[0025] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.

[0026] In the description of the present disclosure, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this article is only used to describe the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: only A, only B, and A and B. In addition, "at least one" means one or more, and "a plurality" means two or more. Words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not limit them to be necessarily different.

[0027] It should be noted that, in this disclosure, words such as "exemplary" or "for example" are used to describe examples, illustrations, or explanations. Any embodiment or design described in this disclosure using words such as "exemplary" or "for example" should not be interpreted as being more preferred or advantageous than other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0028] Currently, ISAC allows wireless networks to support context awareness. However, related technologies do not disclose how to enable context awareness in wireless networks. Therefore, how to enable context awareness in wireless networks (including the specific signaling interaction process) is an urgent problem to be solved.

[0029] During the ISAC process, the receiving device receives a known reference signal (RS). The receiving device can obtain the time when the transmitter sends the reference signal, the frequency at which the reference signal is sent, and each bit of data in the reference signal. Then, when the receiving device receives other signals, the channel response h is calculated by performing matched filtering on the received signal y and the known reference signal x. In this process, there is a linear relationship y = h*x between the received signal y and the reference signal x, where * represents the convolution operator. The above process is similar to the channel estimation process, and both use a known RS to estimate the channel.

[0030] After the receiving device obtains channel information by calculating the channel response, it can perform local calculations based on this information to identify, detect, and track targets, or image the surrounding environment. Furthermore, with sufficient perception resolution, the receiving device can detect any moving or stationary object, regardless of whether it is a user device connected to the network or other devices not connected to the network.

[0031] ISAC has multiple operating modes, the two most common of which are monostatic and bistatic. The difference between these two modes lies in whether the ISAC's transmitter and receiver are the same device.

[0032] For example, as shown in FIG1 , it is a schematic diagram of the architecture of an ISAC in a single-state working mode according to an embodiment of the present disclosure. In the single-state working mode, the transmitter and the receiver are the same device. For example, case 1 in FIG1 is a line of sight (LOS) echo situation, where the signal is transmitted in a straight line between base station (BS) 1 and sensing target 2, and is reflected back to base station 1 by sensing target 2. Case 2 in FIG1 is a non-line-of-sight situation, where the signal is reflected by obstacles, buildings, etc. during the transmission process before reaching sensing target 2.

[0033] As another example, as shown in FIG2 , it is a schematic diagram of the architecture of the ISAC in the dual-state working mode according to an embodiment of the present disclosure. In the dual-state working mode, the transmitting end and the receiving end are not the same device. For example, as shown in Case 1 in FIG2 , the sensing signal sent by the base station 1 is reflected by the sensing target 2, and the signal arrives at the base station 3. As shown in Case 2 in FIG2 , the sensing signal sent by the base station 1 passes through scatterers such as obstacles or buildings, and is reflected again at the sensing target 2, and the signal finally arrives at the base station 3. As shown in Case 3 in FIG2 , the sensing signal sent by the base station 1 is reflected at the sensing target 2, and is reflected again by scatterers such as obstacles or buildings in the environment, and finally arrives at the base station 3. As shown in Case 4 in FIG2 , the sensing signal sent by the base station 1 is first reflected by scatterers such as obstacles or buildings, and is reflected again at the sensing target 2, and then is reflected again by scatterers such as obstacles or buildings, and finally arrives at the base station 3.

[0034] In Figures 1 and 2 above, base stations can perform environmental sensing. Correspondingly, terminals also want to use licensed spectrum for environmental sensing to meet their needs (such as navigation and environmental monitoring). The principles by which terminals use wireless signals for environmental sensing are similar to those used by base stations.

[0035] Based on this, the present disclosure provides an environment perception method, which can start environment perception in a wireless network by sending a first message request to start environment perception and receiving a second message to start environment perception, so as to facilitate perception and monitoring of the environment.

[0036] The environment perception method provided by the present disclosure may be applied to a communication system as shown in FIG3 , which shows a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0037] As shown in Figure 3, a communication system includes a first node 10 and a second node 20. In a wireless communication scenario, the first node 10 and the second node 20 communicate via a wireless channel. For example, the first node 10 is a terminal and the second node 20 is a base station. The base station and the terminal communicate via a wireless channel. In another example, the first node 10 is a terminal and the second node 20 is a wireless router. The wireless router and the terminal communicate via a wireless channel. In another example, the first node 10 is a first base station and the second node 20 is a second base station. The first and second base stations communicate via a wireless channel. In another example, the first node 10 is a first terminal and the second node 20 is a second terminal. The first and second terminals communicate via a wireless channel. In another example, the first node 10 is a repeater and the second node 20 is a base station. The base station and the repeater communicate via a wireless channel. In another example, the first node 10 is a terminal and the second node 20 is a repeater. The repeater and the terminal communicate via a wireless channel. For another example, the first node 10 is a first repeater, the second node 20 is a second repeater, and the first repeater and the second repeater communicate via a wireless channel. For another example, the first node 10 is a base station, the second node 20 is a satellite, and the satellite and the base station communicate via a wireless channel. For another example, the first node 10 is a satellite, the second node 20 is a base station, and the base station and the satellite communicate via a wireless channel. For another example, the first node 10 is a terminal, the second node 20 is a satellite, and the satellite and the terminal communicate via a wireless channel. For another example, the first node 10 is a satellite, the second node 20 is a terminal, and the terminal and the satellite communicate via a wireless channel. For another example, the first node 10 is a ground device, the second node 20 is an aircraft, and the aircraft and the ground device communicate via a wireless channel. For another example, the first node 10 is a first aircraft, the second node 20 is a second aircraft, and the first aircraft and the second aircraft communicate via a wireless channel.

[0038] In the embodiments of the present disclosure, the first node 10 is mainly used as a terminal and the second node 20 is used as a base station for illustration.

[0039] In some embodiments, the first node 10 can be a device with wireless transceiver capabilities, which can be deployed on land (including indoors or outdoors, handheld, wearable, or vehicle-mounted); can also be deployed on the water (such as a ship); can also be deployed in the air (for example, on an airplane, a balloon, and a satellite). The terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, 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 care, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, and the like. The embodiments of the present disclosure do not limit the application scenarios. The terminal may sometimes also be referred to as 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.

[0040] In some embodiments, the second node 20 is configured to provide wireless access services to multiple terminals. For example, a base station provides a service coverage area (also referred to as a cell). Terminals entering this area can communicate with the base station via wireless signals to receive the wireless access services provided by the base station.

[0041] In some embodiments, the second node 20 may be a base station or an evolved base station (eNB or eNodeB) in long term evolution (LTE), long term evolution advanced (LTE-A), a base station device in a 5G network, or a base station in a future communication system. The base station may include various network-side devices such as various macro base stations, micro base stations, home base stations, wireless remote devices, reconfigurable intelligent surfaces (RIS), routers, and wireless fidelity (WIFI) devices.

[0042] It should be noted that Figure 3 is only an exemplary framework diagram. The number of devices included in Figure 3 and the names of each device are not limited. In addition to the devices shown in Figure 3, the communication system may also include other devices, such as core network devices.

[0043] Figure 4 shows an interactive schematic diagram of an environment perception method according to the present disclosure. As shown in Figure 4 , the environment perception method includes the following S101 and S102.

[0044] In S101, a first node sends a first message to a second node. Correspondingly, the second node receives the first message sent by the first node.

[0045] The first message is used to request to start environmental awareness.

[0046] In some embodiments, the first message includes at least one of the following: the effective time of environmental perception, the duration of environmental perception, the bandwidth resources required for environmental perception, whether continuous time slots are required for environmental perception, the key performance indicator (KPI) of environmental perception, the time domain resources required for environmental perception, the waveform required for environmental perception, the coding or modulation scheme required for environmental perception, and the beamforming parameters required for environmental perception.

[0047] In this way, by sending the first message, the first node can enable the second node to determine the resources required for environmental perception based on the first message after receiving the first message, thereby improving the accuracy of environmental perception and increasing resource utilization.

[0048] It should be understood that when the first node performs environmental perception, it needs to use the authorized spectrum to ensure that the environmental perception is performed within the legal frequency band and avoid interference with other communication systems or equipment. In addition, the authorized spectrum has high reliability and stability, which helps the first node improve the accuracy and reliability of environmental perception. Therefore, when the first node requests to start environmental perception, it needs to request the second node to use the authorized spectrum and request the second node to assist in configuring the resources required for environmental perception through a first message. Correspondingly, the second node authorizes and configures resources for the first node according to the first message to ensure that the first node can effectively use the authorized spectrum and related resources for environmental perception.

[0049] In some embodiments, when the resources required for the first node's environment awareness can be independently configured by the second node, participation of a core network (CN) device is not required.

[0050] Exemplarily, when the first node initiates environmental perception and the resources required for environmental perception are time domain resources and frequency domain resources on a licensed frequency band, the second node can independently configure the time domain resources and frequency domain resources on the licensed frequency band without negotiating with the core network device and without requiring the core network device to initiate an environmental perception session.

[0051] This eliminates the need for core network equipment to configure and allocate environmental awareness resources, reducing communication complexity and latency. The second node can independently configure the resources needed for environmental awareness, enabling faster responses to the first node's environmental awareness needs. This improves resource utilization and ensures timely responses.

[0052] In some embodiments, the first message is at least one of the following: long term evolution positioning protocol (lte positioning protocol, LPP) signaling, physical layer signaling, radio resource control protocol (radio resource control, RRC) signaling.

[0053] Exemplarily, the first node can carry the first message in the LLP signaling and transmit the first message through the LLP signaling. During the sending process, the first node will start a local perception session so that the first node and the second node can interact through the session. The "local" in the local perception session is used to characterize that the core network device does not participate in the session, and the perception function within the core network device does not participate in the session. In order to be able to reuse and be consistent with the design similar to LPP signaling, the process of the session is still defined as a perception process and is classified as a local perception session. Different from the common LPP signaling interaction process, after receiving the LPP signaling, the second node will not forward the LLP signaling to the core network device.

[0054] In another exemplary embodiment, the first node may carry the first message in physical layer signaling, transmit the first message through physical layer signaling, and request physical layer resources without initiating any perception session. When sending the first message, this may be achieved through a physical random access channel (PRACH) during the initial access phase. The first node may directly request the resources required for environmental perception through physical layer signaling without involving local perception functions.

[0055] As another example, the first node may carry the first message in RRC signaling, transmit the first message through RRC signaling, and request physical layer resources without initiating any perception session in the core network device.

[0056] In this way, by carrying the first message in different types of signaling, it can adapt to different needs and scenarios, thereby improving the flexibility and adaptability of communication.

[0057] In S102, the second node sends a second message to the first node. Correspondingly, the first node receives the second message sent by the second node.

[0058] The second message is used to instruct the first node to start environment awareness.

[0059] By sending a first message requesting to start environment perception and receiving a second message to start environment perception, environment perception can be started in a wireless network to facilitate perception and monitoring of the environment.

[0060] In some embodiments, the second message includes at least one of the following: scheduling resources, transmit power, transmit bandwidth, center frequency, waveform, uncertainty, quasi co-located (QCL) relationship or spatial relationship, beamforming parameters, modulation scheme, and modulation symbol.

[0061] The scheduling resource includes at least one of the following: frequency domain resources and time domain resources. The modulation symbol is a modulation symbol on a specific subcarrier.

[0062] In this way, the second node can determine the resources required for the first node's environmental perception based on the first message, and allocate resources to the first node through the second message. It can effectively allocate and schedule resources according to actual needs and resource conditions, thereby improving resource utilization.

[0063] In some embodiments, after receiving the second message, the first node sends a perception signal based on the second message.

[0064] Exemplarily, after receiving the second message, the first node sends a perception signal according to the time domain resources and frequency domain resources carried in the second message to start environment perception.

[0065] In some embodiments, the first node sends a third message to the second node.

[0066] The third message is used to instruct to stop environment sensing.

[0067] Exemplarily, when the first node wishes to terminate the environment sensing in advance, it may send a third message to the second node to instruct it to stop the environment sensing and release the reserved time domain resources and frequency domain resources.

[0068] In this way, when it is necessary to stop environmental sensing, the third message can be used to stop environmental sensing, thereby improving the flexibility of environmental sensing. In addition, by releasing the reserved time domain resources and frequency domain resources, they can be allocated to other tasks, thereby improving resource utilization.

[0069] In some embodiments, the second message is jointly configured by the second node and the core network device. When the first node initiates environmental awareness and the second node is unable to independently configure the resources required for environmental awareness, the core network device's participation is required to enable the first node to successfully initiate environmental awareness. For example, as shown in FIG5 , the environmental awareness method includes the following steps S201 to S204.

[0070] In S201, a first node sends a first message to a second node. Correspondingly, the second node receives the first message sent by the first node.

[0071] The first message is used to request to start environmental awareness.

[0072] In S202, the second node sends a fourth message to the core network device. Correspondingly, the core network device receives the fourth message sent by the second node.

[0073] The fourth message is used to trigger environmental awareness.

[0074] Exemplarily, the fourth message may carry the first message, so that the core network device starts environmental awareness after receiving the fourth message, and configures the resources required for the first node to start environmental awareness according to the first message.

[0075] In S203, the core network device sends the first sub-message to the second node. Correspondingly, the second node receives the first sub-message sent by the core network device.

[0076] The first sub-message is a sub-message of the second message, and the first sub-message includes some resources configured by the core network device for the first node.

[0077] It should be noted that there is a sensing function (SF) network element in the core network equipment, which is similar to the location management function (LMF) network element of the fifth generation mobile communication technology (5G), which can be used to configure the advanced parameters or advanced resources required for the first node to start environmental perception, such as the key performance indicators (KPIs) of environmental perception.

[0078] In S204, the second node sends a second message to the first node. Correspondingly, the first node receives the second message sent by the second node.

[0079] The second message is used to instruct the first node to start environment awareness. The second message includes the first sub-message, and the second message is jointly configured by the second node and the core network device.

[0080] Exemplarily, when the second node receives the parameters or resources configured by the core network device carried in the first sub-message, it obtains the second message in combination with the parameters or resources configured by the second node itself for the first node, and sends the second message to the first node.

[0081] In some embodiments, when a core network device participates in an environment sensing process initiated by a first node, if the first node wishes to terminate the environment sensing process early, it may send a third message to the second node to instruct it to terminate the environment sensing process. Accordingly, upon receiving the third message, the second node sends the third message to the core network device.

[0082] In this way, core network devices participate in the environmental awareness process initiated by the first node. When a second node receives a message or signaling from the first node, it proactively forwards the message or signaling to the core network device. The participation of core network devices enables better management and optimization of environmental awareness processes, ensuring the correct configuration of resources required for environmental awareness, optimizing resource utilization and allocation, and improving the accuracy and effectiveness of environmental awareness.

[0083] In some embodiments, the second node includes at least one of the following: a base station, a server terminal.

[0084] It should be noted that the environmental perception method provided herein is described above using the second node as the base station. When a first node initiates environmental perception, the server terminal can also participate in the process of initiating environmental perception as a second node, configuring the resources or parameters required for environmental perception for the first node without the involvement of core network equipment.

[0085] For example, when the first node is outside the coverage of a base station, the first node initiates environmental awareness without the participation of the base station and core network devices. The first node may initiate environmental awareness based on preset configuration information. The first node may receive a second message or interference uplink control (IUC) information sent from another device and initiate environmental awareness based on the second message or IUC information. The other device may be a server terminal, a reference node, a roadside unit (RUS), etc.

[0086] For example, as shown in FIG6 , taking the first node as a terminal and the second node as a server terminal as an example, the environment perception method provided by the present disclosure includes the following S301 and S302 .

[0087] In S301, the terminal sends a first message to the server terminal. Correspondingly, the server terminal receives the first message sent by the terminal.

[0088] The first message is used to request to start environmental awareness.

[0089] In S302, the server terminal sends a second message to the terminal. Correspondingly, the terminal receives the second message sent by the server terminal.

[0090] The second message is used to instruct the terminal to start environmental awareness.

[0091] It should be noted that, for the relevant description of S301 and S302, reference may be made to the relevant description of S101 and S102 above, which will not be elaborated herein.

[0092] In the case where the second node is a server terminal, the first node hopes to end the environment sensing in advance and may send a third message to the second node to instruct to stop the environment sensing and release the reserved time domain resources and frequency domain resources.

[0093] In some embodiments, the first node includes at least one of the following: a communication user equipment (UE), a reduced capability UE (RedCap UE), an Internet of Things (IoT) terminal, and a base station.

[0094] For example, RedCap UE and IoT terminals have relatively simple functions and limited resources, and can only perform simple environmental awareness. When RedCap UE and IoT terminals request to start environmental awareness, there is no need to involve the core network to save power and reduce latency.

[0095] This helps meet the low power consumption and low latency requirements in specific scenarios, allowing RedCap UE and IoT terminals to successfully initiate environmental perception.

[0096] In another exemplary embodiment, a base station may also initiate environmental sensing as a first node. In this case, another base station, acting as a second node, allocates resources or parameters required for environmental sensing to the first node, without the involvement of core network devices. For example, as shown in FIG7 , taking base station 1 as the first node and base station 2 as the second node, the environmental sensing method provided in the present disclosure includes the following S401 and S402.

[0097] In S401, base station 1 sends a first message to base station 2. Correspondingly, base station 2 receives the first message sent by base station 1.

[0098] The first message is used to request to start environmental awareness.

[0099] In S402 , base station 2 sends a second message to base station 1 . Correspondingly, base station 1 receives the second message sent by base station 2 .

[0100] The second message is used to instruct base station 1 to start environment sensing.

[0101] It should be noted that, for the relevant description of S401 and S402, reference may be made to the relevant description of S101 and S102 above, which will not be elaborated herein.

[0102] When the first node is base station 1 and the second node is base station 2, the first node hopes to end environmental perception early. It can send a third message to the second node to instruct it to stop environmental perception and release the reserved time domain resources and frequency domain resources.

[0103] In another exemplary embodiment, a base station may also initiate environmental sensing as a first node. In this case, when another base station as a second node cannot independently allocate resources or parameters required for environmental sensing to the first node, the participation of a core network device is required. For example, as shown in FIG8 , taking base station 1 as the first node and base station 2 as the second node as an example, and requiring the participation of a core network device, the environmental sensing method provided by the present disclosure includes the following S501 to S504.

[0104] In S501, base station 1 sends a first message to base station 2. Correspondingly, base station 1 receives the first message sent by base station 2.

[0105] The first message is used to request to start environmental awareness.

[0106] In S502 , base station 2 sends a fourth message to the core network device. Correspondingly, the core network device receives the fourth message sent by base station 2 .

[0107] The fourth message is used to trigger environmental awareness.

[0108] In S503, the core network device sends a first sub-message to base station 2. Correspondingly, base station 2 receives the first sub-message sent by the core network device.

[0109] The first sub-message is a sub-message of the second message, and the first sub-message includes some resources configured by the core network device for the first node.

[0110] In S504, base station 2 sends a second message to base station 1. Accordingly, base station 1 receives the second message sent by base station 2.

[0111] The second message is used to instruct base station 1 to start environment sensing. The second message includes the first sub-message, and the second message is jointly configured by base station 1 and the core network device.

[0112] When the core network device participates in the environment sensing process initiated by base station 1, and base station 1 wishes to terminate the environment sensing process early, it sends a third message to base station 2 to instruct it to terminate the environment sensing process. Accordingly, upon receiving the third message, base station 2 sends the third message to the core network device.

[0113] For example, the description of S501 to S504 may refer to the description of S201 to S204, and the present disclosure will not elaborate on them here.

[0114] As a result, when the base station is the first node to initiate environmental perception, it possesses more powerful computing and communication capabilities than the terminal, enabling more flexible resource allocation and improved resource utilization. Furthermore, the base station can better coordinate and optimize environmental perception, responding to network needs more promptly and improving the accuracy of environmental perception.

[0115] In some embodiments, a first node sends a request message to a second node. The second node receives the request message from the first node and determines, based on the request message, whether the environment perception parameters desired by the first node can be allocated to the first node. If so, the second node directly sends the resources or parameters required for environment perception to the first node.

[0116] The request information is used to represent the environment perception parameters expected by the first node. For example, the environment perception parameters may include resources or parameters required for environment perception.

[0117] In other embodiments, the first node sends a request message to the second node. In response, the second node receives the request message sent by the first node and determines, based on the request message, whether the environment perception parameters desired by the first node can be allocated to the first node. If not, the second node sends a rejection response message to the first node.

[0118] The rejection response information is used to indicate that the resources or parameters required for environment perception cannot be provided to the first node.

[0119] For example, when the first node receives a rejection response message sent by the second node, it can resend the request message to other second nodes until the environment sensing is successfully started. The second node can be a base station, a server terminal, a SF network element, etc.

[0120] This allows the first node to directly send a request, and the second node to respond based on the request, reducing unnecessary communication and improving communication efficiency. The second node can then allocate resources or send a rejection response based on the actual situation, avoiding resource waste and improving resource utilization. The first node can also choose to switch to another second node to resend the request, improving flexibility.

[0121] In some embodiments, a core network device can serve as an intermediate node between a first node and a second node, not only configuring resources or parameters required for environmental awareness for the first node, but also forwarding signaling or messages sent by the first node to the second node. For example, as shown in FIG9 , when the core network device serves as an intermediate node, the environmental awareness method provided by the present disclosure includes the following steps S601 to S604.

[0122] In S601, a first node sends a first message to a core network device. Correspondingly, the core network device receives the first message sent by the first node.

[0123] The first message is used to request to start environmental awareness.

[0124] In S602, the first node sends a fourth message to the core network device. Correspondingly, the core network device receives the fourth message sent by the first node.

[0125] The fourth message is used to trigger environmental awareness.

[0126] In S603, the core network device sends a second message to the second node. Correspondingly, the second node receives the second message sent by the core network device.

[0127] The second message is used to instruct the first node to start environment awareness.

[0128] In S604, the core network device sends a second message to the first node. Correspondingly, the first node receives the second message sent by the core network device.

[0129] The second message is used to instruct the first node to start environment awareness.

[0130] Exemplarily, in steps S603 to S604, when the core network sends the second message to the first node and the second node, the core network device may also send the second message in the form of a first sub-message and a second sub-message, respectively. For example, the core network device sends the first sub-message to the second node, and the core network device sends the first sub-message to the first node. The core network device sends the second sub-message to the second node, and the core network device sends the second sub-message to the first node. The first sub-message includes high-level parameters or high-level resources required for the first node to initiate environmental awareness, which may be a KPI for environmental awareness. The second sub-message includes non-high-level parameters or non-high-level resources required for the first node to initiate environmental awareness.

[0131] In another exemplary embodiment, if the first node wishes to terminate environmental sensing early, the first node may send a third message to the core network device to instruct it to terminate environmental sensing. Accordingly, upon receiving the third message, the core network device sends the third message to the second node. Alternatively, the first node may send the third message to both the core network device and the second node.

[0132] In this way, the core network equipment can determine the optimal configuration for the first node based on the overall network status and requirements, and provide feedback to the first and second nodes. This allows for better adaptation to changes in the overall network environment and requirements, improving adaptability. Furthermore, direct interaction between the first node and the core network equipment reduces the interaction between the first and second nodes, reducing network load.
