[0044] For better understanding, the relevant concepts and principles involved in the embodiments of this application are explained below.

[0045] Communication perception integration / sensing and communication 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 for 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, improves frequency efficiency, and reduces 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), integration of radar and communication, etc. Each application has different requirements, limitations, and regulatory issues. ISAC has attracted great research interest and attention from 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, 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] According to the different sending and receiving nodes of the sensing signal, it is divided into 6 basic sensing methods, as Figure 1b shown, specifically including:

[0052] (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;

[0053] (2) Air interface sensing between base stations: Base station B receives the sensing signal sent by base station A and performs sensing measurement;

[0054] (3) Uplink air interface sensing: Base station A receives the sensing signal sent by terminal A and performs sensing measurement;

[0055] (4) Downlink air perception: The terminal B receives the perception signal sent by the base station B and performs perception measurement;

[0056] (5) Terminal self-transmitting and self-receiving perception: The terminal A sends a perception signal and performs perception measurement by receiving the echo of the perception signal.

[0057] (6) Inter-terminal sidelink (SL) perception: The terminal B receives the perception signal sent by the terminal A and performs perception measurement.

[0058] 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.

[0059] 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 power of the sensing signal. Currently, in a communication system, the adaptive adjustment of signal power is usually performed through parameters such as reference signal received power (RSRP) and received signal strength indication (RSSI). However, the effect of adjusting the power of the sensing signal through parameters such as RSRP and RSSI is not good. That is, the existing signal power adjustment methods have poor effects when used for adjusting the power of the sensing signal. To address the above problems, an embodiment of this application provides a method for determining the transmission power of a sensing signal.

[0060] Next, in conjunction with the accompanying drawings, through some embodiments and their application scenarios, the signal transmission power determination method, device, equipment, etc. provided by the embodiments of this application will be described in detail.

[0061] Please refer to Figure 2 , Figure 2 which is a flowchart of a signal transmission power determination method provided by an embodiment of this application, and the method is executed by a first device. As Figure 2 shown, the method includes the following steps:

[0062] 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.

[0063] It should be noted that the signal transmission power determination method provided in the embodiments of this application can be applied to the self-transmitting and self-receiving sensing mode in communication and sensing 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.

[0064] 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 (that is, the first device is the sending-end device of the first signal), or may also be a signal received by the first device (that is, 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.

[0065] Exemplarily, the first device obtains a measurement value of a target metric of the first signal, where the target metric is related to the signal quality of a signal path associated with a sensing target, such as the received power, interference, and noise power of the signal path associated with the sensing target.

[0066] Optionally, the target metric includes at least one of the following:

[0067] A first metric, where the first metric is the linear average (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 a target resource carrying the target signal, where 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), where 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 may also be understood as the received power of the signal path associated with the sensing target.

[0068] The second indicator, where the second indicator is the sum of the first linear average value and the second linear average value (in W), the first linear average value is the linear average value of the power of other signal paths except the signal paths associated with the sensing target in the channel response of the target signal on the target resource, and the second linear average value is the linear average value of the interference and noise power of other signals except 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 value (in W) 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, thermal noise, etc.); or, the total received power = RSSI * K1, where K1 is a coefficient, 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).

[0069] The third indicator, where the third indicator is the linear average value (in W) of the interference and noise power of other signals except 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 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).

[0070] The fourth indicator, where the fourth indicator is the linear average value (in W) of the power of other signal paths except the signal paths associated with the sensing target in the channel response of the target signal on the target resource. Optionally, the fourth indicator can be the difference between the RSRP of the first signal and the first indicator.

[0071] The fifth indicator, where the fifth indicator is the ratio of the first indicator to the second indicator;

[0072] The sixth indicator, where the sixth indicator is the ratio of the first indicator to the third indicator;

[0073] The seventh indicator, where the seventh indicator is the ratio of the first indicator to the fourth indicator;

[0074] The eighth indicator, where the eighth indicator 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;

[0075] 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.

[0076] 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:

[0077] The first device obtains at least part of the information in the first configuration information sent by the sensing function network element;

[0078] The first device obtains at least part of the information in the first configuration information based on protocol agreements,

[0079] 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.

[0080] 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 transmit power adjustment information according to the measurement value of the first index, and sends the transmit power adjustment information to the sending device of the first signal, so that the sending device can determine the transmit power of the second signal (which may also be the first signal) according to the transmit power adjustment information. Of course, the first configuration information may also be used to indicate other indexes, which are not specifically listed here.

[0081] In the embodiment of the present application, before obtaining the measurement value of the target index, the first device 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 also 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, so as to ensure that the first device can determine the transmit power adjustment information according to the measurement value of the target index.

[0082] Optionally, the first device may obtain the first configuration information in the following manner:

[0083] The first device obtains at least part of the information in the first configuration information sent by the sensing function network element;

[0084] The first device obtains at least part of the information in the first configuration information based on protocol agreements.

[0085] 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 can be sent by the sensing function network element, or these two metrics can 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, this makes the way for the first device to obtain the first configuration information more flexible.

[0086] Among them, the sensing function network element, which can also be called the sensing network element or sensing 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 from 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 can include at least one of the following:

[0087] 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), where the target information includes a sensing processing request, 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.

[0088] 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 can include: base station A transmits and base station B receives, or base station transmits and terminal receives, or base station A transmits and receives by itself, or terminal transmits and base station receives, or terminal transmits and receives by itself, or terminal A transmits and terminal B receives, etc.

[0089] 3) Determine the sensing devices for the sensing service based on factors such as the type of sensing service, information of the sensing service consumer, required sensing QoS requirement information, sensing capabilities of the wireless signal transmitting device, and sensing capabilities of the wireless signal measuring device, where the sensing devices include a wireless signal transmitting device and / or a wireless signal measuring device.

[0090] 4) Manage the overall coordination and scheduling of the resources required for the sensing service, such as configuring the sensing resources of the base station and / or the terminal accordingly.

[0091] 5) Process the values of the sensing measurement quantities, or perform calculations to obtain the sensing results. Further, verify the sensing results, estimate the sensing accuracy, etc. In the embodiments of the present application, in the process of determining the measured value of the target metric, the first device also needs to determine the signal path associated with the sensing target. Optionally, the method further includes the following steps:

[0092] 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 into a first dimension; wherein, the target signal is the first signal or the second signal;

[0093] The first device determines the signal path associated with the sensing target in the signal paths corresponding to the first dimension;

[0094] Wherein, the first dimension includes at least one of the following:

[0095] Delay dimension;

[0096] Doppler dimension;

[0097] Azimuth angle dimension;

[0098] Elevation angle dimension.

[0099] 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 into a first dimension, such as the delay dimension, and then determines the signal path associated with the sensing target in the signal paths corresponding to the delay dimension. For example, the signal paths with a delay exceeding a 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 path associated with the sensing target may also be other possible situations, which are not specifically listed here.

[0100] In the embodiments of the present application, by performing channel estimation on the target signal to obtain a channel response, transforming the channel response into a first dimension, and determining the signal path associated with the sensing target from the signal paths corresponding to the first dimension, and the first dimension includes at least one of the delay dimension, the Doppler dimension, the azimuth angle dimension, and the elevation angle dimension, the determination method of the signal path associated with the sensing target is made more flexible.

[0101] Optionally, the first device determines the signal path associated with the sensing target in the signal paths corresponding to the first dimension, including:

[0102] In the signal paths corresponding to the first dimension, the first device uses the signal paths that meet the first condition as the signal paths associated with the sensing target;

[0103] Wherein, the first condition includes at least one of the following:

[0104] The first parameter of the signal path exceeds the first preset threshold or is within the first specific interval range;

[0105] The difference between the first parameter of the signal path and the first parameter of the first-arrival signal path or the reference signal path exceeds the second preset threshold or is within the second specific interval range;

[0106] The second parameter of the signal path meets the preset modulation rule;

[0107] Wherein, the first parameter includes at least one of the following: amplitude, power, intensity, energy, Doppler, delay, angle;

[0108] The second parameter includes at least one of the following: amplitude, power, intensity, energy, phase.

[0109] For example, in the signal paths corresponding to the first dimension, the first device uses the signal paths with amplitudes exceeding the first preset threshold as the signal paths associated with the sensing target, or uses the signal paths with amplitudes meeting the preset modulation rule as the signal paths associated with the sensing target. Of course, the first condition can also be other possible situations as mentioned above, and the determination method of the signal paths associated with the sensing target can also include other possible situations, thus making the determination method of the signal paths associated with the sensing target more flexible.

[0110] It should be noted that the first preset threshold or the first specific interval range corresponding to different first parameters can be different, and the preset modulation rules corresponding to different second parameters can also be different.

[0111] Optionally, when the first device uses the signal paths that meet the first condition as the signal paths associated with the sensing target in the signal paths corresponding to the first dimension, it further includes:

[0112] The first device determines a first signal path set in the signal paths corresponding to the first dimension, and the third parameter of each signal path in the first signal path set exceeds the third preset threshold, where the third parameter includes at least one of the following: amplitude, power, intensity, energy;

[0113] The first device uses the signal paths that meet the first condition in the first signal path set as the signal paths associated with the sensing target.

[0114] In an embodiment 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 parameter of the signal paths, and then uses the signal paths in the first set of signal paths that meet the first condition 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.

[0115] Optionally, the first configuration information is further used to indicate at least one of the following:

[0116] The first dimension;

[0117] The first condition;

[0118] Using the signal paths that meet the first condition as the signal paths associated with the sensing target;

[0119] The first parameter;

[0120] The second parameter;

[0121] The third parameter;

[0122] The first preset threshold;

[0123] The second preset threshold;

[0124] The third preset threshold.

[0125] The first specific interval range;

[0126] The second specific interval range.

[0127] For better understanding, the following takes the target signal as the first signal as an example to elaborate on the above several indicators and the determination of the signal paths associated with the sensing target in detail.

[0128] Calculation method of the first indicator:

[0129] The terminal performs channel estimation 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 indicator. 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 indicator.

[0130] Among them, the first dimension includes one of the following:

[0131] Time delay dimension;

[0132] Doppler dimension;

[0133] Azimuth angle dimension;

[0134] Elevation angle dimension;

[0135] Dimensions jointly formed by at least two of the time delay dimension, Doppler dimension, azimuth angle dimension, and elevation angle dimension. For example, time delay-Doppler dimension, time delay-Doppler-angle dimension, etc.

[0136] For example, if H(f) is the channel response, where f = 0, 1, 2, …, N - 1 represents frequency domain sampling points (such as subcarrier indices), then by performing an inverse Fourier transform on H(f), it can be transformed into the time delay dimension (the first dimension); also, for example, if H(f, t) is the channel response, where f = 0, 1, 2, …, N - 1 represents frequency domain sampling points (such as subcarrier indices) and t = 0, 1, 2, …, M - 1 represents time domain sampling points (such as OFDM symbol indices), then by performing an inverse Fourier transform along the frequency domain dimension and a Fourier transform along the time domain dimension on H(f, t), it can be transformed into the time delay-Doppler dimension (the first dimension); also, for example, if H(f, t, s) is the channel response, where f = 0, 1, 2, …, N - 1 represents frequency domain sampling points (such as subcarrier indices), t = 0, 1, 2, …, M - 1 represents time domain sampling points (such as OFDM symbol indices), and s = 0, 1, 2, …, P - 1 represents spatial domain sampling points (antenna indices or port indices), then 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), it can be transformed into the time delay-Doppler-angle dimension (the first dimension).

[0137] Among them, the method for determining the signal paths (briefly referred to as sensing paths) associated with the sensing target in the channel response measured for the first signal is as follows:

[0138] - Determine the first path set. The paths in the first path set (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 path set; where Figure 3 the horizontal axis represents the first dimension and the vertical axis represents the normalized amplitude);

[0139] - The paths (signal paths) associated with the sensing target are the paths in the first path set that satisfy the first condition.

[0140] Among them, the first condition includes at least one of the following:

[0141] · The Doppler of the path exceeds a first preset threshold or is within a first specific range;

[0142] · The time delay of the path exceeds a first preset threshold or is within a first specific range;

[0143] · The angle of the path exceeds a first preset threshold or is within a first specific range;

[0144] · The Doppler difference between the path and the first-arrival path (e.g., the line of sight (LOS) path) or the reference path (e.g., the signal path reflected by a specific target (e.g., a Reconfigurable Intelligent Surface (RIS) / Backscatter / other known passive targets, etc.)) exceeds a second preset threshold or is within a second specific range;

[0145] · The time delay difference between the path and the first-arrival path (e.g., the 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 a second preset threshold or is within a second specific range;

[0146] · The angle difference between the path and the first-arrival path (e.g., the 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 a second preset threshold or is within a second specific range.

[0147] Wherein, the above preset thresholds or specific ranges are sent by other devices to the receiving device, and are determined by other devices according to the perception prior information or perception requirements. Alternatively, the above preset thresholds or set ranges are determined by the receiving device according to the perception prior information or perception requirements.

[0148] For example, in Figure 1, paths 0, 1, 2, 3 are paths in the first path set, where paths 2, 3 are the perceived paths that meet the first condition (e.g., their time delays meet the preset threshold), and paths 0, 1 are the paths associated with other scatterers.

[0149] Wherein, the perception prior information or perception requirements include the following information:

[0150] · Sensing service or sensing service type. The sensing service may be, for example, detecting the presence of a target, 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, gait recognition, facial expression recognition, facial recognition, respiration 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, pedestrian or vehicle flow detection, crowd density / vehicle density detection, etc.; The sensing service type may 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 functions. 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.

[0151] · Sensing target area: It refers to the location area where the sensing object may exist, or the location area where imaging or environment reconstruction needs to be performed.

[0152] · Sensing object type: Classify the sensing objects according to their possible motion characteristics. Each sensing object type contains information such as the motion speed, motion acceleration, and typical RCS of typical sensing objects.

[0153] · Number of sensing targets.

[0154] Exemplarily, for frequency range 1, the reference point of the first metric may 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 by a certain receiving channel needs to be obtained by measuring the combined signals on multiple antenna elements corresponding to that receiving channel.

[0155] Optionally, the calculation method of the first metric may also be:

[0156] The power of the signal path associated with the sensing target in the first dimension and The difference is used as the first metric, where N1 Indicates the number of paths associated with the sensing target. Is the average power of multiple paths outside the first path set in the first dimension.

[0157] The received power of the first signal is calculated as follows:

[0158] 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.

[0159] Optionally, the calculation method of the received power of the first signal can also be:

[0160] The difference between the sum of the powers of all paths in the first path set in the first dimension and where N 2 Indicates 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.

[0161] The total received power is calculated as follows:

[0162] Total received power

[0163] The calculation method of the second indicator is as follows:

[0164] 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 based on H filter1 (k) and the first signal X(k), that is, Y filter1 (k) = H filter1 (k)X(k). Then the received signal Y(k) is subtracted from the received signal Y filter1 (k) after the first filtering process to obtain the interference and noise signal Y σ1 (k), that is, Y σ1 (k) = Y(k) - Y filtee1 (k), and then the second indicator is calculated

[0165] Among them, the first filtering process is used to eliminate noise, interference, and paths not associated with the sensing target in the first dimension. For example, the first filtering process sets the amplitudes of other paths except the paths associated with the sensing target in Figure 3 to zero. The channel response H filter1 (k) after the first filtering process does not contain noise, interference, and paths not associated with the sensing target, and only contains paths associated with the sensing target.

[0166] The calculation method of the third index is as follows:

[0167] The channel response H(k) is subjected to a second filtering process to obtain H filter2 (k), and then based on H filter2 (k) and the first signal X(k), the received signal Y filter2 (k) after the second filtering process is calculated, that is, Y filter2 (k) = H filter2 (k)X(k). Then the received signal Y(k) is subtracted from the received signal Y filter2 (k) after the second filtering process to obtain the interference and noise signal Y σ2 (k), that is, Y σ2 (k) = Y(k) - Y filter2 (k), and then the third index is calculated

[0168] The second filtering process can be a noise interference suppression process in the first dimension (for example Figure 3 setting the amplitudes of other paths except the first path set to zero), or a minimum mean square error (MMSE) filter. The channel response H filter2 (k) after the second filtering process does not contain noise and interference, and only contains the paths in the first path set.

[0169] Alternatively, the calculation method of the third index can also be:

[0170] Based on the average power of multiple paths outside the first path set in the first dimension calculate the third index P σ2 , that is where N represents the number of sampling points in the first dimension.

[0171] 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, then there are the following methods:

[0172] Method 1: Calculate the target index of each sensing target separately. For example, in Figure 3The paths associated with each sensing target are respectively determined, and then the target indicators corresponding to each sensing target are calculated respectively. At this time, 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)

[0173] 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 the virtual sensing target.

[0174] 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.

[0175] Step 202, the first device determines transmit power adjustment information according to the measured value of the target indicator.

[0176] Among them, the transmit power adjustment information is used to indicate the target transmit power of the second signal. It should be noted that the second signal can be a signal of the same type as the first signal, or in some scenarios, the second signal is also the first signal, and the transmit power adjustment information is also used to indicate the transmit power of the first signal at a subsequent transmission moment.

[0177] Optionally, the second signal can be a sensing signal, such as a dedicated signal for sensing services; or, the second signal can also be a communication signal, such as a reference signal, a synchronization signal, etc.

[0178] In the embodiments of the present application, the first device can obtain the measured value of the target indicator corresponding to the first signal transmitted at the first moment, and determine the transmit power adjustment information according to the measured value of the target indicator. For example, the transmit power adjustment information is the target transmit power of the second signal at the second moment. Exemplarily, the second signal can be a signal of the same type as the first signal, then the first device can determine the transmit power of the first signal at the second moment according to the measured value of the target indicator. Among them, the second moment is after the first moment.

[0179] Optionally, the first moment and the second moment may include multiple time points, such as the first signal transmitted on multiple OFDM symbols. In some embodiments, signal processing needs to be performed on the first signal on multiple OFDM symbols to obtain the target metric.

[0180] It should be noted that the beam direction or Quasi co-location (QCL) relationship between the first signal at the first moment and the second signal (or it can also be the first signal) at the second moment remains unchanged, that is, the transmission power is adjusted per beam.

[0181] In the embodiment of the present application, the first device obtains a measurement value of the target metric corresponding to the first signal, and further determines transmission power adjustment information according to the measurement value of the target metric, where the transmission power adjustment information is used to indicate the target transmission power of the second signal, and the target metric is related to the signal quality of the signal path associated with the sensing target. The first signal and the second signal can be sensing signals. Furthermore, the first device can adaptively adjust the transmission power of the sensing signal according to the target metric, that is, it clarifies how to determine the transmission power of the sensing signal in the integrated communication and sensing system, which helps to improve the adjustment effect of the device on the transmission power of the sensing signal to improve the sensing performance.

[0182] Optionally, the method further includes any one of the following:

[0183] The first device sends the transmission power adjustment information to the sending device of the first signal;

[0184] The first device sends the transmission power adjustment information to the sending device of the first signal through the sensing functional network element.

[0185] For example, the first device is a UE. The UE receives the first signal sent by the base station at the first moment, performs signal processing on the signal to obtain a measurement value of the target metric, determines the transmission power adjustment information according to the measurement value of the target metric, and further sends the transmission power adjustment information to the base station. Or, the UE sends the transmission power adjustment information to the sensing functional network element, and the sensing functional network element sends the transmission power adjustment information to the base station. Furthermore, the base station can determine the transmission power of the first signal at the second moment according to the transmission power adjustment information and perform the transmission of the first signal based on this transmission power. Thus, the base station can also determine the transmission power of the signal according to the transmission power adjustment information, which helps to ensure the sensing performance and optimize the system efficiency.

[0186] Optionally, the transmission power adjustment information includes at least one of the following:

[0187] The identity (ID) of the first signal;

[0188] The ID of the second signal;

[0189] The target transmit power, where the target transmit power is the transmit power of the second signal;

[0190] The difference between the target transmit power and the transmit power of the first signal;

[0191] The ratio of the target transmit power to the transmit power of the first signal;

[0192] The step value of the target transmit power and the transmit power of the first signal.

[0193] For example, in some embodiments, the first device knows the transmit power of the first signal at the first moment. The first device can directly determine the transmit power of the second signal (which can also be the first signal) at the second moment according to the measured value of the target metric.

[0194] In other embodiments, the first device does not need to know the transmit power of the first signal at the first moment. The first device can determine the difference or ratio or step value between the transmit power of the second signal (which can also be the first signal) at the second moment and the transmit power of the first signal at the first moment according to the measured value of the target metric. For example, according to the measured value of the target metric, the first device determines the difference between the transmit power of the first signal at the second moment and the transmit power of the first signal at the first moment, that is, the first device determines that the transmit power of the first signal at the second moment needs to be increased by several dB compared with the transmit power of the first signal at the first moment.

[0195] In the embodiments of the present application, the first device determines the transmit power adjustment information according to the measured value of the target metric, and then can determine the transmit power of the second signal at the second moment based on the transmit power adjustment information. Furthermore, it clarifies the method of determining the transmit power of the sensing signal in the integrated communication and sensing system, which helps to ensure the sensing performance and optimize the system efficiency.

[0196] Optionally, the first device obtains the measured value of the target metric corresponding to the first signal, including:

[0197] The first device determines the measured value of the target metric; or,

[0198] The first device obtains the measured value of the target metric determined by the second device.

[0199] Understandably, the first device may determine the measured value of the target metric itself; alternatively, 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.

[0200] Optionally, the first device determines the measured value of the target metric corresponding to the first signal, including any one of the following:

[0201] When the first device is the receiving 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;

[0202] When 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 metric according to the first measurement quantity.

[0203] That is, if the first device is the receiving 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 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 device of the first signal and determines the measured value of the target metric according to the first measurement quantity.

[0204] Among them, the first measurement quantity includes at least one of the following:

[0205] The first-level measurement quantity (such as the received signal / raw channel information), including: the received signal / channel response complex result, amplitude / phase, I / Q channels and their operation results, where the operations include addition, subtraction, multiplication, division, matrix addition, subtraction, multiplication, matrix transpose, triangular relationship operations, square root operations, and power operations, etc., as well as the threshold detection result, maximum or minimum extraction result, etc. of the above operation results; 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 operation, wavelet transform, and digital filtering, etc., as well as the threshold detection result, maximum / minimum extraction result, etc. of the above operation results;

[0206] 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, and intensity;

[0207] The third-level measurement quantities include: distance, speed, orientation, spatial position, acceleration, etc.;

[0208] 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.

[0209] 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:

[0210] The first device obtains second configuration information, and the second configuration information is used to indicate the measurement quantity type of the first measurement quantity.

[0211] It can be understood that if 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 measurement value of the target index according to the first measurement quantity. In this case, the first device can first obtain the second configuration information, and 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 more measurement quantities the first measurement quantity is, and then the first device can also clearly determine which one or more measurement quantities to use to determine the measurement value of the target index, so as to ensure that the first device can determine the transmit power adjustment information according to the measurement value of the target index.

[0212] Optionally, the first device obtains the second configuration information, including at least one of the following:

[0213] The first device obtains at least part of the information in the second configuration information sent by the sensing function network element;

[0214] The first device obtains at least part of the information in the second configuration information based on protocol agreements.

[0215] For example, the second configuration information is used to indicate which two measurement quantities the first measurement quantity includes. The types of these two measurement quantities can be sent by the sensing function network element, or the types of these two measurement quantities can be those that must be obtained according to protocol agreements, or one of the measurement quantities is those that must be obtained according to protocol agreements, and the other measurement quantity is sent by the sensing function network element. In this way, it also 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.

[0216] Optionally, in the embodiments of the present application, the first device determines transmit power adjustment information according to the measured value of the target metric, including at least one of the following:

[0217] The first device determines transmit power adjustment information according to the measured value of the target metric corresponding to the first signal and a first value, so that the target value of the target metric corresponding to the second signal is the first value;

[0218] The first device determines transmit power adjustment information according to the measured value of the target metric corresponding to the first signal and a fourth preset threshold, so that the target value of the target metric corresponding to the second signal is greater than or equal to the fourth preset threshold;

[0219] The first device determines transmit power adjustment information according to the measured value of the target metric corresponding to the first signal and a fifth preset threshold, so that the target value of the target metric corresponding to the second signal is less than or equal to the fifth preset threshold.

[0220] For example, in one implementation, the target metric is the received power of the signal path associated with the sensed target. The received power of the signal path associated with the sensed 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 sensed 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 transmit power adjustment information can be determined to be 5 dB, so that the received power of the signal path associated with the sensed target corresponding to the second signal at the second moment is -80 dBm.

[0221] In another implementation, the target metric is the sensed SINR, and the fourth preset threshold is 10 dB. Then the adjustment target of the transmit power is that the sensed SINR corresponding to the second signal needs to be 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 transmit power adjustment value should be greater than or equal to 4 dB, that is, the transmit power adjustment information is greater than or equal to 4 dB.

[0222] In yet another implementation, the target metric is the sensed SINR, and the fifth preset threshold is 20 dB. Then the adjustment target of the transmit power is that the sensed SINR corresponding to the second signal needs to be less than or equal to 20 dB (i.e., the fifth preset threshold is 20 dB) to avoid waste of transmit power resources. If the sensed SINR of the first signal measured at the first moment is 23 dB, the transmit power adjustment value should be less than or equal to -3 dB, that is, the transmit power adjustment information is less than or equal to -3 dB.

[0223] In an embodiment of the present application, the first device can determine transmission power adjustment information based on the measured value of the target metric corresponding to the first signal and a first value or a preset threshold, so that the target value of the target metric corresponding to the second signal meets a preset first value or a preset threshold, thereby enabling better adjustment of the transmission power to ensure sensing performance and optimize system efficiency.

[0224] Optionally, before determining the transmission power adjustment information, the method further includes:

[0225] The first device obtains third configuration information, which is used to indicate at least one of the following:

[0226] The target value of the target metric corresponding to the second signal is a first value;

[0227] The first value;

[0228] The target value of the target metric corresponding to the second signal is greater than or equal to a fourth preset threshold;

[0229] The fourth preset threshold;

[0230] The target value of the target metric corresponding to the second signal is less than or equal to a fifth preset threshold;

[0231] The fifth preset threshold.

[0232] It can be understood that before determining the transmission power adjustment information, the first device first obtains the third configuration information, so that the first device can determine the conditions (the first value or the fourth preset threshold or the fifth preset threshold) that the target value of the target metric corresponding to the second signal needs to meet according to the above content indicated by the third configuration information, which helps the first device better determine the transmission power adjustment information, that is, determine the adjustment range of the transmission power.

[0233] Optionally, the first device obtaining the third configuration information includes at least one of the following:

[0234] The first device obtains at least part of the information in the third configuration information sent by the sensing function network element;

[0235] The first device obtains at least part of the information in the third configuration information based on protocol agreements.

[0236] 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 functional network element, or these two pieces of information content can be those that must be obtained by protocol agreement, or one of the information content is those that must be obtained by protocol agreement, and the other information content is sent by the sensing functional network element. In this way, the first device can better determine the transmit power adjustment information based on the third configuration information.

[0237] For better understanding, the method provided in this application will be explained below through several specific embodiments.

[0238] Embodiment 1:

[0239] In this embodiment, the first device is the receiving end device of the first signal.

[0240] At the first moment, the first device receives the first signal and determines the measured value of the target indicator indicated by the first configuration information according to the first configuration information. According to the measured value of the target indicator, the first device combines the information content indicated by the third configuration information to determine whether it is necessary to adjust the transmit power of the first signal.

[0241] When the first device determines that it is necessary to adjust the transmit power of the first signal, the first device further determines the transmit power adjustment information, and then includes any of the following steps:

[0242] The first device sends the transmit power adjustment information to the sending end device of the first signal;

[0243] The first device sends the transmit power adjustment information to the sensing functional network element, and the sensing functional network element sends it to the sending end device of the first signal;

[0244] In the self-transmitting and self-receiving sensing mode, the first device is also the sending end device of the first signal, then the first device does not need to send the transmit power adjustment information.

[0245] In a typical implementation manner, the base station sends the first signal, and the UE receives the first signal to perform sensing.

[0246] At the first moment, the UE receives the first signal and determines the measured value of the target indicator. According to the measured value of the target indicator, the UE determines whether it is necessary to adjust the transmit power of the first signal: including: whether it is necessary to increase the transmit power, whether it is possible to reduce the transmit power; when the UE determines that it is necessary to adjust the transmit power of the first signal, the UE determines the transmit power adjustment information. The process for the UE to make the above determination and determine the transmit power adjustment information can include the following steps:

[0247] (1) The UE compares the measured value of the target metric with a first value to obtain a difference value between the measured value of the target metric and the first value (including at least one of: the difference of linear values, the ratio of linear values, the difference of logarithmic values (dB)); based on the difference value, the UE determines the transmit power adjustment information.

[0248] For example: The target metric is the received power of the signal path associated with the sensing target (i.e., the first metric), and the first value is a value specified by the protocol or configured by the sensing function network element. If the measured value (logarithmic value) of the target metric is smaller than the first value (logarithmic value) by X dB, then the transmit power should be increased by X dB. Based on this, the transmit power adjustment information can be determined, including the following optional steps:

[0249] (a1) The transmit power adjustment information can directly be X dB;

[0250] (a2) The transmit power adjustment information can be a value not less than X dB among the preconfigured transmit power adjustment step values; for example, if X dB is 5 dB and the transmit power adjustment step value is 3 dB, then the transmit power adjustment information can be to adjust 2 step values (corresponding to 6 dB);

[0251] (a3) The transmit power adjustment information can be a value not less than the transmit power at the first moment + X dB or its corresponding index among the preconfigured transmit power candidate values; for example, the preconfigured transmit power candidate values include values such as {…12 dBm, 15 dBm, 18 dBm…}, the transmit power at the first moment is 12 dBm, and X dB is 5 dB, then the transmit power adjustment information should be a value not less than 17 dBm among the candidate values. In this example, the transmit power adjustment information is 18 dBm or its corresponding index.

[0252] (2) The UE compares the measured value of the target metric with a fourth preset threshold. If the measured value of the target metric is greater than or equal to the fourth preset threshold, there is no need to adjust the transmit power. If the measured value of the target metric is less than the fourth preset threshold, then the UE determines the transmit power adjustment information based on the difference value between the measured value of the target metric and the fourth preset threshold (including at least one of: the difference of linear values, the ratio of linear values, the difference of logarithmic values (dB)).

[0253] For example: The target metric is the received power of the signal path associated with the sensing target (i.e., the first metric), and the fourth preset threshold is a value specified by the protocol or configured by the sensing function network element. If the measured value (logarithmic value) of the target metric is smaller than the fourth preset threshold (logarithmic value) by X dB, then the transmit power should be increased by X dB. Based on this, the transmit power adjustment information can be determined, including the following optional steps:

[0254] (b1) The transmit power adjustment information can directly be X dB;

[0255] (b2) The transmit power adjustment information can be a value not less than X dB among the pre-configured transmit power adjustment step values; for example, if X dB is 5 dB and the transmit power adjustment step value is 3 dB, then the transmit power adjustment information can be to adjust 2 step values (corresponding to 6 dB);

[0256] (b3) The transmit power adjustment information can be a value among the pre-configured transmit power candidate values that is not less than the transmit power at the first moment + X dB; for example, the pre-configured transmit power candidate values include {…12 dBm, 15 dBm, 18 dBm…} and other values, the transmit power at the first moment is 12 dBm, and X dB is 5 dB, then the transmit power adjustment information should be a value not less than 17 dBm among the candidate values. In this example, the transmit power adjustment information is 18 dBm.

[0257] (3) The UE compares the measured value of the target metric with the fifth preset threshold. If the measured value of the target metric is less than or equal to the fifth preset threshold, there is no need to adjust the transmit power. If the measured value of the target metric is greater than the fifth preset threshold, the UE determines the transmit power adjustment information according to the difference value between the measured value of the target metric and the fifth preset threshold (including at least one of: the difference of linear values, the ratio of linear values, and the difference of logarithmic values (dB)).

[0258] For example: The target metric is the received power of the signal path associated with the sensing target (i.e., the first metric), and the fifth preset threshold is a value agreed upon according to the protocol or configured by the sensing functional network element. If the measured value (logarithmic value) of the target metric is X dB greater than the fifth preset threshold (logarithmic value), the transmit power can be reduced by X dB. Based on this, the transmit power adjustment information can be determined, including the following optional steps:

[0259] (c1) The transmit power adjustment information can directly be -X dB;

[0260] (c2) The transmit power adjustment information can be a value not less than -X dB among the pre-configured transmit power adjustment step values; for example, if X dB is -5 dB and the transmit power adjustment step value is 3 dB, then the transmit power adjustment information can be to adjust 2 step values (corresponding to -6 dB);

[0261] (c3) The transmit power adjustment information may be a value among the pre-configured transmit power candidate values that is not greater than the transmit power at the first moment - X dB. For example, if the pre-configured transmit power candidate values include {…12 dBm, 15 dBm, 18 dBm…} and the transmit power at the first moment is 18 dBm and X dB is -5 dB, then the transmit power adjustment information should be a value among the candidate values that is not greater than 13 dBm. In this example, the transmit power adjustment information is 12 dBm.

[0262] After the UE determines the transmit power adjustment information, it sends the transmit power adjustment information to the base station.

[0263] Embodiment 2:

[0269] The first device receives the measured value of the target metric from the receiving-end device of the first signal. Before this, the receiving-end device of the first signal needs to obtain the first configuration information from the sensing function network element.

[0270] (2) The first device receives the first measurement quantity indicated by the second configuration information, determines the measured value of the target metric based on the first measurement quantity, and further determines the transmit power adjustment information.

[0273] The first device receives the first measurement quantity from the receiving-end device of the first signal. Before this, the receiving-end device of the first signal needs to obtain the second configuration information from the sensing function network element.

[0275] At the first moment, the UE receives a first signal and determines a measured value of a target metric. Then, the UE reports the measured value of the target metric to the base station.

[0276] After obtaining the measured value of the target metric, the base station adjusts the transmission power based on the implementation without sending the transmission power adjustment information.

[0283] Prior to this, the receiving end device of the first signal needs to obtain the second configuration information from the sensing functional network element.

[0284] In a typical implementation, base station A receives a first signal, and the first signal may be sent by base station A, base station B, or the UE to perform a sensing service.

[0285] At the first moment, base station A receives the first signal, obtains a first measurement quantity, and sends the first measurement quantity to the sensing functional network element. The sensing functional network element calculates the measured value of the target metric based on the first measurement quantity.

[0286] Then, the sensing functional network element sends the measured value of the target metric to base station A, base station B, or the UE, and base station A, base station B, or the UE makes subsequent judgments and adjusts the transmission power.
