[0056] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the disclosure will be more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0057] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0058] It should be understood that the various steps described in the method embodiments of the present disclosure may be performed in different orders and / or in parallel. In addition, the method embodiments may include additional steps and / or omit the steps shown. The scope of the present disclosure is not limited in this respect.

[0059] It should be noted that the concepts such as "first" and "second" mentioned in the present disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0060] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0061] In order to illustrate the smart reflective surface, an embodiment of the present disclosure provides an application scenario of the smart reflective surface.

[0062] Figure 1 A diagram showing an application scenario of a smart reflective surface in the related art is shown. Figure 1 As shown:

[0063] In a normal scenario, the terminal 10 and the base station 20 are usually transmitted through a wireless network. Since wireless signals in a wireless network are usually transmitted in a straight line of sight, the terminal 10 and the base station 20 are usually also transmitted in a straight line of sight.

[0064] During the wireless transmission between the terminal 10 and the base station 20, there may be a large obstacle on the straight transmission path, which blocks the passage of the wireless signal. In this case, the terminal 10 can send the wireless signal to the smart reflective surface 30, and the smart reflective surface 30 reflects the wireless signal to the base station 20. In this way, the purpose of avoiding obstacles and transmitting wireless signals is achieved.

[0065] In the above application scenario, since the smart reflective surface 30 needs to be used for signal reflection, the position information of the smart reflective surface 30 becomes extremely important.

[0066] However, there is currently a lack of a method for positioning the intelligent reflective surface 30 .

[0067] In order to solve the above problems, the present disclosure provides a positioning method, system, device, equipment and storage medium for a smart reflective surface.

[0068] Below, the positioning system of the intelligent reflective surface provided by the present disclosure is first described.

[0069] Figure 2 FIG. 2 shows an architecture diagram of a positioning system of a smart reflective surface provided by the present disclosure. Figure 2 As shown, the positioning system 20 of the smart reflective surface in the embodiment of the present disclosure may include:

[0070] Base station 202 and terminal 204;

[0071] The base station 202 is used to determine the direction angle of the positioning signal received by the base station 202 and the signal strength of the positioning signal according to the positioning signal, and determine the position information of the intelligent reflective surface according to the direction angle of the positioning signal received by the base station 202 and the signal strength of the positioning signal. There are multiple terminals 204, and the transmission powers of the multiple terminals 204 are the same;

[0072] The terminal is used to send a positioning signal including the location information of the terminal 204 to the base station 202 .

[0073] It should be noted that the positioning signal may be a wireless signal.

[0074] Optionally, the wireless signal uses standard communication technology and / or protocol. The network corresponding to the wireless signal is usually the Internet, but it can also be any network, including but not limited to a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a mobile, wired or wireless network, a private network or any combination of a virtual private network).

[0075] In some embodiments, technologies and / or formats including Hyper Text Mark-up Language (HTML), Extensible Markup Language (XML), etc. are used to represent data exchanged through the network. In addition, conventional encryption technologies such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), Internet Protocol Security (IPsec), etc. can also be used to encrypt all or some links. In other embodiments, customized and / or dedicated data communication technologies can also be used to replace or supplement the above data communication technologies.

[0076] The terminal 204 may be any electronic device, including but not limited to a smart phone, a tablet computer, a laptop computer, a desktop computer, a wearable device, an augmented reality device, a virtual reality device, etc.

[0077] Optionally, the clients of the application programs installed in different terminals 204 are the same, or are clients of the same type of application programs based on different operating systems.

[0078] Based on the different platforms of the terminal 204, the specific form of the client of the application program may also be different, for example, the client of the application program may be a mobile client, a PC client, etc. This application does not make any limitation here.

[0079] Those skilled in the art will know that Figure 2The number of terminals 204, base stations 202 and smart reflective surfaces in the figure is only for illustration, and any number of terminals 204, base stations 202 and smart reflective surfaces may be provided according to actual needs. The embodiments of the present disclosure are not limited to this.

[0080] Based on the same inventive concept, an embodiment of the present disclosure discloses a method for positioning a smart reflective surface. Figure 3 A flow chart of a positioning method for a smart reflective surface in an embodiment of the present disclosure is shown. Figure 3 As shown, the positioning method of the smart reflective surface in the embodiment of the present disclosure may include:

[0081] S302, obtaining positioning signals respectively sent by at least two target terminals, wherein the target terminal is a terminal that reflects the signal to the base station via the intelligent reflection surface, the transmission power of the multiple target terminals is the same, and the positioning signal contains the location information of the target terminal.

[0082] It should be noted that the location information of the terminal may include information that can represent the geographical location of the terminal. Exemplarily, the location information of the terminal may include the latitude and longitude information of the terminal.

[0083] As a specific example, S302 may include:

[0084] After determining its own geographical location information, the terminal generates a positioning signal based on its own geographical location information, and then transmits the positioning signal to the base station through reflection by the intelligent reflective surface.

[0085] S304: Determine the direction angle at which the base station receives the positioning signal and the signal strength of the positioning signal according to the positioning signal.

[0086] It should be noted that the direction angle of the positioning signal may be the angle at which the positioning signal is incident when the base station receives the positioning signal.

[0087] It should be noted that the base station may be a base station configured with an array antenna.

[0088] The method for the base station to determine the direction angle of the positioning signal may include:

[0089] There are multiple array antennas configured on the base station, and the direction angle of the positioning signal can be determined by the differences in the positioning signals received by the array antennas at different angles.

[0090] For example, since the distances from the positioning signal to the array antennas in different directions are different, the positioning signals received by different array antennas are different. The direction angle of the positioning signal can be determined by the difference in the positioning signals received by different array antennas.

[0091] A more detailed method for determining the direction angle of the positioning signal is not repeated in the embodiments of the present disclosure.

[0092] It is understandable that the method for determining the strength of the positioning signal is a method well known to those skilled in the art and will not be described in detail here.

[0093] S306: Determine the position information of the smart reflective surface according to the direction angle of the positioning signal received by the base station and the signal strength of the positioning signal.

[0094] It should be noted that there are many methods for determining the smart reflective surface according to the positioning signal and the signal strength of the positioning signal, which are not specifically limited here.

[0095] The method for positioning a smart reflective surface provided in an embodiment of the present disclosure includes: obtaining a positioning signal sent by a terminal, then determining the direction angle of the positioning signal and the signal strength of the positioning signal according to the positioning signal, and then determining the position of the smart reflective surface according to the direction angle and signal strength of the positioning signal. Thus, the positioning of the smart reflective surface is completed by obtaining the direction angle and signal strength of the positioning signal. The present disclosure improves the practicality of the smart reflective surface.

[0096] In some embodiments, the method for positioning the smart reflective surface may further include:

[0097] Receiving positioning signals sent by multiple terminals;

[0098] According to the location information of the base station, the location information of the terminal and the direction angle at which the base station receives the positioning signal sent by each terminal, one or more target terminals whose signals are reflected by the intelligent reflection surface to the base station are determined.

[0099] It should be noted that the location information of the base station may include the geographical location information of the base station.

[0100] As an example, when there is an intelligent reflecting surface within the coverage area of ​​the base station, after receiving the positioning signal of the terminal, the base station can draw a straight line based on the location information of the base station and the terminal. If the direction angle of the positioning signal coincides with the above straight line, it can be determined that the positioning signal is sent directly from the terminal to the base station. If the direction angle of the positioning signal does not coincide with the above straight line, it can be determined that the positioning signal is reflected by the intelligent reflecting surface and reaches the base station.

[0101] It should be noted that in the above example, the positions of the base station and the terminal can be determined based on the digitized map, and the above method can be used to determine whether the positioning signal is reflected by the smart reflective surface to reach the base station.

[0102] In some embodiments, S306 may include:

[0103] When the positioning signal is reflected from the terminal to the base station through the smart reflection surface, the position of the smart reflection surface that reflects the positioning signal from the terminal to the base station is determined according to the direction angle of the positioning signal and the signal strength of the positioning signal.

[0104] In the embodiment of the present disclosure, since it is first determined that the positioning signal used to measure the smart reflective surface is obtained by reflection from the smart reflective surface, it is possible to avoid the problem that it is difficult to obtain a positioning result after positioning the smart reflective surface using the above method without the positioning signal being reflected by the smart reflective surface, thereby causing a waste of resources. The embodiment of the present disclosure improves the efficiency of positioning the smart reflective surface.

[0105] In some embodiments, S306 may include:

[0106] The distances from the multiple terminals to the base station via the preset positions of the intelligent reflective surface are determined according to the location information of the multiple terminals.

[0107] It should be noted that the preset position of the intelligent reflective surface can be within the plane where the terminal and the base station are located, and can reach any position in the direction angle.

[0108] As an example, the method for determining the distance between the terminal and the preset position of the smart reflective surface may include:

[0109] The distance between the terminal and the preset position of the smart reflective surface is determined according to the first relationship.

[0110] Among them, the first relationship can be:

[0111]

[0112] Among them, D(p 1 , p 2 ) is the distance between the terminal and the preset position of the intelligent reflective surface, p 1 is the terminal position, p 2 Preset position for smart reflective surface, x p1 ,y p1 are the coordinates of the terminal, x p2 ,y p2 and H p2 are the coordinates of the preset positions of the intelligent reflective surface. p2 is the height of the smart reflective surface relative to the terminal.

[0113] Figure 4 A schematic diagram of a method for determining the location of a terminal and a base station is shown. Figure 4 As shown, p 1 is the terminal position, p 2 Preset position for smart reflective surface, p 3 is the base station location.

[0114] Similarly, the method for determining the distance between the base station and the preset position of the intelligent reflecting surface is the same as the above-mentioned method for determining the distance between the terminal and the intelligent reflecting surface, which will not be repeated here.

[0115] After determining the distance between base stations and the distance between the terminal and the smart reflective surface, the two distances may be added together to obtain the distance between the terminal and the base station.

[0116] The path loss values ​​between the multiple terminals and the base station are determined according to the distances between the multiple terminals and the preset positions of the intelligent reflecting surface respectively.

[0117] It should be noted that the path loss value between the terminal and the base station can be determined according to the distance between the terminal and the preset position of the smart reflective surface.

[0118] As an example, the method for determining the path loss value between the terminal and the base station may include:

[0119] The distance between the terminal and the base station is determined according to the second relationship.

[0120] The second relation can be:

[0121] PL(p 1 , p 3 )=32.4+20 log d(p 1 , p 3 )+20 log f

[0122] Among them, PL(p 1 , p 3 ) is the path loss between the terminal and the base station, d(p 1 , p 3 ) is the distance between the terminal and the base station, and f is the frequency of the positioning signal.

[0123] Determine whether the preset path loss value meets the preset condition, wherein the preset condition is determined according to the difference between the transmission power of the positioning signal sent by the target terminal and the signal strength of the positioning signal received by the base station.

[0124] It should be noted that the preset condition may include that a difference value obtained by subtracting a preset path loss value from the above difference value is within a preset range.

[0125] It should be noted that since the preset position of the intelligent reflecting surface is not necessarily the actual position of the intelligent reflecting surface, the path loss value between the terminal and the base station obtained based on the preset position of the intelligent reflecting surface may not necessarily satisfy the difference between the strength value of the positioning signal received by the base station and the terminal transmission power.

[0126] When the path loss value between each terminal and the base station matches the transmission power corresponding to the terminal and the signal strength value of the positioning signal corresponding to the terminal, the preset position of the smart reflecting surface is determined as the final position of the smart reflecting surface.

[0127] It should be noted that when the path loss value between the terminal and the base station obtained based on the preset position of the intelligent reflecting surface satisfies the difference between the strength value of the positioning signal received by the base station and the terminal transmission power, the preset position of the intelligent reflecting surface can be determined as the position of the intelligent reflecting surface.

[0128] It should be noted that the path loss value between the terminal and the base station obtained based on the preset position of the intelligent reflective surface satisfies the difference between the strength value of the positioning signal received by the base station and the terminal transmit power and may include:

[0129] The difference between the path loss value between the terminal and the base station obtained based on the preset position of the intelligent reflective surface and the difference between the strength value of the positioning signal received by the base station and the terminal transmission power meets the preset range. The preset range can be determined by the user and will not be repeated here.

[0130] Based on the same inventive concept, the embodiment of the present disclosure provides another intelligent terminal positioning method, which is applied to the terminal. In principle, the method can be executed by any electronic device with computer processing capabilities.

[0131] Figure 5 FIG. 4 is a flow chart showing another method for positioning a smart reflective surface in an embodiment of the present disclosure. Figure 5 As shown, the positioning method of the smart reflective surface may include:

[0132] S502, sending a positioning signal to a base station, so that the base station determines the direction angle at which the base station receives the positioning signal and the signal strength of the positioning signal according to the positioning signal, and determines the position information of the intelligent reflective surface according to the direction angle at which the base station receives the positioning signal and the signal strength of the positioning signal, there are multiple terminals, the transmission powers of the multiple terminals are the same, and the positioning signal includes the position information of the terminals;

[0133] S504: Receive location information of the smart reflective surface sent by the base station.

[0134] Since the principle of solving the problem in this method embodiment is similar to that in the above method embodiment, the implementation of this method embodiment can refer to the implementation of the above method embodiment, and the repeated parts will not be repeated.

[0135] The method for positioning a smart reflective surface provided in an embodiment of the present disclosure includes: obtaining a positioning signal sent by a terminal, then determining the direction angle of the positioning signal and the signal strength of the positioning signal according to the positioning signal, and then determining the position of the smart reflective surface according to the direction angle and signal strength of the positioning signal. Thus, the positioning of the smart reflective surface is completed by obtaining the direction angle and signal strength of the positioning signal. The present disclosure improves the practicality of the smart reflective surface.

[0136] Based on the same inventive concept, the present disclosure also provides a positioning device 600 for an intelligent reflective surface, and the device is applied to a base station, such as the following embodiment. Since the principle of solving the problem in the device embodiment is similar to that in the above method embodiment, the implementation of the device embodiment can refer to the implementation of the above method embodiment, and the repeated parts will not be repeated.

[0140] The second determination module 606 is used to determine the position information of the smart reflective surface according to the direction angle of the positioning signal received by the base station and the signal strength of the positioning signal.

[0141] In the positioning device of the intelligent reflective surface provided in the embodiment of the present disclosure, the acquisition module acquires the positioning signal sent by the terminal, and then the first receiving module determines the direction angle of the positioning signal and the signal strength of the positioning signal according to the positioning signal, and then the first determination module determines the position of the intelligent reflective surface according to the direction angle and signal strength of the acquired positioning signal. Thus, the positioning of the intelligent reflective surface is completed by acquiring the direction angle and signal strength of the positioning signal. The present disclosure improves the practicality of the intelligent reflective surface.

[0145] In the embodiment of the present disclosure, since it is first determined that the positioning signal used to measure the smart reflective surface is obtained by reflection from the smart reflective surface, it is possible to avoid the problem that it is difficult to obtain a positioning result after positioning the smart reflective surface using the above method without the positioning signal being reflected by the smart reflective surface, thereby causing a waste of resources. The embodiment of the present disclosure improves the efficiency of positioning the smart reflective surface.
