[0037] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0038] The network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. A person skilled in the art will appreciate that, with the evolution of the network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems.

[0039] Please refer to FIG1 , which shows a schematic diagram of a network architecture 100 provided by an embodiment of the present application. The network architecture 100 may include: a terminal device 10 , an access network device 20 , and a core network element 30 .

[0040] The terminal device 10 may refer to a UE, a STA (Station), an access terminal, a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a wireless communication device, a user agent, or a user apparatus. In some embodiments, the terminal device 10 may also be a cellular phone, a cordless phone, a SIP (Session Initiation Protocol) phone, a WLL (Wireless Local Loop) station, a PDA (Personal Digital Assistant), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a 5GS (5th Generation System) or a terminal device in a future evolved PLMN (Public Land Mobile Network), etc., and the embodiments of the present application are not limited thereto. For ease of description, the above-mentioned devices are collectively referred to as terminal devices. The number of terminal devices 10 is generally multiple, and one or more terminal devices 10 may be distributed in each cell managed by an access network device 20. The terminal device may also be referred to as a terminal or UE for short, and those skilled in the art may understand its meaning.

[0041] Access network equipment 20 is a device deployed in an access network to provide wireless communication capabilities for terminal devices 10. Access network equipment 20 may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems employing different wireless access technologies, the names of devices that provide access network equipment functions may vary. For example, in 5G NR systems, they are referred to as gNodeBs or gNBs. As communication technologies evolve, the term "access network equipment" may change. For ease of description, in the embodiments of this application, the aforementioned devices that provide wireless communication capabilities for terminal devices 10 are collectively referred to as access network equipment. In some embodiments, access network equipment 20 enables communication between terminal devices 10 and core network elements 30. For example, in an LTE (Long Term Evolution) system, access network equipment 20 may be an Evolved Universal Terrestrial Radio Access Network (EUTRAN) or one or more eNodeBs within EUTRAN. In a 5G NR system, access network equipment 20 may be a Radio Access Network (RAN) or one or more gNBs within the RAN. In the embodiment of the present application, unless otherwise specified, the "network device" refers to the access network device 20, such as a base station.

[0042] The core network element 30 is a network element deployed in the core network. The functions of the core network element 30 are mainly to provide user connection, user management, and service bearer, and to provide an interface to the external network as a bearer network. For example, the core network elements in the 5G NR system may include network elements such as the AMF (Access and Mobility Management Function) entity, the UPF (User Plane Function) entity, and the SMF (Session Management Function) entity.

[0043] In some embodiments, the access network device 20 and the core network element 30 communicate with each other via an air interface technology, such as the NG interface in the 5G NR system. The access network device 20 and the terminal device 10 communicate with each other via an air interface technology, such as the Uu interface.

[0044] The "5G NR system" in the embodiments of the present application may also be referred to as a 5G system or an NR system, but those skilled in the art will understand its meaning. The technical solutions described in the embodiments of the present application may be applicable to LTE systems, 5G NR systems, and subsequent evolution systems of 5G NR systems (e.g., B5G (Beyond 5G) systems, 6G systems (6th Generation System, sixth generation mobile communication systems)), and other communication systems such as NB-IoT (Narrow Band Internet of Things) systems, which are not limited in this application.

[0045] In an embodiment of the present application, the network device can provide services for a cell, and the terminal device communicates with the network device through the transmission resources (for example, frequency domain resources, or spectrum resources) on the carrier used by the cell. The cell can be a cell corresponding to the network device (for example, a base station). The cell can belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0046] Before introducing the technical solutions of this application, we first introduce and explain some of the relevant technical knowledge involved in this application. The following related technologies can be combined with the technical solutions of the embodiments of this application as optional solutions, and they all fall within the scope of protection of the embodiments of this application. The embodiments of this application include at least part of the following contents.

[0047] The 5G network system architecture is shown in Figure 2. Among them, the UE connects to the AN at the access layer through the Uu port, exchanges access layer messages and wireless data transmission, and connects to the AMF at the non-access layer (None Access Stratum, NAS) through the N1 port, and exchanges NAS messages. AMF is the mobility management function in the core network, and SMF is the session management function in the core network. In addition to managing the mobility of the UE, the AMF is also responsible for forwarding session management-related messages between the UE and the SMF. PCF (Policy Control Function) is a policy management function in the core network, responsible for formulating policies related to UE mobility management, session management, billing, etc. UPF is a user plane function in the core network, which transmits data with the external data network through the N6 interface and with the AN (Access Network) through the N3 interface.

[0048] 1. Definition of Wireless Sensing

[0049] In the integration of communication and perception, the perception capability focuses on wireless signal perception, that is, by analyzing the direct, reflected, and scattered signals of radio waves, the perception of the environment and / or target object information in the environment (such as attributes and status, etc.) is obtained, and the positioning, ranging, speed measurement, imaging, detection, identification, environmental reconstruction and other functions are completed to realize the perception exploration of the physical world.

[0050] - Passive perception: The perception node (network side or terminal) perceives by acquiring electromagnetic waves emitted by the target object (such as terahertz waves) or reflecting electromagnetic waves from outside the perception node and the target object, such as China's passive imaging perception technology in radio astronomy.

[0051] Active sensing: A transmitting node (network or terminal) transmits electromagnetic waves. After reflection from a target object, a receiving node receives the echo for sensing. This is an example of active radar-based sensing technology that transmits a detection signal. The node that receives the reflected wave is not necessarily the same node that sent the detection signal. In other words, multiple sensing nodes can achieve active sensing through some form of joint processing.

[0052] Per-Area / Object Sensing: 5G-A synaesthesia scenarios can be divided into Per-Area synaesthesia scenarios and Per-Object synaesthesia scenarios, depending on whether the perception requirements are primarily focused on a designated perception area or a designated perception target. Perception needs are ubiquitous across all industries. We call these Per-Area synaesthesia scenarios the scenarios that require efficient perception of the real-time status of roads, vehicles, and people in factories, roads, low altitudes, cities, and even larger time and space ranges. We call these Per-Object synaesthesia scenarios the scenarios that utilize synaesthesia technology to continuously perceive and track the perceived objects in order to obtain dynamic monitoring of the perceived object's status.

[0053] Device-based / free sensing: As shown in Figure 3, sensing scenarios can be categorized into device-based and device-free scenarios based on whether the sensing target has the ability to send or receive signals. For example, in flight path management and base station and terminal beam management, the sensing targets, drones and terminals, are user devices with the ability to send or receive signals, thus falling into the device-based scenario. In weather monitoring and respiratory monitoring, the sensing targets, rain and people, are targets without the ability to send or receive signals, thus falling into the device-free scenario.

[0054] 2. Perception scenarios and use cases

[0055] In smart transportation scenarios, based on integrated communication and perception base stations or collaboration between base stations, perception of the road environment is achieved, high-precision map construction is effectively realized, and beyond-line-of-sight assistance is provided for the safe operation of autonomous vehicles; based on integrated communication and perception base stations or collaboration between base stations, all-round, all-weather, and uninterrupted detection of the movement trajectory and speed of moving vehicles is achieved, and the perception information is uploaded to the processing center, comprehensively improving the intelligent perception capability of the operation status of highways and providing data support for road supervision; based on integrated communication and perception base stations, perception of the railway track environment is achieved, and all-weather foreign object intrusion detection around high-speed railways is realized.

[0056] In smart low-altitude scenarios, all-round and multi-angle perception of the airspace is carried out based on an integrated communication and perception base station or collaboration between base stations, and the perception results are provided to drones. This can provide redundancy for obstacle avoidance warning and improve the success rate of drone obstacle avoidance. Based on an integrated communication and perception base station or collaboration between base stations, full airspace perception is carried out to locate and track drones that intrude into the regulatory range, thereby realizing drone intrusion monitoring for fixed areas.

[0057] In smart life scenarios, based on the collaboration between base stations and terminals, or the spontaneous transmission and reception of terminals, or the collaborative working mode between terminals, breathing monitoring, fitness monitoring, gesture / posture recognition, etc. are carried out by sensing changes in wireless channels. Based on the integrated communication perception base station or the collaboration between base stations, the signal link attenuation in the communication link is measured, and then the relationship between signal link attenuation and weather indicators is analyzed to obtain the corresponding weather indicators for weather monitoring.

[0058] In smart network scenarios, information such as the density and location of idle terminals in a cell can be obtained based on integrated communication-aware base stations or collaboration between base stations to assist in energy conservation and optimization of base station resource scheduling within the cell.

[0059] In smart transportation scenarios, continuous tracking of vehicles and real-time dynamic monitoring of vehicle status can be achieved based on integrated communication and perception base stations or collaboration between base stations. For vehicles with wireless communication capabilities, vehicle perception accuracy can also be improved through vehicle collaborative perception.

[0060] In smart low-altitude scenarios, based on integrated communication and perception base stations or collaboration between base stations, drones that intrude into the regulatory area are located and tracked, and then actions are taken to drive away "illegally flying" drones. For networked drones with wireless communication capabilities, drone collaborative perception can also be used to identify the flight status of the drone, roadblocks in the flight route, etc., to provide auxiliary flight services.

[0061] In smart life scenarios, by carrying a terminal with communication capabilities, based on the collaboration between base stations and terminals, or the spontaneous transmission and reception of terminals, or the collaborative working mode between terminals, breathing monitoring, fitness monitoring, gesture / posture recognition, etc. of a specific human body can be performed to achieve accurate real-time dynamic monitoring.

[0062] In smart network scenarios, synaesthesia technology is used to assist in improving beam management and channel estimation accuracy, enhance the timeliness of terminal beam tracking, improve channel estimation accuracy and reduce feedback overhead.

[0063] 3GPP (Third Generation Partnership Project) Perception

[0064] Current cellular networks, including 5G networks, are used solely for communication. However, the radio electromagnetic wave signals used by cellular networks can be used not only for wireless data transmission and communication but also for environmental perception, such as user motion or gesture recognition, respiratory monitoring, device speed measurement, environmental imaging, and weather monitoring. Therefore, future cellular networks could be considered for use not only for communication and data transmission but also for acquiring sensory information. Table 1 lists some sensory information at different levels.

[0065] Table 1: Perceptual information at different levels

[0066] Currently, discussions are underway to support perception capabilities in B5G networks. This is achieved by adding a sensing control element (Sensing Function) and corresponding processes to support perception functionality in 3GPP networks. When an application sends a perception request for a perception target to the 3GPP core network, the core network selects the correct access network device or auxiliary UE (collectively referred to as a perception node) through the sensing control element or AMF, triggers the ability to perform perception-related wireless measurements, initiates the measurement of perception information, and generates perception results.

[0067] As shown in Figure 4, the main wireless sensing modes of synaesthesia integration are as follows:

[0068] a) Base station echo sensing (gNB autonomous sensing): The base station sends a sensing signal and receives an echo signal.

[0069] b) Inter-base station sensing (gNB-2-gNB sensing): Base station B receives the sensing signal sent by base station A.

[0070] c) Air interface uplink perception (UE-2-gNB perception): The base station receives the perception signal sent by the terminal;

[0071] d) Air interface downlink perception (gNB-2-UE perception): The terminal receives the perception signal sent by the base station;

[0072] e) Terminal echo perception (UE autonomous perception): The terminal sends a perception signal and receives an echo signal;

[0073] f) Inter-terminal perception (UE-2-UE perception): Terminal B receives the perception signal sent by terminal A.

[0074] As shown in Figure 5, it is a possible flowchart of controlling the access network device or UE to perform perception operations. Among them, the perception request in step 1 is triggered by the AF, so it is called the AF-triggered perception process, and the perception request belongs to MT-SR (Mobile Terminated-Sensing Request, perception request terminated by the mobile terminal). In addition to MT-SR, the perception request also includes MO-SR (Mobile Originated-Sensing Request, perception request initiated by the mobile terminal) as described in Figure 4, and NI-SR (Network Induced-Sensing Request, network-induced perception request) that may be triggered by network elements within the network.

[0075] Step 6 in Figure 5 and step 4 in Figure 6 illustrate the air interface awareness signaling process. This process can be categorized based on the interacting network elements: SF-gNB signaling interaction, SF-UE signaling interaction, gNB-UE signaling interaction, and UE-UE signaling interaction. Because different awareness modes involve different types of sensing nodes (UE / gNB), the air interface signaling processes required by these modes also differ, as shown in Table 2.

[0076] Table 2: Air interface signaling processes corresponding to different perception modes

[0077] Sensing modes involving terminal devices include UE-2-gNB, gNB-2-UE, and UE-2-UE. Both UE-2-gNB and gNB-2-UE sensing modes require the gNB to act as the sender or receiver of sensing reference signals. These modes are naturally controlled by the network, with the SF or other core network elements acting as control nodes in the sensing process. For both UE-2-UE and UE-2-UE sensing, in in-coverage (IC) scenarios, the SF and other core network elements can also act as control nodes in the sensing process.

[0078] Figure 7 illustrates the air interface sensing signaling flow for a UE-2-UE sensing mode controlled by an SF. For other sensing modes involving UEs, the air interface sensing signaling flow is similar, requiring only appropriate modifications. For example, for UE-spontaneous sensing, the STx UE (Sensing Transmitting UE) and the SRx UE (Sensing Receiving UE) are the same UE; for UE-2-gNB sensing mode, the gNB replaces the SRx UE; and for gNB-2-UE sensing mode, the gNB replaces the STx UE.

[0079] In addition, as shown in FIG8 , for the terminal perception mode (ie, UE-2-UE perception, UE self-transmitting and self-receiving perception), the perception process also needs to consider the scenario of no network coverage (Out Of Coverage, OOC).

[0080] For OOC scenarios, similar to R18 Sidelink positioning, since the terminal device cannot obtain network coverage, core network elements such as SF cannot participate in the terminal perception process, and the perception process described in Figure 5 does not apply. In this case, it is necessary to select some terminal devices with strong capabilities, and let these terminal roles partially assume some of the SF tasks in the OOC scenario. Therefore, in addition to the two types of perception execution terminals (sensing sending terminals and sensing receiving terminals), it is also necessary to define the terminal roles of sensing service terminals / sensing management terminals (Sensing Server / Management UE).

[0081] Therefore, terminal awareness needs to consider the following different terminal roles:

[0082] -Perception sending terminal: In terminal perception, it is responsible for sending perception reference signals.

[0083] -Perception receiving terminal: In terminal perception, it is responsible for receiving and measuring the perception reference signal and obtaining the perception measurement quantity.

[0084] - Sensing Server UE / Sensing Management Terminal (SS UE): In terminal perception, in OOC scenarios, a logical node that undertakes some SF functions, such as perception measurement processing. It can be one of the perception sending terminal and the perception receiving terminal, or it can be independent.

[0085] In particular, for UE self-transmitting and self-receiving perception, the perception sending terminal and the perception receiving terminal are the same terminal.

[0086] FIG9 is a complete UE-independent sensing service flow chart including only UEs, mainly for OOC scenarios or when the current network does not support sensing services.

[0087] Steps 4-8 are the air interface perception signaling process. For the air interface process of steps 4-8, Figure 10 further provides a terminal-independent UE-2-UE perception air interface flow chart, mainly for OOC scenarios.

[0088] As shown in Figure 11, a control plane protocol stack is provided for the transmission of perception signaling between the UE and the SF. As shown in Figure 12, a user plane protocol stack is provided for the transmission of perception signaling between the UE and the SF.

[0089] The control plane primarily transmits control plane signaling, typically with smaller data volumes. It can usually be transmitted with the highest priority, ensuring reliability and availability. The user plane primarily transmits user data and is therefore suitable for large data volumes. However, its transmission priority is constrained by transmission resources and data QoS (Quality of Service), potentially leading to transmission congestion and longer transmission delays.

[0090] In existing positioning, the LTE Positioning Protocol (LPP) is used point-to-point between the LMF and the target UE to locate the target UE using position-related measurements obtained from one or more reference sources. The signaling exchanged between the UE and LMF via the LPP protocol includes capability information, positioning assistance information, and location information requests and reports. This information is typically relatively small in size and is generally considered control plane signaling.

[0091] Therefore, the LPP protocol is typically transmitted between the LMF and the UE via the control plane protocol stack, known as the control-plane location solution. However, the LPP protocol also supports transmission via the user plane protocol stack, known as the user-plane location solution. Furthermore, existing positioning systems support transitions between the UP solution and the CP solution based on LMF requests or AMF signaling congestion. For example, if the LMF decides to use the UP, the LMF instructs the UE to use the UP for positioning and provides information to establish a secure connection. Positioning messages are then transmitted between the UE and the LMF over this secure connection.

[0092] For perception, the similarity with positioning is that the signaling interaction between UE and SF can still refer to the positioning design, including perception capability information, perception assistance information, perception information request and reporting, etc. Most of its messages still have the characteristics of small data volume of control plane signaling.

[0093] However, in certain perception scenarios, perception measurement results may contain a larger amount of data than positioning measurement results. For example, for the different levels of perception information described in the background, the lower the level of perception information, the less processing it undergoes by the UE, and the larger the data volume. Therefore, perception information reporting messages also have the characteristics of data transmitted on the user plane. The existing control plane is designed for the transmission of small amounts of control signaling. However, transmitting large amounts of signaling on the control plane can cause congestion in control plane signaling. Therefore, there is also a need to transmit perception signaling on the user plane.

[0094] Existing technologies only support network-triggered or UE-triggered UP connection establishment between the UE and LMF, as well as LMF-triggered UP connection modification or termination. Dynamic UP and CP switching within a positioning process is not possible. Furthermore, LPP does not support simultaneous UP and CP transmission, nor does it support the use of UP signaling as part of a CP positioning session.

[0095] Since perception signaling has the dual characteristics of control plane signaling and user plane data, for perception information reporting messages, before the terminal device generates perception data, the network equipment may not be able to accurately determine the amount of data reported each time the perception information is reported. Therefore, it is necessary to design a more flexible conversion scheme between UP and CP for the transmission of perception information.

[0096] Please refer to Figure 13, which shows a flow chart of an information transmission method provided by an embodiment of the present application. The method is performed by a first device. The method may include the following step 1310.

[0097] In step 1310, the first device sends perception signaling using the user plane protocol stack based on the configuration information. The configuration information is used to configure a first condition. The first condition is the condition that the first device uses the user plane protocol stack to transmit perception signaling. The perception signaling is used to transmit perception data.

[0098] In some embodiments, the first device may be a terminal device or a network device.

[0099] In some embodiments, the first device sends awareness signaling to the second device using a user plane protocol stack based on the configuration information. Correspondingly, the second device receives the awareness signaling sent using the user plane protocol stack.

[0100] In some embodiments, the second device may be a terminal device or a network device.

[0101] In some embodiments, the first device and the second device are different devices. In some embodiments, different devices may refer to two devices of different types. For example, the first device is a terminal device and the second device is a network device; another example is the first device is a network device and the second device is a terminal device. In some embodiments, different devices may refer to two devices of the same type, for example, the first device is terminal device 1 and the second device is terminal device 2; another example is the first device is network device 1 and the second device is network device 2. Terminal device 1 and terminal device 2 are different devices, and network device 1 and network device 2 are different devices.

[0102] In some embodiments, the configuration information includes at least one of the following: first indication information, user plane protocol stack configuration information, a first condition, and the duration of a first timer; wherein the first indication information is used to indicate the type of perception signaling that allows the first device to use the user plane protocol stack for transmission.

[0103] In some embodiments, the first indication information includes at least one of the following: a sensing capability report, a request for sensing assistance data, and a sensing information report. Exemplarily, the first indication information indicates a sensing capability report, i.e., allows the first device to transmit the sensing capability report using a user plane protocol stack. Exemplarily, the first indication information indicates a sensing capability report and a request for sensing assistance data, i.e., allows the first device to transmit the sensing capability report and the request for sensing assistance data using a user plane protocol stack.

[0104] In some embodiments, the first indication information may indicate any one or more types of perception signaling generated during the perception process, which are merely illustrative examples in the embodiments of the present application.

[0105] In some embodiments, the user plane protocol stack configuration information includes at least one of the following: QoS rules, a mapping relationship between QoS flows and RBs (Resource Blocks), a target address of a SF, and a target port number.

[0106] Services on IP (Internet Protocol) networks can be divided into real-time and non-real-time services. Real-time services, such as voice services, typically occupy fixed bandwidth, are sensitive to network quality fluctuations, and require high network stability. The bandwidth occupied by non-real-time services is difficult to predict, and traffic bursts are common. These bursts can degrade network quality, cause congestion, increase forwarding latency, and, in severe cases, result in packet loss, leading to reduced service quality or even unavailability.

[0107] The best way to resolve network congestion is to increase bandwidth, but this is unrealistic due to operational and maintenance costs. The most effective solution is to apply a "guaranteed" policy to manage network traffic. Given limited bandwidth resources, QoS allocates bandwidth to various services, providing end-to-end quality of service. For example, QoS can prioritize voice, video, and critical data applications on network devices.

[0108] The target address of the SF is the target address of the device configured as the SF.

[0109] The target port number is used to identify the process that will receive data, for example, to identify the process that will receive the perception data carried in the perception signaling.

[0110] In some embodiments, the first condition includes at least one of the following: the type of perception signaling, which is a type of perception signaling that allows the first device to use the user plane protocol stack for transmission; the data volume of the perception signaling is greater than or equal to the first threshold value; the QoS level of the perception signaling complies with the QoS level condition information; the reliability requirement of the perception signaling complies with the reliability level condition information.

[0111] In some embodiments, the first timer is a prohibition timer. During the operation of the first timer, the first device does not send a request message, and the request message is used to request the use of a user plane protocol stack to send perception signaling.

[0112] In some embodiments, before step 1310, the method further includes: the first device receiving configuration information. In some embodiments, the configuration information may be sent by the second device to the first device, or by another device to the first device, which is not limited in this application. For example, the first device is a terminal device, the second device is a terminal device different from the first device, and the configuration information may be sent to the first device by a network device that has a communication connection with the first device. In some embodiments, the second device sends the configuration information.

[0113] In some embodiments, as shown in FIG. 14 , the method further includes at least one of the following steps 1320 to 1330 .

[0114] Step 1320: The first device receives a capability request message, where the capability request message is used to request the first device to report the user plane protocol stack configuration of the perception signaling.

[0115] Accordingly, the second device sends a capability request message.

[0116] Step 1330: The first device sends capability information, where the capability information is related to the user plane protocol stack configuration of the perception signaling.

[0117] Accordingly, the second device receives the capability information.

[0118] In some embodiments, the capability information may be reported autonomously by the first device, or may be triggered to be reported based on a capability request message sent by the second device, which is not limited in this application.

[0119] In some embodiments, the capability information includes at least one of the following:

[0120] Whether the first device supports the use of a user plane protocol stack to transmit perception signaling;

[0121] Whether the first device supports the use of both the user plane protocol stack and the control plane protocol stack to transmit the perception signaling;

[0122] Whether the first device supports dynamic selection of the user plane protocol stack to transmit perception signaling based on the first condition.

[0123] In some embodiments, the second device sends configuration information to the first device based on the capability information. For example, if the capability information indicates that the first device does not support the use of the user plane protocol stack to transmit perception signaling, the configuration information does not configure the type of perception signaling that the first device is allowed to transmit using the user plane protocol stack, that is, no matter what type of perception signaling the first device wants to transmit, it is not allowed to be transmitted using the user plane protocol stack. For example, if the capability information indicates that the first device supports dynamic selection of the user plane protocol stack to transmit perception signaling based on a first condition, the configuration information may include the first condition. For example, if the capability information indicates that the first device can simultaneously support the use of the user plane protocol stack and the control plane protocol stack to transmit perception signaling, the configuration information may indicate the type of perception signaling allowed to be transmitted using the user plane protocol stack and the type of perception signaling allowed to be transmitted using the control plane protocol stack.

[0124] The technical solution provided in the embodiment of the present application is that the first device determines to adopt the user plane protocol stack to transmit perception signaling based on configuration information, so as to avoid congestion of control plane protocol stack transmission due to excessive amount of data carried in the perception signaling, thereby improving data transmission efficiency and improving the stability of the communication system.

[0125] This application also provides an exemplary embodiment for how the first device uses the user plane protocol stack to transmit perception signaling based on the configuration information.

[0126] Method 1: Based on the first indication information and / or the user plane protocol stack configuration information, the user plane protocol stack is used to transmit the perception signaling

[0127] 1.1 The first device decides whether to use the user plane protocol stack to transmit the perception signaling based on the configuration information

[0128] In some embodiments, based on the first indication information and / or the user plane protocol stack configuration information included in the configuration information, the above step 1310 can be implemented as any one of the following steps 1311 to 1313.

[0129] Step 1311: If the configuration information includes user plane protocol stack configuration information, the first device uses the user plane protocol stack to send perception signaling.

[0130] In some embodiments, when the second device is configured with user plane protocol stack configuration information, the first device uses the user plane protocol stack to send perception signaling.

[0131] Step 1312: If the configuration information includes user plane protocol stack configuration information, and the perception signaling belongs to a perception signaling type that allows the first device to use the user plane protocol stack for transmission, the first device uses the user plane protocol stack to send the perception signaling.

[0132] In some embodiments, when the configuration information includes user plane protocol stack configuration information and first indication information, if the type of perception signaling to be sent by the first device is the perception signaling type indicated in the first indication information, that is, the type of perception signaling to be sent by the first device belongs to the perception signaling type that allows the first device to use the user plane protocol stack for transmission, the first device uses the user plane protocol stack to send the perception signaling.

[0133] Step 1313: If the configuration information does not include user plane protocol stack configuration information, and / or the perception signaling does not belong to the perception signaling type that allows the first device to use the user plane protocol stack for transmission, the first device uses the control plane protocol stack to send the perception signaling.

[0134] In some embodiments, if the configuration information does not include user plane protocol stack configuration information, the first device uses the control plane protocol stack to send the perception signaling. In some embodiments, if the second device is not configured with user plane protocol stack configuration information, the first device uses the control plane protocol stack to send the perception signaling.

[0135] In some embodiments, if the perception signaling does not belong to a type of perception signaling that the first device is allowed to transmit using a user plane protocol stack, the first device transmits the perception signaling using a control plane protocol stack. In some embodiments, when the configuration information includes first indication information, if the type of perception signaling to be transmitted by the first device is not the type of perception signaling indicated in the first indication information, that is, the type of perception signaling to be transmitted by the first device is not a type of perception signaling that the first device is allowed to transmit using a user plane protocol stack, the first device transmits the perception signaling using a control plane protocol stack.

[0136] In some embodiments, as shown in FIG. 14 , the method further includes step 1340 .

[0137] Step 1340: The first device sends fourth indication information, where the fourth indication information is used to instruct the first device to use the user plane protocol stack to send perception signaling.

[0138] Correspondingly, the second device receives the fourth indication information.

[0139] In some embodiments, the fourth indication information includes at least one of the following: a session identifier, a transaction identifier, a sequence number, and a perception signaling type.

[0140] In some embodiments, a session identifier is used to identify messages belonging to the same session. For example, a session ID entity is used as the session identifier. A perception session is used between the SF and the perception node to obtain perception information. A single session is used to support a single perception request (e.g., for a single MT-SR, MO-SR, or NI-SR). Multiple sessions can be used between the same endpoints (SF and perception node) to support multiple different perception requests. In this case, a session identifier can be used to identify messages belonging to the same session to avoid affecting other perception requests.

[0141] In some embodiments, a transaction identifier is used to identify messages belonging to the same transaction. For example, a transaction ID (Transaction IDentity) is used as the transaction identifier. Each perception session includes one or more perception transactions, each of which performs a single operation (such as capability exchange, auxiliary data transmission, or perception information transmission). Transactions in a session can occur serially or in parallel. Transactions are represented by transaction identifiers to associate messages with each other (e.g., requests and responses). Messages in the same transaction can have the same transaction identifier.

[0142] In some embodiments, the sequence number is used to detect duplicate perception signaling at the receiving end. For example, if a receiving end receives two messages with the same sequence number, it indicates that the two messages are duplicate perception signaling. The sequence number can assist the receiving end in checking for duplicates and avoiding duplicate reception and decoding.

[0143] In some embodiments, the perception signaling type includes at least one of the following: perception capability report, request for perception assistance data, perception information report.

[0144] In some embodiments, the fourth indication information is sent using a control plane protocol stack. In some embodiments, if the second device believes that the first device is sending the perception signaling using the control plane protocol stack, and if the first device is sending the perception signaling using the user plane protocol stack, the second device sends the fourth indication information to the second device via the control plane protocol stack, instructing the first device to send the perception signaling using the user plane protocol stack, so that the second device can receive the perception signaling via the user plane protocol stack. This prevents the second device from receiving the perception signaling via the control plane protocol stack, which could cause data transmission failure.

[0145] Through the above method, the first device can determine whether the perception signaling to be sent can be transmitted using the user plane protocol stack based on the user plane protocol stack configuration configured by the configuration information and the perception signaling type allowed to be transmitted using the user plane protocol stack, so that the second device can know whether to receive the perception signaling sent by the first device on the user plane protocol stack or the control plane protocol stack.

[0146] 1.2 The first device decides whether to send a request message based on the configuration information

[0147] In some embodiments, based on the above method, the perception signaling to be sent by the first device needs to be sent using the control plane protocol stack, but the amount of data it carries is large, which may cause congestion of the control plane protocol stack. Therefore, the first device can also send a request message to the second device to request the use of the user plane protocol stack to send the perception signaling.

[0148] In some embodiments, the above step 1310 may be implemented as at least one of the following steps 1314 to 1316 .

[0149] Step 1314: If the configuration information does not include user plane protocol stack configuration information, or the perception signaling does not belong to the perception signaling type that allows the first device to use the user plane protocol stack for transmission, a request message is sent, where the request message is used to request the use of the user plane protocol stack to send the perception signaling.

[0150] Accordingly, the second device receives the request message.

[0151] In some embodiments, the request message may be used to request that all perception signaling be sent using the user plane protocol stack, or may be used to request that part of the perception information be sent using the user plane protocol stack.

[0152] In some embodiments, if the request message is used to request that part of the perception signaling be sent using the user plane protocol stack, the request message may carry identification information of the perception signaling to indicate the perception signaling requested to be sent using the user plane protocol stack by the request message.

[0153] In some embodiments, the request message includes at least one of the following: a session identifier, a transaction identifier, a sequence number, and a perception signaling type.

[0154] In some embodiments, if the first device does not receive the configuration information, it may also send a request message.

[0155] Step 1315: The first device receives second indication information, where the second indication information is used to instruct the first device to use the user plane protocol stack to send perception signaling.

[0156] Correspondingly, the second device sends second indication information.

[0157] In some embodiments, if the configuration information does not indicate the user plane protocol stack configuration information, the second indication information may include the user plane protocol stack configuration information. After receiving the second indication information, the first device uses the user plane protocol stack to send perception signaling based on the user plane protocol stack configuration information.

[0158] In some embodiments, if the first device does not receive the configuration information, the first indication information may include user plane protocol stack configuration information and / or the first indication information. After receiving the second indication information, the first device uses the user plane protocol stack to send the perception signaling based on the user plane protocol stack configuration information and / or the first indication information.

[0159] In some embodiments, the second indication information may be used to indicate that the first device is permitted to use a user plane protocol stack to send perception signaling. Exemplarily, the second indication information may include identification information that permits the first device to use the user plane protocol stack to send perception signaling. If the second indication information indicates the perception signaling, the first device uses the user plane protocol stack to send the perception signaling. If the second indication information does not indicate the perception signaling, the first device uses the control plane protocol stack to send the perception signaling.

[0160] In some embodiments, if the second indication information does not carry identification information of any perception signaling, it is considered that all perception signaling can be sent using the user plane protocol stack.

[0161] Step 1316: The first device receives third indication information, where the third indication information is used to indicate that the first device is rejected from sending perception signaling using the user plane protocol stack.

[0162] Correspondingly, the second device sends third indication information.

[0163] In some embodiments, the third indication information may be used to indicate that the first device is not allowed to use the user plane protocol stack to send perception signaling. Exemplarily, the second indication information may include identification information indicating that the first device is not allowed to use the user plane protocol stack to send perception signaling. If the second indication information indicates the perception signaling, the first device uses the control plane protocol stack to send the perception signaling. If the second indication information does not indicate the perception signaling, the first device uses the user plane protocol stack to send the perception signaling.

[0164] In some embodiments, if the third indication information does not carry any identification information of the perception signaling, it is considered that all perception signaling cannot be sent using the user plane protocol stack.

[0165] In some embodiments, if the third indication information is only used to indicate that part of the perception signaling is not allowed to use the user plane protocol stack to send the perception signaling, the third indication information may also include user plane protocol stack configuration information.

[0166] In some embodiments, the third indication information is used to configure the first timer. In some embodiments, the third indication information is used to configure the duration of the first timer.

[0167] In some embodiments, if the duration of the first timer is configured in the configuration information and / or the third indication information, the method further includes at least one of the following:

[0168] Upon receiving the third indication information or sending the request message, the first device starts the first timer;

[0169] During the first timer, the first device does not send a request message;

[0170] Upon receiving the configuration information, the first device stops the first timer;

[0171] After the first timer expires, the first device sends a request message.

[0172] In some embodiments, the configuration information may also configure a start time of the first timer. For example, the start time of the first timer configured in the configuration information may be when the third indication information is received or when the request message is sent.

[0173] In some embodiments, if the configuration information does not include configuration related to the first timer, the first device starts the first timer when receiving the third indication information.

[0174] In some embodiments, the first device does not send a request message during the first timer to avoid the first device sending request messages frequently and causing waste of transmission resources.

[0175] In some embodiments, after receiving the third indication information, the first device uses the control plane protocol stack to send perception signaling.

[0176] In some embodiments, after the first device receives the third indication information N times in a row, the first device uses the control plane protocol stack to send the perception signaling, where N is a positive integer. For example, N is 3. If the first device receives the third indication information after sending the request message three times in a row, the control plane protocol stack is used to send the perception signaling. If the first device receives the second indication information after sending the request message for the third time, the user plane protocol stack may be used to send the perception signaling based on the second indication information.

[0177] Through the above method, the first device can request the second device to use the user plane protocol stack to send perception signaling, so that the configuration information does not include the user plane protocol stack configuration information, and / or, when the perception signaling does not belong to the perception signaling type that allows the first device to use the user plane protocol stack for transmission, the first device can also use the user plane protocol stack to send perception signaling to avoid congestion of the control plane protocol stack.

[0178] In addition, after sending the request message, the first device may not receive the second indication information or the third indication information. For this purpose, an exemplary solution is also provided in the embodiment of the present application.

[0179] In some embodiments, if the first device receives neither the second indication information nor the third indication information, the control plane protocol stack is used to send the perception signaling.

[0180] In some embodiments, if the first device receives neither the second indication information nor the third indication information, the first device sends the request message again after the first time interval. In some embodiments, if the first device does not receive the second indication information and / or the third indication information for M consecutive times, the control plane protocol stack is used to send the perception signaling, where M is a positive integer.

[0181] In some embodiments, the first time interval may be predefined or preconfigured, may be indicated by the second device, or may depend on the implementation of the first device itself, and this application does not limit this. In some embodiments, the value of M may be predefined or preconfigured, may be indicated by the second device, or may depend on the implementation of the first device itself, and this application does not limit this.

[0182] Through the above method, the first device can determine how to send perception signaling even if it has not received the second indication information or the third indication information, thereby avoiding the terminal device from continuously sending request messages, causing delays in perception signaling transmission, and improving the stability of the communication system.

[0183] Method 2: Based on the first condition, use the user plane protocol stack to send perception signaling

[0184] 2.1 Based on the first condition, decide whether to use the user plane protocol stack to send perception signaling

[0185] In some embodiments, if the configuration information includes the first condition, the above step 1310 can be implemented as any one of the following steps 1317 to 1318.

[0186] Step 1317: When the perception signaling meets the first condition, the first device uses the user plane protocol stack to send the perception signaling.

[0187] Step 1318: When the perception signaling does not meet the first condition, the first device uses the control plane protocol stack to send the perception signaling.

[0188] In some embodiments, the first condition includes at least one of the following:

[0189] The type of the perception signaling is a perception signaling type that allows the first device to use a user plane protocol stack for transmission;

[0190] The data volume of the perception signaling is greater than or equal to the first threshold;

[0191] The QoS level of the perceived signaling complies with the QoS level condition information;

[0192] The reliability of the perception signaling is required to comply with the reliability level condition information.

[0193] In some embodiments, the first threshold value may be predefined or preconfigured, may be indicated by the second device, or may be determined by the first device based on its own implementation, which is not limited in this application.

[0194] In some embodiments, the QoS level condition information may include a QoS threshold. For example, when the QoS level of the perception signaling reaches the QoS threshold, the perception signaling is considered to meet the first condition and the perception signaling is sent using the user plane protocol stack.

[0195] In some embodiments, the reliability level condition information may include a reliability threshold. For example, when the reliability requirement of the perception signaling reaches the reliability threshold, the perception signaling is considered to meet the first condition, and the perception signaling is sent using the user plane protocol stack.

[0196] In some embodiments, the first condition may include one or more of the above.

[0197] In some embodiments, the first condition may also include other content, such as the priority of the perception signaling reaching the priority threshold. The embodiment of the present application is only an example of the first condition, and the first condition may also include other content.

[0198] In some embodiments, if the first device uses a user plane protocol stack to send perception signaling, the first device may send fourth indication information.

[0199] Through the above method, the first device independently determines whether to transmit the perception signaling using the user plane protocol stack or the control plane protocol stack based on the first condition. This dynamically switches between transmitting the perception signaling using the user plane protocol stack and transmitting the perception signaling using the control plane protocol stack, while reducing information exchange between the first and second devices and conserving transmission resources.

[0200] 2.2 Based on the first condition, decide whether to send a request message

[0201] In some embodiments, when the first condition is met, the first device uses a user plane protocol stack to send perception signaling.

[0202] In some embodiments, when the perception signaling does not meet the first condition, a request message is sent, where the request message is used to request the use of a user plane protocol stack to send the perception signaling.

[0203] In some embodiments, when the perception signaling does not meet the first condition and the third indication information is received, the first device uses the control plane protocol stack to send the perception signaling.

[0204] In some embodiments, when the perception signaling does not meet the first condition but receives the second indication information, the first device uses the user plane protocol stack to send the perception signaling.

[0205] Through the above method, the first device can combine the first condition and information interaction with the second device to realize dynamic switching between using the user plane protocol stack to transmit perception signaling and using the control plane protocol stack to transmit perception signaling, thereby avoiding congestion of the control plane protocol stack.

[0206] It should be noted that the above-mentioned method 1 and method 2 are merely examples of possible methods. The methods provided in the embodiments of the present application can also be combined to obtain other methods, and the combined methods should also fall within the scope of protection of the embodiments of the present application.

[0207] In the above method embodiments, the technical solution of the present application is described only from the perspective of the interaction between the first device and the second device. The above steps performed by the first device can be independently implemented as an information transmission method on the first device side, and the above steps performed by the second device can be independently implemented as an information transmission method on the second device side. In addition, the embodiments provided herein can be arbitrarily combined to form new embodiments, which are all within the scope of protection of this application.
