[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on June 26, 2023, with application number 202310760477.9 and invention name “Capability Information Reporting Method, Communication Method and Related Devices”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a capability information reporting method, a communication method, and related devices. Background Art

[0003] Non-terrestrial communications have unique advantages over terrestrial communications. For example, non-terrestrial communications can provide a wider coverage area. Non-terrestrial communications can be satellite communications or high-altitude platform communications. Non-terrestrial network equipment is not easily damaged by natural disasters or external forces. Non-terrestrial communications have been introduced into the fifth-generation (5G) communication system, which can provide communication services to areas such as oceans and forests that are not covered by terrestrial communication networks, and can also enhance the reliability of 5G communication systems. For example, it can ensure that users on airplanes, trains, and other transportation receive better communication services. It can provide more data transmission resources for 5G communications and increase the network speed. Therefore, supporting both terrestrial and non-terrestrial communications is an inevitable trend for future 5G communication systems, which has benefits in terms of wide coverage, reliability, multiple connections, and high throughput.

[0004] Currently, satellite communications have been introduced in the 3rd Generation Partnership Project (3GPP) standards as a communication scenario for 5G communications. In order to adapt to characteristics such as large delays and high mobility, the 3GPP standards have made corresponding enhancements to technologies such as timing, synchronization, and hybrid automatic repeat request (HARQ). Due to the long distance of satellite communications, in addition to traditional terminals, super-capable terminals need to be defined to improve communication quality. Super-capable terminals are not affected by size and power supply and can transmit higher output power. Therefore, the output power architecture defined for traditional terminals is no longer applicable to super-capable terminals.

[0005] Therefore, how network devices should communicate with super-capable terminals is a question worth considering.

[0006] Summary of the Invention

[0007] The present application provides a capability information reporting method, a communication method, and related devices, which are used for a terminal device to report N sets of capability information to a network device, thereby facilitating communication between the network device and the terminal device.

[0008] The first aspect of the present application provides a capability information reporting method, which is executed by a terminal device. The terminal device may be a device or apparatus with a chip, or a device or apparatus with an integrated circuit, or a chip, chip system, module, or control unit in the aforementioned device or apparatus, and this application does not limit this. It should be noted that in this application, when referring to a terminal device, it may refer to the terminal device itself, or to a chip, functional module or integrated circuit in the terminal device that completes the method provided by this application, and this application does not limit this. In the first aspect and its possible implementation methods, the method is described as being executed by a terminal device. The capability reporting method provided in this application includes:

[0009] The terminal device determines N sets of capability information; wherein each set of capability information in the N sets of capability information includes at least one of the following: rated output power, power backoff amount, antenna gain, output power density, type of antenna in the terminal device, maximum output power, minimum output power, or antenna capability level, and N is an integer greater than or equal to 1; the terminal device sends the N sets of capability information to the network device. This facilitates the network device to communicate with the terminal device based on the N sets of capability information. It can be seen from this that the terminal device can be a super-capable terminal, and the super-capable terminal can report the N sets of capability information it supports. This facilitates the network device to communicate with the super-capable terminal. For example, the network device implements power control and / or service type selection for the super-capable terminal based on the N sets of capability information.

[0010] The second aspect of the present application provides a communication method, which is performed by a network device. The network device may be a device or apparatus with a chip, or a device or apparatus with an integrated circuit, or a chip, chip system, module or control unit in the aforementioned device or apparatus, and the present application does not limit this. It should be noted that in the present application, when referring to a network device, it may refer to the network device itself, or to a chip, functional module or integrated circuit in the network device that completes the method provided in the present application, and the present application does not limit this. In the second aspect and its possible implementation methods, the method is described as being performed by a network device. The communication method provided in the present application includes:

[0011] The network device receives N sets of capability information from the terminal device; wherein each set of capability information in the N sets of capability information includes at least one of the following: rated output power, power backoff amount, antenna gain, output power density, type of antenna in the terminal device, maximum output power, minimum output power, or antenna capability level, and N is an integer greater than or equal to 1; the network device communicates with the terminal device based on the N sets of capability information. It can be seen that the terminal device can be a super-capable terminal, and the super-capable terminal can report the N sets of capability information it supports. This facilitates communication between the network device and the super-capable terminal. For example, the network device implements power control and / or service type selection for the super-capable terminal based on the N sets of capability information.

[0012] Based on the first aspect or the second aspect, in one possible implementation, the terminal device supports Nmax groups of capability information, where N is less than or equal to Nmax, and Nmax is an integer greater than or equal to 2. In this implementation, the terminal device may be a super-capable terminal, and the terminal device supports at least two or more groups of capability information.

[0013] Based on the first aspect or the second aspect, in one possible implementation, N sets of capability information include N indexes, each of the N indexes corresponding to a set of capability information in the N sets of capability information. In this implementation, the terminal device can indicate the N sets of capability information using the N indexes. This enables indicating the N sets of capability information to the network device. This reduces the signaling overhead generated by indicating the N sets of capability information.

[0014] Based on the first aspect or the second aspect, in one possible implementation, among N sets of capability information, different sets of capability information correspond to at least one different parameter; the at least one parameter includes at least one of the following: the modulation mode, modulation order, code rate, spectral efficiency, waveform, polarization mode, time-frequency resource location allocated to the terminal device, the communication scenario in which the terminal device is located, or the motion state of the terminal device. In this implementation, each set of capability information corresponds to at least one different parameter. This indicates the capability information supported by the terminal device under corresponding operating conditions. This facilitates communication between the network device and the terminal device based on the reported N sets of capability information.

[0015] Based on the first aspect or the second aspect, in a possible implementation, the maximum output power P of the terminal device CMAX，f，c The following conditions are met:

[0016] P CMAX_L，f，c ≤P CMAX，f，c ≤P CMAX_H，f，c

[0017] in, P CMAX_H，f，c=min(P EMAX，c , P MOP_High );P EMAX，c The upper limit of the output power of the terminal equipment configured for the network equipment, P EMAX，c The value of belongs to the interval [X, Y], X is P EMAX，c The minimum value of Y is P EMAX，c The maximum value of P MOP_Low is the minimum output power supported by the terminal equipment, P MOP_High is the maximum output power supported by the terminal device, The maximum power fallback value supported by the terminal device, P1 is equal to P MOP_High Or the maximum output power supported by the terminal type to which the terminal device belongs as specified for the network device.

[0018] This implementation specifies the maximum output power of the terminal device, thereby enabling the super-capable terminal to communicate with the network device using the corresponding output power.

[0019] Based on the first aspect or the second aspect, in a possible implementation, X is less than or equal to -30dB (decibel), and Y is greater than 33dB. In this implementation, the values ​​of X and Y are specified. EMAX，c The upper limit of the output power is higher than the upper limit of the output power configured by the network equipment for traditional terminal equipment.

[0020] Based on the first aspect or the second aspect, in a possible implementation, X = -30dB, Y = 64dB. It can be seen that for a super-capable terminal, P EMAX，c The upper limit of the output power is higher than the upper limit of the output power configured by the network equipment for traditional terminal devices. This enables the super-capable terminal to communicate with the network equipment using a higher output power.

[0021] Based on the first aspect or the second aspect, in a possible implementation, the minimum output power P of the terminal device CMIN，f，c The following conditions are met:

[0022] Among them, P2 is the rated output power of the terminal device without power fallback. The maximum power fallback value supported by the terminal device. This implementation specifies the minimum output power of the terminal device. This allows ultra-capable terminals to communicate with network devices using the corresponding output power.

[0023] Based on the first or second aspect, in one possible implementation, the value of P2 falls within the interval [a, b], where a is greater than 23dB and less than or equal to 31dB, and b is greater than 31dB. Therefore, for super-capable terminals, the upper limit of P2 is higher than the upper limit of the output power configured by the network device for traditional terminal devices. This enables super-capable terminals to communicate with network devices using higher output power.

[0024] Based on the first or second aspect, in one possible implementation, a = 29dB and b = 60dB. Thus, for super-capable terminals, the upper limit of P2 is higher than the upper limit of the output power configured by the network device for traditional terminal devices. This enables super-capable terminals to communicate with network devices using higher output power.

[0025] Based on the first or second aspect, in one possible implementation, the antenna type in the terminal device includes one or more of the following: a parabolic antenna, a phased array antenna, an omnidirectional antenna, a directional antenna, an active antenna, or a passive antenna.

[0065] The embodiments of the present application provide a capability information reporting method, a communication method, and related devices, which are used for a terminal device to report N sets of capability information to a network device, thereby facilitating communication between the network device and the terminal device.

[0066] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present application. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0067] In this application, "at least one" means one or more, and "more" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. Among them, A and B can be singular or plural. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can mean: a, b, c, ab, ac, bc, or abc. Among them, a, b, c can be single or plural.

[0068] The technical solution of the present application can be applied to a terrestrial network system, and can also be applied to a non-terrestrial network (NTN) system.

[0069] Terrestrial network systems may include cellular communication systems, Internet of Things (IoT) communication systems, Internet of Vehicles (IoV) communication systems, device-to-device (D2D) communication systems, and mobile communication systems. Mobile communication systems may include fourth-generation (4G) communication systems, worldwide interoperability for microwave access (WiMAX) communication systems, 5G communication systems, and future mobile communication systems. For example, a 4G communication system may be a long-term evolution (LTE) system, and a 5G communication system may be a new radio (NR) system.

[0070] Non-terrestrial network systems can include satellite communication systems and high altitude platform station (HAPS) communication systems. For example, integrated communication and navigation (IcaN) systems, global navigation satellite systems (GNSS), and ultra-dense low-orbit satellite communication systems. Satellite communication systems can be integrated with traditional mobile communication systems.

[0071] The following describes some possible communication scenarios to which this application is applicable, in conjunction with Figures 1 to 3. This application is still applicable to other communication scenarios, and the following examples do not limit this application.

[0072] Figure 1 is a schematic diagram of a communication system according to an embodiment of the present application. Referring to Figure 1 , in this communication system, a terminal device on the ground establishes a communication connection with a base station via a satellite, enabling the terminal device to access the network.

[0073] Base stations can be deployed on the ground. Satellites are connected to ground stations via wireless links, and base stations are connected to ground stations. Ground stations and base stations are connected to the core network via wired or wireless links. Satellites act as forwarding devices (i.e., they only have transparent forwarding capabilities), forwarding signaling and data between terminal devices and base stations. Base stations primarily provide wireless access services, dispatch wireless resources to connected terminal devices, and offer reliable wireless transmission protocols and data encryption protocols. Ground stations are responsible for forwarding signaling and data between terminal devices and base stations, as well as between terminal devices and the core network.

[0074] In the communications system shown in Figure 1, the core network provides services such as user access control, mobility management, session management, user security authentication, and billing. The core network includes multiple functional units, which can be specifically divided into control plane functional entities and data plane functional entities. For example, the control plane functional entities include the access and mobility management function (AMF) and the session management function (SMF). The AMF is responsible for user access management, security authentication, and mobility management. The data plane functional entities include the user plane function (UPF). The UPF is responsible for managing user plane data transmission, traffic statistics, and other functions.

[0075] Figure 2 is another schematic diagram of a communication system according to an embodiment of the present application. Referring to Figure 2, in this communication system, some or all of the base station's functions are deployed on a satellite. Terminal devices on the ground establish a communication connection with the base station, enabling the terminal devices to access the network. Signaling and data are exchanged between the base station and the terminal devices. The base station is connected to the core network via a ground station, which is then connected to the core network via wired or wireless connections.

[0076] In the communication system shown in Figure 2, the core network includes multiple functional units, which can be specifically divided into control plane functional entities and data plane functional entities. For example, the control plane functional entities include the AMF and SMF. The data plane functional entity includes the UPF. For an introduction to the functions of these functional entities, please refer to the relevant descriptions above and will not be repeated here.

[0077] Figure 3 is another schematic diagram of a communication system according to an embodiment of the present application. Referring to Figure 3 , the communication system shown in Figure 3 is similar to the communication system shown in Figure 2 . As shown in Figure 3 , the communication system includes base station 1, base station 2, terminal device 1, and terminal device 2. Base station 1 is deployed on a satellite, and base station 2 is deployed on a satellite. Base station 1 and base station 2 can be connected via an Xn interface, enabling signaling exchange and user data transmission between base stations 1 and 2.

[0078] In the communication systems shown in Figures 1 to 3, the terminal device and the base station can implement the technical solution of the present application to report N groups of capability information supported by the terminal device to the base station, thereby enabling communication between the base station and the terminal device.

[0079] The communication system to which this application applies includes terminal devices and network devices. If some of the functions of the network device are deployed on a satellite, the network device may also be referred to as a satellite. If the network device and the satellite are deployed separately, the satellite is used to forward signaling and data between the terminal device and the network device.

[0080] The following introduces some possible forms of terminal devices and network devices.

[0081] A terminal device can be a device that provides voice or data connectivity to a user. A terminal device is also known as user equipment (UE), a mobile station, a subscriber unit, a station, terminal equipment (TE), customer premise equipment (CPE), or a mobile terminal (MT). For example, a terminal device is a device that includes wireless communication capabilities (providing voice / data connectivity to a user). Examples include handheld devices with wireless connectivity, in-vehicle devices, and machine type communication (MTC) terminals.

[0082] Currently, terminal devices may include: mobile phones, cellular phones, tablet computers, laptop computers, personal digital assistants (PDAs), wireless modems, cordless phones, PDAs, mobile internet devices (MIDs), wireless local loop (WLL) stations, wearable devices, computing devices, virtual reality (VR) devices, augmented reality (AR) devices, Internet of Things (IoT) devices, wireless terminals in industrial control, wireless terminals in self-driving (e.g., drones, vehicles), wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, and wireless terminals in smart cities. Wireless terminals in smart cities, terminal devices and vehicles in intelligent transportation, household appliances in smart homes, power meters, voltage monitoring instruments, and environmental monitoring instruments in smart grids, video surveillance equipment and cash registers in intelligent security networks, and wireless terminals in smart homes. For example, wireless terminals in unmanned driving can be drones, helicopters, or airplanes. For example, wireless terminals in the Internet of Vehicles can be onboard equipment, complete vehicle equipment, onboard modules, vehicles, or ships. Wireless terminals in industrial control can be cameras, robots, or robotic arms. Wireless terminals in smart homes can be televisions, air conditioners, vacuum cleaners, speakers, or set-top boxes.

[0083] The terminal device can be a mobile or non-mobile terminal, or an airborne or handheld terminal. In this application, the terminal device is optionally not limited by factors such as size and power supply, and can transmit high power. The terminal device can have one or more antennas. When a terminal device has multiple antennas, different antennas within the multiple antennas may have different capabilities or different antenna gains. The antenna gain of the antennas in the terminal device can be greater than or equal to zero.

[0084] It should be noted that the terminal device can be a device or apparatus with a chip, or a device or apparatus with an integrated circuit, or a chip, chip system, module or control unit in the device or apparatus shown above, and this application does not limit it specifically. It should be noted that in this application, when referring to a terminal device, it can refer to the terminal device itself, or it can refer to a chip, functional module or integrated circuit in the terminal device that performs the method provided in this application, and this application does not limit it specifically.

[0085] Network equipment supports terminal device access and provides communication services for terminal devices. For example, network equipment can be ground-based equipment such as evolved node B (eNB) in 4G access technology communication systems, next-generation node B (gNB) in 5G access technology communication systems, transmission reception points (TRP), relay nodes (relay nodes), access points (AP), and gateways. For example, gateways enable communication between terminal devices and the core network. For example, ground stations. Network equipment can also be non-terrestrial equipment such as satellite base stations, satellite ground stations, or high-altitude base stations. Examples include devices such as hot air balloons that provide wireless access to terminal devices, low-, medium-, or high-orbit satellites, drones, aircraft, mobile switching centers, and equipment that performs base station functions in device-to-device (D2D), vehicle-to-everything (V2X), and machine-to-machine (M2M) communications.

[0086] It should be noted that the network device can be a device or apparatus with a chip, or a device or apparatus with an integrated circuit, or a chip, chip system, module or control unit in the aforementioned device or apparatus, and this application does not limit this. It should be noted that in this application, when referring to a network device, it can refer to the network device itself, or it can refer to a chip, functional module or integrated circuit in the network device that performs the method provided in this application, and this application does not limit this.

[0087] Non-terrestrial communications offer unique advantages over terrestrial communications. For example, they can provide wider coverage. Non-terrestrial communications can include satellite communications or communications from high-altitude platforms. Non-terrestrial network equipment is less susceptible to damage from natural disasters or external forces. The introduction of non-terrestrial communications into 5G communication systems can provide communication services to areas beyond the reach of terrestrial communication networks, such as oceans and forests. It can also enhance the reliability of 5G communication systems, for example, ensuring better communication services for airplanes, trains, and other transportation users. This provides more data transmission resources for 5G communications and increases network speeds. Therefore, supporting both terrestrial and non-terrestrial communications is an inevitable trend in future 5G communication systems, offering benefits such as wide coverage, reliability, multiple connections, and high throughput.

[0088] At present, satellite communication has been introduced in the 3GPP standard as a communication scenario for 5G communication. In order to adapt to the characteristics of large delay and high mobility, the 3GPP standard has made corresponding enhancements to timing, synchronization, HARQ and other technologies. Due to the long distance of satellite communication, in addition to traditional terminals, it is also necessary to define super-capable terminals to improve communication quality. Super-capable terminals are not affected by size and power supply and can transmit a larger output power. Therefore, the output power architecture of traditional terminals is no longer applicable to super-capable terminals. Therefore, how network equipment should communicate with super-capable terminals is a problem worth considering. Here, satellite communication is mainly used as an example to introduce the problem to be solved by this application. Of course, this application is also applicable to other non-terrestrial networks, and this application is not specifically limited.

[0089] Ultra-capable terminals typically refer to fixed ground-based terminals, vehicle-mounted mobile terminals, airborne terminals, or shipborne terminals. Ultra-capable terminals can operate in lower frequency bands. For example, the 5G protocol frequency range (FR1) is 410MHz to 7125MHz, and the FR2 range is 24250MHz to 52600MHz. FR1 is a lower frequency band than FR2.

[0090] This application provides a corresponding technical solution for a terminal device to report N sets of capability information to a network device, thereby facilitating communication between the network device and the terminal device. For example, if the terminal device is a super-capable terminal, communication between the network device and the super-capable terminal can be achieved.

[0091] The technical solution of this application is introduced below in conjunction with specific embodiments.

[0092] FIG4 is a schematic diagram of an embodiment of a capability information reporting method and a communication method according to an embodiment of the present application. Referring to FIG4 , the method includes:

[0093] 401. The terminal device determines N sets of capability information.

[0094] Each of the N sets of capability information includes at least one of the following: rated output power, power backoff, antenna gain, output power density, antenna type, maximum output power, minimum output power, or antenna capability level. N is an integer greater than or equal to 1. Optionally, the rated output power is equal to the output power density multiplied by the bandwidth of the terminal device.

[0095] In this application, optionally, the terminal device supports Nmax sets of capability information, where N is less than or equal to Nmax, and Nmax is an integer greater than or equal to 2. That is, the terminal device supports two or more sets of capability information.

[0096] It should be noted that the terminal device may only support one power backoff amount. Then, for this implementation, the terminal device supports a set of capability information, and the set of capability information includes the power backoff amount of the terminal device.

[0097] In this application, the terminal device is a super-capable terminal. The size and power supply of the terminal device are not limited. Therefore, compared with traditional terminals, the terminal device can support a higher transmission power. For example, the maximum output power supported by the terminal device without power fallback is greater than 31dB.

[0098] Optionally, among the N groups of capability information, at least one of the following parameters corresponding to different groups of capability information is different. The at least one parameter includes at least one of the following: a modulation mode, modulation order, code rate, spectrum efficiency, waveform, polarization mode, time-frequency resource location allocated to the terminal device, a communication scenario in which the terminal device is located, or a motion state of the terminal device.

[0099] Optionally, the modulation scheme includes quadrature phase shift keying (QPSK), binary phase shift keying (BPSK), 16 quadrature amplitude modulation (16QAM), 64QAM, or 256QAM.

[0100] Optionally, the waveform includes discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM) or cyclic prefix orthogonal frequency division multiplexing (CP-OFDM).

[0101] Optionally, the polarization mode includes horizontal polarization, vertical polarization, left-hand polarization, or right-hand polarization.

[0102] Optionally, the communication scenario includes a high-orbit satellite communication scenario or a non-high-orbit satellite communication scenario.

[0103] Optionally, the motion state includes a high-speed motion state or a low-speed motion state.

[0104] As can be seen above, each set of capability information can correspond to an operating condition, and the operating condition can include at least one of the at least one parameter shown above. Terminal devices support different capabilities under different operating conditions. For example, if a terminal device uses different modulation modes, the capability information supported by the terminal device will be different.

[0105] Optionally, the terminal device reports N sets of capability information supported by the terminal device in the communication scenario based on the terminal device's location. For example, the terminal device determines that it is in a high-orbit satellite communication scenario based on broadcast information sent by the network device. The terminal device can use an antenna with higher output power and stronger capabilities to communicate with the network device. Therefore, the terminal device can report the corresponding capability information, enabling the terminal device to communicate with the network device in this high-orbit satellite communication scenario.

[0106] Optionally, the terminal device reports N sets of capability information supported by the terminal device based on its motion state. For example, if the terminal device is in high-speed motion, it can use a higher output power and a more powerful antenna to communicate with the network device. Therefore, the terminal device reports relevant capability information such as the higher output power and the more powerful antenna. For another example, if the terminal device is in low-speed motion, it can use a lower output power and a standard antenna to communicate with the network device. Therefore, the terminal device reports relevant capability information such as the lower output power and the standard antenna.

[0107] Optionally, the type of antenna in the terminal device includes one or more of the following: a parabolic antenna, a phased array antenna, an omnidirectional antenna, a directional antenna, an active antenna, or a passive antenna.

[0108] Optionally, the antenna capability of the terminal device can be divided into one or more antenna capability levels. Each antenna capability level corresponds to an antenna gain, and different antenna capability levels can correspond to different antenna gains. For example, if the terminal device has only one type of antenna, the terminal device can have only one antenna capability level. For another example, if the terminal device includes multiple types of antennas, each type of antenna in the multiple types of antennas has a corresponding antenna gain. Each type of antenna in the multiple types of antennas corresponds to an antenna capability level. For example, under a certain working condition, the terminal device can select a corresponding antenna to communicate with the network device. The corresponding set of capability information under the working condition includes the antenna capability level corresponding to the antenna.

[0109] Optionally, each set of capability information also includes the scanning mode of the antenna, for example, mechanical scanning or electronic scanning.

[0110] It should be noted that, optionally, the above-mentioned N groups of capability information are part of or all of the group capability information supported by the terminal device.

[0111] Optionally, the antenna gain in each set of capability information in the N sets of capability information may be greater than or equal to 0.

[0112] The following describes some possible implementations of each set of capability information in the N sets of capability information.

[0113] Implementation method 1: Each set of capability information in N sets includes rated output power.

[0114] For example, a possible implementation of N groups of capability information is shown below in conjunction with Table 1.

[0115] Table 1

[0116] In Table 1, operating conditions include the modulation scheme and waveform used by the terminal device. As can be seen from Table 1, the rated output power of the terminal device varies for different operating conditions. That is, the terminal device supports different rated output powers for different modulation schemes and / or waveforms. For example, when a terminal device uses QPSK modulation and a DFT-s-OFDM waveform, it supports a rated output power of 1. Therefore, the first set of capability information for the terminal device includes a rated output power of 1. When using BPSK modulation and a DFT-s-OFDM waveform, it supports a rated output power of 2. Therefore, the second set of capability information for the terminal device includes a rated output power of 2. When using 16QAM modulation and a DFT-s-OFDM waveform, it supports a rated output power of 3. Therefore, the third set of capability information for the terminal device includes a rated output power of 3. When using 64QAM modulation and a DFT-s-OFDM waveform, it supports a rated output power of 4. Therefore, the fourth set of capability information for the terminal device includes a rated output power of 4. When a terminal device uses 256QAM modulation and a DFT-s-OFDM waveform, it supports a rated output power of 5. That is, the terminal device's fifth set of capability information includes a rated output power of 5. When a terminal device uses QPSK modulation and a CP-OFDM waveform, it supports a rated output power of 6. That is, the terminal device's sixth set of capability information includes a rated output power of 6. When a terminal device uses BPSK modulation and a CP-OFDM waveform, it supports a rated output power of 7. That is, the terminal device's seventh set of capability information includes a rated output power of 7. When a terminal device uses 16QAM modulation and a CP-OFDM waveform, it supports a rated output power of 8. That is, the terminal device's eighth set of capability information includes a rated output power of 8. When a terminal device uses 64QAM modulation and a CP-OFDM waveform, it supports a rated output power of 9. That is, the terminal device's ninth set of capability information includes a rated output power of 9. When a terminal device uses 256QAM modulation and a CP-OFDM waveform, it supports a rated output power of 10. That is, the tenth set of capability information for the terminal device includes a rated output power of 10. In Table 1, under ten operating conditions, the terminal device can determine ten sets of capability information, each set of capability information including the rated output power of the terminal device under that corresponding operating condition. The terminal device can report these ten sets of capability information to the network device.

[0117] Implementation method 2: Each set of capability information in N sets includes a power backoff amount.

[0118] For example, another possible implementation of N groups of capability information is shown below in conjunction with Table 2.

[0119] Table 2

[0120] In Table 2, the operating conditions include the modulation mode and waveform used by the terminal device. As can be seen from Table 2, the terminal device's power backoff amount varies for different operating conditions. That is, the terminal device supports different power backoff amounts for different modulation modes and / or different waveforms. For example, when the terminal device uses QPSK modulation and a DFT-s-OFDM waveform, the terminal device supports power backoff amount 1. That is, the terminal device's first set of capability information includes power backoff amount 1. When the terminal device uses BPSK modulation and a DFT-s-OFDM waveform, the terminal device supports power backoff amount 2. That is, the terminal device's second set of capability information includes power backoff amount 2. When the terminal device uses 16QAM modulation and a DFT-s-OFDM waveform, the terminal device supports power backoff amount 3. That is, the terminal device's third set of capability information includes power backoff amount 3. When the terminal device uses 64QAM modulation and a DFT-s-OFDM waveform, the terminal device supports power backoff amount 4. That is, the terminal device's fourth set of capability information includes power backoff amount 4. When a terminal device uses 256QAM modulation and a DFT-s-OFDM waveform, it supports power backoff of 5. That is, the terminal device's fifth set of capability information includes power backoff of 5. When a terminal device uses QPSK modulation and a CP-OFDM waveform, it supports power backoff of 6. That is, the terminal device's sixth set of capability information includes power backoff of 6. When a terminal device uses BPSK modulation and a CP-OFDM waveform, it supports power backoff of 7. That is, the terminal device's seventh set of capability information includes power backoff of 7. When a terminal device uses 16QAM modulation and a CP-OFDM waveform, it supports power backoff of 8. That is, the terminal device's eighth set of capability information includes power backoff of 8. When a terminal device uses 64QAM modulation and a CP-OFDM waveform, it supports power backoff of 9. That is, the terminal device's ninth set of capability information includes power backoff of 9. When using 256QAM modulation and a CP-OFDM waveform, the terminal device supports a power backoff amount of 10. That is, the tenth set of capability information for the terminal device includes a power backoff amount of 10. In Table 2, the terminal device can determine ten sets of capability information under ten operating conditions, each set of capability information including the power backoff amount for the terminal device under that corresponding operating condition. The terminal device can report these ten sets of capability information to the network device.

[0121] In this implementation method 2, optionally, each set of capability information in the N sets of capability information also includes the rated output power of the terminal device without power fallback. For example, the rated output power belongs to the interval [a, b]. Optionally, the units corresponding to a and b are dB. For example, a is greater than 23dB and less than or equal to 31dB, and b is greater than 31dB. For example, the rated output power belongs to the interval [29dB, 60dB].

[0122] It can be seen that each set of capability information includes the rated output power of the terminal device without power backoff and the power backoff amount of the terminal device under corresponding working conditions.

[0123] Implementation method 3: Each set of capability information in N sets includes maximum output power and minimum output power.

[0124] Another possible implementation of N groups of capability information is shown below in conjunction with Table 3.

[0125] Table 3

[0126] In Table 3, the operating conditions include the modulation mode and waveform used by the terminal device. As can be seen from Table 3, the maximum output power and minimum output power supported by the terminal device may be different for different operating conditions. That is, the maximum output power and minimum output power supported by the terminal device are different for different modulation modes and / or different waveforms. For example, when the terminal device uses the QPSK modulation mode and the DFT-s-OFDM waveform, the terminal device supports a maximum output power of 1 and a minimum output power of 1. That is, the first set of capability information of the terminal device includes a maximum output power of 1 and a minimum output power of 1.

That is, the fifth set of capability information for the terminal device includes a maximum output power of 5 and a minimum output power of 5.

[0127] When using QPSK modulation and the CP-OFDM waveform, the terminal device supports a maximum output power of 6 and a minimum output power of 6. That is, the terminal device's sixth set of capability information includes a maximum output power of 6 and a minimum output power of 6.

When using 256QAM modulation and the CP-OFDM waveform, the terminal device supports a maximum output power of 10 and a minimum output power of 10. That is, the tenth set of capability information of the terminal device includes a maximum output power of 10 and a minimum output power of 10.

[0128] In Table 3, under ten operating conditions, the terminal device can determine ten sets of capability information, each set of capability information including the maximum output power and minimum output power supported by the terminal device under the corresponding operating condition. Therefore, the terminal device can report ten sets of capability information to the network device.

[0129] Implementation method 4: Each set of capability information in N sets includes maximum output power and power fallback amount.

[0130] For example, another possible implementation of N groups of capability information is shown below in conjunction with Table 4.

[0131] Table 4

[0132] In Table 4, the operating conditions include the modulation mode and waveform used by the terminal device. As can be seen from Table 4, the maximum output power and power backoff amount supported by the terminal device may be different for different operating conditions. That is, for different modulation modes and / or different waveforms, the maximum output power and power backoff amount supported by the terminal device are different. For example, when the terminal device uses the QPSK modulation mode and the DFT-s-OFDM waveform, the terminal device supports a maximum output power of 1 and a power backoff amount of 1. That is, the first set of capability information of the terminal device includes the maximum output power of 1 and the power backoff amount of 1. When the terminal device uses the BPSK modulation mode and the DFT-s-OFDM waveform, the terminal device supports a maximum output power of 2 and a power backoff amount of 2.

That is, the tenth set of capability information of the terminal device includes a maximum output power of 10 and a power backoff amount of 10.

[0134] In Table 4, under ten operating conditions, the terminal device can determine ten sets of capability information. Each set of capability information includes the maximum output power and power fallback amount supported by the terminal device under the corresponding operating condition. The terminal device can report these ten sets of capability information to the network device.

[0135] Optionally, in the above implementation manners 1 to 3, each set of capability information further includes an antenna capability level or an antenna gain.

[0136] For example, as shown in Table 5, another possible implementation of N groups of capability information is shown.

[0137] Table 5

[0138] In Table 5, operating conditions include the modulation mode and waveform used by the terminal device. As can be seen from Table 5, the maximum output power, power backoff amount, and antenna capability level supported by the terminal device can vary depending on the operating conditions. Specifically, the maximum output power, power backoff amount, and antenna capability level supported by the terminal device vary depending on the modulation mode and / or waveform.

[0139] Optionally, N groups of capability information may be indicated by N indexes, where each index in the N indexes corresponds to a group of capability information in the N groups of capability information.

[0140] In one possible implementation, each of the N sets of capability information includes a maximum output power and a minimum output power supported by the terminal device. Each of the N sets of capability information corresponds to an operating condition, and the operating condition may include at least one of the at least one parameter shown above.

[0141] For example, the terminal device indicates N groups of capability information through N indexes, as shown in Table 6:

[0142] Table 6

[0143] Each index in Table 6 corresponds to a set of capability information, and each set of capability information includes the maximum output power and minimum output power supported by the terminal device under corresponding working conditions. The working conditions may include the modulation mode and waveform adopted by the terminal device. The capability information supported by the terminal device is different for different modulation modes and / or different waveforms. For example, as shown in Table 6, the maximum output power and minimum output power supported by the terminal device in different sets of capability information may be different. As shown in Table 6, index 1 indicates the first set of capability information, and the first set of capability information includes the maximum output power 1 and the minimum output power 1 supported by the terminal device. Index 2 indicates the second set of capability information, and the second set of capability information includes the maximum output power 2 and the minimum output power 2 supported by the terminal device. Index 3 indicates the third set of capability information, and the third set of capability information includes the maximum output power 3 and the minimum output power 3 supported by the terminal device. Index 4 indicates the fourth set of capability information, and the fourth set of capability information includes the maximum output power 4 and the minimum output power 4 supported by the terminal device. Index 5 indicates the fifth set of capability information, and the fifth set of capability information includes the maximum output power 5 and the minimum output power 5 supported by the terminal device. Index 6 indicates the sixth set of capability information, which includes the maximum output power 6 and the minimum output power 6 of the terminal device. The terminal device can report indexes 1 to 6 to the network device, thereby indicating the first to sixth sets of capability information supported by the terminal device.

[0144] In another possible implementation, each of the N sets of capability information includes a maximum output power and a power fallback amount supported by the terminal device. Each of the N sets of capability information corresponds to an operating condition, and the operating condition may include at least one of the at least one parameter shown above.

[0145] For example, the terminal device indicates N groups of capability information through N indexes, as shown in Table 7:

[0146] Table 7

[0147] Each index in Table 7 corresponds to a set of capability information, and each set of capability information includes the maximum output power and power backoff amount supported by the terminal device under corresponding working conditions. The working conditions may include the modulation mode and waveform adopted by the terminal device. The capability information supported by the terminal device is different for different modulation modes and / or different waveforms. For example, as shown in Table 7, the maximum output power and power backoff amount supported by the terminal device in different sets of capability information may be different. As shown in Table 7, index 1 indicates the first set of capability information, and the first set of capability information includes the maximum output power 1 and power backoff amount 1 supported by the terminal device. Index 2 indicates the second set of capability information, and the second set of capability information includes the maximum output power 2 and power backoff amount 2 supported by the terminal device. Index 3 indicates the third set of capability information, and the third set of capability information includes the maximum output power 3 and power backoff amount 3 supported by the terminal device. Index 4 indicates the fourth set of capability information, and the fourth set of capability information includes the maximum output power 4 and power backoff amount 4 of the terminal device. Index 5 indicates the fifth set of capability information, and the fifth set of capability information includes the maximum output power 5 and power backoff amount 5 of the terminal device. Index 6 indicates the sixth set of capability information, which includes the maximum output power 6 and power fallback amount 6 of the terminal device. The terminal device can report indexes 1 to 6 to the network device, thereby indicating the first to sixth sets of capability information supported by the terminal device.

[0148] Optionally, the N indexes can also be understood as N modulation and coding scheme (MCS) indexes, where each MCS index in the N MCS indexes corresponds to a working condition, or each MCS index indicates a modulation and coding strategy adopted by the terminal device. For example, the working condition or modulation and coding strategy includes the modulation mode, modulation order, waveform, code rate, and / or spectrum efficiency adopted by the terminal device. For example, the above Table 1 can be expressed as shown in Table 8:

[0149] Table 8

[0150] MCS index 1 may correspond to one working condition. For example, the working conditions corresponding to MCS index 1 include that the terminal device adopts QPSK modulation, the modulation order adopted by the terminal device is 4, and the terminal device adopts DFT-s-OFDM waveform. MCS index 2 may correspond to another working condition. For example, the working conditions corresponding to MCS index 2 include that the terminal device adopts BPSK modulation, the modulation order adopted by the terminal device is 2, and the terminal device adopts DFT-s-OFDM waveform. The same is true for other MCS indexes in Table 8, and they are not described one by one here. It can be seen from Table 8 that each group of MCS indexes indicates a group of capability information, and different MCS indexes indicate different groups of capability information. That is, for different working conditions, the maximum output power and minimum output power supported by the terminal device may be different. That is, for different modulation modes, different modulation orders and / or different waveforms, the maximum output power and minimum output power supported by the terminal device may be different.

[0151] Optionally, one set of capability information can be considered as a terminal capability level, and N sets of capability information can be understood as N terminal capability levels of the terminal device. Therefore, N indexes indicate N terminal capability levels, and each index in the N indexes indicates a corresponding terminal capability level.

[0152] For example, as shown in Table 9, index 1 indicates terminal capability level 1, index 2 indicates terminal capability level 2, index 3 indicates terminal capability level 3, index 4 indicates terminal capability level 4, index 5 indicates terminal capability level 4, and index 6 indicates terminal capability level 6. Each terminal capability level corresponds to a set of capability information. Each set of capability information includes the maximum output power and minimum output power supported by the terminal device. For example, terminal capability level 1 indicates a first set of capability information, and the first set of capability information includes a maximum output power of 1 and a minimum output power of 1 supported by the terminal device. Terminal capability level 2 indicates a second set of capability information, and the second set of capability information includes a maximum output power of 2 and a minimum output power of 2 supported by the terminal device. Terminal capability level 3 indicates a third set of capability information, and the third set of capability information includes a maximum output power of 3 and a minimum output power of 3 supported by the terminal device. Terminal capability level 4 indicates a fourth set of capability information, and the fourth set of capability information includes a maximum output power of 4 and a minimum output power of 4 supported by the terminal device. Terminal capability level 5 indicates a fifth set of capability information, and the fifth set of capability information includes a maximum output power of 5 and a minimum output power of 5 supported by the terminal device. Terminal capability level 6 indicates the sixth set of capability information, which includes a maximum output power of 6 and a minimum output power of 6 supported by the terminal device. The terminal device can report indexes 1 to 6 to the network device, thereby indicating the terminal capability levels 1 to 6 supported by the terminal device. This indicates the six sets of capability information supported by the terminal device.

[0153] Table 9

[0154] In Table 9, each set of capability information includes the maximum and minimum output powers supported by the terminal device under corresponding operating conditions. Operating conditions may include the modulation mode and waveform used by the terminal device. The capability information supported by the terminal device varies for different modulation modes and / or waveforms. For example, as shown in Table 9, the maximum and minimum output powers supported by the terminal device in different sets of capability information may vary.

[0155] For another example, as shown in Table 10, index 1 indicates terminal capability level 1, index 2 indicates terminal capability level 2, index 3 indicates terminal capability level 3, index 4 indicates terminal capability level 4, index 5 indicates terminal capability level 4, and index 6 indicates terminal capability level 6. Each terminal capability level corresponds to a set of capability information. Each set of capability information includes the maximum output power and power backoff amount supported by the terminal device. For example, terminal capability level 1 indicates a first set of capability information, and the first set of capability information includes a maximum output power of 1 and a power backoff amount of 1 supported by the terminal device. Terminal capability level 2 indicates a second set of capability information, and the second set of capability information includes a maximum output power of 2 and a power backoff amount of 2 supported by the terminal device. Terminal capability level 3 indicates a third set of capability information, and the third set of capability information includes a maximum output power of 3 and a power backoff amount of 3 supported by the terminal device. Terminal capability level 4 indicates a fourth set of capability information, and the fourth set of capability information includes a maximum output power of 4 and a power backoff amount of 4 supported by the terminal device. Terminal capability level 5 indicates a fifth set of capability information, and the fifth set of capability information includes a maximum output power of 5 and a power backoff amount of 5 supported by the terminal device. Terminal capability level 6 indicates the sixth set of capability information, which includes a maximum output power of 6 and a power backoff amount of 6 supported by the terminal device. The terminal device can report indexes 1 to 6 to the network device, thereby indicating the terminal capability levels 1 to 6 supported by the terminal device. This indicates the six sets of capability information supported by the terminal device.

[0156] Table 10

[0157] In Table 10, each set of capability information includes the maximum output power and power backoff amount supported by the terminal device under corresponding operating conditions. The operating conditions may include the modulation mode and waveform used by the terminal device. The capability information supported by the terminal device varies for different modulation modes and / or different waveforms. For example, as shown in Table 10, the maximum output power and power backoff amount supported by the terminal device in different sets of capability information may vary.

[0158] In this application, it is optional to stipulate that the maximum output power of the terminal device meets the following conditions:
