[0054] With the development of wireless sensing technology, wireless communication tends to develop towards the integration of communication and sensing, that is, integrating the two functions of communication and sensing, so that the communication system has both communication and sensing functions at the same time. While transmitting information over the wireless channel, by actively recognizing and analyzing the characteristics of the channel, the physical characteristics of the surrounding environment can be sensed, enabling the communication and sensing functions to enhance each other. For example, based on the wireless communication between the terminal and the communication area, when the wireless sensing function is enabled at the terminal, the user can use various actions to achieve the experience of human behavior sensing.

[0055] Figure 1 The figure shows a flowchart of a communication area switching method according to an embodiment of the present application. A communication area switching method provided by an embodiment of the present application is as follows Figure 1 shown and includes:

[0056] S100, in response to an instruction to switch the communication area, obtain the communication parameters of the candidate communication areas;

[0057] The communication area switching method of this embodiment is applied to the field of wireless communication. For example, in the scenario of 6G wireless communication, a user performs wireless communication with a base station corresponding to the communication area through a local device. As Figure 5 shown, in the case of having a sensing requirement in the current wireless communication environment, the communication area of the local end can be switched to a communication area that simultaneously meets the communication requirement and the sensing requirement. The local end can be a local device used by the user, and the target object to be sensed can be between the local end and the communication device corresponding to the communication area. The communication signal sent by the communication device corresponding to the communication area, after being reflected or diffracted by the target object, is then obtained by the local end to obtain the change of the communication signal, and the target object can be sensed. The communication signal can be a CSI (Channel State Information) signal, and the target object can be a human body or a moving object. In the case of needing to switch to a communication area that meets the sensing condition and the communication condition, for example, in the case of the target object moving and needing to switch the communication area, or in the case that the current communication area does not meet the communication condition of the terminal, or in the case of needing to perform wireless sensing in the current wireless communication environment that does not support wireless sensing, it indicates that the current communication area needs to be switched. Based on the current requirement for wireless sensing or wireless communication, an instruction to switch the communication area can be generated, and the instruction to switch the communication area can be given to the local end. In response to the instruction to switch the communication area, the local end obtains the communication parameters of the candidate communication areas, and selects a communication area that meets the sensing condition and the communication condition from the candidate communication areas according to the communication parameters of the candidate communication areas. The communication parameters include wireless communication related parameters and wireless sensing related parameters. For example, the communication parameters can include the distance between the device corresponding to the communication area and the local end, and the frequency points supported by the wireless sensing of the communication area.

[0058] S200, determine the target communication area in the candidate communication areas whose communication parameters meet the sensing condition and the communication condition;

[0059] In this embodiment, after obtaining the communication parameters of the candidate communication areas, the target communication area whose communication parameters meet the sensing condition and the communication condition is determined from the candidate communication areas according to the communication parameters of the candidate communication areas; the sensing condition indicates that the communication parameters can be used to sense the actions of the target object at the target amplitude; the communication condition indicates that the communication parameters can be used for communication of the target quality. In different wireless sensing scenarios, the target amplitude of the actions made by the target object is different. The communication area that meets the sensing condition can be determined according to the specific wireless sensing scenario. For example, if the current sensing scenario is respiration sensing, the target amplitude of the actions corresponding to respiration sensing can be set to "1-2 cm", and the communication area that meets the respiration sensing condition can be determined according to the target amplitude of the actions corresponding to respiration sensing, that is, the communication area whose communication parameters can be used for the actions at the target amplitude corresponding to respiration sensing is selected; or, if the current sensing scenario is gesture sensing, the target amplitude of the actions corresponding to gesture sensing can be set to "40-60 cm", and the communication area that meets the gesture sensing condition can be determined according to the target amplitude of the actions corresponding to gesture sensing, that is, the communication area whose communication parameters can be used for the actions at the target amplitude corresponding to gesture sensing is selected. After determining the communication area that meets the sensing condition, the communication area that meets the target communication quality can be further selected from the communication areas that meet the sensing condition. For example, the communication area that meets the communication condition can be selected by the S criterion (Selection Criterion) and the R criterion (Rank Criterion). The S criterion can be used for signal strength evaluation in the process of communication area selection and reselection. Based on the S criterion, the signal strength of the candidate communication area (such as RSRP, Reference Signal Received Power) can be determined. When the signal strength value of a certain candidate communication area meets a certain threshold, it indicates that the signal transmission quality of this communication area is good and can meet the communication requirements of the local end. The R criterion can be used for rank determination in wireless communication, and the reselection process of the communication area can be performed to ensure that the local end can switch to a communication area with better communication quality. Based on the R criterion, the signal strengths of the candidate communication areas can be arranged and compared, and the candidate communication area with the largest signal strength can be selected. The reselection hysteresis (Qhysts) and offset (Qoffsets) can also be considered to ensure the stability and reliability of wireless communication are taken into account when performing communication area reselection.

[0060] Specifically, such as Figure 6As shown, according to the communication parameters of the candidate communication areas, select the communication areas that meet the communication requirements of the local end and the perception requirements for the target object. First, determine the range of the target communication distance corresponding to the communication requirements of the local end and the range of the target frequency points corresponding to the perception requirements of the target object, and select the candidate communication areas that meet the following conditions at the same time: the distance between the corresponding device in the candidate communication area and the local end is within the range of the target communication distance, and the frequency points supported by the wireless perception of the candidate communication area are within the range of the target frequency points. The communication parameters of the selected candidate areas can meet the communication requirements of the local end and the perception requirements of the target object at the same time. Then, determine the candidate area with the best communication quality and perception effect among the selected candidate areas as the target communication area. For example, when a user uses a terminal device locally and enables a certain gesture perception function, and the terminal device wants to perceive the gesture through wireless perception. In this case, if the current communication area does not support gesture perception, it is necessary to select a communication area that can perceive the gesture from the candidate communication areas. The current communication area cannot meet the perception requirements. The user obtains the communication parameters of the nearby communication areas through the terminal device and selects the communication areas whose communication parameters can meet the requirements of gesture perception and the communication requirements of the terminal device. Then, determine the communication area with the best communication quality and perception effect among the communication areas that meet the communication requirements and perception requirements.

[0061] S300, switch the communication area to the target communication area;

[0062] In this embodiment, after determining the target communication area in the candidate communication areas whose communication parameters meet the perception conditions and communication conditions, switch the communication area of the local end to the target communication area. In the target communication area, the local end can perform wireless perception on the target object while maintaining the wireless communication state between the local end and the target communication area. For example, when the target object has the requirement of gesture perception, obtain the distance between the corresponding device in the nearby communication area and the terminal device, and the frequency points supported by the wireless perception of the communication area, and after determining the target communication area that meets the communication conditions and perception conditions, switch the terminal device from the current communication area to the target communication area, and obtain the change of the CSI signal caused by the gesture perception of the target object through the terminal device, so as to perform gesture perception on the target object.

[0063] In a preferred embodiment of the present application, if no target communication area that meets both the communication conditions and the perception conditions is found in the candidate communication areas, give priority to the communication requirements of the local end, and only select the communication areas that meet the communication requirements of the local end in the candidate communication areas to keep the local end in a wireless communication state.

[0064] Through the above method, in a wireless communication environment with sensing requirements, in response to an instruction to switch the communication area, communication parameters of candidate communication areas are obtained, and a communication area that meets the sensing conditions and communication conditions is selected from the candidate communication areas, a target communication area whose communication parameters in the candidate communication areas meet the sensing conditions and communication conditions is determined, and the communication area is switched to the target communication area that simultaneously meets the communication requirements and sensing requirements. By obtaining the communication parameters of the communication area, this application determines the communication area with the best communication quality and sensing effect among the communication areas that meet the communication requirements and sensing requirements. This application can quickly determine the target communication area that can simultaneously meet the communication requirements and sensing requirements through the sensing parameters of the communication area, ensuring the wireless sensing quality and wireless communication quality, and improving the user experience.

[0065] In an embodiment of the present application, as Figure 2 shown, the method further includes:

[0066] S400, input the communication parameters and sensing parameters of the candidate communication area into the first intelligent engine to obtain a first prediction result; the sensing parameter is used to characterize the amplitude of the action to be sensed.

[0067] In this embodiment, in the case of needing to switch the communication area, the communication parameters of the candidate communication area and the sensing parameters of the current environment are obtained, and the communication parameters of the candidate communication area and the sensing parameters of the current environment are input into the first intelligent engine to obtain a first prediction result; the sensing parameter is used to characterize the amplitude of the action to be sensed, and the sensing parameters of the current environment can be the frequency points supported by the candidate communication area and the distance between the local end and the target object. Based on the first prediction result, it can be determined whether the communication parameters of the candidate communication area can be used to sense the action of the target amplitude. For example, the first intelligent engine can be configured with a first prediction algorithm, and the first prediction algorithm is used to predict whether the candidate communication area meets the sensing conditions. Based on the communication parameters of each candidate communication area and the sensing parameters of the current environment, through the first prediction algorithm, it can be judged whether each candidate area meets the sensing conditions. In the case where the sensing type of the target object is gesture sensing, the communication parameters of the candidate communication area and the sensing parameters of the current environment are input into the first intelligent engine, and then through the first prediction algorithm, it is determined whether the communication parameters of the candidate communication area can be used to sense the gesture action amplitude of the target object. The first prediction algorithm is obtained by training the second monitoring model based on the sensing parameters corresponding to different sensing types of the target object, and the second prediction algorithm is used to determine the sensing type of the target object; the sensing type of the target object includes at least one of the following: breathing sensing, gesture sensing, fall sensing, and intrusion sensing.

[0068] S500. If the first prediction result indicates that the communication parameters of the candidate communication area can be used to sense the action of the target amplitude, the communication parameters meet the sensing conditions.

[0069] In this embodiment, after inputting the communication parameters and sensing parameters of the candidate communication area into the first intelligent engine to obtain the first prediction result, based on the first prediction result, it is determined whether the communication parameters of each selected communication area can be used to sense the action of the target amplitude; if the first prediction result indicates that the communication parameters of the candidate communication area can be used to sense the action of the target amplitude, it indicates that the communication parameters of this communication area meet the sensing conditions. Based on the communication parameters that meet the sensing conditions, after wireless communication transmission can be performed between the local end and this communication area, through the CSI signal sent by the communication device corresponding to the communication area, after reflection or diffraction caused by the action of the target object, and then by obtaining the change of the CSI signal at the local end, the target object can be sensed. For example, in the case where the sensing type of the target object is gesture sensing, if the communication parameters of the candidate communication area can be used to sense the action of the gesture sensing amplitude of the target object, it is determined that the communication parameters of this communication area meet the gesture sensing conditions, perform wireless communication transmission between the terminal device and this communication area, the CSI signal sent by the base station corresponding to this communication area, after reflection or diffraction caused by the gesture action of the target object, and then obtain the change of the gesture action represented by the CSI signal through the terminal device to sense the gesture action of the target object.

[0070] In an embodiment of the present application, the communication parameters at least include the distance between the communication device corresponding to the candidate communication area and the local end.

[0071] In this embodiment, after obtaining the communication parameters of the candidate communication areas, the candidate areas whose communication parameters meet the communication requirements of the local end are determined. The communication parameters at least include the distance between the communication device corresponding to the candidate communication area and the local end. The communication device corresponding to the candidate communication area can be a base station or a router. In the case of needing to switch the communication area, the distances between the communication devices corresponding to the respective candidate communication areas and the local end can be compared with the maximum distance threshold between the communication device and the local end. The maximum distance threshold between the communication device and the local end represents the maximum distance for the local end to perform wireless communication transmission with the communication area. If the distance between the communication device and the local end exceeds the maximum distance threshold, the communication transmission quality between the local end and the communication area cannot be guaranteed. The candidate communication areas whose distances between the corresponding communication devices and the local end are not greater than the maximum distance threshold can be selected, and the candidate communication areas with a relatively short distance between the communication device and the local end can be further selected, and at the same time, whether these candidate communication areas meet the perception requirements of the target object is considered. For example, there is a gesture perception requirement of the target object between the terminal device and the current base station, and the current base station cannot meet the gesture perception condition, and it is necessary to switch the current base station to a base station that meets the gesture perception condition and the communication condition of the terminal device. The maximum distance threshold between the base station and the terminal device is determined, and the base stations whose distances from the terminal device are less than the maximum distance threshold are selected, and then the base stations that meet the gesture perception requirements of the target object are further determined from these base stations.

[0072] In an embodiment of the present application, the communication parameters include the set of frequency points supported by the candidate communication area;

[0073] The perception condition indicates that the set of frequency points contains the target frequency point; the target frequency point is a frequency point that can be used to sense the target object in the target amplitude action.

[0074] In this embodiment, the communication parameters of the candidate communication area further include the frequency point set supported by the candidate communication area. The different ranges of frequency point sets supported by each candidate communication area can meet different types of wireless sensing requirements. After determining the sensing type of the current target object, the target frequency point for sensing the target object's target amplitude action can be obtained. The target frequency point of the target object's target amplitude action can be the frequency point corresponding to the minimum amplitude action of the target object under the current sensing type. According to the target frequency point of the current target object, first determine whether the target frequency point is included in the frequency point set supported by the current communication area. If the target frequency point is included in the frequency point set supported by the current communication area, it indicates that the current communication area can meet the sensing requirements of the target object. If the target frequency point is not included in the frequency point set supported by the current communication area, it indicates that the current communication area cannot meet the sensing requirements of the target object, and it is necessary to determine the target communication area that can meet the sensing requirements of the target object from the candidate communication areas. Specifically, the frequency point sets supported by each candidate communication area can be obtained, the candidate communication areas corresponding to the frequency point sets containing the target frequency point can be selected, and the candidate communication areas that meet the communication requirements of the local end among these candidate communication areas can be determined as the target communication area. For example, if the current sensing type of the target object is respiration sensing, the target frequency point corresponding to the minimum amplitude respiration action of the target object can be determined, the frequency point sets supported by each base station can be obtained, the base stations corresponding to the frequency point sets containing the target frequency point can be selected, and the base stations that meet the communication requirements of the terminal device among the base stations that meet the respiration sensing can be determined as the target base station. The terminal device can perform wireless communication with the target base station and simultaneously perform respiration sensing on the target object.

[0075] In one embodiment of the present application, the method further includes:

[0076] Obtaining the target frequency point corresponding to the sensing type of the target object;

[0077] The target frequency point is determined by the amplitude required for sensing and / or the phase difference determined by the environment.

[0078] In this embodiment, after determining the perception type of the current target object, the target frequency point for perceiving the current target object's target amplitude action is obtained. The target frequency point of the target object's target amplitude action can be the frequency point corresponding to the action with the minimum amplitude of the target object under the current perception type, and the target frequency point is determined by the required perceived amplitude and / or the phase difference determined by the environment. Specifically, the target frequency point can be determined by the minimum action amplitude of the target object and / or the phase difference determined by the current perception environment. Specifically, after determining the perception type of the current target object, the minimum frequency point value corresponding to the perception type of the current target object can be calculated through a target function according to the minimum displacement distance value characterized by the minimum action amplitude of the target object under the current perception type and the minimum phase difference of the current perception environment.

[0079] For example, the target function is where C is a fixed value, which can be the electromagnetic wave propagation speed; Δφ is the minimum phase difference of the current environment; Δd is the minimum displacement distance value corresponding to the minimum action amplitude of the current target object, and the minimum displacement distance values corresponding to the minimum action amplitudes of the target object in different perception types are different; the minimum frequency point value f corresponding to the perception type of the current target object can be calculated according to the minimum phase difference Δφ of the current environment and the minimum displacement distance value corresponding to the minimum action amplitude of the target object.

[0080] After obtaining the minimum frequency point value corresponding to the perception type of the current target object, the target frequency point range corresponding to the action with the target amplitude of the target object under the current perception type can be obtained. According to the target frequency point range, it can be determined whether the wireless perception frequency points supported by the current communication area are within the target frequency point range, or whether the wireless perception frequency points supported by the candidate communication area are within the target frequency point range, so as to determine the target communication area that can meet the perception requirements of the target object.

[0081] In an embodiment of the present application, the method further includes:

[0082] Responding to the communication parameters of the current communication area not meeting the perception conditions or the communication conditions, generating an instruction to switch the communication area.

[0083] In this embodiment, in the case of having a sensing requirement in the current wireless communication environment, if the communication parameters of the current communication area do not meet the sensing conditions of the target object or the communication conditions of the local end, it is necessary to switch the current communication area to a communication area that meets both the sensing conditions and the communication conditions. If the communication parameters of the current communication area do not meet the sensing conditions of the target object, it indicates that the wireless sensing frequency band supported by the current communication area is not within the target frequency band range corresponding to the target amplitude action of the target object under the current sensing type. In the current communication area, wireless sensing of the target object cannot be achieved. In this case, in response to the communication parameters of the current communication area not meeting the sensing conditions of the target object, a command to switch the communication area is generated, and based on the command to switch the communication area, the current communication area is switched to a communication area that meets the sensing conditions of the target object, while ensuring the wireless communication quality of the local end. If the communication parameters of the current communication area do not meet the communication conditions of the local end, it indicates that the distance between the communication device corresponding to the current communication area and the local end is not within the range of the target communication distance. In the current communication area, wireless communication between the local end and the communication device cannot be achieved. In this case, in response to the communication parameters of the current communication area not meeting the communication conditions of the local end, a command to switch the communication area is generated, and based on the command to switch the communication area, the current communication area is switched to a communication area that meets the communication conditions of the local end, while ensuring the wireless sensing quality of the target object.

[0084] In one embodiment of the present application, as Figure 3 shown, the method further includes:

[0085] S600, obtain a transmission parameter set associated with the local end, where the transmission parameter set characterizes the signal transmission quality between the local end and the communication area;

[0086] In this embodiment, in the case of having a sensing requirement in the current wireless communication environment, when selecting a communication area that meets the sensing conditions from the candidate communication areas according to the communication parameters of the candidate communication areas, it is necessary to simultaneously consider whether the candidate area meets the communication conditions of the local end. Specifically, in the process of selecting a communication area that meets the communication conditions of the local end from the candidate communication areas, first obtain a transmission parameter set associated with the local end, where the transmission parameter set characterizes the signal transmission quality between the local end and the communication area; the transmission parameter set may include the frequency band range corresponding to the wireless communication transmission of the local end, and the distance between the local end and the communication device corresponding to the communication area.

[0087] S700, determine the transmission parameters in the transmission parameter set that are adapted to the communication requirements of the local end as the target transmission parameters.

[0088] In this embodiment, after obtaining the set of transmission parameters associated with the local end, the transmission parameters in the set of transmission parameters that are adapted to the communication requirements of the local end are determined as the target transmission parameters. In the communication area corresponding to the target transmission parameters, the local end can perform wireless communication transmission with the communication device. The communication area corresponding to the target transmission parameters can be selected from the candidate communication areas. The communication area corresponding to the target transmission parameters can meet the communication conditions of the local end, ensure the communication quality of the wireless communication transmission of the local end, and determine to select a communication area that meets the sensing requirements of the target object. For example, the frequency band range corresponding to the wireless communication transmission of the local end and the communication distance between the local end and the communication device corresponding to the communication area can be determined, and then a communication area that meets the frequency band range and the communication distance is selected from the candidate communication areas, so that the local end performs wireless communication transmission in this communication area, and at the same time, it is necessary to ensure that this communication area meets the sensing requirements of the target object.

[0089] In an embodiment of the present application, as Figure 4 shown, the method further includes:

[0090] S800, obtain the first transmission parameters corresponding to the candidate communication area that is adapted to the sensing requirements of the target object, and compare the first transmission parameters with the target transmission parameters;

[0091] In this embodiment, after determining the transmission parameters in the set of transmission parameters that are adapted to the communication requirements of the local end as the target transmission parameters, obtain the first transmission parameters corresponding to the candidate communication area that is adapted to the sensing requirements of the target object, and compare the first transmission parameters with the target transmission parameters. Specifically, the currently selected candidate communication area meets the sensing requirements of the target object, and it is necessary to compare the first transmission parameters corresponding to the current candidate communication area with the target transmission parameters to determine whether the current candidate communication area meets the communication requirements of the local end. In the case where the first transmission parameters are different from the target transmission parameters, it indicates that the current candidate communication area cannot meet the communication requirements of the local end, and it is necessary to select other communication areas from the candidate communication areas that meet the sensing requirements of the target object to ensure that the finally selected communication area meets both the sensing requirements of the target object and the communication requirements of the local end.

[0092] S900, in the case where the first transmission parameters are the same as the target transmission parameters, determine the candidate communication area corresponding to the first transmission parameters as the target communication area.

[0093] In this embodiment, after comparing the first transmission parameter corresponding to the current candidate communication area with the target transmission parameter, when the first transmission parameter is the same as the target transmission parameter, it indicates that the current candidate communication area meets the communication requirements of the local end. The candidate communication area corresponding to the first transmission parameter can be determined as the target communication area. The target communication area can simultaneously meet the sensing requirements of the target object and the communication requirements of the local end, and can ensure the sensing quality and communication quality. For example, when the target object has a requirement for gesture sensing, first determine a candidate communication area adapted to the gesture sensing requirement of the target object, and obtain the first transmission parameter corresponding to the candidate communication area adapted to the gesture sensing requirement of the target object. Compare the first transmission parameter with the target transmission parameter adapted to the communication requirement of the terminal device. When the first transmission parameter is the same as the target transmission parameter, it indicates that the current candidate communication area can also meet the communication requirement of the terminal on the premise of meeting the gesture sensing requirement of the target object. Determine the candidate communication area as the target communication area, enable the terminal device to perform wireless communication transmission in the target communication area, and obtain the change in the CSI signal caused by the gesture sensing of the target object, so as to perform gesture sensing on the target object.

[0094] In a specific implementation manner of the present application, the user enables the wireless sensing function through the terminal. The terminal can obtain the minimum phase difference Δφ of the current environment, and then determine whether the currently used terminal supports the wireless sensing function. If it does not support, the sensing operation ends; if it supports, determine the type of wireless sensing through the terminal. For example, the terminal determines that the current sensing type is gesture sensing, and then calculates the minimum frequency point value f corresponding to the gesture sensing type of the current target object according to the minimum phase difference Δφ of the current environment and the minimum displacement distance value Δd corresponding to the minimum action amplitude of the current target object. Input the frequency points supported by the candidate communication area and the distance between the terminal and the target object into the first intelligent engine to obtain the prediction result of the candidate communication area, determine whether the frequency points supported by the communication area include the minimum frequency point value, and further determine the communication area supporting gesture sensing. And in the communication area supporting gesture sensing, based on the S, R criterion, further select the communication area supporting the communication function of the terminal. After determining the communication area supporting wireless sensing and communication functions, collect the current CSI signal used for sensing through the terminal to perform gesture sensing on the environment.
