Communication method and communication apparatus

[0001] The present application claims priority to the Chinese Patent Application No. 202410464755.0, filed on April 16, 2024, and entitled "A communication method and communication apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, and in particular, to a communication method and communication apparatus. BACKGROUND

[0003] Currently, wireless local area network (WLAN) sensing refers to using wireless signals received from a station (STA) with WLAN sensing capability to determine the characteristics (such as range, speed, angle, motion, presence or proximity, posture, etc.) of an intended target (such as a target object, a human or an animal, etc.) in a given environment (such as a room, a house, a vehicle, or an enterprise, etc.). Both the access point station (AP STA) and the non-AP STA can collect sensing-related information when performing sensing. Different WLAN sensing methods are mainly divided into two categories: low-frequency sensing (such as sub-7 gigahertz (Sub-7GHz)) and directional multi-gigabit (DMG, such as 60GHz) sensing. The power consumption and application scenarios corresponding to different sensing frequencies are also different. Therefore, how to switch different sensing frequencies in different application scenarios to improve user experience becomes a problem to be solved. SUMMARY

[0004] The present application provides a communication method and communication apparatus, which is beneficial to switching sensing frequencies for sensing devices and improving energy efficiency.

[0005] In a first aspect, the present application provides a communication method, which is applied to a first device, for example, the method can be executed by the first device. For example, the first device can be a network management device (such as an access network controller, a network management service provider, an optical terminal device, or a master optical network unit, etc.), or a component (such as a processor, a chip, or a chip system, etc.) of the network management device, or a logic module capable of implementing all or part of the network management function. Wherein the first device receives first environment information from a sensing device, and according to the first environment information, sends first information to the sensing device; wherein the first information includes a first sensing frequency.

[0006] In the method, the first device can receive first environment information from the sensing device, determine a sensing frequency that can be used by the sensing device based on the first environment information, and send first information to the sensing device, thereby indicating the first sensing frequency to the sensing device, facilitating the sensing device to switch the sensing frequency and improving energy efficiency.

[0007] In a possible implementation, the first device receives second environment information from the sensing device, and sends second information to the sensing device according to the second environment information; the second information includes a second sensing frequency; and the second sensing frequency is different from the first sensing frequency.

[0008] In the implementation, the first device can further receive second environment information from the sensing device, and determine whether the sensing device needs to switch the sensing mode based on a difference between the second environment information and the first environment information. For example, it is assumed that the sensing device currently uses the first sensing frequency for sensing, and the first sensing frequency is a high frequency (e.g., 60 GHz); if the first device determines, according to the second environment information, that the second sensing frequency is a low frequency (e.g., 7 GHz), the first device sends the second information to the sensing device, thereby indicating the second sensing frequency to the sensing device, so that the sensing device switches from the first sensing frequency to the second sensing frequency, facilitating the sensing device to improve energy efficiency.

[0009] In a possible implementation, the first environment information includes channel state information data.

[0011] In a possible implementation, the first environment information has a corresponding relationship with the first sensing frequency.

[0012] In the above implementation, it is assumed that the first environment information has a corresponding relationship with the first sensing frequency, for example, the channel state information data has a corresponding relationship with the sensing frequency, or the frequency band information and the channel state information data have a corresponding relationship with the sensing frequency, thereby facilitating the first device to determine the corresponding first sensing frequency based on the first environment information.

[0013] In a possible implementation, the first device predicts user behavior based on the first environment information. The first device determines the first sensing frequency based on the user behavior.

The first device generates a correspondence between the third environment information and the user behavior based on the training information.

[0016] In the above implementation, the first device can predict the user behavior based on the first environment information, and determine the first sensing frequency. For example, the first device can first receive training information comprising third environment information and user behavior, wherein the third environment information comprises environment information collected by the sensing device before the current time, and is used for training of the first device to generate a correspondence between the third environment information and the user behavior. The first device can match the first environment information with the correspondence between the third environment information and the user behavior, for example, obtain third environment information closest to the first environment information, to determine the corresponding user behavior, and thus determine the first sensing frequency.

[0017] In a possible implementation, the first information further comprises a reporting period of the environment information.

[0018] In this implementation, the first device can further indicate the reporting period of the environment information to the sensing device, which facilitates the sensing device to send the environment information again (for example, send the second environment information).

[0019] In a second aspect, a communication method is provided. The method is applied to a second device, for example, the method can be performed by the second device. For example, the second device can be a sensing device (such as an AP STA, a non-AP STA, an optical network unit, or an edge optical network unit), or a component (such as a processor, a chip, or a chip system) of the sensing device, or a logic module capable of implementing all or part of the sensing function. In the method, the second device sends first environment information, and receives first information comprising a first sensing frequency. The second device performs sensing by using the first sensing frequency.

[0020] In the method, the second device can send the first environment information to the first device, which facilitates the first device to determine the first sensing frequency based on the first environment information, and send the first information to the second device. After receiving the first information, the second device can obtain the first sensing frequency, to determine whether to switch the sensing frequency, and improve the energy efficiency.

[0021] In a possible implementation, the second device sends second environment information. The second device receives second information comprising a second sensing frequency, the second sensing frequency being different from the first sensing frequency. The second device performs sensing by using the second sensing frequency.

[0022] In the embodiment, the second device can further send the second environment information, which is beneficial for the first device to determine whether the sensing device needs to switch the sensing mode based on the difference between the second environment information and the first environment information. For example, it is assumed that the second device currently adopts the first sensing frequency for sensing, and it is assumed that the first sensing frequency is a high frequency (e.g., 60 GHz); if the first device determines that the second sensing frequency is a low frequency (e.g., 7 GHz) according to the second environment information, the first device sends the second information to the second device, so as to indicate the second sensing frequency to the second device. Therefore, the second device can switch from the first sensing frequency to the second sensing frequency, and perform sensing by using the second sensing frequency, which is beneficial for improving the energy efficiency.

[0027] In a possible implementation, the second device sends training information, and the training information includes third environment information and user behavior.

[0028] In the embodiment, the second device can send the training information to the first device, so that the first device performs training based on the training information to obtain a corresponding relationship between the third environment information and the user behavior, and the corresponding relationship is used by the first device to predict the user behavior, which is beneficial for determining the first sensing frequency.

[0029] In a possible implementation, the first information further includes a reporting period of the environment information.

[0030] In a possible implementation, the second device sends the environment information to the first device by using the reporting period.

[0031] In the above embodiment, the second device can further receive the reporting period of the environment information, which is beneficial for the second device to send the environment information (e.g., the second environment information) again based on the reporting period, so as to be beneficial for the first device to determine whether to adjust the sensing frequency of the second device.

[0056] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0057] For ease of understanding, the definitions of related terms involved in the present application are described in detail as follows:

[0058] 1. Network architecture: For example, the communication method provided by the present application can be applied to the network architecture as shown in FIG. 1. The network architecture shown in FIG. 1 includes network management and sensing devices (such as AP STA or non-AP STA shown in FIG. 1). It can be understood that FIG. 1 is only an example, and only part of the devices are shown (for example, more sensing devices can also be included, the form of the sensing devices can not be limited to the form shown in the figure, etc.), and the present application does not limit the network architecture to which the communication method is applied.

[0059] Among them, the communication method provided by the present application can be applied to a mobile communication system. For example: the mobile communication system can be a fourth generation (4th generation, 4G) communication system (for example, a long term evolution (long term evolution, LTE) system), a worldwide interoperability for microwave access (worldwide interoperability for microwave access, WiMAX) communication system, a wireless local area network (wireless local area networks, WLAN), a fifth generation (5th generation, 5G) communication system (for example, a new radio (new radio, NR) system), and a future mobile communication system, etc.; it can also be applied to satellite communication systems, high altitude platform (high altitude platform station, HAPS) communication, unmanned aerial vehicle NTN systems, such as integrated communication and navigation (integrated communication and navigation, IcaN) systems, global navigation satellite systems (global navigation satellite system, GNSS) and ultra-dense low-orbit satellite communication systems, etc.

[0062] Optionally, the AP STA can be a network device such as a base station, which is a device with wireless transceiving functions and is used to communicate with a terminal device. For example, the network device is a radio access network (RAN) node that accesses a terminal device to a wireless network. In this application, the network device can include, but is not limited to, an evolved node B (eNB), 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), or a transmission reception point (TRP), and the like.

In addition, the network device can also be a network node constituting a gNB or a TP, such as a BBU, a distributed unit (DU), and the like. Alternatively, the network device can also be a device that undertakes a network side function in a device-to-device (D2D) communication system, a machine to machine (M2M) communication system, an Internet of Things (IoT), a vehicle-to-vehicle communication system, or other communication systems, a satellite, and the like.

[0063] Optionally, the non-AP STA can be a terminal, which is a device with wireless transceiver function, and can send signals to network devices or receive signals from network devices. The terminal mentioned in the present application includes various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to wireless modems with wireless communication functions, and can specifically refer to user equipment (UE), 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 functions of the terminal can also be performed by a module (such as a chip or modem) in the terminal, or by a device containing the functions of the terminal.

[0066] 2. WLAN sensing:

[0067] WLAN sensing refers to using wireless signals received from a STA with WLAN sensing capability to determine the characteristics (such as range, speed, angle, motion, presence or proximity, and posture) of intended targets (such as objects, humans, and animals) in a given environment (such as a room, a house, a vehicle, and an enterprise). The IEEE 802.11bf working group currently classifies WLAN sensing into several categories, including: indoor sensing, posture recognition, health monitoring, 3D vision, in-vehicle sensing, etc. For example, indoor sensing refers to determining events occurring indoors, counting the number of people, etc. through WLAN sensing. Posture recognition refers to recognizing consumers or determining consumer needs, etc. through WLAN sensing posture. Health monitoring refers to measuring heart rate and respiration, etc. and using WLAN for monitoring. 3D vision refers to forming a three-dimensional view through WLAN sensing data. In-vehicle sensing refers to detecting in-vehicle personnel behavior to avoid high-risk driving behavior through WLAN sensing.

[0068] Among them, the sensing process is generally realized by the interaction between the AP STA (such as a Wi-Fi device, etc.) and the Non-AP STA (such as a mobile phone, etc.). For example, the AP STA and the Non-AP STA can both act as a data packet receiver (RX) and a data packet transmitter (TX) when performing sensing. The data exchanged between the two parties can be channel state information (CSI) data. That is, the AP STA and the Non-AP STA can both act as CSI data acquirers and analyze the CSI data to obtain sensing results. In one possible implementation, the AP STA or the Non-AP STA can also complete sensing through back wave alone. That is, the AP STA or the Non-AP STA can transmit a signal and receive the back wave of the signal, and analyze the CSI data to obtain the sensing result; single-STA sensing through back wave is more flexible and convenient. In another possible implementation, the AP STA and the Non-AP STA can perform cooperative sensing, which has higher accuracy.

[0069] IEEE 802.11bf working group specifies different WLAN sensing modes, mainly divided into two categories: low frequency band sensing (such as Sub-7GHz) and DMG (such as 60GHz) sensing. Different sensing modes are applied in different scenarios, for example, in general, Sub-7GHz is suitable for scenarios that require larger coverage, larger targets and detection. DMG is suitable for applications that require smaller coverage, smaller targets and fine motion.

[0070] Different WLAN sensing modes have different power consumptions, for example: DMG sensing mode uses higher frequency (60GHz), resulting in higher path loss, thus increasing energy consumption. Although DMG sensing has higher accuracy, many application scenarios do not require ultra-high precision sensing; for example, if the application scenario is to count the number of people, determine the position, etc. without the need for high-precision sensing, the sensing device can use Sub-7GHz sensing mode; and in health observation or gesture recognition scenarios that require high-precision sensing, the sensing device uses DMG sensing. Using DMG mode for sensing can obtain greater accuracy, but the power consumption is very large; if the sensing mode is not switched in time in scenarios that do not require sensing accuracy, it will increase energy consumption and affect user experience. In order to solve the above problems, the present application provides a communication method, which uses a network management device to switch the WLAN sensing mode, which is beneficial to improve the energy efficiency of the sensing device.

[0071] For example, FIG. 2 is a flowchart of a communication method provided by the present application. The method is realized by the interaction between the first device and the second device, wherein the first device can be a network management device, such as an AN controller, a network management service provider, an OLT or a P-ONU, etc., and the second device can be a sensing device, such as an AP STA, a non-AP STA, an ONU or an E-ONU, etc. The method includes the following steps:

[0072] S101, the second device sends first environment information; correspondingly, the first device receives the first environment information.

[0073] The first environment information can be used to represent the current environment of the second device, which can be the information of the current environment collected by the second device; for example, the second device can collect the information of the current environment through sensing. Assuming that the current time is the first time, the first environment information is the environment information corresponding to the first time.

[0074] Optionally, the method further comprises: the second device sending second environment information; and correspondingly, the first device receiving the second environment information. The second environment information is environment information corresponding to a second time point. For example, the current time point is the second time point, and the second device can collect information of the current environment through sensing. The second time point can be a time point next to the first time point. For example, after sending the first environment information, the second device sends the second environment information after a period of time or after receiving an indication from the first device. Optionally, the indication from the first device is an indication that the first device can directly instruct the second device to send environment information (for example, instruct the second device to send the second environment information), without waiting for a period of time.

[0075] In this case, because the wireless channel between the first device and the second device can change, the second environment information and the first environment information can be different environment information.

[0076] The first environment information or the second environment information can be used to measure the sensing frequency switching of the sensing device, for example, to measure whether the sensing device needs to switch the sensing frequency.

[0077] In a possible implementation, the environment information includes channel state information data. For example, assuming that the second device is an AP STA, and assuming that the AP STA is a data receiver, the AP STA can collect CSI data, which is CSI data between the AP STA and a non-AP STA (for example, transmission path data, signal strength data, and the like between the AP STA and the non-AP STA). For another example, assuming that the second device is a non-AP STA, and assuming that the non-AP STA is a data receiver, the non-AP STA can collect CSI data, which is CSI data between the AP STA and the non-AP STA. It can be understood that the first environment information and the second environment information both include CSI data, but the CSI data in the first environment information and the CSI data in the second environment information can be different.

[0078] In a possible implementation, the environment information includes frequency band information. For example, assuming that the second device is an AP STA, and assuming that the AP STA is a data receiver, the AP STA can collect frequency band information, which includes a frequency band in which the AP STA receives data. For another example, assuming that the second device is a non-AP STA, and assuming that the non-AP STA is a data receiver, the non-AP STA can collect frequency band information.

[0079] Optionally, there is an association relationship between the CSI data and the frequency band information. For example, the higher the frequency band used by the sensing device, the more accurate data the sensing device can collect, and the more accurate the CSI data is.

[0080] In a possible implementation, the second device sends the first environment information, which can be sent directly to the first device or forwarded to the first device through other devices. For example, assuming that the second device is an AP STA, the AP STA can directly send the first environment information to the network management device. For another example, assuming that the second device is a non-AP STA, since the non-AP STA cannot directly send the first environment information to the network management device, the non-AP STA can send the first environment information to the AP STA, and the AP STA forwards the first environment information to the network management device (for example, the AP STA can transparently transmit the first environment information). Optionally, the second device sends the second environment information in a similar manner, for example, the AP STA can directly send the second environment information to the network management device, or the non-AP STA can transparently transmit the second environment information through the AP STA, which is not limited in the present application.

[0081] S102, the first device sends first information to the second device according to the first environment information.

[0082] The first information can include the first sensing frequency.

[0083] The first device can determine the sensing frequency that can be used by the second device according to the first environment information, for example, the first sensing frequency. The first device can send the first information to the second device, so as to indicate the first sensing frequency to the second device.

[0084] In a possible implementation, the first device can determine the CSI data, frequency band information, and the like in the first environment information according to the first environment information. Assuming that the first device is preconfigured with a group of CSI data and user behaviors corresponding to the CSI data, the first device can compare the CSI data in the first environment information with the preconfigured CSI data, determine the user behavior corresponding to the CSI data in the first environment information, and determine the first sensing frequency that can be used by the second device for the user behavior. For example, assuming that the user behavior is a user behavior with high accuracy requirement, the second device can use a high frequency for sensing (i.e., the first sensing frequency is a high frequency).

[0085] Optionally, if the first device also receives the second environment information, the above method further includes: the first device determines to switch the sensing frequency to a second sensing frequency according to the second environment information, or determines that the second device needs to switch the sensing frequency according to the second environment information; further, the first device sends second information to the second device to instruct the second device to switch to the second sensing frequency. The second sensing frequency is different from the first sensing frequency.

[0086] In a possible implementation, the first information includes a first sensing frequency. For example, the first device sends the first information to the second device, and the first information includes the first sensing frequency, so as to directly indicate to the second device that the sensing frequency that can be adopted by the second device is the first sensing frequency. The first sensing frequency can be a DMG sensing frequency (e.g., 60 GHz) or a low-band sensing frequency (e.g., Sub-7 GHz). Alternatively, the first information can also be indication information for indicating the first sensing frequency. For example, assuming that the first information is 1-bit indication information, when the bit is 0, it is used to indicate that the first sensing frequency is a DMG sensing frequency; and when the bit is 1, it is used to indicate that the first sensing frequency is a low-band sensing frequency.

[0087] In a possible implementation, the first information further includes a reporting period of the environment information. For example, the environment information can be periodic information that is reported according to a reporting period. For example, the second device sends first environment information to the first device, and after a reporting period, the second device sends second environment information to the first device. Alternatively, the first device can adjust the reporting period of the environment information, and indicate the adjusted reporting period of the environment information to the second device through the first information. For example, assuming that in a first time period, the second device sends the first environment information according to a first reporting period; if the first device determines that the reporting frequency of the environment information can be reduced (that is, the reporting period is increased), the first device further includes a second reporting period (e.g., the second reporting period is greater than the first reporting period) in the first information sent to the second device. Correspondingly, after receiving the first information, the second device sends the second environment information according to the second reporting period.

[0088] In this embodiment, the first device can receive the environment information (e.g., the first environment information or the second environment information) from the second device, and determine the sensing frequency that can be adopted by the second device based on the environment information. The first device indicates the sensing frequency (e.g., the first sensing frequency or the second sensing frequency) to the second device, which is beneficial to the second device to switch the sensing frequency in time and improve energy efficiency.

[0089] In an example, the present application provides a communication method, which can be divided into two stages, for example, a training stage and a use stage. In the training stage, the first device receives training information (which can include environment information for training) from the second device, and generates a correspondence between the environment information and user behavior based on the training information. In the use stage, the first device receives environment information from the second device, and determines the user behavior based on the environment information and the correspondence between the environment information and the user behavior generated in the training stage, so as to determine the sensing frequency. The following takes FIG. 3 to FIG. 5 as examples for illustration.

[0090] FIG. 3 is a flow diagram of another communication method provided by the present application. The method is implemented by interaction between a first device and a second device. For example, the first device can be a network management device, such as an AN controller, a network management service provider, an OLT, or a P-ONU, etc., and the second device can be a sensing device, such as an AP STA, a non-AP STA, an ONU, or an E-ONU, etc. The method includes the following steps:

[0091] S201. The second device sends training information. Correspondingly, the first device receives the training information.

[0092] The training information can include at least one of third environment information and user behavior.

[0093] The third environment information can be historical environment information collected by the second device. For example, the second device can continuously collect environment information (such as channel state information data, frequency band information) during sensing and record the collected environment information.

[0094] The user behavior refers to the number of users, the posture, gestures, health information, face information, or body information of the user, etc., which can be detected by the second device through sensing. For example, WLAN sensing can realize in-vehicle sensing, and the user behavior can refer to the driving posture and gestures of the user in the vehicle.

[0095] Optionally, the training information further includes frequency band information and time information. The frequency band information can refer to the corresponding description in the foregoing embodiments, for example, the frequency band information refers to the frequency band of the data received by the second device, which will not be described here. The time information refers to the time when the user behavior occurs, for example, the second device records the user behavior and also records the time information corresponding to the user behavior.

[0096] S202. The first device generates a corresponding relationship between the third environment information and the user behavior based on the training information.

[0097] The corresponding relationship between the third environment information and the user behavior means that there is a corresponding relationship between the third environment information and the user behavior. For example, if a specific user behavior corresponds to a set of environment information (such as corresponding CSI data, specific frequency band, etc.), the first device generates a corresponding relationship between the third environment information and the user behavior based on the training information.

[0098] In one possible implementation, the corresponding relationship between the third environment information and the user behavior can be a corresponding relationship between CSI data and user behavior. For example, Table 1 shows the corresponding relationship between CSI data and user behavior.

[0099] Table 1: Corresponding relationship between CSI data and user behavior.

[0100] For example, based on Table 1, the first apparatus can determine the user behavior based on the CSI data.

[0101] In a possible implementation, assuming that the third environment information is CSI data and frequency band information, the correspondence between the third environment information and the user behavior can specifically be the correspondence between the CSI data, the frequency band information, and the user behavior. For example, Table 2 is the correspondence between the CSI data, the frequency band information, and the user behavior.

[0102] Table 2: Correspondence between CSI data, frequency band information, and user behavior.

[0103] For example, based on Table 2, the first apparatus can determine the user behavior based on the CSI data and the frequency band information.

[0104] In a possible implementation, the correspondence between the third environment information and the user behavior can specifically be the correspondence between the CSI data, the frequency band information, and the user behavior, and time information. For example, Table 3 is the correspondence between the CSI data, the frequency band information, the user behavior, and the time information.

[0105] Table 3: Correspondence between CSI data, frequency band information, user behavior, and time information.

[0106] For example, based on Table 3, the first apparatus can determine the user behavior and the time of occurrence based on the CSI data and the frequency band information.

[0107] S203, the second apparatus sends the first environment information; correspondingly, the first apparatus receives the first environment information.

[0108] The specific implementation of S203 can refer to the corresponding description in S101, and details are not described herein.

[0109] S204, the first apparatus predicts the user behavior based on the first environment information.

[0110] In a possible implementation, the first apparatus determines the user behavior based on the first environment information, and the correspondence between the third environment information and the user behavior. For example, assuming that the first environment information includes first CSI data, and assuming that the correspondence between the third environment information and the user behavior is shown in Table 1, the first apparatus can derive the user behavior corresponding to the first CSI data through Table 1.

[0111] Optionally, if the correspondence between the third environment information and the user behavior does not include the first environment information, the first device can compare the first environment information with the environment information in the correspondence, and perform prediction and derivation based on the related model to obtain the user behavior corresponding to the first environment information. For example, it is assumed that the first environment information includes first CSI data, and it is assumed that the correspondence between the third environment information and the user behavior does not include the first CSI data; the first device can compare the first CSI data with the CSI data in the correspondence between the third environment information and the user behavior. For example, it is assumed that the first CSI data is represented by a vector, that is, the first CSI data corresponds to a first vector, and it is assumed that the CSI data in the correspondence between the third environment information and the user behavior is also represented by a vector; the first device can compare (for example, compare the vector similarity) the first vector and the vector corresponding to the CSI data in the correspondence, determine the vector (referred to as a second vector for example) in the correspondence with the highest vector similarity, and predict the user behavior based on the second vector and the related model (such as a Bayesian network / hidden Markov model (HMM) and the like) to determine the user behavior corresponding to the first CSI data.

[0112] In S205, the first device determines the first sensing frequency based on the user behavior.

[0113] In a possible implementation, there is a correspondence between the user behavior and the sensing frequency. For example, the user behavior can reflect the current WLAN sensing being performed, such as when the user behavior is that the user turns on the air conditioner by a gesture, which indicates that the current sensing device can perform gesture recognition. This WLAN sensing can use DMG sensing to implement applications of smaller targets and fine motions (such as user gestures), that is, the user behavior corresponds to a high frequency, such as a first sensing frequency of 60 GHz. For another example, when the user behavior is to count the number of people in a room, which indicates that the current sensing device can perform presence detection. This WLAN sensing can use low-frequency sensing to implement applications of larger targets and presence detection, that is, the user behavior corresponds to a low frequency, such as a first sensing frequency of 6 GHz. Therefore, based on the correspondence between the user behavior and the sensing frequency described above, after the first device predicts the user behavior based on the operation of S204, the first device can determine the first sensing frequency based on the user behavior and the correspondence between the user behavior and the sensing frequency.

[0114] In a possible implementation, a same sensing frequency corresponds to a same type of user behavior. For example, it is assumed that the first device predefines that a same sensing frequency corresponds to a same type of user behavior. For example, it is assumed that a same type of user behavior includes gesture recognition and in-vehicle sensing, and this type of user behavior is used for applications of smaller targets and fine motions by using DMG sensing, that is, this type of user behavior corresponds to a high frequency. When the user behavior belongs to this type of user behavior, the first device can determine that the first sensing frequency is the high frequency, and / or when the user behavior does not belong to this type of user behavior, the first device can determine that the first sensing frequency is a low frequency.

[0115] Optionally, when the first device receives the second environment information, the first device can also perform similar steps to determine the second sensing frequency. For example, the first device can predict the user behavior based on the second environment information, and determine the second sensing frequency based on the user behavior, and then send second information including the second sensing frequency. For details, refer to the corresponding description of S204 and S205, which will not be repeated here.

[0116] S206, the first device sends the first information; and correspondingly, the second device receives the first information.

[0117] For details of S206, refer to the corresponding description of S102, which will not be repeated here.

[0118] Based on the method shown in FIG. 3, the first device receives training information, and generates a corresponding relationship between environment information and user behavior based on the training information; then predicts the user behavior based on the environment information and the corresponding relationship, and further determines the sensing frequency. Further, the first device indicates the first sensing frequency to the second device, so that the second device switches the sensing frequency based on the first sensing frequency; for example, it is assumed that the second device previously uses a high frequency for sensing, if the first sensing frequency is a low frequency, the second device can switch from the high frequency to the low frequency for sensing, which is beneficial to reduce power consumption, thereby improving energy efficiency.

[0119] The following will describe in detail the specific implementation of the communication method provided by the present application when applied to different devices.

[0120] Example one: under the unified management of an access network, the access network is managed by an AN controller. For example, the form of the AN controller can be an OLT or a network management service provider. The sensing device can include a Non-AP STA and an ONU. For example, FIG. 4 is a flowchart of a communication method provided by the present application applied to an AN controller, a Non-AP STA and an ONU, which includes the following steps:

[0121] S301a, the Non-AP STA sends training information; correspondingly, the AN controller receives the training information.

[0122] S301b, the ONU sends training information; correspondingly, the AN controller receives the training information.

[0123] For example, the Non-AP STA sends training information to the AN controller, specifically, the Non-AP STA can send training information to the AN controller through the AP STA. Optionally, the AP STA can transparently transmit the training information without processing.

[0124] For example, the ONU can directly send training information to the AN controller.

[0125] Optionally, the specific description of the training information can refer to the description of the training information in the foregoing embodiments, which will not be described here.

[0126] Optionally, the execution order of S301a and S301b is not limited in the present application, for example, S301a can be executed first and then S301b is executed, or S301b can be executed first and then S301a is executed, or S301a and S301b can be executed simultaneously, which can be regarded as parallel steps.

[0127] S302, the AN controller generates a corresponding relationship between the third environment information and the user behavior based on the training information.

[0128] For example, the AN controller forms a fingerprint library based on the training information. The fingerprint library mainly stores the specific behavior of the user and the corresponding frequency band and CSI data, and the possible time. For example, Tables 1-3 described in the foregoing embodiments can be regarded as the fingerprint library.

[0129] S303a, the Non-AP STA sends first environment information; correspondingly, the AN controller receives the first environment information.

[0130] S303b, the ONU sends first environment information; correspondingly, the AN controller receives the first environment information.

[0131] For example, the Non-AP STA / ONU sends first environment information (such as CSI data and / or frequency band information) to the AN controller, and the first environment information is used to measure whether switching sensing mode is needed.

[0132] Optionally, the specific description of the first environment information can refer to the description of the first environment information in the foregoing embodiments, which will not be described here.

[0134] S304, the AN controller predicts the user behavior based on the first environment information and the fingerprint library.

[0135] S305, the AN controller determines the first sensing frequency based on the user behavior.

[0136] For example, the AN controller predicts the next user behavior according to the fingerprint library and the current environment (such as CSI data and / or frequency band information), and judges whether to switch the sensing mode. Specifically, the AN controller can compare the current CSI data with the CSI data in the fingerprint library, predict the next user behavior, and determine whether to switch the sensing mode (such as switching the sensing frequency).

[0137] Optionally, the specific description of the user behavior and the first sensing frequency can refer to the corresponding description in the foregoing embodiments, which will not be described here.

[0138] S306a, the AN controller sends the first information; correspondingly, the ONU receives the first information.

[0139] S306b, the AN controller sends the first information; correspondingly, the Non-AP STA receives the first information.

[0140] For example, the AN controller sends the first sensing frequency to the Non-AP STA / ONU, and can also send the first time interval.

[0141] Optionally, the specific description of the first information can refer to the description of the first information in the foregoing embodiments, which will not be described here.

[0142] Optionally, the execution order of S306a and S306b is not limited in the present application, for example, S306a can be executed first and then S306b, or S306b can be executed first and then S306a, or S306a and S306b can be executed simultaneously, both of which can be regarded as parallel steps.

[0143] Example 2: In the optical access network, the management is performed by the P-ONU. For example, the network management device is the P-ONU. The sensing device can include the Non-AP STA and the E-ONU. For example, FIG. 5 is a flowchart of a communication method provided by the present application applied to the P-ONU, the Non-AP STA, and the E-ONU, and the flowchart includes the following steps:

[0144] S401a, the Non-AP STA sends training information; correspondingly, the P-ONU receives the training information.

[0145] S401b, the E-ONU sends training information; correspondingly, the P-ONU receives the training information.

[0146] For example, the Non-AP STA sends the training information to the P-ONU, and specifically, the Non-AP STA can send the training information to the P-ONU through the AP STA. Optionally, the AP STA can transparently transmit the training information without processing.

[0147] For example, the E-ONU can directly send the training information to the P-ONU.

[0148] Optionally, the specific description of the training information can refer to the description of the training information in the foregoing embodiments, which will not be described here.

[0149] Optionally, the execution order of S401a and S401b is not limited by the present application, for example, S401a can be executed first and then S401b is executed, or S401b can be executed first and then S401a is executed, or S401a and S401b can be executed simultaneously, which can be regarded as parallel steps.

[0150] S402, the P-ONU generates a corresponding relationship between the third environment information and the user behavior based on the training information.

[0151] For example, the P-ONU forms a fingerprint library based on the training information. The fingerprint library mainly stores the specific behavior of the user, the corresponding frequency band and CSI data, and the possible time. For example, Tables 1-4 described in the foregoing embodiments can be regarded as the fingerprint library.

[0152] S403a, the Non-AP STA sends first environment information; correspondingly, the P-ONU receives the first environment information.

[0153] S403b, the E-ONU sends first environment information; correspondingly, the P-ONU receives the first environment information.

[0154] For example, the Non-AP STA / E-ONU sends first environment information (such as CSI data and / or frequency band information) to the P-ONU, and the first environment information is used to measure whether switching sensing mode is needed.

[0155] Optionally, the specific description of the first environment information can refer to the description of the first environment information in the foregoing embodiments, and will not be described here again.

[0156] Optionally, the execution order of S403a and S403b is not limited in the present application, for example, S403a can be executed first and then S403b is executed, or S403b can be executed first and then S403a is executed, or S403a and S403b can be executed simultaneously, and the two can be regarded as parallel steps.

[0157] S404, the P-ONU predicts user behavior based on the first environment information and the fingerprint library.

[0158] S405, the P-ONU determines a first sensing frequency based on the user behavior.

[0159] For example, the P-ONU predicts the next behavior of the user according to the fingerprint library and the current environment (such as CSI data and / or frequency band information), and judges whether to switch the sensing mode. Specifically, the P-ONU can compare the current CSI data with the CSI data in the fingerprint library, predict the next user behavior, and determine whether to switch the sensing mode (such as switching the sensing frequency).

[0160] Optionally, the specific description of the user behavior and the first sensing frequency can refer to the corresponding description in the foregoing embodiments, and will not be described here again.

[0161] S406a, the P-ONU sends first information; correspondingly, the E-ONU receives the first information.

[0162] S406b, the P-ONU sends first information; correspondingly, the Non-AP STA receives the first information.

[0163] For example, the P-ONU sends the first sensing frequency to the Non-AP STA / E-ONU, and can also send a first time interval.

[0164] Optionally, the specific description of the first information can refer to the description of the first information in the foregoing embodiments, and will not be described here again.

[0165] Optionally, the execution order of S406a and S406b is not limited in the present application, for example, S406a can be executed first and then S406b is executed, or S406b can be executed first and then S406a is executed, or S406a and S406b can be executed simultaneously, and the two can be regarded as parallel steps.

[0166] As can be seen, in the two examples above, the network management device can form a fingerprint library according to the training information. The fingerprint library mainly stores specific habits of the user at specific times and corresponding CSI data and the like. Moreover, the network management device can determine whether to switch the sensing mode according to the recorded fingerprint library and the current environment information, and issue a sensing strategy to the Non-AP STA and the ONU and the like, so as to instruct the Non-AP STA and the ONU and the like whether to switch the sensing frequency, which is beneficial to improving the energy efficiency.
