Description

Communication methods and communication equipment Technical Field

[0001] This application relates to the field of communication technology, and more specifically, to a communication method and communication device. Background Technology

[0002] In related technologies, network devices can use channel state information (CSI) reporting configuration to instruct a first CSI report, which is used by terminal devices to provide feedback on CSI obtained based on inference. Simultaneously, network devices can use another CSI reporting configuration to instruct a second CSI report, which is used by terminal devices to perform performance monitoring on the inference and report the performance monitoring results. These two CSI reports can utilize independent CSI measurement resources and CSI reporting resources.

[0003] However, in related technologies, after the terminal device completes CSI reporting, it terminates the activation of the corresponding channel measurement resources and the occupation of the CSI processing unit (CPU), causing the terminal device to discard the CSI measurement results and reported content corresponding to the first CSI. As a result, when the terminal device performs performance monitoring, it cannot complete the performance monitoring process because there are no previously inferred results to compare.

The wireless communication system 100 may include a network device 110 and a terminal device 120. The network device 110 may be a device that communicates with the terminal device 120. The network device 110 can provide network coverage for a specific geographical area and can communicate with the terminal device 120 located within that coverage area. The terminal device 120 can access a network (such as a wireless network) through the network device 110. Optionally, the wireless communication system 100 may also include other network entities such as a network controller and a mobility management entity; this embodiment of the application does not limit this.

[0035] It should be understood that the technical solutions of the embodiments of this application can be applied to various communication systems, such as 5G systems or new radio (NR), long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, etc. The technical solutions provided in this application can also be applied to future communication systems, such as sixth-generation mobile communication systems, satellite communication systems, and so on.

[0036] The terminal device in this application embodiment can also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station (MS), mobile terminal (MT), remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device. The terminal device in this application embodiment can be a device that provides voice and / or data connectivity to a user, and can be used to connect people, objects, and machines, such as a handheld device with wireless connectivity, vehicle-mounted device, etc. The terminal devices in the embodiments of this application can be mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, self-driving, remote medical surgery, smart grids, transportation safety, smart cities, and smart homes, etc. Optionally, the terminal device can act as a base station. For example, the terminal device can act as a scheduling entity, providing sidelink signals between terminal devices in vehicle-to-everything (V2X) or device-to-device (D2D) systems. For instance, cellular phones and cars communicate with each other using sidelink signals. Cellular phones and smart home devices communicate without relaying communication signals through base stations.

[0037] The network device in this application embodiment can be a device for communicating with terminal devices. This network device can be, for example, an access network device or a wireless access network device. For instance, the network device can be a base station. The term "base station" can broadly encompass various names, or be replaced by, the following: NodeB, evolved NodeB (eNB), next-generation NodeB (gNB), relay station, access point, transmitting and receiving point (TRP), transmitting point (TP), home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. A base station can be a macro base station, micro base station, relay node, donor node, or the like, or a combination thereof.

[0038] Downlink CSI Feedback

[0039] To enable network devices to perform reasonable scheduling, terminal devices need to report downlink CSI (Content Status Indicator) information. This allows the network devices to determine the terminal device's scheduling information, such as the transmission layer number, precoding matrix, transmit beam, and modulation / coding scheme. Terminal device CSI reporting is based on the CSI reporting configuration indicated by the network device and the channel state information reference signal (CSI-RS) signal transmitted by the network device. The uplink resources used by the terminal device for CSI reporting and the CSI-RS signal used for CSI measurement are both indicated by the CSI reporting configuration. Each CSI reporting configuration corresponds to one CSI report, and each CSI report can include different information such as the CSI-RS resource indicator (CRI), rank indicator (RI), precoding matrix indicator (PMI), and channel quality indicator (CQI). This information is obtained based on the CSI-RS signal configured and transmitted by the network device. The content or information that should be included in the CSI report can be determined by the report quantity information in the CSI reporting configuration. For example, the reporting volume information can indicate one or more of the following reporting volumes:

[0040] Among them, CRI is used to determine the CSI-RS resource currently used for channel measurement and the interference measurement resource (IMR) currently used for interference measurement from multiple CSI-RS resources; RI is used to report the recommended number of transmission layers; PMI is used to determine the recommended precoding matrix from a predefined codebook; CQI is used to report the current channel quality; Reference signal receiving power (RSRP) is used to report the synchronization signal block (SSB) or RSRP of the CSI-RS corresponding to the fed-out index, so as to determine the beam used for downlink transmission on the network side; and Layer indicator (LI) is used to report the index of the transmission layer associated with the phase-tracking reference signal (PTRS).

[0041] In the aforementioned reported quantities, RI, PMI, and CQI can be determined based on the signal-to-interference plus noise ratio (SINR) estimated by the terminal. The channel component of SINR is determined based on the non-zero power CSI-RS configured by the network device for channel measurement, while the interference component is determined based on CSI interference measurement (CSI-IM) or a non-zero power CSI-RS configured by the network device for interference measurement. The CSI-RS resource used for channel measurement can include multiple antenna ports, and this CSI-RS resource can be used to measure the complete downlink channel to calculate the CSI.

[0042] Terminal devices can report CSI in three ways: periodic CSI, semi-periodic CSI, and aperiodic CSI, as shown in Figure 2. Periodic CSI is transmitted on the physical uplink control channel (PUCCH), and its CSI reporting configuration is configured by radio resource control (RRC). After receiving the corresponding RRC configuration, the terminal device periodically reports CSI. Semi-periodic CSI can be transmitted on the PUCCH or the physical uplink shared channel (PUSCH). The CSI reporting configuration corresponding to CSI transmitted on the PUCCH is pre-configured by RRC signaling and activated or deactivated by media access control (MAC) layer signaling. The CSI reporting configuration corresponding to CSI transmitted on the PUSCH is dynamically indicated (activated or deactivated) by downlink control information (DCI) signaling. After receiving activation or indication signaling from the network configuration, the terminal device periodically transmits CSI on the PUCCH or PUSCH until it receives deactivation signaling and stops reporting. The CSI reporting configuration for non-periodic CSI reporting is also pre-configured via RRC signaling. Part of the configuration can be activated via MAC layer signaling, and the CSI reporting configuration used for CSI reporting can be indicated via CSI trigger signaling in the DCI. Upon receiving the CSI trigger signaling, the terminal device can report the corresponding CSI on the scheduled PUSCH in one go according to the indicated CSI reporting configuration.

[0043] Reasoning-based CSI Feedback

[0044] Artificial intelligence (AI) technology, especially deep learning, has achieved tremendous success in computer vision and natural language processing. Therefore, the communications field has begun to explore using deep learning to solve technical challenges that traditional communication methods struggle with. The neural network architecture commonly used in deep learning is non-linear and data-driven, capable of extracting features from actual channel matrix data and reconstructing the compressed channel matrix information from the terminal device as accurately as possible on the network device side. This not only ensures accurate channel information reproduction but also reduces CSI feedback overhead on the terminal device side. Deep learning-based CSI feedback treats channel information as an image to be compressed, using a deep learning autoencoder to compress the input channel information and then reconstructing the compressed channel image at the receiving end, thus preserving channel information to a greater extent.

[0045] One basic implementation framework for reasoning-based CSI feedback is described below. This framework employs an AI-based CSI autoencoder, dividing the entire feedback system into an encoder and a decoder, deployed on the terminal device and network device sides respectively. After obtaining channel information through channel estimation, the terminal device uses this information as input to the encoder. The encoder's neural network then compresses and encodes the channel information matrix, feeding the compressed bitstream back to the network device via an air interface feedback link. The network device, through the decoder, reconstructs the channel information based on the feedback bitstream and outputs complete feedback channel information. The neural networks of the encoder and decoder shown in Figure 3 can employ deep neural networks (DNNs) composed of multiple fully connected layers, convolutional neural networks (CNNs) composed of multiple convolutional layers, recurrent neural networks (RNNs) with structures such as long short-term memory (LSTM) and gated recurrent units (GRUs), or various neural network architectures such as residual and self-attention mechanisms to improve the performance of the encoder and decoder.

[0046] Inference-based CSI feedback can also be deployed solely on the terminal device side, reducing reliance on dual-end models. For example, as shown in Figure 4, the terminal device can obtain channel information corresponding to N antenna ports based on channel information from M antenna ports and a trained AI model, where N>M, thereby reducing reference signal overhead. In another application scenario, the terminal device can predict channel information corresponding to multiple future time points based on channel information from previous time points and a trained AI model, thus reducing CSI latency. In these scenarios, the AI ​​model only needs to be deployed on the terminal device side; therefore, the terminal device can also use some optimized traditional methods to implement the AI ​​model's functionality, thus avoiding the model lifecycle management (LCM) process. For example, the terminal device can generate filter coefficients, calculate the correlation matrix used for interpolation, and implement the AI ​​model's functionality using traditional filters or interpolation functions.

[0047] In reasoning-based CSI feedback, regardless of whether AI technology is used, the terminal device needs to perform a reasoning process to acquire CSI. For example, in Figure 4, channel information for N antenna ports is inferred from channel information of M antenna ports, and channel information for k subsequent time points is inferred from channel information of m previous time points. To ensure the reliability of this reasoning, performance monitoring is required. The terminal device compares the actually measured channel information with the inferred results to determine the accuracy of the reasoning process. If the two are consistent or have a high similarity, the reasoning is reliable; otherwise, the reasoning is unreliable, and the terminal device needs to update the AI ​​model, filter, or interpolation function used for reasoning to improve its accuracy. For example, the network device can send a CSI-RS resource for N antenna ports for performance monitoring. The terminal device then compares the measured channel information of N antenna ports with the channel information of N antenna ports inferred from the channel information of M antenna ports, determines the reliability of the reasoning based on the calculated cosine similarity (SGCS), and reports the performance monitoring results.

[0048] In related technologies, network devices can configure CSI reporting to instruct a first CSI report, which is used by terminal devices to provide feedback on CSI obtained based on inference. Simultaneously, network devices can configure another CSI reporting to instruct a second CSI report, which is used by terminal devices to perform performance monitoring on the inference and report the performance monitoring results. These two CSI reports can utilize independent CSI measurement resources and CSI reporting resources.

[0049] However, in related technologies, after the terminal device completes CSI reporting, it terminates the activation of the corresponding channel measurement resources and the occupation of the CSI processing unit, causing the terminal device to discard the CSI measurement results and reported content corresponding to the first CSI. As a result, when the terminal device performs performance monitoring, it cannot complete the performance monitoring process because there are no previously inferred results to compare.

[0050] To address the aforementioned issues, the embodiments of this application will be described in detail below with reference to Figure 5.

[0051] Figure 5 is a schematic flowchart of the communication method provided in an embodiment of this application. The method in Figure 5 is described from the perspective of the interaction between the terminal device and the network device. The terminal device and network device shown in Figure 5 can be any type of terminal device and network device mentioned above (see Figure 1).

[0052] Referring to Figure 5, in step S510, the terminal device reports the first CSI based on the configuration of the network device.

[0053] Before step S510, the network device can configure the terminal device to perform the first CSI report. For example, the network device can instruct the terminal device to perform the first CSI report through CSI reporting configuration. This CSI reporting configuration can include one or more of the following information: CSI measurement resources corresponding to the first CSI report, CSI reporting resources, reporting quantity, CSI measurement method, etc. Accordingly, the terminal device can receive this CSI reporting configuration information. The terminal device performing the first CSI report based on the network device's configuration, as mentioned in step S510, can include: the terminal device performing the first CSI report based on the CSI reporting configuration sent by the network device.

[0054] In addition to the first CSI report, the network device can also configure the terminal device to perform a second CSI report. For example, the network device can instruct the terminal device to perform a second CSI report through a CSI reporting configuration. This CSI reporting configuration can be two different CSI reporting configurations from the one corresponding to the first CSI report. The CSI reporting configuration corresponding to the second CSI report can include one or more of the following information: CSI measurement resources corresponding to the second CSI report, CSI reporting resources, reporting quantity, CSI measurement method, and the associated CSI reporting configuration identifier corresponding to the first CSI report, etc. Accordingly, the terminal device can receive the CSI reporting configuration corresponding to the second CSI report. Then, the terminal device can perform the second CSI report based on the CSI reporting configuration corresponding to the second CSI report.

[0055] In some implementations, the network device can send configuration information to the terminal device. Accordingly, before the first CSI report, the terminal device can receive the configuration information sent by the network device. This configuration information can be used to indicate the association between the CSI reporting configuration corresponding to the first CSI report and the CSI reporting configuration corresponding to the second CSI report. Alternatively, the configuration information can be used to indicate the association between the first CSI report and the second CSI report. This configuration information can be a separate configuration, or it can be included in the CSI reporting configuration corresponding to the first CSI report, or it can be included in the CSI reporting configuration corresponding to the second CSI report, or it can be included in both the CSI reporting configurations corresponding to the first and second CSI reports. After receiving this configuration information, the terminal device can determine the association between the first and second CSI reports, or the association between the CSI reporting configuration corresponding to the first CSI report and the CSI reporting configuration corresponding to the second CSI report, based on this configuration information.

[0056] For example, the CSI reporting configuration corresponding to the first CSI report may include a CSI reporting configuration identifier associated with the CSI report. This CSI reporting configuration identifier indicates the CSI reporting configuration corresponding to the second CSI report. The terminal device can determine that the first CSI report and the second CSI report are associated based on this CSI reporting configuration identifier, that is, the second CSI report is used to provide feedback on the performance monitoring results of the first CSI report.

[0057] For example, the CSI reporting configuration corresponding to the second CSI report may include a CSI reporting configuration identifier associated with the first CSI report. This CSI reporting configuration identifier indicates the CSI reporting configuration corresponding to the first CSI report. The terminal device can determine that the first CSI report and the second CSI report are associated based on this CSI reporting configuration identifier, that is, the second CSI report is used to provide feedback on the performance monitoring results of the first CSI report.

[0058] For example, if the first CSI report is based on an AI model, and the second CSI report is used to provide feedback on the performance monitoring results of the AI ​​model used in the first CSI report, then an identification information can be included in the CSI report configuration corresponding to both the first and second CSI reports. This identification information can be used to identify the AI ​​model. When the identification information included in the CSI report configuration corresponding to the first and second CSI reports is the same, it indicates that they are based on the same AI model. Therefore, it can be determined that the first and second CSI reports are associated, meaning that the second CSI report is used to provide feedback on the performance monitoring results of the AI ​​model used in the first CSI report.

[0059] In one implementation, the second CSI report can be used to provide feedback on the performance monitoring results associated with the first CSI report. For example, at least part of the content reported in the first CSI report is based on inference. In this case, the second CSI report is used to provide feedback on the performance monitoring results of the inference process associated with the first CSI report. The inference process mentioned here can be implemented based on AI models, interpolation functions, or filters, and how it is implemented depends on the specific implementation of the terminal device. The inference process may include: the terminal device infers target channel information based on the measured initial channel information, and determines the reporting content corresponding to the first CSI report based on the target channel information. For example, the initial channel information includes channel information of M antenna ports, and the target channel information includes channel information of N antenna ports (M and N are both positive integers, and N > M). Another example is that the initial channel information includes channel information of M sub-bands, and the target channel information includes channel information of N sub-bands (M and N are both positive integers, and N > M). Yet another example is that the initial channel information includes channel information from multiple previous time points, and the target channel information includes channel information corresponding to multiple future time points.

[0060] The "second CSI report used to provide feedback on the performance monitoring results of the inference process reported by the first CSI" mentioned earlier can refer to the second CSI report being used to provide feedback on the performance monitoring results of the inference process reported by the first CSI, thereby determining the accuracy of the inference process. For example, the terminal device can compare the channel information obtained from actual measurements with the inference results to determine whether the inference process is accurate. As an example, the terminal device can measure the reference signals of N antenna ports to obtain the channel information of N antenna ports; then, the terminal device compares the channel information of these N antenna ports with the channel information of the N antenna ports obtained from inference, and calculates the similarity between the two (for example, it can be measured by SGCS); then, the terminal device can compare the value of this similarity with a threshold value to determine the reliability of the inference process. The second CSI report can directly report the value of this similarity (such as the average SGCS), or it can report the final result of the performance monitoring (such as whether the SGCS is higher than the threshold value or the percentage of the SGCS that is higher than the threshold value).

[0061] If the first CSI report mentioned above is associated with the second CSI report, the activation time of the channel measurement resources corresponding to the first CSI report and / or the time occupied by the CSI processing unit for the first CSI report can be appropriately adjusted so that the reported content corresponding to the first CSI report can be used for subsequent performance monitoring (i.e., performance detection corresponding to the second CSI). The following examples, in conjunction with Embodiment 1 and Embodiment 2, provide a more detailed illustration of this.

[0062] Example 1: Activation time of the channel measurement resources corresponding to the first CSI report

[0063] In Embodiment 1, when the first CSI report is associated with the second CSI report, the activation time of the channel measurement resource corresponding to the first CSI report includes at least one time-domain resource unit after the first CSI report. The time-domain resource unit mentioned in this embodiment includes OFDM symbols, time slots, or other time-domain resource units.

[0064] The channel measurement resources mentioned in the embodiments of this application can refer to resources used to measure or acquire channel information. These channel measurement resources can be, for example, CSI-RS, such as a non-zero power CSI-RS.

[0065] The activation time of the channel measurement resource corresponding to the first CSI report mentioned above, including at least one time-domain resource unit after the first CSI report, can be implemented in various ways. Several examples are given below.

[0066] Example 1:

[0067] The activation time of the channel measurement resources corresponding to the first CSI report mentioned above includes at least one time-domain resource unit after the first CSI report, which may include: the activation time of the channel measurement resources corresponding to the first CSI report starts from the first OFDM symbol and ends after K time-domain resource units following the first CSI report. The K time-domain resources mentioned here may be, for example, K time slots or K symbols. The value of K can be determined based on protocol predefined information, the capability reporting of the terminal device, and / or the configuration information of the network device. For example, K may be a value pre-agreed upon by the terminal device and the network device.

[0068] Taking Figure 6 as an example, the activation time of the channel measurement resource corresponding to the first CSI report starts from the first OFDM symbol and ends K time slots or symbols after the first CSI report.

[0069] It should be noted that if the first CSI report is a periodic CSI report or a semi-continuous CSI report, the activation time can be calculated separately for each CSI report.

[0070] Example 2:

[0071] The activation time of the channel measurement resource corresponding to the first CSI report mentioned above includes at least one time-domain resource unit after the first CSI report, and may include: the activation time starting from the first OFDM symbol and ending after the second CSI report is completed. If there are multiple second CSI reports after the first OFDM symbol, the second CSI report mentioned here may refer to the second CSI report closest to the first OFDM (or first CSI report). The distance mentioned here refers to the distance in the time domain.

[0072] Referring to Figure 7, in the example in Figure 7, the first CSI report is a periodic or semi-periodic CSI report. The activation time of the channel measurement resource corresponding to the first CSI report ends after the completion of the most recent second CSI report after the first OFDM symbol.

[0073] Referring to Figure 8, in the example in Figure 8, the first CSI report is an aperiodic CSI report. The activation time of the channel measurement resource corresponding to the first CSI report ends after the corresponding second CSI report is completed.

[0074] Example 3:

[0075] The activation time of the channel measurement resource corresponding to the first CSI report mentioned above includes at least one time-domain resource unit after the first CSI report, which may include: the first CSI report is used for CSI prediction, and the activation time of the channel measurement resource corresponding to the first CSI report starts from the first OFDM symbol and ends at the last time-domain resource unit of the first CSI report prediction. As shown in Figure 9, the last time-domain resource unit of the first CSI report prediction can be the last time slot of the CSI prediction window or the last OFDM symbol of the CSI prediction window.

[0076] The preceding text detailed the method for determining the activation time of the channel measurement resources corresponding to the first CSI report when the first CSI report is associated with the second CSI report. In another implementation, when the first CSI report is not associated with the second CSI report, the activation time of the channel measurement resources corresponding to the first CSI report can start from the first OFDM symbol and end after the first CSI report is completed, or it can continue for several time-domain resource units (time slots or OFDM symbols) starting from the first OFDM symbol.

[0077] For example, if the first CSI report is not associated with the second CSI report, that is, if the measurement result of the first CSI report is not used for performance monitoring, the activation time of the channel measurement resource corresponding to the first CSI report can be shortened accordingly, ending after the first CSI report is completed, or continuing for several time slots or OFDM symbols starting from the first OFDM symbol.

[0078] This application does not specifically limit the definition of the first OFDM symbol mentioned above in the embodiments. For example, the first OFDM is: the first OFDM symbol after the terminal receives downlink signaling for configuring or activating the channel measurement resources corresponding to the first CSI report. Another example is: the first OFDM symbol of the time slot containing the channel measurement resources corresponding to the first CSI report. Yet another example is: the first OFDM symbol occupied by the channel measurement resources corresponding to the first CSI report. And yet another example is: the last OFDM symbol occupied by the channel measurement resources corresponding to the first CSI report.

[0079] In some implementations, the terminal device can determine the number of currently active channel measurement resources based on the activation time of the corresponding channel measurement resource reported in the first CSI, and will stop processing additional channel measurement resources once the number reaches the maximum number supported by the terminal device. In other words, the terminal device can stop measuring additional channel measurement resources. Correspondingly, the network device determines the number of currently active channel measurement resources based on the activation time of the corresponding channel measurement resource reported in the first CSI, ensuring that the number does not exceed the maximum number supported by the terminal device. That is, once the number of currently active channel measurement resources reaches the maximum number supported by the terminal device, the network device will not activate any new channel measurement resources. The maximum number of active channel measurement resources supported by the terminal device mentioned here can, for example, be reported by the terminal device to the network device through the terminal device capability reporting process.

[0080] In this embodiment, when the first CSI report is associated with the second CSI report, that is, when the measurement result of the first CSI report is also used for performance monitoring, the activation time of the channel measurement resource corresponding to the first CSI report includes at least one time-domain resource unit after the first CSI report. In this way, after the terminal device completes the first CSI report, it will not immediately release the memory used to store the CSI measurement result, but will continue to save at least one time-domain resource unit. Thus, in the subsequent calculation of the performance monitoring result of the second CSI report, the terminal device can use the previously inferred CSI measurement result for performance monitoring.

[0081] Example 2: Regarding the time occupied by the first CSI report in the CSI processing unit

[0082] In Embodiment 2, when the first CSI report is associated with the second CSI report, the time occupied by the first CSI report in the CSI processing unit includes at least one time-domain resource unit after the first CSI report.

[0083] The time-domain resource units mentioned in the various embodiments of this application include OFDM symbols, time slots, or other time-domain resource units.

[0084] The activation time of the channel measurement resource corresponding to the first CSI report mentioned above, including at least one time-domain resource unit after the first CSI report, can be implemented in various ways. Several examples are given below.

[0085] Example 1:

[0086] The time occupied by the first CSI report in the CSI processing unit mentioned above includes at least one time-domain resource unit after the first CSI report, which can include: the time occupied by the first CSI report from the second OFDM symbol to the end of M time-domain resource units after the first CSI report. The M time-domain resources mentioned here can be, for example, M time slots or M symbols. The value of M can be determined based on protocol predefined information, the capability reporting of the terminal device, and / or the configuration information of the network device. For example, M can be a value pre-agreed upon by the terminal device and the network device.

[0087] Taking Figure 10 as an example, the time occupied by the first CSI report in the CSI processing unit starts from the second OFDM symbol and ends M time slots or symbols after the first CSI report.

[0088] It should be noted that if the first CSI report is a periodic CSI report or a semi-continuous CSI report, the time of the corresponding CSI processing unit can be calculated separately for each CSI report.

[0089] Example 2:

[0090] The time occupied by the first CSI report in the CSI processing unit mentioned above includes at least one time-domain resource unit after the first CSI report, which may include: the time occupied by the first CSI report in the CSI processing unit starts from the second OFDM symbol and ends after the second CSI report is completed. If there are multiple second CSI reports after the second OFDM symbol, the second CSI report mentioned here may refer to the second CSI report that is closest (in the time domain) to the first OFDM (or the first CSI report).

[0091] Referring to Figure 11, in the example of Figure 11, the first CSI report is a periodic or semi-periodic CSI report. The time occupied by the first CSI report in the CSI processing unit ends after the most recent second CSI report is completed, following the second OFDM symbol.

[0092] Referring to Figure 12, in the example of Figure 12, the first CSI report is an aperiodic CSI report. The time occupied by the first CSI report in the CSI processing unit ends after the corresponding second CSI report is completed.

[0093] Example 3:

[0094] The time occupied by the first CSI report in the CSI processing unit mentioned above includes at least one time-domain resource unit after the first CSI report, which may include: the first CSI report is used for CSI prediction, and the time occupied by the first CSI report in the CSI processing unit starts from the second OFDM symbol and ends at the last time-domain resource unit of the first CSI report prediction. As shown in Figure 13, the last time-domain resource unit of the first CSI report prediction can be the last time slot of the CSI prediction window or the last OFDM symbol of the CSI prediction window.

[0095] The preceding text detailed how to determine the time the first CSI report occupies the CSI processing unit when the first CSI report is associated with the second CSI report. In another implementation, when the first CSI report is not associated with the second CSI report, the time the first CSI report occupies the CSI processing unit begins from the second OFDM symbol and ends after the first CSI report is completed. That is, when the first CSI report is not associated with the second CSI report, i.e., when the measurement results reported by the first CSI are not used for performance monitoring, the time the first CSI report occupies the CSI processing unit can be shortened accordingly, ending after the first CSI report is completed.

[0096] This application does not specifically limit the definition of the second OFDM symbol mentioned above in the embodiments. For example, the second OFDM symbol is: the first OFDM symbol after the terminal receives downlink signaling used to configure or trigger the first CSI report. Another example is the first OFDM symbol occupied by the CSI measurement resources corresponding to the first CSI report. Yet another example is the last OFDM symbol occupied by the CSI measurement resources corresponding to the first CSI report. The CSI measurement resources mentioned here may include channel measurement resources such as CSI-RS / SSB, and interference measurement resources such as CSI-IM.

[0097] In one implementation, for periodic or semi-persistent CSI reporting (not the first report), the second OFDM symbol is the first OFDM symbol occupied by the CSI measurement resources corresponding to the first CSI report, wherein the first CSI report for different periods may correspond to different CSI measurement resources. For semi-persistent (first report) or non-periodic CSI reporting, the second OFDM symbol may be the first OFDM symbol after the terminal receives the DCI signaling used to activate / trigger the first CSI report.

[0098] In some implementations, the terminal device determines the number of currently occupied CSI processing units based on the time the first CSI report occupies the CSI processing unit. When this number reaches the maximum number of CSI processing units supported by the terminal device, no further CSI reports are processed. In other words, for CSI reports exceeding the maximum number, the terminal device may choose not to report, or report but not update the CSI. Correspondingly, the network device determines the number of currently occupied CSI processing units based on the time the first CSI report occupies the CSI processing unit, ensuring that the number does not exceed the maximum number of CSI processing units supported by the terminal device. That is, once the number of currently occupied CSI processing units reaches the maximum number supported by the terminal device, the network device will not activate / trigger new CSI reports. The maximum number of CSI processing units supported by the terminal device mentioned here can, for example, be reported to the network device by the terminal device through terminal capabilities.

[0099] In this embodiment, when the first CSI report is associated with the second CSI report, that is, when the measurement result of the first CSI report is also used for performance monitoring, the time occupied by the CSI processing unit for the first CSI report includes at least one time-domain resource unit after the first CSI report. In this way, after the terminal device completes the first CSI report, it will not immediately release the corresponding CSI processing unit, but will continue to occupy at least one time-domain resource unit. Thus, in the subsequent calculation of the performance monitoring result of the second CSI report, the terminal device can continue to calculate for performance monitoring based on the previous CSI measurement result.
