A communication method and related apparatus

[0001] This application claims priority to Chinese Patent Application No. 202411794978.X, filed on December 6, 2024, entitled “A Communication Method and Related Device”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to a communication method and related apparatus. Background Technology

[0003] Wireless communication can be a transmission communication between two or more communication nodes that does not propagate through conductors or cables. These communication nodes can generally include network devices and terminal devices.

[0004] Currently, in wireless communication systems, network devices can calculate and determine signal transmission resources, such as time-domain resources and frequency-domain resources used to carry the signal. Correspondingly, terminal devices can transmit and receive signals on these transmission resources. In this way, different communication devices can transmit service data related to communication services through the communication system to obtain communication services. Generally, the signal transmitted during communication may include a reference signal, which may have a known amplitude and / or phase. The receiver of the reference signal can perform measurements based on the received reference signal.

[0005] However, how to save resource consumption during the transmission of reference signals is a hot topic in the field of communications. Summary of the Invention

[0006] This application provides a communication method and related apparatus for enabling the sensing function of a communication device to achieve sensing.

[0007] The first aspect of this application provides a communication method applied to a first communication device. For example, the first communication device may be a communication equipment (such as a terminal device), or it may be a component of the communication equipment (such as a processor, circuit, chip, or chip system responsible for communication functions), or it may be a logic module or software capable of implementing all or part of the functions of the communication equipment. The following description uses a first communication device as an example. In this method, the first communication device receives first information, which is used to configure a first reference signal. The first reference signal is used for sensing and measurement. The first reference signal is a channel state information reference signal (CSI-RS), a tracking reference signal (TRS), or a sounding reference signal (SRS). The first communication device receives or transmits the first reference signal based on the first information.

[0008] Based on the above scheme, the first information received by the first communication device is used to configure a first reference signal, which is used for sensing measurement. Subsequently, the first communication device can receive or transmit the first reference signal, enabling the receiver of the first reference signal to obtain the sensing measurement result, thereby enabling the sensing function of the communication device and achieving sensing. Furthermore, the first reference signal used for sensing measurement can be CSI-RS, TRS, or SRS, and these reference signals can be used for other functions. For example, CSI-RS can be used for one or more of channel measurement, beam management, or mobility management; TRS is used for time-frequency offset measurement; and SRS is used for uplink channel measurement and / or uplink beam management. Thus, in the above scheme, the communication device can use a first reference signal with other functions for sensing measurement, achieving sensing measurement without increasing the type of reference signal, while also saving resource overhead and improving sensing performance.

[0009] It should be noted that the first communication device can receive the first reference signal based on the first information and determine the sensing measurement result based on the received first reference signal. Alternatively, the first communication device can send the first reference signal based on the first information, so that the receiver of the first reference signal determines the sensing measurement result based on the received first reference signal.

[0010] Optionally, the reference signal may have a known amplitude and / or phase. The reference signal may be referred to as a pilot, pilot signal, or reference signal, etc.

[0011] Optionally, the first reference signal is used for sensing measurement, which can be understood as at least one of the following: the first reference signal has the function of sensing measurement; the first reference signal is used to determine the sensing measurement result; the measurement report corresponding to the first reference signal contains the sensing measurement result; or, the function of the first reference signal includes at least sensing.

[0012] For example, the reference signal used for sensing (e.g., a first reference signal) can be used to sense (or reflect) one or more of the following: obstacle information in physical space, transmission channel information formed by collisions with obstacles, or transmission path information. The sensing involved in this application includes, but is not limited to, one or more of the following: positioning, measurement, detection, channel sensing, monitoring, tracking, time measurement, distance measurement, angle measurement, velocity measurement, Doppler frequency shift measurement, point cloud measurement, or sensing feedback.

[0013] In one possible implementation of the first aspect, the first information includes first indication information indicating that the sensing measurement result of the first reference signal contains Doppler information and / or time delay information; and / or, second indication information indicating resource pattern information of the first reference signal.

[0014] Based on the above scheme, the first communication device can obtain one or more of the above configurations based on the first information in order to receive or transmit the first reference signal.

[0015] As another example, if the first information includes first indication information, the first communication device can determine through the first indication information that the sensing measurement result of the first reference signal contains Doppler information and / or time delay information, and then the sensing can be realized through the Doppler information and / or time delay information.

[0016] As another example, when the first information includes the second indication information, the first communication device can determine the resource pattern information of the first reference signal through the second indication information, and can realize flexible configuration of the resource pattern information of the first reference signal.

[0017] For example, the resource pattern information indicates the starting position of the subcarrier occupied by the first reference signal, and / or, the resource pattern information indicates that the number of consecutive resource units occupied by the first reference signal within a resource block includes 6 or 12. In this way, resource pattern information adapted to the characteristics of sensing services can be provided to improve sensing performance.

[0018] Optionally, the aforementioned resource block can be a resource block (RB) or another name defined by the network in the future.

[0019] Optionally, the sensing measurement results of the first reference signal include at least one of time delay information, Doppler information, precoding information, channel rank information, and resource information of the synchronization signal block.

[0020] In one possible implementation of the first aspect, the method further includes: the first communication device transmitting second information, the second information including the sensing measurement result of the first reference signal.

[0021] Based on the above scheme, after receiving the first reference signal based on the first information, the first communication device can also send the second information, so that the receiver of the second information can obtain the sensing measurement result of the first reference signal, so as to realize multi-node collaborative sensing (e.g., bi-static sensing).

[0022] Optionally, the first communication device can determine the sensing measurement result based on the received first reference signal to achieve sensing. For example, the first reference signal can be a reference signal sent by another communication device to achieve bi-static sensing with one transmitter and one receiver. Alternatively, the first reference signal can be a reference signal sent by the first communication device to achieve mono-static sensing with self-transmission and self-reception.

[0023] In one possible implementation of the first aspect, the second information further includes third indication information, which indicates that the second information contains the sensing measurement result.

[0024] Based on the above scheme, the second information sent by the first communication device may also include third indication information, so that the recipient of the second information can determine that the second information contains the sensing measurement result and obtain the sensing measurement result from the second information to realize sensing.

[0025] In one possible implementation of the first aspect, the second information further includes at least one of the following: channel measurement results, beam management measurement results, mobility measurement results, time-frequency tracking measurement results, or positioning measurement results of the first reference signal.

[0026] Based on the above scheme, in addition to its use for sensing and measurement, the first reference signal can also be used for other functions. Correspondingly, the second information can also include measurement results corresponding to other functions, allowing the same reference signal to be reused to achieve multiple functions and improve resource utilization. Furthermore, the second information can carry other measurement results besides the sensing and measurement results, increasing the amount of information carried by the second information. This allows the receiver of the second information to obtain both the sensing and measurement results and the other measurement results in a single transmission, further improving resource utilization.

[0027] In one possible implementation of the first aspect, the first information further includes fourth indication information, which indicates at least one of the channel measurement results, beam management measurement results, mobility measurement results, time-frequency tracking measurement results, or positioning measurement results of the first reference signal, and is transmitted via the same message / information / signaling as the sensing measurement results of the first reference signal.

[0028] Based on the above scheme, the first information may also include a fourth indication information, enabling the first communication device to send different measurement results through the same message / information / signaling (e.g., the second information) based on the indication of the fourth indication information, so as to improve resource utilization.

[0029] In one possible implementation of the first aspect, the method further includes: the first communication device transmitting third information, the third information including at least one of channel measurement results, beam management measurement results, mobility measurement results, time-frequency tracking measurement results, or positioning measurement results of the first reference signal.

[0030] Based on the above scheme, in addition to its use for sensing measurement, the first reference signal can also be used for other functions. Correspondingly, the third information sent by the first communication device can also include measurement results corresponding to other functions, thus reusing the same reference signal to achieve multiple functions and improve resource utilization. Furthermore, the second information can carry sensing measurement results, while the third information can carry other measurement results besides the sensing measurement results. This allows for the transmission of sensing measurement results and communication-related measurement results through different information, enabling the transmission of measurement results for different service types and improving the flexibility of the scheme (for example, the recipients of the second and third information may not be the same communication device). Moreover, transmitting sensing measurement results and communication-related measurement results through different information allows different measurement results to be transmitted using multiple smaller resources, reducing limitations on the transmission resources for measurement results and avoiding or minimizing situations where measurement results cannot be successfully transmitted due to limitations in transmission resource size.

[0031] In one possible implementation of the first aspect, the first information further includes fifth indication information, which indicates at least one of the channel measurement results, beam management measurement results, mobility measurement results, time-frequency tracking measurement results, or positioning measurement results of the first reference signal, and is transmitted through different information than the sensing measurement results of the first reference signal.

[0032] Based on the above scheme, the first information may also include a fifth indication information, enabling the first communication device to send different measurement results through different messages / information / signaling (e.g., the second information and the third information) based on the indication of the fifth indication information.

[0033] In one possible implementation of the first aspect, the reference signal sequence of the first reference signal is associated with the radio frame index occupied by the first reference signal.

[0034] Based on the above scheme, the reference signal sequence of the first reference signal can be associated with the radio frame index occupied by the first reference signal, so that the first reference signal can be transmitted across radio frames. Since the sensing service has continuity, that is, the accumulation of sensing measurement results at different times can improve the performance of sensing measurement, the sensing performance can be improved by transmitting the first reference signal across radio frames.

[0035] Optionally, the reference signal sequence of the first reference signal is obtained based on the initialization sequence, which satisfies:

[0036] Among them, c init This indicates the initialization sequence. Indicates the number of symbols contained in a time slot. This indicates the slot number of the k-th frame when the subcarrier spacing is configured as μ. The subscript 's' represents the slot, 'f' represents the frame, 'k' represents the frame index, 'l' represents the index of the orthogonal frequency division multiplexing (OFDM) symbol within the slot, and 'n' represents the subcarrier spacing. ID This represents the cell identifier, and mod represents the remainder.

[0037] A second aspect of this application provides a communication method applied to a second communication device. For example, the second communication device may be a communication equipment (such as a network device), or it may be a component of the communication equipment (e.g., a processor, circuit, chip, or chip system responsible for communication functions). Alternatively, the second communication device may be a logic module or software capable of implementing all or part of the functions of the communication equipment. The following description uses a second communication device as an example. In this method, the second communication device sends first information, which is used to configure a first reference signal. The first reference signal is used for sensing and measurement, and it may be a channel state information reference signal, a tracking reference signal, or a detection reference signal. The second communication device receives or transmits the first reference signal based on the first information.

[0038] Based on the above scheme, the first information sent by the second communication device to the first communication device is used to configure a first reference signal, which is used for sensing measurement. Subsequently, the first communication device can receive or transmit the first reference signal, enabling the receiver of the first reference signal to obtain the sensing measurement result, thereby enabling the sensing function of the communication device and achieving sensing. Furthermore, the first reference signal used for sensing measurement can be CSI-RS, TRS, or SRS, and these reference signals can be used for other functions. For example, CSI-RS can be used for one or more of channel measurement, beam management, or mobility management; TRS is used for time-frequency offset measurement; and SRS is used for uplink channel measurement and / or uplink beam management. Thus, in the above scheme, the communication device can use a first reference signal with other functions for sensing measurement, achieving sensing measurement without increasing the type of reference signal, while also saving resource overhead and improving sensing performance.

[0039] In one possible implementation of the second aspect, the first information includes first indication information indicating that the sensing measurement result of the first reference signal contains Doppler information and / or time delay information; and / or, second indication information indicating resource pattern information of the first reference signal.

[0040] Based on the above scheme, the first communication device can obtain one or more of the above configurations based on the first information in order to receive or transmit the first reference signal.

[0055] In one possible implementation of the second aspect, the reference signal sequence of the first reference signal is associated with the radio frame index occupied by the first reference signal.

[0056] Based on the above scheme, the reference signal sequence of the first reference signal can be associated with the radio frame index occupied by the first reference signal, so that the first reference signal can be transmitted across radio frames. Since the sensing service has continuity, that is, the accumulation of sensing measurement results at different times can improve the performance of sensing measurement, the sensing performance can be improved by transmitting the first reference signal across radio frames.

[0057] Optionally, the reference signal sequence of the first reference signal is obtained based on the initialization sequence, which satisfies:

[0058] Among them, c init This indicates the initialization sequence. Indicates the number of symbols contained in a time slot.

The subscript s represents the slot, f represents the frame, k represents the frame index, l represents the index of the OFDM symbol within the slot, and n ID This represents the cell identifier, and mod represents the remainder.

[0059] A third aspect of this application provides a communication method applied to a first communication device. For example, the first communication device may be a communication equipment (such as a terminal device or network device), or it may be a component within a communication equipment (such as a processor, circuit, chip, or chip system responsible for communication functions), or it may be a logic module or software capable of implementing all or part of the functions of the communication equipment. The following description uses a first communication device as an example. In this method, the first communication device receives fourth information, which is used to configure a second reference signal. This second reference signal is used for beam management measurement and is a positioning reference signal (PRS). The first communication device receives the second reference signal based on the fourth information.

[0060] Based on the above scheme, the fourth information received by the first communication device is used to configure a second reference signal, which is used for beam management measurement. This second reference signal is a PRS (Pressure Signal Representation). Subsequently, the first communication device can receive or transmit the second reference signal, enabling the receiver of the second reference signal to obtain the beam management measurement result through the PRS. Therefore, in the above scheme, the communication device can use a second reference signal with other functions to perform beam management measurement, achieving beam management measurement without increasing the type of reference signal, while also saving resource overhead.

[0061] Optionally, the second reference signal can also be used for other functions, including but not limited to at least one of positioning measurement, sensing measurement, channel measurement, mobility measurement, or time-frequency tracking measurement. Thus, the communication device can use the second reference signal with more functions for beam management measurement, achieving beam management measurement without increasing the type of reference signal, while also saving resource overhead.

[0062] It should be noted that the first communication device can receive the second reference signal based on the fourth information and determine the beam management measurement result based on the received second reference signal.

That is, the fifth information may carry beam management measurement results and at least one other measurement result, thereby increasing the amount of information carried by the fifth information. This allows the receiver of the fifth information to obtain the beam management measurement results and the other at least one measurement result in a single transmission, improving resource utilization. Optionally, the fourth information may further include seventh indication information, which is used to instruct the beam management measurement results and the other at least one measurement result to be sent through the same message / information / signaling.

[0097] First, some terms used in the embodiments of this application will be explained to facilitate understanding by those skilled in the art.

[0098] (1) Terminal device: can be a wireless terminal device that can receive network device scheduling and instruction information. The wireless terminal device can be a device that provides voice and / or data connectivity to the user, or a handheld device with wireless connection function, or other processing device connected to a wireless modem.

[0099] Terminal devices can communicate with one or more core networks or the Internet via a radio access network (RAN). Terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones), computers, and data cards. For example, they can be portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the RAN. Examples include personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), tablets, and computers with wireless transceiver capabilities. Wireless terminal equipment can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile station (MS), remote station, access point (AP), remote terminal, access terminal, user terminal, user agent, subscriber station (SS), customer premises equipment (CPE), terminal, user equipment (UE), mobile terminal (MT), drone, etc. Terminal equipment can also be wearable devices and next-generation communication systems, such as terminal equipment in 5G communication systems or terminal equipment in future public land mobile networks (PLMNs).

[0100] (2) Network equipment (or network element): This can be equipment in a wireless network. For example, network equipment can be a RAN node (or device) that connects terminal devices to the wireless network, and can also be called a base station. Currently, some examples of RAN equipment include: base station, evolved NodeB (eNodeB), gNB (gNodeB) in 5G communication systems, transmission reception point (TRP), evolved Node B (eNB), radio network controller (RNC), Node B (NB), home base station (e.g., home evolved Node B, or home Node B, HNB), base band unit (BBU), or wireless fidelity (Wi-Fi) access point (AP), etc. In addition, in a network structure, network equipment can include centralized unit (CU) nodes, distributed unit (DU) nodes, or RAN equipment including CU nodes and DU nodes.

[0101] Optionally, RAN nodes can also be macro base stations, micro base stations, indoor stations, relay nodes, donor nodes, or radio controllers in cloud radio access network (CRAN) scenarios. RAN nodes can also be servers, wearable devices, vehicles, or in-vehicle equipment. For example, the access network equipment in V2X technology can be a roadside unit (RSU).

[0102] In this embodiment, network equipment can be deployed on satellites or on the ground. For example, a base station can be deployed entirely on a satellite, or only some of its functions can be deployed on a satellite. For instance, the radio frequency unit (RU) of a base station can be deployed on a satellite, while other parts can be deployed on the ground. Another example is that the RU and DU of a base station can be deployed on a satellite, while the CU can be deployed on the ground. Similarly, core network equipment can also be deployed on satellites. For example, some core network user plane elements can be deployed on satellites to support direct interaction between terminals via satellite, eliminating the need for ground-based communication. Some core network control plane elements can also be deployed on satellites. For example, deploying mobility management and session management elements on satellites can support emergency disaster relief services in situations where there is no terrestrial network.

[0103] For example, network devices may be deployed on non-terrestrial platforms, including but not limited to low-Earth orbit satellites, medium-Earth orbit satellites, high-Earth orbit satellites, high-altitude platforms, drones, and other high-altitude platforms.

[0104] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, with each RAN node performing a portion of the base station's functions. For example, RAN nodes can be central units (CUs), distributed units (DUs), CU-control plane (CPs), CU-user plane (UPs), or radio units (RUs), etc. CUs and DUs can be separate entities or included in the same network element, such as a baseband unit (BBU). RUs can be included in radio frequency equipment or radio frequency units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs).

[0105] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an open access network (open RAN, O-RAN, or ORAN) system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software modules and hardware modules.

[0106] Communication between access network devices and terminal devices follows a specific protocol layer structure. This protocol layer may include a control plane protocol layer and a user plane protocol layer. The control plane protocol layer may include at least one of the following: radio resource control (RRC) layer, packet data convergence protocol (PDCP) layer, radio link control (RLC) layer, medium access control (MAC) layer, or physical (PHY) layer, etc. The user plane protocol layer may include at least one of the following: service data adaptation protocol (SDAP) layer, PDCP layer, RLC layer, MAC layer, or physical layer, etc.

[0107] The correspondence between network elements and their achievable protocol layer functions in the ORAN system can be found in Table 1 below.

[0108] Table 1

[0109] Network devices can be other devices that provide wireless communication functions for terminal devices. The embodiments of this application do not limit the specific technology or form of the network device. For ease of description, the embodiments of this application are not limited.

[0110] Network equipment may also include core network equipment, such as the Mobility Management Entity (MME), Home Subscriber Server (HSS), Serving Gateway (S-GW), Policy and Charging Rules Function (PCRF), and Public Data Network Gateway (PDN Gateway, P-GW) in 4th generation (4G) networks; and AMF, User Plane Function (UPF), or Session Management Function (SMF) in 5G networks. Furthermore, this core network equipment may also include other core network equipment in 5G networks and next-generation networks of 5G networks.

[0111] In this application embodiment, the device for implementing the function of the network device can be the network device itself, or it can be a device capable of supporting the network device in implementing that function, such as a chip system, which can be installed in the network device. In the technical solutions provided in this application embodiment, the example of a network device being used to implement the function of the network device is used to describe the technical solutions provided in this application embodiment.

[0112] (3) Configuration and Pre-configuration: In this application, both configuration and pre-configuration are used. Configuration refers to the network device sending configuration information or parameter values ​​of some parameters to the terminal device through messages or signaling, so that the terminal device can determine the communication parameters or resources during transmission based on these values ​​or information. Pre-configuration is similar to configuration; it can be parameter information or parameter values ​​that the network device and the terminal device have negotiated in advance, or it can be parameter information or parameter values ​​that the network device or the terminal device uses as specified by the standard protocol, or it can be parameter information or parameter values ​​that are pre-stored in the network device or the terminal device. This application does not limit this.

[0113] Furthermore, these values ​​and parameters can be changed or updated.

[0114] (4) The terms "system" and "network" in the embodiments of this application can be used interchangeably. "At least one" means one or more, and "more" means 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 mean: A exists alone, A and B exist simultaneously, or B exists 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.

[0115] (5) In the embodiments of this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which may include sending directly through the air interface or sending indirectly through the air interface by other units or modules. "Receive information from YY" can be understood as the source of the information being YY, which may include receiving directly from YY through the air interface or receiving indirectly from YY through the air interface by other units or modules. "Send" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface.

[0116] In other words, sending and receiving 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.

[0117] It is understandable that information may undergo necessary processing, such as encoding and modulation, between the source and destination, but the destination can understand the valid information from the source. Similar statements in this application can be interpreted in a similar way and will not be elaborated further.

[0118] (6) In the embodiments of this application, "instruction" may 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 an association 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 of the information to be instructed are known or pre-agreed upon. For example, the instruction can be implemented by using a pre-agreed (e.g., protocol predefined) arrangement order 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 sender of the instruction information, the instruction information can be used to indicate the information to be instructed, and for the receiver of the instruction information, the instruction information can be used to determine the information to be instructed.

[0119] (7) Reference signal (RS), also known as pilot signal. In communication systems, estimating the uplink or downlink channel is essential for transmitting and receiving data, obtaining system synchronization and feedback channel information. Channel estimation refers to the process of reconstructing or recovering the received signal to compensate for signal distortion caused by channel fading and noise fading. It uses reference signals known to the transmitter and receiver to track the time and frequency domain changes of the channel. These reference signals are distributed in different resource elements (REs) in the time-frequency two-dimensional space within the orthogonal frequency division multiplexing (OFDM) symbols, and have known amplitudes and phases.

[0120] For example, at the physical layer, uplink communication can include the transmission of uplink physical channels and uplink signals. Uplink physical channels include random access channels (PRACH), physical uplink control channels (PUCCH), and physical uplink shared channels (PUSCH), etc. Uplink signals include sounding reference signals (SRS), PUCCH de-modulation reference signals (PUCCH-DMRS), PUSCH de-modulation reference signals (PUSCH-DMRS), uplink phase noise tracking reference signals (PTRS), and uplink positioning signals (RS), etc.

[0121] For example, at the physical layer, downlink communication can include the transmission of downlink physical channels and downlink signals. Downlink physical channels include the physical broadcast channel (PBCH), the physical downlink control channel (PDCCH), and the physical downlink shared channel (PDSCH), etc. Downlink signals include the primary synchronization signal (PSS) / secondary synchronization signal (SSS), the downlink control channel demodulation reference signal (PDCCH-DMRS), the downlink data channel demodulation reference signal (PDSCH-DMRS), the phase noise tracking signal (PTRS), the channel status information reference signal (CSI-RS), the cell reference signal (CRS), the tracking reference signal (TRS), and the positioning signal (RS), etc.

[0122] In this application, unless otherwise specified, the same or similar parts between the various embodiments can be referred to each other. In the various embodiments of this application, and in the various implementation methods / methods / implementations within each embodiment, unless otherwise specified or logically conflicting, the terminology and / or descriptions between different embodiments and between the various implementation methods / methods / implementations within each embodiment are consistent and can be mutually referenced. The technical features in different embodiments and the various implementation methods / methods / implementations within each embodiment can be combined according to their inherent logical relationships to form new embodiments, implementation methods, methods, or implementation approaches. The embodiments described below do not constitute a limitation on the scope of protection of this application.

[0123] To facilitate understanding of the methods provided in the embodiments of this application, the system architecture of the methods provided in the embodiments of this application will be described below. It is understood that the system architecture described in the embodiments of this application is for the purpose of more clearly illustrating the solutions of the embodiments of this application and does not constitute a limitation on the solutions provided in the embodiments of this application.

[0124] Please refer to Figure 1a, which is a schematic diagram of the architecture of the communication system 1000 used in the embodiments of this application. As shown in Figure 1a, the communication system includes a RAN 100 and a core network 200. Optionally, the communication system 1000 may also include an Internet 300. The RAN 100 includes at least one RAN node (110a and 110b in Figure 1a, collectively referred to as 110), and may also include at least one terminal (120a-120j in Figure 1a, collectively referred to as 120). The RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 1a). The terminal 120 is wirelessly connected to the RAN node 110, and the RAN node 110 is wirelessly or wiredly connected to the core network 200. The core network equipment in the core network 200 and the RAN node 110 in the RAN 100 can be independent and different physical devices, or they can be the same physical device integrating the logical functions of the core network equipment and the logical functions of the RAN node. Terminals can be connected to each other, as can RAN nodes, via wired or wireless means.

[0125] The core network equipment that may be involved in this application includes:

[0126] Access and mobility management function (AMF) devices / network elements / entities are deployed in the wireless core network to manage the access and mobility of terminal devices, performing registration, connection, reachability, and mobility management. AMF can also provide a session management message transmission channel for terminal devices and session management function (SMF) network elements, providing authentication and authorization functions for user access, and serving as an access point for the terminal and the wireless core network control plane.

[0127] User plane function (UPF) devices / network elements / entities refer to the user plane, which carries data traffic and is responsible for forwarding traffic between the radio access network and the Internet, reporting traffic usage, and enforcing quality of service (QoS) policies.

[0128] Figure 1b illustrates an example of an O-RAN system, which may include components other than those shown in the figure. As shown, the access network device (RAN, such as an eNB, gNB, or next-generation access network device) communicates with the core network (CN) via a backhaul link and with the UE via an air interface.

[0129] In one possible implementation, this application can be applied to long-term evolution (LTE) wireless communication systems, NR wireless communication systems, and future new radio (NR) wireless communication systems. For example, this application can be applied to orthogonal frequency division multiplexing (OFDM) systems in LTE, OFDM systems in NR, future OFDM systems, and OFDM-like systems.

[0130] This application may also involve sensing, in which wireless sensing fusion is one of the key technologies in current communication network research and can be widely used in typical application scenarios such as intelligent transportation, intelligent low-altitude airspace, and intelligent networks. Communication sensing fusion achieves unified design of communication and sensing functions through signal joint design and hardware sharing. Sensing in communication sensing fusion can be understood as wireless sensing technology based on a communication system. For example, terminal devices or network devices transmit wireless signals to a target area or object and receive the echo signals reflected by the object. By analyzing the received signals, corresponding sensing measurements are obtained, such as the number, location, speed, and identification of the target object. In other words, with the development of communication technology, future communication systems may provide sensing services in addition to communication services. Such networks can be understood as integrated sensing and communication (ISAC) networks.

[0131] As an example, taking access network devices and / or terminal devices as sensing devices, sensing signals may be transmitted between access network devices and terminal devices, between terminal devices, and between access network devices. The following will be described in conjunction with the process shown in Figure 2, with the target object being a vehicle as an example.

[0132] As shown in Figure 2, the sensing signal can have the following six modes:

[0133] (a) The access network device sends a sensing signal, and the access network device receives the sensing signal.

[0134] (b) The terminal device sends a sensing signal, and the terminal device receives the sensing signal.

[0135] (c) One access network device sends a sensing signal, and another access network device receives the sensing signal.

[0136] (d) One terminal device sends a sensing signal, and another terminal device receives the sensing signal.

[0137] (e) The access network device sends a sensing signal, and the terminal device receives the sensing signal.

[0138] (f) The terminal device sends a sensing signal, and the access network device receives the sensing signal.

[0139] Among them, modes (a) and (b) can be sensed by a single device, which can be understood as spontaneous and self-receiving mono-static sensing; modes (c) to (f) can be sensed by two devices, which can be understood as bi-static sensing.

[0140] In a wireless communication system (such as the communication system shown in Figure 1a), network devices can calculate and determine signal transmission resources, which may include time-domain resources, frequency-domain resources, etc., for carrying signals. Correspondingly, terminal devices can transmit and receive signals on these transmission resources. In this way, different communication devices can transmit service data related to communication services through the communication system to obtain communication services. Generally, the signal transmitted during communication may include a reference signal, which may have a known amplitude and / or phase. The receiver of the reference signal can perform measurements based on the received reference signal.

[0141] However, how to save resource consumption during the transmission of reference signals is a hot topic in the field of communications.

[0142] As an example, the current network has defined some reference signals and their functions, which will be illustrated in Table 2 below.

[0143] Table 2

[0144] As shown in Table 2, the relevant functions of each reference signal have been defined. In this case, how to reduce the resource overhead of the reference signals is an urgent problem to be solved.

[0145] To address the aforementioned problems, this application provides a communication method and related apparatus, which will be described in detail below with reference to the accompanying drawings.

[0146] Please refer to Figure 3, which is a schematic diagram of an implementation of the communication method provided in this application. The method includes the following steps.

[0147] It should be noted that in Figures 3 and 5 and related implementation examples below, the method is illustrated using a first communication device and other communication devices (such as a second communication device) as the execution subjects of this interaction illustration. However, this application does not limit the execution subjects of this interaction illustration. For example, the first communication device can be a terminal device, or a chip, baseband chip, modem chip, system-on-chip (SoC) chip containing a modem core, system-in-package (SIP) chip, communication module, chip system, processor, logic module, or software in the terminal device. Exemplarily, the first communication device can be a terminal device, and the second communication device can be a network device.

[0148] As an example, network equipment can be a base station or an access network device.

[0149] As another example, the second communication device can be an ORAN device (including at least one of O-CU, O-DU, and O-RU). For instance, the second communication device may include an O-RU, which can transmit first information via a wireless link, causing the first communication device to receive the first information in step S301. Alternatively, the second communication device may include an O-CU and / or an O-DU, and transmit the first information via the O-RU, causing the first communication device to receive the first information in step S301.

[0150] S301. The second communication device sends first information, and correspondingly, the first communication device receives the first information, which is used to configure a first reference signal. The first reference signal is used for sensing and measurement. The first reference signal is a channel state information reference signal (CSI-RS), a tracking reference signal (TRS), or a sounding reference signal (SRS).

[0151] S302. The first communication device receives or transmits a first reference signal based on the first information.

[0152] It should be noted that in step S302, the first communication device may receive the first reference signal based on the first information and determine the sensing measurement result based on the received first reference signal. Alternatively, in step S302, the first communication device may send the first reference signal based on the first information, so that the receiver of the first reference signal determines the sensing measurement result based on the received first reference signal.

[0153] Optionally, the reference signal may have a known amplitude and / or phase. The reference signal may be referred to as a pilot, pilot signal, or reference signal, etc.

[0154] Optionally, the first reference signal is used for sensing measurement, which can be understood as at least one of the following: the first reference signal has the function of sensing measurement; the first reference signal is used to determine the sensing measurement result; the measurement report corresponding to the first reference signal contains the sensing measurement result; or, the function of the first reference signal includes at least sensing.

[0155] For example, the reference signal used for sensing (e.g., a first reference signal) can be used to sense (or reflect) one or more of the following: obstacle information in physical space, transmission channel information formed by collisions with obstacles, or transmission path information. The sensing involved in this application includes, but is not limited to, one or more of the following: positioning, measurement, detection, channel sensing, monitoring, tracking, time measurement, distance measurement, angle measurement, velocity measurement, Doppler frequency shift measurement, point cloud measurement, or sensing feedback.

[0156] Based on the scheme shown in Figure 3, the first information received by the first communication device in step S301 is used to configure a first reference signal, which is used for sensing measurement. Subsequently, in step S302, the first communication device can receive or transmit the first reference signal, enabling the receiver of the first reference signal to obtain the sensing measurement result, thereby enabling the sensing function of the communication device and achieving sensing. Furthermore, the first reference signal used for sensing measurement can be CSI-RS, TRS, or SRS, and these reference signals can be used for other functions. For example, CSI-RS can be used for one or more of channel measurement, beam management, or mobility management; TRS is used for time-frequency offset measurement; and SRS is used for uplink channel measurement and / or uplink beam management. Therefore, in the above scheme, the communication device can use a first reference signal with other functions for sensing measurement, achieving sensing measurement without increasing the type of reference signal, while also saving resource overhead and improving sensing performance.

[0157] In one possible implementation, the first information received by the first communication device in step S301 includes the following first indication information and / or second indication information.

[0158] ① First indication information, indicating that the sensing measurement result of the first reference signal includes Doppler information and / or time delay information.

[0159] Optionally, the first indication information may also indicate that the sensing measurement result of the first reference signal includes at least one of the following: precoding information (e.g., precoding matrix indicator (PMI)), channel rank information (e.g., rank indicator (RI)), and synchronization signal block resource information (e.g., synchronization signal / physical broadcast channel block resource indicator (SSBRI)).

[0160] When the first information includes the first indication information, the first communication device can determine, through the first indication information, that the sensing measurement result of the first reference signal contains Doppler information and / or time delay information, and subsequently, sensing can be achieved through the Doppler information and / or time delay information.

[0161] For example, taking CSI-RS as the first reference signal, the configuration information of CSI-RS may include configuration information for measurement-related quantities, used to indicate the measurement quantities included in the reported measurement results corresponding to CSI-RS. Traditionally, the measurement quantities indicated by this configuration information include one or more of the following: rank indicator (RI), precoding matrix indicator (PMI), channel quality indicator (CQI), or reference signal received power (RSRP). In the above process, the first indication information may indicate that the measurement quantities included in the measurement results corresponding to CSI-RS may include Doppler information and / or time delay information, which can be used for subsequent sensing.

[0162] ② Second indication information, indicating the resource pattern information of the first reference signal.

[0163] When the first information includes the second indication information, the first communication device can determine the resource pattern information of the first reference signal through the second indication information, and can realize flexible configuration of the resource pattern information of the first reference signal.

[0164] For example, the resource pattern information indicates the starting position of the subcarrier occupied by the first reference signal, and / or, the resource pattern information indicates that the number of consecutive resource units occupied by the first reference signal within a resource block includes 6 or 12. In this way, resource pattern information adapted to the characteristics of sensing services (e.g., the continuity of long-term sensing services) can be provided to improve sensing performance.

[0165] For example, taking CSI-RS as the first reference signal, the configuration information of CSI-RS can include configuration information of resource patterns to indicate the resource patterns of CSI-RS. Generally, the CSI-RS pattern includes one or more sub-patterns. For example, a sub-pattern can be represented by (X,Y), where X represents the number of consecutive REs in the frequency domain of the CSI-RS pilot within a single RB, and Y represents the number of consecutive REs in the time domain of the CSI-RS pilot within a single RB. In traditional communication scenarios, the values ​​of (X,Y) include (2,1), (2,2), or (4,1). In the above scheme, the second indication information can indicate that the values ​​of (X,Y) include (6,1) and (12,1), which can provide resource pattern information adapted to the characteristics of sensing services (e.g., long-term sensing services have continuity) to improve sensing performance.

[0166] Optionally, for X=2, the starting RE index can be constrained to be an even number through configuration or pre-configuration.

[0167] Optionally, when X=4, the starting RE index can be constrained to 0,4,8 through configuration or pre-configuration.

[0168] Optionally, for X=6, the starting RE index can be constrained to 0 or 6 through configuration or pre-configuration.

[0169] Optionally, for X=12, the starting RE index can be constrained to 0 through configuration or pre-configuration.

[0170] Optionally, the aforementioned resource block can be a resource block (RB) or another name defined by the network in the future.

[0171] In one possible implementation, the method shown in Figure 3 further includes:

[0172] S303. The first communication device sends second information, and correspondingly, the second communication device receives the second information. The second information includes the sensing measurement result of the first reference signal.

[0173] Therefore, after receiving the first reference signal based on the first information, the first communication device can also send the second information, so that the receiver of the second information can obtain the sensing measurement result of the first reference signal, so as to realize multi-node collaborative sensing (e.g., bi-static sensing).

[0174] Optionally, the first communication device can determine the sensing measurement result based on the received first reference signal to achieve sensing. For example, the first reference signal can be a reference signal sent by another communication device to achieve bi-static sensing with one transmitter and one receiver. Alternatively, the first reference signal can be a reference signal sent by the first communication device to achieve mono-static sensing with self-transmission and self-reception.

[0175] Optionally, the second information may further include third indication information, which indicates that the second information contains the sensing measurement result. Thus, the second information sent by the first communication device may also include the third indication information, enabling the recipient of the second information to determine that the second information contains the sensing measurement result and obtain the sensing measurement result from the second information to achieve sensing.

[0176] In one possible implementation, the first reference signal may be used for one or more of the following, in addition to sensing measurements: channel measurements, beam management measurements, mobility measurements, time-frequency tracking measurements, or positioning measurements. Examples will be described below.

[0177] As an example, taking CSI-RS as the first reference signal, CSI-RS can be used not only for sensing measurements, but also for at least one of channel measurements, beam management measurements, and mobility measurements.

[0178] Optionally, the first information can configure the same CSI-RS in the same frequency layer (FL) to correspond to the four measurement functions mentioned above, including channel measurement, beam management, mobility management, and sensing. Alternatively, the first information can configure different CSI-RS in the same frequency layer for the four measurement functions mentioned above. Or, the first information can configure some CSI-RS in the same frequency layer for some functions, while other CSI-RS are used for other functions.

[0179] Alternatively, FL can be replaced with other descriptions, such as frequency range, frequency domain resources, component carrier (CC), bandwidth part (BWP), or other names defined by the network in the future.

[0180] The following description will be based on the example in Table 3.

[0181] Table 3

[0182] In the example shown in Table 3, CSI-RS1 transmitted in FL1 can be used for some or all of the four measurements mentioned above; the four reference signals transmitted in FL2 (i.e., CSI-RS2, CSI-RS3, CSI-RS4 and CSI-RS5) are used for the four measurements mentioned above, respectively.

[0183] As another example, taking TRS as the first reference signal, TRS can be used not only for sensing measurements but also for time-frequency tracking measurements.

[0184] Optionally, the first information can configure the same TRS within the same FL to correspond to the two measurement functions mentioned above, including sensing and time-frequency tracking. Alternatively, the first information can configure different TRSs within the same frequency layer, each used for one of the two measurement functions. Or, the first information can configure a subset of TRSs within the same frequency layer for some functions, while another subset of TRSs is used for other functions.

[0185] The following description will be based on the example in Table 4.

[0186] Table 4

[0187] In the example shown in Table 4, TRS1 transmitted in FL1 can be used for the two measurements mentioned above; the two reference signals (i.e., TRS2 and TRS3) transmitted in FL2 are used for the two measurements mentioned above, respectively.

[0188] As another example, taking the SRS as the first reference signal, the SRS can be used not only for sensing measurements, but also for uplink channel measurements and / or beam management.

[0189] Optionally, the first information can configure the same SRS of the same FL to correspond to the three measurement functions mentioned above, including sensing, uplink channel measurement, and beam management. Alternatively, the first information can configure different SRSs of the same frequency layer for the three measurement functions mentioned above. Or, the first information can configure a portion of the SRSs of the same frequency layer for some functions, while another portion of the TRSs is used for other functions.

[0190] The following description will be based on the example in Table 5.

[0191] Table 5

[0192] In the example shown in Table 5, SRS1 transmitted in FL1 can be used for the three measurements mentioned above; the three reference signals transmitted in FL2 (i.e., SRS2, SRS3 and SRS4) are used for the three measurements mentioned above, respectively.

[0193] Optionally, in any of the implementation processes in Tables 2 to 6 below, FL1 and FL2 may partially overlap in the frequency domain or may not overlap at all (i.e., FL1 and FL2 are offset in the frequency domain), which is not limited here.

[0194] Optionally, in any of the implementations in Tables 2 to 6 below, the transmission parameters of different reference signals in FL2 may be the same or different in the frequency domain. These transmission parameters include, but are not limited to, one or more of the following: cycle prefix (CP), frequency domain related parameters (e.g., one or more of subcarrier position, start frequency domain position, end frequency domain position, frequency domain bandwidth (BW), and subcarrier spacing (SCS), and time domain related parameters (e.g., one or more of the number of symbols, symbol position, number of time slots, time domain position, number of subframes, subframe position, frame position, and number of frames).

[0195] In one possible implementation, the first communication device can also perform one or more measurements other than sensing measurements based on the above process. Correspondingly, the first communication device can also send the measurement results of the one or more measurements. The following will provide an exemplary description of some possible implementations.

[0196] In the first implementation method, the second information sent by the first communication device in step S303 further includes at least one of the following: channel measurement results, beam management measurement results, mobility measurement results, time-frequency tracking measurement results, or positioning measurement results of the first reference signal.

[0197] In the first implementation, the first reference signal, besides being used for sensing and measurement, can also be used for other functions. Correspondingly, the second information can also include measurement results corresponding to other functions, allowing the same reference signal to be reused for multiple functions and improving resource utilization. Furthermore, the second information can carry other measurement results besides the sensing and measurement results, increasing the amount of information carried by the second information. This allows the receiver of the second information to obtain both the sensing and measurement results and the other measurement results in a single transmission, further improving resource utilization.

[0198] As shown in the example in Figure 4a, the second information may include the sensing measurement results and other possible measurement results (the other measurement results may include at least one of the following: channel measurement results of the first reference signal, beam management measurement results, mobility measurement results, time-frequency tracking measurement results, or positioning measurement results).

[0199] In one possible implementation of the first method, the first information received by the first communication device in step S301 further includes fourth indication information. This fourth indication information indicates that at least one of the following—channel measurement results, beam management measurement results, mobility measurement results, time-frequency tracking measurement results, or positioning measurement results—of the first reference signal is transmitted via the same message / information / signaling as the sensing measurement results of the first reference signal. Therefore, the first information may also include the fourth indication information, enabling the first communication device to transmit different measurement results via the same message / information / signaling (e.g., second information) based on the indication of the fourth indication information, thereby improving resource utilization.

[0200] Optionally, the fourth instruction information may be included in other messages / information / signaling that are different from the first information.

[0201] The second implementation method, as shown in Figure 3, further includes: the first communication device sending third information, which includes at least one of the following: channel measurement results, beam management measurement results, mobility measurement results, time-frequency tracking measurement results, or positioning measurement results of the first reference signal.

[0202] In implementation method two, the first reference signal, besides being used for sensing and measurement, can also be used for other functions. Correspondingly, the third information sent by the first communication device can also include measurement results corresponding to other functions, thus reusing the same reference signal to achieve multiple functions and improve resource utilization. Furthermore, the second information can carry sensing and measurement results, while the third information can carry other measurement results besides those sensing and measurement results. This allows for the transmission of sensing and measurement results as well as communication-related measurement results through different information, enabling the transmission of measurement results for different service types and improving the flexibility of the solution implementation (for example, the recipients of the second and third information may not be the same communication device). Moreover, transmitting sensing and measurement results as well as communication-related measurement results through different information allows different measurement results to be transmitted using multiple smaller resources, reducing the limitation on the transmission resources for measurement results and avoiding or minimizing situations where measurement results cannot be successfully transmitted due to limitations in transmission resource size.

[0203] As shown in the example in Figure 4b, the second information may include the sensing measurement results, and the third information may include other possible measurement results (the other measurement results may include at least one of the following: channel measurement results of the first reference signal, beam management measurement results, mobility measurement results, time-frequency tracking measurement results, or positioning measurement results).

[0204] In one possible implementation of the second method, the first information received by the first communication device in step S301 further includes fifth indication information. This fifth indication information indicates that at least one of the following—channel measurement results, beam management measurement results, mobility measurement results, time-frequency tracking measurement results, or positioning measurement results—of the first reference signal is transmitted via different information than the sensing measurement results of the first reference signal. Therefore, the first information may also include the fifth indication information, enabling the first communication device to transmit different measurement results via different messages / information / signaling (e.g., second information and third information) based on the indication of the fifth indication information.

[0205] Optionally, the fifth instruction information may be included in other messages / information / signaling that are different from the first information.

[0206] Optionally, in addition to the above-described implementation methods one and two, the first communication device may also transmit the data in other ways. For example, the first communication device may determine, through configuration or pre-configuration of the second communication device, that the measurement results included in the transmitted second information include at least one of the following: sensing measurement results, channel measurement results, beam management measurement results, mobility measurement results, time-frequency tracking measurement results, or positioning measurement results.

[0207] For example, taking the CSI-RS in Table 3 above as the first reference signal, in this example, the CSI-RS can be used to determine sensing measurement results, channel measurement results, beam management measurement results, and mobility measurement results. The first communication device can receive indication information A and / or indication information B configured by the second communication device (the indication information A and / or indication information B can be included in the first information or in other information / messages / signaling).

[0208] As an example, the indication information A can contain 3 bits, and different values ​​of these 3 bits represent different measurements. For example, 001 represents the channel measurement result, 010 represents the beam management measurement result, 011 represents the mobility measurement result, 100 represents the sensing measurement result, and 000 represents the default case (i.e., all four functions are sent together).

[0209] For example, when the value of indication information A is 001, the second information contains the channel measurement results.

[0210] For example, when the value of indication information A is 010, the second information contains beam management measurement results.

[0211] For example, when the value of indication information A is 011, the second information includes the mobility measurement result.

[0212] For example, when the value of indication information A is 100, the second information includes the perception measurement result.

[0213] For example, when the value of indication information A is 000, the second information includes the above four measurement results.

[0214] As another example, the indication information B can contain 3 bits, where different values ​​of these 3 bits represent different measurement priorities. This is useful when the resource size corresponding to the second information may not be sufficient to support multiple measurement results; therefore, the indication information B can be used to indicate the priority of each measurement. Similarly, the indication information B can contain 2 bits, where different values ​​of these 2 bits represent different measurements. For example, 00 indicates priority transmission of channel measurement results, 10 indicates priority transmission of beam management measurement results, 11 indicates priority transmission of mobility measurement results, and 11 indicates priority transmission of sensing measurement results.

[0215] For example, when the value of indication information A is 00, the second information includes at least the channel measurement results.

[0216] For example, when the value of indication information A is 01, the second information includes at least the beam management measurement results.

[0217] For example, when the value of indication information A is 10, the second information must include at least the mobility measurement result.

[0218] For example, when the value of indication information A is 11, the second information includes at least the perception measurement result.

[0219] In one possible implementation, the reference signal sequence of the first reference signal is associated with the radio frame index occupied by the first reference signal. Thus, the reference signal sequence of the first reference signal can be associated with the radio frame index occupied by the first reference signal, allowing the first reference signal to be transmitted across radio frames. Since sensing services are continuous, i.e., the accumulation of sensing measurement results at different times can improve the performance of sensing measurements, transmitting the first reference signal across radio frames can improve sensing performance.

[0220] Optionally, the reference signal sequence of the first reference signal is obtained based on the initialization sequence, which satisfies:

[0221]

[0222] Among them, c init This indicates the initialization sequence. Indicates the number of symbols contained in a time slot. This indicates the slot number of the k-th frame when the subcarrier spacing is configured as μ. The subscript 's' represents the slot, 'f' represents the frame, 'k' represents the frame index, 'l' represents the index of the orthogonal frequency division multiplexing (OFDM) symbol within the slot, and 'n' represents the subcarrier spacing. ID This represents the cell identifier, and mod represents the remainder.

[0223] Please refer to Figure 5, which is a schematic diagram of an implementation of the communication method provided in this application. The method includes the following steps.

[0224] S501. The second communication device sends fourth information, and correspondingly, the first communication device receives the fourth information. The fourth information is used to configure a second reference signal, which is used for beam management measurement and is a positioning reference signal (PRS).

[0225] S502. The first communication device receives or transmits a second reference signal based on the fourth information.

[0226] Based on the scheme shown in Figure 5, the fourth information received by the first communication device in step S501 is used to configure the second reference signal, which is used for beam management measurement. This second reference signal is a PRS (Pressure Signal Representation System). Subsequently, in step S502, the first communication device can receive or transmit the second reference signal, enabling the receiver of the second reference signal to obtain the beam management measurement result through the PRS. Therefore, in the above scheme, the communication device can use a second reference signal with other functions to perform beam management measurement, achieving beam management measurement without increasing the type of reference signal, while also saving resource overhead.

[0227] Optionally, the second reference signal can also be used for other functions, including but not limited to at least one of positioning measurement, sensing measurement, channel measurement, mobility measurement, or time-frequency tracking measurement. Thus, the communication device can use the second reference signal with more functions for beam management measurement, achieving beam management measurement without increasing the type of reference signal, while also saving resource overhead.

[0228] It should be noted that the first communication device can receive the second reference signal based on the fourth information and determine the beam management measurement result based on the received second reference signal. Alternatively, the first communication device can send the second reference signal based on the fourth information, so that the receiver of the second reference signal can determine the beam management measurement result based on the received second reference signal.

[0229] As another example, PRS can be used not only for beam management measurements, but also for sensing measurements and / or positioning measurements.

[0230] Optionally, the fourth information can configure the same PRS within the same FL to correspond to the three measurement functions mentioned above, including sensing, localization, and beam management. Alternatively, the fourth information can configure different PRSs within the same frequency layer, each used for one of the three measurement functions. Or, the fourth information can configure a subset of PRSs within the same frequency layer for some functions, while another subset is used for other functions.

[0231] The following description will be based on the example in Table 6.

[0232] Table 6

[0233] In the example shown in Table 6, PRS1 transmitted in FL1 can be used for the three measurements mentioned above; the three reference signals transmitted in FL2 (i.e., PRS2, PRS3 and PRS4) are used for the three measurements mentioned above, respectively.

[0234] Optionally, as shown in Figure 5, the above method may further include:

[0235] S503. The first communication device sends fifth information, and correspondingly, the second communication device receives the fifth information. The fifth information includes beam management measurement results. Optionally, the fifth information may further include sixth indication information, which indicates that the fifth information includes beam management measurement results.

[0236] Optionally, the fifth information may further include at least one of the following: positioning measurement results, sensing measurement results, channel measurement results, mobility measurement results, or time-frequency tracking measurement results. That is, the fifth information may carry beam management measurement results and at least one other measurement result, thereby increasing the amount of information carried by the fifth information. This allows the receiver of the fifth information to obtain the beam management measurement results and the other at least one measurement result in a single transmission, improving resource utilization. Optionally, the fourth information may further include seventh indication information, which is used to instruct the beam management measurement results and the other at least one measurement result to be sent through the same message / information / signaling.

[0237] Alternatively, the first communication device may also send a sixth message, which includes at least one of the following: positioning measurement results, sensing measurement results, channel measurement results, mobility measurement results, or time-frequency tracking measurement results. The fifth message may carry beam management measurement results, while the sixth message may carry the other at least one measurement result. This allows beam management measurement results and the other at least one measurement result to be transmitted through different messages, enabling the transmission of different measurement results using multiple smaller resources. This also reduces the limitation on transmission resources for measurement results, thus avoiding or minimizing the possibility of measurement results failing to be transmitted due to limitations in transmission resource size. Optionally, the fourth message may also include an eighth indication message, which instructs the beam management measurement results and the other at least one measurement result to be sent via different messages / information / signaling.

[0238] It should be noted that the specific implementation of the fifth piece of information can be found in the second piece of information and related implementations mentioned above.

[0264] Please refer to Figure 9, which is a schematic diagram of the structure of the communication device 900 involved in the above embodiments provided in the embodiments of this application. Specifically, the communication device 900 can be a communication device as a network device in the above embodiments. The communication device shown in Figure 9 is implemented through a network device (or a component in a network device). The structure of the communication device can refer to the structure shown in Figure 9.

[0265] The communication device 900 includes at least one processor 911 and at least one network interface 914. Optionally, the communication device further includes at least one memory 912, at least one transceiver 913, and one or more antennas 915. The processor 911, memory 912, transceiver 913, and network interface 914 are connected, for example, via a bus. In this embodiment, the connection may include various interfaces, transmission lines, or buses, etc., and this embodiment is not limited thereto. The antenna 915 is connected to the transceiver 913. The network interface 914 enables the communication device to communicate with other communication devices through a communication link. For example, the network interface 914 may include a network interface between the communication device and core network equipment, such as an S1 interface, or a network interface between the communication device and other communication devices (e.g., other network devices or core network equipment), such as an X2 or Xn interface.

[0266] In Figure 6, the transceiver unit 602 can be a communication interface, which can be the network interface 914 in Figure 9. The network interface 914 can include an input interface and an output interface. Alternatively, the network interface 914 can also be a transceiver circuit, which can include an input interface circuit and an output interface circuit.

[0267] The processor 911 is primarily used to process communication protocols and communication data, control the entire communication device, execute software programs, and process data from these programs, for example, to support the actions described in the embodiments of the communication device. The communication device may include a baseband processor and a central processing unit (CPU). The baseband processor is primarily used to process communication protocols and communication data, while the CPU is primarily used to control the entire terminal device, execute software programs, and process data from these programs. The processor 911 in Figure 9 can integrate the functions of both a baseband processor and a CPU. Those skilled in the art will understand that the baseband processor and CPU can also be independent processors interconnected via technologies such as buses. Those skilled in the art will understand that a terminal device may include multiple baseband processors to adapt to different network standards, and multiple CPUs to enhance its processing capabilities. The various components of the terminal device can be connected via various buses. The baseband processor can also be described as a baseband processing circuit or a baseband processing chip. The CPU can also be described as a central processing circuit or a central processing chip. The function of processing communication protocols and communication data can be built into the processor or stored in memory as a software program, which is then executed by the processor to implement the baseband processing function.

[0268] The memory is primarily used to store software programs and data. The memory 912 can exist independently or be connected to the processor 911. Optionally, the memory 912 can be integrated with the processor 911, for example, integrated into a single chip. The memory 912 can store program code that executes the technical solutions of the embodiments of this application, and its execution is controlled by the processor 911. The various types of computer program code being executed can also be considered as drivers for the processor 911.

[0269] Figure 9 shows only one memory and one processor. In actual terminal devices, there may be multiple processors and multiple memories. Memory can also be called storage medium or storage device, etc. Memory can be a storage element on the same chip as the processor, i.e., an on-chip storage element, or it can be a separate storage element; this application does not limit this.

[0270] Transceiver 913 can be used to support the reception or transmission of radio frequency (RF) signals between a communication device and a terminal. Transceiver 913 can be connected to antenna 915. Transceiver 913 includes a transmitter Tx and a receiver Rx. Specifically, one or more antennas 915 can receive RF signals. The receiver Rx of transceiver 913 receives the RF signals from the antennas, converts the RF signals into digital baseband signals or digital intermediate frequency (IF) signals, and provides the digital baseband signals or IF signals to processor 911 so that processor 911 can perform further processing on the digital baseband signals or IF signals, such as demodulation and decoding. Furthermore, the transmitter Tx in transceiver 913 is also used to receive modulated digital baseband signals or IF signals from processor 911, convert the modulated digital baseband signals or IF signals into RF signals, and transmit the RF signals through one or more antennas 915. Specifically, the receiver Rx can selectively perform one or more stages of downmixing and analog-to-digital conversion on the radio frequency signal to obtain a digital baseband signal or a digital intermediate frequency (IF) signal. The order of these downmixing and IF conversion processes is adjustable. The transmitter Tx can selectively perform one or more stages of upmixing and digital-to-analog conversion on the modulated digital baseband signal or digital IF signal to obtain a radio frequency signal. The order of these upmixing and IF conversion processes is also adjustable. The digital baseband signal and the digital IF signal can be collectively referred to as digital signals.

[0271] The transceiver 913 can also be called a transceiver unit, transceiver, transceiver device, etc. Optionally, the device in the transceiver unit that performs the receiving function can be regarded as the receiving unit, and the device in the transceiver unit that performs the transmitting function can be regarded as the transmitting unit. That is, the transceiver unit includes a receiving unit and a transmitting unit. The receiving unit can also be called a receiver, input port, receiving circuit, etc., and the transmitting unit can be called a transmitter, transmitter, or transmitting circuit, etc.

For example, the apparatus embodiments described above are merely illustrative; for instance, the division of units is only a logical functional division, and in actual implementation, there may be other division methods. For example, multiple units or components may be combined or integrated into another system, or some features may be ignored or not executed. Furthermore, the coupling or direct coupling or communication connection shown or discussed may be an indirect coupling or communication connection between apparatuses or units through some interfaces, and may be electrical, mechanical, or other forms.
