candidate BWPs preconfigured by the network side device, the communication method proposed in the embodiment of the application can further include:

[0275] The network side device sends fifth information to the terminal, where the fifth information is used to activate the third BWP in the multiple BWPs.

[0276] The network side device sends third information to the terminal, where the third information is used to activate the first BWP in the multiple candidate BWPs, and indicates that the information carried by the first BWP can be used for AI model training or inference.

[0277] The third information can be indicated by the network side device through RRC or DCI.

[0278] For example, as shown in FIG. 5, the network side device preconfigures multiple candidate BWPs: BWP1, BWP2, BWP3 and BWP4, and after indicating the terminal to activate the third BWP-BWP3 through RRC or DCI, the network side device indicates the terminal to activate the first BWP-BWP2 through another indication, where the third BWP is used for downlink data transmission, and the first BWP is used for terminal channel measurement information measurement.

[0279] 3) If the BWP associated with the reference signal resource is the second BWP additionally configured by the network side device on the basis of the multiple candidate BWPs preconfigured, the communication method proposed in the embodiment of the application can further include:

[0280] The network side device sends sixth information to the terminal, where the sixth information is used to configure the second BWP, and indicates that the information carried by the second BWP can be used for AI model training or inference.

[0281] For example, as shown in FIG. 6, the network side device preconfigures multiple candidate BWPs: BWP1, BWP2, BWP3 and BWP4, and on this basis, the network side device additionally configures a BWP5 for channel measurement information measurement. In FIG. 6, the currently activated BWP3 can be used for downlink data transmission, and the additionally configured and activated BWP5 can be used for channel measurement information measurement.

[0282] Optionally, the first BWP, the second BWP, the reference signal on the first BWP and the reference signal on the second BWP can meet certain conditions, for example, the adjacent cell interference is less than a first threshold, or the network side considers that the requirements of the terminal for channel measurement information measurement can be met.

[0283] Optionally, the first BWP or the second BWP can be used for normal downlink data transmission in addition to being used for terminal channel measurement information measurement, such as various PDCCH configurations and PDSCH configurations, and the like; of course, the first BWP or the second BWP can also be used only for reference signal configuration, and no signal is transmitted on the time-frequency resource outside the reference signal resource (such as the power of the reference signal transmission can be raised); or the first BWP or the second BWP can be used for transmitting reference signals.

[0284] It can be understood that after the first BWP or the second BWP is configured and activated, the terminal can perform channel measurement information measurement based on the reference signal on the first BWP or the second BWP.

[0285] Optionally, the communication method proposed in the embodiment of the application can further include:

[0286] The network side device configures a first parameter to the terminal, wherein the first parameter is used to indicate the frequency domain density and the period of the BWP (such as the first BWP or the second BWP) associated with the reference signal resource in the reference signal combination pattern, so as to facilitate the terminal to accurately measure the reference signal on the reference signal resource.

[0287] The first parameter can include but is not limited to at least one of the following:

[0289] The relative frequency domain density and the relative period of the BWP;

[0290] The resource mapping rule of the reference signal on the BWP.

[0291] For example, assuming that the reference signal involved in the reference signal combination pattern is CSI-RS, the frequency domain of the first BWP or the second BWP can be configured with higher density, and the time domain of the first BWP or the second BWP can be configured with smaller period, and the first parameter is configured as follows:

[0292] a. The absolute frequency domain density and the absolute period, such as a frequency domain density of 6 and an absolute period of 1ms;

[0293] b. relative frequency domain density and relative period, the frequency domain density and period relative to the currently activated BWP or the third BWP described above, such as the density being M times that of the currently activated BWP or the third BWP described above, and the period being 1 / N of that of the currently activated BWP or the third BWP described above;

[0294] c. the resource mapping rule can follow the existing protocol, or by default, the resource mapping rule is the same as the CSI-RS in the currently activated BWP or the third BWP described above.

[0295] Further, in the AI-related use case, one AI model can be related to the beam antenna configuration of one or more network side devices. During model inference, by obtaining the beam antenna configuration of the network side device, the terminal can select a suitable AI model for inference, thereby improving the accuracy of model inference. For this purpose, the communication method proposed by the embodiments of the present application can further include: the network side device sends the beam antenna configuration information of the network side device associated with the reference signal resource to the terminal.

[0296] Specifically, the network side device sends the beam antenna configuration information of the network side device associated with the reference signal resource to the terminal, which can include:

[0297] The network side device sends a beam antenna ID associated with the reference signal resource to the terminal, wherein the beam antenna ID is used to indicate the beam antenna configuration information of the network side device associated with the reference signal resource.

[0298] Wherein, the beam antenna configuration information is configured by the network side device through at least one of the following ways:

[0299] The network side device configures a set of beam antenna IDs for each of the reference signal resources, and one beam antenna ID is associated with one beam antenna configuration information.

[0300] The network side device configures a set of common beam antenna IDs for the reference signal resources associated with the same cell, and one beam antenna ID is associated with one beam antenna configuration information.

[0301] Wherein, the beam antenna configuration information can include but is not limited to at least one of the following:

[0302] The number of antenna elements, including the number of horizontal and / or vertical antenna elements;

[0303] The antenna spacing, including the horizontal and / or vertical antenna spacing;

[0305] Antenna height;

[0306] Antenna panel orientation

[0307] Beam pointing

[0308] Half-power beamwidth

[0309] Beamforming codebook, including horizontal and / or vertical beamforming codebook

[0310] Electronic downtilt angle

[0311] Mapping relationship between physical beams and RS identifiers.

[0312] Further, in order to reduce signaling, save communication resources, and improve communication efficiency, the communication method proposed in the embodiments of the present application can further include:

[0313] The network-side device sends fourth information to the terminal, wherein the fourth information is used to indicate that the first reference signal and the second reference signal carried by the reference signal resource have a quasi-co-location (QCL) relationship, and the first reference signal and the second reference signal having the QCL relationship have the same or similar beam antenna configuration information.

[0314] In the embodiments of the present application, the second reference signal can be a reference signal carried by the reference signal resource in the reference signal combination pattern, or can be another reference signal.

[0315] In the embodiments of the present application, the QCL relationship type of the first reference signal and the second reference signal can be any one of QCL-A, QCL-B, QCL-C, and QCL-E, and the embodiments of the present application do not limit this.

[0316] Optionally, in the embodiments of the present application, the QCL relationship type of the first reference signal and the second reference signal is QCL-E. That is, when configuring the first reference signal, the network-side device can configure a new QCL-E relationship to indicate that the first reference signal and the second reference signal have the same beam antenna configuration. For example, the associated ID of the first reference signal (SSB) is 1, and the network-side device indicates that the CSI-RS and the SSB have a QCL-E relationship, so it is considered that the CSI-RS and the SSB have the associated ID of 1.

[0317] In the embodiment of the present application, the reference signal configuration information of at least one interference signal is included in the reference signal combination pattern sent to the terminal, that is, the embodiment of the present application considers the influence of the interference signal on the resource carrying the reference signal. Since the interference is a key factor restricting the quality of the air interface data collection, the quality of the channel measurement information measured by controlling the reference signal introducing the interference signal can be improved, that is, the quality of the collected data can be improved.

[0318] The communication method provided in the embodiment of the present application can be executed by a virtual device. The embodiment of the present application takes the virtual device as an example to execute the communication method, and describes the communication device provided in the embodiment of the present application.

[0319] As shown in FIG. 10, the embodiment of the present application provides a communication device, which can be applied to a terminal. The device 1000 can include a first acquisition module 1001 and a second acquisition module 1002.

[0320] The first acquisition module 1001 is configured to acquire at least one reference signal combination pattern in a signal receiving process, wherein the reference signal combination pattern includes reference signal configuration information of at least one interference signal.

[0321] The reference signal (RS) involved in the reference signal combination pattern can include, but is not limited to, at least one of a channel state information reference signal (CSI-RS), a tracking reference signal (TRS), a demodulation reference signal (DMRS), a sounding reference signal (SRS), and a synchronization signal block (SSB).

[0322] In some embodiments, the reference signal involved in the reference signal combination pattern is a CSI-RS, and correspondingly, the reference signal combination pattern is a CSI-RS combination pattern.

[0323] Generally, since the reference signal combination pattern can give the resource positions of multiple reference signals, the reference signal combination pattern can also be referred to as an RS resource group. For example, when the reference signal combination pattern is a CSI-RS combination pattern, the resource positions of a CSI-RS group are given, and therefore the CSI-RS combination pattern can also be referred to as a CSI-RS resource group.

[0324] In some embodiments, the first obtaining module 1001 can be specifically configured to: obtain, from the network-side device, the reference signal combination pattern in a future time window in a preset time interval in a time domain; and / or obtain, from the network-side device, the reference signal combination pattern in a preset frequency domain resource granularity in a frequency domain.

[0325] In some embodiments, the first obtaining module 1001 can be specifically configured to: obtain at least one reference signal combination pattern in signal reception by DCI, so as to flexibly adjust at least one reference signal combination pattern in signal reception of the terminal in different time periods, thereby performing real-time interference coordination for the terminal. Of course, the terminal can also obtain at least one reference signal combination pattern in signal reception by a radio resource control protocol (RRC).

[0326] The second obtaining module 1002 is configured to obtain channel measurement information based on the at least one reference signal combination pattern.

[0327] For example, the terminal measures a corresponding reference signal according to a reference signal ID or a reference signal resource ID corresponding to the interference pattern ID, to obtain channel measurement information. The obtained channel measurement information can be used for training or inference of an artificial intelligence (AI) model of the terminal. Specifically, the obtained channel measurement information can be used as an input of the AI model of the terminal to train the AI model or to perform inference by using the AI model.

[0328] In the embodiments of the present application, the above-mentioned channel measurement information can include but is not limited to at least one of the following:

[0329] 1) reference signal receiving power (RSRP);

[0330] 2) signal interference noise ratio (SINR);

[0331] 3) CSI, including at least one of a CSI-RS resource indicator (CRI), a rank indication (RI), a precoding matrix indicator (PMI), a channel quality indicator (CQI), and a layer indicator (LI);

[0332] 4) received signal quality;

[0334] 6) power delay profile (PDP);

[0335] 7) delay profile (DP);

[0336] 8) reference signal ID;

[0337] 9) reference signal resource type;

[0338] 10) reference signal resource set ID;

[0339] 11) cell ID;

[0340] 12) TRP ID;

[0341] 13) frequency domain resource, including frequency and bandwidth, such as 2.6G-2.7GHz, 100M;

[0342] 14) timestamp information;

[0343] 15) location information; and

[0344] 16) quality indication information of the above measurement quantities.

[0345] Optionally, the communication device 1000 proposed in the embodiments of the present application can further include a third acquisition module configured to acquire effective time information and validity rules of the reference signal combination pattern from a network side device, so that the terminal performs channel measurement information measurement within the effective time after the reference signal combination pattern takes effect, instead of blind measurement, thereby saving communication resources, improving communication efficiency, and reducing terminal power consumption. The effective time information of the reference signal combination pattern can include an effective duration, and the validity rules of the reference signal combination pattern can be determined by at least one of the following ways: protocol agreement and network side device indication.

[0346] Optionally, the device 1000 can further include a fourth acquisition module configured to acquire first indication information from a network side device after acquiring at least one reference signal combination pattern.

[0347] The first indication information is used to indicate at least one of the following:

[0348] whether at least one RS resource in the reference signal combination pattern is used for the terminal to perform channel information measurement;

[0349] at least one RS resource in the reference signal combination pattern is from a serving cell of the terminal;

[0350] at least one RS resource in the reference signal combination pattern is from a non-serving cell of the terminal, that is, the reference signal combination pattern includes reference signal configuration information of at least one interference signal.

[0351] Optionally, the apparatus 1000 can further include a fifth acquisition module configured to acquire second indication information from a network side device after acquiring at least one reference signal combination pattern.

[0352] The second indication information is used to indicate at least one of the following for each RS resource in the reference signal combination pattern:

[0353] a source cell of the RS carried on the RS resource, the source cell including a serving cell of the terminal or a non-serving cell of the terminal;

[0354] a cell ID associated with the RS resource.

[0355] It can be understood that in the case where a reference signal combination pattern contains both RS resources for carrying RS of a serving cell and RS resources for carrying RS of a non-serving cell (a neighbor cell or an interference cell), the terminal can acquire channel measurement information of a target cell and channel measurement information of interference cells based on the reference signal combination pattern, and the terminal can train an AI model with better generalization performance based on the channel measurement information of the target cell and the channel measurement information of various interference cell combinations.

[0356] Optionally, the reference signal combination pattern is further used to assist training or inference of an AI model of the terminal. For example, the reference signal combination pattern can be specifically used to assist the terminal in selecting a target AI model that matches an interference environment of the network side; and / or the reference signal combination pattern can be specifically used as an input of the target AI model to improve performance of the target AI model.

[0357] It should be noted that, to ensure inference effect, for the target AI model, the reference signal combination pattern selected in the channel information measurement (data acquisition) stage corresponds to the reference signal combination pattern selected in the model inference stage.

[0358] Optionally, each of the reference signal combination patterns is associated with an interference pattern ID, and one interference pattern ID is associated with at least one reference signal ID or reference signal resource ID corresponding to an interference signal. On this basis, the method shown in FIG. 2 can further include: the terminal selects a target AI model matching the interference environment of the network side according to the interference pattern ID corresponding to the reference signal combination pattern, so as to further improve the inference effect of the AI model.

[0359] Further, as shown in FIG. 11, the communication apparatus 1000 proposed by the embodiment of the application can further include:

[0360] The AI inference module 1003 is configured to input the channel measurement information into the target AI model for inference to obtain N inference results, wherein one inference result corresponds to one reference signal combination pattern, and N is a positive integer.

[0361] It can be understood that, since one reference signal combination pattern is associated with one interference pattern ID, N reference signal combination patterns are associated with N interference pattern IDs, and N groups of channel measurement information are obtained by measurement, then N groups of channel measurement information are respectively taken as inputs of the target AI model, and N inference results can be correspondingly obtained.

[0362] The first reporting module 1004 is configured to report first information to a network side device.

[0363] The first information includes at least one of the following:

[0364] The N inference results and the reference signal combination patterns respectively associated with the N inference results;

[0365] Performance indication information of the target AI model under different reference signal combination patterns;

[0366] The N inference results and the cell ID combinations respectively associated with the N inference results;

[0367] Performance indication information of the target AI model under different cell ID combinations.

[0368] It can be understood that, by reporting the above first information to the network side device, the network side device can learn the influence of different reference signal combination patterns (i.e., different interference levels) on the target AI model of the terminal, so as to coordinate the interference formed by the network side to the terminal.

[0369] Optionally, the communication apparatus 1000 proposed by the embodiment of the application can further include: a second reporting module configured to report second information to the network side device. The second information is used to indicate at least one of the following information:

[0370] a cell ID associated with the reference signal combination pattern that the terminal is capable of processing;

[0371] a reference signal combination pattern ID that the terminal is capable of processing;

[0372] a reference signal ID or a reference signal resource ID that the terminal is capable of processing.

[0373] It can be understood that, by reporting the second information to the network side device, the network side device can further understand the actual interference that the terminal is capable of processing, so as to better coordinate the interference formed by the network side to the terminal.

[0374] Optionally, in addition to the reference signal configuration information of at least one interference signal, the reference signal combination pattern further includes reference signal configuration information of at least one serving cell, so as to facilitate the terminal to perform channel measurement information measurement on the serving cell under different interference.

[0375] In some embodiments, in the reference signal combination pattern, the reference signal configuration information of the reference signal of the serving cell or the reference signal of the interference signal can include but is not limited to at least one of the following:

[0376] a reference signal ID or a reference signal resource ID;

[0377] a cell ID associated with the reference signal resource;

[0378] a BWP ID associated with the reference signal resource.

[0379] In some embodiments, the BWP associated with the reference signal resource can be a first BWP in a plurality of candidate BWPs preconfigured by the network side device, that is, a dedicated BWP is specified in the plurality of candidate BWPs preconfigured by the network side device for the terminal to perform channel measurement information measurement; in other embodiments, the BWP can be a second BWP additionally configured by the network side device on the basis of the plurality of candidate BWPs, that is, a dedicated second BWP is additionally configured for the terminal to perform channel measurement information measurement.

[0380] 1) If the BWP associated with the reference signal resource is the first BWP in the plurality of candidate BWPs preconfigured by the network side device, the communication method proposed in the embodiments of the present application can further include:

[0381] The first receiving module is configured to receive third information from a network-side device, wherein the third information is used to instruct the terminal to switch to the first BWP in a plurality of pre-configured candidate BWP, and the information carried by the first BWP can be used for training or inference of an AI model. The third information can be indicated by the network-side device through RRC or DCI.

[0382] For example, as shown in FIG. 4, the network-side device pre-configures a plurality of candidate (dedicated) BWP: BWP1, BWP2, BWP3 and BWP4, and instructs the terminal to switch to BWP3 in the plurality of candidate BWP through RRC or DCI, and adds indication information in the RRC or DCI, indicating that the reference signal carried by BWP3 can be used for data transmission and channel measurement information measurement of the terminal.

[0383] Further, regarding the switching of BWP:

[0384] The communication device 1000 proposed in the embodiments of the present application can further include a BWP switching control module configured to perform at least one of the following:

[0385] a. The terminal determines whether the currently activated BWP is the same as the first BWP, and if so, the terminal does not perform BWP switching;

[0386] b. The terminal determines whether the currently activated BWP is the same as the first BWP, and if not, switches to the first BWP;

[0387] c. The terminal determines whether the currently activated BWP is the same as the first BWP, and if not, switches to the first BWP, and after the expiration of a set timer (Timer), falls back to a default BWP. At the same time, the first BWP is no longer used for channel measurement information measurement of the terminal, and whether the default BWP is used for channel measurement information measurement depends on the configuration of the network-side device on the default BWP.

[0388] Alternatively, the communication device 1000 proposed in the embodiments of the present application can further include a BWP switching control module configured to perform at least one of the following:

[0389] a. The terminal determines whether the first BWP continues to be used for channel information measurement based on fourth indication information contained in the third information;

[0390] b. The terminal does not contain fourth indication information in the third information, and performs at least one of the following:

[0391] determine, according to a protocol agreement, that the first BWP continues to be used for channel information measurement until receiving indication information of deactivating the first BWP;

[0392] determine that the first BWP is no longer used for channel information measurement.

[0393] 2) If the BWP associated with the reference signal resource is the first BWP in the plurality of candidate BWPs pre-configured by the network side device, the communication device 1000 proposed in the embodiment of the application can further include:

[0394] a second receiving module configured to receive fifth information from the network side device, wherein the fifth information is used to activate a third BWP in the plurality of BWPs;

[0395] a third receiving module configured to receive third information from the network side device, wherein the third information is used to activate the first BWP in the plurality of candidate BWPs and indicates that the information carried by the first BWP can be used for AI model training or inference.

[0396] The third information can be indicated by the network side device through RRC or DCI.

[0397] For example, as shown in FIG. 5, the network side device pre-configures a plurality of candidate BWPs: BWP1, BWP2, BWP3 and BWP4. After the network side device indicates the terminal to activate the third BWP-BWP3 through RRC or DCI, the network side device indicates the terminal to activate the first BWP-BWP2 through another indication, wherein the third BWP is used for downlink data transmission, and the first BWP is used for the terminal to measure channel measurement information.

[0398] The pre-configuration of the plurality of candidate BWPs is described in the related art, which is not described herein.

[0399] Further, regarding the switching of the BWP:

[0400] The communication device 1000 proposed in the embodiment of the application can further include a BWP switching control module configured to perform at least one of the following:

[0401] a. The terminal determines whether the currently activated BWP is the same as the third BWP, and if so, the terminal does not perform BWP switching;

[0402] b. The terminal determines whether the currently activated BWP is the same as the third BWP, and if not, switches to the first BWP;

[0403] c. The terminal determines whether the currently activated BWP is the same as the third BWP, and if not, switches to the third BWP, and after a set timer (Timer) expires, falls back to a default BWP.

[0404] And / or, the communication device 1000 proposed in an embodiment of the present application can further include: a BWP switching control module, configured to perform at least one of the following:

[0405] a. The terminal determines whether to activate the first BWP according to the explicit indication of the network side device;

[0406] b. The terminal activates a timer while activating the first BWP according to the indication of the network side device, and deactivates the first BWP after a set timer (Timer) expires. That is, for the first BWP, an activation / deactivation mechanism is adopted.

[0407] As can be seen, in this embodiment, the terminal can activate two BWP at the same time, one for normal data transmission and the other for channel measurement information measurement (or for channel measurement information measurement and normal data transmission), and if no channel measurement information measurement is performed, the first BWP is deactivated, at which time the terminal can run two or more FFT modules at the same time.

[0408] In an embodiment of the present application, the duration of the timer can be configured by the network side device, for example, the duration of the timer can be configured as 10s, 10ms, etc.

[0409] 3) If the BWP associated with the reference signal resource is a second BWP additionally configured by the network side device based on a plurality of candidate BWPs pre-configured, the communication device 1000 proposed in an embodiment of the present application can further include:

[0410] A fourth receiving module for receiving sixth information sent by the network side device, wherein the sixth information is used to configure the second BWP and indicate that the information carried by the second BWP can be used for AI model training or inference.

[0411] For example, as shown in FIG. 6, the network side device pre-configures a plurality of candidate BWPs: BWP1, BWP2, BWP3 and BWP4, and on this basis, the network side device additionally configures a BWP5 for channel measurement information measurement. In FIG. 6, the currently activated BWP3 can be used for downlink data transmission, and the additionally configured and activated BWP5 can be used for channel measurement information measurement.

[0412] Further, regarding the switching of the BWP:

[0413] The communication device 1000 proposed in the embodiments of the present application can further comprise a BWP switching control module configured to perform at least one of the following:

[0414] a. The terminal determines whether the currently activated BWP is the same as the BWP3. If yes, the terminal does not perform BWP switching.

[0415] b. The terminal determines whether the currently activated BWP is the same as the BWP3. If no, the terminal switches to the BWP3.

[0416] c. The terminal determines whether the currently activated BWP is the same as the BWP3. If no, the terminal switches to the BWP3, and after the expiration of a set timer (Timer), the terminal reverts to a default BWP.

[0417] And / or, the communication device 1000 proposed in the embodiments of the present application can further comprise a BWP switching control module configured to perform at least one of the following:

[0418] a. The terminal determines whether to activate the second BWP according to the explicit indication of the network side device.

[0419] b. The terminal activates a timer while activating the second BWP according to the indication of the network side device, and deactivates the second BWP after the expiration of a set timer (Timer). That is, for the second BWP, an activation / deactivation mechanism is adopted.

[0420] As can be seen, in this embodiment, the terminal can activate two BWP at the same time, one for normal data transmission and the other for channel measurement information measurement (or for channel measurement information measurement and normal data transmission). If no channel measurement information measurement is performed, the second BWP is deactivated, and at this time, the terminal can run two or more FFT modules at the same time.

[0421] Optionally, the first BWP, the second BWP, the reference signal on the first BWP and the reference signal on the second BWP can satisfy certain conditions, for example, the adjacent cell interference is less than a first threshold, or the network side considers that the requirements of the terminal for channel measurement information measurement can be met.

[0422] Optionally, the first BWP or the second BWP can be used for normal downlink data transmission in addition to being used for the terminal to perform channel measurement information measurement, such as various PDCCH configurations and PDSCH configurations, and the like; of course, the first BWP or the second BWP can also be used only for reference signal configuration, and no signal is transmitted on the time-frequency resource outside the reference signal resource (such as the power of the reference signal transmission can be lifted, etc.); or the first BWP or the second BWP can be used entirely for transmitting reference signals.

[0423] It can be understood that after the first BWP or the second BWP is configured and activated, the terminal can perform channel measurement information measurement based on the reference signals on the first BWP or the second BWP.

[0424] The configuration and switching of the BWP related to the embodiments of the present application are described above.

[0425] Optionally, the communication device 1000 proposed in the embodiments of the present application can further include:

[0426] The fifth receiving module is configured to receive a first parameter configured by the network side device, wherein the first parameter is used to indicate the frequency domain density and the period of the BWP (such as the first BWP or the second BWP) associated with the reference signal resource in the reference signal combination pattern, so as to facilitate the terminal to accurately measure the reference signals on the reference signal resources.

[0428] The absolute frequency domain density and the absolute period of the BWP;

[0429] The relative frequency domain density and the relative period of the BWP;

[0431] For example, assuming that the reference signal involved in the reference signal combination pattern is CSI-RS, the density of the frequency domain of the first BWP or the second BWP can be configured better, and the period of the time domain of the first BWP or the second BWP can be configured smaller, and the first parameter is configured as follows:

[0432] a. The absolute frequency domain density and the absolute period, such as the frequency domain density being 6 and the absolute period being 1ms;

[0453] The seventh acquisition module is configured to acquire fourth information from the network side device, wherein the fourth information is used to indicate that the first reference signal and the second reference signal carried by the reference signal resource have a quasi co location (QCL) relationship, and the first reference signal and the second reference signal having the QCL relationship have the same or similar beam antenna configuration information.

[0454] In the embodiments of the present application, the second reference signal can be a reference signal carried by the reference signal resource in the reference signal combination pattern, or can be another reference signal.

[0455] In the embodiments of the present application, the QCL relationship type of the first reference signal and the second reference signal can be any one of QCL-A, QCL-B, QCL-C, and QCL-E, and the embodiments of the present application do not limit this.

[0456] Optionally, in the embodiments of the present application, the QCL relationship type of the first reference signal and the second reference signal is QCL-E. That is, when configuring the first reference signal, the network side device can configure a new QCL-E relationship to indicate that the first reference signal and the second reference signal have the same beam antenna configuration. For example, the associated ID of the first reference signal SSB is 1, and the network side device indicates that the CSI-RS and the SSB have a QCL-E relationship, and it is considered that the CSI-RS and the SSB have the associated ID of 1.

[0496] It should be noted that, in order to ensure the inference effect, for the target AI model, the reference signal combination pattern selected in the channel information measurement stage corresponds to the reference signal combination pattern selected in the model inference stage.

[0497] Optionally, each reference signal combination pattern is associated with an interference pattern ID, and one interference pattern ID is associated with at least one reference signal ID or reference signal resource ID corresponding to an interference signal. On this basis, the corresponding terminal selects a target AI model that matches the interference environment of the network side according to the interference pattern ID corresponding to the reference signal combination pattern, to further improve the inference effect of the AI model.

[0498] Further, the communication device 1200 proposed in the embodiment of the present application can further include:

[0499] The first receiving module is configured to receive first information reported by the terminal, wherein the first information is sent by the terminal after acquiring channel measurement information according to the reference signal ID or reference signal resource ID corresponding to the interference pattern ID, inputting the channel measurement information into a target AI model for inference, and obtaining N inference results, one inference result corresponding to one reference signal combination pattern, and N being a positive integer.

[0504] Performance indication information of the target AI model under different cell ID combinations.

[0505] It can be understood that the terminal reports the first information to the network side device, which can enable the network side device to understand the influence of different reference signal combination patterns (i.e., different interference levels) on the target AI model of the terminal, thereby coordinating the interference formed by the network side to the terminal.

[0506] Further, the communication device 1200 proposed in the embodiment of the present application can further include a second receiving module configured to receive second information reported by the terminal, wherein the second information is used to indicate at least one of the following information:

[0517] 1) If the BWP associated with the reference signal resource is the first BWP in the plurality of pre-configured candidate BWPs of the network-side device, the communication apparatus 1200 proposed in the embodiments of the present application can further include:

[0518] A fifth sending module configured to send third information to the terminal, wherein the third information is used to instruct the terminal to switch to the first BWP in the plurality of pre-configured candidate BWPs, and the information carried by the first BWP can be used for AI model training or inference. The third information can be indicated by the network-side device through RRC or DCI.

[0519] For example, as shown in FIG. 4, the network-side device pre-configures a plurality of candidate BWPs: BWP1, BWP2, BWP3 and BWP4, and instructs the terminal to switch to BWP3 in the plurality of candidate BWPs through RRC or DCI, and adds indication information in the RRC or DCI, indicating that the reference signal carried by BWP3 can be used for terminal data transmission and channel measurement information measurement.

[0526] A seventh sending module is configured to send sixth information to the terminal, wherein the sixth information is used to configure the second BWP and indicate that the information carried by the second BWP can be used for AI model training or inference.

In FIG. 6, the currently activated BWP3 can be used for downlink data transmission, and the additionally configured and activated BWP5 can be used for channel measurement information measurement.

[0528] Optionally, the first BWP, the second BWP, the reference signal on the first BWP and the reference signal on the second BWP can meet certain conditions, for example, the adjacent cell interference is less than a first threshold, or the network side believes that the requirement of the terminal to perform channel measurement information measurement can be met.

[0529] Optionally, the first BWP or the second BWP can be used not only for the terminal to perform channel measurement information measurement, but also for normal downlink data transmission, such as various PDCCH configurations and PDSCH configurations and the like; of course, the first BWP or the second BWP can be used only for reference signal configuration, and no signal is transmitted on the time-frequency resource outside the reference signal resource (such as the power of the reference signal transmission can be raised); or the first BWP or the second BWP can be used entirely for transmitting reference signals.

[0530] It can be understood that after the first BWP or the second BWP is configured and activated, the terminal can perform channel measurement information measurement based on the reference signal on the first BWP or the second BWP.

[0534] The relative frequency domain density and the relative period of the BWP;

[0536] For example, assuming that the reference signals involved in the reference signal combination pattern are CSI-RS, the first BWP or the second BWP can be configured with a higher density in the frequency domain and a smaller period in the time domain, and the specific configuration is as follows:

[0537] a. The absolute frequency domain density and the absolute period, such as a frequency domain density of 6 and an absolute period of 1 ms;

[0538] b. The relative frequency domain density and the relative period, such as a density of M times that of the currently activated BWP or the third BWP and a period of 1 / N of that of the currently activated BWP or the third BWP;

[0539] c. The resource mapping rule can follow the existing protocol, or by default, the resource mapping rule is the same as that of the CSI-RS in the currently activated BWP or the third BWP.

[0559] In the embodiments of the present application, the second reference signal can be a reference signal carried by a reference signal resource in the reference signal combination pattern, or can be another reference signal.

[0560] In the embodiments of the present application, the QCL relationship type between the first reference signal and the second reference signal can be any one of QCL-A, QCL-B, QCL-C and QCL-E, and the embodiments of the present application do not make any limitation.

[0561] Optionally, in the embodiments of the present application, the QCL relationship type between the first reference signal and the second reference signal is QCL-E. That is, when configuring the first reference signal, the network side device can configure a new QCL-E relationship to indicate that the first reference signal and the second reference have the same beam antenna configuration. For example, the associated ID of the first reference signal SSB is 1, and the network side device indicates that the CSI-RS and the SSB have a QCL-E relationship, and then it is considered that the CSI-RS and the SSB associated ID = 1.

[0562] In the embodiments of the present application, the reference signal configuration information of at least one interference signal in the reference signal combination pattern sent to the terminal, that is, the embodiments of the present application consider the influence of the interference signal on the resource carrying the reference signal.
