[0066] In some embodiments, network-side devices and terminals may have perception capabilities in addition to communication capabilities. Perception capabilities refer to one or more devices with the ability to sense the position, distance, speed, and other information of a target object through the transmission and reception of wireless signals, or to detect, track, identify, and image a target object, event, or environment. Some perception functions and application scenarios are shown in Table 1:
[0067] Table 1
[0068]
[0069] It should be noted that the perception categories shown in Table 1 above are only examples, and the embodiments of the present application do not limit the categories of perception measurements.
[0070] In addition, the embodiments of the present application can be applied to the communication and perception integration scenario, where communication and perception integration refers to the integrated design of communication and perception functions through spectrum sharing and hardware sharing in the same system. While transmitting information, the system can perceive information such as direction, distance, speed, and detect, track, and identify target devices or events. The communication system and the perception system complement each other to achieve overall performance improvement and bring a better service experience.
[0071] For example: the integration of communication and radar is a typical communication-perception integration (communication-perception fusion) application, and the integration of communication and radar systems can bring many advantages, such as cost savings, size reduction, power consumption reduction, spectrum efficiency improvement, and mutual interference reduction, thereby improving the overall performance of the system.
[0072] In the embodiment of the present application, according to the difference between the sensing signal sending node and the receiving node, it may include but is not limited to Figure 2 The six types of sensing links shown are as follows. Figure 2 Each perception link is illustrated by taking a sending node and a receiving node as an example. In actual systems, different perception links can be selected according to different perception requirements. Each perception link can have one or more sending nodes and receiving nodes, and the actual perception system can include multiple different perception links. 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.
[0073] Sensing link 1: The base station transmits and receives sensing signals autonomously. In this mode, the base station sends sensing signals and obtains sensing results by receiving the echo of the sensing signals.
[0074] Sensing link 2: inter-base station air interface sensing. In this mode, base station 2 receives the sensing signal sent by base station 1 and obtains the sensing result.
[0075] Perception link 3: Uplink air interface perception: In this mode, the base station receives the perception signal sent by the terminal and obtains the perception result.
[0076] Perception link 4: Downlink air interface perception: In this mode, the terminal receives the perception signal sent by the base station and obtains the perception result.
[0077] Perception link 5: Terminal self-transmitting and self-receiving perception. In this mode, the terminal sends a perception signal and obtains the perception result by receiving the echo of the perception signal.
[0078] Perception link 6: Sidelink perception between terminals. For example, terminal 2 receives a perception signal sent by terminal 1 and obtains a perception result, or terminal 1 receives a perception signal sent by terminal 2 and obtains a perception result.
[0079] In some embodiments, the signaling transmission between the wireless access network device and the terminal, or between different terminals, may be through Radio Resource Control (RRC) signaling or Medium Access Control Control Element (MAC CE) or Layer 1 signaling or other newly defined perception signaling; the signaling transmission between the perception network function and the terminal may be through Non-Access-Stratum (NAS) signaling (forwarded via AMF) or through RRC signaling or MAC CE or Layer 1 signaling or other newly defined perception signaling; the interaction between the perception network function and the base station may be forwarded to the wireless access network through the N2 interface by the AMF; or the core network perception network function may send it to the UPF, and the UPF may send it to the wireless access network through the N3 interface; or it may be sent to the wireless access network (such as a base station) through a newly defined interface; the signaling transmission between wireless access network devices may be through the Xn interface.
[0080] In some embodiments, the perception network function may also be called a perception network element or a perception management function (Sensing Management Function, Sensing MF), which may be located on the RAN side or the core network side. It refers to a network node in the core network or RAN responsible for at least one function such as perception request processing, perception resource scheduling, perception information interaction, and perception data processing. It may be based on an upgrade of the AMF or LMF in the mobile communication network, or it may be another network node or a newly defined network node. Specifically, the functional characteristics of the perception network function / perception network element may include at least one of the following:
[0081] Target information is exchanged with a wireless signal sending device or a wireless signal measuring device (including a target terminal or a serving base station of the target terminal or a base station associated with a target area), wherein the target information includes a perception processing request, a perception capability, perception assistance data, a perception measurement quantity type, a perception resource configuration information, etc., to obtain the value of the target perception result or the perception measurement quantity (uplink measurement quantity or downlink measurement quantity) sent by the wireless signal measuring device; wherein the wireless signal can also be referred to as a perception signal.
[0082] The perception method to be used is determined based on factors such as the type of perception service, perception service consumer information, required perception service quality (QoS) requirement information, the perception capability of the wireless signal sending device, and the perception capability of the wireless signal measuring device. The perception method may include: wireless access network device A sends and wireless access network device B receives, or the wireless access network device sends and the terminal receives, or the wireless access network device A sends and receives by itself, or the terminal sends and the wireless access network device receives, or the terminal sends and receives by itself, or terminal A sends and terminal B receives, etc.
[0083] The perception device serving the perception service is determined based on factors such as the type of perception service, information about the perception service consumer, required perception QoS requirement information, the perception capability of the wireless signal sending device, and the perception capability of the wireless signal measuring device. The perception device includes a wireless signal sending device or a wireless signal measuring device.
[0084] Manage the overall coordination and scheduling of resources required for sensing services, such as configuring sensing resources for wireless access network devices or terminals;
[0085] Data processing or calculation is performed on the values of the perceived measurement quantity to obtain the perceived result. The perceived result can also be verified and the perception accuracy can be estimated.
[0086] In some embodiments, radars can be categorized as monostatic and bistatic / multistatic, depending on whether the transmitter and receiver are separated. Bistatic radars generally require a significant distance between the transmitting and receiving antennas, comparable to the radar's operating range. Exo-radiation radars are a special case of bistatic radars. They utilize relevant electromagnetic wave detection theory and signal processing techniques to acquire non-cooperative electromagnetic signals transmitted by a third party (e.g., a communication base station) to detect, locate, track, and identify targets. These radars are also known as passive radars, bistatic / multistatic passive radars, passive radars, non-cooperative illuminating source radars, or non-cooperative passive detection systems.
[0087] Among them, the calculation of the bistatic radar perception result generally needs to be based on the reference channel (direct path) signal and the monitoring channel (reflection path) signal. The typical bistatic radar architecture diagram is as follows Figure 3 As shown. Among them, R Tis the distance from the signal transmitter (Tx) to the target, R R is the distance from the signal receiving end (Tx) to the target, L is the baseline distance, θ T is the angle of the target relative to the signal transmitter, θ R (θ R1 ,θ R2 ) is the angle of the target relative to the signal receiving end, and β is the bistatic angle.
[0088] In some embodiments, for common distance, Doppler, or speed measurements in perception measurements, measurement ambiguity may occur when the signal resource configuration does not meet the requirements. For example, for single-base radar perception, the relationship between the maximum unambiguous distance, Doppler, or speed and the signal resource configuration is:
[0089] If the speed direction is considered, the time domain resource interval satisfies ΔT≤1 / (2|f dmax |) or ΔT≤c / (4f c |v max |); If the time domain resource interval in the direction of speed is not considered and satisfies ΔT≤1 / f dmax Or ΔT≤c / (2f c v max ), where f dmax is the maximum unambiguous Doppler, v max is the maximum unambiguous velocity, f c is the carrier frequency and c is the speed of light.
[0090] Frequency domain resource spacing satisfies Δf≤1 / τ mmax Or Δf≤c / (2R max ), where τ max is the maximum unambiguous delay, R max is the maximum unambiguous distance.
[0091] For bistatic sensing, the relationship between the maximum unambiguous range, Doppler or speed and signal resource configuration is:
[0092] If the speed direction is considered, the time domain resource interval satisfies ΔT≤1 / (2|f dmax |) or If the time domain resource interval satisfies ΔT≤1 / f regardless of the speed direction dmax or β is the bistatic angle.
[0093] Frequency domain resource spacing satisfies Δf≤1 / τ max or where τ max is the maximum unambiguous delay, R max is the maximum unambiguous distance.
[0094] That is to say, when the frequency domain resource interval of the signal exceeds a certain value, ranging ambiguity will occur, and when the time domain resource interval exceeds a certain value, speed measurement / Doppler measurement ambiguity will be sent.
[0095] In the following, in combination with the accompanying drawings, a signal sending method, a signal receiving method, an apparatus and a device provided in the embodiments of the present application are described in detail through some embodiments and their application scenarios.

[0107] It is understandable that the perception signal and the communication signal may be the same or different. For example, for a synaesthesia integrated service, the perception signal and the communication signal may be the same.
[0108] The signal configuration information of the target signal may be configuration information related to the target signal, such as signal parameters and resource parameters of the target signal.
[0109] Step 402: The first device sends the target signal based on the signal configuration information. The target signal satisfies at least one of the following conditions:
[0110] The time domain resources of the target signal include at least one first time domain resource set, and further include l2 non-contiguous time domain resource units, the first time domain resource set includes l1 continuous time domain resource units, the l1 continuous time domain resource units and the l2 non-contiguous time domain resource units are different time domain resource units, l1 is an integer greater than 1, and l2 is an integer greater than or equal to 1;
[0111] The frequency domain resources of the target signal include at least one first frequency domain resource set, and also include k2 non-continuous frequency domain resource units, the first frequency domain resource set includes k1 continuous time domain resource units, the k1 continuous time domain resource units and the k2 non-continuous frequency domain resource units are different frequency domain resource units, k1 is an integer greater than 1, and k2 is an integer greater than or equal to 1.
[0112] The above-mentioned sending of the target signal based on the signal configuration information may be sending a target signal to the second device based on the signal configuration information, and the target signal is used for measurement by the second device or for transmitting information to the second device, or the target signal may be sent based on the signal configuration information, and the target signal is used for self-transmission and self-reception measurement by the first device.
[0113] The time domain resources of the target signal mentioned above refer to the time domain resources used to send the target signal, and the frequency domain resources of the target signal mentioned above refer to the frequency domain resources used to send the target signal.
[0114] The time domain resources of the above-mentioned target signal can be determined based on the above-mentioned signal configuration information, for example: the above-mentioned signal configuration information includes the time domain resource parameters of the target signal, or the time domain resources of the above-mentioned target signal can be determined based on pre-configuration information or information agreed upon in the protocol, such as the above-mentioned signal configuration information includes the waveform, transmission power, signal direction and other information of the above-mentioned target signal, and the pre-configuration information or the information agreed upon in the protocol includes the time domain resource parameters of the above-mentioned target signal.
[0115] The above-mentioned time domain resource units can be time domain resource units such as symbols, sub-slots, time slots, subframes, and frames.
[0116] The frequency domain resources of the above-mentioned target signal can be determined based on the above-mentioned signal configuration information, for example: the above-mentioned signal configuration information includes the frequency domain resource parameters of the target signal, or, the frequency domain resources of the above-mentioned target signal can be determined based on pre-configuration information or information agreed upon in the protocol, such as the above-mentioned signal configuration information includes the waveform, transmission power, signal direction and other information of the above-mentioned target signal, and the pre-configuration information or the information agreed upon in the protocol includes the frequency domain resource parameters of the above-mentioned target signal.
[0117] The frequency domain resource unit may be a resource element (RE), a resource block (RB), a physical resource block (PRB), or the like.
[0118] The values of l1, l2, k1, and k2 may be configured by the above-mentioned signal configuration information, or may be agreed upon by the protocol or pre-configured.
[0119] The target signal meeting at least one of the above items may include:
[0120] The time domain resources of the target signal include at least one first time domain resource set and further include 12 non-contiguous time domain resource units; or,
[0121] The frequency domain resources of the target signal include at least one first frequency domain resource set and also include k2 non-contiguous frequency domain resource units; or,
[0122] The time domain resources of the target signal include at least one first time domain resource set and also include l2 non-contiguous time domain resource units; and the frequency domain resources of the target signal include at least one first frequency domain resource set and also include k2 non-contiguous frequency domain resource units.
[0123] The above-mentioned 11 continuous time domain resource units and the 12 non-continuous time domain resource units are different time domain resource units, which can be understood as the 11 continuous time domain resource units and the 12 non-continuous time domain resource units do not overlap, that is, the time domain resource units included in any first time domain resource set do not have overlapping or identical time domain resources with the above-mentioned 12 non-continuous time domain resource units.
[0124] The above-mentioned k1 continuous time domain resource units and the k2 non-continuous frequency domain resource units are different frequency domain resource units, which can be understood as the k1 continuous time domain resource units and the k2 non-continuous frequency domain resource units do not overlap, that is, the frequency domain resource units included in any first frequency domain resource set do not have overlapping or identical time domain resources with the above-mentioned k2 non-continuous frequency domain resource units.
[0125] In some implementations, the time domain or frequency domain resources of the target signal are specifically designed based on the service characteristics of the target service to improve service performance, where the target service may include a perception service, a communication service, or a measurement service. For example, for a perception service, the time domain or frequency domain resources of the target signal are specifically designed based on the service characteristics of the perception service to improve perception performance.
[0126] In some embodiments, the time domain resources of the above-mentioned target signal may be time domain resources within a time domain interval, which may be referred to as a target time domain interval; the frequency domain resources of the above-mentioned target signal may be time domain resources within a frequency domain interval, which may be referred to as a target frequency domain interval, wherein the time domain interval or frequency domain interval may be agreed upon by protocol or configured on the network side.
[0127] In an embodiment of the present application, since the time domain resources of the target signal include at least one first time domain resource set and l2 non-continuous time domain resource units, l1 continuous time domain resource units and l2 non-continuous time domain resource units are configured for the target signal. In this way, the time domain resources of the target signal can be made more flexible through l1 continuous time domain resource units and l2 non-continuous time domain resource units, so as to better meet business needs, and the l2 non-continuous time domain resource units can avoid occupying too many time domain resources, so as to save resources, thereby improving resource utilization and further improving signal transmission performance. Since the frequency domain resources of the target signal include at least one first frequency domain resource set and k2 non-continuous frequency domain resource units, it is possible to configure k1 continuous frequency domain resource units and k2 non-continuous frequency domain resource units for the target signal. In this way, the frequency domain resources of the target signal can be made more flexible through k1 continuous frequency domain resource units and k2 non-continuous frequency domain resource units, so as to better meet business needs. In addition, the k2 non-continuous frequency domain resource units can avoid occupying too many frequency domain resources, so as to save resources, thereby improving resource utilization and further improving signal transmission performance.
[0128] For example, for measurement, ambiguity can be eliminated by measuring l1 consecutive time domain resource units in the first time domain resource set, that is, the ambiguity-free requirement is met to improve signal transmission performance. Moreover, since the time domain resources of the target signal include l2 non-contiguous time domain resource units, the non-contiguous time domain resource units can avoid occupying too many time domain resources, thereby saving time domain resource overhead in the absence of ambiguity to improve resource utilization. Alternatively, for measurement, ambiguity can be eliminated by measuring k1 consecutive frequency domain resource units in the first frequency domain resource set, that is, the ambiguity-free requirement is met to improve signal transmission performance. Moreover, since the frequency domain resources of the target signal include k2 non-contiguous frequency domain resource units, the non-contiguous frequency domain resources can avoid occupying too many frequency domain resources, thereby saving frequency domain resource overhead in the absence of ambiguity to improve resource utilization. When the target signal does not need to be measured, the first time domain resource set or the first frequency domain resource set can be used to achieve continuous transmission of the target signal, thereby improving the transmission reliability of the target signal.
[0129] For the above-mentioned target signal to be used for measurement, the following scenarios may be included:
[0130] Scenario 1: Dual-base sensing. In this scenario, the first device sends a target signal to the second device, which receives and measures it. The second device then reports the measurement results to the first device or a third device. The first and second devices can be terminals or base stations (or TRPs). Specifically, the first device can be a base station and the second device a terminal; or the first device can be a terminal and the second device can be a base station; or both the first and second devices can be base stations; or both the first and second devices can be terminals. The third device can be a core network perception network function or perception network element, or another base station or terminal.
[0131] In the second scenario, single-base sensing, a first device transmits a target signal and receives the echo for measurement. The first device then reports the measurement results to a third device. The first device can be a terminal or a base station (or TRP), and the third device can be a core network sensing network function or sensing network element, or another base station or terminal.
[0132] That is, in the embodiment of the present application, the first device is a signal sending device (for single-base perception, it is also a receiving device); the second device is a signal receiving device; and the third device is a device that participates in the perception service process but does not send or receive signals.
[0133] As an optional implementation, the interval between the time domain resource units within the second time domain resource set is a first time domain resource interval, the second time domain resource set includes the 12 non-contiguous time domain resource units and the Xth time domain resource unit in the first time domain resource set, and the first time domain resource interval is the time domain resource interval between the first resource unit and the Xth time domain resource unit, the first resource unit is the time domain resource unit closest to the Xth time domain resource unit among the 12 non-contiguous time domain resource units, and X is an integer.
[0134] Among them, the interval between the time domain resource units in the above-mentioned second time domain resource set is the first time domain resource interval, which can be understood as 12 non-continuous time domain resource units and the above-mentioned Xth time domain resource unit are equally spaced time domain resource units, and the interval between the 12 non-continuous time domain resource units and any adjacent time domain resource units in the above-mentioned Xth time domain resource unit is the above-mentioned first time domain resource interval.
[0135] The value of X may be determined by protocol agreement, the signal configuration information, or a network side indication.
[0136] For example: Figure 5 For example, Figure 5 A time domain resource region includes a first time domain resource set and two non-contiguous time domain resource units, and the time domain resource region is represented by T p, wherein the first time domain resource set includes 4 consecutive time domain resource units, such as Figure 5 As shown in a and b in , the interval between the first time domain resource and the non-continuous time domain resource unit in the first time domain resource set is the above-mentioned first time domain resource interval, such as Figure 5 As shown in c and d, the interval between the second time domain resource and the non-continuous time domain resource unit in the first time domain resource set is the above-mentioned first time domain resource interval.
[0137] For example: Figure 6 For example, Figure 6 A time domain resource region includes two first time domain resource sets and two non-contiguous time domain resource units. The time domain resource region is represented by T p , wherein the first time domain resource set includes 4 consecutive time domain resource units, such as Figure 6 As shown in a and b, the interval between the first time domain resource and the non-continuous time domain resource unit in the two first time domain resource sets is the above-mentioned first time domain resource interval.
[0138] In some implementations, the first time domain resource interval may also be referred to as a first sending period ΔT1.
[0139] In some implementations, the Xth time domain resource unit in the first time domain resource set belongs to both the first time domain resource set and the second time domain resource set, and may be recorded as a common time domain resource unit.
[0140] In one of the above optional implementations, since the time domain resource interval of the 12 non-continuous time domain resource units is the same as the first time domain resource interval, it can be achieved that the 12 non-continuous time domain resource units and the above-mentioned Xth time domain resource unit are equally spaced, so that the target signal is periodically sent on the 12 non-continuous time domain resource units and the above-mentioned Xth time domain resource unit. In this way, when measurement is performed based on the 12 non-continuous time domain resource units and the above-mentioned Xth time domain resource unit (that is, measurement is performed based on the second time domain resource set), the overall resource length of the measurement is longer (that is, the resource length spanned between the 12 non-continuous time domain resource units and the above-mentioned Xth time domain resource unit), and the longer overall resource length can better guarantee the resolution requirements, thereby improving the measurement performance.
[0141] As an optional implementation, when the time domain resources of the target signal include multiple first time domain resource sets, the time domain resource intervals between adjacent first time domain resource sets in the multiple first time domain resource sets are the same and are the second time domain resource intervals.
[0142] The second time domain resource interval may also be referred to as a second transmission period ΔT2, that is, the target signal is periodically transmitted on the plurality of first time domain resource sets, thereby reducing the complexity of receiving the target signal and being more conducive to measurement.
[0143] In some embodiments, the time domain resources of the above-mentioned target signal include multiple first time domain resource sets, which may be that the target signal includes multiple first time domain resource sets within a time domain resource interval, such as including multiple first time domain resource sets within a coherent processing time window or a time domain resource interval configured on the network side.
[0144] As an optional embodiment, there is at least one coherent processing time window in the time domain resources of the target signal, each coherent processing time window includes at least one of the first time domain resource sets or 12 non-continuous time domain resource units, and the length of the coherent processing window is the length of the time domain resources used to calculate a measurement result.
[0145] The length of the coherent processing time window may be agreed upon by a protocol or configured on the network side, or determined by the first device or the second device.
[0146] The length of the above-mentioned coherent processing window is the time domain resource length used to calculate a measurement result. It can be understood that the target signal sent by the first device in the time domain resource length is used to calculate a measurement result, that is, the coherent processing window is the time window corresponding to each calculation of the measurement result. For example, the receiving end performs a two-dimensional fast Fourier transform (FFT operation) to obtain the signal time domain resource corresponding to the delay-Doppler map. Specifically, the above-mentioned coherent processing time window may include multiple time slots or symbols.
[0147] for Figure 5 or Figure 6 In the scenario shown, the length of the coherent processing window can be as follows: Figure 5 or Figure 6 T shown in p .
[0148] The above-mentioned inclusion of at least one of the first time domain resource sets or l2 non-continuous time domain resource units in each coherent processing time window can be understood as that the time domain resources of the target signal in each coherent processing time window include at least one of the first time domain resource sets or l2 non-continuous time domain resource units, such as Figure 5 A coherent processing time window includes a first time domain resource set and two non-contiguous time domain resource units, such as Figure 6 A coherent processing time window includes two first time domain resource sets and two non-contiguous time domain resource units.
[0149] In the above implementation, since each coherent processing time window includes at least one of the first time domain resource sets or 12 non-continuous time domain resource units, there is sufficient time to calculate the measurement results during the measurement process to improve the reliability of the measurement.
[0150] Optionally, the length of the coherent processing window satisfies at least one of the following:
[0151]
[0152] or,
[0153] Where Δf d is the Doppler resolution, Δv is the velocity resolution, T p is the length of the coherent processing window, λ is the signal wavelength, and β is the bistatic angle.
[0154] The Doppler resolution and velocity resolution may be determined by protocol agreement, network configuration, or pre-configuration.
[0155] Since the length of the coherent processing window satisfies at least one of the above items, the transmission of the target signal can meet the requirements of Doppler resolution or velocity resolution, thereby further improving the signal transmission performance or measurement performance.
[0156] In some implementations, the length of the coherent processing window may also be a protocol agreement or a network-side configuration.
[0157] In some implementations, the position of the first time domain resource set within the time domain interval is configurable, and the starting position can be T offset1 Indicates that the position of the second time domain resource set in the time domain interval is configurable and can be set with the starting position T offset2 It can also be represented by the starting position T of the above-mentioned common time domain resource unit in the first time domain resource set. offset3 express.
[0158] For example, for Figure 5 a, T offset1 =T offset2 =T offset3 =0;
[0159] for Figure 5 b, T offset1 =ΔT1, T offset2 =T offset3 =0;
[0160] for Figure 5 c, T offset1 =ΔT1-Tsym , T offset2 =0, T offset3 =T sym , T sym Indicates an offset of one time domain resource unit length, for example, an offset of one orthogonal frequency division multiplexing (OFDM) symbol;
[0161] for Figure 5 d, T offset1 =0, T offset2 =T offset3 =T sym .
[0162] In some embodiments, in a target time domain interval (e.g. Figure 5 or 6 neutralization T p ) is N1=1 or N1>1, wherein the number of the first time domain resource sets is 1 to save resources. A number of first time domain resource sets greater than 1 can improve signal transmission or measurement performance. For example, when the interference of the first first time domain resource set is relatively large or the signal is in deep fading, better measurement performance can be achieved by using the second first time domain resource set.
[0163] In some implementations, when the number of first time domain resource sets N1=2 within the target time domain interval, the two first time domain resource sets may be adjacent (i.e., the time domain interval is ΔT1), such as Figure 6 As shown in a, the target time domain interval T p The first and second resource units of the second time domain resource set are common time domain resource units; they can also be placed in the first time domain interval T p The starting and ending positions, such as Figure 6 As shown in b, the target time domain interval T p The first and last time domain resource units in the second time domain resource set are common time domain resource units.
[0164] As an optional implementation, the interval between the frequency domain resource units in the second frequency domain resource set is the first frequency domain resource interval, the second frequency domain resource set includes the k2 non-contiguous frequency domain resource units and the Yth time domain resource unit in the first frequency domain resource set, and the first frequency domain resource interval is the frequency domain resource interval between the second resource unit and the Yth frequency domain resource unit, the second resource unit is the frequency domain resource unit closest to the Yth frequency domain resource unit among the k2 non-contiguous frequency domain resource units, and Y is an integer.
[0165] Among them, the interval between the frequency domain resource units in the above-mentioned second frequency domain resource set is the first frequency domain resource interval, which can be understood as the k2 non-continuous frequency domain resource units and the above-mentioned Yth frequency domain resource unit are equally spaced, and the interval between the k2 non-continuous frequency domain resource units and any adjacent frequency domain resource units in the above-mentioned Yth frequency domain resource unit is the first frequency domain resource interval.
[0166] The value of Y mentioned above may be determined by protocol agreement, configuration of the signal configuration information, or indication from the network side.
[0167] In some implementations, the first frequency domain resource interval may also be represented by a first frequency domain density (Density) 1, for example, Density 1 is used to represent each RB or each target frequency domain interval F p The number of frequency domain resource units (belonging to the second frequency domain resource set) in the frequency domain resource set.
[0168] In some implementations, the Yth frequency domain resource unit in the first frequency domain resource set belongs to both the first frequency domain resource set and the second frequency domain resource set, and can be recorded as a common frequency domain resource unit.
[0169] In the above-mentioned optional implementation manner, since the frequency domain resource interval of the k2 non-continuous frequency domain resource units is the same as the first frequency domain resource interval, it can be achieved that the k2 non-continuous frequency domain resource units and the above-mentioned Yth frequency domain resource unit are equally spaced, so that when measurements are performed based on the k2 non-continuous frequency domain resource units and the above-mentioned Yth frequency domain resource unit (that is, measurements are performed based on the second frequency domain resource set), the overall resource length of the measurement is longer (that is, the resource length spanned between the k2 non-continuous frequency domain resource units and the above-mentioned Yth frequency domain resource unit), and the longer overall resource length can better guarantee the resolution requirements, thereby improving the measurement performance.
[0170] As an optional implementation, when the frequency domain resources of the target signal include multiple first frequency domain resource sets, the frequency domain resource intervals between adjacent first frequency domain resource sets in the multiple first frequency domain resource sets are the same and are the second frequency domain resource intervals.
[0171] In some implementations, the second frequency domain resource interval may also be referred to as a second Density2. For example, Density2 is used to represent each target frequency domain interval F. p The number of the first resource set in the directory.
[0172] Since the frequency domain resource intervals between adjacent first frequency domain resource sets in multiple first frequency domain resource sets are the same, the above-mentioned target signal can be sent at intervals on the above-mentioned multiple first frequency domain resource sets, thereby reducing the complexity of receiving the target signal and being more conducive to measurement.
[0173] As an optional implementation manner, the bandwidth of the frequency domain resource of the target signal is the bandwidth of the target signal, and the bandwidth of the target signal satisfies at least one of the following:
[0174]
[0175] or,
[0176] Wherein, Δτ is the delay resolution, ΔR is the range resolution, B is the bandwidth of the target signal, c is the speed of light, and β is the bistatic angle.
[0177] The above delay resolution and distance resolution may be agreed upon by the protocol or configured or pre-configured on the network side.
[0178] Since the bandwidth of the target signal satisfies at least one of the above conditions, the transmission of the target signal can meet the requirements of delay resolution or distance resolution, thereby further improving the signal transmission performance or measurement performance.
[0179] In some implementations, the length of the coherent processing window may also be a protocol agreement or a network-side configuration.
[0180] In some implementations, the position of the first frequency domain resource set within the target frequency domain interval is configurable, and the starting position may be F. offset1 Indicates that the position of the second frequency domain resource set in the target frequency domain interval is configurable and can be set with the starting position as F offset2 It can also be the starting position F of the above-mentioned common frequency domain resource unit in the first frequency domain resource set. offset3 express.
[0181] As an optional implementation manner, the target signal is used for measurement, and the method further includes at least one of the following:
[0182] The first device obtains measurement configuration information;
[0183] The first device sends measurement configuration information to the second device;
[0184] The measurement configuration information includes at least one of the following:
[0185] Measurement resource indication information, measurement rule information, perception measurement quantity information, and reporting configuration information.

[0187] The above measurement can be that the first device sends the above target signal and the second device performs the measurement, or the first device sends the target signal and the first device performs the measurement based on the echo of the target signal, that is, self-transmission and self-reception.
[0188] The above-mentioned first device obtaining the measurement configuration may be that the first device obtains measurement configuration information sent by a third device, and the third device may be a terminal, a network side device or a core network device, such as a perception network function.
[0189] For example: in a scenario where the first device sends a target signal to the second device, and the second device receives and performs measurement, before the first device sends the target signal to the second device, the first device sends measurement configuration information to the second device, or the third device sends measurement configuration information to the second device; for a scenario where the first device sends a target signal and receives an echo for measurement, before the first device sends a target signal and receives an echo for measurement, the third device sends measurement configuration information to the first device.
[0190] In the above implementation, obtaining the measurement configuration information allows the first device to perform measurement based on the measurement configuration information to improve measurement performance, or sending the measurement configuration information to the second device allows the second device to perform measurement based on the measurement configuration information to improve measurement performance.

[0207] The measurement results corresponding to the first time domain resource set and the second time domain resource set can be obtained by performing measurements based on the first time domain resource set and the second time domain resource set respectively.
[0208] A joint measurement result of the first time domain resource set and the second time domain resource set may be obtained by performing joint measurement based on the first time domain resource set and the second time domain resource set.
[0209] Measurements are performed based on the first frequency domain resource set and the second frequency domain resource set, respectively, to obtain measurement results corresponding to the first frequency domain resource set and the second frequency domain resource set, respectively.
[0210] A joint measurement result of the first frequency domain resource set and the second frequency domain resource set may be obtained by performing joint measurement based on the first frequency domain resource set and the second frequency domain resource set.
[0211] Through the above-mentioned separate measurement and joint measurement, different measurement methods can be configured for different services or scenarios, so as to meet the needs of more services or scenarios.
[0212] The measurement threshold information is used to indicate the threshold information required to be used during the measurement process. The measurement threshold information can be more easily matched with the current measurement through the measurement threshold information, thereby improving measurement performance.
[0213] In some implementations, the measurement threshold information may include at least one of threshold value information and parameter information related to threshold calculation.
[0214] The threshold value information may indicate a threshold used by the first device or the second device during the measurement process, for example, a threshold for determining a path, or a threshold for detecting a target.
[0215] The parameter information related to the threshold calculation is parameter information used to calculate the threshold, so that the first device or the second device calculates the threshold value based on the parameter information.

[0225] The parameter information related to the threshold calculation can enable the first device or the second device to determine the threshold used in the measurement process, so that the threshold is more closely matched with the current measurement, thereby improving measurement performance.
[0226] The time domain measurement window information is used to indicate the time domain window in the measurement. For example, the time domain measurement window information includes at least one of the following:
[0227] Information of a time domain measurement window associated with the first time domain resource set;

[0394] The frequency domain resources of the target signal meet the maximum unambiguous measurement requirements.
[0395] The time domain resource of the target signal meeting the maximum unambiguous measurement requirement may be that the time domain resource of the target signal meets the maximum unambiguous measurement range requirement, such as that the time domain resource interval of the time domain resource of the target signal meets the maximum unambiguous Doppler requirement or the maximum unambiguous speed requirement. For example:
[0396] For single-base radar perception, if the speed direction is considered, the time domain resource interval of the target signal time domain resource satisfies ΔT≤1 / (2|f dmax |) or ΔT≤c / (4f c |v max |); If the time domain resource interval in the direction of speed is not considered and satisfies ΔT≤1 / f dmax Or ΔT≤c / (2f c v max ), where f dmax is the maximum unambiguous Doppler, v max is the maximum unambiguous velocity, f c is the carrier frequency and c is the speed of light.
[0397] For bistatic sensing, if the speed direction is considered, the time domain resource interval of the target signal’s time domain resource satisfies ΔT≤1 / (2|f dmax |) or If the time domain resource interval satisfies ΔT≤1 / f regardless of the speed direction dmax or β is the bistatic angle.

For example:
[0399] For single-base radar perception, the frequency domain resource interval of the target signal's frequency domain resource satisfies Δf≤1 / τ mmax Or Δf≤c / (2R max ), where τ max is the maximum unambiguous delay, R max is the maximum unambiguous distance.
[0400] For bistatic sensing, the frequency domain resource interval of the target signal's frequency domain resources satisfies Δf≤1 / τ max or where τ max is the maximum unambiguous delay, R max is the maximum unambiguous distance.
[0401] Since the time domain resources of the target signal meet the maximum unambiguous measurement requirement or the frequency domain resources of the target signal meet the maximum unambiguous measurement requirement, the measurement performance can be improved.
[0402] As an optional implementation, the value of l1 includes the following: 2, 6, 10, 14;
[0404] or,
[0405] The first time domain resource interval of the 12 non-contiguous time domain resource units includes the following:
[0406] 1 reference resource unit, 5 reference resource units, 10 reference resource units;
[0407] The first time domain resource interval is a time domain resource interval between a first resource unit and an Xth time domain resource unit in the first time domain resource set, the first resource unit being the time domain resource unit closest to the Xth time domain resource unit among the 12 non-contiguous time domain resource units, where X is an integer;
[0408] The time domain resource unit is a sub-resource unit of the reference resource unit.
[0409] The reference resource unit may be a time slot, a subframe or a frame, and the sub-resource unit may be a symbol, a sub-time slot or a time slot.
[0410] The value of l1 is 2, 6, 10, or 14, so that a first time-domain resource set includes 2, 6, 10, or 14 resource units, such as 2, 6, 10, or 14 symbols. The inclusion of 2, 6, 10, or 14 resource units in a first time-domain resource set can ensure an unambiguous measurement range requirement.
[0411] The time domain resource interval of the above 12 non-contiguous time domain resource units includes 1 reference resource unit, 5 reference resource units or 10 reference resource units, which can ensure the resolution requirement and also save transmission resources to improve transmission resource utilization.
[0412] In an embodiment of the present application, a first device determines signal configuration information of a target signal; the first device sends the target signal based on the signal configuration information, and the target signal satisfies at least one of the following items: the time domain resources of the target signal include at least one first time domain resource set, and also include l2 non-continuous time domain resource units, the first time domain resource set includes l1 continuous time domain resource units, the l1 continuous time domain resource units and the l2 non-continuous time domain resource units are different time domain resource units, l1 is an integer greater than 1, and l2 is an integer greater than or equal to 1; the frequency domain resources of the target signal include at least one first frequency domain resource set, and also include k2 non-continuous frequency domain resource units, the first frequency domain resource set includes k1 continuous time domain resource units, the k1 continuous time domain resource units and the k2 non-continuous frequency domain resource units are different frequency domain resource units, k1 is an integer greater than 1, and k2 is an integer greater than or equal to 1. Since the time domain resources of the target signal include at least one first time domain resource set and l2 non-continuous time domain resource units, it is possible to configure l1 continuous time domain resource units and l2 non-continuous time domain resource units for the target signal. In this way, the time domain resources of the target signal can be made more flexible through l1 continuous time domain resource units and l2 non-continuous time domain resource units, so as to better meet business needs. In addition, the l2 non-continuous time domain resource units can avoid occupying too many time domain resources, so as to save resources, thereby improving resource utilization and further improving signal transmission performance. Since the frequency domain resources of the target signal include at least one first frequency domain resource set and k2 non-continuous frequency domain resource units, it is possible to configure k1 continuous frequency domain resource units and k2 non-continuous frequency domain resource units for the target signal. In this way, the frequency domain resources of the target signal can be made more flexible through k1 continuous frequency domain resource units and k2 non-continuous frequency domain resource units, so as to better meet business needs. In addition, the k2 non-continuous frequency domain resource units can avoid occupying too many frequency domain resources, so as to save resources, thereby improving resource utilization and further improving signal transmission performance.

Figure 4 The relevant descriptions of the embodiment shown are not repeated in this embodiment to avoid duplication.
[0514] The following uses perception measurement as an example to illustrate the method provided in the embodiments of the present application through multiple embodiments:
[0515] Example 1:
[0516] In this embodiment, the time domain and frequency domain resource configuration of an OFDM system target signal is used as an example for description.
[0517] To support the unambiguous measurement range and resolution requirements in sensory signal design while minimizing sensory signal overhead, in this embodiment, the first time-domain (or frequency-domain) resource set corresponds to a set of contiguous resource units, ensuring the unambiguous measurement range requirement. The second time-domain (or frequency-domain) resource set has relatively large resource intervals, but a longer overall resource length, ensuring the resolution requirement. In this embodiment, the time-domain resource configuration is used as an example (i.e., the time-domain dimension adopts the design method described in the inventive solution, and the frequency-domain dimension adopts a uniform resource pattern design) to specifically describe the time-domain and frequency-domain resource parameter configurations for the target signal in an OFDM system.
[0518] An example of the time-frequency domain resources of the target signal in an OFDM system is as follows: Figure 8 As shown, where:
[0519] The target signal bandwidth is configured as 273 RBs, and the frequency domain resource density Density1 = 1 (one subcarrier out of 12 subcarriers in each RB is used to carry the target signal), which is also represented by the frequency domain resource interval, that is, the frequency domain resource interval ΔF1 = 12 (subcarriers); the frequency domain starting position of the target signal is Foffset1 =0 (the frequency domain offset relative to the starting subcarrier of the RB where it is located is 0 subcarriers).
[0520] The first time domain resource interval or the first transmission period ΔT1=1 (slot), which can also be expressed by the number of radio frames, subframes, half frames, etc.;
[0521] The second time domain resource interval or the second transmission period ΔT2=80 (slots), which can also be expressed in radio frames, subframes, half frames, etc.;
[0522] The starting position T of the first time domain resource set offset1 , may refer to the starting symbol in the first time domain resource set relative to the first time domain interval T p The offset, T offset1 =1 (OFDM symbol); it can also refer to the offset of the starting symbol in the first time domain resource set relative to slot0, that is, T offset1 =1(OFDM symbol);
[0523] The starting position T of the second time domain resource set offset2 , may refer to the starting symbol in the second time domain resource set relative to the first time domain interval T p The offset, T offset2 =1 (OFDM symbol); it can also refer to the offset of the starting symbol in the second time domain resource set relative to slot0, that is, T offset2 =1(OFDM symbol);
[0524] The starting position of the common time domain resource unit T offset3 , can refer to the offset of the common time domain resource unit relative to the starting position of the first time domain resource set in the same time slot, that is, T offset3 =1 (OFDM symbol); it can also refer to the offset of the common time domain resource unit relative to slot0, that is, T offset3 =2 (OFDM symbols);
[0525] The number of continuous time domain resource units in the first time domain resource set is l1=6;
[0526] The first time domain interval T p The number of non-contiguous time domain resource units l2=80;
[0527] The first time domain interval T p The number of the first time domain resource sets n1=1;
[0528] The time domain or frequency domain resource configuration of the target signal needs to avoid the resources occupied by communication reference signals (CSI-RS, DMRS, SRS, etc.) or synchronization signals (SSB).
[0529] Optionally, at least one of the above parameters may be preset or agreed upon by protocol, for example, the time slot (slot) #A corresponding to the resource unit of the second time domain resource set satisfies the first relationship: (A mod 5) = 0, and the corresponding symbol is the last OFDM symbol in slot #A. That is, the first sending period ΔT1 = 5 (slots). After the target signal is configured, or after the target signal is configured and activated through signaling such as MAC CE, the signal corresponding to the second time domain resource set is fixedly sent on the last OFDM symbol of the time slot that satisfies the first relationship; the number of OFDM symbols contained in the first time domain resource set is l1 = 2, 6, 10, 14, which is configurable, and the last OFDM symbol also belongs to the second time domain resource set, and the sending period ΔT2 = T of the first time domain resource set. p This is also configurable and can be expressed as ΔT2 = M·ΔT1, meaning the signal transmission period of the first time domain resource set is equal to the signal transmission period of M resource units in the second time domain resource set. The starting position of the first time domain resource set can default to the nearest time slot #A that satisfies the first relationship after the target signal is configured, or after the target signal is configured and activated via signaling such as MAC CE. Alternatively, the starting position of the first time domain resource set defaults to after the target signal is configured.
[0530] Or after configuring the target signal and activating it through MAC CE and other signaling, the first relationship is satisfied. slot#A, where Indicates that X is rounded down.
[0531] Optionally, at least one typical target signal time / frequency domain resource pattern may be preset, and different target signal time / frequency domain resource patterns may correspond to (at least one) time domain resource parameter, or frequency domain resource parameter, which is different. At this time, the target signal configuration may be performed by indicating the target signal resource pattern index. The correspondence between the resource pattern index and the resource pattern associated parameter may be agreed upon in advance by the transceiver devices, such as specified in the protocol, or may be notified in advance by the first device to the second device (for example, by indicating the specific time / frequency domain resource parameters corresponding to different resource pattern indexes through RRC signaling, and indicating the index value (and other target signal configuration-related parameters) through layer 1 signaling).
[0532] Example 2:
[0533] This embodiment is described by taking another example of time domain and frequency domain resource configuration of an OFDM system target signal.
[0534] This embodiment provides a method for configuring multiple signal resources as target signals and indicating a perception measurement method. Assume that the time domain resource parameters and frequency domain resource parameters of the target signal are:
[0535] The target signal bandwidth is configured as 273 RBs, and the frequency domain resource density Density1 = 1 (one subcarrier out of 12 subcarriers in each RB is used to carry the target signal), which is also represented by the frequency domain resource interval, that is, the frequency domain resource interval ΔF1 = 12 (subcarriers); the frequency domain starting position of the target signal is F offset1 =0 (the frequency domain offset relative to the starting subcarrier of the RB where it is located is 0 subcarriers).
[0536] First time domain resource interval or first transmission period ΔT1=1 (slot);
[0537] Second time domain resource interval or second transmission period ΔT2=80 (slots);
[0538] The starting position T of the first time domain resource set offset1 =1(OFDM symbol), T offset1 It refers to the starting symbol in the first time domain resource set relative to the first time domain interval T p or refers to the offset of the starting symbol in the first time domain resource set relative to slot0;
[0539] The starting position T of the second time domain resource set offset2 =1(OFDM symbol), T offset2 Refers to the starting symbol in the second time domain resource set relative to the first time domain interval T p or refers to the offset of the starting symbol in the second time domain resource set relative to slot0;
[0540] The starting position of the common time domain resource unit T offset3 = 0 (OFDM symbols), T offset3 Refers to the offset of the starting position of the common time domain resource unit relative to the starting position of the first time domain resource set;
[0541] The number of continuous time domain resource units in the first time domain resource set is l1=6;
[0542] The first time domain interval T p The number of non-contiguous time domain resource units l2=80;
[0543] The first time domain interval T p The number of the first time domain resource sets n1=1.
[0544] You can configure 6 signal resources as target signals, for example Figure 9As shown. Among them:
[0545] The time domain sending period of resource#0 is ΔT1, and the time domain sending period of resources#1 to 5 is ΔT2;
[0546] The bandwidth of resource #0 to resource #5 is configured as 273 RBs, and the frequency domain density is 1 (one subcarrier out of the 12 subcarriers in each RB is used to carry the target signal).
[0547] Part of resource#0 (the part in the same time slot as resource#1-5) and resource#1-5 are used as the first time domain resource set, and resource#0 is used as the second time domain resource set;
[0548] The starting time domain positions of resource#0~5 are T offset =1, T offset =2, T offset =3, T offset =4, T offset =5 (OFDM symbols), where T offset Indicates the time domain offset of each resource relative to slot 0.
[0549] In this case, the measurement configuration information needs to indicate a method for jointly performing sensing measurements on the multiple signal resources, including indicating a specific measurement quantity and resource identifiers for the joint measurement. Furthermore, the method further includes at least one of the following: performing measurements based on resource #0 and a portion of resource #0 (the portion in the same slot as resource #1 to 5) plus resource #1 to 5 to obtain a measurement result; performing measurements based on resource #0 and resource #1 to 5 to obtain a measurement result; or performing measurements based on resource #0 and resource #1 to 5 simultaneously to obtain a measurement result.
[0550] Example 3:
[0551] This embodiment illustrates a time-domain and frequency-domain resource mapping solution for multi-port multiplexing target signals.
[0552] The target signal can be configured to be sent on multiple ports, with the target signal resource patterns on different ports being time-division multiplexed, or the resource patterns on different ports being frequency-division multiplexed, for example Figure 10 As shown, multi-port signals are transmitted in the frequency domain by interleaving and mapping. The time domain resource parameters of the signals corresponding to different ports are the same, and the frequency domain starting positions in the frequency domain resource parameters are different and associated with the port index.
[0553] When the resource patterns on different ports are the same (i.e., the time-frequency domain resources used to carry the target signal are the same):
[0554] The target signals on different ports are generated using the same sequence and are mapped to the same time-frequency domain resources by multiplying different orthogonal cover codes (OCCs). For example, for a two-port frequency-domain OCC, the OCC sequence used by port 0 is [+1 +1], and that used by port 1 is [+1 -1]. On the same frequency-domain resource, the signal sequence corresponding to port 0 is {r(0), r(1), r(2), r(3), ...}, and the signal sequence corresponding to port 1 is {r(0), -r(1), r(2), -r(3), ...}.
[0555] Alternatively, target signals on different ports are generated in different sequences and are directly mapped to the same time-frequency domain resources.
[0556] The signal sequence generation method of each port may be at least one of the following:
[0557] Based on pseudo-random sequence (PN) generation;
[0558] Generation based on the ZC (Zadoff-Chu) sequence (or the cyclic extension sequence of the ZC sequence, or the truncated sequence of the ZC sequence);
[0559] Based on Chirp signal generation.
[0560] When different port signals are generated using different sequences, the following sequence generation methods can be used:
[0561] If the sequence is generated based on a PN sequence (for example, by performing quadrature phase shift keying (QPSK) modulation), an initial value of the PN sequence, a primitive polynomial of the PN sequence, a cyclic shift value of the PN sequence, or a truncation position of the PN sequence (i.e., the sequence may be generated by obtaining an entire sequence based on a system bandwidth and then truncation based on an actual bandwidth)) is associated with the first information;
[0562] If the sequence is generated based on a ZC sequence, a root sequence number or a cyclic shift value of the ZC sequence is associated with the first information;
[0563] If the sequence is generated based on a Chirp signal, the frequency modulation slope or the starting frequency of the Chirp signal is associated with the first information.
[0564] The first information includes at least one of the following:
[0565] Perception area identification;
[0566] Whether it is used for perception identification, perception service identification, or perception service type identification;
[0567] Perception target identification, the tag identification associated with the perception target;
[0568] Number of perceived targets;
[0569] Perceptual measurement quantity identification;
[0570] The device identifier involved in the sensing measurement may be, for example, a cell identifier or a terminal identifier, such as a Radio Network Temporary Identifier (RNTI);
[0571] Time domain or frequency domain resource information;
[0572] port index;
[0573] Code Division Multiplexing (CDM) group index;
[0574] Number of ports;
[0575] Number of CDM groups;
[0576] Antenna index, or antenna group index / subarray index / antenna panel index;
[0577] Maximum number of antennas, or number of antenna groups / subarrays / antenna panels;
[0578] Codeword index.
[0579] The above time domain or frequency domain resource information includes at least one of the following:
[0580] Information related to time domain resources and frequency domain resources;
[0581] The above-mentioned time domain resource-related information may include at least one of the following: radio frame index, subframe index, slot index, symbol index, duration, time domain density, CP type, CP length, and may also be a coherent processing time window index or the number of coherent processing time windows; the line frame index, subframe index, time slot index, and symbol index may be at least one of the following:
[0582] Radio frame index and subframe index defined by the communication system;
[0583] Perceive the relative radio frame index and subframe index within the coherent processing time window / perceive the relative radio frame index and subframe index within the resource block;

[0585] Coherent processing time window / symbol index within the perceived resource block;
[0586] A timeslot index within a radio frame;
[0587] Coherent processing time window / slot index within the sensing resource block;
[0588] The above-mentioned coherent processing time window, i.e., the time window for calculating and outputting the perception measurement result each time (for example, the time domain resource length corresponding to the range-Doppler map obtained by performing a two-dimensional FFT operation), may include multiple time slots / symbols.
[0589] The frequency domain resource-related information may include at least one of the following: RE index, RB index, frequency point information, frequency band information, bandwidth, frequency domain density, and subcarrier spacing;
[0590] A perception resource block index can also be introduced, where the perception resource block contains multiple PRBs and multiple time slots / symbols, that is, it contains specific time-frequency domain resources (for example, a two-dimensional FFT operation is performed to obtain the frequency domain resource length and time domain resource length corresponding to the range-Doppler map).
[0591] Further explanation of the first information and sequence generation is as follows:
[0592] For perception region identification:
[0593] The sensing area is the target area to be sensed, which can be divided in advance and includes:
[0594] Multiple base station coverage areas (cells) form a perception area, associated with a perception area identifier n areaID ,like Figure 11 As shown, each hexagonal area represents a base station coverage area, and areas of the same color represent the same sensing area. In particular, RNA (RAN-based notification area) can be used as a sensing area, and RNA ID can be used as the sensing area identifier.
[0595] The coverage area (cell) of a single base station contains multiple sensing areas, which are associated with multiple sensing area identifiers. For example, with the base station as the origin, its coverage area is rasterized and divided into multiple sensing areas, and each area is associated with an area ID recorded as n. areaID ,like Figure 12 ,The red dotted line represents the base station coverage area, and each square represents the divided sensing area.
[0596] Alternatively, the area ID n may be generated by directly using a geographical area identifier such as longitude and latitude or coordinates that is not related to the base station location. areaID .
[0597] It can also be that different angle ranges relative to the base station are associated with different area IDs n areaID For example, the azimuth angle x1°~x2° and the pitch angle y1°~y2° correspond to the sensing area ID1.
[0598] The identification of whether it is used for perception, or the identification of a specific perception service, or the identification of the type of perception service, or the identification of the perception measurement quantity are described as follows:
[0599] Based on whether it is used for perception, or a specific perception service identifier, or a perception service type identifier, it is generated, including:
[0600] Based on whether it is used for perception, when it is not used for perception, n sensingID =0; when used for perception n sensingID =1.
[0601] Based on the specific perception service identifier, for example, different perception services correspond to different perception service ID n sensingID , wherein, the perception service refers to the corresponding description of the above embodiment and is not described here in detail.
[0602] It can also be the identification of the perception service type. Different categories correspond to different perception service IDs n sensingID , for example, the perception functions or business types are divided according to the scope and scale, for example:
[0603] Category 1 (close distance / small range): material analysis, component analysis, gesture recognition, lip reading recognition, gait recognition, expression recognition, facial recognition, respiratory monitoring, heart rate monitoring, pulse monitoring, etc.
[0604] Category 2 (medium distance / medium range): intrusion detection, population counting, indoor positioning, etc.
[0605] Category 3 (long distance / large range): humidity / brightness / temperature / atmospheric pressure monitoring, air quality monitoring, weather condition monitoring, environmental reconstruction, topography, building / vegetation distribution detection, pedestrian or vehicle flow detection, etc.
[0606] Other classification standards can also be used, such as classification based on function into positioning perception, imaging perception, pattern recognition perception, etc.; classification based on power consumption / energy consumption, classification based on resource occupancy, etc.
[0607] Alternatively, the perception signal may be generated according to the measurement quantity identifier, that is, at least one of the perception measurement quantities is associated with a measurement quantity identifier, for example, as shown in Table 2 below:
[0608] Table 2:
[0609]
[0610]
[0611] The perception measurement amount refers to the corresponding description of the above embodiment and is not described here in detail.
[0612] The description of the perception target identifier (or the tag identifier associated with the perception target) is as follows:
[0613] Based on the perception target identifier (or the tag identifier associated with the perception target), including:
[0614] The signal sending device obtains the identification of the sensing target. Different sensing targets correspond to different sensing target IDn. targetID , where the determination of the perception target can be based on prior information obtained from existing measurement results. For example, base station A sends a perception measurement signal through an omnidirectional beam to perform preliminary measurement, base station A obtains a range-Doppler map (or a range-angle map, etc.), determines the number of targets based on the range-Doppler map, and assigns an ID to each target. Alternatively, base station A sends a perception measurement signal through an omnidirectional beam to perform preliminary measurement, and a receiving device (such as another base station or terminal) obtains a range-Doppler map (or a range-angle map, etc.), determines the number of targets based on the range-Doppler map, assigns an ID to each target, and then notifies the sending base station of the target ID or target-related information.
[0615] After the signal sending device determines the ID of each target, it generates signals for sensing different targets according to different target IDs. These sensing signals are sent using different beams, with the beam direction pointing to the sensing target associated with the target ID.
[0616] The sensing target is equipped with a tag, and different tags are associated with different tag IDs. The transmitting device obtains the corresponding target's tag ID and generates signals used to sense different targets. The tag can be a device that supports backscatter communication, and its excitation source can be a device other than the tag, or the tag itself. It can also be a UE, meaning that the sensing target is equipped with a standard transceiver module, such as a communication device such as an in-vehicle terminal installed in a car.
[0617] It can also be the identification of the perception target type. Different types correspond to different perception target IDs. For example, they are divided into stationary targets and moving targets. The latter can be further divided into high-speed targets and low-speed targets. Different types of targets correspond to different n sensingID .
[0618] Specifically, the perception area is identified by n areaID For example, the initial value of the PN sequence can be:
[0619] c init =n areaID, where n areaID It is the perception area identifier.
[0620]
[0621] or or
[0622] in, is the number of symbols in each time slot, is the time slot index in the radio frame, l is the symbol index in the time slot, n areaID is the perception area identifier, x is a non-negative positive integer.
[0623] Among them, the coefficient parameter of the first term in the initialization formula can be determined according to the variable value range and the value of the coefficient parameter of the following terms. For example, if there are 1000 perception area IDs in total and they need to be represented by 10-bit binary numbers, then x=10 can be set to ensure that no repeated generation sequence occurs. Where A is a non-negative positive integer, and A=31 can be set.
[0624] or
[0625] in is the physical cell identifier, or or Where x and y are non-negative positive integers. init =(2 x n RNTI +n areaID )mod2 A or c init =2 x n RNTI +n areaID , where n RNTI is the terminal identifier, where x and A are non-negative positive integers, and A can be set to 31.
[0626] or It can also be or Where x, y, and A are non-negative positive integers, and A can be set to 31.
[0627] or Where q is the codeword index, which can also be or Where x, y, z, and A are non-negative positive integers, and A can be set to 31.
[0628] Alternatively, taking the sensing area identifier and the sensing target identifier as an example, the initial value of the PN sequence may be:
[0629] or
[0630] Or, with port index n port For example, the initial value of the PN sequence can be:
[0631] or or or
[0632] Where x, y, z, and A are non-negative positive integers, so A=31, n port is the port index, is the physical cell identifier, is the number of symbols in each time slot, is the time slot index in the radio frame, l is the symbol index in the time slot, n period is the coherent processing time window index. It should be noted that the symbol index l and the time slot index It can be the symbol index and time slot index corresponding to a symbol in a certain perceptual coherent processing time window.
[0633] Alternatively, the perceptual coherence processing time window index n period and port index n port For example, the initial value of the PN sequence can be:
[0634] c init =(2 x (n period +1)+n port )mod2 A or c init =2 x (n period +1)+n port
[0635] or or or or
[0636] in, represents the number of time slots corresponding to each coherent processing time window, The time slot index within the coherent processing time window.
[0637] The signal sequence may also be generated based on a ZC sequence. The perception signal generated in this manner has a smaller peak-to-average power ratio (PAPR) than a perception signal generated based on a PN sequence, has higher power amplifier efficiency, and is beneficial to improving perception measurement coverage performance. The root sequence number value or cyclic shift value of the ZC sequence is associated with the first information. Specifically, the generation method is:
[0638] Determined by the root sequence number q Then we get the base sequence 0≤n<M,N ZC is the largest prime number less than the sequence length M, and the perception signal can also be obtained by cyclic shift:
[0639] The sequence length M is related to the perception signal resource and the sequence length. For example, the number of frequency domain resource units used to transmit the perception signal, that is, the sequence length, is determined according to the perception signal bandwidth and the frequency domain resource interval.
[0640] Among them, the cyclic shift value α and the root sequence number q are associated with the first information, and the association method can be, for example, the perception area identifier is an 8-bit ID, then all or part of the 8 bits can be used to calculate the root sequence number q or cyclic shift value α of the sequence, for example, the cyclic shift value α can be determined by the first 4 bits of the ID, and the root sequence number q is determined by the last 4 bits of the ID; for another example, the cyclic shift value α is determined according to the perception service identifier, and the root sequence number q is determined according to the perception area identifier. There may be a preset mapping relationship between different perception area identifiers and the root sequence number q, for example, as shown in Table 3 below, and the preset mapping relationship is agreed upon or obtained through a signaling message.
[0641] Table 3:
[0642] Sensing area ID Root serial number q ID1 X1 ID2 X2 … …
[0643] It can also be calculated according to a formula. Specifically, the root sequence number q can be calculated, for example:
[0644]
[0645]
[0646] Among them, u∈{0, 1, ..., 29} is the group number, v is the base sequence number in the group, and taking the perception area identifier as an example, the value can be u=(n areaID )mod30,v=0.
[0647] The cyclic shift value may be calculated, for example, as: is the maximum value in the region identifier.
[0648] Alternatively, a signal sequence may be generated based on a Chirp or FMCW signal, wherein the frequency modulation slope of the Chirp or FMCW signal is associated with the first information. FMCW transmits a waveform whose frequency changes with time, usually linearly. A frequency modulation cycle of an FMCW waveform is generally also called a Chirp, such as Figure 13 shown.
[0649] Chirp signal can be expressed by the following formula:
[0650]
[0651] Among them, A0 is the amplitude, f c is the starting frequency, |k|=±B / T is the frequency modulation slope, where B is the bandwidth and T is the chirp duration (i.e., the frequency modulation period of FMCW).
[0652] Among them, different frequency modulation slopes are associated with the first information. For example, different perception services have different requirements for bandwidth and Chirp duration, that is, different frequency modulation slope requirements. There may be a preset mapping relationship between different perception service IDs and different frequency modulation slopes.
[0653] Different starting frequencies are associated with the first information. For example, there is a preset mapping relationship between different perception areas and starting frequencies.
[0654] Example 4:
[0655] This embodiment mainly describes the perception measurement calculation.
[0656] This embodiment describes a process of obtaining measurement results based on a first time domain (or frequency domain) resource set and a second time domain (or frequency domain) resource set. The measurement quantity in this embodiment is Doppler.
[0657] The measurement based on the first time domain resource set may be performed by calculating the composite frequency offset value f under the current channel environment based on the first time domain resource set. Δ For example, LS channel estimation is performed on the received target signal to obtain channel information, and then the composite frequency deviation value is calculated based on the phase difference and interval duration between the channel information corresponding to different OFDM symbols in the first time domain resource set; the above-mentioned measurement based on the second time domain resource set can be, for example, performing LS channel estimation on the received target signal to obtain channel information, and performing FFT calculation in the time domain dimension to obtain Doppler spectrum information based on the channel information corresponding to the second time domain resource set.
[0658] Since the resource time domain interval corresponding to the first time domain resource set is small, we can use f ΔThe Doppler range in the current channel environment is determined, and then the Doppler spectrum obtained by measuring based on the second time domain resource set is corrected based on the Doppler range, thereby solving the Doppler measurement ambiguity problem.
[0659] Doppler calculation in perception measurement usually uses algorithms such as FFT or Multiple Signal Classification (MUSIC), Estimation of Signal Parameters via Rotational inVariance Technique (ESPRIT), etc. However, due to the limitation of signal resource configuration, the observable Doppler range is limited, that is, satisfying |f dmax |≤1 / 2ΔT, the Doppler observation window length is ΔT is the signal time domain resource interval, and the corresponding Doppler observation window is (window 0), such as Figure 14 When the target Doppler exceeds When it falls in other Doppler observation windows, Doppler measurement ambiguity occurs. For example, the target Doppler (first Doppler) measured according to the second time domain resource set is Calculated based on the first time domain resource set This indicates that the actual target Doppler is located in window 1, so the final actual target Doppler value (second Doppler) is (Shift one observation window). It should be noted that if there are multiple targets, in order to ensure measurement performance, the maximum Doppler difference of multiple targets should be less than the Doppler observation window length. That is, the Doppler values of multiple targets are located in the same observation window.
[0660] Assume that there is a moving target in the environment. Under the ideal signal configuration, that is, the first time domain interval T p All symbols in the channel are used to send the target signal. At this time, the receiving end performs LS channel estimation on the received target signal to obtain channel information, and then performs FFT calculation in the time domain to obtain Doppler spectrum information as follows: Figure 15 shown.
[0661] For example, in Example 1 ( Figure 8 ) as an example, the target signal configuration is performed, assuming that the subcarrier spacing of the OFDM system is 30kHz and the length of each time slot is 0.5ms, that is, the first time domain resource interval or the first transmission period ΔT1 = 0.5ms. LS channel estimation is performed on the received target signal to obtain channel information. Based on the channel information corresponding to the second time domain resource set, the FFT calculation in the time domain dimension is performed to obtain the Doppler spectrum information. The corresponding maximum unambiguous Doppler measurement range is That is -1000Hz~1000Hz. At this time, the Doppler spectrum information obtained by measuring according to the second time domain resource set is as follows Figure 16 As shown in FIG. 1 , the first Doppler value is −925 Hz. Since the maximum unambiguous Doppler measurement range is exceeded, it is necessary to perform measurement based on the first time domain resource set and eliminate Doppler ambiguity.
[0662] According to the phase difference between symbols 1 and 2, the phase difference between symbols 3 and 4, and the phase difference between symbols 5 and 6 in the first time domain resource set, the composite frequency offset value is calculated and averaged to obtain: Δ =1098Hz. According to the Doppler results obtained by the second time domain resource set, it can be determined that the number of targets in the environment is 1. It can be seen that the Doppler frequency shift range of the target should be That is, the Doppler spectrum measured by the second time domain resource set should be moved to window 1 (1000 Hz to 2000 Hz), such as Figure 17 As shown in FIG, the target Doppler value (second Doppler) after removing the Doppler ambiguity is determined to be 1075 Hz, which is consistent with the Doppler result calculated under the ideal signal configuration.
[0663] It should be noted that the calculation of the composite frequency offset value here is only an example, and the specific method of calculating the Doppler (or composite frequency offset value) based on the first time domain resource set is not limited in this embodiment of the application.
[0664] Assume that there are three moving targets in the environment. Under the ideal signal configuration, that is, the first time domain interval T p All symbols in the channel are used to send the target signal. At this time, the receiving end performs LS channel estimation on the received target signal to obtain channel information, and then performs FFT calculation in the time domain to obtain Doppler spectrum information as follows: Figure 18 shown.
[0665] Similarly, in Example 1 ( Figure 8 ) as an example, target signal configuration is performed. At this time, the Doppler spectrum information obtained by measuring the second time domain resource set is as follows: Figure 19 As shown in FIG. 1 , the first Doppler value is −925 Hz. Since the maximum unambiguous Doppler measurement range is exceeded, it is necessary to perform measurement based on the first time domain resource set and eliminate Doppler ambiguity.
[0666] Similarly, based on the phase difference between symbols 1 and 2, the phase difference between symbols 3 and 4, and the phase difference between symbols 5 and 6 in the first time domain resource set, the composite frequency offset value is calculated and averaged to obtain: Δ=1199Hz. Based on the Doppler results measured by the second time domain resource set, it can be determined that the number of targets in the environment is 3. The Doppler difference caused by the movement of the three targets is less than 2000Hz, that is, the Doppler frequency shifts of the three targets are in the same Doppler observation window, that is, the Doppler frequency shift range of the three targets should be That is, the Doppler spectrum measured by the second time domain resource set should be moved to window 1 (1000 Hz to 2000 Hz), such as Figure 20 As shown in FIG, the target Doppler values (second Doppler) after removing the Doppler ambiguity are determined to be 1075 Hz, 1050 Hz, and 1200 Hz, which are consistent with the Doppler results calculated under the ideal signal configuration.
[0667] The measurement result obtained by measuring based on the first time domain resource set is the composite frequency offset value f Δ , the measurement result obtained by measuring based on the second time domain resource set is the first Doppler, and the measurement result obtained by jointly measuring based on the first time domain resource set and the second time domain resource set is the second Doppler. It should be noted that the method based on the joint measurement of the first time domain resource set and the second time domain resource set given in this embodiment is only an example, and the specific calculation method is not limited by this patent. It can also be, for example, based on all signal resources based on the first time domain resource set and the second time domain resource set to obtain channel information, and then obtain the second Doppler through time domain non-uniform FFT operation. Among them, the measurement results obtained by measuring based on the first time domain resource set and the measurement results obtained by measuring based on the second time domain resource set can be reported separately or jointly.
[0668] Based on the target Doppler value, the target radial velocity can be calculated. The measurement result can also be a time delay. When the target signal frequency domain resource pattern meets the characteristics, the calculation process of the time delay information is similar to the Doppler calculation in this embodiment, and the target distance information can also be further calculated.
[0669] In addition, in addition to the measured delay / distance and Doppler / velocity information, the above measurement results can also be angle information, or perception information further calculated based on the above measurement results, including but not limited to: direction, spatial position, acceleration, target presence, trajectory, movement, expression, vital signs, quantity, imaging results, weather, air quality, shape, material, composition information, etc.

[0691] The above-mentioned interference or noise power includes the sum of interference power and noise power, interference power or noise power.
[0692] The total received power of the first device on the target resource may include the received power of signals of the serving cell and the non-serving cell on the target resource, adjacent channel interference power, and thermal noise power. The total received power may also be a linear average (in W) of the total received power of the first device on the target resource.
[0693] The power corresponding to the received signal strength indication (RSSI) of the first device on the first resource may be total received power = RSSI*K1, where K1 is a coefficient and may be a protocol agreement or a network-side configuration. In some embodiments, the power corresponding to the RSSI may also be RSSI, i.e., total received power = RSSI.
[0694] The target signal received power refers to the reference signal received power (RSRP) of the target signal.

It should be noted that, when at least one of the fifth, sixth, seventh, and eighth indicators is included, the perception-related indicators in the embodiments of the present application may include or exclude the first, second, third, and fourth indicators.
[0709] The above target coefficient can be expressed as K2, such as the eighth indicator = K2*first indicator / total received power, K2 is a coefficient, and K2 can be specifically agreed upon in the protocol or configured on the network side.
[0710] In this implementation, by using the fifth indicator, the sixth indicator, the seventh indicator or the eighth indicator, it is possible to take the received power and the interference or noise into consideration when determining the measurement switching, so that the measurement switching is more reliable.

[0713] In some embodiments, the path associated with the sensory target satisfies at least one of the following:
[0714] The parameter meets the first preset threshold, or the parameter is within the first preset range;
[0715] The parameters meet the preset modulation rules;
[0716] The parameter difference with the first arrival path meets the second preset threshold, or the parameter difference with the first arrival path is within a second preset range;
[0717] The parameter difference with the reference path meets a third preset threshold, or the parameter difference with the reference path is within a third preset interval.
[0718] The above parameters may include at least one of the following:

The above-mentioned parameter satisfying the first preset threshold may mean that the parameter exceeds or is equal to the first preset threshold, the above-mentioned parameter difference with the first-reaching path satisfies the second preset threshold may mean that the parameter difference with the first-reaching path exceeds or is equal to the second preset threshold, and the above-mentioned parameter difference with the reference path satisfies the third preset threshold may mean that the parameter difference with the reference path exceeds or is equal to the third preset threshold.
[0723] For example: if the perception service is moving target detection, it is necessary to detect the path with Doppler greater than zero as the path associated with the perception target; or for the traffic scene perception target is a car, the default vehicle speed is 40km / h to 120km / h, then the path within the corresponding speed range (Doppler range) is detected as the path associated with the perception target; or the distance between the perception target area and the perception signal transceiver needs to meet specific requirements, then the path within the corresponding time delay range is detected as the path associated with the perception target; or if the perception service is respiratory monitoring, the corresponding normal respiratory rate can be judged according to the person's gender and age (for example, 15 to 30 times / minute can be used as perception prior information, and the corresponding Doppler range can be calculated, 0.25 to 0.5Hz).
[0724] The first arrival path can be a line-of-sight (LOS) path, specifically the path of the target signal that first reaches the receiver. The reference path can be a path reflected by a known target, such as a reconfigurable intelligence surface (RIS), backscatter, or other known passive targets.
[0725] The preset modulation rule may be a protocol agreement or a network configuration. The specific modulation rule is a modulation rule of a tag or backscatter device or RIS, that is, the path associated with the sensing target may be a path modulated and reflected by the tag or backscatter device or RIS.
[0726] In one of the above optional implementations, the path associated with the perceived target can be determined in multiple ways, which can not only improve the flexibility of determining the path associated with the perceived target, but also improve the accuracy of determining the path associated with the perceived target based on multiple ways.
[0727] In some embodiments, before determining the path associated with the sensing target, a path set may be determined, the path set including paths whose amplitude, power, intensity or energy exceeds a certain threshold, such as Figure 21 As shown, the path set includes paths 0, 1, 2, and 3. Then, the path associated with the perceived target is determined in the path set based on the at least one item mentioned above, so as to reduce the amount of calculation.
[0728] The following example illustrates the calculation of indicators in the embodiment of the present application through an example. It should be noted that the calculation of each indicator in the embodiment of the present application is not limited, and the following example is only an example.
[0729] The calculation method 1 of the first indicator is as follows:
[0730] The first device (such as a terminal) performs channel estimation based on the transmitted target signal X(k) and the received signal Y(k) corresponding to the target signal to obtain a channel response (Channel Response) H(k) = Y(k) / X(k), where k = 0, 1, 2, ..., K-1 represents the resource unit index, and K is the number of resource units. After the first device obtains the channel response H(k), it transforms it into a first dimension and determines the path associated with the perception target in the first dimension. The power of the path associated with the perception target is then calculated as the first indicator. If the path associated with the perception target includes multiple paths, the sum of the powers of the multiple paths is calculated as the first indicator.
[0731] The first dimension includes one of the following:
[0732] Delay dimension;
[0733] Doplevi;
[0734] Azimuth dimension;
[0735] Pitch angle dimension;
[0736] A dimension that is a combination of at least two of the delay dimension, Doppler dimension, azimuth dimension, and elevation dimension. For example, the delay-Doppler dimension, the delay-Doppler-angle dimension, etc.
[0737] For example, H(f) is the channel response, where f=0, 1, 2, ..., N-1 represents the frequency domain sampling point (e.g., subcarrier index), and H(f) can be transformed into the delay dimension (first dimension) by performing an inverse Fourier transform on it. For another example, H(f, t) is the channel response, where f=0, 1, 2, ..., N-1 represents the frequency domain sampling point (e.g., subcarrier index), and t=0, 1, 2, ..., M-1 represents the time domain sampling point (e.g., OFDM symbol index), and H(f, t) can be transformed into the time domain dimension by performing an inverse Fourier transform along the frequency domain dimension and a Fourier transform along the time domain dimension. Delay-Doppler dimension (first dimension); for another example, H(f, t, s) is the channel response, where f=0, 1, 2, ..., N-1 represents the frequency domain sampling point (e.g., subcarrier index), t=0, 1, 2, ..., M-1 represents the time domain sampling point (e.g., OFDM symbol index), s=0, 1, 2, ..., P-1 represents the spatial domain sampling point (antenna index or port index), then H(f, t, s) can be transformed into the delay-Doppler-angle dimension (first dimension) by performing an inverse Fourier transform along the frequency domain dimension, a Fourier transform along the time domain dimension, and a Fourier transform along the antenna domain dimension.
[0738] Method for determining the path associated with the perception target (referred to as the perception path) in the channel response obtained by measuring the target signal:
[0739] Determine a path set. The paths in the path set include the paths whose amplitude, power, intensity or energy exceeds a certain threshold among all the paths after the channel response is transformed into the first dimension. For example Figure 21 In the example, paths 0, 1, 2, and 3 are the paths in the path set. The threshold can be set to be above the noise threshold or above the noise interference threshold, or as agreed upon in the protocol. This step (determining the path set) is optional, and the path associated with the perceived target can be determined only in the next step.
[0740] A path that satisfies a first condition is selected from the path set or from all paths of the target signal as the path associated with the perceived target. The first condition includes at least one of the following:
[0741] The amplitude, power, intensity or energy of the path exceeds the preset threshold or is within the preset range, such as the preset threshold is 5 times the noise threshold;
[0742] The Doppler of the path exceeds the preset threshold or is within the preset range;
[0743] The path delay exceeds the preset threshold or is within the preset range;
[0744] The angle of the path exceeds the preset threshold or is within the preset range;
[0745] The difference between the amplitude / power / intensity / energy of the path and the first-reach path (e.g., LOS path) or the reference path exceeds a preset threshold or is within a preset range. The reference path may be a path reflected by a known target (e.g., RIS / Backscatter / other known passive targets, etc.);
[0746] The Doppler difference between the path and the first arrival path (such as the LOS path) or the reference path exceeds a preset threshold or is within a preset range;
[0747] The delay difference between the first arrival path (such as the LOS path) or the reference path exceeds the preset threshold or is within the preset range;
[0748] The angle difference between the first arrival path (e.g., LOS path) or the reference path exceeds a preset threshold or is within a preset range;
[0749] The amplitude, power, intensity, energy or phase of the path meets the specific modulation rule. The specific modulation rule is the modulation rule of the tag / backscatter device or RIS. That is, the path associated with the perceived target can be the path modulated and reflected by the tag / backscatter device or RIS.
[0750] The above-mentioned first conditions may also be based on statistical results over a period of time; for example, the ratio of the above-mentioned indicators (such as the Doppler of the path, the time delay of the path, etc.) exceeding a preset threshold or being within a preset range in a preset time window reaches a preset ratio, or the number of times the above-mentioned indicators (such as the Doppler of the path, the time delay of the path, etc.) exceed a preset threshold or are within a preset range in a preset time window reaches a preset number of times;
[0751] The preset threshold or preset interval is sent by another device to the receiving device and is determined by the other device based on prior perception information or perception requirements. Alternatively, the preset threshold or preset interval may be a protocol agreement, or the preset threshold or preset interval is determined by the receiving device based on prior perception information or perception requirements.
[0752] The priori perception information or perception requirements include the following information:
[0753] Perception services or perception service types, such as detecting the presence of a target, positioning, speed detection, distance detection, angle detection, acceleration detection, material analysis, component analysis, shape detection, classification, radar cross section RCS (Radar Cross Section, RCS) detection, polarization scattering characteristic detection, fall detection, intrusion detection, population statistics, indoor positioning, gesture recognition, lip reading recognition, gait recognition, expression recognition, facial recognition, respiration monitoring, heart rate monitoring, pulse monitoring, humidity / brightness / temperature / atmospheric pressure monitoring, air quality monitoring, weather condition monitoring, environmental reconstruction, topography, building / vegetation distribution detection, pedestrian or vehicle flow detection, crowd density, vehicle density detection, etc.; the perception service type can be to classify multiple different perception services according to certain characteristics, for example, according to function, it can be divided into detection-type perception services (for example, including intrusion detection, fall detection), parameter estimation-type perception services (distance, angle, speed calculation), recognition-type perception services (motion recognition, identity recognition), etc., and can also be divided according to the range of perception (close-range perception, medium-range perception, long-range perception), according to the degree of perception fineness (coarse-grained perception, fine force perception, etc.), according to power consumption / energy consumption, according to resource occupancy, etc. If the sensing service is respiratory monitoring, the corresponding normal respiratory rate can be determined based on the person's gender and age (for example, male: 13-21 breaths / minute, female: 15-20 breaths / minute; adult: 12-20 breaths / minute, child: approximately 30-40 breaths / minute), which can be used as perception prior information;
[0754] Perception target area: refers to the location area of the perception object, or the location area where imaging or environmental reconstruction is required; for example, the preset interval range of the time delay of the path associated with the perception target is determined based on the approximate location / distance of the perception object;
[0755] Perception object type: Classifies the perception object according to its possible motion characteristics. Each perception object type contains information such as the typical perception object's motion speed range, motion acceleration range, and typical RCS range.
[0756] The number of perceived targets; for example, the camera perception result is used as a perception prior information to obtain the number of perceived targets.
[0757] For example Figure 21 In the figure, paths 0, 1, 2, and 3 are the paths in the path set, where paths 2 and 3 are the perception paths that meet the first condition (for example, their delays meet the preset threshold), and paths 0 and 1 are the paths associated with other scatterers.
[0758] in, Figure 21, a multipath diagram of the channel response in the first dimension (delay dimension, Doppler dimension, azimuth dimension, or elevation angle dimension), where the horizontal axis is the first dimension and the vertical axis is the normalized amplitude, power, intensity or energy.
[0759] For frequency range 1, the reference point for the first metric can be the antenna connector of a receiving device, such as a terminal. For frequency range 1, if the receiving device has multiple receiving channels, the first metric measured and reported by the receiving device cannot be lower than the metric of any single receiving channel. For frequency range 2, the first metric measured for a receiving channel must be obtained by measuring the combined signals of the multiple antenna elements corresponding to that receiving channel.
[0760] The calculation method 2 of the first indicator can be as follows:
[0761] When calculating the received power of the path associated with the sensing target, it can also be the power of the path associated with the sensing target in the first dimension and The difference between is taken as the first indicator, where N1 represents the number of paths associated with the perceived target. is the average power of multiple paths outside the path set in the first dimension.
[0762] The calculation method 1 of the received power of the target signal can be as follows:
[0763] The received power of the target signal may be obtained by the receiving device, after obtaining the channel response (Channel Response) H(k), transforming it into the first dimension, determining a path set in the first dimension, and then calculating the power sum of all paths in the path set.
[0764] The calculation method 2 of the received power of the target signal can be as follows:
[0765] The received power of the target signal can also be the sum of the powers of all paths in the path set in the first dimension and , where N2 represents the number of paths in the path set.
[0766] The total received power is calculated as follows:
[0767] Total received power
[0768] Wherein, Y(k) is the received signal corresponding to the target signal, k=0, 1, 2, ..., K-1 represents the resource unit index, and K is the number of resource units.
[0769] The second indicator can be calculated as follows:
[0770] The channel response H(k) is processed by the first filter to obtain H filter1 (k), then according to H filter1 (k) and the target signal X(k) are used to calculate the received signal Y after the first filtering process filter1 (k), that is, Y filter1 (k)=H filter1 (k)X(k). Then the received signal Y(k) is subtracted from the received signal Y after the first filtering process. filter1 (k) Thus we get the interference and noise signal Y σ1 (k), that is, Y σ1 (k) = Y(k) - Y filter1 (k), and then calculate the second indicator:
[0771]
[0772] The first filtering process is used to eliminate the noise and interference in the first dimension and the path associated with the non-perceived target. For example, the first filtering process Figure 21 The amplitude, power, intensity or energy of other paths except the path associated with the perception target are set to zero. The channel response H after the first filtering process filter1 (k) does not include noise, interference, or paths associated with non-perceived targets, but only includes paths associated with perceived targets.
[0773] The calculation method 1 of the third indicator can be as follows:
[0774] The channel response H(k) is processed by the second filter to obtain H filter2 (k), then according to H filter2 (k) and the target signal X(k) are used to calculate the received signal Y after the second filtering process filter2 (k), that is, Y filter2 (k)=H filter2 (k)X(k). Then the received signal Y(k) is subtracted from the received signal Y after the second filtering process. filter2 (k) Thus we get the interference and noise signal Y σ2 (k), that is, Y σ2 (k) = Y(k) - Y filter2 (k), and then calculate the third indicator:
[0775]
[0776] The second filtering process can be a noise interference suppression process on the first dimension (for example Figure 21The amplitude, power, intensity or energy of the other paths except the path set is set to zero), or minimum mean square error (MMSE) filtering. The channel response after the second filtering process H filter2 (k) does not contain noise and interference, but only contains the paths in the path set.
[0777] The calculation method 2 of the third indicator can be as follows:
[0778] According to the average power of multiple paths outside the path set in the first dimension Calculate the third index P σ2 ,Right now Where N represents the number of sampling points in the first dimension.
[0779] It should be noted that if the receiving device determines that there are multiple sensing targets, or the receiving device obtains the number of sensing targets based on prior sensing information or sensing requirements, the following methods are available:
[0780] Method 1: Calculate the perception-related index (also called target index) of each perception target separately. Figure 21 The path associated with each perception target is determined separately, and then the perception-related indicators corresponding to each perception target are calculated separately. At this time, when calculating the second indicator corresponding to a perception target (such as perception target A), there are two methods: the second indicator of perception target A = total received power - the first indicator of perception target A; or the second indicator of perception target A = total received power - the first indicator of perception target A - the first indicator of perception target B; (assuming there are two perception targets: A and B); similarly, there are two ways to calculate the fourth indicator: the fourth indicator of perception target A = RSRP of target signal - the first indicator of perception target A; or the fourth indicator of perception target A = RSRP of target signal - the first indicator of perception target A - the first indicator of perception target B; (assuming there are two perception targets: A and B)
[0781] Method 2: Calculate a perception-related index for multiple perception targets. For example, Figure 21 The paths associated with any perception target are determined, and then these paths are determined as the paths associated with the perception target; this is equivalent to treating multiple perception targets as a virtual perception target, and then calculating the perception-related indicators corresponding to the virtual perception target.
[0782] It should be noted that the above calculation method is only an example, and the embodiments of this application do not limit the specific calculation method of the indicator.
