[0051] 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:

[0052] Table 1

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] Sensing link 1: The base station transmits and receives sensing signals autonomously. In this mode, the base station sends sensing signals and obtains sensing results by receiving the echo of the sensing signals.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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:

[0065] 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.

[0066] 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.

[0067] 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.

[0068] Manage the overall coordination and scheduling of resources required for sensing services, such as configuring sensing resources for wireless access network devices or terminals;

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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:

[0073] 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.

[0074] 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.

[0075] 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 be sent.

[0076] The following, in conjunction with the accompanying drawings, describes in detail a measurement method, a measurement indication method, an apparatus and a device provided by the embodiments of the present application through some embodiments and their application scenarios.

[0077] Please refer to FIG4 , which is a flow chart of a measurement method provided in an embodiment of the present application. As shown in FIG4 , the method includes the following steps:

[0078] Step 401: A first device obtains first beam indication information sent by a second device, where the first beam indication information is used to indicate first beam information of a signal.

[0079] The first device mentioned above may be a terminal or a network side device.

[0080] The above-mentioned second device can be a terminal, a network side device or a core network device.

[0081] The above-mentioned signal is a signal used for measurement. For perception measurement, the above-mentioned signal is a perception signal. For communication measurement, the above-mentioned signal is a communication signal. The perception signal may include at least one of the following:

[0082] 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;

[0083] Reference signals, such as Demodulation Reference Signal (DMRS), Channel State Information Reference Signal (CSI-RS), Sounding Reference Signal (SRS), or Positioning Reference Signal (PRS);

[0084] Synchronization signals, such as Primary Synchronization Signal (PSS) or Secondary Synchronization Signal (SSS);

[0085] 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.

[0086] Furthermore, the above signal can be a single-port signal or a multi-port signal.

[0087] It is understandable that the perception signal and the communication signal may be the same or different. For example, for a synaesthesia integrated service, the perception signal and the communication signal may be the same.

[0088] The first beam information indicated by the above-mentioned first beam indication information refers to the first beam information used by the first device in measurement.

[0089] The first beam information may enable the first device to use an appropriate beam for measurement. Specifically, the first beam information may indicate signal-related beam information such as a transmit beam, a receive beam, a beam scanning rule, and a beam type.

[0090] Step 402: The first device performs measurement based on the first beam information to obtain result information.

[0091] The above-mentioned measurement may be a perception measurement (also referred to as a perception measurement) or a communication measurement or a communication-perception integrated measurement.

[0092] The first device performing measurement based on the first beam information may be that the first device receives the signal based on the first beam information and performs measurement, or the first device measures the signal based on the first beam information.

[0093] The above-mentioned result information may include measurement results or performance indicators, such as perception-related measurement results (also referred to as perception measurement results) or communication measurement results or synaesthesia integration measurement results, perception-related performance indicators (also referred to as perception performance indicators) or communication performance indicators or synaesthesia integration performance indicators.

[0094] The above-mentioned signal may be a signal sent by the above-mentioned second device, or the above-mentioned signal may be a signal sent by the first device.

[0095] For perception measurement, for example: the perception measurement of the embodiment of the present application can be applied to dual-base perception. In this scenario, the first device receives the first beam indication information sent by the second device, the second device sends a perception signal to the first device according to the first beam indication information, and the first device receives the perception signal according to the first beam indication information and performs measurement to obtain a perception measurement result; wherein, the first device and the second device can be base stations (or TRPs) or terminals, such as the second device is a base station and the first device is a terminal; or, the second device is a terminal and the first device is a base station; or, the first device and the second device are both base stations; or, the first device and the second device are both terminals. In addition, in this scenario, the second device can obtain perception requirements from a third device, and the first device can send the perception measurement results to the first device or the third device after obtaining them. The third device can be a core network perception network function or a perception network element.

[0096] For another example: the perception measurement of the embodiment of the present application can be applied to single-base perception. In this scenario, the second device sends first beam indication information to the first device, and the first device sends a perception signal according to the first beam indication information and receives an echo signal for measurement to obtain a perception measurement result; wherein, the second device can be a core network perception network function or a perception network element, and the first device can be a base station (or TRP) or a terminal.

[0097] In some embodiments, in order to achieve ideal perception performance or improve perception performance, during the perception measurement process, the transceiver beams need to point to the perception target or area, or 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.

[0098] (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.

[0099] In the embodiment of the present application, the beam may also be referred to as a spatial filter.

[0100] In this embodiment of the present application, a first device obtains first beam indication information sent by a second device, where the first beam indication information indicates first beam information of a signal. The first device then performs measurement based on the first beam information to obtain measurement result information. Because the first beam indication information indicates the first beam information of the signal, performing measurement based on the first beam information can make it easier to match the beam information with the measurement, thereby improving measurement performance.

[0101] As an optional implementation manner, the first beam information includes at least one of the following:

[0102] Transmit beam, receive beam, beam scanning rule, beam switching rule, beam dwell time, first beam type.

[0103] Among them, the above-mentioned first beam information includes at least one of the following items, which can explicitly or implicitly indicate at least one item included in the above-mentioned first beam information.

[0104] In some embodiments, the above-mentioned transmission beam includes the transmission beam associated with the signal, or an activated transmission beam set, the transmission beam associated with the signal is a beam used to send the signal, and the transmission beam in the activated transmission beam set is used to send the signal.

[0105] The transmit beam associated with the signal can be understood as all receive beams associated with the signal, that is, all transmit beams used to transmit the signal. The beam used to transmit the signal can be understood as the beam that may transmit the signal, that is, these transmit beams are all beams that may transmit the signal; or the beam used to transmit the signal can be understood as the transmit beam among these beams that ultimately transmits the signal.

[0106] The transmission beams in the activated transmission beam set are used to transmit the signals, that is, the transmitting devices of these signals use the transmission beams in the set to transmit the signals.

[0107] The transmission beam associated with the above signal or the activated transmission beam set can realize a one-time indication of the transmission beam of the signal, and no further indication is required for subsequent transmission beam switching or beam scanning, thereby saving indication signaling overhead.

[0108] In some embodiments, the receiving beam includes a receiving beam associated with the signal, or an activated receiving beam set, where the receiving beam associated with the signal is a beam used to receive the signal, and the receiving beams in the activated receiving beam set are used to receive the signal;

[0109] The receive beams associated with the above-mentioned signal can be understood as all receive beams associated with the signal, that is, all receive beams used to send the above-mentioned signal. The beams used to receive the signal can be understood as beams that can be used to receive the above-mentioned signal, that is, these receive beams are all beams that can be used to receive the above-mentioned signal; or the beams used to receive the signal can be understood as the beams among these beams that ultimately receive the above-mentioned signal. The receive beams in the above-mentioned activated receive beam set being used to receive the signal means that the first device uses the receive beams in the set to receive the signal.

[0110] The receiving beam associated with the above signal or the activated receiving beam set can realize a one-time indication of the receiving beam of the signal, and no further indication is required for subsequent receiving beam switching or beam scanning, thereby saving indication signaling overhead.

[0111] In some embodiments, the first device may determine the transmitting and receiving beams based on one of the transmitting beam and the receiving beam, i.e., determine the transmitting and receiving beam pair information. For example, in FIG5 (a), through beam training or other historical measurement information, the first device determines that the best receiving beam corresponding to the transmitting beams Beam#3 and #4 is Beam#2, and the best receiving beam corresponding to the transmitting beams Beam#5 and #6 is Beam#3.

[0112] In some embodiments, the transmission beam includes at least one of the following: a transmission beam that transmits the signal, a transmission beam that is about to transmit the signal, and an activated transmission beam;

[0113] or,

[0114] The receiving beam includes at least one of the following: a receiving beam that is about to receive the signal and an activated receiving beam.

[0115] Among them, the above-mentioned transmission beam that sends the signal refers to the transmission beam that is currently sending the signal, and the above-mentioned transmission beam that is about to send the signal can be the transmission beam that sends the signal within a preset time range in the future, or the transmission beam that sends the signal in subsequent measurements.

[0116] The activated transmission beam may be the transmission beam currently used for measurement.

[0117] Dynamic indication of the transmission beam can be achieved by indicating at least one of the transmission beam for sending the above-mentioned signal, the transmission beam for sending the signal, and the activated transmission beam. For example, the second device dynamically indicates the transmission beam of the signal according to the characteristics of the perceived service, so that real-time beam adjustment can be performed more flexibly during the measurement process. In the scenario of tracking and perceiving the target, dynamic beam indication can ensure perception performance, realize on-demand configuration, and save resources considering the mobility of the target.

[0118] The receiving beam that is about to receive the signal may be a receiving beam that receives signals within a future preset time range, or a receiving beam that receives signals in subsequent measurements. The activated receiving beam may be a receiving beam used in the current measurement.

[0119] Dynamic indication of the receiving beam can be achieved through at least one of the above-mentioned receiving beam that is about to receive the signal and the activated receiving beam. For example, the second device dynamically indicates the receiving beam of the signal according to the characteristics of the perceived service, so that real-time beam adjustment can be performed more flexibly during the measurement process. In the scenario of tracking and perceiving the target, considering the mobility of the target, dynamic beam indication can ensure perception performance, realize on-demand configuration, and save resources.

[0120] Optionally, the method further includes:

[0121] The first device obtains second beam indication information, where the second beam indication information is used to indicate second beam information of the signal, where the second beam information includes at least one of the following:

[0122] the transmit beam associated with the signal, or the activated transmit beam set, the transmit beam associated with the signal is a beam used to transmit the signal, and the transmit beams in the activated transmit beam set are used to transmit the signal; wherein, at least one of the transmit beam that transmits the signal, the transmit beam that is about to transmit the signal, and the activated transmit beams is the transmit beam associated with the signal or the transmit beam in the activated transmit beam set, or the transmit beam corresponding to at least one of the beam scanning rule, the beam switching rule, the beam dwell time, and the first beam type is the transmit beam associated with the signal or the transmit beam in the activated transmit beam set;

[0123] the receive beam associated with the signal, or the activated receive beam set, the receive beam associated with the signal is a beam used to receive the signal, and the receive beams in the activated receive beam set are used to receive the signal; wherein, at least one of the receive beam that is about to receive the signal and the activated receive beams is the receive beam associated with the signal or the receive beam in the activated receive beam set, or the receive beam corresponding to at least one of the beam scanning rule, the beam switching rule, the beam dwell time, and the first beam type is the receive beam associated with the signal or the receive beam in the activated receive beam set;

[0124] The second beam type, the beam type of at least one of the transmitting beam that sends the signal, the transmitting beam that is about to send the signal, and the activated transmitting beam is the second beam type, or the beam type of at least one of the receiving beam that is about to receive the signal and the activated receiving beam is the second beam type, or the beam type of the beam corresponding to at least one of the beam scanning rule, the beam switching rule, and the beam dwell time is the second beam type.

[0125] Among them, the above-mentioned signal-associated transmit beams, signal-associated receive beams, activated transmit beam sets and activated receive beam sets refer to the corresponding descriptions of the above-mentioned implementation methods and are not repeated here.

[0126] Obtaining the above-mentioned second beam indication information means receiving the above-mentioned second beam indication information before receiving the above-mentioned first beam indication information. For example: the signal-associated transmission beam or the activated transmission beam set is first indicated through the second beam indication information, and then the transmission beam, beam scanning rules, beam switching rules, beam dwell time, and first beam type are indicated through the above-mentioned first beam indication information to realize that the transmission beam, beam scanning rules, beam switching rules, beam dwell time, and the transmission beam corresponding to the first beam type belong to the signal-associated transmission beam or the activated transmission beam set, so as to improve the indication accuracy of the transmission beam, beam scanning rules, beam switching rules, beam dwell time, and first beam type. For example, when the beam switching rule indicates beam switching, the first device determines to perform beam switching on the transmit beam associated with the above signal or the activated transmit beam set based on the above second beam indication information and the first beam indication information; for another example, when the first beam indication information indicates the beam dwell time, the first device determines the transmit beam associated with the above signal or the dwell time of the beam in the activated transmit beam set based on the above second beam indication information and the first beam indication information, and then determines the beam used at each time; for another example, when the first beam indication information indicates the first beam type, the first device determines the transmit beam associated with the above signal or the transmit beam of the first beam type in the activated transmit beam set.

[0127] For another example: the signal-associated receiving beam or the activated receiving beam set is first indicated through the second beam indication information, and then the receiving beam, beam scanning rule, beam switching rule, beam dwell time, and first beam type are indicated through the above-mentioned first beam indication information to ensure that the receiving beam, beam scanning rule, beam switching rule, beam dwell time, and the receiving beam corresponding to the first beam type belong to the signal-associated receiving beam or the activated receiving beam set, so as to improve the indication accuracy of the receiving beam, beam scanning rule, beam switching rule, beam dwell time, and first beam type.

[0128] For another example: the second beam type is first indicated through the second beam indication information, and then the transmitting beam, receiving beam, beam scanning rule, beam switching rule, and beam dwell time are indicated through the above-mentioned first beam indication information, so as to realize that the beam type of the beam corresponding to the transmitting beam, receiving beam, beam scanning rule, beam switching rule, and beam dwell time belongs to the second beam type, so as to improve the indication accuracy of the receiving beam, beam scanning rule, beam switching rule, beam dwell time, and the first beam type.

[0129] In this embodiment, the second beam information is first indicated, so that the first beam information can be dynamically indicated simply and conveniently. For example, the second beam information includes an activated transmit beam set, so that the first beam information only needs to dynamically indicate the transmit beam that sends the signal, the transmit beam that is about to send the signal, or the activated transmit beam; or, the second beam information includes an activated receive beam set, so that the first beam information only needs to dynamically indicate the receive beam that is about to receive the signal or the activated receive beam.

[0130] In some implementations, the second beam indication information may be received via higher-layer signaling, such as radio resource control (RRC) signaling, or the first beam indication information may be received via layer 1 signaling, such as downlink control information (DCI) signaling. Other signaling transmission methods are also possible, and are not limited in this embodiment of the present application.

[0131] The above beam scanning rules may be scanning rules for beams of the same type or different types, and may be scanning rules for transmitting beams.

[0132] The above beam switching rule may be a switching rule for beams of the same type or different types, and may be a switching rule for a transmitting beam or a receiving beam.

[0133] In some embodiments, the beam scanning rule includes at least one of the following:

[0134] Whether to perform beam scanning;

[0135] Scan clockwise or counterclockwise;

[0136] Uniform scanning or non-uniform scanning;

[0137] Uniform speed scanning or non-uniform speed scanning;

[0138] The order in which the beams are scanned;

[0139] Perform periodic scanning according to beam identification;

[0140] Scan back and forth according to the beam identification;

[0141] Scan according to target rules;

[0142] or,

[0143] The beam switching rule includes at least one of the following:

[0144] Whether to perform beam switching;

[0145] The order of beam switching;

[0146] Beam switching period.

[0147] The clockwise scanning or counterclockwise scanning may be performed clockwise or counterclockwise along the azimuth angle or the elevation angle dimension.

[0148] The above-mentioned non-uniform scanning may be that the beam pointing offsets before and after the beam switching are not equally spaced, and the specific scanning pattern can be directly indicated by the beam identifier, or the above-mentioned uniform scanning may be that the beam pointing offsets before and after the beam switching are equally spaced.

[0149] The non-uniform scanning may be performed with a different duration for each beam, and the uniform scanning may be performed with a same duration for each beam.

[0150] The order of the above beam scanning can be indicated by a beam identification list. For example, in FIG5(b), the order of the beam scanning is Beam#3→#5→#6.

[0151] The above-mentioned periodic scanning according to the beam identifier can be periodic scanning of multiple beams. For example, in Figure 5(b), periodic scanning is performed according to the beam identifier indication: Beam#3→#5→#6→#3→#5→#6→….

[0152] The reciprocating scanning according to the beam identification may be reciprocating scanning using multiple beams. For example, in FIG5(b), periodic scanning is performed according to the beam identification indication: Beam#3→#5→#6→#5→#3→#5→#6→….

[0153] In an embodiment of the present application, the beam identifier can also be a transmission configuration indication (TCI) state identifier, a signal identifier, an area identifier or a target identifier, etc. For example, if the beam information is indicated by multiple TCI states, the beam scanning / switching rule is to indicate the activation order of multiple TCI states associated with the signal.

[0154] The target rules described above may be other than those described above and may be protocol-specified or pre-configured. For example, beam switching may occur every X beams per scanning cycle, rather than switching to the most adjacent beam. For example, in Figure 5(a), the scanning order is: Beam #3 → #5 → #4 → #6 → #3 → #5 → ...; or, for another example, scanning from the edge of the sensing area toward the center, also using Figure 5(a) as an example, the scanning order is: Beam #3 → #6 → #4 → #5 → #3 → #6 → ....

[0155] In some implementations, if it is indicated that beam switching is not to be performed, then beam switching is not required, and there is no need to re-indicate the activated beam information. Whether to perform beam switching can be a dynamic indication.

[0156] The order of the beam switching is indicated by the beam identification list. For example, in FIG5(b), the order of the beam switching is Beam#3→#5→#6.

[0157] The beam switching period may indicate the dwell time of the beam, that is, the beam is switched after the dwell time of the beam ends. The beam switching period may be a one-time indication or a dynamic indication.

[0158] The above-mentioned beam scanning rule or beam switching rule may enable the first device to perform measurement based on a more suitable beam, thereby improving measurement performance.

[0159] In some embodiments, the above-mentioned beam scanning rules or beam switching rules can be dynamically indicated. For example, the second device dynamically indicates the beam scanning or switching method associated with the signal according to the characteristics of the perceived service, and can more flexibly perform real-time beam adjustment during the measurement process. In the scenario of tracking and perceiving the target, considering the mobility of the target, dynamic beam indication can ensure perception performance, realize on-demand configuration, and save resources.

[0160] The above-mentioned beam dwell time can be understood as the duration of each beam, which can be associated with the corresponding signal resources, for example, indicating the number of signal resource units associated with the current beam, such as the number of frames, subframes, time slots, sub-time slots, and signal symbols.

[0161] In some embodiments, the beam dwell time has at least one of the following characteristics:

[0162] The beam dwell time is greater than or equal to the coherent processing time, where the coherent processing time is the time it takes to calculate one measurement result;

[0163] The beam dwell time is associated with a signal resource interval;

[0164] The beam dwell time is greater than or equal to X signal resource units, where X is a positive integer.

[0165] Because the beam dwell time is greater than or equal to the coherent processing duration, this allows the first device to have sufficient time to calculate the measurement results, thereby improving measurement performance. For example, Tp in Figure 7 represents the signal coherent processing duration. The coherent processing time window is the time window for each calculation and output of the measurement result (for example, the time domain resource length corresponding to the range-Doppler map obtained by performing a two-dimensional Fast Fourier Transform (FFT) operation). A coherent processing duration can include multiple time slots / symbols.

[0166] The above-mentioned association between the beam dwell time and the signal resource interval may be that the beam dwell time is determined based on the signal resource interval. For example, the beam dwell time may be the signal resource interval, as shown in FIG8 , where ΔT represents the signal time domain resource interval.

[0167] Since the beam dwell time is associated with the signal resource interval, this makes it easier to match beam switching or scanning with signal resources, thereby improving measurement performance.

[0168] The above X can be a protocol agreement or a network side configuration, and the above signal resource unit can be a signal symbol, time slot, sub-time slot, frame, sub-frame and other resource units. For example: the beam dwell time is greater than or equal to X signal symbol durations (including signal symbol duration and interval duration), or the beam dwell time is greater than or equal to X other time units, such as the beam dwell time is greater than or equal to X OFDM symbol durations or X time slots, etc.

[0169] Since the beam dwell time is greater than or equal to X signal resource units, the first device may have sufficient time to calculate the measurement result, thereby improving measurement performance.

[0170] In some embodiments, for dynamically indicating the first beam information, the above-mentioned beam dwell time may indicate the duration of the currently activated beam, or the duration of the currently activated beam is from the current moment until the next first beam indication information arrives.

[0171] In some embodiments, the durations of different beams may be the same or different. For example, in FIG5(b), different targets have different velocity resolution / Doppler resolution requirements, and their corresponding signal coherence processing durations are different, and their corresponding sensing beam durations are different. The relationship between the coherence processing duration and the velocity resolution is:

[0172] For single-base sensing, For bistatic sensing, λ is the signal wavelength, β is the bistatic angle, T p is the coherent processing time, and Δv is the velocity resolution.

[0173] The first beam type may be a transmit beam type or a receive beam type, and the first beam type may include at least one of the following:

[0174] Perception reference beam, communication beam, perception beam;

[0175] The sensing reference beam or the communication beam points to a line of sight (LOS) direction of a transceiver device of the signal, and the sensing beam points to a sensing target or a sensing area.

[0176] The sensing reference beam or communication beam, referred to as the first beam type, points in the direction of the transceiver's LOS and remains relatively fixed during measurement. Movement of the transceiver may require beam switching or a change in beam direction, such as Beam #0 in Figures 5 and 6. For this first beam type, the beam switching rules for beams in the activated beam set that meet the directional requirements can be configured to not support beam scanning.

[0177] The above-mentioned perception beam can be called the second beam type, which points to the perception target or perception area. This type of beam usually needs to support flexible scanning or switching, and dynamically adjust according to the motion state of the perception target or the perception area to be covered, such as Beam#1 to #6 in Figures 5 and 6.

[0178] The above beam types can support measurement of multiple different beam types to improve measurement performance.

[0179] In some embodiments, the second beam type may also include at least one of the following:

[0180] Perception reference beam, communication beam, perception beam.

[0181] In some embodiments, the first beam indication information can be used to indicate the transmit beam associated with the signal or the receive beam used by the first device, as well as the beam scanning or switching method at one time. This can support dynamic changes in the transmit beam associated with the signal to cover multiple sensing targets or a specific sensing area, as shown in Figures 5 or 6. In addition, for the sensing system, beam scanning or dynamic switching is continuously performed according to preset rules during the measurement process. This method is used for beam indication based on the characteristics of the sensing application, eliminating the need for real-time beam switching instructions, thereby saving indication signaling overhead.

[0182] As an optional implementation manner, the first beam indication information indicates the first beam information through at least one of the following:

[0183] At least one beam identifier, a beam identifier list, quasi co-location (QCL) information, a beam set index, a bitmap indication, beam scanning range information, beam width information, beam switching offset, coverage area information, tracking target information, antenna panel information, antenna subarray information, transmit channel information, receive channel information, and signal configuration information of the signal.

[0184] The first beam indication information indicates the first beam information through the at least one item, which may refer to indicating at least one of the following through the at least one item:

[0185] Transmit beam, receive beam, beam scanning rule, beam switching rule, beam dwell time, first beam type.

[0186] The above-mentioned at least one beam identifier can indicate multiple beams at one time, or dynamically indicate a beam. For example, for the scenario where the perception beam covers a specific area as in (a) of Figure 5 or (a) of 6, it can be a starting beam identifier (Identifier, ID) and an ending beam ID that only indicate one beam scanning cycle. For example, in (a) of Figure 5 or (a) of 6, if subsequent measurements use Beam#3 to Beam#6 for perception, then {Beam#3, Beam#6} is indicated.

[0187] In some embodiments, the at least one beam identifier may indicate relative beam index information within the activated beam set based on the second beam indication information, so as to achieve dynamic beam indication.

[0188] The QCL information may indicate a QCL relationship between a signal and a resource, an antenna port, or other objects. For example, the QCL information may include at least one of the following:

[0189] QCL relationship information between the signal and the reference signal resource;

[0190] QCL relationship information between the signal and the antenna port.

[0191] The QCL relationship information between the above-mentioned signal and the reference signal resource is used to indicate the QCL relationship between the signal and the reference signal resource, so that the beam associated with the reference signal resource indicated by the QCL relationship is the beam associated with the above-mentioned signal. For example, the above-mentioned QCL relationship information indicates a list of reference signal IDs that satisfy a spatial QCL relationship (QCL-Type D) with the signal. Specifically, this can be configured through a TCI state indication, such as configuring multiple TCI states for the signal and activating them simultaneously for beam scanning, or indicating that the signal satisfies a QCL-Type D relationship with multiple reference signals through an activated TCI state.

[0192] The QCL relationship information between the above-mentioned signal and the antenna port is used to indicate the QCL relationship between the signal and the antenna port, so that the beam associated with the antenna port indicated by the QCL relationship is the beam associated with the above-mentioned signal.

[0193] The above-mentioned QCL information can implicitly indicate the first beam information, thereby saving signaling overhead.

[0194] The above-mentioned indication of the beam set index may be grouping all beams supported by the first device to obtain multiple beam sets, and assigning an index or ID to each beam set. By indicating the corresponding beam set index, a group of beams used for measurement can be indicated; wherein, all beams may be grouped according to the perception area. For example, in (a) of Figure 5, Beam#3 to Beam#6 are beam set #1, corresponding to area #1, and Beam#1 to Beam#2 are beam set #2, corresponding to area #2.

[0195] By indicating the first beam information through the above-mentioned beam set index, signaling overhead can be saved.

[0196] The above-mentioned bitmap indication can be based on the preset beam set, and the beam activated in the subsequent measurement is indicated by bitmap. For example, in (b) of Figure 5, for the preset beam set Beam#1 to #6, the subsequent measurement uses Beam#3, #5, and #6, and the bitmap information {001011} is indicated. The signaling overhead can be saved through bitmap indication.

[0197] The beam IDs and corresponding beam parameters in the above-mentioned preset beam set are known to both the first device and the second device.

[0198] The beam scanning range information may directly indicate the range of the beam scanning in subsequent measurements, such as the azimuth range or the elevation range. The beam scanning range information more simply indicates the first beam information so that the first device can perform measurements based on the corresponding beam.

[0199] The above-mentioned beam width information can directly indicate the beam width during subsequent measurements, such as the horizontal beam width or the vertical beam width, and the first beam information can be more simply indicated through the beam scanning range information so that the first device can perform measurements based on the corresponding beam.

[0200] The above-mentioned beam switching offset can directly indicate the angular offset of the adjacent beam pointing in subsequent measurements. In this way, the beam switching offset can more accurately indicate the adjacent beam associated with the signal, so that the first device can perform measurements based on the corresponding beam.

[0201] In some embodiments, the above-mentioned beam scanning range information, beam width information or beam switching offset can be based on the existing preset beam set information, and the beam scanning range information, beam width information or beam switching offset can indicate the beam activated for subsequent measurement; or, the beam scanning range information, beam width information or beam switching offset can be directly used to determine the activated beam based on the beam scanning angle range, beam width and angle offset.

[0202] In some implementations, the beam switching offset indicates relative offset information based on the last activated beam. This can be an offset in the beam pointing angle or a beam index. For example, in FIG5(a), if the last activated beam was Beam#4 and the currently activated beam is Beam#3, the beam index offset can be -1. Alternatively, if the last activated beam was Beam#4 and the currently activated beam is Beam#5, the beam index offset can be +1. In this way, the beam switching offset can dynamically indicate the transmit or receive beam of a signal.

[0203] The above-mentioned coverage area information may be a mapping relationship between the coverage area and the beam, so that the corresponding beam is indicated by the coverage area information. For example: the area supported by the first device is divided into different sub-areas, each sub-area has a specific identification ID, associated with a specific beam, and the beam information used is indicated by indicating the area ID. For example, with the first device as the origin, its coverage range is rasterized and divided into multiple perception areas, each area is associated with an area ID, as shown in Figure 9, the dotted line represents the coverage area of ​​the first device, and each square represents a divided perception area.

[0204] Indicating the first beam information through the above coverage area information can improve the accuracy of beam indication.

[0205] The tracking target information may indicate the target to be tracked. A pre-established mapping relationship between targets and beams allows different beams to track different targets. For example, based on prior target information (which may be obtained from historical measurements), specific identification IDs may be assigned to different targets, and the target IDs may be used to indicate the beam information to be used.

[0206] Since the first beam information is implicitly indicated by the tracking target information, signaling overhead can be reduced.

[0207] The antenna panel information, antenna subarray information, transmit channel information, or receive channel information mentioned above refers to a mapping relationship between the antenna panel information, antenna subarray information, transmit channel information, or receive channel information and the beam information. Thus, the corresponding beam information is indicated by the antenna panel information, antenna subarray information, transmit channel information, or receive channel information. This implicit indication of beam information by the antenna panel information, antenna subarray information, transmit channel information, or receive channel information can reduce signaling overhead.

[0208] The signal configuration information of the above-mentioned signal may be a beam associated with at least one signal resource, so that corresponding beam information can be indicated for different signals. For example, different signal resources are associated with different beams in the signal configuration information, and the beam scanning process is realized by configuring multiple signal resources, wherein the relationship between the signal and the transmitting (or receiving) beam may be as shown in Figure 10 or Figure 11.

[0209] Since the first beam information is indicated by the signal configuration information of the signal, signaling overhead can be saved because there is no need to additionally configure other information to indicate the first beam information.

[0210] In some embodiments, the signal configuration information of the above-mentioned signal may explicitly or implicitly indicate the above-mentioned first beam information, for example: the above-mentioned signal configuration information includes the first beam information.

[0211] In some embodiments, the first beam indication information includes signal configuration information of N signals, where N is a positive integer;

[0212] The N signals correspond to transmitting beams in N directions, or the N signals correspond to receiving beams in M ​​directions.

[0213] The N signals corresponding to the transmission beams in N directions may be multiple signals corresponding to transmission beams in multiple different directions, that is, the multiple signals are sent using different spatial filters and are associated with specific receiving beams.

[0214] The N signals corresponding to the receiving beams in M ​​directions may mean that some of the signals correspond to receiving beams in the same direction, or some of the signals correspond to receiving beams in different directions.

[0215] Since the N signals correspond to transmitting beams in N directions or the N signals correspond to receiving beams in M ​​directions, the beams associated with the N signals can be flexibly configured, thereby improving measurement flexibility.

[0216] In some embodiments, the N directions are associated with a perception angle range, or the M directions are associated with a perception angle range.

[0217] The association of the above-mentioned N directions with the perception angle range can be understood as the above-mentioned N directions being determined based on the perception angle range, thereby making the transmission beams of the N signals more suitable for measurement, thereby improving measurement performance.

[0218] The association of the above-mentioned M directions with the perception angle range can be understood as the above-mentioned M directions being determined based on the perception angle range, thereby making the receiving beams of the N signals more suitable for measurement, thereby improving measurement performance.

[0219] In some embodiments, when there is a first signal sent over multiple time units among the N signals, the multiple time units corresponding to the first signal satisfy at least one of the following:

[0220] The duration of the multiple time units is greater than or equal to the coherent processing duration, or the duration of the multiple time units is greater than or equal to the coherent processing duration, where the coherent processing duration is the duration for calculating one measurement result;

[0221] The time interval between two adjacent time units in the multiple time units meets the Doppler unambiguous measurement requirement or the speed unambiguous measurement requirement.

[0222] The first signal sent over multiple time units may be understood as the first signal occupying multiple time units, such as multiple symbols, sub-slots, time slots, subframes, and the like.

[0223] In this implementation, since the duration occupied by the multiple time units is greater than or equal to the coherent processing duration, the first device has enough time to calculate the measurement result.

[0224] In some implementations, the duration of each signal may be greater than or equal to the coherent processing duration.

[0225] Since the time interval between two adjacent time units in the multiple time units meets the Doppler unambiguous measurement requirement or the velocity unambiguous measurement requirement, the first device can perform measurement based on the first signal, making the measurement result more reliable.

[0226] The above-mentioned Doppler unambiguous measurement requirement or velocity unambiguous measurement requirement may be a protocol requirement or a network-side configuration, for example:

[0227] For single-base sensing:

[0228] If the velocity direction is considered, the time interval satisfies ΔT≤1 / (2|f dmax |) or If the time interval in the direction of velocity is not considered and satisfies ΔT≤1 / f dmax or where f dmaxis the maximum unambiguous Doppler, v max is the maximum unambiguous velocity, f c is the carrier frequency and c is the speed of light.

[0229] For bistatic perception:

[0230] If the velocity direction is considered, the time interval satisfies ΔT≤1 / (2|f dmax |) or If the time interval in the direction of velocity is not considered and satisfies ΔT≤1 / f dmax or β is the bistatic angle.

[0231] In some embodiments, the frequency domain bandwidth corresponding to each of the N signals satisfies B≥c / (2ΔR), where B is the frequency domain bandwidth, c is the speed of light, and ΔR is the range resolution;

[0232] or,

[0233] When there is a second signal sent on multiple frequency domain units among the N signals, the frequency domain interval between two adjacent frequency domain units of the multiple frequency domain units corresponding to the second signal meets the requirement of unambiguous measurement of delay or unambiguous measurement of distance.

[0234] The second signal sent on multiple frequency domain units can be understood as the second signal occupying multiple frequency domain units, such as occupying multiple resource elements (REs), resource blocks, physical resource blocks, etc.

[0235] In this implementation, the frequency domain bandwidth corresponding to each signal satisfies B≥c / (2ΔR), so that the first device can receive the signal more reliably, thereby improving measurement performance.

[0236] The above-mentioned unambiguous measurement requirements for delay or distance can be agreed upon by the protocol or configured by the network side equipment. max Or Δf≤c / (2R max ), where τ max is the maximum unambiguous delay, v max is the maximum unambiguous distance.

[0237] Since the frequency domain interval between the two frequency domain units meets the requirement of unambiguous measurement of delay or unambiguous measurement of distance, the first device can perform measurement based on the first signal, making the measurement result more reliable.

[0238] In some implementations, the signal configuration information may also include at least one of the following:

[0239] Signal resource identification, signal usage, waveform, subcarrier spacing, guard interval, frequency domain starting position, frequency domain resource length, frequency domain resource interval, time domain starting position, time domain resource length, time domain resource interval, time domain burst information, time domain resource characteristics, signal power, sequence information, signal direction, Quasi Co-Location (QCL) relationship, and cyclic prefix information.

[0240] The above signal resource identifier is used to distinguish different signal resource configurations;

[0241] The signal usage indicates whether the target signal is used for communication (e.g., channel measurement, channel estimation, synchronization, carrying data information, etc.), a signal used for sensing, or a signal used for both communication and sensing. Specifically, it may also indicate which sensing service the signal is used for, or which type of sensing service the signal is used for.

[0242] The sensing service may include at least one of the following:

[0243] Detect target presence, positioning, speed detection, distance detection, angle detection, acceleration detection, material analysis, component analysis, shape detection, classification, radar cross section area (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, respiratory 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.

[0244] The waveform may be OFDM, single-carrier frequency-division multiple access (SC-FDMA), orthogonal time-frequency space (OTFS), frequency modulated continuous wave (FMCW), or a pulse signal;

[0245] The above subcarrier spacing may be the subcarrier spacing of an OFDM system, for example, 30 kHz.

[0246] The guard interval can be the time interval from the moment the signal ends to the moment the latest echo signal of the signal is received. This parameter is proportional to the maximum sensing distance. For example, it can be calculated by c / (2R max ) is calculated, R max is the maximum sensing distance (belonging to the sensing demand information), such as for the self-transmitted and self-received signal, R max Represents the maximum distance from the signal receiving and transmitting point to the signal reflection point. In some cases, the OFDM signal cyclic prefix (CP) can serve as the minimum guard interval, and c is the speed of light.

[0304] 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.

[0305] 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.

[0311] The total received power is the total received power of the first device on the target resource.

[0312] 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.

[0313] 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.

[0314] 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.

[0315] In some implementations, the perception indicator related to received power and also related to interference or noise power may further include at least one of the following:

[0316] Indicators related to the perceived signal-to-noise and interference ratio (SINR), indicators related to the perceived signal-to-noise ratio (SNR), indicators related to the perceived signal-interference ratio (SIR), and indicators related to the perceived reference signal received quality (RSRQ).

[0317] In some embodiments, the path associated with the sensory target satisfies at least one of the following:

[0318] The parameter meets the first preset threshold, or the parameter is within the first preset range;

[0319] The parameters meet the preset modulation rules;

[0320] 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;

[0321] 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.

[0322] The above parameters may include at least one of the following:

[0323] Amplitude, power, intensity, energy, phase, Doppler, delay, angle;

[0324] The above parameter difference may include at least one of the following:

[0326] 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.

[0327] 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).

[0328] The first arrival path can be a line-of-sight (LOS) path, specifically the path that first reaches the receiver in the sensed signal. The reference path can be a path reflected by a known target, such as a reconfigurable intelligence surface (RIS), backscatter, or other known passive targets.

[0329] 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.

[0330] 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.

[0331] 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 FIG12 , 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.

[0332] 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.

[0333] The calculation method 1 of the first indicator is as follows:

[0334] The first device (e.g., a terminal) performs channel estimation based on the transmitted perception signal X(k) and the received signal Y(k) corresponding to the perception 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 a 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.

[0335] The first dimension includes one of the following:

[0336] Delay dimension;

[0337] Doplevi;

[0338] Azimuth dimension;

[0339] Pitch angle dimension;

[0340] A dimension that combines at least two of the following: delay, Doppler, azimuth, and elevation dimensions. For example, delay-Doppler, delay-Doppler-angle, etc.

[0341] 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.

[0342] Method for determining the path associated with the sensing target (referred to as the sensing path for short) in the channel response obtained by measuring the sensing signal:

[0343] 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 12, 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.

[0344] A path that satisfies a first condition is selected from the path set or from all paths of the perception signal as the path associated with the perception target. The first condition includes at least one of the following:

[0345] 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;

[0346] The Doppler of the path exceeds the preset threshold or is within the preset range;

[0347] The path delay exceeds the preset threshold or is within the preset range;

[0348] The angle of the path exceeds the preset threshold or is within the preset range;

[0349] 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.);

[0350] 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;

[0351] 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;

[0352] 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;

[0353] 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.

[0354] 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;

[0355] 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.

[0356] The priori perception information or perception requirements include the following information:

[0357] Perception services or perception service types, such as detecting whether a target exists, positioning, speed detection, distance detection, angle detection, acceleration detection, material analysis, component analysis, shape detection, classification, radar cross section area (Radar Cross Section Area), etc. 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;

[0358] 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;

[0359] 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.

[0360] 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.

[0361] For example, in FIG12 , 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.

[0362] FIG12 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.

[0363] 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.

[0364] The calculation method 2 of the first indicator can be as follows:

[0365] 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.

[0366] The calculation method 1 of the received power of the sensing signal can be as follows:

[0367] The received power of the perceived signal may be obtained by the receiving device, after transforming the channel response (Channel Response) H(k) into a first dimension, determining a path set in the first dimension, and then calculating the power sum of all paths in the path set.

[0368] Method 2 for calculating the received power of the sensing signal may be as follows:

[0369] The received power of the perception 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.

[0370] The total received power is calculated as follows:

[0371] Total received power

[0372] Wherein, Y(k) is the received signal corresponding to the perception signal, k=0, 1, 2, ..., K-1 represents the resource unit index, and K is the number of resource units.

[0373] The second indicator can be calculated as follows:

[0374] The channel response H(k) is processed by the first filter to obtain H filter1 (k), then according to H filter1 (k) and the perception signal X(k) are used to calculate the received signal Y after the first filtering process filter1 (k), that is, Y filter1 (k)=H filter1 (k)X(k). Then the received signal Y(k) is subtracted from the received signal Y after the first filtering process. filter1 (k) Thus we get the interference and noise signal Y σ1 (k), that is, Y σ1 (k) = Y(k) - Y filter1 (k), and then calculate the second indicator:

[0375] 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 FIG12 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.

[0376] The calculation method 1 of the third indicator can be as follows:

[0377] The channel response H(k) is processed by the second filter to obtain H filter2 (k), then according to H filter2 (k) and the perception signal X(k) are used to calculate the received signal Y after the second filtering process filter2 (k), that is, Y filter2 (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:

[0378] 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 FIG12 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.

[0379] The calculation method 2 of the third indicator can be as follows:

[0380] 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.

[0381] 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:

[0382] Method 1: Calculate the perception-related indicators (also called target indicators) of each perception target separately. For example, in Figure 12, the path associated with each perception target is determined separately, and then the perception-related indicators corresponding to each perception target are calculated separately; when calculating the second indicator corresponding to a certain perception target (such as perception target A), there are two methods: namely: 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 = RSRP of perception signal - the first indicator of perception target A; or, the fourth indicator of perception target A = RSRP of perception signal - the first indicator of perception target A - the first indicator of perception target B; (assuming there are two perception targets: A and B)

[0383] Method 2: Calculate a perception-related index for multiple perception targets. For example, in Figure 12, 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.

[0480] It should be noted that this embodiment is an implementation of the second device corresponding to the embodiment shown in Figure 4. Its specific implementation can refer to the relevant description of the embodiment shown in Figure 4. In order to avoid repeated description, this embodiment will not be repeated.

[0481] The following uses perception measurement as an example to illustrate the method provided in the embodiments of the present application through multiple embodiments:

[0482] Example 1:

[0483] This embodiment provides a one-time configuration of the transmit beam associated with the configured sensing signal or the receive beam used by the receiving device, as well as a beam scanning or switching method. Specifically, the transmit beam associated with the sensing signal changes dynamically to cover multiple sensing targets or a specific sensing area, as shown in Figures 5 or 6. For the sensing system, beam scanning or dynamic switching is continuously performed according to preset rules during the measurement process. This method, used for beam indication based on the characteristics of the sensing application, eliminates the need for real-time beam switching instructions, thus reducing indication signaling overhead.

[0484] The second device sends first beam indication information to the first device, where the first beam indication information is used to indicate first beam information used in the first device's perception measurement. The first beam information includes at least one of transmit beam information and receive beam information. Both may be indicated separately, or the first device may determine one of the transmit beam information and receive beam information based on the other, i.e., determine transmit and receive beam pair information. For example, in FIG5(a), through beam training or other historical measurement information, the first device determines that the optimal receive beam corresponding to transmit beams Beam#3 and #4 is Beam#2, and the optimal receive beam corresponding to transmit beams Beam#5 and #6 is Beam#3.

[0485] The first beam information indicated by the first sensing beam indication information includes at least one of the following:

[0486] Activated beam set, beam scanning rule, beam switching rule, beam dwell time, first beam type.

[0487] The activated beam set refers to the information of the beams that may be used in the sensing measurement, and can be indicated in at least one of the following ways:

[0488] Indicates at least one beam ID, or a list of beam IDs. For example, it may indicate the QCL relationship between the perception signal and at least one reference signal resource, or antenna port, such as indicating a list of reference signal IDs that satisfy the spatial QCL relationship (QCL-TypeD) with the perception signal. Specifically, it may be configured through a TCI state indication, such as configuring multiple TCI states for the perception signal and activating them simultaneously to indicate beam scanning, or indicating that the perception signal satisfies the QCL-TypeD relationship with multiple reference signals through an activated TCI state; or, for a scenario where the perception beam covers a specific area as in FIG5(a) or FIG6(a), it may be an indication of the starting beam ID and the ending beam ID of only one beam scanning cycle, such as in FIG5(a) or FIG6(a), if the subsequent perception measurement in FIG5(a) or FIG6(a) uses Beam#3 to Beam#6 for perception, then {Beam#3, Beam#6} is indicated;

[0489] Indicates a beam set index, i.e., groups all beams supported by the device to obtain multiple beam sets, assigns an index or ID to each beam set, and indicates a group of beams used for perception measurement by indicating the corresponding beam set index. Grouping all beams may be based on perception areas. For example, in Figure 5(a), Beams #3 to #6 are Beam Set #1, corresponding to Area #1, and Beams #1 to #2 are Beam Set #2, corresponding to Area #2.

[0490] Based on the preset beam set, the beams activated in subsequent sensing measurements are indicated by a bitmap. For example, in Figure 5(b), for the preset beam set Beam#1 to #6, subsequent sensing measurements use Beam#3, #5, and #6, and the bitmap information {001011} is indicated.

[0491] Directly indicates the range (azimuth range, elevation range) of the beam scan during subsequent perception measurement, and / or the beam width (horizontal beam width, vertical beam width), and / or the offset of the beam switching (the angular offset of the adjacent beam pointing). For example, based on the existing preset beam set information, the beam activated for subsequent perception measurement can be obtained by the beam scan angle range, or the activated beam information can be directly determined based on the beam scan angle range, beam width, and angle offset. The beam ID and corresponding beam parameters in the preset beam set are known to both the sender and the receiver.

[0492] Indicates the area information that needs to be covered. The area supported by the sensing device is divided into different sub-areas. Each sub-area has a specific identification ID and is associated with a specific beam. The beam information used is indicated by indicating the area ID. For example, with the base station as the origin, its coverage area is rasterized and divided into multiple sensing areas. Each area is associated with an area ID. As shown in Figure 9, the dotted line represents the base station coverage area, and each square represents the divided sensing area.

[0493] Indicate the target information to be tracked, for example, assign specific identification IDs to different targets based on target prior information (which can be obtained from historical measurements), and indicate the beam information to be used by indicating the target ID;

[0494] Indicating panel information or sub-array information, wherein the panel or sub-array is associated with different beams, or indicating transmit channel or receive channel information;

[0495] The beam scanning / switching rules may be preset (agreed upon by protocol, or configured in advance) different types of beam scanning / switching rules, indicating which rule to use during measurement.

[0496] The above-mentioned preset rules may include at least one of the following:

[0497] Whether to perform beam scanning or switching;

[0498] Scan clockwise (along the azimuth or elevation dimension);

[0499] Scan counterclockwise (along the azimuth or elevation dimension);

[0500] Uniform scanning or non-uniform scanning. Non-uniform scanning means that the beam pointing offset before and after beam switching is not evenly spaced. The specific scanning pattern can be directly indicated by the beam ID;

[0501] Uniform scanning or non-uniform scanning, non-uniform scanning means that the duration of each beam is different;

[0502] The order of beam scanning or switching can be indicated by a beam ID list. For example, in FIG5(b), the order of beam switching is Beam#3→#5→#6.

[0503] Perform periodic scanning according to the beam ID indication. For example, in FIG5(b), perform periodic scanning according to the beam ID indication: Beam#3→#5→#6→#3→#5→#6→…;

[0504] Perform reciprocating scanning according to the beam ID indication. For example, in FIG5(b), perform periodic scanning according to the beam ID indication: Beam#3→#5→#6→#5→#3→#5→#6→…;

[0505] It should be noted that the beam ID also includes the TCI state ID, signal ID, area ID or target ID described above. For example, if the beam information is indicated by multiple TCI states, the beam scanning / switching rules indicate the activation order of multiple TCI states associated with the perception signal.

[0506] Alternatively, beam scanning may be performed according to other preset rules. For example, beam switching may be performed every X beams in each scanning cycle, rather than switching to the most adjacent beam. For example, in FIG5 (a), the scanning order is: Beam#3→#5→#4→#6→#3→#5→…; for another example, scanning from the edge to the center of the sensing area, also taking FIG5 (a) as an example, the scanning order is: Beam#3→#6→#4→#5→#3→#6→….

[0507] The beam dwell time or switching period, that is, the duration of each beam, can be associated with the corresponding signal resources, for example, indicating the number of signal resource units associated with the current beam (such as the number of perception signal symbols).

[0508] Among them, the beam dwell time can be no less than one coherent processing time. For example, Tp in Figure 7 represents the coherent processing time of the perception signal. The coherent processing time window is the time window for each calculation and output of the perception measurement result (for example, performing a two-dimensional FFT operation to obtain the time domain resource length corresponding to the range-Doppler map). One coherent processing time can include multiple time slots / symbols.

[0509] Alternatively, the beam dwell time may be a sensing signal resource interval. For example, ΔT in FIG8 represents a sensing signal time domain resource interval.

[0510] Alternatively, the beam dwell time may be not less than X sensing signal resource unit durations, for example, not less than X sensing signal symbol durations (including sensing signal symbol durations and interval durations), or not less than X other time units, for example, not less than X OFDM symbol durations or X time slots.

[0511] The durations of different beams can be the same or different. For example, in Figure 5(b), different targets have different velocity resolution / Doppler resolution requirements, and their corresponding signal coherence processing durations are different, and their corresponding perception beam durations are different. The relationship between the coherence processing duration and velocity resolution is:

[0512] For single-base sensing, For bistatic sensing, λ is the signal wavelength, β is the bistatic angle, T p is the coherent processing time, and Δv is the velocity resolution.

[0513] The first beam type may include:

[0514] The perception reference beam or communication beam points to the LOS direction of the transceiver device and is relatively fixed during the perception measurement process. When the transceiver device moves, beam switching or changing the beam direction may be involved, such as Beam#0 in Figures 5 and 6. For this beam type, the beam switching rules corresponding to the beams that meet the direction requirements in the activated beam set can be configured to not support beam scanning.

[0515] The perception beam points to the perception target or perception area. This type of beam usually needs to support flexible scanning or switching and dynamically adjust according to the motion state of the perception target or the perception area to be covered, such as Beam#1 to #6 in Figures 5 and 6.

[0516] Before the second device sends the beam indication information to the first device, the second device further includes obtaining capability information, sensing requirement information, or sensing target prior information of the first device. The second device determines the first beam indication information based on the capability information, sensing requirement information, or sensing target prior information of the first device.

[0517] The first device capability information includes at least one of the following:

[0518] The maximum number of beams supported or the supported beam set information can also be the maximum perception area information that can be covered, the maximum perception angle range information, the maximum number of perception targets, etc.

[0519] Supports the number of beams or beam set information that can be activated simultaneously;

[0520] Supported beamwidth information;

[0521] Antenna information, including antenna panel or array information;

[0522] Beam scanning or switching related capability information, including at least one of whether beam scanning is supported, supported scanning rules, beam switching step size, and beam scanning / switching speed;

[0523] The prior information of the perceived target (which may be obtained through historical measurements) includes at least one of the following:

[0524] Number of perceived targets;

[0525] Perceive target location information;

[0526] Perceive the target's position relative to the transmitting or receiving device;

[0527] Perceive target motion speed information, including speed or direction;

[0528] The first device receives the sensing signal and performs measurement based on the first beam indication information to obtain a measurement result; or the first device sends the sensing signal, receives the sensing signal echo, and performs measurement based on the first beam indication information to obtain a measurement result. The measurement result includes at least one of the following:

[0529] The measurement result corresponding to the perceived measurement quantity, i.e., the value of the measurement quantity;

[0530] performance indicators associated with perception;

[0531] Recommended beam information, including at least one of the following:

[0532] Recommended activated beam set information;

[0533] Recommended beam scanning rules;

[0534] Recommended beam dwell time or beam scanning / switching speed;

[0535] Recommended beam switching step size;

[0536] Recommended beamwidth.

[0537] The first device sends the measurement result to the second device or the third device.

[0538] It should be noted that this embodiment can also be extended to support multiple simultaneous beam transmission or reception, thereby improving sensing measurement efficiency. For example, by configuring multi-port sensing signals or multiple sensing signal resources, multiple beams can be used to transmit signals simultaneously at each moment. The signal corresponding to each port or the beam indication method for each signal resource is the same as the solution provided in this embodiment.

[0539] Example 2:

[0540] In this embodiment, a beam scanning or switching method associated with a perception signal is dynamically indicated based on the characteristics of the perception service. Compared with Example 1, real-time beam adjustment can be performed more flexibly during the measurement process. For the scenario of Figure 5 (b) or Figure 6 (b), the target is tracked and perceived based on the target prior information. Taking into account the mobility of the target, dynamic beam indication can ensure perception performance, realize on-demand configuration, and save resources.

[0541] The second device optionally sends second beam indication information to the first device, where the second beam indication information is used to indicate all beam information used by the first device for sensing measurement. The second beam indication information includes at least one of the following:

[0542] Activated beam set information, when the subsequent dynamic instruction beam switching is performed, the activated beam is selected according to the activated beam set information

[0543] Second beam type.

[0544] The second device sends first beam indication information to the first device, where the first beam indication information is used to dynamically indicate first beam information used by the first device in subsequent measurements. The first beam indication information includes at least one of the following:

[0545] The activated beam information, i.e., the beam currently used for measurement, is specifically defined in the activated beam set information, except that the activated beam information is only for a single beam. The indicated beam ID information may also indicate the relative beam index information within the activated beam set based on the first beam indication information.

[0546] Alternatively, based on the last activated beam information, relative offset information is indicated, which can be an offset of the beam pointing angle or an offset of the beam index. For example, in FIG5(a), if the last activated beam was Beam#4 and the currently activated beam is Beam#3, the beam index offset can be -1. Alternatively, if the last activated beam was Beam#4 and the currently activated beam is Beam#5, the beam index offset can be +1.

[0547] Indication of whether to perform beam switching. If beam switching is not required, there is no need to re-indicate the activated beam information;

[0548] The beam dwell time or switching period indicates the duration of the currently activated beam. For the specific definition, please refer to Example 1. Alternatively, by default, the duration of the currently activated beam is from the current moment until the next second beam indication information arrives.

[0549] In one implementation, the second beam indication information is sent via high-layer signaling (RRC signaling) and the first beam indication information is sent via layer 1 signaling (eg, DCI signaling). Other signaling transmission methods may also be used, and this embodiment does not limit this.

[0550] Before the second device sends the first / second beam indication information to the first device, the second device further includes obtaining capability information, perception requirement information, or perception target prior information of the first device. The second device determines the first / second beam indication information based on the capability information, perception requirement information, or perception target prior information of the first device.

[0551] The first device receives the sensing signal and performs measurement based on the first beam indication information to obtain a measurement result. Alternatively, the first device sends the sensing signal, receives an echo of the sensing signal, and performs measurement based on the first beam indication information to obtain a measurement result, where the measurement result includes at least one of the following:

[0552] The measurement result corresponding to the perceived measurement quantity, i.e., the value of the measurement quantity;

[0553] performance indicators associated with perception;

[0554] Recommended beam information, including at least one of the following:

[0555] Recommended activation beam information;

[0556] Recommended beam dwell time or beam scanning / switching speed

[0557] Recommended beam switching step size;

[0558] Recommended beamwidth;

[0559] The first device sends the measurement result to the second device or the third device.

[0560] Similar to Example 1, this embodiment can also be expanded to support multiple simultaneous beam transmission or reception, thereby improving sensing measurement efficiency. For example, by configuring multi-port sensing signals or multiple sensing signal resources, multiple beams can be used to transmit signals simultaneously at each moment. The signal corresponding to each port or the beam indication method for each signal resource is the same as the solution provided in this embodiment.

[0561] Example 3:

[0562] In this embodiment, different sensing signals may be configured for indication. Different sensing signal resources are associated with different beams in the sensing signal configuration information. The beam scanning process is implemented by configuring multiple sensing signal resources, as shown in FIG11 and FIG12 .

[0563] The second device sends multiple perception signal configuration information to the first device, where the perception signal configuration information includes beam information associated with the perception signal. The multiple perception signals correspond to beams in multiple directions, that is, the multiple perception signals are sent using different spatial filters and are associated with specific receiving beams. The perception signal is a perception signal, and the perception signal configuration information is associated with a perception requirement, including:

[0564] N sensing signals correspond to N transmit beams in different directions (and / or, M receive beams in different directions). The N beam directions (and / or, M beam directions) are associated with the field of view (FoV). FoV can be related to the device capability, the area to be sensed, or the distribution of the sensing target.

[0565] The time domain resource of each sensing signal includes one or more (>=2) time units (for example, multiple OFDM symbols, where the multiple time units can be continuous or non-continuous). When multiple time units are included:

[0566] The time domain duration corresponding to each perception signal or the duration occupied by multiple time units is greater than or equal to the coherent processing duration, and the definition of the coherent processing duration is the same as that of Example 1

[0567] Among multiple time units, the time interval between two adjacent time units, where the time domain interval △T (Note: △T here refers to the time domain resource interval of the same signal (sent using the same beam) in Figure 11 or Figure 12) meets the Doppler / speed unambiguous measurement requirements, and the frequency domain interval △f meets the delay / distance unambiguous measurement requirements.

[0568] For example, for single-base sensing:

[0569] If the velocity direction is considered, the time interval satisfies ΔT≤1 / (2|f dmax |) or If the time interval in the direction of velocity is not considered and satisfies ΔT≤1 / f dmax or 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.
