Description

Technical Field

[0001] The present application belongs to the field of communication technology, and in particular, relates to a method, device, equipment, medium and product for transmitting a perception signal. Background Art

[0002] Wireless communication systems will make it possible to realize emerging technologies such as smart cities, smart industries, Internet of Vehicles, and telemedicine. These emerging technologies have one thing in common, which is that they require both high-quality wireless communication capabilities and robust and high-precision perception capabilities. Therefore, it is of great significance to study the integration of communication and perception under the B5G / 6G (fifth generation mobile communication / sixth generation mobile communication) network framework.

[0003] The current Integrated Sensing and Communications (ISAC) is mainly centered on communication. That is, perception is achieved based on the existing Orthogonal Frequency Division Multiplexing (OFDM) communication waveform and frame structure, and the perception function is an additional part of communication. Its design gives priority to communication performance, mainly based on communication performance indicators such as channel capacity, spectrum efficiency, Signal to Interference plus Noise Ratio (SINR), etc. Maximize perception performance while ensuring communication performance. These communication-centric ISAC designs can achieve perception functions without sacrificing communication performance, thereby obtaining higher data transmission rates.

[0004] ISAC, which implements perception based on OFDM communication waveform and frame structure, needs to have a cyclic prefix (CP) length sufficient to cover the perception path delay in order to meet the requirements of the perception coverage range. However, when the base station or terminal needs to perceive both close-range targets (with shorter delay) and long-range targets (with longer delay), the multipath delay extension of the perception signal may exceed the capability of the Network Control Protocol (NCP). NCP will not be able to solve the problem of inter-symbol interference, and the perception performance will be difficult to guarantee. Taking the subcarrier spacing of 15kHz as an example, when the perception distance is too far, NCP will not be able to solve the problem of inter-symbol interference. As the subcarrier spacing increases, the perception coverage distance will be limited. Summary of the invention

[0064] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0065] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0066] Wireless communication systems will make it possible to realize emerging technologies such as smart cities, smart industries, Internet of Vehicles, and telemedicine. These emerging technologies have one thing in common, which is that they require both high-quality wireless communication capabilities and robust and high-precision perception capabilities. Therefore, it is of great significance to study the integration of communication and perception under the B5G / 6G (fifth generation mobile communication / sixth generation mobile communication) network framework.

[0067] The current Integrated Sensing and Communications (ISAC) is mainly centered on communication. That is, perception is achieved based on the existing Orthogonal Frequency Division Multiplexing (OFDM) communication waveform and frame structure, and the perception function is an additional part of communication. Its design gives priority to communication performance, mainly based on communication performance indicators such as channel capacity, spectrum efficiency, Signal to Interference plus Noise Ratio (SINR), etc. Maximize perception performance while ensuring communication performance. These communication-centric ISAC designs can achieve perception functions without sacrificing communication performance, thereby obtaining higher data transmission rates.

[0068] ISAC, which implements perception based on OFDM communication waveform and frame structure, needs to have a cyclic prefix (CP) length sufficient to cover the perception path delay in order to meet the requirements of the perception coverage range. However, when the base station or terminal needs to perceive both close-range targets (with shorter delay) and long-range targets (with longer delay), the multipath delay extension of the perception signal may exceed the capability of the Network Control Protocol (NCP). NCP will not be able to solve the problem of inter-symbol interference, and the perception performance will be difficult to guarantee. Taking the subcarrier spacing of 15kHz as an example, when the perception distance is too far, NCP will not be able to solve the problem of inter-symbol interference. As the subcarrier spacing increases, the perception coverage distance will be limited.

[0069] In order to solve the problems of the prior art, the embodiments of the present application provide a method, device, equipment, medium and product for transmitting a perception signal. The embodiment of the present application provides a method for transmitting a perception signal, wherein the first device splices the cyclic prefix signal of the target cyclic prefix length with the first perception signal to obtain a second perception signal, and occupies multiple OFDM symbols to send it to the second device, so that the second device can determine the cyclic prefix signal that needs to be split according to the target cyclic prefix length to obtain an effective perception signal, that is, by adjusting the length of the cyclic prefix signal, the device can perceive a distant target, solve the possible interference problem between symbols, and improve the perception performance, and by setting the target cyclic prefix length, the length of the cyclic prefix signal of the perception signal is adjusted, and multiple OFDM symbols are occupied to send the perception signal to the second device, which can also effectively improve the perception coverage distance. The method for transmitting perception signals provided in the embodiments of the present application can be applied to the field of smart low-altitude (such as path planning for logistics drones), the field of smart transportation (such as in the Internet of Vehicles scenario, the integration of synaesthesia can realize the recognition and perception of the road itself and the road environment, the position, speed and direction of movement of the vehicle, and the communication between vehicles and between vehicles and infrastructure) and the field of smart life (such as controlling smart homes through gesture recognition and action recognition).

[0070] It should be noted that in the 5G system, the subcarrier spacing (SCS) corresponds to μ (SCS = 2 μ *15kHz), μ can take values ​​of 0, 1, 2, 3, 4, that is, SCS can be 15kHz, 30kHz, 60kHz, 120kHz or 240kHz. According to the OFDM principle, the OFDM symbol length is inversely proportional to the SCS size. The larger the SCS, the smaller the OFDM symbol length and the smaller the time slot length. If the subframe length is fixed (such as 1ms), the larger the SCS, the larger the number of time slots contained in a subframe. For example, when SCS is 15kHz (μ=0), the number of time slots contained in a subframe is 1, and SCS increases exponentially to 30kHz, 60kHz, 120kHz, 240kHz, 480kHz, and the number of time slots contained in a subframe also increases exponentially to 2, 4, 8, 16, 32.

[0071] Here, time slot refers to a fixed time interval for data transmission and reception within a specific time period. The basic principle of OFDM is to encode high-speed information data and distribute it to multiple mutually orthogonal subcarriers for parallel transmission. When sending perception signals, the perception data can be converted into a digital signal stream, which is then decomposed into multiple low-rate data streams through serial-to-parallel conversion and modulated onto each subcarrier. In this way, the perception signal is effectively encapsulated in the OFDM symbol and transmitted to the receiving end through the wireless channel.

[0072] In 5G NR (New Radio), the signal length of FFT (Fast Fourier Transform) can be 4096 time domain sampling points, the maximum SCS is 480kHz, and the basic time unit Tc = 1 / (480000x 4096), which is the basic time unit corresponding to the signal. OFDM symbols can contain 4096 sampling points. If a conventional CP is used, the CP contains 288 sampling points. In each half frame, the CP of the first signal is slightly longer. Specifically, when the SCS is 15kHz, 30kHz, 60kHz, and 120kHz, the CP of the first signal is 32 (320-288=32), 64, 128, and 256 more sampling points, respectively. Taking SCS=15kHz as an example, one half frame contains 7 symbols, the number of sampling points is (288+4096)*7+32=30720, and the half frame signal length is 1 / (15000x 4096)*30720=0.0005s, that is, 0.5ms.

[0073] The SCS supported by NR is no less than 15kHz of LTE. On the one hand, the larger the SCS, the smaller the OFDM symbol length, and the more suitable it is for delay-sensitive services, such as URLLC (Ultra Reliable Low Latency Communication) scenarios. On the other hand, the larger the SCS, the better the suppression of frequency deviation (Doppler effect) and ICI (Inter Carrier Interference). On the other hand, the larger the SCS, the lower the spectrum utilization, and at the same time, the smaller the CP length, the less conducive it is to overcome multipath interference.

[0074] The following first introduces the method for transmitting the perception signal provided in the embodiment of the present application. Figure 1 A schematic flow chart of a method for transmitting a perception signal provided in an embodiment of the present application is shown.

[0075] like Figure 1 As shown, the method for transmitting a perception signal provided in an embodiment of the present application includes the following steps.

[0076] S110. The first device obtains a first perception signal and a target cyclic prefix length.

[0077] Here, the first device is a transmitter of the perception signal. The target cyclic prefix length may be set in advance and is not less than a normal cyclic prefix (CP) length.

[0078] In some embodiments, the first perception signal is a valid perception signal. It can be understood that a signal composed of a signal of a regular cyclic prefix (CP) length and the valid perception signal occupies one OFDM symbol.

[0079] In some embodiments, the target cyclic prefix length does not exceed a length of the first perceptual signal.

[0080] S120. The first device extracts a cyclic prefix signal of a target cyclic prefix length from the first perception signal.

[0081] In some embodiments, the first device may randomly extract a cyclic prefix signal of a target cyclic prefix length from the first perception signal.

[0082] In some embodiments, the first device may also intercept the cyclic prefix signal of the target cyclic prefix length from the first perception signal according to a preset rule. For example, the preset rule may be to intercept the cyclic prefix signal of the target cyclic prefix length from the tail of the first perception signal.

[0083] S130. The first device concatenates the cyclic prefix signal and the first perception signal to obtain a second perception signal, where the second perception signal occupies multiple OFDM symbols.

[0084] Here, the length of the effective perception signal in the second perception signal remains unchanged, and the length of the cyclic prefix signal is increased.

[0085] In some embodiments, the concatenation method of the cyclic prefix signal and the first perception signal is not limited herein.

[0086] S140. The first device sends a second perception signal to the second device.

[0087] In some embodiments, after the first device completes the splicing of the cyclic prefix signal and the first perception signal, it maps the obtained second perception signal to the corresponding subcarrier to generate a final OFDM symbol sequence. At this time, the OFDM symbol sequence can also include the mapping result of the communication signal on the corresponding subcarrier, and the communication signal remains unchanged. The OFDM symbol sequence is processed by the physical layer, and the necessary synchronization information and control signals are added, and the entire signal sequence will be sent out. The physical layer processing process can be implemented using the methods in the prior art. In order to be applicable to different services, it will not be described in detail here.

[0088] S150: When receiving the second perception signal sent by the first device, the second device obtains a target cyclic prefix length.

[0089] Here, the target cyclic prefix length is set in advance and is the same as the target cyclic prefix length in the first device.

[0090] S160. The second device separates a cyclic prefix signal of a target cyclic prefix length from the second perception signal to obtain a first perception signal.

[0091] In some embodiments, the second device needs to identify and correctly align perception signal segments dispersed in multiple OFDM symbols, and separate a cyclic prefix signal of a target cyclic prefix length from the second perception signal to obtain a first perception signal.

[0092] In some embodiments, the first perception signal may include target distance and speed, etc., so that the user can analyze the first perception signal to obtain different features and use tools to achieve accurate perception of multiple targets.

[0093] In this way, the first device splices the cyclic prefix signal of the target cyclic prefix length with the first perception signal to obtain a second perception signal, and occupies multiple OFDM symbols to send it to the second device, so that the second device can determine the cyclic prefix signal that needs to be split according to the target cyclic prefix length to obtain a valid perception signal. That is, by adjusting the length of the cyclic prefix signal, the device can perceive distant targets, solves the possible interference problem between symbols, and improves the perception performance. By setting the target cyclic prefix length, the length of the cyclic prefix signal of the perception signal is adjusted, and multiple OFDM symbols are occupied to send the perception signal to the second device, which can also effectively improve the perception coverage distance.

[0094] Based on this, in some embodiments, such as Figure 2 As shown, the above S110 may specifically include:

[0095] S111. The first device obtains a first perception signal, perception target information, and preset relationship information between preset perception target information and preset cyclic prefix length;

[0096] S112. The first device determines, according to preset relationship information, a target cyclic prefix length corresponding to the sensing target information, where the preset sensing target information includes the sensing target information, and the preset cyclic prefix length includes the target cyclic prefix length;

[0097] The above S150 may specifically include:

[0098] S151. When receiving a second perception signal sent by the first device, the second device obtains perception target information and preset relationship information between preset perception target information and preset cyclic prefix length;

[0099] S152. The second device determines, according to preset relationship information, a target cyclic prefix length corresponding to the perception target information, where the preset perception target information includes the perception target information, and the preset cyclic prefix length includes the target cyclic prefix length.

[0100] Here, in the above S111, the preset relationship information between the preset perception target information and the preset cyclic prefix length is set in advance, that is, a series of CP length configuration relationship information is preset, and the most appropriate CP length is selected for configuration for different scenarios and perception targets, and is sent to the first device and the second device through network configuration or control signaling. Among them, the first device is the transmitter of the perception signal, and the second device is the receiver of the perception signal. Through the preset relationship information between the preset perception target information and the preset cyclic prefix length, the first device can generate a second perception signal according to demand. Specifically, in the above S112, the target cyclic prefix length is a length sufficient to cover the perception target corresponding to the perception target information. Ensure that the CP length is sufficient to cover the perception path delay and reduce multipath interference.

[0101] In some embodiments, the first sensing signal is a valid sensing signal, and the sensing target information is information of a target that needs to be sensed.

[0102] In addition, in the above S151, the preset relationship information between the preset perception target information and the preset cyclic prefix length is set in advance, and is the same as the preset relationship information between the preset perception target information and the preset cyclic prefix length in the first device. In the above S152, the second device determines the corresponding target cyclic prefix length for the perception target information. It can be understood that the target cyclic prefix length is the same as the target cyclic prefix length determined by the first device.

[0103] In this way, the first device can adjust the length of the cyclic prefix signal according to the perception target information, splice the cyclic prefix signal adjusted according to the perception target information with the first perception signal, and send it to the second device, so that the second device can determine the cyclic prefix signal that needs to be split according to the perception target information to obtain a valid perception signal. That is, by adjusting the length of the cyclic prefix signal, the device can perceive both close and long-distance targets, solve the possible interference problem between symbols, and improve the perception performance. Moreover, by adjusting the length of the cyclic prefix signal according to the perception target information, the cyclic prefix signal can be adjusted more accurately to meet the effective coverage of the perception path delay in all cases and effectively improve the perception coverage distance.

[0104] Based on this, in some embodiments, the cyclic prefix signal is a signal of a target cyclic prefix length before the first perception signal, and the above S130 may specifically include:

[0105] The first device splices a cyclic prefix signal before the first perception signal to obtain a second perception signal.

[0106] In this way, by splicing the CP that matches the perception target before the first perception signal, even if there is multipath propagation, it can ensure that all path delays arrive within the CP time, avoid inter-symbol interference, and effectively reduce the perception performance degradation caused by multipath.

[0107] Based on this, in some embodiments, such as Figure 3 As shown, before the above S140, the method may further include:

[0108] S131. The first device obtains a first length of a second perception signal;

[0109] S132. The first device determines, according to the first length, a second length of a target OFDM symbol occupied by the second perception signal, where the target OFDM symbol includes a plurality of OFDM symbols, and the second length is not less than the first length;

[0110] The above S140 may specifically include:

[0111] S141. The first device sends a second perception signal to the second device by using a subcarrier corresponding to a target OFDM symbol of a second length.

[0112] Here, the second length is the length of multiple OFDM symbols, which is an integer multiple of the OFDM symbol length. The second length is greater than or equal to the first length.

[0113] In some embodiments, the second perception signal is designed to span multiple consecutive OFDM symbols, that is, within a perception period, the signal is not sent only within one OFDM symbol, but is extended to two or more adjacent OFDM symbols. When scheduling the signal, the first device reasonably allocates the perception signal to the subcarriers corresponding to the target OFDM symbol of the second length and sends it to the second device.

[0114] In this way, one perception signal occupies multiple OFDM symbols, which significantly increases the CP length of the perception signal. Even if there is multipath propagation, it can ensure that all path delays arrive within the CP time, avoid inter-symbol interference, and effectively improve the perception performance.

[0115] Based on this, in some embodiments, the above S130 may specifically include:

[0116] When the second length is greater than the first length, the first device concatenates the cyclic prefix signal and the first perception signal, and concatenates a target perception signal of a third length after the first perception signal to obtain a second perception signal, where the third length is a difference between the second length and the first length;

[0117] The above S160 may specifically include:

[0118] The second device acquires a first length of the second perception signal;

[0119] When the second length is greater than the first length, the second device splits the cyclic prefix signal of the target cyclic prefix length and the target perception signal of the third length from the second perception signal to obtain the first perception signal, where the target perception signal is the signal after the first perception signal, and the third length is the difference between the second length and the first length.

[0120] In some embodiments, the difference between the length of the second perception signal and the length of the target OFDM symbol may be supplemented by the target perception signal.

[0121] As an example, Figure 4 As shown, taking the second perception signal occupying two OFDM symbols as an example, the duration of the original two ODFM symbols is composed of cp1, cp2 and two parts of effective signals. While keeping the communication signal and the perception signal SCS unchanged, it is changed to one perception signal occupying two OFDM symbols, where the perception signal is composed of three parts:

[0122] (1) The effective sensing signal part, for example, may have a length of 2048K, where K = 64 × 2 μ , μ=0, 1, 2, 3, 4, 5, 6, corresponding to SCS=15kHz, 30kHz, 60kHz, 120kHz, 240kHz, 480kHz, 960kHz respectively;

[0123] (2) The CP3 part is the cyclic prefix signal, which is generated by intercepting the effective sensing signal part.

[0124] (3) CP4 part: This part can be empty (i.e. no information is sent at this time) or filled randomly. CP4 is placed after the perception signal part.

[0125] It is understandable that the signal has changed and the content structure of each OFDM symbol has changed.

[0126] In some embodiments, the CP4 portion provides additional flexibility and can be an idle period or randomly filled, further extending the CP length to accommodate sensing requirements at different distances.

[0127] In this way, since the CP length of the perception symbol is significantly increased, even in the presence of multipath propagation, it can ensure that all path delays arrive within the CP time, avoiding inter-symbol interference and effectively reducing the perception performance degradation caused by multipath. The random filling part of the cyclic prefix signal and the target perception signal helps to reduce the bit error rate at the receiving end and improve the perception accuracy.

[0128] Based on this, in some embodiments, such as Figure 5 As shown, the above S130 may specifically include:

[0129] S210. The first device concatenates the cyclic prefix signal and the first perception signal to obtain a fourth perception signal.

[0130] S220. The first device performs fast Fourier transform processing on the fourth perception signal to obtain a second perception signal.

[0131] The above S160 may specifically include:

[0132] S161. The second device performs inverse fast Fourier transform processing on the second perception signal to obtain a fourth perception signal.

[0133] S162. The second device separates a cyclic prefix signal of a target cyclic prefix length from the fourth perception signal to obtain a first perception signal.

[0134] Here, the second perception signal is a time domain signal. After receiving the signal, the second device first performs an inverse fast Fourier transform to restore the original fourth perception signal. The received fourth perception signal is de-CP and decoded to obtain the first perception signal.

[0135] In this way, the perception signal is transmitted after being processed by fast Fourier transform, which improves the data transmission efficiency and ensures the effective transmission of the signal.

[0136] In the embodiment provided in the present application, while keeping the communication signal and the perception signal SCS unchanged, a perception symbol occupies multiple (two or more) OFDM symbols, where the perception signal consists of three parts, and the OFDM symbol signal splicing occupies the mode, while being compatible with 5G terminal communication, it can effectively improve the perception coverage distance and effectively cover the perception path delay. Through the designed signal splicing and flexible CP configuration, not only the multipath interference problem is effectively overcome, but also the perception distance and accuracy are greatly improved, while maintaining compatibility with the existing 5G system, laying a solid foundation for the future 6G network and synaesthesia integrated application.

[0137] In the embodiment provided in the present application, while keeping the communication signal and the perception signal SCS unchanged, one perception symbol occupies two or more OFDM symbols to solve the problem of limited perception distance. The main goal is to maximize the overall network perception performance of the network while meeting the distribution of different perception services.

[0138] In the embodiment provided in this application, OFDM symbol splicing and occupation is adopted. It meets the needs of multi-target perception in communication perception integration, and solves the problem that when the base station or terminal needs to perceive both close-range targets (lower delay) and long-range targets (larger delay), the multipath delay extension of the perception signal may exceed the NCP capability. It can be compatible with the existing NR structure while maintaining good communication capabilities, improve the perception coverage distance, and achieve better perception performance.
