[0135] As shown in Figure 1a, the communication system 100 includes a sensing receiving device 101, a sensing transmitting device 102, a sensing target 103, and a sensing management node 104. The communication system 100 is an ISAC system.

[0136] In some embodiments, the sensing receiving device 101 may also be referred to as a receiving end, which may be a terminal or an access network device.

[0137] Optionally, the terminal may include, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

[0138] Optionally, the access network device may be a node or device that connects a terminal to a wireless network. The access network device may include, but is not limited to, at least one of the following in a 5G communication system: base station, evolved NodeB (eNB), next generation eNB (ng-eNB), next generation NodeB (gNB), node B (NB), home node B (HNB), home evolved nodeB (HeNB), radio backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a wireless fidelity (WiFi) system.

[0139] The access network equipment can be composed of a central unit (CU) and a distributed unit (DU). The CU can also be called a control unit. The CU-DU structure can separate the protocol layer of the access network equipment. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU, which is centrally controlled by the CU. However, this is not the only option.

[0140] In some embodiments, the sensing and transmitting device 102 may also be referred to as a transmitting end, which may be a terminal or an access network device.

[0141] In some embodiments, the sensing target 103 may be referred to as a reflector or target object, which may be a moving object or device in the environment.

[0142] In some embodiments, the name of the sensing management node 104 is for illustrative purposes only, and may also be referred to as a sensing node, sensing function node, sensing processing node, sensing management function (SMF) or sensing function control (SF-C) node, etc. The sensing management node 104 may be a network element or functional entity in the core network equipment, or it may be a separate node or device; this disclosure does not limit this.

[0144] In some embodiments, within the ISAC system, the sensing transmitting device 102 acts as a wireless signal transmitter, capable of transmitting radio waves or sensing reference signals (or sensing signals). The sensing receiving device 101 acts as a wireless signal receiver, capable of receiving radio waves or sensing reference signals. During the transmission of the sensing reference signal, its transmission may be blocked by objects (such as the sensing target 103), resulting in wireless transmission effects such as reflection, diffraction, transmission, phase change, Doppler shift, and signal strength variation. The sensing receiving device 101 receives the sensing reference signal, compares the transmitted and received signals, or records historical changes in the received signal, and reports this information to the sensing management node 104. The sensing receiving device 101 or the sensing management node 104 then determines the relevant information of the sensing target 103.

[0145] In some embodiments, the sensing receiving device 101 and the sensing transmitting device 102 may be the same device or different devices.

[0146] In some embodiments, the sensing mode can be divided into two types based on whether the sensing receiving device 101 and the sensing transmitting device 102 are the same device: as shown in FIG1b, the first type is mono-static sensing, that is, the sensing receiving device 101 and the sensing transmitting device 102 are the same device; as shown in FIG1c, the second type is bi-static sensing, that is, the sensing receiving device 101 and the sensing transmitting device 102 are not the same device.

[0148] Mode (1): Base station transmits and receives signals, such as base station A transmitting wireless signals or radio waves and base station A receiving wireless signals.

[0149] Mode (2): Base station A sends and base station B receives. For example, base station A sends a wireless signal and base station B receives the wireless signal.

[0150] Mode (3): Base station sends, terminal receives. For example, base station A sends a wireless signal, and terminal A receives the wireless signal.

[0151] Mode (4): Terminal sends, base station receives. For example, terminal A sends a wireless signal and base station A receives the wireless signal.

[0152] Mode (5): Terminals send and receive signals independently, such as terminal A sending wireless signals and terminal A receiving wireless signals.

[0153] Mode (6): Terminal A sends and Terminal B receives. For example, Terminal A sends a wireless signal and Terminal B receives the wireless signal.

[0160] In communication systems that do not involve ISAC, beam management typically uses Layer 1 Reference Signal Received Power (L1-RSRP) or Layer 1 Signal to Interference plus Noise Ratio (L1-SINR) as the measurement for beam management.

[0161] However, in ISAC communication systems involving sensing services, the maximum RSRP of a beam pair can only guarantee the maximum energy of the sensing signal received by the sensing receiver, but it cannot determine whether the sensing signal is aligned with or passes through the sensing target. For example, as shown in Figure 1d, based on measurements such as RSRP, beam pair 2-B theoretically has the highest RSRP, but its path is very likely not to pass through the sensing target; while beam pair 1-A, although its RSRP value is lower than the highest RSRP, its path will pass through the sensing target. Therefore, using beam pair 1-A in ISAC will bring sensing performance gains. Therefore, to accurately sense the sensing target, a new reporting method is needed in the ISAC communication system to report new sensing beam management measurements or reported quantities.

[0162] Figure 2a is an interactive schematic diagram illustrating a method for sending and receiving indication information according to an embodiment of the present disclosure. As shown in Figure 2a, the present disclosure relates to a method for sending and receiving indication information, the method comprising:

[0163] In step S2101, the sensing transmitting device 102 sends a first reference signal to the sensing receiving device 101.

[0164] In some embodiments, the sensing transmitting device 102 may be a terminal or an access network device, and the sensing receiving device 101 may be a terminal or an access network device. In the description of the embodiments of this disclosure, the sensing transmitting device 102 is taken as an access network device such as a base station (BS), and the sensing receiving device 101 is taken as a terminal.

[0165] In some embodiments, the first reference signal may be a Synchronization Signal Physical Broadcast Channel Block (SSB).

[0166] In some embodiments, the sensing receiving device 101, such as a terminal, may initiate an initial access or random access to the sensing transmitting device 102, such as a BS. During the initial access or random access process, the sensing transmitting device 102 may transmit a first reference signal.

[0167] In this embodiment, there may be multiple transmission paths (hereinafter referred to as paths in this embodiment) between the sensing receiving device 101 and the sensing transmitting device 102. The sensing transmitting device 102 may transmit the first reference signal on different paths, and the sensing receiving device 101 may receive the signal on the corresponding path.

[0168] For example, referring to Figure 2b, in a Multiple-Input Multiple-Output (MIMO) system, the sensing transmitting device 102 may have multiple transmitting beams, and the sensing receiving device 101 may have multiple receiving beams. To distinguish it from the description of the following embodiments, the transmitting beam in Figure 2b is a wide beam, i.e., a wide transmitting beam, and the receiving beam is a wide beam, i.e., a wide receiving beam.

[0169] In one example, the sensing transmitting device 102 has M wide transmitting beams and the sensing receiving device 101 has N wide receiving beams, as shown in Figure 2b, where M=4 and N=3. The M wide transmitting beams are beam 1, beam 2, beam 3 and beam 4, and the N wide receiving beams are beam A, beam B and beam C.

[0170] In this example, during the initial connection or random access process of the sensing receiving device 101, the sensing transmitting device 102 can use M wide transmission beams to transmit M first reference signals (such as SSBs), or transmit one first reference signal on one wide transmission beam. The sensing receiving device 101 uses N wide beams to receive the aforementioned first reference signals.

[0171] It is worth noting that the terms "first" and "second" in the first reference signal or the second reference signal involved in the following steps are used to distinguish the reference signals transmitted by the sensing and transmitting device 102 in different steps or at different times, rather than to limit the type or transmission parameters of the reference signal.

[0172] In step S2102, the sensing and receiving device 101 identifies the initial target in the environment based on the measurement result of the first reference signal.

[0173] In some embodiments, as shown in FIG2b, a wide transmit beam and a wide receive beam can form M*N beam pairs. A first reference signal can be transmitted along the path of each beam pair, such as along the path of beam pair 2-B. The sensing and receiving device 101 identifies an initial target in the environment based on the measurement results of the first reference signal along the path of one or more of the M*N beam pairs.

[0174] In some embodiments, the initial target may be an object or device that is stationary in the environment or does not move for a certain period of time.

[0175] Optionally, the sensing and receiving device 101 directly receives the first reference signal. The first reference signal received after being reflected or scattered by the initial target will have characteristics such as reflection, diffraction, transmission, phase change, Doppler shift, and signal intensity change. Therefore, the sensing and receiving device 101 can identify the initial target.

[0176] Optionally, the measurement result of the sensing and receiving device 101 on the first reference signal can be a signal metric value determined based on changes during signal transmission, such as signal energy or signal power. The sensing and receiving device 101 can determine the signal energy by obtaining the peak value of the fuzzy function image based on algorithms such as two-dimensional discrete Fourier transform (2D-DFT); or by obtaining the estimated spectral peak energy based on a spectral estimation algorithm.

[0177] Optionally, the sensing and receiving device 101 can identify the initial target based on the measurement results along different paths using a sensing algorithm. For example, the sensing and receiving device 101 generates a radar image based on 2D-DFT. Referring to Figure 2c, three initial targets are identified, where the horizontal axis represents velocity and the vertical axis represents range.

[0178] In some embodiments, after the sensing receiving device 101 identifies the initial target, it can also identify the target in a timely manner when the target is present.

[0179] In step S2103, the sensing receiving device 101 determines the sensing target 103 in the environment.

[0180] In some embodiments, the sensing transmitting device 102 may transmit a first reference signal over a certain period of time, and the sensing receiving device 101 may continuously receive the first reference signal; or, after transmitting the first reference signal, the sensing transmitting device 102 may transmit a new reference signal again. For example, the sensing transmitting device 102 may use M wide transmitting beams to transmit M SSBs respectively, and the sensing receiving device 101 may use N relatively wide beams to receive the SSBs respectively.

[0181] Optionally, the first reference signal or the new reference signal may be transmitted periodically, aperiodically, or semi-continuously.

[0182] Optionally, in the first reference signal or the new reference signal, the reference signal on each path can be associated with a different reference signal identifier (ID).

[0183] In some embodiments, the sensing receiving device 101 generates a new radar image (as shown in Figure 2d) based on the measurement results on different paths, such as the measurement results on the paths of one or more beam pairs in M*N beam pairs, according to a sensing algorithm (e.g., 2D-DFT), and identifies newly appearing targets outside the initial target.

[0184] Optionally, in this step, the sensing receiving device 101 identifies or determines the sensing target 103 based on a coarse beam scan. Here, the coarse beam scan can refer to the process of identifying the target based on a wide transmit beam and a wide receive beam.

[0185] In some embodiments, the sensing receiving device 101 can determine whether a newly appearing target is a sensing target 103. Referring to FIG. 1d, the sensing target 103 can be a moving object or device, such as a moving person.

[0186] In one example, when a new target appears, the sensing receiving device 101 can determine whether a sensing target exists based on the result of two calculations. For example, the sensing receiving device 101 determines whether a sensing target 103 has appeared based on the new radar image in Figure 2d and the initial radar image in Figure 2c.

[0187] In this example, if a signal metric value greater than a threshold exists on the path of a beam pair, it is determined that a sensing target 103 exists on the path of that beam pair. For example, the signal metric value can be a signal energy value determined by an algorithm, or other signal parameters. Referring to the example in Figure 2d, in the new radar image of Figure 2d, if the signal energy corresponding to a newly appearing target is greater than the threshold, and a peak with energy greater than the threshold appears in the radar image, it is determined that sensing target 103 has appeared, that is, the newly appearing target is sensing target 103; otherwise, it is determined that no sensing target 103 has appeared.

[0188] In this example, the threshold can be predefined by the protocol or configured by the network device. The network device can include at least one of an access network device or a core network device.

[0189] In this example, if the sensing receiving device 101 identifies or determines the sensing target 103, the following steps can be performed. If the sensing receiving device 101 does not identify or determine the sensing target 103, measurement can continue according to business needs.

[0190] In some embodiments, the sensing receiving device 101 can determine the path of the sensed target 103 based on measurements, i.e., on which beam pair the target is located. For example, suppose that in the example corresponding to Figure 2d, the sensed target 103 is on the path of beam pair 2-B.

[0191] Optionally, a sensing target 103 may exist on multiple paths between the sensing receiving device 101 and the sensing transmitting device 102, i.e., on multiple beam pairs. The sensing targets on different paths may be the same or different. When the same sensing target 103 appears on different paths, the signal energy of the sensing target measured on different paths will be different.

[0192] Optionally, for one or more paths where the sensing target 103 exists, the beam pairs corresponding to these paths can be considered the optimal beam pairs. Alternatively, for one or more paths where the sensing target 103 exists, and the signal energy of the sensing target 103 is greater than a certain threshold, the beam pairs corresponding to these paths can be considered the optimal beam pairs. Alternatively, for one or more paths where the sensing target exists, if there is a path with the strongest signal energy of the sensing target 103, the beam pairs corresponding to that path are considered the optimal beam pairs.

[0193] In step S2104, the sensing receiving device 101 determines the wide beam pair associated with the sensing target.

[0194] In some embodiments, the sensing receiving device 101 determines K wide beam pairs among the M*N wide beam pairs that are associated with the sensing target based on the measurement results of the reference signals corresponding to the M*N wide beam pairs. Here, M, N, and K are integers.

[0195] In some embodiments, the beam pairs associated with the sensing target, such as the optimal beam pairs, include wide beam pairs and / or narrow beam pairs. The narrow beam pairs include the optimal narrow beam pairs in the embodiments described below.

[0196] For example, as shown in Figure 1d or Figure 2b, the transmitting beam includes M wide transmitting beams, and the receiving beam includes N wide receiving beams, which can correspond to M*N wide beam pairs. Based on the measurement results on the path of each wide beam pair, the sensing receiving device 101 can determine the beam pair path where the sensing target is located, thereby determining the K paths or K wide beam pairs associated with the sensing target.

[0197] In the example corresponding to Figure 1d or Figure 2b, K=1, and the wide beam pair associated with the sensing target is beam pair 2-B, that is, the optimal beam pair includes beam pair 2-B.

[0198] In step S2105, the sensing receiving device 101 sends third indication information to the sensing sending device 102.

[0199] In some embodiments, the third indication is used to indicate: the reference signal identifiers corresponding to the K wide beam pairs, and / or the signal metric values ​​of the sensed targets on the path of the K wide beam pairs.

[0200] Optionally, based on the measurement results, the sensing and receiving device 101 can report the K reference signal IDs with the highest signal metric values ​​and the energy of the corresponding peaks.

[0201] For example, in the example corresponding to Figure 1d or Figure 2b, K=1, the sensing receiving device 101 can report the reference signal identifier corresponding to beam pair 2-B, and / or the signal metric value of the sensed target in the path of beam pair 2-B.

[0202] In some embodiments, the sensing transmitting device 102 receives the third indication information and can determine a wide beam pair associated with the sensing target.

[0203] In step S2106, the sensing transmitting device 102 sends a second reference signal to the sensing receiving device 101.

[0204] In some embodiments, the sensing transmitting device 102 determines a wide beam pair associated with the sensing target based on the third indication information reported by the sensing receiving device 101, and can then determine the optimal wide transmitting beam in the wide beam pair. For example, in the example corresponding to FIG1d or FIG2b, when K=1, the wide beam pair associated with the sensing target is beam pair 2-B, in which the wide transmitting beam is beam 2.

[0205] In some embodiments, the envelope of a wide beam may include multiple narrow beams, such as M1 narrow beams. Referring to Figure 2e, beam 2 includes 4 narrow beams, i.e., M1 = 4, which can be referred to as beam 21, beam 22, beam 23 and beam 24.

[0206] In some embodiments, after determining the optimal wide transmission beam, the sensing and transmitting device 102 can transmit the second reference signal on M1 narrow beams within the envelope of the wide transmission beam. For example, as shown in FIG2e, the sensing and transmitting device 102 transmits four second reference signals on four narrow beams within the envelope of beam 2.

[0207] Optionally, the second reference signal can be CSI-RS, SRS, or other newly defined sensing RS.

[0208] In some embodiments, the sensing receiving device 101 uses a wide receiving beam from a wide beam pair associated with the sensing target to receive the aforementioned second reference signal.

[0209] In this embodiment, the sensing receiving device 101 can use the wide receiving beam in one of the K wide beam pairs to receive the reference signal transmitted by the sensing transmitting device on the M1 narrow transmitting beams; for example, when K=1, as shown in FIG2e, the sensing transmitting device 102 transmits 4 second reference signals on the 4 narrow beams within the envelope of beam 2 respectively, and the sensing receiving device 101 uses the wide receiving beam (beam B) in beam pair 2-B to receive the second reference signal.

[0210] In step S2107, the sensing receiving device 101 determines the narrow beam pair associated with the sensing target.

[0211] In some embodiments, the sensing receiving device 101 determines K1 narrow beam pairs associated with the sensing target based on the measurement results of reference signals on M1 narrow transmit beams.

[0212] Where M1 and K1 are integers.

[0213] In some embodiments, the sensing receiving device 101 determines K1 narrow beam pairs associated with the sensing target among K wide beam pairs.

[0214] For example, referring to Figure 2e, the sensing and receiving device 101 can calculate the radar image shown in Figure 2f based on the measurement results of the second reference signal, and determine the K1 reference signal IDs and / or signal metric values ​​with the highest signal metric values ​​associated with the sensed target. Compared to Figure 2d, the sensed target in Figure 2f corresponds to a higher energy. In one example, K1 = 1, and the narrow beam pair associated with the sensed target determined based on the measurement is beam pair 23-B.

[0215] In step S2108, the sensing receiving device 101 sends the fourth indication information to the sensing sending device 102.

[0216] In some embodiments, the fourth indication information is used to indicate: the reference signal identifiers corresponding to the K1 narrow beam pairs, and / or the signal metric values ​​of the sensed targets on the path of the K1 narrow beam pairs.

[0217] Optionally, based on the measurement results, the sensing and receiving device 101 can report the K1 reference signal IDs with the highest signal metric values ​​and the energy of the corresponding peaks.

[0218] For example, in the example corresponding to Figure 2e, K1 = 1, the sensing receiving device 101 can report the reference signal identifier corresponding to beam pair 23-B, and / or the signal metric value of the sensed target in the path of beam pair 23-B.

[0219] In some embodiments, the sensing transmitting device 102 receives the fourth indication information and can determine the narrow beam pair associated with the sensing target.

[0220] In step S2109, the sensing transmitting device 102 sends a third reference signal to the sensing receiving device 101.

[0221] In some embodiments, the sensing transmitting device 102 determines a narrow beam pair associated with the sensing target based on the fourth indication information reported by the sensing receiving device 101, and can then determine the optimal narrow transmitting beam in the narrow beam pair. For example, in the example corresponding to FIG2e, when K1=1, the narrow beam pair associated with the sensing target is beam pair 23-B, in which the narrow transmitting beam is beam 23.

[0222] In some embodiments, after determining the optimal narrow transmission beam, the sensing and transmitting device 102 may repeatedly transmit the same reference signal, such as the third reference signal, N1 times on the narrow transmission beam.

[0223] Wherein, N1 depends on the number of narrow receiving beams within the envelope of the wide receiving beam in the optimal wide beam pair. For example, as shown in Figure 2g, the wide receiving beam B in beam pair 2-B includes 3 narrow receiving beams, i.e., N1 = 3.

[0224] In some embodiments, the sensing receiving device 101 uses a narrow receiving beam in an optimal wide receiving beam to receive a third reference signal, for example, using BA, BB and BC in beam B to receive the third reference signal.

[0225] In step S2110, the sensing receiving device 101 determines the optimal narrow beam pair associated with the sensing target.

[0226] In some embodiments, the sensing and receiving device 101 can calculate and obtain the radar image shown in FIG2h based on the measurement result of the third reference signal in step S2109, and determine the optimal narrow receiving beam among N1 narrow beams based on the signal metric value associated with the sensed target. For example, referring to the example in FIG2g, the optimal narrow receiving beam is beam BB.

[0227] In some embodiments, based on the above steps, the sensing and receiving device 101 can determine the wide beam pair in the optimal beam pair, such as beam pair 2-B; it can also further determine the narrow beam pair 23-B and the optimal narrow beam pair 23-BB in the optimal beam pair, thereby refining the beam pairs. Among them, beam pair 23-BB has the strongest sensing gain, and the energy of the radar image peak corresponding to the sensed target on the path of beam pair 23-BB will be significantly improved.

[0228] In this embodiment, the sensing receiving device 101 does not need to continue reporting the measurement to the sensing sending device 102.

[0229] In step S2111, the sensing receiving device 101 sends the first instruction information to the sensing management node 104.

[0230] In some embodiments, the perception management node may be, for example, an SMF. The perception association node receives the aforementioned first indication information.

[0231] In some embodiments, the first indication information is used to indicate the beam information of a beam pair associated with a sensing target.

[0232] Optionally, in step S2103, the sensing receiving device 101 can identify the sensing target, and the beam pair associated with the sensing target may include, for example, the beam pair corresponding to the path where the sensing target is located.

[0233] Optionally, the beam pair associated with the perceived target includes the optimal beam pair of the aforementioned embodiments. The beam pair associated with the perceived target, such as the optimal beam pair, may include the wide beam pair determined in step S2104, such as beam pair 2-B; it may also include the narrow beam pair determined in step S2107, such as beam pair 23-B; and it may also include the optimal narrow beam pair determined in step S2110, such as beam pair 23-BB. Alternatively, the optimal beam pair may include one or more of the wide beam pair, narrow beam pair, and optimal narrow beam pair. It is understood that the optimal narrow beam pair may be determined based on the narrow beam pair, and the narrow beam pair can be considered to include the optimal narrow beam pair.

[0234] Optionally, beam information can be used to indicate the beam pair associated with the sensed target, so that the sensed management node can know the beam pair or path corresponding to the sensed target. For example, the first indication information indicates the beam information of at least one of the following optimal beam pairs: wide beam pair, narrow beam pair, and optimal narrow beam pair.

[0235] In some embodiments, the beam pair includes the transmitting beam of the sensing transmitting device 102 and the receiving beam of the sensing receiving device.

[0236] In some embodiments, the beam information of the beam pair includes at least one of the following:

[0237] Path information for beam pairs;

[0238] The processing parameters of the beam for the corresponding signal or channel;

[0239] Reference signal identifier for the transmitted beam;

[0240] Spatial filtering information for the received beam.

[0241] Based on any one or more of the above beam information, the beam pair associated with the sensing target 103, such as the optimal beam pair, can be determined.

[0242] Optionally, the path information includes at least one of the following:

[0243] Path delay;

[0244] Doppler shift of the path;

[0245] The angle of the path.

[0246] Among them, one or more of the path information can uniquely determine a path, that is, determine the beam pair corresponding to the path.

[0247] The sensing management node 104 can process the path information reported by the sensing receiving device 101 to determine the information of the sensing target 103. For example, the sensing management node 104 can perform hard decision based on the path information to determine the location information of the sensing target.

[0248] Optionally, the processing parameters include at least one of the following:

[0249] The signal autocorrelation matrix corresponding to the beam pair;

[0250] The statistical autocorrelation matrix corresponding to the beam pair;

[0251] The channel autocorrelation matrix corresponding to the beam pair.

[0252] The statistical autocorrelation matrix can be either the signal statistical autocorrelation matrix or the channel statistical autocorrelation matrix.

[0253] The sensing management node 104 can determine the information of the sensing target 103 based on the processing parameters reported by the sensing receiving device 101. For example, the sensing management node 104 can perform soft decision based on the processing parameters to determine the location information of the sensing target.

[0254] In the above embodiments, hard decision and soft decision are used to indicate different computational processing methods of the perception management node 104, and are only for illustration. The computational processing method may depend on the implementation of the perception management node 104. Hard decision may involve processing different groups of processing parameters separately and averaging the processing results corresponding to different groups. Soft decision may involve uniformly processing and calculating different groups of processing parameters to obtain the processing result.

[0255] Optionally, in conjunction with the description of the foregoing embodiments, different reference signal identifiers (IDs) may be present on the paths of different beam pairs. Therefore, the sensing receiving device 101 can indicate the beam pair associated with the sensing target, such as the optimal beam pair, by reporting the reference signal ID.

[0256] The reference signal ID can be, for example, an SSB ID, a Channel-State-Information Reference Signal (CSI-RS) ID, a Sounding Reference Signal (SRS) ID, or a Sensing Reference Signal (SRS) ID.

[0257] Optionally, different beam pairs can correspond to different spatial reception filtering information, such as spatialRxInfro. The sensing and receiving device 101 can report the spatial reception filtering information corresponding to the beam pair associated with the sensing target, such as the optimal beam pair, thereby indicating the optimal beam pair.

[0258] In some embodiments, the sensing receiving device 101 reports the beam information of the beam pair associated with the sensing target, such as the optimal beam pair, to the sensing management node. For example, it reports the path information of one or more paths of the optimal transmit / receive beam pair, or reports the autocorrelation matrix or statistical autocorrelation matrix of the optimal beam pair.

[0259] In this embodiment, the perception management node 104 can perform calculations to determine the information of the perceived target, such as generating radar graphics or spectral estimation graphics using SMF to determine the information corresponding to the peak value of the perceived target.

[0260] In step S2112, the sensing receiving device 101 sends the second instruction information to the sensing management node 104.

[0261] In some embodiments, the second indication information is used to indicate the signal metric value corresponding to the sensing target on the path of the beam pair associated with the sensing target. For example, the second indication information is used to indicate the signal metric value corresponding to the sensing target on the path of the optimal beam pair.

[0262] In some embodiments, the first indication information and the second indication information can be sent through the same signaling, or the reporting order of the first indication information and the second indication information can be interchanged.

[0263] In some embodiments, the signal metric value corresponding to the sensing target may be determined by the sensing receiving device 101 based on measurement and algorithm processing.

[0264] For example, in conjunction with step S2103, the sensing receiving device 101 can extract the blur function corresponding to the sensing target based on the 2D-DFT algorithm and determine the peak energy of the image as the signal metric.

[0265] For example, the sensing and receiving device 101 can extract the estimated peak energy of the spectrum corresponding to the sensing target as a signal metric value based on spectrum estimation algorithms such as Multiple Signal Classification (MUSIC) and Estimation of Signal Parameters via Rotational Invariance Techniques (ESPRIT).

[0266] In some embodiments, optionally, the beam pair associated with the perceived target, such as the optimal beam pair, may include the wide beam pair determined in step S2104, such as beam pair 2-B; it may also include the narrow beam pair determined in step S2107, such as beam pair 23-B; and it may also include the optimal narrow beam pair determined in step S2110, such as beam pair 23-BB. Alternatively, the optimal beam pair may include one or more of the wide beam pair, the narrow beam pair, and the optimal narrow beam pair.

[0267] In this embodiment, the optimal beam pair including wide beam pairs is used as an example for illustration. It is assumed that the number of wide beam pairs associated with the sensing target can be K, where K is an integer.

[0268] In one example, when the beam pair associated with the perceived target is one, i.e., K=1, the second indication information includes an information field for indicating the signal metric value.

[0269] In this example, if there is one optimal beam pair, the second indication information may include an information field, which may include X bits, and these X bits are used to report the signal metric value corresponding to an optimal beam pair.

[0270] In another example, when there are multiple beam pairs associated with the perceived target, i.e., K > 1, the second indication information is used to indicate the signal metric value corresponding to the perceived target on the path of each beam pair.

[0271] In this embodiment, the second indication information includes a first information field and at least one second information field, and one first information field or one second information field corresponds to one beam pair; wherein, the first information field is used to indicate the maximum signal metric value, and the second information field is used to indicate the difference between the signal metric value of the target sensed on the beam pair corresponding to the second information field and the maximum signal metric value.

[0272] The first information field may include X bits, which are used to report the maximum signal metric value and can be associated with an optimal beam pair. At least one second information field may occupy Y bits, and each second information field is used to report the difference between the signal metric value corresponding to the associated optimal beam pair and the maximum signal metric value.

[0273] In this embodiment, the signal metric values ​​corresponding to different optimal beam pairs are reported in a differential manner.

[0274] In some embodiments, the number of beam pairs corresponding to the second indication information above, i.e., the number K of beam pairs associated with the sensing target, such as the optimal number of beam pairs, can be configured on the network side or predefined by the protocol.

[0275] For example, when configuring K on the network side, before step S2105, the method may further include: the network device sending configuration information to the sensing receiving device 101, the configuration information including the number K of beam pairs corresponding to the second indication information.

[0276] In some embodiments, the perception management node 104 receives the aforementioned second instruction information.

[0277] In step S2113, the perception management node 104 determines the location information of the perception target 103.

[0278] In some embodiments, the perception management node 104 determines the location information of the perception target 103 based on the first instruction information.

[0279] In some embodiments, the sensing management node 104 determines the location information of the sensing target 103 based on the first instruction information and the second instruction information.

[0280] In some embodiments, the location information may include the relative or absolute position of the sensing target 103. For example, the location information may include the coordinates, latitude and longitude of the sensing target 103. Alternatively, the location information may include the distance between the sensing target 103 and a known point. Alternatively, the location information may include the moving speed of the sensing target 103. Alternatively, the location information may include information such as the angle of the sensing target 103.

[0281] In some embodiments, the names of information, etc., are not limited to the names described in the embodiments. Terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", and "field" can be used interchangeably.

[0353] The embodiments disclosed herein aim to provide a new sensing beam management measurement quantity that is strongly correlated with the sensing target, i.e., the measurement quantity can accurately reflect whether the sensing signal has been backscattered by the sensing target.

[0354] In this embodiment of the disclosure, the sensing receiver explicitly reports the optimal transmit / receive beam pair to the sensing node, such as the Sensing Management Function (SMF) node:

[0355] Option 1: Report information about one or more paths of the optimal transmit / receive beam pair, such as time delay, Doppler, angle, etc. SMF can perform hard decision based on the reported information to determine the information of the sensed target.

[0356] Option Example 2: The autocorrelation matrix or statistical autocorrelation matrix of the optimal transmit / receive beam pair is reported. The SMF can make a soft decision based on the reported information to determine the information of the sensing target.

[0357] In this embodiment of the disclosure, the sensing receiver reports the energy of the newly identified sensing target associated with the optimal beam pair.

[0358] Optionally, the sensing receiver extracts the peak energy of the blurred function image corresponding to the newly identified sensing target based on the 2D-DFT algorithm.

[0359] Optionally, the sensing receiver extracts the estimated peak energy of the spectrum corresponding to the newly identified sensing target based on spectrum estimation algorithms such as MUSIC or ESPRIT.

[0360] The number K of the optimal beam pairs reported can be configured on the network side or predefined by the protocol.

[0361] When K=1, the absolute value of the energy is reported via the X bit.

[0362] When K>1, the absolute value of the maximum energy is reported via the X bits, and the difference values ​​of other energies are reported via the Y bits.

[0363] In this embodiment of the disclosure, the sensing receiver reports the reference signal ID corresponding to the optimal transmission beam, such as SSB / CSI-RS / SRS / Sensing RS ID.

[0364] In this embodiment of the disclosure, the sensing receiver reports the spatial receiving filtering information corresponding to the optimal receiving beam, such as spatialRxInfro.

[0365] To facilitate understanding of the embodiments of this disclosure, a specific example is given below. As shown in FIG6, the method of this example includes the following steps:

[0366] Step S6101, Initial identification of environmental targets P0.

[0367] As shown in Figures 2b to 2c, during the initial connection / random access of the UE, the BS uses M wide beams to transmit M reference signals (e.g., SSB), and the UE uses N wide beams to receive the above reference signals.

[0368] The UE generates radar images based on the measurement results of one or more pairs of beams in M*N beam pairs, and calculates them according to a perception algorithm (e.g., 2D-DFT) to perform preliminary identification of targets in the environment.

[0369] In this context, UE corresponds to the sensing receiving device in the aforementioned embodiments, and BS corresponds to the sensing transmitting device in the aforementioned embodiments.

[0370] Step S6102, coarse scanning of the sensing beam P1.

[0371] As shown in Figures 1d and 2d, the BS uses M wide beams to transmit M reference signals (e.g., SSB), each reference signal is associated with a different reference signal ID, and the UE uses N wide beams to receive the above reference signals.

[0372] The UE generates a new radar image based on the measurement results of one or more pairs of beams in M*N beam pairs, according to a sensing algorithm (e.g., 2D-DFT).

[0373] Optionally, the UE reports the information associated with the optimal beam pair to the sensing node, such as reporting information on one or more paths of the optimal transmit / receive beam pair, or reporting the autocorrelation array or statistical autocorrelation array of the optimal transmit / receive beam pair, so that the SMF can generate radar graphics or spectral estimation graphics or information corresponding to the peak value of the sensed target.

[0374] The UE determines whether a new target has appeared based on the new radar image and the initial environmental radar image. If a new peak with energy greater than a threshold appears in the radar image, it is determined that a new target has appeared; otherwise, it is determined that no target has appeared. The threshold can be predefined by the protocol or configured by the network.

[0375] If a new target is identified, proceed with the next step.

[0376] If no new sensing targets are identified, continue coarse scanning of the sensing beam (e.g., periodic, aperiodic, or semi-continuous) according to business needs.

[0377] After obtaining the energy of the new peak, the UE reports the K reference signal IDs with the highest energy and the corresponding peak energy to the BS.

[0378] Step S6103, Sensing and transmitting beam refinement P2.

[0379] As shown in Figures 2e and 2f, the BS determines the optimal transmission wide beam based on the information reported by the UE, and transmits M1 sensing reference signals (such as CSI-RS, SRS, or a newly defined sensing RS) through M1 narrow beams within the envelope of the wide beam. The UE uses the corresponding wide beam for reception.

[0380] The UE calculates and acquires the radar image based on each received signal, and reports the K1 reference signal IDs with the highest energy of the peak corresponding to the perceived target, along with the energy of the corresponding peak, to the BS.

[0381] Step S6104, Sensing and receiving beam refinement P3.

[0382] As shown in Figures 2g and 2h, the BS determines the optimal transmission narrow beam based on the information reported by the UE, and uses this beam to repeatedly transmit N1 identical sensing reference signals. The UE uses N1 narrow beams within the optimal wide beam for reception.

[0383] The UE calculates and obtains the radar image for each received signal, and determines the optimal receiving narrow beam based on the energy of the peak corresponding to the perceived target in the radar image, without having to report the measurement to the base station.

[0384] At this point, the narrow beam pair determination of the perceived target is completed (theoretically, the energy of the radar image peak corresponding to the perceived target is increased).

[0385] This disclosure proposes a sensing beam management scheme, which enables sensing beam scanning and measurement by reporting multipath information, autocorrelation array statistical characteristics, RS ID, spatial filtering information, etc.
