Correctly distinguishing between far and near fields is of great significance for designing more suitable RIS and repeater codebooks and improving the coverage capability of RIS and repeater. Currently, traditional far-field and near-field measurements are usually based on distance or time delay measurements, which have stringent requirements for time delay, amplitude and phase of RF devices, etc., and the device cost is relatively high, making the measurement inconvenient.

[0009] Fourthly, embodiments of this application also provide a position measurement method applied to a receiving device. The position measurement method includes: receiving a target reference signal transmitted by a signal conditioning device using a target codebook, wherein the target codebook is used by the signal conditioning device to adjust the beam of the received signal to a beam corresponding to the target codebook; obtaining a target measurement signal based on the signal characteristics of the target reference signal; and transmitting the target measurement signal to a transmitting device, such that the transmitting device determines the position of the receiving device relative to the signal conditioning device based on the target measurement signal.
[0010] Fifthly, embodiments of this application also provide a signal conditioning device, including: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the position measurement method as described in the first aspect.
[0011] In a sixth aspect, embodiments of this application also provide a base station, including: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the location measurement method as described in the second and third aspects.
[0012] In a seventh aspect, embodiments of this application also provide a terminal, including: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the position measurement method as described in the fourth aspect.

[0032] To make the objectives, technical methods, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0033] It should be noted that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than that shown in the flowchart. The terms "first," "second," etc., in the specification, claims, and the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0034] This application provides a position measurement method, a signal conditioning device, a base station, a terminal, a storage medium, and a computer program product. One embodiment of the position measurement method, applied to a signal conditioning device, includes: receiving a target reference signal and transmitting the target reference signal to a receiving device using a target codebook, wherein the target codebook is used to adjust the beam of the signal received by the signal conditioning device to a beam corresponding to the target codebook, and the signal characteristics of the target reference signal are used to determine the position of the receiving device relative to the signal conditioning device. Another embodiment of the position measurement method, applied to a receiving device, includes: receiving a target reference signal, wherein the target reference signal is received by the signal conditioning device from a transmitting device and transmitted to the receiving device using a target codebook, the target codebook being used by the signal conditioning device to adjust the beam of the received signal to a beam corresponding to the target codebook; and determining the position of the transmitting device relative to the signal conditioning device based on the signal characteristics of the detected target reference signal. Another embodiment of the position measurement method, applied to a transmitting device, includes: sending a target reference signal to a signal conditioning device, causing the signal conditioning device to transmit the target reference signal to a receiving device using a target codebook, wherein the target codebook is used by the signal conditioning device to adjust the beam of the received signal to a beam corresponding to the target codebook; receiving a target measurement signal sent by the receiving device, wherein the target measurement signal is obtained by the receiving device based on the signal characteristics of the target reference signal; and determining the position of the receiving device relative to the signal conditioning device based on the target measurement signal. Another embodiment of the position measurement method, applied to a receiving device, includes: receiving a target reference signal sent by the signal conditioning device using a target codebook, wherein the target codebook is used by the signal conditioning device to adjust the beam of the received signal to a beam corresponding to the target codebook; obtaining a target measurement signal based on the signal characteristics of the detected target reference signal; and sending the target measurement signal to a transmitting device, causing the transmitting device to determine the position of the receiving device relative to the signal conditioning device based on the target measurement signal. In the above embodiments, the signal conditioning device receives a target reference signal from the transmitting device and then sends the target reference signal to the receiving device using a target codebook. This allows the receiving device to determine the position of the transmitting device relative to the signal conditioning device based on the signal characteristics of the target reference signal. In other words, the target reference signal can be accurately sent to the receiving device in the form of a beam corresponding to the target codebook, facilitating subsequent position measurement by the receiving device. Unlike related technologies, the receiving device can perform position measurement based on the signal characteristics of the detected target reference signal. Therefore, it can avoid position measurement based on distance or time delay, thereby reducing the stringent requirements for time delay and amplitude and phase of radio frequency devices, achieving the goal of optimizing the measurement method and saving measurement costs.Therefore, the embodiments of this application can easily and effectively measure the position of a target while saving measurement costs, and then determine its far-field and near-field characteristics relative to the signal conditioning device based on the measured target position signal, so as to make more accurate overall communication design, thereby filling the technical gap of related measurement methods.
[0035] The embodiments of this application will be further described below with reference to the accompanying drawings.
[0036] like Figure 1 As shown, Figure 1 This is a schematic diagram of the implementation environment for a position measurement method provided in one embodiment of this application.
[0037] exist Figure 1 In the example, the implementation environment includes a base station 110, a signal conditioning device 120, and a terminal 130. Both the signal conditioning device 120 and the terminal 130 can receive wireless signals sent by the base station 110 and can also send wireless signals to the base station 110. At the same time, the signal conditioning device 120 and the terminal 130 can also send and receive wireless signals to each other.
[0038] It should be noted that the signal conditioning device 120 and the terminal 130 can move along the radiation sphere formed by the base station 110 when radiating signals to the outside, so as to receive the wireless signals sent by the base station 110 at different spatial locations. In a specific scenario, the positions of the signal conditioning device 120 and the terminal 130 relative to the base station 110 can be set according to the actual application conditions. For example, in a specific scenario, when the positions of the signal conditioning device 120 and the terminal 130 are determined relative to the base station 110, the position measurement method of this embodiment can be executed in that scenario, that is, the position of the terminal 130 relative to the signal conditioning device 120 can be measured.
[0039] In another feasible implementation, the signal conditioning device 120 can be a RIS. Compared with massive MIMO in conventional technology, RIS can bring a signal-to-noise ratio gain that is proportional to the square of the number of surface units, corresponding to higher system capacity. Therefore, it has a higher signal-to-noise ratio gain than that achievable by massive MIMO. As a passive device, RIS can adjust its own electromagnetic units to transmit the received wireless signal using a relevant beam. For example, when receiving a wireless signal from base station 110, RIS adjusts its own electromagnetic units to transmit the wireless signal outward by transmitting a beam.
[0040] In another feasible implementation, the signal conditioning device 120 can be a repeater. Compared to network nodes in conventional technology, the repeater is equipped with an antenna, which can extend the communication distance, increase the maximum number of nodes, and use different communication rates in different network segments, thereby improving network reliability. The repeater can generate a coherent beam to transmit the received wireless signal. For example, when it receives a wireless signal from base station 110, the repeater generates a transmit beam to transmit the wireless signal outward.
[0041] In one feasible implementation, such as Figure 1 As shown, terminal 130 may include a first signal receiving module 131 and a first signal transmitting module 132, which are connected via wired or wireless means. The first signal receiving module 131 can receive wireless signals transmitted by base station 110 or signal conditioning device 110 within the range of the radiation sphere, and transmit the received wireless signals to the first signal transmitting module 132 for outputting corresponding wireless signals. In some examples, the first signal receiving module 131 may be a receiving antenna module, and the first signal transmitting module 132 may be a transmitting antenna module, with the receiving antenna module and transmitting antenna module connected via wired means such as a signal line. In other examples, the first signal receiving module 131 may be a device including a receiving antenna module and a wireless communication module, with the receiving antenna module electrically connected to the wireless communication module, and the first signal transmitting module 132 may be a transmitting antenna module, with the wireless communication module and transmitting antenna module connected via wireless means such as Bluetooth or Wi-Fi.
[0042] In another feasible implementation, terminal 130 may be referred to as an access terminal, user equipment (UE), user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, wireless communication device, user agent, or user device. For example, terminal 130 may be a cellular phone, cordless phone, Session Initiation Protocol (SIP) phone, Wireless Local Loop (WLL) station, Personal Digital Assistant (PDA), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, terminal device in a 5G network or a future 5G or higher network, etc. This embodiment does not specifically limit it in this way.
[0043] Base station 110 has at least the function of transmitting wireless signals based on preset operating logic or based on operator control. Base station 110 can be a general mobile communication base station or a millimeter-wave AAS base station; no specific limitation is made here.
[0044] The signal conditioning device 120 has at least the function of receiving a target reference signal and transmitting the target reference signal to a receiving device using a target codebook. The target codebook is used to adjust the beam of the signal received by the signal conditioning device 120 to the beam corresponding to the target codebook. The signal characteristics of the target reference signal are used to determine the position of the receiving device relative to the signal conditioning device 130.
[0045] In one feasible implementation, when the receiving device is a base station 110, the signal conditioning device 120 has at least the function of receiving a target reference signal from the base station 110 and sending the target reference signal to the base station 110 using a target codebook. For example, it can receive a target reference signal from the terminal 130 and send the target reference signal to the base station 110 using a target codebook in response to an operator's operation on the signal conditioning device 120, or receive a target reference signal from the base station 110 and send the target reference signal to the terminal 130 using a target codebook.
[0046] In another feasible implementation, when the receiving device is terminal 130, the signal conditioning device 120 is at least capable of receiving a target reference signal and transmitting the target reference signal to terminal 130 using a target codebook, such that terminal 130 obtains a target measurement signal based on the signal characteristics of the target reference signal, and transmits the target measurement signal to base station 110 to determine the position of terminal 130 relative to signal conditioning device 120. For example, it is capable of receiving the target reference signal and transmitting the target reference signal to terminal 130 using a target codebook in response to an operator's operation on signal conditioning device 120.
[0047] Terminal 130 has at least the functions of receiving a target reference signal sent by signal conditioning device 120 using a target codebook, obtaining a target measurement signal based on the signal characteristics of the detected target reference signal, and sending the target measurement signal to base station 110. For example, it can respond to the operator's operation on terminal 130, receive reference signal indication information sent by base station 110, and when it is determined that a target reference signal has been received based on the reference signal indication information, terminal 130 obtains the target measurement signal based on the target reference signal and sends the target measurement signal to base station 110.
[0048] It should be noted that the functions of the base station 110, the signal conditioning device 120 and the terminal 130 can be applied to different application scenarios, and there is no limitation here.
[0049] Those skilled in the art will understand that this implementation environment can be applied to 5G, 6G communication network systems and subsequent evolved mobile communication network systems, and this embodiment does not specifically limit it.
[0050] It will be understood by those skilled in the art that Figure 1 The implementation environment shown does not constitute a limitation on the embodiments of this application, and may include more or fewer components than shown, or combine certain components, or have different component arrangements.
[0051] Based on the above implementation environment, various embodiments of the position measurement method of this application are presented below.
[0052] like Figure 2 As shown, Figure 2 This is a flowchart of a position measurement method provided in one embodiment of this application. This position measurement method is applied to a signal conditioning device, such as... Figure 1 The signal conditioning device 120 in the illustrated embodiment. This position measurement method may include, but is not limited to, steps S110 to S120.
[0053] Step S110: Receive the target reference signal from the transmitting device;
[0054] Step S120: The target reference signal is sent to the receiving device using the target codebook, so that the receiving device determines the position of the transmitting device relative to the signal conditioning device based on the signal characteristics of the detected target reference signal.
[0055] It should be noted that the target codebook is used to adjust the beam of the signal received by the signal conditioning device to the beam corresponding to the target codebook. In other words, when a target reference signal is received from the transmitting device, the target beam of the target codebook can be obtained by adjusting the target codebook, and then the target reference signal can be sent to the receiving device using the target beam corresponding to the target codebook.
[0056] It should be noted that the signal characteristics of the target reference signal include the main lobe phase of the target reference signal detected by the receiving device.
[0057] It should be noted that the transmitting device in this embodiment may be, but is not limited to, [the following]. Figure 1 The terminal 130 in the illustrated embodiment, and the receiving device in this embodiment, may be, but is not limited to, a terminal 130. Figure 1In the illustrated embodiment, the target reference signal for the base station 110 is, correspondingly, the uplink target reference signal; or, those skilled in the art can choose to set up the corresponding transmitting or receiving device according to the actual application scenario, and this embodiment does not impose any restrictions. In order to more conveniently describe the application scenario and principle of this application, the following related embodiments are described with the terminal as the transmitting device and the base station as the receiving device, but they should not be construed as limitations on the embodiments of this application.
[0058] In this step, since the target reference signal is received from the terminal in step S110, the target reference signal can be sent to the base station using a target codebook in step S120. This allows the base station to determine the terminal's position relative to the signal conditioning device based on the signal characteristics of the target reference signal. In other words, the target reference signal can be accurately sent to the base station in the form of a beam corresponding to the target codebook, facilitating subsequent position measurement by the base station. Unlike related technologies, the base station can perform position measurement based on the signal characteristics of the detected target reference signal, thus avoiding position measurement based on distance or time delay. This reduces the stringent requirements for time delay and the amplitude of radio frequency devices, achieving the goal of optimizing the measurement method and saving measurement costs. Therefore, the embodiments of this application can easily and effectively achieve target position measurement while saving measurement costs. Furthermore, based on the measured target position signal, its far-field and near-field characteristics relative to the signal conditioning device can be determined, facilitating more accurate overall communication design and filling the technical gaps in related measurement methods.
[0059] It should be noted that the signal conditioning device in this embodiment is configured with multiple first codebooks, and the target codebook is one of the multiple first codebooks. The signal conditioning device can select one of the multiple first codebooks as the target codebook to send the target reference signal to the base station. The specific selection method and principle will be explained in the following embodiments, and will not be detailed here.
[0060] One embodiment of this application may include, but is not limited to, step S130.
[0061] Step S130: Receive codebook indication information.
[0062] In one feasible implementation, the codebook indication information includes at least one of the following:
[0063] A codebook number;
[0064] The beam spacing between adjacent target beams, where the target beams are multiple beams corresponding to multiple first codebooks;
[0065] The number of target beams;
[0066] Measurement of azimuth indication information.
[0067] In this step, by receiving the codebook indication information, it is convenient to select one from multiple first codebooks as the target codebook based on the codebook indication information in subsequent steps.
[0068] It should be noted that the multiple first codebooks may also but are not limited to including a pair of identical first codebooks for Doppler compensation, which are used to indicate whether to perform Doppler compensation. For example, a 1-bit signaling can be used to indicate that in the codebook corresponding to the target beam indicated by the codebook indication information to the signal conditioning device, there is a repeated codebook, which is used to assist in Doppler compensation. When this information is enabled, the minimum number of target beams required needs to be increased by 1; in another feasible implementation, it can be defaulted that the last codebook is the same as the codebook with the strongest target beam or default that the last codebook is the codebook in the middle of the target beam. Then, this information can be omitted, and it is defaulted that Doppler compensation is not required.
[0069] It should be noted that a codebook number B id As the number of the reference codebook, the remaining codebook numbers can be correspondingly determined in combination with other information in the codebook indication information, so as to obtain all the codebook numbers. The corresponding beams can be the starting target beam or the central target beam of the indicated multiple target beams, etc.; by numbering the multiple first codebooks, the target beams corresponding to each first codebook can be distinguished. Since the target beam corresponding to each first codebook can be used to send a corresponding target reference signal, it is convenient to send target reference signals through the target beams corresponding to each first codebook respectively for position measurement in subsequent steps.
[0070] It should be noted that since the azimuth dimensions of different target beams may be different, such as the azimuth dimension, the elevation dimension, and the two-dimensional including the azimuth dimension and the elevation dimension, etc., the number of target beams can also change accordingly with the change of the azimuth dimension, and corresponding indications need to be made in specific application scenarios.
[0071] For example, referring to Figure 3 , when indicating the multiple first codebooks of the azimuth dimension, the multiple first codebooks are arranged in a similar "one" - shaped distribution in space, that is, Figure 3 the part of the cross - hatched line shown in the middle of
[0072] As Figure 4As shown, when multiple first codebooks indicating the pitch dimension are arranged in a spatial pattern resembling the letter "I", then... Figure 4 The section shown in the middle of the image has multiple first codebooks with the same weight in the azimuth dimension and different weights in the elevation dimension. Multiple first codebooks can be set to have the same spatial frequency interval in the elevation dimension. When Doppler compensation is not indicated, the minimum number of codebooks is 3. When Doppler compensation is indicated, the minimum number of codebooks is 4, with one codebook appearing twice (which can be assumed to be the middle codebook).
[0073] like Figure 5 As shown, when multiple first codebooks in two dimensions, indicating azimuth and elevation, are arranged in a cross shape in space, this is... Figure 5 The section shown in the middle of the diagram is divided into two parts: one part has the same weight in the azimuth dimension, and the other part has the same weight in the elevation dimension. Two spatially adjacent codebooks can be set with the same spatial frequency interval in either the azimuth or elevation dimension. When Doppler compensation is not indicated, the minimum number of codebooks is 5. When Doppler compensation is indicated, the minimum number of codebooks is 6, with one codebook appearing twice (which can be assumed to be the middle codebook).
[0074] It should be noted that the azimuth dimension, elevation dimension, and two-dimensional array including azimuth and elevation dimensions in the above embodiments are merely principle examples for describing the azimuth dimension of the target beam, and are not intended to be the only limitation. In specific application scenarios, other azimuth dimensions of the target beam can be defined or found for indication. For example, spatial angle adjustment processing can be performed on the azimuth dimension to obtain another dimension relative to the azimuth dimension, or spatial angle adjustment processing can be performed on the elevation dimension to obtain another dimension relative to the elevation dimension, or spatial angle adjustment processing can be performed on the two-dimensional array of azimuth and elevation dimensions to obtain another dimension relative to the two-dimensional array of azimuth and elevation dimensions, etc.
[0075] It should be noted that the measurement azimuth indication information is used to indicate the specific azimuth of the target beam measurement in subsequent steps. For example, it can be measurement azimuth indication information indicating only the azimuth dimension measurement, or measurement azimuth indication information indicating only the elevation dimension measurement, or measurement azimuth indication information indicating two-dimensional measurement simultaneously in both azimuth and elevation dimensions, etc. The number of target beams indicating the corresponding dimension can be selected according to the specific dimension indicated. That is, the number of target beams can be the number of target beams in the azimuth dimension alone, the number of target beams in the elevation dimension alone, or the sum of the number of target beams corresponding to the azimuth and elevation dimensions respectively. If only one dimension of the target beam is indicated, the number of target beams can be the number of target beams in the azimuth dimension, the number of target beams in the elevation dimension, or the number of beams common to both the azimuth and elevation dimensions; for example, referring to... Figures 3-5 The minimum number of target beams in a single dimension is 3, and the minimum number of target beams in two dimensions is 5 (i.e., at least 3 beams in the azimuth dimension and at least 3 beams in the elevation dimension, with both sharing 1 beam). If it is a two-dimensional indication, then the codebook number B in the above parameters is used. id It can be set to the codebook number corresponding to the target beam that intersects the azimuth and elevation dimensions. This information can also be omitted. In this case, the number of one-dimensional beams can be 3, 4, etc., and the number of two-dimensional beams can be 5, 6, etc. For example, this information can be indicated by 1-bit or 2-bit signaling. When omitted, azimuth or two-dimensional measurement can be performed by default.
[0076] It should be noted that the beam spacing between adjacent target beams differs for target beams in different dimensions. For example, the beam spacing between target beams corresponding to different codebooks can be a separate azimuth beam spacing (denoted as O1, where O1 = 1 when the beam spacing is the same as that of orthogonal beams), a separate elevation beam spacing (denoted as O2, where O2 = 1 when the beam spacing is the same as that of orthogonal beams), or separate beam spacings for the azimuth and elevation dimensions (denoted as O1 and O2 respectively). If only one beam spacing is indicated, it can be assumed to be the azimuth beam spacing (O1) or a beam spacing shared by both azimuth and elevation dimensions (O1 and O2). Furthermore, this information can be omitted, defaulting to the beam spacing between orthogonal beams, i.e., O1 = 1, O2 = 1, or other corresponding values, such as O1 = 2, O2 = 2, indicating that the spacing between two adjacent target beams is half the beam spacing of the orthogonal beams.
[0077] Taking two-dimensional measurement as an example, the signal conditioning device can draw the following conclusion from the various pieces of information in the codebook indication information: the indicated reference codebook number B id The beam spacing between adjacent target beams is the beam spacing corresponding to orthogonal beams (O1=1, O2=1), indicating the target beam. In other words, the number of codebooks corresponding to the target beam is 5, meaning the base station transmits 5 codebooks to the signal conditioning device, with corresponding codebook numbers B. id B id Orthogonal left beam (azimuth dimension), B id Orthogonal right beam (azimuth dimension), B id Orthogonal upper beam (elevation dimension) and B id The orthogonal lower beam (elevation dimension) has a beam spacing of the target beam corresponding to each codebook, which is the spacing corresponding to the orthogonal beam.
[0078] In one embodiment of this application, step S110 is further described. Step S110 may include, but is not limited to, step S111.
[0079] Step S111: Receive the target reference signal from the transmitting device in the target time slot.
[0080] In this step, since the terminal sends the target reference signal in its corresponding target time slot, that is, the signal in the target time slot is the target reference signal, the target reference signal from the terminal can be accurately received in the target time slot. Therefore, there will be no target reference signal reception error, so that the subsequent steps can be executed normally.
[0081] It should be noted that the specific form of the target time slot can be implemented in different ways, and no specific limitation is made here. For example, it can be a time slot measured in hours, minutes, days, weeks, etc. In other words, the specific form of the target time slot can be set according to different application scenarios or different terminals and signal conditioning devices, and no specific limitation is made here.
[0082] In one embodiment of this application, step S120 is further described, and step S120 may include, but is not limited to, step S121.
[0083] Step S121: Use one of the multiple first codebooks as the target codebook to send the target reference signal to the receiving device.
[0084] In this step, one of the multiple first codebooks is selected as the target codebook, and the target reference signal is sent to the base station using one of the multiple first codebooks as the target codebook, so that the base station can determine the position of the transmitting device relative to the signal conditioning device based on the signal characteristics of the target reference signal.
[0085] It should be noted that within the effective time range of the target codebook, the signal conditioning device can use the target codebook to send the target reference signal to the base station. In other words, once the target reference signal leaves the signal conditioning device, the target codebook no longer applies to the target reference signal. Therefore, there will be no situation where other signals are mistakenly sent to the base station through the corresponding target beam, which can ensure the accuracy of the target reference signal transmission.
[0086] It should be noted that the timing of the signal conditioning device sensing the arrival or departure of the target reference signal can be implemented in different ways, and no specific limitation is made here. For example, a signal sensing structure can be pre-installed on the signal conditioning device to sense the presence of the target reference signal, thereby determining the timing of the arrival or departure of the target reference signal; another example is that the operator monitors the flow rate of the signal conditioning device in real time and determines the timing of the arrival or departure of the target reference signal based on the flow rate of the signal conditioning device.
[0087] One embodiment of this application may include, but is not limited to, step S140.
[0088] Step S140: Receive signal indication information.
[0089] It should be noted that the signal indication information is used to instruct the terminal to send the target reference signal in the target time slot.
[0090] In this step, since the signal indication information can instruct the terminal to send the target reference signal in the target time slot, the transmission time slot of the target reference signal can be known by receiving the signal indication information, so that the target reference signal can be accurately received in the target time slot.
[0091] In some embodiments, signal indication information can also be used to instruct the terminal to transmit a target reference signal based on other air interface resources besides the target time slot, such as OFDM symbols.
[0092] It should be noted that since the signal conditioning device may be connected to multiple communication devices (such as multiple terminals) simultaneously, it can receive multiple signals at the same time. To prevent signal identification mismatches, signal indication information is set so that the signal conditioning device can determine the target reference signal sent by the terminal based on the signal indication information. This can greatly improve the transmission accuracy of the target reference signal. For example, the base station configures an uplink target reference signal with a codebook of 5. The target reference signal is distributed across 5 OFDM symbols, with 1 target reference signal per OFDM symbol. After the configuration is completed, the base station can send the time slot and OFDM symbol distribution of the uplink target reference signal as signal indication information to the signal conditioning device. This allows the signal conditioning device to identify the signal as the target reference signal based on the time slot and OFDM symbol distribution of the uplink target reference signal when it receives a signal from the terminal.
[0093] It should be noted that, regardless of the number of target beams, the signal conditioning device can perform the above step S120 for each target beam. That is, the signal conditioning device can accurately send the target reference signal to the base station using the target codebook so that the base station can perform subsequent measurements.
[0094] It should be noted that the receiving of codebook indication information and signal indication information can be implemented in different ways, and no specific limitation is made here. For example, the codebook indication information and / or signal indication information can be received when codebook indication information and / or signal indication information sent by the base station is detected; or, the receiving of codebook indication information and / or signal indication information can be pre-negotiated and determined before executing step S110, so that when preset conditions are met, such as reaching a specified time, the codebook indication information and / or signal indication information can be received from the base station.
[0095] It should be noted that the source of codebook indication information and / or signal indication information can be various, such as base stations or preset information transmission devices. When the source is a base station, the above information can be instantaneous information periodically sent by the base station during peak network traffic periods, or average information sent by the base station within a preset time period during peak network traffic periods, or other types of information, which are not specifically limited here.
[0096] It should be noted that in this embodiment, the base station determines the position of the terminal relative to the signal conditioning device based on the signal characteristics of the target reference signal. Specific details, including the signal characteristics of the target reference signal, will be provided in subsequent embodiments and will not be elaborated here.
[0097] It should be noted that the terminal can also be instructed to send a target reference signal, so that it can send the corresponding target reference signal according to the instruction. This can be set according to the specific scenario. For example, it can be preset to a base station or other similar signal transmitting device. Taking a base station as an example, the base station configures an uplink reference signal instruction information to the terminal. The uplink reference signal instruction information is sent by the base station to the terminal, so that the terminal sends the target reference signal to the signal conditioning device according to the information.
[0098] In one embodiment of this application, when the signal conditioning device is a RIS and the RIS has at least one element, step S120 is further described. Step S120 may include, but is not limited to, step S122.
[0099] Step S122: Adjust at least one element according to the target codebook, so that RIS uses the target beam corresponding to the target codebook to send the target reference signal to the receiving device.
[0100] In this step, since the RIS can be a passive device, the RIS adjusts at least one element according to the target codebook, so that the RIS can determine the target beam corresponding to the target codebook, and thus the RIS sends the target reference signal to the base station through the target beam.
[0101] It should be noted that there are different implementation methods for adjusting the RIS, and no specific limitation is made here. For example, if the difference between the target beam characteristics and the current RIS lies in the phase value, then by adjusting the phase value of the electromagnetic units of the RIS (e.g., varactor diodes, PIN switches, MEMS switches, liquid crystals, graphene, etc.), the RIS can transmit the target reference signal to the base station through the target beam. Similarly, if the difference between the target beam characteristics and the current RIS lies in the angle value, amplitude, etc., then similar adjustments can be made to the electromagnetic units of the RIS, which will not be detailed here.
[0102] In addition to the signal conditioning device being a RIS, when the signal conditioning device is a repeater, since the repeater is a relay for forwarding signals, the repeater can also generate a target beam corresponding to the target codebook based on the target codebook, and then use the target beam to send a target reference signal to the base station, so that the base station can receive the target reference signal and determine the position of the terminal relative to the signal conditioning device based on the target reference signal, thereby improving the accuracy of measuring the position of the terminal.
[0103] It should be noted that there are different implementation methods for generating the corresponding target beam based on the target codebook, and no specific limitation is made here. For example, when the operator or the repeater itself enters the target codebook, the repeater can directly generate the target beam based on the target codebook; or, the repeater can pre-store the program code or application flow for generating the target beam based on the target codebook. When the repeater is started or the repeater's signal receiving function is triggered, that is, when it is detected that the repeater has selected the target codebook, the repeater reads the pre-stored program code or application flow to generate the target beam.
[0104] like Figure 6 As shown, Figure 6 This is a flowchart of a position measurement method provided in another embodiment of this application. This position measurement method can be applied to a signal conditioning device, such as... Figure 1 The signal conditioning device 120 in the illustrated embodiment. The position measurement method may include, but is not limited to, steps S210 and S220.
[0105] Step S210: Receive the target reference signal.
[0106] It should be noted that the source of the target reference signal is not limited and can be selected according to the specific application scenario. For example, the transmitting device can send the target reference signal to the signal conditioning device, meaning that the signal conditioning device receives the target reference signal from the transmitting device.
[0107] It should be noted that the execution subjects of steps S210 and S110 are both signal conditioning devices, which have the same technical concept and can be regarded as substantially equivalent invention content. Therefore, the specific implementation method and working principle of step S210 are similar to those of step S110. Since the specific implementation method and working principle of step S110 have been described in detail above, the specific implementation method and working principle of step S210 can be obtained by referring to the description of the specific implementation method and working principle of step S110. To avoid redundancy, they will not be described in detail here.
[0108] In one embodiment of this application, step S210 is further described. Step S210 may include, but is not limited to, step S211.
[0109] Step S211: Receive the target reference signal in the target time slot.
[0110] In this step, since the signal transmitted in the target time slot is the target reference signal, the target reference signal can be accurately received in the target time slot, so there will be no error in receiving the target reference signal, so that the subsequent steps can be executed normally.
[0111] It should be noted that the specific form of the target time slot can be implemented in different ways, and no specific limitation is made here. For example, it can be a time slot measured in hours, minutes, days, weeks, etc. In other words, the specific form of the target time slot can be set according to different application scenarios or different terminals and signal conditioning devices, and no specific limitation is made here.
[0112] Step S220: Use the target codebook to send the target reference signal to the receiving device.
[0113] It should be noted that the target codebook is used to adjust the beam of the signal received by the signal conditioning device to the beam corresponding to the target codebook, and the signal characteristics of the target reference signal are used to determine the position of the receiving device relative to the signal conditioning device.
[0114] It should be noted that the signal characteristics of the target reference signal include the main lobe phase of the target reference signal detected by the receiving device.
[0115] It should be noted that the receiving device in this embodiment may be, but is not limited to, [a specific type of device]. Figure 1In the illustrated embodiment, the target reference signal for the terminal 130 is, correspondingly, the uplink target reference signal; or, those skilled in the art can choose to set up a corresponding receiving device according to the actual application scenario, and this embodiment does not impose any restrictions. To more conveniently describe the application scenarios and principles of this application, the following related embodiments use a terminal as the receiving device, but this should not be construed as a limitation on the embodiments of this application.
[0116] In this step, since the target reference signal is received in step S210, the target codebook can be used to send the target reference signal to the terminal in step S220. Then, the position of the terminal relative to the signal conditioning device can be determined based on the signal characteristics of the target reference signal. In other words, the target reference signal can be accurately sent to the terminal in the form of a beam corresponding to the target codebook for subsequent position measurement. Unlike related technologies, position measurement can be performed based on the signal characteristics of the detected target reference signal, thus avoiding position measurement based on distance or time delay. This reduces the stringent requirements for time delay and the amplitude of RF devices, achieving the goal of optimizing the measurement method and saving measurement costs. Therefore, the embodiments of this application can easily and effectively achieve target position measurement while saving measurement costs. Furthermore, based on the measured target position signal, its far-field and near-field characteristics relative to the signal conditioning device can be determined, facilitating more accurate overall communication design and filling the technological gap in related measurement methods.
[0117] It should be noted that the signal conditioning device in this embodiment is configured with multiple first codebooks, and the target codebook is one of the multiple first codebooks; the signal conditioning device can select one of the multiple first codebooks as the target codebook to send the target reference signal to the terminal.
[0118] One embodiment of this application may include, but is not limited to, step S230.
[0119] Step S230: Receive codebook instruction information.
[0120] In one feasible implementation, the codebook indication information includes at least one of the following:
[0121] A codebook number;
[0122] The beam spacing between adjacent target beams, where the target beams are multiple beams corresponding to multiple first codebooks;
[0123] The number of target beams;
[0124] Measurement of azimuth indication information.
[0125] In this step, codebook indication information is received so that in subsequent steps, one of the multiple first codebooks can be selected as the target codebook based on the codebook indication information.
[0126] It should be noted that the composition of multiple first codebooks can vary depending on the application scenario. For example, multiple first codebooks may have the same weights in the elevation dimension, or multiple first codebooks may have the same weights in the azimuth dimension; or multiple first codebooks may consist of two parts, where the first part has the same weights in the azimuth dimension and the second part has the same weights in the elevation dimension; or multiple first codebooks may include a pair of identical first codebooks used for Doppler compensation.
[0127] It should be noted that the execution entities of steps S230 and S130 are both signal conditioning devices, which have the same technical concept and can be regarded as substantially equivalent inventive contents. Therefore, the specific implementation method and working principle of step S230 are similar to those of step S130. That is to say, the specific implementation methods of codebook indication information, target beam, multiple first codebooks and measurement azimuth indication information in step S230 are similar to those in step S130. Since the specific implementation method and working principle of step S130 have been described in detail above, the specific implementation method and working principle of step S230 can be obtained by referring to the description of the specific implementation method and working principle of step S130. To avoid redundancy, they will not be described in detail here.
[0128] In one embodiment of this application, step S220 is further described, and step S220 may include, but is not limited to, step S221.
[0129] Step S221: Use one of the multiple first codebooks as the target codebook to send the target reference signal to the receiving device.
[0130] In this step, the target reference signal is sent to the terminal by selecting one of the multiple first codebooks as the target codebook.
[0131] It should be noted that within the effective time range of the target codebook, the signal conditioning device can use the target codebook to send the target reference signal to the terminal. In other words, once the target reference signal leaves the signal conditioning device, the target codebook no longer acts on the target reference signal. Therefore, there will be no situation where other signals are mistakenly sent to the terminal through the corresponding target beam, which can ensure the accuracy of the target reference signal transmission.
[0132] One embodiment of this application may include, but is not limited to, step S240.
[0133] Step S240: Receive signal indication information.
[0134] It should be noted that the signal indication information is used to instruct the transmitting device to transmit the target reference signal in the target time slot. It should also be noted that the transmitting device in this embodiment may be, but is not limited to, [a specific type of device]. Figure 1 In the illustrated embodiment, the target reference signal for the base station 110 is, correspondingly, a downlink target reference signal; or, those skilled in the art can choose to set up a corresponding transmitting device according to the actual application scenario, and this embodiment does not impose any restrictions. To more conveniently describe the application scenarios and principles of this application, the following related embodiments use a base station as the transmitting device, but this should not be construed as a limitation on the embodiments of this application.
[0135] In some embodiments, the signal indication information can also be used to instruct the base station to transmit a target reference signal based on other air interface resources besides the target time slot, such as OFDM symbols.
[0136] In this step, since the signal indication information can instruct the base station to send the target reference signal in the target time slot, the transmission time slot of the target reference signal can be known by receiving the signal indication information, so that the target reference signal sent by the base station can be accurately received in the target time slot.
[0137] It should be noted that since the signal conditioning device may be connected to multiple communication devices simultaneously, it can receive multiple signals at the same time. To prevent signal identification mismatches, signal indication information is set so that the signal conditioning device can determine that it has received the target reference signal sent by the base station based on the signal indication information. This can greatly improve the transmission accuracy of the target reference signal. For example, the base station configures a downlink target reference signal with a codebook of 5, which is distributed across 5 OFDM symbols. Each OFDM symbol corresponds to one target reference signal. After the configuration is completed, the base station can send the time slot, OFDM symbol distribution, etc. of the uplink target reference signal as signal indication information to the signal conditioning device, so that the signal conditioning device can identify the signal as the target reference signal based on the time slot, OFDM symbol distribution, etc.
[0138] It should be noted that the signal characteristics of the target reference signal in this embodiment, used to determine the position of the terminal relative to the signal conditioning device, and other related details will be given in subsequent embodiments and will not be described here.
[0139] It should be noted that an indication of a target reference signal can also be sent to the terminal, enabling it to confirm the target reference signal based on the indication. This can be set according to the specific scenario. For example, it can be preset to a base station or other similar signal transmitting device. Taking a base station as an example, the base station configures a downlink reference signal indication information to the terminal. This downlink reference signal indication information is sent by the base station to the terminal, so that the terminal can confirm the signal sent by the signal conditioning device as the target reference signal based on this information.
[0140] In one embodiment of this application, when the signal conditioning device is a RIS and the RIS has at least one element, step S220 is further described. Step S220 may include, but is not limited to, step S222.
[0141] Step S222: Adjust at least one element according to the target codebook, so that the RIS uses the target beam corresponding to the target codebook to send the target reference signal to the receiving device.
[0142] In this step, since the RIS can be a passive device, the RIS adjusts at least one element according to the target codebook, so that the RIS can determine the target beam corresponding to the target codebook, and thus the RIS sends the target reference signal to the terminal through the target beam.
[0143] It should be noted that there are different implementation methods for adjusting the RIS, and no specific limitation is made here. For example, if the difference between the target beam characteristics and the current RIS lies in the phase value, then by adjusting the phase value of the electromagnetic units of the RIS (e.g., varactor diodes, PIN switches, MEMS switches, liquid crystals, graphene, etc.), the RIS can transmit the target reference signal to the terminal through the target beam. Similarly, if the difference between the target beam characteristics and the current RIS lies in the angle value, amplitude, etc., then similar adjustments can be made to the electromagnetic units of the RIS, which will not be detailed here.
[0144] In addition to the signal conditioning device being a RIS, when the signal conditioning device is a repeater, since the repeater is a relay for forwarding signals, the repeater can also generate a target beam corresponding to the target codebook based on the target codebook, and then use the target beam to send a target reference signal to the terminal so that the terminal can receive the target reference signal.
[0145] like Figure 7 As shown, Figure 7 This is a flowchart of a position measurement method provided in another embodiment of this application. This position measurement method can be applied to a receiving device, for example... Figure 1The illustrated embodiment includes a base station 110. This power measurement method can be applied to scenarios where the base station is operating normally and network traffic is at its peak. The location measurement method may include, but is not limited to, steps S310 and S320.
[0146] Step S310: Receive the target reference signal.
[0147] It should be noted that the target reference signal is received from the transmitting device by the signal conditioning device and transmitted to the receiving device using the target codebook. The target codebook is used by the signal conditioning device to adjust the beam of the received signal to the beam corresponding to the target codebook.
[0148] In this step, a target reference signal is received from the transmitting device by the signal conditioning device and transmitted using the target codebook, so that the position of the transmitting device relative to the signal conditioning device can be determined in subsequent steps based on the signal characteristics of the target reference signal.
[0149] It should be noted that the transmitting device in this embodiment may be, but is not limited to, [the following]. Figure 1 The terminal 130 in the illustrated embodiment, and the receiving device in this embodiment, may be, but is not limited to, a terminal 130. Figure 1 In the illustrated embodiment, the target reference signal for the base station 110 is, correspondingly, the uplink target reference signal; or, those skilled in the art can choose to set up the corresponding transmitting or receiving device according to the actual application scenario, and this embodiment does not impose any restrictions. In order to more conveniently describe the application scenario and principle of this application, the following related embodiments are described with the terminal as the transmitting device and the base station as the receiving device, but they should not be construed as limitations on the embodiments of this application.
[0150] It should be noted that step S310 and step S110 have the same technical concept, the only difference being the different implementing entities. They can be regarded as substantially equivalent inventive content. Therefore, the specific implementation method and working principle of step S310 are similar to those of step S110. Since the specific implementation method and working principle of step S110 have been described in detail above, the specific implementation method and working principle of step S310 can be obtained by referring to the description of the specific implementation method and working principle of step S110. To avoid redundancy, they will not be described in detail here.
[0151] Step S320: Determine the position of the transmitting device relative to the signal conditioning device based on the signal characteristics of the detected target reference signal.
[0152] It should be noted that the signal characteristics of the target reference signal include the main lobe phase of the target reference signal detected by the receiving device.
[0153] In this step, since the target reference signal is received in step S310, the position can be measured in step S320 based on the signal characteristics of the detected target reference signal. Therefore, position measurement based on distance or time delay can be avoided, thereby reducing the stringent requirements for time delay and the amplitude and phase of RF devices, achieving the goal of optimizing the measurement method and saving measurement costs. Therefore, the embodiments of this application can easily and effectively measure the position of the target while saving measurement costs. Furthermore, based on the measured target position signal, its far-field and near-field characteristics relative to the signal conditioning device can be determined, facilitating more accurate overall communication design and filling the technical gaps in related measurement methods.
[0154] One embodiment of this application may include, but is not limited to, step S330.
[0155] Step S330: Send codebook indication information to the signal conditioning device.
[0156] In one feasible implementation, the codebook indication information includes at least one of the following:
[0157] A codebook number;
[0158] The beam spacing between adjacent target beams, where the target beams are multiple beams corresponding to multiple first codebooks;
[0159] The number of target beams;
[0160] Measurement of azimuth indication information.
[0161] In this step, codebook indication information is sent to the signal conditioning device so that in subsequent steps, the signal conditioning device can select one of multiple first codebooks as the target codebook based on the codebook indication information, and then use one of the multiple first codebooks as the target codebook to send the target reference signal to the base station.
[0162] It should be noted that the composition of multiple first codebooks can vary depending on the application scenario. For example, multiple first codebooks may have the same weights in the elevation dimension, or multiple first codebooks may have the same weights in the azimuth dimension; or multiple first codebooks may consist of two parts, where the first part has the same weights in the azimuth dimension and the second part has the same weights in the elevation dimension; or multiple first codebooks may include a pair of identical first codebooks used for Doppler compensation.
[0163] It should be noted that, since the codebook indication information, target beam, multiple first codebooks and measurement azimuth indication information have been described in detail in the foregoing embodiments, they will not be described in detail here to avoid redundancy.
[0164] One embodiment of this application may include, but is not limited to, step S340.
[0165] Step S340: Send signal indication information to the signal conditioning device.
[0166] It should be noted that the signal indication information is used to instruct the transmitting device to send the target reference signal in the target time slot.
[0167] In some embodiments, signal indication information can also be used to instruct the terminal to transmit a target reference signal based on other air interface resources besides the target time slot, such as OFDM symbols.
[0168] In this step, since the signal indication information can instruct the terminal to send the target reference signal in the target time slot, by sending the signal indication information to the signal conditioning device, the signal conditioning device can know the transmission time slot of the target reference signal, so as to accurately receive the target reference signal sent by the terminal in the target time slot.
[0169] It should be noted that since the signal conditioning device may be connected to multiple communication devices at the same time, it can receive multiple signals simultaneously. In order to prevent signal identification mismatch, signal indication information is set so that the signal conditioning device can determine the target reference signal sent by the terminal based on the signal indication information, which can greatly improve the reception accuracy of the target reference signal.
[0170] It should be noted that the base station can also send a target reference signal indication to the terminal, so that the terminal can confirm the target reference signal according to the indication. This can be set according to the specific scenario. For example, it can be preset to be a base station or other similar signal transmitting device. Taking the base station as an example, the base station configures a downlink reference signal indication information to the terminal. This downlink reference signal indication information is sent by the base station to the terminal, so that the terminal can confirm the signal sent by the signal conditioning device as the target reference signal according to the indication information.
[0171] It should be noted that the information exchange between the base station, the terminal, and the signal conditioning device can be configured according to the actual scenario and is not limited here. For example, the base station can roughly estimate the relative distance between the terminal and the base station or between the terminal and the signal conditioning device based on historical stored data, and then send the corresponding information to the terminal or the signal conditioning device according to the estimated relative distance.
[0172] Reference Figure 8 As shown in the embodiment of this application, step S320 will be further described. Step S320 may include, but is not limited to, steps S321 to S323.
[0173] Step S321: Calculate the primary phase parameter and the secondary phase parameter based on the main lobe phase of the target reference signal.
[0174] In this step, since the main lobe phase of the target reference signal can be well approximated as a secondary phase in space, the primary and secondary phase parameters with high accuracy can be calculated based on the main lobe phase of the target reference signal. This allows the terminal's position coordinates to be calculated based on the obtained primary and secondary phase parameters in subsequent steps, and the terminal's position relative to the signal conditioning device to be determined based on the terminal's position coordinates.
[0175] It should be noted that there are various ways to calculate the primary and secondary phase parameters based on the target reference signal, and there is no limitation here. The following is only one specific implementation method to illustrate the principle and process of the method. For those skilled in the art, adaptive adjustments made based on this implementation method in specific scenarios are also within the protection scope of this implementation method.
[0176] Since the multiple beams of the target or terminal relative to the signal conditioning device under near-field conditions can be a linear frequency modulated signal, and the parameters of the linear frequency modulated signal vary depending on the position of the target or terminal, the position of the target or terminal relative to the signal conditioning device under near-field conditions can be determined based on this.
[0177] Reference Figure 9 The signal conditioning device is RIS. The RIS elements are distributed on the X-axis. The coordinates of the elements are (x,0) and the coordinates of the terminals are (x0,y0). The distance R(x) between the elements (x,0) and the terminals (x0,y0) can be simplified and calculated using the following formula (1).
[0178]
[0179] Based on formula (1), considering the simplification and neglect of the radiation pattern of the strobe, the signal received by the strobe (x,0) can be calculated by the following formula (2).
[0180]
[0181] In formula (2), λ is the wavelength of the carrier signal.
[0182] According to formula (2), the signal received by the strobe on the X-axis is a linear frequency modulated signal with respect to x. Different beam directions are equivalent to the spatial Fourier transform with respect to x. The spatial Fourier transform of formula (2) is solved using the stationary phase principle, and the following formula (3) is set:
[0183]
[0184] make The following formula (4) can be obtained.
[0185]
[0186] Then, combining formulas (2), (3) and (4) as shown above, the spatial Fourier transform of formula (2) can be expressed as formula (5) below.
[0187]
[0188] In formula (5), the spatial angle between the terminal and the signal conditioning device is defined as... Then ω and The relationship between them can be calculated using the following formula (6).
[0189]
[0190] Combining formulas (5) and (6), we can obtain formula (7) for the spatial angle between the received signal, the terminal, and the signal conditioning device.
[0191]
[0192] In formula (7), Let A be the target reference signal, and A be a complex parameter. For a first-order phase parameter, For the second phase parameter, Let x0 be the spatial angle between the terminal and the signal conditioning device, and y0 be the first position coordinate and y0 be the second position coordinate.
[0193] According to formula (7), the signal received by the signal conditioning device is... Given a linear frequency modulated signal, its phase value is about The second phase, if obtained by changing the codebook of different signal conditioning devices, can be obtained in multiple different ways. For the corresponding target beam, x0 and y0 can be estimated using the main lobe phase of the target reference signal. y0 is related to the second phase coefficient, and x0 is related to the first phase coefficient. The estimated x0 and y0 can be used to determine the position of the terminal relative to the signal conditioning device, thus effectively determining the near-field and far-field characteristics of the terminal.
[0194] The relationship between the phase of the target beam and the center angle of the corresponding codebook measured by the terminal and signal conditioning device under different distance conditions is as follows: Figure 10 As shown, from Figure 10 As can be seen, different distance conditions correspond to different quadratic phase coefficients, and the variation between the two contributes to the fact that distance can be determined.
[0195] It should be noted that when the distance in the normal direction of the terminal offset signal adjustment device is large, that is, in In many cases, the accuracy of the second expansion using only formula (2) is not high, and a higher order expansion may be required. However, this does not affect the specific principle of the present invention. That is, the corresponding calculation can still be performed according to the principle of this embodiment. In this process, relevant computer software can be used to perform derivation calculations based on algorithms, or those skilled in the art can choose an adaptive calculation method to perform the calculation. This is not limited here.
[0196] It should be noted that, referring to Figure 11 , Figure 11 The diagram shows the relationship between the theoretically calculated beam phase and the beam phase approximated using the stationary phase principle under near-field conditions, and between the beam phase and angle. Figure 11 As can be seen from the simulation results, the theoretically calculated beam phase value and the beam phase value approximated by the stationary phase principle are highly consistent in the main lobe direction. Therefore, it can be considered that the theoretical beam in the main lobe direction is almost equivalent to the second phase of the spatial angle. The simulation results also confirm the accuracy of the results of this specific implementation in the actual application scenario. In other words, by using the signal characteristics of the target reference signal as the main lobe phase of the target reference signal for calculation, a coordinate measurement result with relatively high accuracy can be obtained.
[0197] Step S322: Calculate the first and second position coordinates of the terminal based on the primary and secondary phase parameters.
[0198] In this step, the first position coordinate and the second position coordinate of the terminal can be calculated by formula (7) derived above. That is to say, by formula (7), it can be known that each target reference signal can be obtained with corresponding primary phase parameters and secondary phase parameters. When there are multiple target reference signals, multiple sets of primary phase parameters and secondary phase parameters can be obtained. Based on multiple sets of primary phase parameters and secondary phase parameters, combined with formula (7), the first position coordinate x0 and the second position coordinate y0 of the terminal can be calculated.
[0199] In a feasible implementation, when the measurement azimuth indication information in the codebook indication information is one-dimensional indication information, that is, indication information for performing azimuth measurement or indication information for performing pitch measurement, according to the calculation content disclosed in the aforementioned implementation, a primary phase coefficient and a secondary phase coefficient can be obtained for both azimuth measurement and pitch measurement. Under the condition that other conditions remain the same, it can be determined that the secondary phase coefficients corresponding to azimuth measurement and pitch measurement are the same.
[0200] In another feasible implementation, when the measurement orientation indication information in the codebook indication information is two-dimensional indication information, that is, indication information for performing two-dimensional measurements in the azimuth and pitch directions, according to the calculation content disclosed in the aforementioned implementation, the azimuth measurement can calculate a primary phase coefficient and a secondary phase coefficient, and the pitch measurement can also calculate a primary phase coefficient and a secondary phase coefficient. In other words, when indicating two-dimensional measurement, at least two sets of phase coefficient data can be calculated. In this case, the two sets of phase coefficients can be input into the above formula (7) to calculate the first position coordinates and the second position coordinates of the terminal in the two-dimensional measurement scenario.
[0201] In another feasible implementation, as indicated in the foregoing embodiments, in some specific application scenarios, formula (7) can be expanded to a higher order to calculate multiple position coordinates based on more determined phase coefficients. This still falls within the protection scope of the embodiments of this application. For example, when the measurement azimuth indication information in the codebook indication information is two-dimensional indication information, that is, indication information for performing two-dimensional measurements in the azimuth and elevation directions, according to the calculation content disclosed in the foregoing embodiments, the azimuth measurement can calculate one primary phase coefficient and one secondary phase coefficient, and the elevation measurement can also calculate one primary phase coefficient and one secondary phase coefficient. The secondary phase coefficients of the azimuth and elevation directions are equal. That is, when indicating two-dimensional measurement, two primary phase coefficients and one secondary phase coefficient can be calculated, which is equivalent to obtaining three sets of phase coefficient data. In this case, the three sets of phase coefficients can be input into the formula (7) after higher-order expansion to calculate the first position coordinate, second position coordinate, and third position coordinate of the terminal in the two-dimensional measurement scenario.
[0202] Step S323: Determine the position of the transmitting device relative to the signal conditioning device based on the first position coordinates and the second position coordinates.
[0203] In this step, when the first position coordinate x0 and the second position coordinate y0 of the terminal are calculated according to formula (7), the actual position of the terminal can be determined. Combined with the pre-determined position information of the signal conditioning device, the position of the terminal relative to the signal conditioning device can be accurately measured.
[0204] It should be noted that the location information of the signal conditioning device can be predetermined by the base station. For example, the base station sends a location query signal to the signal conditioning device, and after receiving the location query signal, the signal conditioning device sends back feedback information about the location query signal to the base station. The location information of the signal conditioning device can also be further configured by the operator. For example, the operator can set a response in advance at the signal conditioning device, and after confirming that the location query signal has been received, the operator can query its own location based on the location query signal.
[0205] like Figure 12 As shown, Figure 12 This is a flowchart of a position measurement method provided in another embodiment of this application. This position measurement method can be applied to a transmitting device, for example... Figure 1 The illustrated embodiment includes a base station 110. This power measurement method can be applied to scenarios where the base station is operating normally and network traffic is at its peak. The location measurement method may include, but is not limited to, steps S410, S420, and S430.
[0206] Step S410: Send a target reference signal to the signal conditioning device, so that the signal conditioning device uses the target codebook to send the target reference signal to the receiving device.
[0207] It should be noted that the target codebook is used by the signal conditioning device to adjust the beam of the received signal to the beam corresponding to the target codebook.
[0208] It should be noted that the transmitting device in this embodiment may be, but is not limited to, [the following]. Figure 1 The base station 110 in the illustrated embodiment, and the receiving device in this embodiment may be, but is not limited to, a base station 110. Figure 1 In the illustrated embodiment, the terminal 130 corresponds to the downlink target reference signal for the base station; alternatively, those skilled in the art can choose to set up a corresponding transmitting or receiving device according to the actual application scenario, and this embodiment does not impose any restrictions. To more conveniently describe the application scenarios and principles of this application, the following related embodiments use the base station as the transmitting device and the terminal as the receiving device, but this should not be construed as a limitation on the embodiments of this application.
[0209] In this step, by sending a target reference signal to the signal conditioning device, the signal conditioning device uses the target codebook to send the target reference signal to the terminal, so that in subsequent steps the terminal can generate a target measurement signal based on the signal characteristics of the target reference signal and send the target measurement signal to the base station.
[0210] It should be noted that step S410 and step S210 have the same technical concept, the only difference being the different implementing entities. They can be regarded as substantially equivalent inventive contents. Therefore, the specific implementation method and working principle of step S410 are similar to those of step S210. Since the specific implementation method and working principle of step S210 have been described in detail above, the specific implementation method and working principle of step S410 can be obtained by referring to the description of the specific implementation method and working principle of step S210. To avoid redundancy, they will not be described in detail here.
[0211] Step S420: Receive the target measurement signal sent by the receiving device.
[0212] It should be noted that the target measurement signal is obtained by the terminal based on the signal characteristics of the target reference signal.
[0213] It should be noted that the signal characteristics of the target reference signal include the main lobe phase of the target reference signal detected by the terminal.
[0214] In this step, the base station receives the target measurement signal sent by the terminal so that the position of the terminal relative to the signal conditioning device can be measured in subsequent steps based on the received target measurement signal.
[0215] It should be noted that the specific method of obtaining the target measurement signal is not limited. Those skilled in the art can calculate it based on the target reference signal in a specific scenario. The following will provide a specific implementation method for its description, which will not be described here.
[0216] Step S430: Determine the position of the receiving device relative to the signal conditioning device based on the target measurement signal.
[0217] In this step, since the base station has already received the target measurement signal in step S420, the base station can measure the position of the terminal relative to the signal conditioning device based on the target measurement signal.
[0218] It should be noted that since the target measurement signal is obtained by the receiving device based on the signal characteristics of the target reference signal, the base station can perform position measurement based on the signal characteristics of the detectable target reference signal. Therefore, position measurement based on distance or time delay can be avoided, thereby reducing the stringent requirements for time delay and the amplitude and phase of radio frequency devices, achieving the goal of optimizing the measurement method and saving measurement costs. Thus, the embodiments of this application can easily and effectively achieve target position measurement while saving measurement costs. Furthermore, based on the measured target position signal, its far-field and near-field characteristics relative to the signal conditioning device can be determined, facilitating more accurate overall communication design and filling the technical gaps in related measurement methods.
[0219] One embodiment of this application may include, but is not limited to, step S440.
[0220] Step S440: Send codebook indication information to the signal conditioning device.
[0221] In one feasible implementation, the codebook indication information includes at least one of the following:
[0222] A codebook number;
[0223] The beam spacing between adjacent target beams, where the target beams are multiple beams corresponding to multiple first codebooks;
[0224] The number of target beams;
[0225] Measurement of azimuth indication information.
[0226] In this step, codebook indication information is sent to the signal conditioning device so that in subsequent steps, the signal conditioning device can select one of the multiple first codebooks as the target codebook based on the codebook indication information, and then use one of the multiple first codebooks as the target codebook to send the target reference signal to the terminal.
[0227] It should be noted that the composition of multiple first codebooks can vary depending on the application scenario. For example, multiple first codebooks may have the same weights in the elevation dimension, or multiple first codebooks may have the same weights in the azimuth dimension; or multiple first codebooks may consist of two parts, where the first part has the same weights in the azimuth dimension and the second part has the same weights in the elevation dimension; or multiple first codebooks may include a pair of identical first codebooks used for Doppler compensation.
[0228] It should be noted that, since the codebook indication information, target beam, multiple first codebooks and measurement azimuth indication information have been described in detail in the foregoing embodiments, they will not be described in detail here to avoid redundancy.
[0229] One embodiment of this application may include, but is not limited to, step S450.
[0230] Step S450: Send signal indication information to the signal conditioning device, so that the signal conditioning device sends the target reference signal to the receiving device in the target time slot using the target codebook according to the signal indication information.
[0231] In some embodiments, signal indication information can also be used to instruct the signal conditioning device to transmit a target reference signal based on other air interface resources besides the target time slot, such as OFDM symbols.
[0232] In this step, since the signal indication information can instruct the signal conditioning device to send the target reference signal in the target time slot, by sending the signal indication information to the signal conditioning device, the signal conditioning device can know the transmission time slot of the target reference signal, so that it can accurately send the target reference signal to the terminal in the target time slot.
[0233] It should be noted that the base station can also send a target reference signal indication to the terminal, so that the terminal can confirm the target reference signal according to the indication. This can be set according to the specific scenario. For example, it can be preset to be a base station or other similar signal transmitting device. Taking the base station as an example, the base station configures a downlink reference signal indication information to the terminal. This downlink reference signal indication information is sent by the base station to the terminal, so that the terminal can confirm the signal sent by the signal conditioning device as the target reference signal according to the indication information.
[0234] Reference Figure 13 As shown in the embodiment of this application, step S430 is further described. Step S430 may include, but is not limited to, steps S431, S432 and S433.
[0235] Step S431: Calculate the primary phase parameter and the secondary phase parameter based on the main lobe phase of the target reference signal.
[0236] In this step, since the main lobe phase of the target reference signal can be well approximated as a secondary phase in space, the primary and secondary phase parameters with high accuracy can be calculated based on the main lobe phase of the target reference signal. This allows the terminal's position coordinates to be calculated based on the obtained primary and secondary phase parameters in subsequent steps, and the terminal's position relative to the signal conditioning device to be determined based on the terminal's position coordinates.
[0237] Step S432: Calculate the first and second position coordinates of the terminal based on the primary and secondary phase parameters.
[0238] In this step, the first position coordinate and the second position coordinate of the terminal can be calculated by formula (7) derived above. That is to say, by formula (7), it can be known that each target reference signal can be obtained with corresponding primary phase parameters and secondary phase parameters. When there are multiple target reference signals, multiple sets of primary phase parameters and secondary phase parameters can be obtained. Based on multiple sets of primary phase parameters and secondary phase parameters, combined with formula (7), the first position coordinate x0 and the second position coordinate y0 of the terminal can be calculated.
[0239] Step S433: Determine the position of the receiving device relative to the signal conditioning device based on the first position coordinates and the second position coordinates.
[0240] In this step, when the first position coordinate x0 and the second position coordinate y0 of the terminal are calculated according to formula (7), the actual position of the terminal can be determined. Combined with the pre-determined position information of the signal conditioning device, the position of the terminal relative to the signal conditioning device can be accurately measured.
[0241] It should be noted that steps S431 to S433 and steps S321 to S323 have the same technical concept and the same implementing entity, and can be regarded as substantially equivalent inventive content. Therefore, the specific implementation methods and working principles of steps S431 to S433 are similar to those of steps S321 to S323. Since the specific implementation methods and working principles of steps S321 to S323 have been described in detail above, the specific implementation methods and working principles of steps S431 to S433 can be obtained by referring to the description of the specific implementation methods and working principles of steps S321 to S323. To avoid redundancy, they will not be described in detail here.
[0242] like Figure 14 As shown, Figure 14 This is a flowchart of a position measurement method provided in another embodiment of this application. This position measurement method can be applied to a receiving device, for example... Figure 1 The terminal 130 in the illustrated embodiment. The position measurement method may include, but is not limited to, steps S510, S520, and S530.
[0243] Step S510: Receive the target reference signal sent by the signal conditioning device using the target codebook.
[0244] It should be noted that the target codebook is used by the signal conditioning device to adjust the beam of the received signal to the beam corresponding to the target codebook.
[0245] In this step, the receiving device receives the target reference signal sent by the signal conditioning device using the target codebook, so that in subsequent steps, the target measurement signal can be further obtained based on the signal characteristics of the target reference signal and sent to the transmitting device.
[0246] It should be noted that the transmitting device in this embodiment may be, but is not limited to, [the following]. Figure 1 The base station 110 in the illustrated embodiment, and the receiving device in this embodiment may be, but is not limited to, a base station 110. Figure 1 In the illustrated embodiment, the terminal 130 corresponds to the uplink target reference signal for the base station; alternatively, those skilled in the art can choose to set up a corresponding transmitting or receiving device according to the actual application scenario, and this embodiment does not impose any restrictions. To more conveniently describe the application scenarios and principles of this application, the following related embodiments use the base station as the transmitting device and the terminal as the receiving device, but this should not be construed as a limitation on the embodiments of this application.
[0247] Step S520: Obtain the target measurement signal based on the signal characteristics of the detected target reference signal.
[0248] In this step, a target measurement signal is obtained based on the signal characteristics of the detected target reference signal, so that the target measurement signal can be sent to the base station in subsequent steps, enabling the base station to determine the position of the terminal relative to the signal conditioning device based on the target measurement signal.
[0249] Step S530: Send a target measurement signal to the transmitting device, so that the transmitting device determines the position of the receiving device relative to the signal conditioning device based on the target measurement signal.
[0250] In this step, the terminal sends a target measurement signal to the base station. Upon receiving the target measurement signal, the base station can measure the terminal's position relative to the signal conditioning device. This avoids relying on distance or time delay for position measurement, thus reducing stringent requirements on time delay and the amplitude and phase of radio frequency devices, achieving optimized measurement methods and cost savings. Therefore, this embodiment can easily and effectively measure the target's position while saving measurement costs. Based on the measured target position signal, its far-field and near-field characteristics relative to the signal conditioning device can be determined, facilitating more accurate overall communication design and filling a technological gap in related measurement methods.
[0251] It should be noted that steps S510 to S530 and steps S410 to S430 have the same technical concept, the only difference being the different implementing entities. They can be regarded as substantially equivalent inventive content. Therefore, the specific implementation methods and working principles of steps S510 to S530 are similar to those of steps S410 to S430. Since the specific implementation methods and working principles of steps S410 to S430 have been described in detail above, the specific implementation methods and working principles of steps S510 to S530 can be obtained by referring to the description of the specific implementation methods and working principles of steps S410 to S430. To avoid redundancy, they will not be described in detail here.
[0252] In one embodiment of this application, when the target measurement signal includes a primary phase parameter and a secondary phase parameter, step S520 is further described. Step S520 may include, but is not limited to, step S521.
[0253] Step S521: Calculate the primary phase parameter and the secondary phase parameter based on the main lobe phase of the target reference signal.
[0254] In this step, since the main lobe phase of the target reference signal can be spatially approximated as a secondary phase, the primary and secondary phase parameters with high accuracy can be calculated based on the main lobe phase of the target reference signal. This allows the phase parameters to be sent to the base station in subsequent steps, enabling the base station to calculate the terminal's position coordinates based on the obtained primary and secondary phase parameters, and determine the terminal's position relative to the signal conditioning device based on the terminal's position coordinates.
