In the text description of the present application, the character " / " generally indicates that the previous and next associated objects are in an "or" relationship; in the formula of the present application, the character " / " indicates that the previous and next associated objects are in a "division" relationship. "Including at least one of A, B and C" can mean: including A; including B; including C; including A and B; including A and C; including B and C; including A, B and C.

[0086] The technical solution provided in the embodiments of the present application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD), fifth generation (5G) system or new radio (NR). In addition, it can also be applied to subsequent evolution systems, such as the sixth generation 6G communication system.

[0087] The following is an introduction to the system architecture of the embodiment of the present application. It should be noted that the system architecture and business scenarios described in this application are intended to more clearly illustrate the technical solution of this application, and do not constitute a limitation on the technical solution provided by this application. It is known to those skilled in the art that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by this application is also applicable to similar technical problems.

[0088] See also Figure 1 , Figure 1It is a schematic diagram of the architecture of a communication system provided in an embodiment of the present application. It should be understood that Figure 1 The figure shows a ground communication system to which the technical solution provided by the present application is applicable. Figure 1 As shown, the communication system 10 may include a radio access network (RAN) 100 and a core network (CN) 130. The RAN 100 includes at least one RAN node (e.g., Figure 1 110a and 110b) and at least one terminal (such as Figure 1 RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment ( Figure 1 The terminal is connected to the RAN node in a wireless manner. The RAN node is connected to the core network 130 in a wireless or wired manner. The core network device in the core network 130 and the RAN node in the RAN 100 can be different physical devices, or the same physical device that integrates the core network logical function and the radio access network logical function.

[0089] RAN 100 may be a cellular system related to the third generation partnership project (3GPP), for example, a 4G, 5G mobile communication system, or a future-oriented evolution system. RAN 100 may also be an open access network (open RAN, O-RAN or ORAN), a cloud radio access network (cloud radio access network, CRAN), or a wireless fidelity (wireless fidelity, WiFi) system. RAN 100 may also be a communication system that integrates two or more of the above systems.

[0090] exist Figure 1 In the communication system shown, the RAN node, which may also be sometimes referred to as an access network device, a network device, a RAN entity or an access node, etc., constitutes a part of the communication system to help the terminal achieve wireless access. The multiple RAN nodes in the communication system 10 may be nodes of the same type or nodes of different types. In some scenarios, the roles of the RAN node and the terminal are relative, for example, Figure 1 The network element 120i may be a helicopter or a drone, which may be configured as a mobile base station. For the terminals 120j that access the RAN 100 through the network element 120i, the network element 120i is a base station. However, for the base station 110a, the network element 120i is a terminal. RAN nodes and terminals are sometimes referred to as communication devices, for example Figure 1The network elements 110a and 110b may be understood as communication devices having base station functions, and the network elements 120a-120j may be understood as communication devices having terminal functions.

[0091] In one possible scenario, a RAN node may be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a base station in a future mobile communication system, or an access node in a WiFi system. A RAN node may be a macro base station (e.g. Figure 1 110a in), micro base stations or indoor stations (such as Figure 1 110b in the figure), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the RAN node may also be a server, a wearable device, a vehicle or an on-board device, etc. For example, the access network device in the vehicle to everything (V2X) technology may be a road side unit (RSU). All or part of the functions of the RAN node in the present application may also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (such as a cloud platform). The RAN node may also be provided with a communication module, circuit or chip that performs corresponding communication functions. The RAN node may also be configured with program instructions for performing corresponding communication functions and corresponding program instructions. The RAN node in the present application may also be a logical node, a logical module or software that can implement all or part of the functions of the RAN node.

[0092] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, and different RAN nodes respectively implement part of the functions of the base station. For example, the RAN node can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set separately, or can also be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU) or a remote radio head (RRH).

[0093] exist Figure 1 In the communication system shown, the terminal (i.e., terminal) can be a device or module that accesses the above communication system and has corresponding communication functions. The terminal can also be called terminal equipment, user equipment (UE), mobile station, mobile terminal, etc. The terminal can be widely used in various scenarios, for example, device-to-device (D2D), vehicle to everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, automatic driving, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a mechanical arm, a smart home device, a transport vehicle with wireless communication function, a communication module, etc. The embodiments of the present application do not limit the device form of the terminal. The terminal is usually provided with a communication module, a circuit or a chip that performs the corresponding communication function. The terminal is also configured with program instructions for performing the corresponding communication function.

Figure 2As shown, the communication system 20 may include at least one terminal device 210 and at least one network device 220. Exemplarily, the terminal device 210 may include a terminal device 210a and / or a terminal device 210b, and the network device 220 may include a satellite 220a and / or a satellite 220b. The network device 220 may communicate with the terminal device 210 directly, or may communicate with the terminal device 210 through a relay station, such as a relay satellite. It should be understood that the network device 220 may include one or more satellites. The satellite may provide communication services, navigation services, positioning services, etc. to the terminal device through multiple beams. The satellite uses multiple beams to cover the service area, and different beams may communicate through one or more of time division, frequency division, and space division. Intersatellite links may be established between satellites, and the satellites may process and forward data according to the protocol. The communication system 20 may also include a connection device 230, such as a gateway, wherein the network device 220 may communicate with the connection device 230, and the connection device 230 may communicate with the core network 240. It should be understood that Figure 2 This is just an example. In actual scenarios, the communication system 20 may also include other types of network devices and / or other types of terminal devices, or the communication system 20 may also include more or fewer satellites, more or fewer terminal devices. In possible scenarios, the network devices may also include other non-ground devices (or flying devices), such as drones.

[0098] It should be understood that Figure 1 In the communication system 10 shown in the figure, the solution provided in the embodiment of the present application can be implemented by the RAN node and the terminal in the communication system 10 in collaboration. Figure 2 In the communication system shown, the solution provided by the present application can be implemented by the terminal device 210 and the network device 220 in the communication system 20. For ease of understanding, in the embodiments of the present application, the network device and the terminal device will be used as examples for explanation.

[0099] In the embodiments of the present application, the method executed by the network device may also be implemented by functional components inside the network device, such as a chip, a chip system, a processor, a circuit, etc. Similarly, the method executed by the terminal device may also be implemented by functional components inside the terminal device, such as a chip, a chip system, a processor, a circuit, etc.

[0100] In the existing scheme, a beam is usually configured to be associated with one or more SRS resources, that is, the same beam is used when transmitting SRS on one or more SRS resources. However, this transmission mode in which one or more SRS resources are associated with the same beam has the problem of low utilization of beam resources, which affects the transmission quality of SRS. Therefore, the technical problem to be solved by the present application is: how to improve the utilization of beam resources in the process of transmitting SRS.

[0101] In combination with the above content, the communication method of the embodiment of the present application is exemplarily introduced below.

[0102] See also Figure 3 , Figure 3 is a flow chart of a communication method provided in an embodiment of the present application. Optionally, Figure 3 The communication method shown can be applied to Figure 1 or Figure 2 The communication system shown in FIG. Figure 3 As shown, the communication method may include the following steps:

[0103] S301, a terminal device sends terminal device capability information to a network device. Correspondingly, the network device receives the terminal device capability information.

[0104] In some feasible implementations, the terminal device may generate terminal device capability information and send the terminal device capability information to the network device.

[0105] The terminal device capability information may be used to indicate that the terminal device supports at least one first signal resource associated with multiple beams. That is, one first signal resource may be associated with multiple different beams, or each of the multiple first signal resources may be associated with different beams.

[0106] It should be noted that the first signal resource may be used to transmit the first signal. Specifically, the first signal resource may include frequency domain resources and time domain resources corresponding to the transmission of the first signal.

[0107] Optionally, the first signal may be an SRS. Accordingly, in this case, the first signal resource may be referred to as an SRS resource. In possible scenarios, the first signal may also be other reference signals in the communication system, such as a positioning reference signal (PRS). The present application embodiment is not limited to this. For ease of understanding, the following description is made by taking the first signal resource as an SRS resource as an example.

[0108] Optionally, the at least one SRS resource may be included in the same SRS resource set.

[0109] In the embodiment of the present application, associating an SRS resource with a beam means that the terminal device can send SRS on the SRS resource through the beam, or in other words, the beam can be the transmission beam used by the terminal device when sending SRS on the SRS resource.

[0110] It can be understood that when the terminal device sends an SRS on at least one SRS resource, the corresponding propagation paths are different. In other words, the terminal device capability information can be used to indicate the spatial association relationship capability of at least one SRS resource.

[0111] For example, see Figure 4 , Figure 4 This is a schematic diagram of the association between an SRS resource and a beam provided in an embodiment of the present application. Here, SRS resource 1 and SRS resource 2 in the same SRS resource set are taken as examples to illustrate different beams associated with different SRS resources. Assume that the terminal device and the network device are in a spatial rectangular coordinate system composed of an x-axis, a y-axis, and a z-axis, wherein the network device is located in the z-axis direction and the terminal device is located at an arbitrary position in space. It is assumed here that SRS resource 1 is used to transmit the first SRS and SRS resource 2 is used to transmit the second SRS. Figure 4 As shown, the terminal device can send the first SRS through beam 1, that is, SRS resource 1 is associated with beam 1. The terminal device can also send the second SRS through beam 2, that is, SRS resource 2 is associated with beam 2. Among them, the propagation path corresponding to beam 1 covers the direct path between the terminal device and the network device, which can be called the first path. The propagation path corresponding to beam 2 can cover the reflection path through the ground between the terminal device and the network device, which can be called the non-first path.

[0112] Optionally, the above-mentioned terminal device supports at least one SRS resource being associated with multiple beams, which may include at least one of the following three situations: the terminal device supports at least one SRS resource being associated with multiple beams on at least one frequency band; when the terminal device transmits SRS through carrier aggregation, it supports at least one SRS resource being associated with multiple beams on multiple component carriers participating in carrier aggregation; when the terminal device is in an RRC inactive state, it supports at least one SRS resource being associated with multiple beams.

[0113] In an optional implementation, the terminal device capability information may be carried in LPP signaling or RRC signaling. In possible scenarios, the terminal device capability information may also be carried in other signaling, which is not limited in the embodiments of the present application.

[0114] The following is an illustrative introduction to three possible implementation methods of carrying terminal device capabilities in LPP signaling or RRC signaling.

[0115] Method 1: When the terminal device capability information is used to indicate that the terminal device supports at least one SRS resource associated with multiple beams on at least one frequency band, the terminal device capability information can be carried in the first field in the LPP signaling.

[0116] It should be noted that the fields of the present application may also be referred to as information elements (IEs), which are not limited in the embodiments of the present application.

[0117] Optionally, the first field may be called a spatialRelation-path field. It should be understood that the first field is a field that can be used to indicate that the terminal device supports at least one SRS resource associated with multiple beams on at least one frequency band. In possible scenarios, the first field may also have other names, which are not limited in the embodiments of the present application.

[0118] Optionally, the first field may be included in the SRS-CapabilityPerBand-r16 (sounding reference signal-band capability, referred to as band capability) field in the LPP signaling. The SRS-CapabilityPerBand-r16 field may be used to indicate the capability of the terminal device to send SRS on each frequency band, such as the frequency range and transmission beam used by the terminal device when sending SRS on each frequency band.

[0119] That is to say, a first field may be added to the SRS-CapabilityPerBand-r16 field to indicate that the terminal device supports at least one SRS resource associated with multiple beams on at least one frequency band.

[0120] Exemplarily, the SRS-CapabilityPerBand-r16 field may include the following information:

[0121]

[0122] It should be noted that the above-mentioned SRS-CapabilityPerBand-r16 field may be included in the NR-UL-SRS-Capability-r16 (New Radio Interface-Uplink-Sounding Reference Signal-Capability, referred to as Uplink Sounding Reference Signal Capability) field in the LPP signaling. Exemplarily, the NR-UL-SRS-Capability-r16 field may include the following information:

[0123]

[0124] Method 2: When the terminal device capability information is used to indicate that at least one SRS resource is supported to be associated with multiple beams on multiple component carriers participating in carrier aggregation, the terminal device capability information may be carried in the second field in the RRC signaling.

[0125] Optionally, the second field may be called a spatialRelation-path field. It should be understood that the second field is a field that can be used to indicate that, when a terminal device transmits SRS by means of carrier aggregation, it supports at least one SRS resource associated with multiple beams on multiple component carriers participating in carrier aggregation. In possible scenarios, the second field may also have other names, which is not limited in the embodiments of the present application.

[0126] Optionally, the second field may be included in the FeatureSetUplink (uplink feature set, referred to as uplink feature set) field in the RRC signaling. That is, a second field may be added to the FeatureSetUplink field to indicate that when the terminal device transmits SRS by means of carrier aggregation, it supports at least one SRS resource associated with multiple beams on multiple component carriers participating in the carrier aggregation.

[0127] For example, the FeatureSetUplink field may include the following information:

[0128]

[0129] It should be noted that the FeatureSetUplink field may be included in the FeatureSets field. The FeatureSets field may be used to indicate the ability of the terminal device to send SRS on different component carriers.

[0130] Among them, the FeatureSets field may be included in the UE-NR-Capability (terminal equipment-new air interface-capability, referred to as terminal equipment capability) field. Exemplarily, the UE-NR-Capability field may include the following information:

[0131]

[0132]

[0133] Method three, the terminal device capability information is used to indicate that the terminal device supports at least one SRS resource and multiple beams when it is in an RRC inactive state. The terminal device capability information can be carried in the third field in the RRC signaling.

[0134] Optionally, the third field may be called a spatialRelation-path-Inactive (spatial association relationship of the path level in an inactive state) field. It should be understood that the third field is a field that can be used to indicate that the terminal device supports at least one SRS resource associated with multiple beams when it is in an RRC inactive state. In possible scenarios, the third field may also have other names, which is not limited in the embodiments of the present application.

[0135] Optionally, the third field may be included in the BandNR (new radio frequency band) field in the RRC signaling. The BandNR field may include the configuration information of the SRS of the terminal device in the RRC inactive state. That is, a third field may be added to the BandNR field to indicate that the terminal device supports at least one SRS resource associated with multiple beams when it is in the RRC inactive state.

[0136] Exemplarily, the BandNR field may include the following information:

[0137]

[0138] It should be noted that the BandNR field may be included in the RF-Parameters field in the RRC signaling. The RF-Parameters field may be used to indicate the radio frequency (RF)-related capabilities of the terminal device, such as the frequency bands supported by the terminal device.

[0139] Exemplarily, the RF-Parameters field may include the following information:

[0140]

[0141] It should be noted that the above RF-Parameters field may also be included in the UE-NR-Capability field in the RRC signaling described above. Here, examples of the UE-NR-Capability field can be found in the relevant content above, and will not be repeated here.

[0142] S302: The network device sends first configuration information to the terminal device. Correspondingly, the terminal device receives the first configuration information.

[0143] In some feasible implementations, after receiving the terminal device capability information reported by the terminal device, the network device may generate first configuration information and send the first configuration information to the terminal device. Here, the first configuration information may be used to configure at least one first SRS resource, and the at least one first SRS resource may be associated with multiple different first beams.

[0144] In a possible implementation manner, the at least one first SRS resource may be determined by the network device based on the terminal device capability information.

[0145] Optionally, the at least one first SRS resource may be included in the same first SRS resource set.

[0146] In a possible implementation, after receiving the terminal capability information, the network device may determine a first SRS resource set from multiple SRS resource sets according to the terminal device capability information, and may further determine at least one first SRS resource included in the first SRS resource set. Further, the network device may associate a different first beam with each first SRS resource in the at least one first SRS resource, and may further generate first configuration information, and send the first configuration information to the terminal device.

[0147] The above-mentioned multiple SRS resource sets may be pre-configured by the network device or agreed upon by the protocol, which is not limited in the embodiments of the present application.

[0148] Optionally, the first configuration information may include first sub-configuration information and second sub-configuration information. The first sub-configuration information may be used to indicate at least one first SRS resource included in the first SRS resource set. The second sub-configuration information may be used to indicate that at least one first SRS resource is associated with a plurality of different first beams.

[0149] In an optional implementation, after receiving the above-mentioned terminal device capability information, the network device may determine a first SRS resource set from multiple SRS resource sets according to the terminal device capability information, and may further generate first sub-configuration information based on at least one first SRS resource included in the first SRS resource set. The network device may also generate the above-mentioned second sub-configuration information according to the association relationship between each first SRS resource in the at least one first SRS resource and different first beams.

[0150] Correspondingly, after receiving the above-mentioned first configuration information, the terminal device can determine at least one first SRS resource according to the first configuration information, and determine that the at least one first SRS resource can be associated with different first beams.

[0151] In the above implementation, the terminal device can report to the network device its ability to support at least one SRS resource associated with multiple beams. Further, the network device can configure at least one SRS resource that can be associated with multiple different beams for the terminal device based on the ability. In this way, the method provided by the present application can realize the transmission of SRS on at least one SRS resource through multiple different beams, avoiding the transmission of SRS on at least one SRS resource through the same beam, thereby improving the utilization rate of beam resources in the process of transmitting SRS and ensuring the transmission quality of SRS.

[0152] For ease of understanding, the following takes the above-mentioned first configuration information being used to configure the first SRS resource i1 and the first SRS resource i2, and the first SRS resource i1 being associated with the first beam j1, and the first SRS resource i2 being associated with the first beam j2 as an example to exemplarily illustrate the process of transmitting SRS on the first SRS resource through the first beam.

[0153] For some possible implementations, see Figure 5 , Figure 5 FIG. 1 is a flow chart of another communication method provided in an embodiment of the present application. It should be understood that step S303 and step S304 can be performed after step S302. Figure 5 As shown, the communication method may further include step S303 and step S304.

[0154] S303, the terminal device sends a first SRS on the first SRS resource i1 through the first beam j1. Correspondingly, the network device receives the first SRS on the first SRS resource i1 through the first beam j1.

[0155] In some feasible implementations, after determining that the first SRS resource i1 is associated with the first beam j1 according to the first configuration information, the terminal device may send the first SRS on the first SRS resource i1 through the first beam j1.

[0156] Accordingly, the network device may receive the first SRS on the first SRS resource i1 through the first beam j1.

[0157] S304, the terminal device sends a second SRS on the first SRS resource i2 via the first beam j2. Correspondingly, the network device receives the second SRS on the first SRS resource i2 via the first beam j2.

[0158] In some feasible implementations, after the terminal device determines that the first SRS resource i2 is associated with the first beam j2 according to the first configuration information, the terminal device may send the second SRS on the first SRS resource i2 through the first beam j2.

[0159] Accordingly, the network device may receive the second SRS on the first SRS resource i2 through the first beam j2.

[0160] It should be understood that the first SRS resource set may include three or more first SRS resources, each of which may be associated with a different first beam, respectively. The process of transmitting SRS on the first SRS resources through different first beams is similar to the above process. The specific process can be found in the relevant description above, and will not be repeated here.

[0161] It should be noted that the communication method provided in the present application can be applied to scenarios where SRS can be sent on SRS resources through beams, such as positioning, perception and other scenarios, and the embodiments of the present application are not limited to this.

[0162] For ease of understanding, the communication method provided in the embodiment of the present application is further described below using the positioning scenario as an example. It should be understood that the logic and terminology not explained below can be referred to the introduction of the above embodiment, and will not be repeated here.

Figure 6 As shown, the communication system may include a terminal device, a first network device, a second network device and a first device. A communication connection may be established between the terminal device, the first network device, the second network device and the first device to implement the communication method provided in the present application.

[0164] The first network device may be a serving base station participating in the positioning process, and the second network device may be a neighboring base station participating in the positioning process.

[0165] The first device can be used to initiate a positioning process and obtain relevant information such as the position, speed, acceleration, etc. of the terminal device, and return this information to the relevant device or network element, which can be a specific device, network element or functional entity. In other words, the second device is a device, network element or functional entity that can provide a positioning function for the terminal device. It should be understood that, among others, the network element may also be referred to as an entity, device, device or module, etc., and this application does not specifically limit this. In some possible implementations, the second device may be a location management function (LMF) network element in the 5G network architecture. It should be understood that in future communication systems, the second device may still be an LMF network element, or the second device may also be other network elements, or the second device may also have other names, and this application does not limit this. It should be understood that this application does not limit the specific type of the second device.

[0169] S702: The first device sends a positioning information request message to the first network device. Correspondingly, the first network device receives the positioning information request message.

[0170] Among them, the positioning information request message can be used to instruct the first network device to configure an SRS resource set for the terminal device.

[0171] Optionally, the first device may send a positioning information request message to the first network device via NR Positioning Protocol A (NRPPa). It should be noted that the embodiment of the present application does not specifically limit the communication protocol between the first device and the first network device.

[0178] Optionally, the first device may send the first configuration information to the first network device through NRPPa. The measurement request may be used to instruct the first network device to receive the SRS and measure the SRS.

[0179] S707: The first device sends first configuration information and a measurement request to the second network device. Correspondingly, the second network device receives the first configuration information and the measurement request.

[0180] Optionally, the first device may send the first configuration information to the second network device through NRPPa. It should be noted that the embodiment of the present application does not specifically limit the communication protocol between the first device and the second network device.

[0181] S708: The terminal device sends an SRS to the first network device. Correspondingly, the first network device receives the SRS.

[0188] exist Figure 7In the illustrated embodiment, the terminal device may report to the first network device its ability to support at least one SRS resource associated with multiple beams. Further, the first network device may configure at least one SRS resource that can be associated with multiple different beams for the terminal device based on the ability. This method can be used to transmit SRS on at least one SRS resource through multiple different beams, thereby avoiding the transmission of SRS on at least one SRS resource through the same beam, thereby improving the utilization rate of beam resources during the transmission of SRS and ensuring the transmission quality of SRS. In addition, since SRS can be transmitted through multiple different beams, the path for transmitting SRS during the positioning process can cover the direct path and the reflected path, which can eliminate the problem of low positioning accuracy caused by channel group delay error during the positioning process and improve the positioning accuracy.
