Description

[0001] The present application claims priority from the Chinese patent application No. 202411060306.6 filed on August 2, 2024, and entitled "Resource configuration method and resource configuration 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 technology, in particular to a resource configuration method and a resource configuration apparatus. BACKGROUND

[0003] A channel map is defined as a database for storing channel characteristics based on location information, including channel statistical covariance matrix, angle spectrum, time delay spectrum, and path loss. The establishment of the channel map requires a transmitting end to transmit a reference signal, and a receiving end to perform channel measurement based on the reference signal to obtain the channel characteristics. Before transmitting the reference signal, the resources used for transmitting the reference signal usually need to be configured.

[0004] The current resource configuration method is not conducive to the construction of the channel map. Taking a sounding reference signal (SRS) as an example, the SRS needs to be transmitted in at least 4 consecutive resource blocks (RBs), i.e., at least 12 resource elements (REs). Such a configuration method has a large noise and interference for the construction of the channel map. SUMMARY

[0059] In order to facilitate understanding of the technical solutions of the embodiments of the present application, a brief introduction of the related technologies of the present application is first given.

[0060] 1. Digital channel twin technology

[0061] The fifth generation mobile communication system (5th generation mobile networks, 5G) communication system provides extremely high spectrum efficiency, extremely low communication delay, extremely high connection density and extremely low power consumption. 5G communication has higher requirements on system capacity, spectrum efficiency, etc. As the opening technology of everything connected, 5G communication needs to improve the depth of information interaction to meet the needs of future deep wireless communication networks. The evolved 5G (5G Advanced) wireless communication further improves the information interaction capability to meet the deep mobile Internet demand, thereby continuously expanding the depth and breadth of information interaction, and ultimately realizing the true sense of everything connected. On this basis, the future communication system can greatly expand the breadth and depth of communication coverage, and deeply integrate with deep-sea ocean communication, aviation communication and satellite communication on the basis of traditional cellular communication.

[0062] In the development of communication technology, digital twin is an important technology for depicting, simulating, optimizing and visualizing the physical world in the virtual world. FIG. 1 shows a schematic diagram of a digital twin channel provided by an embodiment of the present application, as shown in FIG. 1, the physical world can provide perception data for constructing a virtual world, and the virtual world provides simulation data for guiding system design and algorithm optimization of the physical world.

[0063] Physical channel is the basis of digital twin model. Accurate perception and mastery of physical channel is the prerequisite for establishing digital twin channel. In the physical channel, the environmental electronic map (including terrain, building distribution, river distribution, vegetation distribution, material electromagnetic parameters, etc.) information is a physical entity. The digital twin channel model describes the interaction and coupling relationship of physical entities, thereby analyzing and predicting the changes of wireless propagation channel. The virtual channel is the real, objective and complete mapping of physical information in digital space, and is the carrier of digital twin channel data. The virtual channel includes geometric model, physical model, behavior model and rule model. The geometric model can describe the physical entities involved in the physical channel, such as the three-dimensional model of the geometric parameters (size, position, etc.) of the terrain and the physical objects, realizing good spatio-temporal consistency with the physical entities. The physical model describes the physical properties and characteristics of the physical channel on the basis of the geometric model, and simulates the structure and electromagnetic field in the wireless channel through digital simulation tools, realizing dynamic approximation simulation of the channel. The behavior model describes the changes of physical channel at different granularities caused by external environmental disturbances, such as the evolution of channel model with spatial changes and the changes of channel with time advancement.

[0064] In actual communication, the application of digital twin channel technology can more effectively master the whole life cycle of communication transmission, and more accurately feed back the communication efficiency to the design end, reducing the feedback overhead and delay of end-to-end.

[0065] 2, Channel map assisted communication technology

[0066] With the evolution of communication systems, system bandwidth increases, terminal antennas increase, network load increases, and the contradiction between wireless channel dimension and limited pilot measurement resources becomes increasingly serious, resulting in great challenges for high-precision wireless channel measurement. Accurate measurement of wireless channel is the cornerstone of mobile communication network research, and is crucial for wireless communication network design, analysis and optimization. Traditional wireless channel measurement methods based on pilot symbols cannot meet the needs of future communication network development, and finding new channel measurement methods has become a hot research topic.

[0067] To solve the problem of limited pilot measurement resources in wireless communication systems, channel maps can be used to realize low-pilot-overhead channel measurement. For example, by providing a candidate beam set at a specific location through a channel map, the overhead of beam scanning in actual communication can be reduced; by providing a channel covariance matrix at a specific location through a channel map, prior channel covariance matrix information can be used to assist in reducing the overhead of reference signals (such as SRS).

[0068] 3, Channel map

[0069] The channel map is defined as a database for storing channel characteristics based on location information, including channel statistical covariance matrix, angle spectrum, time delay spectrum, path loss, etc. In the channel map, the physical cell is divided into two-dimensional grid points, and each grid point stores several channel characteristics in the form of a matrix, a vector, or a scalar.

[0070] 4. SRS

[0071] The SRS is mainly used for uplink channel quality estimation, so as to be used for uplink scheduling, uplink timing advance (TA), uplink resource configuration, etc. In the case of TDD uplink-downlink channel reciprocity, the downlink channel quality can be estimated by using channel symmetry.

[0072] The communication system to which the embodiments of the present application are applied will be described below with reference to FIG. 2.

[0073] FIG. 2 shows a communication system 200 provided by the present application, which includes a terminal device 210, an access network device 220, and a core network device 230.

[0074] The network side includes the core network device 230 and the access network device 220. The core network device 230 can be connected to the access network device 220 in a wireless or wired manner. The terminal device 210 is within the coverage of the access network device 220, and can be connected to the access network device 220 in a wireless manner.

[0075] The access network device 220 and the terminal device 210 can communicate through a wireless link. The access network device 220 or the terminal device 210 can be configured with multiple antennas, which can include at least one transmitting antenna for transmitting signals and at least one receiving antenna for receiving signals. In addition, the access network device 220 or the terminal device 210 additionally includes a transmitter chain and a receiver chain, and those skilled in the art can understand that they can include a plurality of components (such as a processor, a modulator, a multiplexer, a demodulator, a demultiplexer, or an antenna, etc.) related to signal transmission and reception. Therefore, the access network device 220 and the terminal device 210 can communicate through multi-antenna technology.

[0076] It should be understood that FIG. 2 is only a schematic diagram, and the communication system 200 can further include other network devices, such as a wireless relay device and a wireless backhaul device, which are not shown in FIG. 2. The embodiments of the present application do not limit the number of core network devices, access network devices, and terminal devices included in the communication system 200.

[0077] The access network device and the core network device in the embodiments of the present application can be collectively referred to as network devices.

[0079] The access network device can be any kind of device with wireless transceiving function. The access network device includes but is not limited to: an evolved Node B (eNB), a radio network controller (RNC), a Node B (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (for example, a home evolved NodeB or a home Node B, HNB), a baseband unit (BBU), an access point (AP) in a wireless fidelity (WiFi) system, a wireless relay node, a wireless backhaul node, a transmission point (TP) or a transmission reception point (TRP), etc., and can also be a 5G base station (gNB) or a transmission point (TRP or TP) in a 5G (for example, NR) system, one or a group of (including multiple antenna panels) antenna panels of a base station in a 5G system, or a network node constituting a gNB or a transmission point, such as a baseband unit (BBU) or a distributed unit (DU), etc.

[0080] In some deployments, a gNB can include a central unit (CU) and a DU. The gNB can also include an active antenna unit (AAU). The CU implements part of the functionality of the gNB and the DU implements part of the functionality of the gNB. For example, the CU can be responsible for processing non-real time protocols and services, e.g., it can implement functions of the radio resource control (RRC) layer, the service data adaptation protocol (SDAP) layer, and / or the packet data convergence protocol (PDCP) layer. The DU can be responsible for processing real-time services, e.g., it can implement functions of the radio link control (RLC) layer, the medium access control (MAC) layer, and the physical (PHY) layer. One DU can be connected to only one CU or connected to multiple CUs, and one CU can be connected to multiple DUs, the CU and the DU can communicate through an Fl interface. The AAU can implement part of the PHY layer processing functions, radio frequency processing, and related functions of the active antenna. Since the information of the RRC layer is ultimately delivered to the PHY layer and becomes the information of the PHY layer, or is converted from the information of the PHY layer, in this architecture, high layer signaling, such as RRC layer signaling, can also be considered as being transmitted by the DU, or by the DU+AAU.

[0081] It can be understood that the access network device can be a device including one or more of the CU node, the DU node, and the AAU node.

The cell can belong to a macro base station (for example, a macro eNB or a macro gNB, etc.), or a base station corresponding to a small cell. The small cell can include a metro cell, a micro cell, a pico cell, a femto cell, etc., which have characteristics such as small coverage and low transmit power, and are suitable for providing high-speed data transmission services.

[0099] FIG. 4 shows a schematic diagram of an open RAN (O-RAN) system according to an embodiment of the present application. As shown in FIG. 4, an access network device (which can be an eNB or a base station or a next-generation access network device) can communicate with a core network device through a backhaul and communicate with a UE through an air interface.

[0100] Specifically, the BBU in the access network device communicates with the core network through a backhaul, and the radio unit (RU) in the access network device communicates with at least one UE through an air interface. The BBU communicates with at least one RU through a fronthaul, and the BBU and the RU can be co-located or not.

[0101] The BBU includes at least one CU and at least one DU, which can communicate through at least one midhaul. In addition, the access network device further includes a service unit (SU), and the CU and the SU are connected for communication.

[0102] In some examples, the CU is a logical node that carries the radio resource control layer, the service data adaptation protocol (SDAP) layer, the PDCP layer, and other control functions of the access network device. The CU is connected to network nodes such as core networks through some interfaces, which can be E2 interfaces or the like. Optionally, the CU can have part of the functions of the core network. The CU (e.g., the PDCP layer and higher layers) is connected to the DU (e.g., the RLC layer and lower layers) through some interfaces, which can be F1 interfaces or the like. In some examples, these interfaces (e.g., F1 interfaces) can provide control plane (C-Plane) and user plane (U-Plane) functions (e.g., interface management, system information management, UE context management, RRC message transmission, etc.). F1AP is an application protocol of the F1 interface, which defines the signaling procedures of F1 in some examples. The F1 interface supports the control plane F1-C and the user plane F1-U.

[0103] In some examples, the CU can be split into a CU-CP and a CU-UP, where the CU-CP is a logical node that carries the RRC layer and the PDCP-C (control plane part of PDCP) layer, and is used to implement the control plane functions of the CU. The CU-CP can interact with network elements in the core network that are used to implement control plane functions. The network element in the core network that is used to implement control plane functions can be an access and mobility function network element, such as an AMF in a 5G system. The AMF network element is used to be responsible for mobility management in the mobile network, such as location updating of the UE, registration of the UE to the network, handover of the UE, etc. The CU-UP is a logical node that carries the SDAP layer and the PDCP-U (user plane part of PDCP) layer, and is used to implement the user plane functions of the CU. The CU-UP can interact with network elements in the core network that are used to implement user plane functions. The network element in the core network that is used to implement user plane functions, such as a UPF (user plane function) in a 5G system, is used to be responsible for forwarding and receiving data in the UE. The above configurations of the CU and the DU are merely examples, and the CU and the DU can be configured to have functions as needed. For example, the CU or the DU can be configured to have more protocol layer functions, or the CU or the DU can be configured to have partial processing functions of the protocol layers. For example, part of the functions of the RLC layer and the functions of the protocol layers above the RLC layer are arranged in the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are arranged in the DU. For another example, the functions of the CU or the DU can be divided according to the service type or other system requirements, for example, functions that need to meet a relatively short delay requirement in processing time are arranged in the DU, and functions that do not need to meet the delay requirement are arranged in the CU.

[0104] In some examples, a DU is a logical node that hosts RLC layer, MAC layer, Higher PHY layer and other functions. In some examples, a DU can control at least one RU. A DU is connected with an RU through some interfaces, which can be a fronthaul interface. In some examples, the Higher PHY layer includes parts of PHY layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.

[0105] In some examples, an RU is a logical node that hosts Lower PHY layer and radio frequency (RF) processing. In some examples, an RU can be a 3GPP TRP or a remote radio head (RRH) or other similar functional entity. In some examples, the Low-PHY includes parts of PHY processing, such as fast Fourier transform (FFT), inverse fast Fourier transformation (IFFT), digital beamforming and filtering, etc. An RU communicates with one or more UEs through wireless links.

[0106] A DU and an RU can be co-located or not co-located. A DU and an RU exchange control plane information and user plane information via lower-layer split CUS-Plane (LLS-CUS) interface through a fronthaul link. The LLS-CUS can include LLS-C interface and LLS-U interface that provide control plane (C-Plane) and user plane (U-Plane), respectively. In some examples, the control plane (C-Plane) refers to real-time control between the DU and the RU. A DU and an RU exchange management information via LLS-M interface of the fronthaul link, and the management plane (M-Plane) refers to non-real-time management operation between the DU and the RU.

[0107] The DU and RU can cooperate to jointly implement the functions of the PHY layer. One DU can be connected to one or more RUs. The functions of the DU and RU can be configured in multiple ways according to design. For example, the DU is configured to implement baseband functions, and the RU is configured to implement radio frequency functions. For another example, the DU is configured to implement high-layer functions in the PHY layer, and the RU is configured to implement low-layer functions in the PHY layer or to implement the low-layer functions and radio frequency functions. The high-layer functions in the PHY layer can include a part of the functions of the PHY layer that are closer to the MAC layer, and the low-layer functions in the PHY layer can include another part of the functions of the PHY layer that are closer to the radio frequency side.

[0108] In some examples, the CU is a platform for implementing upper-layer (including L2 and L3) functions. The Midhaul and Backhaul interfaces are used to carry traffic between the CU and the DU and between the CU and the core network. The DU implements L1 and part of L2 functions, and the RU implements L1 computation and RF digital part functions. The Fronthaul and Backhaul interfaces are used to carry traffic between the RU and the DU and between the CU and the DU. The integrated DU includes the DU and RU functions described above.

[0109] The CU / DU hardware includes a chassis platform, a mainboard, peripherals, and cooling equipment. The mainboard contains processing units, memories, internal I / O interfaces, and external connection ports. The hardware accelerator design has interfaces, and the hardware function components include storage of software, hardware, and system debugging interfaces, a single-board management controller.

[0110] The DU system is usually implemented using a multi-core processor and one or more hardware accelerators. Part of the DU protocol stack can be implemented in software running on the multi-core processor, and the computation-intensive L1 and L2 functions can be offloaded to hardware accelerators based on field-programmable gate arrays (FPGAs) / graphics processing units (GPUs); or all L1 functions are offloaded to hardware accelerators based on FPGAs / GPUs, and other protocol stack contents are implemented in software running on the processor; or all the protocol stack is implemented in software running on the processor. The hardware accelerator supports interconnection with an x86 or non-x86 processor, and the accelerator has a multi-channel peripheral component interconnect express (PCIe) interface pointing to the CPU and is externally connected through a gigabit Ethernet (GbE) connection.

[0111] The RU includes three parts: an OPU (O-RAN processing unit) receives eCPRI frames from the O-RAN fronthaul and performs the fronthaul interface, the bottommost L1 (encoding, scrambling, modulation, layer mapping, precoding), synchronization, beamforming, and resource unit mapping. The OPU can be implemented as a CPU, FPGA, or ASIC. A DPU (digital processing unit of the O-RU) performs synchronization, DDC (digital down conversion in the UL), DUC (digital up conversion in the DL), CFR, and DPD to improve power amplifier efficiency by reducing the PAPR / ACLR of the RF front end; the DPU can be implemented as an FPGA or ASIC. The RF processing unit of the O-RU includes a transceiver module, an up / down converter, a power amplifier (PA), a low-noise amplifier (LNA), a Tx / Rx filter. All conversions between the analog and digital domains (DAC and ADC) (for example, (RF sampling, using RF, IF, and LO mixing for frequency conversion in upconversion and downconversion) are performed within the transceiver module. Note that the physical and logical partitions within the RF processing unit do not require specific boundaries.

[0112] It should be noted that the names of messages between various network elements in the embodiments of the present application or the names of various parameters in the messages are only examples, and other names can also be used in specific implementations, and the embodiments of the present application do not limit the names.

[0113] It can be understood that in the embodiments of the present application, the access network device and / or the terminal device can perform part or all of the steps in the embodiments of the present application, and these steps or operations are only examples, and the embodiments of the present application can also perform other operations or variations of various operations. In addition, various steps can be executed in different orders according to the embodiments of the present application, and it is possible that not all operations in the embodiments of the present application are executed.

[0114] At present, the resources of the SRS are often transmitted on multiple REs, such as full-band or sub-band transmission, which can cause the SRS to be significantly affected by interference and noise when the channel map is constructed, and further, cause the construction accuracy of the channel map to be poor.

[0115] Based on this, the present application provides a resource configuration method and a resource configuration device, which can configure fewer resource units for transmitting reference signals, can converge power on fewer resource units, and is beneficial to improving the signal-to-interference-and-noise ratio of channel measurement and the construction accuracy of the channel map. It should be understood that the resource configuration method of the embodiments of the present application can be applied to the map construction scenario. Of course, the method can also be applied to other scenarios. The present application does not specifically limit the applicable scenarios of the method, and the above exemplary scenarios do not constitute any limitation on the method.

It should be understood that the technical solutions of the present application can be applied to a wireless communication system, for example, the communication system 200 shown in FIG. 2. Two communication apparatuses in the wireless communication system can have a wireless communication connection relationship, and one of the two communication apparatuses can correspond to the terminal device 210 shown in FIG. 2, or can be a chip configured in the terminal device 210; the other of the two communication apparatuses can correspond to the access network device 220 shown in FIG. 2, or can be a chip configured in the access network device 220.

[0117] In the following, the resource configuration method provided in the embodiments of the present application will be described in detail with the interaction process between the terminal device and the access network device as an example without loss of generality.

[0118] The technical solutions provided in the embodiments of the present application can be applied to wireless communication between communication devices. The wireless communication between communication devices can include wireless communication between a network device and a terminal device, wireless communication between network devices, and wireless communication between terminal devices. In the embodiments of the present application, the term “wireless communication” can also be referred to as “communication”, and the term “communication” can also be described as “data transmission”, “information transmission” or “transmission”.

[0119] In the present application, “sending information to a terminal device” can be understood as that the destination of the information is the terminal device, which can include directly or indirectly sending information to the terminal device. “Receiving information from a terminal device” can be understood as that the source of the information is the terminal device, which can include directly or indirectly receiving information from the terminal device. The information can be processed as necessary between the source and the destination of the information, but the destination can understand the valid information from the source. Similar expressions in the present application can be understood similarly, and will not be described here.

[0120] FIG. 5 shows a flow diagram of a resource configuration method provided in an embodiment of the present application. The method 500 can be applied to the communication system 200 shown in FIG. 2, can be applied to the communication system 300 shown in FIG. 3, can be applied to the O-RAN system shown in FIG. 4, and can be applied to other communication systems, which are not limited in the embodiments of the present application. The resource configuration method 500 includes the following steps:

[0121] S501, the terminal device sends first information to the access network device, and correspondingly, the access network device receives the first information from the terminal device, wherein the first information is used to indicate a first quantity, and the first quantity is the minimum number of resource units supported by the terminal device for simultaneous uplink transmission.

[0122] The first information can be understood as the capability of the terminal device with respect to the channel map.

[0123] In a possible implementation, the terminal device can actively send the first information to the access network device.

[0124] In another possible implementation, the terminal device can send the first information to the access network device based on a query request of the access network device.

[0125] S502, the access network device sends a downlink reference signal to the terminal device, and correspondingly, the terminal device receives the downlink reference signal and performs channel measurement by using the downlink reference signal.

[0126] S503, the terminal device sends second information to the access network device, and correspondingly, the access network device receives the second information from the terminal device, and the second information is used to indicate the positions of a second number of resource units whose received power of the downlink reference signal satisfies a preset condition.

[0127] Optionally, for multiple physical antennas of the terminal device, in order to obtain diversity gain, the correlation between the multiple physical antennas is relatively low, so the positions of the strongest power resource units on different physical antennas are often different. In the embodiment of the present application, the positions of the second number of resource units can include: the positions of a fourth number of resource units whose received power of the downlink reference signal satisfies the preset condition on each physical antenna of the terminal device, and the fourth number is less than the second number. In other words, the terminal device can determine the positions of the fourth number of resource units with the strongest power for each physical antenna separately.

[0128] Optionally, the number of the positions of the resource units reported by each physical antenna is not limited in the embodiment of the present application, and the number of the positions of the resource units reported by each physical antenna can be equal or not equal.

[0129] S504, the access network device sends third information to the terminal device based on the first information and the second information, and correspondingly, the terminal device receives the third information. The third information is used to indicate a third number and the positions of the third number of resource units, and the third number of resource units are used for map construction, and the third number is greater than or equal to the first number.

[0130] In the embodiments of the present application, the access network device can determine the positions of the third number of resource units from the positions of the second number of resource units with the strongest received power. The positions of the third number of resource units can all be from the positions of the second number of resource units, or can be partially from the positions of the second number of resource units, which is not limited in the embodiments of the present application.

[0131] For example, the first number is X1, the second number is X2, and the third number is X3. X3 is greater than or equal to X1, which can ensure that the number of resource units used by the terminal device to support simultaneous uplink transmission is sufficient for graph construction. X2 can be greater than or equal to X1 to further improve the accuracy of graph construction. X3 can be greater than or equal to X2, which is not limited in the embodiments of the present application, and can be adjusted according to actual application scenarios.

[0132] For example, the third number can be less than 12, and the specific value of the third number is not limited in the embodiments of the present application, and can be set according to actual application scenarios.

[0133] Optionally, the third information is further used to indicate the transmission power of the uplink reference signal on the third number of resource units, and the transmission power is greater than or equal to a preset power. The positions of the resource units can include a bitmap of configurable resource units or a starting position and an offset position of the resource units.

[0134] The preset power can be full power or other power values, which is not limited in the embodiments of the present application, and can be set according to actual application scenarios.

[0135] Optionally, the third information is further used to indicate a plurality of resources, the plurality of resources include the third number of resource units, and each resource in the plurality of resources includes at least one resource unit in the third number of resource units. The third information is further used to indicate that the terminal device sends the uplink reference signal by the plurality of physical antennas in turn.

[0136] For each physical antenna of the terminal device, the ID of each resource corresponds to the ID of the physical antenna of the terminal device, and the positions of the resource units can include a bitmap of configurable resource units or a starting position and an offset position of the resource units.

[0137] In summary, the terminal device sends first information to the access network device, the first information being used to indicate a minimum number of resource units used by the terminal device for supporting uplink simultaneous transmission, and the terminal device sends second information to the access network device, the second information being used to indicate positions of the second number of resource units of a downlink reference signal, so that the access network device can refer to the first information and the second information when configuring resources of the reference signal for the terminal device, and the reference signal can be transmitted at the positions of the fewer resource units, the signal-to-interference ratio of channel measurement can be improved, and thus the construction accuracy of a channel map can be improved.

[0138] FIG. 6 shows a flowchart of another resource configuration method provided by an embodiment of the present application. The method 600 can be applied to the communication system 200 shown in FIG. 2, the communication system 300 shown in FIG. 3, the O-RAN system shown in FIG. 4, or other communication systems, which are not limited in the embodiments of the present application. As shown in FIG. 6, the resource configuration method 600 includes the following steps:

[0139] S601, the access network device sends fourth information to the terminal device, and correspondingly, the terminal device receives the fourth information sent by the access network device, the fourth information being used to request querying the first number.

[0140] The access network device can send the first information to the terminal device through a terminal device capability inquiry message, to inquire the capability of the terminal device on the channel map, that is, to request querying the first number, the first number being a minimum number of resource units used by the terminal device for supporting uplink simultaneous transmission, the resource unit being, for example, an RE.

[0144] The preset condition can be a position of a second number of resource units corresponding to a relatively strongest received power of the downlink reference signal arranged in descending order of received power, or a position of a second number of resource units determined from resource units with a received power greater than a received power threshold.

[0145] Optionally, the access network device can configure the terminal device to report a position of a fourth number of resource units with the strongest received power on each physical antenna of the terminal device, and the fourth number is less than the second number.

The third information is used to indicate a third number and a position of the third number of resource units, and the third number of resource units is used for graph construction, and the third number is greater than or equal to the first number.

[0148] S607, the terminal device sends an uplink reference signal at the third number and the position of the third number of resource units indicated by the third information.

[0149] S608, the access network device receives the uplink reference signal and performs channel estimation.

[0150] Specifically, the access network device can obtain a channel state of a corresponding resource unit and calculate a spatial domain channel. The uplink reference signal can be an SRS.

[0151] The embodiment of the present application can send a reference signal at a position of a smaller number of resource units, which can improve a signal-to-interference ratio of channel measurement, thereby improving a construction accuracy of a channel graph.

[0152] As an optional embodiment, the access network device can also send sixth information to other network devices or a graph management function network element (MMF), and the sixth information is used to indicate the position of the third number of resource units. If the access network device sends the above-mentioned sixth information to the MMF, the MMF can forward the sixth information to other network devices. In this way, other network devices can avoid the above-mentioned position and use different positions of resource units to transmit a reference signal as much as possible, thereby avoiding interference.

[0153] The above-mentioned other network devices can be adjacent access network devices of the access network device.

[0154] FIG. 7 shows another resource configuration method provided by the embodiments of the present application. As shown in FIG. 7, the method includes the following steps:

[0155] S701. The access network device 1 sends sixth information to the MMF, where the sixth information is used to indicate the positions of the third quantity of resource units. Correspondingly, the MMF receives the sixth information.

As shown in FIG. 8, in the frequency domain or the time domain, there are a cell 1, a cell 2 and a cell 3, and through the execution of the above method, the resource units adopted by the three cells for transmitting the reference signal are different.

[0161] In other possible implementation manners, one access network device can correspond to multiple cells, and the access network device can configure different resource units for different cells to avoid interference between the cells.

In FIG. 9, the access network device includes an SU, a CU, an RU and a DU, the DU includes a DU1 and a DU2, and the RU includes an RU1 and an RU2. The DU1 and the RU1 belong to a cell 1, and the DU2 and the RU2 belong to a cell 2. Exemplarily, in the case where the resource units used by the cell 1 have been determined, the CU can allocate another part of resource units for the cell 2, which are different from the resource units used by the cell 1.
