Description

Technical Field

[0001] This application belongs to the field of communication technology, and in particular relates to a method, apparatus, device, medium and product for transmitting sensing signals. Background Technology

[0002] Wireless communication systems will enable the realization of emerging technologies such as smart cities, intelligent industry, connected vehicles, and telemedicine. These emerging technologies share a common characteristic: they require both high-quality wireless communication capabilities and robust, high-precision sensing capabilities. Therefore, researching the integration of communication and sensing within the B5G / 6G (fifth-generation mobile communication / sixth-generation mobile communication) network framework is of great significance.

[0003] Current Integrated Sensing and Communications (ISAC) designs are primarily communication-centric. That is, they leverage existing Orthogonal Frequency Division Multiplexing (OFDM) communication waveforms and frame structures to achieve sensing, with sensing functionality being an add-on to communication. Their design prioritizes communication performance, focusing primarily on performance metrics such as channel capacity, spectral efficiency, and signal-to-interference-plus-noise ratio (SINR). The goal is to maximize sensing performance while ensuring communication capabilities. These communication-centric ISAC designs can achieve sensing functionality without sacrificing communication performance, thereby obtaining higher data transmission rates.

[0004] ISAC, which implements sensing based on OFDM communication waveforms and frame structures, requires a cyclic prefix (CP) length sufficient to cover the sensing path delay to meet coverage requirements. However, when a base station or terminal needs to sense both near-range targets (lower delay) and far-range targets (higher delay), the multipath delay spread of the sensing signal may exceed the capabilities of the Network Control Protocol (NCP). The NCP will then be unable to resolve inter-symbol interference (ISC) issues, making it difficult to guarantee sensing performance. For example, with a subcarrier spacing of 15kHz, when the sensing distance is too far, the NCP will be unable to resolve ISC issues, and the sensing coverage distance will be limited as the subcarrier spacing increases. Summary of the Invention

[0005] This application provides a method, apparatus, device, medium, and product for transmitting sensing signals. A first device concatenates a cyclic prefix signal of a target cyclic prefix length with a first sensing signal to obtain a second sensing signal, and sends the second sensing signal to the second device using multiple OFDM symbols. The second device determines the cyclic prefix signal that needs to be split based on the target cyclic prefix length to obtain an effective sensing signal. That is, by adjusting the length of the cyclic prefix signal, the device can sense distant targets, solving the problem of possible interference between symbols and improving sensing performance. Furthermore, by setting the target cyclic prefix length and adjusting the length of the cyclic prefix signal of the sensing signal, sending the sensing signal to the second device using multiple OFDM symbols can also effectively improve the sensing coverage distance.

[0064] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0065] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0066] Wireless communication systems will enable the realization of emerging technologies such as smart cities, intelligent industry, connected vehicles, and telemedicine. These emerging technologies share a common characteristic: they require both high-quality wireless communication capabilities and robust, high-precision sensing capabilities. Therefore, researching the integration of communication and sensing within the B5G / 6G (fifth-generation mobile communication / sixth-generation mobile communication) network framework is of great significance.

[0067] Current Integrated Sensing and Communications (ISAC) designs are primarily communication-centric. That is, they leverage existing Orthogonal Frequency Division Multiplexing (OFDM) communication waveforms and frame structures to achieve sensing, with sensing functionality being an add-on to communication. Their design prioritizes communication performance, focusing primarily on performance metrics such as channel capacity, spectral efficiency, and signal-to-interference-plus-noise ratio (SINR). The goal is to maximize sensing performance while ensuring communication capabilities. These communication-centric ISAC designs can achieve sensing functionality without sacrificing communication performance, thereby obtaining higher data transmission rates.

[0068] ISAC, which implements sensing based on OFDM communication waveforms and frame structures, requires a cyclic prefix (CP) length sufficient to cover the sensing path delay to meet coverage requirements. However, when a base station or terminal needs to sense both near-range targets (lower delay) and far-range targets (higher delay), the multipath delay spread of the sensing signal may exceed the capabilities of the Network Control Protocol (NCP). The NCP will then be unable to resolve inter-symbol interference (ISC) issues, making it difficult to guarantee sensing performance. For example, with a subcarrier spacing of 15kHz, when the sensing distance is too far, the NCP will be unable to resolve ISC issues, and the sensing coverage distance will be limited as the subcarrier spacing increases.

[0069] To address the problems of existing technologies, embodiments of this application provide a method, apparatus, device, medium, and product for transmitting sensing signals. The sensing signal transmission method provided in this application involves a first device concatenating a cyclic prefix signal of a target cyclic prefix length with a first sensing signal to obtain a second sensing signal. This second sensing signal is then transmitted to a second device using multiple OFDM symbols. The second device determines the cyclic prefix signal to be split based on the target cyclic prefix length, thus obtaining an effective sensing signal. Specifically, by adjusting the length of the cyclic prefix signal, the device can sense distant targets, resolving potential interference between symbols and improving sensing performance. Furthermore, by setting the target cyclic prefix length and adjusting the length of the cyclic prefix signal of the sensing signal, transmitting the sensing signal to the second device using multiple OFDM symbols can also effectively increase the sensing coverage distance. The method for transmitting sensing signals provided in this application can be applied to the fields of smart low-altitude (such as path planning for logistics drones), smart transportation (such as in the Internet of Vehicles scenario, where integrated sensing can realize the identification and perception of the road itself and the road environment, the identification of the vehicle's position, speed and direction of movement, and the realization of communication between vehicles and between vehicles and infrastructure), and smart living (such as controlling smart homes through gesture recognition and action recognition).

[0070] It should be noted that in 5G systems, the subcarrier spacing (SCS) and μ correspond (SCS = 2). μ *15kHz), μ can take values ​​of 0, 1, 2, 3, and 4, meaning the SCS can be 15kHz, 30kHz, 60kHz, 120kHz, or 240kHz. According to OFDM principles, the OFDM symbol length and SCS are inversely proportional; the larger the SCS, the smaller the OFDM symbol length and the smaller the time slot length. If the subframe length is fixed (e.g., 1ms), the larger the SCS, the larger the number of time slots contained in a subframe. For example, when the SCS is 15kHz (μ = 0), the number of time slots contained in a subframe is 1. As the SCS increases to 30kHz, 60kHz, 120kHz, 240kHz, and 480kHz, the number of time slots contained in a subframe also increases to 2, 4, 8, 16, and 32, respectively.

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

[0072] In 5G NR (New Radio), the signal length of FFT (Fast Fourier Transform) can be 4096 time-domain sampling points, with a maximum SCS of 480kHz. The basic time unit Tc = 1 / (480000 x 4096) is the basic time unit corresponding to the signal. An OFDM symbol 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 length of the half-frame signal is 1 / (15000x 4096)*30720=0.0005s, or 0.5ms.

[0073] NR supports a SCS (Segment Cross Section) of at least 15kHz, similar to LTE. On one hand, a larger SCS results in a smaller OFDM symbol length, making it more suitable for latency-sensitive services such as URLLC (Ultra-Reliable Low-Latency Communication). On the other hand, a larger SCS provides better suppression of frequency offset (Doppler effect) and ICI (Inter-Carrier Interference). Conversely, a larger SCS leads to lower spectrum utilization, and a smaller CP (Channel Cross Section) length, making it less effective at overcoming multipath interference.

[0074] The method for transmitting sensing signals provided in the embodiments of this application will be described below. Figure 1 A schematic flowchart of a method for transmitting sensing signals according to an embodiment of this application is shown.

[0075] like Figure 1 As shown, the method for transmitting sensing signals provided in this application includes the following steps.

[0076] S110, The first device acquires the first sensing signal and the target cyclic prefix length.

[0077] Here, the first device is the transmitter of the sensing signal. The target cyclic prefix length can be pre-set, and is not less than the regular cyclic prefix (CP) length.

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

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

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

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

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

[0083] S130, the first device splices the cyclic prefix signal and the first sensing signal to obtain the second sensing signal, which occupies multiple OFDM symbols.

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

[0085] In some embodiments, the splicing method of the cyclic prefix signal and the first sensing signal is not limited here.

[0086] S140, the first device sends a second sensing signal to the second device.

[0087] In some embodiments, after the first device concatenates the cyclic prefix signal and the first sensing signal, it maps the resulting second sensing signal onto the corresponding subcarrier to generate the final OFDM symbol sequence. At this time, the OFDM symbol sequence may also include the mapping result of the communication signal on the corresponding subcarrier, while the communication signal remains unchanged. This OFDM symbol sequence is processed by the physical layer, and with the addition of necessary synchronization information and control signals, the entire signal sequence is transmitted. The physical layer processing can be implemented using existing technologies; for the sake of applicability to different services, it will not be elaborated upon here.

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

[0089] Here, the target loop prefix length is pre-set and is the same as the target loop prefix length in the first device.

[0090] S160, the second device extracts the cyclic prefix signal of the target cyclic prefix length from the second sensing signal to obtain the first sensing signal.

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

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

[0093] In this way, the first device concatenates the cyclic prefix signal of the target cyclic prefix length with the first sensing signal to obtain the second sensing signal, and sends it to the second device using multiple OFDM symbols. The second device then determines the cyclic prefix signal that needs to be split based on the target cyclic prefix length to obtain an effective sensing signal. That is, by adjusting the length of the cyclic prefix signal, the device can sense distant targets, solving the problem of possible interference between symbols and improving sensing performance. Furthermore, by setting the target cyclic prefix length and adjusting the length of the cyclic prefix signal of the sensing signal, sending the sensing signal to the second device using multiple OFDM symbols can also effectively improve the sensing 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 acquires a first sensing signal, sensing target information, and preset relationship information between preset sensing target information and preset cyclic prefix length;

[0096] S112. The first device determines the target loop prefix length corresponding to the perceived target information according to the preset relationship information. The preset perceived target information includes the perceived target information, and the preset loop prefix length includes the target loop prefix length.

[0097] Specifically, S150 may include:

[0098] S151. When the second device receives the second sensing signal sent by the first device, it acquires sensing target information and preset relationship information between the preset sensing target information and the preset cyclic prefix length.

[0099] S152. The second device determines the target loop prefix length corresponding to the perceived target information according to the preset relationship information. The preset perceived target information includes the perceived target information, and the preset loop prefix length includes the target loop prefix length.

[0100] Here, in S111 above, the preset relationship information between the preset sensing target information and the preset cyclic prefix length is pre-defined, that is, a series of preset CP length configuration relationship information is defined. For different scenarios and sensing targets, the most suitable CP length is selected for configuration and sent to the first and second devices via network configuration or control signaling. The first device is the transmitter of the sensing signal, and the second device is the receiver of the sensing signal. Through the preset relationship information between the preset sensing target information and the preset cyclic prefix length, the first device can generate a second sensing signal as needed. Specifically, in S112 above, the target cyclic prefix length is sufficient to cover the length of the sensing target corresponding to the sensing target information. This ensures that the CP length is sufficient to cover the sensing path delay and reduces multipath interference.

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

[0102] Furthermore, in S151 above, the preset relationship information between the preset sensing target information and the preset loop prefix length is pre-set and is the same as the preset relationship information between the preset sensing target information and the preset loop prefix length in the first device. In S152 above, the second device determines the corresponding target loop prefix length for the sensing target information. It can be understood that this target loop prefix length is the same as the target loop 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 perceived target information. After splicing the adjusted cyclic prefix signal with the first perceived signal, it is sent to the second device. The second device can then determine the cyclic prefix signal that needs to be split according to the perceived target information to obtain an effective perceived signal. That is, by adjusting the length of the cyclic prefix signal, the device can perceive both near-range and far-range targets, solving the problem of possible interference between symbols and improving the perception performance. Moreover, by adjusting the length of the cyclic prefix signal according to the perceived 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 the target cyclic prefix length preceding the first sensing signal, and the above-mentioned S130 may specifically include:

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

[0106] In this way, by stitching the target matching CP before the first sensing signal, even if multipath propagation exists, 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, prior to S140 above, the method may further include:

[0108] S131, The first device acquires the first length of the second sensing signal;

[0109] S132. The first device determines the second length of the target OFDM symbol occupied by the second sensing signal based on the first length. The target OFDM symbol includes multiple OFDM symbols, and the second length is not less than the first length.

[0110] Specifically, S140 may include:

[0111] S141. The first device uses the subcarrier corresponding to the target OFDM symbol of the second length to send a second sensing signal to the second device.

[0112] Here, the second length is the length of multiple OFDM symbols, and 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 sensing signal is designed to span multiple consecutive OFDM symbols; that is, within a sensing period, the signal is not transmitted within only one OFDM symbol, but extends to two or more adjacent OFDM symbols. During signal scheduling, the first device appropriately allocates the sensing signal to the subcarriers corresponding to the target OFDM symbol of the second length and transmits it to the second device.

[0114] By using one sensing signal to occupy multiple OFDM symbols, the CP length of the sensing signal is significantly increased. Even with multipath propagation, it can ensure that all path delays arrive within the CP time, avoiding inter-symbol interference and effectively improving sensing performance.

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

[0116] When the second length is greater than the first length, the first device splices the cyclic prefix signal and the first sensing signal, and splices the target sensing signal of the third length after the first sensing signal to obtain the second sensing signal. The third length is the difference between the second length and the first length.

[0117] Specifically, S160 mentioned above may include:

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

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

[0120] In some embodiments, the difference in length between the second sensing signal and the target OFDM symbol can be compensated using the target sensing signal.

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

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

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

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

[0125] Understandably, the signal has changed, and the content structure of each OFDM symbol has changed.

[0126] In some embodiments, the CP4 portion provides additional flexibility, allowing for idle periods or random filling, further extending the CP length to accommodate sensing needs at different distances.

[0127] In this way, due to the significant increase in the CP length of the sensing symbol, even in the presence of multipath propagation, it can be ensured that all path delays arrive within the CP time, avoiding inter-symbol interference and effectively reducing the degradation of sensing performance caused by multipath. The random padding of the cyclic prefix signal and the target sensing signal helps to reduce the bit error rate at the receiver and improve sensing 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 splices the cyclic prefix signal and the first sensing signal to obtain the fourth sensing signal;

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

[0131] Specifically, S160 mentioned above may include:

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

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

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

[0135] In this way, transmitting the sensed signal after fast Fourier transform improves data transmission efficiency and ensures effective signal transmission.

[0136] In the embodiments provided in this application, while keeping the communication signal and sensing signal SCS unchanged, one sensing symbol occupies multiple (two or more) OFDM symbols. The sensing signal consists of three parts, and the OFDM symbol signal splicing method is used. This effectively improves the sensing coverage distance and effectively covers sensing path delay while maintaining compatibility with 5G terminal communication. Through the designed signal splicing and flexible CP configuration, not only is the multipath interference problem effectively overcome, but the sensing distance and accuracy are also greatly improved, while maintaining compatibility with existing 5G systems. This lays a solid foundation for future 6G networks and integrated sensing applications.

[0137] In the embodiments provided in this application, while keeping the communication signal and sensing signal SCS unchanged, one sensing symbol occupies two or more OFDM symbols spliced ​​together, thus solving the problem of limited sensing distance. The main objective is to maximize the overall network sensing performance while satisfying different sensing service distributions.

[0138] In the embodiments provided in this application, OFDM symbol splicing is used. This satisfies the multi-target sensing requirements in integrated communication and sensing, and solves the problem that when a base station or terminal needs to sense both near-range targets (lower latency) and far-range targets (higher latency), the multipath delay spread of the sensing signal may exceed the NCP capability. It can maintain good communication capabilities while being compatible with existing NR structures, improving sensing coverage distance perception and achieving better sensing performance.
