[0051] In some embodiments, network-side devices and terminals, in addition to communication capabilities, may possess sensing capabilities. Sensing capabilities refer to the ability of one or more devices to sense information such as the location, distance, and speed of a target object through the transmission and reception of wireless signals, or to detect, track, identify, and image target objects, events, or environments. Some sensing 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 merely illustrative examples, and the categories of perception measurements are not limited in this application embodiment.

[0054] Furthermore, the embodiments of this application can be applied to integrated communication and sensing scenarios. Integrated communication and sensing refers to the integrated design of communication and sensing functions in the same system through spectrum sharing and hardware sharing. While transmitting information, the system can sense information such as location, distance, and speed, and detect, track, and identify target devices or events. The communication system and the sensing system complement each other, thereby improving overall performance and bringing a better service experience.

[0055] For example, the integration of communication and radar is a typical application of communication and sensing integration (communication and sensing fusion). The integration of communication and radar systems can bring many advantages, such as cost savings, size reduction, power consumption reduction, improved spectrum efficiency, and reduced mutual interference, thereby improving the overall system performance.

[0056] In this embodiment, depending on the different transmitting and receiving nodes of the sensing signal, there may be, but is not limited to, the six sensing links shown in Figure 2. It should be noted that each sensing link in Figure 2 is illustrated with one transmitting node and one receiving node. In actual systems, different sensing links can be selected according to different sensing requirements. Each sensing link may have one or more transmitting and receiving nodes, and the actual sensing system may include multiple different sensing links. Furthermore, the sensing targets in Figure 2 are people and vehicles as examples, and it is assumed that neither people nor vehicles carry or have installed signal transceiver equipment. The sensing targets in actual scenarios will be much more diverse.

[0057] Sensing Link 1: Base station self-transmitting and self-receiving sensing. In this method, the base station sends sensing signals and obtains the sensing results by receiving the echoes of these signals;

[0058] Sensing Link 2: Inter-base station air interface sensing. In this mode, base station 2 receives sensing signals sent by base station 1 and obtains the sensing results.

[0059] Sensing Link 3: Uplink air interface sensing. In this mode, the base station receives sensing signals sent by the terminal and obtains the sensing results.

[0060] Sensing Link 4: Downlink Air Interface Sensing. In this mode, the terminal receives sensing signals sent by the base station and obtains the sensing results.

[0061] Sensing Link 5: Terminal Self-Sending and Receiving Sensing. In this mode, the terminal sends a sensing signal and obtains the sensing result by receiving the echo of the sensing signal.

[0062] Sensing Link 6: Sidelink sensing between terminals. For example, terminal 2 receives a sensing signal sent by terminal 1 and obtains a sensing result, or terminal 1 receives a sensing signal sent by terminal 2 and obtains a sensing result.

[0063] In some embodiments, signaling transmission between radio access network devices and terminals, and between different terminals, may be via Radio Resource Control (RRC) signaling, Medium Access Control Control Element (MAC CE), Layer 1 signaling, or other newly defined sensing signaling; signaling transmission between sensing network functions and terminals may be via Non-Access-Stratum (NAS) signaling (forwarded via AMF), or via RRC signaling, MAC CE, Layer 1 signaling, or other newly defined sensing signaling; interaction between sensing network functions and base stations may be via AMF forwarding to the radio access network through the N2 interface; or the core network sensing network function may send the signal to the UPF, which in turn sends it to the radio access network through the N3 interface; or the signal may be sent to the radio access network (e.g., a base station) through a newly defined interface; signaling transmission between radio access network devices may be via the Xn interface.

[0064] In some embodiments, the sensing network function can also be called a sensing network element or sensing management function (Sensing MF). It can be located on the RAN side or the core network side. It refers to a network node in the core network or RAN that is responsible for at least one of the following functions: sensing request processing, sensing resource scheduling, sensing information interaction, and sensing data processing. It can be an upgrade based on the AMF or LMF in the mobile communication network, or it can be other network nodes or newly defined network nodes. Specifically, the functional characteristics of the sensing network function / sensing network element may include at least one of the following:

[0065] The system interacts with wireless signal transmitting devices or wireless signal measuring devices (including target terminals or base stations serving the target terminals or associated with the target area) to exchange target information. The target information includes sensing processing requests, sensing capabilities, sensing auxiliary data, sensing measurement types, sensing resource configuration information, etc., in order to obtain the value of the target sensing result or sensing measurement (uplink measurement or downlink measurement) sent by the wireless signal measuring device. The wireless signal can also be referred to as the sensing signal.

[0066] The sensing method used is determined based on factors such as the type of sensing service, the information of sensing service consumers, the required Quality of Service (QoS) requirements, the sensing capabilities of the wireless signal transmitting equipment, and the sensing capabilities of the wireless signal measuring equipment. This sensing method may include: wireless access network device A transmitting and wireless access network device B receiving, or wireless access network device transmitting and terminal receiving, or wireless access network device A transmitting and receiving, or terminal transmitting and receiving, or terminal A transmitting and terminal B receiving, etc.

[0067] The sensing equipment serving the sensing service is determined based on factors such as the type of sensing service, information about the sensing service consumers, the required sensing QoS requirements, the sensing capabilities of the wireless signal transmitting equipment, and the sensing capabilities of the wireless signal measuring equipment. The sensing equipment includes either wireless signal transmitting equipment or wireless signal measuring equipment.

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

[0069] The system processes or calculates the values ​​of sensed measurements to obtain sensing results. It can also verify sensing results and estimate sensing accuracy.

[0070] In some embodiments, radars can be classified into monostatic radars and bistatic / multistatic radars based on whether the transmitter and receiver are separate. Bistatic radars generally require a long distance between the transmitting and receiving antennas, comparable to the radar's effective range. Among them, external radiation source radar is a special case of bistatic radar. It utilizes relevant electromagnetic wave detection theories and signal processing techniques to acquire non-cooperative electromagnetic signals emitted by a third party (such as a communication base station) to achieve target detection, location, tracking, and identification. It is also called passive radar, bistatic / multistatic passive radar, passive radar, non-cooperative illumination source radar, or non-cooperative passive detection system.

[0071] The calculation of bistatic radar sensing results generally requires the use of a reference channel (direct path) signal and a monitoring channel (reflection path) signal. A typical bistatic radar architecture is shown in Figure 3. R T R is the distance from the signal transmitter (Tx) to the target.R The distance from the signal receiver (Tx) to the target is given by θ, where L is the baseline distance and θ is the distance from the receiver to the target. T Let θ be the angle of the target relative to the signal transmitter. R (θ R1 θ R2 ) represents the angle of the target relative to the signal receiver, and β represents the bistatic angle.

[0072] In some embodiments, for range, Doppler, or velocity measurements commonly used in sensing measurements, measurement ambiguity can occur when signal resource configuration does not meet requirements. For example, for monostatic radar sensing, the relationship between the maximum unambiguous range, Doppler, or velocity and signal resource configuration is as follows:

[0073] If the velocity 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 velocity direction is not considered, ΔT≤1 / f dmax Or ΔT≤c / (2f) c v max ), where f dmax For the maximum unambiguous Doppler, v max For the maximum unambiguous velocity, f c denoted as carrier frequency, and c as the speed of light.

[0074] Frequency domain resource spacing satisfies Δf≤1 / τ max Or Δf≤c / (2R) max ), where τ max For the maximum unambiguous delay, R max The maximum unambiguous distance.

[0075] In other words, 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, velocity / Doppler ambiguity will be transmitted.

[0076] The following description, in conjunction with the accompanying drawings, details a measurement method, measurement indication method, apparatus, and device provided in this application through some embodiments and application scenarios.

[0077] Please refer to Figure 4, which is a flowchart of a measurement method provided in an embodiment of this application. As shown in Figure 4, it includes the following steps:

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

[0079] The aforementioned first device can be a terminal or a network-side device.

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

[0081] The above-mentioned signals are signals used for measurement. For sensing measurements, the above-mentioned signals are sensing signals; for communication measurements, the above-mentioned signals are communication signals. The sensing signals may include at least one of the following:

[0082] Specialized sensing signals, such as sensing signals generated based on chirp or frequency modulated continuous wave (FMCW) signals, or sensing signals generated based on pseudo-random (PN) sequences, ZC sequences, or other constant envelope zero autocorrelation (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), etc.

[0084] Synchronization signals, such as the primary synchronization signal (PSS) or the secondary synchronization signal (SSS);

[0085] Signals that carry communication data, such as 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 aforementioned signals can be either single-port or multi-port signals.

[0087] It is understandable that sensing signals and communication signals can be the same or different. For example, for integrated sensing services, sensing signals and communication signals can be the same.

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

[0089] The aforementioned first beam information enables the first device to use a suitable beam for measurement. Specifically, the aforementioned first beam information can indicate signal-related beam information such as the transmit beam, receive beam, beam scanning rules, and beam type.

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

[0091] The aforementioned measurements can be sensing measurements (also known as sensing measurements), communication measurements, or integrated communication and sensing measurements.

[0092] The first device performing the measurement based on the first beam information may be either the first device receiving and measuring the signal based on the first beam information, or the first device measuring the signal based on the first beam information.

[0093] The above results information may include measurement results or performance indicators, such as perception-related measurement results (also known as perception measurement results), communication measurement results, or integrated sensing measurement results, as well as perception-related performance indicators (also known as perception performance indicators), communication performance indicators, or integrated sensing performance indicators.

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

[0095] For sensing measurement, for example, the sensing measurement in this application embodiment can be applied to bistatic sensing. In this scenario, the first device receives first beam indication information sent by the second device, the second device sends a sensing signal to the first device according to the first beam indication information, and the first device receives the sensing signal and performs measurement according to the first beam indication information to obtain the sensing measurement result. Here, the first device and the second device can be a base station (or TRP) or a terminal, such as the second device being a base station and the first device being a terminal; or the second device being a terminal and the first device being a base station; or both the first device and the second device being base stations; or both the first device and the second device being terminals. Additionally, in this scenario, the second device may obtain sensing requirements from a third device. After obtaining the sensing measurement result, the first device can send it to either the first device or the third device. The third device can be a core network sensing network function or a sensing network element.

[0096] For example, the sensing measurement in this application embodiment can be applied to monocentric sensing. In this scenario, the second device sends a first beam indication information to the first device, and the first device sends a sensing signal and receives an echo signal according to the first beam indication information to perform measurement and obtain the sensing measurement result. The second device can be a core network sensing network function or a sensing 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 sensing performance or improve sensing performance, the transmit and receive beams need to be pointed to the sensing target or area during the sensing measurement process. In other words, during the sensing measurement process, the transmit and receive beams need to cover the sensing target or the sensing area. Figures 5 and 6 are schematic diagrams of the sensing target or area and the corresponding transmit and receive beams in bistatic sensing and monostatic sensing scenarios, respectively.

[0098] Figure 5(a) shows the beam covering a specific area, Figure 5(b) shows the beam covering a specific target, Figure 6(a) shows the beam covering a specific area, and Figure 6(b) shows the beam covering a specific target.

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

[0100] In this embodiment, a first device acquires first beam indication information sent by a second device. The first beam indication information is used to indicate the first beam information of a signal. The first device performs measurements based on the first beam information to obtain result information. Since the first beam indication information indicates the first beam information of a signal, measurements based on the first beam information make it easier to match the beam information with the measurement, thereby improving measurement performance.

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

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

[0103] The first beam information includes at least one of the following, which can be explicitly or implicitly indicated as including at least one of the first beam information.

[0104] In some embodiments, the aforementioned transmit beam includes the transmit beam associated with the signal, or an active set of transmit beams, wherein the transmit beam associated with the signal is a beam used to transmit the signal, and the transmit beams in the active set of transmit beams are used to transmit the signal.

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

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

[0107] By using the aforementioned signal-associated transmit beams or the set of activated transmit beams, a one-time indication signal transmit beam can be achieved. Subsequent transmit beam switching or beam scanning will not require further indication, thus saving indication signaling overhead.

[0108] In some embodiments, the receiving beam includes the signal-associated receiving beam, or an active set of receiving beams, wherein the signal-associated receiving beam is a beam for receiving the signal, and the receiving beams in the active set of receiving beams are used to receive the signal.

[0109] The aforementioned signal-associated receiving beam can be understood as all receiving beams associated with the signal, i.e., all receiving beams used to transmit the aforementioned signal. The beam used to receive the signal can be understood as any beam that can be used to receive the aforementioned signal, i.e., these receiving beams are all beams that can be used to receive the aforementioned signal; or the beam used to receive the signal can be understood as the receiving beam among these beams that ultimately receives the aforementioned signal. The use of receiving beams in the aforementioned active set of receiving beams to receive the signal means that the first device uses the receiving beams in this set to receive the signal.

[0110] By using the aforementioned signal-associated receiving beams or the set of activated receiving beams, a one-time indication signal receiving beam can be achieved. Subsequent receiving beam switching or beam scanning will not require further indication, thus saving indication signaling overhead.

[0111] In some implementations, the first device can determine the other based on the transmit beam and the receive beam, that is, determine the transmit and receive beam pair information. For example, in Figure 5(a), through beam training or other historical measurement information, the first device determines that the best receive beam corresponding to transmit beams Beam#3 and #4 is Beam#2, and the best receive beam corresponding to transmit 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 for transmitting the signal, a transmission beam 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 for receiving the signal, and an activated receiving beam.

[0115] Wherein, the transmitting beam that transmits the signal refers to the transmitting beam that is currently transmitting the signal, and the transmitting beam that will transmit the signal in the future may be the transmitting beam that transmits the signal within a preset time range in the future, or the transmitting beam that transmits the signal in subsequent measurements.

[0116] The activated transmit beam can be the transmit beam currently used for measurement.

[0117] Dynamic beam indication can be achieved by indicating at least one of the following: the transmission beam of the aforementioned transmitted signal, the transmission beam of the signal to be transmitted, and the active transmission beam. For example, the second device dynamically indicates the transmission beam of the signal according to the characteristics of the sensing service, thereby enabling more flexible real-time beam adjustment during the measurement process. In scenarios where target tracking and sensing are performed, considering the mobility of the target, dynamic beam indication can ensure sensing performance, achieve on-demand configuration, and save resources.

[0118] The receiving beam that will receive the signal mentioned above can be a receiving beam that receives signals within a preset time range in the future, or a receiving beam that receives signals in subsequent measurements. The activated receiving beam mentioned above can be the receiving beam used in the current measurement.

[0119] Dynamic indication of the receiving beam can be achieved by using at least one of the receiving beam that will receive the signal and the activated receiving beam. For example, the second device can dynamically indicate the receiving beam of the signal according to the characteristics of the sensing service, so as to make more flexible real-time beam adjustment during the measurement process. In the scenario of tracking and sensing the target, considering the mobility of the target, dynamic beam indication can ensure sensing performance, realize on-demand configuration, and save resources.

[0120] Optionally, the method further includes:

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

[0122] The signal-associated transmission beam, or the active set of transmission beams, wherein the signal-associated transmission beam is a beam used to transmit the signal, and the transmission beams in the active set of transmission beams are used to transmit the signal; wherein at least one of the transmission beam that transmits the signal, the transmission beam that will transmit the signal, and the active transmission beam is the signal-associated transmission beam or a transmission beam in the active set of transmission beams, or the transmission 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 signal-associated transmission beam or a transmission beam in the active set of transmission beams;

[0123] The signal-associated receiving beam, or the active set of receiving beams, wherein the signal-associated receiving beam is a beam used to receive the signal, and the receiving beams in the active set of receiving beams are used to receive the signal; wherein at least one of the receiving beam that is about to receive the signal and the active receiving beam is the signal-associated receiving beam or the receiving beam in the active set of receiving beams, or the receiving 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 signal-associated receiving beam or the receiving beam in the active set of receiving beams;

[0124] The second beam type is defined as follows: at least one of the transmitting beam that transmits the signal, the transmitting beam that is about to transmit the signal, and the active transmitting beam is of the second beam type; or, at least one of the receiving beam that is about to receive the signal and the active receiving beam is of 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 of the second beam type.

[0125] The aforementioned signal-associated transmit beam, signal-associated receive beam, active transmit beam set, and active receive beam set are described in the corresponding descriptions of the above embodiments, and will not be repeated here.

[0126] Obtaining the second beam indication information means receiving the second beam indication information before receiving the first beam indication information. For example, the second beam indication information first indicates the transmitted beam associated with the signal or the set of active transmitted beams. Then, the first beam indication information indicates the transmitted beam, beam scanning rule, beam switching rule, beam dwell time, and first beam type. This ensures that the transmitted beam corresponding to the transmitted beam, beam scanning rule, beam switching rule, beam dwell time, and first beam type belongs to the transmitted beam associated with the signal or the set of active transmitted beams, thereby improving the indication accuracy of the transmitted beam, beam scanning rule, beam switching rule, beam dwell time, and first beam type. For example, when the beam switching rule indicates beam switching, the first device determines, based on the second beam indication information and the first beam indication information, to perform beam switching on the transmitted beam associated with the signal or the set of active transmitted beams; or, when the first beam indication information indicates beam dwell time, the first device determines, based on the second beam indication information and the first beam indication information, the dwell time of the beams in the transmitted beam associated with the signal or the set of active transmitted beams, and then determines the beam used at each time; or, when the first beam indication information indicates a first beam type, the first device determines the transmitted beam of the first beam type in the transmitted beam associated with the signal or the set of active transmitted beams.

[0127] For example, the second beam indication information first indicates the signal-associated receiving beam or the active set of receiving beams. Then, the first beam indication information indicates the receiving beam, beam scanning rule, beam switching rule, beam dwell time, and first beam type. This ensures that the receiving beam corresponding to the receiving beam, beam scanning rule, beam switching rule, beam dwell time, and first beam type belongs to the signal-associated receiving beam or the active set of receiving beams, thereby improving the indication accuracy of the receiving beam, beam scanning rule, beam switching rule, beam dwell time, and first beam type.

[0128] For example, the second beam type is first indicated by the second beam indication information. Then, the first beam indication information is used to indicate the transmit beam, receive beam, beam scanning rule, beam switching rule, and beam dwell time. This ensures that the beam type of the transmit beam, receive beam, beam scanning rule, beam switching rule, and beam dwell time belongs to the second beam type, thereby improving the indication accuracy of the receive beam, beam scanning rule, beam switching rule, beam dwell time, and first beam type.

[0129] In this embodiment, the second beam information is indicated first, which allows for simple and convenient dynamic indication of the first beam information. For example, if the second beam information includes an active set of transmit beams, the first beam information only needs to dynamically indicate the transmit beam that transmits the signal, the transmit beam that will transmit the signal, or the active transmit beam; or, if the second beam information includes an active set of receive beams, the first beam information only needs to dynamically indicate the receive beam that will receive the signal or the active receive beam.

[0130] In some implementations, the second beam indication information can be received via higher-layer signaling, such as Radio Resource Control (RRC) signaling. Alternatively, the first beam indication information can be received via layer-1 signaling, such as Downlink Control Information (DCI) signaling. Other signaling transmission methods are also possible, and this application does not limit the specific methods used.

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

[0132] The aforementioned beam switching rules can be switching rules for beams of the same type or different types, and can be switching rules for transmitting beams or receiving beams.

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

[0134] Should beam scanning be performed?

[0135] Scan clockwise or counterclockwise;

[0136] Uniform scan or non-uniform scan;

[0137] Uniform scanning or non-uniform scanning;

[0138] The order of beam scanning;

[0139] Perform periodic scanning according to the beam markings;

[0140] Perform reciprocating scanning according to the beam markings;

[0141] Perform scanning according to the target rules;

[0142] or,

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

[0144] Should beam switching be performed?

[0145] The sequence of beam switching;

[0146] Beam switching cycle.

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

[0148] The aforementioned non-uniform scanning can be characterized by beam pointing offsets before and after beam switching that are not at equal intervals, allowing the specific scanning pattern to be directly indicated by beam markings. Alternatively, the aforementioned uniform scanning can be characterized by beam pointing offsets before and after beam switching that are at equal intervals.

[0149] The non-uniform scanning described above can be characterized by different durations for each beam, while the uniform scanning described above can be characterized by the same duration for each beam.

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

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

[0152] The above-mentioned reciprocating scanning according to the beam identifier can be performed by multiple beams. For example, in Figure 5(b), periodic scanning is performed according to the beam identifier: Beam#3→#5→#6→#5→#3→#5→#6→….

[0153] In this embodiment of the application, the beam identifier can also be a Transmission Configuration Indication (TCI) status identifier, a signal identifier, an area identifier, or a target identifier, etc. For example, if the beam information is indicated by multiple TCI statuses, then the beam scanning / switching rule is the activation order of the multiple TCI statuses associated with the indicator signal.

[0154] The target rule mentioned above can be any other rule besides the one described above, and can be a protocol agreement or a pre-configured rule. For example, the beam switching interval is X beam switching times per scanning cycle, instead of switching to the nearest adjacent beam. For example, in Figure 5(a), the scanning order is: Beam#3→#5→#4→#6→#3→#5→…; or, for example, scanning from the edge of the sensing area to the center, again taking Figure 5(a) as an example, the scanning order is: Beam#3→#6→#4→#5→#3→#6→….

[0155] In some implementations, if a beam switching is not indicated, then a beam switching is not required, and there is no need to re-indicate the active beam information. The aforementioned indication of whether or not to perform beam switching can be dynamic.

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

[0157] The aforementioned beam switching period can indicate the dwell time of the beam, meaning that switching occurs after the dwell time of the beam ends. Furthermore, the aforementioned beam switching period can be a one-time indication or a dynamic indication.

[0158] The aforementioned beam scanning rules or beam switching rules enable the first device to perform measurements based on a more suitable beam, thereby improving measurement performance.

[0159] In some implementations, the aforementioned beam scanning rules or beam switching rules can be dynamically indicated. For example, the second device can dynamically indicate the beam scanning or switching method associated with the signal based on the characteristics of the sensing service. This allows for more flexible real-time beam adjustment during the measurement process. In scenarios where the target is tracked and sensed, considering the mobility of the target, dynamic beam indication can ensure sensing performance, achieve on-demand configuration, and save resources.

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

[0161] In some implementations, 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, which is the time required to calculate one measurement result.

[0163] The beam dwell time is related to the 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] Since the beam dwell time is greater than or equal to the coherent processing time, the first device has sufficient time to calculate the measurement results, thereby improving measurement performance. For example, Tp in Figure 7 represents the signal coherent processing time. The coherent processing time window is the time window for each calculation of the output measurement result (e.g., performing a two-dimensional Fast Fourier Transform (FFT) operation to obtain the time domain resource length corresponding to the distance-Doppler map). One coherent processing time can contain multiple time slots / symbols.

[0166] The above-mentioned relationship between beam dwell time and signal resource interval can be that the beam dwell time is determined based on the signal resource interval. For example, the beam dwell time can be the signal resource interval, as shown in Figure 8 where △T represents the signal time domain resource interval.

[0167] Because beam dwell time is related to signal resource intervals, beam switching or scanning is more easily matched with signal resources, thereby improving measurement performance.

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

[0169] Since the beam dwell time is greater than or equal to X signal resource units, the first device has enough time to calculate the measurement results, thereby improving measurement performance.

[0170] In some implementations, for dynamically indicating first beam information, the beam dwell time can be the duration of the currently active beam, or the duration of the currently active beam can be from the current moment until the next first beam indication information arrives.

[0171] In some implementations, 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, resulting in different signal coherence processing times and different sensing beam durations. The relationship between the coherence processing time and the velocity resolution is as follows:

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

[0173] The first beam type mentioned above can be either a transmitting beam type or a receiving beam type, and the first beam type can include at least one of the following:

[0174] Sensing reference beam, communication beam, sensing beam;

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

[0176] Among them, the sensing reference beam or communication beam, which can be referred to as the first beam type, points in the LOS direction of the transceiver equipment. It remains relatively fixed during the measurement process, but when the transceiver equipment moves, it may involve beam switching or a change in beam direction, such as Beam#0 in Figures 5 and 6. For the above-mentioned first beam type, the beam switching rules corresponding to the beams that meet the direction requirements in the active beam set can be configured to not support beam scanning.

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

[0178] The aforementioned beam types enable the support of measurements using multiple different beam types, thereby improving measurement performance.

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

[0180] Sensing reference beam, communication beam, sensing beam.

[0181] In some implementations, the aforementioned first beam indication information can be used to indicate the associated transmitting beam or the receiving beam used by the first device, as well as the beam scanning or switching method, all at once. This allows the associated transmitting beam to be dynamically changing, used to cover multiple sensing targets or a specific sensing area, as shown in Figures 5 or 6. Furthermore, for sensing systems, beam scanning or dynamic switching is continuously performed according to preset rules during the measurement process. Using this method for beam indication based on the characteristics of the sensing application eliminates the need for real-time beam switching indication, thus saving on indication signaling overhead.

[0182] As an optional implementation, the first beam indication information indicates the first beam information by 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 indicator, beam scan range information, beamwidth 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] Wherein, the aforementioned first beam indication information indicating the first beam information by at least one of the above can mean indicating at least one of the following:

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

[0186] The aforementioned at least one beam identifier can indicate multiple beams at once, or dynamically indicate one beam. For example, in the scenario where the sensing beam covers a specific area as shown in Figure 5(a) or 6(a), it can indicate only the starting beam identifier (Identifier, ID) and the ending beam ID for one beam scanning cycle. For example, in Figure 5(a) or 6(a), subsequent measurements are performed using Beam#3 to Beam#6, so {Beam#3, Beam#6} is indicated.

[0187] In some implementations, the at least one beam identifier may be relative beam index information within the active beam set, based on the second beam indication information, to achieve dynamic beam indication.

[0188] The QCL information mentioned above can indicate the QCL relationship between signals and objects such as resources and antenna ports. For example, the QCL information includes at least one of the following:

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

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

[0191] The QCL relationship information between the aforementioned signal and reference signal resources is used to represent the QCL relationship between the signal and the reference signal resources. This QCL relationship indicates that the beam associated with the reference signal resource is the beam associated with the aforementioned signal. For example, the aforementioned QCL relationship information indicates a list of reference signal IDs that satisfy the spatial QCL relationship (QCL-TypeD) with the signal. Specifically, this can be configured through TCI status indication, such as configuring multiple TCI states for the signal and activating them simultaneously to indicate beam scanning, or using an active TCI state to indicate that the signal satisfies the QCL-TypeD relationship with multiple reference signals.

[0192] The QCL relationship information between the signal and the antenna port is used to represent the QCL relationship between the signal and the antenna port, so that the beam associated with the antenna port is the beam associated with the signal.

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

[0194] The aforementioned beam set index can be obtained by grouping all beams supported by the first device into multiple beam sets, and assigning an index or ID to each beam set. By indicating the corresponding beam set index, a set of beams used for measurement can be indicated. Among them, grouping all beams can be based on sensing areas. For example, in Figure 5(a), Beam#3 to Beam#6 is beam set #1, corresponding to area #1, and Beam#1 to Beam#2 is beam set #2, corresponding to area #2.

[0195] By using the aforementioned beam set index to indicate the first beam information, signaling overhead can be saved.

[0196] The bitmap indication mentioned above can be based on a preset beam set, and the bitmap indicates the beam activated in subsequent measurements. For example, in Figure 5(b), for the preset beam set Beam#1 to #6, if subsequent measurements use Beam#3, #5, and #6, then the bitmap information {001011} is indicated. The bitmap indication can save signaling overhead.

[0197] Among them, the beam ID and the corresponding beam parameters in the above-mentioned preset beam set are known to both the first device and the second device.

[0198] The aforementioned beam scanning range information can directly indicate the range of beam scanning during subsequent measurements, such as the azimuth or elevation range. Using beam scanning range information simplifies the indication of the first beam information, enabling the first device to perform measurements based on the corresponding beam.

[0199] The aforementioned beamwidth information can be a direct indication of the beamwidth during subsequent measurements, such as horizontal or vertical beamwidth. The beam scanning range information can more simply indicate the first beam information, so that the first device can perform measurements based on the corresponding beam.

[0200] The aforementioned beam switching offset can be a direct indication of the angular offset of the adjacent beams during subsequent measurements. In this way, the beam switching offset can more accurately indicate the adjacent beams associated with the signal, so that the first device can perform measurements based on the corresponding beams.

[0201] In some implementations, the aforementioned beam scanning range information, beamwidth information, or beam switching offset can be based on existing preset beam set information, indicating the beam activated for subsequent measurements through the beam scanning range information, beamwidth information, or beam switching offset; or, the beam scanning range information, beamwidth information, or beam switching offset can be directly determined based on the beam scanning angle range, beamwidth, and angle offset to determine the activated beam.

[0202] In some implementations, the aforementioned beam switching offset indicates relative offset information based on the previously activated beam. This offset can be an offset in the beam pointing angle or an offset in the beam index. For example, in Figure 5(a), if the previously activated beam was Beam#4 and the currently activated beam is Beam#3, then the beam index offset could be -1. Alternatively, if the previously activated beam was Beam#4 and the currently activated beam is Beam#5, then the beam index offset could be +1. Thus, the beam switching offset can dynamically indicate the transmitting or receiving beam of the signal.

[0203] The aforementioned coverage area information can be a mapping relationship between the coverage area and the beam, thus indicating the corresponding beam through the coverage area information. For example, the area supported by the first device can be divided into different sub-regions, each with a specific identifier ID associated with a specific beam. The beam information used can be indicated by the indicating region ID. For instance, with the first device as the origin, its coverage area can be rasterized into multiple sensing regions, each region associated with a region ID, as shown in Figure 9. The dashed line represents the coverage area of ​​the first device, and each square represents a divided sensing region.

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

[0205] The aforementioned target tracking information can indicate the target information that needs to be tracked, and a mapping relationship is pre-established between the target and the beam, with different beams used to track different targets. For example, based on prior target information (which may be obtained from historical measurements), a specific identifier ID is assigned to different targets, and the beam information used is indicated by indicating the target ID.

[0206] By implicitly indicating the first beam information through tracking target information, signaling overhead can be reduced.

[0207] The aforementioned antenna panel information, antenna subarray information, transmit channel information, or receive channel information refers to the mapping relationship between these information and beam information. This allows the antenna panel information, antenna subarray information, transmit channel information, or receive channel information to indicate the corresponding beam information. This implicit indication of beam information through the antenna panel information, antenna subarray information, transmit channel information, and receive channel information reduces signaling overhead.

[0208] The signal configuration information of the above signal can be a beam associated with at least one signal resource, so that the corresponding beam information can be indicated for different signals. For example, different signal resources can be associated with different beams in the signal configuration information, and the beam scanning process can be realized by configuring multiple signal resources. The relationship between the signal and the transmitting (or receiving) beam can be 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 no additional configuration information is needed to indicate the first beam information.

[0210] In some implementations, the signal configuration information of the above signal may be an explicit or implicit indication of the first beam information. For example, the signal configuration information may include the first beam information.

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

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

[0213] The above N signals corresponding to N directions of transmission beams can be multiple signals corresponding to multiple transmission beams in different directions, that is, multiple signals are transmitted using different spatial filters and are associated with a specific receiving beam.

[0214] The above N signals correspond to M receiving beams in different directions. Some signals may correspond to receiving beams in the same direction, or some signals may correspond to receiving beams in different directions.

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

[0216] In some implementations, the N directions are associated with the sensing angle range, or the M directions are associated with the sensing angle range.

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

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

[0219] In some implementations, when a first signal is transmitted in 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 plurality of time units is greater than or equal to the coherent processing duration, or the duration of the plurality of time units is greater than or equal to the coherent processing duration, wherein the coherent processing duration is the duration for calculating one measurement result;

[0221] The time interval between two adjacent time units in the plurality of time units satisfies the requirements for Doppler unambiguous measurement or velocity unambiguous measurement.

[0222] The first signal transmitted in multiple time units can be understood as the first signal occupying multiple time units, such as occupying multiple symbols, sub-slots, time slots, subframes, etc.

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

[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 multiple time units meets the requirements for Doppler unambiguous measurement or velocity unambiguous measurement, the first device can perform measurement based on the first signal, making the measurement results more reliable.

[0226] The aforementioned requirement for unambiguous Doppler measurement or unambiguous velocity measurement can be agreed upon by the protocol or configured on the network side, for example:

[0227] For monostatic sensing:

[0228] If the direction of velocity is considered, the time interval satisfies ΔT≤1 / (2|f) dmax |) or If we disregard the fact that the velocity direction and time interval satisfy ΔT≤1 / f dmax or Where f dmaxFor the maximum unambiguous Doppler, v max For the maximum unambiguous velocity, f c denoted as carrier frequency, and c as the speed of light.

[0229] For bistatic sensing:

[0230] If the direction of velocity is considered, the time interval satisfies ΔT≤1 / (2|f) dmax |) or If we disregard the fact that the velocity direction and time interval satisfy ΔT≤1 / f dmax or β is the bibase angle.

[0231] In some implementations, 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 distance resolution.

[0232] or,

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

[0234] The second signal transmitted 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 embodiment, 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 the measurement performance.

[0236] The aforementioned requirement for unambiguous delay or unambiguous distance measurement can be stipulated by protocol or configured by network-side equipment. Frequency domain spacing Δf ≤ 1 / τ max Or Δf≤c / (2R) max ), where τ max For the maximum unambiguous delay, v max The maximum unambiguous distance.

[0237] Since the frequency domain spacing of the two frequency domain units meets the requirements for unambiguous time delay measurement or unambiguous distance measurement, the first device can perform measurement based on the first signal, making the measurement results more reliable.

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

[0239] Signal resource identifier, signal purpose, waveform, subcarrier spacing, guard interval, frequency domain start position, frequency domain resource length, frequency domain resource interval, time domain start 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 aforementioned signal resource identifiers are used to distinguish different signal resource configurations;

[0241] The above-mentioned signal usage indicates that the target signal is used for communication (e.g., channel measurement, channel estimation, synchronization, carrying data information, etc.), for sensing, or for both communication and sensing. Specifically, it can also be a signal used for a particular sensing service, or a signal used for a particular type of sensing service.

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

[0243] Target presence detection, location, velocity detection, distance detection, angle detection, acceleration detection, material analysis, composition analysis, shape detection, classification, and radar cross section (RCS). The sensing services include: Section (RCS) detection, polarization scattering characteristic detection, fall detection, intrusion detection, quantity statistics, indoor positioning, gesture recognition, lip reading, gait recognition, facial expression recognition, respiration monitoring, heart rate monitoring, pulse monitoring, humidity / brightness / temperature / atmospheric pressure monitoring, air quality monitoring, weather condition monitoring, environmental reconstruction, terrain and landform, building / vegetation distribution detection, pedestrian or vehicle flow detection, crowd density, vehicle density detection, etc. The sensing service types can be classified according to certain characteristics, such as by function (detection-type sensing services, including intrusion detection and fall detection), parameter estimation-type sensing services (distance, angle, and speed calculation), and recognition-type sensing services (action recognition, identity recognition), etc. They can also be classified by sensing range (near-range sensing, medium-range sensing, and long-range sensing), by sensing fineness (coarse-grained sensing, fine-grained sensing, etc.), by power consumption / energy consumption, and by resource usage, etc.

[0244] The waveforms mentioned above can be OFDM, Single-carrier Frequency-Division Multiple Access (SC-FDMA), Orthogonal Time Frequency Space (OTFS), Frequency Modulated Continuous Wave (FMCW), or pulse signals, etc.

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

[0246] The aforementioned guard interval can be the time interval from the moment the signal ends transmission to the moment the latest echo signal of that signal is received, and this parameter is proportional to the maximum sensing distance; for example, it can be expressed as c / (2R). max )Calculations show that R max For the maximum sensing distance (belonging to sensing demand information), such as for self-transmitted and self-received signals, R max This represents the maximum distance from the signal transmission / reception point to the signal reflection point; in some cases, the OFDM signal cyclic prefix (CP) can serve as a minimum guard interval, where c is the speed of light.

[0247] The starting position in the frequency domain can be the starting frequency point, or it can be the starting resource element (RE) or resource block (RB) index.

[0248] The aforementioned frequency domain resource length can be the frequency domain bandwidth, which is inversely proportional to the distance resolution. The frequency domain bandwidth of each signal is B≥c / (2ΔR), where c is the speed of light and ΔR is the distance resolution.

[0249] The frequency domain resource interval mentioned above represents the interval between adjacent signal frequency domain resource units, which can be represented by the number of REs or RBs, or by a density value. For example, Density = 1 means that there is one RE in each RB used to carry the signal. The frequency domain resource interval is inversely proportional to the maximum unambiguous distance / delay. For OFDM systems, when the subcarriers are continuously mapped, the frequency domain interval is equal to the subcarrier interval.

[0250] The aforementioned starting position in the time domain can be the starting time point, or it can be the starting symbol, time slot, or frame index.

[0251] The aforementioned time-domain resource length can be the burst duration, and the time-domain resource length is inversely proportional to the Doppler resolution.

[0252] The aforementioned time-domain resource interval can be the time interval between two adjacent signal resource units, and the time-domain resource interval is related to the maximum unambiguous Doppler frequency shift or the maximum unambiguous velocity.

[0281] In some embodiments, the first indicator mentioned above may be the linear average value (in W) of the received power of the path associated with the sensing target in the channel response measured from the sensing signal over the resource unit carrying the sensing signal. This resource unit may be a time-domain or frequency-domain resource unit. Using a linear average value makes the received power more accurate and reliable. It should be noted that the embodiments of this application do not limit the received power to a linear average value. For example, in some embodiments, it may also be the median received power, the lowest received power, or the highest received power.

[0282] The aforementioned sensing signals are the signals measured by the first device, such as dedicated signals used for sensing services, or communication signals such as reference signals, synchronization signals, etc.

[0283] The aforementioned perception metrics related to interference or noise power include at least one of the following:

[0284] The second indicator is the sum of a first linear average and a second linear average. The first linear average is the linear average of the power of paths other than the path associated with the sensing target in the channel response of the sensing signal on the target resource. The second linear average is the linear average of the interference or noise power from other signals other than the sensing signal on the first resource. Alternatively, the second indicator is equal to the difference between the total received power and the first indicator, where the total received power is the total received power of the first device on the target resource.

[0285] The third indicator is the linear average of the interference or noise power from signals other than the sensing signal on the second resource, or the third indicator is equal to the difference between the total received power and the received power of the sensing signal, where the total received power is the total received power of the first device on the target resource.

[0286] The fourth indicator is the linear average power of the paths other than the path associated with the sensing target in the channel response of the sensing signal on the target resource; or, the fourth indicator is equal to the difference between the received power of the sensing signal and the first indicator mentioned above.

[0287] Wherein, the first index is used to indicate the received power of the path of the sensing signal associated with the sensing target, the target resource is the transmission resource of the sensing signal, the first resource includes the target resource or at least one resource other than the target resource, and the second resource includes the target resource or at least one resource other than the target resource.

[0288] The other paths mentioned above can be all or part of the paths in the sensing signal other than those associated with the sensing target.

[0289] Other signals besides the aforementioned sensing signals can refer to all or part of the signals detected by the first device on the first resource, excluding the sensing signals.

[0290] The aforementioned first resource, including the target resource or at least one resource other than the target resource, means that the first resource includes at least one of the following:

[0291] The target resource, and at least one other resource besides the target resource.

[0292] The aforementioned second resource, including the target resource or at least one resource other than the target resource, means that the second resource includes at least one of the following:

[0293] The target resource, and at least one other resource besides the target resource.

[0294] In this context, at least one resource other than the target resource can refer to at least one resource other than the target resource among the resources that the first device needs to detect or receive signals from, such as resources configured by higher-layer signaling or resources that the first device has predetermined to detect or receive signals from.

[0295] The aforementioned interference or noise power includes the sum of interference power and noise power, or interference power or noise power.

[0296] The total received power of the first device on the target resource may include the received power of signals from the serving cell and non-serving cells on the target resource, adjacent channel interference power, and thermal noise power, etc. Furthermore, the total received power may also be a linear average of the total received power of the first device on the target resource (in W).

[0297] The power corresponding to the Received Signal Strength Indication (RSSI) of the first device on the first resource can be the total received power = RSSI * K1, where K1 is a coefficient, which can be a protocol convention or a network-side configuration. In some embodiments, the power corresponding to the RSSI can also be the RSSI itself, i.e., total received power = RSSI.

[0298] The received power of the sensing signal mentioned above refers to the reference signal received power (RSRP) of the sensing signal.

[0299] The second indicator mentioned above is equal to the difference between the total received power and the first indicator, which can be expressed as: Second indicator = Total received power - First indicator.

[0300] The third indicator mentioned above is equal to the difference between the total received power and the received power of the sensed signal, which can be expressed as: Third indicator = Total received power - Sensed signal received power.

[0301] The fourth index mentioned above is equal to the difference between the received power of the sensing signal and the first index, which can be expressed as: Fourth index = Received power of sensing signal - First index.

[0302] In the above embodiments, the second index allows interference or noise from other paths besides the path associated with the sensing target and other signals besides the sensing signal to be considered when determining measurement switching, thus making measurement switching more reliable.

[0303] In the above embodiments, the third indicator allows interference or noise from signals other than the sensing signal to be considered when determining measurement switching, thus making measurement switching more reliable.

[0304] In the above embodiments, the fourth index allows the power of other paths besides the path associated with the sensing target to be considered when determining measurement switching, which makes measurement switching more reliable.

[0305] The aforementioned perception index, which is related to both received power and interference or noise power, refers to a perception index that is related to both received power and interference or noise power.

[0306] In some implementations, the aforementioned sensing metrics related to received power, and also related to interference or noise power, include at least one of the following:

[0307] The fifth indicator is equal to the quotient obtained by dividing the first indicator by the second indicator.

[0308] The sixth indicator is equal to the quotient obtained by dividing the first indicator by the third indicator.

[0309] The seventh indicator is equal to the quotient obtained by dividing the first indicator by the fourth indicator.

[0310] The eighth index is equal to the product of the quotient obtained by dividing the first index by the total received power and the target coefficient;

[0311] Wherein, 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 are the same as those described in the above implementation method, and will not be repeated 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 this application may or may not include the first, second, third, and fourth indicators.

[0313] The aforementioned target coefficient can be represented as K2, such as the eighth indicator = K2 * the first indicator / total received power, where K2 is the coefficient, and K2 can be a protocol agreement or a network-side configuration.

[0314] In this embodiment, by using the fifth, sixth, seventh, or eighth indicators mentioned above, the receiving power and interference or noise can be taken into account when determining the measurement switch, so as to make the measurement switch more reliable.

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

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

[0317] In some implementations, the path associated with the perceived 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 the second preset range;

[0321] The parameter difference with the reference path meets the third preset threshold, or the parameter difference with the reference path is within the third preset range.

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

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

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

[0325] Amplitude difference, power difference, intensity difference, energy difference, phase difference, Doppler difference, time delay difference, and angle difference.

[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 can be agreed upon by the protocol or configured on the network side. Alternatively, these preset thresholds or preset interval ranges can be determined by the receiving device based on prior sensing information or sensing requirements. The parameters satisfying the first preset threshold can be defined as the parameters exceeding or equaling the first preset threshold. The parameter difference with the first path satisfying the second preset threshold can be defined as the parameter difference with the first path exceeding or equaling the second preset threshold. The parameter difference with the reference path satisfying the third preset threshold can be defined as the parameter difference with the reference path exceeding or equaling the third preset threshold.

[0327] For example, if the sensing service is moving target detection, then the path with a Doppler greater than zero needs to be detected as the path associated with the sensing target; or for a traffic scenario where the sensing target is a vehicle, with a default vehicle speed of 40km / h to 120km / h, then the path within the corresponding speed range (Doppler range) needs to be detected as the path associated with the sensing target; or if the distance between the sensing target area and the sensing signal transceiver needs to meet specific requirements, then the path within the corresponding time delay range needs to be detected as the path associated with the sensing target; or if the sensing service is respiratory monitoring, then the normal breathing rate can be determined based on the person's gender and age (e.g., 15 to 30 breaths / minute, which can be used as prior information for sensing, and the corresponding Doppler range of 0.25 to 0.5Hz can be calculated).

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

[0329] The aforementioned preset modulation rules can be agreed upon by the protocol or configured on the network side. Specific modulation rules are the modulation rules of tags, backscatter devices, or RIS, that is, the path associated with the sensed target can be a path that has been modulated and reflected by tags, backscatter devices, or RIS.

[0330] In one of the above optional embodiments, the path associated with the perceived target can be determined in multiple ways, which can improve the flexibility of determining the path associated with the perceived target, and can also improve the accuracy of determining the path associated with the perceived target by combining multiple methods.

[0331] In some implementations, before determining the path associated with the sensed target, a set of paths can be determined, including paths whose amplitude, power, intensity, or energy exceeds a certain threshold, as shown in Figure 12. This set of paths includes paths 0, 1, 2, and 3. The path associated with the sensed target is then determined from this set based on at least one of the aforementioned criteria, thus reducing computational complexity.

[0332] The following example illustrates the calculation of indicators in the embodiments of this application. It should be noted that the calculation of each indicator in the embodiments of this application is not limited, and the following example is only an illustration.

[0333] The first indicator is calculated in the following way:

[0334] The first device (such as a terminal) performs channel estimation based on the transmitted sensing signal X(k) and the corresponding received signal Y(k) to obtain the 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 to the first dimension and determines the path associated with the sensing target in the first dimension. Then, it calculates the power of the path associated with the sensing target as the first index. If the path associated with the sensing target includes multiple paths, the sum of the power of the multiple paths is calculated as the first index.

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

[0336] Time delay dimension;

[0337] Dopplerweis;

[0338] Azimuth dimension;

[0339] Pitch angle;

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

[0341] For example, H(f) is the channel response, where f = 0, 1, 2, ..., N-1 represents the frequency domain sampling points (e.g., subcarrier index). Then, by performing an inverse Fourier transform on H(f), it can be transformed to the time delay dimension (the first dimension). As another example, H(f,t) is the channel response, where f = 0, 1, 2, ..., N-1 represents the frequency domain sampling points (e.g., subcarrier index), and t = 0, 1, 2, ..., M-1 represents the time domain sampling points (e.g., OFDM symbol index). Then, by performing an inverse Fourier transform along the frequency domain and a Fourier transform along the time domain, it can be transformed to the time delay dimension. The first dimension is the delay-Doppler dimension. For example, H(f,t,s) is the channel response, where f = 0,1,2,…,N-1 represents the frequency domain sampling points (e.g., subcarrier index), t = 0,1,2,…,M-1 represents the time domain sampling points (e.g., OFDM symbol index), and s = 0,1,2,…,P-1 represents the spatial domain sampling points (antenna index or port index). Then, by performing an inverse Fourier transform along the frequency domain dimension, a Fourier transform along the time domain dimension, and a Fourier transform along the antenna domain dimension on H(f,t,s), it can be transformed to the delay-Doppler-angle dimension (the first dimension).

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

[0343] Determine the path set. The paths in the path set include those whose amplitude, power, intensity, or energy exceeds a certain threshold after the channel response is transformed to the first dimension. For example, in Figure 12, paths 0, 1, 2, and 3 are paths in the path set; the certain threshold can be set to be higher than a noise threshold or a noise interference threshold, or as agreed upon by the protocol. This step (determining the path set) is optional; it can be done solely based on the next step to determine the paths associated with the sensing target.

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

[0345] The amplitude, power, intensity, or energy of the noise exceeds a preset threshold or falls within a preset range, such as a preset threshold that exceeds 5 times the noise threshold.

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

[0347] The path delay exceeds a preset threshold or falls within a preset range;

[0348] The angle of the radius exceeds the preset threshold or falls within the preset range;

[0349] The difference in amplitude / power / intensity / energy between the path and the first-reach path (e.g., the LOS path) or the reference path exceeds a preset threshold or is within a preset range. The reference path can 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 path (e.g., the LOS path) or the reference path exceeds a preset threshold or falls within a preset range;

[0351] The time delay difference between the path and the first path (e.g., the LOS path) or the reference path exceeds a preset threshold or falls within a preset range;

[0352] The angle difference between the diameter and the first-arrival diameter (e.g., the LOS diameter) or the reference diameter exceeds a preset threshold or falls within a preset range.

[0353] The amplitude, power, intensity, energy, or phase of the path satisfies a specific modulation rule, which is the modulation rule of the Tag / Backscatter device or RIS. That is, the path associated with the sensing target can be a path that has been modulated and reflected by the Tag / Backscatter device or RIS.

[0354] Among them, the first condition of each of the above can also be based on the statistical results over a period of time; for example, the proportion of the above indicators (such as Doppler of the path, delay of the path, etc.) exceeding the preset threshold or falling within the preset range within the preset time window reaches the preset proportion, or the number of times the above indicators (such as Doppler of the path, delay of the path, etc.) exceed the preset threshold or fall within the preset range within the preset time window reaches the preset number.

[0355] The preset threshold or set range is sent to the receiving device by other devices, and determined by those devices based on prior sensing information or sensing requirements. Alternatively, the preset threshold or preset range can be agreed upon in a protocol, or it can be determined by the receiving device based on prior sensing information or sensing requirements.

[0356] Among them, prior information for perception or perception needs includes the following information:

[0357] Sensing services or types of sensing services, such as detecting the presence of a target, localization, velocity detection, distance detection, angle detection, acceleration detection, material analysis, composition analysis, shape detection, category classification, and radar cross section (RCS). The sensing services include: Section (RCS) detection, polarization scattering characteristic detection, fall detection, intrusion detection, quantity statistics, indoor positioning, gesture recognition, lip reading, gait recognition, facial expression recognition, respiration monitoring, heart rate monitoring, pulse monitoring, humidity / brightness / temperature / atmospheric pressure monitoring, air quality monitoring, weather condition monitoring, environmental reconstruction, terrain and landform, building / vegetation distribution detection, pedestrian or vehicle flow detection, crowd density, vehicle density detection, etc. The sensing service types can be classified according to certain characteristics, such as by function (detection-type sensing services, including intrusion detection and fall detection), parameter estimation-type sensing services (distance, angle, and speed calculation), and recognition-type sensing services (action recognition, identity recognition), etc. They can also be classified by sensing range (near-range sensing, medium-range sensing, and long-range sensing), by sensing fineness (coarse-grained sensing, fine-grained sensing, etc.), by power consumption / energy consumption, and by resource usage, etc. If the sensing service is respiratory monitoring, the corresponding normal respiratory rate can be determined based on the person's gender and age (e.g., 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 prior information for sensing.

[0358] Perception target area: refers to the location area of ​​the perceived object, or the location area that needs to be imaged or reconstructed; for example, a preset range of time delay for determining the path associated with the perceived target based on the approximate location / distance of the perceived object.

[0359] Sensing object type: Sensing objects are classified according to their possible motion characteristics. Each sensing object type contains information such as the motion velocity range, motion acceleration range, and typical RCS range of typical sensing objects.

[0360] The number of perceived targets; for example, the number of perceived targets can be obtained from the camera's perception results as a priori information.

[0361] For example, in Figure 12, paths 0, 1, 2, and 3 are paths in the path set, where paths 2 and 3 are sensing paths that satisfy the first condition (e.g., their time delay meets a preset threshold), and paths 0 and 1 are paths associated with other scatterers.

[0362] Figure 12 shows a multipath diagram of the channel response in the first dimension (time delay dimension, Doppler dimension, azimuth dimension, or elevation dimension), where the horizontal axis represents the first dimension and the vertical axis represents the normalized amplitude, power, intensity, or energy.

[0363] For frequency range 1, the reference point for the first indicator can be the antenna connector of the receiving device, such as the terminal. For frequency range 1, if the receiving device has multiple receiving channels, the first indicator measured and reported by the receiving device cannot be lower than the indicator of any single receiving channel. For frequency range 2, the first indicator measured for a certain receiving channel needs to be obtained by measuring the combined signal on multiple antenna elements corresponding to that receiving channel.

[0364] The second method for calculating the first indicator can be as follows:

[0365] When calculating the received power of the path associated with the perceived target, it can also be the power of the path associated with the perceived target in the first dimension and... The difference is used as the first indicator, where N1 represents the number of paths associated with the perceived target. The average power of multiple paths outside the set of paths in the first dimension.

[0366] Method 1 for calculating the received power of the sensing signal can be as follows:

[0367] The received power of the sensing signal can be obtained by the receiving device after obtaining the channel response H(k), transforming it to the first dimension, determining the path set in the first dimension, and then calculating the sum of the power of all paths in the path set.

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

[0369] The received power of the sensed signal can also be the sum of the powers of all paths in the path set in the first dimension. The difference, where N2 represents the number of paths in the path set.

[0370] How to calculate total received power:

[0371] Total received power

[0372] Where Y(k) is the received signal corresponding to the sensing 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 The received signal Y after the first filtering process is calculated from the received signal X(k) and the sensing signal X(k). filter1 (k), i.e., Y filter1 (k)=H filter1 (k)X(k). Then subtract the received signal Y(k) after the first filtering process from the received signal Y(k). filter1 (k) thus obtaining the interference and noise signal Y σ1 (k), i.e., Y σ1 (k)=Y(k)-Y filter1 (k), and then calculate the second index:

[0375] The first filtering process is used to eliminate noise and interference in the first dimension, as well as paths associated with non-perceived targets. For example, the first filtering process sets the amplitude, power, intensity, or energy of paths other than those associated with perceived targets in Figure 12 to zero. The channel response H after the first filtering process... filter1 (k) does not contain noise and interference, nor does it contain paths associated with non-perceived targets; it only contains paths associated with perceived targets.

[0376] The third indicator can be calculated in the following way:

[0377] The channel response H(k) is processed by a second filter to obtain H. filter2 (k), then according to H filter2 The received signal Y after the second filtering process is calculated from the received signal X(k) and the sensing signal X(k). filter2 (k), i.e., Y filter2 (k)=H flter2 (k)X(k). Then subtract the received signal Y(k) after the second filtering process from the received signal Y(k). flter2(k) thus obtaining the interference and noise signal Y σ2 (k), i.e., Y σ2 (k)=Y(k)-Y filter2 (k), and then calculate the third index:

[0378] The second filtering process described above can be noise interference suppression processing in the first dimension (e.g., setting the amplitude, power, intensity, or energy of other paths besides the path set in Figure 12 to zero), or minimum mean squared error (MMSE) filtering. The channel response H after the second filtering process... filter2 (k) does not contain noise and interference, but only contains paths from the path set.

[0379] The third indicator can be calculated in the following way:

[0380] Based on the average power of multiple diameters outside the first dimension's mid-diameter set The third index P was calculated. 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 identifies multiple sensing targets, or if 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) for each sensing target separately. For example, in Figure 12, determine the paths associated with each sensing target, and then calculate the perception-related indicators for each sensing target. When calculating the second indicator for a certain sensing target (such as sensing target A), there are two methods: namely, the second indicator of sensing target A = total received power - the first indicator of sensing target A; or, the second indicator of sensing target A = total received power - the first indicator of sensing target A - the first indicator of sensing target B; (assuming there are two sensing targets: A and B). Similarly, there are two ways to calculate the fourth indicator: the fourth indicator of sensing target A = the RSRP of the sensing signal - the first indicator of sensing target A; or, the fourth indicator of sensing target A = the RSRP of the sensing signal - the first indicator of sensing target A - the first indicator of sensing target B; (assuming there are two sensing 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 define these paths as 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 this virtual perception target.

[0384] As an optional implementation, the first beam indication information is associated with at least one of the following:

[0385] Measurement requirement information, capability information of the first device, and prior information of the measurement target.

[0386] The aforementioned measurement requirement information can be either sensing measurement requirement information or communication measurement requirement information.

[0387] The aforementioned prior information of the measurement target can be prior information of the sensing target or prior information of the communication measurement target.

[0388] Wherein, the association of the first beam indication information with the above-mentioned at least one means that the first beam indication information is determined based on the above-mentioned at least one, or the first beam information indicated by the first beam indication information is matched with the above-mentioned at least one.

[0389] This allows for determining all or part of the first beam information based on measurement requirement information, resulting in a better match between the measurement and sensing requirements of the first device and improved measurement performance. Similarly, determining all or part of the first beam information based on the first device's capability information further enhances the match between the measurement performed by the first device and its capabilities, thus improving measurement performance. Finally, determining all or part of the first beam information based on prior information about the measurement target also ensures a better match between the measurement and sensing requirements of the first device, further improving measurement performance.

[0390] The aforementioned perceived demand information includes at least one of the following:

[0480] It should be noted that this embodiment is an implementation of the second device corresponding to the embodiment shown in FIG4. For the specific implementation, please refer to the relevant description of the embodiment shown in FIG4. In order to avoid repeated description, this embodiment will not be repeated.

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

[0482] Example 1:

[0483] This embodiment provides a one-time indication of the transmitting beam associated with the configured sensing signal or the receiving beam used by the receiving device, as well as a method for beam scanning or switching. That is, the transmitting beam associated with the sensing signal is dynamically changing, used to cover multiple sensing targets or a specific sensing area, as shown in Figure 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 of beam indication, based on the characteristics of the sensing application, eliminates the need for real-time beam switching indication, thus saving on indication signaling overhead.

[0484] The second device sends a first beam indication message to the first device. The first beam indication message is used to indicate the first beam information used by the first device in sensing measurements. The first beam information includes at least one of transmit beam information and receive beam information. It can be indicated by both separately, or the first device can determine the other one based on one of the transmit beam information and receive beam information, that is, determine the transmit and receive beam pair information. For example, in Figure 5(a), through beam training or other historical measurement information, the first device determines that the optimal receive beam corresponding to transmit beams #3 and #4 is Beam #2, and the optimal receive beam corresponding to transmit beams #5 and #6 is Beam #3.

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

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

[0487] The set of active beams refers to information about the beams that may be used in sensing measurements, 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 could indicate the QCL relationship between the sensed signal and at least one reference signal resource, or antenna port. For instance, it could indicate a list of reference signal IDs that satisfy the spatial QCL relationship (QCL-TypeD) with the sensed signal. Specifically, it could be configured via TCI state indication, such as configuring multiple TCI states for the sensed signal and activating them simultaneously to indicate beam scanning, or indicating that the sensed signal satisfies the QCL-TypeD relationship with multiple reference signals through an active TCI state. Alternatively, for scenarios where the sensed beam covers a specific area as shown in Figure 5(a) or 6(a), it could indicate only the start beam ID and end beam ID of one beam scanning cycle. For instance, if subsequent sensed measurements in Figure 5(a) or 6(a) use Beam#3 to Beam#6 for sensing, then {Beam#3, Beam#6} would be indicated.

[0489] The indicator beam set index is obtained by grouping all beams supported by the device into multiple beam sets and assigning an index or ID to each beam set. By indicating the corresponding beam set index, a set of beams used for sensing measurement can be indicated. The grouping of all beams can be based on the sensing area. For example, in Figure 5(a), Beam#3 to Beam#6 is beam set #1, corresponding to area #1, and Beam#1 to Beam#2 is beam set #2, corresponding to area #2.

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

[0491] This directly indicates the beam scanning range (azimuth range, elevation range) and / or the beamwidth (horizontal beamwidth, vertical beamwidth) and / or the beam switching offset (angle offset of adjacent beams) during subsequent sensing measurements. For example, based on existing preset beam set information, the beam activated for subsequent sensing measurements can be obtained through the beam scanning angle range, or the activated beam information can be directly determined based on the beam scanning angle range, beamwidth, and angle offset. The beam IDs and corresponding beam parameters in the preset beam set are known to both the transmitter and receiver.

[0492] The system indicates the area information that needs to be covered, divides the area supported by the sensing device into different sub-regions, and each sub-region has a specific identifier ID associated with a specific beam. The beam information used is indicated by indicating the region ID. For example, with the base station as the origin, its coverage area is divided into multiple sensing regions by gridding, and each region is associated with a region ID. As shown in Figure 9, the dashed line represents the base station coverage area, and each square represents the divided sensing region.

[0493] It indicates the target information that needs to be tracked. For example, based on the target's prior information (which may be obtained from historical measurements), it assigns a specific identifier ID to different targets and indicates the beam information used by indicating the target ID.

[0494] Indicates panel information or subarray information, which is associated with different beams, or indicates transmit channel or receive channel information;

[0495] The beam scanning / switching rules can be preset (by protocol or pre-configured) for different types of beam scanning / switching rules, indicating which rule to use during measurement.

[0496] The aforementioned preset rules may include at least one of the following:

[0497] Should beam scanning or switching be performed?

[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 at equal intervals. The specific scanning pattern can be directly indicated by the beam ID.

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

[0502] The order information of beam scanning or switching can be indicated by a beam ID list, such as in Figure 5(b), where the beam switching sequence is Beam#3→#5→#6.

[0503] Perform periodic scanning according to the beam ID indication, for example, in Figure 5(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 Figure 5(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, then the beam scanning / switching rule indicates the activation order of the multiple TCI states associated with the sensing signal.

[0506] Alternatively, beam scanning can be performed according to other preset rules, such as switching beams at intervals of X times per scanning cycle instead of switching to the nearest beam, as shown in Figure 5(a), where the scanning order is: Beam#3→#5→#4→#6→#3→#5→…; or scanning from the edge of the sensing area to the center, again taking Figure 5(a) as an example, where the scanning order is: Beam#3→#6→#4→#5→#3→#6→….

[0507] Beam dwell time or switching cycle, which indicates the duration of each beam, can be associated with the corresponding signal resources, such as the number of signal resource units associated with the current beam (e.g., the number of sensing signal symbols).

[0508] The beam dwell time can be no less than a coherent processing duration. For example, Tp in Figure 7 represents the coherent processing duration of the sensing signal. The coherent processing time window is the time window for each calculation of the output sensing measurement result (e.g., performing a two-dimensional FFT operation to obtain the time domain resource length corresponding to the distance-Doppler map). A coherent processing duration can contain multiple time slots / symbols.

[0509] Alternatively, the beam dwell time can be the sensing signal resource interval, for example, △T in Figure 8 represents the sensing signal time domain resource interval.

[0510] Alternatively, the beam dwell time can be no less than the duration of X sensing signal resource units, such as no less than the duration of X sensing signal symbols (including the duration of sensing signal symbols and the interval duration), or no less than X other time units, such as no less than the duration of X OFDM symbols or X time slots, etc.

[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, which correspond to different signal coherent processing times and different sensing beam durations. The relationship between the coherent processing time and the velocity resolution is as follows:

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

[0513] The first beam type can include:

[0514] The sensing reference beam or communication beam points in the LOS direction of the transceiver device and is relatively fixed during the sensing and measurement process. When the transceiver device moves, it may involve beam switching or change of beam direction, 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 active beam set can be configured to not support beam scanning.

[0515] Sensing beams are directed at sensing targets or sensing areas. This type of beam usually needs to support flexible scanning or switching and be dynamically adjusted according to the motion state of the sensing target or the sensing area to be covered, such as Beams #1 to #6 in Figures 5 and 6.

[0516] Before the second device sends beam indication information to the first device, it further includes acquiring the first device's capability information, sensing requirement information, or prior information about the sensing target. The second device determines the aforementioned first beam indication information based on the first device's capability information, sensing requirement information, or prior information about the sensing target.

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

[0518] Information on the maximum number of supported beams or the set of supported beams, or information on the maximum sensing area that can be covered, the maximum sensing angle range, the maximum number of sensing targets, etc.

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

[0520] Supported beamwidth information;

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

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

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

[0524] Number of targets detected;

[0525] Perceive target location information;

[0526] Sensing the location information of the target relative to the transmitting or receiving device;

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

[0528] The first device receives a sensing signal and performs measurements based on the first beam indication information to obtain a measurement result; or, the first device sends a sensing signal, receives the sensing signal echo, and performs measurements 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 metrics related to perception;

[0531] The recommended beam information includes at least one of the following:

[0532] Recommended beam set information for activation;

[0533] Recommended beam scanning rules;

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

[0535] Recommended beam switching step size;

[0536] Recommended beamwidth.

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

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

[0539] Example 2:

[0540] In this embodiment, the beam scanning or switching method associated with the sensing signal is dynamically indicated according to the sensing service characteristics. Compared with Embodiment 1, it can perform real-time beam adjustment more flexibly during the measurement process. For the scenario of tracking and sensing the target based on the prior information of the target in Figure 5(b) or Figure 6(b), considering the mobility of the target, dynamic beam indication can ensure sensing performance, realize on-demand configuration, and save resources.

[0541] The second device sends second beam indication information to the first device (optionally), the second beam indication information indicating all beam information used in the sensing measurement by the first device. The second beam indication information includes at least one of the following:

[0542] The activated beam set information is used to dynamically indicate which beam to activate during beam switching.

[0543] Second beam type.

[0544] The second device sends first beam indication information to the first device. This first beam indication information dynamically indicates the first beam information to be used in subsequent measurements by the first device. The first beam indication information includes at least one of the following:

[0545] The active beam information refers to the beam currently used for measurement. For a specific definition, please refer to the active beam set information. The difference is that the active beam information is only for a single beam. The indicated beam ID information can also be relative beam index information within the active beam set, based on the first beam indication information.

[0546] Alternatively, based on the previously activated beam information, the relative offset information can be indicated. This offset could be the beam pointing angle offset or the beam index offset. For example, in Figure 5(a), if the previously activated beam was Beam#4 and the current activated beam is Beam#3, then the beam index offset could be -1. Or, if the previously activated beam was Beam#4 and the current activated beam is Beam#5, then the beam index offset could be +1.

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

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

[0549] One implementation involves sending the second beam indication information via higher-layer signaling (RRC signaling) and sending the first beam indication information via layer-1 signaling (e.g., DCI signaling). Other signaling transmission methods are also possible, and this embodiment is not limited to any particular method.

[0550] Before the second device sends the first / second beam indication information to the first device, it further includes acquiring the first device's capability information, sensing requirement information, or prior sensing target information. The second device determines the first / second beam indication information based on the first device's capability information, sensing requirement information, or prior sensing target information.

[0551] The first device receives a sensing signal and performs measurements based on the first beam indication information to obtain a measurement result; or, the first device sends a sensing signal, receives the sensing signal echo, and performs measurements based on the first beam indication information to obtain a measurement result, wherein 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 metrics related to perception;

[0554] The recommended beam information includes at least one of the following:

[0555] Recommended beam information to activate;

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

[0557] Recommended beam switching step size;

[0558] Recommended beamwidth;

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

[0560] Similar to Embodiment 1, this embodiment can also be extended to support the simultaneous transmission or reception of multiple beams, thereby improving sensing and measurement efficiency. For example, by configuring multi-port sensing signals or configuring multiple sensing signal resources, signals can be transmitted simultaneously using multiple beams at each time, wherein the beam indication method for each port signal or each signal resource is the same as the scheme given in this embodiment.

[0561] Example 3:

[0562] In this embodiment, different sensing signals can be configured for indication. Different sensing signal resources are associated with different beams in the sensing signal configuration information. The beam scanning process is realized by configuring multiple sensing signal resources, as shown in Figures 11 and 12.

[0563] The second device sends multiple sensing signal configuration information to the first device. This sensing signal configuration information includes beam information associated with the sensing signals. The multiple sensing signals correspond to multiple beams in different directions; that is, the multiple sensing signals are transmitted using different spatial filters and are associated with a specific receiving beam. The sensing signals are the sensing signals themselves, and the sensing signal configuration information is associated with sensing requirements, including:

[0564] N sensing signals correspond to N transmitting beams in different directions (and / or M receiving beams in different directions). The N beam directions (and / or M beam directions) are associated with the sensing angle range (Field of View, FoV): FoV can be related to device capabilities, the area to be sensed, or the distribution of the sensed targets.

[0565] Each sensed signal's time-domain resource contains one or more (>=2) time units (e.g., multiple OFDM symbols, which can be continuous or discontinuous). When multiple time units are included:

[0566] The duration of each sensed signal in the time domain or the duration occupied by multiple time units is greater than or equal to the coherent processing duration, the definition of which is the same as in Example 1.

[0567] In multiple time units, the time interval between two adjacent time units, wherein the time domain interval ΔT (Note: Here ΔT refers to the time domain resource interval of the same signal (transmitted using the same beam) in Figure 11 or Figure 12) satisfies the Doppler / velocity unambiguous measurement requirements, and the frequency domain interval Δf satisfies the time delay / distance unambiguous measurement requirements.

[0568] For example, for monostatic sensing:

[0569] If the direction of velocity is considered, the time interval satisfies ΔT≤1 / (2|f) dmax |) or If we disregard the fact that the velocity direction and time interval satisfy ΔT≤1 / f dmax or Where f dmax For the maximum unambiguous Doppler, v max For the maximum unambiguous velocity, f c denoted as carrier frequency, and c as the speed of light.

[0570] For bistatic sensing:

[0571] If the direction of velocity is considered, the time interval satisfies ΔT≤1 / (2|f) dmax |) or If we disregard the fact that the velocity direction and time interval satisfy ΔT≤1 / f dmax or β is the bibase angle.

[0572] Each sensed signal's frequency domain resource contains one or more (>=2) frequency elements (e.g., multiple subcarriers, which can be continuous or discontinuous), and satisfies:

[0573] The frequency domain bandwidth corresponding to each sensing signal is B≥c / (2ΔR), where B is the frequency domain bandwidth, c is the speed of light, and ΔR is the distance resolution.

[0574] Frequency domain resource spacing satisfies Δf≤1 / τ max Or Δf≤c / (2R) max ), where τ max For the maximum unambiguous delay, v max The maximum unambiguous distance.

[0575] The beam type associated with a signal can be indicated by the signal purpose field in the signal configuration information or by adding a signal type field.

[0576] Before the second device sends the sensing signal configuration information to the first device, it further includes acquiring the first device's capability information, sensing requirement information, or prior information about the sensing target. The second device determines the sensing signal configuration information based on the first device's capability information, sensing requirement information, or prior information about the sensing target.

[0577] The first device receives and measures a sensing signal according to the sensing signal configuration information to obtain a measurement result; or, the first device sends a sensing signal, receives the sensing signal echo, and measures according to the sensing signal configuration information to obtain a measurement result. The measurement result includes at least one of the following:

They can be transmitted with the same signaling or with different signaling, and this embodiment does not impose any restrictions.

[0584] This application provides several different methods for beam indication, including one-time indication of the associated transmit beam and / or receive beam used by the receiving device for the configured sensing signal, as well as beam scanning or switching methods. These methods eliminate the need for real-time beam switching indication, saving signaling overhead. Based on the characteristics of the sensing service, a dynamic beam scanning or switching method for the sensing signal can be used, allowing for more flexible real-time beam adjustment during measurement. In scenarios involving target tracking and sensing, considering target mobility, dynamic beam indication ensures sensing performance, enables on-demand configuration, and saves resources. Furthermore, beam indication can be achieved by configuring different sensing signals, i.e., associating different sensing signals with different beams in the sensing signal configuration information. By allocating time-domain resources for multiple sensing signals, a beam scanning process that meets the needs of the sensing service can be implemented.
