Description

A communication method, apparatus and system

[0001] This application claims priority to Chinese Patent Application No. 202411999053.9, filed with the China National Intellectual Property Administration on December 31, 2024, entitled "A Communication Method, Apparatus and System", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and more specifically, to a communication method, apparatus, and system. Background Technology

[0003] A reference signal (RS), also known as a pilot signal, is sent from the transmitter to the receiver for channel estimation or channel sounding. Uplink reference signals include, but are not limited to, sounding reference signals (SRS).

[0004] For example, SRS usage includes antenna switching, codebook, noncodebook, and beam management. In antenna switching SRS transmission, the network device configures an SRS resource set for the terminal device based on the terminal capabilities reported by the terminal device. The terminal device then sends the SRS according to the configuration parameters of one or more SRS resources included in the SRS resource set. The network device performs channel measurement and estimation based on the received SRS. However, current SRS resource configuration schemes may not be suitable for future terminal architectures. Therefore, designing a new SRS resource configuration scheme is a problem that needs to be considered. Summary of the Invention

[0005] This application provides a communication method, apparatus, and system that enables terminal devices to send SRS based on the SRS resource set configured in network devices, thereby ensuring transmission performance.

[0006] Firstly, a communication method is provided. This method can be executed by the terminal side. Unless otherwise specified, the terminal side in this application can be a terminal device, or a component in the terminal device (e.g., a processor, chip, or chip system, such as a circuit or chip responsible for communication functions in the terminal device side (e.g., a modem chip, also known as a baseband chip, or a system-on-chip (SoC) chip containing a modem core or a system-in-package (SIP) chip), or it can be a logic module or software that can implement all or part of the functions of the terminal device.

[0007] The method includes: receiving first configuration information, the first configuration information being used to indicate a first sounding reference signal (SRS) resource set, the first SRS resource set being used for antenna switching, the first SRS resource set including multiple SRS resources, each of the multiple SRS resources including multiple SRS ports, the multiple SRS resources including a first SRS resource and a second SRS resource, the first SRS port included in the first SRS resource and the second SRS port included in the second SRS resource being associated with the same terminal device port; and sending an SRS according to the first configuration information.

[0008] Based on the above scheme, the terminal device obtains the first SRS resource set by receiving the first configuration information. The first SRS resource set includes the first SRS resource and the second SRS resource. The first SRS port in the first SRS resource and the second SRS port in the second SRS resource can be associated with the same UE port, which enables terminals of different forms to send antenna switching SRS, ensuring that the network device can receive all SRS and complete channel measurement and estimation, while ensuring transmission performance.

[0009] Secondly, a communication method is provided. This method can be executed by the network side. Unless otherwise specified, the network side in this application can be a network device, a component in the network device (such as a modem chip, also known as a baseband chip, or a system-on-a-chip (SoC) chip or system-in-package (SIP) chip containing a modem core), or a logic module or software that can implement all or part of the functions of the network device.

[0010] The method includes: determining first configuration information, the first configuration information being used to indicate a first detection reference signal (SRS) resource set, the first SRS resource set being used for antenna switching, the first SRS resource set including multiple SRS resources, each of the multiple SRS resources including multiple SRS ports, the multiple SRS resources including a first SRS resource and a second SRS resource, the first SRS port included in the first SRS resource and the second SRS port included in the second SRS resource being associated with the same terminal device port; and sending the first configuration information.

[0011] Based on the above scheme, the network device sends first configuration information to indicate the first SRS resource set, wherein the first SRS resource set includes the first SRS resource and the second SRS resource. The first SRS port in the first SRS resource and the second SRS port in the second SRS resource can be associated with the same UE port, which enables different types of terminals to send antenna switching SRS, ensuring that the network device can receive all SRS and complete channel measurement and estimation, while ensuring transmission performance.

[0012] In conjunction with the first or second aspect, in some implementations, the first configuration information can be sent via radio resource control (RRC) signaling.

[0013] In conjunction with the first or second aspect, in some implementations, the first SRS resource also includes a third SRS port, and the second SRS resource also includes a fourth SRS port, with the third SRS port and the fourth SRS port associated with different terminal device ports.

[0014] In other words, the first SRS resource includes the first SRS port and the third SRS port, and the second SRS resource includes the second SRS port and the fourth SRS port. Assuming that the first SRS port and the second SRS port are both SRS port 0, and the third SRS port and the fourth SRS port are both SRS port 1, then the two SRS port 0s are associated with the same UE port, and the two SRS port 1s are associated with different UE ports.

[0015] In conjunction with the first or second aspect, in some implementations, the first SRS port and the third SRS port are associated with different terminal device ports, and the second SRS port and the fourth SRS port are associated with different terminal device ports.

[0016] In other words, for a 2T6R UE, the first SRS resource includes the first SRS port and the third SRS port, and the second SRS resource includes the second SRS port and the fourth SRS port. Assuming that the first SRS port and the second SRS port are both SRS port 0, and the third SRS port and the fourth SRS port are both SRS port 1, then the SRS port 0 and SRS port 1 included in the first SRS resource are associated with different UE ports, and the SRS port 0 and SRS port 1 included in the second SRS resource are associated with different UE ports.

[0017] Understandably, a 2T6R UE can be viewed as an antenna module composed of 1T2R and 1T4R modules. Here, 1T2R indicates that the UE supports 1 antenna port for simultaneous signal transmission and 2 antenna ports for simultaneous signal reception; 1T4R indicates that the UE supports 1 antenna port for simultaneous signal transmission and 4 antenna ports for simultaneous signal reception. Thus, this UE supports 2 antenna ports for simultaneous signal transmission and 6 antenna ports for simultaneous signal reception.

[0018] In conjunction with the first or second aspect, in some implementations, the port number of the first SRS port and the second SRS port is 1000, and the port number of the third SRS port and the fourth SRS port is 1001.

[0019] In conjunction with the first or second aspect, in some implementations, the port number of the first SRS port and the second SRS port is 1001, and the port number of the third SRS port and the fourth SRS port is 1000.

[0020] In conjunction with the first or second aspect, in some implementations, the port number of the first SRS port and the fourth SRS port is 1000, and the port number of the second SRS port and the third SRS port is 1001.

[0021] In conjunction with the first or second aspect, in some implementations, the port number of the first SRS port and the fourth SRS port is 1001, and the port number of the second SRS port and the third SRS port is 1000.

[0022] In conjunction with the first or second aspect, in some implementations, the first SRS resource also includes a third SRS port and a fifth SRS port, and the second SRS resource also includes a fourth SRS port and a sixth SRS port. The third SRS port and the fourth SRS port are associated with the same terminal device port, and the fifth SRS port and the sixth SRS port are associated with different terminal device ports.

[0023] In other words, the first SRS resource includes the first SRS port, the third SRS port, and the fifth SRS port; the second SRS resource includes the second SRS port, the fourth SRS port, and the sixth SRS port. Assuming that the first and second SRS ports are both SRS port 0, the third and fourth SRS ports are both SRS port 1, and the fifth and sixth SRS ports are both SRS port 2, then the two SRS ports 0 are associated with the same UE port, the two SRS ports 1 are associated with the same UE port, and the two SRS ports 2 are associated with different UE ports.

[0024] In conjunction with the first or second aspect, in some implementations, the first SRS port, the third SRS port, and the fifth SRS port are associated with different terminal device ports, and the second SRS port, the fourth SRS port, and the sixth SRS port are associated with different terminal device ports.

[0025] In other words, for a 3T8R UE, the first SRS resource set contains four 3-port SRS resources, such as the first SRS resource, the second SRS resource, the third SRS resource, and the fourth SRS resource. Each SRS resource includes SRS port 0, SRS port 1, and SRS port 2. Specifically, SRS port 0 in the first and third SRS resources can be associated with the same UE port (e.g., the first UE port); SRS port 1 in the first and third SRS resources can be associated with the same UE port (e.g., the second UE port); SRS port 0 in the second and fourth SRS resources can be associated with the same UE port (e.g., the third UE port); and SRS port 1 in the second and third SRS resources can be associated with the same UE port (e.g., the fourth UE port).

[0026] Understandably, a 3T8R UE can be viewed as an antenna module composed of 2T4R and 1T4R modules. Here, 2T4R indicates that the UE supports 2 antenna ports for simultaneous signal transmission and 4 antenna ports for simultaneous signal reception, while 1T4R indicates that the UE supports 1 antenna port for simultaneous signal transmission and 4 antenna ports for simultaneous signal reception. Thus, this UE supports 3 antenna ports for simultaneous signal transmission and 8 antenna ports for simultaneous signal reception.

[0063] It is understandable that the port numbers of the SRS ports mentioned above are just examples for ease of understanding, and other solutions are not excluded.

[0064] Thirdly, a communication method is provided. This method can be executed by the terminal side. Unless otherwise specified, the terminal side in this application can be a terminal device, or a component in the terminal device (e.g., a processor, chip, or chip system, such as a circuit or chip responsible for communication functions in the terminal device side (e.g., a modem chip, also known as a baseband chip, or a SoC chip or SIP chip containing a modem core), or it can be a logic module or software that can implement all or part of the functions of the terminal device.

[0065] The method includes: receiving second configuration information, the second configuration information being used to indicate a first sounding reference signal (SRS) resource set, the first SRS resource set being used for antenna switching, the first SRS resource set including multiple SRS resources, each of the multiple SRS resources including at least one SRS port, the multiple SRS resources including a first SRS resource and a second SRS resource, the transmission power linearity of the second SRS resource being 1 / N of the transmission power linearity of the first SRS resource, where N is an integer greater than 1; and transmitting SRS according to the second configuration information.

[0066] Based on the above scheme, the terminal device can obtain the first SRS resource set by receiving the second configuration information. The first SRS resource set includes the first SRS resource and the second SRS resource. Multiple SRS resources can contain different numbers of SRS ports. The linearity of the transmission power of the second SRS resource is 1 / N of the linearity of the transmission power of the first SRS resource. By introducing a new SRS power allocation mechanism to constrain the transmission power of different SRS resources contained in the first SRS resource set, it can be ensured that the transmission power of different SRS ports is aligned, while avoiding measurement errors. This enables terminals of different forms to send antenna switching SRS, ensuring that the network device can receive all SRS and complete channel measurement and estimation, while ensuring transmission performance.

[0067] Fourthly, a communication method is provided. This method can be executed by the network side. Unless otherwise specified, the network side in this application can be a network device, a component in the network device (such as a modem chip, also known as a baseband chip, or a system-on-a-chip (SoC) chip or system-in-package (SIP) chip containing a modem core), or a logic module or software that can implement all or part of the functions of the network device.

[0068] The method includes: determining second configuration information, the second configuration information being used to indicate a first sounding reference signal (SRS) resource set, the first SRS resource set being used for antenna switching, the first SRS resource set including multiple SRS resources, each of the multiple SRS resources including at least one SRS port, the multiple SRS resources including a first SRS resource and a second SRS resource, the transmission power linearity of the second SRS resource being 1 / N of the transmission power linearity of the first SRS resource, where N is a positive integer; and transmitting the second configuration information.

[0069] Based on the above scheme, the network device instructs the first SRS resource set by sending second configuration information. The first SRS resource set includes first SRS resources and second SRS resources. Multiple SRS resources can contain different numbers of SRS ports. The linearity of the transmission power of the second SRS resource is 1 / N of the linearity of the transmission power of the first SRS resource. By introducing a new SRS power allocation mechanism to constrain the transmission power of different SRS resources contained in the first SRS resource set, it is possible to ensure that the transmission power of different SRS ports is aligned, while avoiding measurement errors. This enables terminals of different forms to send antenna switching SRS, ensuring that the network device can receive all SRS and complete channel measurement and estimation, while ensuring transmission performance.

[0070] In conjunction with the third or fourth aspect, in some implementations, this second configuration information can be sent via RRC signaling.

[0071] In conjunction with the third or fourth aspect, in some implementations, the number of SRS ports contained in the first SRS resource is different from the number of SRS ports contained in the second SRS resource.

[0072] In conjunction with the third or fourth aspect, in some implementations, the first SRS resource includes m1 SRS ports, and the second SRS port includes m2 SRS ports, where... Both m1 and m2 are positive integers.

[0073] It should be noted that the linearity of transmission power of different SRS resources containing different numbers of SRS ports is different, and the relationship between the linearity of transmission power of different SRS resources depends on the number of SRS ports contained in the different SRS resources.

[0074] Based on the above scheme, by configuring different linear values ​​of transmission power for different SRS resources, it can be ensured that the transmission power of different SRS ports is aligned. This avoids measurement errors on the receiving side when measuring the channels corresponding to different SRS ports due to the imbalance of transmission power of different SRS ports, thus ensuring transmission performance.

For example, the communication device includes modules, units or means corresponding to the operations involved in the first aspect above.

[0127] The communication system to which this application applies will now be described with reference to the accompanying drawings.

[0128] The technical solutions of this application can be applied to various communication systems, such as: Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, 5G systems, or New Radio (NR) and future communication systems.

[0129] Furthermore, the embodiments of this application are applicable to both homogeneous and heterogeneous network scenarios, and there are no restrictions on the transmission points. They can be applied to systems such as multi-point collaborative transmission between macro base stations, micro base stations, and macro base stations. The embodiments of this application are applicable to both low-frequency and high-frequency scenarios, including terahertz and optical communications.

[0130] In a communication system, a device can send signals to or receive signals from another device. These signals may include reference signals, information, signaling, or data. In this application, "device" can be replaced by an entity, network entity, communication equipment, communication module, node, or communication node.

[0131] Figure 1 is a schematic diagram of a communication system applicable to an embodiment of this application. As shown in Figure 1, the communication system 10 includes a radio access network (RAN) 100 and a core network (CN) 200. RAN 100 includes at least one RAN node (110a and 110b in Figure 1, collectively referred to as 110) and at least one terminal (120a-120j in Figure 1, collectively referred to as 120). RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 1). Terminal 120 is wirelessly connected to RAN node 110. RAN node 110 is wirelessly or wired connected to core network 200. The core network devices in core network 200 and RAN node 110 in RAN 100 can be different physical devices, or they can be the same physical device integrating core network logical functions and radio access network logical functions.

[0132] RAN 100 can be a cellular system related to the 3rd Generation Partnership Project (3GPP), such as a 4G mobile communication system, a 5G mobile communication system, or a future-oriented evolution system. RAN 100 can also be an open access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (WiFi) system. RAN 100 can also be a communication system that integrates two or more of the above systems.

[0133] RAN node 110, sometimes also referred to as network equipment, access network equipment, RAN entity, or access node, constitutes part of the communication system and is used to help terminals achieve wireless access. Multiple RAN nodes 110 in communication system 10 can be of the same type or different types. In some scenarios, the roles of RAN node 110 and terminal 120 are relative. For example, network element 120i in Figure 1 can be a helicopter or drone, which can be configured as a mobile base station. For terminals 120j accessing RAN 100 through network element 120i, network element 120i is a base station; but for base station 110a, network element 120i is a terminal. RAN node 110 and terminal 120 are sometimes both referred to as communication devices. For example, network elements 110a and 110b in Figure 1 can be understood as communication devices with base station functions, and network elements 120a-120j can be understood as communication devices with terminal functions.

[0134] In one possible scenario, a RAN node can be a base station (BS), an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a base station in a future mobile communication system, or an access node in a WiFi system. A RAN node can be a macro base station (as shown in Figure 1, 110a), a micro base station or indoor station (as shown in Figure 1, 110b), a relay node or donor node, or a radio controller in a CRAN scenario. Optionally, a RAN node can also be a server, wearable device, vehicle, or in-vehicle equipment. For example, the access network equipment in vehicle-to-everything (V2X) technology can be a roadside unit (RSU).

[0135] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, with different RAN nodes each implementing some of the base station's functions. For example, a RAN node can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CU-CP), a CU-user plane (CU-UP), a radio unit (RU), or a CU-radio unit (CU-RU), etc. CUs and DUs can be set up separately or included in the same network element, such as a baseband unit (BBU). RUs can be included in radio equipment or radio units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs).

[0136] In different systems, CU (including open CU-CP (O-CU-CP) and open CU-UP (O-CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called an open centralized unit (O-CU), DU can also be called an open distributed unit (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 and hardware modules.

[0137] Terminal 120 can be a device or module that accesses the aforementioned communication system and has corresponding communication functions. A terminal can also be referred to as user equipment (UE), terminal, user device, access terminal, user unit, user station, mobile station, mobile station (MS), remote station, remote terminal, mobile device, user terminal, terminal unit, terminal station, terminal device, wireless communication equipment, user agent, or user device. A terminal typically contains a communication module, circuit, or chip that performs the corresponding communication functions. The terminal may also be configured with program instructions for performing these communication functions.

[0138] For example, the terminal in this application embodiment can be a mobile phone, a personal digital assistant (PDA) computer, a laptop computer, a tablet computer, a drone, a computer with wireless transceiver capabilities, a machine type communication (MTC) terminal, a virtual reality (VR) terminal, an augmented reality (AR) terminal, an Internet of Things (IoT) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical care, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home (e.g., game consoles, smart TVs, smart speakers, smart refrigerators, and fitness equipment), a transport vehicle with wireless communication capabilities, a communication module, or a roadside unit (RSU) with terminal capabilities.

[0139] RAN 100 and terminal 120 can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the scenarios in which RAN 100 and terminal 120 are located.

[0140] 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.

[0141] The correspondence between network elements and their achievable protocol layer functions in the ORAN system can be found in Table 1 below.

[0142] Table 1

[0143] CN 200 can be a 5G core network or an evolved 5G core network. Taking a 5G core network as an example, CN 200 includes access and mobility management (AMF) network elements responsible for mobility management and access management services; session management (SMF) network elements responsible for session management; user plane (UPF) network elements responsible for user plane packet routing and forwarding and quality of service (QoS) control; and policy control (PCF) network elements. These core network elements can operate independently or be combined to implement certain control functions; for example, AMF, SMF, and PCF can be combined into a single core network device.

[0144] The communication system 10 provided in this application may further include artificial intelligence (AI) network elements to implement some or all AI-related operations. AI network elements may also be referred to as AI nodes, AI devices, AI entities, AI modules, AI models, or AI units, etc. The AI ​​network elements may be built into the network elements of the communication system. For example, an AI network element may be an AI module built into access network equipment, core network equipment, cloud servers, or operation, administration, and maintenance (OAM) management systems to implement AI-related functions. The OAM may be the management system for core network equipment and / or the management system for access network equipment. Alternatively, the AI ​​network element may also be an independently configured network element in the communication system. Optionally, the terminal or its built-in chip may also include an AI entity to implement AI-related functions.

[0145] Figure 2 is a schematic diagram of the Open Radio Access Network (O-RAN) architecture applicable to this application. As shown in Figure 2, the O-RAN architecture includes: a first network unit, a second network unit, a third network unit, an O-eNB, an O-CU-CP, an O-CU-UP, an O-DU, an O-RU, and an O-cloud.

[0146] The aforementioned network elements (also referred to as nodes) can be interconnected. For example, the first network unit connects to the O-cloud via the O2 interface; the first network unit connects to the third network unit, O-eNB, O-CU-CP, O-CU-UP, O-DU, and O-RU via the O1 interface; the first network unit connects to the O-RU via the open fronthaul M-Plane interface; the O-DU connects to the O-RU via the open fronthaul M-Plane interface and the open fronthaul C / U / S-Plane interface; the third network unit connects to the O-eNB, O-CU-CP, O-CU-UP, and O-DU via the E2 interface; the O-CU-CP connects to the O-DU via the F1-c interface; the O-CU-UP connects to the O-DU via the F1-u interface; and the O-CU-CP connects to the O-CU-UP via the E1 interface. For a detailed description of the interfaces shown in Figure 2, please refer to existing standards; further details are omitted here.

[0147] For example, the first network unit can be a service management and orchestration framework (SMO), or a network unit with similar functionality to an SMO; there is no limitation in this regard. The second network unit can be a Non-RT RIC, or a network unit with similar functionality to a Non-RT RIC; there is no limitation in this regard. The third network unit can be a Near-RT RIC, or a network unit with similar functionality to a Near-RT RIC; there is no limitation in this regard.

[0148] O-RAN aims to achieve an intelligent and open access network. A key feature of the O-RAN architecture is the separation of hardware and software, enabling the virtualization of network functions and the standardization of hardware. Furthermore, O-RAN incorporates artificial intelligence (AI).

[0149] It should be understood that the above naming is defined solely for the purpose of distinguishing different functions and should not constitute any limitation on this application. This application does not preclude the possibility of using other naming conventions in 5G networks and other future networks. For example, in future networks, some or all of the above-mentioned network elements may use the terminology from 5G, or they may use other names, etc.

[0150] It is understood that Figure 1 or Figure 2 are provided as examples for ease of understanding and do not constitute a limitation on the scope of protection of this application. The communication method provided in the embodiments of this application may also involve network elements not shown in Figure 1 or Figure 2, and of course, the communication method provided in the embodiments of this application may also include only some of the network elements shown in Figure 1 or Figure 2.

[0151] To facilitate understanding of the embodiments of this application, the basic concepts involved in this application will be explained first.

[0152] 1. Reference signals: The reference signals involved in this application include, but are not limited to:

[0153] Pilot reference signals (e.g., channel state information-reference signal (CSI-RS) and / or sounding reference signal (SRS)), demodulation reference signals (DMRS), tracking reference signals (TRS), phase tracking reference signals (PT-RS), positioning reference signals (PRS), or sensing reference signals (SeRS), etc. Optionally, the pilot reference signal may be referred to as a pilot or pilot signal, wherein the pilot signal is used for channel estimation or channel sounding. The reference signal in this application may also be a reference signal other than those listed above that can be carried in orthogonal frequency division multiplexing (OFDM) symbols, which will not be described further here.

[0154] Reference signals are divided into uplink reference signals and downlink reference signals. Uplink reference signals refer to the signals sent by the terminal equipment to the network equipment; that is, the sender is the terminal equipment, and the receiver is the network equipment. Uplink reference signals serve two purposes: uplink channel estimation (used for coherent demodulation and detection in network equipment or for calculating precoding) and uplink channel quality measurement. Uplink reference signals can include DMRS and SRS. SRS can be used for uplink channel quality estimation and channel selection, calculating the signal-to-interference-plus-noise ratio (SINR) of the uplink channel, and obtaining uplink channel coefficients. In TDD scenarios, due to the reciprocity of uplink and downlink channels, SRS can also be used to obtain downlink channel coefficients. Based on the uplink / downlink channel coefficients estimated by the base station using SRS, the uplink / downlink precoding matrices can be determined, improving uplink / downlink transmission rates and increasing system capacity.

[0155] Taking FDD communication as an example, since uplink and downlink channels lack reciprocity or cannot guarantee reciprocity, network devices need to obtain downlink channel state information (CSI) reference signals through uplink feedback from terminal devices. Network devices typically send downlink reference signals to terminal devices, which then receive these signals. Since the terminal devices know the transmission information of the downlink reference signals, they can perform channel measurements and interference measurements based on the received signals to estimate the downlink channel traversed by the downlink reference signal. The terminal devices then generate the downlink CSI based on this measurement and the resulting downlink channel matrix.

[0156] 2. Channel Information: Channel information represents channel-related information between the network device side and the terminal device side. It is information that reflects channel characteristics and channel quality, and includes at least one of the following: channel state information, channel precoding information, channel environment information, beam information, beam angle information, beam power information, beam indication information, channel feature vector, channel eigenvalue, channel amplitude information, or channel phase information. The channel involved in this application can be an uplink channel, downlink channel, or sidelink channel, etc., and is not limited thereto.

[0157] Channel state information indicates the state of the channel. Channel precoding information indicates the precoding matrix of the channel, etc. Beam information indicates the beam used for transmitting or receiving signals, such as including the beam index. Beam angle information includes, for example, at least one of beam pointing, beamwidth, or beamforming method. Beam pointing includes, for example, the direction of the main lobe formed by beamforming. Beamwidth refers to the degree to which the main lobe formed by beamforming is broadened in space. Beamforming method refers to the method of beamforming, such as numerical methods, etc. Beam power information indicates the power of the beam. Beam indication information refers to the parameters required for beamforming. The channel eigenvector is a vector used to represent the transmission characteristics of the channel. The channel eigenvalue refers to the eigenvalue of the channel matrix. Channel amplitude information refers to the amplitude changes of the signal during transmission. Channel phase information refers to the phase changes of the signal during transmission.

[0158] 3. Port: A port, also called an antenna port, can include transmit ports and receive ports. An antenna port is a logical concept; one antenna port can correspond to one physical transmit antenna or multiple physical transmit antennas. In both cases, the terminal's receiver will not decompose signals from the same antenna port. From the terminal's perspective, regardless of whether the channel is formed by a single physical transmit antenna or by combining multiple physical transmit antennas, the reference signal (RS) corresponding to this antenna port defines it. For example, the antenna port corresponding to the demodulation reference signal (DMRS) is the DMRS port. The terminal can obtain the channel estimate for the corresponding antenna port based on the reference signal. Each antenna port corresponds to a time / frequency resource grid and has its own independent reference signal. One antenna port is one channel, and the terminal performs channel estimation and data demodulation based on the reference signal corresponding to that antenna port.

[0159] Optionally, a port refers to a port after beamforming and / or phase rotation.

[0160] An antenna port is typically associated with a reference signal (e.g., a pilot signal), and its meaning can be understood as a transmit / receive interface on the channel through which the reference signal passes. In low-frequency systems, an antenna port may correspond to one or more antenna elements that jointly transmit the reference signal; the receiver can treat them as a whole without distinguishing between individual elements. In high-frequency systems, an antenna port may correspond to a beam; similarly, the receiver only needs to treat this beam as an interface and does not need to distinguish between individual elements.

[0161] 4. Time-frequency resources: Data or information can be carried through time-frequency resources. These resources can include resources in the time domain (i.e., time-domain resources) and resources in the frequency domain (i.e., frequency-domain resources).

[0162] In the time domain, time-domain resources can include one or more time-domain units (or time units). Time-domain units can include radio frames (RF), subframes, frames, half-subframes, half-frames, slots, mini-slots, partial slots, or orthogonal frequency division multiplexing (OFDM) symbols, etc.

[0163] In the frequency domain, frequency domain resources can include one or more frequency domain units. Frequency domain units can include subcarriers, component carriers (CCs), resource elements (REs), resource blocks (RBs), subchannels, resource pools, bandwidth, bandwidth parts (BWPs), channels, or an interlaced RB, etc.

[0164] In this application, time-frequency resources include time-frequency points, and a time-frequency point can be regarded as an RE. For example, a time-frequency point includes a symbol and a subcarrier, and the symbol and the subcarrier correspond. Alternatively, a time-frequency point can also be regarded as an RB, without limitation.

[0165] 5. Linearity of transmission power:

[0166] Transmission power linearity refers to a linear representation of power, typically used to describe the magnitude of transmitted power. Transmission power linearity is usually expressed in milliwatts (mW) as the absolute value of power. It can also be referred to as the linearity of transmit power and / or the linearity of receive power.

[0167] For example, the transmission power of SRS can be expressed as: P SRS,b,f,c (i,q s The transmit power of SRS at transmission time i (in decibels relative to one milliwatt, dBm) is:

[0168] Where b represents the bandwidth part (BWP), c represents the carrier, f represents the cell where the terminal device is located, i indicates the timing of signal resource transmission, and q... s The index of the reference signal SRS is represented, and l represents the index of the signal resource power control adjustment state, where P CMAX,f,c (i) is the maximum transmit power configured for the terminal device, P o_SRS,b,f,c (q s ) represents the desired received power configured by the network side for the terminal device, μ represents the subcarrier spacing, and M represents the desired received power. SRD,b,f,c (i) represents the bandwidth of the SRS, α SRS,b,f,c (q s ) represents the road loss factor, PL b,f,c (q s ) is the downlink reference signal q measured by the terminal device. sRoad loss, in dB, h b,f,c If (i,l) represents the closed-loop power control adjustment state, then the linear value of the transmission power of the SRS can be expressed as:

[0169] The above description of the terminology is for ease of understanding only and does not limit the scope of protection of the embodiments of this application.

[0170] The current protocol defines four uses of SRS, including antenna switching, codebook, noncodebook, and beam management. Among them, antenna switching SRS is used to detect downlink channel information.

[0171] It should be noted that antenna switching in this application can also be called antenna selection, and there is no limitation on it.

[0172] For example, in the transmission of antenna switching SRS, the network device configures one or more SRS resource sets with usage of antenna switching for the UE based on the antenna switching capability reported by the UE. Each resource set may include one or more SRS resources. The UE sends SRS according to the configuration parameters of one or more SRS resources, and the network device performs channel measurement and estimation based on the received SRS. It should be noted that the number of SRS ports contained in each SRS resource in the antenna switching SRS resource set is uniform. For example, for an xTyR UE, each resource set configured by the network device contains (y / x) SRS resources, and each SRS resource includes x SRS ports.

[0173] Figure 3 is a schematic diagram of a configuration scheme for multiple SRS resources included in an SRS resource set. As shown in Figure 3(a), for a 2T4R UE, this means that the UE can transmit 2 signals simultaneously or receive 4 signals simultaneously. The dashed lines can be considered as UE ports, for example, 4 ports. The network device can configure two 2-port SRS resources in the SRS resource set with usage of antenna switching based on the UE's antenna switching capability. As shown in Figure 3(b), the two 2-port SRS resources (e.g., 2-port SRS resource 0 and 2-port SRS resource 1) include the same number of SRS ports, for example, 2. Furthermore, the UE ports associated with the two 2-port SRS resources are different. For example, the solid lines can be considered as the antenna ports currently used by the UE to transmit SRS. Therefore, the UE port associated with 2-port SRS resource 0 is different from the UE port associated with 2-port SRS resource 1. In one example, the UE can transmit SRS at two different SRS transmission times (e.g., i0 and i1), enabling the network device to measure the channels corresponding to the 4 UE ports. Specifically, the UE transmits two SRS signals at time i0 and two SRS signals at time i1. The UE port used for transmitting the SRS at time i0 is different from the UE port used for transmitting the SRS at time i1. Meanwhile, to ensure consistent SRS transmission power across different ports and avoid measurement errors by network equipment, the UE can evenly distribute the linear value of the SRS transmission power across all ports of the same SRS resource. That is, the linear value of the transmission power of the two ports included in 2-port SRS resource 0 or 2-port SRS resource 1 is the same.

[0174] With the evolution of future terminal forms, UE antenna modules can be assembled in a splicing manner. In one example, the UE's antenna module is composed of a 1T2R module and a 1T4R module, forming a 2T6R antenna module. Here, 1T2R can represent that the UE supports 1 antenna port for simultaneous signal transmission and 2 antenna ports for simultaneous signal reception; 1T4R can represent that the UE supports 1 antenna port for simultaneous signal transmission and 4 antenna ports for simultaneous signal reception. Thus, this UE supports 2 antenna ports for simultaneous signal transmission and 6 antenna ports for simultaneous signal reception. Unlike the currently defined 2T6R UE, these three 2-port SRS resources cannot enable network devices to perform channel measurement and estimation for the 6 antenna ports used for receiving signals.

[0175] In another example, the UE's antenna module is composed of a 2T4R module and a 1T4R module, forming a 3T8R antenna module. Here, 2T4R can indicate that the UE supports 2 antenna ports for simultaneous signal transmission and 4 antenna ports for simultaneous signal reception; 1T4R can indicate that the UE supports 1 antenna port for simultaneous signal transmission and 4 antenna ports for simultaneous signal reception. Thus, this UE supports 3 antenna ports for simultaneous signal transmission and 8 antenna ports for simultaneous signal reception. For this type of UE, a corresponding SRS resource configuration scheme has not yet been defined.

[0176] In view of this, this application provides a communication method and apparatus that enables terminal devices to send antenna switching SRS based on the SRS resource set configured in the network device, thereby ensuring transmission performance.

[0177] The communication method provided by the embodiments of this application will be described in detail below with reference to the accompanying drawings, and can be applied to the communication system shown in Figure 1 or Figure 2 above.

[0178] It should also be understood that the embodiments shown below do not specifically limit the structure of the execution entity of the method provided in the embodiments of this application, as long as it is possible to communicate according to the method provided in the embodiments of this application by running the code or program that records the method provided in the embodiments of this application. For example, the method provided in the embodiments of this application can be executed by the network side and the terminal side. Unless otherwise specified, "network side" in this application can refer to a network device, or a component in the network device (e.g., a communication module, processor, circuit, chip, or chip system, etc.), or it can be a logic module or software that can implement all or part of the functions of the network device. "Terminal side" in this application can refer to a terminal device, or a component in the terminal device, or it can be a logic module or software that can implement all or part of the functions of the terminal device.

[0179] Optionally, the terminal side in this embodiment may also be referred to as the "UE side" or "UE part". The network side may also be referred to as the "Network side" or "Network part", and the specific names are not limited. For ease of description, the following embodiments use the interaction between the network device and the terminal device as the main entities to illustrate the process.

[0180] Figure 4 is a flowchart illustrating a communication method provided in an embodiment of this application. As shown in Figure 4, the method 400 includes the following steps; for details not covered herein, please refer to the relevant descriptions in existing solutions.

[0181] S410, the network device determines the first configuration information.

[0182] The first configuration information is used to indicate the first SRS resource set, which is used for antenna switching. The first SRS resource set includes multiple SRS resources, each of which includes multiple SRS ports. The multiple SRS resources include the first SRS resource and the second SRS resource. The first SRS port included in the first SRS resource and the second SRS port included in the second SRS resource are associated with the same terminal device port.

[0183] It is understood that the ports in the embodiments of this application include SRS ports and terminal device ports, wherein an SRS port can be understood as a logical port and a terminal device port can be understood as a physical port. Optionally, an SRS port can also be replaced with an SRS port pair, and a terminal device port can also be replaced with: UE port, or UE antenna port, UE port pair, UE antenna port pair, or UE antenna pair, or UE antenna port, or UE antenna port pair, etc., without specific limitation on their names.

[0184] For example, the first configuration information can be sent via RRC signaling or other signaling, without limitation.

[0185] For example, the first SRS resource set is used for antenna switching, indicating that the purpose of the multiple SRS resources included in the first SRS resource set is antenna switching. Here, antenna switching can also be replaced with antenna switching, and the name is not limited.

[0186] For example, each SRS resource in a plurality of SRS resources includes a plurality of SRS ports. Optionally, each SRS resource includes the same number of SRS ports, for example, each SRS resource includes 2 SRS ports or 3 SRS ports. For example, assuming that the first SRS resource set includes 4 SRS resources, then each SRS resource may include 2 SRS ports, or each SRS resource may include 3 SRS ports, without limitation.

[0187] Compared to Figure 3, where different SRS resources contain SRS ports associated with different UE ports, in this embodiment, different SRS resources contain SRS ports that can be associated with the same UE port. For example, the first SRS port contained in the first SRS resource and the second SRS port contained in the second SRS resource are associated with the same UE port, such as UE port #1. This means that UE port #1 is associated with both the first and second SRS ports, and it also means that the UE can send multiple SRSs through UE port #1, such as two SRSs. The first SRS corresponds to the first SRS port contained in the first SRS resource, and the second SRS corresponds to the second SRS port contained in the second SRS resource.

[0188] In one implementation, the first SRS resource also includes a third SRS port, and the second SRS resource also includes a fourth SRS port. The third SRS port and the fourth SRS port are associated with different terminal device ports. That is, the first SRS resource includes a first SRS port and a third SRS port, and the second SRS resource includes a second SRS port and a fourth SRS port. Assuming that the first SRS port and the second SRS port are both SRS port 0, and the third SRS port and the fourth SRS port are both SRS port 1, then the two SRS port 0s are associated with the same UE port, and the two SRS port 1s are associated with different UE ports.

[0189] In one implementation, the first SRS port and the third SRS port are associated with different terminal device ports, and the second SRS port and the fourth SRS port are associated with different terminal device ports. That is, the first SRS resource includes the first SRS port and the third SRS port, and the second SRS resource includes the second SRS port and the fourth SRS port. Assuming that the first and second SRS ports are both SRS port 0, and the third and fourth SRS ports are both SRS port 1, then the SRS port 0 and SRS port 1 included in the first SRS resource are associated with different UE ports, and the SRS port 0 and SRS port 1 included in the second SRS resource are associated with different UE ports.

[0190] For example, the first SRS port included in the first SRS resource and the second SRS port included in the second SRS resource can be associated with UE port #1, the third SRS port included in the first SRS resource can be associated with UE port #2, and the fourth SRS port included in the second SRS resource can be associated with UE port #3. That is, the first SRS port and the third SRS port included in the first SRS resource are associated with UE port #1 and UE port #2 respectively, and the third SRS port and the fourth SRS port included in the second SRS resource are associated with UE port #1 and UE port #3 respectively.

[0191] In this application, the port numbers of the SRS ports contained in the first SRS resource and the second SRS resource may include the following examples.

[0192] For example, the port numbers of the first and second SRS ports are 1000, and the port numbers of the third and fourth SRS ports are 1001; or, the port numbers of the first and second SRS ports are 1001, and the port numbers of the third and fourth SRS ports are 1000; or, the port numbers of the first and fourth SRS ports are 1000, and the port numbers of the second and third SRS ports are 1001; or, the port numbers of the first and fourth SRS ports are 1001, and the port numbers of the second and third SRS ports are 1000.

[0193] Understandably, the above examples are provided for ease of understanding only, and other possible solutions are not excluded.

[0194] Optionally, before performing step S410, the method 400 may further include: the terminal device may report the terminal device's capability information to the network device, the terminal device's capability information being used to indicate the terminal device's antenna switching capability, or in other words, to indicate the SRS transmission mode supported by the terminal device for antenna switching.

[0195] For example, the terminal device can indicate UE capabilities to the network device through the supported SRS-TxPortSwitch. Specifically, for UE antenna switching capabilities, t1r2 corresponds to 1T2R, t1r1-t1r2 corresponds to 1T=1R / 1T2R, t2r4 corresponds to 2T4R, t1r4 corresponds to 1T4R, t1r1-t1r2-t1r4 corresponds to 1T=1R / 1T2R / 1T4R, t1r4-t2r4 corresponds to 1T4R / 2T4R, and t1r1-t1r2-t1r4 corresponds to 1T=1R / 1T2R / 1T4R, t1r4-t2r4 corresponds to 1T4R / 2T4R, and t1r1-t1r2-t1r4 corresponds to 1T=1R / 1T2R / 1T4R. r2-t2r2-t2r4 corresponds to 1T=1R / 1T2R / 2T=2R / 2T4R, t1r1-t1r2-t2r2-t1r4-t2r4 corresponds to 1T=1R / 1T2R / 2T=2R / 1T4R / 2T4R, t1r1 corresponds to 1T=1R, t2r2 corresponds to 2T=2R, t1r1-t2r2 corresponds to 1T=1R / 2T=2R, t4r4 corresponds to 4T=4R, t1r1-t2r2-t4r4 corresponds to 1T=1R / 2T=2R / 4T.

[0196] Alternatively, the terminal device can indicate the UE capabilities to the network device through supportedSRS-TxPortSwitchBeyon4Rx. Specifically, for the UE antenna switching capability, t1r1 corresponds to 1T=1R, t2r2 corresponds to 2T=2R, t1r2 corresponds to 1T2R, t4r4 corresponds to 4T=4R, t2r4 corresponds to 2T4R, t1r4 corresponds to 1T4R, t2r6 corresponds to 2T6R, t1r6 corresponds to 1T6R, t4r8 corresponds to 4T8R, t2r8 corresponds to 2T8R, and t1r8 corresponds to 1T8R.

[0197] Alternatively, the terminal device can indicate the UE capability to the network device via newUECapabilitySupporting8T8R. Specifically, for UE antenna switching capability, t1r1 corresponds to 1T=1R, t2r2 corresponds to 2T=2R, t1r2 corresponds to 1T2R, t4r4 corresponds to 4T=4R, t2r4 corresponds to 2T4R, t1r4 corresponds to 1T4R, t2r6 corresponds to 2T6R, t1r6 corresponds to 1T6R, t4r8 corresponds to 4T8R, t2r8 corresponds to 2T8R, t1r8 corresponds to 1T8R, and [noTDM] or [TDM and noTDM] corresponds to 8T8R.

[0198] Optionally, the terminal device can also indicate the UE's capabilities to the network device by sending other fields, such as newly defined fields. Specifically, for the UE's antenna switching capability, t3r3 corresponds to 3T=3R, and t3r6 corresponds to 3T6R. Here, t3r3 can indicate that the UE supports 3 antenna ports for simultaneous signal transmission and 3 antenna ports for simultaneous signal reception, and t3r6 can indicate that the UE supports 3 antenna ports for simultaneous signal transmission and 6 antenna ports for simultaneous signal reception.

[0199] Understandably, this application does not limit the names of the newly defined fields; they can be used to indicate the antenna switching capability of the UE. Furthermore, the antenna ports t3r3 or t3r6 supported by the UE are merely illustrative examples for ease of understanding, and other solutions are not excluded.

[0200] Specifically, 1T2R can indicate that the terminal device supports 1 antenna port for simultaneous signal transmission and 2 antenna ports for simultaneous signal reception. 1T4R can indicate that the terminal device supports 1 antenna port for simultaneous signal transmission and 4 antenna ports for simultaneous signal reception. 1T6R can indicate that the terminal device supports 1 antenna port for simultaneous signal transmission and 6 antenna ports for simultaneous signal reception. 1T8R can indicate that the terminal device supports 1 antenna port for simultaneous signal transmission and 8 antenna ports for simultaneous signal reception. 2T4R can indicate that the terminal device supports 2 antenna ports for simultaneous signal transmission and 4 antenna ports for simultaneous signal reception. 2T6R can indicate that the terminal device supports 1 antenna port for simultaneous signal transmission and 4 antenna ports for simultaneous signal reception. The terminal device has 2 antenna ports for simultaneous signal transmission and 6 antenna ports for simultaneous signal reception. 2T8R indicates that the terminal device supports 2 antenna ports for simultaneous signal transmission and 8 antenna ports for simultaneous signal reception. 3T3R indicates that the terminal device supports 3 antenna ports for simultaneous signal transmission and 3 antenna ports for simultaneous signal reception. 3T6R indicates that the terminal device supports 3 antenna ports for simultaneous signal transmission and 6 antenna ports for simultaneous signal reception. 4T8R indicates that the terminal device supports 4 antenna ports for simultaneous signal transmission and 8 antenna ports for simultaneous signal reception. 8T8R indicates that the terminal device supports 8 antenna ports for simultaneous signal transmission and 8 antenna ports for simultaneous signal reception.

[0201] The above are merely examples for ease of understanding, and other possible solutions are not excluded. This application does not limit the number of transmitting antennas and receiving antennas of the UE, or in other words, it does not limit the number of antenna ports for simultaneous signal transmission and the number of antenna ports for simultaneous signal reception of the UE.

[0202] Furthermore, the network device can determine the first configuration information based on the capability information of the terminal device.

[0203] For example, if the terminal device's capability information indicates that the terminal device has antenna switching capability or that the antenna modules are spliced ​​together, such as m1Tn1R+m2Tn2R, then the first SRS resource set indicated by the first configuration information determined by the network device includes... There are 1 SRS resource, and each SRS resource contains m1+m2 ports, where m1, n1, m2, and n2 are all positive integers.

[0204] For example, if the terminal device's capability information indicates that the terminal device's antenna switching capability is 3T8R, then the first SRS resource set indicated by the first configuration information determined by the network device contains 4 SRS resources, and each SRS resource contains 3 ports.

[0205] For example, if the terminal device's capability information indicates that the terminal device's antenna switching capability is 2T6R, which is different from the existing protocol, then the first SRS resource set indicated by the first configuration information determined by the network device contains 4 SRS resources, and each SRS resource contains 2 ports.

[0206] For example, the capability information of the terminal device may be different fields from those of supportedSRS-TxPortSwitch, supportedSRS-TxPortSwitchBeyon4Rx, and newUECapabilitySupporting8T8R.

[0207] For example, suppose the UE's antenna module is composed of a 1T2R module and a 1T4R module, forming a 2T6R antenna module, or the UE's antenna capability is 2T6R, which differs from existing protocols. Here, 1T2R can represent that the UE supports 1 antenna port for simultaneous signal transmission and 2 antenna ports for simultaneous signal reception; 1T4R can represent that the UE supports 1 antenna port for simultaneous signal transmission and 4 antenna ports for simultaneous signal reception. Thus, the UE supports 2 antenna ports for simultaneous signal transmission and 6 antenna ports for simultaneous signal reception. Correspondingly, the first SRS resource set determined by the network device contains 4 SRS resources, each including the same number of SRS ports, for example, 2 SRS ports. In this case, the first configuration information is used to configure the 4 2-port SRS resources.

[0208] For example, suppose the UE's antenna module is composed of a 2T4R module and a 1T4R module, forming a 3T8R antenna module, or the UE's antenna capability is 3T8R. Here, 2T4R can indicate that the UE supports 2 antenna ports for simultaneous signal transmission and 4 antenna ports for simultaneous signal reception; 1T4R can indicate that the UE supports 1 antenna port for simultaneous signal transmission and 4 antenna ports for simultaneous signal reception. Thus, the UE supports 3 antenna ports for simultaneous signal transmission and 8 antenna ports for simultaneous signal reception. Correspondingly, the first SRS resource set determined by the network device contains 4 SRS resources, each SRS resource including the same number of SRS ports, for example, 3 SRS ports. In this case, the first configuration information is used to configure the 4 3-port SRS resources.

[0209] For example, for a 3T8R UE, the first SRS resource set contains four 3-port SRS resources, such as the first SRS resource, the second SRS resource, the third SRS resource, and the fourth SRS resource. Each SRS resource includes SRS port 0, SRS port 1, and SRS port 2. Specifically, SRS port 0 in the first and third SRS resources can be associated with the same UE port (e.g., the first UE port); SRS port 1 in the first and third SRS resources can be associated with the same UE port (e.g., the second UE port); SRS port 0 in the second and fourth SRS resources can be associated with the same UE port (e.g., the third UE port); and SRS port 1 in the second and third SRS resources can be associated with the same UE port (e.g., the fourth UE port).

[0210] S420, the network device sends the first configuration information to the terminal device;

[0211] Correspondingly, the terminal device receives the first configuration information from the network device.

[0212] S430, the terminal device sends SRS according to the first configuration information.

[0213] The number of SRSs can be one or more, without limitation. The correspondence between an SRS and the multiple SRS resources included in the first SRS resource set is also not limited; for example, a terminal device can send multiple SRSs on multiple SRS resources, sending one SRS on each SRS resource.

[0214] This application does not limit the specific implementation method of the terminal device sending SRS according to the first configuration information.

[0215] For example, for a 2T6R UE, the first configuration information sent by the network device indicates four SRS resources, each containing the same number of SRS ports, such as two (SRS port 0 and SRS port 1). Assuming the UE ports include UE port #1, UE port #2, UE port #3, UE port #4, UE port #5, and UE port #6, then SRS port 0 of the first and third SRS resources can be associated with the same UE port (e.g., UE port #1), SRS port 0 of the second and fourth SRS resources can be associated with the same UE port (e.g., UE port #2), SRS port 1 of the first SRS resource is associated with UE port #3, SRS port 1 of the second SRS resource is associated with UE port #4, SRS port 1 of the third SRS resource is associated with UE port #5, and SRS port 1 of the fourth SRS resource is associated with UE port #6. At SRS transmission time i1, the UE transmits SRS port 0 of the first SRS resource on UE port #1 and SRS port 1 of the first SRS resource on UE port #3; at SRS transmission time i2, the UE transmits SRS port 0 of the second SRS resource on UE port #2 and SRS port 1 of the second SRS resource on UE port #4; at SRS transmission time i3, the UE transmits SRS port 0 of the third SRS resource on UE port #1 and SRS port 1 of the third SRS resource on UE port #5; at SRS transmission time i4, the UE transmits SRS port 0 of the fourth SRS resource on UE port #1 and SRS port 1 of the fourth SRS resource on UE port #3.

[0216] For example, for a 3T8R UE, the first configuration information sent by the network device is used to indicate 4 SRS resources, each SRS resource containing the same number of SRS ports, such as 3 (SRS port 0, SRS port 1 and SRS port 2). Assuming the UE ports include UE port #1, UE port #2, UE port #3, UE port #4, UE port #5, UE port #6, UE port #7, and UE port #8, then the SRS port 0 of the first SRS resource and the third SRS resource can be associated with the same UE port (e.g., UE port #1), the SRS port 1 of the first SRS resource and the third SRS resource can be associated with the same UE port (e.g., UE port #2), the SRS port 0 of the second SRS resource and the fourth SRS resource can be associated with the same UE port (e.g., UE port #3), the SRS port 1 of the second SRS resource and the fourth SRS resource can be associated with the same UE port (e.g., UE port #4), the SRS port 2 of the first SRS resource is associated with UE port #5, the SRS port 2 of the second SRS resource is associated with UE port #6, the SRS port 2 of the third SRS resource is associated with UE port #7, and the SRS port 2 of the fourth SRS resource is associated with UE port #8. At SRS transmission timing i1, the UE transmits SRS port 0 of the first SRS resource on UE port #1, SRS port 1 of the first SRS resource on UE port #2, and SRS port 2 of the first SRS resource on UE port #5; at SRS transmission timing i2, the UE transmits SRS port 0 of the second SRS resource on UE port #3, SRS port 1 of the second SRS resource on UE port #4, and SRS port 2 of the second SRS resource on UE port #6; at SRS transmission timing i3, the UE transmits SRS port 0 of the third SRS resource on UE port #1, SRS port 1 of the third SRS resource on UE port #2, and SRS port 2 of the third SRS resource on UE port #7; at SRS transmission timing i4, the UE transmits SRS port 0 of the fourth SRS resource on UE port #3, and SRS port 2 of the fourth SRS resource on UE port #4. 1. Send the SRS port 2 of the second SRS resource on UE port #8.

[0217] In one implementation, the terminal device can send SRS according to the mapping rules between SRS ports and terminal device ports. For example, for a 2T6R UE, the first configuration information sent by the network device is used to indicate four 2-port SRS resources, each containing the same number of SRS ports, such as two (SRS port 0 and SRS port 1). Assuming the UE ports include UE port #1, UE port #2, UE port #3, UE port #4, UE port #5, and UE port #6, then SRS port 0 of the first and third SRS resources can be associated with the same UE port (e.g., UE port #1), SRS port 0 of the second and fourth SRS resources can be associated with the same UE port (e.g., UE port #2), SRS port 1 of the first SRS resource is associated with UE port #3, SRS port 1 of the second SRS resource is associated with UE port #4, SRS port 1 of the third SRS resource is associated with UE port #5, and SRS port 1 of the fourth SRS resource is associated with UE port #6. Understandably, UE ports #1 and #2 are used to transmit SRS twice, while UE ports #3, #5, and #6 are used to transmit SRS once.

[0218] The mapping rules between the SRS port and the terminal device port can be predefined or preconfigured. Predefinition can include pre-defined rules, such as protocol definitions. Preconfiguration can be achieved by pre-storing corresponding codes, tables, functions, text, strings, or other means of indicating relevant information (e.g., mapping rules) in the network device and / or terminal device. This application does not limit the specific implementation method, as long as the mapping rules are aligned between the network device and the terminal device. This allows the network device to clearly identify which terminal device ports will send SRS multiple times, thereby correctly receiving SRS and completing channel measurement and estimation.

[0219] It should be noted that the antenna switching performed by the terminal device when sending SRS is implemented internally by the UE. The specific implementation method is not limited and can be referred to existing relevant descriptions, which will not be explained here.

[0220] Figure 5 is a schematic diagram of configuring SRS resources on a network device according to an embodiment of this application.

[0221] As shown in Figure 5(a), for a 2T6R UE, this means the UE can simultaneously transmit 2 signals or simultaneously receive 6 signals. Based on the resource allocation rules described above, the network device can determine that the first SRS resource set includes four 2-port SRS resources, such as 2-port SRS resources 0 to 2-port SRS resources 3, corresponding to four SRS transmission opportunities (e.g., i0, i1, i2, i3). Therefore, each SRS resource includes the same number of SRS ports, such as two SRS ports. The solid lines in each SRS resource can be considered as the UE ports used by the UE to transmit SRS during the current transmission opportunity. Thus, it can be seen that multiple SRS resources are associated with different UE ports.

[0222] For example, assuming each SRS resource includes two SRS ports, SRS port 0 (left) and SRS port 1 (right), then SRS port 0 in the four 2-port SRS resources can be associated with the same UE port. For instance, the UE port associated with SRS port 0 in 2-port SRS resource 0 is the same as the UE port associated with SRS port 0 in 2-port SRS resource 2, and the UE port associated with SRS port 0 in 2-port SRS resource 1 is the same as the UE port associated with SRS port 0 in 2-port SRS resource 3. Optionally, the network device can configure 2-port SRS resource 0 and 2-port SRS resource 2 to belong to a first subset, and 2-port SRS resource 1 and 2-port SRS resource 3 to belong to a second subset via RRC signaling. In this case, the UE ports associated with SRS port 0 in 2-port SRS resource 0 and 2-port SRS resource 2 are the same, for example, UE port #1, and the UE ports associated with SRS port 0 in 2-port SRS resource 1 and 2-port SRS resource 3 are the same, for example, UE port #2.

[0223] Furthermore, the UE ports associated with SRS port 1 in the four 2-port SRS resources are not the same. For example, SRS port 1 in 2-port SRS resource 0 is associated with UE port #3, SRS port 1 in 2-port SRS resource 1 is associated with UE port #4, SRS port 1 in 2-port SRS resource 2 is associated with UE port #5, and SRS port 1 in 2-port SRS resource 3 is associated with UE port #6. Therefore, SRS port 0 and SRS port 1 in the same SRS resource are not associated with the same UE port. Specifically, SRS port 0 and SRS port 1 in 2-port SRS resource 0 are associated with UE ports #1 and #3 respectively, SRS port 0 and SRS port 1 in 2-port SRS resource 1 are associated with UE ports #2 and #4 respectively, SRS port 0 and SRS port 1 in 2-port SRS resource 2 are associated with UE ports #1 and #5 respectively, and SRS port 0 and SRS port 1 in 2-port SRS resource 3 are associated with UE ports #2 and #6 respectively.

[0224] As shown in Figure 5(b), for a 3T8R UE, this means the UE can simultaneously transmit 3 signals or simultaneously receive 8 signals. Based on the resource allocation rules described above, the network device can determine that the first SRS resource set includes four 3-port SRS resources, for example, 3-port SRS resources 0 to 3-port SRS resources 3, corresponding to four SRS transmission opportunities (e.g., i0, i1, i2, i3). Therefore, each SRS resource includes the same number of SRS ports, for example, three SRS ports. The solid lines in each SRS resource can be considered as the UE ports used by the UE to transmit SRS during the current transmission opportunity. Thus, it can be seen that multiple SRS resources are associated with different UE ports.

[0225] For example, assuming that each SRS resource includes three SRS ports, namely SRS port 0, SRS port 1 (left), and SRS port 2 (right), then SRS port 0 and SRS port 1 in the four 3-port SRS resources can be associated with the same UE port. For instance, the UE ports associated with SRS port 0 and SRS port 1 in 2-port SRS resource 0 are the same as those associated with SRS port 0 and SRS port 1 in 2-port SRS resource 2, and the UE ports associated with SRS port 0 and SRS port 1 in 2-port SRS resource 1 are the same as those associated with SRS port 0 and SRS port 1 in 2-port SRS resource 3. Optionally, the network device can configure 3-port SRS resources 0 and 3-port SRS resources 2 to belong to the first subset and 3-port SRS resources 1 and 3-port SRS resources 3 to belong to the second subset via RRC signaling. In this case, the UE ports associated with SRS port 0 and SRS port 1 contained in 3-port SRS resources 0 and 3-port SRS resources 2 are the same, such as UE port #1 and UE port #2. Similarly, the UE ports associated with SRS port 0 and SRS port 1 contained in 3-port SRS resources 1 and 3-port SRS resources 3 are the same, such as UE port #3 and UE port #4.

[0226] In addition, the SRS port 2 associated with each of the four 3-port SRS resources is different. For example, SRS port 3 in 3-port SRS resource 0 is associated with UE port #5, SRS port 2 in 3-port SRS resource 1 is associated with UE port #6, SRS port 2 in 3-port SRS resource 2 is associated with UE port #7, and SRS port 2 in 3-port SRS resource 3 is associated with UE port #8. Therefore, it can be seen that SRS port 0, SRS port 1, and SRS port 2 in the same SRS resource are associated with different UE ports. Specifically, SRS port 0, SRS port 1, and SRS port 2 in 3-port SRS resource 0 are associated with UE ports #1, #2, and #5, respectively; SRS port 0, SRS port 1, and SRS port 2 in 3-port SRS resource 1 are associated with UE ports #3, #4, and #6, respectively; SRS port 0, SRS port 1, and SRS port 2 in 3-port SRS resource 2 are associated with UE ports #1, #2, and #7, respectively; and SRS port 0, SRS port 1, and SRS port 2 in 3-port SRS resource 3 are associated with UE ports #3, #4, and #8, respectively.

[0227] It should be noted that, in order to ensure that the transmit power of different SRS ports is consistent and to avoid measurement errors, the UE can evenly distribute the linear value of the SRS transmission power across all ports of the same SRS resource. That is to say, in the four 2-port SRS resources in Figure 5(a) above, the linear value of the transmission power of each of the two ports contained in each 2-port SRS resource is the same, and in the four 3-port SRS resources in Figure 5(b) above, the linear value of the transmission power of each of the three ports contained in each 3-port SRS resource is the same.

[0228] Based on the above scheme, the network device sends first configuration information to indicate the first SRS resource set, wherein the first SRS resource set includes the first SRS resource and the second SRS resource. The first SRS port in the first SRS resource and the second SRS port in the second SRS resource can be associated with the same UE port, which enables different types of terminals to send antenna switching SRS, ensuring that the network device can receive all SRS and complete channel measurement and estimation, while ensuring transmission performance.

[0229] Figure 6 is a flowchart illustrating a communication method provided in an embodiment of this application. As shown in Figure 6, the method 600 includes the following steps; for details not covered herein, please refer to the relevant descriptions in existing solutions.

[0230] S610, the network device determines the second configuration information.

[0231] The second configuration information is used to indicate the first SRS resource set, which is used for antenna switching. The first SRS resource set includes multiple SRS resources, each of which includes at least one SRS port. The multiple SRS resources include the first SRS resource and the second SRS resource. The linearity of the transmission power of the second SRS resource is 1 / N of the linearity of the transmission power of the first SRS resource, where N is an integer greater than 1.

[0232] It is understood that the ports in the embodiments of this application include SRS ports and terminal device ports, wherein an SRS port can be understood as a logical port and a terminal device port can be understood as a physical port. Optionally, an SRS port can also be replaced with an SRS port pair, and a terminal device port can also be replaced with: UE port, or UE antenna port, UE port pair, UE antenna port pair, or UE antenna pair, etc., without specific limitation on their names.

[0233] For example, the second configuration information can be sent via RRC signaling or other signaling, without limitation.

[0234] For example, the first SRS resource set is used for antenna switching, indicating that the purpose of the multiple SRS resources included in the first SRS resource set is antenna switching. Here, antenna switching can also be replaced with antenna switching, and the name is not limited.

[0235] For example, each of the multiple SRS resources includes one or more SRS ports. Optionally, there may be multiple SRS resources that include different numbers of SRS ports. For instance, assuming the first SRS resource set includes 4 SRS resources, SRS resource 0 and SRS resource 1 may each include 2 SRS ports, and SRS resource 2 and SRS resource 3 may each include 1 SRS port, without limitation.

[0236] In one implementation, the number of SRS ports contained in the first SRS resource is different from the number of SRS ports contained in the second SRS resource.

[0237] In this embodiment, the linear values ​​of transmission power for different SRS resources containing different numbers of SRS ports are different, and the relationship between the linear values ​​of transmission power for different SRS resources depends on the number of SRS ports contained in each SRS resource. For example, the first SRS resource includes m1 SRS ports, and the second SRS resource includes m2 SRS ports, where m1 ≠ m2, and N = m1 / m2, where m1 and m2 are both positive integers.

[0238] Compared to the multiple SRS resources shown in Figure 3, where each SRS resource contains the same number of SRS ports (e.g., 2 SRS ports), in this embodiment, at least two SRS resources may contain different numbers of SRS ports. For example, the first SRS resource may contain m1 (e.g., m1 = 2) first SRS ports, and the second SRS resource may contain m2 (e.g., m2 = 1) second SRS ports.

[0239] Compared to the multiple SRS resources shown in Figure 3, where each SRS resource contains two SRS ports with the same linear transmission power value (e.g., P0), this embodiment introduces a new SRS power allocation mechanism: different SRS resources containing different numbers of SRS ports have different linear transmission power values. In other words, to ensure that the transmit power of different SRS ports is aligned and to avoid measurement errors, different SRS resources can be configured to have different linear transmission power values. For example, the first SRS resource contains m1 (e.g., m1 = 2) first SRS ports, and the second SRS resource contains m2 (e.g., m2 = 1) second SRS ports. The linear transmission power value of the first SRS resource is N = m1 / m2 times the linear transmission power value of the second SRS resource.

[0240] Optionally, before performing step S610, the method 600 may further include: the terminal device may report the terminal device's capability information to the network device, the terminal device's capability information being used to indicate the terminal device's antenna switching capability, or in other words, to indicate the SRS transmission mode supported by the terminal device for antenna switching, the specific implementation of which can be referred to the relevant description of the method 400 above.

[0241] Furthermore, the network device can determine the second configuration information based on the capability information of the terminal device.

[0242] For example, if the terminal device's capability information indicates that the terminal device supports m1Tn1R+m2Tn2R, then the first SRS resource set indicated by the second configuration information determined by the network device includes... There are 1 SRS resource, where m1, n1, m2, and n2 are all positive integers.

[0243] For example, if the terminal device's capability information indicates that the terminal device's antenna switching capability is 3T8R, then the first SRS resource set indicated by the first configuration information determined by the network device contains 4 SRS resources, and each SRS resource contains 3 ports.

[0244] For example, if the terminal device's capability information indicates that the terminal device's antenna switching capability is 2T6R, which is different from the existing protocol, then the first SRS resource set indicated by the first configuration information determined by the network device contains 4 SRS resources, and each SRS resource contains 2 ports.

[0245] For example, the capability information of the terminal device may be different fields from those of supportedSRS-TxPortSwitch, supportedSRS-TxPortSwitchBeyon4Rx, and newUECapabilitySupporting8T8R.

[0246] For example, suppose the UE's antenna module is composed of a 1T2R module and a 1T4R module, forming a 2T6R antenna module, or the UE's antenna capability is 2T6R, which differs from existing protocols. Here, 1T2R can indicate that the UE supports 1 antenna port for simultaneous signal transmission and 2 antenna ports for simultaneous signal reception; 1T4R can indicate that the UE supports 1 antenna port for simultaneous signal transmission and 4 antenna ports for simultaneous signal reception. Thus, the UE supports 2 antenna ports for simultaneous signal transmission and 6 antenna ports for simultaneous signal reception. Correspondingly, the second configuration information determined by the network device is used to indicate a first SRS resource set, which contains 4 SRS resources, such as two 2-port SRS resources and two 1-port SRS resources; that is, the number of SRS ports contained in the 4 SRS resources can be different.

[0247] For example, suppose the UE's antenna module is composed of a 2T4R module and a 1T4R module, forming a 3T8R antenna module, or the UE's antenna capability is 3T8R, which differs from existing protocols. Here, 2T4R can indicate that the UE supports 2 antenna ports for simultaneous signal transmission and 4 antenna ports for simultaneous signal reception; 1T4R can indicate that the UE supports 1 antenna port for simultaneous signal transmission and 4 antenna ports for simultaneous signal reception. Thus, the UE supports 3 antenna ports for simultaneous signal transmission and 8 antenna ports for simultaneous signal reception. Correspondingly, the second configuration information determined by the network device is used to indicate a first SRS resource set, which contains 4 SRS resources, such as two 3-port SRS resources and two 1-port SRS resources; that is, the number of SRS ports contained in the 4 SRS resources can be different.

[0248] S620, the network device sends the second configuration information to the terminal device;

[0249] Correspondingly, the terminal device receives the second configuration information from the network device.

[0250] S630, the terminal device sends SRS according to the second configuration information.

[0251] The number of SRSs can be one or more, without limitation. The correspondence between an SRS and the multiple SRS resources included in the first SRS resource set is also not limited; for example, a terminal device can send multiple SRSs on multiple SRS resources, sending one SRS on each SRS resource.

[0252] This application does not limit the specific implementation method of the terminal device sending SRS according to the second configuration information.

[0253] In one implementation, the terminal device can send SRS according to the SRS power allocation mechanism.

[0254] For example, for a 2T6R UE, the second configuration information sent by the network device indicates two 2-port SRS resources (first SRS resource and second SRS resource) and two 1-port SRS resources (third SRS resource and fourth SRS resource). The two 2-port SRS resources have the same linear transmission power, the two 1-port SRS resources have the same linear transmission power, and the linear transmission power of the 1-port SRS resource is half that of the 2-port SRS resource. Therefore, assuming the linear transmission power of the terminal device transmitting SRS on the 2-port SRS resource is P0, then the linear transmission power of the SRS transmitted on the 1-port SRS resource is P0 / 2. Specifically, at SRS transmission time i1, the UE transmits the first SRS resource, at which time the linear transmission power of the SRS is... At SRS transmission time i2, the UE sends the second SRS resource, at which point the linear value of the SRS transmission power is... At SRS transmission time i3, the UE sends the third SRS resource, at which point the linear value of the SRS transmission power is... At SRS transmission time i4, the UE sends the fourth SRS resource, at which point the linear value of the SRS transmission power is... in

[0255] For example, for a 3T8R UE, the second configuration information sent by the network device indicates two 3-port SRS resources (first SRS resource and second SRS resource) and two 1-port SRS resources (third SRS resource and fourth SRS resource). The two 3-port SRS resources have the same linear transmission power, the two 1-port SRS resources have the same linear transmission power, and the linear transmission power of the 1-port SRS resource is one-third of the linear transmission power of the 3-port SRS resource. Therefore, assuming the linear transmission power of the terminal device transmitting SRS on the 3-port SRS resource is P0, then the linear transmission power of the SRS transmitted on the 1-port SRS resource is P0 / 3. Specifically, at SRS transmission time i1, the UE transmits the first SRS resource, at which time the linear transmission power of the SRS is... At SRS transmission time i2, the UE sends the second SRS resource, at which point the linear value of the SRS transmission power is... At SRS transmission time i3, the UE sends the third SRS resource, at which point the linear value of the SRS transmission power is... At SRS transmission time i4, the UE sends the fourth SRS resource, at which point the linear value of the SRS transmission power is... in

[0256] The SRS power allocation mechanism can be predefined or preconfigured. Predefinition can include pre-defined parameters, such as protocol definitions. Preconfiguration can be achieved by pre-storing corresponding codes, tables, functions, text, strings, or other means that can be used to indicate relevant information (e.g., the SRS power allocation mechanism) in network devices and / or terminal devices. This application does not limit the specific implementation method, as long as the network devices and terminal devices are aligned with the SRS power allocation mechanism.

[0257] It should be noted that the antenna switching performed by the terminal device when sending SRS is implemented internally by the UE. The specific implementation method is not limited and can be referred to existing relevant descriptions, which will not be explained here.

[0258] Figure 7 is a schematic diagram of another network device configuration for SRS resources provided in an embodiment of this application.

[0259] As shown in Figure 7(a), for a 2T6R UE, this means the UE can simultaneously transmit 2 signals or simultaneously receive 6 signals. Based on the resource allocation rules described above, the network device can determine that the first SRS resource set includes two 2-port SRS resources (e.g., 2-port SRS resource 0 and 2-port SRS resource 1) and two 1-port SRS resources (e.g., 1-port SRS resource 0 and 1-port SRS resource 1), corresponding to four SRS transmission opportunities (e.g., i0, i1, i2, i3). Both 2-port SRS resources include the same number of SRS ports (e.g., 2 SRS ports), and both 1-port SRS resources include the same number of SRS ports (e.g., 1 SRS port). That is, the SRS ports included in the four SRS resources can be different. The solid lines in each SRS resource can be considered as the UE ports used by the UE to transmit SRS during the current transmission opportunity.

[0260] For example, the linear value of the transmission power of port 1 SRS resource 0 corresponding to SRS transmission timing i2 can be half of the linear value of the transmission power of port 2 SRS resource 0 corresponding to SRS transmission timing i0, and the linear value of the transmission power of port 1 SRS resource 1 corresponding to SRS transmission timing i3 can be half of the linear value of the transmission power of port 2 SRS resource 1 corresponding to SRS transmission timing i1. Specifically, if the linear value of the transmission power of port 2 SRS resource 0 and port 2 SRS resource 1 is P0, then the linear value of the transmission power of port 1 SRS resource 0 and port 1 SRS resource 1 is P0 / 2.

[0261] As shown in Figure 7(b), for a 3T8R UE, this means the UE can simultaneously transmit 3 signals or simultaneously receive 8 signals. Based on the resource allocation rules described above, the network device can determine that the first SRS resource set includes two 3-port SRS resources (e.g., 3-port SRS resource 0 and 3-port SRS resource 1) and two 1-port SRS resources (e.g., 1-port SRS resource 0 and 1-port SRS resource 1), corresponding to four SRS transmission opportunities (e.g., i0, i1, i2, i3). The two 3-port SRS resources each include the same number of SRS ports (e.g., 3 SRS ports), and the two 1-port SRS resources each include the same number of SRS ports (e.g., 1 SRS port). That is, the SRS ports included in the four SRS resources can be different. The solid lines in each SRS resource can be considered as the UE ports used by the UE to transmit SRS during the current transmission opportunity.

[0262] For example, the linear value of the transmission power of port 1 SRS resource 0 corresponding to SRS transmission timing i2 can be one-third of the linear value of the transmission power of port 3 SRS resource 0 corresponding to SRS transmission timing i0, and the linear value of the transmission power of port 1 SRS resource 1 corresponding to SRS transmission timing i3 can be one-third of the linear value of the transmission power of port 3 SRS resource 1 corresponding to SRS transmission timing i1. Specifically, if the linear value of the transmission power of port 3 SRS resource 0 and port 3 SRS resource 1 is P0, then the linear value of the transmission power of port 1 SRS resource 0 and port 1 SRS resource 1 is P0 / 3.

[0263] Based on the above scheme, the network device indicates the first SRS resource set by sending the second configuration information. The first SRS resource set includes the first SRS resource and the second SRS resource. Multiple SRS resources can contain different numbers of SRS ports. The linear value of the transmission power of the second SRS resource is 1 / N of the linear value of the transmission power of the first SRS resource. By introducing a new SRS power allocation mechanism to constrain the transmission power of different SRS resources contained in the first SRS resource set, different types of terminals can be enabled to send antenna switching SRS, ensuring that the network device can receive all SRS and complete channel measurement and estimation, while ensuring transmission performance.

[0264] As described above, the network device (e.g., RAN) involved in the technical solution of this application can be O-RAN. In the O-RAN architecture, the RAN intelligent controller (RIC) can directly control both the gNB-CU and the gNB-DU, requiring the "network device" in the communication method shown in Figure 4 or Figure 6 to be expanded to "CU" and "DU". Optionally, in various embodiments of this application, if the network device is a CU-DU separated architecture, after the CU receives information from a core network element (e.g., AMF), it can forward the information to the DU; or, after the DU receives information from the UE, it can forward the information to the CU. The remaining steps can be referred to the relevant descriptions in Figure 4 or Figure 6 above, and will not be repeated here.

[0265] In one implementation, in step S420 of the above method 400, the CU can first send the first configuration information that needs to be sent to the terminal device to the DU, then the DU forwards it to the RU, and finally the RU sends it to the terminal device. For the specific interpretation of the first configuration information and the specific implementation of each step, please refer to the relevant description of the above method 400. For the sake of brevity, it will not be explained here.

[0266] In another implementation, in step S620 of method 600 above, the CU can first send the second configuration information that needs to be sent to the terminal device to the DU, then the DU forwards it to the RU, and finally the RU sends it to the terminal device. For the specific interpretation of the second configuration information and the specific implementation of each step, please refer to the relevant description of method 600 above. For the sake of brevity, it will not be explained here.
