The base station is not limited to specific technical terms.

[0047] To enable those skilled in the art to better understand the embodiments of this application, the following description is provided first.

[0048] Communication and sensing integration refers to the integrated design of communication and sensing functions within the same system through spectrum sharing and hardware sharing. While transmitting information, the system can sense information such as location, distance, and speed, and detect, track, and identify target devices or events. The communication system and the sensing system complement each other, thereby improving overall performance and bringing a better service experience.

[0049] Future mobile communication systems, such as B5G or 6G systems, will possess sensing capabilities in addition to communication capabilities. Sensing capabilities refer to the ability of one or more devices to sense the location, distance, and speed of target objects through the transmission and reception of wireless signals, or to detect, track, identify, and image target objects, events, or environments. With the deployment of small base stations using high-frequency, high-bandwidth technologies such as millimeter waves and terahertz waves in 6G networks, the resolution of sensing will be significantly improved compared to centimeter waves, enabling 6G networks to provide more refined sensing services.

[0050] The integration of communication and radar is a typical application of communication-sensing fusion. In the past, radar systems and communication systems were strictly separated due to different research objects and focuses, and in most scenarios, the two systems were studied separately. In fact, radar and communication systems are both typical methods of information transmission, acquisition, processing, and exchange, and they share many similarities in terms of working principles, system architecture, and frequency bands. The design of integrated communication and radar is highly feasible, mainly in the following aspects: First, both communication and sensing systems are based on electromagnetic wave theory, using the transmission and reception of electromagnetic waves to complete information acquisition and transmission; second, both communication and sensing systems have structures such as antennas, transmitters, receivers, and signal processors, resulting in significant overlap in hardware resources; with technological advancements, their operating frequency bands also increasingly overlap; furthermore, they share similarities in key technologies such as signal modulation and reception detection, and waveform design. The integration of communication and radar systems can bring many advantages, such as cost savings, size reduction, power consumption reduction, improved spectral efficiency, and reduced mutual interference, thereby improving the overall system performance.

[0051] Currently, there has been considerable research on the integrated design of radar and communication systems. Typical joint designs include spectrum coexistence, where the two systems operate independently, allowing information exchange to reduce mutual interference; receiver sharing, where the transmitting ends of the two systems send their own signal waveforms, and the waveforms of the two systems need to be orthogonal so as not to affect their respective reception and detection; transmitter sharing, where the transmitting end transmits a joint waveform of radar and communication; and transmitter-receiver sharing, where the transmitting and receiving ends of the two systems share resources, which also requires the use of joint waveforms or waveforms with orthogonal relationships.

[0052] Sensing can be conducted in two modes: single-site and multi-site. Single-site sensing transmits a sensing signal and receives and analyzes the echo signal to extract sensing parameters. For example, a base station acts as both the transmitter and receiver, while a terminal or other object acts as the sensing target. Alternatively, dual-site or multi-site sensing can be used. Single-site transmitting and receiving are not co-located; other receivers receive and analyze the signal to extract sensing parameters. For example, base station 1 acts as the transmitter, while a terminal or base station 2 acts as the receiver. Similarly, in single-site or multi-site sensing, the transmitter can also be a terminal.

[0053] Communication systems require the joint transmission of modulated symbols carrying information and pilot symbols used for channel estimation, focusing primarily on decoding performance. Their channel estimation algorithms only need to estimate a composite channel with finite unknown parameters, typically optimizing throughput and transmission reliability. Performance metrics typically include spectral efficiency, channel capacity, signal-to-noise ratio (SNR) / signal-to-interference-plus-noise ratio (SINR), bit error rate (BER), block error rate (BLER), and symbol error rate (SER). In contrast, sensing systems do not need to consider information carrying during signal transmission, usually using optimized or unmodulated transmitted signals. The focus is on the changes the sensed target brings to the transmitted signal, i.e., response characteristics. Optimization typically aims to improve parameter estimation accuracy, and performance metrics may include ambiguity function, Cramer-Rao lower bound, root mean square error, mutual information, rate-distortion function, radar estimation rate, Welch lower bound, and other metrics related to the sensing scenario and requirements.

[0054] The processing method for perceived information provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0055] like Figure 2 As shown in the embodiments of this application, a method for processing perceived information is also provided, including:

[0056] Step 201: The first device reports the first sensing measurement result and the first information to the second device;

[0059] First sensing resource indication information, which is used to indicate the resource information corresponding to the first sensing measurement result.

[0060] The aforementioned first sensing measurement result refers to the result obtained by the first device through sensing measurement.

[0061] Optionally, the first device is a base station or a terminal, and the second device is a core network device, base station, or terminal. For example, the first device is a terminal, and the second device is a base station. Another example is that the first device is a terminal and / or a base station, and the second device is a sensing network function or sensing network element of the core network.

[0062] The first perception indicator mentioned above is an indicator for measuring perception performance.

[0063] In this embodiment, the second device sends sensing information, the first device receives sensing signals, and can obtain at least one sensing measurement result based on the sensing signals. Based on the indication of a sensing measurement result, the first sensing measurement result is obtained, and the first sensing measurement result, along with at least one of the first sensing index and the first sensing resource indication information related to the first sensing measurement result, is reported to the second device. This allows the second device to adjust the resource configuration information for subsequent sensing signal transmissions based on at least one of the first sensing index and the first sensing resource indication information. For example, if the sensing index indicating frequency domain position 1 and frequency domain position 2 in the first sensing index meets the sensing requirements, then the frequency domain position of the subsequent sensing signals transmitted by the second device is configured as frequency domain position 1 and frequency domain position 2, thereby effectively improving sensing performance.

[0087] At least one sample point in the inverse Fourier transform of the frequency domain channel response of the received sensing signal that has the largest amplitude or whose amplitude exceeds a preset threshold.

[0088] At least one sample point in the Fourier transform result of the first time-domain data that has the largest amplitude or exceeds the preset threshold;

[0089] At least one sample point in the delayed Doppler domain result that has the largest amplitude or whose amplitude exceeds a preset threshold.

[0090] Optionally, the second sensing signal component includes:

[0091] The amplitude corresponding to the target sample point, the sum of squares of the amplitudes corresponding to the target sample point, the mean of the amplitudes corresponding to the target sample point, or the square mean of the amplitudes corresponding to the target sample point;

[0092] The target sample points include at least one of the following:

[0093] The first sample point is all the sample values ​​of the frequency domain channel response of the received sensed signal.

[0094] The second sample point is the sample point other than the sample point corresponding to the first sensing signal component among the first sample points;

[0095] The third sample point is all the sample points in the inverse Fourier transform result of the frequency domain channel response of the received sensing signal.

[0096] The fourth sample point is the sample point other than the sample point corresponding to the first sensing signal component among the third sample points;

[0097] The fifth sample point is all the sample points in the Fourier transform result of the first time-domain data;

[0098] The sixth sample point is the sample point other than the sample point corresponding to the first sensing signal component among the fifth sample points.

[0099] Optionally, the first time-domain data is the frequency-domain channel response (such as the frequency-domain channel response corresponding to a subcarrier SC, resource unit RE, or physical resource block PRB) of the sensing signal received at different sampling times within the time-domain observation range, or the amplitude or square of the frequency-domain channel response corresponding to the preset frequency resource, or the phase, I-channel data, or Q-channel data of the preset frequency resource, or data obtained based on the first calculation result of the I-channel data and the Q-channel data.

[0100] The aforementioned time-domain observation range is related to sensing requirements. The first device can determine the aforementioned time-domain observation range based on sensing requirements. Alternatively, it can determine the aforementioned time-domain observation range based on instructions from the second device.

[0101] Optionally, the first operation corresponding to the first calculation result is I*cos(theta)+Q*sin(theta), where I represents I-channel data, Q represents Q-channel data, and theta is a certain angle value.

[0102] Optionally, the frequency domain channel response of the sensed signal includes the frequency domain channel response corresponding to at least one transceiver antenna combination.

[0103] In specific embodiments of this application, for multi-antenna (MIMO) scenarios, the frequency domain channel response of the received sensing signal can be the frequency domain channel response corresponding to a certain transceiver antenna combination (e.g., antenna 1 transmits and antenna 1 receives or antenna 1 transmits and antenna 2 receives), or it can be the combination of the frequency domain channel responses corresponding to at least two transceiver antenna combinations, such as the quotient or conjugate multiplication of the frequency domain channel responses corresponding to two transceiver antenna combinations.

[0104] Optionally, before the first device reports the first sensing measurement result and the first information to the second device, it further includes:

[0105] Determine at least one perception measurement result based on at least one of the perception indicators and perception requirements;

[0106] The first perception measurement result is determined based on the at least one perception measurement result.

[0107] Optionally, determining the first sensing measurement result based on the at least one sensing measurement result includes:

[0108] The first sensing measurement result is obtained by merging at least two of the sensing measurement results.

[0109] In a specific embodiment of this application, the first sensing measurement result for reporting can be directly selected from all sensing measurement results. For example, the first sensing measurement is one or more sensing measurement results selected from all sensing measurement results according to the corresponding sensing index. The selected sensing measurement results can be sensing measurement results corresponding to resource locations in different time domains, frequency domains, spatial domains, angle domains, code domains, time delay domains, Doppler domains, and antenna domains. For example, among the sensing results corresponding to multiple frequency domain positions (or SC, RE, or PRB), if the ratio of the target sensing signal component (i.e., the aforementioned first sensing signal component) corresponding to frequency domain position 1 and frequency domain position 2 to other sensing signal components (i.e., the aforementioned second sensing signal component) is greater than the ratio of the target sensing signal component to other sensing signal components corresponding to other frequency domain positions, then the sensing measurement results corresponding to frequency domain position 1 and frequency domain position 2 are determined as the first sensing measurement results, and the ratio of the target sensing signal component to other sensing signal components corresponding to frequency domain position 1 and frequency domain position 2 is determined as the first sensing index. Alternatively, if the sensing index in the sensing requirements specifies a threshold for the ratio of the target sensing signal component to other sensing signal components, and among the sensing results corresponding to multiple frequency domain positions (or SC, RE, or PRB), the ratio of the target sensing signal component to other sensing signal components corresponding to frequency domain position 1 and frequency domain position 2 exceeds this threshold, then the sensing measurement results corresponding to frequency domain position 1 and frequency domain position 2 are determined as the first sensing measurement results, and the ratio of the target sensing signal component to other sensing signal components corresponding to frequency domain position 1 and frequency domain position 2 is determined as the first sensing index.

[0110] The aforementioned first sensing measurement result can also be obtained by selecting at least two sensing measurement results from all sensing measurement results and merging these at least two sensing measurement results. That is, multiple sensing measurement results selected from all sensing measurement results according to the corresponding sensing index (which may be sensing measurement results corresponding to resource locations in different time domains, frequency domains, spatial domains, angle domains, code domains, time delay domains, Doppler domains, and antenna domains) are directly summed and merged or weighted summed and merged to obtain the sensing measurement result. The weighting factor of the weighted merging is related to the first sensing index. Optionally, phase alignment or phase offset operations may be included before merging. For example, among the sensing measurement results corresponding to multiple frequency domain positions (or SC, RE, or PRB), if the ratio of the target sensing signal component corresponding to frequency domain position 1 and frequency domain position 2 to other sensing signal components is greater than the ratio of the target sensing signal component corresponding to other frequency domain positions to other sensing signal components, then the sum of the sensing measurement results corresponding to frequency domain position 1 and frequency domain position 2 is determined as the first sensing measurement result, or the first sensing measurement result is obtained by multiplying the sensing measurement result corresponding to frequency domain position 1 by weighting factor 1 and the sensing measurement result corresponding to frequency domain position 2 by weighting factor 2. Here, weighting factor 1 can be the ratio R1 of the target sensing signal component corresponding to frequency domain position 1 to other sensing signal components, and weighting factor 2 can be the ratio R2 of the target sensing signal component corresponding to frequency domain position 2 to other sensing signal components, or weighting factor 1 is R1 / (R1+R2), and weighting factor 2 is R2 / (R1+R2). R1+R2 or R1*R2 is used as the first sensing index, or (target sensing signal component corresponding to frequency domain position 1 + target sensing signal component corresponding to frequency domain position 2) / (other sensing signal components corresponding to frequency domain position 1 + other sensing signal components corresponding to frequency domain position 2) is used as the first sensing index.

[0166] Receive reporting instruction information; for example, report according to the trigger reporting information of the second device. The trigger reporting information may be included in the first sensing instruction information mentioned above, or the second device may send the trigger reporting information separately.

[0167] The calculated sensing measurement result is greater than a preset threshold. For example, the first device performs a threshold decision on the sensing measurement result obtained after processing the sensing signal, and reports it to the second device when the result exceeds a preset threshold (which may be specified by the second device).

[0168] Optionally, the first device reports the first sensing measurement result and the first information to the second device, including:

[0169] The first device receives first sensing indication information sent by the second device, the first sensing indication information being used to assist the first device in determining at least one of the first sensing measurement result and first information;

[0170] The first device reports the first sensing measurement result and the first information to the second device based on the first sensing indication information.

[0171] Optionally, the first sensing indication information includes at least one of the following:

[0172] Perception requirements include perception indicators and the conditions that the corresponding perception indicators need to meet, such as the minimum threshold of the ratio of the target perception signal component to other perception signal components, or the range of variation of the variance of the perception measurement results.

[0173] The sensing measurement quantity (corresponding to the sensing measurement result) is used to instruct the first device to calculate the corresponding sensing measurement result based on the received sensing signal;

[0174] The first observation range when calculating sensory measurement results or sensory indicators;

[0175] The resource location information corresponding to the first sensing measurement result is indicated. The resource location information includes at least one of the resource locations in the time domain, frequency domain, spatial domain, angle domain, code domain, time delay domain, Doppler domain, and antenna domain. For example, frequency domain location 1 (or SC1 or RE1 or PRB1). In this case, after calculating the sensing measurement quantity, the first device directly uses the sensing measurement result corresponding to frequency domain location 1 as the first sensing measurement result. Or, transmitting antenna 1 and receiving antenna 1. In this case, the first device directly uses the sensing measurement result corresponding to antenna transmitting and receiving combination 1 (transmitting antenna 1 and receiving antenna 1) as the first sensing measurement result.

[0176] The merging method for sensing measurement results includes at least the following: direct summation, weighted summation, quotient (point division, i.e., element-wise division, for example, if the sensing measurement results are two sets of vectors, point division means dividing corresponding elements in the two sets of vectors), conjugate multiplication, and difference. For example, if the indicated merging method is direct summation, and the first device calculates the sensing measurement results corresponding to multiple frequency domain positions, then the first device adds the sensing measurement results of multiple frequency domain positions as the first sensing measurement result. Another example is that if the indicated merging method is quotient (point division), and the second device calculates the frequency domain channel response corresponding to antenna combination 1 (transmitting antenna 1 and receiving antenna 1) and antenna combination 2 (transmitting antenna 1 and receiving antenna 2), then the first device takes the quotient of the frequency domain channel response corresponding to the two antenna combinations as the first sensing measurement result.

[0177] Optionally, the first observation range includes at least one of the following:

[0178] Time-domain observation range;

[0179] Frequency domain observation range;

[0180] The observation range in the airspace or angular domain;

[0181] Code domain observation range;

[0182] Time-delay domain observation range;

[0183] Doppler domain observation range;

[0184] Antenna domain observation range.

[0185] The aforementioned first sensing range can be an index range determined according to pre-agreed rules, such as the n1th frame to the n2th frame, or the sample points n1 to n2 after a fixed number of FFT / IFFT. It can also be a range represented by actual physical units, such as f1 to f2 Hz, t1 to t2 s, {transmitting antenna tx1, transmitting antenna tx2, receiving antenna rx1, receiving antenna tx2}, etc.

[0186] The method for processing sensing information in this application embodiment involves a first device reporting a first sensing measurement result and first information to a second device. The first information includes at least one of a first sensing index and a first sensing resource indication information. Based on at least one of the first sensing index and the first sensing resource indication information, the second device adjusts the resource configuration information for subsequent sensing signals, which can effectively improve sensing performance.

[0187] like Figure 3 As shown in the embodiments of this application, a method for processing perceived information is also provided, including:

[0188] Step 301: The second device receives the first sensing measurement result and the first information reported by the first device;

[0189] Step 302: The second device adjusts the configuration information of the sensing signal according to the first sensing measurement result and the first information, wherein the configuration information includes the resource information of the sensing signal;

[0190] The first information includes at least one of the following:

[0191] The first perception index is a perception index associated with the first perception measurement result.

[0192] First sensing resource indication information, which is used to indicate the resource information corresponding to the first sensing measurement result.

[0193] The first information and the first sensing measurement result have been described in detail in the method embodiment on the first device side, and will not be repeated here.

[0194] For example, if the perception indicator of the first target perception resource meets the perception requirements, then the first target perception resource is adjusted to the resource information of the perception signal, that is, the perception signal is subsequently sent on the first target perception resource.

[0195] For example, if the first sensing resource indication information is the second target sensing resource (such as PRB1) multiple times in a row, or if the second target sensing resource appears the most times in multiple first sensing resource indication information, then the configuration for sending sensing signals is adjusted to send sensing signals on the second target sensing resource.

[0196] Optionally, the first perceived resource indication information is used to indicate at least one of the following:

[0197] Temporal resource information corresponding to the first sensing measurement result;

[0198] Frequency domain resource information corresponding to the first sensing measurement result;

[0199] The spatial or angular resource information corresponding to the first sensing measurement result;

[0200] The code domain resource information corresponding to the first sensing measurement result;

[0201] The time-delay domain resource information corresponding to the first sensing measurement result;

[0202] Doppler domain resource information corresponding to the first sensing measurement result;

[0203] Antenna domain resource information corresponding to the first sensing measurement result.

[0204] Optionally, before the second device receives the first sensing measurement result and first information reported by the first device, it further includes:

[0205] The second device sends first sensing indication information, which is used to assist the first device in determining at least one of the first sensing measurement result and the first information.

[0206] Optionally, the first sensing indication information includes at least one of the following:

[0207] Perceive needs;

[0208] Sensing and measuring quantity;

[0209] The first observation range when calculating sensory measurement results or sensory indicators;

[0210] Indicates the resource location information corresponding to the first sensing measurement result;

[0211] Methods for merging sensory measurement results.

[0212] Optionally, the first observation range includes at least one of the following:

[0213] Time-domain observation range;

[0214] Frequency domain observation range;

[0215] The observation range in the airspace or angular domain;

[0216] Code domain observation range;

[0217] Time-delay domain observation range;

[0218] Doppler domain observation range;

[0219] Antenna domain observation range.

[0220] The aforementioned first sensing indication information has been described in detail in the method embodiment on the first device side, and will not be repeated here.

[0221] The above configuration information includes at least one of the following:

[0222] The location of resources in the time domain, frequency domain, spatial domain, angle domain, code domain, time delay domain, Doppler domain, and antenna domain of the sensed signal.

[0223] For example, if the sensing indicators at frequency domain positions 1 and 2 in the first sensing indicators reported by the first device meet the sensing requirements, then the frequency domain configuration for the next sensing signal transmission will be to transmit the sensing signal at frequency domain positions 1 and 2. As another example, if the sensing indicators of antenna combination 1 (transmitting antenna 1 and receiving antenna 1) and antenna combination 2 (transmitting antenna 1 and receiving antenna 2) in the first sensing indicators reported by the first device meet the sensing requirements, then the antenna domain configuration for the next sensing signal transmission will be to transmit the sensing signal at transmitting antenna 1.

[0224] In the apparatus of this application embodiment, the second device can adjust the resource configuration information for subsequent transmission of sensing signals based on the first sensing index and / or the first sensing resource indication information reported by the first device, thereby effectively improving sensing performance.

[0225] It should be noted that, in the embodiments of this application, the transmission and reception of sensing signals during the sensing signal measurement process can be carried out in the following ways:

[0226] Method 1: Base station A transmits sensing signals, and base station B receives sensing signals.

[0227] In this approach, base station A serves as the second device and base station B serves as the first device; or, the core network serves as the second device and base stations A / B serve as the first device.

[0228] Method 2: The base station sends a sensing signal, and the UE receives the sensing signal.

[0229] In this approach, the base station acts as the second device and the UE acts as the first device; or, the core network acts as the second device and the base station / UE acts as the first device.

[0230] Method 3: Base station transmits and receives data independently.

[0231] In this approach, the core network acts as the second device, and the base station acts as the first device.

[0232] Method 4: UE transmits and receives data independently.

[0233] In this approach, the base station acts as the second device and the UE acts as the first device, or the core network acts as the second device and the UE acts as the first device.

[0234] Method 5: UE transmits, base station receives.

[0235] In this approach, the core network acts as the second device, and the base station acts as the first device.

[0236] Method 6: UE A transmits, UE B receives.

[0237] In this configuration, UE A acts as the second device and UE B acts as the first device. Alternatively, the access base station of UE A / B acts as the second device and UE A / B acts as the first device; or, the core network acts as the second device and UE A / B acts as the first device. Alternatively, the core network acts as the second device and the access base station of UE A / B acts as the first device.

[0238] In this embodiment of the application, the sensing signal transmitting device can be multiple devices, and the sensing signal receiving device can be multiple devices; the base station mentioned above can also be a TRP, AP, Relay, RIS, etc.

[0239] The sensing services in this application embodiment include, but are not limited to, the following services:

[0240] Object feature detection: Information that can reflect the attributes or state of a target object, which can be at least one of the following: the position of the target object, the velocity of the target object, the acceleration of the target object, the material of the target object, the shape of the target object, the category of the target object, the radar cross section (RCS) of the target object, polarization scattering characteristics, etc.

[0241] Event detection: Information related to the target event, that is, information that can be detected / perceived when the target event occurs. Examples include: fall detection, intrusion detection, quantity statistics, indoor positioning, gesture recognition, lip reading, gait recognition, facial expression recognition, respiratory monitoring, heart rate monitoring, etc.

[0242] Environmental monitoring: humidity, brightness, temperature and humidity, atmospheric pressure, air quality, weather conditions, topography, building / vegetation distribution, population statistics, crowd density, vehicle density, etc.

[0243] The following section uses respiratory detection as an example to explain in detail the processing method of the perceived information in this application.

[0244] Example 1: The UE calculates perception indicators and selects to report perception measurement results.

[0245] The sensing requirement is respiratory detection. The sensing measurement is performed by the base station sending a sensing signal, the UE receiving the sensing signal and performing certain respiratory detection-related calculations to obtain the first sensing measurement result that needs to be reported to the base station.

[0246] (1) The base station transmits sensing signals according to sensing requirements and / or sensing signal configurations. The sensing requirements and / or sensing signal configurations may come from network functions or network elements of the core network (such as sensing network functions / sensing network elements).

[0247] (2) The base station sends a first perception indication information to the UE to assist the UE in determining the first perception measurement result and / or the first perception index that needs to be reported. The first perception indication information may be determined by the base station according to the perception requirements and / or perception signal configuration, or it may come from the network function or network element of the core network (such as perception network function / perception network element).

[0248] Specifically, the first sensing indication information contains indication information related to the processing of respiratory detection signals; see the description in the subsequent processing flow for details.

[0249] (3) The UE receives the sensing signal sent from the base station and obtains the frequency domain channel response H through channel estimation, such as least squares (LS) channel estimation (i.e. H = Y. / X, where Y is the frequency domain form of the received sensing signal and X is the frequency domain form of the local sensing signal) or minimum mean square error (MMSE) channel estimation. Y. / X means dividing the corresponding elements of Y and X.

[0250] (4) The UE performs further processing on H based on the received first sensing indication information, including:

[0251] Based on the antenna domain combining method indicated in the first sensing instruction information, the H values ​​corresponding to the first antenna combination and the second antenna combination are quotiented to obtain H_ratio. Assuming there are multiple antenna combinations, multiple H_ratios are obtained. For example, with 1 transmit and 4 receive antennas, there are 4 antenna combinations, resulting in 6 H_ratios, as shown below:

[0252] H_ratio1=H_tx1_rx1. / H_tx1_rx2;

[0253] H_ratio2=H_tx1_rx1. / H_tx1_rx3;

[0254] H_ratio3=H_tx1_rx1. / H_tx1_rx4;

[0255] H_ratio4=H_tx1_rx2. / H_tx1_rx3;

[0256] H_ratio5=H_tx1_rx2. / H_tx1_rx4;

[0257] H_ratio6=H_tx1_rx3. / H_tx1_rx4;

[0258] Wherein, H_tx1_rx1 represents the frequency domain channel response H corresponding to transmit antenna 1 and receive antenna 1 of the transmit antenna combination, and so on.

[0259] If there are multiple SCs or PRBs, then calculate H_ratio for each SC or PRB.

[0260] The time-domain format of the sensing signal sent by the base station to the UE corresponds to the time-domain sampling period / sampling frequency of the breathing detection sensing data on the UE side. For example, if the sensing signal is sent once every 20ms, then the time-domain sampling period of the breathing detection sensing data on the UE side is 20ms and the sampling frequency is 50Hz. The time-domain format of the sensing signal sent by the base station is determined by the base station according to the sensing requirements, or by the network function or network element of the core network (such as sensing network function / sensing network element) according to the sensing requirements. In principle, it needs to meet the sensing time-domain Nyquist sampling criterion, that is, the time-domain sampling frequency needs to be greater than or equal to twice the maximum breathing frequency.

[0261] (5) The base station notifies the UE of the time-domain observation window T1 (i.e., the time-domain observation range mentioned above) through the first sensing indication information; for each respiratory detection data time-domain sampling point in window T1, there are multiple SC or PRB and multiple antenna combinations with H_ratio. Take the H_ratio corresponding to a certain SC or PRB and a certain antenna combination. Within window T1, multiple H_ratios reflecting the respiratory pattern can be obtained. The first time-domain data can be further calculated. The calculation method can be:

[0262] The frequency domain channel response quotient H_ratio within window T1 is used as the first time domain data;

[0263] The amplitude of the frequency domain channel response quotient H_ratio within window T1 is used as the first time domain data;

[0264] The phase of the frequency domain channel response quotient H_ratio within window T1 is used as the first time domain data;

[0265] The I-channel data of the frequency domain channel response quotient H_ratio within window T1 is used as the first time domain data;

[0266] The Q-channel data of the frequency domain channel response quotient H_ratio within window T1 are used as the first time domain data;

[0267] The projection operation (the projection operation can be I*cos(theta)+Q*sin(theta), where theta is a certain angle value, different theta correspond to different projections, I represents I data and Q represents Q data) of the frequency domain channel response quotient H_ratio within window T1 is used as the first time domain data.

[0268] Optionally, candidate first time-domain data is obtained by processing H_ratio using the method described above, and the candidate first time-domain data is preprocessed to obtain the first time-domain data. The preprocessing may be:

[0269] Low-pass or band-pass filtering, such as using a Butterworth filter;

[0270] Outlier removal can be achieved through methods such as Hampel filtering or setting an outlier threshold. For example, take all or part of the sample points in the time-domain observation window T1, calculate the mean and standard deviation, and set the outlier threshold to mean ± t * standard deviation, where t is a real number factor. Sample points that exceed the threshold are replaced by the previous or next sample point.

[0271] Smoothing filtering, such as Savitzky-Golay filtering.

[0272] (6) After obtaining the first time-domain data, the respiratory detection sensing index is determined according to the first sensing indication information sent by the base station. Then, the first time-domain data for calculating the first sensing measurement result is selected from the first time-domain data corresponding to different SC or PRB and / or different antenna combinations and / or different projections. The method for determining the respiratory detection sensing index can be:

[0273] Method 1: Perform FFT transformation on the first time domain data, calculate the ratio of the target sensing signal component to other sensing signal components, and define it as BNR (Breath to Noise Ratio). The target sensing component is the amplitude or square of the sample point with the largest amplitude in the FFT result of the first time domain data. It can be considered that the sample point with the largest amplitude is the sample point corresponding to the respiratory rate.

[0274] Optionally, based on the frequency domain observation window F1 in the first sensing indication information sent by the base station, the sample point with the largest amplitude within the window F1 is searched as the sample point corresponding to the breathing frequency. F1 is determined by the base station based on the breathing rate range in the breathing detection sensing service, or by the network functions or network elements of the core network (such as sensing network functions / sensing network elements) based on sensing requirements. For example, F1 refers to the frequency range of f1~f2 Hz and -f2~-f1 Hz, i.e., the actual frequency range. Figure 4As shown in the diagram, the two parallel rectangles represent the frequency domain observation window F1. Within F1, the sample points with the largest amplitudes are found to correspond to frequencies of 0.5Hz and -0.5Hz. The sum of amplitudes or the sum of squares of amplitudes corresponding to the two sample points of 0.5Hz and -0.5Hz are taken as the target sensing component. The sum of amplitudes or the sum of squares of amplitudes corresponding to all sample points, or the mean or mean square of amplitudes corresponding to all sample points, or the sum of amplitudes or the sum of squares of amplitudes corresponding to all or some sample points other than 0.5Hz and -0.5Hz, or the mean or mean square of amplitudes corresponding to all or some sample points other than 0.5Hz and -0.5Hz, are taken as other sensing signal components. Then, BNR = target sensing component / other sensing components is calculated.

[0275] Alternatively, assuming the time-domain observation window T1 includes N sample points, i.e., the number of FFT points is N, the time-domain sampling frequency Fs = 1 / Ts can be obtained from the time-domain sampling period Ts and the number of FFT points. The frequency domain interval between adjacent sample points after FFT is deltaf = Fs / N. The above actual frequency range is converted into sample indices of the FFT result using the following conversion methods: idx1 = f(f1 / deltaf), idx2 = f(f2 / deltaf), idx3 = f((Fs-f2) / deltaf), idx4 = f((Fs-f1) / deltaf), where f() represents rounding up, rounding down, or rounding to the nearest integer. Therefore, F1 refers to the sample point indices idx1~idx2 and idx3~idx4 after FFT. Figure 5 As shown in the diagram. The two rectangles on the left and right represent the frequency domain observation window F1. Within F1, the sample points with the largest amplitudes are found, corresponding to FFT result indices 6 and 996 (at this time, N = 1000, Fs = 100Hz, and indices 6 and 996 correspond to 0.5Hz and -0.5Hz respectively). The amplitudes and / or the sum of squares of the amplitudes corresponding to the two sample points at indices 6 and 996 are then taken as the target sensing component. The calculation methods for other sensing signal components and BNR are the same as above.

[0276] Method 2: Calculate the variance or standard deviation of the first time domain data and use the variance or standard deviation as a respiratory detection perception indicator.

[0277] (7) After obtaining the respiratory detection sensing index (i.e. the above BNR or variance / standard deviation), select the first time domain data corresponding to the SC or PRB with the largest BNR or the largest variance / standard deviation and / or antenna combination and / or IQ projection (if any) to calculate the first sensing measurement result to be reported, which is called the second time domain data.

[0278] Alternatively, based on the first sensing indication information sent by the base station, a sensing index threshold is determined, and then the first time domain data with BNR or variance / standard deviation exceeding the threshold is selected from the first time domain data corresponding to different SC or PRB and / or different antenna combinations and / or different projections. This data is used to calculate the first sensing measurement result to be reported, and is called the second time domain data.

[0279] The method for calculating and reporting the first sensing measurement result based on the aforementioned second time-domain data can be as follows:

[0280] Method 1: All or part of the second time domain data is directly used as the first sensing measurement result. The part of the second time domain data can be the second time domain data corresponding to a certain segment of the sub-time domain observation window in the time domain observation window T1, or the second time domain data in the time domain observation window T1 can be extracted to obtain part of the second time domain data. The extraction rule can be carried in the base station sensing indication message or implemented by the UE. However, the sampling frequency corresponding to the extracted part of the second time domain data needs to be greater than or equal to twice the maximum breathing frequency.

[0281] Method 2: All or part of the results of the FFT operation on the second time-domain data are used as the first sensing measurement result. The part of the FFT operation result can be the result located within the frequency domain observation window F1 from all the results of the FFT operation on the second time-domain data.

[0282] Method 3: All or part of the results of the autocorrelation operation of the second time domain data are used as the first sensing measurement result. The part of the autocorrelation operation refers to the first X results of the total autocorrelation operation, where X is at least greater than or equal to the sampling frequency of the second time domain data divided by the minimum possible respiratory rate.

[0283] Method 4: Peak information of the second time-domain data, such as Figure 6 As shown, the second time-domain data is the amplitude of the frequency domain channel response quotient H_ratio within the window T1 corresponding to the SC or PRB with the largest BNR or the largest variance / standard deviation and / or antenna combination and / or IQ projection (if any). The sample points with time-domain indices of 1, 200, 400, 600, 800, and 1000 are the peak points. The time-domain index and / or time-domain amplitude of the peak points are reported as the first sensing measurement result.

[0284] Specifically, if there are multiple second time-domain data sets, the second time-domain data can be merged first and then the first sensing measurement result can be calculated as described above. Alternatively, multiple first sensing measurement results can be calculated as described above, and then merged to obtain the first sensing measurement result for reporting. The merging method can be direct addition or weighted addition. For example, if there are two sets of second time-domain data sets, namely second time-domain data 1 corresponding to antenna combination 1, IQ projection 1, SC1 and second time-domain data 2 corresponding to antenna combination 1, IQ projection 1, SC2, with sensing indices BNR1 and BNR2 respectively, the result can be second time-domain data 1 + second time-domain data 2. After performing FFT on time-domain data 2, all or part of the results are used as the first sensing measurement result; or after performing FFT on second time-domain data 1*BNR1+second time-domain data 2*BNR2, all or part of the results are used as the first sensing measurement result; or all or part of the results of FFT on second time-domain data 1 are used to obtain the first sensing measurement result 1, and all or part of the results of FFT on second time-domain data 2 are used to obtain the first sensing measurement result 2, and the first sensing measurement result 1*BNR1+first sensing measurement result 2*BNR2 are used as the reported first sensing measurement result.

[0285] (8) Use the SC or PRB and / or antenna combination corresponding to the first sensing measurement result as the first sensing resource indication information.

[0286] (9) After receiving the first perception measurement result and / or the first perception index and / or the first perception resource indication information reported by the UE, the base station adjusts the relevant configuration of the perception signal transmission. For example, if the first perception resource indication information is PRB1 and PRB2, antenna combination 1 (transmitting antenna 1 and receiving antenna 1) and antenna combination 2 (transmitting antenna 1 and receiving antenna 2), the base station adjusts the perception signal transmission configuration to transmit the perception signal on PRB1 and PRB2 and antenna 1.

[0287] The base station can adjust the configuration for transmitting sensing signals in real time, i.e., after receiving the first sensing measurement result and / or the first sensing index and / or the first sensing resource indication information reported by the UE, the relevant configuration can be adjusted before the next transmission of sensing signals. Alternatively, it can be adjusted cumulatively, for example, after receiving the first sensing measurement result and / or the first sensing index and / or the first sensing resource indication information reported by the UE multiple times, the relevant configuration for transmitting sensing signals can be adjusted after statistics are performed. For example, if the first sensing resource indication information is PRB1 multiple times consecutively, or if PRB1 appears the most times in multiple first sensing resource indication information, then the configuration for transmitting sensing signals can be adjusted to transmit sensing signals on PRB1.

[0288] Example 2: The base station calculates the perception index and instructs the UE to report the perception measurement results.

[0289] The sensing requirement is respiratory detection. The sensing measurement execution method is that the base station sends a sensing signal, and the UE receives the sensing signal but does not perform respiratory detection-related calculations. At this time, the first sensing measurement result reported by the UE is the primary measurement result, such as the initial channel frequency domain response H. The base station determines the first sensing index and the first sensing resource based on the respiratory detection sensing requirement and / or the primary measurement quantity reported by the UE, and instructs the UE to report the first sensing measurement result.

[0290] (1) The base station transmits sensing signals according to sensing requirements and / or sensing signal configurations. The sensing requirements and / or sensing signal configurations may come from network functions or network elements of the core network (such as sensing network functions / sensing network elements).

[0291] (2) The UE receives the sensing signal sent from the base station and obtains the frequency domain channel response H through channel estimation, such as least squares (LS) channel estimation (i.e., H = Y. / X, where Y is the frequency domain form of the received sensing signal and X is the frequency domain form of the local sensing signal) or minimum mean square error (MMSE) channel estimation.

[0292] (3) The UE reports the above H as the initial first perception measurement result to the base station.

[0293] (4) The base station receives the first perception measurement result H reported by the UE, and further processes H to obtain the first perception index and / or the first perception resource indication. The processing of H and the calculation of the first perception index and / or the first perception resource indication are the same as in Example 1.

[0294] (5) The base station sends first perception indication information to the UE according to the first perception indicator and / or the first perception resource indication, which is used to instruct the UE to determine the first perception measurement result that needs to be reported or updated. For example, if the first perception resource indication information is PRB1 and PRB2, antenna combination 1 (transmitting antenna 1 and receiving antenna 1) and antenna combination 2 (transmitting antenna 1 and receiving antenna 2), the base station instructs the UE to use the frequency domain channel response H2 corresponding to PRB1 and PRB2 and transmitting antenna 1 as the first perception measurement result and report it to the base station. That is, the UE adjusts the reported first perception measurement result according to the perception indication information.

[0295] (6) The UE periodically reports the initial first perception measurement result H to the base station. The base station further processes H and updates the first perception index and / or the first perception resource indicator. Then, it instructs the UE to make a new reporting rule through the perception indicator information, that is, to adjust the reported first perception measurement result.

[0296] Alternatively, the base station calculates the first perception index based on the first perception measurement result H2 reported by the UE, compares the first perception index with the perception index threshold, and if the threshold requirement is not met, the base station instructs the UE to report the initial first perception measurement result H through the perception indication information. The base station further processes H and updates the first perception index and / or the first perception resource indication, and then instructs the UE to report a new rule through the perception indication information, that is, adjust the reported first perception measurement result.

[0297] (7) The base station adjusts the relevant configuration of the transmitted sensing signal according to the calculated first sensing index and / or first sensing resource indication information. The specific adjustment method is the same as in Example 1.

[0298] Example 3: The core network calculates perception indicators and instructs base stations and / or UEs to report perception measurement results.

[0299] The sensing requirement is respiratory detection. The sensing measurement is performed by the base station sending a sensing signal and the UE receiving the sensing signal, or by the base station sending and receiving on its own, or by the base station sending and receiving between base stations, or by the UE sending and receiving to the base station, or by the UE sending and receiving on its own, or by the UE sending and receiving between UEs.

[0300] (10) The base station and / or UE execute the breathing detection measurement process, perform certain breathing detection perception related calculations, and obtain the first perception measurement result that needs to be reported to the core network.

[0301] (20) The base station and / or UE do not perform breathing detection related calculations.
