[0117] The methods and devices provided in the embodiments of the present application are based on the same or similar technical concepts. Since the principles of solving problems by the methods and devices are similar, the implementation of the devices and methods can refer to each other, and the repeated parts will not be repeated.

[0118] Figure 1 is a schematic diagram of a communication system to which an embodiment of the present application is applicable. As shown in Figure 1, the wireless communication system may include a network device 110 and one or more terminal devices (for example, the terminal device 121 and the terminal device 122 shown in Figure 1) for communication. When the network device 110 sends a signal, the network device 110 is a transmitter, and the terminal device 121 or the terminal device 122 is a receiver. Conversely, when the terminal device 121 or the terminal device 122 sends a signal, the terminal device 121 or the terminal device 122 is a transmitter, and the network device 110 is a receiver. Optionally, the terminal device 121 and the terminal device 122 may also communicate. When the terminal device 121 sends a signal to the terminal device 122, the terminal device 121 is a transmitter, and the terminal device 122 is a receiver. Conversely, when the terminal device 122 sends a signal to the terminal device 121, the terminal device 122 is a transmitter, and the terminal device 121 is a receiver.

[0119] The terminal device 121 or the terminal device 122 may also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), road side unit (RSU), etc. The terminal device in the embodiment of the present application can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a robotic arm, a smart home device, a speaker, etc., and can also be a wireless terminal used in scenarios such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality (VR), augmented reality (AR), industrial control, self-driving, remote medical, smart grid, transportation safety, smart city, smart wear, smart transportation, and smart home. In this application, the aforementioned terminal devices and chips that can be applied to the aforementioned terminal devices are collectively referred to as terminal devices. It should be understood that the embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal devices.

[0120] The network device 110 may be a device in a wireless network, and the network device 110 may also be referred to as a network apparatus. For example, the network device 110 may be a radio access network (RAN) node that connects a terminal device to a wireless network, and may also be referred to as an access network device. The network device 110 includes, but is not limited to, an evolved Node B (eNB), a radio network controller (RNC), a Node B (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (e.g., a home evolved Node B, or home Node B, HNB), a baseband unit (BBU), an access point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP), a reception point (RP), or a transmission and reception point (TRP), and may also be a network device in a 5G mobile communication system or a network device in other future network systems. For example, a next generation NodeB (gNB) or a transmission reception point (TRP) or TP in an NR system; or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G mobile communication system; or the network device 110 may also be a network node constituting a gNB or a transmission point, such as a BBU or a distributed unit (DU).

[0121] In some deployments, the network device 110 may include a centralized unit (CU) and a distributed unit (DU). The network device 110 may also include an active antenna unit (AAU). The CU implements some of the gNB's functions, while the DU implements some of the gNB's functions. For example, the CU is responsible for processing non-real-time protocols and services, implementing the functions of the radio resource control (RRC) layer. The DU is responsible for processing physical layer protocols and real-time services, implementing the functions of the radio link control (RLC), media access control (MAC), and physical (PHY) layers. In some deployments, the CU may also be divided into a centralized unit control plane (CU-CP) node and a centralized unit user plane (CU-UP) node. The CU-CP is responsible for control plane functions, while the CU-UP is responsible for user plane functions. For example, the CU-CP and CU-UP may be implemented by different functional entities and connected via an E1 interface. The CU-CP and CU-UP may be coupled with the DU to jointly perform the functions of the base station. The CU control plane (CU-CP) also includes a further segmented architecture, splitting the existing CU-CP into CU-CP1 and CU-CP2. CU-CP1 includes various radio resource management functions, while CU-CP2 only includes radio resource control (RRC) and PDCP-C functions (the basic functions of control plane signaling at the packet data convergence protocol (PDCP) layer).

[0122] The communication system shown in FIG1 may apply 4G, 5G, 6G or future communication systems, etc., and the embodiments of the present application are not limited thereto.

[0123] For the convenience of description in the following embodiments, the device numbers are omitted. For example, “terminal device” means “terminal device 121 or terminal device 122 ”, and “network device” means “network device 110 ”.

[0124] In the embodiments of the present application, terminal devices and network devices are used as examples for description. In actual applications, the embodiments of the present application can also be applied to other scenarios, such as satellite communication scenarios.

[0125] In existing communication systems, artificial intelligence (AI) models can be introduced in some scenarios. For example, AI models can be introduced in channel state information (CSI) feedback. When using AI models, communication equipment needs to monitor the accuracy of the AI ​​models. If the AI ​​model is inaccurate, it will lead to poor system performance. Therefore, how to monitor the accuracy of the AI ​​model is an urgent problem to be solved. In one possible implementation method, in the scenario of the AI ​​CSI model introduced by CSI feedback, the output result of the AI ​​CSI model can be compared with the expected output result. If the output result of the AI ​​CSI model differs greatly from the expected output result, it means that the performance of the AI ​​CSI model is poor. When the network device monitors the AI ​​CSI model, the terminal device needs to send the original information to the network device, and the network device compares the output result of the AI ​​CSI model with the original information to determine the performance of the AI ​​CSI model. When the terminal device monitors the AI ​​CSI model, the network device needs to send the original information to the terminal device, and the terminal device compares the output result of the AI ​​CSI model with the original information to determine the performance of the AI ​​CSI model. However, in the process of monitoring the AI ​​CSI model, network devices or terminal devices need to send original information, which results in high overhead.

[0126] In an existing communication system, a terminal device can access a network device and communicate with the network device through random access. During the random access process, the terminal device can send a preamble, and the network device can detect the preamble of the terminal device. In the prior art, the preamble can be generated based on the ZC (Zadoff-Chu) sequence. When the root sequences used are different, the generated preambles are non-orthogonal. When multiple terminal devices send different preambles on the same time-frequency resources, there is interference between the different preambles, resulting in a decrease in detection performance. In addition, when the network device detects the preamble, the network device can perform a correlation operation based on the local sequence and the signal received by the network device, and compare the result of the correlation operation with the threshold to determine whether a specific preamble is detected. However, this threshold cannot meet all usage scenarios. For example, if the threshold used in a scenario with fewer terminal devices is the same as that used in a scenario with more terminal devices, the detection accuracy cannot be met. Therefore, it is necessary to introduce AI technology or AI models in the random access process to improve the detection performance in random access. However, how to monitor the accuracy of the AI ​​model in the random access process after the introduction of AI technology is an urgent problem to be solved.

[0127] In an embodiment of the present application, the network device can send a first indication message to the terminal device, and the first indication message is used to instruct the terminal device to send a first AI preamble code. The terminal device can send the first AI preamble code to the network device according to the first indication message. The network device can receive a first signal including the first AI preamble code. The network device can use the first AI preamble code to monitor the AI ​​model, thereby solving the problem of monitoring the AI ​​model.

[0128] The following describes a communication method 200 provided in an embodiment of the present application in conjunction with FIG2 . As shown in FIG2 , the communication method 200 includes:

[0131] Optionally, the AI ​​model refers to an AI model in an AI-based random access process. Optionally, in the first case, the AI ​​model may include a first AI sub-model for generating a first AI preamble set and a second AI sub-model for detecting the AI ​​preamble. In this way, the terminal device or the network device may determine the first AI preamble set based on the first AI sub-model. That is, the AI ​​model may include a first AI sub-model for generating a first AI preamble set and a second AI sub-model for detecting the AI ​​preamble.

Optionally, the network device may indicate the first AI preamble set to the terminal device. Optionally, in the above two cases, the first AI preamble set may have no intersection with the second AI preamble set used for conventional AI-based random access. For example, there are a total of 64 AI preambles in a cell covered by a network device, and X of these AI preambles are used for AI-based random access of terminal devices in the cell. At this time, the second AI preamble set includes X AI preambles, where X is a positive integer. The first AI preamble set includes 64-X AI preambles, and these 64-X preambles are specifically used for AI model monitoring or specifically for AI model training. Optionally, in the above first case, the first AI sub-model can be used to generate the first AI preamble set and the second AI preamble set. Optionally, in the above second case, the AI ​​model includes a first AI preamble set, a second AI preamble set, and a second AI sub-model for detecting AI preambles.

[0132] Optionally, the first indication information is used to instruct the terminal device to send a first AI preamble code in the RRC connection state.

[0133] Optionally, the first indication information may instruct the terminal device to periodically send a first AI preamble code.

[0134] Optionally, the first indication information may instruct the terminal device to periodically send a first AI preamble code in the RRC connection state.

[0135] Optionally, the network device may send the first indication information through dynamic indication, static indication or semi-static indication, for example, the DCI includes the first indication information, and the first indication information may instruct the terminal device to send the first AI preamble code non-periodically. Optionally, the DCI may be a dedicated DCI indication or a public DCI indication, such as a Group DCI indication. For another example, the RRC signaling includes the first indication information, and the first indication information may instruct the terminal device to send the first AI preamble code and the sending period of the terminal device to send the first AI preamble code. Optionally, the first indication information may instruct the terminal device to send the first AI preamble code semi-statically or semi-continuously, for example, the medium access control-control element (MAC-CE) signaling includes the first indication information, and the first indication information is used to activate the preconfigured period of the network device, and the terminal device may periodically send the first AI preamble code.

[0136] Optionally, the network device may also send first configuration information, and the terminal device may receive the first configuration information, where the first configuration information is used to configure the first time-frequency resource for the terminal device to send the first AI preamble. For example, the first configuration information may indicate the sub-carrier space (SCS) corresponding to the first time-frequency resource. For another example, the first configuration information may directly indicate the location of the first time-frequency resource, such as the location of the time-frequency domain resource such as the resource element (RE) or resource block where the first time-frequency resource is located; for another example, the network device may pre-configure a time-frequency resource set, and the network device may indicate the index of the first time-frequency resource in the time-frequency resource set through the first configuration information.

[0137] Optionally, the network device may send the first indication information and the first configuration information in one message, and the terminal device may receive the first indication information and the first configuration information in one message, or the network device may send the first indication information and the first configuration information in different messages, and the terminal device may obtain the first indication information and the first configuration information in different messages. The embodiment of the present application does not limit this. Optionally, the first indication information may instruct the terminal device to send the first AI preamble, or may instruct the terminal device to send the first time-frequency resource of the first AI preamble, that is, one message may instruct the terminal device to send the first AI preamble, and another message may instruct the terminal device to send the first time-frequency resource of the first AI preamble, or one message may simultaneously instruct the terminal device to send the first AI preamble and the terminal device to send the first time-frequency resource of the first AI preamble, for example, the first indication information may indicate the first AI preamble and the first time domain resource, for example, the first indication information may indicate the index of the first AI preamble and the index of the first time domain resource in the preconfigured time-frequency resource set. The embodiment of the present application does not limit this.

[0138] Optionally, before the network device sends the first configuration information or the first indication information, the communication method 200 also includes: the terminal device can send the first capability information to the network device, the network device can receive the first capability information from the terminal device, the first capability information is used to indicate the time-frequency resource range supported by the terminal device, and the network device can determine the first time-frequency resource within the time-frequency resource range supported by the terminal device, that is, the terminal device can report the time-frequency resource range supported by itself, and the network device can determine the first time-frequency resource for sending the first AI preamble code within the time-frequency resource range supported by the terminal device. In other words, the network device can determine the first time-frequency resource for the terminal device to send the first AI preamble code within the time-frequency resource range supported by the terminal device. Of course, the network device can also configure the first time-frequency resource for the terminal device to send the first AI preamble code to the terminal device according to its own implementation. This embodiment of the present application does not limit this. Optionally, the first capability information can indicate the time-frequency resource range supported by the terminal device by indicating at least one of the time domain length, frequency domain length, amplitude range or phase range. Optionally, the time-frequency resource range supported by the terminal device may be the time-frequency resource range supported when the terminal device sends an AI preamble, or the time-frequency resource range supported when the terminal device generates an AI preamble.

[0139] Optionally, before the network device sends the first configuration information or the first indication information, the terminal device may send second capability information to the network device, and the network device may receive the second capability information, where the second capability information is used to indicate that the terminal device supports the generated AI preamble. The network device may determine the first AI preamble from the AI ​​preambles supported by the terminal device. Optionally, the second capability information may directly indicate that the terminal device supports the generated AI preamble, for example, the second capability information may indicate the sequence of AI preambles supported by the terminal device or the corresponding index of the sequence of AI preambles supported by the terminal device. It may also indirectly indicate that the terminal device supports the generated AI preamble, for example, the second capability information may indicate that the terminal device supports the generated AI preamble by indicating the description information of the generated AI preamble, for example, the second capability information may indicate the length of the AI ​​preamble supported by the terminal device (such as at least one of the time domain length, frequency domain length, or number of time domain channels when the AI ​​preamble is resource mapped); for example, the second capability information may indicate the index of the AI ​​model corresponding to the generated AI preamble supported by the terminal device, etc. Optionally, the terminal device may send the first capability information and the second capability information simultaneously, or may send the first capability information and the second capability information separately, which is not limited in this embodiment of the present application.

[0140] Optionally, the first AI preamble set includes AI preambles supported for generation by the terminal device, and the AI ​​preambles supported for generation by the terminal device include the first AI preamble. Optionally, the first AI preamble set is specifically used for AI model monitoring, or the first AI preamble set is specifically used for AI model training, or the first AI preamble set is specifically for AI model monitoring and AI model training. The first AI preamble set is determined by the first AI sub-model, for example, it can be determined by the network device according to the first AI sub-model and indicated to the terminal device, or the network device indicates the first AI sub-model to the terminal device, and the terminal device can determine the first AI preamble set according to the first AI sub-model, or the first AI preamble set can be part of the AI ​​model, and the network device can indicate the first AI preamble set to the terminal device.

[0141] Optionally, the first AI preamble code set is specifically used for AI model monitoring, and the time-frequency resources corresponding to the AI ​​preamble codes included in the first AI preamble code set are the same as the time-frequency resources corresponding to the AI ​​preamble codes used for conventional random access within the cell. That is, since the AI ​​preamble codes in the first AI preamble code set are used for AI model monitoring, the AI ​​model is used to detect the AI ​​preamble codes for random access. Therefore, in order to better monitor the AI ​​model, the time-frequency resources corresponding to the AI ​​preamble codes included in the first AI preamble code set can overlap with the time-frequency resources of the AI ​​preamble codes used for conventional random access within the cell. In this way, the AI ​​preamble codes in the first AI preamble code set can better simulate or simulate the AI ​​preamble codes in the actual random access process, so the AI ​​preamble codes in the first AI preamble code set can also be better used to monitor the AI ​​model.

[0142] Optionally, the first AI preamble code set is specifically used for AI model training, and the time-frequency resources corresponding to the AI ​​preamble codes included in the first AI preamble code set are different from the time-frequency resources corresponding to the AI ​​preamble codes used for conventional random access within the cell. That is, since the AI ​​preamble codes in the first AI preamble code set are used for AI model training, that is, in order to train AI preamble codes or AI preamble code detection models adapted to new scenarios (such as other time-frequency resources), the time-frequency resources corresponding to the AI ​​preamble codes included in the first AI preamble code set are different from the time-frequency resources of the AI ​​preamble codes used for conventional random access within the cell. In this way, the AI ​​model can be better trained.

[0143] Optionally, before the network device sends the first configuration information or the first indication information, the terminal device may send third capability information to the network device, and the network device may receive the third capability information, where the third capability information is used to indicate whether the terminal device supports assisted AI model monitoring and / or assisted AI model training. If the third capability information is used to indicate that the terminal device supports assisted AI model monitoring, the network device may send first indication information, where the first indication information is used to instruct the terminal device to send a first AI preamble for AI model monitoring; if the third capability information is used to indicate that the terminal device supports assisted AI model training, the network device may send first indication information, where the first indication information is used to instruct the terminal device to send a first AI preamble for AI model training; if the third capability information is used to indicate that the terminal device supports assisted AI model monitoring and assisted AI model training, the network device may send first indication information, where the first indication information is used to instruct the terminal device to send a first AI preamble for AI model monitoring and AI model training; if the third capability information is used to indicate that the terminal device does not support assisted AI model monitoring or assisted AI model training, the network device may not send the first indication information. Optionally, the terminal device may send at least two of the first capability information, the second capability information and the third capability information at the same time, or may send the first capability information, the second capability information and the third capability information separately. This embodiment of the present application does not limit this.

[0144] Optionally, before S210, the communication method further includes: the network device sends second configuration information, the terminal device receives the second configuration information, and the second configuration information is used to instruct the terminal device to send a first time domain offset and / or a first frequency domain offset for the first AI preamble. Optionally, the second configuration information is used to instruct the terminal device to generate and send a first time domain offset and / or a first frequency domain offset for the first AI preamble. For example, the unit of the first time domain offset can be a basic unit of timing advance (TA) (for example, in the LTE system, 1 TA is 0.52 microseconds), or it can be a multiple of the basic unit of TA, or it can be in units of other time granularities such as the number of time domain sampling points, the number of symbols, the number of time slots, the number of subframes, the number of frames, or in absolute time units such as nanoseconds, microseconds, etc. For another example, the unit of the first frequency domain offset can be Hertz (HZ) or ppm, or it can also be a normalized value relative to the subcarrier spacing used, or other ways of describing the frequency domain offset, without limitation. If the unit of the first frequency domain offset is ppm, and the first frequency domain offset can be y ppm, the terminal device can determine the reference frequency according to the configuration method of the network device or a predefined method, and then determine the actual first frequency domain offset according to the reference frequency and y ppm. For example, the terminal device can determine the first frequency domain offset by multiplying the reference frequency by y ppm. That is to say, at this time, the network device can indirectly indicate the first frequency offset by indicating y ppm. For example, the reference frequency is the current carrier frequency or crystal oscillator frequency of the terminal device. Optionally, the network device can send the second configuration information through dynamic indication, static indication or semi-static indication. Optionally, the network device can send the second configuration information through an RRC message, and the terminal device can receive the second configuration information through an RRC message.

Optionally, the network device may send the second configuration information through downlink control information (DCI), and the terminal device may receive the second configuration information through the DCI. Optionally, the DCI may carry the first indication information and the second configuration information at the same time. For example, the first field in the DCI is used to carry the first indication information, and the second field in the DCI is used to carry the second configuration information. The first field is continuous with the second field. Optionally, the position of the first field in the DCI is located before the second field. Optionally, the DCI may be a dedicated DCI or a public DCI.Optionally, the network device can pre-configure a time-frequency offset set and / or a pre-configured frequency domain offset set, and the second configuration information can configure the index of the first time domain offset in the pre-configured time domain offset set, and / or can configure the index of the first frequency domain offset in the pre-configured frequency domain offset set.

Alternatively, one piece of information may simultaneously instruct the terminal device to send the first AI preamble and the first time-frequency resource for the terminal device to send the first AI preamble; or one piece of information may simultaneously instruct the terminal device to send the first AI preamble and the terminal device to send the first time domain offset and / or the first frequency domain offset of the first AI preamble. For example, the first indication information may indicate the first AI preamble, and the first time domain offset and / or the first frequency domain offset. For example, the first indication information may indicate the index of the first AI preamble, and the index of the first time domain offset in the preconfigured time domain offset set and / or the index of the first frequency domain offset in the preconfigured frequency domain offset set. This embodiment of the present application is not limited to this. Alternatively, one piece of information may simultaneously instruct the terminal device to send the first time domain resource for the first AI preamble, and the first time domain offset and / or the first frequency domain offset for the first AI preamble. Or, one piece of information may simultaneously instruct the terminal device to send the first AI preamble, and the first time domain offset and / or the first frequency domain offset for the first AI preamble. Or, one piece of information may simultaneously instruct the terminal device to send the first AI preamble, the first time domain resource for the terminal device to send the first AI preamble, and the first time domain offset and / or the first frequency domain offset for the terminal device to send the first AI preamble.

[0147] Optionally, after the network device determines to perform AI model training or AI model monitoring, it can trigger the execution of S210. For example, after the network device periodically needs to perform AI model training or AI model monitoring, each period can trigger the execution of S210. Exemplarily, the period can be determined by the network device. Optionally, the network device can perform AI model training or AI model monitoring non-periodically. For example, when the network device uses the AI ​​model to detect the AI ​​preamble (for example, when using the second AI sub-model to detect the AI ​​preamble), the detected AI preamble is inaccurate, then the network device determines that AI model monitoring or AI model training is required, and therefore S210 can be executed. In other words, the network device can monitor the AI ​​model or train the AI ​​model periodically, or it can monitor the AI ​​model or train the AI ​​model non-periodically based on its own implementation.

For example, the first time domain offset is N time domain units. Optionally, the first signal can be a frequency domain signal or a time domain signal. If the first signal is a frequency domain signal, the terminal device offsets N time domain units based on the starting position of the first time-frequency resource.

If the first signal is a time domain signal, the first signal can be the terminal device performing an inverse fast Fourier transform (inverse fast fourier transform) on the frequency domain signal including the first AI preamble code. transform, IFFT), optionally, the first signal can be a time domain signal before adding a cyclic prefix, or a time domain signal after adding a cyclic prefix, and the terminal device offsets N time domain units based on the starting point of the time domain signal or other indications or predefined time domain signal starting points; for another example, the first frequency domain offset is m, m is a normalized value relative to the subcarrier spacing used, and the first signal can be a time domain signal obtained by the terminal device by IFFTing the frequency domain signal including the first AI preamble code, and the terminal device can multiply each time domain sampling point by a coefficient.

Alternatively, the second configuration information is used to instruct the terminal device to generate and send a first time domain offset and / or a first frequency domain offset of a first AI preamble code.

In some cases, the network device can simultaneously schedule multiple terminal devices to send AI preambles, and the network device can use the AI ​​preambles sent by multiple terminal devices to perform AI model monitoring or AI model training. That is, in order to facilitate the description of sending and receiving the first signal, S220 describes that the terminal device sends a first signal including the first AI preamble according to the first indication information, and the network device receives the first signal including the first AI preamble. In some cases, the signal received by the network device may include other signals in addition to the first signal. In this case, the network device may receive a superimposed signal. For example, the network device can schedule the transmission of other signals in addition to the first AI preamble on the first time-frequency resource. In this case, the signal detected by the network device can be a superposition of the first signal and the interference signal formed by other preambles and / or non-preamble signals. When detecting the AI ​​model or training the AI ​​model, the network device can input the superimposed signal into the AI ​​model to detect whether the superimposed signal includes the first AI preamble.

The network device can detect the first signal and detect the first signal through the AI ​​model to determine whether the AI ​​model is accurate or inaccurate, thereby providing a method for monitoring the AI ​​model in a random access scenario, or the network device can train the AI ​​model based on the first signal and the first AI preamble code as a label, thereby providing a method for training the AI ​​model in a random access scenario. Since in the communication method 200, the monitoring and training of the AI ​​model are performed on the network device side, it can be considered that the terminal device assists the network device in monitoring and training the AI ​​model.

[0158] In some scenarios, the terminal device can monitor the information of the AI ​​preamble sent by the terminal device and send the monitored information to the network device. The network device can determine whether the AI ​​model is accurate based on the information monitored by the terminal device, thereby realizing the monitoring of the AI ​​model.

[0166] Optionally, the network device may send the first configuration information and the second configuration information to the terminal device at the same time, or may send the first configuration information and the second configuration information to the terminal device separately. This embodiment of the present application does not limit this.

[0167] S320, the terminal device sends first information to the network device according to the first configuration information, and the network device receives the first information, where the first information includes information on sending an AI preamble code.

[0168] Optionally, the communication method 300 also includes: the terminal device sends an AI preamble code at least once, and the network device can receive the AI ​​preamble code sent by the terminal device. If the network device receives the AI ​​preamble code sent by the terminal device at a certain time, the network device can send a response to the AI ​​preamble code to the terminal device. For example, the response information can be a random access response (RAR) information. After the terminal device receives the response, it can be determined that the AI ​​preamble code is sent successfully; if the network device does not receive or detect the AI ​​preamble code sent by the terminal device at a certain time, the network device will not send any response to the terminal device. If the terminal device does not receive a response to the AI ​​preamble code within a preset time period, it can be determined that the AI ​​preamble code has failed to be sent.

[0169] Optionally, the first information includes information about the AI ​​preamble sent by the terminal device. That is, the terminal device can monitor the information about the AI ​​preamble sent by itself, and generate the first information based on the monitored information and send it to the network device.

[0170] Optionally, if the first configuration information is used to configure the terminal device to record the information of the terminal device sending the AI ​​preamble code, the terminal device can record the information of the terminal device sending the AI ​​preamble code according to the first configuration information, and send the first information to the network device, the first information including the information of the terminal device sending the AI ​​preamble code recorded by the terminal device.

Optionally, if the first configuration information is used to configure the terminal device to monitor information on the AI ​​preamble sent within the first time window, the terminal device may monitor the information on the AI ​​preamble sent within the first time window according to the first configuration information, and the terminal device may not monitor information on the AI ​​preamble sent by the terminal device outside the first time window. At this time, the first information includes information on the AI ​​preamble sent by the terminal device within the first time window. For example, as shown in FIG4 , the terminal device sent an AI preamble a total of 10 times, and within the first time window, the terminal device sent an AI preamble a total of 6 times, from the 3rd to the 8th AI preamble. Therefore, the first information includes information on the 6 AI preambles sent by the terminal device within the first time window. Optionally, if the first configuration information is used to configure the terminal device to monitor the information of the terminal device successfully sending the AI ​​preamble code and the information of the terminal device failing to send the AI ​​preamble code within the first time window, the terminal device can monitor the information of the terminal device successfully sending the AI ​​preamble code and the information of the terminal device failing to send the AI ​​preamble code within the first time window according to the first configuration information. The first information may include the information of the terminal device successfully sending the AI ​​preamble code and the information of the terminal device failing to send the AI ​​preamble code within the first time window. For example, as shown in Figure 4, the terminal device sent the AI ​​preamble code a total of 10 times, and the terminal device sent the AI ​​preamble code 3 to 8 times, a total of 6 AI preamble codes within the first time window. Therefore, the first information includes the information of the terminal device failing to send and the information of the terminal device successfully sending these 6 AI preamble codes within the first time window. Optionally, if the first configuration information is used to configure the terminal device to monitor the information of the terminal device's failure to send the AI ​​preamble code within the first time window, the terminal device can monitor the information of the terminal device's failure to send the AI ​​preamble code within the first time window according to the first configuration information. The first information may include the information of the terminal device's failure to send the AI ​​preamble code within the first time window. For example, as shown in Figure 5, the terminal device sent the AI ​​preamble code a total of 10 times. Within the first time window, the terminal device sent the AI ​​preamble code from the 3rd to the 8th time, a total of 6 AI preamble codes. Therefore, the 4th and 7th AI preamble codes failed to be sent within the first time window. The first information includes the information of the failure to send the 4th and 7th AI preamble codes within the first time window.Optionally, if the first configuration information configures the terminal device with information on the failed AI preamble code transmission, and the information on the terminal device's failure to transmit the AI ​​preamble code includes at least one of the number of failures of the AI ​​preamble code, the identifier of the failed AI preamble code, the transmission time of the failed AI preamble code, the transmission power of the failed AI preamble code, or the start and end time of the failed AI preamble code transmission, then the terminal device may monitor the number of failures of the terminal device to transmit the AI ​​preamble code, the identifier of the failed AI preamble code, the transmission time of the failed AI preamble code, the transmission power of the failed AI preamble code, or the start and end time of the failed AI preamble code transmission within the first time window according to the first configuration information.

Optionally, the first time window can be a static time window, for example, determined by configuring the start and end time points of the first window. Optionally, the first time window can be a dynamic time window, for example, determined by configuring the trigger events corresponding to the start and end time points. For example, the first time window can be the time period from the x1th AI preamble sending moment to the x2th AI preamble sending moment. As shown in FIG6 , x1 can be 3, and x2 can be 8. The first time window is from the 3rd AI preamble sending moment to the 8th AI preamble sending moment. The first time window can include the x1th AI preamble sending moment and / or the x2th AI preamble sending moment. The first time window may include the time when the AI ​​preamble is sent for the x1th time, or the time when the AI ​​preamble is sent for the x2th time. For another example, the first time window may be the time period from the time when the AI ​​preamble fails to be sent for the x3th time to the time when the AI ​​preamble is successfully sent for the first time. For example, as shown in FIG7 , x3 is 3, the terminal device successfully sends the AI ​​preamble for the 8th time, and fails to send the AI ​​preamble for the 1st to the 7th time. Then, the first time window is the time when the AI ​​preamble is sent for the 3rd time to the time when the AI ​​preamble is sent for the 8th time.

[0172] Optionally, if the first configuration information is used to configure the monitoring of the successful sending of the AI ​​preamble and the information of the failed sending of the AI ​​preamble, the terminal device can monitor the information of the successful sending of the AI ​​preamble and the information of the failed sending of the AI ​​preamble by the terminal device according to the first configuration information. The first information may include the information of the successful sending of the AI ​​preamble by the terminal device and the information of the failed sending of the AI ​​preamble by the terminal device. For example, as shown in Figure 8, the terminal device sent the AI ​​preamble 10 times in total, and the terminal device recorded the successful sending and failed sending of the AI ​​preamble for these 10 times. Therefore, the first information includes the failed sending and successful sending of the AI ​​preamble by the terminal device for these 10 times. Optionally, the first configuration information is used to configure the terminal device to monitor information on the terminal device's failure to send an AI preamble code. The terminal device can monitor information on the terminal device's failure to send an AI preamble code based on the first configuration information. The first information may include information on the terminal device's failure to send an AI preamble code. For example, as shown in Figure 9, the terminal device sent an AI preamble code a total of 10 times. The terminal device failed to send the AI ​​preamble code for the 2nd, 4th and 7th times. The terminal device records information on these 3 failures to send the AI ​​preamble code. Therefore, the first information includes information on the terminal device's failure to send the AI ​​preamble code for the 2nd, 4th and 7th times. Optionally, if the first configuration information is used to configure the terminal device to record at least one of the number of failed AI preamble transmission failures, the identifier of the failed AI preamble transmission failures, the sending time of the failed AI preamble transmission failures, the sending power of the failed AI preamble transmission failures, or the start and end times of the failed AI preamble transmission failures, the terminal device can monitor at least one of the number of failed AI preamble transmission failures, the identifier of the failed AI preamble transmission failures, the sending time of the failed AI preamble transmission failures, or the sending power of the failed AI preamble transmission failures according to the first configuration information. The first information may include at least one of the number of failed AI preamble transmission failures, the identifier of the failed AI preamble transmission failures, the sending time of the failed AI preamble transmission failures, or the sending power of the failed AI preamble transmission failures of the terminal device.

[0173] Optionally, if the first configuration information configures a failure tag for an AI preamble code that fails to be sent by the terminal device or a success tag for an AI preamble code that is successfully sent by the terminal device. If the terminal device fails to send an AI preamble code once, the terminal device may also record the failure tag of the AI ​​preamble code when recording the information of the AI ​​preamble code. At this time, the first information may include the failure tag of the AI ​​preamble code. For example, when the first configuration information configures the terminal device to monitor the information of the successful sending of the AI ​​preamble code during the entire AI preamble sending period or within the first time window and the information of the failed sending of the AI ​​preamble code by the terminal device, when the AI ​​preamble code fails to be sent, the terminal device may also record the failure tag; if the terminal device successfully sends an AI preamble code once, the terminal device may also record the success tag of the AI ​​preamble code when recording the information of the AI ​​preamble code. For example, when the first configuration information configures the terminal device to monitor the information of the successful sending of the AI ​​preamble code during the entire AI preamble sending period or within the first time window and the information of the failed sending of the AI ​​preamble code by the terminal device, when the AI ​​preamble code is successfully sent, the terminal device may also record the failure success tag.

[0174] Optionally, if the terminal device receives the second configuration information, and the second configuration information is used to configure the sending of the first information after N failures in sending the AI ​​preamble, the terminal device can record the number of failures in sending the AI ​​preamble, and the terminal device can send the first information if N failures in sending the AI ​​preamble. Optionally, the terminal device can send the first information after entering the RRC connection state. Optionally, the terminal device can send the first information during the random access process, for example, in two-step random access, the terminal device sends the first information in the physical uplink shared channel (PUSCH), where the random access can be random access based on a non-AI preamble or random access based on an AI preamble.

[0175] Optionally, if the terminal device receives the second configuration information, and the second configuration information is specifically used to configure the terminal device to send the first information after entering the RRC connection state through the non-AI preamble after failing to send the AI ​​preamble N times, then if the first information is sent after failing to send the AI ​​preamble N times, it includes: the terminal device sends the first information after entering the RRC connection state through the non-AI preamble. That is, the terminal device attempts to send the AI ​​preamble, uses the AI ​​preamble for random access and enters the RRC connection state, but the AI ​​preamble may always fail to be sent, resulting in the terminal device being unable to enter the RRC connection state according to the AI ​​preamble. Therefore, the terminal device can send the first information after entering the RRC connection state through the non-AI preamble according to the second configuration information. Optionally, the non-AI preamble can be called a legacy preamble or a legacy preamble, etc., such as a preamble based on a ZC sequence or an m-sequence. Optionally, if the terminal device receives the second configuration information, and the second configuration information is specifically used to configure the terminal device to send the first information after entering the RRC connection state through the non-AI preamble after failing to send the AI ​​preamble for N consecutive times, then the terminal device sends the first information after entering the RRC connection state through the non-AI preamble after failing to send the AI ​​preamble for N consecutive times. That is to say, in the process of the terminal device attempting to use the AI ​​preamble for random access to enter the RRC connection state, when the number of failures reaches N times, the terminal device can fall back to using the non-AI preamble for random access, and send the first information after using the non-AI preamble for random access to enter the RRC connection state. Optionally, if the AI ​​preamble code that failed to be sent N times belongs to AI preamble code set 1, the terminal device can enter the RRC connection state through the first type of non-AI preamble code and send the first information; if the AI ​​preamble code that failed to be sent N times belongs to AI preamble code set 2, the terminal device can enter the RRC connection state through the second type of non-AI preamble code and send the first information, AI preamble code set 1 is different from AI preamble code set 2, and the intersection of AI preamble code set 1 and AI preamble code set 2 is empty, the first type is different from the second type, for example, the first type is NR formatC1 type, and the second type is NR formatC2 type, that is, if the AI ​​preamble code that failed to be sent belongs to a certain AI preamble code set, the terminal device can use the non-AI preamble code of the type corresponding to the AI ​​preamble code set to enter the RRC connection state.

[0176] Optionally, if a certain AI preamble code sent by the terminal device is successful, after successfully entering the RRC connection state using the AI ​​preamble code, the terminal device can also send the first information. That is, the terminal device can send the first information after entering the RRC connection state. The terminal device can enter the RRC connection state through the AI ​​preamble code, and can also enter the RRC connection state through the non-AI preamble code. The embodiment of the present application does not impose any limitation on the way in which the terminal device enters the RRC connection state.

[0177] Optionally, the network device may send a first request message to the terminal device, and the terminal device may receive the first request message from the network device, S320, including: in response to the first request message, the terminal device sends the first information to the network device according to the first configuration information, and the network device can receive the first information from the terminal device. That is, the terminal device may send the first information based on the request of the network device. Optionally, the terminal device may receive the first request message from the network device in an RRC connection state, and in response to the first request message, the terminal device sends the first information according to the first configuration information in the RRC connection state. For example, the first request information is indication information that the network device triggers the terminal device to send the first information. The network device may send the first request message through RRC signaling, MAC-CE signaling, or DCI signaling. After receiving the first request message, the terminal device sends the first information generated according to the first configuration information to the network device.

[0178] Optionally, the terminal device may send a second request message, the network device may receive the second request message, and after receiving the second request message, the network device may send a response message to the second request message to the terminal device, S320, including: the terminal device may send the first information to the network device based on the response message to the second request message according to the first configuration information, that is, the terminal device may actively request the network device to send the first information through the second request message, after the network device sends the response message to the second request message, it indicates that the network device has authorized the terminal device to send the first information, and the terminal device may send the first information to the network device based on the response message to the second request message. Optionally, the terminal device may send the second request message to the network device in the RRC connection state, the terminal device may also receive the response message to the second request message sent by the network device in the RRC connection state, and send the first information to the network device in the RRC connection state. For example, the second request message may be a Scheduling Request (SR) message, and the response message to the second request message may be uplink data transmission authorization information (UL grant) information. Optionally, the triggering condition for the terminal device to send the second request message can be determined by the second configuration information. For example, the second configuration information indicates that after the terminal device monitors N transmission failures, it can generate and send a second request message after entering the RRC connection state.

[0179] Optionally, after S320, the communication method 300 further includes: the network device performs AI model monitoring or AI model training based on the first information. For example, in the case of AI model monitoring, the network device compares whether the AI ​​preamble identifier is detected when performing AI preamble detection at the time point of the sending failure based on the identifier of the AI ​​preamble that failed to be sent and the time of the sending failure in the first information. If not detected, the network device may determine that there is a problem with the AI ​​preamble or the AI ​​preamble detection model, and then may deactivate the AI ​​preamble set to which the AI ​​preamble belongs, or replace the AI ​​preamble detection model. For example, in the case of AI model training, the network device uses the AI ​​preamble identifier as a label and the received signal as the input of the AI ​​detection model based on the AI ​​preamble identifier and the time of sending the AI ​​preamble in the first information, and in combination with the received signal at the time point of sending the AI ​​preamble, to train the AI ​​detection model.

[0180] Among them, the AI ​​model in the communication method 300 refers to the description of the AI ​​model in the communication method 200, and is not described in detail to avoid redundancy.

[0181] It should be noted that the above communication method 300 is described using a terminal device as an example. In some cases, the network device can send configuration information to multiple terminal devices to configure multiple terminal devices to monitor the information of sending AI preamble codes. The terminal device can send the information of sending AI preamble codes obtained by monitoring, and the network device can use the information sent by multiple terminal devices to monitor or train AI models.

[0182] In the above-mentioned communication method 300, the network device can send first configuration information to the terminal device to configure the terminal device to send information of the AI ​​preamble code. The terminal device can send first information based on the first configuration information from the network device. The first information includes information that the terminal device sends the AI ​​preamble code. The network device can perform AI model monitoring or AI model training based on the first information, thereby monitoring or training the AI ​​model for random access.

[0183] In some cases, after a terminal device fails to perform random access through an AI preamble, it can enter the RRC connected state through a non-AI preamble. The following is described in conjunction with the communication method 1000 in Figure 10. As shown in Figure 10, the communication method 1000 includes:

[0184] S1010, the network device sends first configuration information, and the terminal device receives the first configuration information. The first configuration information is used to configure the terminal device to send a non-AI preamble code after failing to send the AI ​​preamble code M times.

[0185] Optionally, S1010 includes: the network device may send the first configuration information via a broadcast message, and the terminal device may receive the first configuration information via a broadcast message.

[0186] Optionally, the communication method 1000 also includes: the terminal device sends an AI preamble code at least once, the network device can receive the AI ​​preamble code sent by the terminal device, if the network device receives the AI ​​preamble code sent by the terminal device at a certain time, the network device can send a response to the AI ​​preamble code to the terminal device, after the terminal device receives the response, it can be determined that the AI ​​preamble code is sent successfully; if the network device does not receive the AI ​​preamble code sent by the terminal device at a certain time, the network device will not send any response to the terminal device, and if the terminal device does not receive the response to the AI ​​preamble code within a preset time period, it can be determined that the AI ​​preamble code fails to be sent.

[0187] S1020: The terminal device sends a non-AI preamble code after failing to send the AI ​​preamble code M times according to the first configuration information.

[0188] Optionally, the non-AI preamble may be referred to as a legacy preamble or a traditional preamble, for example, a preamble based on a ZC sequence or an m-sequence.

[0189] Among them, the non-AI preamble code is used for random access.

[0190] Optionally, the non-AI preamble may be configured in the first configuration information. For example, the first configuration information indicates that the non-AI preamble is a non-AI preamble in a non-AI random access mode used by the current cell.

[0191] Optionally, the M failures in sending the AI ​​preamble may be M failures in sending the same AI preamble, or M failures in sending different AI preambles in total.

[0192] In the above-mentioned communication method 1000, when the terminal device sends the AI ​​preamble code M times without success, that is, the terminal device attempts to use the AI ​​preamble code for random access, until M attempts are unsuccessful, it means that it may not be possible to use the AI ​​preamble code for random access. Therefore, the terminal device can fall back to the non-AI preamble code and try to use the non-AI non-preamble code for random access to avoid the terminal device always using the AI ​​preamble code for random access, and the problems of wasted signaling or long access delay caused by the inability to access.

[0193] It should be noted that the first configuration information in the communication method 200, the first configuration information in the communication method 300 and the communication method 1000 have different meanings, and the second configuration information in the communication method 200 and the second configuration information in the communication method 300 also have different meanings.
