[0052] In some embodiments, network-side devices and terminals may have perception capabilities in addition to communication capabilities. Perception capabilities refer to one or more devices with the ability to sense the position, distance, speed, and other information of a target object through the transmission and reception of wireless signals, or to detect, track, identify, and image a target object, event, or environment. Some perception functions and application scenarios are shown in Table 1:

[0053] Table 1

[0054] It should be noted that the perception categories shown in Table 1 above are only examples, and the embodiments of the present application do not limit the categories of perception measurements.

[0055] In addition, the embodiments of the present application can be applied to the communication and perception integration scenario, where communication and perception integration refers to the integrated design of communication and perception functions through spectrum sharing and hardware sharing in the same system. While transmitting information, the system can perceive information such as direction, distance, speed, and detect, track, and identify target devices or events. The communication system and the perception system complement each other to achieve overall performance improvement and bring a better service experience.

[0056] For example: the integration of communication and radar is a typical communication-perception integration (communication-perception fusion) application, and the integration of communication and radar systems can bring many advantages, such as cost savings, size reduction, power consumption reduction, spectrum efficiency improvement, and mutual interference reduction, thereby improving the overall performance of the system.

[0057] In the embodiment of the present application, depending on the difference between the sending node and the receiving node of the perception signal, the six types of perception links shown in Figure 2 may be included but not limited to. It should be noted that each perception link in Figure 2 is illustrated by taking a sending node and a receiving node as an example. In the actual system, different perception links can be selected according to different perception needs. Each perception link may have one or more sending nodes and one receiving node, and the actual perception system may include a variety of different perception links. In addition, the perception targets in Figure 2 take people and cars as examples, and assuming that people and cars do not carry or install signal receiving / transmitting equipment, the perception targets of the actual scene will be richer.

[0058] Sensing link 1: The base station transmits and receives sensing signals autonomously. In this mode, the base station sends a sensing signal and obtains the sensing result by receiving the echo of the sensing signal.

[0059] Sensing link 2: inter-base station air interface sensing. In this mode, base station 2 receives the sensing signal sent by base station 1 and obtains the sensing result.

[0060] Perception link 3: Uplink air interface perception: In this mode, the base station receives the perception signal sent by the terminal and obtains the perception result.

[0061] Perception link 4: Downlink air interface perception: In this mode, the terminal receives the perception signal sent by the base station and obtains the perception result.

[0062] Perception link 5: Terminal self-transmitting and self-receiving perception. In this mode, the terminal sends a perception signal and obtains the perception result by receiving the echo of the perception signal.

[0063] Perception link 6: Sidelink perception between terminals. For example, terminal 2 receives a perception signal sent by terminal 1 and obtains a perception result, or terminal 1 receives a perception signal sent by terminal 2 and obtains a perception result.

[0064] In some embodiments, the signaling transmission between the wireless access network device and the terminal, or between different terminals, may be through Radio Resource Control (RRC) signaling or Medium Access Control Control Element (MAC CE) or Layer 1 signaling or other newly defined perception signaling; the signaling transmission between the perception network function and the terminal may be through Non-Access-Stratum (NAS) signaling (forwarded via AMF) or through RRC signaling or MAC CE or Layer 1 signaling or other newly defined perception signaling; the interaction between the perception network function and the base station may be forwarded to the wireless access network through the N2 interface by the AMF; or the core network perception network function may send it to the UPF, and the UPF may send it to the wireless access network through the N3 interface; or it may be sent to the wireless access network (such as a base station) through a newly defined interface; the signaling transmission between wireless access network devices may be through the Xn interface.

[0065] In some embodiments, the perception network function may also be called a perception network element or a perception management function (Sensing Management Function, Sensing MF), which may be located on the RAN side or the core network side. It refers to a network node in the core network or RAN responsible for at least one function such as perception request processing, perception resource scheduling, perception information interaction, and perception data processing. It may be based on an upgrade of the AMF or LMF in the mobile communication network, or it may be another network node or a newly defined network node. Specifically, the functional characteristics of the perception network function / perception network element may include at least one of the following:

[0066] Target information is exchanged with a wireless signal sending device or a wireless signal measuring device (including a target terminal or a serving base station of the target terminal or a base station associated with a target area), wherein the target information includes a perception processing request, a perception capability, perception assistance data, a perception measurement quantity type, a perception resource configuration information, etc., to obtain the value of the target perception result or the perception measurement quantity (uplink measurement quantity or downlink measurement quantity) sent by the wireless signal measuring device; wherein the wireless signal can also be referred to as a perception signal.

[0067] The perception method to be used is determined based on factors such as the type of perception service, perception service consumer information, required perception service quality (QoS) requirement information, the perception capability of the wireless signal sending device, and the perception capability of the wireless signal measuring device. The perception method may include: wireless access network device A sends and wireless access network device B receives, or the wireless access network device sends and the terminal receives, or the wireless access network device A sends and receives by itself, or the terminal sends and the wireless access network device receives, or the terminal sends and receives by itself, or terminal A sends and terminal B receives, etc.

[0068] The perception device serving the perception service is determined based on factors such as the type of perception service, information about the perception service consumer, required perception QoS requirement information, the perception capability of the wireless signal sending device, and the perception capability of the wireless signal measuring device. The perception device includes a wireless signal sending device or a wireless signal measuring device.

[0069] Manage the overall coordination and scheduling of resources required for sensing services, such as configuring sensing resources for wireless access network devices or terminals;

[0070] Data processing or calculation is performed on the values ​​of the perceived measurement quantity to obtain the perceived result. The perceived result can also be verified and the perception accuracy can be estimated.

[0071] In some embodiments, radars can be categorized as monostatic and bistatic / multistatic, depending on whether the transmitter and receiver are separated. Bistatic radars generally require a significant distance between the transmitting and receiving antennas, comparable to the radar's operating range. Exo-radiation radars are a special case of bistatic radars. They utilize relevant electromagnetic wave detection theory and signal processing techniques to acquire non-cooperative electromagnetic signals transmitted by a third party (e.g., a communication base station) to detect, locate, track, and identify targets. These radars are also known as passive radars, bistatic / multistatic passive radars, passive radars, non-cooperative illuminating source radars, or non-cooperative passive detection systems.

[0072] The calculation of the bistatic radar perception result is generally based on the reference channel (direct path) signal and the monitoring channel (reflection path) signal. The typical bistatic radar architecture diagram is shown in Figure 3. T is the distance from the signal transmitter (Tx) to the target, RR is the distance from the signal receiving end (Tx) to the target, L is the baseline distance, θ T is the angle of the target relative to the signal transmitter, θ R (θ R1 ,θ R2 ) is the angle of the target relative to the signal receiving end, and β is the bistatic angle.

[0073] In some embodiments, for common distance, Doppler, or speed measurements in perception measurements, measurement ambiguity may occur when the signal resource configuration does not meet the requirements. For example, for single-base radar perception, the relationship between the maximum unambiguous distance, Doppler, or speed and the signal resource configuration is:

[0074] If the speed direction is considered, the time domain resource interval satisfies ΔT≤1 / (2|f dmax |) or ΔT≤c / (4f c |v max |); If the time domain resource interval in the direction of speed is not considered and satisfies ΔT≤1 / f dmax Or ΔT≤c / (2f c v max ), where f dmax is the maximum unambiguous Doppler, v max is the maximum unambiguous velocity, f c is the carrier frequency and c is the speed of light.

[0075] Frequency domain resource spacing satisfies Δf≤1 / τ max Or Δf≤c / (2R max ), where τ max is the maximum unambiguous delay, R max is the maximum unambiguous distance.

[0076] That is to say, when the frequency domain resource interval of the signal exceeds a certain value, ranging ambiguity will occur, and when the time domain resource interval exceeds a certain value, speed measurement / Doppler measurement ambiguity will occur.

[0077] In the following, in conjunction with the accompanying drawings, a measurement information reporting method, a grouping indication method, an apparatus and a device provided by the embodiments of the present application are described in detail through some embodiments and their application scenarios.

[0078] Please refer to FIG4 , which is a flowchart of a measurement information reporting method provided in an embodiment of the present application. As shown in FIG4 , the method includes the following steps:

[0079] Step 401: A first device obtains first information, where the first information includes group indication information, where the group indication information is used to indicate at least one of the following: whether group measurement is required, whether group reporting is required, and a grouping method.

[0080] The first device mentioned above may be a terminal or a network side device.

[0081] The first device obtaining the first information may be the first device receiving the first information sent by the second device, and the second device may be a terminal, a network side device or a core network device.

[0082] The above-mentioned group measurement may be performed in groups according to signal resources, transmitting and receiving antenna ports or beams.

[0083] The above-mentioned group reporting can be grouped according to signal resources, transceiver antenna ports or beams.

[0084] The above-mentioned grouping method can be a measurement grouping method or a reporting grouping method, such as group measurement according to signal resources, group measurement according to transceiver antenna ports, or group measurement according to beams, group reporting according to signal resources, group reporting according to transceiver antenna ports, or group reporting according to beams.

[0085] In some implementations, the grouping method may include at least one of the following:

[0086] Grouping according to the sent sensing signal resources, where the same sensing signal resource can be sent on multiple ports;

[0087] Group by sending signal port;

[0088] Group by receiving antenna port;

[0089] Group by receiver branch;

[0090] Group by receiving channel;

[0091] Group by transmit beam (spatial filter);

[0092] Group by receive beam (spatial filter).

[0093] The above-mentioned perception signal resources may be time domain resources or frequency domain resources, such as dividing a plurality of time domain resources into at least two groups, or dividing a plurality of frequency domain resources into at least two groups.

[0094] Alternatively, the grouping method may be a combination of at least two of the above, such as grouping by transmit-receive beam pairs or grouping by transmit-receive port pairs. The transmit-receive port pairs may be understood as independent sub-channels that can be resolved by the receiving end during channel estimation.

[0095] In the embodiment of the present application, the beam can also be called a spatial filter.

[0096] In some implementations, if group measurement is indicated, group reporting may be required by default; if group reporting is indicated, group measurement may be required by default; if a group mode is indicated, group measurement or group reporting may be required by default.

[0097] Step 402: The first device sends second information corresponding to the grouping indication information, where the second information includes at least one of the following:

[0098] Measurement results, performance indicators.

[0099] The second information corresponding to the grouping indication information may include at least one of the following:

[0100] Where grouped measurements are indicated, the grouped measurement results or perceived indication performance;

[0101] Where indications require group reporting, grouped measurement results or perceived indication performance;

[0102] In the case of an indication grouping method, the measurement results or perceived indication performance corresponding to the grouping method;

[0103] Ungrouped measurements or perceived indication performance where grouped measurements are not required;

[0104] In the case where the indication does not require group reporting, the ungrouped measurement results or perceptions indicate performance.

[0105] The first device sending the second information corresponding to the grouping indication information may be sending the second information corresponding to the grouping indication information to the second device or the third device, and the third device may be a terminal or a network side device.

[0106] The measurement in the embodiments of the present application may be a perception measurement, or a communication measurement, or a communication-perception integrated measurement, that is, the above-mentioned measurement results may be communication measurement results, or perception measurement results, or a synaesthesia integrated measurement result, and the above-mentioned performance indicators may be communication performance indicators, or perception performance indicators, or synaesthesia integrated performance indicators.

[0107] Among them, the perception measurement can be applied to dual-base perception, for example: the first device receives the perception signal sent by the second device and performs measurement to obtain the measurement result, and the first device reports the measurement result group to the second device or the third device. And the above-mentioned first information can be received by the first device from the second device or the third device. In this scenario, the first device and the second device can be terminals or base stations (or TRPs). Specifically, the first device can be a base station and the second device can be a terminal; or the first device can be a terminal and the second device can be a base station; or the first device can be a terminal and the second device can be a base station; or the first device and the second device can be both base stations; or the first device and the second device can be both terminals. The third device can be a core network perception network function or a perception network element, or it can be another base station or a terminal.

[0108] Perception measurement can be applied to single-base perception. For example, a first device sends a perception signal, receives an echo signal, measures it, and obtains a measurement result. The first device then reports the measurement result in packets to a second device. Furthermore, the first information can be received by the first device from the second device. In this scenario, the first device can be a terminal or a base station (or TRP), and the second device can be a core network perception network function or perception network element, or a base station or terminal.

[0109] In the embodiment of the present application, the group indication information is used to indicate at least one of whether group measurement is required, whether group reporting is required, and the grouping mode, and the measurement result or performance indicator corresponding to the group indication information is transmitted. This enables the first device to support flexible measurement or reporting, thereby improving measurement performance. In addition, in the case of group measurement or group reporting, the measurement result or performance indicator can be made more accurate, further improving measurement performance.

[0110] Taking perception measurement as an example, in order to achieve ideal perception performance, during the perception measurement process, the transceiver beams need to point to the perception target or area. In other words, during the perception measurement process, the transceiver beams need to cover the perception target or cover the perception area. Figures 5 and 6 are schematic diagrams of the perception target or area and the corresponding transceiver beams in dual-base perception and single-base perception scenarios, respectively.

[0111] (a) in Figure 5 indicates that the beam covers a specific area, (b) in Figure 5 indicates that the beam covers a specific target, (a) in Figure 6 indicates that the beam covers a specific area, (b) in Figure 6 indicates that the beam covers a specific target.

[0112] As shown in the scenarios of Figures 5 and 6, the perception measurement results corresponding to different beams may be different, and different beams may be associated with different signal resources or ports. In an embodiment of the present application, the perception measurement results can be grouped and reported according to the sending signal configuration, receiving port configuration, or transceiver beamforming in different perception scenarios. Among them, the perception signal received and measured by the first device is a signal used for perception measurement, which may include at least one of the following:

[0113] Dedicated sensing signals, such as those generated based on chirp or frequency modulated continuous wave (FMCW) signals, or those generated based on pseudo-random (PN) sequences, ZC sequences, or other constant envelope zero auto-correlation (CAZAC) sequences;

[0114] Reference signals, such as Demodulation Reference Signal (DMRS), Channel State Information Reference Signal (CSI-RS), Sounding Reference Signal (SRS), or Positioning Reference Signal (PRS);

[0115] Synchronization signals, such as Primary Synchronization Signal (PSS) or Secondary Synchronization Signal (SSS);

[0116] Signals that carry communication data, such as the Physical Downlink Shared Channel (PDSCH), Physical Uplink Shared Channel (PUSCH), Physical Downlink Control Channel (PDCCH), or Physical Uplink Control Channel (PUCCH) signals.

[0117] Furthermore, the above signal can be a single-port signal or a multi-port signal.

[0118] In the embodiment of the present application, the above signal may be referred to as a first signal.

[0119] As an optional implementation manner, the grouping indication information includes at least one of the following:

[0120] Signal resource grouping indication information, transmit antenna port grouping indication information, receive antenna port grouping indication information, transmit beam grouping indication information, receive beam grouping indication information, and combined grouping indication information;

[0121] The combined group indication information is used to indicate the grouping of a combination of at least two of the transmitting antenna port, the receiving antenna port, the transmitting beam, the receiving beam, and the signal resource.

[0122] The signal resource grouping indication information is used to indicate whether group measurement or group reporting is required according to signal resources, or to indicate whether the grouping method is grouping according to signal resources.

[0123] In some embodiments, the signal resource grouping indication information is used to indicate at least one signal resource group, each signal resource group including one or more signal resources. For example, each signal resource group includes at least one signal resource, and independent measurements are performed on different signal resource groups to obtain measurement results. In some embodiments, each signal resource group includes only one signal resource, i.e., each signal resource is independently measured to obtain a measurement result; or, each signal resource group includes all signal resources, i.e., each signal resource is jointly measured to obtain a measurement result.

[0124] In some embodiments, the signal resource grouping indication information includes first quasi co-location (QCL) information, where the first QCL information is used to indicate that signal resources satisfying the QCL relationship are a signal resource group. The first QCL information may be QCL information in the signal resource configuration information, where the QCL information indicates signal grouping information, for example, signal resources satisfying the QCL type D (QCL-TypeD) relationship are grouped together, that is, signal resources using the same transmit or receive beam are grouped together. QCL-TypeD is merely an example, for example, signal resources with a QCL-TypeD relationship may also be divided into different groups. The first QCL information may implicitly display signal resource grouping, thereby saving information overhead.

[0125] The signal resource grouping indication information can be used to implement group measurement or reporting based on signal resources, thereby improving the flexibility of measurement or reporting.

[0126] The transmitting antenna port grouping indication information may indicate whether group measurement or group reporting needs to be performed according to the transmitting antenna port, or may be used to indicate that the grouping mode is grouping according to the transmitting antenna port.

[0127] In some embodiments, the transmit antenna port grouping indication information is used to indicate at least one transmit antenna port group, each transmit antenna port group including one or more transmit antenna ports. For example, if the measured signal is a multi-port signal, each resource group includes at least one transmit antenna port (also referred to as a signal port), and independent measurements are performed on different transmit antenna port groups to obtain measurement results. In some embodiments, each antenna port group includes only one antenna port, i.e., each transmit antenna port of the signal is independently measured to obtain a measurement result; or, each transmit antenna port group includes only all signal ports, i.e., each transmit antenna port of the signal is jointly measured to obtain a measurement result.

[0128] In some embodiments, the above-mentioned transmitting antenna port grouping indication information includes second QCL information, and the second QCL information is used to indicate that the transmitting antenna ports that satisfy the QCL relationship are a transmitting antenna port group. The above-mentioned second QCL information may be the QCL information of the transmitting antenna port. For example: the QCL information of each transmitting antenna port of the signal indicates the grouping information of the signal, that is, when the signal is a multi-port signal, the QCL information of each transmitting antenna port is indicated in the signal configuration information. For example, the transmitting antenna ports that satisfy the QCL-TypeD relationship are a group, that is, the transmitting antenna ports using the same transmitting or receiving beam are a group. Similarly, for illustration purposes only, the transmitting antenna ports that satisfy the QCL-TypeD relationship can also be divided into different groups.

[0129] By sending the antenna port grouping indication information, measurement or reporting based on the sending antenna port groups can be achieved, thereby improving the flexibility of measurement or reporting.

[0130] The above-mentioned receiving antenna port grouping indication information can indicate whether group measurement or group reporting is required according to the receiving antenna port, or is used to indicate that the grouping method is grouping according to the receiving antenna port. For example: the first device supports receiving signals through multiple antenna ports, and indicates grouping according to the receiving antenna port through the receiving antenna port grouping indication information. In some embodiments, each receiving antenna port group includes only one receiving antenna port, that is, the receiving end independently measures the received signal of each receiving antenna port to obtain the measurement result; or each receiving antenna port group includes only all receiving antenna ports, that is, the receiving end performs a joint measurement on the received signal of each receiving antenna port to obtain the measurement result.

[0131] It should be noted that the receiving antenna port can also be understood as a receiving channel, a receiving branch, etc., and the signals received through different receiving antenna ports are distinguishable for baseband processing of the first device.

[0132] The above-mentioned receiving antenna port grouping indication information can be used to implement measurement or reporting based on the receiving antenna port grouping, thereby improving the flexibility of measurement or reporting.

[0133] The transmit beam grouping indication information may indicate whether group measurement or reporting is required by transmit beam, or may be used to indicate that the grouping method is to group by transmit beam. For example, the transmit beam grouping indication information may indicate at least one transmit beam group, each transmit beam group including at least one transmit beam, and independent measurements are performed on different transmit beam groups to obtain measurement results.

[0134] By sending the beam grouping indication information, it is possible to implement measurement or reporting by sending beam grouping, thereby improving the flexibility of measurement or reporting.

[0135] The receive beam grouping indication information may indicate whether group measurement or reporting is required by receive beam, or may indicate whether grouping is by receive beam. For example, the receive beam grouping indication information may indicate at least one receive beam group, each receive beam group including at least one receive beam, and independent measurements are performed on different receive beam groups to obtain measurement results.

[0136] The above-mentioned receiving beam grouping indication information can be used to implement receiving beam grouping measurement or reporting, thereby improving the flexibility of measurement or reporting.

[0137] The above-mentioned combined grouping indication information may indicate whether combined grouping measurement or grouping reporting is required according to multiple dimensions, or may be used to indicate that the grouping mode is combined grouping.

[0138] The above-mentioned combined group indication information can realize the combination of at least two items as a group by indicating the identifiers, indexes and other indication information of at least two of the transmitting antenna port, receiving antenna port, transmitting beam, receiving beam and signal resources. For example, the combined group indication information indicates the identifier of a transmitting antenna port and the identifier of a receiving antenna port to realize the group indication of the combination of the transmitting antenna port and the receiving antenna port. For another example, the combined group indication information indicates the index of a transmitting beam and the index of a receiving beam to realize the group indication of the combination of the transmitting antenna port and the receiving antenna port.

[0139] Specifically, the combined grouping indication information may include at least one of the following:

[0140] Grouping indication information of the combination of transmitting antenna ports and receiving antenna ports;

[0141] Grouping indication information of the combination of transmit beam and receive beam;

[0142] Grouping indication information of signal resource and receiving antenna port combinations;

[0143] Grouping indication information of signal resources and receive beam combinations.

[0144] The grouping indication information of the above-mentioned combination of the transmitting antenna port and the receiving antenna port may indicate whether to perform group measurement or reporting according to the combination of the transmitting antenna port and the receiving antenna port, wherein the specific grouping manner of grouping the combination of the transmitting antenna port and the receiving antenna port may be directly indicated in the combined grouping indication information, or may be determined by the first device based on a protocol or pre-configuration. For example, when indicating that group measurement or reporting is performed according to the combination of the transmitting antenna port and the receiving antenna port, the first device performs group measurement or reporting based on the protocol agreement or pre-configured combination of the transmitting antenna port and the receiving antenna port. Or the above-mentioned combined grouping indication information indicates that the grouping manner is grouping of the transmitting antenna port and the receiving antenna port combination. The transmitting antenna port and the receiving antenna port combination may also be referred to as a transmitting antenna port and a receiving antenna port pair. For example, each antenna port pair includes at least one transmitting-receiving antenna port pair, and different transmitting-receiving port pairs are independently measured to obtain measurement results. For example, the first signal configured by the network side device supports two ports for transmission, which are recorded as {TxPort#0, TxPort#1}, and the first device supports four antenna ports for reception, which are recorded as {RxPort#0, RxPort#1, RxPort#2, RxPort#3}. Then the transmit-receive port pair may include:

[0145] Group0: {TxPort#0-RxPort#0,TxPort#0-RxPort#1,TxPort#0-RxPort#2,TxPort#0-RxPort#3};

[0146] Group1: {TxPort#1-RxPort#0, TxPort#1-RxPort#1, TxPort#1-RxPort#2, TxPort#1-RxPort#3}.

[0147] In some embodiments, each transmit-receive port pair may include a transmit antenna port and a receive antenna port, such as Group 0 includes four transmit-receive port pairs, namely TxPort#0-RxPort#0, TxPort#0-RxPort#1, TxPort#0-RxPort#2, and TxPort#0-RxPort#3; Group 1 includes four transmit-receive port pairs, namely TxPort#1-RxPort#0, TxPort#1-RxPort#1, TxPort#1-RxPort#2, and TxPort#1-RxPort#3.

[0148] In some implementations, each transmit-receive port pair may include one transmit antenna port and multiple receive antenna ports. For example, Group 0 and Group 1 above represent two transmit-receive port pairs, respectively. This allows joint measurement of one transmit antenna port through multiple receive antenna ports.

[0149] The grouping indication information of the above-mentioned transmit beam and receive beam combination may indicate whether group measurement or reporting is performed according to the transmit beam and receive beam combination, or indicate that the grouping method is grouping of the transmit beam and receive beam combination. The transmit beam and receive beam combination may also be referred to as a transmit beam and receive beam pair. In some embodiments, the grouping indication information of the above-mentioned transmit beam and receive beam combination may indicate at least one transmit-receive beam pair, and different transmit-receive beam pairs are independently measured to obtain measurement results. Different transmit ports or signal resources may be associated with different transmit beams, or may be associated with the same transmit beam; different receive antenna ports may be associated with different receive beams, or may be associated with the same receive beam.

[0150] In some embodiments, a receive antenna port or receive beam can be associated with a signal resource, signal port, or transmit beam. That is, the corresponding receive antenna port or receive beam can be determined by indicating the signal resource, signal port, or transmit beam. For example, in FIG5(b), through beam training or other historical measurement information, the receiving device determines that the receive beam corresponding to transmit beam TxBeam#1 is RxBeam#1, and the receive beams corresponding to transmit beams TxBeam#2 and TxBeam#3 are RxBeam#2. In this case, if the transmit beams are grouped as Group 0: {TxBeam#1} and Group 1: {TxBeam#2, TxBeam#3}, the receiving device can be considered to have obtained the following beam pair groupings: Group 0: {TxBeam#1-RxBeam#1} and Group 1: {TxBeam#2-RxBeam#2, TxBeam#3-RxBeam#2}.

[0151] The grouping indication information of the above-mentioned signal resource and receiving antenna port combination may indicate whether to perform group measurement or reporting according to the signal resource and receiving antenna port combination, or indicate that the grouping method is the grouping of the signal resource and receiving antenna port combination. In some embodiments, the grouping indication information of the above-mentioned signal resource and receiving antenna port combination may indicate at least one signal resource-receiving antenna port pair, and different signal resource-receiving port pairs are independently measured to obtain measurement results. For example: the network side device configures 2 signal resources for perception measurement, recorded as {Resource#0, Resource#1}, and the first device supports 4 antenna port reception, recorded as {RxPort#0, RxPort#1, RxPort#2, RxPort#3}. The transmit-receive antenna port pairs may include: {Resource#0-RxPort#0, Resource#0-RxPort#1, Resource#0-RxPort#2, Resource#0-RxPort#3}, {Resource#1-RxPort#0, Resource#1-RxPort#1, Resource#1-RxPort#2, Resource#1-RxPort#3}. This indicates that for each signal resource, the first device supports joint processing and reporting of received signals from four receive antenna ports.

[0152] The grouping indication information for the signal resource and receive beam combination may indicate whether group measurement or reporting is performed based on the signal resource and receive beam combination, or may indicate whether the grouping method is grouping based on the signal resource and receive beam combination. In some embodiments, the grouping indication information for the signal resource and receive beam combination may indicate at least one signal resource-receive beam pair, and measurement results are obtained by performing independent measurements on different signal resource-receive beam pairs.

[0153] The above-mentioned combined grouping indication information can be used to implement grouped measurement or reporting in a combined manner, thereby making the measurement or reporting more accurate.

[0272] The above-mentioned perception indicators related to the received power may include: a first indicator, which is used to indicate the received power of the perception target association path.

[0273] In some embodiments, the first indicator may be a linear average (in W) of the received power of the path associated with the perception target in the channel response obtained by measuring the first signal on the resource unit carrying the first signal, where the resource unit is a time domain or frequency domain resource unit. In this way, the received power can be made more accurate and reliable by the linear average. It should be noted that the embodiments of the present application do not limit the received power to a linear average. For example, in some embodiments, the median received power, the minimum received power, or the maximum received power may also be taken.

[0274] The above-mentioned first signal is a signal measured by the first device, such as a dedicated signal for sensing services, or a communication signal such as a reference signal, a synchronization signal, etc.

[0275] The aforementioned perceptual indicators related to interference or noise power include at least one of the following:

[0276] a second indicator, where the second indicator is the sum of a first linear average and a second linear average, where the first linear average is the linear average of the powers 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 second linear average is the linear average of the interference or noise power from signals other than the first signal on the first resource; or, the second indicator is equal to the difference between the total received power and the first indicator, where the total received power is the total received power of the first device on the target resource;

[0277] a third indicator, where the third indicator is a linear average of interference or noise power from signals other than the first signal on the second resource, or the third indicator is equal to a difference between a total received power and a received power of the first signal, where the total received power is a total received power of the first device on the target resource;

[0279] Among them, the first indicator is used to indicate the receiving power of the path associated with the perception target of the first signal, the target resource is the transmission resource of the first signal, the first resource includes the target resource or at least one resource other than the target resource, and the second resource includes the target resource or at least one resource other than the target resource.

[0280] The above-mentioned other paths may be all or part of the paths in the first signal except the path associated with the above-mentioned perception target.

[0281] The other signals other than the above-mentioned first signal may refer to all or part of the signals other than the first signal detected by the first device on the first resource.

[0282] The first resource includes the target resource or at least one resource other than the target resource, which means that the first resource includes at least one of the following:

[0283] a target resource, and at least one resource other than the target resource.

[0284] The second resource includes the target resource or at least one resource other than the target resource, which means that the second resource includes at least one of the following:

[0285] a target resource, and at least one resource other than the target resource.

[0286] Among them, the above-mentioned at least one resource other than the target resource may refer to at least one resource other than the target resource among the resources that the first device needs to detect or receive signals, such as resources configured by high-level signaling or resources that the first device predetermines need to detect or receive signals.

[0287] The above-mentioned interference or noise power includes the sum of interference power and noise power, interference power or noise power.

[0288] The total received power of the first device on the target resource may include the received power of signals of the serving cell and the non-serving cell on the target resource, adjacent channel interference power, and thermal noise power. The total received power may also be a linear average (in W) of the total received power of the first device on the target resource.

[0289] The power corresponding to the received signal strength indication (RSSI) of the first device on the first resource may be total received power = RSSI * K1, where K1 is a coefficient and may be a protocol agreement or network-side configuration. In some embodiments, the power corresponding to the RSSI may also be RSSI, i.e., total received power = RSSI.

[0290] The received power of the first signal refers to the reference signal received power (RSRP) of the first signal.

[0291] The above-mentioned second indicator is equal to the difference between the total received power and the first indicator, which can be expressed as second indicator = total received power - first indicator.

[0292] The third indicator equal to the difference between the total received power and the received power of the first signal can be expressed as third indicator = total received power - first signal received power.

[0293] The fourth indicator equal to the difference between the received power of the first signal and the first indicator can be expressed as fourth indicator=received power of the first signal-first indicator.

[0294] In the above embodiment, the second indicator can be used to consider interference or noise of paths other than the path associated with the perception target and signals other than the first signal when determining measurement switching, which can make measurement switching more reliable.

[0295] In the above implementation, the third indicator can be used to consider interference or noise of other signals besides the first signal when determining measurement switching, which can make the measurement switching more reliable.

[0296] In the above implementation, the fourth indicator can be used to consider the power of other paths except the path associated with the sensing target when determining the measurement switching, which can make the measurement switching more reliable.

[0297] The above-mentioned perception indicator related to the received power and also related to the interference or noise power means that the perception indicator is related to both the received power and the interference or noise power.

[0298] In some embodiments, the perception indicator related to received power and also related to interference or noise power includes at least one of the following:

[0299] a fifth index, the fifth index being equal to a quotient obtained by dividing the first index by the second index;

[0300] a sixth index, the sixth index being equal to a quotient obtained by dividing the first index by the third index;

[0301] a seventh index, the seventh index being equal to a quotient obtained by dividing the first index by the fourth index;

[0302] an eighth indicator, the eighth indicator being equal to the product of a quotient obtained by dividing the first indicator by the total received power and a target coefficient;

[0303] The total received power is the total received power of the first device on the target resource.

[0304] The first, second, third, and fourth indicators mentioned above refer to the above-mentioned embodiments and are not described in detail here. It should be noted that, when at least one of the fifth, sixth, seventh, and eighth indicators is included, the perception-related indicators in the embodiments of the present application may include or exclude the first, second, third, and fourth indicators.

[0305] The above target coefficient can be expressed as K2, such as the eighth indicator = K2*first indicator / total received power, K2 is a coefficient, and K2 can be specifically agreed upon in the protocol or configured on the network side.

[0306] In this implementation, by using the fifth indicator, the sixth indicator, the seventh indicator or the eighth indicator, it is possible to take the received power and the interference or noise into consideration when determining the measurement switching, so that the measurement switching is more reliable.

[0307] In some implementations, the aforementioned perception indicator related to received power and also related to interference or noise power may further include at least one of the following:

[0308] Indicators related to perceived SINR, indicators related to perceived SNR, indicators related to perceived signal-to-interference ratio (SIR), and indicators related to perceived RSRQ.

[0309] In some embodiments, the path associated with the sensory target satisfies at least one of the following:

[0310] The parameter meets the first preset threshold, or the parameter is within the first preset range;

[0311] The parameters meet the preset modulation rules;

[0312] The parameter difference with the first arrival path meets the second preset threshold, or the parameter difference with the first arrival path is within a second preset range;

[0313] The parameter difference with the reference path meets a third preset threshold, or the parameter difference with the reference path is within a third preset interval.

[0314] The above parameters may include at least one of the following:

[0315] Amplitude, power, intensity, energy, phase, Doppler, delay, angle;

[0316] The above parameter difference may include at least one of the following:

[0317] Amplitude difference, power difference, intensity difference, energy difference, phase difference, Doppler difference, delay difference, and angle difference.

[0318] The first preset threshold, the first preset interval range, the second preset threshold, the second preset interval range, the third preset threshold, and the third preset interval range may be agreed upon by the protocol or configured on the network side, or these preset thresholds or preset interval ranges are determined by the receiving device based on prior perception information or perception requirements. The above-mentioned parameter satisfying the first preset threshold may mean that the parameter exceeds or is equal to the first preset threshold, the above-mentioned parameter difference with the first-reaching path satisfies the second preset threshold may mean that the parameter difference with the first-reaching path exceeds or is equal to the second preset threshold, and the above-mentioned parameter difference with the reference path satisfies the third preset threshold may mean that the parameter difference with the reference path exceeds or is equal to the third preset threshold.

[0319] For example: if the perception service is moving target detection, it is necessary to detect the path with Doppler greater than zero as the path associated with the perception target; or for the traffic scene perception target is a car, the default vehicle speed is 40km / h to 120km / h, then the path within the corresponding speed range (Doppler range) is detected as the path associated with the perception target; or the distance between the perception target area and the perception signal transceiver needs to meet specific requirements, then the path within the corresponding time delay range is detected as the path associated with the perception target; or if the perception service is respiratory monitoring, the corresponding normal respiratory rate can be judged according to the person's gender and age (for example, 15 to 30 times / minute can be used as perception prior information, and the corresponding Doppler range can be calculated, 0.25 to 0.5Hz).

[0320] The first arrival path may be a line-of-sight (LOS) path, specifically, the path of the first signal that first reaches the receiver. The reference path may be a path reflected by a known target, such as a reconfigurable intelligence surface (RIS), backscatter, or other known passive targets.

[0321] The preset modulation rule may be a protocol agreement or a network configuration. The specific modulation rule is a modulation rule of a tag or backscatter device or RIS, that is, the path associated with the sensing target may be a path modulated and reflected by the tag or backscatter device or RIS.

[0322] In one of the above optional implementations, the path associated with the perceived target can be determined in multiple ways, which can not only improve the flexibility of determining the path associated with the perceived target, but also improve the accuracy of determining the path associated with the perceived target based on multiple ways.

[0323] In some implementations, before determining the path associated with the perceived target, a path set may be determined. The path set includes path(s) whose amplitude, power, intensity, or energy exceeds a certain threshold. As shown in FIG7 , the path set includes paths 0, 1, 2, and 3. The path associated with the perceived target is then determined based on at least one of the above items in the path set to reduce computational complexity.

[0324] The following example illustrates the calculation of indicators in the embodiment of the present application through an example. It should be noted that the calculation of each indicator in the embodiment of the present application is not limited, and the following example is only an example.

[0325] The calculation method 1 of the first indicator is as follows:

[0326] The first device (such as a terminal) performs channel estimation based on the transmitted first signal X(k) and the received signal Y(k) corresponding to the first signal to obtain a channel response (Channel Response) H(k) = Y(k) / X(k), where k = 0, 1, 2, ..., K-1 represents the resource unit index, and K is the number of resource units. After obtaining the channel response H(k), the first device transforms it into a first dimension and determines the path associated with the perception target in the first dimension. The power of the path associated with the perception target is then calculated as the first indicator. If the path associated with the perception target includes multiple paths, the sum of the powers of the multiple paths is calculated as the first indicator.

[0327] The first dimension includes one of the following:

[0328] Delay dimension;

[0329] Doplevi;

[0330] Azimuth dimension;

[0331] Pitch angle dimension;

[0332] A dimension that combines at least two of the following: delay, Doppler, azimuth, and elevation dimensions. For example, delay-Doppler, delay-Doppler-angle, etc.

[0333] 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.

[0334] Method for determining a path associated with a perception target (referred to as a perception path for short) in a channel response obtained by measuring the first signal:

[0335] Determine the path set. The path set includes all paths whose amplitude, power, intensity, or energy exceeds a certain threshold after the channel response is transformed into the first dimension. For example, in Figure 6, paths 0, 1, 2, and 3 are the path sets. The certain threshold can be set to be above the noise threshold, above the noise interference threshold, or as agreed upon in the protocol. This step (determining the path set) is optional; the next step can be used to determine the path associated with the perceived target.

[0336] A path that satisfies a first condition is selected from the path set or from all paths of the first signal as the path associated with the perception target. The first condition includes at least one of the following:

[0337] The amplitude, power, intensity or energy of the path exceeds the preset threshold or is within the preset range, such as the preset threshold is 5 times the noise threshold;

[0338] The Doppler of the path exceeds the preset threshold or is within the preset range;

[0339] The path delay exceeds the preset threshold or is within the preset range;

[0340] The angle of the path exceeds the preset threshold or is within the preset range;

[0341] The difference between the amplitude / power / intensity / energy of the path and the first-reach path (e.g., LOS path) or the reference path exceeds a preset threshold or is within a preset range. The reference path may be a path reflected by a known target (e.g., RIS / Backscatter / other known passive targets, etc.);

[0342] The Doppler difference between the path and the first arrival path (such as the LOS path) or the reference path exceeds a preset threshold or is within a preset range;

[0343] The delay difference between the first arrival path (such as the LOS path) or the reference path exceeds the preset threshold or is within the preset range;

[0344] The angle difference between the first arrival path (e.g., LOS path) or the reference path exceeds a preset threshold or is within a preset range;

[0345] The amplitude, power, intensity, energy, or phase of the path satisfies a specific modulation rule. The specific modulation rule is the modulation rule of the tag / backscatter device or RIS. That is, the path associated with the perceived target may be a path modulated and reflected by the tag / backscatter device or RIS.

[0346] The above-mentioned first conditions may also be based on statistical results over a period of time; for example, the ratio of the above-mentioned indicators (such as the Doppler of the path, the time delay of the path, etc.) exceeding a preset threshold or being within a preset range in a preset time window reaches a preset ratio, or the number of times the above-mentioned indicators (such as the Doppler of the path, the time delay of the path, etc.) exceed a preset threshold or are within a preset range in a preset time window reaches a preset number of times;

[0347] The preset threshold or preset interval is sent by another device to the receiving device and is determined by the other device based on prior perception information or perception requirements. Alternatively, the preset threshold or preset interval may be a protocol agreement, or the preset threshold or preset interval is determined by the receiving device based on prior perception information or perception requirements.

[0348] The priori perception information or perception requirements include the following information:

[0349] Perception services or perception service types, such as detecting the presence of a target, positioning, speed detection, distance detection, angle detection, acceleration detection, material analysis, component analysis, shape detection, classification, radar cross section RCS (Radar Cross Section, RCS) detection, polarization scattering characteristic detection, fall detection, intrusion detection, population statistics, indoor positioning, gesture recognition, lip reading recognition, gait recognition, expression recognition, facial recognition, respiration monitoring, heart rate monitoring, pulse monitoring, humidity / brightness / temperature / atmospheric pressure monitoring, air quality monitoring, weather condition monitoring, environmental reconstruction, topography, building / vegetation distribution detection, pedestrian or vehicle flow detection, crowd density, vehicle density detection, etc.; the perception service type can be to classify multiple different perception services according to certain characteristics, for example, according to function, it can be divided into detection-type perception services (for example, including intrusion detection, fall detection), parameter estimation-type perception services (distance, angle, speed calculation), recognition-type perception services (motion recognition, identity recognition), etc., and can also be divided according to the range of perception (close-range perception, medium-range perception, long-range perception), according to the degree of perception fineness (coarse-grained perception, fine force perception, etc.), according to power consumption / energy consumption, according to resource occupancy, etc. If the sensing service is respiratory monitoring, the corresponding normal respiratory rate can be determined based on the person's gender and age (for example, male: 13-21 breaths / minute, female: 15-20 breaths / minute; adult: 12-20 breaths / minute, child: approximately 30-40 breaths / minute), which can be used as perception prior information;

[0350] Perception target area: refers to the location area of ​​the perception object, or the location area where imaging or environmental reconstruction is required; for example, the preset interval range of the time delay of the path associated with the perception target is determined based on the approximate location / distance of the perception object;

[0351] Perception object type: Classifies the perception object according to its possible motion characteristics. Each perception object type contains information such as the typical perception object's motion speed range, motion acceleration range, and typical RCS range.

[0352] The number of perceived targets; for example, the camera perception result is used as a perception prior information to obtain the number of perceived targets.

[0353] For example, in FIG7 , paths 0, 1, 2, and 3 are paths in the path set, where paths 2 and 3 are perception paths that meet the first condition (eg, their delays meet a preset threshold), and paths 0 and 1 are paths associated with other scatterers.

[0354] 7 is a schematic diagram of multipath of the channel response in the first dimension (delay dimension, Doppler dimension, azimuth dimension, or elevation angle dimension), wherein the horizontal axis is the first dimension and the vertical axis is the normalized amplitude, power, intensity or energy.

[0355] For frequency range 1, the reference point for the first metric can be the antenna connector of a receiving device, such as a terminal. For frequency range 1, if the receiving device has multiple receiving channels, the first metric measured and reported by the receiving device cannot be lower than the metric of any single receiving channel. For frequency range 2, the first metric measured for a particular receiving channel requires measuring the combined signals of the multiple antenna elements corresponding to that receiving channel.

[0356] The calculation method 2 of the first indicator can be as follows:

[0357] When calculating the received power of the path associated with the sensing target, it can also be the power of the path associated with the sensing target in the first dimension and The difference between is taken as the first indicator, where N1 represents the number of paths associated with the perceived target. is the average power of multiple paths outside the path set in the first dimension.

[0358] The calculation method 1 of the received power of the first signal may be as follows:

[0359] The received power of the first signal may be obtained by the receiving device, after obtaining the channel response (Channel Response) H(k), transforming it into the first dimension, determining a path set in the first dimension, and then calculating the power sum of all paths in the path set.

[0360] Method 2 for calculating the received power of the first signal may be as follows:

[0361] The received power of the first signal can also be the sum of the powers of all paths in the path set in the first dimension and , where N2 represents the number of paths in the path set.

[0362] Total received power P total Calculation method:

[0363] Wherein, Y(k) is the received signal corresponding to the first signal, k=0, 1, 2, ..., K-1 represents the resource unit index, and K is the number of resource units.

[0364] The second indicator can be calculated as follows:

[0365] 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 flter1 (k), and then calculate the second indicator:

[0366] 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 amplitude, power, intensity or energy of paths other than the paths associated with the perceptual targets in FIG7 to zero. The channel response H after the first filtering process filter1 (k) does not include noise, interference, or paths associated with non-perceived targets, but only includes paths associated with perceived targets.

[0367] The calculation method 1 of the third indicator can be as follows:

[0368] 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 flter2 (k)=H flter2 (k)X(k). Then the received signal Y(k) is subtracted from the received signal Y after the second filtering process. flter2 (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:

[0369] The second filtering process can be a noise interference suppression process in the first dimension (for example, the amplitude, power, intensity or energy of the paths other than the path set in FIG7 is set 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, but only contains the paths in the path set.

[0370] The calculation method 2 of the third indicator can be as follows:

[0371] According to the average power of multiple paths outside the path set in the first dimension Calculate the third index P σ2 ,Right now Where N represents the number of sampling points in the first dimension.

[0372] It should be noted that if the receiving device determines that there are multiple sensing targets, or the receiving device obtains the number of sensing targets based on prior sensing information or sensing requirements, the following methods are available:

[0373] Method 1: Calculate the perception-related indicators (also called target indicators) for each perception target separately. For example, in Figure 4, the path associated with each perception target is determined separately, and then the perception-related indicators corresponding to each perception target are calculated separately. At this time, when calculating the second indicator corresponding to a perception target (such as perception target A), there are two methods: the second indicator of perception target A = total received power - the first indicator of perception target A; or the second indicator of perception target A = total received power - the first indicator of perception target A - the first indicator of perception target B; (assuming there are two perception targets: A and B). Similarly, there are two ways to calculate the fourth indicator: the fourth indicator of perception target A = 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).

[0374] Method 2: Calculate a perception-related index for multiple perception targets. For example, in Figure 7, determine the paths associated with any perception target, and then determine 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 perception-related index corresponding to the virtual perception target.

[0375] It should be noted that the above calculation method is only an example, and the embodiments of this application do not limit the specific calculation method of the indicator.

That is, the first device considers their associated subchannels to be independent and performs independent measurements and reports on different transmit signal resources or transmit ports. That is, each transmit signal resource or transmit port is measured and reported as a group.

[0419] For example, the network side device is configured to support 4-port transmission of the first signal for perception measurement, recorded as {TxPort#0, TxPort#1, TxPort#2, TxPort#3}, and the first device supports 4 antenna port reception, recorded as {RxPort#0, RxPort#1, RxPort#2, RxPort#3}.

[0420] For each first signal port, the network side device uses different transmission beams to cover different perception areas. For each first signal port, the four receiving antenna ports of the first device use the same receiving beam to receive the first signal of the four ports. At this time, if the grouping is performed by the transmitting antenna port: Group0: {TxPort#0}, Group1: {TxPort#1}, Group2: {TxPort#2}, Group3: {TxPort#3}; then the first device can be considered to have obtained the following transmitting-receiving antenna port pair grouping: Group0: {TxPort#0-RxPort#0, TxPort#0-RxPort#1, TxPort#0-RxPort#2, TxPort#0-RxPort#3}; Group1: {TxPort#1-RxPort#1} Group 2: {TxPort#2-RxPort#0,TxPort#2-RxPort#1,TxPort#1-RxPort#2,TxPort#1-RxPort#3}; Group 3: {TxPort#3-RxPort#0,TxPort#3-RxPort#1,TxPort#3-RxPort#2,TxPort#3-RxPort#3}. That is, for each transmit antenna port, the receiver supports joint processing and reporting of the received signals from four receive antenna ports.

[0421] Among them, an example of a perception reception processing flow can be shown in Figure 9.

[0422] In this embodiment, since each receiving antenna port uses the same receive beam, the sub-channel information obtained by least-squares (LS) channel estimation for different receiving ports on the same transmitting port is similar. For example, after performing channel estimation and clutter suppression on the received data corresponding to Group 0: {TxPort#0-RxPort#0, TxPort#0-RxPort#1, TxPort#0-RxPort#2, TxPort#0-RxPort#3}, the two-dimensional delay-Doppler spectrum information of each sub-channel obtained by two-dimensional FFT calculation is shown in Figure 10. Figure 10 corresponds to the delay-Doppler spectrum information of sub-channels on different receiving ports on the same transmitting port.

[0423] At this point, the target information detected by the sub-channels of the same transmitting port and different receiving ports is similar. Therefore, threshold detection, such as constant false alarm rate (CFAR) detection, can be performed on the delay-Doppler two-dimensional spectra of the sub-channels of the same transmitting port and different receiving ports. This yields four sets of detection results, each of which includes the delay and Doppler information of multiple targets.

[0424] Then, the union of the four groups of detection results is taken and clustering is performed to obtain the joint detection results of the same sending port and different receiving ports, and the number of detected targets and the corresponding delay and Doppler information are determined.

[0425] In addition, based on the delay-Doppler spectrum information of the subchannels of different receiving ports and the delay and Doppler information of multiple targets in the joint detection results, the angle information of multiple targets in the joint detection results can be further calculated. That is, the angle information of the target can be obtained by using the data of the corresponding delay-Doppler spectrum position of each target on each receiving antenna port (receiving channel) and performing angle estimation through methods such as spatial spectrum estimation.

[0426] Furthermore, the target position information, or the distance information between the target and the transmitting device or the receiving device, or the relative speed information of the target can be obtained based on the time delay and angle information of the target.

[0427] Another implementation method is to perform incoherent combining of the delay-Doppler two-dimensional spectra of each receive antenna port. Specifically, the complex data of each delay-Doppler two-dimensional spectrum is modulo-squared and averaged, as shown in Figure 11. Figure 11 shows the incoherent combining of the delay-Doppler spectra of each receive antenna port. Threshold detection is then performed on the result of the incoherent combination to obtain a detection result, including the number of targets and the corresponding delay and Doppler information. In this case, the perceptual performance indicator can be calculated based on the incoherently combined delay-Doppler two-dimensional spectrum.

[0428] The joint detection result includes the target number, as well as at least one of the target's delay, Doppler, angle, position, distance, velocity, and incoherently combined delay-Doppler two-dimensional spectrum, representing the measurement result for Group 0. Similarly, the measurement result for Group 1 can be obtained. For example, a format for reporting measurement results could be: Group 0 identifier: {number of targets X, target 1 position coordinates, target 2 position coordinates, ...}, Group 1 identifier: ...

[0429] Among them, for bistatic sensing, the delay, Doppler, and angle information also include delay difference, Doppler difference, and angle difference information (between the target-associated reflected signal path and the LOS path).

[0430] In bistatic sensing, the distance and position coordinates of the passive sensing target are calculated. For the scenario shown in Figure 3, the calculation method can be as follows:

[0431] The time delay difference information Δτ between the target reflection signal path and the LOS path is obtained based on the measurement of the received signal, and then the distance difference information R is calculated. T +R R -L=c·Δτ, where R T is the distance from the signal sending device (first device) to the sensing target, R R is the distance from the sensing target to the signal receiving device (second device), and L is the distance between the first device and the second device (baseline distance). If the baseline distance L is known, the distances from the first device to the sensing target and from the sensing target to the second device and R can be further calculated. T +R R .

[0432] Furthermore, according to the arrival angle information θ obtained by measuring the received signal R (horizontal arrival angle information), and the above distance difference information, the distance between the perceived target and the second device can be further obtained based on the following formula:

[0433] Based on the distance R between the perceived target and the second device R , arrival angle information θ R , the coordinate information (x0, y0) of the perception target relative to the local coordinate system of the second device can be calculated.

[0434] If three-dimensional space is considered, then the arrival angle information θ obtained by measuring the received signal R1 (horizontal arrival angle information), arrival angle information θ R2 (vertical arrival angle information), and the above distance difference information, the distance between the perceived target and the second device is obtained based on the following formula:

[0435] Based on the distance R between the perceived target and the second device R , arrival angle information θ R1 and θ R2 , the coordinate information (x0, y0, z0) of the perception target relative to the local coordinate system of the second device can be calculated.

[0436] For single-base sensing, the distance information from the transmitting device or receiving device can be calculated directly based on the time delay information τ of the reflected signal path of the sensing target. Then, the target position coordinates are obtained according to the distance information and the arrival angle information.

[0437] The group measurement and reporting based on different first signal resources are similar and will not be described in detail.

[0438] It should be noted that for the dual-base perception scenario, the terminal may also send a first signal based on the first information after receiving the first information, and the base station may receive the signal, measure the measurement result, and send it to the perception network function; or the first signal may be sent and received between base stations, or between terminals; or it may be used for a single-base perception scenario, that is, the base station may send and receive the first signal by itself, or the terminal may send and receive the first signal by itself, and the embodiments of the present application do not limit this.

[0439] Example 2:

[0440] This embodiment mainly describes group measurement based on receiving antenna ports.

[0441] In this embodiment, the first device performs measurements and reports based on different receive antenna ports. The different receive antenna ports receive signals using different receive beams. That is, the first device considers the subchannels associated with different receive antenna ports to be independent and performs independent measurements and reports on the different receive antenna ports. That is, each receive antenna port is measured and reported as a group.

[0442] In this embodiment, since each receiving antenna port uses a different receiving beam, for the same transmitting port, the sub-channel information obtained by LS channel estimation of different receiving ports at the receiving end is different, and the detection results obtained by perception detection based on the sub-channel information of the different receiving ports are usually different.

[0443] For example, the base station configures the first signal for sensing measurement to support single-port transmission, denoted as TxPort#0, and the terminal supports reception on four antenna ports, denoted as {RxPort#0, RxPort#1, RxPort#2, RxPort#3}. The data is then grouped as follows: Group 0: {TxPort#0-RxPort#0}, Group 1: {TxPort#0-RxPort#1}, Group 2: {TxPort#0-RxPort#2}, and Group 3: {TxPort#0-RxPort#3}. After channel estimation and clutter suppression are performed on the corresponding received data, the two-dimensional delay-Doppler spectrum information for each subchannel obtained through a two-dimensional FFT operation is shown in Figure 12. Figure 12 shows the delay-Doppler spectrum information for subchannels with the same transmit port but different receive ports.

[0444] As can be seen, the delay-Doppler spectrum information of the subchannels at different receiving ports on the same transmitting port differs. Therefore, the detection results may contain different information such as the number of targets, delay, and Doppler. Threshold detection, such as CFAR detection, can be performed on the two-dimensional delay-Doppler spectrum of the subchannels at different receiving ports on the same transmitting port to obtain four sets of detection results, each of which includes the delay and Doppler information of multiple targets.

[0445] The number of targets in the detection results corresponding to receiving antenna ports 0-3, as well as at least one of the target's delay, Doppler, distance, velocity information, and delay-Doppler two-dimensional spectrum information, can be used as the measurement results for Groups 0-3, respectively. The subset of spectrum information described in the inventive solution can be, for example, the delay-Doppler spectrum information within the red box in Figure 12, using TxPort#0-RxPort#3 as an example.

[0446] Optionally, the base station may be configured to support multi-port transmission of the first signal used for perception measurement, and multiple transmitting ports may use the same transmitting beam. The receiving end may jointly measure and process the signals of multiple transmitting ports for each receiving beam, that is, for different transmitting ports, the sub-channel information of the same receiving port may be processed and jointly detected to obtain the measurement results, and then grouped and reported according to different receiving ports.

[0447] Alternatively, if every two of the four receive antenna ports use the same receive beam, for example, ports RxPort#0 and RxPort#1 use the same receive beam, and ports RxPort#2 and RxPort#3 use the same receive beam, then the following groups are formed: Group 0: {TxPort#0-RxPort#0, TxPort#0-RxPort#1}, and Group 1: {TxPort#0-RxPort#2, TxPort#0-RxPort#3}. This means that joint detection and reporting is performed for receive antenna ports 0 and 1, and joint detection and reporting is performed for receive antenna ports 2 and 3.

[0448] It should be noted that ports using different transmit or receive beams can also be assigned as a group for joint detection and reporting. For example, in this embodiment, the four receive antenna ports use different beams for reception. Based on the same transmit port and the delay-Doppler spectrum information of the sub-channels of different receive ports in Figure 12, four groups of detection results are obtained. The four groups of detection results (e.g., the number of targets, the delay and Doppler information of the targets) can be merged and reported as a group of measurement results. The merging can be target deduplication. For example, duplicate targets in the four groups of detection results are eliminated based on the delay-Doppler spectrum information, and then the overall number of targets and the corresponding delay and Doppler information are counted as the measurement results.

[0449] For other grouping methods, including those based on port pairs, beams or beam pairs, etc., the grouping measurement and reporting methods can refer to Example 1 or 2 and will not be repeated here.

[0450] The measurement information reporting method provided in the embodiment of the present application has an impact on the perception results obtained in the multi-target perception scenario, and the content and format of the measurement method and the reporting will affect the perception performance. For example, the perception signal receiving device can perform group measurement and reporting according to signal resources, transceiver antenna ports or beams, or can perform joint measurement and reporting. It provides the definition of measurement quantities, calculation of measurement results and reporting methods under different grouping methods. It can be reasonably configured according to the device capabilities and perception scenarios, improve measurement performance and save reporting overhead.
