Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to a perception method, a signal configuration method, an apparatus and a communication device. Background Art

[0002] In Integrated Sensing and Communication (ISAC) technology, there are two main approaches to waveform design for sensing signals: using communication waveforms and using radar waveforms. Radar waveforms are generally pulse waveforms with time-sharing transmission and reception, which effectively prevents interference from the transmitted signal on the echo signal. However, radar waveforms that enable long-range coverage (such as linear frequency modulation (LFM) waveforms) have large short-range blind spots, while waveforms with smaller short-range blind spots (such as ultra-wideband (UWB) waveforms) are unable to provide long-range coverage. Therefore, when sensing signals adopt radar waveform design methods, they cannot simultaneously meet the requirements for long-range and short-range coverage, resulting in poor sensing performance.

[0056] Before describing the embodiments of the present application, the following briefly introduces the relevant technologies:

[0057] 1. Communication and Perception Integration / Synesthesia Integration

[0058] Future 5G (Beyond 5G, B5G) and 6G wireless communication systems are expected to provide a variety of high-precision sensing services, such as indoor positioning for robot navigation, Wi-Fi sensing for smart homes, and radar sensing for autonomous vehicles. Sensing and communication systems are typically designed separately and occupy different frequency bands. Integrated Sensing and Communication (ISAC) enables sensing and communication systems to share the same frequency band and hardware, improving frequency efficiency and reducing hardware costs. ISAC will become a key technology for future wireless communication systems, supporting many important application scenarios. Typical applications of ISAC include navigation and obstacle avoidance for autonomous vehicles, Wi-Fi-based indoor positioning and activity recognition, communication and sensing for unmanned aerial vehicles, extended reality (XR), and radar and communication integration. Each application has different requirements, limitations, and regulatory issues. ISAC has attracted significant research interest and attention from both academia and industry.

[0059] ISAC achieves low-cost, integrated communication and perception capabilities through shared hardware and software-defined functions. Its key features include: a unified and simplified architecture; reconfigurable and scalable functions; and improved efficiency and reduced costs. The advantages of integrated communication and perception are threefold: reduced equipment cost and size; improved spectrum utilization; and enhanced system performance.

[0060] At present, typical communication perception integration scenarios that are expected to be achieved through technical upgrades based on the 5G communication system architecture are shown in Table 1.

[0061] Table 1 Typical scenarios of communication and perception integration

[0062]

[0063] According to the difference between the sending node and the receiving node of the sensing signal, there are 6 basic sensing methods. Figure 2 As shown, specifically including:

[0064] (1) Base station self-transmitting and self-receiving sensing: Base station A sends a sensing signal and performs sensing measurement by receiving the echo of the sensing signal.

[0065] (2) Inter-base station air interface sensing: Base station B receives the sensing signal sent by base station A and performs sensing measurements.

[0066] (3) Uplink air interface perception: Base station A receives the perception signal sent by terminal A and performs perception measurement.

[0067] (4) Downlink air interface perception: Terminal B receives the perception signal sent by base station B and performs perception measurement.

[0068] (5) Terminal self-transmitting and self-receiving perception: Terminal A sends a perception signal and performs perception measurement by receiving the echo of the perception signal.

[0069] (6) Sidelink perception between terminals: Terminal B receives the perception signal sent by terminal A and performs perception measurement.

[0070] It is worth noting that Figure 2 In the figure, each perception method takes a perception signal sending node and a perception signal receiving node as an example. In actual systems, one or more different perception methods can be selected according to different perception use cases and perception requirements, and each perception method can have one or more sending nodes and receiving nodes. Figure 2 The perception targets in the example are people and cars, and it is assumed that neither people nor cars carry or install signal receiving / transmitting equipment. The perception targets in actual scenes will be richer.

[0071] 2. Perceiving Waveforms

[0072] Waveform design is a key focus of research on synaesthesia integration technology, as waveform characteristics are closely linked to perception performance. Synaesthesia integration waveform design can be achieved by improving either the communication or perception waveform, enabling the communication waveform to support perception functions, or vice versa. However, this approach suffers from low resource utilization efficiency. Alternatively, new waveform designs can be used to integrate communication and perception functions into a single waveform, achieving an integrated design. The following analyzes several potential waveform approaches for synaesthesia integration.

[0073] (1) Commonly used communication waveforms. The design idea based on communication waveforms is to achieve the perception function while ensuring the efficiency of communication information transmission. Currently, common communication waveforms include Orthogonal Frequency Division Multiplexing (OFDM), Discrete Fourier Transform Spread-OFDM (DFT-s-OFDM), Single Carrier Frequency Domain Equalization (SC-FDE), or Filter Bank Multi-Carrier (FBMC).

[0074] As a typical multi-carrier modulation technology, OFDM waveform is widely used in 4G / 5G mobile communication systems. It has high spectrum efficiency and can perform flexible bandwidth resource allocation. When OFDM waveform is used for parameter estimation, there is no range-Doppler coupling effect. The Fourier transform-based detection algorithm at the receiving end is simple and efficient. In addition, the transmission mechanism of radar based on OFDM waveform is highly similar to that of communication system, which facilitates the realization of synaesthesia integrated design. However, OFDM waveform has problems such as high Peak to Average Power Ratio (PAPR) and sensitivity to Doppler and phase noise, which require targeted optimization. For example, the constant envelope OFDM (CE-OFDM) design can improve the problem of nonlinear distortion in high-power amplifiers caused by the high PAPR of traditional OFDM waveform.

[0075] By adding DFT expansion, the DFT-s-OFDM waveform can achieve single-carrier characteristics, thereby reducing PAPR. Research has applied frequency-domain spectral shaping (FDSS) to the DFT-s-OFDM waveform to further reduce out-of-band (OOB) emissions and inter-symbol interference (ISI), thereby improving perceptual performance.

[0076] For the IEEE 802.11ad system using the SC-FDE waveform, the Short Training Field (STF) and Channel Estimation Field (CEF) in its radio frame consist of complementary Golay sequences and are used for communication system frame synchronization, frequency offset estimation, and channel estimation. They can also be used for target detection, ranging, and speed measurement in radar systems.

[0077] In addition, some literature considers using FBMC as a communication perception fusion waveform. FBMC has good spectral characteristics and usually does not require a cyclic prefix. However, like OFDM, it suffers from the problem of high PAPR. To avoid inter-carrier interference (ICI), FBMC usually uses offset quadrature amplitude modulation (OQAM), which makes the calculation of perception information at the receiver relatively complex.

[0078] (2) Commonly used radar waveforms. The most widely used radar waveform at present is the frequency modulated continuous wave (FMCW). FMCW radar continuously transmits multiple chirp signals and detects the echo signals. Chirp signals are also called linear frequency modulation (LFM) signals. They are signals whose frequency changes linearly with time. They have the advantages of large time-bandwidth product, constant envelope, and good autocorrelation characteristics. Signal detection can be completed directly through the transmission and reception mixing method. The transceiver architecture and signal processing flow are simple. In order to enable FMCW to have communication functions, communication modulation data can be embedded in the FMCW waveform so that it carries communication information to achieve interawareness integration. For example, by changing the frequency modulation slope or starting frequency, it can carry communication information. In addition, the integrated design of synaesthesia based on commonly used radar waveforms can also be considered in combination with spatial modulation or generalized spatial modulation. For example, by selecting different transmitting antennas to carry communication information, changes to the characteristics of the perception signal itself can be avoided, minimizing the impact on perception performance. This includes combining it with the concept of Multiple Input Multiple Output (MIMO) radar. The orthogonal characteristics between transmitting antennas are more conducive to the demodulation of the communication information carried. The above-mentioned solutions for realizing communication functions based on FMCW waveforms generally have the disadvantage of low communication efficiency.

[0079] Of the six aforementioned sensing modes, the base station self-transmitting and self-receiving mode is similar to the operating mode of radar, making it easier to implement and a sensing mode strongly promoted by operators and equipment manufacturers. In this mode, the waveform design of the sensing signal mainly includes the following two methods:

[0080] Communication waveforms: Devices must have strong full-duplex capabilities to suppress interference from transmitted signals on echo signals. This interference can generally be eliminated through a combination of methods, including antenna isolation, analog cancellation, and digital cancellation.

[0081] Radar waveforms are typically pulse waveforms with time-sharing transmission and reception, which completely prevent the transmitted signal from interfering with the return signal. However, the LFM waveform, which provides long-range coverage, has a large blind spot at close range, while the UWB waveform, with its small blind spot at close range, cannot provide long-range coverage.

[0082] In view of this, the embodiments of the present application provide a perception method, a signal configuration method, an apparatus, and a communication device to solve the problem in the related art that the perception performance is poor because the perception signal cannot simultaneously meet the requirements of long-distance coverage and short-distance coverage.

[0083] The following describes in detail the sensing method and signal configuration method provided in the embodiments of the present application through some embodiments and their application scenarios in combination with the accompanying drawings.

[0084] Figure 3 A flow chart of a perception method provided by an embodiment of the present application is shown. Figure 3 As shown, the perception method includes the following steps:

[0085] Step 301: A first device obtains first information, where the first information includes configuration information of N target signals, where N is an integer greater than 1.

[0086] Step 302: The first device performs at least one of the following operations according to the first information: sending the N target signals, receiving the N target signals, and processing the received N target signals.

[0087] Among them, the N target signals are signals used for perception, each of the N target signals is used to cover a distance interval, the N distance intervals corresponding to the N target signals constitute a target distance interval, and the target distance interval is greater than the distance interval corresponding to any one of the N target signals.

[0088] The N target signals may be understood as sensing signals corresponding to one sensing operation, that is, the N target signals are used jointly as sensing signals. The sensing signals may be understood as signals used for sensing measurement.

[0089] Each of the N target signals covers a distance interval, and different target signals cover different distance intervals. Thus, the distance interval formed by the union of the N distance intervals corresponding to the N target signals is necessarily larger than the distance interval corresponding to any one of the N target signals. Thus, by using the N target signals in combination, the perception signal can cover a larger distance interval. Thus, by simply having one or more of the N target signals cover the short-range distance interval, and having one or more of the N target signals cover the long-range distance interval, the perception signal can simultaneously meet the requirements of long-range coverage and short-range coverage. By using the N target signals in combination, the distance coverage range (or perception range) of the perception signal can be expanded, thereby improving perception performance.

[0090] In the embodiment of the present application, the union of the N distance intervals corresponding to the N target signals can constitute the target distance interval. That is, the N distance intervals corresponding to the N target signals constitute the target distance interval. The target distance interval can be understood as a distance interval that meets the perception requirements. Therefore, according to the perception requirements, an appropriate number of target signals can be flexibly configured so that the N distance intervals corresponding to the configured N target signals constitute the target distance interval. In this way, by the joint use of N target signals, the distance interval covered by the perception signal can meet the required perception range, thereby ensuring perception performance.

[0091] In the embodiment of the present application, for the convenience of explanation, the kth target signal represents any one of the N target signals, k = 1, 2, ..., N. Then, the distance interval covered by the kth target signal can be understood as the distance range that can be covered by performing perception through the transmission, reception and processing of the kth target signal. For the convenience of explanation, the distance interval covered by the kth target signal is recorded as the kth distance interval, which can be expressed as [R k,min ,R k,max ]; where R k,min and R k,max Denote the near bound and far bound of the kth distance interval respectively. Then, the N distance intervals corresponding to the N target signals are the first distance interval, the second distance interval, ..., the Nth distance interval.

[0092] It should be noted that the terms "first," "second," and "Nth" do not imply a sequential order. That is, the order of the first distance interval, the second distance interval, ..., and the Nth distance interval is not limited to a sequence from far to near or from near to far. The N distance intervals corresponding to the N target signals can be continuous or discontinuous; any two distance intervals may or may not overlap, but this is not a limitation in the present embodiment.

[0093] In an embodiment of the present application, a first device obtains first information, where the first information includes configuration information of N target signals, where N is an integer greater than 1; the first device performs at least one of the following operations based on the first information: sending the N target signals, receiving the N target signals, and processing the received N target signals; wherein the N target signals are signals used for perception, each of the N target signals is used to cover a distance interval, the N distance intervals corresponding to the N target signals constitute a target distance interval, and the target distance interval is greater than the distance interval corresponding to any one of the N target signals. In this way, by jointly using the N target signals as perception signals, the coverage range of the perception signal can be expanded, and the perception signal can simultaneously meet the requirements of long-range coverage and short-range coverage, so that the distance interval covered by the perception signal can meet the required perception range, thereby further improving the perception performance.

[0094] In some embodiments, the target distance interval is a continuous distance interval, that is, the distance range of the target distance interval is [min{R k,min},max{R k,max}].

[0095] In this way, the perception range covered by the N target signals is a continuous perception range, which can ensure that the perception targets within the perception range are perceived, thereby further improving the perception performance.

[0096] Optionally, at least part of the first information is predefined by a protocol; or,

[0097] The first device obtains at least part of the first information from the second device.

[0098] That is, the manner in which the first device obtains the first information may include at least one of the following:

[0099] receiving first information from a second device;

[0100] The first information is obtained based on the agreement.

[0101] The first information may be entirely received from the second device, or entirely determined by a protocol, or partially received from the second device and partially determined by a protocol.

[0102] The second device may be a base station, or a sensing function (SF) network element (see explanation 1 below for details).

[0103] Optionally, the waveforms of the N target signals include at least one of the following waveforms:

[0104] OFDM waveform: It can be an OFDM signal used exclusively for sensing, or an OFDM signal used for both sensing and communication.

[0105] LFM waveform: includes LFM waveform (also known as chirp waveform) and FMCW waveform commonly used in radar.

[0106] UWB waveform.

[0107] Optionally, the waveform of any one of the N target signals is any one of the following: OFDM waveform, LFM waveform, UWB waveform.

[0108] That is to say, any one of the N target signals may be one of the following types of waveform signals: an OFDM waveform signal, an LFM waveform signal, or a UWB waveform signal.

[0109] It can be understood that any two target signals among the N target signals can be waveform signals of the same type among the three types of waveform signals mentioned above, or can be waveform signals of different types.

[0110] Optionally, any one of the N target signals is a pulse signal.

[0111] Figures 4a to 4b Figure 2 shows a schematic diagram of two pulse signals. Figure 4a As shown in , when the pulse signal includes more than one pulse, each pulse repeats periodically in time. The time interval between adjacent pulses is the pulse period, and the time length occupied by a single pulse is the pulse width. Figure 4b As shown in the figure, when the pulse signal consists of only one pulse, the duration of the pulse signal only includes one pulse period. Within one pulse period, the transmitter of the sensing signal transmits the sensing signal within the time range of the pulse width. Within one pulse period, the receiver of the sensing signal receives the sensing signal except for the time range of the pulse width (excluding the necessary switching time between transmission and reception).

[0112] In some embodiments, the present invention introduces a reference waveform (also known as a reference signal). The time parameters of any one of the N target signals are aligned with the time parameters of the reference waveform. That is, the target signal is time-aligned with the reference waveform. Because the reference waveform is an OFDM waveform, the reference waveform can be referred to as a reference OFDM waveform.

[0113] The target signal and the reference OFDM waveform are time-aligned in the following situations:

[0114] The time occupied by one pulse period of the target signal is aligned with the time occupied by one OFDM symbol period of the reference OFDM waveform, such as Figure 5a shown.

[0115] The time occupied by one pulse period of the target signal is aligned with the time occupied by multiple consecutive OFDM symbol periods of the reference OFDM waveform, such as Figure 5b shown.

[0116] The time occupied by multiple consecutive pulse periods of the target signal is aligned with the time occupied by one OFDM symbol period of the reference OFDM waveform, such as Figure 5c shown.

[0117] The time occupied by multiple consecutive pulse periods of the target signal is aligned with the time occupied by multiple consecutive OFDM symbol periods of the reference OFDM waveform, such as Figure 5d shown.

[0118] The OFDM symbol period described above includes a cyclic prefix and an OFDM symbol length; wherein the OFDM symbol length is equal to the inverse of the subcarrier spacing.

[0119] It should be noted that the reference OFDM waveform does not necessarily have an actual transmitted signal and is only used to configure the parameters of the target signal. Its parameters can be flexibly configured and can even exceed the limitation of the subcarrier spacing configuration μ specified in the NR protocol, which can only be 0 (corresponding to 15kHz subcarrier spacing) to 6 (corresponding to 960kHz subcarrier spacing).

[0120] It should also be noted that Figures 5a to 5d The illustration and corresponding description involve any one of the N target signals, that is, any one of the target signals is associated with a corresponding reference OFDM waveform, and the alignment of its time parameters satisfies any of the above situations.

[0121] The reference OFDM waveforms associated with any two target signals among the N target signals may be the same or different.

[0122] To better understand the time alignment relationship between the target signal and the reference OFDM waveform, the following description is made by taking the association between the kth target signal and the ith reference waveform as an example.

[0123] For the time alignment relationship between the kth target signal and the ith reference OFDM waveform, the following conditions must be met:

[0124] The pulse period of the kth target signal satisfy:

[0125] Among them, N krepresents the number of consecutive pulse periods in the kth target signal within the minimum time range within which the kth target signal is time-aligned with the i-th reference OFDM waveform; represents the number of consecutive OFDM symbol periods of the i-th reference OFDM waveform within the minimum time range in which the k-th target signal is time-aligned with the i-th reference OFDM waveform; represents the OFDM symbol period of the i-th reference OFDM waveform.

[0126] Combine Figures 5a to 5d An example is described as follows:

[0127] for Figure 5a In the case shown in , the minimum time range for time alignment between the kth target signal and the i-th reference OFDM waveform is one pulse period of the kth target signal or one OFDM symbol period of the i-th reference OFDM waveform (obviously, the time of two pulse periods of the kth target signal and two OFDM symbol periods of the i-th reference OFDM waveform is also aligned, and the minimum time range for time alignment is considered here). Then N k =1 and

[0128] for Figure 5b In the case shown in , the minimum time range for time alignment between the kth target signal and the i-th reference OFDM waveform is one pulse period of the kth target signal or two OFDM symbol periods of the i-th reference OFDM waveform (obviously, the two pulse periods of the kth target signal are also aligned with the four OFDM symbol periods of the i-th reference OFDM waveform, so the minimum time range for time alignment is considered here). Then N k =1 and

[0129] for Figure 5c In the case shown in , the minimum time range for time alignment of the kth target signal and the i-th reference OFDM waveform is 2 pulse periods of the kth target signal or 1 OFDM symbol period of the i-th reference OFDM waveform (obviously, the 4 pulse periods of the kth target signal and the 2 OFDM symbol periods of the i-th reference OFDM waveform are also aligned, so the minimum time range for time alignment is considered here). Then N k =2 and

[0130] for Figure 5dIn the case shown in , the minimum time range for time alignment of the kth target signal and the i-th reference OFDM waveform is 3 pulse periods of the kth target signal or 2 OFDM symbol periods of the i-th reference OFDM waveform (obviously, the 6 pulse periods of the kth target signal and the 4 OFDM symbol periods of the i-th reference OFDM waveform are also aligned, so the minimum time range for time alignment is considered here). Then N k =3 and

[0131] In the embodiment of the present application, by introducing a reference waveform, the target signal and the reference signal are time-aligned, so that the communication system using the OFDM waveform can be compatible with the perception signal in the embodiment of the present application, thereby achieving synaesthesia integration.

[0132] In an embodiment of the present application, the waveform of the target signal, the time parameters of the target signal, and other relevant parameters of the target signal can be configured through the first information. The following describes the various configuration information that the first information may include.

[0133] In some embodiments, the first information includes at least one of the following:

[0134] Information indicating the waveform of each target signal among the N target signals;

[0135] a pulse period of each target signal among the N target signals;

[0136] a subcarrier spacing of each reference waveform among M reference waveforms, each of the M reference waveforms being an orthogonal frequency division multiplexing (OFDM) waveform, where M is an integer greater than or equal to 1 and not greater than N;

[0137] The number of pulse cycles of the kth target signal within the minimum time length for the kth target signal to be time-aligned with the i-th reference waveform;

[0148] The i-th reference waveform is a reference waveform associated with the k-th target signal among the M reference waveforms, and i is a natural number from 1 to M.

[0149] The number of OFDM symbol periods of the i-th reference waveform corresponding to the pulse width of the k-th target signal can be understood as the number of OFDM symbol periods of the i-th reference waveform corresponding to the time length corresponding to the pulse width of the k-th target signal. The number of OFDM symbol periods of the k-th target signal included in the pulse width of the k-th target signal can be understood as the number of OFDM symbol periods of the k-th target signal included in the time length corresponding to the pulse width of the k-th target signal. Other identical or similar descriptions are understood the same and are not detailed here to avoid repetition.

[0150] After obtaining the first information, the first device can determine the pulse width of the kth target signal according to the content of the first information, which is recorded as After determining the pulse period of the kth target signal, it is necessary to further determine the pulse width of the kth target signal. The parameters included in the first information for further determining the pulse width of the kth target signal include one of the following:

[0153] The number of OFDM symbol periods of the target OFDM waveform (denoted as S k ).

[0154] Here, the target OFDM waveform represents the case where the kth target signal itself is an OFDM waveform signal. In this case, its pulse width can also be described by the number of OFDM symbol periods of the target OFDM waveform.

[0155] Specifically, given the pulse period of the kth target signal and duty cycle D k In the case of , the pulse width of the kth target signal is

[0156] Given that the kth target signal is aligned with the time parameters of the i-th reference OFDM waveform, the OFDM symbol period of the i-th reference OFDM waveform is In the case of , the pulse width of the kth target signal is

[0157] Given the number of OFDM symbol periods of the target OFDM waveform corresponding to the kth target signal (denoted as the kth target OFDM waveform), the pulse width in the kth target signal is in represents the OFDM symbol period of the kth target OFDM waveform.

[0158] It should be noted that the number of OFDM symbol periods of the OFDM waveform involved in this application can also be called the number of OFDM symbols of the OFDM waveform, and the two expressions can be understood in the same way.

[0159] The polarity of the frequency modulation slope of the kth target signal involved in the first information is described as follows:

[0160] When the waveform of the kth target signal is an LFM waveform, the polarity of the frequency modulation slope of the LFM waveform is positive or negative. k and pulse width After that, if the kth target signal is an LFM waveform, the absolute value of the frequency modulation slope is determined and is Its dimension is Hertz per second (Hz / s). When the polarity of the frequency modulation slope is positive, the frequency of the LFM waveform is within the bandwidth B. k In the range of B, it increases linearly; when the polarity of the frequency modulation slope is negative, the frequency of the LFM waveform is within the bandwidth B. k It decreases linearly within the range of .

[0161] The number of pulse cycles of the target signal involved in the first information can be understood as the number of pulse cycles of the target signal. In general, the number of pulse cycles in the kth target signal is N. k An integer multiple of .

[0162] The start time of the target signal involved in the first information may be expressed in one of the following ways:

[0163] Absolute time: can be an absolute time composed of at least one of a system frame number, a radio frame number, a half-frame number, a subframe number, a time slot number, and an OFDM symbol number.

[0164] Relative time: The offset relative to a specific time point. The offset value can be composed of at least one of the system frame number, radio frame number, half frame number, subframe number, time slot number, and OFDM symbol number.

[0165] In some embodiments, the sensing method further comprises:

[0166] The first device determines the pulse width of the kth target signal based on at least one of the following parameters:

[0167] The pulse period of the kth target signal;

[0168] a duty cycle of the pulses in the kth target signal;

[0169] The number of OFDM symbol periods of the i-th reference waveform corresponding to the pulse width of the k-th target signal;

[0170] When the waveform of the kth target signal is an OFDM waveform, the pulse width of the kth target signal includes the number of OFDM symbol periods of the kth target signal.

[0171] The specific manner in which the first device determines the pulse width of the kth target signal can be found in the above description of the pulse width of the kth target signal, which will not be elaborated on for the sake of repetition.

[0172] In some embodiments, the first information further includes at least one of the following:

[0173] The number of repetitions of the N target signals in the target perception frame;

[0174] The time interval between two adjacent repetitions of the N target signals in the target perception frame;

[0175] Periodically or semi-statically executing a repetition period corresponding to a target sensing frame;

[0176] First time information corresponding to the periodic execution of the target perception frame, where the first time information is used to indicate a start time when the first device executes the target perception frame;

[0177] Second time information corresponding to the semi-static execution target perception frame, the second time information being used to indicate a time interval between receipt of the activation signaling by the first device and sending, receiving, or signal processing of the first target perception frame;

[0178] The third time information corresponding to the non-periodic execution target perception frame; the third time information is used to indicate the time interval between the first device receiving the activation signaling and performing the sending, receiving or signal processing of the perception signal;

[0179] The type of activation signaling corresponding to the semi-static or semi-periodic execution of the target perception frame;

[0180] The executing target perception frame includes at least one of the following: executing sending of the target perception frame, executing receiving of the target perception frame, and executing processing of the target perception frame;

[0181] The target perception frame is formed by repeatedly sending the N target signals in the time domain.

[0182] As previously mentioned, a sensing signal consisting of N target signals can be referred to as a sensing signal burst. A sensing signal burst involves the transmission, reception, or signal processing of a sensing signal, enabling the measurement of the target's latency (or distance) and coarse Doppler (or velocity) measurements. To achieve fine Doppler (or velocity) or velocity measurements of a sensing target, the sensing signal burst must be repeated in the time domain to form a sensing frame. In other words, the target sensing frame is composed of repeated sensing signal bursts in the time domain.

[0183] Based on this, the number of repetitions of the N target signals in the target perception frame can be understood as the number of repetitions of the perception signal burst in time.

[0184] The time interval between two adjacent repetitions of the N target signals in the target sensing frame can be understood as the time interval between two temporally adjacent transmissions of sensing signal bursts. The time interval can be represented by at least one of a system frame number, a radio frame number, a half-frame number, a subframe number, a time slot number, and an OFDM symbol number.

[0185] Thus, the first device sends, receives or processes the perception signal according to the above instructions in the first information, and can complete the measurement of a target perception frame, thereby obtaining delay-Doppler information about the perception target or the perception target area.

[0186] Considering that in some scenarios it is necessary to repeatedly perform perception measurements of multiple perception frames, the first information may also be used to indicate a repetition method of the target perception frame.

[0187] In one embodiment, the first information is used to instruct the first device to periodically perform target sensing frame transmission, reception, or signal processing. In this case, the first information also includes at least one of the following:

[0188] Period: the repetition period of the target perception frame;

[0189] The first time information: that is, the start time of the target perception frame. Specifically, the start time of the first target perception frame can be an absolute time composed of at least one of the system frame number, communication frame number, half frame number, subframe number, time slot number, and OFDM symbol number, or an offset relative to a specific time point composed of at least one of the system frame number, communication frame number, half frame number, subframe number, time slot number, and OFDM symbol number.

[0190] In one embodiment, the first information is used to instruct the first device to semi-statically (or semi-continuously) perform the sending, receiving, or signal processing of the target perception frame, that is, after receiving the activation signaling, the first device periodically performs the sending, receiving, or signal processing of the target perception frame. In this case, the first information also includes at least one of the following:

[0191] Period: the repetition period of the target perception frame;

[0192] The second time information: that is, the effective time, specifically, the time interval between the first device receiving the activation signaling and the sending, receiving or signal processing of the first target perception frame, which can be composed of at least one of the system frame number, communication frame number, half frame number, subframe number, time slot number, and OFDM symbol number.

[0193] In one embodiment, the first information is used to instruct the first device to perform the transmission, reception, or signal processing of the target perception frame aperiodically, that is, the first device performs the transmission, reception, or signal processing of the target perception frame once after receiving the activation signaling. In this case, the first information also includes at least one of the following:

[0194] The third time information: that is, the effective time. Specifically, the time interval between the first device receiving the activation signaling and executing the sending, receiving or signal processing of the perception signal can be composed of at least one of the system frame number, communication frame number, half frame number, subframe number, time slot number, and OFDM symbol number.

[0195] The activation signaling may be layer 1 signaling, such as downlink control information (DCI); or layer 2 signaling, such as a medium access control (MAC) control element (CE); or layer 3 signaling, such as radio resource control (RRC) signaling.

[0196] Thus, the first device sends, receives or processes the perception signal according to the above instructions in the first information, and can complete periodic measurement, semi-periodic measurement or non-periodic measurement of the target perception frame, thereby obtaining delay-Doppler information about the perception target or the perception target area.

[0197] In some embodiments, the method further comprises:

[0198] The first device obtains second information, where the second information is used to instruct the first device to report the first measurement amount or the second measurement amount;

[0199] The first device sends target data to the second device according to the second information;

[0200] The first measurement amount is a measurement amount obtained by the first device based on each target signal of the N target signals;

[0201] The second measurement amount is a measurement amount obtained by the first device based on joint processing of the N target signals;

[0202] The target data includes at least one of the following:

[0203] the first measurement quantity;

[0204] the second measurement quantity;

[0205] an identifier of the first device;

[0206] Fourth time information, where the fourth time information is used to indicate at least one of the sending time and the receiving time of the N target signals.

[0207] The second information can be understood as measurement reporting configuration information, that is, the second information is used to indicate the measurement reporting behavior of the first device. Specifically, the second information is used to indicate that the first device needs to report at least one of the following:

[0208] First measurement quantity: a perception measurement quantity obtained by the first device through the transmission, reception, or processing of any one of the perception signals (i.e., N target signals) (see Explanation 2 below for details). In other words, the first measurement quantity may include perception measurement quantities obtained by the transmission, reception, or processing of one to a maximum of N target signals.

[0209] Second measurement quantity: a perception measurement quantity obtained by the first device through sending, receiving or processing perception signals (ie, N target signals).

[0210] Perceptual measurement quantities can be simply referred to as measurement quantities.

[0211] It is easy to understand that the first measurement quantity includes the measurement quantity obtained by sending, receiving or processing any target signal; and the second measurement quantity is the measurement quantity obtained by sending, receiving and jointly processing N target signals.

[0212] After the first device transmits, receives, or processes the sensing signal (i.e., N target signals), it may transmit target data to the second device based on the second information. The target data may include at least one of the first measurement quantity, the first measurement quantity, time information (used to indicate the time when the sensing signal was transmitted or received), and the ID of the first device.

[0213] The second device may be a base station or a SF network element.

[0214] In some embodiments, the second information is predefined by a protocol; or,

[0215] The first device obtains the second information from the second device.

[0216] It should be noted that the second information may be received entirely from the second device, or partially from the second device and partially as agreed upon by the protocol.

[0217] In some embodiments, the N target signals include a first target signal and a second target signal;

[0218] The first target signal is used to cover a first distance interval, and the second target signal is used to cover a second distance interval. The far boundary of the first distance interval is greater than the far boundary of the second distance interval, and the near boundary of the first distance interval is greater than the near boundary of the second distance interval.

[0219] Here, the N target signals include the first target signal and the second target signal, and are not limited to having only two target signals. That is, in addition to the first target signal and the second target signal, other target signals may also exist among the N target signals.

[0220] In one embodiment, the N target signals consist of two target signals, namely, a first target signal and a second target signal.

[0221] Optionally, the near boundary of the first distance interval is not greater than the far boundary of the second distance interval.

[0222] That is, the distance interval covered by the first target signal and the distance interval covered by the second target signal constitute a continuous distance interval.

[0223] Optionally, the first target signal is an LFM pulse signal, and the second target signal is a UWB pulse signal.

[0290] For details about the embodiments of this application, please refer to Figure 3 The relevant descriptions of the method embodiments are similar and can achieve the same technical effects, so they will not be described in detail to avoid repetition.

[0291] To facilitate understanding of the embodiments of the present application, the following specific embodiments are provided for illustrative purposes:

[0292] Example 1: The case where the perception signal consists of two target signals

[0293] In this embodiment, the perception signal is considered to be composed of two target signals, which are respectively denoted as a first target signal and a second target signal. Either the first target signal or the second target signal can be an OFDM waveform signal, an LFM waveform signal, or a UWB waveform signal. The first target signal and the second target signal can have the same waveform or different waveforms.

[0294] The distance range that can be covered by the transmission, reception and processing of the first target signal and the second target signal is recorded as the first distance interval and the second distance interval, which can be expressed as [R 1,min ,R 1,max ] and [R 2,min ,R 2,max ]; where R 1,min and R 1,max Represent the near and far bounds of the first distance interval, R 2,min and R 2,max They represent the near and far bounds of the second distance interval respectively.

[0295] For the convenience of description, without loss of generality, the far boundary of the first distance interval is greater than the far boundary of the second distance interval, that is, R 1,max >R 2,max At this time, it can be understood that the first target signal is responsible for long-distance coverage, and the second target signal is responsible for short-distance coverage. At this time, the following conditions need to be met: the short boundary of the first distance interval is not greater than the long boundary of the second distance interval, that is, R 1,min ≤R 2,max .

[0296] According to the above description, the relationship between the first distance interval and the second distance interval is as follows: Figures 7a and 7b shown.

[0297] Figure 7a In the case shown in FIG, the near boundary of the first distance interval is smaller than the far boundary of the second distance interval, so that the first target signal and the second target signal can be realized at a distance R 2,min To distance R 1,max There is continuous coverage between the first and second distance intervals, and the first distance interval and the second distance interval have a certain overlap.

[0298] Figure 7bIn the case shown in FIG, the near boundary of the first distance interval is equal to the far boundary of the second distance interval, so that the first target signal and the second target signal can also be realized at a distance R 2,min To distance R 1,max There is continuous coverage between the first and second distance intervals, but there is no overlap between the first distance interval and the second distance interval.

[0299] Obviously, by using the first target signal and the second target signal in combination, the distance coverage of the perception signal can be expanded (relative to any one of the first target signal and the second target signal).

[0300] To ensure compatibility of the perception signal in a communication system using an OFDM waveform, the time parameters of the first target signal and the second target signal need to be aligned with the time parameters of the reference OFDM waveform. For example, the time parameters of the first target signal are aligned with the time parameters of the first reference OFDM waveform, and the time parameters of the second target signal are aligned with the time parameters of the second reference OFDM waveform. For details on the method for aligning the time parameters, see the aforementioned related description.

[0301] Here, the first reference OFDM waveform and the second reference OFDM waveform can be the same or different. It is easy to understand that each reference OFDM waveform corresponds to a subcarrier spacing configuration. Assuming that the subcarrier spacing configuration of the first reference OFDM waveform is μ1 and the subcarrier spacing configuration of the second reference OFDM waveform is μ2, μ1 and μ2 can be the same or different. For example, the first target signal is aligned with the time parameters of the reference OFDM waveform with a 15kHz subcarrier spacing (i.e., μ1=0), and the second target signal is aligned with the time parameters of the reference OFDM waveform with a 30kHz subcarrier spacing (i.e., μ1=1).

[0302] According to the above description, when the time parameters of the first target signal are aligned with the time parameters of the first reference OFDM waveform, the following conditions are met: The time parameters of the second target signal are aligned with the time parameters of the second reference OFDM waveform when:

[0303] in, and Respectively represent the pulse periods of the first target signal and the second target signal;

[0304] N1 represents the number of consecutive pulse periods in the first target signal within the minimum time range within which the first target signal is time-aligned with the first reference OFDM waveform;

[0305] N2 represents the number of consecutive pulse periods in the second target signal within the minimum time range within which the second target signal is time-aligned with the second reference OFDM waveform;

[0306] represents the number of consecutive OFDM symbols of the first reference OFDM waveform within the minimum time range within which the first target signal is time-aligned with the first reference OFDM waveform;

[0307] represents the number of consecutive OFDM symbols of the second reference OFDM waveform within the minimum time range within which the second target signal is time-aligned with the second reference OFDM waveform;

[0308] and They represent the OFDM symbol periods of the first reference OFDM waveform and the second reference OFDM waveform respectively.

[0309] After the pulse periods of the first target signal and the second target signal are determined according to the above method, it is necessary to further determine the pulse widths of the first target signal and the second target signal.

[0310] Taking the first target signal as an example, the pulse width of the first target signal is Can be described by one of the following parameters:

[0311] The duty cycle of the first target signal (denoted as D1);

[0312] The number of OFDM symbol periods of the first reference OFDM waveform corresponding to the pulse width of the first target signal (denoted as L1);

[0313] Number of OFDM symbols of the first target OFDM waveform (denoted as S1): When the first target signal itself is an OFDM waveform (denoted as the target OFDM waveform), its pulse width can also be described by the number of OFDM symbols of the target OFDM waveform.

[0314] The pulse width of the second target signal is the same as that of the first target signal, and will not be described in detail.

[0315] Example 2: LFM pulse + UWB pulse

[0316] This embodiment is based on the first embodiment, and considers that the first target signal is an LFM waveform signal and the second target signal is a UWB waveform signal.

[0317] The first target signal covers the first distance interval, while the second target signal covers the second distance interval. The far boundary of the first distance interval is greater than the far boundary of the second distance interval. This means that the first target signal is responsible for detecting long-range targets, while the second target signal is responsible for detecting close-range targets.

[0318] On the one hand, according to the above related descriptions, according to the instruction of the first information, the first device generates an LFM pulse signal. The LFM pulse signal is aligned with the time of the first reference OFDM waveform in time, and the time of N1 LFM pulse periods is aligned with the time of the first reference OFDM waveform. That is, if the start time of the first LFM pulse period is aligned with the start time of the OFDM symbol period of the first reference OFDM waveform, then the end time of the N1th LFM pulse period is aligned with the end time of the N2th LFM symbol period. The end times of the OFDM symbol periods of the first reference OFDM waveforms are also aligned.

[0319] On the other hand, according to the above related descriptions, according to the instruction of the first information, the first device generates a UWB pulse signal. The UWB pulse signal is aligned in time with the time of the second reference OFDM waveform, and the time of the N2 UWB pulse cycles is aligned with the time of the second reference OFDM waveform. That is, if the start time of the first UWB pulse period is aligned with the start time of the OFDM symbol period of the first second reference OFDM waveform, then the end time of the N2th UWB pulse period is aligned with the end time of the N2th UWB pulse period. The end times of the OFDM symbol periods of the second reference OFDM waveforms are also aligned.

[0320] According to the provisions of 3GPP TS38.211, given that the subcarrier spacings of the first reference OFDM waveform and the second reference OFDM waveform are μ1 and μ2 respectively, an OFDM symbol period of the first reference OFDM waveform or the second reference OFDM waveform is:

[0321]

[0322] in, Indicates the OFDM symbol length, represents the cyclic prefix length, which satisfies the following formula:

[0323]

[0324]

[0325] Among them, T c =1 / (Δf max ·N f ), where Δf max =480×10 3 Hz and N f =4096;κ=64; Indicates the number of OFDM symbols in the subframe, where

[0326] In the above formula, for the first reference OFDM waveform, μ in the formula can be replaced by μ1; for the second reference OFDM waveform, μ in the formula can be replaced by μ2.

[0327] In one embodiment, the subcarrier spacing of the first reference OFDM waveform and the second reference OFDM waveform are both 30 kHz, i.e., μ1=μ2=1. Therefore, the LFM waveform and the UWB waveform are both aligned in time with the OFDM waveform with a subcarrier spacing of 30 kHz. Considering the normal cyclic prefix (NCP), according to the above formula, the OFDM symbol period of the OFDM waveform with a subcarrier spacing of 30 kHz is approximately 36.198 microseconds (μs) (l=0 or l=7·2 μ ) or 35.677μs(l≠0 and l≠7·2 μ ).

[0328] For the self-transmitting and self-receiving sensing mode, an echo delay of 1 μs corresponds to a detection distance of 150 m. Therefore, the echo delay of one OFDM symbol period of the OFDM waveform with a 30 kHz subcarrier spacing corresponds to a detection distance of more than 5 km. Figure 8 In the design, the first target signal includes 2 LFM pulses, which are time-aligned with a first reference OFDM symbol; the second target signal includes 8 UWB pulses, which are time-aligned with a second reference OFDM symbol.

[0329] In this example, the LFM pulse period is 18.099 μs (l = 0 or l = 7.2 μ ) or 17.8385μs (l≠0 and l≠7·2 μ ); the corresponding far boundary of the first distance interval is more than 2600, and the near boundary of the first distance interval is determined by the pulse width or duty cycle of the LFM pulse waveform. Assuming that the duty cycle D1 of the LFM waveform in the first target signal is 0.25, the near boundary of the first distance interval is about 679m (l=0 or l=7·2 μ ) or 669m(l≠0 and l≠7·2 μ ).

[0330] In this example, the UWB pulse period is 4.4596 μs (l≠0 and l≠7·2 μ ); the corresponding far boundary of the second distance interval is about 669m. The condition that the far boundary of the second distance interval is greater than or equal to the near boundary of the first distance interval is satisfied, that is, R 1,min ≤R 2,maxSimilarly, the near boundary of the second distance interval of the UWB waveform is determined by the pulse width or duty cycle of the UWB pulse waveform. Assuming the bandwidth of the UWB waveform is 400MHz, its pulse width is 1 / 400μs, and the corresponding near boundary of the second distance interval is 0.375m.

[0331] Through the design of this embodiment, the perception signal is composed of the first target signal and the second target signal, and the distance interval that can be covered is the union of the above-mentioned first distance interval and the second distance interval, that is, it can cover distance intervals as close as 0.375m and as far as 2600m or more.

[0332] Example 3: LFM pulse + OFDM pulse

[0333] This embodiment is based on Embodiment 1, and considers that the first target signal is an LFM waveform signal and the second target signal is an OFDM waveform signal.

[0334] The first target signal covers the first distance interval, while the second target signal covers the second distance interval. The far boundary of the first distance interval is greater than the far boundary of the second distance interval. This means that the first target signal is responsible for detecting long-range targets, while the second target signal is responsible for detecting close-range targets.

[0335] To reduce the close-range blind spot of the OFDM pulse waveform (i.e., the target OFDM waveform) in the second target signal, the target OFDM waveform needs to use a larger subcarrier spacing, for example, a 960kHz subcarrier spacing or larger. Since the target OFDM waveform is used to perform sensing services in the self-transmitting and self-receiving mode, its subcarrier spacing configuration can exceed the range of the NR protocol. For example, the subcarrier spacing is designed to be 7.68MHz (eight times 960kHz).

[0336] The analysis of the OFDM symbol periods of the first reference OFDM waveform and the second reference OFDM waveform is the same as that of Example 1.

[0337] In one embodiment, the subcarrier spacing of the first reference OFDM waveform and the second reference OFDM waveform are both 30 kHz, i.e., μ1=μ2=1. Therefore, the LFM waveform and the target OFDM waveform are both aligned in time with the OFDM waveform with a subcarrier spacing of 30 kHz. This embodiment can be performed as follows Figure 9 In the design, the first target signal includes 2 LFM pulses, which are time-aligned with a first reference OFDM symbol; the second target signal includes 8 OFDM pulses, which are time-aligned with a second reference OFDM symbol.

[0338] In this embodiment, the target OFDM waveform in the second target signal uses a subcarrier spacing of 7.68 MHz (eight times 960 kHz). The first distance interval of the first target signal in this embodiment is the same as that in Example 1, and the far boundary of the second distance interval of the second target signal is also the same as that in Example 1. In this embodiment, the near boundary of the second distance interval of the second target signal is determined by the OFDM symbol period of the target OFDM waveform. Using the same formula and calculation method as in Example 1, the near boundary of the second distance interval is approximately 20.9 m.

[0339] Through the design of this embodiment, the sensing signal consists of the first target signal and the second target signal. The range that can be covered is the union of the first and second distance ranges, that is, it can cover distances as close as 20.9 meters and as far as 2600 meters or more. Considering a typical configuration with a base station height of 25 meters, the short-range blind spot of 20.9 meters may not affect sensing services.

[0340] In summary, the embodiment of the present application uses N target signals jointly as perception signals, so that the perception signals can simultaneously meet the requirements of long-range coverage and short-range coverage, thereby improving perception performance.
