[0047] ISAC has attracted great research interest and attention from academia and industry.

[0048] Specifically, the integrated low-cost implementation of communication and perception dual functions can be achieved through hardware device sharing and software-defined functions. Its main features are: first, the architecture is unified and simplified; second, the functions are reconfigurable and scalable; and third, efficiency is improved and cost is reduced.

[0049] The advantages of integrated communication and perception are mainly in three aspects: first, reduced equipment costs and size; second, improved spectrum utilization; and third, improved system performance.

[0050] The following table shows typical scenarios of integrated communication and perception that are expected to be achieved through technical upgrades based on the 5G communication system architecture.

[0061] Base station A or base station B may also be referred to as a radio access network (RAN) device, a radio access network function, or a radio access network unit.

As long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0063] As shown in Figure 1, there are six basic sensing modes, depending on the different sensing signal sending and receiving nodes. These modes are:

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

[0065] (2) Air interface sensing between base stations: Base station B receives the sensing signal sent by base station A and performs sensing measurements.

[0070] It's worth noting that each sensing method in the figure uses one sensing signal transmitting node and one sensing signal receiving node as examples. In actual systems, one or more sensing methods can be selected based on different sensing use cases and requirements, and each sensing method can have one or more transmitting and receiving nodes. The sensing targets in the figure use people and vehicles as examples, assuming that neither person nor vehicle carries or has installed signal transmitting / receiving equipment. In actual scenarios, the sensing targets will be much richer.

[0071] However, in the synaesthesia integration technology, there may be problems such as poor perception performance of the perception signal or low system efficiency.

[0072] In view of this, an embodiment of the present application provides a signal configuration method that enables the first device to adaptively adjust the first configuration information used to configure or expected by the first device for configuring the first signal based on the measured value of the target indicator, thereby ensuring the perceptual performance of the perception service and improving system efficiency. For example, when the measured value of the target indicator indicates that the perceptual quality is poor, the number of time-frequency resources occupied by the perception signal can be increased through the first configuration information to improve the perceptual quality; conversely, when the measured value of the target indicator indicates that the perceptual quality is good, the number of time-frequency resources occupied by the perception signal can be reduced through the first configuration information to reduce the time-frequency resource overhead.

[0073] The signal configuration method provided in the embodiments of the present application is described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0074] FIG2 is a schematic flowchart of a signal configuration method 210 according to an embodiment of the present application.

[0075] S211: The first device obtains a measurement value of a target indicator.

[0076] Exemplarily, the target indicator is used to reflect perceived signal quality of perception performed according to the first signal.

[0077] Exemplarily, the measurement value of the target indicator is obtained by performing signal processing on the first signal on the target resource and / or other signals on other resources to obtain the measurement value of the target indicator. Exemplarily, the target resource is a time domain resource unit, a frequency domain resource unit, or a time-frequency domain resource unit that carries the first signal. The time domain resource unit may be one or more orthogonal frequency division multiplexing (OFDM) symbols, the frequency domain resource unit may be one or more subcarriers, and the time-frequency domain resource unit may be one or more resource elements (RE), for example, one RE occupies 1 subcarrier in the frequency domain and 1 OFDM symbol in the time domain. Exemplarily, the other resources may be resources configured by high-layer signaling. Exemplarily, the first signal may be a perception signal, such as a dedicated signal for perception services; or the first signal may be a communication signal, such as a reference signal, a synchronization signal, or other signals used for communication.

[0078] Exemplarily, the measured value of the target indicator may be a value determined based on the total received power. The total received power refers to the linear average of the total received power on the target resource, or the total received power refers to the product of the received signal strength indicator (RSSI) measured on the target resource or other resources and a preset coefficient.

[0079] Exemplarily, the measured value of the target indicator is measured based on a first signal at a first moment.

[0080] S212: The first device determines first configuration information or a first index based on the measured value of the target indicator, where the first index is used by the second device to determine the first configuration information.

[0081] The first configuration information is used to configure the first signal, or the first configuration information is configuration information expected by the first device for configuring the first signal.

[0082] Exemplarily, the first configuration information is used to configure the time-frequency resources of the first signal at the second moment, or the first configuration information is information that the first device expects to use to configure the time-frequency resources of the first signal at the second moment. The second moment is after the first moment. The first moment or the second moment may include multiple time points, such as multiple OFDM symbols. In some embodiments, signal processing is required for the first signal on multiple OFDM symbols to obtain the measured value of the target indicator.

[0083] Exemplarily, the first index is used to indicate the number of time-frequency resources or the adjustment amount of the number of time-frequency resources of the first signal at the second moment.

[0084] Exemplarily, if the first device expects configuration information for configuring the first signal, the first configuration information may include the number of time-frequency resources expected by the first device for configuring the first signal, for example, including but not limited to at least one of the following: the time domain density of the first signal, the frequency domain density of the first signal, and the bandwidth of the first signal.

[0085] In some embodiments (see Example 2-1), the first device is a base station. After the base station measures the measurement value of the target indicator, it can directly determine the time-frequency resource configuration of the first signal at the second moment, that is, the first configuration information. The first configuration information is used to configure the first signal.

[0086] In some implementations (see Example 2-2), the first device is a base station and the second device is a UE. After the UE obtains the measured value of the target indicator, it may have the following options:

[0087] The UE (second device) reports the measured value of the target indicator to the base station (first device), and then the base station ((first device) determines the first configuration information, where the first configuration information is used to configure the first signal, and then adjust the time-frequency resources of the first signal.

[0088] The UE selects an index (i.e., a first index) from the mapping relationship information based on the pre-configured mapping relationship information and the measured value of the target indicator, and reports the first index to the base station to recommend to the base station how to adjust the time-frequency resources of the first signal. The base station may accept the UE's recommendation or not. If the base station accepts the UE's recommendation, the base station determines the first configuration information in combination with the first index, and the first configuration information is used to configure the first signal, thereby adjusting the time-frequency resources of the first signal.

[0089] In this embodiment, the first device determines the first configuration information or the first index based on the measured value of the target indicator, so that the first device can adaptively adjust the first configuration information used for configuration or the first configuration information expected by the first device for configuring the first signal based on the measured value of the target indicator, thereby ensuring the perception performance of the perception service and improving the system performance.

[0090] It should be understood that if the first configuration information is used to configure the first signal, the first configuration information may also be referred to as signal configuration information, and the signal configuration information includes at least one of the following:

[0092] Subcarrier spacing: For example, the subcarrier spacing of the OFDM system is 30KHz;

[0093] Guard interval: The time interval between the moment a signal ends sending and the moment the latest echo signal of the signal is received; this parameter is proportional to the maximum sensing distance; for example, it can be measured by 2d max / c calculated, d max is the maximum sensing distance (belongs to the sensing requirement), for example, for the self-transmitted and self-received sensing signal, d max Represents the maximum distance between the perceived signal receiving and transmitting point and the signal transmitting point. In some cases, the OFDM signal cyclic prefix (CP) can serve as the minimum guard interval.

[0094] Bandwidth: This parameter is inversely proportional to the range resolution and can be obtained by c / (2Δd), where Δd is the range resolution (perception requirement) and c is the speed of light.

[0095] Burst duration: This parameter is inversely proportional to the rate resolution (a perception requirement). It is the time span of the perception signal, mainly for calculating the Doppler frequency deviation. This parameter can be calculated by c / (2f c Δv) is calculated; where Δv is the velocity resolution; f c is the carrier frequency of the sensing signal;

[0096] Time domain interval: This parameter can be expressed by c / (2f c v range ) is calculated; where v range It is the maximum rate minus the minimum speed (belonging to the perception requirement); this parameter is the time interval between two adjacent perception signals;

[0097] Transmit signal power, for example, from -20dBm to 23dBm, with a value of 2dBm;

[0099] Signal direction; for example, sensing the direction of the signal or beam information;

[0100] Time resources, such as the time slot index or symbol index of the time slot where the perception signal is located. There are two types of time resources: one is a one-time time resource, for example, one symbol sends an omnidirectional perception signal; the other is a non-one-time time resource, such as multiple groups of periodic time resources or discontinuous time resources (which may include start time and end time). Each group of periodic time resources sends a perception signal in the same direction, and different groups of periodic time resources have different beam directions.

[0101] Frequency resources, including the center frequency of the perception signal, bandwidth, resource block (RB) or subcarrier, point A, starting bandwidth position, etc.

For example, the bitmap uses "1" to indicate that the element is selected for sending and / or receiving sensing signals, and "0" to indicate that the element is not selected (or vice versa). Bitmap information of array panels. For example, the bitmap uses "1" to indicate that the panel is selected for sending and / or receiving sensing signals, and "0" to indicate that the element is not selected (or vice versa). As well as the element bitmap information within these selected panels;

The threshold value may be different for different candidate nodes and / or candidate tags. For any candidate node and / or candidate tag, the perception measurement value and its corresponding threshold value may be greater than one.

[0120] The target resource is a time domain resource unit, a frequency domain resource unit, or a time-frequency domain resource unit that carries the first signal; the total received power refers to the linear average value of the total received power on the target resource, or the product of the received signal strength indication RSSI measured on the target resource or other resources and a preset coefficient.

[0121] Exemplarily, the time domain resource unit may be one or more OFDM symbols, the frequency domain resource unit may be one or more subcarriers, and the time-frequency domain resource unit may be one or more REs. For example, one RE occupies one subcarrier in the frequency domain and one OFDM symbol in the time domain.

[0122] Exemplarily, the other resources may be resources configured by higher-layer signaling.

[0123] Exemplarily, the first signal may be a perception signal, such as a dedicated signal for perception services; or the first signal may be a communication signal, such as a reference signal, a synchronization signal, or other signal used for communication.

[0124] Exemplarily, the path associated with the perception target refers to the path associated with the perception target.

[0125] In this embodiment, by defining a target indicator, it is helpful to improve the effect of the first device adaptively adjusting the first configuration information used to configure or expected by the first device for configuring the first signal based on the measured value of the target indicator. In other words, the method for link adaptive adjustment of the time-frequency resources of the perception signal is improved, thereby improving the adjustment effect of the link adaptive adjustment of the time-frequency resources of the perception signal, thereby ensuring the perception performance of the perception service and improving system performance.

[0126] In some embodiments, the method 210 further includes:

[0127] The first device performs channel estimation based on the first signal and a received signal corresponding to the first signal to obtain a channel response;

[0128] The first device transforms the channel response into a first dimension;

[0129] The first device determines, among the paths corresponding to the first dimension, the path associated with the perception target;

[0130] The first dimension includes at least one of the following:

[0131] Delay dimension;

[0132] Doplevi;

[0133] Azimuth dimension;

[0134] Pitch angle dimension.

[0135] Exemplarily, the first device performs channel estimation based on the transmitted first signal X(k) and the received signal Y(k) corresponding to the first signal to obtain a channel response (Channel Response) H(k) = Y(k) / X(k), where k = 0, 1, 2, ..., K-1 represents a resource unit index. After obtaining the channel response H(k), the first device transforms it into a first dimension and determines a path associated with the perception target from the path corresponding to the first dimension.

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

[0137] In some embodiments, the first device determines the path associated with the perception target in the path corresponding to the first dimension, which can be implemented as follows:

[0139] The first condition includes at least one of the following:

[0140] The first parameter of the path exceeds a first threshold value or is within a first specific interval;

[0141] The difference between the first parameter of the first path and the first path or the reference path exceeds a second threshold value or is within a second specific interval;

[0142] The second parameter of the path satisfies the preset modulation rule;

[0143] Wherein, the first parameter includes at least one of the following: amplitude, power, intensity, energy, Doppler, delay, angle;

[0144] The second parameter includes at least one of the following: amplitude, power, intensity, energy, and phase.

[0145] Exemplarily, different first parameters correspond to different values ​​of the first threshold value or the value of the first specific interval range.

[0146] For example, the first condition includes at least one of the following:

[0149] The angle of the path exceeds the preset threshold corresponding to the angle or is within the specific interval range corresponding to the angle;

[0150] The Doppler difference between the first arrival 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)) exceeds a preset threshold corresponding to the Doppler or is within a specific range corresponding to the Doppler;

[0151] The delay difference between the signal path and the first arrival path (e.g., LOS path) or the reference path (e.g., the signal path reflected by a specific target (e.g., RIS / backscatterer / other known passive target)) exceeds the preset threshold corresponding to the delay or is within the specific interval corresponding to the delay;

[0152] The angular difference between the signal path and the first arrival path (e.g., LOS path) or the reference path (e.g., the signal path reflected by a specific target (e.g., RIS / backscatterer / other known passive targets, etc.)) exceeds a preset threshold corresponding to the angle or is within a specific range corresponding to the angle.

[0153] In some embodiments, the first device determines, among the paths corresponding to the first dimension, a path that satisfies a first condition as the path associated with the perception target, which may be implemented as follows:

[0154] The first device determines a first path set among the paths corresponding to the first dimension, and a third parameter of each path in the first path set exceeds a third threshold value, and the third parameter includes at least one of the following: amplitude, power, intensity, and energy; the first device determines, in the first path set, a path that meets the first condition as the path associated with the perceived target.

[0155] Exemplarily, the paths in the first path set include the paths whose strength / power / energy exceeds a third threshold value among all the paths after the channel response is transformed into the first dimension.

[0156] It should be noted that the result of determining the path associated with the perception target according to the above method may be that there is no path associated with the perception target. In this case, it can be understood that the perception target is not detected or perceived. In this case, there is no measurement value of the target indicator. At this time, the first device can also determine the first configuration information or the first index. The specific method can be the same as the embodiment below, by increasing the number of time-frequency resources or other methods to determine the first configuration information or the first index.

[0157] Exemplarily, in the case where there is no path associated with the perception target, the first configuration information determined by the first device or the first configuration information associated with the first index has a number of time-frequency resources increased by a preset value compared to the second configuration information.

[0200] If the target device is not a perception function network element, the target device receives the second information from the perception function network element;

[0201] The target device obtains the second information agreed upon by the protocol.

[0202] In some embodiments, the S212 includes at least one of the following:

[0203] The first device adjusts the second configuration information by increasing or decreasing the number of time domain resources in the second configuration information based on the measured value of the target indicator, to obtain the first configuration information or the first index;

[0204] The first device adjusts the second configuration information by increasing or decreasing the number of frequency domain resources in the second configuration information based on the measured value of the target indicator, to obtain the first configuration information or the first index;

[0205] The second configuration information is configuration information of the first signal used to obtain the measurement value of the target indicator.

[0206] Exemplarily, the first configuration information may include at least one of the following changes compared to the second configuration information:

[0207] The increase in the number of time domain resources, i.e., the increase in the number of OFDM symbols occupied by the first signal, further includes at least one of the following: an increase in the time domain span of the first signal, i.e., an increase in the time span from the first OFDM symbol occupied by the first signal to the last OFDM symbol occupied by the first signal; an increase in the time domain density of the first signal, i.e., a decrease in the time interval between two adjacent OFDM symbols in the OFDM symbols occupied by the first signal.

[0208] Reduction in the number of time domain resources: that is, reduction in the number of OFDM symbols occupied by the first signal; further including at least one of the following: reduction in the time domain span of the first signal, that is, reduction in the time span from the first OFDM symbol occupied by the first signal to the last OFDM symbol; reduction in the time domain density of the first signal, that is, increase in the time interval between two adjacent OFDM symbols in the OFDM symbols occupied by the first signal.

[0210] Reduction in the number of frequency domain resources: i.e., reduction in the number of subcarriers occupied by the first signal. Further includes at least one of the following: reduction in the bandwidth of the first signal, i.e., reduction in the bandwidth from the first subcarrier to the last subcarrier occupied by the first signal; or reduction in the frequency domain density of the first signal, i.e., increase in the frequency domain spacing between two adjacent subcarriers occupied by the first signal.

[0211] In some embodiments, the beam direction associated with the first configuration information is the same as the beam direction associated with the second configuration information, or the quasi-co-site QCL relationship associated with the first configuration information is the same as the QCL relationship associated with the second configuration information. In other words, the first device may adjust the time-frequency resource configuration of the first signal on a per-beam basis.

[0212] In some embodiments, the S212 includes at least one of the following:

[0213] The first device determines the first configuration information or the first index according to the measured value and the target value of the target indicator, so that a measured value obtained when the target indicator is measured after the first signal is configured using the first configuration information is the target value;

[0214] The first device determines the first configuration information or the first index according to the measured value of the target indicator and the fourth threshold value, so that a measured value obtained when the target indicator is measured after the first signal is configured using the first configuration information is greater than or equal to the fourth threshold value;

[0215] The first device determines the first configuration information or the first index based on the measured value of the target indicator and the fifth threshold value, so that the measured value obtained when the first signal is configured to measure the target indicator using the first configuration information is less than or equal to the fifth threshold value.

[0216] Exemplarily, the target value is a measured value obtained when the target indicator is measured after the first signal is configured using the first configuration information. The fourth threshold value is a threshold value that the measured value obtained when the target indicator is measured after the first signal is configured using the first configuration information is greater than or equal to. The fifth threshold value is a threshold value that the measured value obtained when the target indicator is measured after the first signal is configured using the first configuration information is less than or equal to.

[0217] Exemplarily, the method by which the first device determines the first configuration information according to the measured value of the target indicator may be at least one of the following:

[0218] Make the value of the target indicator at the second moment the target value;

[0219] For example, the measured value of the target indicator (see Example 1) is the received power of the path associated with the perception target, and the target value is -80dBm. However, the received power of the path associated with the perception target measured at the first moment is -85dBm. In this case, the number of time-frequency resources of the first signal is increased so that the measured value of the target indicator at the second moment is increased by 5dB.

[0220] Make the target indicator at the second moment greater than or equal to a fourth threshold value;

[0221] For example, if the measured value of the target indicator (see Example 1) is the perceived SINR, and the fourth threshold value is 10 dB, the adjustment target of the transmit power is to make the perceived SINR at the second moment greater than or equal to 10 dB. If the perceived SINR measured at the first moment is 6 dB, the number of time-frequency resources of the first signal is increased so that the target indicator at the second moment is improved by at least 4 dB.

[0222] Make the target indicator at the second moment less than or equal to the fifth threshold value;

[0223] For example, if the measured value of the target indicator (see Example 1) is the perceived SINR, and the fifth threshold value is 20dB, then the adjustment target of the time-frequency resources is to make the perceived SINR at the second moment less than or equal to 20dB to avoid wasting time-frequency resources. For example, if the perceived SINR measured at the first moment is 23dB, the time-frequency resources of the first signal should be reduced so that the target indicator at the second moment is reduced by at least 3dB. It should be noted that when reducing the number of time-frequency resources of the first signal, the time-frequency resource configuration of the first signal should be maintained to meet the following requirements in the perception requirements: delay resolution requirement, maximum unambiguous measurement range requirement of delay, Doppler resolution requirement, and maximum unambiguous measurement range requirement of Doppler.

[0225] The first device obtains third information from the perception function network element; or

[0226] The first device obtains third information agreed upon by the protocol;

[0227] The third information includes at least one of the following information: the target value, the fourth threshold value, and the fifth threshold value.

[0228] Exemplarily, before the first device determines the first configuration information, the first device needs to receive third information, where the third information is used to indicate an adjustment method for determining the number of time-frequency resources of the first signal and a corresponding threshold value or preset range, that is, the third information includes at least one of the following:

[0231] An indication that the measured value of the target indicator at the second moment is lower than a fifth threshold value, and an indication of the fifth threshold value.

[0232] In some embodiments, the first device determines the first index based on the measured value of the target indicator, which may be implemented as follows:

[0233] The first device determines, as the first index, an index in the first mapping relationship information corresponding to the first configuration information; or

[0234] The first device determines the index corresponding to the interval where the measurement value of the target indicator is located in the second mapping relationship information as the first index.

[0237] The first device obtains fourth information agreed upon by the protocol;

[0238] The fourth information includes at least one of the following information: the first mapping relationship information and the second mapping relationship information.

[0239] Exemplarily, assuming that the first device is a UE and the second device is a base station, before the base station receives the first index from the UE, it needs to send the first mapping relationship information or the second mapping relationship to the UE.

[0240] In some embodiments, the first index is used to indicate at least one of the following:

[0241] The number of time domain resources, the number of frequency domain resources, the product of the number of time domain resources and the number of frequency domain resources, pre-configured time domain resources, pre-configured frequency domain resources, pre-configured time-frequency resources, and the interval range to which the measured value of the target indicator belongs.

[0249] The range of the target indicator's measurement value.

[0250] In some embodiments, the first configuration information is used to configure the first signal; the method 210 further includes:

[0251] The first device performs at least one of the following:

[0252] The first device sends part or all of the first configuration information to the second device;

[0259] The base station sends deactivation indication information to the terminal, where the deactivation indication information is used to instruct deactivation of one or more resource sets in the third configuration information.

[0260] Exemplarily, when the first device is a base station, after determining first configuration information, where the first configuration information is used to configure the first signal, the first device may perform a first operation, which includes at least one of the following operations:

[0261] The first device sends at least part of the first configuration information to the second device.

[0262] For example, if only the time domain resources of the first signal are adjusted, only the content related to the time domain resource configuration in the first configuration information needs to be sent. In a typical embodiment, using CSI-RS as the first signal, according to the above method, it is necessary to increase the number of time-frequency resources of the first signal, specifically to increase the time domain density of the first signal, for example, adjusting the time domain period of the CSI-RS from 8 time slots to 4 time slots, that is, modifying the CSI-ResourcePeriodicityAndOffset parameter.

[0263] The first device sends an activation instruction to the second device, where the activation instruction is used to activate one or more resource sets in third configuration information, where the one or more resource sets or resources in the third configuration information are not used to perform the sensing service before the adaptive adjustment of the sensing signal configuration is performed, but are used to perform the sensing service after the adaptive adjustment of the sensing signal configuration is performed.

[0267] Exemplarily, the third configuration information, including multiple resource sets or resources, needs to be configured to the second device by the base station or the perception function network element before executing the above steps.

[0268] In this embodiment, by introducing the third configuration information, the first device can directly implement adaptive adjustment of the perception signal configuration through an activation instruction or a deactivation instruction, thereby reducing the resources consumed and the adjustment efficiency when adjusting the perception signal configuration.

[0269] In some embodiments, the first configuration information is configuration information expected by the first device for configuring the first signal, and the method 210 further includes:

[0272] Exemplarily, the first device sends updated part or all of the information in the first configuration information, or the first index to the second device.

[0273] Exemplarily, the first indication information is used to indicate that the second device accepts the first configuration information or the first index, which can be understood as: the second device accepts the first configuration information as the configuration information of the first signal, or the second device accepts the first configuration information determined based on the first index as the configuration information of the first signal.

[0274] Exemplarily, when the first device is a UE, after determining the first index, the UE sends the first index to the base station. The base station determines first configuration information based on the first index, where the first configuration information is used to configure the first signal. Thereafter, the first device may perform a second operation, which includes at least one of the following operations:

[0275] The second device sends at least part of the first configuration information to the first device.

[0276] For example, if only the time domain resources of the first signal are adjusted, only the content related to the time domain resource configuration in the first configuration information needs to be sent. In a typical embodiment, using CSI-RS as the first signal, according to the above method, it is necessary to increase the number of time-frequency resources of the first signal, specifically to increase the time domain density of the first signal, for example, adjusting the time domain period of the CSI-RS from 8 time slots to 4 time slots, that is, modifying the CSI-ResourcePeriodicityAndOffset parameter.

[0277] The second device sends an activation instruction to the first device, where the activation instruction is used to activate one or more resource sets in the third configuration information, where the one or more resource sets or resources in the third configuration information are not used to perform the sensing service before the adaptive adjustment of the sensing signal configuration is performed, but are used to perform the sensing service after the adaptive adjustment of the sensing signal configuration is performed;

[0278] The second device sends a deactivation instruction to the first device, where the deactivation instruction is used to deactivate one or more resource sets or resources in the third configuration information, where the one or more resource sets or resources in the third configuration information are used to perform the perception service before performing the adaptive adjustment of the perception signal configuration, but are not used to perform the perception service after performing the adaptive adjustment of the perception signal.

[0279] The second device sends first indication information to the first device, which is used to indicate that the base station has accepted the time-frequency resource configuration recommended by the UE (ie, accepted the first configuration information, or determined the first configuration information by the first index).

[0343] The signal configuration method provided in this application is described below with reference to specific embodiments.

[0344] Example 1:

[0345] In this embodiment, the target indicator refers to a perception-related indicator obtained by measuring the first signal.

[0346] Exemplarily, the measurement value of the target indicator is obtained by performing signal processing on the first signal on the target resource and / or other signals on other resources to obtain the measurement value of the target indicator. Exemplarily, the target resource is a time domain resource unit, a frequency domain resource unit, or a time-frequency domain resource unit that carries the first signal. The time domain resource unit may be one or more OFDM symbols, the frequency domain resource unit may be one or more subcarriers, and the time-frequency domain resource unit may be one or more REs. For example, one RE occupies 1 subcarrier in the frequency domain and 1 OFDM symbol in the time domain. Exemplarily, the other resources may be resources configured by high-level signaling. Exemplarily, the first signal may be a perception signal, such as a dedicated signal for perception services; or the first signal may be a communication signal, such as a reference signal, a synchronization signal, or other signals used for communication.

[0347] Exemplarily, the measured value of the target indicator may be a value determined based on the total received power. The total received power refers to the linear average of the total received power on the target resource, or the total received power refers to the product of the RSSI measured on the target resource or other resources and a preset coefficient.

[0348] In other words, 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 the signals of the serving cell and the non-serving cell, adjacent channel interference and thermal noise, etc.); or, the total received power = RSSI × K1, K1 is a preset coefficient, and the measurement resource of RSSI is the target resource or the other resource.

[0349] Exemplarily, the target indicators include at least one of the following three categories:

[0350] The first category of indicators includes indicators related to received power;

[0351] The second category of indicators includes indicators related to interference and noise power and / or received power;

[0352] The third category of indicators includes at least one of the following: an indicator determined based on the ratio of the first category of indicators to the second category of indicators, and an indicator determined based on the ratio of the first category of indicators to the total received power.

[0353] Exemplarily, the first category of indicators includes at least one of the following:

[0354] A first indicator (used to characterize the received power of the path associated with the perception target), wherein the first indicator refers to the linear average value (in W) of the received power of the path associated with the perception target in the channel response of the first signal on the target resource.

[0355] Exemplarily, the second category of indicators includes at least one of the following:

[0356] The second indicator refers to the sum (in W) of the linear average of the received power of paths other than the path associated with the sensing target in the channel response of the first signal on the target resource and the linear average of the interference and noise power of signals other than the first signal on the target resource or other resources, or the second indicator is equal to the difference between the total received power and the first indicator. For example, the second indicator = total received power - first indicator.

[0357] The third indicator refers to the linear average value (in W) of the interference and noise power of other signals other than the first signal on the target resource or other resources, or the third indicator is equal to the difference between the total received power and the received power of the first signal; for example, the third indicator = total received power - received power of the first signal; wherein the received power of the first signal is the RSRP of the first signal.

[0358] Fourth indicator: The fourth indicator is the linear average (in W) of the received power of paths other than the path associated with the sensing target in the channel response of the first signal on the target resource, or the fourth indicator is equal to the difference between the received power of the first signal and the first indicator. For example, the fourth indicator = the received power of the first signal - the first indicator; the received power of the first signal is the RSRP of the first signal.

[0359] Exemplarily, the third category of indicators may include perception-related signal to interference plus noise ratio (SINR), signal to noise ratio (SNR), signal to interference ratio (SIR), and reference signal receiving quality (RSRQ). For example, the third category of indicators may include at least one of the following:

[0360] The fifth indicator is equal to the ratio of the first indicator to the second indicator; that is, the fifth indicator = the first indicator / the second indicator.

[0361] The sixth indicator is equal to the ratio of the first indicator to the third indicator; that is, the sixth indicator = the first indicator / the third indicator.

[0362] The seventh indicator is equal to the ratio of the first indicator to the fourth indicator; that is, the seventh indicator = the first indicator / the fourth indicator.

[0363] The eighth indicator is equal to the ratio of the value obtained by multiplying the first indicator by the coefficient of the first indicator to the total received power; that is, the eighth indicator = K2×first indicator / total received power, where K2 is a preset coefficient.

[0364] The calculation method of each indicator is explained below.

[0365] Calculation method of the first indicator 1:

[0366] Taking the first device as an example, the first device performs channel estimation based on the transmitted first signal X(k) and the received signal Y(k) corresponding to the first signal to obtain a channel response (Channel Response) H(k) = Y(k) / X(k), where k = 0, 1, 2, ..., K-1 represents the resource unit index. After the first device obtains the channel response H(k), it transforms it to the first dimension and determines the path associated with the perception target in the path corresponding to the first dimension. The power of the path associated with the perception target is then calculated as the first indicator. If there are multiple paths associated with the perception target, the sum of the powers of the multiple paths is calculated as the first indicator.

[0367] The first dimension may include one of the following:

[0368] Delay dimension;

[0369] Doplevi;

[0370] Azimuth dimension;

[0371] Pitch angle dimension;

[0372] A dimension that is a combination of at least two of the delay dimension, the Doppler dimension, the azimuth dimension, and the elevation dimension, for example, the delay-Doppler dimension, the delay-Doppler-angle dimension, etc.

[0373] For example, H(f) is the channel response, where f = 0, 1, 2, ..., N-1 represents the frequency domain sampling point (e.g., subcarrier index), and H(f) can be transformed into the delay dimension (first dimension) by performing an inverse Fourier transform on it. For another example, H(f, t) is the channel response, where f = 0, 1, 2, ..., N-1 represents the frequency domain sampling point (e.g., subcarrier index), and t = 0, 1, 2, ..., M-1 represents the time domain sampling point (e.g., OFDM symbol index), and H(f, t) can be transformed into the time domain dimension by performing an inverse Fourier transform along the frequency domain dimension and a Fourier transform along the time domain dimension. Delay-Doppler dimension (first dimension); for another example, H(f,t,s) is the channel response, where f=0,1,2,…,N-1 represents the frequency domain sampling point (e.g., subcarrier index), t=0,1,2,…,M-1 represents the time domain sampling point (e.g., OFDM symbol index), and s=0,1,2,…,P-1 represents the spatial domain sampling point (antenna index or port index). Then, H(f,t,s) can be transformed into the delay-Doppler-angle dimension (first dimension) by performing an inverse Fourier transform along the frequency domain dimension, a Fourier transform along the time domain dimension, and a Fourier transform along the antenna domain dimension.

[0374] The method for the first device to determine a path associated with the perception target (referred to as the perception path for short) in the path corresponding to the first dimension includes:

[0375] The first device determines, among the paths corresponding to the first dimension, a path that satisfies a first condition as the path associated with the perception target;

[0376] The first condition includes at least one of the following:

[0377] The first parameter of the path exceeds a first threshold value or is within a first specific interval;

[0378] The difference between the first parameter of the first path and the first path or the reference path exceeds a second threshold value or is within a second specific interval;

[0379] The second parameter of the path satisfies the preset modulation rule;

[0380] Wherein, the first parameter includes at least one of the following: amplitude, power, intensity, energy, Doppler, delay, angle;

[0381] The second parameter includes at least one of the following: amplitude, power, intensity, energy, and phase.

[0382] Exemplarily, different first parameters correspond to different values ​​of the first threshold value or the value of the first specific interval range.

[0383] For example, the first condition includes at least one of the following:

[0384] The Doppler of the path exceeds the preset threshold corresponding to the Doppler or is within the specific range corresponding to the Doppler;

[0385] The delay of the path exceeds the preset threshold corresponding to the delay or is within the specific interval range corresponding to the delay;

[0386] The angle of the path exceeds the preset threshold corresponding to the angle or is within the specific interval range corresponding to the angle;

[0387] The Doppler difference between the path and the first arrival path (e.g., LOS path) or the reference path (e.g., the signal path reflected by a specific target (e.g., RIS / backscatterer / other known passive targets)) exceeds a preset threshold corresponding to the Doppler or is within a specific range corresponding to the Doppler;

[0388] The delay difference between the signal path and the first arrival path (e.g., LOS path) or the reference path (e.g., the signal path reflected by a specific target (e.g., RIS / backscatterer / other known passive target)) exceeds the preset threshold corresponding to the delay or is within the specific interval corresponding to the delay;

[0389] The angular difference between the signal path and the first arrival path (e.g., LOS path) or the reference path (e.g., the signal path reflected by a specific target (e.g., RIS / backscatterer / other known passive targets, etc.)) exceeds a preset threshold corresponding to the angle or is within a specific range corresponding to the angle.

[0390] In some embodiments, the first device determines, among the paths corresponding to the first dimension, a path that satisfies a first condition as the path associated with the perception target, which may be implemented as follows:

[0391] The first device determines a first path set among the paths corresponding to the first dimension, and a third parameter of each path in the first path set exceeds a third threshold value, and the third parameter includes at least one of the following: amplitude, power, intensity, and energy; the first device determines, in the first path set, a path that meets the first condition as the path associated with the perceived target.

[0392] Exemplarily, the path(s) in the first path set include those whose strength / power / energy exceeds a third threshold value among all path(s) after the channel response is transformed into the first dimension. For example, Figure 4 is a schematic diagram of multipath in the first dimension of the channel response provided by an embodiment of the present application; the horizontal axis represents the first dimension, and the vertical axis represents the normalized amplitude. As shown in Figure 4, paths 0, 1, 2, and 3 are path(s) in the first path set. The first device then determines the path(s) in the first path set that meet the first condition as the perceived path(s).

[0393] It should be noted that the result of determining the path associated with the perception target according to the above method may be that there is no path associated with the perception target. In this case, it can be understood that the perception target is not detected or perceived. In this case, there is no measurement value of the target indicator. At this time, the first device can also determine the first configuration information or the first index. The specific method can be the same as the embodiment below, by increasing the number of time-frequency resources or other methods to determine the first configuration information or the first index.

[0394] Exemplarily, in the case where there is no path associated with the perception target, the first configuration information determined by the first device or the first configuration information associated with the first index has a number of time-frequency resources increased by a preset value compared to the second configuration information.

[0395] The preset threshold or specific set interval mentioned above is sent to the first device by another device and determined by the other device based on prior perception information or perception requirements. Alternatively, the preset threshold or specific interval is determined by the first device based on prior perception information or perception requirements.

[0396] The priori perception information or perception requirements include the following information:

[0397] Perception services or perception service types, such as detecting the presence of a target, positioning, speed detection, distance detection, angle detection, acceleration detection, material analysis, component analysis, shape detection, classification, radar cross section RCS (Radar Cross Section, RCS) detection, polarization scattering characteristic detection, fall detection, intrusion detection, population statistics, indoor positioning, gesture recognition, lip reading recognition, gait recognition, expression recognition, facial recognition, respiration monitoring, heart rate monitoring, pulse monitoring, humidity / brightness / temperature / atmospheric pressure monitoring, air quality monitoring, weather condition monitoring, environmental reconstruction, topography, building / vegetation distribution detection, pedestrian or vehicle flow detection, crowd density, vehicle density detection, etc.; the perception service type can be to classify multiple different perception services according to certain characteristics, for example, according to function, it can be divided into detection-type perception services (for example, including intrusion detection, fall detection), parameter estimation-type perception services (distance, angle, speed calculation), recognition-type perception services (motion recognition, identity recognition), etc., and can also be divided according to the range of perception (close-range perception, medium-range perception, long-range perception), according to the degree of perception fineness (coarse-grained perception, fine force perception, etc.), according to power consumption / energy consumption, according to resource occupancy, etc.

[0398] Perception target area: refers to the location area where the perception object may exist, or the location area where imaging or environmental reconstruction is required;

[0399] Perception object type: classifies the perception object according to its possible motion characteristics. Each perception object type contains information such as the motion speed, motion acceleration, and typical RCS of a typical perception object.

[0400] The number of perceived targets, for example, paths 0, 1, 2, and 3 shown in FIG4 are the paths in the first path set, where paths 2 and 3 are the perceived paths that meet the first condition (for example, their delays meet the preset threshold), and paths 0 and 1 are the paths associated with other scatterers.

[0401] It is worth noting that for frequency range 1, the reference point for the first indicator 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 indicator measured and reported by the receiving device cannot be lower than the indicator of any single receiving channel. For frequency range 2, the first indicator measured for a receiving channel needs to be measured on the combined signals of the multiple antenna elements corresponding to the receiving channel.

[0402] When calculating the received power of the path associated with the perception target, it can also be the power of the path associated with the perception target in the first dimension and The difference between is taken as the first indicator, where N1 represents the number of paths associated with the perceived target. is the average power of multiple paths outside the first path set in the first dimension.

[0403] Method 1 for calculating the received power of the first signal:

[0404] The received power of the first signal may be obtained by the receiving device, transforming the channel response (Channel Response) H(k) into a first dimension, determining a first path set in the first dimension, and then calculating the power sum of all paths in the first path set.

[0405] Method 2 for calculating the received power of the first signal:

[0406] The received power of the first signal can also be the sum of the powers of all paths in the first path set in the first dimension and , where N2 represents the number of paths in the first path set.

[0407] The total received power is calculated as follows:

[0408] Total received power

[0409] The calculation method of the second indicator is:

[0410] The channel response H(k) is processed by the first filter to obtain H filter1 (k), then according to H filter1 (k) and the first signal X(k) to obtain the received signal Y after the first filtering process filter1 (k), that is, Y filter1 (k)=H filter1 (k)X(k). Then the received signal Y(k) is subtracted from the received signal Y after the first filtering process. filter1 (k) Thus we get the interference and noise signal Y σ1 (k), that is, Y σ1 (k) = Y(k) - Y filter1 (k), and then calculate the second indicator according to the following formula:

[0411] The first filtering process is used to eliminate noise and interference in the first dimension and paths associated with non-perceptual targets. For example, the first filtering process sets the amplitudes of all paths except those associated with the perceptual targets in FIG4 to zero. The channel response H after the first filtering process is filter1 (k) does not include noise, interference, or paths associated with non-perceived targets, but only includes paths associated with perceived targets.

[0412] Calculation method 1 of the third indicator:

[0413] The channel response H(k) is processed by the second filter to obtain H filter2 (k), then according to H filter2 (k) and the first signal X(k) to obtain the second filtered received signal Y filter2 (k), that is, Y filter2 (k)=H folter2 (k)X(k). Then the received signal Y(k) is subtracted from the received signal Y after the second filtering process. filter2 (k) Thus we get the interference and noise signal Y σ2 (k), that is, Y σ2 (k) = Y(k) - Y filter2 (k), and then calculate the third indicator according to the following formula:

[0414] The second filtering process may be a noise interference suppression process in the first dimension (for example, setting the amplitudes of the paths other than the first path set in FIG4 to zero), or a minimum mean square error (MMSE) filter. The channel response H after the second filtering process is filter2 (k) does not contain noise and interference, and only contains the paths in the first path set.

[0415] Calculation method 2 for the third indicator:

[0416] According to the average power of multiple paths outside the first path set in the first dimension Calculate the third index P σ2 ,Right now Where N represents the number of sampling points in the first dimension.

[0417] It is worth noting that if the receiving device determines that there are multiple sensing targets, or the receiving device obtains the number of sensing targets based on prior sensing information or sensing requirements, there are several methods:

[0418] Method 1:

[0419] Calculate the target indicators of each perception target separately. For example, in Figure 4, the path associated with each perception target is determined separately, and then the target indicators corresponding to each perception target are calculated separately. At this time, when calculating the second indicator corresponding to a perception target (such as perception target A), there are two methods: the second indicator of perception target A = total received power - the first indicator of perception target A; or, the second indicator of perception target A = total received power - the first indicator of perception target A - the first indicator of perception target B; (assuming there are two perception targets: A and B); similarly, there are two ways to calculate the fourth indicator: the fourth indicator of perception target A = the RSRP of the first signal - the first indicator of perception target A; or, the fourth indicator of perception target A = the RSRP of the first signal - the first indicator of perception target A - the first indicator of perception target B; (assuming there are two perception targets: A and B)

[0420] Method 2:

[0421] Calculate a target metric for multiple perception targets. For example, in Figure 4, determine the paths associated with any perception target, and then use these paths as the paths associated with the perception target. This is equivalent to treating multiple perception targets as a virtual perception target and then calculating the target metric corresponding to the virtual perception target.

[0422] Example 2:

[0423] In this embodiment, the first device is a receiving device of the first signal, that is, the receiving device of the first signal determines the first configuration information, the first configuration information is used to configure the first signal, or the first configuration information is the configuration information expected by the first device to configure the first signal.

[0424] At a first moment, the first device receives the first signal and determines a measured value of a target indicator indicated by the second information. Based on the measured value of the target indicator, the first device combines information included in the third information (including the target value, the fourth threshold value, and the fifth threshold value) to determine whether to adjust the time-frequency resources of the first signal.

[0425] In a case where the first device determines that the time-frequency resources of the first signal need to be adjusted, the first device further determines first configuration information.

[0426] Example 2-1:

[0427] In a typical implementation, the UE sends a first signal and the base station receives the first signal to perform sensing.

[0428] At the first moment, the base station receives the first signal and determines the measured value of the target indicator. Based on the measured value of the target indicator, the base station determines whether it is necessary to adjust the time-frequency resources of the first signal: including whether the UE needs to increase the number of time-frequency resources (REs) and whether the UE can reduce the number of time-frequency resources (REs); when the base station determines that it is necessary to adjust the time-frequency resources of the first signal, the base station determines the first configuration information, and the first configuration information is used to configure the first signal. The process of the base station making the above judgment and determining the first configuration information includes the following options:

[0429] The base station compares the measured value of the target indicator with the target value to obtain a difference value between the measured value of the target indicator and the target value (including at least one of the difference in linear values, the ratio of linear values, and the difference in logarithmic values ​​(dB)); based on the difference value, the base station determines the first configuration information.

[0430] For example, the measured value of the target indicator is the received power of the path associated with the sensing target (see Example 1), and the target value is a value agreed upon in a protocol or configured by the sensing function network element. If the measured value (logarithmic value) of the target indicator is X dB less than the target value (logarithmic value), the number of time-frequency resources of the first signal is increased so that the target indicator at the second moment is increased by X dB, and the first configuration information can be determined based on this.

[0431] The base station compares the measured value of the target indicator with the fourth threshold value. If the measured value of the target indicator is greater than or equal to the fourth threshold value, there is no need to adjust the number of time-frequency resources of the first signal. If the measured value of the target indicator is less than the fourth threshold value, the base station determines the first configuration information based on the difference between the measured value of the target indicator and the fourth threshold value (including at least one of the difference in linear values, the ratio of linear values, and the difference in logarithmic values ​​(dB)).

[0432] For example, the measured value of the target indicator is the received power of the path associated with the sensing target (see Example 1), and the fourth threshold value is a value agreed upon in a protocol or configured by the sensing function network element. If the measured value (logarithmic value) of the target indicator is X dB less than the fourth threshold value (logarithmic value), the transmit power should be increased by X dB, and the first configuration information can be determined based on this.

[0433] The base station compares the measured value of the target indicator with the fifth threshold value. If the measured value of the target indicator is less than or equal to the fifth threshold value, there is no need to adjust the number of time-frequency resources of the first signal. If the measured value of the target indicator is greater than the fifth threshold value, the base station determines the first configuration information based on the difference between the measured value of the target indicator and the fourth threshold value (including at least one of the difference in linear values, the ratio of linear values, and the difference in logarithmic values ​​(dB)).

[0434] For example, the measured value of the target indicator is the received power of the path associated with the sensing target (see Example 1), and the fourth threshold value is a value agreed upon in a protocol or configured by the sensing function network element. If the measured value (logarithmic value) of the target indicator is greater than the fifth threshold value (logarithmic value) by X dB, the transmit power may be reduced by X dB, and the first configuration information may be determined based on this.

[0435] After the base station determines the first configuration information, it sends at least part of the information, activation instructions, and deactivation instructions in the first configuration information to the UE; the specific solution can be found in the above description of the first operation, and will not be repeated here to avoid repetition.

[0436] Example 2-2:

[0437] In another typical implementation, the base station sends a first signal and the UE receives the first signal to perform sensing.

[0438] At the first moment, the UE receives the first signal and determines the measured value of the target indicator. Based on the measured value of the target indicator, the UE determines whether it is necessary to adjust the time-frequency resources of the first signal: including: whether the number of time-frequency resources (RE) needs to be increased, whether the number of time-frequency resources (RE) can be reduced; when the UE determines that it is necessary to adjust the time-frequency resources of the first signal, the UE determines the first configuration information or the first index according to the configured first mapping table. The first configuration information is the configuration information expected by the UE for configuring the first signal, and the first index is used to determine the first configuration information. The process of the UE making the above judgment and determining the first configuration information or the first index includes the following options:

[0439] The UE compares the measured value of the target indicator with the target value to obtain a difference value between the measured value of the target indicator and the target value (including at least one of the difference in linear values, the ratio of linear values, and the difference in logarithmic values ​​(dB)); based on the difference value, the UE determines the first configuration information or the first index.

[0440] For example, the measured value of the target indicator is the received power of the path associated with the sensing target (see Example 1), and the target value is a value agreed upon in a protocol or configured by the sensing function network element. If the measured value (logarithmic value) of the target indicator is X dB less than the target value (logarithmic value), the number of time-frequency resources of the first signal is increased so that the target indicator at the second moment is increased by X dB, and the first configuration information or the first index can be determined based on this.

[0441] The UE compares the measured value of the target indicator with the fourth threshold value. If the measured value of the target indicator is greater than or equal to the fourth threshold value, there is no need to adjust the number of time-frequency resources of the first signal. If the measured value of the target indicator is less than the fourth threshold value, the UE determines the first configuration information or the first index based on the difference between the measured value of the target indicator and the fourth threshold value (including: at least one of the difference in linear values, the ratio of linear values, and the difference in logarithmic values ​​(dB)).

[0442] For example, the measured value of the target indicator is the received power of the path associated with the sensing target (see Example 1), and the fourth threshold value is a value agreed upon in a protocol or configured by the sensing function network element. If the measured value (logarithmic value) of the target indicator is less than the fourth threshold value (logarithmic value) by X dB, the number of time-frequency resources of the first signal is increased so that the target indicator at the second moment is increased by X dB, and the first configuration information or the first index can be determined based on this.

[0443] The UE compares the measured value of the target indicator with the fifth threshold value. If the measured value of the target indicator is less than or equal to the fifth threshold value, there is no need to adjust the number of time-frequency resources of the first signal. If the measured value of the target indicator is greater than the fifth threshold value, the UE determines the first configuration information or the first index based on the difference between the measured value of the target indicator and the fourth threshold value (including at least one of the difference in linear values, the ratio of linear values, and the difference in logarithmic values ​​(dB)).

[0444] For example, the measured value of the target indicator is the received power of the path associated with the sensing target (see Example 1), and the fourth threshold value is a value agreed upon in a protocol or configured by the sensing function network element. If the measured value (logarithmic value) of the target indicator is greater than the fifth threshold value (logarithmic value) by X dB, the number of time-frequency resources of the first signal may be reduced, so that the target indicator at the second moment is reduced by X dB, and the first configuration information or the first index may be determined based on this.

[0445] The following is an exemplary description of the method for the UE to determine the first index.

[0446] Method 1: The UE may determine the first index based on the first mapping relationship information shown in Table 2.

[0447] Table 2

[0448] As shown in Table 2, the first mapping relationship information includes a correspondence between at least one configuration information and at least one index, and the UE can determine the index corresponding to the first configuration information as the first index based on the first mapping relationship information. For example, when the first configuration information is configuration information 2, the UE can determine 2 as the value of the first index. Exemplarily, the configuration information in the first mapping relationship information may include the number of time-frequency resources that the UE expects to use to configure the first signal, for example, including but not limited to at least one of the following: the time domain density of the first signal, the frequency domain density of the first signal, and the bandwidth of the first signal. Of course, Table 2 is only exemplary, and in other alternative embodiments, the number of configuration information or indexes in the first mapping relationship information can be any value.

[0449] Method 2: The UE may determine the first index based on the second mapping relationship information shown in Table 3.

[0450] Table 3

[0451] As shown in Table 3, assuming that the target indicator includes indicator A and indicator B, the UE may determine, based on the second mapping relationship information, the index corresponding to the interval in which the measured value of indicator A is located and / or the threshold value that indicator B is greater than as the first index. For example, when the measured value of indicator A is within the interval: [X1, Y1], and / or the measured value of indicator B is greater than Z1, the UE may determine 1 as the value of the first index. Of course, Table 3 is merely exemplary, and in other alternative embodiments, the number of intervals or the number of indices in the first mapping relationship information may be any value.

[0452] After the UE determines the first index, it sends / suggests / requests the first index to the base station; then the base station determines the first configuration information based on the first index for configuring the first signal, and sends at least part of the information in the first configuration information, activation instructions, deactivation instructions, and first indication information to the UE; the specific solution can be found in the above description of the second operation. To avoid repetition, it will not be repeated here.

[0453] Alternatively, after the UE determines the first configuration information expected to be used to configure the first signal, it can directly send / suggest / request the expected first configuration information to the base station. For example, the first configuration information may include the number of time-frequency resources expected by the UE for configuring the first signal, for example, including but not limited to at least one of the following: the time domain density of the first signal, the frequency domain density of the first signal, and the bandwidth of the first signal.

[0454] Example 3:

[0455] In this embodiment, the first device is a sending end device of the first signal. For example, the sending end device of the first signal determines first configuration information, and the first configuration information is used to configure the first signal.

[0456] Specifically, the first configuration information determined by the first device may be at least one of the following:

[0457] The first device receives the measurement value of the target indicator indicated by the second information, and determines the first configuration information according to the measurement value of the target indicator.

[0458] In this case, one of the following options is further included:

[0459] The first device receives the measurement value of the target indicator from the perception function network element;

[0460] The first device receives the measured value of the target indicator from the receiving device of the first signal. Prior to this, the receiving device of the first signal needs to obtain the second information from the perception function network element. The second information includes at least one of the following:

[0461] Information indicating the indicator type of the target indicator;

[0462] Indications of the first dimension;

[0463] Indication of the first condition: used to indicate the path associated with the perception target determined according to the first condition;

[0464] an indication of at least one of the first parameter, the second parameter, and the third parameter;

[0465] an indication of at least one of a first threshold value, a second threshold value, and a third threshold value;

[0466] An indication of at least one of a first specific range and a second specific range.

[0467] The first device receives the first measurement quantity indicated by the second configuration information, and determines the measurement value of the target indicator according to the first measurement quantity, and further determines the transmit power adjustment information.

[0468] In this case, one of the following options is further included:

[0469] The first device receives the first measurement value from the perception function network element;

[0470] The first device receives the first measurement quantity from the receiving device of the first signal. Prior to this, the receiving device of the first signal needs to obtain the first information from the perception function network element. The first information includes information indicating the measurement quantity type of the first measurement quantity.

[0471] In a typical implementation, the base station sends a first signal and the UE receives the first signal to perform a sensing service.

[0472] At a first moment, the UE receives a first signal and determines a measurement value of a target indicator. Then, the UE reports the measurement value of the target indicator to a base station.

[0473] After obtaining the measured value of the target indicator, the base station determines whether it is necessary to adjust the time-frequency resources of the first signal, including whether it is necessary to increase the number of time-frequency resources of the first signal or whether it is possible to reduce the number of time-frequency resources of the first signal. If the base station determines that it is necessary to adjust the time-frequency resources of the first signal, the base station determines the first configuration information. The process of the base station making the above judgment and determining the first configuration information can refer to the situation in Example 2.

[0474] After the base station determines the first configuration information, it sends at least part of the information, activation instructions, and deactivation instructions in the first configuration information to the UE; the specific solution can be found in the above description of the first operation, and will not be repeated here to avoid repetition.

[0475] Example 4:

[0476] In this embodiment, the first device is a perception function network element. For example, the perception function network element determines first configuration information, and the first configuration information is used to configure the first signal.

[0477] Specifically, the first configuration information determined by the first device may be at least one of the following:

[0478] The first device receives a measurement value of a target indicator from a receiving device of the first signal, and determines the first configuration information according to the measurement value of the target indicator.

[0479] Prior to this, the receiving end device of the first signal needs to obtain the second information from the perception function network element. The second information includes at least one of the following:

[0480] Information indicating the indicator type of the target indicator;

[0481] Indications of the first dimension;

[0482] Indication of the first condition: used to indicate the path associated with the perception target determined according to the first condition;

[0483] an indication of at least one of the first parameter, the second parameter, and the third parameter;

[0484] an indication of at least one of a first threshold value, a second threshold value, and a third threshold value;

[0485] An indication of at least one of a first specific range and a second specific range.

[0486] The first device receives a first measurement quantity from a receiving end device of the first signal, and determines a measurement value of the target indicator according to the first measurement quantity, and further determines the first configuration information.

[0487] Before this, the receiving end device of the first signal needs to obtain the first information from the perception function network element. The first information includes information for indicating the measurement quantity type of the first measurement quantity.

[0488] In a typical implementation, UE 1 sends a first signal and UE 2 receives the first signal to perform a sensing service.

[0489] At a first moment, UE 2 receives a first signal and determines a measured value of a target indicator. UE 2 then reports the measured value of the target indicator to a base station. Here, the base station is a perception function network element.

[0490] After obtaining the measured value of the target indicator, the base station determines whether it is necessary to adjust the time-frequency resources of the first signal, including whether it is necessary to increase the number of time-frequency resources of the first signal or whether it is possible to reduce the number of time-frequency resources of the first signal. If the base station determines that it is necessary to adjust the time-frequency resources of the first signal, the base station determines the first configuration information. The process of the base station making the above determination and determining the first configuration information is described in Example 2.

[0491] After determining the first configuration information, the base station sends at least part of the first configuration information, activation instructions, and deactivation instructions to UE 1 and UE 2; the specific solution can be found in the above description of the first operation, and will not be repeated here to avoid repetition.
