[0033] In order to make the purpose, technical solution and advantages of the present disclosure more obvious, the exemplary embodiments according to the present disclosure will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure, and it should be understood that the present disclosure is not limited to the exemplary embodiments described here.
[0034] At present, in perception scenarios, an unambiguous speed of 100km / h is usually required. However, the current 2.5ms period of perception symbol cycle can only achieve an unambiguous speed of 22km / h, which is far lower than the expected 100km / h. In order to increase the unambiguous speed, it is necessary to increase the density of perception symbols, but doing so will increase the system overhead and even occupy 100% of the downlink overhead, which is unacceptable for a communication system with integrated interaesthesia. As a result, existing communication technologies cannot simultaneously meet the requirements of perception symbol accuracy and low system overhead, and it is difficult to meet the objective needs in actual use.
[0035] Therefore, the present application proposes a communication method, in which the sensing device dynamically adjusts the sensing symbol period according to the actual moving speed of the user equipment, which can improve the accuracy of the sensing symbol. At the same time, the interactive fine adjustment of the sensing symbol period by the sensing device and the communication device can reduce unnecessary resource consumption and reduce system overhead. Please refer to Figure 1 , Figure 1 The following is a schematic diagram of the architecture of a communication system provided by an embodiment of the present disclosure. Figure 1 As shown, the communication system at least includes: a sensing device and a communication device.
[0036] The sensing device can be understood as a device that can sense the user's moving speed, and can be a combination of sensing means such as radar, camera, etc. The sensing device can send sensing symbols and can establish communication with the communication device or user terminal.
[0037] Communication equipment can be understood as equipment for wireless communication. Communication equipment usually has at least one function such as high-speed data processing capability, powerful signal receiving and sending capability, and stable network connection capability. Communication equipment can establish communication with sensing devices or user terminals. Communication equipment includes but is not limited to at least one of the following: base station (such as cellular network base station), access point (such as Wi-Fi access point), relay station.
[0038] The embodiments of the present application have no particular restrictions on the specific technologies and specific device forms adopted by the sensing device and the communication device.
[0039] Please refer to Figure 2 , Figure 2 The following is a schematic diagram of an interactive process of a communication method provided by an embodiment of the present disclosure. Figure 2 As shown, the method includes:
[0040] In step S201, a sensing device senses a first speed of a user.
[0041] In the present disclosure, the sensing device may have the ability to measure the moving speed of the user terminal. Specifically, the sensing device of the present disclosure may use at least one sensing means such as radar, camera, or other suitable sensor technology to sense the first speed of the user.
[0042] In the present disclosure, the first speed can be understood as the current actual moving speed of the user terminal (such as a mobile phone, tablet computer, vehicle-mounted device, drone, helicopter, airplane, etc., which are not exhaustive here). The first speed can well reflect the current motion state of the user, thereby providing a solid foundation for dynamically determining the perception symbol configuration.
[0043] In step S202, the sensing device determines first information based on the first speed, where the first information is used to indicate a sensing symbol period.
[0044] In the present disclosure, after obtaining the first speed of the user, the perception device can determine the appropriate perception symbol period based on the first speed calculation, and determine it as the first information. Specifically, this can be done by finding the best perception symbol period (i.e., the first information) that matches the current speed (i.e., the first speed) through at least one method such as table lookup, deep learning model, signal propagation calculation, etc. The first information disclosed in the present disclosure can be used to indicate the perception symbol period determined by the above-mentioned perception device. The first information can exist in various forms, such as digital codes, frequency values, time intervals, etc., which may depend on the protocols and standards of the communication system, and are not limited here. In this way, the perception device can achieve a dynamic response to the user's moving speed and dynamically adjust the appropriate perception symbol period according to the user's speed. Then, it is achieved that the perception device can accurately perceive and determine the speed of the user terminal under different speeds. That is, the perception device dynamically adjusts the perception symbol period through the first speed, which can more accurately determine the movement trajectory of the user terminal, thereby improving the perception accuracy.
[0045] In step S203, the sensing device sends first information to the communication device.
[0046] In step S204, the communication device receives the first information sent by the sensing device.
[0047] In the present disclosure, the sensing device may send the determined first information to the communication device via a wired or wireless method. The communication device also receives the first information via a wired or wireless method. In this way, the sensing device and the communication device interact with each other to jointly determine the optimal sensing symbol period configuration to improve the sensing accuracy and reduce the system overhead.
[0048] In summary, the perception device can improve the accuracy of the perception symbol by dynamically adjusting the perception symbol period according to the actual mobile speed of the user device. At the same time, the interactive fine adjustment of the perception symbol period by the perception device and the communication device can reduce unnecessary resource consumption and reduce system overhead. In this way, the requirements of high accuracy and low system overhead can be balanced to a certain extent, and the requirements of perception symbol accuracy can be met within an acceptable overhead range, which can meet the objective needs in actual use.
[0049] As described above, the sensing device can dynamically determine the configuration period (i.e., the first information) of the sensing symbol according to the current actual moving speed (i.e., the first speed) of the user terminal. Hereinafter, how the sensing device dynamically obtains accurate first information will be specifically described. At this time, the method for the sensing device to obtain the first information includes:
[0050] The present disclosure can determine the first information by comparing the first speed with the current fuzzy interval, that is, determine whether the first speed can be identified through the current fuzzy interval, and adjust and determine the first information according to the first speed.
[0051] In one embodiment of the present disclosure, when the first speed is within the current ambiguity interval, a first period is determined; wherein the first period is smaller than a second period, and the second period is a current perception symbol configuration period.
[0052] In the present disclosure, the current fuzzy interval can be understood as an unrecognizable speed range, that is, within this range, the speed value may not be accurately classified into a certain exact value due to the accuracy limitation of at least one of the system, sensor, etc. Therefore, when the first speed falls into the current fuzzy interval, it means that the perception device cannot accurately identify the first speed of the user terminal. In this way, the range of the fuzzy area can be increased and the perception accuracy can be improved by shortening the perception symbol period (such as: encrypting the perception symbol density, adjusting the duration of the perception symbol, etc., not exhaustive). In other words, shortening the perception symbol period can be understood as increasing more perception opportunities per unit time, improving the ability to recognize the moving speed of the user terminal, and improving the perception accuracy.
[0053] Specifically, the current fuzzy interval can be calculated using the fuzzy speed.
[0054] The calculation of blur speed can satisfy the following formula:
[0055]
[0056] Where λ represents the wavelength of the signal; chirp represents the default perceptual symbol period; ΔK represents the speed variable.
[0057] Furthermore, the calculation of the current fuzzy interval can satisfy the following formula:
[0058] n*Blur speed ±3
[0059] Among them, n represents the multiple of speed; 3 represents the uncertainty range of speed, which is usually 3 and is adjusted accordingly according to different systems.
[0060] Thus, the current fuzzy interval can be calculated according to the above formula.
[0061] Exemplarily, the fuzzy speed interval of 2.5ms is n*22±3km / h, and the fuzzy speed probability is 24% in the interval of 0 to 100km / h; the fuzzy speed interval of 5ms is n*11±3km / h, and the fuzzy speed probability is 52% in the interval of 0 to 100km / h; the fuzzy speed interval of 10ms is n*5.5±3km / h, and the fuzzy speed probability is 97.5% in the interval of 0 to 100km / h.
[0062] In the present disclosure, the perception device can determine the first information by comparing the first speed with the current fuzzy interval. That is, determine whether the first speed is within the current fuzzy interval. When the first speed is within the current fuzzy interval, determine the first period. The first period is less than the second period (that is, the current perception configuration symbol period). In other words, when the first speed is within the current fuzzy interval, shorten the perception symbol period, that is, increase the frequency or density of the perception operation to improve the sensitivity or accuracy to speed changes. In this way, the perception device can flexibly and quickly dynamically adjust and determine the perception symbol period based on the comparison between the first speed and the current fuzzy interval to improve the accuracy of the perception symbol. This method can be applicable to scenarios where the speed change range is large or the speed change is uncertain.
[0063] In the present disclosure, specific methods for shortening the perception symbol period include but are not limited to at least one of the following: encrypting the perception symbol density, adjusting the duration of the perception symbol. All of the above can be adjusted by directly reusing existing technologies, or by selecting a method greater than the current symbol density and / or selecting a method less than the current duration, or by directly selecting a method less than the current perception symbol period to achieve the purpose of shortening the perception symbol period. The specific adjustment means are not limited here.
[0064] In the present disclosure, the specific degree of shortening the perception symbol period is not limited here, and it can be understood that as long as it is adjusted to be smaller than the current perception symbol period, it can also be adjusted smaller according to a preset value or a preset step or a preset algorithm. It can be flexibly adjusted according to system requirements or user needs.
[0065] For example, because the fuzzy speed interval of 5ms is n*11±3km / h; the fuzzy speed interval of 10ms is n*5.5±3km / h. If the user speed falls within the n*11±3km / h interval under the 5ms sensing symbol period, the sensing symbol period needs to be encrypted to 2.5ms, and the overhead is 20%; if the user speed falls within the n*22±3km / h interval under the 10ms sensing symbol period, the sensing symbol period needs to be encrypted to 1.25ms, and the overhead increases to 40%.
[0066] The present disclosure can also determine the first information by comparing the evaluation value with the threshold, that is, the optimal perceptual symbol period (i.e., the first information) can be identified and determined by comparing the evaluation value with the threshold. The first information determined in this way can fully consider the influence of multiple factors such as the system multi-dimensional evaluation standard and the dynamic threshold, and is more suitable for the actual situation during use.
[0067] In another embodiment of the present disclosure, when the first evaluation value is less than a first threshold, a first period is determined, and the first period is less than a second period; and / or, when the first evaluation value is greater than a second threshold, a third period is determined, and the third period is greater than the second period; wherein the first evaluation value is related to the first speed.
[0068] In the present disclosure, the first evaluation value can be understood as a more comprehensive consideration of dynamic adjustment, including at least one of the first speed, the change in the first speed, and the overall change of the first speed in the first time interval. Among them, the change in the first speed can be understood as the increase or decrease in the speed over a period of time, which can well reflect the speed change speed and trend. The overall change of the first speed in the first interval can be understood as a comprehensive evaluation within the first speed interval, including not only the speed / speed change, but also the stability of the speed change, periodicity, acceleration change and other aspects of the evaluation.
[0069] The specific first evaluation value can be dynamically adjusted and determined according to the changes in different adjustment factors. Among them, when the first evaluation value is the first speed, the instantaneous performance of the device at a certain moment can be intuitively reflected. This is particularly important for scenarios that require fast response and efficient transmission. When the first evaluation value is the change in the first speed, the dynamic change trend of the speed can be fully considered, which is very useful for predicting the future movement trajectory of the device. When the first evaluation value is the overall change of the first speed in the first time interval, the long-term performance of the device can be fully analyzed comprehensively, which is particularly important for scenarios that evaluate the average moving speed and long-term trends of the device.
[0070] In this embodiment, a possible implementation method is: the perception device can use the above-mentioned first evaluation value (any one or more) to compare with the first threshold. The first threshold can be understood as the minimum speed limit, and the value can be flexibly adjusted according to the specific system or user needs. When the first evaluation value is less than the first threshold, this means that the current performance fails to meet the minimum speed requirement of the system, the speed cannot be identified, and the perception accuracy requirement cannot be met. In this way, the second period can be determined by shortening the perception symbol period, etc., thereby meeting the perception accuracy requirement. The second period is less than the first period. For the specific method of shortening the perception symbol period, refer to the above and will not be repeated here.
[0071] In this embodiment, another possible implementation method is: the perception device can also use the above-mentioned first evaluation value (any one or more) to compare with the second threshold. The second threshold can be understood as the maximum speed limit, and the value can be flexibly adjusted according to the specific system or user requirements. When the first evaluation value is greater than the second threshold, this means that the current performance exceeds the maximum speed requirement achieved by the system, the speed cannot be identified, and the perception accuracy requirement cannot be met. In this way, the third period can be determined by extending the perception symbol period, etc., so as to meet the perception accuracy requirement. The third period is greater than the first period. For specific methods of extending the perception symbol period and shortening the perception symbol period, please refer to the above text for details, and no further details will be given here. In this way, the perception device can dynamically adjust and determine the perception symbol period based on the comparison of the evaluation value and the threshold. This method is suitable for scenarios where clear judgment results or automated decision-making are required, and can improve the accuracy of perception symbols.
[0072] Exemplarily, if the user speed is less than a certain value, the perception symbol period is reduced; if the user speed change is greater than a certain value, the perception period is modified, and a maximum period is used to prevent the estimated speed from falling into the ambiguous speed interval.
[0073] As described above, how the sensing device determines the first information is specifically described. Before determining the first information, the user's first speed needs to be sensed. The following specifically describes how the sensing device senses the user's first speed. At this time, the method for the sensing device to determine the speed includes:
[0074] Sending a sensing signal and receiving an echo signal of the sensing signal;
[0075] A first speed is determined based on the sensing signal and the echo signal.
[0076] In the present disclosure, the sensing device can send a sensing signal to the user terminal, and the sensing signal here can include but is not limited to at least one of the following: electromagnetic waves (such as radar signals), sound waves (such as ultrasound). The sensing device can receive an echo signal reflected from the user terminal. And by receiving a three-dimensional echo signal, it is compared with the sent sensing signal to determine the moving speed (i.e., the first speed) of the user terminal. This can accurately determine the moving speed (i.e., the first speed) of the user terminal by at least one method such as the time difference method and the Doppler effect. The specific determination method is not limited here. In this way, the sensing device does not need to be in direct contact with the user or the user terminal during the entire process, and can sense and determine the accurate moving speed of the user or the user terminal and respond in time.
[0077] In the present disclosure, the sensing device may sense the first position of the user while sensing the first speed of the user, and further determine the sending mode of the sensing symbol. In this case, the method for the sensing device to determine the sending mode of the sensing symbol includes:
[0078] Perceive the user's first position;
[0079] Based on the first position, configuring second information, where the second information is used to indicate a sensing symbol sending mode;
[0080] The second information includes: period information of at least one of sending, interval, and receiving in the perception symbol period.
[0081] In the present disclosure, the first location of a user may be understood as the current location of the user terminal.
[0082] In the present disclosure, the second information includes: period information of at least one of transmission (Transmission, T), interval (Guard Time, G), and reception (Reception, R) in the perception symbol period. Among them, the period information can be understood to include but is not limited to: the interval length and / or number of transmission (T), interval (G), and reception (R). Specifically, transmission (T) may refer to the transmission interval and the number of transmissions of the perception symbol. Interval (G) may refer to the interval time and the number of intervals between two perception symbol transmission intervals. Reception (R) may refer to the interval and the number of receptions in which the perception device receives the perception symbol echo.
[0083] In the present disclosure, the perception device can determine the transmission mode of the subsequent perception symbols according to the first position determined by perception, and determine it as the second information. Once the second information is determined, it will be used to guide the actual operation of the perception device. The perception device will send and receive perception symbols according to the sending, interval and receiving intervals and / or numbers specified in the second information. In this way, the perception device can obtain the user's position and speed information more efficiently, and provide more accurate and real-time data support for subsequent application scenarios.
[0084] Exemplarily, for users who are relatively close, the number of transmissions (T) of multiple transmissions and the number of receptions (R) of multiple receptions are configured, and accurate user speed is obtained by intensively sensing symbols for a period of time.
[0085] As described above, the sensing device can sense the first speed of the user. The present disclosure also provides a method for the sensing device to sense the first speed of the user. At this time, the method for the sensing device to sense the first speed includes:
[0086] Discontinuity perception first speed;
[0087] or,
[0088] Based on the received first request, a first speed is sensed; the first request is used to request to provide first information.
[0089] In one embodiment of the present disclosure, the sensing device may sense the first speed in a discontinuous manner. That is, the sensing device does not continuously monitor the speed change of the user, but senses in an intermittent or on-demand manner. This method may be applicable to scenarios where the real-time requirements are not very high and energy or computing resources are desired to be saved. Unnecessary computing and energy consumption may be reduced, and the life of the sensing device and the user terminal may be extended.
[0090] In another embodiment of the present disclosure, the perception device can also determine the perceived first speed based on the received first request. That is, the perception device can wait for a clear request (i.e., the first request) sent by an external system or a user terminal, which is used to request the provision of first information (here, the first speed information). This method is highly controllable and can achieve speed perception only when it is really needed, which can reduce unnecessary perception operations. At the same time, since the perception operation is triggered by an external request, it can also be integrated with other systems or applications, and no specific restrictions are made here.
[0091] As described above, it is specifically described how the sensing device senses the first speed and determines the first information.
[0092] The following describes a possible implementation method in which the sensing device sends the first information to the communication device:
[0093] In one embodiment of the present disclosure, the perception device may send the first information to the communication device through an interface, where the interface includes at least one of the following: an Xn interface and an Ng interface.
[0094] In the present disclosure, the perception device may have the ability to send the first information to the communication device through a specific interface. The interface of the present disclosure includes but is not limited to at least one of the following: Xn interface, Ng interface. In the embodiment of the present disclosure, the perception device can send the first information to the communication device through the Xn interface or the Ng interface, which means that the perception device is not limited to working alone, but can be integrated into a wide range of mobile communication networks and collaborate with other network nodes to complete complex perception and communication tasks.
[0095] Exemplarily, the sensing device can send the sensing symbol configuration and the sensing configuration time to the communication device through the Xn and Ng ports. The sensing symbol configuration can be understood as including the default configuration and the configuration to be adjusted. The sensing configuration effective time can be understood as the effective time of the configuration to be adjusted.
[0096] In another embodiment of the present disclosure, the perception device may send the first message to the communication device in a broadcasting manner, that is, send a broadcast message to the communication device, where the broadcast message carries the first information.
[0097] In the present disclosure, the sensing device may send the first information to the communication device by broadcasting, which can be understood as wireless interaction between the sensing device and the communication device. In this way, the efficiency of information dissemination can be improved, while increasing the flexibility of communication.
[0098] In this embodiment, the broadcast message also carries a broadcast radio network temporary identifier (Radio Network Temporary Identifier, RNTI); RNTI is used to indicate that the broadcast message comes from a sensing device. Specifically, RNTI, as an identifier of the broadcast message, can be used to clearly indicate which device the message comes from (in this case, the sensing device). In this way, the broadcast message can directly prompt all communication devices of the source of the broadcast message, and send information to multiple communication devices at one time, which can improve the efficiency of information dissemination and reduce the error rate of information transmission.
[0099] As described above, the sensing device senses the first speed and determines the first information to be sent to the notification device. The following will specifically describe that the sensing device can also receive the response of the communication device and make adjustments. Figure 3 , Figure 3 FIG. 1 is a schematic diagram of an interaction flow of another communication method provided in an embodiment of the present disclosure. Figure 3 As shown, the method includes:
[0100] In step S301, the communication device determines third information based on the first information, where the third information is used to indicate at least one of the following:
[0101] Confirming adjustment of the sensing symbol period information;
[0102] Resource avoidance indication information; used to indicate at least one of the time and resource of the sensing device to perform resource avoidance;
[0103] The prohibited occupation information is used to indicate at least one of the resources and time that the sensing device is prohibited from occupying.
[0104] In the present disclosure, the communication device may determine a response to the message (ie, the third message) according to the first information from the sensing device.
[0105] The third message of the present disclosure may be used to indicate at least one of the following:
[0106] Confirming the information of adjusting the sensing symbol period, that is, the communication device makes a definite response to the first message. In short, the communication device accepts the information about adjusting its sensing symbol period proposed by the sensing device. For example, the sensing station (that is, the sensing device of the present disclosure) is informed that the sensing symbol configuration update has been learned.
[0107] Resource avoidance indication information can be used to indicate the time and / or resources that the sensing device uses for resource avoidance. That is, this information will clearly indicate when and which resources (such as time slots, resources, etc.) the sensing device needs to avoid in order to ensure smooth communication. For example, based on the needs of the sensing site, the communication site determines whether to avoid resources within the effective time of the sensing configuration, or which parts of the resources to avoid.
[0108] The prohibited occupation information can be equivalent to indicating the resources and / or time that the sensing device is prohibited from occupying. That is, this information directly instructs the sensing device not to communicate or occupy the specified resources (such as specific frequencies, time periods, etc.). This is usually used to protect critical communication links or avoid serious interference with other devices in the network. For example: which resources of the communication site have the highest performance guarantee and cannot be interfered with, and are determined not to be occupied.
[0109] In this way, the communication device can fully consider the overhead of its own system, further fine-tune the perception symbol period according to the adjusted perception symbol period (i.e., the first message) sent by the perception device, and send the final interactively adjusted third message to the perception device. This can promote the collaboration between the communication device and the perception device and flexibly manage resources.
[0110] In step S302, the communication device sends third information to the sensing device.
[0111] In step S303, the sensing device receives third information from the communication device.
[0112] In the present disclosure, the communication device may send the third message to the perception device in a wireless or wired manner, and the perception device may also receive the third message in a wireless or wired manner.
[0113] In step S304, the sensing device configures the sensing symbol period based on the third information and makes it effective.
[0114] In the present disclosure, the perception device can configure the perception symbol period and make it effective according to the third message. In layman's terms, if the third information contains confirmation of the adjustment of the perception symbol period, the perception device will configure its perception operation according to the new period recommended by the communication device or agreed upon by both parties. If the third information contains instructions for resource avoidance, the perception device will identify the time periods and resource blocks that need to be avoided, and suspend or adjust its perception operations during these time periods. If the third information clearly indicates the resources and times that are prohibited from being occupied, the perception device will ensure that no communication or signal transmission is performed during these specified resources and times. In this way, the perception device and the communication device complete the entire fine interactive adjustment of the perception symbol configuration process, while meeting the requirements of perception symbol accuracy and low system overhead, and meeting the objective needs in actual use.
[0115] It is worth noting that if the perception device has greater authority or the user requires, the perception device can also dynamically adjust the perception symbol configuration and take effect. That is, the perception device can configure the perception symbol period to take effect without receiving a reply from the communication device. No specific restrictions are made here.
[0116] In an exemplary preferred embodiment, Figure 4 The flowchart of the complete communication method interaction provided by the embodiment of the present disclosure is as follows. Figure 4 As shown:
[0117] The perception site (i.e., the perception device of the present disclosure) can send a perception signal to the perception user (i.e., the user terminal of the present disclosure), and then receive the time (i.e., the echo signal of the present disclosure) and the position (i.e., the first position of the present disclosure) of the perception user's return. The perception site estimates the estimated speed (i.e., the first speed of the present disclosure), and then determines the perception symbol period (i.e., the first information of the present disclosure). And the perception symbol related configuration (i.e., the first information of the present disclosure) is sent to the communication site (i.e., the communication device of the present disclosure). The communication site replies to determine all or part of the configuration (i.e., the third message of the present disclosure). The perception site determines the perception symbol configuration based on the reply. The perception site can also notify the communication site by broadcasting (i.e., the broadcast message of the present disclosure).
