Communication method and communication device

[0001] This application claims priority to the Chinese patent application with application number 202410406969.2 filed with the State Intellectual Property Office of China on April 3, 2024, and priority to the Chinese patent application with the invention name “A Communication Method and Communication Device”, all 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 communication method and a communication device. Background Art

[0003] In mobile communication networks, the transmit power of terminal devices is a key factor in ensuring the uplink performance of a cell. The transmit power of terminal devices is primarily limited by the RF front-end device—the power amplifier (PA). The main function of the PA is to convert low-power signals into higher-power RF signals, thereby reducing signal attenuation between the transmitter and the receiver and ensuring that the receiver can receive sufficiently strong signals. However, the core semiconductor device of the PA is a transistor, which has nonlinear characteristics. The nonlinear interaction between the input signal and the PA generates harmonics and intermodulation distortion, which can lead to a decrease in signal quality and affect the effective transmission and reception of information. Secondly, due to the nonlinear effect, higher-order harmonics and intermodulation products are generated. These products may fall into adjacent channels, thereby causing electromagnetic interference to the adjacent channel signals, seriously affecting the effective utilization of spectrum resources.

[0004] To ensure in-band signal quality and mitigate out-of-band interference, the 3rd Generation Partnership Project (3GPP) radio frequency protocol defines multiple radio frequency (RF) metrics to standardize terminal device implementation, such as error vector magnitude (EVM), in-band emission (IBE), adjacent channel leakage ratio (ACLR), spectral emission mask (SEM), and spurious emissions. Because higher transmit power means more severe PA nonlinearity, the protocol allows for a certain maximum power reduction (MPR) as the terminal device's transmit power increases. This back-off parameter accounts for the fact that PA nonlinearity can become severe at high power levels, potentially failing to meet the defined RF metrics. The MPR is primarily related to factors such as different resource block (RB) allocation regions, different modulation schemes, and different waveforms. RB allocation regions can be divided into edge RB allocation regions, outer RB allocation regions, and inner RB allocation regions.

[0005] Terminal devices can increase power by reducing the implementation margin. However, this method only works within the inner RB allocation area of ​​discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM) and cannot support power-constrained cell edge or multi-RB services. Therefore, improving the reliability of transmit power boosting for terminal devices is an urgent problem to be solved. Summary of the Invention

[0006] The embodiments of the present application provide a communication method and a communication device to improve the reliability of transmission power enhancement of a terminal device.

[0007] In a first aspect, an embodiment of the present application provides a communication method, which can be executed by a terminal device, or by a module (such as a processor, chip, or chip system, etc.) applied to the terminal device, or by a logical node, logical module, or software that can implement all or part of the terminal device functions. The method may include: the terminal device sends capability information of the terminal device to a network device, and the capability information of the terminal device is used to indicate that the terminal device is capable of performing transmit power enhancement on a specific RB allocation area under a first condition; wherein the first condition includes: the terminal device does not need to meet the first RF indicator or the terminal device only needs to meet the second RF indicator, and the second RF indicator is a relaxed first RF indicator; and transmit power enhancement is performed within the specific RB allocation area under the first condition.

[0008] In the solution provided in the present application, the terminal device can send capability information to the network device, and the capability information is used to indicate that the terminal device is capable of performing transmission power enhancement on a specific RB allocation area under a first condition, so that the terminal device can perform transmission power enhancement on a specific RB allocation area under the first condition, and the first condition includes not needing to meet the first RF indicator or only needing to meet the second RF indicator. That is to say, in a specific RB allocation area, the terminal device can achieve transmission power enhancement under RF indicator conditions of different degrees of relaxation. By relaxing the RF indicator, there is no need to change the software and hardware. The terminal device only needs to judge and adjust the corresponding PA parameters of the specific RB allocation area (such as not needing to meet the first RF indicator or only needing to meet the second RF indicator) to achieve transmission power enhancement, thereby improving the reliability of the transmission power enhancement of the terminal device.

[0009] In one possible implementation, the RB starting position RB of a specific RB allocation area Start Meet the following conditions: RB Start <RB Start,Low +P2 or RB Start >RB Start,High +P3. Among them, RB Start,Low =max(1,floor(L CRB / 2)), RB Start,High =N RB –RB Start,Low –L CRB , L CRB <ceil(N RB / 2), P2, P3 and N RB Related, N RB Indicates the maximum number of RBs in the terminal device channel bandwidth, ceil is greater than or equal to N RBBy implementing this possible implementation, an RB allocation region suitable for power boosting under the first condition is defined, thereby ensuring that the terminal device performs power boosting in a specific RB allocation region under the first condition.

[0010] In one possible implementation, if the first condition includes that the terminal device only needs to meet the second RF indicator, different specific RB allocation areas correspond to different second RF indicators. By implementing this possible implementation, if the first condition is that only the second RF indicator needs to be met, since the specific RB allocation area is related to the RB starting position and the number of RBs, that is, different RB starting positions and / or different RB numbers can obtain different specific RB allocation areas, the second RF indicator can be different according to different specific RB allocation areas. Different specific RB allocation areas correspond to different second RF indicators, which can enable the terminal device to obtain different power benefits according to different RB allocation areas, which is more accurate.

[0011] In one possible implementation, performing transmit power boost within a specific RB allocation area under a first condition includes: receiving first indication information from a network device, the first indication information being used to instruct a terminal device to perform transmit power boost within the specific RB allocation area under the first condition; and performing transmit power boost within the specific RB allocation area under the first condition according to the first indication information. By implementing this possible implementation, the network device can configure / activate the terminal device to perform transmit power boost within the specific RB allocation area under the first condition through the indication information. Through policy configuration of the network device, the implementation of transmit power boost for the terminal device can be made more flexible.

[0012] In one possible implementation, the first indication information corresponds to a first numerical value, which is used to indicate that within a specific RB allocation area, the terminal device does not need to meet the first RF indicator while performing transmit power boost. By implementing this possible implementation, the network device indicates different first conditions to the terminal device (i.e., the first indication information corresponds to different numerical values) according to different application scenarios, thereby achieving different power benefits in different scenarios.

[0013] In one possible implementation, the first indication information corresponds to a second numerical value, indicating that within a specific RB allocation area, the terminal device only needs to meet the second RF indicator while performing transmit power boost. By implementing this possible implementation, the network device indicates different first conditions to the terminal device (i.e., the first indication information corresponds to different numerical values) based on different application scenarios, thereby achieving different power benefits in different scenarios.

[0014] In one possible embodiment, the method may further include: receiving third indication information from the network device, the third indication information being used to indicate the frequency domain resources for uplink transmission of the terminal device, the frequency domain resources for uplink transmission of the terminal device including the starting position of the RB for uplink transmission of the terminal device and the number of RBs for uplink transmission of the terminal device. By implementing this possible embodiment, the network device may configure the frequency domain resources for uplink transmission to the terminal device, so that the terminal device can perform uplink transmission on the configured frequency domain resources. Furthermore, in an embodiment of the present application, the terminal device may determine that the frequency domain resources for uplink transmission are within a specific RB allocation area based on the third indication information. If so, it may be possible to perform transmission power enhancement on the specific RB allocation area under the first condition, thereby improving the reliability of the transmission power enhancement of the terminal device.

[0015] In one possible embodiment, the method may further include: determining, based on the first indication information of the network device and the specific RB allocation area, that the frequency domain resources of the uplink transmission of the terminal device from the network device are within the specific RB allocation area. By implementing this possible embodiment, if the network device configures / activates the terminal device through the indication information to perform transmit power enhancement within the specific RB allocation area under the first condition, the terminal device may first determine, based on the first indication information and the specific RB allocation area, that the frequency domain resources of the uplink transmission are within the specific RB allocation area. If so, transmit power enhancement may be performed on the specific RB allocation area under the first condition, thereby improving the reliability of transmit power enhancement of the terminal device.

[0016] In one possible implementation, the method may further include: receiving second indication information from the network device, the second indication information being used to indicate that the terminal device needs to meet the first RF indicator and not perform transmit power boost within a specific RB allocation area. By implementing this possible implementation, the network device may further deconfigure / deactivate the terminal device through the indication information, i.e., instructing the terminal device to meet the first RF indicator and not perform transmit power boost within the specific RB allocation area.

[0017] In one possible implementation, the transmit power enhancement includes reducing the MPR by a first value or increasing the transmit power of the terminal device by a first parameter. By implementing this possible implementation, the transmit power enhancement can be achieved by reducing the MPR by a first value or increasing the transmit power of the terminal device by a first parameter, thereby making the implementation of the transmit power enhancement of the terminal device more flexible.

[0018] In one possible implementation, the first value or first parameter corresponding to the discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM) waveform is different from the first value or first parameter corresponding to the cyclic prefix orthogonal frequency division multiplexing (CP-OFDM) waveform; or the first values ​​or first parameters corresponding to different modulation modes are different. By implementing this possible implementation, for the first value of MPR reduction, the first values ​​corresponding to different modulation modes and different waveforms can be the same or different, and the implementation method is more flexible. Furthermore, the first values ​​corresponding to different modulation modes and different waveforms are different, which can make the first value different according to the modulation mode and waveform, so that the transmission power enhancement of the terminal device is more accurately implemented.

[0019] In a possible implementation manner, the first indication information or the second indication information is carried in an information element (IE), a radio resource control (RRC), or a media access control entity (MAC CE).

[0020] In one possible implementation, the RF indicators include one or more of the following: adjacent channel leakage ratio (ACLR), spectral emission mask (SEM), in-band emission (IBE), error vector magnitude (EVM), and spurious.

The method may include: the network device receives capability information from a terminal device, the capability information of the terminal device is used to indicate that the terminal device is capable of performing transmit power enhancement on a specific RB allocation area under a first condition; wherein the first condition includes: the terminal device does not need to meet the first RF indicator or the terminal device only needs to meet the second RF indicator, and the second RF indicator is a relaxed first RF indicator.

[0022] In the solution provided in the present application, the network device can receive capability information from the terminal device, and the capability information is used to indicate that the terminal device is capable of performing transmission power enhancement on a specific RB allocation area under a first condition, so that the terminal device can perform transmission power enhancement on a specific RB allocation area under the first condition, and the first condition includes not needing to meet the first RF indicator or only needing to meet the second RF indicator. That is to say, in a specific RB allocation area, the terminal device can achieve transmission power enhancement under RF indicator conditions of different degrees of relaxation. By relaxing the RF indicator, there is no need to change the software and hardware. The terminal device only needs to judge and adjust the corresponding PA parameters of the specific RB allocation area (such as not needing to meet the first RF indicator or only needing to meet the second RF indicator) to achieve transmission power enhancement, thereby improving the reliability of the transmission power enhancement of the terminal device.

[0066] To better understand the embodiments of the present application, the following first introduces the system architecture involved in the embodiments of the present application:

[0067] The embodiments of the present application can be applied to communication systems evolved after 5G, such as long-term evolution (LTE) systems, fifth-generation mobile communication (5G) systems, and sixth-generation mobile communication (6G) systems, as well as satellite communications and short-range wireless communication systems. The wireless communication systems mentioned in the embodiments of the present application include, but are not limited to, the three major application scenarios of 5G / 6G mobile communication systems: enhanced mobile broadband (eMBB), ultra-reliable low latency communication (URLLC), and massive machine type communication (mMTC), long-range Internet of Things (LoRa) systems, or Internet of Vehicles systems. It should be understood that the embodiments of the present application can also be adapted to systems that comply with IEEE 802.11 system standards, such as 802.11bf, 802.11a / b / g, 802.11n, 802.11ac, 802.11ax, or their next generations, such as 802.11be, Wi-Fi 7 or EHT, or even next-generation standard systems, such as Wi-Fi 8, UHR, Wi-Fi AI and other 802.11 series protocols wireless local area network systems, or wireless personal area network systems based on ultra-wideband UWB, etc., and can also be applied to wireless local area network (WLAN) scenarios. Alternatively, the embodiments of the present application can also be applied to wireless local area network systems such as the Internet of Things (IoT) network or the Vehicle to X (V2X) network. A wireless communication system may include one or more network devices and one or more terminal devices.

[0068] The following explanation uses the system architecture shown in Figure 1 as an example. As shown in Figure 1, communication system 1000 includes a radio access network (RAN) 100, a core network (CN) 200, and the Internet 300. RAN 100 includes at least one network device (e.g., 110a and 110b in Figure 1, collectively referred to as 110) and at least one terminal device (e.g., 120a-120j in Figure 1, collectively referred to as 120). RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 1). Terminal device 120 is wirelessly connected to network device 110. Network device 110 is wirelessly or wiredly connected to core network 200. The core network devices in core network 200 and network device 110 in RAN 100 can be separate physical devices, or they can be a single physical device that integrates core network logical functions and radio access network logical functions.

[0069] It should be noted that RAN 100 can be a cellular system related to the 3rd Generation Partnership Project (3GPP), for example, a 4G or 5G mobile communication system, or an evolved system after 5G (for example, a 6G mobile communication system). RAN 100 can also be an open access network (open RAN, O-RAN or ORAN), a cloud radio access network (CRAN), etc. RAN 100 can also be a communication system that is a fusion of two or more of the above systems. It should be stated that the number of network devices and terminal devices in Figure 1 is only for illustration and should not be regarded as a specific limitation of this application. The terminal devices and network devices involved in the system architecture are described in detail below.

[0070] 1. Terminal Equipment

[0071] Terminal devices can also be called user equipment (UE), mobile station (MS), mobile terminal (MT), etc. They are devices used to provide voice or data connectivity to users, or they can be IoT devices. For example, terminal devices include handheld devices with wireless connectivity, in-vehicle devices, etc. Currently, terminal devices can include: mobile phones, tablet computers, laptop computers, PDAs, mobile internet devices (MIDs), wearable devices (such as smart watches, smart bracelets, pedometers, etc.), vehicle-mounted devices (such as cars, bicycles, electric vehicles, airplanes, ships, trains, high-speed trains, etc.), satellite terminals, virtual reality (VR) devices, augmented reality (AR) devices, smart point-of-sale (POS) machines, customer-premises equipment (CPE), wireless terminals in industrial control, smart home devices (such as refrigerators, televisions, air conditioners, electricity meters, etc.), intelligent robots, robotic arms, workshop equipment, wireless terminals in unmanned driving, wireless terminals in telemedicine, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, and flying devices (such as intelligent robots, hot air balloons, drones, airplanes). Terminal devices can also be other devices with terminal functions, for example, terminal devices can also be devices that function as terminals in D2D communication.

[0072] The embodiments of this application do not limit the device form factor of the terminal. The device used to implement the functions of the terminal device can be the terminal device; it can also be a device that supports the terminal device to implement the functions, such as a chip system. The device can be installed in the terminal device or used in conjunction with the terminal device. In the embodiments of this application, the chip system can be composed of chips or include chips and other discrete devices.

[0073] 2. Network Equipment

[0074] A network device is a node in a radio access network (RAN), and can also be referred to as an access network device or a RAN node (or device). A network device is used to help terminal devices achieve wireless access. The multiple network devices 110 in the communication system 1000 can be nodes of the same type or different types. In some scenarios, the roles of the network device 110 and the terminal device 120 are relative. For example, the network element 120i in Figure 1 can be a helicopter or a drone, which can be configured as a mobile base station. For terminal devices 120j that access the RAN 100 through the network element 120i, the network element 120i is a base station; but for the base station 110a, the network element 120i is a terminal device. The network device 110 and the terminal device 120 are sometimes referred to as communication devices. For example, the network elements 110a and 110b in Figure 1 can be understood as communication devices with base station functions, and the network elements 120a-120j can be understood as communication devices with terminal device functions.

[0075] In one possible scenario, a network device can be a base station, an evolved NodeB (eNodeB), a transmitting and receiving point (TRP), a transmitting point (TP), a next-generation NodeB (gNB), a next-generation base station in a sixth-generation (6G) mobile communication system, a base station in a future mobile communication system, a satellite, an integrated access and backhaul (IAB) node, a mobile switching center, or a network device in a non-terrestrial network (NTN) communication system, i.e., it can be deployed on a high-altitude platform or satellite. The network device can be a macro base station (such as 110a in Figure 1 ), a micro base station or an indoor station (such as 110b in Figure 1 ), a relay node or a donor node, or a wireless controller in a CRAN scenario. The network device can also be a device that functions as a base station in device-to-device (D2D) communication, Internet of Vehicles (IoV) communication, drone communication, or machine communication. Optionally, the network device can also be a server, a wearable device, a vehicle, or an onboard device. For example, a network device in vehicle to everything (V2X) technology may be a road side unit (RSU).

[0076] All or part of the functions of the network device in this application may also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform). The network device in this application may also be a logical node, logical module, or software that can implement all or part of the network device functions.

[0077] In another possible scenario, multiple network devices collaborate to assist the terminal device in achieving wireless access, and different network devices respectively implement part of the functions of the base station. For example, the network device 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 they 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). It can be understood that the network device can be a CU node, a DU node, or a device including a CU node and a DU node. In addition, the CU can be divided into a network device in the access network RAN, or the CU can be divided into a network device in the core network CN, which is not limited here.

[0078] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (Open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application uses CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0079] In the embodiments of the present application, the form of the network device is not limited. The device used to implement the function of the network device can be a network device; it can also be a device that can support the network device to implement the function, such as a chip system. The device can be installed in the network device or used in conjunction with the network device.

[0080] Further, please refer to Figure 2, which is a schematic diagram of a system architecture provided in an embodiment of the present application. As shown in Figure 2, the system architecture may include a terminal device and a network device. Among them, the terminal device may include a baseband, a digital-to-analog conversion, a power amplifier, an antenna, and an MPR control module. The terminal device can communicate with the network device through the antenna. For example, the terminal device can report capability information to the network device, and the network device can configure or activate the terminal device for power over-transmission. The terminal device can adjust the PA parameters through the MPR control module to achieve power enhancement. In an embodiment of the present application, the MPR module can configure a set of PA parameters including output signal power, PA voltage and other parameters according to the RB allocation area scheduled by the network device to control the PA output power to meet the uplink service requirements.

[0081] In order to facilitate understanding of the contents of this solution, some of the terms involved in the embodiments of this application are explained below to facilitate understanding by those skilled in the art. This part is only for ease of understanding and cannot be regarded as a specific limitation of this application.

[0082] 1. Power amplifier and nonlinear characteristics

[0083] In mobile communication networks, the transmit power of terminal devices is a key factor in ensuring cell uplink performance. Uplink performance refers to the ability of a terminal device to send data to network equipment, which affects the quality and stability of communications. Low transmit power can lead to unstable data transmission, degraded call quality, or even disconnected connections. Furthermore, the transmit power of terminal devices also affects the layout of network equipment.

[0084] The maximum transmit power of a terminal device is primarily limited by the RF front-end component—the power amplifier (PA). The PA's primary function is to convert low-power signals into higher-power RF signals, thereby reducing signal attenuation between the transmitter and receiver and ensuring the receiver can receive sufficiently strong signals. The PA's core semiconductor device is a transistor, which has nonlinear characteristics. Specifically, the PA can be mathematically modeled, as follows: Wherein x(t) and y(t) represent the time domain signals of the input and output of the PA respectively, n represents the model order, and a represents the coefficient corresponding to each order. Please refer to Figure 3, which is a schematic diagram of the amplitude curve of the input and output time domain signals provided by an embodiment of the present application. As shown in Figure 3, it can be seen that compression occurs at high power due to the presence of high orders, that is, nonlinear effects. Phenomena such as harmonics and intermodulation distortion generated by the nonlinear interaction between the input signal and the PA will lead to a decrease in signal quality, thereby affecting the effective transmission and reception of information and reducing the overall performance of the communication system. Secondly, due to the nonlinear effect, rich high-order harmonics and intermodulation products will be generated. These products may fall into adjacent channels, thereby forming electromagnetic interference to the adjacent channel signals, seriously affecting the effective utilization of spectrum resources.

[0085] Harmonic distortion occurs when an ideal pure sine wave signal passes through a PA. In addition to the original frequency, the output signal contains additional components at frequencies that are integer multiples of the fundamental frequency. These additional components are called harmonics. For example, if the input signal is at frequency f0, higher-order harmonics such as 2f0, 3f0, and 4f0 may appear. Intermodulation distortion occurs when multiple signals of different frequencies pass through the PA simultaneously. Nonlinear effects cause new frequency components to appear. These new frequencies are not any single frequency contained in the original signal, but rather the sum and difference frequencies between the original frequencies. For example, if the input signal has two frequencies, f1 and f2, intermodulation distortion may produce intermodulation products such as 2f1-f2 and 2f2-f1.

[0086] 2. Power limited indicator

[0087] To ensure in-band signal quality and suppress out-of-band interference, the 3GPP radio frequency protocol defines multiple RF metrics to standardize terminal device implementation, such as EVM, IBE, ACLR, SEM, and spurious emissions. Please refer to Figure 4, which is a schematic diagram of the frequency domain positions corresponding to various RF metrics, provided in an embodiment of the present application. As shown in Figure 4, EVM is a quantitative parameter used to assess the degree of difference between the actual received modulated signal and the ideal modulated signal. Specifically, in digital modulation communications, such as quadrature phase shift keying (QPSK) and quadrature amplitude modulation (QAM), each data symbol corresponds to a point on the constellation diagram. The error vector is the vector difference between the actual received signal and the ideal position it should theoretically be at at a specific sampling moment. This vector difference includes both amplitude and phase errors. When a terminal device transmits a signal, it should only send a valid modulated signal within the specified frequency range. However, in actual operation, due to factors such as PA nonlinearity, emissions may also occur in other in-band regions outside the valid signal. This part is IBE. IBE must remain within certain regulatory limits to prevent interference to other users within the same user equipment channel bandwidth (UE channel bandwidth) and ensure that terminal devices can communicate correctly and efficiently within the allocated spectrum resources. ACLR refers to the ratio of the average leakage power generated in adjacent channels outside the UE CHBW to the transmit power on the UE CHBW. SEM refers to the maximum allowable leakage power in adjacent channels outside the UE CHBW. Both ACLR and SEM are designed to ensure that the transmitter does not cause excessive interference to other adjacent channels during operation. The difference between the two is that ACLR measures the average power in adjacent channels, while SEM measures the absolute power in adjacent channels. Spurious emissions indicate emissions outside the UE CHBW and are used to measure interference at frequencies farther away from the UE CHBW.

[0088] Since higher transmit power means more severe PA nonlinearity, as the transmit power of the terminal device increases, one of the above-mentioned RF indicators will inevitably become the primary limiting factor. Please refer to Figure 5, which is a schematic diagram of the primary limited RF indicator corresponding to a CP-OFDM waveform QPSK modulation method provided in an embodiment of the present application. As shown in Figure 5, under a 50MHz bandwidth, the horizontal axis is the starting position of the RB in the UE CHBW, and the vertical axis is the number of RBs in the UE CHBW, that is, each two-dimensional coordinate in the figure corresponds to an RB allocation area including the RB starting position and the number of RBs. It can be seen from the figure that different RB allocation areas correspond to different primary limited RF indicators.

[0089] 3. Power parameters

[0090] According to different terminal equipment types and frequency band restrictions, the TR38.101-1 protocol defines four power levels (PC), namely PC1 (31dBm), PC1.5 (29dBm), PC2 (26dBm) and PC3 (23dBm). The maximum transmit power of the terminal equipment is P CMAX_f,c , as shown below: P CMAX_L,f,c ≤P CMAX_f,c ≤P CMAX_H,f,c

[0091] Among them, P CMAX_L,f,c and P CMAX_H,f,c Represents P CMAX_f,c The upper and lower limits, P EMAX,c Indicates the maximum transmit power of the network device configured as a terminal device, P PowerClass Indicates the PC capability reported by the terminal device to the network device, ΔP PowerClass Indicates the power increase allowed when allocating regions to internal RBs, ΔP PowerClass Terminal devices are allowed to reduce their PC in certain circumstances, such as from PC2 to PC3. MPR, ΔMPR, A-MPR (additional maximum power back-off), and P-MPR represent the corresponding power back-off in different situations. These back-off parameters take into account the severe PA nonlinearity at high power, which cannot meet the defined RF specifications. MPR can be related to different RB allocation areas, different modulation methods, and different waveforms. The MPR specified in the protocol can be shown in Table 1 below (Table 1 uses the MPR of PC3 as an example). ΔMPR allows for further back-off due to the excessive operating bandwidth. Because the radiation indicators in some sensitive areas are set very low, A-MPR allows for additional power back-off. Human radiation exposure is a regional regulation, and P-MPR is the power back-off to ensure that human radiation indicators do not exceed the standard.

[0092] Table 1 MPR of PC3

[0093] As shown in Figure 5, one of the factors affecting MPR is the RB allocation area, which can be divided into edge RB allocation area, external RB allocation area and internal RB allocation area according to the protocol. If the number of RBs is less than or equal to 2 RBs and the RB starting position is located at the upper and lower edges of the UE CHBW, it is an edge RB allocation area. The RB starting position and number of RBs in the internal RB allocation area must meet the following conditions: Start,Low ≤RB Start ≤RB Start,High L CRB≤ceil(N RB / 2)

[0094] Among them, RB Start Indicates the starting position of RB, L CRB Indicates the number of RBs, RB Start,Low =max(1,floor(L CRB / 2)), RB Start,High =N RB –RB Start,Low –L CRB . N RB Indicates the maximum number of RBs in UE CHBW, ceil means greater than or equal to N RB The minimum integer of / 2. If it does not belong to the inner RB allocation area or the edge RB allocation area, it belongs to the outer RB allocation area.

[0095] Generally, the MPR is defined according to the following basic rules: the MPR of lower-order modulation schemes must be less than or equal to that of higher-order modulation schemes, the MPR of the inner RB allocation area must be less than or equal to the MPR of the outer RB allocation area, and the MPR of the outer RB allocation area must be less than or equal to the MPR of the edge RB allocation area. Figure 5 also shows that the outer RB allocation area is primarily limited by the ALCR, but is also partially limited by the SEM; whereas the inner RB allocation area is primarily limited by the IBE.

[0096] First, in order to facilitate the understanding of the embodiments of the present application, the technical problems that the present application specifically aims to solve are further analyzed and proposed.

[0097] Currently, there are many technical solutions for increasing the transmit power of terminal devices. The following are two examples:

[0098] Solution 1: Technical solution for power enhancement in the internal RB allocation area

[0099] In 3GPP R18, as mentioned in the power parameter introduction of the above technical terms, the maximum transmit power of the terminal device P CMAX_f,c Introducing a new parameter ΔP PowerBoost , the terminal device can increase the power when the DFT-S-OFDM waveform is in the internal RB allocation area by reporting the terminal device capability indication. PowerClass When it is PC2, ΔP PowerBoost Equal to 0.5dB, when P PowerClass When it is PC3, ΔP PowerBoost The protocol also defines an enhanced internal RB allocation area, where the RB starting position and the number of RBs must meet the following conditions: Start,Low +P1≤RB Start ≤RB Start,High –P1

[0100] Where P1=[min{12,ceil(2+N RB / 25)}],N RB Indicates the maximum number of RBs in the terminal device channel bandwidth, ceil is greater than or equal to N RB The smallest integer greater than / 2. Refer to Figure 6, which is a diagram of different RB allocation areas provided in an embodiment of the present application. As shown in Figure 6, the number of RBs in the DFT-S-OFDM waveform must be a multiple of 2, 3, or 5.

[0101] The specific interaction process between the terminal device and the network device can be as follows: If the terminal device reports the capability [powerBoostRel18], it means that the terminal device can increase the power by reducing the implementation margin: In the enhanced internal RB allocation area, the power increases by ΔP PowerBoost At the same time, the MPR is 0dB; when it is in the internal RB allocation area and not in the enhanced internal RB allocation area, the power increases by ΔP PowerBoost At the same time, MPR is equal to ΔP PowerBoosr If the terminal device reports the capability [powerBoostTSRel18], it means that the terminal device can improve the power by reducing the nonlinearity of the PA in some ways: In the internal RB allocation area, the power is increased by ΔP PowerBoost At the same time, the MPR is 0dB. The network device can configure the terminal device with radio resource control (RRC) signaling to indicate that the terminal device can increase power and enable ΔP PowerBoost parameter.

[0102] The disadvantages of this solution are: 1. Limited scope of application: It only applies to the inner RB allocation area of ​​the DFT-S-OFDM waveform and cannot support power-limited cell edge or multi-RB demand services; 2. The power enhancement method of solution 1 is to reduce the realization margin, which puts a certain pressure on the margin.

[0103] Solution 2: Technical solution for defining ACLR indicators

[0104] Please refer to Figure 7, which is a schematic diagram of an ACLR indicator provided in an embodiment of the present application. As shown in Figure 7, it can be seen that the ACLR indicator is defined as a relative value, and the interference level varies depending on the reference power PC. For example, for PC1.5 = 29dBm, the ACLR is -2dBm; for PC2 = 26dBm, the ACLR is -5dBm; and for PC3 = 23dBm, the ACLR is -7dBm.

[0105] The disadvantage of this second solution is that ACLR is an RF indicator that quantifies the adjacent channel interference level. The interference level should not increase with increasing transmit power, so the indicator definition is unreasonable.

[0106] The above technical defects mainly include the following aspects:

[0107] 1. How to implement power boosting in the outer RB allocation area.

[0108] 2. How to achieve power enhancement while ensuring margin-friendly terminal equipment.

[0109] 3. How to define the ACLR indicator more reasonably.

[0110] Therefore, the technical problems to be solved by this application may include the following:

[0111] 1. Define new RF (such as ACLR) indicators and specific RB allocation areas (enhanced external RB allocation areas); 2. Introduce new terminal device capability indications. Under the first condition, in a specific RB allocation area, the terminal device can perform power enhancement; 3. Network equipment configures or activates the terminal device to perform power enhancement in a specific RB allocation area under the first condition according to different application scenarios.

[0112] The present application proposes a communication method, in which a terminal device can report new capability information, and the capability information is used to indicate that the terminal device can perform transmission power enhancement on a specific RB allocation area without satisfying a first RF indicator or only satisfying a second RF indicator. The terminal device can perform transmission power enhancement on a specific RB allocation area in combination with the RF indicator, thereby supporting power-limited cell edges or multi-RB demand services, and further improving the reliability of the transmission power enhancement of the terminal device. The following embodiments will be described separately. In the various embodiments of the present application, unless otherwise specified and logically conflicting, the terms and / or descriptions between different embodiments are consistent and can be referenced to each other, and the technical features in different embodiments can be combined to form a new embodiment according to their inherent logical relationships.

[0113] The communication method provided by the embodiment of the present application is described below. It is understandable that the present application uses a network device and a terminal device as an example to illustrate the execution subject of the interactive schematic, but the present application does not limit the execution subject of the interactive schematic. For example, the method performed by the network device in the present application may also be performed by a module (such as a chip, a chip system, or a processor) applied to the network device, and may also be implemented by a logical node, a logical module or software that can realize all or part of the functions of the network device; the method performed by the terminal device in the present application may also be performed by a module (such as a chip, a chip system, or a processor) applied to the terminal device, and may also be implemented by a logical node, a logical module or software that can realize all or part of the functions of the terminal device.

[0114] Please refer to Figure 8, which is an interactive diagram of a communication method provided by an embodiment of the present application. As shown in Figure 8, the communication method may include at least the following steps.

[0115] S801: The terminal device sends capability information of the terminal device to the network device, where the capability information indicates that the terminal device can perform transmit power boosting in a specific RB allocation region under a first condition. Correspondingly, the network device receives the capability information from the terminal device.

[0116] The terminal device may report capability information to the network device, where the capability information is used to indicate whether the terminal device is capable of performing transmission power boost on a specific RB allocation region under a first condition (indicates whether UE supports transmission power boost by a specific RB allocation region under a first condition).

[0117] The first condition may include: the terminal device does not need to meet the first radio frequency RF indicator or the terminal device only needs to meet the second RF indicator, and the second RF indicator is a relaxed first RF indicator.

[0118] It can be understood that the value of the first RF indicator can be the value of the RF indicator specified in the existing protocol, the value of the second RF indicator can be a redefined value different from the RF indicator specified in the existing protocol, or the value of the second RF indicator can be a new RF indicator value obtained by modifying the value of the RF indicator specified in the existing protocol. The RF indicator may include one or more of the following: ACLR, SEM, IBE, EVM, and spurious, etc. Since the primary restricted RF indicator in the external RB allocation area is ACLR, in one possible implementation method, the RF indicator can be ACLR. The following takes the RF indicator as ACLR as an example to exemplify the first RF indicator (corresponding to the first ACLR) and the second RF indicator (corresponding to the second ACLR):

[0119] For example, Table 2 shows the values ​​of the ACLR indicator (ie, the first ACLR) defined in the existing protocol.

[0120] Table 2 First ACLR index requirements

[0121] As shown in Table 2, the ACLR index value corresponding to PC1 is 37 dB, the ACLR index value corresponding to PC1.5 is 31 dB, the ACLR index value corresponding to PC2 is 31 dB, and the ACLR index value corresponding to PC3 is 30 dB.

[0122] The second ACLR value can be implemented by modifying the first ACLR value to obtain a new ACLR value. For example, the first ACLR value can be subtracted by a certain value to obtain a new ACLR value. Table 3 shows the second ACLR value.

[0123] Table 3 Second ACLR index requirements

[0124] As shown in Table 3, the ACLR value corresponding to PC1 is 36dB, the ACLR value corresponding to PC1.5 is 28dB, the ACLR value corresponding to PC2 is 25dB, and the ACLR value corresponding to PC3 is 22dB. Compared to Table 2, for different PCs, the second ACLR value can be obtained by subtracting 1, 3, 6, and 8 from the first ACLR value, respectively.

[0125] Alternatively, the second ACLR value can be implemented by redefining a value that is different from the first ACLR indicator. The current definition of ACLR is the ratio of the transmit power on the UE's channel bandwidth (CHBW) to the average leakage power generated by adjacent channels outside the UE's CHBW. This is a relative value and an RF indicator that quantifies the level of adjacent channel interference. The interference level should not increase with increasing transmit power. Therefore, a unified ACLR indicator value can be defined for different PCs. This redefined ACLR is an absolute value that does not increase with increasing transmit power, making it more reasonable.

[0126] The second RF indicator is the relaxed first RF indicator. It can be understood that the RF indicator may include one or more of the following: ACLR, SEM, IBE, EVM, and spurious. For ACLR, the value of the second ACLR indicator may be the value of the first ACLR indicator minus a positive number. If the value of the second ACLR indicator is lower than the value of the first ACLR indicator, the second ACLR indicator is the relaxed first ACLR indicator. For SEM, the value of the second SEM indicator may be the value of the first SEM indicator plus a positive number. If the value of the second SEM indicator is higher than the value of the first SEM indicator, the second SEM indicator is the relaxed first SEM indicator. For IBE, the value of the second IBE indicator may be the value of the first IBE indicator plus a positive number. If the value of the second IBE indicator is higher than the value of the first IBE indicator, the second IBE indicator is the relaxed first IBE indicator. For EVM, the value of the second EVM indicator may be the value of the first EVM indicator plus a positive number. If the value of the second EVM indicator is higher than the value of the first EVM indicator, the second EVM indicator is the relaxed first EVM indicator. For spurious, the value of the second spurious indicator may be the value of the first spurious indicator plus a positive number. If the value of the second spurious indicator is higher than the value of the first spurious indicator, the second spurious indicator is the relaxed first spurious indicator. In other words, the second RF indicator is a relaxed version of the first RF indicator. This means that, compared to the first RF indicator, the second RF indicator has lower ACLR and higher IBE, SEM, and spurious values. For example, as shown in Figure 8A, compared to Figure 4, the SEM and IBE values ​​increase, as does the spurious value. That is, the indicators shown in Figure 4 are the first RF indicators, while the indicators shown in Figure 8A are the second RF indicators.

[0127] Optionally, the second RF indicator is a relaxed first RF indicator. This means that the frequency range of the second RF indicator is extended outward compared to the frequency range of the first RF indicator. For example, as shown in Figure 8B , compared to Figure 4 , the frequency range of the SEM indicator is shifted outward in both the left and right directions along the X-axis. Similarly, the frequency ranges of the IBE and spurious emissions are also shifted outward in both the left and right directions along the X-axis. That is, the indicators shown in Figure 4 are first RF indicators, while the indicators shown in Figure 8B are second RF indicators.

[0128] The specific RB allocation area may also be referred to as an enhanced outer RB allocation area. In the embodiment of the present application, the specific RB allocation area may be determined by the RB starting position and the number of RBs.

[0129] In one possible implementation, the RB starting position RB of a specific RB allocation area Start The following conditions are met:

[0130] RB Start <RB Start,Low +P2 or RB Start >RB Start,High +P3

[0131] Among them, RB Start,Low =max(1,floor(L CRB / 2)), RB Start,High =N RB –RB Start,Low –L CRB , L CRB <ceil(N RB / 2), P2, P3 and N RB Related, N RB Indicates the maximum number of RBs in the terminal device channel bandwidth, ceil is greater than or equal to N RB / 2. Among them, P2, P3 and N RB Related, for example, P2 = ceil(N RB / 5) or P2=ceil(N RB / 4), P3 and P2 can be the same or different, such as P3 = ceil(N RB / 5) or P3=ceil(N RB / 4). It should be noted that P2 and P3 in the above formula can also be replaced by other parameters, such as P4, P5 or M1, M2, etc., which are not listed here one by one and do not constitute a limitation on the scope of protection of the embodiments of the present application. For the values ​​of P2 and P3 in the above formula, the embodiments of the present application only illustrate ceil(N RB / 5) or ceil(N RB / 4), it is understandable that it can also be other parameters, such as ceil(N RB / 3) or ceil(N RB / 6) or others, which are not enumerated here one by one, and also do not constitute a limitation on the scope of protection of the embodiments of the present application.

[0132] The second possible implementation method is to configure the transmission bandwidth of a terminal device that supports [UE capability] and is configured with extended bandwidth, and its bandwidth is greater than the transmission bandwidth of the terminal device channel bandwidth, by setting N RB Replace with N' RB . N' RB =N RB_low +N RB +N RB_high

[0133] Among them, N RB_low and N RB_high They are represented by RRC IE [extendedRBlow] and [extendedRBhigh] respectively. Internal RB allocation is the combination of traditional internal RB allocation and RB allocation, which is the intersection of extended internal RB allocation and traditional external RB allocation. Edge RB allocation refers to the allocation of RBs in the virtual / extended bandwidth L. CRB ≤2 RBs are allocated at the lowest or highest edge. The extended bandwidth is only used for RF requirements and does not affect actual transmission.

[0134] In virtual / extended bandwidth, the traditional internal RB allocation meets the following conditions: RB Start,Low =max(1,floor(L CRB / 2))+N RB_low RB Start,High =N' RB –N RB_high –RB Start,Low –L CRB +N RB_low RB Start,Low ≤RB Start ≤RB Start,High L CRB ≤ceil(N RB / 2)

[0135] A third possible implementation method is for a terminal device that supports the UE capability [MPRreduction-singleCC], and if [extendedCBW-Low] and [extendedCBW-High] are respectively set to the specified terminal device channel bandwidth (for example, the UE channel bandwidth specified in Table 5.3.2-1 of protocol 38.101), then a specific RB allocation region may satisfy: N' RB =NRB_low +N RB +N RB_high

[0136] Among them, N RB_low and N RB_high It is the maximum number of RBs for a given channel bandwidth, given by IE [extendedCBW-Low] and [extendedCBW-High] and the defined subcarrier spacing (e.g. Table 5.3.2-1). Start,Low =max(1,floor(L CRB / 2))+N RB_low RB Start,High =N' RB –N RB_high –RB Start,Low –L CRB +N RB_low RB Start,Low ≤RB Start ≤RB Start,High L CRB ≤ceil(N RB / 2)

[0137] In summary, the second and third possible implementations are shown in FIG8C , which is a diagram of an RB allocation area provided in an embodiment of the present application. As shown in FIG8C , the horizontal axis may represent the RB starting position, the vertical axis may represent the number of RBs, and each area may correspond to the actual RB allocation area (actual RB allocation), the new inner RB allocation area (newinner RB allocation), the extended inner RB allocation area (extendedinner RB allocation), and the inner RB allocation area (inner RB allocation). The RB allocation area corresponding to the dotted line may represent the new inner RB allocation area.

[0138] In a fourth possible implementation, if the indication for [extendedCBW-Low] and [extendedCBW-High] is equal to half the bandwidth of the CBW, then for a terminal device that supports the UE capability [MPRreduction-singleCC], and if the network indicates the IE [extendedCBW-Low] and [extendedCBW-High], the external RB allocation applies the MPR requirement to the internal RB allocation. As shown in Figure 8D, the figure can represent the RB allocation when the network indicates both [extendedCBW-Low] and [extendedCBW-High]. The figure can correspond to the external RB allocation region (based on actual RB allocation), the internal RB allocation region (based on actual RB allocation), the internal RB allocation region (based on extended RB allocation), and the external RB allocation region (based on extended RB allocation), respectively. The solid line area 1 in the RB allocation area corresponding to the dotted line can represent the internal RB allocation (based on the actual RB allocation), and this allocation area obeys the MPR requirements of the original internal RB allocation. The remaining area except the solid line area 1 in the RB allocation area corresponding to the dotted line can represent the original external RB allocation (based on the actual RB allocation), but this allocation area obeys the MPR requirements of the original internal RB allocation.

[0139] If the network indicates only IE[extendedCBW-Low], then it is valid to apply the MPR requirement to the inner RB allocation if the outer RB allocation satisfies the following conditions: Start ≤RB Start,High

[0140] As shown in Figure 8E, the figure can indicate that the network only indicates the RB allocation of [extendedCBW-Low], wherein area 1 in the RB allocation area corresponding to the dotted line can represent the internal RB allocation (based on the actual RB allocation), and the allocation area obeys the MPR requirements of the original internal RB allocation. The area 2 in the RB allocation area corresponding to the dotted line can represent the external RB allocation (based on the actual RB allocation), and both allocation areas obey the MPR requirements of the original internal RB allocation.

[0141] If the network indicates only IE[extendedCBW-High], then it is valid to apply the MPR requirement to the inner RB allocation if the outer RB allocation satisfies the following conditions: Start,Low ≤RB Star

[0142] As shown in Figure 8F, the figure may indicate that the network only indicates the RB allocation of [extendedCBW-High], wherein area 1 in the RB allocation area corresponding to the dotted line may represent the internal RB allocation (based on the actual RB allocation), and the allocation area obeys the MPR requirements of the original internal RB allocation, and area 2 in the RB allocation area corresponding to the dotted line may represent the external RB allocation (based on the actual RB allocation), but the allocation area obeys the MPR requirements of the original internal RB allocation.

[0143] S802: The terminal device performs transmit power boosting within a specific RB allocation area under a first condition.

[0144] Furthermore, the network device may send third indication information to the terminal device, where the third indication information is used to indicate the frequency domain resources for uplink transmission of the terminal device, where the frequency domain resources for uplink transmission of the terminal device include the starting position of the RB for uplink transmission of the terminal device and the number of RBs for uplink transmission of the terminal device. The third indication information may be carried in an IE, RRC, or MAC CE. The third indication information and the above-mentioned first indication information may be carried in the same IE, RRC, or MAC CE, or may be carried in different IEs, RRCs, or MAC CEs, which is not limited in this embodiment of the present application.

[0145] For a terminal device to perform transmit power boosting within a specific RB allocation area under the first condition, specifically:

[0146] In a first possible implementation, the terminal device can enhance itself, that is, after reporting the capability information in step S801, it can determine by itself whether to perform transmission power enhancement within a specific RB allocation area under the first condition. After receiving the capability information of the terminal device, the network device can also learn that the terminal device performs transmission power enhancement within a specific RB allocation area under the first condition. Furthermore, after receiving the third indication information from the network device, the terminal device can determine whether the frequency domain resources of the uplink transmission of the terminal device from the network device are within the specific RB allocation area based on the specific RB allocation area. If so, it can be determined to perform transmission power enhancement within the specific RB allocation area under the first condition; if not, it cannot perform transmission power enhancement within the specific RB allocation area under the first condition.

[0147] In a second possible implementation, the network device may configure / activate the terminal device through indication information so that the terminal device performs transmit power enhancement within a specific RB allocation area under a first condition. For example, the network device may send a first indication message to the terminal device, and the first indication message is used to instruct the terminal device to perform transmit power enhancement within a specific RB allocation area under a first condition. The terminal device may perform transmit power enhancement within the specific RB allocation area under the first condition based on the first indication message. Furthermore, after receiving the third indication message from the network device, the terminal device may determine whether the frequency domain resources of the uplink transmission of the terminal device from the network device are within the specific RB allocation area based on the first indication message and the specific RB allocation area. If so, it may be determined that the transmit power enhancement is performed within the specific RB allocation area under the first condition; if not, the transmit power enhancement cannot be performed within the specific RB allocation area under the first condition.

[0148] For the second possible implementation method mentioned above, further, the network device can determine the value corresponding to the first indication information according to different application scenarios. For example, if there are no adjacent channels around the channel bandwidth of the terminal device or if there are adjacent channels around the channel bandwidth of the terminal device but they belong to the same application server (since the adjacent channels belong to the same application server, the interference effect of the adjacent channels can be eliminated through certain methods or scheduling processing), then the first indication information can correspond to a first value, which is used to indicate that within a specific RB allocation area, the terminal device does not need to meet the first RF indicator and perform transmission power enhancement at the same time. For another example, if there are adjacent channels around the channel bandwidth of the terminal device but they belong to different application servers (since the adjacent channels belong to different application servers, the interference effect of the adjacent channels cannot be eliminated, and the interference level can be guaranteed to be within a reasonable range), then the first indication information can correspond to a second value, which is used to indicate that within a specific RB allocation area, the terminal device only needs to meet the second RF indicator and perform transmission power enhancement at the same time. In this possible implementation method, the network device indicates different first conditions to the terminal device according to different application scenarios, so that different power benefits can be obtained in different scenarios.

[0149] The first indication information may be carried in an IE, RRC, or MAC CE. For example, if IE=1, it may indicate that if the uplink transmission frequency domain resources of the terminal device are within a specific RB allocation area, the terminal device does not need to meet the first RF indicator and perform transmission power enhancement at the same time; for example, if IE=2, it may indicate that if the uplink transmission frequency domain resources of the terminal device are within a specific RB allocation area, the terminal device only needs to meet the second RF indicator and perform transmission power enhancement at the same time.

[0150] Furthermore, different values ​​corresponding to IE may also correspond to different P2 and P3. For example, IE=0 may represent P2=ceil(N RB / 5), P3=ceil(N RB / 5), such as IE=1, P2=ceil(N RB / 4) and P3=ceil(N RB / 4), such as IE=2, P2=ceil(N RB / 5), P3=ceil(N RB / 4), IE=3, P2=ceil(N RB / 4), P3=ceil(N RB / 5). Different waveforms and modulation methods can be identified by the name of the IE. For example, if the IE is [powerboostCPOFDMQPSK] and is set to 1, it means that for CPOFDMQPSK, the terminal device can RB / 4) and P3=ceil(N RB / 4) Determine a specific RB allocation area.

[0151] If the first condition includes that the terminal device does not need to meet the first RF indicator, the network device can indicate through the first indication information (such as IE=0) that the terminal device does not need to meet the first RF indicator and perform transmission power enhancement in a specific RB allocation area. Different waveforms and different modulation methods can be determined by the name of the IE. For example, if the IE is [powerboostCPOFDMQPSK] and is set to 1, it can indicate that for CP-OFDM QPSK, the terminal device does not need to meet the first RF indicator in a specific RB allocation area and perform transmission power enhancement at the same time.

[0152] If the first condition includes that the terminal device only needs to meet the second RF indicator, different values ​​corresponding to the IE can also correspond to different second RF indicators, so that the terminal device can determine the second RF indicator according to the value of the IE, so as to achieve that only the second RF indicator needs to be met in a specific RB allocation area and the transmission power is enhanced. For example, IE=0 can indicate that the second RF indicator such as ACLR is 22dB, such as IE=1, it can indicate that the second RF indicator such as ACLR is 24dB, such as IE=2, it can indicate that the second RF indicator such as ACLR is 26dB, and such as IE=3, it can indicate that the second RF indicator such as ACLR is 28dB. Different waveforms and different modulation modes can be determined by the name of the IE. For example, if the IE is [powerboostCPOFDMQPSK] and is set to 1, it can indicate that for CP-OFDM QPSK, the terminal device only needs to meet the second RF indicator (such as ACLR is 24dB) in a specific RB allocation area and perform transmission power enhancement.

[0153] Furthermore, different specific RB allocation areas may correspond to different second RF indicators. Please refer to FIG9 , which is a schematic diagram of an RB allocation area provided in an embodiment of the present application. As shown in FIG9 , RB allocation areas of CP-OFDM QPSK and DFT-s-OFDM QPSK are respectively represented. For example, for the RB allocation area of ​​CP-OFDM QPSK / 16QAM: if IE=0, P2=ceil(N RB / 5), P3=ceil(N RB / 5), the second RF indicator corresponding to the specific RB allocation area determined by P2 and P3, such as ACLR is 22dB; if IE=1, P2=ceil(N RB / 4) and P3=ceil(N RB / 4), the second RF indicator corresponding to the specific RB allocation area determined by P2 and P3, such as ACLR is 24dB; if IE=2, P2=ceil(N RB / 5), P3=ceil(N RB / 4), the second RF indicator corresponding to the specific RB allocation area determined by P2 and P3, such as ACLR is 26dB; if IE=3, P2=ceil(N RB / 4), P3=ceil(N RB / 5), the second RF indicator corresponding to the specific RB allocation area determined by P2 and P3, such as ACLR is 28dB; for another example, for the RB allocation area of ​​DFT-s-OFDM QPSK / 16QAM: if IE=0, P2=ceil(N RB / 5), P3=ceil(N RB / 5), the second RF indicator corresponding to the specific RB allocation area determined by P2 and P3, such as ACLR is 22dB; if IE=1, P2=ceil(N RB / 4) and P3=ceil(N RB / 4), the second RF indicator corresponding to the specific RB allocation area determined by P2 and P3, such as ACLR is 24dB; if IE=2, P2=ceil(N RB / 5), P3=ceil(N RB / 4), the second RF indicator corresponding to the specific RB allocation area determined by P2 and P3, such as ACLR is 26dB; if IE=3, P2=ceil(N RB / 4), P3=ceil(N RB / 5), the second RF indicator corresponding to the specific RB allocation area determined by P2 and P3, such as ACLR, is 28dB. It can be seen that due to the difference between P2 and P3, the specific RB allocation areas determined based on P2 and P3 are also different, so different RB allocation areas can correspond to different second RF indicator values.

[0154] It should be noted that for the RB allocation area of ​​CP-OFDM QPSK / 16QAM and the RB allocation area of ​​DFT-s-OFDM QPSK / 16QAM, the terminal device can distinguish different waveforms and modulation modes by different IE names. For example, if the IE is [powerboostCPOFDMQPSK] and is set to 2, it can mean that for CP-OFDM QPSK, P2=ceil(N RB / 5), P3=ceil(N RB / 5), the terminal device only needs to meet the second RF indicator (such as ACLR of 26dB) in a specific RB allocation area and perform transmit power boost at the same time; for example, if the IE is [powerboostDFTSOFDMQPSK] and is set to 2, it can be said that for DFT-s-OFDM QPSK, P2=ceil(N RB / 5), P3=ceil(N RB / 5), the terminal device only needs to meet the second RF indicator (such as ACLR of 226B) in a specific RB allocation area and perform transmit power enhancement at the same time.

[0155] For the first possible implementation and the second possible implementation described above, further optionally, the network device may also deconfigure / deactivate the terminal device through indication information, such as the network device sending second indication information to the terminal device, the second indication information being used to indicate that the terminal device needs to meet the first RF indicator and not perform transmit power enhancement within a specific RB allocation area. Exemplarily, the second indication information may correspond to a third value (such as IE=0), which is used to indicate that the terminal device needs to meet the first RF indicator and not perform transmit power enhancement within a specific RB allocation area.

[0156] It should be noted that the above-mentioned second indication information can be carried in IE, RRC or MAC CE.

[0157] The above-mentioned transmission power enhancement can be understood as that the MPR of the terminal device is reduced by a first value or the transmission power of the terminal device is increased by a first parameter.

[0158] In a first possible implementation, the terminal device can achieve transmit power enhancement by reducing the MPR. For example, assuming that the maximum transmit power P of the terminal device is CMAX,f,c Satisfy: P CMAX_L,f,c ≤P CMAX,f,c ≤P CMAX_H,f,c

[0159] Among them, P CMAX_L,f,c and P CMAX_H,f,c Represents P CMAX_f,c The upper and lower limits, P EMAX,c Indicates the maximum transmit power of the network device configured as a terminal device, P PowerClass Indicates the PC capability reported by the terminal device to the network device, ΔP PowerClass1 Indicates the power increase allowed when allocating a region to a specific RB, ΔP PowerClass Terminal devices are allowed to reduce PC in certain situations, for example, from PC2 to PC3. MPR, ΔMPR, A-MPR (additional maximum power back-off), and P-MPR represent the corresponding power back-off in different situations. These back-off parameters take into account that PA nonlinearity is very serious at high power and cannot meet the first RF indicator or the second RF indicator. MPR can be related to different RB allocation areas, different modulation methods, and different waveforms. ΔMPR allows for further back-off due to excessive working bandwidth. Because the radiation indicators in some sensitive areas are set very small, A-MPR allows for additional power back-off. Human radiation is a regulation in various regions, and P-MPR can be the power back-off to ensure that the human radiation indicator does not exceed the standard.

[0160] The MPR in the embodiment of the present application can be reduced by a first value, and the first values ​​corresponding to different specific RB allocation areas, different modulation modes and different waveforms can be the same or different. Among them, the modulation mode may include binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), hexadecimal quadrature amplitude modulation (16-ary quadrature amplitude modulation, 16QAM), sixty-four-ary quadrature amplitude modulation (64-ary quadrature amplitude modulation, 64QAM), two hundred and fifty-six-hexadecimal quadrature amplitude modulation (256-ary quadrature amplitude modulation, 256QAM), etc. The waveform may include a DFT-s-OFDM waveform and a CP-OFDM waveform, etc. The implementation method of reducing the first value of the MPR in the embodiment of the present application can be to add a new note (note) on the basis of the MPR of the existing protocol, or to add a new column of corresponding values.

[0161] For example, Table 4 illustrates the case where a new note is added to the MPR of PC3.

[0162] Table 4 MPR of PC3

[0163] For example, Table 5 takes the MPR of PC3 as an example to add a new column of corresponding values.

[0164] Table 5 MPR of PC3

[0165] As shown in Table 5, for a specific RB allocation area, the MPR may be the MPR defined by the existing protocol reduced by the first value. For example, compared with the external RB allocation area: for a DFT-s-OFDM waveform and a modulation mode of Pi / 2BPSK, the MPR of the specific RB allocation area may be the MPR corresponding to the external RB allocation area reduced by 1, that is, ≤0.2; for a DFT-s-OFDM waveform and a modulation mode of Pi / 2BPSK wPi / 2BPSK For DMRS, the MPR of a specific RB allocation area may be the value of the MPR corresponding to the external RB allocation area reduced by 0.5 (the first value corresponding to different modulation modes is different), that is, 0; for a DFT-s-OFDM waveform and modulation modes of QPSK and 16QAM, the MPR of a specific RB allocation area may be the value of the MPR corresponding to the external RB allocation area reduced by 1 (the first value corresponding to different modulation modes is the same), that is, 0 and 1, respectively; for a DFT-s-OFDM waveform and modulation modes of 64QAM and 256QAM, the MPR of a specific RB allocation area may be the value of the MPR corresponding to the external RB allocation area reduced by 0, that is, 2.5 and 4.5, respectively; For the CP-OFDM waveform and the modulation mode is QPSK, the MPR of the specific RB allocation area can be the value of the MPR corresponding to the external RB allocation area reduced by 1.5 (the first value corresponding to different waveforms is different), that is, 1.5; for the CP-OFDM waveform and the modulation mode is 16QAM, the MPR of the specific RB allocation area can be the value of the MPR corresponding to the external RB allocation area reduced by 1, that is, 2; for the CP-OFDM waveform and the modulation mode is 64QAM and 256QAM, the MPR of the specific RB allocation area can be the value of the MPR corresponding to the external RB allocation area reduced by 0 (the first value corresponding to different waveforms is the same), that is, 3.5 and 6.5 respectively. It can be understood that the specific MPR values ​​corresponding to the specific RB allocation areas in Table 2 are only examples and can also be other values, which do not constitute a limitation on the scope of protection of the embodiments of the present application.

[0166] In a second possible implementation, the terminal device can enhance the transmission power by increasing the first parameter of the transmission power. For example, the maximum transmission power P of the terminal device mentioned above CMAX,f,c The power increase ΔP allowed when allocating a specific RB region to the specified RB is expressed in the formula PowerClass1. Furthermore, the first parameters corresponding to different specific RB allocation areas, different modulation modes and different waveforms may be the same or different. For example, the first parameters corresponding to the DFT-s-OFDM waveform and the CP-OFDM waveform are different, or the first parameters corresponding to different modulation modes are different. Further optionally, if the terminal device can achieve transmit power enhancement by increasing the transmit power by the first parameter, then for the RB allocation area that belongs to the external RB allocation area but not in the specific RB allocation area, the MPR can be increased by ΔP PowerClass1 value, and if A-MPR exists, ΔP can also be increased PowerClass1 This is because the terminal device enhances the transmit power by increasing the transmit power by the first parameter, and the transmit power corresponding to all RB allocation areas will be increased by the first parameter. For RB allocation areas that belong to the external RB allocation area but are not in the specific RB allocation area, on the basis of increasing the transmit power by the first parameter, the MPR can also increase the first parameter to eliminate the impact of the increase in transmit power by the first parameter. That is to say, for RB allocation areas that belong to the external RB allocation area but are not in the specific RB allocation area, the MPR can also increase the first parameter to eliminate the impact of the transmit power enhancement achieved by increasing the transmit power corresponding to the specific RB allocation area by the first parameter.

[0167] In combination with the above description, a possible implementation manner of the terminal device performing transmit power boosting within a specific RB allocation area under the first condition may be as follows:

[0168] In a possible implementation, for the first condition including that the terminal device does not need to meet the first RF indicator, the network device indicates to the terminal device IE [powerboostCPOFDMQPSK], which is set to 1. The terminal device can determine that the waveform is CP-OFDM and the modulation mode is QPSK according to the name of the IE. Since IE = 1, it can be determined according to P2 = ceil (N RB / 4) and P3=ceil(N RB / 4) and the frequency domain resources of the uplink transmission indicated by the network device (including the RB starting position and the number of RBs) to determine a specific RB allocation area, and then determine that within the specific RB allocation area, the terminal device does not need to meet the first RF indicator and perform transmit power enhancement at the same time. The transmit power enhancement can correspond to the MPR indicator being reduced by 1dB or the power being increased by ΔP PowerClass1 .

[0169] In a possible implementation, for the first condition including that the terminal device only needs to meet the second RF indicator, the network device indicates to the terminal device IE [powerboostDFTSOFDM16QAM], which is set to 2. The terminal device can determine that the waveform is DFT-s-OFDM and the modulation mode is 16QAM according to the name of the IE. Since IE = 2, it can be determined according to P2 = ceil (N RB / 5), P3=ceil(N RB / 4) and the frequency domain resources for uplink transmission indicated by the network device (including the RB starting position and the number of RBs) determine a specific RB allocation area, and then determine that within the specific RB allocation area, the terminal device only needs to meet the second RF indicator (such as ACLR of 26dB) and perform transmit power enhancement at the same time. The transmit power enhancement can correspond to a 0.5B reduction in the MPR indicator or a power increase of ΔP PowerClass1 .

[0170] It should be noted that some or all of the terminal devices within the cell may be allowed to perform transmission power enhancement on a specific RB allocation area under a first condition. Please refer to Figures 10 and 11, which are schematic diagrams of a scenario provided by an embodiment of the present application. As shown in Figure 10, the scheduling policy of the network device may be that all terminal devices with the above-mentioned capabilities within the cell can perform transmission power enhancement on a specific RB allocation area under a first condition. As shown in Figure 11, the scheduling policy of the network device may be that some terminal devices with the above-mentioned capabilities within the cell can perform transmission power enhancement on a specific RB allocation area under a first condition. For this implementation, the scheduling policy of the network device can be made more flexible.

[0171] It is understood that the various numbers used in the embodiments of this application are merely for ease of description and are not intended to limit the scope of the embodiments of this application. The order of the sequence numbers of the above-mentioned processes does not necessarily imply a specific order of execution; the order of execution of the processes should be determined by their functions and inherent logic.

[0172] In an embodiment of the present application, a terminal device can perform transmit power enhancement on a specific RB allocation area under a first condition, where the first condition includes not needing to meet a first RF indicator or only needing to meet a second RF indicator. That is to say, in a specific RB allocation area, the terminal device can achieve transmit power enhancement under RF indicator conditions of different degrees of relaxation. By relaxing the RF indicator, there is no need to change the software or hardware. The terminal device only needs to judge and adjust the corresponding PA parameters for the specific RB allocation area (such as not needing to meet the first RF indicator or only needing to meet the second RF indicator) to achieve transmit power enhancement, thereby improving the reliability of the transmit power enhancement of the terminal device.

[0173] Please refer to Figure 12, which is a schematic diagram of the power gain of a terminal device provided in an embodiment of the present application performing transmit power enhancement on a specific RB allocation area under a first condition. As shown in Figure 12, taking the RF indicator as the ACLR indicator as an example for schematic illustration, for CP-OFDM QPSK with 6dB ACLR relaxation, 95% of the distribution function (cumulative distribution function, CDF) can achieve a power enhancement of 1dB within a specific RB allocation area. For terminal devices at the edge of the cell, a power enhancement of 1dB can bring an uplink throughput gain of 10% to 30%. Similarly, for DFT-s-OFDM QPSK with 5dB ACLR relaxation, 85% of the CDF can achieve a power enhancement of 0.8dB within a specific RB allocation area.

[0174] In conjunction with the method embodiment shown in FIG8 , for a first possible implementation of a terminal device performing transmit power boost within a specific RB allocation area under a first condition, please refer to FIG13 , which is an interactive schematic diagram of another communication method provided in an embodiment of the present application. As shown in FIG13 , the communication method may include at least the following steps.

[0175] S1301: The terminal device sends capability information of the terminal device to the network device, where the capability information indicates that the terminal device can perform transmit power boosting in a specific RB allocation region under a first condition. Correspondingly, the network device receives the capability information from the terminal device.

[0176] It can be understood that step S1301 corresponds to step S801. For a detailed description, please refer to the above-mentioned S801 and will not be repeated here.

[0177] S1302: The network device sends third indication information to the terminal device, where the third indication information is used to indicate frequency domain resources for uplink transmission of the terminal device. Correspondingly, the terminal device receives the third indication information from the network device.

[0178] The frequency domain resources for uplink transmission of the terminal device include the starting position of the RB for uplink transmission of the terminal device and the number of RBs for uplink transmission of the terminal device. The third indication information may be carried in IE, RRC or MAC CE.

[0179] S1303: The terminal device determines whether the frequency domain resources of the uplink transmission of the terminal device are within a specific RB allocation area. If so, execute step S1304.

[0180] After the terminal device receives the third indication information from the network device, it can determine whether the frequency domain resources of the terminal device's uplink transmission are within the specific RB allocation area based on the third indication information and the specific RB allocation area. If so, step S1304 can be executed. If not, the transmission power cannot be enhanced within the specific RB allocation area under the first condition.

[0181] S1304: The terminal device performs transmit power enhancement within a specific RB allocation area under the first condition.

[0182] The terminal device determines that the frequency domain resources for the uplink transmission of the terminal device are within a specific RB allocation area, and thus can implement transmit power enhancement within the specific RB allocation area under the first condition. Since the terminal device has reported capability information to the network device, the capability information is used to indicate that the terminal device is capable of performing transmit power enhancement on the specific RB allocation area under the first condition, and therefore the network device can be informed that the terminal device has performed transmit power enhancement on the specific RB allocation area under the first condition.

[0183] It is understood that the various numerical numbers involved in the embodiments of the present application are merely for the convenience of description and are not intended to limit the scope of the embodiments of the present application. The order of execution of the above-mentioned processes does not necessarily indicate the order in which they are executed. The order in which the processes are executed should be determined by their functions and inherent logic. For example, step S1302 may be executed before step S1301, and this is not limited in the embodiments of the present application.

[0184] In an embodiment of the present application, the terminal device can achieve self-enhancement. After reporting the capability information, when it is determined that the frequency domain resources for uplink transmission are within a specific RB allocation area, the transmit power can be enhanced in the specific RB allocation area under a first condition. The terminal device can perform transmit power enhancement in a specific RB allocation area under a first condition, and the first condition includes not needing to meet the first RF indicator or only needing to meet the second RF indicator. That is to say, in a specific RB allocation area, the terminal device can achieve transmit power enhancement under RF indicator conditions of different degrees of relaxation. By relaxing the RF indicator, there is no need to change the software and hardware. The terminal device only needs to judge the specific RB allocation area and adjust the corresponding PA parameters (such as not needing to meet the first RF indicator or only needing to meet the second RF indicator) to achieve transmit power enhancement, thereby improving the reliability of the transmit power enhancement of the terminal device.

[0185] In conjunction with the method embodiment shown in FIG8 , for a second possible implementation of a terminal device performing transmit power boosting within a specific RB allocation area under the first condition, please refer to FIG14 , which is an interactive schematic diagram of another communication method provided in an embodiment of the present application. As shown in FIG14 , the communication method may include at least the following steps.

[0186] S1401: The terminal device sends capability information of the terminal device to the network device, where the capability information indicates that the terminal device can perform transmit power boosting in a specific RB allocation region under a first condition. Correspondingly, the network device receives the capability information from the terminal device.

[0187] It can be understood that step S1401 corresponds to step S801. For a detailed description, please refer to the above-mentioned S801 and will not be repeated here.

[0188] S1402: The network device sends first indication information to the terminal device, where the first indication information is used to instruct the terminal device to perform transmit power enhancement in a specific RB allocation area under a first condition.

[0189] After receiving the capability information from the terminal device, the network device may determine a value corresponding to the first indication information based on different application scenarios, and send the first indication information to the terminal device, instructing the terminal device to perform transmit power boost in a specific RB allocation area under the first condition. For a specific description, please refer to the description in S802 above and will not be repeated here.

[0190] S1403: The network device sends third indication information to the terminal device, where the third indication information is used to indicate frequency domain resources for uplink transmission of the terminal device. Correspondingly, the terminal device receives the third indication information from the network device.

[0191] The frequency domain resources for uplink transmission of the terminal device include the starting position of the RB for uplink transmission of the terminal device and the number of RBs for uplink transmission of the terminal device. The third indication information may be carried in IE, RRC or MAC CE.

[0192] S1404: The terminal device determines whether the frequency domain resources of the uplink transmission of the terminal device are within a specific RB allocation area. If so, execute step S1405.

[0193] After the terminal device receives the third indication information from the network device, it can determine whether the frequency domain resources of the terminal device's uplink transmission are within the specific RB allocation area based on the third indication information and the specific RB allocation area. If so, step S1405 can be executed according to the first indication information. If not, the transmission power cannot be enhanced within the specific RB allocation area under the first condition.

[0194] S1405: The terminal device performs transmit power boosting within a specific RB allocation area under the first condition.

[0195] The terminal device determines that the frequency domain resources of the terminal device's uplink transmission are within a specific RB allocation area, and therefore can implement transmission power enhancement within the specific RB allocation area under the first condition based on the first indication information.

[0196] S1406: The network device sends second instruction information to the terminal device, where the second instruction information is used to instruct the terminal device to meet the first RF indicator and not perform transmit power boost within a specific RB allocation area.

[0197] The network device can deconfigure / deactivate the terminal device through indication information, such as sending a second indication information to the terminal device, where the second indication information is used to indicate that the terminal device needs to meet the first RF indicator and not perform transmit power enhancement within a specific RB allocation area. Exemplarily, the second indication information can correspond to a third value (such as IE=0), which is used to indicate that the terminal device needs to meet the first RF indicator and not perform transmit power enhancement within a specific RB allocation area. This enables deconfiguration / deactivation of the terminal device.

[0198] It is understood that the various numerical numbers involved in the embodiments of the present application are only for the convenience of description and are not intended to limit the scope of the embodiments of the present application. The size of the sequence number of each process does not mean the order of execution. The execution order of each process should be determined by its function and internal logic. For example, step S1403 can be executed before step S1401 and step S1402, or step S1402 can be executed together with step S1403. This embodiment of the present application does not limit this.

[0199] In an embodiment of the present application, the network device can configure / activate the terminal device through indication information according to different scenarios, and the terminal device performs transmission power enhancement in a specific RB allocation area under a first condition. The terminal device can perform transmission power enhancement in a specific RB allocation area under a first condition, and the first condition includes that the first RF indicator does not need to be met or only the second RF indicator needs to be met. That is to say, in a specific RB allocation area, the terminal device can achieve transmission power enhancement under RF indicator conditions of different degrees of relaxation. By relaxing the RF indicator, there is no need to change the software and hardware. The terminal device only needs to judge and adjust the corresponding PA parameters of the specific RB allocation area (such as not needing to meet the first RF indicator or only needing to meet the second RF indicator) to achieve transmission power enhancement, thereby improving the reliability of the transmission power enhancement of the terminal device.
