[0048] To help those skilled in the art better understand the technical solutions of the embodiments of the present disclosure, the technical solutions of the present disclosure will be clearly and completely described below in conjunction with the drawings in the present disclosure. Obviously, the embodiments described are only some of the embodiments of the present disclosure, not all of them. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0049] It should be noted that in this disclosure, words such as "exemplarily" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this disclosure as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplarily" or "for example" is intended to present the relevant concepts in a concrete manner.

[0050] Hereinafter, the terms "first," "second," and the like are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features being referred to. Thus, a feature designated as "first" or "second" may explicitly or implicitly include one or more of such features.

[0051] In the description of this disclosure, unless otherwise specified, " / " means "or." For example, A / B can mean A or B. "And / or" herein is merely a description of an association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: only A, only B, and both A and B. Furthermore, "at least one" means one or more, and "a plurality" means two or more.

[0052] The methods provided in the embodiments of the present disclosure can be applied to various communication systems. For example, the communication system can be a fifth-generation (5G) communication system, a Wi-Fi system, a 3GPP (3rd Generation Partnership Project)-related communication system, a future-evolved communication system (such as a sixth-generation (6G) communication system), or a system integrating multiple systems, and the embodiments of the present disclosure are not limited thereto.

[0053] The network architecture of the mobile communication network (including but not limited to 3G, 4G, 5G and future mobile communication networks) in the embodiment of the present disclosure may include at least a first node and a second node. In this example, the first node may be a network-side device (for example, including but not limited to a base station), and the second node may be a terminal-side device (for example, including but not limited to a terminal). In device-to-device communication between the two nodes, the first node and the second node may both be network-side devices or terminal-side devices. Of course, in some embodiments, the first node and the second node may also be communication nodes such as aircraft, drones, radar transmitting devices, etc., which are not limited in the present disclosure.

[0054] For example, taking the first node as a base station and the second node as a terminal, as shown in FIG1 , FIG1 illustrates a communication system provided by an embodiment of the present disclosure. The communication system includes a base station 110, a terminal 120, a sensing target 130, and a sensing function (SF) module 140. There can be one or more base stations 110 and terminals 120, and the number is not limited.

[0055] The base station 110 is configured to send a sensing signal to the sensing target 130 and receive an echo signal sent by the sensing target 130 in response to the sensing signal.

[0056] In some embodiments, the base station 110 may also be configured to perform collaborative sensing with the terminal 120 to jointly receive and process the echo signal of the sensing target 130. For example, the base station 110 may configure receiving resources for the terminal 120 and send indication information to the terminal 120, so that the terminal 120 assists the base station 110 in receiving the echo signal sent by the sensing target 130 based on the indication information.

[0057] In some embodiments, the base station can be a base station or an evolved base station (eNB or eNodeB) in long term evolution (LTE), long term evolution advanced (LTEA), a base station device in a 5G network, or a base station in a future communication system, etc. The base station can include various macro base stations, micro base stations, home base stations, wireless remote devices, reconfigurable intelligent surfaces (RISs), routers, relays, wireless fidelity (WI-FI) devices and other network side devices.

[0058] The terminal 120 is configured to, after receiving the indication information sent by the base station 110 , receive the echo signal on the receiving resource based on the perception detection mode indicated by the indication information, and report the measurement result of the echo signal to the base station 110 .

[0059] In some embodiments, the terminal may be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. The embodiments of the present disclosure do not limit the application scenarios. The terminal may also be sometimes referred to as a user, user equipment (UE), access terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal, mobile device, UE terminal, wireless communication device, UE agent or UE device, etc., which is not limited in the embodiments of the present disclosure.

[0060] SF module 140 is used to implement management functions such as selecting sensing nodes and controlling sensing services. In some embodiments, SF module 140 is communicatively connected to base station 110. As an example, SF module 140 can be integrated into base station 110 as part of base station 110. For example, SF module 140 can be a sensing module within base station 110. As another example, SF module 140 can exist independently of base station 110. For example, SF module 140 can be located within the core network.

[0061] It should be noted that the above scenarios are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Ordinary technicians in this field can know that with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0062] Cellular mobile systems possess powerful networking capabilities. Through large-scale deployment of cellular networks and the interaction between base stations and terminals, base stations and base stations, and base stations and core networks, a mobile network system with integrated communication and perception can be constructed. A perception network based on cellular mobile systems can fully utilize the base station resources of cellular mobile systems, reducing the cost of integrated communication and perception while also realizing the networking capabilities of communication and perception. By rationally selecting perception base stations within the cellular mobile system and sharing, supplementing, or merging perception data, the problem of signal interference caused by an excessive number of perception nodes can be reduced while retaining the advantages of cellular networks. Furthermore, through collaboration between base stations, the perception network can enhance perception of sensing targets and further improve perception performance without upgrading hardware.

[0063] In a narrow sense, a perception network refers to a system capable of target location (e.g., ranging, speed, and angle measurement), target imaging, target detection, and target identification. In a broad sense, a perception network refers to a system capable of perceiving the attributes and states of all services, networks, users, and terminals, as well as environmental objects. In a mobile network with integrated sensory perception, perception can be categorized into active and passive perception. Passive perception occurs when a perceiver (e.g., a network or terminal) acquires electromagnetic waves (e.g., terahertz waves) emitted by a perceived target or reflects electromagnetic waves from outside the perceiver and target. Active perception occurs when a perceiver (e.g., a network or terminal) transmits an electromagnetic wave (e.g., a perception signal) that, after being reflected by the perceived target, receives the echo signal for perception. The node receiving the echo signal is not necessarily the same node that sent the perception signal. In other words, multiple perceiver nodes can achieve active perception through some form of joint processing.

[0064] For example, in a sensing network, the links of sensing signals can be divided into the following categories: (1) Base station echo sensing link: the base station sends a sensing signal and receives an echo signal. (2) Inter-base station sensing link: base station 2 receives a sensing signal sent by base station 1. (3) Uplink sensing link: the base station receives a sensing signal sent by the UE. (4) Downlink sensing link: the UE receives a sensing signal sent by the base station. (5) Terminal echo sensing link: the UE sends a sensing signal and receives an echo signal. (6) Inter-terminal sensing link: UE2 receives a sensing signal sent by UE1. In actual implementation, different sensing links can be selected according to different sensing requirements. Each sensing link can have one or more sending nodes and receiving nodes, and the actual sensing system can include multiple different links.

[0065] However, since the position and state of the perception target are constantly changing, if a fixed node (for example, a base station) is always used to send a perception signal to the perception target during the movement of the perception target; or if a fixed perception detection mode (for example, a fixed perception link) is always used to perceive the perception target, it may cause perception failure within a certain period of time or interruption of the mobile position point of the perception target, thereby causing failure of perception detection of the perception target.

[0066] To address the above issues, see Figure 2, which is a flow chart of an information indication method provided by an embodiment of the present disclosure. As shown in Figure 2, the information indication method provided by an embodiment of the present disclosure is applied to a first node and includes the following S101.

[0067] S101. Send first information to a second node.

[0068] The first information is used to indicate the perception detection mode used by the second node.

[0069] It can be understood that based on the information indication method provided by the embodiment of the present disclosure, the first node (for example, a base station) sends a first information to the second node (for example, a terminal) to indicate the perception detection mode used by the second node, so that when the first node performs perception detection on the perception target, the second node can assist the first node in collaborative perception of the perception target, thereby reducing the perception burden of the first node. At the same time, since the position and state of the perception target are constantly changing, compared to some technologies that only use fixed perception nodes (for example, the first node) or only use fixed perception detection modes to perform perception detection on the perception target, it may cause perception failure within a certain period of time or interruption of the mobile position point of the perception target. The embodiment of the present disclosure can flexibly select the perception node and perception detection mode when performing perception detection on the perception target by indicating the perception detection mode of the second node, thereby improving the efficiency and accuracy of perception.

[0070] In some embodiments, the sensing detection mode includes at least one of the following: a first sensing detection mode, a second sensing detection mode, and a third sensing detection mode. The first sensing detection mode is used to instruct the second node to receive a first echo signal for a first sensing signal, where the first sensing signal is a sensing signal sent by the first node; the second sensing detection mode is used to instruct the second node to send a second sensing signal and receive a second echo signal for the second sensing signal; and the third sensing detection mode is used to instruct the second node to receive a third echo signal for a third sensing signal, where the third sensing signal is a sensing signal sent by a third node, where the third node is a node other than the first node and the second node.

[0071] It is understandable that the method provided by the embodiment of the present disclosure can achieve diversified perception methods through diversified perception detection modes. Each perception detection mode can be targeted at different perception nodes and have different functions in different scenarios and applications. By instructing the second node to use a different perception detection mode, the first node can flexibly adjust the perception detection method based on specific needs and environmental conditions when perceiving and detecting the perception target, thereby improving the accuracy of perception detection and avoiding perception interruption or failure.

[0072] In some embodiments, the first perception signal, the second perception signal, and the third perception signal satisfy at least one of the following: the first perception signal, the second perception signal, and the third perception signal are orthogonal to each other; the first perception signal, the second perception signal, and the third perception signal are time-division multiplexed to each other; the first perception signal, the second perception signal, and the third perception signal are frequency-division multiplexed to each other; and the first perception signal, the second perception signal, and the third perception signal are code-division multiplexed to each other.

[0073] It can be understood that the first perception signal, the second perception signal and the third perception signal can reduce the mutual interference between different types of perception signals by satisfying pairwise orthogonality, time division multiplexing, frequency division multiplexing or code division multiplexing, thereby improving the reliability and accuracy of perception detection of the perception target and avoiding interference between different perception signals and the impact on the perception detection results.

[0074] In some embodiments, the first information is carried in radio resource control (RRC) signaling, and the first information may indicate the second node based on different methods.

[0075] In some embodiments, the first information includes a bitmap. The bitmap includes multiple indicator bits, each indicator bit corresponds to a sensing detection mode, and each indicator bit is used to indicate whether the sensing detection mode corresponding to the indicator bit is the sensing detection mode used by the second node.

[0076] In some embodiments, the first information may include a 3-bit bitmap b1b2b3. The indicator bit b1 corresponds to the first perception detection mode, the indicator bit b2 corresponds to the second perception detection mode, and the indicator bit b3 corresponds to the third perception detection mode. The value of each indicator bit can be used to indicate whether the perception detection mode corresponding to the indicator bit is the perception detection mode used by the second node. For example, if the value of the indicator bit is 0, it can indicate that the perception detection mode corresponding to the indicator bit is not the perception detection mode used by the second node; if the value of the indicator bit is 1, it can indicate that the perception detection mode corresponding to the indicator bit is the perception detection mode used by the second node. Exemplarily, if the bitmap is 110, it indicates that the perception detection mode used by the second node is the first perception detection mode and the second perception detection mode; if the bitmap is 010, it indicates that the perception detection mode used by the second node is the second perception detection mode.

[0077] It should be noted that the perception detection mode corresponding to each indicator bit in the above bitmap is only an example given in the embodiment of the present disclosure. In actual implementation, the perception detection mode corresponding to each indicator bit can be flexibly selected according to different actual conditions, and the embodiment of the present disclosure does not limit this.

[0078] It is understood that, compared to transmitting detailed information about each sensory detection mode, the disclosed embodiments can effectively reduce the amount of information transmitted by indicating the sensory detection mode using a bitmap. Furthermore, through the design of the bitmap and indicator bits, the first node only needs to modify the definitions of the bitmap and indicator bits, without changing the transmission method and mechanism, to expand the number of sensory detection modes. This reduces the complexity of the first node instructing the second node on the sensory detection mode to use, and also makes sensory detection of the sensory target more flexible.

[0079] In some embodiments, the first information includes a first field, and the value set of the first field includes multiple values. Exemplarily, the first field can use 2-bit indication information, for example, the indication information can be: 00, 01, 10, 11. In this case, the value set corresponding to the 2-bit indication information includes: 0, 1, 2, 3. In some embodiments, each of the multiple values ​​corresponds to at least one perception detection mode. Exemplarily, as shown in Table 1 below, each value corresponds to at least one perception detection mode.

[0080] Table 1

[0081] It should be noted that the at least one sensing detection mode corresponding to each of the above values ​​is only an example given in the embodiment of the present disclosure. In some embodiments, depending on the actual situation, the sensing detection mode corresponding to each value may also be different, and the embodiment of the present disclosure does not limit this.

[0082] It can be understood that the method provided by the embodiment of the present disclosure uses a value set of the first domain to represent different perception detection modes, and each value can be associated with a specific perception detection mode. The second node only needs to determine the perception detection mode to be used based on the value of the first domain without further parsing complex information. At the same time, the value set of the first domain can be flexibly defined and expanded based on actual needs. If it is necessary to increase the perception detection mode to be performed, the first node can expand the first domain by adding new values ​​without causing a significant impact on the transmission mechanism or method. In addition, compared to transmitting detailed perception detection modes, the method provided by the embodiment of the present disclosure indicates different perception detection modes through the values ​​of the first domain, and the values ​​of the first domain usually use a smaller number of bits, and the amount of information transmitted is smaller, which can save channel resources and improve channel utilization.

[0083] In some embodiments, the first node can send first information with different contents to the second node based on information such as changes in the channel environment, the distance between the perception target and each node in the perception network, so that the second node uses different perception detection modes to perform perception detection on the perception target.

[0084] As an example, the sensing detection mode indicated by the first information is described using the example of a first node's changing distance from a sensing target to each node in the sensing network. As shown in Figure 3, if the sensing target is a car, and the car is near the first node in Cell 1, the first node can send a first sensing signal to the car and receive a first echo signal from the car in response to the first sensing signal. As shown in Figure 4, when the car moves from a position near the first node to a position near a second node in Cell 1, the first node can send a first information to the second node, instructing the second node to use the first sensing detection mode so that the second node receives the first echo signal. As shown in Figure 5, when the car moves into the overlapping area of ​​Cells 1 and 2, the first node can send a first information to the second node, instructing the second node to use the first sensing detection mode, the second sensing detection mode, and the third sensing detection mode. In other words, the second node is instructed to receive the first echo signal, the second echo signal, and the third echo signal. As shown in Figure 6, when the car moves to a position close to the third node in cell 2, the first node can send a first message to the second node, instructing the second node to adopt a third perception detection mode so that the second node receives a third echo signal.

[0085] It should be noted that the above-mentioned determination by the first node of the sensing detection mode indicated in the first indication information based on the distance between the sensing target and each node in the sensing network is merely an example provided in the embodiments of this disclosure. In some embodiments, the first node may determine the sensing detection mode indicated in the first information based on a comprehensive assessment of information such as the mobile location of the sensing target, the motion state of the sensing target, and the signal strength of each node in the sensing network.

[0086] It can be understood that in the method provided by the embodiment of the present disclosure, the first node sends first information with different contents based on information such as changes in the channel environment and the distance between the perception target and the node. The most appropriate perception detection mode can be selected based on actual conditions to meet the perception requirements under different scenarios and needs, thereby improving the perception effect and accuracy.

[0087] In some embodiments, as shown in FIG7 , the above method further includes: S102 .

[0088] S102: Receive the perception detection result sent by the second node.

[0089] In some embodiments, the second node performs sensing detection on the sensing target based on the sensing detection mode indicated in the first information, and receives an echo signal sent by the sensing target. After receiving the echo signal, the second node measures the echo signal and sends a sensing detection result of the echo signal to the first node.

[0090] In some embodiments, the sensing detection result includes at least one of the following: received signal strength indication (RSSI), signal-to-noise ratio (SNR), and bit error rate (BER).

[0091] It can be understood that by receiving the perception detection results sent by the second node, the first node can promptly receive the collaborative perception results of the second node on the perception target, so that the first node can obtain accurate information of the perception target in a timely manner and improve the accuracy of perception detection.

[0092] Refer to Figure 8, which is a flow chart of another information indication method provided by an embodiment of the present disclosure. As shown in Figure 8, the information indication method provided by an embodiment of the present disclosure is applied to the second node and can be implemented as follows S201.

[0093] S201: Receive first information sent by a first node.

[0094] The first information is used to indicate the perception detection mode used by the second node.

[0095] In some embodiments, the implementation of S201 may refer to the above-mentioned S101, and the embodiments of the present disclosure will not be repeated here.

[0096] It can be understood that, based on the information indication method provided by the embodiment of the present disclosure, the second node (for example, the terminal) can receive the first information sent by the first node (for example, the base station), so that after receiving the first information, the second node can select the perception detection mode used by the second node based on the indication of the first information. When the first node is performing perception detection on the perception target, the second node can use the perception detection mode indicated by the first information to assist the first node in collaborative perception of the perception target, thereby reducing the perception burden of the first node. At the same time, since the position and state of the perception target are constantly changing, compared to some technologies that only use fixed perception nodes (for example, the first node) or only use fixed perception detection modes to perform perception detection on the perception target, it may cause perception failure within a certain period of time or interruption of the mobile position point of the perception target. The embodiment of the present disclosure can flexibly select the perception node and perception detection mode when performing perception detection on the perception target by indicating the perception detection mode of the second node, thereby improving the efficiency and accuracy of perception.

[0097] In some embodiments, as shown in FIG9 , after S201 , the method further includes:

[0098] S202: Send the perception detection result to the first node.

[0099] In some embodiments, after receiving the first information, the first node receives an echo signal sent by the sensing target based on the sensing detection mode indicated by the first information. After receiving the echo signal, the first node measures the echo signal to obtain a sensing detection result, and sends the sensing detection result to the first node.

[0100] In some embodiments, the sensing detection result includes at least one of the following: RSSI, SNR, BER.

[0101] In some embodiments, the second node sends the perception detection result to the first node, as shown in FIG10 , which can be implemented as: S2021 - S2022 .

[0102] S2021. Determine whether the perception detection result meets the threshold requirement.

[0103] In some embodiments, the second node processes RSSI, SNR, and other data in the sensing detection results and compares them with pre-set thresholds to determine whether the sensing detection results meet threshold requirements. For example, the threshold requirements may be: RSSI greater than -80dBm, SNR greater than 10dB, and no BER requirement.

[0104] It should be noted that the above threshold requirement is only an example given in the embodiment of the present disclosure. During implementation, the threshold requirement may vary according to actual conditions, and the embodiment of the present disclosure does not limit this.

[0105] S2022: When the perception detection result meets the threshold requirement, send the perception detection result to the first node.

[0106] It can be understood that in the method provided by the embodiment of the present disclosure, the second node sends the perception detection result to the first node when the perception detection result meets the threshold requirement, which can ensure that the information obtained by the first node is screened and verified, which is conducive to improving the accuracy and reliability of the perception detection result.

[0107] Referring to Figure 11, Figure 11 is a flow chart of another information indication method provided by an embodiment of the present disclosure. As shown in Figure 11, the information indication method provided by an embodiment of the present disclosure is applied to a first node and can be implemented as follows S301-S302.

[0108] S301. Send second information to a second node.

[0109] The second information is used to configure at least one sensing resource set for the second node.

[0110] In some embodiments, the second information is carried in radio resource control (RRC) signaling. The first node may configure at least one sensing resource set for the second node through RRC signaling.

[0111] In some embodiments, the second information sent by the first node to the second node includes relevant parameters for configuring the sensing resource set. For example, power parameters, time parameters, frequency parameters, and spare parameters. Power parameters include: energy per resource element (EPRE). Time parameters include: sensing orthogonal frequency division multiplexing (OFDM) symbol interval, sensing frame duration, and sensing result update period. Frequency parameters include: sensing subcarrier spacing and bandwidth. Spatial parameters include: antenna aperture and beam pointing.

[0112] It should be noted that the above-mentioned parameters for configuring the perception resource set are only an example given in the embodiment of the present disclosure. During implementation, more or less parameter information can be configured for the perception resource set according to different actual conditions, and the embodiment of the present disclosure does not limit this.

[0113] It can be understood that in the method provided by the embodiment of the present disclosure, the first node (for example, a base station) configures at least one perception resource set for the second node (for example, a terminal) by sending second information to the second node, thereby achieving reasonable allocation and management of perception resources and improving the performance and resource utilization of the perception network.

[0114] S302: Send third information to the second node.

[0115] The third information is used to activate the target sensing resource set, where the target sensing resource set belongs to at least one sensing resource set.

[0116] In some embodiments, after receiving the third information, the second node may activate the target perception resource set based on the instruction of the third information, so that the second node can subsequently receive the echo signal of the perception target based on the target perception resource set.

[0117] In some embodiments, the third information is further used to indicate a sensing detection mode used by the second node on the target sensing resource set.

[0118] It should be noted that some contents of the perception detection mode can be referred to the description in S101 above, and will not be repeated here in the embodiment of the present disclosure.

[0119] It is understandable that by activating the target perception resource set by sending the third information to the second node, the first node can, when the first node performs perception detection on the perception target, assist the second node in collaboratively perceiving the perception target based on the target perception resource set, thereby reducing the perception burden of the first node. In addition, the first node dynamically schedules perception resources through the third information, that is, the first node can flexibly schedule different perception resource sets for the first node based on perception needs, so that the second node has diversified perception capabilities, thereby making the detection of perception targets more flexible and efficient.

[0120] In some embodiments, the third information includes a second field, and the value set of the second field includes multiple values. Exemplarily, the second field can use 2-bit indication information. For example, the indication information can be: 00, 01, 10, 11. In this case, the value set corresponding to the 2-bit indication information (i.e., the second field) is: 0, 1, 2, 3.

[0121] As an example, the value set of the second domain includes multiple first values, each of the multiple first values ​​corresponds to at least one perception resource set; the value of the second domain is the first value, which is used to indicate that the target perception resource set is the at least one perception resource set corresponding to the first value. Exemplarily, the first value includes: 1, 2, and 3.

[0122] In some embodiments, each of the multiple first values ​​corresponds to at least one sensing resource set. For example, as shown in Table 2 below, Table 2 lists at least one sensing resource set corresponding to each first value.

[0123] Table 2

[0124] In some embodiments, each first value among multiple first values ​​also corresponds to at least one perception detection mode; the value of the second domain is the first value, used to indicate that the perception detection mode used by the second node on the target perception resource set is at least one perception detection mode corresponding to the first value.

[0125] Exemplarily, when the first value is 1, it may correspond to the first sensing detection mode, and the target sensing resource set is sensing resource set 1. The first value is used to indicate that the sensing detection mode used by the second node on sensing resource set 1 is the first sensing detection mode. When the first value is 2, it may correspond to the first sensing detection mode and the second sensing detection mode, and the target sensing resource set is sensing resource set 2. The first value is used to indicate that the sensing detection mode used by the second node on sensing resource set 2 is the first sensing detection mode and the second sensing detection mode.

[0126] As another example, the value set of the second field also includes a second value; the value of the second field is the second value, which is used to instruct the second node not to perform perception detection. Exemplarily, the second value is 0. When the second node receives the third information and parses the third information to find that the value of the second field is 0, the second node does not perform perception detection on the perception target.

[0127] It can be understood that the method provided by the embodiment of the present disclosure uses a set of values ​​of the second domain to represent different perception detection modes, and each value can be associated with a specific perception detection mode. The second node only needs to determine the perception detection mode to be used based on the value of the second domain, or not to perform perception detection, without further parsing complex information. At the same time, the value set of the second domain can be flexibly defined and expanded based on actual needs. If it is necessary to increase the perception detection modes that can be performed, the first node can expand the second domain by adding new values ​​without causing a significant impact on the transmission mechanism or method. In addition, compared to transmitting detailed perception detection modes, the method provided by the embodiment of the present disclosure indicates different perception detection modes through the values ​​of the second domain, and the values ​​of the second domain usually use a smaller number of bits, and the amount of information transmitted is smaller, which can save channel resources and improve channel utilization.

[0128] In some embodiments, the third information is carried in downlink control information (DCI). The DCI can be a newly defined DCI domain in the 5G protocol, or it can reuse an existing DCI domain. Taking into account that the nodes in the edge cell (e.g., UE) have a low modulation and coding scheme (MCS) value, the high bits of the MCS domain can be reused at this time. For example, the high k bits of the MCS domain in the DCI are used, or the high k bits or all bits of the MCS domain of transport block 2 are used, or the redundant version (RV) domain of transport block 2 is used.

[0129] In some embodiments, the DCI is a group common DCI (i.e., DCI formats for other purposes) or a UE specific DCI (i.e., DCI scheduled by a physical downlink shared channel (PDSCH) and / or DCI scheduled by a physical uplink shared channel (PUSCH).

[0130] In some embodiments, for group-shared DCI, a fixed set of radio network temporary identifiers (RNTIs) may be used for scrambling, for example, scheduling frame RNTIs (SF-RNTIs) may be used for scrambling. For example, the DCI format after scrambling with RNTI is as follows:

[0131] DCI format 2_x: block number 1, block number 2, ..., block number N. Exemplarily, x is an integer greater than or equal to 8.

[0132] The block number represents different fields in the DCI, and the first node configures the starting position of the block for the second node through high-layer signaling.

[0133] It is understood that the method provided by the embodiments of the present disclosure uses RNTI to scramble DCI. Only nodes with the correct RNTI can correctly parse the field information in the DCI, preventing other nodes from obtaining or interfering with the DCI content. This improves the security and anti-interference capabilities of sensor detection. Furthermore, by adjusting block numbers and setting different fields, it can flexibly adapt to different sensor needs and scenarios, further enhancing the flexibility of sensor detection.

[0134] In some embodiments, as shown in FIG12 , the above method further includes: S303 .

[0135] S303: Receive the perception detection result sent by the second node.

[0136] In some embodiments, the second node performs sensing detection on the sensing target based on the target resource set and the sensing detection mode indicated in the third information, and receives an echo signal sent by the sensing target. After receiving the echo signal, the second node measures the echo signal and sends a sensing measurement result of the echo signal to the first node.

[0137] In some embodiments, the sensing detection result includes at least one of the following: received signal strength RSSI, signal-to-noise ratio SNR, and bit error rate BER.

[0138] It can be understood that by receiving the perception detection results sent by the second node, the first node can promptly receive the collaborative perception results of the second node on the perception target, so that the first node can obtain accurate information of the perception target in a timely manner and improve the accuracy of perception detection.

[0139] Refer to Figure 13, which is a flow chart of another information indication method provided by an embodiment of the present disclosure. As shown in Figure 13, the information indication method provided by an embodiment of the present disclosure is applied to the second node and can be implemented as follows S401-S402.

[0145] It can be understood that, based on the information indication method provided by the embodiment of the present disclosure, the second node (for example, the terminal) receives the second information sent by the first node (for example, the base station) to determine at least one resource set configured by the first node, which can realize the reasonable allocation and management of the perception resources and improve the performance and resource utilization of the perception network. At the same time, the second node activates the target perception resource set by receiving the third information sent by the first node, so that when the first node performs perception detection on the perception target, the second node can assist the first node in collaborative perception of the perception target based on the target perception resource set, thereby reducing the perception burden of the first node. In addition, the second node activates the target perception resource set based on the third information, that is, the second node flexibly uses different perception resources based on the third information, which can enable the second node to have diversified perception capabilities, thereby making the detection of the perception target more flexible and efficient.

[0146] In some embodiments, as shown in FIG14 , the above method further includes: S403 .

[0147] S403: Send the perception detection result to the first node.

[0148] In some embodiments, after receiving the third information, the second node receives an echo signal sent by the sensing target based on the target sensing resource set and sensing detection mode indicated by the third information. After receiving the echo signal, the second node measures the echo signal to obtain a sensing detection result, and sends the sensing detection result to the first node.

[0149] In some embodiments, the sensing detection result includes at least one of the following: RSSI, SNR, BER.

[0150] In some embodiments, as shown in FIG15 , the above S403 may be implemented as follows:

[0151] S4031. Determine whether the perception detection result meets the threshold requirement.

[0152] S4032: When the perception detection result meets the threshold requirement, send the perception detection result to the first node.

[0153] In some embodiments, the implementation of the above S4031-S4032 can refer to the above S2021-S2022, and the embodiments of the present disclosure will not be repeated here.

[0154] It can be understood that in the method provided by the embodiment of the present disclosure, the second node sends the perception detection result to the first node when the perception detection result meets the threshold requirement, which can ensure that the information obtained by the first node is screened and verified, which is conducive to improving the accuracy and reliability of the perception detection result.
