[0027] In order to better understand the perception method disclosed in the embodiments of the present application, the communication system to which the embodiments of the present application are applicable will be described first.

Those skilled in the art can know that, with the evolution of system architecture and the appearance of new business scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.
[0037] Please refer to Figure 2 , a flowchart of a perceiving method provided by the embodiments of the present application is shown as follows, Figure 2 The perceiving method can include but is not limited to the following steps:
[0038] S201, the terminal device performs beam scanning on the first carrier to obtain a first perceiving result of the perceiving object.
[0039] In the case of needing to perceive the perceiving object, the terminal device can perform beam scanning on the first carrier to obtain a first perceiving result of the perceiving object.
[0040] The terminal device performs beam scanning on the first carrier means that the terminal device scans all beams on the first carrier in turn. The terminal device performs beam scanning on the first carrier can also be described as that the terminal device performs beam polling on the first carrier.
[0041] Optionally, S201 in a specific implementation includes: the terminal device performs periodic beam sweeping on the first carrier. At this time, the time-frequency resource used for beam sweeping can be periodic or semi-persistent. Wherein, the time-frequency resource used for beam sweeping is semi-persistent, which means that the time-frequency resource used for beam sweeping can be activated by one downlink control information (DCI) and deactivated by another DCI, and within the activated time period, the time-frequency resource used for beam sweeping is periodic. Optionally, the terminal device can receive radio resource control (RRC) signaling from the network device, which can be used to configure the time-frequency resource used for beam sweeping.
[0042] S202, the terminal device performs beam sweeping on the first carrier to obtain a second sensing result of the sensing object; wherein the first beam is determined according to the first sensing result.
[0043] After the terminal device obtains the first sensing result, it can further perform sensing measurement on the sensing object to improve the accuracy of the sensing result. Specifically, the terminal device can perform beam sweeping on the first beam on the second carrier to further perform sensing measurement on the sensing object. Wherein, performing beam sweeping on the first beam can mean: further sweeping for one beam on the first carrier. S201 performs coarse-grained beam sweeping, and S202 performs fine-grained beam sweeping, which can improve the accuracy of the sensing result.
[0044] Wherein, the first beam can indicate the direction that needs to be further sensed with higher accuracy according to the first sensing result. In one possible implementation, the first beam is determined by the network device, which can indicate the first beam to the terminal device so that the terminal device performs beam sweeping on the first beam on the second carrier. The specific implementation of this way can be referred to Figure 2 the description in the corresponding embodiment. In another possible implementation, the first beam can be determined by the terminal device. Specifically, the terminal device can determine whether higher accuracy sensing is needed according to the first sensing result, if needed, determine the first beam and perform S202; if not, it can send the first sensing result to the network device.
[0045] It should be noted that the higher-precision perception is performed in S202 in terms of the precision of the first perception result obtained in S201. It can be understood that the first beam is within the coverage of a beam scanned in the process of beam scanning in S201. For example, the beam scanning in S201 includes sequentially scanning beams 1, 2, …, 8 to obtain the first perception result. If it is determined according to the first perception result that higher-precision perception is needed, the first beam can be within the coverage of one of the eight beams. Alternatively, the number of first beams can be one or more. If the number of first beams is more than one, the first beams can be within the coverage of a beam scanned in the process of beam scanning in S201, or some of the first beams are within the coverage of a beam scanned in the process of beam scanning, and the other first beams are within the coverage of another beam scanned in the process of beam scanning. For example, the beam scanning in S201 includes sequentially scanning beams 1, 2, …, 8, and the first beams include beams a, b, and c. The beams a and b can be within the coverage of beam 1, and the beam c can be within the coverage of beam 2.
[0046] In an implementation manner, the higher-precision perception can be achieved by the following manner: the first carrier is a low-frequency carrier, and the second carrier is a high-frequency carrier. The advantage of using a low-frequency carrier for perception is wide beam coverage, and the advantage of using a high-frequency carrier for perception is fine beam and wide frequency band, and a high-resolution perception result can be obtained. Therefore, the higher-precision perception result can be obtained by performing S202.
[0047] It should be further noted that the low-frequency carrier and the high-frequency carrier are relative concepts. The high-frequency carrier refers to a carrier with a higher frequency relative to the low-frequency carrier, and the low-frequency carrier refers to a carrier with a lower frequency relative to the high-frequency carrier. The first carrier being a low-frequency carrier and the second carrier being a high-frequency carrier can also be described as: the frequency of the second carrier is higher than the frequency of the first carrier. For example, if 6 GHz is used as the judgment standard of high and low frequency carriers, a carrier with a frequency lower than 6 GHz can be referred to as a low-frequency carrier, and a carrier with a frequency higher than or equal to 6 GHz can be referred to as a high-frequency carrier.
[0048] Optionally, the scanned beam in the beam scanning process can be a wide beam, and the first beam can be a narrow beam (also referred to as a fine beam). It should be noted that the wide beam and the narrow beam are relative concepts. In relation to the wide beam, the narrow beam refers to a beam with a smaller main lobe width (or angle). In relation to the narrow beam, the wide beam refers to a beam with a larger main lobe width (or angle). The description that the scanned beam in the beam scanning process is a wide beam, and the first beam is a narrow beam can also be described as: the main lobe width (or angle) of the scanned beam in the beam scanning process is greater than the main lobe width (or angle) of the first beam.
[0049] S203, the terminal device sends a target sensing result of the sensing object to the network device; the target sensing result includes the first sensing result and the second sensing result, or the target sensing result is determined according to the first sensing result and the second sensing result. Correspondingly, the network device receives the target sensing result.
[0050] In the case where the target sensing result includes the first sensing result and the second sensing result, the terminal device can send the first sensing result and the second sensing result through the same message, or can send the first sensing result and the second sensing result through different messages. For example, the first sensing result is sent through message 1, and the second sensing result is sent through message 2. If the first sensing result and the second sensing result are sent through different messages, the present embodiment does not limit the execution order of sending the first sensing result and sending the second sensing result in step S202. For example, the terminal device can send the first sensing result to the network device before S202, or can send the first sensing result to the network device after S202, or can send the first sensing result to the network device before sending the second sensing result, or can send the first sensing result and the second sensing result to the network device at the same time.
[0051] After obtaining the first sensing result, if the terminal device determines that higher-precision sensing is needed according to the first sensing result, at this time, the target sensing result can be determined according to the first sensing result and the second sensing result. For example, the first sensing result is modified or added according to the second sensing result to obtain the target sensing result.
[0052] In an implementation manner, the network device can pre-configure some configured grant (CG) resources for the terminal device, and the terminal device can perform sensing on the CG resources. The CG resources can include resources used by the terminal device for higher-precision sensing (i.e., S202), such as a second carrier. The CG resources can also include resources used by the terminal device for low-precision sensing (i.e., S201), such as a first carrier. In an implementation manner, the resources used by the terminal device for higher-precision sensing (i.e., S202) can be periodic or semi-persistent.
[0053] In an implementation manner, the network device can send configuration information to the terminal device to configure the terminal device with the resource used for sensing. The configuration information can explicitly carry the resource used for sensing, or the configuration information can implicitly carry the resource used for sensing. Explicitly carrying means that the configuration information includes an identifier of the resource used for sensing, and implicitly carrying means that the configuration information includes information having a corresponding relationship with the resource used for sensing, and the terminal device can determine the resource used for sensing through the information and the corresponding relationship.
[0054] Optionally, the resource used for sensing can be used only for sensing. For example, the network device separately configures some carriers for sensing. Alternatively, the resource used for sensing can be used not only for sensing but also for communication. For example, the network device configures a component carrier (CC) that can be used for both sensing and communication for the terminal device through an explicit or implicit manner. Optionally, the first carrier and the second carrier can both belong to the CC that can be used for both sensing and communication.
[0055] By implementing the embodiments of the present application, in the case that the first sensing result is obtained, the first beam is determined according to the first sensing result, and then the terminal device performs beam scanning on the first beam on the second carrier to obtain the second sensing result. In this way, more information related to the sensing object can be obtained, thereby facilitating improvement of the accuracy of the sensing result.
[0056] Please refer to Figure 3 , Figure 3 is a flowchart of another sensing method provided by the embodiments of the present application, as shown in Figure 3 , the sensing method can include but is not limited to the following steps:
[0057] S301, the terminal device performs beam scanning on a first carrier to obtain a first sensing result of a sensing object.
[0058] It should be noted that the execution process of step S301 can refer to the specific description of step S201 in the corresponding embodiment, which will not be described here again. Figure 2
[0059] S302, the terminal device sends the first sensing result to the network device. Correspondingly, the network device receives the first sensing result.
[0060] The terminal device sends the first sensing result to the network device, so that the network device determines whether higher-precision sensing is needed according to the first sensing result.
[0061] S303. Based on the first sensing result, the network device sends a first instruction information to the terminal device, which instructs the terminal device to perform beam scanning on the second carrier. Accordingly, the terminal device receives the first instruction information.
[0062] If the network device determines, based on the first sensing result, that higher precision sensing is required, it can generate first indication information and send the first indication information to the terminal device to instruct the terminal device to perform beam scanning on the second carrier to complete higher precision sensing.
[0063] In one implementation, the first indication information may include, but is not limited to, at least one of the following: second indication information for indicating a target historical reference signal, wherein the first beam is determined based on the beam corresponding to the target historical reference signal, and the second carrier is determined based on the carrier corresponding to the target historical reference signal; the direction of the first beam; the number of the first beams; the index of the second carrier; and information for indicating the second beam, wherein the first beam is determined based on the second beam, and the beam scanned by the terminal device during beam scanning on the first carrier includes the second beam.
[0064] In cases where higher-precision sensing is required, the network device can determine the beam direction for which higher-precision sensing is needed. In this case, the first indication information may include the direction of the first beam. For example, the network device may indicate that higher-precision sensing is achieved using two first beams: a 40-degree beam and a 60-degree beam. Alternatively, the first indication information may include information indicating a second beam. After receiving the first indication information, the terminal device can determine the first beam based on the second beam, and the first beam is within the coverage area of the first beam. The beam scanned by the terminal device during beam scanning on the first carrier includes this second beam. If the beam scanning refers to a wide-beam scan, then the second beam is a wide-beam. Optionally, the first beam can be determined based on the second beam by identifying N first beams, and these N first beams are within the coverage area of the second beam. Here, N can be a preset integer greater than or equal to 1. For example, if the second beam is an 80-degree beam and N=3, the determined first beam can include: a 20-degree beam, a 40-degree beam, and a 60-degree beam. Optionally, N can be agreed upon by the protocol or can be set or modified by the terminal device by default.
[0065] If it is determined that higher precision sensing is required, the network device can also determine the number of first beams that need to be sensed with higher precision; in other words, the aforementioned N can be indicated by the network device.
[0066] The second indication information is used to indicate a target historical reference signal. The historical reference signal can refer to a reference signal transmitted between the terminal device and the network device before step S303. The historical reference signal can include a reference signal transmitted by the terminal device to the network device, or a reference signal transmitted by the network device to the terminal device. Optionally, the second indication information can include an index of a target corresponding relationship in the corresponding relationship (between a historical reference signal transmitted by a wide beam and a historical reference signal transmitted by a narrow beam), and the target historical reference signal includes a historical reference signal transmitted by a narrow beam in the target corresponding relationship. For example, the corresponding relationship can be as shown in Table 1.
[0067] Table 1: Corresponding relationship
[0068]
[0069] Referring to Table 1, if the second indication information is index-2, it indicates that the target corresponding relationship is the second corresponding relationship in Table 1. In this case, the target historical reference signal includes historical reference signal 2, historical reference signal 3, and historical reference signal 4.
[0070] As can be seen from Table 1, in the corresponding relationship, a historical reference signal transmitted by a wide beam can correspond to one or more historical reference signals transmitted by a narrow beam. One historical reference signal transmitted by a wide beam can have multiple corresponding relationships, and the corresponding historical reference signals transmitted by a narrow beam are different in different corresponding relationships. For example, in Table 1, historical reference signal 1 corresponds to two corresponding relationships. In the first corresponding relationship, historical reference signal 1 corresponds to historical reference signal 2. In the second corresponding relationship, historical reference signal 1 corresponds to historical reference signal 2, historical reference signal 3, and historical reference signal 4.
[0071] Optionally, the network device can send third indication information to the terminal device, and the third indication information is used to indicate the corresponding relationship (between a historical reference signal transmitted by a wide beam and a historical reference signal transmitted by a narrow beam). Correspondingly, the terminal device can receive the third indication information from the network device, so as to obtain the corresponding relationship. Optionally, the third indication information can be carried in RRC signaling, or the third indication information is RRC signaling.
[0072] The network device indicates the target historical reference signal to the terminal device, and specifically indicates the terminal device to perform beam scanning with reference to the target historical reference signal. Specifically, the terminal device performs beam scanning according to a beam corresponding to the target historical reference signal and a carrier corresponding to the target historical reference signal. For example, the terminal device performs beam scanning using the beam corresponding to the target historical reference signal and the carrier corresponding to the target historical reference signal. If the target historical reference signal is a reference signal previously transmitted by the terminal device to the network device, the beam corresponding to the target historical reference signal can be a transmission beam used by the terminal device when the target historical reference signal is transmitted, and the carrier corresponding to the target historical reference signal can be a carrier used by the terminal device when the target historical reference signal is transmitted. If the target historical reference signal is a reference signal previously received by the terminal device from the network device, the beam corresponding to the target historical reference signal can be a reception beam used by the terminal device when the target historical reference signal is received, and the carrier corresponding to the target historical reference signal can be a carrier used by the terminal device when the target historical reference signal is received.
[0073] Optionally, the first indication information can be carried in the DCI, or the first indication information is the DCI. Optionally, the carrier carrying the first indication information can belong to the same carrier unit as the second carrier, or the carrier carrying the first indication information can not belong to the same carrier unit as the second carrier, which is a cross-carrier scheduling case.
[0074] S304, the terminal device performs beam scanning on the first beam on the second carrier according to the first indication information to obtain a second sensing result of the sensing object; wherein the first beam is determined according to the first sensing result.
[0075] In the case that the first indication information includes second indication information for indicating the target historical reference signal, the terminal device can perform beam scanning with reference to the target historical reference signal after learning the target historical reference signal. Specifically, the terminal device can perform beam scanning with reference to the target historical reference signal in the following manner: the terminal device determines a first beam according to a beam corresponding to the target historical reference signal, and determines a second carrier according to a carrier corresponding to the target historical reference signal, and performs beam scanning on the first beam on the second carrier. Optionally, the first beam can be the beam corresponding to the target historical reference signal, and the second carrier can be the carrier corresponding to the target historical reference signal.
[0076] It should be noted that the remaining execution process of step S304 can be referred to Figure 2 The specific description in step S202 in the corresponding embodiment will not be repeated here.
[0077] S305. The terminal device sends the second sensing result of the sensing object to the network device. Correspondingly, the network device receives the second sensing result.
[0078] By implementing the embodiments of the present application, the network device sends first indication information to the terminal device according to the first sensing result, so that the terminal device performs beam sweeping on the first beam on the second carrier according to the first indication information to obtain the second sensing result. In this way, more information related to the sensing object can be obtained, thereby facilitating improvement of the accuracy of the sensing result.
[0079] Please refer to Figure 4 , Figure 4 is a structural schematic diagram of a sensing device provided by the embodiments of the present application. As Figure 4 indicated, the sensing device 40 includes a beam sweeping unit 401 and a sending unit 402. Wherein,
[0080] The beam sweeping unit 401 is configured to perform beam sweeping on a first carrier to obtain a first sensing result of a sensing object.
