Description

A communication method and related apparatus

[0001] The present application claims priority to the Chinese patent application No. CN202411514210.2, filed on October 28, 2024, and entitled "A communication method and related apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication, in particular to a communication method and related apparatus. BACKGROUND

[0003] In the process of communication technology evolution, integrated sensing and communication (ISAC) technology is considered as one of the key technologies to expand the business capabilities of mobile communication networks. The integrated sensing and communication technology can also be referred to as sensing technology. The core idea of the technology is to add sensing capabilities on the mobile communication network to build the ability to detect, track and image the target, so that the communication and sensing capabilities are integrated in one network.

[0004] In the sensing technology, the sensing mode can generally be divided into two types: monostatic and bistatic. Among them, monostatic is also called single station sensing. Monostatic refers to the sending end and receiving end of the measurement signal being the same device. From the measurement signal flow, the sensing station not only transmits the measurement signal, but also receives the signal reflected on the surface of the obstacle (also known as echo signal). Therefore, the monostatic mode is also called self-transmitting and self-receiving mode. For bistatic, the sending end and receiving end of the measurement signal are different devices. From the measurement signal flow, sensing station A transmits the measurement signal, and the signal reflected on the surface of the obstacle is received by sensing station B. Therefore, the bistatic mode is also called A-transmitting and B-receiving mode.

[0005] From the above introduction of the sensing mode, it can be known that the sending end and receiving end of the measurement signal are different under different sensing modes. For different sensing modes, the measurement signal needs to be configured respectively, which increases the communication overhead of sensing measurement. SUMMARY

[0006] Embodiments of the present application propose a communication method and related apparatus. Through the configuration information, the measurement signal suitable for different sensing modes can be flexibly configured, and the measurement signal under different sensing modes can be uniformly scheduled to improve the accuracy of sensing measurement.

[0007] In a first aspect, embodiments of the present application propose a communication method. The method is applied to a first device.

[0008] In one possible implementation, the first device may be a terminal device, or a component in the terminal device (e.g., a processor, device, chip, circuit, chip or chip system, etc.), or a logic module or software that can implement all or part of the functions of the terminal device. This application does not limit the specific implementation.

[0009] In another possible implementation, the first device may be a network device, or a component of the network device (e.g., a processor, device, chip, circuit, chip or chip system, etc.), or a logic module or software that can implement all or part of the functions of the terminal device, or at least one of a centralized unit (CU) or a distributed unit (DU), the specific of which is not limited in this application.

[0010] The method includes: a first device acquiring configuration information, the configuration information indicating a sensing mode and the resources of the measurement signal corresponding to the sensing mode; then, the first device outputting a measurement signal, the measurement signal being carried on the resources of the measurement signal corresponding to the sensing mode.

[0011] The first device determines the resources of the measurement signal and the sensing mode corresponding to the measurement signal based on the configuration information. Then, the first device performs the sensing measurement corresponding to the sensing mode according to the configuration information. Specifically, the first device outputs the measurement signal based on the resources of the measurement signal. Exemplarily, the measurement signal in this embodiment can be a cooperative sensing reference signal (CS-RS). It should be noted that the measurement signal in this embodiment can also be other types of reference signals, and this embodiment does not limit this.

[0012] Optionally, the configuration information indicating the sensing mode and the resources of the measurement signal corresponding to the sensing mode can be replaced with: the configuration information indicating the resources of the measurement signal and the sensing mode applicable to the measurement signal; or, the configuration information indicating the resources of the measurement signal and the sensing mode corresponding to the measurement signal.

[0013] In the above technical solution, measurement signals applicable to different sensing modes can be flexibly configured through configuration information. If the first device performs sensing measurements in multiple different sensing modes, the first device can uniformly schedule the various measurement signals involved in these different sensing modes to improve the accuracy of sensing measurements and reduce the communication overhead of sensing measurements.

[0014] In conjunction with the first aspect, in one possible implementation of the first aspect, the output measurement signal includes:

[0015] If a first activation command is output, a measurement signal is output; or, if a second activation command is output, the measurement signal is output K times repeatedly, where K is an integer greater than or equal to 1. The first activation command instructs the first device to output a measurement signal, which the third device needs to receive. The second activation command instructs the first device to output the measurement signal K times repeatedly, which the third device needs to receive.

[0016] In one example scenario, the first device starts timing after outputting a first activation command. When the timing reaches a first preset time, the first device starts outputting a measurement signal.

[0017] In another example scenario, the first device starts timing after outputting a second activation command. When the timing reaches a first preset time, the first device begins outputting a measurement signal. During the process of repeatedly outputting the measurement signal K times, the time interval between two adjacent measurement signals is a second preset time. For example, the second preset time is 3 milliseconds.

[0018] For example, the first activation instruction may be a bit of length 1, and the third device determines the first activation instruction based on this bit. Similarly, the second activation instruction may also be a bit of length 1, and the third device determines the second activation instruction based on this bit.

[0019] For example, the first activation instruction or the second activation instruction may be carried in any of the following messages, information or signaling: media access control control element (MAC CE), downlink control information (DCI), or sidelink control information (SCI).

[0020] The above methods can flexibly output measurement signals, improve the compatibility between measurement signals and sensing modes, enhance sensing measurement accuracy, and save communication overhead in sensing measurement.

[0021] In conjunction with the first aspect, in one possible implementation of the first aspect, the method further includes: if an output deactivation instruction is output, then the output measurement signal is stopped.

[0022] The above methods can flexibly output measurement signals, improve the compatibility between measurement signals and sensing modes, enhance sensing measurement accuracy, and save communication overhead in sensing measurement.

[0023] Secondly, embodiments of this application propose a communication method, which is applied to a second device.

This application does not limit the specific implementation.

[0025] In another possible implementation, the second device may be a network device, or a component of the network device (e.g., a processor, device, chip, circuit, chip or chip system, etc.), or a logic module or software that can implement all or part of the functions of the terminal device, or at least one of a centralized unit (CU) or a distributed unit (DU), which is not limited in this application.

[0026] The method includes: first, a second device determining a sensing mode; second, the second device outputting configuration information indicating the sensing mode and the resources of the measurement signal corresponding to the sensing mode.

[0027] In the above technical solution, the second device can flexibly configure measurement signals applicable to different sensing modes through configuration information, and realize unified scheduling of measurement signals under different sensing modes, so as to improve the accuracy of sensing measurement and reduce the communication overhead of sensing measurement.

[0028] Thirdly, embodiments of this application propose a communication method applied to a third device.

[0029] In one possible implementation, the third device may be a terminal device, a component of the terminal device (e.g., a processor, device, chip, circuit, chip or chip system, etc.), or a logic module or software that can implement all or part of the functions of the terminal device.

For example, if the value of the first information is 0, it indicates that the sensing mode corresponding to the measurement signal is sensing mode 0. Through the first information, the sensing mode of the measurement signal can be flexibly indicated to adapt to sensing measurements in different scenarios.

[0037] In conjunction with the first aspect, the second aspect, and / or the third aspect, in one possible implementation of the first aspect, the second aspect, and / or the third aspect, the configuration information includes: second information, which is used to configure resources for the measurement signal.

[0038] In a possible implementation of the first, second, and / or third aspects, the configuration information includes M pieces of third information, each piece of third information configuring resources for N measurement signals, where M is an integer greater than or equal to 1 and N is an integer greater than or equal to 1. For example, each piece of third information includes N pieces of second information. This measurement signal resource set information can also be referred to as "CSRS-ResourceSet" information.

[0039] In conjunction with the first aspect, the second aspect, and / or the third aspect, in one possible implementation of the first aspect, the second aspect, and / or the third aspect, the configuration information includes: fourth information, the fourth information indicating the output mode of the measurement signal, the output mode of the measurement signal including any one of the following: periodic output of the measurement signal, semi-static output of the measurement signal, non-periodic output of the measurement signal, or, fixed-number repeated output of the measurement signal, wherein the semi-static output of the measurement signal is: the measurement signal is repeatedly output after the first activation instruction is output, and the output of the measurement signal stops after the deactivation instruction is output; the non-periodic output of the measurement signal is: the measurement signal is output once or multiple times after the second activation instruction is output; the fixed-number repeated output of the measurement signal is: the measurement signal is repeatedly output K times, where K is an integer greater than or equal to 1.

[0040] By using the fourth information, the output mode of the measurement signal can be flexibly configured to adapt to the sensing measurement in different scenarios, improve the accuracy of sensing measurement, and save the overhead of sensing signals.

[0041] In conjunction with the first aspect, the second aspect, and / or the third aspect, in one possible implementation of the first aspect, the second aspect, and / or the third aspect, if the configuration information indicates that the output mode of the measurement signal is: the measurement signal is repeatedly output a fixed number of times, the configuration information further includes: a fixed number of repetition parameters, the fixed number of repetition parameters indicating that the measurement signal is repeatedly output K times.

[0042] In conjunction with the first aspect, the second aspect, and / or the third aspect, in one possible implementation of the first aspect, the second aspect, and / or the third aspect, if the configuration information indicates that the output method of the measurement signal is to periodically output the measurement signal, the configuration information includes: periodicity and offset, wherein the periodicity and offset indicate the output period of the measurement signal, and / or, the output time slot offset of the measurement signal; the output method of the measurement signal includes semi-static output of the measurement signal, the configuration information including: periodicity and offset; the output method of the measurement signal includes non-periodic output of the measurement signal, the configuration information including: non-periodic trigger offset, the non-periodic trigger offset indicating the time slot interval offset between the second activation command and the measurement signal; the output method of the measurement signal includes outputting the measurement signal a fixed number of times, the configuration information including: periodicity and offset, and / or, a fixed number of repetition parameters (fixedRepeatNumber).

[0043] In conjunction with the first aspect, the second aspect, and / or the third aspect, in one possible implementation of the first aspect, the second aspect, and / or the third aspect, the configuration information further includes: fifth information, which indicates the physical channel carrying the measurement signal, the physical channel including any one of the following: physical channel 0: physical broadcast channel (PBCH), physical channel 1: physical downlink shared channel (PDSCH), physical channel 2: physical downlink control channel (PDCCH), physical channel 3: physical uplink shared channel (PUSCH), physical channel 4: physical uplink control channel (PUCCH), physical channel 5: physical sidelink share channel (PSSCH), physical channel 6: physical sidelink control channel (PSCCH), physical channel 7: physical sidelink broadcast channel (PSBCH), physical channel 8: physical sidelink feedback channel. Physical Channel 10: Downlink, Physical Channel 11: Sidelink, Physical Channel 12: Crosslink, and Physical Channel 13: Backhaul link.

[0044] Specifically, an uplink refers to the link from a terminal device to a network device. A downlink refers to the link from a network device to a terminal device. A sidelink refers to the link between terminal devices. A crosslink refers to an interference link between network devices. A backlink refers to a link between network devices.

[0045] By leveraging the fifth piece of information, the physical channels carrying measurement signals can be flexibly configured to adapt to different sensing and measurement scenarios, thereby improving the accuracy of sensing and measurement and saving on the overhead of sensing signals.

[0046] Furthermore, the constraint relationship between the sensing mode of the measurement signal and the physical channel carrying the measurement signal is as follows:

[0047] If the first information indicates that the sensing mode corresponding to the measurement signal is sensing mode 0, the fifth information indicates the physical channel carrying the measurement signal, including any one of the following: physical channel 0, or physical channel 9;

[0048] If the first information indicates that the sensing mode corresponding to the measurement signal is sensing mode 1, the fifth information indicates the physical channel carrying the measurement signal, including any one of the following: physical channel 9, physical channel 12, or physical channel 13;

[0049] If the first information indicates that the sensing mode corresponding to the measurement signal is sensing mode 2, the fifth information indicates the physical channel carrying the measurement signal, including any one of the following: physical channel 1, physical channel 2, or physical channel 9;

[0050] If the first information indicates that the sensing mode corresponding to the measurement signal is sensing mode 3, the fifth information indicates the physical channel carrying the measurement signal, including any one of the following: physical channel 3, physical channel 4, or physical channel 10;

[0051] If the first information indicates that the sensing mode corresponding to the measurement signal is sensing mode 4, the fifth information indicates the physical channel carrying the measurement signal, including any one of the following: physical channel 7, or physical channel 11;

[0052] If the first information indicates that the sensing mode corresponding to the measurement signal is sensing mode 5, the fifth information indicates the physical channel carrying the measurement signal, including any one of the following: physical channel 5, physical channel 6, physical channel 8, or physical channel 11.

[0053] In conjunction with the first aspect, the second aspect, and / or the third aspect, in one possible implementation of the first aspect, the second aspect, and / or the third aspect, the configuration information further includes: sixth information, the sixth information indicating the resources carrying the measurement signal, the resources carrying the measurement signal including one or more of the following: a first communication resource, or a second communication resource, wherein the first communication resource is carried on any of the following physical channels: physical broadcast channel PBCH, physical downlink shared channel PDSCH, physical downlink control channel PDCCH, physical uplink shared channel PUSCH, physical uplink control channel PUCCH, physical side link shared channel PSSCH, physical side link control channel PSCCH, physical side link broadcast channel PSBCH, physical side link feedback channel PSFCH, and the second communication resource is carried on any of the following physical channels: uplink, downlink, side link, cross link, or backhaul link.

[0054] In the above technical solution, the first communication resource can also be called the pilot communication resource, and the second communication resource can also be called the payload communication resource. The sixth information enables flexible indication of the resources carrying the measurement signal, thereby improving the flexibility of the solution.

[0055] In conjunction with the first aspect, the second aspect, and / or the third aspect, in one possible implementation of the first aspect, the second aspect, and / or the third aspect, the configuration information further includes: seventh information, which indicates the type of pilot signal for multiplexing the measurement signal. The type of pilot signal includes any one or more of the following: communication pilot signal, positioning pilot signal, or sensing pilot signal, wherein the measurement result of the communication pilot signal is used for communication, the measurement result of the positioning pilot signal is used for positioning, and the measurement result of the sensing pilot signal is used for sensing.

[0056] For example, communication pilot signals are used for channel estimation so that communication can be carried out based on the results of the channel estimation.

[0057] For example, the communication pilot signal includes: a channel state information-reference signal (CSI-RS), a sounding reference signal (SRS), and / or a phase tracking reference signal (PTRS). The positioning pilot signal includes: a positioning reference signal (PRS), and / or a positioning-specific SRS.

[0058] In a further example, the communication pilot signal includes a first type of communication pilot signal and a second type of communication pilot signal. A first device outputs a first type of communication pilot signal, which is used for channel estimation. The first device also outputs a second type of communication pilot signal, which serves as the measurement signal in this embodiment. A third device performs different operations based on the type of the communication pilot signal. The third device performs channel measurement on the first type of communication pilot signal to obtain a channel estimation result. The third device performs sensing measurement on the second type of communication pilot signal to obtain a sensing measurement result for the second type of communication pilot signal. For example, the first type of communication pilot signal is a type 1 CSI-RS, and the second type of communication pilot signal is a type 2 CSI-RS.

[0059] If the seventh information indicates that the pilot type of the measurement signal is a communication pilot signal, the measurement signal can reuse the communication pilot signal. That is, the first device can use the communication pilot signal as the measurement signal, and the first device does not need to actually output the measurement signal, but performs sensing measurement through the communication pilot signal. In this case, the configuration information can include only the seventh information.

[0060] In the above technical solution, the pilot signal is reused for the measurement signal through the seventh information, so as to save the communication overhead of the measurement signal and improve the implementation flexibility of the solution.

[0061] In conjunction with the first aspect, the second aspect, and / or the third aspect, in one possible implementation of the first aspect, the second aspect, and / or the third aspect, if the configuration information includes sixth information, and the sixth information indicates that the resource for measuring the signal includes the first communication resource, the configuration information also includes seventh information.

[0063] The above technical solutions can save processing costs for network equipment and / or terminal devices and improve privacy and security.

[0064] In conjunction with the first aspect, the second aspect, and / or the third aspect, in one possible implementation of the first aspect, the second aspect, and / or the third aspect, if the first information indicates that the sensing mode corresponding to the measurement signal is sensing mode 0, sensing mode 1, or sensing mode 2, the eighth information indicates that the network device does not transmit the configuration information; if the first information indicates that the sensing mode corresponding to the measurement signal is sensing mode 0, sensing mode 1, or sensing mode 2, the ninth information indicates that the terminal device transmits or does not transmit the configuration information; if the first information indicates that the sensing mode corresponding to the measurement signal is sensing mode 3, sensing mode 4, or sensing mode 5, the eighth information indicates that the network device transmits or does not transmit the configuration information; if the first information indicates that the sensing mode corresponding to the measurement signal is sensing mode 3, sensing mode 4, or sensing mode 5, the ninth information indicates that the terminal device does not transmit the configuration information.

[0065] In conjunction with the first aspect, the second aspect, and / or the third aspect, in one possible implementation of the first aspect, the second aspect, and / or the third aspect, the configuration information further includes: tenth information, wherein the tenth information indicates one or more of the following: the resource element (RE) occupied by the measurement signal in the physical resource block (PRB) in the frequency domain; the starting position of the measurement signal in the orthogonal frequency division multiplexing (OFDM) symbol in the time domain; the number of antenna ports carrying the measurement signal; the code division multiplexing (CDM) pattern information of the measurement signal; the frequency domain density information of the measurement signal; or, the frequency band information of the measurement signal, the frequency band information of the measurement signal indicating the starting resource block (RB) position of the measurement signal in the frequency domain and the number of RBs occupied by the measurement signal in the frequency domain.

[0066] Specifically, the CDM pattern information of the measurement signal indicates the transmission rules when the first device transmits the measurement signal using the CDM method. When the first device transmits the measurement signal using the CDM method, the measurement signals carried by different antenna ports use the same set of REs. Therefore, the first device distinguishes the measurement signals carried by different antenna ports through a set of orthogonal codewords. For example, the CDM pattern information of the measurement signal includes any of the following: "noCDM", "fd-CDM2", "CDM4-FD2-TD2", or "CDM8-FD2-TD4", where noCDM means the measurement signal is mapped to only one resource element (RE); fd-CDM2 means the measurement signal is multiplexed on two REs and two carriers in the frequency domain and one symbol in the time domain; CDM4-FD2-TD2 means the measurement signal is multiplexed on four REs and two carriers in the frequency domain and two symbols in the time domain; and CDM8-FD2-TD4 means the measurement signal is multiplexed on eight REs and two carriers in the frequency domain and four symbols in the time domain. with two carriers in the frequency domain and four symbols in the time).

[0067] For example, the frequency domain density information of the measurement signal includes RE pattern information of the measurement signal, which indicates the number of REs occupied by the measurement signal within one PRB in the frequency domain.

[0118] References to "one embodiment" or "some embodiments" as described in this application mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0119] In the description of this application, unless otherwise stated, " / " means "or". For example, A / B can mean A or B. "And / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" means one or more, and "multiple" means two or more. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or multiple items. For example, at least one of a, b, or c can represent: a, b, c, a and b, a and c, b and c, or a and b and c. Where a, b, and c can be single or multiple.

[0120] First, the communication system involved in the embodiments of this application is introduced. This application can be applied to long-term evolution (LTE) systems, new radio (NR) systems, or future communication systems after 5G. The communication system includes at least one network device and / or at least one terminal device.

[0121] Figure 1 is a schematic diagram of the architecture of the communication system 1000 used in the embodiments of this application.

[0122] As shown in Figure 1, the communication system includes a wireless access network 100 and a core network 200. Optionally, the communication system 1000 may also include an Internet 300. The wireless access network 100 may include at least one network-side device (the network-side device in this embodiment can also be understood as a network device, such as 110a and 110b in Figure 1, which can also be called an access network device), and at least one terminal (which can also be understood as the terminal device described above, such as 120a-120j in Figure 1). Furthermore, the network device (or wireless network device) can be a macro base station (as shown in Figure 1, 110a), a micro base station or an indoor station (as shown in Figure 1, 110b), a relay node or a donor node, etc. It is understood that all or part of the functions of the network device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (e.g., a cloud platform). The embodiments of this application do not limit the specific technology or specific device form adopted by the wireless network device.

[0123] For ease of description, the communication system illustrated in Figure 1 is described using the network device as a base station and the terminal device as a terminal. It is understood that if the communication system includes an integrated access and backhaul (IAB) network, the base station can be an IAB node. It should be noted that in the embodiments of this application, the base station and the network device can be interchanged.

[0124] In this application, the base station and the terminal can be fixed or mobile. The base station and the terminal can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted, on water, or in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of the base station and the terminal.

[0125] The roles of base station and terminal can be relative. For example, the helicopter or drone 120i in Figure 1 can be configured as a mobile base station. For terminals 120j that access the wireless access network 100 through 120i, terminal 120i is a base station. However, for base station 110a, 120i is a terminal, meaning that 110a and 120i communicate via a wireless air interface protocol. Alternatively, 110a and 120i can also communicate via a base station-to-base station interface protocol; in this case, 120i is also a base station relative to 110a. Therefore, both base station and terminal can be collectively referred to as communication devices. 110a and 110b in Figure 1 can be called communication devices with base station functions, and 120a-120j in Figure 1 can be called communication devices with terminal functions.

[0126] Communication between base stations and terminals, between base stations, and between terminals can be conducted using licensed spectrum, unlicensed spectrum, or both simultaneously. Communication can be achieved using spectrum below 6 GHz, spectrum above 6 GHz, or both simultaneously. The embodiments of this application do not limit the spectrum resources used for wireless communication.

[0127] Figure 2a is a schematic diagram of a communication system in an embodiment of this application. Referring to Figure 2a, the communication system includes user equipment (UE), radio access network (RAN) equipment (or simply network equipment), access and mobility management function (AMF), user plane function (UPF), unified data management (UDM), network data analytics function (NWDAF), location management function (LMF), policy control function (PCF), or network function (NEF).

[0128] The communication system also includes a sensing function (SF), which can establish connections with other core network functions, such as UPF, AMF, UDM, NWDAF, LMF, PCF, or NEF. The sensing function is responsible for configuring how sensing devices perform sensing measurements or interact with sensing requirements. It can also process sensing data. The sensing device can be either a RAN or a UE, and the sensing data can be, for example, data or information related to sensing measurements.

[0129] In one example, the LMF is used to calculate the location of the terminal device. The SF can store an environmental map, enabling environmental map reconstruction, and it interacts with the LMF to exchange environmental, measurement, and other information.

[0130] The name of the sensing function may change as the communication system evolves. Any functional network element with a name similar to SF can be understood as the SF of this application and is applicable to the methods provided in this application. For example, SF can also be a communication sensing function, sensing management function entity, sensing function network element, sensing network element, sensing server, or other names. This application does not limit the name of SF. The following embodiments mainly use the description of SF to introduce the execution operation of this functional network element. The interaction between SF and RAN or UE can be transmitted through AMF or directly. For example, sensing data acquired by RAN or UE can be transmitted to SF via control plane or user plane. Specifically, user plane can be forwarded from RAN or UE to SF via UPF, or RAN or UE can transmit directly to SF.

[0131] Figure 2b is another schematic diagram of the communication system in an embodiment of this application. Referring to Figure 2b, a sensing unit (SU) is added to the network device side of the communication system. This SU can be used to perform sensing-related functions, including but not limited to: the SU interacting with the SF to sense requirements, and the SU interacting with the core network equipment, RAN, or UE to sense data. The core network equipment is, for example, an AMF or UPF. For example, the RAN includes a centralized unit (CU) or a distributed unit (DU).

[0132] In one example, the UE outputs a measurement signal to the RAN. The measurement signal can be passed from the UE to the DU, then from the DU to the CU, and finally from the CU to the SU on the RAN side; or the measurement signal can be passed from the UE to the DU and then directly from the DU to the SU; or the UE can directly pass the measurement signal to the SU.

[0133] In another example, the RAN outputs configuration information to the UE. The configuration information can be passed from the SU on the RAN side to the CU, then from the CU to the DU, and finally from the DU to the UE; or the configuration information can be passed from the SU to the DU and then directly from the DU to the UE; or the SU can directly pass the configuration information to the UE.

[0134] The name of the sensing unit may change as the communication system evolves. Any functional network element with a name similar to SU can be understood as SU in this application and is applicable to the method provided in this application. For example, SU can also be a sensing computing unit, sensing computing module, sensing module, sensing computing board, computing device, or other names. This application does not limit the name of SU.

[0135] The sensing unit can be independent of the network device; for example, it can be deployed in an edge computing device, or it can be an external service board of the network device. Alternatively, the sensing unit can be co-located with the network device, for example, it can be a functional unit or module within the network device.

[0136] The technical solution of this application can be applied to cellular communication systems related to the 3rd Generation Partnership Project (3GPP). For example, 4th generation (4G) communication systems, 5G communication systems, and communication systems beyond the 5th generation. For example, future communication systems. For example, 4th generation communication systems may include Long Term Evolution (LTE) communication systems. 5th generation communication systems may include New Radio (NR) communication systems. The technical solution of this application can also be applied to Wireless Fidelity (WiFi) systems, communication systems supporting the convergence of multiple wireless technologies, device-to-device (D2D) systems, or vehicle-to-everything (V2X) communication systems.

[0137] The following describes the terminal equipment, network equipment, sensing management function, and positioning management function involved in this application.

[0138] Terminal equipment, also known as user equipment (UE), mobile station (MS), mobile terminal (MT), fixed wireless access (FWA), customer premises equipment (CPE), etc., refers to devices that include wireless communication capabilities (providing voice / data connectivity to users). Examples include handheld devices with wireless connectivity, in-vehicle devices, and machine-type communication (MTC) terminals. Currently, terminal devices can include: mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving (e.g., drones, vehicles), wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, and wireless terminals in smart homes. For example, wireless terminals in self-driving can be drones, helicopters, or airplanes. For example, wireless terminals in vehicle-to-everything (V2X) can be in-vehicle equipment, vehicle-mounted equipment, in-vehicle modules, vehicles, or ships. Wireless terminals in industrial control can be cameras, robots, or robotic arms. Wireless terminals in smart homes can be televisions, air conditioners, robot vacuums, speakers, or set-top boxes. The terminal device can also be a device or module that is connected to the communication system shown above and has corresponding communication functions. The terminal device usually contains a communication module, circuit or chip that performs the corresponding communication function, and the terminal device is also configured with program instructions for performing the corresponding communication function.

[0139] It should be noted that the terminal device can be a device or apparatus with a chip, or a device or apparatus with integrated circuitry, or a chip, chip system, module, or control unit in the device or apparatus shown above; this application does not limit the specific application. It should also be noted that in this application, the term "terminal device" can refer to the terminal device itself, or to the chip, functional module, or integrated circuit within the terminal device that performs the method provided in this application; this application does not limit the specific application. A network device is an apparatus deployed in a wireless access network to provide wireless communication functions for terminal devices. A network device can connect a terminal device to a radio access network (RAN) node in a wireless network, and can also be referred to as a network device, RAN entity, access node, network node, or communication device, etc.

[0140] Specifically, network equipment can be network equipment for cellular systems related to the 3rd Generation Partnership Project (3GPP). For example, 4G communication systems, 5G communication systems, or future communication systems. Network equipment can also be network equipment in open RAN (ORAN) or cloud radio access network (CRAN). Alternatively, network equipment can also be network equipment in a communication system resulting from the integration of two or more of the above communication systems.

[0141] Network equipment includes, but is not limited to: evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved Node B, or home Node B, HNB), base band unit (BBU), access point (AP) in wireless fidelity (WIFI) systems, macro base station, micro base station, wireless relay node, donor node, radio controller in CRAN scenarios, wireless backhaul node, transmission point (TP), or transmission and reception point (TRP), etc., and can also be network equipment in 5G mobile communication systems. For example, next-generation base station (gNB) in NR systems, TRP, TP; or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G mobile communication system; or, network equipment can also be network nodes constituting a gNB or transmission point. Examples include centralized unit (CU), distributed unit (DU), centralized unit control plane (CU-CP), centralized unit user plane (CU-UP), or radio unit (RU). CUs and DUs can be separate entities or included in the same network element, such as a BBU. RUs can be included in radio equipment or radio units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs). Alternatively, network equipment can be servers, wearable devices, vehicles, or in-vehicle equipment. For example, network equipment in V2X technology can be roadside units (RSUs). It should be understood that the aforementioned TRP can be a device or module located on the network side of the communication system and possessing corresponding communication functions. The TRP typically contains communication modules, circuits, or chips that perform the corresponding communication functions. The TRP can also be configured with program instructions for the corresponding communication functions.

[0142] It should be noted that CU (or CU-CP and CU-UP), DU, or RU may have different names in different systems, but those skilled in the art will understand their meaning. For example, in an Open Access Network (ORAN) system, CU can also be called an open centralized unit (O-CU) or an open CU, DU can also be called an open distributed unit (O-DU), CU-CP can also be called an open centralized unit control plane (O-CU-CP), CU-UP can also be called an open centralized unit user plane (O-CU-UP), and RU can also be called an open radio unit (O-RU). This application does not impose any specific limitations on these details. Any of the units CU, CU-CP, CU-UP, DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules.

[0143] Optionally, for network elements in the ORAN system, each network element can implement the protocol layer functions shown in Table 1 below.

[0144] Table 1

[0145] It should be noted that in the ORAN system, the network device in this application can be one or more network elements listed in Table 1 above.

[0146] The architecture of the CU and DU of a network device is described below. A network device includes at least one CU and at least one DU. Optionally, the network device may also include at least one RU.

[0147] The following example uses a network device consisting of a CU and a DU. The CU has some core network functions and can include CU-CP and CU-UP. The CU and DU can be configured according to the protocol layer functions of the wireless network they implement. For example, the CU may be configured to implement the Packet Data Convergence Protocol (PDCP) layer and above (e.g., RRC and / or SDAP layers). The DU may be configured to implement protocol layers below the PDCP layer (e.g., RLC, MAC, and / or physical (PHY) layers). Alternatively, the CU may be configured to implement protocol layers above the PDCP layer (e.g., RRC and / or SDAP layers), and the DU may be configured to implement protocol layers below the PDCP layer (e.g., RLC, MAC, and / or PHY layers).

[0148] If a CU includes CU-CP and CU-UP, CU-CP is used to implement the control plane functions of the CU, and CU-UP is used to implement the user plane functions of the CU. For example, if a CU is configured to implement the functions of the PDCP layer, RRC layer, and SDAP layer, CU-CP is used to implement the RRC layer functions and the control plane functions of the PDCP layer, and CU-UP is used to implement the SDAP layer functions and the user plane functions of the PDCP layer.

[0149] The CU-CP can interact with network elements in the core network used to implement control plane functions. These network elements can be access and mobility function (AMF) network elements, such as the AMF in a 5G system. The AMF is responsible for mobility management in the mobile network, such as terminal device location updates, terminal device registration with the network, and terminal device handover.

[0150] CU-UP can interact with network elements in the core network used to implement user plane functions. These network elements, such as the user plane function (UPF) in a 5G system, are responsible for forwarding and inputting data in terminal devices.

[0151] Optionally, the ORAN architecture also includes a RAN Intelligent Controller (RIC) module.

[0152] It should be noted that network equipment can be a device or apparatus with a chip, or a device or apparatus with integrated circuitry, or a chip, chip system, module, or control unit in the aforementioned device or apparatus; this application does not impose any specific limitation. It should also be noted that in this application, the term "network equipment" can refer to the network equipment itself, or to the chip, functional module, or integrated circuit within the network equipment that performs the methods provided in this application; this application does not impose any specific limitation.

[0153] Secondly, some technical concepts involved in the embodiments of this application will be introduced.

[0154] 1. The terms "system" and "network" in the embodiments of this application can be used interchangeably. "Multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, "at least one of A, B, and C" includes A, B, C, AB, AC, BC, or ABC. And, unless otherwise specified, the ordinal numbers such as "first" and "second" mentioned in the embodiments of this application are used to distinguish multiple objects and are not used to limit the order, sequence, priority, or importance of multiple objects.

[0155] 2. In the embodiments of this application, "output" and "input" indicate the direction of signal transmission. For example, "outputting information to XX" can be understood as the destination of the information being XX, which may include direct output via the air interface or indirect output by other units or modules via the air interface. "Inputting information from YY" can be understood as the source of the information being YY, which may include direct input from YY via the air interface or indirect input from YY via other units or modules via the air interface. "Output" can also be understood as the "output" of the chip interface, and "input" can also be understood as the "input" of the chip interface.

[0156] In other words, output and input can occur between devices, such as between network devices and terminal devices, or within a device, such as between components, modules, chips, software modules, or hardware modules within the device via buses, wiring, or interfaces.

[0157] It is understandable that information may undergo necessary processing, such as encoding and modulation, between the source and destination ends, but the destination end can understand the valid information from the source end. Similar statements in this application can be understood in a similar way, and will not be elaborated further.

[0158] In the embodiments of this application, "output" can be replaced with "send", and "input" can be replaced with "receive". The embodiments of this application do not impose any restrictions on this.

[0159] 3. In the embodiments of this application, "instruction" can include direct instruction and indirect instruction, as well as explicit instruction and implicit instruction. The information indicated by a certain piece of information (as described below, the instruction information) is called the information to be instructed. In the specific implementation process, there are many ways to indicate the information to be instructed, such as, but not limited to, directly indicating the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly indicate the information to be instructed by indicating other information, where there is a correlation between the other information and the information to be instructed; or it can only indicate a part of the information to be instructed, while the other parts are known or pre-agreed upon. For example, the instruction can be implemented by using a pre-agreed (e.g., protocol predefined) arrangement of various information, thereby reducing the instruction overhead to a certain extent. This application does not limit the specific method of instruction. It is understood that for the output party of the instruction information, the instruction information can be used to indicate the information to be instructed; for the input party of the instruction information, the instruction information can be used to determine the information to be instructed.

[0160] 4. Environment and environmental information.

[0161] The environment can also be referred to as the scene. In the embodiments of this application, the environment refers to the environment in which the transmitter or receiver is located (or situated). The environment in which the transmitter is located can be an environment determined with the transmitter's position as a reference point; similarly, the environment in which the receiver is located can be understood as an environment determined with the receiver's position as a reference point. In fact, both the environment in which the transmitter and the environment in which the receiver are located can include the transmitter and the receiver. The environment can be used to assist in locating the transmitter and the receiver. In addition to the transmitter and the receiver, the scene can also include obstacles.

[0162] Information used to indicate the environment is called environmental information. Environmental information can also be called environmental parameter information, or environmental parameter set information, etc. Environmental information indicates the environment in which the transmitter or receiver is located. Environmental information indicates obstacles in the environment. Environmental information includes at least one of the following: the number of obstacles, their location, shape, or material properties. The content of obstacles can refer to the obstacle content discussed above; repeated descriptions will not be listed again. Optionally, environmental information indicates at least one of the following: the outline and material of buildings and vegetation, the outline and location of vehicles, the location of pedestrians, or the distribution of crowds.

[0163] Environmental information can take the form of environmental map information or environmental point cloud information (such as two-dimensional, three-dimensional, or higher-dimensional point cloud information). Map information, such as a building map, can contain the coordinates of multiple edges of buildings, thus indicating the location, shape, and size of obstacles in the environment. Three-dimensional point cloud information includes, for example, a large number of points, each containing a three-dimensional coordinate and other attributes, such as point cloud intensity information or point cloud type information, indicating the object type (or material) corresponding to the point cloud.

[0164] 5. Environmental perception.

[0165] With the rapid development of wireless communication technology, base stations, as core components of networks, are constantly expanding their functions and application scenarios. In recent years, the technology of using base stations for environmental sensing has gradually attracted attention. This technology is based on the interaction between the base station and its surrounding environment, and achieves the perception and monitoring of the surrounding environment by collecting and analyzing the signals received by the base station.

[0166] In the field of environmental sensing, traditional methods typically rely on specialized sensors and equipment, such as cameras, radar, or infrared detectors. However, these methods have several drawbacks, including high cost, difficult deployment, and susceptibility to weather conditions. In contrast, utilizing base stations for environmental sensing offers numerous advantages.

[0167] Base stations offer extensive coverage. As the infrastructure of wireless communication networks, base stations typically cover entire cities or specific areas. This means that using base stations for environmental sensing enables real-time monitoring of large areas, providing valuable data support for urban planning, traffic management, disaster early warning, and other fields. Secondly, base stations are continuously online. They need to provide communication services to users 24 hours a day, so they are always operational. This allows for real-time, continuous data collection and analysis for environmental sensing, enabling timely detection and handling of environmental problems. Furthermore, using base stations for environmental sensing can reduce costs. Since base stations are already widely deployed in cities, there is no need to install a large number of additional sensors and equipment. Simply upgrading and modifying existing base stations is sufficient to achieve environmental sensing and monitoring. This not only saves significant investment costs but also avoids redundant construction and resource waste.

[0168] 6. Sensing technology.

[0169] Sensing technology refers to the use of communication networks to detect, track, and image obstacles. The underlying principles of sensing technology differ somewhat from those of communication technology. Communication technology involves the transmitter modulating information onto radio waves and sending it to the receiver, which then demodulates the signal to obtain the information. Sensing technology, however, requires the transmitter to send radio waves in a specific direction. When these radio waves strike the surface of an obstacle, they are reflected, and the receiver receives and processes these reflected waves to obtain information such as the obstacle's shape, size, location, material, speed, and type.

[0170] Sensing technologies can generally be divided into two types based on their modes: single-base sensing and dual-base sensing. In single-base sensing, the transmitting and receiving ends of the measurement signal are the same device. In terms of the measurement signal flow, the sensing station must both send the measurement signal and receive the signal reflected from the surface of the obstacle (also known as the echo signal). Therefore, the single-base sensing mode is also called the self-transmitting and self-receiving mode.

[0171] As shown in Figure 3a, which is a schematic diagram of a single-base sensing scenario, dual-base sensing involves two different devices that transmit and receive the measurement signal. In terms of the signal flow, after sensing station A transmits the measurement signal, the signal reflected from the obstacle surface is received by sensing station B. Therefore, dual-base sensing is also called the A-transmit B-receive mode, as shown in Figure 3b, which is a schematic diagram of a dual-base sensing scenario.

[0172] For ease of understanding, please refer to Figure 3c, which is a schematic diagram of a sensing scenario in an embodiment of this application. During the communication between the network device and the terminal device in Figure 3c, the network device can also sense objects that do not have communication capabilities, such as the car and the user in Figure 3c.

[0173] Furthermore, the sensing scenario illustrated in Figure 3c can be further subdivided into various sub-scenarios. For example, the sensing scenario illustrated in Figure 3d takes a network device as a base station and a terminal device as a user equipment (UE). Figure 3d is a schematic diagram of another sensing scenario in this application embodiment. The sensing scenario can specifically include: (1) The base station sends a measurement signal and receives the echo signal of the measurement signal itself; this scenario is also called the base station's self-transmission and self-reception scenario; (2) The UE sends a measurement signal and receives the echo signal of the measurement signal itself; this scenario is also called the UE's self-transmission and self-reception scenario; (3) Base station A sends a measurement signal, and base station B receives the echo signal of the measurement signal; base station A and base station B are different base stations; (4) UE A sends a measurement signal, and UE B receives the echo signal of the measurement signal; UE A and UE B are different UEs; (5) The base station sends a measurement signal, and the UE receives the echo signal of the measurement signal; (6) The UE sends a measurement signal, and the base station receives the echo signal of the measurement signal. The above scenarios (3) to (6) can also be called self-transmission and self-reception scenarios.

[0174] As described above, the transmitting and receiving ends of the measurement signals differ under different sensing modes. Each sensing mode requires its own measurement signal configuration. Therefore, it is impossible to uniformly control and flexibly schedule the measurement signals, which limits the accuracy of sensing measurements and increases communication overhead.

[0175] Based on this, embodiments of this application propose a communication method and related apparatus. A first apparatus acquires configuration information, which indicates a sensing mode and the resources of the measurement signal corresponding to that sensing mode. The first apparatus outputs a measurement signal, which is carried on the resources of the measurement signal corresponding to the sensing mode. Through the configuration information, measurement signals suitable for different sensing modes can be flexibly configured, enabling unified scheduling of measurement signals under different sensing modes, thereby improving the accuracy of sensing measurements and reducing the communication overhead of sensing measurements.

[0176] First, the communication system involved in the embodiments of this application is introduced. Please refer to Figure 4a, which is a schematic diagram of the structure of a communication system involved in the embodiments of this application. The communication system proposed in this application includes: a first device, a second device, and a third device. The second device outputs configuration information to the first and third devices. The first device outputs a measurement signal to the third device according to the configuration information. The third device inputs the measurement signal from the first device according to the configuration information. The first device, second device, and third device described above have various possible implementations, which will be further explained below with reference to the accompanying drawings.

[0177] In one example, taking a first network device as an example, please refer to Figure 4b, which is a schematic diagram of another communication system according to an embodiment of this application. In the communication system illustrated in Figure 4b, the second device can be any of the following devices (or apparatuses): a first network device, a second network device, a sensing unit, or a core network device. Exemplarily, the core network device can be a sensing function (SF), or, for example, a device that performs core network element functions. In the communication system illustrated in Figure 4b, the third device can be any of the following devices (or apparatuses): a first network device, a second network device, or a terminal device. The various scenarios illustrated in Figure 4b are described below.

[0178] Scenario 1: The first device is a first network device, the second device is a first network device, and the third device is a first network device. In other words, in this scenario, the first network device is pre-configured with configuration information, and the first network device performs spontaneous and self-receiving sensing measurements based on this configuration information.

[0179] Scenario 2: The first device is a first network device, the second device is a second network device, and the third device is a first network device. In other words, in this scenario, the first network device performs spontaneous and spontaneous sensing measurements based on the configuration information configured by the other network devices (i.e., the second network device).

[0180] Scenario 3: The first device is a first network device, the second device is a sensing unit, and the third device is the first network device. In other words, in this scenario, the first network device performs self-initiated and self-received sensing measurements based on the configuration information configured by the sensing unit.

[0181] Scenario 4: The first device is a first network device, the second device is a core network device, and the third device is a first network device. In other words, in this scenario, the first network device performs self-initiated and self-received sensing measurements based on the configuration information configured by the core network device.

[0213] It should be noted that the measurement signal input to the aforementioned network device or terminal device can be the measurement signal itself, or it can be the echo signal after the measurement signal has been scattered, reflected, refracted and / or diffracted by an obstacle. This application embodiment does not limit this.

[0214] Based on the aforementioned communication system and sensing mode, the method embodiment of this application will be described next. It is understood that this embodiment is applicable to any one or more of the aforementioned scenarios, and this application embodiment does not limit it. Please refer to Figure 6, which is a schematic flowchart of an embodiment of the communication method in this application. The communication method proposed in this application embodiment includes:

[0215] 601. The first device obtains configuration information from the second device, which indicates the sensing mode and the resources of the measurement signal corresponding to the sensing mode.

[0216] In step 601, the first device determines the resources of the measurement signal and the sensing mode corresponding to the measurement signal based on the configuration information. Then, the first device performs the sensing measurement corresponding to the sensing mode according to the configuration information. Specifically, the first device outputs the measurement signal based on the resources of the measurement signal. Exemplarily, the measurement signal in this embodiment can be a cooperative sensing reference signal (CS-RS). It should be noted that the measurement signal in this embodiment can also be other types of reference signals, and this embodiment does not limit this.

[0217] Optionally, the configuration information indicating the sensing mode and the resources of the measurement signal corresponding to the sensing mode can be replaced with: the configuration information indicating the resources of the measurement signal and the sensing mode applicable to the measurement signal; or, the configuration information indicating the resources of the measurement signal and the sensing mode corresponding to the measurement signal.

[0218] First, let's describe in detail the various types of information (or information elements) included in the above configuration information. The configuration information includes one or more of the following:

[0219] 1. First information, which can also be called sensing mode type information, indicates the sensing mode corresponding to the measurement signal. This sensing mode type information can also be called "sensingStaticType" information. For example, the relationship between the value of the first information and the sensing mode corresponding to the measurement signal indicated by the first information is shown in Table 2.

[0220] Table 2

[0221] 2. Second information, which can also be called measurement signal resource information, is used to configure the resources of the measurement signal. This measurement signal resource information can also be called "CSRS-Resource" information.

[0222] 3. Third information, which can also be called measurement signal resource set information, is used to configure resources for N measurement signals, where N is an integer greater than or equal to 1. For example, each piece of third information includes N pieces of second information. This measurement signal resource set information can also be called "CSRS-ResourceSet" information.

The output mode of the measurement signal includes any one of the following: periodic output of the measurement signal, semi-static output of the measurement signal, non-periodic output of the measurement signal, or, fixed-number repeated output of the measurement signal, wherein the fixed-number repeated output of the measurement signal means: repeatedly outputting the measurement signal K times, where K is an integer greater than or equal to 1. This resource type information can also be called "resourceType" information. For example, the relationship between the value of the fourth information and the output mode of the measurement signal indicated by the fourth information is shown in Table 3.

[0224] Table 3

[0225] 5. Fifth Information, which can also be called Physical Channel Type Information, indicates the physical channel carrying the measurement signal. The physical channel includes any one of the following: Physical Broadcast Channel (PBCH), Physical Downlink Shared Channel (PDSCH), Physical Downlink Control Channel (PDCCH), Physical Uplink Shared Channel (PUSCH), Physical Uplink Control Channel (PUCCH), Physical Side Link Shared Channel (PSSCH), Physical Side Link Control Channel (PSCCH), Physical Side Link Broadcast Channel (PSBCH), Physical Side Link Feedback Channel (PSFCH), Uplink, Downlink, Side Link, Cross Link, or Backhaul Link. This physical channel type information can also be called "physicalChannelType" information. For example, the relationship between the value of the fifth information and the physical channel carrying the measurement signal indicated by the fifth information is shown in Table 4.

[0226] Table 4

[0227] 6. Sixth Information, which can also be called bearer information, indicates the resources carrying the measurement signal. These resources include one or more of the following: first communication resources, or second communication resources. The first communication resource is carried on any of the following physical channels: Physical Broadcast Channel (PBCH), Physical Downlink Shared Channel (PDSCH), Physical Downlink Control Channel (PDCCH), Physical Uplink Shared Channel (PUSCH), Physical Uplink Control Channel (PUCCH), Physical Side Link Shared Channel (PSSCH), Physical Side Link Control Channel (PSCCH), Physical Side Link Broadcast Channel (PSBCH), and Physical Side Link Feedback Channel (PSFCH). The second communication resource is carried on any of the following physical channels: uplink, downlink, side link, cross link, or backhaul link. This bearer information can also be called "pilotOrPayload" information. For example, the relationship between the value of the sixth information and the resources carrying the measurement signal indicated by the sixth information is shown in Table 5.

[0228] Table 5

[0229] Referring to Table 5, if the value of the carrying information is 0, the carrying information indicates that the measurement signal is carried on the first communication resource; if the value of the carrying information is 1, the carrying information indicates that the measurement signal is carried on the second communication resource; if the value of the carrying information is 2, the carrying information indicates that the measurement signal is carried on both the first and second communication resources.

[0230] It should be noted that "if the value of the carrying information is 0, the carrying information indicates that the measurement signal is carried on the first communication resource" can also be expressed as: when the value of the carrying information is 0, the carrying information indicates that the measurement signal is carried on the first communication resource. Other similar expressions in the embodiments of this application can also be described in the same way, and no restrictions are imposed here.

[0231] 7. Seventh Information, which can also be called pilot type information, indicates the type of pilot signal used for multiplexing the measurement signal. The type of pilot signal includes any one or more of the following: communication pilot signal, positioning pilot signal, or sensing pilot signal. The measurement result of the communication pilot signal is used for communication, the measurement result of the positioning pilot signal is used for positioning, and the measurement result of the sensing pilot signal is used for sensing. This pilot type information can also be called "pilotType" information. For example, the values ​​of the seventh information and the type of pilot signal indicated by the seventh information for multiplexing the measurement signal are shown in Table 6.

[0232] Table 6

[0233] For example, communication pilot signals include: Channel State Information-Reference Signal (CSI-RS), Sounding Reference Signal (SRS), and / or Phase Tracking Reference Signal (PTRS). Positioning pilot signals include: Positioning Reference Signal (PRS), and / or, Positioning-Specific SRS. Sensing pilot signals refer to pilot signals that can be used for sensing measurements.

[0234] Referring to Table 6, if the pilot type information value is 0, the measurement signal can reuse the communication pilot signal. That is, the first device can use the communication pilot signal as the measurement signal; the first device does not need to actually output a measurement signal, but performs sensing measurement through the communication pilot signal. In this case, the configuration information can include only the pilot type information. Similarly, if the pilot type information value is 4, the measurement signal can reuse both the communication pilot signal and the sensing pilot signal.

[0235] 8. The eighth information, also known as network device transparent configuration information, indicates whether the network device that inputs the configuration information will transparently transmit the configuration information or not. This network device transparent configuration information can also be called "transparentToBS" information. For example, the relationship between the value of the eighth information and whether the configuration information is transparent to the network device is shown in Table 7.

[0236] Table 7

[0237] For example, the meaning of configuration information being transparent to network devices is that the network device does not read the configuration information after it is input, in order to save the processing overhead of the network device and improve privacy and security.

[0238] 9. Ninth Information, which can also be called terminal device transparent configuration information, indicates whether the terminal device that inputs the configuration information will transparently transmit the configuration information or not. This terminal device transparent configuration information can also be called "transparentToUE" information. For example, the relationship between the value of the ninth information and whether the configuration information is transparent to the terminal device is shown in Table 8.

[0239] Table 8

[0240] For example, the meaning of configuration information being transparent to the terminal device is that the terminal device does not read the configuration information after inputting it, so as to save the processing overhead of the terminal device and improve privacy and security.

[0242] Optionally, the tenth information includes: pilot resource mapping information, and / or payload resource mapping information. The pilot resource mapping information (e.g., "pilotResourceMapping" information) indicates the frequency domain resources, time domain resources, and / or antenna ports carrying the measurement signal when the communication resource carrying the measurement signal is a first communication resource (i.e., the communication resource carrying the pilot signal). The payload resource mapping information (e.g., "payloadResourceMapping" information) indicates the frequency domain resources, time domain resources, and / or antenna ports carrying the measurement signal when the communication resource carrying the measurement signal is a second communication resource (i.e., the communication resource carrying the payload).

[0243] 11. Resource set list information for measurement signals, which includes resource set information for M measurement signals, where M is an integer greater than or equal to 1. For example, this information may also be referred to as "csrs-ResourceSetList" information.

[0246] 14. Identification information of the resource set information of the measurement signal, for example, this information may also be called "csrs-ResourceSetID" information.

[0247] 15. Measurement signal resource information set, which includes N measurement signal resource information items. Each measurement signal resource information item is used to configure the resources of one or more measurement signals, where N is an integer greater than or equal to 1. The measurement signal resource information set can also be called a measurement signal resource package, or "csrs-Resources" information.

[0248] 16. Repetition parameter: The repetition parameter is used to indicate whether the resources indicated by the configuration information or the resources indicated by the resource set information are output on the same beam.

[0249] 17. Aperiodic Triggering Offset: This aperiodic triggering offset is used to indicate the time slot interval offset between the output time slot of the activation command (or trigger signal) and the output time slot of the measurement signal when the resource type of the measurement signal is aperiodic output measurement signal. When the measurement signal is output aperiodicly, the first device can only output the measurement signal once after outputting the activation command (or trigger signal).

[0250] 18. Tracking Reference Signal Information (trs-Info): The tracking reference signal information is used to indicate whether the antenna ports configured for resources with the same port index in the resource indicated by the configuration information (or the resource set information) are the same.

[0251] 19. Fixed-Number Repetition Parameter: This information is used to determine the number of times the measurement signal is repeatedly output, repeatedly measured, or transmitted when the resource type of the measurement signal is fixed-number repetition. For example, the relationship between the value of the fixed-number repetition parameter and the number of times the measurement signal is repeatedly output is shown in Table 9.

[0252] Table 9

[0253] 20. Resource identification information, such as "csrs-ResourceId".

[0254] 21. Power Control Offset, such as "powerControlOffset" information, is used to control the output power of the measured signal.

[0256] 23. Periodicity and Offset: This information, such as "periodicityAndOffset" information, indicates the output period of the measurement signal and / or the output time slot offset of the measurement signal. Specifically, when the resource type of the measurement signal is periodic output or semi-static output, this information indicates the output period of the measurement signal. Specifically, when the resource type of the measurement signal is semi-static output, this information indicates the time slot interval offset between the output time slot of the activation command (or trigger signal) and the output time slot of the measurement signal. In the case of semi-static output measurement signal, the first device can periodically output the measurement signal only after outputting the activation command (or trigger signal).

[0257] 24. Quasi-communication information (qcl-Info): This quasi-communication information indicates the quasi-communication type of the measurement signal.

The configuration information includes one or more of the following: measurement signal resource information, sensing mode type information, physical channel type information, resource type information, configuration information identification information, repeating parameters, non-periodic trigger offset, or tracking parameter signal information. The measurement signal resource information is used to configure the resources of one or more measurement signals. In other words, one or more of the information included in the configuration information takes effect on one or more measurement signals corresponding to the measurement signal resource information.

[0260] For example, the length of this perception pattern type information is 3 bits.

[0261] For example, the physical channel type information is 4 bits long.

[0262] For example, the length of this resource type information is 2 bits.

[0263] In another possible implementation, please refer to Figure 8b, which is another schematic diagram of the configuration information in an embodiment of this application.

The set of measurement signal resource information includes N resource information. M is an integer greater than or equal to 1, and N is an integer greater than or equal to 1. In other words, one or more of the information included in the configuration information takes effect on the measurement signals corresponding to the M*N measurement signal resource information indicated by the configuration information.

[0264] Optionally, the second device can first configure M*N measurement signal resource information to the first device and / or the third device at one time through configuration information, and then the second device can activate any one or more of the M*N measurement signal resource information to the first device and / or the third device through indication information, thereby realizing hierarchical configuration of measurement signal resource information.

[0266] For example, the length of the fixed number of repetition parameters is 3 to 4 bits.

[0267] For example, the length of the information carried is 2 bits.

[0268] For example, the pilot type information is 2 bits long.

[0269] For example, the length of the configuration information transparently transmitted by the network device is 1 bit.

[0270] For example, the length of the configuration information transparently transmitted by the terminal device is 1 bit.

[0271] Thirdly, the constraints between the aforementioned information types (or information elements) are described.

Referring to Figure 10, the sensing mode type information determines the bearer information, physical channel type information, resource type information, network device transparent transmission configuration information, and terminal device transparent transmission configuration information. The bearer information determines the pilot type information, the pilot resource mapping information, and the payload resource mapping information. The resource type information determines the non-periodic trigger offset, the periodicity, and the offset and fixed-number repetition parameters.

[0272] Referring to Figure 10, a constraint relationship is shown in Figure 11, which is another schematic diagram of the constraint relationship in an embodiment of this application.

[0301] 602. The third device obtains configuration information from the second device, which indicates the sensing mode and the resources of the measurement signal corresponding to the sensing mode.

[0302] In step 602, after obtaining configuration information from the second device, the third device determines the resources for the input measurement signal based on the configuration information. For details regarding the configuration information, please refer to the description of step 601; it will not be repeated here.

[0303] 603. The first device outputs a measurement signal to the third device, and the measurement signal carries the resources of the measurement signal corresponding to the sensing mode.

[0304] Following steps 601 and 602, in step 603, the first device outputs a measurement signal to the third device based on the configuration information. This measurement signal carries the resources of the measurement signal corresponding to the sensing mode indicated by the configuration information. Accordingly, the third device determines the measurement result of the measurement signal based on this measurement signal.

[0305] The following are several example scenarios:

[0306] In one example scenario, if both the first device and the third device are first network devices, the value of the perception mode type information in the configuration information is 0, and the configuration information indicates that the perception mode is perception mode 0, that is, the output direction of the measurement signal is self-transmission and self-reception of the base station.

[0307] In another example scenario, if the first device is a first network device and the third device is a second network device, and the first network device is different from the second network device, the value of the perception mode type information in the configuration information is 1, and the configuration information indicates that the perception mode is perception mode 1, that is, the output direction of the measurement signal is base station A transmitting and base station B receiving.

[0308] In another example scenario, if the first device is a first network device and the third device is a terminal device, the value of the perception mode type information in the configuration information is 2, and the configuration information indicates that the perception mode is perception mode 2, that is, the output direction of the measurement signal is base station transmission and UE reception.

[0309] In another example scenario, if the first device is a terminal device and the third device is a network device, the value of the perception mode type information in the configuration information is 3, and the configuration information indicates that the perception mode is perception mode 3, that is, the output direction of the measurement signal is UE transmission and base station reception.

[0310] In another example scenario, if both the first device and the third device are first terminal devices, the value of the perception mode type information in the configuration information is 4, and the configuration information indicates that the perception mode is perception mode 4, that is, the output direction of the measurement signal is UE self-transmission and self-reception.

[0311] In another example scenario, if the first device is the first terminal device and the third device is the second terminal device, the value of the perception mode type information in the configuration information is 5, and the configuration information indicates that the perception mode is perception mode 5, that is, the output direction of the measurement signal is UE A sending and UE B receiving.

[0312] In another example scenario, if the resource type information of the configuration information is 0, the first device determines that the output mode of the measurement signal is to periodically output the measurement signal based on the resource type information. In this case, the first device does not need to output an additional activation command (or trigger signal) before determining the output measurement signal.

[0313] In another example scenario, if the resource type information in the configuration information is 1 or 2, and the first device determines based on this resource type information whether the output mode of the measurement signal is a semi-static output measurement signal or a non-periodic output measurement signal, then the first device needs to output an activation command (or trigger signal) before outputting the measurement signal. Only after the first device outputs the activation command (or trigger signal) can the first device output the measurement signal so that the third device can input the measurement signal in response to the activation command (or trigger signal).

[0314] In another example scenario, if the resource type information in the configuration information is 3, and the first device determines that the output method of the measurement signal is to repeatedly output the measurement signal a fixed number of times based on the resource type information, then the first device can output an activation command (or trigger signal) before outputting the measurement signal, or the first device does not need to output an activation command (or trigger signal) before outputting the measurement signal.

[0315] Through the above technical solutions, the integrated sensing and communication (ISAC) network can achieve unified control and flexible scheduling of various sensing modes. By configuring information, measurement signals can be measured under multiple sensing modes to leverage the advantages of different sensing modes and compensate for the shortcomings of a single sensing mode. Ultimately, the ISAC network can achieve the effects of increasing sensing range, improving sensing accuracy, and optimizing sensing overhead. Configuration information also allows for flexible configuration of measurement signals suitable for different sensing modes, enabling unified scheduling of measurement signals under different sensing modes to improve the accuracy of sensing measurements and reduce communication overhead.

[0316] Based on the foregoing embodiments, the following describes different output methods of the measurement signal. Please refer to Figure 7, which is a schematic diagram of the output methods of the measurement signal in the embodiments of this application. Specifically, the output methods of the measurement signal in the embodiments of this application may include: periodic output of the measurement signal, semi-static output of the measurement signal, non-periodic output of the measurement signal, and output of the measurement signal with a fixed number of repetitions. These will be described below with reference to Figure 7.

[0317] First, step 701 is executed, where the first device and the third device respectively acquire configuration information. Following step 701, the following steps are specifically executed:

[0318] If the output mode of the measurement signal is to periodically output the measurement signal, step 702 is executed after step 701: the first device periodically outputs the measurement signal to the third device.

[0319] If the measurement signal output mode is semi-static output measurement signal, then after step 701, steps 703 to 705 are executed:

[0320] 703. The first device outputs the first activation command to the third device.

[0321] 704. In response to the first activation command, the first device periodically outputs a measurement signal to the third device. Correspondingly, the third device, in response to the first activation command, inputs the measurement signal.

[0322] 705. If the first device needs to stop outputting the measurement signal, the first device outputs a deactivation command to the third device. Accordingly, the third device responds to the deactivation command and stops inputting the measurement signal.

[0323] If the output mode of the measurement signal is a non-periodic output measurement signal, then after step 701, steps 706 to 707 are executed:

[0324] 706. The first device outputs the first activation command to the third device.

[0325] 707. In response to the first activation command, the first device outputs a measurement signal to the third device. Correspondingly, the third device, in response to the first activation command, inputs the measurement signal.

[0326] If the measurement signal is output in a fixed repetition rate, steps 708 to 709 are executed after step 701, or step 710 is executed after step 701:

[0327] Specifically, the output method of the measurement signal is to output the measurement signal with a fixed number of repetitions. This can include two methods: Method 1 and Method 2.

[0328] Method 1: 708. The first device outputs a second activation command to the third device.

[0329] 709. In response to the second activation command, the first device repeatedly outputs the measurement signal K times to the third device. Correspondingly, the third device, in response to the second activation command, inputs the measurement signal.

[0330] In step 709, the first device can also determine the time-domain offset between the K repeatedly output measurement signals and the second activation command based on the periodicity and offset in the configuration information.

[0331] Method 2: 710. The first device repeatedly outputs measurement signals to the third device K times.
