Description

Resource configuration method and related apparatus

[0001] The present application claims priority to the Chinese patent application No. 202411029578.X, filed on July 29, 2024, and entitled "Resource configuration method and related apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, and in particular to a resource configuration method and related apparatus. BACKGROUND

[0003] In a communication system, when a terminal device transmits a signal to a network device, a radio frequency index needs to be met to ensure the transmission quality of the signal. Under the premise of meeting the radio frequency index, the terminal device can be allowed to have a certain degree of backoff in the transmission power of the terminal device, that is, the terminal device is allowed to transmit at a power less than the maximum transmission power declared. The upper limit of the allowed backoff value is referred to as maximum power reduction (MPR).

[0004] Currently, the starting point of the out-of-band (OOB) constraint interval can be translated to equivalently reduce the maximum power reduction. For example, the spectrum resource configured by the network device to the terminal device can include a configuration bandwidth and a translation distance of the starting point of the out-of-band radio frequency index constraint interval, wherein the configuration bandwidth includes the total number of schedulable resource blocks, the configuration bandwidth can be used for transmitting an uplink signal, the translated out-of-band radio frequency index constraint interval is still located on both sides of the configuration bandwidth, and when the distance between the starting point of the translated out-of-band radio frequency index constraint interval on one side and the edge of the configuration bandwidth on the same side is equal to half the length of the configuration bandwidth, any scheduling belonging to outer resource block allocation (outer RB allocation) within the configuration bandwidth can be equivalently regarded as inner resource block allocation (inner RB allocation) with respect to twice the configuration bandwidth (the length of the extended total bandwidth), so that a lower maximum power reduction upper limit is used.

[0005] However, when the maximum power reduction is reduced based on this method, the transmission performance of the communication system is affected. SUMMARY

[0006] The present application provides a resource configuration method and related apparatus, which is beneficial to improve the transmission performance of the communication system.

[0007] In a first aspect, a resource configuration method is provided. The method is applied in a terminal device. The method comprises: sending first information, the first information being used for indicating at least one first maximum power reduction (MPR), the at least one first MPR corresponding to at least one first interval one by one, each of the at least one first MPR being an MPR used by the terminal device for determining a maximum transmission power when transmitting a signal on a first frequency spectrum resource within a corresponding first interval and a configuration bandwidth, the at least one first interval being a minimum translation distance of a starting point of an out-of-band radio frequency index constraint interval supported by the terminal device under at least one configuration bandwidth; receiving second information, the second information being used for indicating one or more of the following information: a length of a target interval, or a radio frequency index used in the target interval, the length of the target interval or the radio frequency index used in the target interval corresponding to a second MPR, the target interval being a translation distance of a starting point of an out-of-band radio frequency index constraint interval configured by a network device for the terminal device; determining a maximum transmission power of a signal based on a target MPR, the target MPR being equal to the second MPR, the second MPR being one of the at least one first MPR, or the target MPR being a linear interpolation between the second MPR and a third MPR, the third MPR being an MPR used by the terminal device for determining a maximum transmission power when transmitting a signal on a second frequency spectrum resource within the configuration bandwidth.

[0008] In the method, the length of the target interval indicated by the network device can be less than or equal to the length of the first interval corresponding to the second MPR, and the terminal device needs to further satisfy the radio frequency index corresponding to the first interval when transmitting the signal. In this way, the network can flexibly control the frequency range of the radio frequency index constraint, which is conducive to reducing the bottom noise rise of the frequency spectrum outside the configuration bandwidth when the terminal device transmits the signal by using the maximum transmission power determined according to the second MPR, thereby improving the transmission performance of the communication system.

[0009] In addition, the terminal device can determine the target MPR based on the length of the target interval and / or the radio frequency index of the target interval sent by the network device, and the length of the target interval and / or the radio frequency index of the target interval sent by the network device can be determined based on the at least one first MPR reported by the terminal device. That is, the target MPR can be determined by the at least one first MPR reported by the terminal device, and the at least one first MPR can be determined by the terminal device based on its own capability. The target MPR used by the terminal device can be determined based on the capability of the terminal device, so that a more accurate MPR can be obtained under the condition of satisfying the radio frequency index, thereby improving the transmission performance of the communication system.

[0010] In some possible implementation, when the second information indicates the length of the target interval and the radio frequency index used in the target interval, the method further includes: determining the second MPR from the at least one first MPR based on the length of the target interval and the radio frequency index used in the target interval, the length of the target interval being equal to the length of the first interval corresponding to the second MPR, and the radio frequency index used in the target interval being the same as the radio frequency index used in the first interval corresponding to the second MPR; determining the target MPR based on the second MPR, the target MPR being equal to the second MPR.

[0011] For example, in combination with FIG. 8, it is assumed that the at least one first interval includes first interval 1 and first interval 2. Wherein, the length of the first interval 1 is 4.86 MHz, the radio frequency index used in the first interval 1 is an in-band emission (IBE) index, and the first MPR corresponding to the first interval 1 is 2 dB. The length of the first interval 2 is 9.54 MHz, the radio frequency index used in the first interval 2 is a relaxed IBE index, and the first MPR corresponding to the first interval 2 is 1.5 dB.

[0012] And it is assumed that the second information sent by the network device to the terminal device indicates that the length of the target interval is 4.86 MHz, and the radio frequency index used in the target interval is an IBE index.

[0013] In this example, the terminal device can determine the first interval 1 as the first interval corresponding to the second MPR (i.e., the second interval), and determine the target MPR as the first MPR corresponding to the first interval 1, i.e., determine the target MPR as 2 dB.

[0014] In this implementation, since the second MPR is obtained by the terminal device based on the first interval corresponding to the second MPR and the radio frequency index used in the first interval corresponding to the second MPR, and the target MPR is equal to the second MPR, the target MPR obtained based on the method is more accurate, thereby facilitating obtaining a more accurate maximum transmission power of the signal.

[0015] In some possible implementation, when the second information indicates the length of the target interval, the method further includes: determining the second MPR from the at least one first MPR based on the length of the target interval, the first interval corresponding to the second MPR being the one with the smallest length among one or more first intervals, and the one or more first intervals being the first intervals in the at least one first interval with lengths greater than the length of the target interval; determining the target MPR based on the second MPR, the target MPR being a linear interpolation between the second MPR and the third MPR.

[0016] As an example, in combination with FIG. 9, it is assumed that the at least one first interval includes the first interval 3 and the first interval 4. Among them, the length of the first interval 3 is 4.86 MHz, and the first MPR corresponding to the first interval 3 is 2 dB. The length of the first interval 4 is 9.54 MHz, and the first MPR corresponding to the first interval 4 is 1.5 dB.

[0017] In this example, it is assumed that the length of the target interval indicated in the second information sent by the network device to the terminal device is 4 MHz. Then the terminal device can determine that the lengths of the two first intervals are both greater than 4 MHz, and then determine the first interval 3 with the smallest length among the two first intervals as the first interval corresponding to the second MPR.

[0018] In this implementation manner, the target MPR can be equal to a linear interpolation between the second MPR and the third MPR.

[0019] As an example, the linear difference formula between the second MPR and the third MPR can satisfy the following formula:

[0020] Among them, Y represents the length of the target interval, X represents the length of the first interval corresponding to the second MPR (i.e., the second interval), S1 represents the second MPR, and S0 represents the third MPR.

[0021] In this implementation manner, since the length of the target interval can be smaller than the length of the second interval, the length of the target interval configured by the network device can be smaller, which is beneficial to improve the utilization rate of the spectrum resource, thereby being beneficial to improve the transmission performance of the communication system.

[0022] In some possible implementation manners, the first information is further used to indicate one or more of the following information: the length of each first interval in the at least one first interval, or the radio frequency index used in each first interval.

[0023] In this implementation manner, for any one first interval, the radio frequency index used in the first interval can be understood as the radio frequency index that needs to be met in the first interval when the terminal device sends a signal.

[0024] In this implementation, the first information sent by the terminal device to the network device further indicates the length of each interval and / or indicates the radio frequency index used in each first interval. The network device can select, based on the length of each interval and / or the radio frequency index used in each interval, the first interval with the highest priority (for example, the first interval with the minimum length, and / or the amplitude vector error under the modulation mode corresponding to the radio frequency index is the minimum, and / or the corresponding MPR is the minimum) as the second interval, which is beneficial to obtain the target interval with higher priority. In this way, when the terminal device performs signal transmission based on the target interval with higher priority, the transmission performance of the communication system can be improved.

[0025] In some possible implementation, the information used to indicate the length of each first interval includes a ratio between the length of each first interval and the length of the configuration bandwidth.

[0026] Optionally, the information used to indicate the length of each first interval can include a ratio between the length of each first interval and the length of the configuration bandwidth, so that the terminal device only needs to transmit the ratio between the length of each first interval and the length of the configuration bandwidth to the network device, without the need to transmit the specific value of the length of each first interval to the network device, which is beneficial to reduce the transmission overhead of the first information between the terminal device and the network device.

[0027] In some possible implementation, the radio frequency index used in each first interval includes an in-band emission (IBE) index.

[0028] In this implementation, the IBE index can be associated with an EVM index, and the IBE index can be different when the value of the EVM index is different.

[0029] Optionally, when the value of the EVM index is the EVM index value corresponding to the BPSK modulation mode, the value of the EVM index is larger, and in this case, the IBE index can also be referred to as a relaxed IBE index.

[0030] In this implementation, the radio frequency index used in each first interval includes the IBE index, and the terminal device needs to further satisfy the IBE index used in each first interval when transmitting signals based on the first frequency spectrum resource in each first interval and the configuration bandwidth, which is beneficial to reduce the interference of the noise floor of each first interval to other frequency spectrums, and thus is beneficial to improve the transmission performance of the communication system.

[0031] In some possible implementation, the out-of-band radio frequency index includes one or more of the following: adjacent channel leakage ratio (ACLR), spectrum emission mask (SEM), or spurious emission (SE).

[0032] In the implementation, the terminal device also needs to meet the out-of-band radio frequency indicators when transmitting signals, which is beneficial to avoid leaking too much energy to the out-of-band spectrum resources, thereby improving the transmission performance of the communication system.

[0033] In a second aspect, a resource configuration method and related apparatus are provided, which are applied to a network device. The method includes: receiving first information, the first information being used to indicate at least one first maximum power reduction (MPR), the at least one first MPR corresponding to at least one first interval one by one, each first MPR in the at least one first MPR being an MPR used by a terminal device to determine a maximum transmission power when transmitting signals on a first spectrum resource within a corresponding first interval and a configured bandwidth, the at least one first interval being a minimum translation distance of a starting point of an out-of-band radio frequency indicator constraint interval supported by the terminal device under at least one configured bandwidth; and sending second information, the second information being used to indicate one or more of the following information: a length of a target interval, or a radio frequency indicator used in the target interval, the length of the target interval or the radio frequency indicator used in the target interval corresponding to a second MPR, the target interval being a translation distance of a starting point of an out-of-band radio frequency indicator constraint interval configured by the network device for the terminal device, the second MPR being one of the at least one first MPR.

[0034] In some possible implementation, the first information is also used to indicate one or more of the following information: a length of each first interval in the at least one first interval, or a radio frequency indicator used in each first interval.

[0035] In some possible implementation, the method further includes: determining a second interval, the second interval being an interval with a minimum length in the at least one first interval, and / or a magnitude vector error under a modulation mode corresponding to a radio frequency indicator used in the second interval being a minimum one in the at least one first interval, and / or a first MPR corresponding to the second interval being a minimum MPR in the at least one first MPR, the first MPR corresponding to the second interval being the second MPR; determining the length of the target interval based on the length of the second interval, the length of the target interval being equal to the length of the second interval; determining the radio frequency indicator used in the target interval based on the radio frequency indicator used in the second interval, the radio frequency indicator used in the target interval being the same as the radio frequency indicator used in the second interval.

[0036] In some possible implementation manners, the method further includes: determining a second interval, the second interval being an interval with a minimum length in the at least one first interval, and / or an amplitude vector error in a modulation mode corresponding to a radio frequency index used in the second interval being a minimum amplitude vector error in the at least one first interval, and / or a first MPR corresponding to the second interval being a minimum MPR in the at least one first MPR, the first MPR corresponding to the second interval being the second MPR; determining a length of the target interval based on a length of the second interval, the length of the target interval being smaller than the length of the second interval.

[0037] In some possible implementation manners, the information used for indicating the length of each first interval includes a ratio between the length of each first interval and a length of a configuration bandwidth.

[0038] In some possible implementation manners, the radio frequency index used in each first interval includes an in-band emission (IBE) index.

[0039] In some possible implementation manners, the out-of-band radio frequency index includes one or more of: an adjacent channel leakage ratio (ACLR), a spectral emission mask (SEM), or a spurious emission (SE).

Optionally, the wireless access network device can be a satellite, a macro base station, a micro base station or an indoor station, a relay node or a donor node, a device providing wireless communication services for a user equipment, a wireless controller in a cloud radio access network (CRAN) scenario, a server, a relay station, a vehicle or a vehicle-mounted device, a wearable device, and a network device in future evolution networks, etc. For example, the wireless access network device in vehicle to everything (V2X) technology can be a road side unit (RSU).

[0094] In another possible scenario, multiple wireless access network devices cooperate to assist a terminal to implement wireless access, and different wireless access network devices respectively implement part of the functions of a base station. For example, the wireless access network device can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately arranged, or can be included in the same network element, such as a 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 wireless access network device can be a CU node, or 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 wireless access network device, or the CU can be divided into a network device in the core network device, which is not limited here.

[0095] The CU (or CU-CP and CU-UP), DU or RU can also have different names in different systems, but those skilled in the art can understand their meanings. For example, in an open-radio access network (O-RAN) system, the CU can also be referred to as an O-CU (open CU), the DU can also be referred to as an O-DU, the CU-CP can also be referred to as an O-CU-CP, the CU-UP can also be referred to as an O-CU-UP, and the RU can also be referred to as an O-RU. For the convenience of description, the CU, CU-CP, CU-UP, DU and RU are taken as examples for description in this application. Any one of the 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.

[0096] In the embodiments of this application, the form of the radio access network device is not limited, and the device for implementing the function of the radio access network device can be a radio access network device; or can be a device capable of supporting the radio access network device to implement the function, such as a chip system. The device can be installed in the radio access network device or used with the radio access network device. In the following, the radio access network device will be taken as a base station for illustration.

[0097] In this application, the terminal can also be referred to as a terminal device, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc., or a device used to provide voice or data connectivity to a user, which can also be an Internet of Things device. For example, the terminal device includes a handheld device with wireless connection function, a vehicle-mounted device, etc. At present, the terminal device can be: a mobile phone, a tablet computer, a notebook computer, a palm computer, a mobile internet device (MID), a wearable device (such as a smart watch, a smart bracelet, a pedometer, smart glasses, etc.), a vehicle-mounted device (such as a car, a bicycle, an electric vehicle, an airplane, a ship, a train, a high-speed rail, etc.), a satellite terminal, a virtual reality (VR) device, an augmented reality (AR) device, a smart point of sale (POS) machine, a customer-premises equipment (CPE), a light terminal device (light UE), a reduced capability user equipment (REDCAP UE), a wireless terminal in industrial control, a smart home device (such as a refrigerator, a television, an air conditioner, an electricity meter, etc.), a smart robot, a mechanical arm, a workshop device, a wireless terminal in unmanned driving, a wireless terminal in telemedicine, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, or a wireless terminal in a smart home, a flight device (such as a smart robot, a hot air balloon, a drone, an airplane), etc. The terminal device can also be a vehicle device, such as a whole vehicle device, a vehicle-mounted module, a vehicle-mounted chip, an on board unit (OBU), or a telematics box (T-BOX), etc. The terminal device can also be other devices with terminal functions, for example, the terminal device can also be a device that plays a terminal function in D2D communication.

[0098] In the embodiments of the present application, the device for implementing the function of the terminal can be a terminal, or a device capable of supporting the terminal to implement the function, such as a chip system, or a communication module, or a modem, etc., which can be installed in the terminal. In the embodiments of the present application, the chip system can be composed of a chip, or can include a chip and other discrete devices. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal.

[0099] In this application, the base station and the terminal can be fixed in position or mobile. The base station and the terminal can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface; and can also be deployed on aircraft, balloons and satellites in the air. Embodiments of the present application do not limit the application scenarios of the base station and the terminal.

[0100] The roles of the base station and the terminal can be relative, for example, the helicopter or the unmanned aerial vehicle 120c in FIG. 1 can be configured as a mobile base station, and for those terminals 120d that access the wireless access network 100 through 120c, the terminal 120c is a base station; but for the satellite 110a, 120c is a terminal, that is, 110a and 120c communicate through a wireless air interface protocol. Of course, 110a and 120c can also communicate through an interface protocol between base stations and base stations, and at this time, 120c is also a base station relative to 110a. Therefore, the base station and the terminal can be collectively referred to as a communication device, and 110a, 110b, 110c and 120a-120g in FIG. 1 can be referred to as communication devices with their respective corresponding functions, such as a communication device with a base station function or a communication device with a terminal function.

[0101] The base station and the terminal, the base station and the base station, and the terminal and the terminal can communicate through licensed spectrum, unlicensed spectrum, or both. The base station and the terminal, and the terminal and the terminal can communicate through a sub-6G frequency spectrum, or a frequency spectrum above 6G, or both. Embodiments of the present application do not limit the frequency spectrum resources used between the wireless access network device and the terminal.

[0102] In this communication system, the communication between the network device and the terminal device can also be represented in another form, as shown in FIG. 2, the terminal device includes a processor 101, a memory 102 and a transceiver 103, the transceiver 103 includes a transmitter 1031, a receiver 1032 and an antenna 1033. The network device includes a processor 201, a memory 202 and a transceiver 203, the transceiver 203 includes a transmitter 2031, a receiver 2032 and an antenna 2033. The receiver 1032 can be used to receive transmission control information through the antenna 1033, and the transmitter 1031 can be used to send transmission feedback information to the network device through the antenna 1033. The transmitter 2031 can be used to send transmission control information to the terminal device through the antenna 2033, and the receiver 2032 can be used to receive transmission feedback information sent by the terminal device through the antenna 2033.

[0103] Optionally, the network device in the present application can also be replaced by a chip in the network device. The terminal device in the present application can also be replaced by a chip in the terminal device. In other words, the network element structure diagram shown in FIG. 2 can also represent a chip structure diagram applicable to the present application. As shown in FIG. 2, the chip of the terminal device includes a processor 101, a memory 102, and a transceiver 103, and the transceiver 103 includes a transmitter 1031, a receiver 1032, and an antenna 1033. The chip of the network device includes a processor 201, a memory 202, and a transceiver 203, and the transceiver 203 includes a transmitter 2031, a receiver 2032, and an antenna 2033. The receiver 1032 can be configured to receive transmission control information through the antenna 1033, and the transmitter 1031 can be configured to send transmission feedback information to the network device through the antenna 1033. The transmitter 2031 can be configured to send transmission control information to the terminal device through the antenna 2033, and the receiver 2032 can be configured to receive transmission feedback information sent by the terminal device through the antenna 2033.

[0104] In the existing communication system, before the terminal device sends a signal to the network device, the transmission power of the signal needs to be determined. The transmission power of the signal can be less than or equal to the maximum transmission power, which can also be referred to as the ideal transmission power.

[0105] The maximum transmission power can be associated with the power class (PC) claimed by the terminal itself. At present, the protocol has specified the association between the maximum transmission power and the power class of different frequency bands. For example, for some frequency bands, the maximum transmission power corresponding to the power class 2 is 26 decibels milliwatts (dBm). That is, for these frequency bands, if the terminal claims that the power class it supports is PC2, it means that the maximum transmission power of the terminal device can be 26 dBm.

[0106] The terminal device can transmit a signal based on the spectrum resource pre-configured by the network device. As shown in FIG. 3, the spectrum resource configured by the network device to the terminal device can include a configured transmission bandwidth, which can include a plurality of resource blocks (RBs) that can be used to transmit a signal. In the embodiment of the present application, the configured transmission bandwidth can also be referred to as a configured bandwidth, or a full-scheduled resource block, which can be represented by N RB In this example, one box can represent one resource block.

[0107] The terminal device can select at least one RB from N RB to transmit a signal, and the at least one RB is the actually transmitted RB, which can be referred to as the transmission bandwidth. In this example, the shaded part represents the actually transmitted RB.

[0108] Optionally, the spectrum resource configured by the network device to the terminal device can further include a guard band, which can be located at both sides of the configuration bandwidth, and the length of the guard band at both sides of the configuration bandwidth can be different.

[0109] In the embodiments of the present application, the spectrum resource configured by the network device to the terminal device can be referred to as a channel bandwidth (CBW).

[0110] For ease of understanding, in subsequent embodiments, the spectrum resource configured by the network device to the terminal device is taken as an example without including a guard band. In the example shown in FIG. 3, when the spectrum resource configured by the network device to the terminal device does not include a guard band, the length of the channel bandwidth can be equal to the length of the configuration bandwidth.

[0111] Before transmitting a signal, the terminal device can first use a power amplifier (PA) to amplify the to-be-transmitted signal, and then transmit the signal carried in a target frequency range through a modulator and a filter. However, the modulator and the filter have a nonlinear characteristic, and when the signal passes through the modulator and the filter, a nonlinear signal will be generated, thereby affecting the transmission quality of the signal. In the embodiments of the present application, the nonlinear signal can also be referred to as a distortion signal.

[0112] The nonlinear signal includes a second-order / third-order inter-modulation signal and a harmonics signal.

[0113] The power of the nonlinear signal is associated with the power of the to-be-transmitted signal. For example, the greater the power of the to-be-transmitted signal emitted by the terminal device, the greater the power of the nonlinear signal will be.

[0114] In order to ensure the transmission quality of the signal, when the terminal device transmits a signal to the network device, a radio frequency index needs to be met to ensure the transmission quality of the signal.

[0115] The radio frequency indicators can include a transmit modulation quality indicator. The transmit modulation quality indicator can include various indicators, such as an error vector magnitude (EVM) within scheduled resources, in-band emissions (IBE) within non-scheduled resources, and out-of-band radio frequency indicators, etc. The out-of-band radio frequency indicators can include an adjacent channel leakage ratio (ACLR), a spectrum emission mask (SEM), spurious emissions (SE), etc.

[0116] In embodiments of the present application, the in-band can be understood as the bandwidth configured by the network device to the terminal device, and the out-of-band can be understood as other bandwidths other than the bandwidth configured by the network device to the terminal device. For example, in the example shown in FIG. 3, the in-band can include the configured bandwidth and the guard band.

[0117] In embodiments of the present application, the scheduled resources can be understood as the bandwidth actually used for signal transmission by the terminal device when transmitting signals to the network device. For example, in the example shown in FIG. 3, the shaded part can represent the bandwidth within the scheduled resources.

[0118] The EVM reflects the error of the measured signal and the reference signal. The measured signal can be the signal actually transmitted by the terminal device.

[0119] In some communication systems, the terminal device can use a quadrature amplitude modulation (QAM) modulation method to modulate the signal to be transmitted. In this case, the reference signal can be a QAM constellation diagram.

[0120] In existing protocols, it is specified that the uplink EVM under different modulation modes cannot exceed a certain ratio. The EVM specified in the protocol is shown in Table 1.

[0121] Table 1: EVM

[0122] The IBE within the non-scheduled resources can ensure that other RBs in the in-band except the scheduled resources cannot have too high energy leakage, and is used to ensure that the uplink transmission of the terminal device does not bring too high interference to the spectrum not allocated to the terminal device (i.e., the out-of-band spectrum).

[0123] In existing protocols, the definition of the IBE indicator is shown in Table 2.

[0124] Table 2: Definition of IBE indicator

[0125] where L CRB represents the actual transmitted bandwidth, EVM represents the EVM of the allocated RBs in different modulation modes specified in Table 1, Δ RB may represent the starting frequency offset between the allocated RBs and the measured unallocated RBs, Δ RB = 1 and Δ RB = -1 represent the first adjacent RBs outside the allocated RBs. represents the average of the 10 subframe transmission powers normalized (divided by the number of allocated RBs).

[0126] As shown in Table 2, the conventional IBE is composed of three parts, the first part is related to the size of the allocated bandwidth, the second part is related to the EVM corresponding to the modulation mode in the scheduled resource and the relative position of the RB, and the third part is related to the observed signal-to-noise ratio (normalized to each RB) in the frequency band, and the maximum value of the three is the real effective index.

[0127] The IBE index can also limit the ratio of the actual transmission power of the terminal device on the scheduled RBs to the measured value of the power on a certain unallocated RB.

[0128] ACLR reflects the ratio of the strength of the transmitted signal on the in-band spectrum resource to the energy leakage of the out-of-band spectrum resource. In the existing protocol, the measurement bandwidth of the ACLR index and the definition of the ACLR index can be as shown in Table 3 and Table 4.

[0129] Table 3: ACLR measurement bandwidth

[0130] Table 4: Definition of ACLR index

[0131] The measurement bandwidth is consistent with the configuration bandwidth, and different power levels can correspond to different ACLR indexes. The ACLR index restricts the size of the leaked energy in the spectrum extending N RB left and right outside the configuration bandwidth.

[0132] The SEM index defines a step-type template, which limits the energy radiation value that the terminal device cannot exceed in each measurement bandwidth in different frequency ranges.

[0133] In the existing protocol, the definition of the SEM index can be as shown in Table 5.

[0134] Table 5: Definition of SEM index

[0135] where BWChannel may represent the channel bandwidth, Δf OOB represents the translation distance of the start point of the out-of-band radio frequency index constraint interval.

[0136] Taking a 20MHz channel bandwidth as an example, the energy after integration of every 0.2MHz spectrum in 0-1MHz outside the bandwidth cannot exceed -13dBm; the energy after integration of every 1MHz spectrum in 1-5MHz outside the bandwidth cannot exceed -10dBm; the energy after integration of every 1MHz spectrum in 5-20MHz outside the bandwidth cannot exceed -13dBm; the energy after integration of every 1MHz spectrum in 20-25MHz outside the bandwidth cannot exceed -25dBm.

[0137] Spurious emission refers to non-desired radiation outside the bandwidth caused by harmonic radiation, parasitic radiation, intermodulation products, and frequency transfer products, etc. The out-of-band spurious emission index is to constrain the size of non-desired radiation outside the configured bandwidth by the terminal device.

[0138] In the existing communication system, the terminal device can be allowed to have a certain degree of backoff of the transmission power under the premise of meeting the radio frequency index, that is, the terminal device is allowed to transmit at a power less than the declared maximum transmission power. The upper limit of the allowed backoff can be referred to as MPR.

[0139] In the existing protocol, the definition of MPR can be as shown in Table 6.

[0140] Table 6: Definition of MPR

[0141] The MPR under the same modulation mode and waveform can be smaller for inner resource block allocation than for other resource block allocation. This is because the closer to the edge of the frequency band, the higher the risk of not meeting the SEM and ACLR indexes; the closer to the center of the frequency band, the lower the risk of not meeting the SEM and ACLR indexes, and the terminal only needs a smaller power backoff to meet the EVM and IBE indexes.

[0142] As an example, assuming that the channel bandwidth is 20MHz (or the configured bandwidth is 20MHz) and the subcarrier spacing is 15kHz, the division of inner resource block allocation, outer resource block allocation, and edge resource block allocation can be as shown in FIG. 4.

[0143] In this example, the slope of the demarcation line between the inner resource block allocation and the outer resource block allocation is 1 / 2. When the scheduled resource blocks are less than N RB half and are centrally distributed, the terminal can use a smaller MPR based on the inner resource block allocation.

[0144] Currently, the MPR can be equivalently reduced by translating the start point of the OOB constraint interval. For example, the network device can configure, in the spectrum resource configured for the terminal device, a translation distance of the start point of the out-of-band radio frequency index constraint interval in addition to the configured bandwidth, wherein the configured bandwidth includes the total number of schedulable resource blocks, the configured bandwidth can be used for transmitting the uplink signal, the translated out-of-band radio frequency index constraint interval is still located on both sides of the configured bandwidth, and when the distance between the start point of the translated out-of-band radio frequency index constraint interval on one side and the edge of the configured bandwidth on the same side is equal to half the length of the configured bandwidth, any scheduling of the outer layer resource block allocation within the configured bandwidth can be equivalently regarded as the inner layer resource block allocation with respect to the double configured bandwidth (the length of the extended total bandwidth), so that a lower MPR upper limit is used.

[0145] In combination with FIG. 4, the translated out-of-band radio frequency index constraint interval is still located on both sides of the configured bandwidth, and when the distance between the start point of the translated out-of-band radio frequency index constraint interval on one side and the edge of the configured bandwidth on the same side is equal to half the length of the configured bandwidth, the division of the inner layer resource block allocation, the outer layer resource block allocation and the edge resource block allocation can be as shown in FIG. 5.

[0146] However, when the maximum power backoff is reduced based on the method, the transmission performance of the communication system is affected.

[0147] It is found through research that the reason for the poor transmission performance of the communication system is that the translated out-of-band radio frequency index constraint interval is still located on both sides of the configured bandwidth, and when the distance between the start point of the translated out-of-band radio frequency index constraint interval on one side and the edge of the configured bandwidth on the same side is equal to half the length of the configured bandwidth, the translation distance of the start point of the out-of-band radio frequency index constraint interval is long, which causes the network device to need to configure a very long spectrum resource, and the utilization rate of the spectrum resource is low. In addition, there is noise in the translation distance of the start point of the out-of-band radio frequency index constraint interval, which can interfere with other bandwidths.

[0148] Therefore, the present application provides a technical solution to solve the problem of poor transmission performance of the communication system in the prior art.

[0149] In the technical solution of the present application, the terminal device can first report at least one first MPR to the network device, the network device sends the length of the target interval and / or the radio frequency index used in the target interval to the terminal device according to the at least one first MPR, and then the terminal device can determine the target MPR based on the length of the target interval and / or the radio frequency index used in the target interval, and determine the maximum transmission power of the signal based on the target MPR.

[0150] The at least one first MPR can correspond to the at least one first interval in a one-to-one manner, the at least one first interval is a minimum translation distance of a starting point of an out-of-band radio frequency index constraint interval supported by the terminal device under the at least one configuration bandwidth, and each of the at least one first MPR is an MPR used to determine a maximum transmission power when the terminal device transmits a signal on a frequency spectrum resource in the corresponding first interval and the configuration bandwidth.

[0151] The target interval is a translation distance of a starting point of an out-of-band radio frequency index constraint interval configured by the network device for the terminal device.

[0152] A length of the target interval or a radio frequency index used in the target interval corresponds to a second MPR, the target MPR can be equal to the second MPR, the second MPR is one of the at least one first MPR, or the target MPR is a linear interpolation between the second MPR and a third MPR, and the third MPR is an MPR used to determine a maximum transmission power when the terminal device transmits a signal on a second frequency spectrum resource in the configuration bandwidth.

[0153] In the technical solution, the length of the target interval indicated by the network device can be less than or equal to the length of the first interval corresponding to the second MPR, and the terminal device needs to further satisfy the radio frequency index corresponding to the first interval when transmitting a signal. In this way, the network can flexibly control the frequency range of the radio frequency index constraint, which is beneficial to reduce the bottom noise lifting of the frequency spectrum outside the configuration bandwidth when the terminal device transmits a signal by using the maximum transmission power determined according to the second MPR, thereby improving the transmission performance of the communication system.

[0154] In the technical solution, the terminal device can determine the target MPR based on the length of the target interval and / or the radio frequency index of the target interval sent by the network device, and the length of the target interval and / or the radio frequency index of the target interval sent by the network device can be determined based on the at least one first MPR reported by the terminal device. That is, the target MPR can be determined by the at least one first MPR reported by the terminal device, and the at least one first MPR can be determined by the terminal device based on its own capability. The target MPR used by the terminal device can be determined based on the capability of the terminal device, so that a more accurate MPR can be obtained under the condition of satisfying the radio frequency index, thereby improving the transmission performance of the communication system.

[0155] Next, the present application will be described in detail in combination with FIGS. 6 to 12.

[0156] FIG. 6 is a flowchart of a resource configuration method provided by an embodiment of the present application.

[0157] S601, the terminal device sends first information to the network device, the first information being used for indicating at least one first MPR, the at least one first MPR corresponding to at least one first interval in one-to-one manner, each first MPR in the at least one first MPR being an MPR used by the terminal device to determine a maximum transmission power when transmitting a signal on a first frequency spectrum resource within the corresponding first interval and the configuration bandwidth, and the at least one first interval being a minimum translation distance of a starting point of an out-of-band radio frequency index constraint interval supported by the terminal device under at least one configuration bandwidth. Correspondingly, the network device receives the first information.

[0158] In the method, the terminal device can be any one of the terminal devices in the communication system shown in FIG. 1. In the embodiments of the present application, the steps related to the terminal device can be executed by the terminal device, or can be executed by the apparatus in the terminal device, or can be executed by the logic module or software realizing all or part of the terminal device function, or can be executed by the apparatus capable of being used in matching with the terminal device. As an example, the steps related to the terminal device can be executed by the whole machine, component, part or communication chip of the terminal device. Optionally, when the steps related to the terminal device are executed by the communication chip of the terminal device, the steps of sending / receiving can be realized by the terminal device through the transmission of corresponding baseband information by the input / output (I / O) interface.

[0159] In the method, the network device can be any one of the network devices in the communication system shown in FIG. 1. In the embodiments of the present application, the steps related to the network device can be executed by the network device, or can be executed by the apparatus in the network device, or can be executed by the logic module or software realizing all or part of the network device function, or can be executed by the apparatus capable of being used in matching with the network device. As an example, the steps related to the network device can be executed by the whole machine, component, part or communication chip of the network device. Optionally, when the steps related to the network device are executed by the communication chip of the network device, the steps of sending / receiving can be realized by the network device through the transmission of corresponding baseband information by the I / O interface.

[0160] In the method, for any one configuration bandwidth, the minimum translation distance of the starting point of the out-of-band radio frequency index constraint interval supported under the configuration bandwidth can be referred to as the first interval supported under the configuration bandwidth. The first interval supported under the configuration bandwidth and the first frequency spectrum resource within the configuration bandwidth can be understood as: the first interval and all or part of the frequency spectrum resources in the frequency spectrum resources occupied by the configuration bandwidth.

[0161] The terminal device transmits the signal on the first frequency spectrum resource by transmitting the signal within the configuration bandwidth in the first frequency spectrum resource.

[0162] In the method, for any MPR, the MPR can be an interval value or a specific value. Optionally, when the MPR is a specific value, the MPR can be an allowed upper limit value.

[0163] The at least one first MPR can be determined by the terminal device based on its capability. As an example, for any configuration bandwidth, the terminal device can first determine the length of a first interval supported under the configuration bandwidth based on its capability, and then calculate the first MPR corresponding to the first interval based on the length of the first interval and / or a radio frequency index possibly used in the first interval.

[0164] In a possible implementation, the first interval can include intervals on both sides of the configuration bandwidth, and the length of the first interval can be equal to the total length of the intervals on both sides of the configuration bandwidth.

[0165] In the implementation, the lengths of the intervals on both sides of the configuration bandwidth can be different.

[0166] In another possible implementation, the first interval can include an interval on one side of the configuration bandwidth, and the length of the first interval can include the length of the interval on one side of the configuration bandwidth.

[0167] In the implementation, the lengths of the intervals on both sides of the configuration bandwidth can be the same. When the lengths of the intervals on both sides of the configuration bandwidth are the same, the total length of the intervals on both sides of the configuration bandwidth can be equal to twice the length of the first interval.

[0168] In the embodiments of the present application, for any first interval, the length of the first interval can be indicated by the number of resource blocks occupied by the first interval, or the length of the bandwidth occupied by the first interval, or the ratio of the length of the first interval to the length of the configuration bandwidth.

[0169] In the embodiments of the present application, for any first interval, the radio frequency index used in the first interval can be understood as a radio frequency index that needs to be met by the terminal device when transmitting a signal in the first interval.

[0170] For any first interval, the radio frequency index possibly used in the first interval can include an IBE index. The IBE index can be associated with an EVM index, and when the value of the EVM index is different, the corresponding IBE index can also be different.

[0171] Optionally, when the value of the EVM index is the EVM index value corresponding to a Pi / 2 BPSK modulation mode, the value of the EVM index is larger, and in this case, the IBE index can also be referred to as a relaxed IBE index.

[0172] In the method, the terminal device needs to meet the IBE index used in each first interval when transmitting a signal based on each first interval and the first spectrum resource in the configuration bandwidth, which is beneficial to reduce the interference generated by the noise floor of each first interval to other spectrums, thereby improving the transmission performance of the communication system.

[0173] Optionally, for any first interval, no radio frequency index can be used in the first interval.

[0174] Further, for any configuration bandwidth, the terminal device can determine the MPR corresponding to the first interval based on the radio frequency index met by the other bandwidths other than the configuration bandwidth and the first interval supported by the configuration bandwidth.

[0175] Optionally, the radio frequency index met by the other bandwidths other than the configuration bandwidth and the first interval supported by the configuration bandwidth can be an out-of-band radio frequency index. The out-of-band radio frequency index met by the other bandwidths other than the configuration bandwidth and the first interval supported by the configuration bandwidth can include one or more of the following: ACLR, SEM, or SE.

[0176] In the method, the terminal device needs to meet the out-of-band radio frequency index when transmitting a signal, which is beneficial to avoid leaking more energy to the out-of-band spectrum resource, thereby improving the transmission performance of the communication system.

[0177] For example, assuming that the configuration bandwidth is 20 MHz, the subcarrier spacing is 15 kHz, and the length of the first interval is equal to 1 / 2 of the length of the configuration bandwidth, the area that needs to meet the out-of-band radio frequency index can be as shown in FIG. 7. In this example, the first interval includes the interval on one side of the configuration bandwidth.

[0178] Next, the present application will take the configuration bandwidth as 20 MHz, the subcarrier spacing as 15 kHz, and the length of the first interval as 1 / 2 of the length of the configuration bandwidth as an example to introduce the method for the terminal device to determine the first MPR.

[0179] As an example, assuming that the configuration bandwidth is 20 MHz, the subcarrier spacing is 15 kHz, and the length of the first interval is equal to 1 / 2 of the length of the configuration bandwidth, when no radio frequency index can be used in the first interval, the terminal device can calibrate the transmitter in the terminal device, so that when the terminal device transmits a signal based on the maximum transmission power determined by the first MPR corresponding to the first interval, the other bandwidths other than the configuration bandwidth and the first interval can meet the out-of-band radio frequency index.

[0180] Optionally, the terminal device can store the first MPR corresponding to the first interval into a storage system.

[0181] As another example, assuming that the configuration bandwidth is 20MHz, the subcarrier spacing is 15kHz, and the length of the first interval is equal to 1 / 2 of the length of the configuration bandwidth, when the IBE indicator is used in the first interval, the terminal device can calibrate the transmitter in the terminal device such that, when the terminal device transmits a signal based on the maximum transmission power determined based on the first MPR corresponding to the first interval, the bandwidths other than the configuration bandwidth and the first interval can satisfy the out-of-band radio frequency indicator, and the bandwidth in the first interval needs to satisfy the IBE indicator.

[0182] Optionally, the terminal device can store the first MPR corresponding to the first interval into a storage system.

[0183] As another example, assuming that the configuration bandwidth is 20MHz, the subcarrier spacing is 15kHz, and the length of the first interval is equal to 1 / 2 of the length of the configuration bandwidth, when the relaxed IBE indicator is used in the first interval, the terminal device can calibrate the transmitter in the terminal device such that, when the terminal device transmits a signal based on the maximum transmission power determined based on the first MPR corresponding to the first interval, the bandwidths other than the configuration bandwidth and the first interval can satisfy the out-of-band radio frequency indicator, and the bandwidth in the first interval needs to satisfy the relaxed IBE indicator.

[0184] Optionally, the terminal device can store the first MPR corresponding to the first interval into a storage system.

[0185] For any configuration bandwidth, the first MPR calculated by the terminal device based on the length of the first interval supported under the configuration bandwidth and / or the radio frequency indicator that can be used in the first interval can be smaller than the MPR used by the terminal device when determining the maximum transmission power for transmitting a signal on the frequency spectrum resources in the configuration bandwidth.

[0186] In a possible implementation, any one MPR represents an interval value. Assuming that the first interval value of the MPR used by the terminal device when determining the maximum transmission power for transmitting a signal on the frequency spectrum resources in the configuration bandwidth is ≦3.5, the second interval value of the first MPR determined by the terminal device based on the configuration bandwidth and the first interval supported by the configuration bandwidth can be within the first interval value. For example, the second interval value of the first MPR determined by the terminal device based on the configuration bandwidth and the first interval supported by the configuration bandwidth can be ≦2.5.

[0187] In another possible implementation, any one MPR represents an upper limit value. Assuming that the first upper limit value of the MPR that the terminal device adopts when determining the maximum transmission power when transmitting a signal on the frequency spectrum resource within the configuration bandwidth is 3.5, the second upper limit value of the first MPR determined by the terminal device based on the configuration bandwidth and the first interval supported by the configuration bandwidth can be less than the first upper limit value. For example, the second upper limit value of the first MPR determined by the terminal device based on the configuration bandwidth and the first interval supported by the configuration bandwidth can be 2.5.

[0188] In the sequel, embodiments of the present application will be described by taking any one MPR representing an upper limit value as an example.

[0189] Optionally, the first information can also be used to indicate one or more of the following information: the length of each first interval in the at least one first interval, or the radio frequency index used in each first interval.

[0190] Optionally, the information used to indicate the length of each first interval can include the ratio between the length of each first interval and the length of the configuration bandwidth, so that the terminal device transmits the ratio between the length of each first interval and the length of the configuration bandwidth to the network device, without the need to transmit the specific value of the length of each first interval to the network device, which is beneficial to reduce the transmission overhead when the terminal device and the network device transmit the first information.

[0191] Optionally, the information used to indicate the length of each first interval can include the specific value of the length of each first interval. In this way, the network device can quickly obtain the length of each first interval based on the first information, without the need for additional calculation, which can reduce some unnecessary calculation overhead.

[0192] In the method, in the sequel, embodiments of the present application will be described by taking the information used to indicate the length of each first interval as an example, which includes the ratio between the length of each first interval and the length of the configuration bandwidth.

[0193] As an example, for any one first interval, the ratio between the length of the first interval and the length of the configuration bandwidth can be 1 / 2, 1 / 3, 1 / 4, or 1 / 5.

[0194] For example, assuming that the configuration bandwidth is 20 MHz and the subcarrier spacing configuration is 15 kHz, the number of resource blocks occupied by full scheduling transmission is 106. Assuming that the length of the first interval supported by the configuration bandwidth indicated in the first information is 1 / 2 of the length of the configuration bandwidth. After receiving the first information, the network device can determine that the length of the first interval supported by the configuration bandwidth is 53 RBs, or 53*12*15 kHz = 9.54 MHz.

[0195] For example, assuming that the configuration bandwidth is 20MHz and the subcarrier spacing configuration is 15kHz, the number of resource blocks occupied by full scheduling transmission is 106. Assuming that the length of the first interval supported under the configuration bandwidth indicated in the first information is 1 / 4 of the length of the configuration bandwidth. After receiving the first information, the network device can determine that the length of the first interval supported under the configuration bandwidth is 27 RBs, or 27*12*15kHz=4.86MHz.

[0196] In the method, for any first interval, the radio frequency index used in the first interval indicated in the first information can be: using an IBE index, using a relaxed IBE index, or not using an index.

[0197] S602, the network device sends second information to the terminal device, and the second information is used to indicate one or more of the following information: the length of the target interval, or the radio frequency index used in the target interval, the length of the target interval or the radio frequency index used in the target interval corresponds to the second MPR, and the target interval is the translation distance of the starting point of the out-of-band radio frequency index constraint interval configured by the network device for the terminal device. Correspondingly, the terminal device receives the second information.

[0198] In the method, before the network device sends the second information to the terminal device, the second interval also needs to be determined, and then the target interval is determined based on the second interval.

[0199] Optionally, when the terminal device reports the first information to the network device, the first information also indicates the length of each first interval in at least one first interval and / or the radio frequency index used in each first interval, the second interval can be the interval with the smallest length in the at least one first interval, and / or the amplitude vector error under the modulation mode corresponding to the radio frequency index used in the second interval can be the smallest one in the at least one first interval, and / or the first MPR corresponding to the second interval can be the smallest MPR in the at least one first MPR.

[0200] In the method, the MPR corresponding to the second interval can be the second MPR. Or, the first interval corresponding to the second MPR can be the second interval.

[0201] In the method, when the first information sent by the terminal device to the network device is also used to indicate the length of each interval and / or the radio frequency index used in each first interval, the network device can select the first interval with the highest priority (for example, the first interval with the smallest interval length, and / or the amplitude vector error under the modulation mode corresponding to the radio frequency index is the smallest, and / or the corresponding MPR is the smallest) from the interval length and / or the radio frequency index used in each interval as the second interval based on the interval length and / or the radio frequency index used in each interval, which is conducive to obtaining the target interval with higher priority.

[0202] In a possible implementation, when the first information indicates the radio frequency index used in each first interval, after the network device determines the second interval from the at least one first interval, the network device can determine the length of the target interval based on the length of the second interval, and the length of the target interval can be equal to the length of the second interval.

[0203] In addition, the network device can also determine the radio frequency index used in the second interval as the radio frequency index used in the target interval.

[0204] In this implementation, the second information sent by the network device to the terminal device can indicate the length of the target interval and the radio frequency index used in the target interval.

[0205] As shown in FIG. 8, it is assumed that the first information reported by the terminal device to the network device can indicate the related information of two first intervals, and the two first intervals can include first interval 1 and first interval 2. The related information of each of the two first intervals can include the length of the first interval, the radio frequency index used in the first interval, and the first MPR corresponding to the first interval.

[0206] In this example, it is assumed that the length of the first interval 1 is 4.86 MHz, the radio frequency index used in the first interval 1 is the IBE index, and the first MPR corresponding to the first interval 1 is 2 dB. It is also assumed that the length of the first interval 2 is 9.54 MHz, the radio frequency index used in the first interval 2 is the relaxed IBE index, and the first MPR corresponding to the first interval 2 is 1.5 dB.

[0207] In this example, the network device can determine the first interval 1 as the second interval, and can determine that the length of the target interval is 4.86 MHz and the radio frequency index used in the target interval is the IBE index.

[0208] Optionally, the first information can also indicate the index of each first interval in the at least one first interval. Correspondingly, the second information sent by the network device to the terminal device can include the index of the second interval in the at least one first interval, and the length of the target interval and the radio frequency index used in the target interval can be indicated based on the index of the second interval.

[0209] In the embodiment shown in FIG. 8, each first interval can include an interval located on one side of the configuration bandwidth.

[0210] In another possible implementation, when the first information indicates the radio frequency index used in each first interval, after the network device determines the second interval from the at least one first interval, the network device can determine the length of the target interval based on the length of the second interval, and the length of the target interval can be less than the length of the second interval.

[0211] In this implementation, the second information sent by the network device to the terminal device can indicate the length of the target interval.

[0212] As shown in FIG. 9, as an example, it is assumed that the first information reported by the terminal device to the network device can indicate the related information of two first intervals, which can include the first interval 3 and the first interval 4. The related information of each of the two first intervals can include the length of the first interval and the first MPR corresponding to the first interval.

[0213] In this example, it is assumed that the length of the first interval 3 is 4.86 MHz, and the first MPR corresponding to the first interval 3 is 2 dB. It is also assumed that the length of the first interval 4 is 9.54 MHz, and the first MPR corresponding to the first interval 4 is 1.5 dB.

[0214] In this example, the network device can determine the first interval 3 as the second interval, and can determine that the length of the target interval can be less than 4.86 MHz. For example, the network device can determine the length of the target interval as 4 MHz.

[0215] In the embodiment shown in FIG. 9, each first interval can include an interval located on one side of the configuration bandwidth.

[0216] In S603, the terminal device determines the maximum transmission power of the signal based on the target MPR, the target MPR is equal to the second MPR, the second MPR is one of the at least one first MPR, or the target MPR is a linear interpolation between the second MPR and the third MPR, and the third MPR is an MPR used by the terminal device to determine the maximum transmission power when transmitting the signal on the second frequency spectrum resource within the configuration bandwidth.

[0217] In this method, for any one configuration bandwidth, the second frequency spectrum resource within the configuration bandwidth can be understood as: all or part of the frequency spectrum resource on the frequency spectrum resource occupied by the configuration bandwidth.

[0218] In this method, the target MPR can be determined by the terminal device based on the second information. In this method, the target interval indicated by the second information can be a target interval with a higher priority. In this way, when the terminal device performs signal transmission based on the target interval with the higher priority, the transmission performance of the communication system can be improved.

[0219] In a possible implementation, when the second information indicates the length of the target interval and the radio frequency index used in the target interval, the terminal device can first determine the second MPR from the at least one first MPR based on the length of the target interval and the radio frequency index used in the target interval, and then determine the target MPR based on the second MPR.

[0220] In this implementation, the length of the target interval can be equal to the length of the first interval corresponding to the second MPR, and the radio frequency index used in the target interval can be the same as the radio frequency index used in the first interval corresponding to the second MPR.

[0221] In this implementation, the target MPR is equal to the second MPR.

[0222] In combination with FIG. 8, it is assumed that the at least one first interval can include first interval 1 and first interval 2. Among them, the length of the first interval 1 is 4.86 MHz, the radio frequency index used in the first interval 1 is the IBE index, and the first MPR corresponding to the first interval 1 is 2 dB. The length of the first interval 2 is 9.54 MHz, the radio frequency index used in the first interval 2 is the relaxed IBE index, and the first MPR corresponding to the first interval 2 is 1.5 dB.

[0223] And it is assumed that the second information sent by the network device to the terminal device indicates that the length of the target interval is 4.86 MHz, and the radio frequency index used in the target interval is the IBE index.

[0224] In this example, the terminal device can determine the first interval 1 as the first interval (i.e., the second interval) corresponding to the second MPR, and determine the target MPR as the first MPR corresponding to the first interval 1, that is, determine the target MPR as 2 dB.

[0225] In this implementation, since the second MPR is obtained by the terminal device based on the first interval corresponding to the second MPR and the radio frequency index used in the first interval corresponding to the second MPR, and the target MPR is equal to the second MPR, the target MPR obtained based on this method is more accurate, thereby facilitating obtaining a more accurate maximum transmission power of the signal.

[0226] In another possible implementation, when the second information indicates the length of the target interval, the terminal device can first determine the second MPR from the at least one first MPR based on the length of the target interval, and then determine the target MPR based on the second MPR.

[0227] In this implementation, the first interval corresponding to the second MPR is one or more first intervals with the smallest length, and the one or more first intervals are the first intervals with lengths greater than the length of the target interval in the at least one first interval.

[0228] In combination with FIG. 9, it is assumed that the at least one first interval can include first interval 3 and first interval 4. Among them, the length of the first interval 3 is 4.86 MHz, and the first MPR corresponding to the first interval 3 is 2 dB. The length of the first interval 4 is 9.54 MHz, and the first MPR corresponding to the first interval 4 is 1.5 dB.

[0229] In this example, it is assumed that the length of the target interval indicated in the second information sent by the network device to the terminal device is 4MHz. Then the terminal device can determine that the lengths of the two first intervals are both greater than 4MHz, and then determine the first interval 3 with the smallest length among the two first intervals as the first interval corresponding to the second MPR.

[0230] In this implementation, the target MPR can be equal to the linear interpolation between the second MPR and the third MPR.

[0231] As an example, the linear difference value formula between the second MPR and the third MPR can satisfy the following formula:

[0232] Wherein, Y represents the length of the target interval, X represents the length of the first interval corresponding to the second MPR (i.e. the second interval), S1 represents the second MPR, and S0 represents the third MPR.

[0233] In this implementation, since the length of the target interval can be smaller than the length of the second interval, the length of the target interval configured by the network device can be smaller, which is beneficial to improve the utilization rate of spectrum resources, thereby improving the transmission performance of the communication system.

[0234] In this method, the method for the terminal device to determine the maximum transmission power of the signal based on the target MPR can refer to the method for determining the maximum transmission power of the signal in the existing protocol, which will not be described here.
