[0044] For better understanding, the related concepts and principles involved in the embodiments of this application are explained below.
[0045] Communication perception integration / communication and sensing integration:
[0046] Future Beyond 5G thGeneration, B5G) and 6G wireless communication systems are expected to provide various high-precision sensing services, such as indoor positioning for robot navigation, Wi-Fi sensing in smart homes, and radar sensing in autonomous vehicles. Sensing and communication systems are usually designed separately and occupy different frequency bands. Integrated Sensing And Communication (ISAC) enables the sharing of the same frequency band and hardware between sensing and communication systems, improving frequency efficiency and reducing hardware costs. ISAC will become a key technology for future wireless communication systems to support many important application scenarios. Typical applications of ISAC include: navigation and obstacle avoidance for autonomous vehicles, Wi-Fi-based indoor positioning and activity recognition, communication and sensing for unmanned aerial vehicles, extended-range (XR), integrated radar and communication, etc. Each application has different requirements, limitations, and regulatory issues. ISAC has attracted great research interest and attention in both academia and industry.
[0047] ISAC achieves an integrated low-cost implementation of dual functions of communication and sensing through the sharing of hardware devices and software-defined functions. Its main characteristics are: first, the architecture is unified and simplified; second, the functions are reconfigurable and scalable; third, the efficiency is improved and the cost is reduced. The advantages of integrated communication and sensing mainly include three aspects: first, the device cost is reduced and the size is decreased; second, the spectrum utilization rate is improved; third, the system performance is improved.
[0048] Currently, the typical scenarios of integrated communication and sensing that are expected to be achieved through technical upgrades based on the 5G communication system architecture are shown in Table 1 below.
[0049] Table 1. Typical Scenarios of Integrated Communication and Sensing
[0050]
[0051]
[0052] According to the different sensing signal sending nodes and receiving nodes, it is divided into 6 basic sensing methods, as Figure 1b shown, specifically including:
[0053] (1) Base station self-transmitting and self-receiving sensing: In this sensing method, base station A sends a sensing signal and performs sensing measurement by receiving the echo of the sensing signal;
[0054] (2) Air interface sensing between base stations: Base station B receives the sensing signal sent by base station A and performs sensing measurement;
[0055] (3) Uplink air interface sensing: Base station A receives the sensing signal sent by terminal A and performs sensing measurement;
[0056] (4) Downlink air perception: The terminal B receives the perception signal sent by the base station B and performs perception measurement;
[0057] (5) Terminal self-transmission and self-reception perception: The terminal A sends a perception signal and performs perception measurement by receiving the echo of the perception signal.
[0058] (6) Inter-terminal sidelink (SL) perception: The terminal B receives the perception signal sent by the terminal A and performs perception measurement.
[0059] It should be noted that Figure 1b each perception method takes a perception signal sending node and a perception signal receiving node as examples. In an actual system, according to different perception use cases and perception requirements, one or more different perception methods can be selected, and there can be one or more sending nodes and receiving nodes for each perception method. The perception targets in the figure take people and vehicles as examples, and it is assumed that neither people nor vehicles carry or install signal transceiver devices. The perception targets in the actual scenario will be more diverse.
[0060] In integrated communication and sensing, the performance of the sensing system and the use of power resources can be optimized through the adaptive adjustment of the spatial domain resources of the sensing signal. Among them, the spatial domain resources refer to the transmitting antenna pattern and receiving antenna pattern of the sensing signal; the transmitting antenna pattern indicates the number and antenna spacing of the antennas used to transmit the sensing signal, and determines the transmitting antenna gain of the sensing signal; the receiving antenna pattern indicates the number and antenna spacing of the antennas used to receive the sensing signal, and determines the receiving antenna gain of the sensing signal. At present, the method for determining the spatial domain resources of the sensing signal in the sensing system is not perfect, resulting in poor sensing performance after the adaptive adjustment of the spatial domain resources of the sensing signal in some scenarios. To address this problem, the embodiments of this application propose a method for determining signal spatial domain resources.
[0061] Next, in conjunction with the accompanying drawings, through some embodiments and their application scenarios, the signal spatial domain resource determination method, device, communication equipment, etc. provided by the embodiments of this application will be described in detail.
[0062] Please refer to Figure 2 , Figure 2 which is a flowchart of a signal spatial domain resource determination method provided by the embodiments of this application, and the method is executed by a first device. As Figure 2 shown, the method includes the following steps:
[0063] Step 201, the first device obtains a measurement value of a target metric corresponding to a first signal, where the target metric is related to the signal quality of a signal path associated with a sensing target.
[0064] It should be noted that the signal spatial domain resource determination method provided in the embodiments of the present application can be applied to the self-transmitting and self-receiving sensing mode in communication perception integration (such as base station self-transmitting and self-receiving sensing, terminal self-transmitting and self-receiving sensing), and the A-transmitting and B-receiving sensing mode (such as air interface sensing between base stations, sidelink sensing between terminals, etc.). Among them, the first device includes, but is not limited to, communication devices such as base stations and terminals.
[0065] Optionally, the first signal may be a sensing signal, such as a dedicated signal for sensing services; or, the first signal may also be a communication signal, such as a reference signal, a synchronization signal, etc. Among them, the first signal may be a signal sent by the first device (i.e., the first device is the transmitting end device of the first signal), or it may also be a signal received by the first device (i.e., the first device is the receiving end device of the first signal), or the first signal is a signal sent or received by the second device.
[0066] Exemplarily, the first device obtains a measurement value of the target metric of the first signal, where the target metric is related to the signal quality of the signal path associated with the sensing target, such as the received power, interference, and noise power of the signal path associated with the sensing target.
[0067] Optionally, the target metric includes at least one of the following:
[0068] The first metric, which is the linear average value (in watts) of the received power of the signal path associated with the sensing target in the channel response measured for the target signal on the target resource carrying the target signal. Here, the target resource may be a time domain resource unit, or a frequency domain resource unit, or a time-frequency domain resource unit. It should be noted that the time domain resource unit may be an Orthogonal Frequency Division Multiplexing (OFDM) symbol, the frequency domain resource unit may be a subcarrier, and the time-frequency domain resource unit may be a Resource Element (RE). An RE refers to occupying 1 subcarrier in the frequency domain and 1 OFDM symbol in the time domain. In some scenarios, the first metric can also be understood as the received power of the signal path associated with the sensing target.
[0069] The second indicator, which is the sum of the first linear average value and the second linear average value (in watts). The first linear average value is the linear average of the power of the signal paths other than the signal paths associated with the sensing target in the channel response of the target signal on the target resource. The second linear average value is the linear average of the interference and noise power of signals other than the target signal on the target resource or other resources (such as resources configured by high-layer signaling) other than the target resource. Optionally, the second indicator can be the difference between the total received power and the first indicator; where the total received power can be expressed as: the linear average of the total received power on the target resource (including the received power of signals from serving cells and non-serving cells, adjacent channel interference, and thermal noise, etc.) (in watts); or, the total received power = RSSI * K1, where K1 is a coefficient, and the measurement resource of RSSI is the target resource or other resources (such as resources configured by high-layer signaling), and the definition of RSSI can refer to relevant protocols (such as 3GPP TS38.215).
[0070] The third indicator, which is the linear average of the interference and noise power of signals other than the target signal on the target resource or other resources (such as resources configured by high-layer signaling) other than the target resource (in watts). Optionally, the third indicator can be the difference between the total received power and the received power of the target signal, where the received power of the target signal is the RSRP of the target signal, and the definition of RSRP can refer to relevant protocols (such as 3GPP TS38.215).
[0071] The fourth indicator, which is the linear average of the power of the signal paths other than the signal paths associated with the sensing target in the channel response of the target signal on the target resource (in watts). Optionally, the fourth indicator can be the difference between the RSRP of the first signal and the first indicator.
[0072] The fifth indicator, which is the ratio of the first indicator to the second indicator;
[0073] The sixth indicator, which is the ratio of the first indicator to the third indicator;
[0074] The seventh indicator, which is the ratio of the first indicator to the fourth indicator;
[0075] The eighth indicator, which is the ratio of the first indicator to the total received power of the first signal; optionally, the eighth indicator can also be the product of the ratio of the first indicator to the total received power of the first signal and a preset coefficient K2;
[0076] Wherein, the target signal is the first signal or the second signal. It should be noted that the above fifth index, sixth index, seventh index, and eighth index can be understood as signal-to-noise and interference ratio (SINR), signal-to-noise ratio (SNR), signal-to-interference ratio (SIR), or reference signal received quality (RSRQ), etc.
[0077] Optionally, before the first device obtains the measurement value of the target index corresponding to the first signal, the method further includes at least one of the following:
[0078] The first device obtains at least part of the information in the first configuration information sent by the sensing functional network element;
[0079] The first device obtains at least part of the information in the first configuration information based on protocol agreements;
[0080] Wherein, the first configuration information is used to indicate the target index. Here, it can be understood that the first configuration information indicates the index type of the target index.
[0081] Exemplarily, the first configuration information may be used to indicate which one or more of the above first index to eighth index the target index is. For example, if the first configuration information is used to indicate that the target index is the first index, the first device determines the measurement value of the first index according to the first configuration information, further determines the first parameter adjustment information according to the measurement value of the first index, and sends the first parameter adjustment information to the sending-end device and / or the receiving-end device of the second signal. For example, the adjustment information of the transmission power and the relevant parameters of the transmission antenna (such as the transmission antenna gain) are sent to the sending-end device of the second signal, and the relevant parameters of the receiving antenna (such as the receiving antenna gain) are sent to the receiving-end device of the second signal, so that the sending-end device and / or the receiving-end device can determine the first parameters of the second signal according to the first parameter adjustment information. Of course, the first configuration information may also be used to indicate other indexes, which are not specifically listed here.
[0082] In the embodiment of the present application, before the first device obtains the measurement value of the target index, it obtains the first configuration information and determines the index type of the target index according to the first configuration information. Thus, the first device can determine which one or more indexes the target index is, which is more helpful for the first device to obtain the measurement value of the target index to ensure that the first device can determine the transmission power adjustment information according to the measurement value of the target index.
[0083] Optionally, the first device may obtain the first configuration information in the following manner:
[0084] The first device obtains at least part of the information in the first configuration information sent by the sensing function network element;
[0085] The first device obtains at least part of the information in the first configuration information based on protocol agreements.
[0086] For example, the first configuration information is used to indicate two of the first to eighth metrics, that is, the target metrics include two metrics. These two metrics may be sent by the sensing function network element, or these two metrics may be those that must be obtained according to protocol agreements, or one of the metrics is those that must be obtained according to protocol agreements, and the other metric is sent by the sensing function network element. Furthermore, it makes the way for the first device to obtain the first configuration information more flexible.
[0087] Among them, the sensing function network element, which can also be called the sensing network element or sensing network function, can be on the RAN side or the core network side. It refers to a network node in the core network and / or RAN that is responsible for at least one of the functions such as sensing request processing, sensing resource scheduling, sensing information interaction, and sensing data processing. It can be upgraded based on the AMF or LMF in the 5G network, or it can be other network nodes or newly defined network nodes. Specifically, the functional characteristics of the sensing function network element may include at least one of the following:
[0088] 1) Perform target information interaction with a wireless signal transmitting device and / or a wireless signal measuring device (including the target terminal or the serving base station of the target terminal or the base station associated with the target area). The target information includes sensing processing requests, sensing capabilities, sensing auxiliary data, sensing measurement quantity types, sensing resource configuration information, etc., to obtain the value of the target sensing result or sensing measurement quantity (uplink measurement quantity or downlink measurement quantity) sent by the wireless signal measuring device; among them, the wireless signal can also be called the sensing signal.
[0089] 2) Determine the sensing method to be used based on factors such as the type of sensing service, sensing service consumer information, required sensing quality of service (QoS) requirement information, sensing capabilities of the wireless signal transmitting device, and sensing capabilities of the wireless signal measuring device. The sensing method may include: base station A transmits and base station B receives, or the base station transmits and the terminal receives, or base station A transmits and receives by itself, or the terminal transmits and the base station receives, or the terminal transmits and receives by itself, or terminal A transmits and terminal B receives, etc.
[0090] 3) Determine the sensing devices serving the sensing service based on factors such as the type of the sensing service, information of the sensing service consumers, required sensing QoS requirement information, sensing capabilities of the wireless signal transmitting devices, sensing capabilities of the wireless signal measuring devices, etc., where the sensing devices include wireless signal transmitting devices and / or wireless signal measuring devices.
[0091] 4) Manage the overall coordination and scheduling of the resources required for the sensing service, such as performing corresponding configuration on the sensing resources of the base station and / or the terminal.
[0092] 5) Perform data processing on the values of the sensing measurement quantities, or perform calculations to obtain sensing results. Further, verify the sensing results, estimate the sensing accuracy, etc.
[0093] In the embodiment of the present application, the first device also needs to determine the signal paths associated with the sensing target. Optionally, the method further includes the following steps:
[0094] The first device performs channel estimation on the target signal and the received signal corresponding to the target signal to obtain a channel response, and transforms the channel response to the first dimension; where the target signal is the first signal or the second signal;
[0095] The first device determines the signal paths associated with the sensing target among the signal paths corresponding to the first dimension;
[0096] Where the first dimension includes at least one of the following:
[0097] Delay dimension;
[0098] Doppler dimension;
[0099] Azimuth angle dimension;
[0100] Elevation angle dimension.
[0101] Exemplarily, taking the target signal as the first signal as an example, the first device performs channel estimation on the first signal and the received signal corresponding to the first signal to obtain a channel response, and further transforms the channel response to the first dimension, such as the delay dimension, and then determines the signal paths associated with the sensing target among the signal paths corresponding to the delay dimension. For example, the signal paths with a delay exceeding the second preset threshold can be used as the signal paths associated with the sensing target. Of course, the first dimension may also be other possible situations, and the determination method of the signal paths associated with the sensing target may also be other possible situations, which are not specifically listed here.
[0102] In the embodiments of the present application, the channel response is obtained by performing channel estimation on the target signal, and the channel response is transformed into the first dimension. The signal path associated with the sensing target is determined from the signal paths corresponding to the first dimension, and the first dimension includes at least one of a time delay dimension, a Doppler dimension, an azimuth angle dimension, and an elevation angle dimension, thereby making the determination method of the signal path associated with the sensing target more flexible.
[0103] Optionally, when the first device determines the signal path associated with the sensing target among the signal paths corresponding to the first dimension, it includes:
[0104] The first device takes the signal path that satisfies the first condition among the signal paths corresponding to the first dimension as the signal path associated with the sensing target;
[0105] Wherein, the first condition includes at least one of the following:
[0106] The first target parameter of the signal path exceeds a first preset threshold or is within a first specific interval range;
[0107] The difference between the first target parameter of the signal path and the first target parameter of the first-arrival signal path or the reference signal path exceeds a second preset threshold or is within a second specific interval range;
[0108] The second target parameter of the signal path satisfies a preset modulation rule;
[0109] Wherein, the first parameter includes at least one of the following: amplitude, power, intensity, energy, Doppler, time delay, angle;
[0110] The second target parameter includes at least one of the following: amplitude, power, intensity, energy, phase.
[0111] For example, the first device takes the signal path whose amplitude exceeds the first preset threshold among the signal paths corresponding to the first dimension as the signal path associated with the sensing target, or takes the signal path whose amplitude satisfies the preset modulation rule as the signal path associated with the sensing target. Of course, the first condition may also be other possible situations as described above, and the determination method of the signal path associated with the sensing target may also include other possible situations, thereby making the determination method of the signal path associated with the sensing target more flexible.
[0112] It should be noted that the first preset threshold or the first specific interval range corresponding to different first parameters may be different, and the preset modulation rules corresponding to different second target parameters may also be different.
[0113] Optionally, when the first device selects the signal path that satisfies the first condition as the signal path associated with the sensing target among the signal paths corresponding to the first dimension, it includes:
[0114] The first device determines a first set of signal paths in the signal paths corresponding to the first dimension, and for each signal path in the first set of signal paths, a third target parameter exceeds a third preset threshold, where the third target parameter includes at least one of the following: amplitude, power, intensity, energy;
[0115] The first device uses the signal paths that meet the first condition in the first set of signal paths as the signal paths associated with the sensing target.
[0116] In the embodiments of the present application, after the first device determines the signal paths corresponding to the first dimension, it further determines a first set of signal paths from the signal paths corresponding to the first dimension according to the third target parameter of the signal paths, and then uses the signal paths that meet the first condition in the first set of signal paths as the signal paths associated with the sensing target. Thus, it helps to improve the accuracy of determining the signal paths associated with the sensing target.
[0117] It should be noted that the third preset thresholds corresponding to different third target parameters may be different.
[0118] Optionally, the first configuration information is further used to indicate at least one of the following:
[0119] The first dimension;
[0120] The first condition;
[0121] Using the signal paths that meet the first condition as the signal paths associated with the sensing target;
[0122] The first target parameter;
[0123] The second target parameter;
[0124] The third target parameter;
[0125] The first preset threshold;
[0126] The second preset threshold;
[0127] The third preset threshold;
[0128] The first specific interval range;
[0129] The second specific interval range.
[0130] For better understanding, the above several indicators and the determination of the signal paths associated with the sensing target are described in detail below by taking the target signal as the first signal as an example.
[0131] Calculation method of the first indicator:
[0132] The terminal performs channel estimation based on the transmitted first signal X(k) and the received signal Y(k) corresponding to the first signal to obtain the channel response H(k) = Y(k) / X(k), where k = 0, 1, 2, …, K - 1, and k represents the resource unit (target resource) index. After the terminal obtains the channel response H(k), it transforms it to the first dimension and determines the signal paths associated with the sensing target in the first dimension. Then, it calculates the power of the signal paths associated with the sensing target and uses it as the first metric. If the signal paths associated with the sensing target include multiple signal paths, it calculates the sum of the powers of the multiple signal paths as the first metric.
[0133] Among them, the first dimension includes one of the following:
[0134] Delay dimension;
[0135] Doppler dimension;
[0136] Azimuth angle dimension;
[0137] Elevation angle dimension;
[0138] A dimension that combines at least two of the delay dimension, Doppler dimension, azimuth angle dimension, and elevation angle dimension. For example, delay-Doppler dimension, delay-Doppler-angle dimension, etc.
[0139] For example, if H(f) is the channel response, where f = 0, 1, 2, …, N - 1 represents the frequency-domain sampling points (such as subcarrier indices), then it can be transformed to the delay dimension (the first dimension) by performing an inverse Fourier transform on H(f); also, for example, if H(f,t) is the channel response, where f = 0, 1, 2, …, N - 1 represents the frequency-domain sampling points (such as subcarrier indices) and t = 0, 1, 2, …, M - 1 represents the time-domain sampling points (such as OFDM symbol indices), then it can be transformed to the delay-Doppler dimension (the first dimension) by performing an inverse Fourier transform along the frequency-domain dimension and a Fourier transform along the time-domain dimension on H(f,t); also, for example, if H(f,t,s) is the channel response, where f = 0, 1, 2, …, N - 1 represents the frequency-domain sampling points (such as subcarrier indices), t = 0, 1, 2, …, M - 1 represents the time-domain sampling points (such as OFDM symbol indices), and s = 0, 1, 2, …, P - 1 represents the spatial-domain sampling points (antenna indices or port indices), then it can be transformed to the delay-Doppler-angle dimension (the 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 on H(f,t,s).
[0140] Among them, the method for determining the signal paths associated with the sensing target (abbreviated as sensing paths) in the channel response measured from the first signal is as follows:
[0141] - Determine the first set of paths. The paths in the first set of paths (i.e., signal paths, hereinafter simply referred to as paths) include the paths in all paths whose intensity / power / energy exceeds a preset threshold after the channel response is transformed into the first dimension. (For example Figure 3 in, paths 0, 1, 2, 3 are the paths in the first set of paths; among them, Figure 3 the horizontal axis in is the first dimension, and the vertical axis is the normalized amplitude);
[0142] - The paths (signal paths) associated with the sensing target are the paths in the first set of paths that satisfy the first condition.
[0143] Among them, the first condition includes at least one of the following:
[0144] · The Doppler of the path exceeds the first preset threshold or is within the first specific range;
[0145] · The delay of the path exceeds the first preset threshold or is within the first specific range;
[0146] · The angle of the path exceeds the first preset threshold or is within the first specific range;
[0147] · The Doppler difference between the path and the first-arriving path (e.g., line of sight (LOS) path) or the reference path (e.g., the signal path reflected by a specific target (e.g., Reconfigurable Intelligent Surface (RIS) / Backscatter / other known passive targets, etc.)) exceeds the second preset threshold or is within the second specific range;
[0148] · The delay difference between the path and the first-arriving path (e.g., LOS path) or the reference path (e.g., the signal path reflected by a specific target (e.g., RIS / Backscatter / other known passive targets, etc.)) exceeds the second preset threshold or is within the second specific range;
[0149] · The angle difference between the path and the first-arriving path (e.g., LOS path) or the reference path (e.g., the signal path reflected by a specific target (e.g., RIS / Backscatter / other known passive targets, etc.)) exceeds the second preset threshold or is within the second specific range.
[0150] Among them, the above preset thresholds or specific ranges are sent by other devices to the receiving device and determined by other devices according to sensing prior information or sensing requirements. Alternatively, the above preset thresholds or set ranges are determined by the receiving device according to sensing prior information or sensing requirements.
[0151] For example, in FIG. 1, the paths 0, 1, 2, and 3 are paths in the first path set, where the paths 2 and 3 are sensing paths that meet the first condition (for example, their time delays meet a preset threshold), and the paths 0 and 1 are paths associated with other scatterers.
[0152] Among them, the sensing prior information or sensing requirements include the following information:
[0153] · Sensing service or sensing service type. The sensing service can be, for example, detecting whether a target exists, positioning, speed detection, distance detection, angle detection, acceleration detection, material analysis, component analysis, shape detection, category classification, Radar Cross Section (RCS) detection, polarization scattering characteristic detection, fall detection, intrusion detection, quantity statistics, indoor positioning, gesture recognition, lip reading recognition, gait recognition, expression recognition, face recognition, breathing monitoring, heart rate monitoring, pulse monitoring, humidity / brightness / temperature / atmospheric pressure monitoring, air quality monitoring, weather condition monitoring, environment reconstruction, terrain and landform, building / vegetation distribution detection, human or vehicle flow detection, crowd density / vehicle density detection, etc.; The sensing service type can classify multiple different sensing services according to certain characteristics. For example, it can be classified into detection-type sensing services (such as intrusion detection, fall detection), parameter estimation-type sensing services (distance, angle, speed calculation), recognition-type sensing services (action recognition, identity recognition), etc. according to function. It can also be classified according to the sensing range (close-range sensing, medium-range sensing, long-range sensing), according to the sensing fineness (coarse-grained sensing, fine-grained sensing, etc.), according to power consumption / energy consumption, according to resource occupancy, etc.
[0154] · Sensing target area: It refers to the position area where the sensing object may exist, or the position area where imaging or environment reconstruction needs to be performed;
[0155] · Sensing object type: Classify the sensing object according to the possible motion characteristics of the sensing object. Each sensing object type contains information such as the motion speed, motion acceleration, and typical RCS of typical sensing objects;
[0156] · Number of sensing targets.
[0157] Exemplarily, for frequency range 1, the reference point of 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 shall not be lower than that of any single receiving channel. For frequency range 2, the first metric measured by a certain receiving channel needs to be obtained by measuring the combined signals on multiple antenna elements corresponding to that receiving channel.
[0158] Optionally, the calculation method of the first metric can also be:
[0159] The difference between the power of the signal paths associated with the perceived target in the first dimension and is used as the first metric, where N 1 represents the number of paths associated with the perceived target. is the average power of multiple paths outside the first path set in the first dimension.
[0160] The calculation method of the received power of the first signal is as follows:
[0161] The received power of the first signal can be that after the receiving device obtains the channel response H(k), it transforms it into the first dimension, determines the first path set in the first dimension, and then calculates the sum of the powers of all paths in the first path set.
[0162] Optionally, the calculation method of the received power of the first signal can also be:
[0163] The difference between the sum of the powers of all paths in the first path set in the first dimension and where N 2 represents the number of paths in the first path set, is the average power of multiple paths outside the first path set in the first dimension.
[0164] The calculation method of the total received power is as follows:
[0165] Total received power
[0166] The calculation method of the second metric is as follows:
[0167] The channel response H(k) is subjected to the first filtering process to obtain H filter1 (k), and then the received signal Y filter1 (k) after the first filtering process is calculated according to H filter1 (k) and the first signal X(k), that is, Y filter1(k) = H filter1 (k)X(k). Then subtract the received signal Y filter1 (k) from the received signal Y(k) to obtain the interference and noise signal Y σ1 (k), that is, Y σ1 (k) = Y(k) - Y filter1 (k), and then calculate to obtain the second index
[0168] Among them, the first filtering process is used to eliminate the noise and interference in the first dimension and the paths not associated with the perceived target. For example, the first filtering process will Figure 3 set the amplitudes of the paths other than the paths associated with the perceived target in filter1 to zero. The channel response H
[0169] after the first filtering process does not contain noise, interference, and paths not associated with the perceived target, and only contains the paths associated with the perceived target.
[0170] The calculation method of the third index is as follows: filter2 Perform a second filtering process on the channel response H(k) to obtain H filter2 (k), and then calculate the received signal Y filter2 (k) after the second filtering process according to H filter2 (k) and the first signal X(k), that is, Y filter2 (k) = H filter2 (k)X(k). Then subtract the received signal Y σ2 (k) from the received signal Y(k) to obtain the interference and noise signal Y σ2 (k), that is, Y filter2 (k) = Y(k) - Y
[0171] The second filtering process can be a noise interference suppression process in the first dimension (for example Figure 3 set the amplitudes of the paths other than the first path set in filter2 to zero), or a minimum mean square error (MMSE) filter. The channel response H
[0172] after the second filtering process does not contain noise and interference, and only contains the paths in the first path set.
[0173] Or, the calculation method of the third index can also be: Calculate the third index P σ2 according to the average power of multiple paths outside the first path set in the first dimension That is, where N represents the number of sampling points in the first dimension.
[0174] It should be noted that if the receiving device determines multiple sensing targets, or the receiving device obtains the number of sensing targets based on sensing prior information or sensing requirements, there are the following methods:
[0175] Method 1: Calculate the target indicators of each sensing target separately. For example, in Figure 3 the paths associated with each sensing target are determined respectively, and then the target indicators of each item corresponding to each sensing target are calculated respectively; when calculating the second indicator corresponding to a certain sensing target (such as sensing target A), there are two methods: namely, the second indicator of sensing target A = total received power - the first indicator of sensing target A; or, the second indicator of sensing target A = total received power - the first indicator of sensing target A - the first indicator of sensing target B; (assuming there are two sensing targets in total: A and B); similarly, there are also two calculation methods for the fourth indicator: the fourth indicator of sensing target A = RSRP of the first signal - the first indicator of sensing target A; or, the fourth indicator of sensing target A = RSRP of the first signal - the first indicator of sensing target A - the first indicator of sensing target B; (assuming there are two sensing targets in total: A and B)
[0176] Method 2: Calculate a target indicator for multiple sensing targets. For example, in Figure 3 the paths associated with any sensing target are determined, and then these paths are all regarded as the paths associated with the sensing target; it is equivalent to regarding multiple sensing targets as a virtual sensing target, and then calculating the target indicator corresponding to this virtual sensing target.
[0177] It should be noted that the target indicator corresponding to the second signal can also be calculated in the above manner, which will not be elaborated here.
[0178] Step 202: The first device determines first parameter adjustment information according to the measured value of the target indicator.
[0179] Wherein, the first parameter adjustment information is used to indicate the first parameter of the second signal, and the first parameter is the product of the transmission power of the signal, the transmission antenna gain of the signal, and the reception antenna gain of the signal. It can be understood that the first parameter of the second signal is also the product of the transmission power of the second signal, the transmission antenna gain of the second signal, and the reception antenna gain of the second signal; the first parameter of the first signal is also the product of the transmission power of the first signal, the transmission antenna gain of the first signal, and the reception antenna gain of the first signal.
[0180] It should be noted that the second signal may be a signal of the same type as the first signal, or in some scenarios, the second signal is the first signal itself, and the first parameter adjustment information is used to indicate the first parameter corresponding to the first signal at a subsequent transmission time. Optionally, the second signal may be a sensing signal, such as a dedicated signal for sensing services; or, the second signal may also be a communication signal, such as a reference signal, a synchronization signal, etc.
[0181] In the embodiments of the present application, the first device may obtain a measurement value of a target metric corresponding to the first signal transmitted at the first time, and determine the first parameter adjustment information according to the measurement value of the target metric. For example, the first parameter adjustment information is used to indicate the first parameter of the second signal at the second time. Exemplarily, the second signal may be a signal of the same type as the first signal, then the first device may determine the first parameter adjustment information of the first signal at the second time according to the measurement value of the target metric. Wherein, the second time is after the first time.
[0182] Optionally, the first time and the second time may include multiple time points, such as the first signals transmitted on multiple OFDM symbols. In some embodiments, signal processing of the first signals on multiple OFDM symbols is required to obtain the target metric.
[0183] It should be noted that the beam direction or Quasi co-location (QCL) relationship between the first signal at the first time and the second signal (or it can also be the first signal) at the second time remains unchanged, that is, the first parameter is adjusted per beam.
[0184] In the embodiments of the present application, the first device obtains a measurement value of a target metric corresponding to the first signal, and further determines the first parameter adjustment information according to the measurement value of the target metric, where the first parameter adjustment information is used to indicate the first parameter of the second signal, and the first parameter is the product of the transmit power of the signal, the transmit antenna gain of the signal, and the receive antenna gain of the signal. It can be understood that for a sensing signal, the transmit power, transmit antenna gain, and receive antenna gain of the signal jointly determine the received power of the signal path reflected by the sensing target. In the embodiments of the present application, the first device can jointly adjust the transmit power, transmit antenna gain, and receive antenna gain of the sensing signal according to the target metric, that is, can adjust the received power of the sensing signal, which helps to improve the sensing performance and optimize resource allocation.
[0185] Optionally, the method further includes any one of the following:
[0186] The first device sends at least part of the first parameter adjustment information to the target device;
[0187] The first device sends at least part of the first parameter adjustment information to the target device through the sensing functional network element;
[0188] Wherein, the target device includes at least one of the following: the sending-end device of the second signal, the receiving-end device of the second signal.
[0189] For example, the first device is a UE. The UE receives the first signal sent by the base station at the first moment, processes the signal to obtain the measured value of the target index, determines the first parameter adjustment information according to the measured value of the target index, and further sends at least part of the first parameter adjustment information to the sending-end device (base station) of the second signal and / or the receiving-end device (UE) of the second signal. For example, it sends the adjustment information of the transmission power and the relevant parameters of the transmitting antenna (such as the transmitting antenna gain) to the sending-end device (base station) of the second signal, and sends the relevant parameters of the receiving antenna (such as the receiving antenna gain) to the receiving-end device (UE) of the second signal. Or, the UE sends at least part of the first parameter adjustment information to the sensing functional network element, and the sensing functional network element sends at least part of the first parameter adjustment information to the sending-end device (base station) of the second signal and / or the receiving-end device (UE) of the second signal. Further, the sending-end device of the second signal and / or the receiving-end device of the second signal can determine the first parameter of the second signal at the second moment according to the first parameter adjustment information, that is, determine at least one of the transmission power, the transmitting antenna gain, and the receiving antenna gain of the second signal, which helps to ensure the sensing performance and optimize the system efficiency.
[0190] Optionally, the first parameter adjustment information includes at least one of the following:
[0191] The identity (ID) of the first signal;
[0192] The ID of the second signal;
[0193] The target first parameter, where the target first parameter is the first parameter of the second signal;
[0194] The difference between the target first parameter and the first parameter of the first signal;
[0195] The ratio of the target first parameter to the first parameter of the first signal;
[0196] The step value of the target first parameter and the first parameter of the first signal;
[0197] The target transmission power, where the target transmission power is the transmission power of the second signal;
[0198] The difference between the target transmit power and the transmit power of the first signal;
[0199] The ratio of the target transmit power to the transmit power of the first signal;
[0200] The step value of the target transmit power with respect to the transmit power of the first signal;
[0201] The target transmit antenna gain, where the target transmit antenna gain is the transmit antenna gain of the second signal;
[0202] The difference between the target transmit antenna gain and the transmit antenna gain of the first signal;
[0203] The ratio of the target transmit antenna gain to the transmit antenna gain of the first signal;
[0204] The step value of the target transmit antenna gain with respect to the transmit antenna gain of the first signal;
[0205] The target transmit antenna element number, where the target transmit antenna element number is the transmit antenna element number of the second signal;
[0206] The difference between the target transmit antenna element number and the transmit antenna element number of the first signal;
[0207] The ratio of the target transmit antenna element number to the transmit antenna element number of the first signal;
[0208] The step value of the target transmit antenna element number with respect to the transmit antenna element number of the first signal;
[0209] The indication of the transmit antenna pattern of the second signal;
[0210] The target receive antenna gain, where the target receive antenna gain is the receive antenna gain of the second signal;
[0211] The difference between the target receive antenna gain and the receive antenna gain of the first signal;
[0212] The ratio of the target receive antenna gain to the receive antenna gain of the first signal;
[0213] The step value of the target receive antenna gain with respect to the receive antenna gain of the first signal;
[0214] The target receive antenna element number, where the target receive antenna element number is the receive antenna element number of the second signal;
[0215] The difference between the target receive antenna element number and the receive antenna element number of the first signal;
[0216] The ratio of the number of target receiving antenna units to the number of receiving antenna units of the first signal;
[0217] The step value of the number of target receiving antenna units to the number of receiving antenna units of the first signal;
[0218] The indication of the receiving antenna pattern of the second signal.
[0219] Exemplarily, when the first parameter adjustment information includes the above-mentioned target first parameter, or the difference / ratio / step value between the target first parameter and the first parameter of the first signal, the transmitting device of the first signal obtains the first parameter adjustment information (that is, at least one of the target first parameter, the difference / ratio / step value between the target first parameter and the first parameter of the first signal), and can determine the first parameter of the second signal (which can also be the first signal). Then, the transmitting device of the first signal can determine the adjustment amount of the transmitting power and the transmitting antenna resources according to the transmitting power of the device itself and the margin of the transmitting antenna, so as to realize the adjustment of the power of the sensing signal.
[0220] Alternatively, in some embodiments, the first device knows the transmitting power, transmitting antenna gain, or receiving antenna gain of the first signal at the first moment. The first device can directly determine the transmitting power, transmitting antenna gain, or receiving antenna gain of the first signal (that is, the second signal) at the second moment according to the measured value of the target index.
[0221] Or, in other embodiments, the first device does not need to know the transmitting power, transmitting antenna gain, or receiving antenna gain of the first signal at the first moment. The first device can determine the difference, ratio, or step value between the transmitting power, transmitting antenna gain, or receiving antenna gain of the first signal (that is, the second signal) at the second moment and the transmitting power, transmitting antenna gain, or receiving antenna gain of the first signal at the first moment according to the measured value of the target index. For example, according to the measured value of the target index, the first device determines that: the transmitting power of the first signal at the second moment needs to be increased by X1 dB compared with the transmitting power of the first signal at the first moment, the transmitting antenna gain of the first signal at the second moment needs to be increased by X2 dB compared with the transmitting antenna gain of the first signal at the first moment, and the transmitting antenna gain of the first signal at the second moment needs to be increased by X3 dB compared with the transmitting antenna gain of the first signal at the first moment; then X1 + X2 + X3 dB is the gain that the expected target index can obtain.
[0222] It can be understood that the determination of the above-mentioned first parameter adjustment information may also be other possible situations, which are not listed here too much.
[0223] In the embodiments of the present application, the first device determines first parameter adjustment information according to the measured value of the target metric, and further, based on the first parameter adjustment information, it is possible to determine spatial domain resources such as the transmission power, transmission antenna gain, and receiving antenna gain of the second signal at the second moment, thereby clarifying the method of determining the spatial domain resources of the sensing signal in integrated communication and sensing, which helps to ensure the sensing performance and optimize the system efficiency.
[0224] Optionally, the first device obtains the measured value of the target metric corresponding to the first signal, including:
[0225] The first device determines the measured value of the target metric;
[0226] The first device obtains the measured value of the target metric determined by the second device.
[0227] It can be understood that the first device can determine the measured value of the target metric by itself; or, the measured value of the target metric is determined by the second device, and the first device obtains the measured value of the target metric from the second device. For example, the first device receives the measured value of the target metric sent by the second device.
[0228] Optionally, the first device determines the measured value of the target metric, including any one of the following:
[0229] When the first device is the receiving end device of the first signal, the first device performs signal processing on the received first signal to obtain the measured value of the target metric;
[0230] When the first device is not the receiving end device of the first signal, the first device obtains the first measurement quantity sent by the receiving end device of the first signal and determines the measured value of the target metric according to the first measurement quantity.
[0231] That is, if the first device is the receiving end device of the first signal, the first device can directly perform signal processing on the received first signal to obtain the measured value of the target metric. If the first device is not the receiving end device of the first signal, for example, the first device is the device that sends the first signal, the first device obtains the first measurement quantity from the receiving end device of the first signal and determines the measured value of the target metric according to the first measurement quantity.
[0232] Wherein, the first measurement quantity includes at least one of the following:
[0233] The first-level measurement quantities (such as received signals / original channel information) include: complex results of received signals / channel responses, amplitude / phase, I-channel / Q-channel and their operation results, where the operations include addition, subtraction, multiplication, division, matrix addition, subtraction, multiplication, matrix transpose, trigonometric relation operations, square root operations, power operations, etc., as well as threshold detection results of the above operation results, maximum or minimum extraction results, etc.; the operations also include Fast Fourier Transform (FFT), Inverse Fast Fourier Transform (IFFT), Discrete Fourier Transform (DFT), Inverse Discrete Fourier Transform (IDFT), 2D-FFT, 3D-FFT, matched filtering, autocorrelation operations, wavelet transform, digital filtering, etc., as well as threshold detection results of the above operation results, maximum / minimum extraction results, etc.;
[0234] The second-level measurement quantities (which can also be called basic measurement quantities) include: time delay, Doppler, angle, intensity, and multi-dimensional combined representations of time delay, Doppler, angle, intensity;
[0235] The third-level measurement quantities include: distance, speed, orientation, spatial position, acceleration, etc.;
[0236] The fourth-level measurement quantities include: whether the target exists, trajectory, action, expression, vital signs, quantity, imaging result, weather, air quality, shape, material, composition, etc.
[0237] Optionally, in the embodiments of the present application, when the first device is not the receiving end device of the first signal, the method further includes at least one of the following:
[0238] The first device obtains at least part of the information in the second configuration information sent by the sensing function network element;
[0239] The first device obtains at least part of the information in the second configuration information based on protocol agreements;
[0240] Wherein, the second configuration information is used to indicate the measurement quantity type of the first measurement quantity.
[0241] Understandably, if the first device is not the receiving device of the first signal, the first device obtains the first measurement quantity sent by the receiving device of the first signal, and determines the measured value of the target index according to the first measurement quantity. In this case, the first device may first obtain the second configuration information, where the second configuration information is used to indicate the measurement quantity type of the first measurement quantity, that is, the second configuration information is used to indicate which one or several measurement quantities the first measurement quantity is. Furthermore, the first device can then clarify which one or several measurement quantities are to be used to determine the measured value of the target index, so as to ensure that the first device can determine the transmission power adjustment information according to the measured value of the target index.
[0242] Exemplarily, the second configuration information is used to indicate which two measurement quantities the first measurement quantity includes. The types of these two measurement quantities may be sent by the sensing function network element, or the types of these two measurement quantities may be those that must be obtained according to the protocol agreement, or one of the measurement quantities is those that must be obtained according to the protocol agreement, and the other measurement quantity is sent by the sensing function network element. In this way, it enables the first device to determine which measurement quantities the first measurement quantity includes based on the second configuration information, and also makes the way for the first device to obtain the second configuration information more flexible.
[0243] Optionally, in the embodiments of the present application, the first device determines the first parameter adjustment information according to the measured value of the target index, including at least one of the following:
[0244] The first device determines the first parameter adjustment information according to the measured value of the target index corresponding to the first signal and the first value, so that the target value of the target index corresponding to the second signal is the first value;
[0245] The first device determines the first parameter adjustment information according to the measured value of the target index corresponding to the first signal and the fourth preset threshold, so that the target value of the target index corresponding to the second signal is greater than or equal to the fourth preset threshold;
[0246] The first device determines the first parameter adjustment information according to the measured value of the target index corresponding to the first signal and the fifth preset threshold, so that the target value of the target index corresponding to the second signal is less than or equal to the fifth preset threshold.
[0247] For example, in one embodiment, the target metric is the received power of the signal path associated with the sensing target. The received power of the signal path associated with the sensing target corresponding to the first signal measured at the first moment is -85 dBm, while the expected received power of the signal path associated with the sensing target corresponding to the second signal (which can also be the first signal) at the second moment is -80 dBm (i.e., the first value is -80 dBm). Then, based on these two values, the first parameter adjustment information can be determined to be 5 dB. That is, through the joint adjustment of the transmit power, transmit antenna gain, and receive antenna gain of the second signal, the target metric of the second signal at the second moment is increased by 5 dB.
[0248] Alternatively, in another embodiment, the target metric is the sensed SINR, and the fourth preset threshold is 10 dB. Then, the adjustment target of the transmit power, transmit antenna gain, and receive antenna gain is to make the sensed SINR corresponding to the second signal greater than or equal to 10 dB (i.e., the fourth preset threshold is 10 dB). If the sensed SINR of the first signal measured at the first moment is 6 dB, it is determined that the first parameter adjustment information should be greater than or equal to 4 dB. That is, through the joint adjustment of the transmit power, transmit antenna gain, and receive antenna gain of the second signal, the target metric of the second signal at the second moment is increased by at least 4 dB.
[0249] In yet another embodiment, the target metric is the sensed SINR, and the fifth preset threshold is 20 dB. Then, the adjustment target of the transmit power, transmit antenna gain, and receive antenna gain is to make the sensed SINR corresponding to the second signal less than or equal to 20 dB (i.e., the fifth preset threshold is 20 dB) to avoid waste of airspace resources. If the sensed SINR of the first signal measured at the first moment is 23 dB, the first parameter adjustment information should be less than or equal to -3 dB. Then, through the joint adjustment of the transmit power, transmit antenna gain, and receive antenna gain of the second signal, the target metric of the second signal at the second moment can be reduced by at least 3 dB.
[0250] In the embodiments of the present application, the first device can determine the first parameter adjustment information based on the measured value of the target metric corresponding to the first signal and the first value or preset threshold, so that the target value of the target metric corresponding to the second signal meets the preset first value or preset threshold, thereby enabling better adjustment of airspace resources such as the transmit power of the sensing signal, transmit antenna gain, and receive antenna gain to ensure sensing performance and optimize system efficiency.
[0251] Optionally, before determining the first parameter adjustment information, the method further includes:
[0252] The first device obtains third configuration information, and the third configuration information is used to indicate at least one of the following:
[0253] The target value of the target indicator corresponding to the second signal is a first numerical value;
[0254] The first numerical value;
[0255] The target value of the target indicator corresponding to the second signal is greater than or equal to a fourth preset threshold;
[0256] The fourth preset threshold;
[0257] The target value of the target indicator corresponding to the second signal is less than or equal to a fifth preset threshold;
[0258] The fifth preset threshold.
[0259] It can be understood that before determining the first parameter adjustment information, the first device first obtains the third configuration information, so that the first device can determine the conditions (the first numerical value or the fourth preset threshold or the fifth preset threshold) that the target value of the target indicator corresponding to the second signal needs to meet according to the above content indicated by the third configuration information, which helps the first device to better determine the first parameter adjustment information, that is, to determine the adjustment range of the sensing signal transmission power, the transmission antenna gain, and the receiving antenna gain, and helps to improve the sensing performance.
[0260] Optionally, the first device obtains the third configuration information, including at least one of the following:
[0261] The first device obtains at least part of the information in the third configuration information sent by the sensing function network element;
[0262] The first device obtains at least part of the information in the third configuration information based on protocol agreements.
[0263] Exemplarily, the third configuration information is used to indicate two pieces of information content in the above information content (for example, indicating the first numerical value and indicating that the target value of the target indicator corresponding to the second signal is the first numerical value). These two pieces of information content can be sent by the sensing function network element, or these two pieces of information content can be information that must be obtained according to protocol agreements, or one piece of information content is information that must be obtained according to protocol agreements, and the other piece of information content is sent by the sensing function network element.
