[0003] With the development of artificial intelligence (AI) technology, AI modules may be used to replace some traditional functional modules in wireless communication systems. Since AI technology is data-driven, its performance is closely related to the data. Therefore, when the characteristics of the data differ significantly from those of the AI's training data, or when the data is not distributed in the same way as the training data, the performance of the AI ​​module may be poor.

[0004] Therefore, after introducing an AI module into a wireless communication system, it is necessary to monitor the performance of the AI ​​module. Summary of the Invention

[0007] In this way, the first device can send a CSI report based on the first configuration information sent by the second device, and receive the first information sent by the second device. The first information can be used to instruct the first device to adjust the proportion of sending CSI reports using the first mode and / or the second mode. This technical solution can monitor the performance of the first device in the two modes with less overhead. Furthermore, it can adjust the proportion of sending CSI reports using the two modes in real time or near real time.

[0008] In conjunction with the first aspect, in one implementation of the first aspect, before the first device receives the first information sent by the second device, the method further includes: receiving a second activation message sent by the second device, the second activation message being used to activate the target configuration in the first configuration information; and the first device sending the CSI report to the second device according to the target configuration.

[0117] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0118] The technical solutions of this application embodiment can be applied to various communication systems, such as: Global System for Mobile Communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD) system, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, 5th Generation (5G) system, or New Radio (NR), etc.

[0119] In this application, the terminal device can refer to user equipment, access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device. The terminal device can also be a cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, terminal device in 5G networks and future communication networks, or terminal device in a future evolved public land mobile network (PLMN), etc. This application does not limit the scope of the terminal device to these categories. Terminal devices can be mobile phones, tablets, computers with wireless transceiver capabilities, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, etc., and this application does not limit them.

[0120] The network device in this application embodiment can be a device for communicating with terminal devices. The network device can be a base station (BTS) in a global system of mobile communication (GSM) or code division multiple access (CDMA) system, a base station (nodeB, NB) in a wideband code division multiple access (WCDMA) system, an evolved NodeB (eNB or eNodeB) in an LTE system, a Next Generation NodeB (gNB or gNodeB) in a 5th generation (5G) system or new radio (NR) system, a radio controller in a cloud radio access network (CRAN) scenario, or a relay station, access point, vehicle-mounted device, wearable device, 5G network, or network device in a future communication network or a future evolved PLMN network, etc. The embodiments of this application are not limited.

[0121] Figure 1 This is a schematic diagram of a communication system to which the communication method provided in the embodiments of this application can be applied. Figure 1 As shown, the communication system may include network device 110 and terminal device 120.

[0122] Network device 110 and terminal device 120 can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on airplanes, balloons, and satellites. The embodiments of this application do not limit the application scenarios of the network device and terminal device.

[0123] It should be understood that the terminal device 120 can be one or more, and this application embodiment does not limit this.

[0124] Terminal device 120 can communicate with network device 120 wirelessly.

[0125] For example, terminal device 120 uses an encoder to encode channel state information (CSI) and then sends it to network device 110.

[0126] With the development of AI technology, AI modules may replace some traditional functional modules in wireless communication systems. Since AI technology is data-driven, its performance is closely related to the data. Therefore, when the characteristics of the data differ significantly from those of the AI's training data, or when the data is not distributed in the same way as the training data, the performance of the AI ​​module may be poor. Therefore, after introducing an AI module into a wireless communication system, it is necessary to monitor its performance.

[0127] For example, when a terminal device sends a CSI to a network device, an AI-based encoder (AI encoder) can be used instead of a codebook-based encoder (codebook encoder). That is, the terminal device uses the AI ​​encoder to encode the CSI and then sends it back to the network device. The network device then uses the corresponding AI-based decoder (AI decoder) to decode the CSI. During this process, it is necessary to monitor the performance of the AI ​​encoder and decoder.

[0128] One approach to monitoring the performance of an AI encoder is for the terminal device to send the raw CSI (or high-fidelity CSI) to the network device. The network device then compares the decoded CSI obtained using the AI ​​decoder with the raw CSI, allowing for performance evaluation of the AI ​​encoder and decoder. However, the terminal device encodes the CSI before transmitting it to the network device to reduce overhead. Sending the raw CSI simultaneously, while still allowing performance monitoring of the AI ​​module, significantly increases overhead.

[0129] Another approach is for the network device to send the AI ​​decoder to the terminal device, which then decodes the CSI encoded by the AI ​​encoder, thereby monitoring the performance of the AI ​​encoder and decoder. However, AI decoding is generally quite complex, and using the AI ​​decoder to decode the CSI on the terminal device would introduce additional computational complexity and power consumption.

[0130] In view of this, embodiments of this application provide a communication method and a communication device, with the aim of monitoring the performance of AI modules in a wireless communication system with less overhead.

[0131] The following will combine Figures 2 to 11 The communication methods and communication devices provided in the embodiments of this application are described in detail.

[0132] Figure 2 This is a schematic interaction diagram illustrating a communication method provided in an embodiment of this application. For example... Figure 2 As shown, the communication method 200 may include steps 210-220.

[0133] 210. The second device sends first configuration information to the first device, which instructs the first device to use a combination of the first mode and the second mode to send Channel State Information (CSI) reports. Correspondingly, the first device receives the first configuration information sent by the second device.

[0134] For example, the first configuration information instructs the first device to alternately use a first mode and a second mode to send CSI reports. For instance, the first device first uses the first mode to send CSI reports, then uses the second mode, then uses the first mode again, and so on in a cyclical manner. Alternatively, the first configuration information instructs the first device to use the first mode and the second mode to send CSI reports in a certain proportion. For instance, the first device uses the first mode to send CSI reports 20% of the time and uses the second mode 80% of the time.

[0135] For example, the first configuration information can be carried in a radio resource control (RRC) message, that is, the second device can send the first configuration information to the first device through an RRC message.

[0136] The first mode can be an AI-based CSI report feedback mode, and the second mode can be a codebook-based CSI report feedback mode. It should be understood that the first or second mode can also be other modes capable of providing CSI report feedback.

[0137] It should be understood that the second device in the embodiments of this application can Figure 1 The network devices shown, the first device can be Figure 1 The terminal devices shown can be one or more.

[0138] 220. The second device sends first information to the first device based on a first communication performance and a second communication performance. This first information instructs the first device to adjust the proportion of CSI reports sent using a first mode and / or the proportion of CSI reports sent using a second mode. The first communication performance refers to the communication performance of the second device communicating with the first device based on CSI reports sent by the first device in the first mode, and the second communication performance refers to the communication performance of the second device communicating with the first device based on CSI reports sent by the first device in the second mode. Correspondingly, the first device receives the first information sent by the second device.

[0139] It should be understood that the first communication performance refers to the communication performance of the second device communicating with the first device based on the CSI report sent by the first device in the first mode, i.e., the downlink communication performance in the first mode.

[0140] Specifically, the second device sends first configuration information to the first device, and the first device sends a CSI report to the second device in a first mode based on the first configuration information. At this time, the communication performance of the second device communicating with the first device based on the CSI report is the first communication performance.

[0141] Similarly, the second device sends first configuration information to the first device, and the first device sends a CSI report to the second device in the second mode based on the first configuration information. At this time, the communication performance of the second device communicating with the first device based on the CSI report is the second communication performance, that is, the downlink communication performance in the second mode.

[0142] It should be understood that the first and second communication performance can be evaluated by a second device (e.g., a network device) or by a first device (e.g., a terminal device).

[0143] When the first communication performance is evaluated by the first device, before the second device sends the first information to the first device based on the first and second communication performance, the method further includes:

[0144] The first device sends second information to the second device, and the second device receives the second information sent by the first device. The second information includes the first communication performance and the second communication performance, or the second information includes a comparison result of the first communication performance and the second communication performance.

[0145] It can be understood that when the second information includes the comparison result of the first communication performance and the second communication performance, in step 220, the second device sends the first information to the first device based on the first communication performance and the second communication performance. It can also be understood that the second device sends the first information to the first device based on the comparison result of the first communication performance and the second communication performance.

[0146] In other embodiments, the second information sent by the first device may also include an adjustment request, which requests an adjustment to the proportion of CSI reports sent by the first device using the first mode and / or the proportion of CSI reports sent using the second mode. In this case, the second device may send the first information to the first device based on the adjustment request.

[0147] Optionally, the first configuration information may also include one or more of the following: an evaluation instruction, used to instruct the first device to evaluate the first communication performance and the second communication performance; an evaluation index, used to instruct the first device to use the evaluation index to evaluate the first communication performance and the second communication performance; and an evaluation duration, used to instruct the first device to evaluate the first communication performance and the second communication performance for the duration.

[0148] In one possible implementation, the second device sends first information to the first device based on the first communication performance and the second communication performance, the first information being used to instruct the first device to adjust the proportion of CSI reports sent using the first mode.

[0149] In another possible implementation, the second device sends first information to the first device based on the first communication performance and the second communication performance, the first information being used to instruct the first device to adjust the proportion of CSI reports sent using the second mode.

[0150] In another possible implementation, the second device sends first information to the first device based on the first communication performance and the second communication performance. The first information is used to instruct the first device to adjust the proportion of sending CSI reports using the first mode and the proportion of sending CSI reports using the second mode.

[0151] In some embodiments, if the first communication performance is higher than the second communication performance, the first information instructs the first device to increase the proportion of the first mode (i.e., the proportion of the first device using the first mode to send CSI reports) and decrease the proportion of the second mode (i.e., the proportion of the first device using the second mode to send CSI reports).

[0152] If the first communication performance is lower than the second communication performance, the first information instructs the first device to reduce the proportion of the first mode and increase the proportion of the second mode.

[0153] Optionally, before the second device sends the first information to the first device based on the first communication performance and the second communication performance, the method further includes step 230.

[0154] 230. The first device sends a CSI report to the second device based on the first configuration information.

[0155] For example, the first device may send a CSI report in a first mode and a second mode based on the first configuration information.

[0156] Optionally, before the second device sends the first information to the first device based on the first communication performance and the second communication performance, the method further includes:

[0157] The second device sends a second activation message to the first device, which is used to activate the target configuration in the first configuration information.

[0158] It should be understood that the second activation message can be a medium access control element (MAC CE) message or a downlink control information (DCI) message.

[0159] It is understood that the process of the second device sending the second activation message to the first device can take place before step 230. Accordingly, the first device receives the second activation message and can send a CSI report to the second device according to the target configuration activated by the second activation message.

[0160] In this embodiment of the application, the first configuration information includes at least one ratio set list, the at least one ratio set list

[0161] Each list of scale sets contains at least one scale set, and each scale set gives a set of possible values ​​for N and possible values ​​for K.

[0162] Values ​​or possible distribution indication information, where N is the number of CSI reports sent by the first device, and K is the number of CSI reports sent by the first device.

[0163] The number of CSI reports sent in the first mode, where N is a positive integer and K is an integer greater than or equal to 0 and less than or equal to N. The distribution indication information is used to indicate the distribution of CSI reports sent by the first device in the first mode and / or the distribution of CSI reports sent by the first device in the second mode.

[0164] It should be understood that this distribution indication information can indicate the positional distribution of K CSI reports in the first mode among N CSI reports, or it can indicate the distribution of NK CSI reports in the second mode among N CSI reports, or it can indicate the distribution of CSI reports in the first mode and CSI reports in the second mode among N CSI reports. Alternatively, this distribution indication information can indicate a distribution pattern in which the CSI reports in the first mode and CSI reports in the second mode have a corresponding distribution among N CSI reports. For example, the distribution indication information is a bitmap.

[0165] All possible N and K values ​​and their distribution indication information configured by the second device for the first device are described by the at least one scale set list. Activating the target configuration in the first configuration information includes enabling one scale set in one of the scale set lists, corresponding to a set of N and K values ​​and their distribution indication information.

[0166] It should be understood that this list of proportions can also be called a list of ratios, a list of values, etc.

[0167] Optionally, the first configuration information can be used to indicate the first CSI report configuration used by the first device to send CSI reports. The first CSI report configuration is used to instruct the first device to send N CSI reports to the second device, where N is a positive integer. Under the first CSI report configuration, the number of CSI reports sent by the first device in the first mode is K, and the number of CSI reports sent by the first device in the second mode is NK, where K is an integer greater than or equal to 0 and less than or equal to N.

[0168] Specifically, the first CSI report configuration can be used to instruct the first device to operate in a hybrid mode of the first mode and the second mode when sending N CSI reports to the second device. The hybrid mode refers to the first device sending CSI reports to the second device based partly on the first mode and partly on the second mode. The proportion and distribution of the first mode and the second mode can be determined by the above-mentioned N, K and their distribution indication information.

[0169] In this technical solution, N, K, and their distribution indication information are all included in the aforementioned ratio set list. In another possible implementation, N is determined by the first CSI report configuration, while the possible values ​​of K and their distribution indication information are included in the aforementioned ratio set list; or, K is determined by the first CSI report configuration, while the possible values ​​of N and their distribution indication information are included in the aforementioned ratio set list. In a third possible implementation, one or more of N, K, or their distribution indication information are agreed upon in advance by the first and second devices, and other information is included in the aforementioned ratio set list. In a fourth possible implementation, the first CSI report configuration includes a set of N, K, and their distribution indication information, while more possible values ​​of N, possible values ​​of K, or distribution indication information are included in the aforementioned ratio set list. A further possible implementation is a combination of the above four implementations. All implementations should ensure that the first and second devices, operating in the aforementioned hybrid mode, have a known set of N, K, and their distribution indication information before starting to send CSI reports.

[0170] Optionally, the list of proportion sets can be included in the first CSI report configuration described above.

[0171] For example, see Figure 3 , Figure 3 This is a schematic diagram illustrating a CSI report configuration provided in an embodiment of this application. For example... Figure 3 As shown, the first CSI report configuration is used to instruct the first device to send N CSI reports to the second device after acquiring CSI based on the measurement of the CSI reference signal (CSI-RS). Of these N CSI reports, the number of CSI reports sent by the first device in the first mode is K, and the number of CSI reports sent by the first device in the second mode is NK.

[0172] For example, if N is 5 and K is 1, then the first device sends 1 CSI report in the first mode and 4 CSI reports in the second mode. In this case, the first CSI report is configured to instruct the first device to send 5 CSI reports to the second device.

[0173] In some embodiments, the first CSI report configuration is further configured to instruct the first device to periodically send multiple sets of N CSI reports.

[0174] In this technical solution, the first device periodically sends CSI reports. The periodic CSI report configuration takes effect immediately after being set. The first device periodically sends CSI reports to the second device using a set of N CSI reports as the basic cycle unit, and continues sending reports until a new configuration message is received. During this process, the first CSI report configuration should include a set of values ​​for N and K, or their distribution indication information. Other possible values ​​for N and K, or their distribution indication information, are included in the aforementioned ratio set list. While the first device is sending CSI reports, the second device can activate another ratio set in the ratio set list via a MAC CE message or a DCI message. This other ratio set corresponds to another set of values ​​for N and K, or their distribution indication information, thereby changing the ratio and / or distribution of the first mode and / or the second mode in the N CSI reports sent by the first device.

[0175] Optionally, the first CSI report configuration is also used to instruct the first device to semi-continuously send multiple sets of N CSI reports.

[0176] In this technical solution, the first device semi-persistently sends CSI reports. After configuring the semi-persistent CSI reporting, it needs to activate or trigger CSI reporting via a MACCE or DCI message. Simultaneously with activating or triggering CSI reporting via a MACCE or DCI message, one of the ratio sets in the aforementioned ratio set list can be activated to obtain a set of values ​​for N, K, or their distribution indication information. Then, the first device uses a set of N CSI reports as the basic loop unit and continuously and periodically sends CSI reports to the second device using the obtained N, K, and their distribution indication information until a new message is received to terminate CSI report sending or modify the CSI report configuration. During the process of the first device sending CSI reports, the second device can activate another ratio set in the aforementioned ratio set list via a MACCE or DCI message. This other ratio set corresponds to another set of values ​​for N, K, or their distribution indication information, thereby changing the ratio and / or distribution of the first mode and / or the second mode in the N CSI reports sent by the first device.

[0177] Optionally, the first CSI report configuration is also used to instruct the first device to send CSI reports non-periodically.

[0178] In this technical solution, the first device sends CSI reports non-periodically. That is, after configuring the non-periodic CSI reporting using the aforementioned first CSI report configuration information, it needs to activate or trigger CSI reporting via a MACCE message or DCI message. Simultaneously with activating or triggering CSI reporting via the MACCE message or DCI message, one of the aforementioned proportion sets in the proportion set list can be activated, specifying the values ​​of N, K, or their distribution indication information. Then, the first device sends at least one set of N CSI reports to the second device according to the aforementioned first CSI report configuration, and automatically stops after sending is complete.

[0179] In the above embodiments, the CSI report can be carried on the physical uplink control channel (PUCCH) or the physical uplink shared channel (PUSCH).

[0180] It should be understood that, for each of the N CSI reports in the aforementioned multiple groups of N CSI reports, before the configuration is changed, the number of CSI reports sent by the first device in the first mode is the same, the distribution of the first mode is also the same, the number of CSI reports sent by the first device in the second mode is the same, and the distribution of the second mode is also the same.

[0181] Optionally, the first configuration information is used to indicate the first CSI report group configuration used by the first device to send CSI reports. The first CSI report group configuration contains N second CSI report configurations, where N is a positive integer. Each second CSI report configuration is used to indicate one CSI report of the first device. The number of CSI reports sent by the first device in the first mode is K, and the number of CSI reports sent by the first device in the second mode is NK, where K is an integer greater than or equal to 0 and less than or equal to N.

[0182] In this technical solution, the possible values ​​of N, the possible values ​​of K, and their distribution indication information are all included in the aforementioned ratio set list. In another possible implementation, N is determined by the configuration of the first CSI report group, while the possible values ​​of K and their distribution indication information are included in the aforementioned ratio set list; or, K is determined by the configuration of the first CSI report group, while the possible values ​​of N and their distribution indication information are included in the aforementioned ratio set list. In a third possible implementation, one or more of N, K, or their distribution indication information are agreed upon in advance by the first and second devices, and other information is included in the aforementioned ratio set list. In a fourth possible implementation, the first CSI report group configuration includes a set of N, K, and their distribution indication information, while more possible values ​​of N, possible values ​​of K, or their distribution indication information are included in the aforementioned ratio set list. A further possible implementation is a combination of the above four implementations. All implementations should ensure that the first and second devices, operating in the aforementioned hybrid mode, have a known set of N, K, and their distribution indication information before starting to send CSI reports.

[0183] Optionally, the list of proportion sets can be included in the first CSI report group configuration described above. For example, see... Figure 4 , Figure 4 This is a schematic diagram illustrating a CSI report group configuration provided in an embodiment of this application. For example... Figure 4 As shown, the first configuration information is used to indicate a first CSI report group configuration, which in turn indicates N second CSI report configurations. Each second CSI report configuration instructs the first device to send a CSI report to the second device after acquiring CSI based on CSI-RS measurements. Among the N second CSI report configurations and the corresponding N CSI reports, the number of CSI reports sent by the first device in the first mode is K, and the number of CSI reports sent by the first device in the second mode is NK.

[0184] For example, if N is 5 and K is 1, then the first device sends 1 CSI report in the first mode and 4 CSI reports in the second mode. The first CSI report group configuration includes 5 second CSI report configurations, which are used to instruct the first device to send 5 CSI reports to the second device.

[0185] In some embodiments, the first CSI report group configuration or the second CSI report configuration is also used to instruct the first device to periodically send CSI reports.

[0186] Optionally, the first CSI report group configuration or the second CSI report configuration is also used to instruct the first device to semi-persistently send CSI reports.

[0187] Optionally, the first CSI report group configuration or the second CSI report configuration is also used to instruct the first device to send CSI reports non-periodically.

[0188] The descriptions regarding the configuration of the first CSI report group or the second CSI report that instruct the first device to periodically send CSI reports, or instruct the first device to semi-continuously send CSI reports, or instruct the first device to non-periodicly send CSI reports can be found in the above embodiments regarding the description of the first CSI report configuration instructing the first device to send CSI reports, and will not be repeated here.

[0189] Optionally, the first configuration information is used to indicate the second CSI report group configuration used by the first device to send CSI reports. The second CSI report group configuration includes two third CSI report configurations. One of the two third CSI report configurations is used to indicate that the first device sends CSI reports using a first mode, and the other of the two third CSI report configurations is used to indicate that the first device sends CSI reports using a second mode.

[0190] For example, see Figure 5 , Figure 5 This is a schematic diagram of another CSI report group configuration provided in an embodiment of this application. For example... Figure 5 As shown, the first configuration information can be used to instruct the second CSI report group configuration, which can be used to instruct CSI report configuration one and CSI report configuration two. CSI report configuration two is used to instruct the first device to send CSI reports using a first mode, and CSI report configuration one is used to instruct the first device to send CSI reports using a second mode.

[0191] In one example, when the first device sends CSI reports according to both CSI report configuration one and CSI report configuration two, the two CSI reports may overlap. The first device needs to obtain CSI reports using both modes based on the same CSI-RS. In this case, the first device can send both CSI reports to the second device, or it can choose one to send to the second device. One possible selection criterion is to compare the channel quality indicator (CQI) values ​​obtained from the two CSI reports and send the CSI report with the higher CQI value to the second device.

[0192] In some embodiments, the period for the first device to send CSI reports using the first mode is N*T / K, and the period for the first device to send CSI reports using the second mode is T, where N is a positive integer and K is a natural number. When K equals 0, the first device does not use the first mode to send CSI reports.

[0193] In this technical solution, the possible values ​​of N, the possible values ​​of K, and their distribution indication information are all included in the aforementioned ratio set list. In another possible implementation, N is determined by the configuration of the second CSI report group, while the possible values ​​of K and their distribution indication information are included in the aforementioned ratio set list; or, K is determined by the configuration of the second CSI report group, while the possible values ​​of N and their distribution indication information are included in the aforementioned ratio set list. In a third possible implementation, one or more of N, K, or their distribution indication information are agreed upon in advance by the first and second devices, and other information is included in the aforementioned ratio set list. In a fourth possible implementation, the second CSI report group configuration includes a set of N, K, and their distribution indication information, while more possible values ​​of N, possible values ​​of K, or their distribution indication information are included in the aforementioned ratio set list. A further possible implementation is a combination of the above four implementations. All implementations should ensure that the first and second devices, operating in the aforementioned hybrid mode, have a known set of N, K, and their distribution indication information before starting to send CSI reports.

[0194] Optionally, the list of proportion sets can be included in the second CSI report group configuration described above.

[0195] In this embodiment, when K is 0, the first device does not use the first mode to send CSI reports, meaning that all CSI reports sent by the first device are sent in the second mode. For example, the first device only uses the codebook-based CSI feedback mode and does not use the AI-based CSI feedback mode.

[0196] In some embodiments, the second CSI report group configuration or the third CSI report configuration is also used to instruct the first device to periodically send CSI reports.

[0197] Optionally, the second CSI report group configuration or the third CSI report configuration is also used to instruct the first device to semi-persistently send CSI reports.

[0198] Optionally, the second CSI report group configuration or the third CSI report configuration is also used to instruct the first device to send CSI reports non-periodically.

[0199] The descriptions regarding the second CSI report group configuration or the third CSI report configuration instructing the first device to periodically send CSI reports, or instructing the first device to semi-continuously send CSI reports, or instructing the first device to non-periodicly send CSI reports, can be found in the above embodiments regarding the description of the first CSI report configuration instructing the first device to send CSI reports. For the sake of brevity, these descriptions will not be repeated here.

[0200] The following will combine Figure 6 This application introduces the technical solution for configuring CSI reports using first configuration information in its embodiments. Figure 6 This is a schematic diagram of an activation ratio set provided in an embodiment of this application.

[0201] Option 1, such as Figure 6 As shown in (a), the first configuration message includes at least: a trigger state list (TriggerStateList), at least one CSI report configuration table (CSI-ReportConfig), and at least one ratio set list (RatioSetList). A set of contents in the trigger state list contains a CSI report configuration number (or CSI report configuration index) and a ratio set sequence number; each CSI report configuration table in the at least one CSI report configuration table contains a CSI report configuration number and a ratio set list number. A set of contents in the trigger state list is associated with a CSI report configuration table via the CSI report configuration number, and the CSI report configuration table is associated with a ratio set list via the ratio set list number. That is, based on a set of contents in the trigger state list, a CSI report configuration table can be located via the CSI report configuration number, and a corresponding ratio set list can be located via the ratio set list number in the CSI report configuration table. Furthermore, a specific ratio set can be located via the ratio set list and the ratio set sequence number in the set of contents in the trigger state list.

[0202] Optionally, the list of proportion sets can also be included in its corresponding CSI report configuration table. That is, after locating the CSI report configuration table, the list of proportion sets in the CSI report configuration table can be obtained. In this case, the first configuration message contains at least two lists or tables: a trigger status list and at least one CSI report configuration table.

[0203] Optionally, the list of at least one scale set can also be agreed upon in advance, for example, through standardization, so that the first and second devices can know it beforehand. Other processes are similar and will not be described in detail here.

[0204] Option 2, such as Figure 6 As shown in (b), the first configuration message includes at least: a trigger status list and at least one CSI report configuration table. A set of contents in the trigger status list contains a CSI report configuration number; each of the at least one CSI report configuration table contains a CSI report configuration number and a list of proportion sets. A set of contents in the trigger status list is associated with a CSI report configuration table via the CSI report configuration number; that is, based on a set of contents in the trigger status list, a CSI report configuration table can be located via the CSI report configuration number, and thus the list of proportion sets within it can be obtained.

[0205] Optionally, the scale set list can exist independently instead of being included in the CSI report configuration table. In this case, the first configuration message contains at least three lists or tables: a trigger status list, at least one CSI report configuration table, and at least one scale set list. Each CSI report configuration table contains a CSI report configuration number and a scale set list number. A CSI report configuration table can be associated with a scale set list through the scale set list number. That is, based on a set of contents in the trigger status list, a CSI report configuration table can be located through the CSI report configuration number, and a corresponding scale set list can be located through the scale set list number in that CSI report configuration table.

[0206] Optionally, this ratio set can also be agreed upon in advance, for example, through standardization, so that the first and second devices can know it beforehand. Other processes are similar and will not be described in detail here.

[0207] Optionally, the first configuration information is further used to indicate a list of scale sets, each scale set in the list including a set of scale configuration information, the scale configuration information including one or more of the following: N, K, distribution indication information, wherein the distribution indication information is used to indicate the distribution of the first mode and the second mode.

[0208] For example, the proportion configuration information includes K, while N and / or distribution indication information are carried in the configuration information.

[0209] For example, the proportional configuration information includes N, while K and / or distribution indication information are carried in the configuration information.

[0210] Optionally, when the proportional configuration information includes one or two of N, K, and distribution indication information, the other information should be indicated by other messages or agreed upon in advance.

[0211] For example, the ratio configuration information includes N and K, while the distribution indication information can be predefined, for example, the distribution indication information is predetermined by the first device and the second device.

[0212] For example, if the ratio configuration information includes K and distribution indication information, then N can be predefined or indicated by other information.

[0213] Optionally, the first information is a first activation message, which is used to activate a proportion set in the proportion set list, and N, K, and distribution indication information are used to implement a first CSI report configuration; or, N, K, and distribution indication information are used to implement a first CSI report group configuration; or, N, K, and distribution indication information are used to implement a second CSI report group configuration. The first activation message can be a MAC CE message or a DCI message.

[0214] For example, the first device originally sends CSI reports using the configuration in ratio set 1 according to the configuration information of the second device. The second device sends the DCI message to the first device according to the first communication performance and the second communication performance. The DCI message instructs the first device to send CSI reports according to the configuration in ratio set 2. For example, the N, K and distribution indication information in ratio set 2 are used to implement the first CSI report configuration, the first CSI report group configuration, or the second CSI report group configuration described above.

[0215] In one possible implementation, after receiving the first information, the first device adjusts the proportion of sending CSI reports using the first mode and / or the proportion of sending CSI reports using the second mode based on the first information.

[0216] Optionally, such as Figure 2 As shown, the method may further include step 240.

[0217] 240. Based on the first information, the first device adjusts the proportion of CSI reports sent using the first mode and / or the proportion of CSI reports sent using the second mode.

[0218] For example, the first device increases the proportion of CSI reports sent using the first mode and decreases the proportion of CSI reports sent using the second mode based on the first information.

[0219] For example, the first device reduces the proportion of CSI reports sent using the first mode and increases the proportion of CSI reports sent using the second mode based on the first information.

[0220] In some embodiments, if the first communication performance is higher than the second communication performance, the first device can increase the proportion of the first mode and decrease the proportion of the second mode based on the first information.

[0221] If the first communication performance is lower than the second communication performance, the first device can reduce the proportion of the first mode and increase the proportion of the second mode based on the first information.

[0222] The first device may adjust the proportion of CSI reports sent using the first mode and / or the proportion of CSI reports sent using the second mode based on the first information in the following ways:

[0223] Method 1:

[0224] In some embodiments, the first device adjusts the proportion of CSI reports sent using a first mode and / or the proportion of CSI reports sent using a second mode based on first information, including the following steps:

[0225] The CSI report configuration number and proportion set number in the trigger status list are determined by the first activation message;

[0226] The CSI report configuration form is determined by the CSI report configuration number;

[0227] Determine the list of proportion sets using the CSI report configuration table;

[0228] A scale set in the scale set list is determined and activated using the scale set list and scale set number.

[0229] For example, see Figure 6 In (a) of the above, the first configuration information may include a trigger status list, at least one ratio set list, at least one CSI report configuration table, etc. The trigger status list may include multiple sets of CSI report configuration numbers (CSI-reportconfigID) and ratio set serial numbers; each ratio set list in the at least one ratio set list may include multiple ratio sets, wherein each ratio set may include a set of N, K and distribution indication information; each CSI report configuration table in the at least one CSI report configuration table may include a CSI report configuration number and a ratio set list number, etc.

[0230] It should be understood that this set of proportions may also include one or more of N, K, and distribution indication information, as described above, and will not be repeated here.

[0231] The first activation message can be a DCI message, which may contain a CSI request. The CSI request's value is associated with a group in the corresponding trigger status list. The first device can locate a CSI report configuration table using the CSI report configuration number in that group. It can then locate a corresponding ratio set list using the ratio set list number in the CSI report configuration table. Furthermore, by using the ratio set list and the ratio set sequence number in that group in the trigger status list, it can locate a specific ratio set within that ratio set list, such as the M2 ratio set. In this embodiment, activating a ratio set means enabling the values ​​of N and K in that ratio set and their distribution, so that the first device can send a CSI report based on N, K, and their distribution.

[0232] It should be understood that in some embodiments, the first activation message may also be a MAC CE message, and the process of activating the proportion set can be referred to the description above, which will not be repeated for the sake of brevity.

[0233] In some embodiments, when the first activation message is a MAC CE message, the MAC CE message may also directly carry a set of N, K, and distribution indication information, so that the first device can send a CSI report based on the N, K, and distribution indication information after receiving the MAC CE message. This technical solution allows the first device to make rapid adjustments, improving the efficiency of adjusting the transmission of CSI reports using different modes. It should be understood that the MAC CE message may also carry only one or more of the N, K, and distribution indication information, with other information using pre-agreed or currently used configurations.

[0234] Method 2:

[0235] In other embodiments, the first device adjusts the proportion of CSI reports sent using a first mode and / or the proportion of CSI reports sent using a second mode based on the first information, including the following steps:

[0236] The CSI report configuration number in the trigger status list is determined by the first activation message;

[0237] The CSI report configuration form is determined by the CSI report configuration number;

[0238] Determine the list of proportion sets using the CSI report configuration table;

[0239] A scale set in the scale set list is determined and activated using the scale set sequence number in the first activation message.

[0240] For example, see Figure 6 In (b) of the first configuration information, the trigger status list and at least one CSI report configuration table may be included. The trigger status list may include multiple sets of CSI report configuration numbers; each of the at least one CSI report configuration table may include a CSI report configuration number and a list of proportion sets, etc.

[0241] The first activation message can be a DCI message, which may contain a CSI request. The value of this request is associated with a group in the corresponding trigger status list. The first device can locate a CSI report configuration table using the CSI report configuration number in that group of trigger statuses. This CSI report configuration table contains a list of proportion sets. Furthermore, by using this list of proportion sets and the proportion set sequence number contained in the DCI message, a specific proportion set can be located within that list. In this embodiment, activating a proportion set means enabling the values ​​of N and K in that proportion set, as well as their distribution. Thus, the first device can send a CSI report based on N, K, and their distribution.

[0242] It should be understood that this set of proportions may also include one or more of N, K, and distribution indication information, as described above, and will not be repeated here.

[0243] It should be understood that this proportion set number is new information added to the DCI message and can be obtained by modifying the DCI message.

[0244] In Method 1 above, if the list of proportion sets is included in the corresponding CSI report configuration table, or in Method 2 above, if the list of proportion sets exists independently instead of being included in the corresponding CSI report configuration table, Method 1 and Method 2 can be used interchangeably to achieve the action of activating a set of proportion sets through DCI messages, which will not be elaborated here.

[0245] It should be understood that in some embodiments, the first activation message may also be a MAC CE message, and the process of activating the proportion set can be referred to the description above, which will not be repeated for the sake of brevity.

[0246] In some embodiments, when the first activation message is a MAC CE message, the MAC CE message may also directly carry a set of N, K, and distribution indication information. Therefore, the first device can send a CSI report based on the N, K, and distribution indication information after receiving the MAC CE message. This technical solution allows the first device to make rapid adjustments, improving the efficiency of adjusting the sending of CSI reports using different modes. It should be understood that the MAC CE message may also carry only one or more of the N, K, and distribution indication information, with other information using pre-agreed or currently used configurations.

[0247] Method 3:

[0248] In other embodiments, the first information may also be second configuration information and a second activation message.

[0249] It should be understood that in this case, the second configuration information and the second activation message are sent separately, that is, the second device first sends the second configuration information to the first device, and then sends the second activation message to the first device, thereby activating a ratio set in the second configuration information.

[0250] For example, the second configuration information may include different configuration schemes in the first configuration information. For instance, if the second device updates the configuration information, the second device may send the second configuration information to the first device and then send the second activation message. The first device can then determine a proportion set in the second configuration information based on the second activation message, and thus send a CSI report based on the obtained N, K and distribution indication information.

[0251] It should be understood that the specific process by which the first device determines the proportion set based on the second activation message can be found in the previous description of the first device determining the proportion set based on the first activation message, and will not be repeated here for the sake of brevity.

[0252] Based on the embodiments of this application, the second device sends configuration information to the first device. The first device can then use a combination of a first mode and a second mode to send CSI reports according to the configuration information sent by the second device. The second device can also send first information to the first device based on first and second communication performance to instruct the first device to adjust the proportion of CSI report sending using the first mode and / or the second mode according to the first information. This technical solution can monitor the performance of the first device in sending CSI reports in the first and second modes with relatively low overhead. Furthermore, it can adjust the first device's use of the first mode and the second mode to send CSI reports in a timely manner.

[0253] Figure 7 This is a schematic interaction diagram illustrating a communication method provided in an embodiment of this application. Taking the interaction between a network device and a terminal device as an example, such as... Figure 7 As shown, the method 300 may include steps 310 to 340.

[0254] 310. The network device sends first configuration information to the terminal device. The first configuration information is used to instruct the terminal device to send CSI reports using a combination of first mode and second mode.

[0255] It should be understood that step 310 can be referred to in the relevant description of step 210, and for the sake of brevity, it will not be repeated.

[0256] 320. The terminal device sends a CSI report to the network device based on the first configuration information.

[0257] 330. Network equipment is evaluated for first and second communication performance.

[0258] The first communication performance refers to the communication performance of the network device communicating with the terminal device based on the CSI report sent by the terminal device in the first mode, and the second communication performance refers to the communication performance of the network device communicating with the terminal device based on the CSI report sent by the terminal device in the second mode.

[0259] It should be understood that the first and second communication performance refer to downlink communication performance, i.e., the performance of network devices communicating with terminal devices. For example, network devices can evaluate the first and second communication performance using evaluation metrics. These evaluation metrics can be system throughput, ACK or NACK ratio, CQI value, etc.

[0260] For example, during the evaluation period, the network device calculates the CQI value based on the CSI reports sent by the terminal device in two modes, or performs downlink communication based on the CSI reports sent by the terminal device in two modes. During this process, it statistically analyzes (or calculates) the downlink communication throughput in both modes, or the proportion of acknowledgment (ACK) or negative acknowledgment (NACK) signals fed back by the terminal device to the network device for downlink communication. It is understood that higher CQI values, higher communication throughput, and higher ACK ratios (or lower NACK ratios) indicate better communication performance.

[0261] 340. The network device sends first information to the terminal device based on the first communication performance and the second communication performance.

[0262] The first information is used to instruct the terminal device to adjust the proportion of CSI reports sent using the first mode and / or the proportion of CSI reports sent using the second mode. One possible implementation is to activate another set of proportions using DCI messages or MAC CE messages.

[0263] In one example, the network device evaluates the first communication performance and the second communication performance based on system throughput. If the first communication performance is higher than the second communication performance, the first information can instruct the terminal device to increase the proportion of CSI reports sent using the first mode and decrease the proportion of CSI reports sent using the second mode. One possible implementation is that the first information includes DCI (Distributed Communication Interface) to activate another set of proportions where the proportion of CSI reports sent using the first mode is higher.

[0264] It should be understood that when comparing the first communication performance and the second communication performance, a threshold can be added to the communication performance. For example, when the difference between the two is greater than or equal to the threshold, the first communication performance can be considered to be higher than the second communication performance.

[0265] In another example, the network device evaluates the first communication performance and the second communication performance by the system throughput. If the first communication performance is lower than the second communication performance, the first information can instruct the terminal device to reduce the proportion of CSI reports sent using the first mode and increase the proportion of CSI reports sent using the second mode.

[0266] Optionally, the method 300 may further include step 350.

[0267] 350. The terminal device adjusts the proportion of CSI reports sent using the first mode and / or the proportion of CSI reports sent using the second mode based on the first information.

[0268] For example, if the first information instructs the terminal device to increase the proportion of sending CSI reports using the first mode and decrease the proportion of sending CSI reports using the second mode, the terminal device can increase the proportion of sending CSI reports using the first mode and decrease the proportion of sending CSI reports using the second mode according to the first information.

[0269] Optionally, prior to step 320, the method may further include:

[0270] The network device sends a second activation message to the terminal device, which is used to activate the target configuration in the first configuration information.

[0271] In some embodiments, the terminal device sends a CSI report to the network device based on first configuration information, including:

[0272] The terminal device sends a CSI report to the network device according to the target configuration.

[0273] For example, the target configuration may include a set of N, K and distribution indication information, which the terminal device can use to send a CSI report to the network device.

[0274] Optionally, the first configuration information is used to indicate the first CSI report configuration used by the terminal device to send CSI reports. The first CSI report configuration is used to instruct the terminal device to send N CSI reports to the network device, where N is a positive integer. In the first mode, the number of CSI reports sent by the terminal device is K, and in the second mode, the number of CSI reports sent by the terminal device is NK, where K is an integer greater than or equal to 0 and less than or equal to N.

[0275] In some embodiments, the first CSI report configuration is further configured to instruct the terminal device to send multiple sets of N CSI reports.

[0276] For example, the configuration of this first CSI report can be found in the previous section on... Figure 3 For the sake of brevity, the relevant descriptions will not be repeated.

[0277] Optionally, the first configuration information is used to indicate the first CSI report group configuration used by the terminal device to send CSI reports. The first CSI report group configuration contains N second CSI report configurations, where N is a positive integer. Each second CSI report configuration is used to indicate one CSI report of the terminal device. The number of CSI reports sent by the terminal device in the first mode is K, and the number of CSI reports sent by the terminal device in the second mode is NK, where K is an integer greater than or equal to 0 and less than or equal to N.

[0278] In some embodiments, each second CSI report is configured to instruct the terminal device to send multiple CSI reports.

[0279] For example, the configuration of this first CSI reporting group can be found in the previous section on... Figure 4 For the sake of brevity, the relevant descriptions will not be repeated.

[0280] Optionally, the first configuration information is used to indicate the second CSI report group configuration used by the terminal device to send CSI reports. The second CSI report group configuration includes two third CSI report configurations. One of the two third CSI report configurations is used to indicate the terminal device to send CSI reports using a first mode, and the other of the two third CSI report configurations is used to indicate the terminal device to send CSI reports using a second mode.

[0281] In some embodiments, the terminal device sends CSI reports using a first mode for a period of NT / K, and the terminal device sends CSI reports using a second mode for a period of T, where N is a positive integer and K is a natural number. When K equals 0, the terminal device does not send CSI reports using the first mode.

[0282] For example, the configuration of this second CSI reporting group can be found in the previous section on... Figure 5 For the sake of brevity, the relevant descriptions will not be repeated.

[0283] Optionally, the first configuration information is also used to indicate a list of scale sets, each scale set in the list of scale sets including a set of scale configuration information, the scale configuration information including one or more of the following: N, K, distribution indication information, wherein the distribution indication information is used to indicate the distribution of the first mode and the second mode.

[0284] Optionally, the first information is a first activation message, which is used to activate a proportion set in the proportion set list, and N, K, and distribution indication information are used to implement the first CSI report configuration; or,

[0285] N, K, and distribution indication information are used to configure the first CSI reporting group; or...

[0286] N, K, and distribution indication information are used to configure the second CSI reporting group.

[0287] It should be understood that, in this case, the technical solution for adjusting the proportion of CSI reports sent using the first mode and / or the proportion of CSI reports sent using the second mode based on the first information can be found in the preceding text regarding... Figure 6 The relevant descriptions of (a) and (b) in the text will not be repeated for the sake of brevity.

[0288] It should be understood that the first activation message can be a MAC CE message or a DCI message.

[0289] In some embodiments, when the first activation message is a MAC CE message, the MAC CE message may also directly carry a set of N, K, and distribution indication information. Therefore, after receiving the MAC CE message, the terminal device can send a CSI report based on the N, K, and distribution indication information. This technical solution allows the terminal device to make rapid adjustments, improving the efficiency of adjusting the transmission of CSI reports using different modes. It should be understood that the MAC CE message may also carry only one or more of the N, K, and distribution indication information, with other information using pre-agreed or currently used configurations.

[0290] In some embodiments, the target configuration mentioned above may include a scale set from a scale set list.

[0291] Optionally, the first configuration information can be carried in an RRC message.

[0292] The first mode in this application embodiment can be a CSI feedback mode based on artificial intelligence (AI); the second mode can be a CSI feedback mode based on codebook. It should be understood that the first mode and the second mode can also be other CSI feedback modes, which are not limited in this application embodiment.

[0293] Based on the embodiments of this application, a network device can configure a terminal device to operate in a hybrid mode of a first mode and a second mode. The terminal device sends a CSI report according to the configuration information of the network device. The network device evaluates the performance of the two communication modes and, based on the evaluated performance, sends information to the terminal device instructing it to adjust the ratio of sending CSI reports using the first mode and the second mode. This technical solution can effectively monitor the performance of the two modes with low overhead; furthermore, it can adjust the operating mode of the terminal device sending CSI reports in real time or near real time.

[0294] Figure 8 This is a schematic interaction diagram illustrating another communication method provided in an embodiment of this application. Taking the interaction between a network device and a terminal device as an example, such as... Figure 8 As shown, the method 400 may include steps 410 to 450.

[0295] 410. The network device sends first configuration information to the terminal device. The first configuration information is used to instruct the terminal device to send CSI reports using a combination of first mode and second mode.

[0296] It should be understood that step 310 can be referred to in the relevant description of step 210, and for the sake of brevity, it will not be repeated.

[0297] 420. The terminal device sends a CSI report to the network device based on the first configuration information.

[0298] The terminal device sends a CSI report to the network device using a first mode and a second mode based on the specific configuration information in the first configuration information.

[0299] 430. The terminal equipment evaluates the first and second communication performance.

[0300] The first communication performance refers to the communication performance of the network device communicating with the terminal device based on the CSI report sent by the terminal device in the first mode, and the second communication performance refers to the communication performance of the network device communicating with the terminal device based on the CSI report sent by the terminal device in the second mode.

[0301] It should be understood that the first and second communication performance refers to downlink communication performance. For example, the terminal device can evaluate the first and second communication performance using evaluation metrics. These evaluation metrics could be system throughput, ACK or NACK ratio, CQI value, etc.

[0302] For example, during the evaluation period, the terminal device calculates the system throughput, ACK / NACK ratio, or CQI value for communication between the network device and the terminal device based on the CSI reports sent by the terminal device in both modes. It can be understood that the higher the CQI value, the higher the communication throughput, and the higher the ACK ratio (or the lower the NACK ratio), the better the communication performance.

[0303] 440. The terminal device sends second information to the network device. The second information includes first communication performance and second communication performance, or the second information includes a comparison result of the first communication performance and the second communication performance.

[0304] In some embodiments, the second information may also be an adjustment request message, which is used to request an adjustment of the proportion of CSI reports sent by the terminal device using the first mode and / or the proportion of CSI reports sent using the second mode.

[0305] For example, if the first communication performance is higher than the second communication performance, the terminal device can use the adjustment request message to request an increase in the proportion of CSI reports sent using the first mode and a decrease in the proportion of CSI reports sent using the second mode.

[0306] In other embodiments, the second information may include both the first communication performance and the second communication performance, or a comparison result of the first communication performance and the second communication performance, and may also include the adjustment request message.

[0307] 450. The network device sends first information to the terminal device based on the first communication performance and the second communication performance.

[0308] The first information is used to instruct the terminal device to adjust the proportion of CSI reports sent using the first mode and / or the proportion of CSI reports sent using the second mode.

[0309] In one example, if a network device determines that a first communication performance is higher than a second communication performance, the first information can instruct the terminal device to increase the proportion of CSI reports sent using the first mode and decrease the proportion of CSI reports sent using the second mode.

[0310] In one example, if a network device determines that a first communication performance is lower than a second communication performance, the first information can instruct the terminal device to reduce the proportion of CSI reports sent using the first mode and increase the proportion of CSI reports sent using the second mode.

[0311] In another example, if the second information is a comparison result of the first communication performance and the second communication performance, the network device can send the first information to the terminal device based on the comparison result.

[0312] In another example, if the second information is an adjustment request message, the network device can send the first information to the terminal device based on the adjustment request message.

[0313] In another example, after evaluating the first and second communication performance, the terminal device can automatically adjust the proportion of CSI reports sent using the first mode and / or the proportion of CSI reports sent using the second mode. In this case, the terminal device can inform the network device of the change in operating mode while providing CSI report feedback.

[0314] For example, at a certain moment, the terminal device should have used the first mode to send the CSI report, but based on the evaluation results, it chooses to use the second mode. In this case, the terminal device can indicate the change in the CSI report sending mode while sending the report. Optionally, the terminal device can also send the first and second communication performance metrics to the network device while sending the CSI report.

[0315] Optionally, the method 400 may further include step 460.

[0316] 460. The terminal device adjusts the proportion of CSI reports sent using the first mode and / or the proportion of CSI reports sent using the second mode based on the first information.

[0317] For example, if the first information instructs the terminal device to increase the proportion of sending CSI reports using the first mode and decrease the proportion of sending CSI reports using the second mode, the terminal device can increase the proportion of sending CSI reports using the first mode and decrease the proportion of sending CSI reports using the second mode according to the first information.

[0318] Optionally, before the second device sends the first information to the first device based on the first communication performance and the second communication performance, the method may further include:

[0319] The network device sends a second activation message to the terminal device. The second activation message is used to activate the target configuration in the first configuration information.

[0320] In some embodiments, the terminal device sends a CSI report to the network device based on first configuration information, including:

[0321] The terminal device sends a CSI report to the network device according to the target configuration.

[0322] For example, the target configuration may include a set of N, K and distribution indication information, which the terminal device can use to send a CSI report to the network device.

[0323] Optionally, the first configuration information is used to indicate the first CSI report configuration used by the terminal device to send CSI reports. The first CSI report configuration is used to instruct the terminal device to send N CSI reports to the network device, where N is a positive integer. In the first mode, the number of CSI reports sent by the terminal device is K, and in the second mode, the number of CSI reports sent by the terminal device is NK, where K is an integer greater than or equal to 0 and less than or equal to N.

[0324] In some embodiments, the first CSI report configuration is further configured to instruct the terminal device to send multiple sets of N CSI reports.

[0325] For example, the configuration of this first CSI report can be found in the previous section on... Figure 3 For the sake of brevity, the relevant descriptions will not be repeated.

[0326] Optionally, the first configuration information is used to indicate the first CSI report group configuration used by the terminal device to send CSI reports. The first CSI report group configuration contains N second CSI report configurations, where N is a positive integer. Each second CSI report configuration is used to indicate one CSI report of the terminal device. The number of CSI reports sent by the terminal device in the first mode is K, and the number of CSI reports sent by the terminal device in the second mode is NK, where K is an integer greater than or equal to 0 and less than or equal to N.

[0327] In some embodiments, each second CSI report is configured to instruct the terminal device to send multiple CSI reports.

[0328] For example, the configuration of this first CSI reporting group can be found in the previous section on... Figure 4 For the sake of brevity, the relevant descriptions will not be repeated.

[0329] Optionally, the first configuration information is used to indicate the second CSI report group configuration used by the terminal device to send CSI reports. The second CSI report group configuration includes two third CSI report configurations. One of the two third CSI report configurations is used to indicate the terminal device to send CSI reports using a first mode, and the other of the two third CSI report configurations is used to indicate the terminal device to send CSI reports using a second mode.

[0330] In some embodiments, the terminal device sends CSI reports using a first mode for a period of NT / K, and the terminal device sends CSI reports using a second mode for a period of T, where N is a positive integer and K is a natural number. When K equals 0, the terminal device does not send CSI reports using the first mode.

[0331] For example, the configuration of this second CSI reporting group can be found in the previous section on... Figure 5 For the sake of brevity, the relevant descriptions will not be repeated.

[0332] Optionally, the first configuration information is also used to indicate a list of scale sets, each scale set in the list of scale sets including a set of scale configuration information, the scale configuration information including one or more of the following: N, K, distribution indication information, wherein the distribution indication information is used to indicate the distribution of the first mode and the second mode.

[0333] Optionally, the first information is a first activation message, which is used to activate a proportion set in the proportion set list, and N, K, and distribution indication information are used to implement the first CSI report configuration; or,

[0334] N, K, and distribution indication information are used to configure the first CSI reporting group; or...

[0335] N, K, and distribution indication information are used to configure the second CSI reporting group.

[0336] It should be understood that, in this case, the technical solution for adjusting the proportion of CSI reports sent using the first mode and / or the proportion of CSI reports sent using the second mode based on the first information can be found in the preceding text regarding... Figure 6 The relevant descriptions of (a) and (b) in the text will not be repeated for the sake of brevity.

[0337] It should be understood that the first activation message can be a MAC CE message or a DCI message.

[0338] In some embodiments, when the first activation message is a MAC CE message, the MAC CE message may also directly carry a set of N, K, and distribution indication information. Therefore, after receiving the MAC CE message, the terminal device can send a CSI report based on the N, K, and distribution indication information. This technical solution allows the terminal device to make rapid adjustments, improving the efficiency of adjusting the sending of CSI reports using different modes. It should be understood that the MAC CE message may also carry only one or more of the N, K, and distribution indication information, with other information using pre-agreed or currently used configurations.

[0339] In some embodiments, the target configuration mentioned above may include a scale set from a scale set list.

[0340] Optionally, the first configuration information can be carried in an RRC message.

[0341] The first mode in this application embodiment can be a CSI feedback mode based on artificial intelligence (AI); the second mode can be a CSI feedback mode based on codebook. It should be understood that the first mode and the second mode can also be other CSI feedback modes, which are not limited in this application embodiment.

[0342] Based on the embodiments of this application, the network device can configure a hybrid operating mode of a first mode and a second mode for the terminal device. The terminal device sends a CSI report according to the configuration information of the network device. The terminal device can evaluate the performance of the two communication modes and send the evaluation result to the network device. The network device sends information to the terminal device based on the evaluation result, instructing the terminal device to adjust the ratio of sending CSI reports using the first mode and the second mode. This technical solution can effectively monitor the performance of the two modes with low overhead; furthermore, it can adjust the operating mode of the terminal device sending CSI reports in real time or near real time.

[0344] 510. The test device sends third configuration information to the network device, which is used to indicate that the network device is operating in a hybrid working mode of the first mode and the second mode.

[0346] Optionally, the third configuration information may include test start time, test duration or test data volume, evaluation metrics, etc.

[0347] The first mode can be an AI-based CSI feedback mode; the second mode can be a codebook-based CSI feedback mode.

[0348] It should be understood that in some embodiments, the network device and the test device can be the same device.

[0349] 520. Based on step 510, the network device sends fourth configuration information to the terminal device, which instructs the terminal device to send CSI reports using a combination of the first mode and the second mode.

[0350] The fourth configuration information can be found in the previous description of the first configuration information, and will not be repeated here for the sake of brevity.

[0351] Optionally, the fourth configuration information may also include test start time, test duration or test data volume, evaluation metrics, etc.

[0352] It should be understood that in some embodiments, the fourth configuration information may also be sent by the test device to the terminal device.

[0353] 530, the terminal device sends a CSI report to the network device based on the fourth configuration information.

[0354] It should be understood that the specific process by which the terminal device sends a CSI report to the network device based on the fourth configuration information can be found in the relevant description of step 320, and will not be repeated here for the sake of brevity.

[0355] 540. Network equipment evaluation: first and second communication performance.

[0356] It should be understood that the relevant description of step 540 can be found in the relevant description of step 330, and for the sake of brevity, it will not be repeated.

[0360] 560. The testing equipment compares the performance based on the first and second communication performance.
