[0123] The specific implementation manners of the present application will be described below in conjunction with the drawings in the embodiments of the present application. However, the implementation manners of the present application can also include combinations of these embodiments without departing from the spirit or scope of the present application, such as using other embodiments and making structural changes. Therefore, the detailed description of the following embodiments should not be understood in a limiting sense. The terms used in the embodiment part of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

[0125] Figure 1 A possible, non-limiting system diagram is shown. As shown in Figure 1 , the communication system 1000 can include a wireless access network 100 and a core network 200. Optionally, the communication system 1000 can further include an Internet 300. The wireless access network 100 can include at least one wireless access network device (e.g., 110a and 110b in Figure 1 ), and at least one terminal (e.g., 120a-120j in Figure 1 ). The terminal is connected to the wireless access network device in a wireless manner, and the wireless access network device is connected to the core network in a wireless or wired manner. The core network device and the wireless access network device can be independent and different physical devices, or can be integrated into the same physical device with the functions of the core network device and the logical functions of the wireless access network device, or can be a physical device integrated with part of the functions of the core network device and part of the functions of the wireless access network device. The terminals can be connected to each other in a wired or wireless manner, and the wireless access network devices can be connected to each other in a wired or wireless manner. Figure 1 This is only a schematic diagram, and the communication system can further include other network devices, such as wireless relay devices and wireless backhaul devices, which are not shown in Figure 1 . Unless otherwise specified, the network devices in this application can include access network devices and / or core network devices.

[0126] The wireless access network device can be a base station, an evolved NodeB (eNodeB / eNB), a transmission reception point (TRP), a transmission point (TP), a next generation NodeB (gNB) or a next generation (NG)-eNB in a 5G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc. The wireless access network device can also be an open access network (O-RAN or ORAN) device, or a cloud radio access network (CRAN) device. The wireless access network device can also be a communication system integrating two or more of the above systems. The wireless access network device can be a macro base station (e.g., 110a in Figure 1 ), a micro base station or an indoor station (e.g., 110b in Figure 1 ), a relay node or a donor node, etc.

[0127] In addition, the wireless access network device can also be a module or unit that completes the function of the base station part, for example, can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. In different systems, the CU (or CU-CP and CU-UP), DU or RU can also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, the CU can also be referred to as an O-CU (open CU), the DU can also be referred to as an O-DU, the CU-CP can also be referred to as an O-CU-CP, the CU-UP can also be referred to as an O-CU-UP, and the RU can also be referred to as an O-RU. For the convenience of description, the CU, CU-CP, CU-UP, DU and RU are taken as examples for description in this application. Any one of the CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0128] Embodiments of the present application do not limit the specific technology and specific device form adopted by the wireless access network device. For the convenience of description, the wireless access network device will be referred to as the access network device hereinafter. It can be understood that the access network device can also be referred to as a communication apparatus. For example, the access network device can be understood as an apparatus with the function of the access network device. For example, the apparatus with the function of the access network device can be the access network device, or part of the elements in the access network device, such as the CU, the DU, etc. It can also be an apparatus capable of supporting the access network device to implement the function, such as a chip system, a hardware circuit, a software module, or a hardware circuit plus a software module, which can be installed in the access network device or can be used in matching with the access network device. In the embodiments of the present application, the chip system can be composed of a chip, or can include a chip and other discrete devices.

[0129] The terminal can also be referred to as a terminal device, a user equipment (UE), a mobile station, a mobile terminal, etc. The terminal can be widely applied to various scenarios, such as device-to-device (D2D) communication, vehicle-to-everything (V2X) communication, MTC, IoT, virtual reality, augmented reality, industrial control, automatic driving, remote medical treatment, smart power grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a mechanical arm, a smart home device, etc.

[0130] Embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal. It can be understood that the terminal can be referred to as a communication device. For example, the terminal can be understood as a device with terminal functions. For example, the device with terminal functions can be a terminal; it can also be a device capable of supporting the terminal to realize the function, such as a chip system, a hardware circuit, a software module, or a hardware circuit plus a software module, which can be installed in the terminal or can be used with the terminal.

[0131] Figure 2 An example diagram of an O-RAN system is shown. It should be understood that the O-RAN system can also include other components in addition to the components shown in Figure 3 , which are not specifically limited here. As shown in Figure 2 , the access network device can communicate with the core network (CN) through a backhaul link and can communicate with the terminal device through an air interface. For example, the access network device can include a baseband unit (BBU) and a radio unit (RU). The BBU includes at least one CU and at least one DU, and the CU and the DU can communicate through at least one midhaul link. The BBU communicates with the core network through the backhaul link, and the RU communicates with at least one terminal device through the air interface. The BBU communicates with at least one RU through a fronthaul link, and the BBU and the RU can be co-located or not co-located.

[0132] In some examples, the CU is a logical node that carries the radio resource control (RRC) layer, the service data adaptation protocol (SDAP) layer, the packet data convergence protocol (PDCP) layer, and other control functions of the access network device. The CU is connected to network nodes such as the core network through some interfaces, which can be E2 interfaces or the like. Optionally, the CU can have part of the functions of the core network. The CU (e.g., the PDCP layer and higher layers) is connected to the DU (e.g., the RLC layer and lower layers) through some interfaces, which can be F1 interfaces or the like. In some examples, these interfaces (e.g., F1 interfaces) can provide control plane (C-Plane) and user plane (U-Plane) functions (e.g., interface management, system information management, UE context management, RRC message transmission, etc.). F1AP is an application protocol for the F1 interface, which defines the signaling procedures of F1 in some examples. The F1 interface supports control plane F1-C and user plane F1-U.

[0133] In some examples, the CU can be split into a CU-CP (control unit-control plane) and a CU-UP (control unit-user plane), where the CU-CP is a logical node carrying the RRC layer and the PDCP-C (control plane part of PDCP) layer, used to implement the control plane function of the CU. The CU-CP can interact with a network element in the core network used to implement the control plane function. The network element in the core network used to implement the control plane function can be an access and mobility function network element, such as an access and mobility management function (AMF) in a 5G system. The AMF network element is used to be responsible for mobility management in a mobile network, such as location update of a terminal device, registration network of a terminal device, handover of a terminal device, etc. The CU-UP is a logical node carrying the SDAP layer and the PDCP-U (user plane part of PDCP) layer, used to implement the user plane function of the CU. The CU-UP can interact with a network element in the core network used to implement the user plane function. The network element in the core network used to implement the user plane function, for example, a user plane function (UPF) in a 5G system, is used to be responsible for forwarding and receiving data in a terminal device. The above configuration of the CU and the DU is only an example, and the CU and the DU can also be configured to have functions as needed. For example, the CU or the DU can be configured to have more protocol layer functions, or the CU or the DU can be configured to have partial processing functions of the protocol layer. For example, part of the functions of the RLC layer and the functions of the protocol layer above the RLC layer are arranged in the CU, and the remaining functions of the RLC layer and the functions of the protocol layer below the RLC layer are arranged in the DU. For another example, the functions of the CU or the DU can be divided according to the service type or other system requirements, for example, according to the delay, the functions that need to meet the delay requirement of the processing time are arranged in the DU, and the functions that do not need to meet the delay requirement are arranged in the CU.

[0134] In some examples, a DU is a logical node that hosts radio link control (RLC) layer, medium access control (MAC) layer, higher physical layer (higher PHY) layer, and other functions. In some examples, a DU can control at least one RU. The DU is connected with the RUs through some interfaces, which can be a fronthaul interface. In some examples, the higher physical layer includes parts of PHY layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.

[0135] In some examples, an RU is a logical node that hosts lower physical layer (Lower PHY) and radio frequency (RF) processing. In some examples, an RU can be a 3GPP transmission reception point (TRP) or a remote radio head (RRH) or other similar functional entity. In some examples, the lower physical layer includes parts of PHY processing, such as fast Fourier transform (FFT), inverse fast Fourier transformation (IFFT), digital beamforming and filtering, etc. An RU communicates with one or more UEs over a wireless link.

[0136] The DU and the RU can be co-located or not co-located. The DU and the RU exchange control plane information and user plane information via a lower-layer split CUS-plane (LLS-CUS) interface through a fronthaul link. The LLS-CUS can include a LLS-C interface and a LLS-U interface that provide control plane (C-Plane) and user plane (U-Plane), respectively. In some examples, the control plane (C-Plane) refers to real-time control between the DU and the RU. The DU and the RU exchange management information via a LLS-M interface of the fronthaul link, and the management plane (M-Plane) refers to non-real-time management operations between the DU and the RU.

[0137] The DU and the RU can cooperate to jointly implement the functions of the PHY layer. One DU can be connected with one or more RUs. The functions of the DU and the RU can be configured in multiple ways according to design. For example, the DU is configured to implement baseband functions, and the RU is configured to implement radio frequency functions. For another example, the DU is configured to implement high-layer functions in the PHY layer, and the RU is configured to implement low-layer functions in the PHY layer or implement the low-layer functions and radio frequency functions. The high-layer functions in the PHY layer can include a part of functions of the PHY layer that are closer to the MAC layer, and the low-layer functions in the PHY layer can include another part of functions of the PHY layer that are closer to the radio frequency side.

It can be known by those skilled in the art that the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems as the network architecture evolves and new service scenarios appear.

Any embodiment or design scheme described as "example" in the present application should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. Rather, the word "example" is intended to present the concept in a specific way. In the embodiments of the present application, "of", "corresponding / relevant" and "corresponding" can be used interchangeably at times, and it should be pointed out that when their differences are not emphasized, the meanings they express are consistent.

[0140] In the present application, "transmit (Tx / tx)" and "receive (Rx / rx)" represent the direction of signal transmission. For example, "transmit information to XX" can be understood as that the destination of the information is XX, and "transmit information" can include direct transmission or indirect transmission through other communication devices, communication apparatuses, units or modules. "Receive information from YY" can be understood as that the source of the information is YY, and "receive information" can include direct reception from YY or indirect reception from YY through other communication devices, communication apparatuses, units or modules. In addition, "transmit" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface. In other words, "transmit" or "receive" can be performed between devices, for example, transmitted or received between an access network device and a terminal through an air interface, or performed within a device, for example, transmitted or received between components, modules, chips, software modules or hardware modules within the device through a bus, wire or interface.

[0141] In the present application, "for indicating" can include direct indication and indirect indication. When describing that "information" is used for indicating A, it can include that the information directly indicates A or indirectly indicates A, and does not mean that A is necessarily carried in the information.

[0142] The information indicated by one information is referred to as to-be-indicated information. In the implementation process, there are many ways to indicate the to-be-indicated information, for example, but not limited to, the to-be-indicated information can be directly indicated, such as the to-be-indicated information itself or an index of the to-be-indicated information. The to-be-indicated information can also be indirectly indicated by indicating other information, where the other information and the to-be-indicated information have an association relationship. The to-be-indicated information can also be only indicated in part, and the other part of the to-be-indicated information is known or agreed in advance. For example, the indication of a specific information can also be realized by means of the arrangement order of each information agreed in advance (for example, a protocol), thereby reducing the indication overhead to a certain extent. At the same time, the common part of each information can be identified and uniformly indicated, so as to reduce the indication overhead caused by separately indicating the same information.

[0143] In addition, the specific indication manner can also be various existing indication manners, for example, but not limited to, the above-mentioned indication manners and various combinations thereof. The specific details of various indication manners can refer to the prior art, and will not be described herein. As can be seen from the above, for example, when multiple information of the same type needs to be indicated, the indication manners of different information can be different. In the implementation process, the required indication manner can be selected according to the specific needs, and the selected indication manner is not limited by the embodiments of the present application. In this way, the indication manner involved in the embodiments of the present application should be understood as covering various methods that can enable the to-be-indicated party to know the to-be-indicated information.

[0144] The to-be-indicated information can be sent together as a whole, or can be sent separately in multiple sub-information, and the sending period and / or sending occasion of the sub-information can be the same or different. The specific sending method is not limited in the present application. The sending period and / or sending occasion of the sub-information can be predefined, for example, predefined according to a protocol, or configured by the transmitting end device to the receiving device by sending configuration information. Taking the configuration of the access network device to the UE as an example, the configuration information can include, for example but not limited to, one or a combination of at least two of RRC signaling (or RRC message), MAC layer signaling and physical layer signaling. The MAC layer signaling includes, for example, MAC control element (CE). The physical layer signaling includes, for example, downlink control information (DCI) and other signaling or messages carried on the physical downlink control channel (PDCCH), and can also include downlink data (for example, data transmitted on the physical downlink shared channel (PDSCH)).

[0145] “Pre-set” or “pre-defined” or “pre-configured” can be implemented by pre-saving corresponding codes, tables or other means for indicating related information in devices (for example, including terminals and network devices), and can also be pre-defined in a protocol. The specific implementation method is not limited in the present application. The “saving” can mean saving in one or more memories. The one or more memories can be separately set, or integrated in the encoder or decoder, processor or communication device. The one or more memories can be part of separate setting, and part of integration in the decoder, processor or communication device. The type of memory can be any form of storage medium, which is not limited in the present application.

[0146] The following briefly describes the technical concepts involved in the present application:

[0147] 1. Perception object

[0148] The perception object can also be called perception target, perception point, unit point or reflection point, etc. In the present application, the perception object can be simply referred to as object. The perception object can be a static object, for example, surrounding environment physics, such as buildings, etc. The perception object can also be a dynamic object, for example, a drone, a car, etc., which is not limited in the present application.

[0149] 2、Sensing Reference Signal (SenRS / Se-RS)

[0150] Sensing Reference Signal or Sensing Signal is a signal used for sensing, which can refer to a signal transmitted by a transmitting end, or can also refer to a signal received by a receiving end (echo signal of a transmitted signal). In this application, it is not explicitly distinguished whether there is an echo signal, and the sensing reference signal can refer to one of the two. The sensing reference signal can be a signal that can be known by a receiving device (or receiving end, receiving terminal) for initial amplitude and phase. Alternatively, the sensing reference signal can be a reference signal, such as Se-RS, CSI-RS or sounding reference signal (SRS), and the initial amplitude and phase information of the sensing reference signal can be pre-configured to the receiving device by configuring a sequence or the like. The sensing reference signal can also be a data signal, and the receiving device can calculate the initial amplitude and phase of each data signal by data checking or other known modulation methods. The sensing reference signal can also be any signal that can be known by the receiving device for initial amplitude and phase. The present application does not limit the presentation form of the sensing reference signal.

[0151] 3、Sensing Result

[0152] The sensing result can also be referred to as sensing data or sensing information, and can also be referred to as information related to sensing. It refers to the relevant information of the sensing object obtained by the receiving device through the sensing reference signal. Exemplarily, the sensing result can be a distance-angle spectrum or a point cloud. The present application does not limit the specific form of the sensing result.

[0153] The distance-angle spectrum refers to a two-dimensional matrix or two-dimensional spectrum, for example, taking time delay as the horizontal coordinate and angle as the vertical coordinate, and the ratio of the energy / signal to interference plus noise ratio (SNR) of each point as the element in the distance-angle spectrum.

[0154] The point cloud or point cloud data is a data set of points in space, which can represent a three-dimensional shape or a sensing object. The position of each point in the point cloud is described by a set of Cartesian coordinates, and some may contain object reflection surface intensity, velocity and other information.

[0155] In the fifth generation mobile communication system (the 5 thIn the process of evolution from 5th generation mobile communication technology (5th-Generation, 5G) to 5G-advanced (5G-A), the communication and sensing integrated technology is considered as one of the key technologies to expand the service capability of mobile communication network. The core idea of this technology is to add sensing capability on the mobile communication network to build the capability of object detection, tracking and imaging, so as to make the communication and sensing capabilities coexist in one network, and even mutually beneficial.

[0156] The technical principle of sensing is different from that of communication. In communication, the sending device (or sending end, transmitting end) modulates information on radio waves and sends it to the receiving device, and the receiving device demodulates the signal carried on the radio waves to obtain information. In sensing, the sending device sends radio waves in a specific direction, and when the radio waves irradiate the surface of the object, reflected waves are formed, so that the receiving device receives and processes the reflected waves to obtain the position, speed and type of the object.

[0157] Sensing can be generally divided into two modes: single-station sensing and double-station sensing. In single-station sensing, the sending device and the receiving device of the sensing reference signal are the same device, which can be a terminal or a base station. From the perspective of the flow of the sensing reference signal, the sensing station not only sends the sensing reference signal, but also receives the signal reflected on the surface of the object (also known as echo signal), so the single-station sensing mode is also called self-transmitting and self-receiving mode, as shown in FIG. 1. For double-station sensing, the sending device and the receiving device of the sensing reference signal are two different devices, which can be terminals or base stations. From the perspective of the flow of the sensing reference signal, the signal reflected on the surface of the object after the sensing reference signal is sent by sensing station A is received by sensing station B, so the double-station sensing mode is also called A-transmitting and B-receiving mode, as shown in FIG. 2. Figure 3 Figure 4

[0158] The application scenarios of the present application include but are not limited to the communication and sensing integrated scenarios. Figure 5 As shown in FIG. 3, a possible and non-limiting communication and sensing integrated scenario is given, and the access network device and the terminal (such as UE1, UE2 and UE3) in the communication network can perform sensing on objects without communication function while performing communication.

[0159] As shown in FIG. 4, a possible and non-limiting communication and sensing integrated scenario is given, and the access network device and the terminal (such as UE1, UE2 and UE3) in the communication network can perform sensing on objects without communication function while performing communication. Figure 6 ​​The shown are various possible sensing mode diagrams. Among them, sensing mode (1) is a self-sending and self-receiving scenario of the base station, sensing mode (2) is a self-sending and self-receiving scenario of the UE, sensing mode (3) is a base station A sending and base station B receiving scenario, sensing mode (4) is a UE A sending and UE B receiving scenario, sensing mode (5) is a base station sending and UE receiving scenario, and sensing mode (6) is a UE sending and base station receiving scenario. Among them, "sending" here can be understood as "sending a sensing reference signal", and "receiving" can be understood as "receiving a backhaul signal". The present application can be applied to one or more sensing modes, and can also be applied to other sensing modes Figure 6 not limited by the present application. In the present application, the sensing mode can also be referred to as mode.

[0160] Among them, sensing mode (1) and sensing mode (2) are single-station sensing, and sensing mode (3) to sensing mode (6) are double-station sensing.

[0161] The following will be described in combination with Figure 7 , a schematic diagram of a communication system provided by an embodiment of the present application. Figure 7 The first communication device, the second communication device and the third communication device are shown. The first communication device can communicate with the second communication device and the third communication device respectively. The communication device involved in each embodiment of the present application can be understood as a device, a software module or a hardware module in the device, or a logical module, etc., and the specific limitation is not made. In addition, the communication device can also be replaced by a communication device, a network element, a device, an entity or a node, etc., and the specific limitation is not made to its name.

[0162] For example, the first communication device in the present application can send a sensing reference signal. The sensing reference signal becomes a backhaul signal after target reflection, scattering, refraction or diffraction, etc., and the sensing information can be obtained based on the backhaul signal. Optionally, the first communication device can also have sensing capability, for example, it can obtain sensing information based on sensing according to the received backhaul signal. For example, in a single-station sensing mode, the first communication device can send a sensing reference signal, and after the sensing reference signal is reflected, scattered, refracted or diffracted by the target, the first communication device receives the backhaul signal of the sensing reference signal, and then the sensing information can be obtained based on the backhaul signal. For another example, the first communication device can also obtain sensing information according to the backhaul signal of the sensing reference signal sent by other communication devices after receiving the backhaul signal.

[0163] In addition, the sensing information can also be obtained by a communication device other than the first communication device according to the echo signal of the sensing reference signal sent by the first communication device. For example, in a two-station sensing mode, the first communication device in the present application can send a sensing reference signal, and the echo signal of the sensing reference signal is received by a third communication device after the sensing reference signal is reflected, scattered, refracted or diffracted, etc. Then, the third communication device can obtain the sensing information based on the echo signal, and the third communication device can be a terminal device. Similarly, the fourth communication device can also receive the echo signal, and the fourth communication device can be an access network device. The first communication device can report the sensing information to the second communication device.

[0164] In a possible implementation, the first communication device is an access network device, or a component in the access network device, such as a chip or a chip system arranged in the access network device. In this implementation, the echo signal is received by a third communication device, such as a terminal device, or a component in the terminal device, such as a chip or a chip system arranged in the terminal device.

[0165] In another possible implementation, the configuration information of the sensing reference signal is requested by the second communication device from the first communication device, and the configuration information of the sensing reference signal is fed back by the first communication device to the second communication device. The second communication device is a core network element such as an SMF / SF, or a component in the core network element such as an SMF / SF, such as a chip or a chip system arranged in the core network element such as an SMF / SF.

[0166] In another possible implementation, the echo signal is received by a third communication device, and the first communication device and the fourth communication device are both access network devices, or components in the access network devices, such as chips or chip systems arranged in the access network devices. For example, the first communication device is a base station, and the fourth communication device is a micro station.

[0167] Optionally, if the first communication device is an access network device, the first communication device and / or the fourth communication device can include at least one TRP, or the first communication device can be arranged or associated with at least one TRP. The results of measuring the echo signal by different TRPs can be different.

[0168] It can be understood that the present application mainly considers the scenario in which the access network device sends the sensing reference signal.

[0169] In the present application, the second communication device in the present application can be configured to configure the transmission of the sensing reference signal and / or the reception of the echo signal. For example, the second communication device can be configured to configure the transmission resource of the sensing reference signal and / or the reception resource of the echo signal. Optionally, the second communication device can also have the ability to transmit the sensing information, and also have the ability to process (such as at least one of management, control or calculation) the sensing information.

[0170] The second communication device can be a core network element or a core network function or a core network entity, for example, the second communication device can be a sensing management function (SMF), a sensing mobile function (SMM), a sensing function (SF), a location management function (LMF) (also known as a positioning management device, a positioning management network element, a positioning server, a positioning center, a positioning network element, a positioning function network element, or a positioning management function, etc.), or a sensing management control (SMC) (also known as a control network element, an edge sensing function network element, an edge control network element, or an edge control node, without limiting the name thereof), or a module in these network elements, etc. Alternatively, the second communication device can also be a server (such as a third-party server) or a module (such as a software module or a hardware module) in the server, etc. The specific implementation form of the second communication device is not limited in the embodiments of the present application.

[0171] It can be understood that Figure 7 In the system architecture shown, the first communication device and the second communication device can be directly connected or indirectly connected. Direct connection can mean that the first communication device and the second communication device are connected through an interface or a link, that is, the interface or the link of the first communication device and the second communication device, that is, the first communication device does not need to be connected with the second communication device through other communication devices. It can also be said that in the case of direct connection, the information between the first communication device and the second communication device is directly transmitted between the two, without the forwarding of other communication devices. Indirect connection can mean that the first communication device and the second communication device are connected through other communication devices, and the information transmitted by the first communication device to the second communication device needs to be forwarded by other communication devices, and / or the information transmitted by the second communication device to the first communication device needs to be forwarded by other communication devices. For the scenario of indirect connection, Figure 7The other communication devices between the first communication device and the second communication device are not shown in the figure, and it should not be understood that the communication devices do not exist, i.e. it should not be understood that the first communication device and the second communication device can only be directly connected. In this application, the communication device between the first communication device (such as a base station) and the second communication device (such as SMF / SF), for example, AMF, is not specifically required.

[0172] Please refer to Figure 8 A schematic diagram of a communication system applicable to the embodiments of the present application. Figure 8 The terminal device (such as one or more terminal devices), RAN (including one or more access network devices) and some core network elements are illustrated. Figure 8 The illustrated core network elements include AMF and LMF. Figure 8 The SMF or SF is also illustrated, and optionally, the SMF or SF can also be deployed in the core network, i.e. belongs to the core network element.

[0173] As an example, Figure 8 The illustrated access network device can be an example of the first communication device, and the access network device can be an example of the third communication device. Figure 8 The SMF / SF involved can be an example of the second communication device.

[0174] The access network devices can communicate with each other through the Xn interface. The access network devices included in the access network can be the same type of access network devices, such as gNB or next generation (NG)-eNB (i.e. ng-eNB). The ng-eNB is a base station of long term evolution (LTE) technology, and the ng-eNB can include one or more transmission points (TPs). The gNB is a base station of NR, and the gNB can include one or more TRPs. The ng-eNB and the gNB can communicate with each other through the Xn interface. Alternatively, the access network devices included in the access network can be different types of access network devices. For example, some access network devices are ng-eNBs, and some other access network devices are gNBs.

[0175] The terminal device and the access network communicate through the Uu link, for example, the terminal device can communicate with the ng-eNB through the LTE-Uu, and communicate with the gNB through the NR-Uu link. The access network and the AMF communicate through the NG-C interface, the AMF is equivalent to the access network and the LMF communication, and the router of the access network and the SMF / SF. The AMF and the LMF communicate through the NLs (such as NL1) interface.

[0176] Optionally, Figure 8The SMF / SF and the LMF in the figure can be the same network element, or the SMF / SF and the LMF can be integrated together. In this case, the integration result of the LMF and the SMF can be an example of the second communication device.

[0177] Optionally, the SMF can be an architecture without separation of user plane and control plane. In actual application, the user plane and the control plane of the SMF can also be separated, and the SMF includes a sensing function-control (SF-C) and a sensing function-user (SF-U).

[0178] Figure 9 A schematic diagram of a communication system applicable to the embodiments of the present application is shown. As shown in the figure, the communication system includes terminal devices (such as one or more terminal devices), a RAN (such as one or more access network devices), an SMC, and an SMF / SF. The content of the access network device can refer to the content of the access network device discussed in Figure 9 The SMC is connected to the first access network device and the second access network device through an interface, respectively. The access network device can also be connected to different SMCs, respectively. Optionally, the SMF / SF can communicate with the SMC. Figure 8

[0179] Figure 9 The schematic access network device can be an example of the first communication device, and the terminal device can be an example of the third communication device. Figure 9 The SMF / SF involved can be an example of the second communication device, or Figure 9 The SMC involved can be an example of the second communication device.

[0180] Figure 9 The SMF shown in the figure is taken as an example of an implementation manner without separation of user plane and control plane. In actual application, the user plane and the control plane of the SMF can also be separated, and the SMF includes an SF-C and an SF-U. Similarly, the SMC can be without separation or with separation of user plane and control plane. If the SMC is separated, the SMC can be divided into an SM-C and an SM-U. The SM-C can communicate with the SF-C, and the SM-U can communicate with the SF-U.

[0181] The following takes an example in which the execution subject is the third communication device, and introduces the communication method provided by the present application in combination with the flow shown in Figure 10

[0182] As shown in the figure, the communication method can include the following steps: Figure 10

[0183] S1001: The third communication device receives first configuration information.​​​

[0184] The first configuration information includes a receiving configuration of one or more first sensing reference signals. In other words, the first configuration information can be used to configure the receiving of the echo signals of the one or more sensing reference signals.

[0185] In this application, the configuration information of the sensing reference signal can include the sending configuration and / or the receiving configuration, unless otherwise specified. The sending device of the sensing reference signal can send the sensing reference signal according to the sending configuration, and the receiving device of the sensing reference signal can receive the echo signal of the sensing reference signal according to the receiving configuration. The configuration information of the sensing reference signal can be queried, determined or configured by the access network device (such as the fourth communication device), wherein the fourth communication device can query, determine or configure the configuration information according to the request of the second communication device.

[0186] In S1001, the receiving configuration information of the first sensing reference signal can include the resource configuration of the first sensing reference signal, which can be used to determine the time-frequency resource for receiving the echo signal of the first sensing reference signal.

[0187] In S1001, the first configuration information is included in the RRC message or the NAS message, and the receiving configuration information of the first sensing reference signal includes the resource configuration of the first sensing reference signal. In other words, the first configuration information can obtain the receiving configuration of the sensing reference signal from the RRC message or the NAS message.

[0188] It can be understood that the RRC message is sent by the fourth communication device, which can be an access network device such as a base station, or a component such as a module or a chip in the access network device. The fourth communication device can be an access network device accessed by the third communication device.

[0189] The NAS message can be sent by the second communication device, which can be a core network element. The core network element can be, for example, an SMF / SF. The NAS message can be sent by the second communication device and forwarded to the third communication device by the access network device accessed by the third communication device.

[0190] The content of the configuration information of the sensing reference signal is introduced below. The sensing reference signal herein can include the first sensing reference signal and / or the second sensing reference signal, and can also include other sensing reference signals involved in this application, which are not specifically limited.

[0191] In this application, the configuration information of the sensing reference signal can include one or more of the resource configuration of the sensing reference signal, the sensing mode information, the transceiving mode information or the sensing transaction ID.

[0192] The resource configuration, the sensing mode information, the transceiving mode information, and the sensing procedure identifier are introduced below.

[0193] A1, The resource configuration can also be referred to as a time-frequency configuration, which can be used to indicate or configure a time-frequency resource of the sensing reference signal. The time-frequency resource can be a transmission resource and / or a reception resource of the sensing reference signal. It can be considered that a transmission device of the sensing reference signal can transmit a signal according to the resource configuration, and / or a reception device of the sensing reference signal can receive a signal according to the resource configuration.

[0194] Specifically, the resource configuration can include a frequency configuration and a time configuration. The frequency configuration includes, for example, configuration parameters such as a sub-carrier spacing (SCS) of the sensing reference signal, a cyclic prefix (CP), a bandwidth, a frequency start position, or a frequency hopping configuration. The time configuration includes, for example, configuration parameters such as a time domain start position, a duration, or a period.

[0195] A2, The sensing mode information can be used to indicate or configure a sensing mode corresponding to the sensing reference signal. The sensing mode can be used to identify the relationship between the transmission device and the reception device of the sensing reference signal, such as indicating whether the transmission device and the reception device are the same device, or indicating whether the transmission device and / or the reception device is a terminal device or a base station. Specifically, the sensing mode can be any of the modes shown in Figure 6 , or other modes, which are not specifically limited.

[0196] As an example, the sensing mode information takes a value of any one of 1 to 3. The sensing mode information can indicate the sensing mode in the form of enumeration, index, or bit string.

[0197] For example, the enumeration indication mode can be: the sensing mode information takes a value of “mode1” to “mode3”, representing the sensing mode as mode 1 to mode 3, respectively. For another example, the index indication mode can be: the sensing mode information takes a value of “Index1” to “Index3”, representing the sensing mode as mode 1 to mode 3, respectively. For another example, the bit string indication mode can be: the sensing mode information takes a value of 00, 01, and 10, representing the sensing mode as mode 1 to mode 3, respectively.

[0198] It can be understood that mode 1 to mode 3 can represent Figure 6 , respectively. For example, mode 1 to mode 3 represent sensing mode (1), sensing mode (3), and sensing mode (5), respectively.

[0199] It can also be understood that the configuration information of the sensing reference signal of the sensing mode of the plurality of third communication devices can be indicated in the first configuration information. Therefore, the sensing mode of the configuration information of the sensing reference signal can be additionally indicated in the first configuration information.

[0200] A3, the transceiving mode information, also known as device function information, can be used to indicate or configure the configuration information of the sensing reference signal as transmission configuration information or reception configuration information. If the configuration information is transmission configuration information, the communication device corresponding to the reception configuration information can transmit the sensing reference signal according to the configuration information. If the configuration information is reception configuration information, the communication device corresponding to the reception configuration information can receive the echo signal of the sensing reference signal according to the configuration information.

[0201] An implementation of the transceiving mode information is, for example, that the first value represents transmission and the second value represents reception. The first value and the second value can occupy the same field, information element or bit (or bit string). For example, the transceiving mode information occupies 1 bit, wherein the first value representing transmission can be 0 and the second value representing reception can be 1, or the first value can be 1 and the second value can be 0.

[0202] In addition, the transceiving mode information can include the identification of the receiving device and / or the identification of the transmitting device to indicate the receiving device and / or the transmitting device to which the configuration information is applicable.

[0203] For example, the transceiving mode information can be a combination of transceiving indication and device identification (device-id). For example, the transceiving indication can be the first value or the second value, and the first value and the second value represent transmission and reception respectively. The identification can be, for example, the identification of the terminal device. For example, (0, device-id#1) represents that the identification of the transmitting device is device-id#1, and (1, device-id#2) represents that the identification of the receiving device is device-id#2.

[0204] For example, the identity of the transmitting device (denoted as txdevice-id) and the identity of the receiving device (denoted as rxdevice-id) can be paired. For example, (txdevice-id#1, rxdevice-id#1) and (txdevice-id#2, rxdevice-id#2) represent that the identity of the transmitting device of the sensing reference signal #1 is txdevice-id#1, and the identity of the receiving device of the sensing reference signal is rxdevice-id#1. For another example, (txdevice-id#1, txdevice-id#2) and (rxdevice-id#1, rxdevice-id#2) represent that the identity of the transmitting device of the sensing reference signal #1 is txdevice-id#1, and the identity of the transmitting device of the sensing reference signal #1 is rxdevice-id#1, in addition, the identity of the transmitting device of the sensing reference signal #2 is txdevice-id#2, and the identity of the transmitting device of the sensing reference signal #2 is rxdevice-id#2.

[0205] In addition, in the above examples, the identity of the device can also be represented by an index. For example, index 1 represents device-id#1. The mapping relationship between the index and the identity of the device can be pre-configured, for example, the mapping relationship can be broadcast by the base station through a broadcast message, and the terminal device can learn the index corresponding to the identity of the device through the broadcast message.

[0206] For example, for the first sensing reference signal, the transceiving mode information in the receiving configuration information of the first sensing reference signal can include first indication information, which is used to indicate that the third communication device is the receiving device of the first sensing reference signal. For example, the first indication information includes the identity of the receiving device, which is the identity of the device of the third communication device. For another example, in the case that the first configuration information also includes the configuration information of the second sensing reference signal, for the second sensing reference signal, the transceiving mode information can include second indication information, which is used to indicate that the third communication device is the transmitting device, to indicate that the second sensing reference signal is the sensing reference signal transmitted by the third communication device. For another example, in the receiving configuration information of the first sensing reference signal, the transceiving mode information can include third indication information, which is used to indicate that the first communication device is the transmitting device of the first sensing reference signal.

[0207] Optionally, in the case that the first configuration information includes the configuration information of multiple sensing reference signals, the transceiving mode information of the configuration information of multiple sensing reference signals can be carried in the first configuration information by enumeration or bitmap, etc.

[0208] For example, the first configuration information can be a sensing reference signal configuration (SenRS-Config). Wherein, for receiving configuration information, the SenRS-Config can be SenRS-ConfigRx, and the first transmission unit can be SenRS-ConfigRx configuration accordingly. For sending configuration information, the SenRS-Config can be SenRS-ConfigTx, and the first transmission unit can be SenRS-ConfigTx configuration accordingly. An exemplary pseudo code for enumerating the sensing mode information of the sensing reference signal in the SenRS-Config is as follows:

[0209]

[0210] A4, a sensing procedure identifier, used to indicate the sensing procedure to which the sensing reference signal belongs. For example, the communication device can determine the sensing procedure to which the configuration information applies according to the sensing procedure identifier. Different sensing procedure identifiers correspond to different sensing procedures. For the same terminal device, the configuration information in different sensing procedures can be different.

[0211] As an example, any sensing procedure identifier can correspond to one or more pairs of sending devices and receiving devices, or one or more sensing reference signals of one or more pairs of sending devices and receiving devices. In addition, any sensing procedure identifier can also be considered to correspond to a certain time domain resource range and / or frequency domain resource range.

[0212] For example, the first configuration information contains the configuration information of the first sensing reference signal, and the first configuration information can contain a first identifier, which is the identifier of the sensing procedure to which the first sensing reference signal belongs. For another example, if the first configuration information also contains the configuration information of the second sensing reference signal, the first configuration information can contain a second identifier, which is the identifier of the sensing procedure to which the second sensing reference signal belongs.

[0213] A5, in addition to A1 to A4, the configuration information of any sensing reference signal can also contain one or more of the following parameters:

[0214] (1) Frequency layer (Freqlayer)

[0215] Wherein, the frequency layer can be used to indicate the frequency layer to which the sensing reference signal corresponds. For example, the frequency layer transmission can be the identifier, spectrum information or index of the frequency layer to which the sensing reference signal corresponds.

[0216] In this application, if the same information, message or information element contains configuration information of multiple sensing reference signals, the frequency layer of each sensing reference signal can be indicated by enumerating the identifier of the frequency layer or by a bit map (bitmap) scheme, etc.

[0217] Optionally, the frequency layer parameter can also not be carried in the configuration information, but the frequency layer is indicated by other messages or signaling. For example, the frequency can be pre-configured or defined.

[0218] (2) TRP information

[0219] The TRP information can be used to indicate the TRP corresponding to the sensing reference signal. For example, the TRP information can be the identifier or index of the TRP corresponding to the sensing reference signal.

[0220] In this application, if the same information, message or information element contains configuration information of multiple sensing reference signals, the TRP information of the multiple sensing reference signals can be indicated by enumerating the identifiers of the frequency layers or by a bit map scheme.

[0221] Optionally, the TRP information can also not be carried in the configuration information, but the TRP information is indicated by other messages or signaling. For example, the TRP information can be pre-configured or defined.

[0222] (3) Resource mapping (resourceMapping) configuration, such as containing the number of continuous symbols, frequency interval or quasi coordinated-location (QCL) information and other parameters.

[0223] Optionally, the resource mapping configuration can also be considered to belong to the resource configuration.

[0224] (4) Transmission combination configuration, which can be used to configure the frequency domain resource combination mode.

[0225] For example, the transmission combination configuration includes the parameter frequency interval (transmissionComb). For example, transmissionComb = n, n is a positive integer, for example, n = 2, 4, 6, 8, …, transmissionComb is used to indicate the density of the sensing reference signal, that is, the frequency interval, that is, the sensing reference signal is transmitted every n subcarriers.

[0226] For another example, the transmission combination configuration includes the parameter subcarrier offset (combOffset). combOffset is a positive integer less than or equal to n-1, and n is the frequency interval. For example, if n = 2 and combOffset = 0, it means that the sensing reference signal is mapped to the 1st subcarrier, and the sensing reference signal is transmitted every 2 subcarriers after the 1st subcarrier; if n = 2 and combOffset = 1, it means that the sensing reference signal is mapped to the 2nd subcarrier, and the sensing reference signal is transmitted every 2 subcarriers after the 2nd subcarrier

[0227] For example, transmission combination configurations include parameter cyclic shift.

[0228] (5) Antenna and spatial configuration, including parameters such as port index (PortIndex) and spatial relationship information (spatialRelationInf).

[0229] Optionally, the configuration information of the sensing reference signal can be carried in the SenRS Configuration (SenRS-Config) message or information cell.

[0230] It is understood that at least two of the resource configuration, sensing mode information, transmit / receive mode information, and sensing process identifier in the configuration information of the first sensing reference signal can be carried in the same or different transmission units or sub-transmission units, without specific limitations.

[0231] It can also be understood that, for the same sensing reference signal, the TRP information in the transmit configuration information can be different from the TRP information in the receive configuration information, while other configurations in the transmit and receive configuration information can be the same. For example, the resource configuration in the transmit configuration information and the resource configuration in the receive configuration information of the same sensing reference signal can be the same.

[0232] S1002: The third communication device receives the echo signal of the first sensing reference signal according to the receiving configuration information of the first sensing reference signal.

[0233] For example, the third communication device determines the time-frequency resources for receiving the echo signal based on the resource configuration in the receiving configuration information of the first sensing reference signal, and detects the echo signal based on the time-frequency resources.

[0234] S1003: The third communication device measures based on the echo signal to obtain sensing information.

[0235] This sensing information can be understood as the sensing result. For example, the receiving device of the third sensing reference signal can receive the echo signal of the first sensing reference signal and obtain the sensing result by detecting the echo signal.

[0236] based on Figure 10 As shown in the process, the terminal device can receive the reception configuration information of the sensing reference signal through RRC messages or NAS messages, receive the echo signal of the sensing reference signal according to the reception configuration information of the sensing reference signal, and perform sensing detection based on the echo signal.

[0237] It can be understood that if the receiving device of the first sensing reference signal is the access network device, the receiving configuration information of the first sensing reference signal from the second communication apparatus or the fourth communication apparatus can also be received by the fourth communication apparatus in the present application. The receiving configuration information of the first sensing reference signal can refer to the introduction in S1001, and the difference is that the receiving configuration information of the first sensing reference signal received by the fourth communication apparatus is not carried in the RRC message. For example, the receiving configuration information of the first sensing reference signal received by the fourth communication apparatus can be carried in the NAS message or other messages transmitted between access network devices.

[0238] It can also be understood that the present application does not exclude that the third communication apparatus, the first communication apparatus, the fourth communication apparatus or multiple communication apparatuses in the fourth communication apparatus receive the echo signal of the same first sensing reference signal and obtain the sensing information by measuring the echo signal.

[0239] The possible structure of the first configuration information and / or the configuration information of the first sensing reference signal will be introduced below.

[0240] In the present application, the configuration information of the first sensing reference signal can be carried in the first transmission unit, that is, the configuration information of the first sensing reference signal can be transmitted through the first transmission unit. The first transmission unit can be carried in the RRC message or the NAS message. Among them, the first transmission unit can be understood as a transmission unit in the RRC message for carrying the first configuration information, or understood as a transmission unit in the NAS message for carrying the first configuration information. The transmission unit in the RRC message for carrying the first configuration information and the transmission unit in the NAS message for carrying the first configuration information are deployed in the same message.

[0241] Among them, the RRC message can be sent by the first communication apparatus to the third communication apparatus, and the NAS message can be sent by the second communication apparatus to the first communication apparatus. It can be considered that the first transmission unit is the first configuration information. It can also be considered that the first transmission unit is a transmission unit containing the first configuration information, that is, it is not limited whether the first transmission unit carries information other than the first configuration information.

[0242] The first transmission unit can be a transmission unit for transmitting sensing-related information. It can also be said that the first transmission unit is a transmission unit dedicated to transmitting sensing-related information. Specifically, the sensing-related information can also be referred to as sensing information, and can specifically be sensing-related configuration information. The sensing-related configuration information can also be referred to as sensing configuration information, which can be, for example, configuration information of a sensing reference signal or other configuration information, etc. That is, the first transmission unit can be a transmission unit dedicated to transmitting sensing information, or in other words, the first transmission unit is dedicated to providing sensing information (or sensing-related information). The first transmission unit is, for example, a message for providing sensing information or an information element for providing sensing information. It can also be said that the first transmission unit can be a transmission unit dedicated to transmitting configuration information of a sensing reference signal (or other sensing-related configuration information), or in other words, the first transmission unit is dedicated to providing sensing reference signal configuration (or sensing-related configuration). The first transmission unit is, for example, a message or an information element for providing sensing reference signal configuration, such as a ProvideSenRSConfiguration message or a ProvideSenRSConfiguration information element. Specifically, for receiving configuration information, the ProvideSenRSConfiguration can be ProvideSenRSConfigurationRx, and accordingly, the first transmission unit can be a ProvideSenRSConfigurationRx configuration. For transmitting configuration information, the ProvideSenRSConfiguration can be ProvideSenRSConfigurationTx, and accordingly, the first transmission unit can be a ProvideSenRSConfigurationTx configuration.

[0243] In a possible implementation, if the first configuration information is carried in an RRC message, the first configuration information can be SenRS-Config, and the first transmission unit can be a SenRS-Config configuration. If the first configuration information is carried in an NAS message, the first configuration information can be ProvideSenRSConfiguration, and the first transmission unit can be a ProvideSenRSConfiguration configuration.

[0244] In the present application, the communication device (such as the second communication device or the first communication device) will use the first transmission unit to transmit the sensing information by default when transmitting the sensing information. For example, the first transmission unit can be predefined or preconfigured for transmitting sensing-related information. For example, the first transmission unit can be a transmission unit predefined by a protocol for transmitting sensing information or configuration information of the sensing reference signal. The configuration information of the first sensing reference signal discussed above can be taken as a specific example of the sensing information (or the configuration information of the sensing reference signal).

[0245] In one possible implementation, for example Figure 11 As shown in (1), the configuration information of the first sensing reference signal (or the first transmission unit) can include SenRSConfiguration configuration, sensing mode configuration, and device identification configuration. The SenRSConfiguration configuration can be used to carry the resource configuration of the sensing reference signal. The sensing mode configuration can be used to carry the sensing mode information. The device identification configuration can be used to carry the identification of the transmitting device and / or the identification of the receiving device. Optionally, the configuration information of the first sensing reference signal (or the first transmission unit) can further include one or more IEs for carrying the sensing procedure identification and other parameters, which are not shown in the figure.

[0246] Specifically, the SenRSConfiguration configuration can include one or more sub-units or sub-configurations such as SenRSConfigurationPerFreq configuration, SenRSConfigurationPerTRP configuration, or SenRSConfigurationSet-Item configuration. The SenRSConfigurationPerFreq configuration can be used to indicate the frequency layer to which the first sensing reference signal is applicable. The SenRSConfigurationPerTRP configuration can be used to indicate the TRP to which the first sensing reference signal is applicable. The SenRSConfigurationSet-Item configuration is used for the carrying resource configuration to which the first sensing reference signal is applicable.

[0247] Based on Figure 11 As shown in (1), the configuration information of the first sensing reference signal (or the first transmission unit) can include SenRSConfiguration configuration, sensing mode configuration, and device identification configuration. The SenRSConfiguration configuration can be used to carry the resource configuration of the sensing reference signal. The sensing mode configuration can be used to carry the sensing mode information. The device identification configuration can be used to carry the identification of the transmitting device and / or the identification of the receiving device. Optionally, the configuration information of the first sensing reference signal (or the first transmission unit) can further include one or more IEs for carrying the sensing procedure identification and other parameters, which are not shown in the figure.

[0248] In another possible implementation, for example Figure 11As shown in FIG. 2, the configuration information of the first sensing reference signal can be carried in SenRS-ConfigA configuration. SenRS-ConfigA can be a configuration for carrying the configuration information of the sensing reference signal, including the reception configuration information of the first sensing reference signal.

[0249] As shown in FIG. 2, the configuration information of the first sensing reference signal can be carried in SenRS-ConfigA configuration. SenRS-ConfigA can be a configuration for carrying the configuration information of the sensing reference signal, including the reception configuration information of the first sensing reference signal. Figure 11 As shown in FIG. 2, the configuration information of the first sensing reference signal can be carried in SenRS-ConfigA configuration. SenRS-ConfigA can be a configuration for carrying the configuration information of the sensing reference signal, including the reception configuration information of the first sensing reference signal.

[0250] It can be considered that the SenRS-ResourceSet configuration can be used to indicate the configuration information of one or more sensing reference signals from the configuration information of one or more sensing reference signals in one or more SenRS-Resource configurations as the configuration information of the sensing reference signal configured this time.

[0251] As an example, the sensing reference signal resource configuration parameter can include the configuration information of the sensing reference signal resource granularity. For example, the sensing reference signal resource configuration parameter includes the resource identifier (SenRS-ResourceID) of the sensing reference signal, the resource type (resourceType), the time-frequency domain configuration, the parameter combination configuration, or the antenna and spatial configuration, etc.

[0252] Among them, the resource identifier can be used to mark the configuration information of each sensing reference signal. The resource type can be used to indicate the resource type of each sensing reference signal configuration information. Specifically, the resource type can represent that the configuration information of the sensing reference signal is periodic configuration, semi-periodic configuration or aperiodic configuration, etc.

[0253] The SenRS-ResourceSet configuration can include the sensing reference signal resource set identifier (SenRS-ResourceSetID), the resource set type (resourceSetType), and the identification list of the sensing reference signal resources contained in the sensing reference signal resource set (SenRS-ResourceIdList).

[0254] The perception reference signal resource set identifier can be used to mark one SenRS-ResourceSet configuration. The resource set type can be used to indicate that the resource set type is periodic configuration, aperiodic configuration or semi-periodic configuration. The identification list of the perception reference signal resource can contain one or more SenRS-ResourceID, which is used to indicate the configuration information of one or more perception reference signals.

[0255] Based on Figure 11 In the structure shown in (2), an exemplary pseudo code of SenRS-ConfigA configuration is as follows:

[0256]

[0257] In another possible implementation, the configuration information of the first perception reference signal (or the first transmission unit) can be ProvideSenRSConfigurationA configuration. The ProvideSenRSConfigurationA configuration can be specifically an IE used to carry the configuration information of the perception reference signal, including the reception configuration information of the first perception reference signal.

[0258] Optionally, the ProvideSenRSConfigurationA configuration can adopt the structure shown in (1). Figure 11 For example, the ProvideSenRSConfigurationA configuration contains the SenRSConfiguration configuration, the perception mode configuration and the device identification configuration shown in (1). Figure 11

[0259] In addition, the ProvideSenRSConfigurationA configuration can also adopt the structure shown in (3). Figure 11 For example, the ProvideSenRSConfigurationA configuration can contain the perception reference signal assistance data (SenRS-AssistanceData) configuration and the selected perception reference signal index list (Selected-SenRS-IndexList) configuration.

[0260] The SenRS-AssistanceData configuration can contain the configuration information of multiple perception reference signals, such as the configuration information of multiple frequency layers, the reference signal configuration of multiple TRPs, the frequency configuration, the time configuration, the resource mapping configuration and the perception reference signal identification.

[0261] ​Correspondingly, the Selected-SenRS-IndexList configuration can contain the selected reference signal configuration, such as by carrying the selected frequency layer index, the selected TRP index, the selected resource index, etc., to indicate the configuration information of one or more selected sensing reference signals in the SenRS-AssistanceData configuration. Among them, the resource index is, for example, a resource index (ResourceIndex), a resource identifier (ResourceID), a resource set index (ResourceSetIndex), or a resource set identifier (ResourceSetID).

[0262] Based on this implementation, the configuration of different frequency, different TRP and different time-frequency resources can be provided through the sensing reference signal assistance data configuration, and one or more sensing reference signal resource configurations can be selected from the configuration through the selected sensing reference signal index list configuration to indicate the transmission or reception of signals in the corresponding resource.

[0263] Based on Figure 11 In the structure shown in (3), an exemplary pseudo code of the ProvideSenRSConfigurationA configuration is as follows:

[0264]

[0265] In the above pseudo code, SenRS-AssistanceData can be used to define specific time-frequency resources, such as configurations including the location, period, resource mapping method, resource identifier, etc. of time-frequency resources of different frequency layers and different TRPs, as follows:

[0266]

[0267] In addition, in the above pseudo code, Selected-SenRS-IndexList can be used to indicate the reception and transmission of sensing reference signals on which block of defined resources, and can contain parameters such as the frequency layer, TRP or resource identifier of the specific selected time-frequency resource. For example, Selected-SenRS-IndexList can be implemented through the following pseudo code:

[0268]

[0269] It can be understood that if the configuration information of the first sensing reference signal is carried in the RRC message, the configuration information of the first sensing reference signal can contain the structure shown in (2). Figure 11 If the configuration information of the first sensing reference signal is carried in the NAS message, the configuration information of the first sensing reference signal can contain the structure shown in (1) or (3). Figure 11 ​

[0270] In a possible embodiment, the configuration information of the sensing reference signal can be carried in a same RRC message or a same NAS message as the configuration information of other types of reference signals. The other types of reference signals include, but are not limited to, PRS, SRS, or CSI-RS. The configuration information of the sensing reference signal herein can include the configuration information of the first sensing reference signal or the configuration information of the second sensing reference signal.

[0271] It can be understood that the transmission configuration information of the sensing reference signal can be carried in a same RRC message as SRS-Config. For example, the transmission configuration information of the first sensing reference signal and / or the transmission configuration information of the second sensing reference signal can be carried in a same RRC message as SRS-Config.

[0272] The reception configuration information of the sensing reference signal (e.g., the reception configuration information of the first sensing reference signal) can be carried in a same RRC message as CSI-RS configuration. The CSI-RS configuration can be CSI-MeasConfig. For example, the transmission configuration information of the first sensing reference signal and / or the reception configuration information of the second sensing reference signal can be carried in a same RRC message as CSI-MeasConfig.

[0273] In addition, the first configuration information (e.g., the reception configuration information of the first sensing reference signal) can be carried in a same NAS message as PRS configuration.

[0274] Taking the transmission configuration information of the first sensing reference signal as SenRS-ConfigA, if SenRS-ConfigA is carried in a same RRC message as CSI-MeasConfig, SenRS-ConfigA and CSI-MeasConfig can satisfy the following positional relationship:

[0275] Positional relationship B1, embedded: a first transmission unit for carrying SenRS-ConfigA is embedded in a second transmission unit for carrying CSI-MeasConfig, as shown in (1) in FIG. 13. Correspondingly, the first communication apparatus can send CSI-MeasConfig to the third communication apparatus, and the CSI-MeasConfig can include SenRS-ConfigA. Positional relationship B1 can also be described as: SenRS-ConfigA is included in a sub-transmission unit of CSI-MeasConfig. The second transmission unit can be considered as a transmission unit dedicated for transmitting CSI-MeasConfig. Figure 12

[0276] ​The first transmission unit is, for example, a SenRS-ConfigA configuration, and the second transmission unit is, for example, a CSI-MeasConfig configuration.

[0277] Position relationship B2, juxtaposition: in an RRC message, the first transmission unit for carrying the SenRS-ConfigA and the second transmission unit for carrying the CSI-MeasConfig are located in two transmission units in juxtaposition, as shown in Figure 12 Correspondingly, the first communication device can send the CSI-MeasConfig and the SenRS-ConfigA to the third communication device. The position relationship B2 can also be described as: the SenRS-ConfigA and the CSI-MeasConfig are two transmission units of the same level, and the two transmission units do not contain each other, and the two transmission units are located in the same IE or message or information.

[0278] The first transmission unit is, for example, a SenRS-ConfigA configuration, and the second transmission unit is, for example, a CSI-MeasConfig configuration.

[0279] Position relationship B3, combination: in an RRC message, the SenRS-ConfigA and the CSI-MeasConfig can be carried in the same transmission unit (for example, a third transmission unit), that is, the SenRS-ConfigA and the CSI-MeasConfig can be combined as a transmission unit, as shown in Figure 12 It can be considered that the SenRS-ConfigA and / or the CSI-MeasConfig are carried in a sub-transmission unit of the third transmission unit. Correspondingly, the first communication device can send the third transmission unit to the third communication device, and the third transmission unit contains the SenRS-ConfigA and the CSI-MeasConfig. Figure 12 In the embodiment, the third transmission unit is exemplarily represented as an ISACRS-Config configuration, and the third transmission unit can also have other names.

[0280] In addition, the ProvideSenRSConfigurationA configuration can be carried in the NAS message, which can be used to carry the reception configuration information of the sensing reference signal (e.g., the first sensing reference signal), denoted as ProvideSenRSConfigurationA. The first configuration information can include the ProvideSenRSConfigurationA. In addition, the ProvideAssistanceData configuration can also be carried in the NAS message. The ProvideAssistanceData configuration can be used to carry the PRS configuration, which can be referred to the definition in the LTE positioning protocol (LPP).

[0281] The ProvideSenRSConfigurationA configuration and the ProvideAssistanceData configuration can satisfy the following location relationship:

[0282] Location relationship C1, embedded: in the NAS message, the ProvideSenRSConfigurationA configuration is embedded in the ProvideAssistanceData configuration, as shown in number (1) in Figure 14 Accordingly, the first communication device can send the ProvideAssistanceData configuration to the third communication device, and the ProvideAssistanceData configuration can include the ProvideSenRSConfigurationA configuration. The location relationship C1 can also be described as: the ProvideSenRSConfigurationA configuration is a sub-transmission unit of the ProvideAssistanceData configuration.

[0283] As an example of the location relationship C1, the ProvideISACAAssistanceData including the ProvideSenRSConfigurationA configuration and the ProvideAssistanceData configuration can be implemented by the following pseudo code:

[0284]

[0285] Location relationship C2, parallel: in the NAS message, the ProvideSenRSConfigurationA configuration and the ProvideAssistanceData configuration are located in two parallel transmission units, as shown in number (2) in Figure 14The position relationship C2 is shown in the middle number (2). Correspondingly, the first communication device can send the ProvideAssistanceData configuration to the third communication device, and send the ProvideSenRSConfigurationA configuration. The position relationship C2 can also be described as: the ProvideAssistanceData configuration and the ProvideSenRSConfigurationA configuration are the same level transmission units, the same transmission units are not contained in each other, and are located in the same IE or message or information.

[0286] The position relationship C3 is shown in the middle number (3). The ProvideAssistanceData configuration and the ProvideSenRSConfigurationA configuration can be combined as a transmission unit, that is, the ProvideAssistanceData configuration and the ProvideSenRSConfigurationA configuration can be combined as a transmission unit. Figure 14 The position relationship C3 is shown in the middle number (3). The ProvideAssistanceData configuration and the ProvideSenRSConfigurationA configuration can be combined as a transmission unit, that is, the ProvideAssistanceData configuration and the ProvideSenRSConfigurationA configuration can be combined as a transmission unit. Figure 12 The third transmission unit is exemplarily represented as the ProvideISACAAssistanceData configuration, and the third transmission unit can also have other names.

[0287] The above ProvideSenRSConfigurationA configuration can be considered as the first transmission unit for carrying the configuration information of the sensing reference signal in the NAS message. The ProvideAssistanceData configuration can be considered as the second transmission unit for carrying the PRS configuration in the NAS message.

[0288] In a possible embodiment, for the scenario that the second communication device sends the receiving configuration information of the first sensing reference signal to the fourth communication device (such as an access network device), the second communication device can send the receiving configuration information to the second communication device through the NAS message.

[0289] The NAS message can also include PRS configuration request information and / or PRS response information. The PRS configuration request information can be used to request the fourth communication device to determine the PRS configuration. The PRS response information can be the response information of the PRS configuration request information. The PRS response information can include the PRS configuration, which can be defined in the LTE positioning protocol.

[0290] As shown in Figure 13 , the PRS configuration request (PRSConfigurationRequest) is used as the PRS configuration request information, the PRS configuration response (PRSConfigurationResponse) is used as the PRS response information, and the ProvideSenRSConfigurationB is used as the configuration information of the sensing reference signal of the fourth communication device in the NAS message. The position relationship between the configuration information of the sensing reference signal of the fourth communication device in the NAS message (such as the reception configuration information), the PRS configuration request information, and / or the PRS response information is introduced. The PRSConfigurationRequest and / or the PRSConfigurationResponse can be referred to the description in the NR positioning protocol A (NRPPa).

[0291] As shown in Figure 13 , the PRSConfigurationRequest configuration and / or the PRSConfigurationResponse configuration can be parallel to the ProvideSenRSConfigurationB configuration. That is, the PRSConfigurationRequest configuration and / or the PRSConfigurationResponse configuration and the ProvideSenRSConfigurationB configuration can be two transmission units with the same level in the NAS message.

[0292] In a possible embodiment, the second communication device sends the reception configuration information to the second communication device through the NAS message, which can have the following structure. The ProvideSenRSConfigurationB is used as the configuration information of the sensing reference signal of the fourth communication device in the NAS message.

[0293] The ProvideSenRSConfigurationB configuration in the NAS message can adopt the structure as shown in Figure 14 . For example, the ProvideSenRSConfigurationB configuration includes Figure 11The SenRSConfiguration configuration, the sensing mode configuration, and the device identification configuration, etc. shown in the middle (1).

[0294] The ProvideSenRSConfigurationB configuration can adopt the structure shown in the middle (3). For example, the ProvideSenRSConfigurationB configuration can contain two configurations with the same level: the SenRS-AssistanceData configuration and the Selected-SenRS-IndexList configuration. Figure 11

[0295] The SenRS-AssistanceData configuration and the Selected-SenRS-IndexList configuration can refer to the description of the SenRS-AssistanceData configuration and the Selected-SenRS-IndexList configuration in the ProvideSenRSConfigurationA configuration in the present application, and will not be described in detail.

[0296] Based on the structure shown in the middle (3), the pseudo code of an exemplary ProvideSenRSConfigurationB configuration is as follows: Figure 14

[0297] In addition, referring to the description of the middle (1) and (2), when the second communication device sends the receiving configuration information to the second communication device through the NAS message, the receiving configuration information can also be carried in the SenRSConfiguration configuration or the SenRS-Config configuration, which is not specifically limited.

[0298] Figure 11 In a possible embodiment, the receiving configuration information (such as ProvideSenRSConfigurationB) of the sensing reference signal sent by the second communication device to the fourth communication device and the receiving configuration information (such as ProvideSenRSConfigurationA) of the sensing reference signal sent by the second communication device to the terminal device correspond to different protocol layers in the NAS layer, respectively.

[0299] In a possible embodiment, the receiving configuration information (such as ProvideSenRSConfigurationB) of the sensing reference signal sent by the second communication device to the fourth communication device and the receiving configuration information (such as ProvideSenRSConfigurationA) of the sensing reference signal sent by the second communication device to the terminal device correspond to different protocol layers in the NAS layer, respectively.

[0300] ​​In another possible embodiment, the reception configuration information of the sensing reference signal sent by the second communication device to the fourth communication device (e.g., ProvideSenRSConfigurationB) and the reception configuration information of the sensing reference signal sent by the second communication device to the terminal device (e.g., ProvideSenRSConfigurationA) can be carried by one information element due to the similar functions and similar contents carried. The information element can contain a mode configuration to distinguish different configuration information. For example, if the mode configuration indicates that the sensing mode is base station sending and terminal device receiving, it means that the information element carries the reception configuration information of the sensing reference signal sent by the second communication device to the terminal device. For another example, if the mode configuration indicates that the sensing mode is base station sending and base station receiving, it means that the information element carries the reception configuration information of the sensing reference signal sent by the second communication device to the fourth communication device.

[0301] In a possible implementation, the information element for carrying the reception configuration information of the sensing reference signal sent by the second communication device to the fourth communication device and / or the reception configuration information of the sensing reference signal sent by the second communication device to the terminal device can be referred to as ProvideSenRSConfiguration configuration. As shown in Figure 15 , the ProvideSenRSConfiguration configuration can contain a SenRS-AssistanceData configuration, a Selected-SenRS-IndexList configuration and a mode configuration. The SenRS-AssistanceData configuration and the Selected-SenRS-IndexList configuration can be referred to the description in (2) of Figure 11 .

[0302] Based on the structure shown in Figure 15 , an exemplary pseudo code of the ProvideSenRSConfiguration configuration is as follows:

[0303]

[0304] In a possible implementation, the ProvideSenRSConfiguration configuration can be encapsulated in the LTE positioning protocol or the NR positioning protocol A.

[0305] If encapsulated in the LTE positioning protocol, the ProvideSenRSConfiguration configuration can be encapsulated in the ProvideAssistanceData configuration, as shown in (1) of Figure 16 . In addition, if encapsulated in the NR positioning protocol A, the ProvideSenRSConfiguration configuration can be encapsulated in the ProvideAssistanceData configuration, as shown in (2) of Figure 16As shown in FIG. 2, if encapsulated in the NR positioning protocol A, the ProvideSenRSConfiguration configuration can be encapsulated in different transmission units at the same level as the PRSConfigurationRequest and / or PRSConfigurationResponse.

[0306] The PRSConfigurationRequest can represent a PRS configuration request sent by the second communication device to the fourth communication device, and the PRSConfigurationResponse can represent a PRS configuration response sent by the fourth communication device to the second communication device.

[0307] In a possible embodiment, the application supports dynamically activating the first communication device to send the first sensing reference signal.

[0308] In a possible implementation, the second communication device sends activation indication information to the first communication device for activating the sending of the first sensing reference signal. The activation indication information can be referred to as fourth indication information. The fourth indication information can be carried in a NAS message sent by the second communication device to the first communication device.

[0309] The content of the fourth indication information will be introduced below in combination with the activation mode.

[0310] In the application, the activation mode of the sensing reference signal can include semi-periodic activation and aperiodic activation. In semi-periodic activation, the third sensing reference signal can be used to indicate an activation period and an activation time of the sensing reference signal, and optionally an activation duration. The terminal device can activate the sending of the sensing reference signal periodically according to the period. The activation duration can be used to indicate the duration of sending the sensing reference signal each time.

[0311] In aperiodic activation, the fourth indication information can be used to indicate the activation time of the sensing reference signal, and optionally the activation duration. The terminal device can activate the sending of the sensing reference signal according to the activation time. The activation duration can be used to indicate the duration of sending the sensing reference signal.

[0312] The content of the fourth indication information will be introduced below in combination with the activation mode. Figure 17 The way in which the first communication device determines the configuration information of the first sensing reference signal will be introduced below. In the application, the first communication device can determine the configuration information of the first sensing reference signal based on the request of the second communication device.

[0313] As Figure 17As shown, the second communication device can send first request information to the first communication device, the first request information being used to request configuration information of one or more first sensing reference signals. The first request information can be referred to as a base station sensing reference signal configuration request (BSSenRSConfigurationRequest). The first communication device can query, determine or generate the configuration information of the one or more first sensing reference signals after receiving the first request information, the configuration information including transmission configuration information and / or reception configuration information. In addition, the first communication device can also send first response information to the second communication device, the first response information including the configuration information of the one or more first sensing reference signals.

[0314] Specifically, the first request information can include one or more of resource requirement information of the one or more first sensing reference signals, sensing mode information, transmission device information, reception device information or sensing procedure identification. One or more of the resource requirement information, the sensing mode information, the transmission device information, the reception device information or the sensing procedure identification can be a requirement for each first sensing reference signal, and the first communication device can determine the configuration information of each first sensing reference signal according to the requirement.

[0315] The resource requirement information can include frequency requirement information and / or time requirement information. The frequency requirement information can be used to indicate a frequency range of the first sensing reference signal, for example, including information such as bandwidth or frequency start position. The time requirement information can be used to indicate a time range of the first sensing reference signal, for example, including information such as time start position, time duration or period. In addition, the resource requirement information can also include resource mapping configuration, such as resource duration symbol number, frequency interval or QCL information, etc.

[0316] In the case where the first request information is used to request configuration information of multiple sensing reference signals, the resource requirement information can also include one or more frequency layers and / or TRP information. For example, the frequency layer corresponds to the resource requirement information of one or more resources, i.e., the first request information can include resource requirement information of one or more frequency layers. For another example, the TRP information corresponds to the resource requirement information of one or more resources, i.e., the first request information can include resource requirement information of one or more TRP information.

[0317] The sensing mode information can be the same as the sensing mode information in the configuration information of the first sensing reference signal.

[0318] The transmission device information can be used to indicate a transmission device of the first sensing reference signal, for example, the transmission device information includes an identification of a transmission device of the first sensing reference signal. In this application, for the first sensing reference signal, the transmission device is the first communication device.

[0319] The information of the receiving device can be used to indicate the receiving device of the first sensing reference signal, for example, the information of the receiving device includes the identification of the receiving device of the first sensing reference signal. In this application, for the first sensing reference signal, the receiving device can be the first communication device, the third communication device or the fourth communication device.

[0320] The identification of the sensing procedure can be used to indicate the sensing procedure corresponding to the first sensing reference signal, which can be the same as the sensing mode information in the configuration information of the first sensing reference signal.

[0321] In a possible embodiment, on the basis that the first communication device receives the first request information sent by the second communication device and sends the first response information to the second communication device, the second communication device and / or the first communication device can send the configuration information of the sensing reference signal to the sending device and / or the receiving device of one or more first sensing reference signals.

[0322] As shown in FIG. 1, taking the first communication device as the sending device of one or more first sensing reference signals as an example, the sending of the configuration information of the sensing reference signal can be implemented through the procedure shown in FIG. 2. Figures 18A-18C Figures 18A-18C As shown in FIG. 1, taking the first communication device as the sending device of one or more first sensing reference signals as an example, the sending of the configuration information of the sensing reference signal can be implemented through the procedure shown in FIG. 2.

[0323] As shown in FIG. 1, taking the first communication device as the sending device of one or more first sensing reference signals as an example, the sending of the configuration information of the sensing reference signal can be implemented through the procedure shown in FIG. 2. Figure 18A As shown in FIG. 1, taking the first communication device as the sending device of one or more first sensing reference signals as an example, the sending of the configuration information of the sensing reference signal can be implemented through the procedure shown in FIG. 2.

[0324] It can be understood that Figure 18A The order of sending the RRC message carrying the first configuration information and the first response information by the first communication device is not limited.

[0325] As shown in FIG. 1, taking the first communication device as the sending device of one or more first sensing reference signals as an example, the sending of the configuration information of the sensing reference signal can be implemented through the procedure shown in FIG. 2. Figure 18B ​As shown, in a scenario where the first communication device acts as a transmitter of one or more first sensing reference signals, and the fourth communication device acts as a receiver of one or more first sensing reference signals, after the first communication device determines the configuration information of the first sensing reference signals based on the first request information from the second communication device, it can send a first response message to the second communication device. The first communication device can also send first configuration information to the fourth communication device via an inter-base station interface message. The first configuration information may carry reception configuration information for one or more first sensing reference signals. The first communication device can determine the transmission configuration information and / or reception configuration information for one or more first sensing reference signals based on the first request information.

[0326] Understandable. Figure 18B The order in which the first communication device sends the RRC message carrying the first configuration information, the RRC message carrying the second configuration information, and the first response information is not restricted.

[0327] like Figure 18C As shown, in a scenario where the first communication device acts as both a transmitter and receiver of one or more first sensing reference signals, i.e., a self-transmitting and self-receiving scenario, after the first communication device determines the configuration information of the first sensing reference signal based on the first request information of the second communication device, it can send a first response information to the second communication device. This configuration information can include transmission configuration information and reception configuration information.

[0328] Understandable, Figures 18A-18B The following explanation uses the example of the first communication device providing configuration information for the sensing reference signal to the third and fourth communication devices. For the implementation where the second communication device provides the configuration information for the sensing reference signal to the third and fourth communication devices via a NAS message, the second communication device, after receiving the first response information of the first request information, can provide the configuration information for the sensing reference signal to the first communication device or one of the fourth communication devices via a NAS message.

[0329] For example, it can be Figure 18A The first configuration information shown, sent from the first communication device to the third communication device, can be replaced with the first configuration information sent from the second communication device to the first communication device. For example, it can be... Figure 18B The first configuration information sent from the first communication device to the fourth communication device is replaced with the first configuration information sent from the second communication device to the first communication device.

[0330] The following is combined with Figure 19 This section describes the possible structure of the first request information.

[0331] likeFigure 19 As shown, the first request information can contain a requestedSenRSTransmissionCharacteristics configuration. Among them, BSSenRSConfigurationRequest represents the message (such as NAS message) or IE in which the first request information is located.

[0332] The requestedSenRSTransmissionCharacteristics configuration can contain one or more resource requirement information of the sensing reference signal.

[0333] In addition, the first request information can also contain a sensingMode configuration and a Device-ID configuration. Among them, the sensingMode configuration can be used to carry the sensing mode information in the first request information, and the Device-ID configuration can be used to carry the identification. In addition, the first request information can also contain a configuration for carrying the sensing procedure identifier, or the sensing procedure identifier is carried in the first request information.

[0334] The following pseudo code can be an example of the first request information containing the requestedSenRSTransmissionCharacteristics configuration, the sensingMode configuration and the Device-ID configuration:

[0335]

[0336] In a possible embodiment, the first response information corresponding to the first request information can be referred to as a base station sensing reference signal configuration response information (BSSenRSConfigurationResponse).

[0337] The first response information can contain one or more configuration information of the sensing reference signal. Among them, the one or more configuration information of the sensing reference signal includes the configuration information of the first sensing reference signal.

[0338] Specifically, the first response information can contain one or more of the resource configuration of the first sensing reference signal, the sensing mode information, the information of the sending device, the information of the receiving device, or the identifier of the sensing procedure.

[0339] The resource configuration of the first sensing reference signal can be understood as a specific time-frequency resource configuration of the sensing reference signal obtained on the basis of the requirement information of the resource of the sensing reference signal in the first request information. For example, the frequency configuration of the first sensing reference signal in the first response information can be determined according to the frequency range in the requirement information of the resource of the sensing reference signal in the first request information. For another example, the time configuration of the first sensing reference signal in the first response information can be determined according to the time range in the requirement information of the resource of the sensing reference signal in the first request information. In addition, the resource configuration of the first sensing reference signal can also include resource mapping configuration such as resource duration symbol number, frequency interval or QCL information. The resource mapping configuration can be the same as the resource mapping configuration in the requirement information of the resource, or can be different, and is not specifically limited.

[0340] The sensing mode information, the information of the sending device, the information of the receiving device and the identification of the sensing procedure can be the same as the sensing mode information, the information of the sending device, the information of the receiving device and the identification of the sensing procedure in the first request information, respectively. Therefore, it can be understood that the first communication device can provide or feed back the resource configuration of the corresponding sensing reference signal to the second communication device according to one or more of the requirement information of the resource of the sensing reference signal, the sensing mode information, the information of the sending device, the information of the receiving device and the identification of the sensing procedure in the first request information.

[0341] The following will be described in combination with Figure 20 The possible structure of the first response information is introduced.

[0342] As Figure 20 indicated, the first response information can include SenRSConfiguration configuration. BSSenRSConfigurationResponse represents a message (such as a NAS message) or an IE in which the first response information is located.

[0343] The SenRSConfiguration configuration can include resource configuration of one or more sensing reference signals. Specifically, the SenRSConfiguration configuration can include one or more sub-units or sub-configurations such as SenRSConfigurationPerFreq, SenRSConfigurationPerTRP, or SenRSConfiguration-Item. Among them, SenRSConfigurationPerFreq can be used to indicate the frequency layer to which the first sensing reference signal is applicable, which can be included in the frequency layer indicated in the first request information; SenRSConfigurationPerTRP can be used to indicate the TRP information to which the first sensing reference signal is applicable, which can be included in the TRP information indicated in the first request information; and SenRSConfiguration-Item is used to carry resource configuration to which the first sensing reference signal is applicable.

[0344] In addition, the first response information can also include a sensingMode configuration and a Device-ID configuration. Among them, the sensingMode configuration can be used to carry sensing mode information, and the Device-ID configuration can be used to carry an identification. In addition, the first response information can also include a configuration for carrying sensing procedure identification, or the first response information carries the sensing procedure identification.

[0345] The following is an exemplary pseudo code of the first response information:

[0346]

[0347] In a possible embodiment, the first request information can be used to request configuration information of multiple sensing reference signals, wherein the multiple sensing reference signals can include the first sensing reference signal. Correspondingly, the first response information can include configuration information of the multiple sensing reference signals.

[0348] Specifically, the multiple sensing reference signals can correspond to a transmitting device of the multiple sensing reference signals, and / or a receiving device of the multiple sensing reference signals. The multiple sensing reference signals can include the first sensing reference signal, a second sensing reference signal, or other sensing reference signals.

[0349] For example, for the first sensing reference signal, the transmitting device can be the first communication device, and the receiving device can be the first communication device, the first communication device, the third communication device, or other communication devices. The other communication devices can be, for example, other terminal devices other than the first communication device or the third communication device, or other base stations or access network devices other than the first communication device.

[0350] For example, the transmitting device of the second sensing reference signal can be the third communication apparatus.

[0351] In the case that the first request information is used for requesting configuration information of multiple sensing reference signals, the first request information can comprise one or more of requirement information of resources of the multiple sensing reference signals, sensing mode information, information of the transmitting device, information of the receiving device, or identification of a sensing procedure. Correspondingly, the first response information can comprise configuration information of the multiple sensing reference signals.

[0352] The following describes a manner that the first request information requests configuration information of multiple sensing reference signals, and the first response information feeds back configuration information of the multiple sensing reference signals.

[0353] In manner D1, different configuration request information (e.g., including the first request information and other request messages) and response information (e.g., including the first response information and other response messages) of different sensing reference signals have different identification of sensing procedures. The identification of sensing procedures can be denoted as transactionID, as shown in the following pseudo code:

[0354]

[0355] It can be understood that if the first communication apparatus determines the configuration information of the multiple sensing reference signals according to the first request information, the first communication apparatus or the second communication apparatus can respectively send the configuration information of the multiple sensing reference signals to the transmitting devices and / or receiving devices of the multiple sensing reference signals. For example, as shown in the following pseudo code, taking the multiple sensing reference signals as being sent by the first communication apparatus and received by the multiple terminal devices as an example, if the receiving device of the sensing reference signal #1 is the terminal device #1, and the receiving device of the sensing reference signal #2 is the terminal device #2, the second communication apparatus can send the receiving configuration information of the sensing reference signal #1 to the terminal device #1, and send the receiving configuration information of the sensing reference signal #2 to the terminal device #2. Figure 21 Figure 21 In the pseudo code, the first request information #1 and the first response information #1 can correspond to the sensing procedure identification #1, and the first request information #2 and the first response information #2 can correspond to the sensing procedure identification #2, i.e., the configuration information of different sensing reference signals corresponds to different sensing request / response messages.

[0356] In addition, the first communication apparatus can also send the receiving configuration information of the sensing reference signal #1 to the terminal device #1, and send the receiving configuration information of the sensing reference signal #2 to the terminal device #2.

[0357] ​In the manner D2, one or more of the parameters such as the resource requirement information and the sensing mode information, the information of the transmitting device, or the information of the receiving device can be indicated in the first request information for different sensing procedures. Similarly, if the first response information contains the configuration information of multiple sensing reference signals, one or more of the parameters such as the resource configuration and the sensing mode information, the information of the transmitting device, or the information of the receiving device can be indicated in the first response information for different sensing procedures.

[0358] For example, different Transaction IDs and corresponding parameters can be carried in the BSSenRSConfigurationRequest and the BSSenRSConfigurationResponse.

[0359] For example, the transactionIDSet, the txDeviceIdSet, the rxDeviceIdSet, and the requestedUESenRSTransmissionCharacteristicsSet in the BSSenRSConfigurationRequest and the BSSenRSConfigurationResponse can carry the parameters corresponding to different Transaction IDs, as shown in the following pseudo code:

[0360]

[0361] It can be understood that if the first communication device determines the configuration information of multiple sensing reference signals according to the first request information, the first communication device or the second communication device can send the configuration information of the multiple sensing reference signals to the receiving devices of the multiple sensing reference signals, respectively. As shown in the following figure, taking the example that the multiple sensing reference signals are sent by the first communication device and received by multiple access network devices, if the receiving device of the sensing reference signal #1 is the access network device #1, and the receiving device of the sensing reference signal #2 is the access network device #2, the configuration information of the multiple sensing reference signals can be requested through the same sensing request information (such as the first request information in the figure), and the configuration information of the multiple sensing reference signals can be fed back through the same response information (such as the first response information in the figure). As shown in the figure, the receiving configuration information of the sensing reference signal #1 can be sent by the second communication device to the access network device #1, and the receiving configuration information of the sensing reference signal #2 can be sent by the second communication device to the access network device #2. Figure 22

[0362] In addition, the receiving configuration information of the sensing reference signal #1 can also be sent by the first communication device to the access network device #1, and the receiving configuration information of the sensing reference signal #2 can also be sent by the first communication device to the access network device #2.

[0363] ​In a possible implementation, the manner D1 can be applicable to a scenario where all the receiving devices of the multiple sensing reference signals are terminal devices. The manner D2 can be applicable to a scenario where all the receiving devices of the multiple sensing reference signals are access network devices.

[0364] In actual communication, the sensing task (or sensing function) can be related to the positioning task (or positioning function). For example, the positioning task (or positioning function) can belong to part of the sensing task (or sensing function), or the positioning task (or positioning function) is relatively independent of the sensing task (or sensing function), but the two can assist each other. In order to facilitate the transmission of the configuration information of the first sensing reference signal and the information related to the positioning task (hereinafter referred to as positioning information), in a possible implementation, the first transmission unit is related to (or associated with) a transmission unit for carrying the positioning information.

[0365] In a possible implementation, the first request information can be carried in the same NAS message as the positioning information request. The positioning information request can be used to request positioning service related configuration information, for example, including positioning related reference signal configuration. As explained in this application, the positioning related reference signal is, for example, PRS, SRS or CSI-RS, etc. The positioning related reference signal configuration can be specifically request information or response information for requesting the configuration of the above-mentioned positioning related reference signal. Taking PRS as an example, the positioning information request can be used to request PRS configuration, such as PRS configuration request (PRSConfigurationRequest), see the definition in NR positioning protocol A.

[0366] The first request information and the positioning information request can satisfy the following positional relationship:

[0367] Position relationship E1, embedded: in the NAS message, the first request information is embedded in the positioning information request, or the first request information is contained in the positioning information request. For example, the first request information can be a sub-transmission unit of the transmission unit for carrying the positioning information request. Among them, the transmission unit for carrying the first request information can be the fourth transmission unit, the transmission unit for carrying the positioning information request can be referred to as the sixth transmission unit, and the fourth transmission unit can be a sub-transmission unit of the sixth transmission unit. For example, Figure 23As shown in the middle number (1), BSSenRSConfigurationRequest represents the first request information, and PRSConfigurationRequest represents the positioning information request. The position relationship E1 can also be described as: BSSenRSConfigurationRequest is a sub-transmission unit of PRSConfigurationRequest.

[0368] Based on the position relationship E1, an exemplary NAS message can be implemented by the following pseudo code:

[0369]

[0370] The position relationship E2 is parallel: in the NAS message, the first request information and the positioning information request are located in two transmission units in parallel, as shown in the middle number (2). Among them, the transmission unit for carrying BSSenRSConfigurationRequest can be referred to as a fourth transmission unit, and the transmission unit for carrying PRSConfigurationRequest can be referred to as a fifth transmission unit. The fourth transmission unit and the fifth transmission unit are two transmission units in parallel. The position relationship E2 can also be described as: PRSConfigurationRequest and BSSenRSConfigurationRequest are transmission units with the same level, which do not contain each other between the same transmission units, and are located in the same configuration. Figure 23

[0371] Based on the position relationship E2, an exemplary NAS message can be implemented by the following pseudo code:

[0372]

[0373] The position relationship E3 is combined: in the NAS message, the first request information and the positioning information request can be carried in the same transmission unit, which is a transmission unit combined by the first request information and the positioning information request, for example, ISACRSConfigurationRequest shown in the middle number (3). For example, the transmission unit for carrying BSSenRSConfigurationRequest can be referred to as a fourth transmission unit, and the transmission unit for carrying PRSConfigurationRequest can be referred to as a fifth transmission unit. The fourth transmission unit and the fifth transmission unit are two sub-transmission units in ISACRSConfigurationRequest. It can also be said that the first request information and the positioning information request can be combined as a transmission unit, such as Figure 23 Figure 23 ​​The first response information can be carried in the same NAS message as the positioning information response, as shown in number (3).

[0374] Based on the location relationship E3, an exemplary NAS message can be implemented by the following pseudo code:

[0375]

[0376] Similarly, the first response information can be carried in the same NAS message as the positioning information response. The positioning information response can carry the configuration information related to the positioning service, such as carrying the positioning reference signal configuration. Taking PRS as an example, the positioning information response can be used for the first communication device to feed back the PRS configuration to the second communication device, which is called PRS configuration response (PRSConfigurationResponse), as defined in NRPPa.

[0377] As shown in number (1) in Figure 23 , BSSenRSConfigurationResponse represents the first response information, and PRSConfigurationResponse represents the positioning information response. As shown in number (2) in Figure 23 , the first response information can be embedded in the positioning information response, or in other words, the seventh transmission unit used to carry the first response information can be a sub-transmission unit of the ninth transmission unit, and the ninth transmission unit can also be used to carry the positioning information response. As shown in number (3) in Figure 23 , the seventh transmission unit used to carry the first response information and the eighth transmission unit used to carry the positioning information response can be carried in two transmission units in parallel. As shown in number (4) in Figure 24 , the first response information and the positioning information response can be carried in the same transmission unit.
